technical field

The present application relates to the field of communication technologies, and in particular, to a communication method and a communication device.

Background technique

Currently, in the new radio release 16 (NR-Rel-16) protocol, the user equipment (user equipment, UE) performs downlink positioning measurement tasks in the measurement window (measurement gap, MG). MG parameters (for example, MG period, MG duration, etc.) are configured by the base station to the UE through an RRC message. Currently, the UE needs to measure the positioning reference signals (positioning reference signals, PRS) from the serving cell and the PRS of the non-serving cell, so as to meet the multiple downlink positioning methods supported in the NR-Rel-16 protocol. For example, downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AOD). The phase position between the PRS resources of the serving cell and the PRS resources of the non-serving cell is determined by the expected reference signal time difference (expected reference signal time difference, expected RSTD) and The uncertainty of the expected reference signal arrival time difference (expected RSTD uncertainty) determination.

However, if some PRS resources are not in the MG, the UE needs to request the base station to configure the MG. Currently, the MG request is initiated by the UE through RRC signaling, and then the base station configures the corresponding MG for the UE. Therefore, the configuration process of the MG takes a lot of time. Introduce MG-free localization measurement in NR-Rel-17 protocol to improve the efficiency of localization measurement.

However, when there is no MG positioning measurement, the data service of the terminal equipment and the positioning measurement service of the non-serving cell exist simultaneously. If there is a conflict between the data service and the positioning measurement service, the service may be prioritized or discarded. It is worth considering how the base station should schedule the data of the terminal equipment in the scenario of no MG positioning measurement to improve the data scheduling performance.

It is convenient for the access network device to determine at which time domain positions of the terminal device there may be data scheduling restrictions, and it is beneficial for the access network device to reasonably perform data scheduling of the terminal device.

In another possible implementation, the method also includes:

According to the expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the non-serving cell uncertainty, the expected reference signal arrival time difference information of the serving cell and the expected reference signal arrival time difference information of the serving cell The time difference information determines a first time domain location.

The terminal device determines all possible time domain ranges where the PRS of the non-serving cell falls according to the expected time difference of arrival information of the non-serving cell and the uncertain expected time difference of arrival information of the non-serving cell of the terminal device. The terminal device determines the time domain position occupied by the PRS of the serving cell according to the expected reference signal arrival time difference information of the serving cell and the uncertain expected reference signal arrival time difference information of the serving cell.

It is convenient for the access network device to determine at which time domain positions of the terminal device there may be data scheduling restrictions, and it is beneficial for the access network device to reasonably perform data scheduling of the terminal device.

In another possible implementation manner, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

In this implementation manner, the terminal device may further indicate the data scheduling restriction on the time domain position occupied by the PRS of the serving cell.

In another possible implementation, the terminal device uses the expected reference signal difference of arrival information of the non-serving cell, the expected reference signal difference of arrival information of the uncertainty of the non-serving cell, the expected reference signal difference of arrival information of the serving cell, and the serving cell The uncertainty of the expected reference signal arrival time difference information to determine the first time-domain position, including:

In this implementation manner, a specific manner for the terminal device to determine the first time-domain position is provided, which facilitates the implementation of the solution. On the other hand, the terminal device combines the expected reference signal arrival time difference information corresponding to the non-serving cell, the uncertain expected reference signal arrival time difference information and the expected reception time difference threshold to determine that the time domain position occupied by the PRS of the non-serving cell has data scheduling restrictions The time domain location is beneficial to accurately determine the time domain location with data scheduling constraints. Therefore, it is convenient for the access network device to determine at which time domain positions of the terminal device there may be data scheduling restrictions, and it is beneficial for the access network device to reasonably perform data scheduling of the terminal device.

In another possible implementation manner, the terminal device is based on the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, the expected time difference of arrival information of the serving cell, the serving cell The expected reference signal arrival time difference information of the uncertainty and the expected reception time difference threshold determine the first time domain position, including:

In another possible implementation manner, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold.

In this implementation manner, the first time domain position corresponds to a time domain position occupied by a PRS of a non-serving cell whose receiving time difference is less than or equal to the expected receiving time difference threshold. For a non-serving cell whose receiving time difference exceeds the expected receiving time difference threshold, the terminal device cannot perform positioning measurement on the PRS of the non-serving cell. Therefore, what the access network device needs to consider is the data scheduling limitation at the time domain position occupied by the PRS of the non-serving cell whose receiving time difference is less than or equal to the expected receiving time difference threshold.

In another possible implementation manner, the capability information includes scheduling restriction information. If the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions, the scheduling restriction information is also used to indicate that the expected reference signal arrival time difference information of the non-serving cell and the non-serving cell The uncertain expected reference signal arrival time difference information of the serving cell determines a first time domain position, and the terminal device has data scheduling restrictions at the first time domain position.

In this possible implementation, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions, and is also used to indicate data scheduling restrictions, so that the access network device can reasonably and effectively perform data scheduling of the terminal device, and improve data scheduling. performance. Therefore, it is convenient for the access network device to refer to the information to determine the first time domain position with data scheduling restrictions. It is conducive to the reasonable and effective data scheduling of the access network equipment, ensuring the normal operation of services with higher priority on the terminal equipment, and improving the scheduling performance.

In this possible implementation manner, the scheduling restriction information further indicates that the first time domain position is determined in combination with the first information, and indicates the data scheduling restriction at the first time domain position to the access network device. It is convenient for the access network device to determine at which time domain positions of the terminal device there may be data scheduling restrictions, and it is beneficial for the access network device to reasonably perform data scheduling of the terminal device.

In another possible implementation manner, the first time domain position includes N1 time domain symbols before the start time domain symbol occupied by the PRS of the serving cell, and/or, the end time domain symbol located at the end of the PRS occupation of the serving cell For the next N2 time domain symbols, N1 and N2 are integers greater than 0, and the N1 time domain symbols and N2 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell of the terminal device.

In this possible implementation, the first time domain position includes N1 time domain symbols before the start time domain symbol occupied by the PRS of the serving cell, and/or after the end time domain symbol occupied by the PRS of the serving cell N2 time-domain symbols of . A possible form of the first time domain position is provided. Since the access network device cannot determine the time domain position occupied by the PRS of the non-serving cell, there may be a terminal device at the time domain position occupied by the PRS of the non-serving cell. The data service conflicts with the PRS of the non-serving cell. It is convenient for the access network device to determine at which time domain positions of the terminal device there may be data scheduling restrictions, and it is beneficial for the access network device to reasonably perform data scheduling of the terminal device.

In another possible implementation manner, the capability information includes an expected receiving time difference threshold, and the expected receiving time difference threshold is used to determine a second time domain position, where the terminal device has data scheduling restrictions;

Wherein, the second time domain position includes a third time domain position located before and continuous to the start time domain position of the PRS occupation of the serving cell, and a third time domain position located after the end time domain position of the PRS occupation of the serving cell and The fourth time domain position continuous with the end time domain position, the duration of the third time domain position and the duration of the fourth time domain position are respectively equal to the duration of the expected receiving time difference threshold.

In this implementation manner, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions, and the expected receiving time difference threshold may be used to determine the second time domain position with data scheduling restrictions. Therefore, it is convenient for the access network device to determine which time domain positions need to consider data scheduling restrictions. Secondly, it can be known from the second time domain position above that for the access network device, it cannot perceive the time domain position occupied by the PRS of the non-serving cell, and can only detect the non-serving cell whose receiving time difference falls within the expected receiving time difference threshold range. The PRS of the cell performs positioning measurement. Therefore, the terminal device can reasonably indicate the time domain position with data scheduling restriction through the expected receiving time difference threshold.

In another possible implementation manner, the capability information further includes scheduling restriction information, and the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions. In this implementation, if the scheduling restriction information indicates that there is data scheduling restriction, then the access network device determines the time domain position with data scheduling restriction in combination with other information (such as the expected receiving time difference threshold).

In another possible implementation manner, the receiving time difference is the time difference between the first initial time domain position and the second initial time domain position;

The first initial time domain position is the initial time domain position of the initial subframe occupied by the PRS of the serving cell; the second initial time domain position is the initial time domain position of the initial subframe occupied by the PRS of the non-serving cell;

The first starting time domain position is determined according to the expected reference signal arrival time difference information of the serving cell and/or the uncertain expected reference signal arrival time difference information of the serving cell;

The second starting time domain position is determined according to the expected reference signal arrival time difference information of the non-serving cell and/or the uncertain expected reference signal arrival time difference information of the non-serving cell.

In this implementation manner, the specific meaning of the receiving time difference is further shown, and the receiving time difference is defined by the time difference between the first initial time domain position and the second initial time domain position. The time-domain positions that are beneficial for the terminal device or the access network device to determine which PRSs of the non-serving cells are occupied need to consider data scheduling restrictions. For example, if the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is greater than the expected receiving time difference threshold, then the time domain position occupied by the PRS of the non-serving cell does not consider data scheduling restrictions. If the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is less than or equal to the expected receiving time difference threshold, the time domain position occupied by the PRS of the non-serving cell needs to consider data scheduling restrictions.

In another possible implementation, the first initial time domain position is located at the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, and the second initial time domain position is located at the expected reference signal arrival time difference information of the non-serving cell at the corresponding time domain location; or,

The first initial time domain position is located at the moment corresponding to the first duration before the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, and the second initial time domain position is located at the expected reference signal arrival time difference information corresponding to the non-serving cell At the moment corresponding to the first second duration of the corresponding time domain position, the first duration is determined according to the expected reference signal arrival time difference information of the uncertainty of the serving cell, and the second duration is determined according to the expected uncertainty of the non-serving cell. determined by reference to signal time difference of arrival information; or,

The first initial time domain position is located at the first moment, and the second initial time domain position is located at the second moment;

If the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell is before the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, the first moment is the time domain corresponding to the expected reference signal arrival time difference information of the serving cell The time corresponding to the last first time length of the location, the second time is the time corresponding to the first second time length of the time domain position corresponding to the expected reference signal arrival time difference information corresponding to the non-serving cell, and the first time length is based on the difference of the serving cell The deterministic expected reference signal arrival time difference information is determined, and the second duration is determined according to the non-serving cell's uncertain expected reference signal arrival time difference information; or,

If the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell is after the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, the first moment is the time corresponding to the expected reference signal arrival time difference information of the serving cell The time corresponding to the first time length before the domain position, and the second time is the time corresponding to the second time length of the time domain position corresponding to the expected reference signal arrival time difference information corresponding to the non-serving cell; the first time length is based on the serving cell The uncertain expected reference signal arrival time difference information is determined, and the second duration is determined according to the uncertain expected reference signal arrival time difference information of the non-serving cell.

The above provides several possible ways of defining the first initial time domain position and the second initial time domain position, which is beneficial for the terminal device or access network device to determine the first initial time domain position of the serving cell and each non-serving cell The corresponding second starting time domain position.

In another possible implementation manner, the terminal device determines capability information, including:

The terminal device determines the scheduling restriction information in combination with whether it supports concurrent capabilities of the terminal device's data service and positioning measurement service without an MG.

In another possible implementation manner, the terminal device determines scheduling restriction information according to the concurrency capability of the terminal device, including:

If the terminal device supports concurrent data services and positioning measurement services of the terminal device without an MG, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restrictions;

If the terminal device does not support concurrent data services and positioning measurement services of the terminal device without an MG, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions.

In this implementation, a specific process is provided for the terminal device to determine the scheduling restriction information in combination with whether the terminal device supports the concurrency capability of the terminal device's data service and positioning measurement service without a measurement window. For example, in a low-frequency scenario, the terminal device supports concurrent data services and positioning measurement services (that is, the terminal device receives data and PRS at the same time), and the scheduling restriction information is used to indicate that the terminal device has no scheduling restrictions. In a high-frequency scenario, the terminal device does not support concurrent data services and positioning measurement services, and the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions.

the expected receive time difference threshold is equal to 0.5 milliseconds; or,

The length of the expected reception time difference threshold is not limited.

In another possible implementation, the method also includes:

The terminal device receives the physical downlink control channel (PDCCH) from the access network device; the terminal device analyzes the PDCCH, and determines the initial time domain position of the PDSCH sent by the access network device to the terminal device; if the start of the PDSCH The initial time domain position falls on the first time domain position, and the time interval between the initial time domain position occupied by the PDCCH and the initial time domain position of the PDSCH is less than M time domain symbols or N time slots, then the terminal equipment The PDSCH is ignored or not processed, the M is an integer greater than or equal to 0, and the N is an integer greater than or equal to 0.

In this implementation, if the access network device does not schedule the PDCCH M time domain symbols or N time slots ahead of the start time domain position of the PDSCH, the terminal device may choose to ignore the PDSCH.

In this implementation, if the access network device does not schedule the PDCCH M time domain symbols or N time slots ahead of the start time domain position of the PDSCH, the terminal device may choose to ignore the PDSCH. The terminal device may directly process the positioning measurement service at the second time domain position first.

In another possible implementation, the method also includes:

In this possible implementation, the second information is used to indicate that the terminal device needs M time domain symbols or N time slots after the PDCCH of the terminal device, which is beneficial for the access network device to schedule the PDCCH in combination with the second information. It is avoided that when the data service and the positioning measurement service conflict, the terminal device has not determined the location of the data in time, causing the terminal device to process the positioning service first and discard the data. Then, when the priority of the data service is high, the priority of the data service cannot be guaranteed.

In another possible implementation manner, the value of M is 7, 14, 28, 42, or 56; the value of N is 1, 2, 3, or 4.

In another possible implementation manner, the second information is included in capability information. In this implementation manner, the terminal device may report the second information through capability information. That is, the second information may belong to a capability of the terminal device.

In this implementation, the terminal device receives first indication information from the access network device, and the first indication information is used to indicate that the PRS is preferentially processed or the data of the terminal device is preferentially stored within R time domain symbols after the PDCCH of the terminal device . In this way, the access network device restricts the behavior of the terminal device according to the importance of the data service, and prevents the terminal device from instructing the terminal device to process the positioning measurement service first because the data service is not perceived in advance.

A wireless terminal device may be a device that provides voice and/or data connectivity to a user, or a handheld device with a wireless connection function, or other processing device connected to a wireless modem.

Terminal equipment, also known as user equipment (UE), mobile station (mobile station, MS), mobile terminal (mobile terminal, MT), etc., includes wireless communication functions (providing voice/data connectivity to users) devices, such as handheld devices with wireless connectivity, or vehicle-mounted devices. At present, examples of some terminal devices are: mobile phone (mobile phone), tablet computer, notebook computer, palmtop computer, mobile internet device (mobile internet device, MID), wearable device, virtual reality (virtual reality, VR) device, enhanced Augmented reality (AR) equipment, wireless terminals in industrial control, wireless terminals in Internet of Vehicles, wireless terminals in self driving, wireless terminals in remote medical surgery , a wireless terminal in a smart grid, a wireless terminal in a transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc. For example, the wireless terminal in the Internet of Vehicles may be a vehicle-mounted device, a complete vehicle device, a vehicle-mounted module, a vehicle, and the like.

Some technical terms involved in this application are introduced below.

1. Serving cell: the cell where the terminal device currently resides.

2. Non-serving cell: refers to a cell whose global cell identifier (CGI) is different from the CGI of the serving cell of the terminal device.

3. Reference cell: It is a serving cell or a non-serving cell of the terminal device. Taking the time domain position occupied by the reference cell as the reference time domain position, the PRS of the serving cell or the PRS of the non-serving cell is mapped to the corresponding time domain of the reference cell position, so as to determine the time domain position to which the PRS of the non-serving cell is mapped on the serving cell.

4. Measurement gap (MG): The access network device can configure MG for the terminal device. When the terminal device is in the connected state, the terminal device can perform the same-frequency or different-frequency downlink positioning measurement task in the MG. In the MG, the terminal equipment suspends the service transmission of the serving cell, and adjusts the receiver of the terminal equipment to the frequency point of the target cell to perform downlink positioning and measurement tasks. At the end of the MG time, the terminal equipment transfers the receiver to the serving cell to continue the data service.

5. Positioning processing window (PRS processing window, PPW): refers to the time window used for terminal equipment to perform positioning measurement tasks.

6. Expected reference signal arrival time difference information (expected RSTD): the time domain position corresponding to the center point of the search window used to determine the initial time domain position where the PRS of a cell is located. The search window refers to the time range where the initial time domain position of the PRS may fall. For example, as shown in FIG. 2, for the non-serving cell 1, the initial time-domain position corresponding to the expected reference signal arrival time difference information is the time-domain position corresponding to the center point of the search window of the non-serving cell 1, that is The start time domain position of the first half search window of the non-serving cell or the end time domain position of the second half search window of the non-serving cell.

7. Uncertain expected reference signal arrival time difference information (expected RSTD uncertainty): used to determine the length of the half search window where the PRS of the cell is located. The uncertain expected time difference of arrival information of the cell and the expected time difference of arrival information of the cell determine the time domain positions where the two half search windows of the cell are located.

8. System frame number offset (SFN-offset): including sfn-Offset and integer subframe offset (integerSubframeOffset).

sfn-Offset refers to the SFN offset of the transmission reception point (transmission reception point, TRP) antenna position between the reference cell and the non-serving cell. The SFN offset corresponds to the non-serving cell from the beginning of the radio frame #0 of the reference cell The number of complete radio frames (one radio frame is 10ms (milliseconds)) of the latest radio frame #0.

The integer subframe offset refers to the subframe boundary offset of the TRP antenna position between the reference small area non-serving cells, counted in complete subframes, which is counted from the beginning of subframe #0 of the reference cell to the non-serving cell Start of nearest subframe #0, rounded down to multiple of subframes.

9. Positioning reference signal resource set slot offset (dl-PRS-ResourceSlotOffset): refers to the slot offset of the first downlink slot in the cell's PRS resource set relative to the slot where the radio frame SFN#0 is located.

10. Positioning reference signal symbol offset (dl-PRS-ResourceSymbolOffset): refers to the initial time domain symbol of the cell's PRS in the time slot determined by the time slot offset of the positioning reference signal resource set.

Currently, in the NR-Rel-16 protocol, the terminal device performs the downlink positioning measurement task in the MG. MG parameters (for example, MG period, MG duration, etc.) are configured by the access network device to the terminal device through a radio resource control (radio resource control, RRC) message. At present, the terminal device needs to measure the PRS from the serving cell and the PRS from the non-serving cell, so as to satisfy multiple downlink positioning methods supported in the NR-Rel-16 protocol. For example, DL-TDOA, DL-AOD. The terminal device can determine the time domain resource occupied by the PRS of the serving cell and the time domain resource occupied by the PRS of the non-serving cell through the expected time difference of arrival time difference information and the uncertain time difference information of the reference signal arrival in the positioning assistance data configured by the positioning management device. The relative position between domain resources. However, if some PRS resources are not in the MG, the UE needs to request the base station to configure the MG. Currently, the MG request is initiated by the UE through RRC signaling, and then the base station configures the corresponding MG for the UE. Therefore, the configuration process of the MG takes a lot of time.

Introduce MG-free localization measurement in NR-Rel-17 protocol to improve the efficiency of localization measurement. At present, the access network 1#107 (RAN 1#107, R1#107) stipulates that in order to complete the PRS measurement of the non-serving cell under the condition of no MG, certain synchronization conditions need to be met. Specifically, the synchronization relationship between the serving cell and the non-serving cell is constrained by constraining the expected Rx timing difference. Wherein, the expected receiving time difference refers to the time difference between the time when the terminal device receives the PRS of the serving cell and the time when the terminal device receives the PRS from the non-serving cell.

In addition, it is stipulated in R#107 that if the terminal equipment supports MG-less positioning measurement, within the PPW, the terminal equipment can report the following capability 1 or capability 2 to determine the priority of the PRS. Two possible capabilities of the terminal device are introduced below by taking the priority of the PRS higher than that of other downlink signals as an example. The priority of the PRS is lower than that of other downlink signals, which is similar and will not be explained here.

Capability 1: On all time-domain symbols in the PPW, the priority of the positioning measurement service is higher than that of all other downlink signals.

Wherein, capability 1 includes capability 1A and capability 1B.

Capability 1A includes: in the PPW, if there is a PRS on a carrier (component carrier, CC), the downlink signals on all CCs in the PPW will be affected, that is, the priority of the PRS on all CCs is higher than that of other downlinks The priority of the signal.

Capability 1B includes: in the PPW, there is a PRS on a bandwidth (band), only the downlink signals on this bandwidth are affected, and the downlink signals on other bandwidths are not affected, that is, the priority of the PRS on this bandwidth is higher than that of The priority of other downlink signals.

Capability 2: Only on the time-domain symbol where the PRS is located, the priority of the PRS is higher than that of other downlink signals.

At present, the communication protocol supports the ability of the terminal device to process the PRS with three priorities, and specifically supports the following options.

Option 1: End-devices can indicate support for both priority states.

Wherein, the two priority states include state 1 and state 2. State 1: The priority of PRS is higher than that of all physical downlink control channels (physical downlink control channel, PDCCH), physical downlink shared channel (physical downlink shared channel, PDSCH), channel status information reference signal (channel status information reference signal, CSI-RS ). State 2: PRS has a lower priority than all PDCCH, PDSCH, and CSI-RS.

Option 2: End-devices can indicate support for three priority states.

Wherein, the three priority states include state 1, state 2 and state 3. State 1: PRS priority is higher than all PDCCH, PDSCH, CSI-RS. State 2: PRS priority is lower than PDCCH and ultra reliable low latency communication physical downlink shared control channel (ultra reliable low latency communication physical downlink shared channel, URLLC PDSCH), priority is higher than other PDSCH, CSI-RS. State 3: PRS priority is lower than all PDCCH, PDSCH, CSI-RS.

Option 3: The terminal device can support a single priority state, specifically, the priority of the PRS is higher than that of all PDCCH, PDSCH, and CSI-RS.

In this application, the data service of the terminal device includes at least one of the following: PDCCH, PDSCH, and CSI-RS (for example, AP-CSI-RS).

However, in the scenario without MG positioning measurement, since the access network equipment of the serving cell cannot perceive the time domain position occupied by the PRS of the non-serving cell, the positioning measurement service of the non-serving cell will conflict with the data service of the serving cell. Currently, terminal equipment does not support processing data services and positioning measurement services at the same time. On the other hand, the communication protocol does not specify the scheduling restrictions of the access network equipment in the MG-less positioning measurement scenario. Therefore, how the access network device schedules the data of the terminal device in the MG-free positioning measurement scenario is a problem worth considering.

The present application provides a corresponding technical solution for the access network device to determine the data scheduling limit of the terminal device, so that the access network device can reasonably and effectively perform data scheduling of the terminal device, and improve data scheduling performance. For details, please refer to the related introduction of the embodiments shown in FIG. 3 , FIG. 7 , FIG. 8 and FIG. 12 below.

The technical solutions of the present application are described below in combination with specific embodiments.

FIG. 3 is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application. See Figure 3, methods include:

301. The terminal device determines capability information of the terminal device.

Wherein, the capability information includes at least one of the following items: scheduling restriction information, expected receiving time difference threshold.

The expected receiving time difference threshold is the maximum receiving time difference supported by the terminal device. The expected receiving time difference threshold is related to the capability of the terminal equipment.

Optionally, the length of the expected receiving time difference threshold includes any of the following:

The expected reception time difference threshold is equal to the length of the CP; or,

The expected reception time difference threshold is equal to 0.5 slots; or,

The length of the expected reception time difference threshold is not limited.

For example, in PRS measurement without MG, the expected receiving time difference threshold is a capability of the terminal equipment, and the value of the expected receiving time difference threshold can be any of the following: {length of CP, length of one time domain symbol, 0.5 time slot , the length of half a time-domain symbol, infinite (infinite)}.

It should be noted that, the above length of the expected receiving time difference threshold is only an example, and does not belong to a limitation on the length of the expected receiving time difference threshold. For example, the length of the expected receiving time difference threshold may also be a length of 0.4 time slots, a length of two time domain symbols, or 0.5 milliseconds, etc., which are not limited in this application.

The reception time difference is a measure that describes the level of synchronization between the serving and non-serving cells. The receiving time difference is the time difference between the first reference time of the serving cell and the second reference time of the non-serving cell.

Optionally, the receiving time difference may be determined by the expected reference signal arrival time difference information of the non-serving cell and the uncertain expected reference signal arrival time difference information. In the low-frequency scenario (ie, FR1), the range corresponding to the uncertain expected reference signal arrival time difference information is -32us to 32us. In the high-frequency scenario (ie, FR2), the range corresponding to the uncertain expected reference signal arrival time difference information is -8us to 8us.

Some possible implementations of the first reference time and the second reference time are introduced below.

1. The first reference time is located at the initial time domain position where the first time slot is located, the time domain position corresponding to the first duration before the initial time domain position where the first time slot is located, or the initial time domain position where the first time slot is located The time domain position of the first time length after the time domain position; the second reference time is located at the initial time domain position where the second time slot is located, and the time of the second time length pair before the initial time domain position where the second time slot is located The domain position, or the time domain position of the second time length after the initial time domain position where the second time slot is located.

The first time slot is one of the time slots occupied by the serving cell, and the second time slot is the closest time slot to the initial time domain position where the first time slot is located among the time slots occupied by the non-serving cell. The first duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the serving cell. The second duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the non-serving cell.

For example, as shown in FIG. 4A , the start time domain position of the second time slot is the start time domain position T0 of the time slot where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second time slot is located is T1, and the time domain position corresponding to the second duration after the initial time domain position where the second time slot is located is T2. The second duration is the length of the half search window of the non-serving cell. The first time slot is the closest time slot to T0 among the time slots occupied by the serving cell, that is, the initial time domain position where the first time slot is located is T4 as shown in FIG. 4A . Therefore, if the second reference time is T0 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T0. If the second reference time is T1 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T1. If the second reference time is T2 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T2.

For example, as shown in FIG. 4B , the start time domain position of the second time slot is the start time domain position T0 of the time slot where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second time slot is located is T1, and the time domain position corresponding to the second duration after the initial time domain position where the second time slot is located is T2. The second duration is the length of the half search window of the non-serving cell. The first time slot is the closest time slot to T0 among the time slots occupied by the serving cell, that is, the initial time domain position where the first time slot is located is T4 as shown in FIG. 4A . The start time domain position of the first time slot is the start time domain position T4 of the time slot where the time domain position corresponding to the serving cell is located. The time domain position corresponding to the first time length before the initial time domain position where the first time slot is located is T5, and the time domain position corresponding to the first time length after the initial time domain position where the first time slot is located is T6. The first duration is the length of half the search window of the serving cell.

For non-serving cells, we recommend using the starting time domain position of the slot plus the search window as the second reference time. This means that when calculating the receiving time difference, it is assumed that the PRS of the non-serving cell starts to transmit from the first time domain symbol of the second time slot, no matter which time domain symbol of the second time slot is actually configured to start transmission.

In a possible implementation manner, the first time slot is a time slot of the serving cell, the second time slot is a time slot of the non-serving cell, and the receiving time difference may be defined as the maximum value of X1 and X2. As shown in FIG. 4A , X1 is the distance between T1 and the initial time domain position T4 where the first time slot is located, and X2 is the distance between T2 and the initial time domain position T4 where the first time slot is located. That is, the receiving time difference of the non-serving cell is T4-T2, that is, Q.

Specifically, X1'=mod (the expected RSTD uncertainty of the non-serving cell+the expected RSTD uncertainty of the non-serving cell, the length of the time slot), and mod is modulus. If X1' is less than 0.5 time slots, then X1=X1', otherwise, X1=1-X1'. X2'=mod (the expected RSTD uncertainty of the non-serving cell-the expected RSTD uncertainty of the non-serving cell, the length of the time slot), mod is modulus. If X2' is less than 0.5 slots, then X2=X2', otherwise, X2=1-X2'.

In another possible time slot mode, the first time slot is one of the time slots occupied by the PRS of the serving cell, and the second time slot is the closest to the second time slot among the time slots occupied by the PRS of the non-serving cell A time slot of , the receiving time difference is X1'-X2'.

X1'=sfn-Offset of the serving cell+integerSubframeOffset of the serving cell+expected RSTD of the serving cell+ResourceSetSlotOffset of the serving cell+dl-PRS-ResourceSlotOffset of the serving cell+expected RSTD uncertainty of the serving cell; or, X1'=sfn-Offset of the serving cell+serving cell integerSubframeOffset+expected RSTD of the serving cell+ResourceSetSlotOffset of the serving cell+dl-PRS-ResourceSlotOffset of the serving cell-expected RSTD uncertainty of the serving cell.

X2' = sfn-Offset of the non-serving cell + integerSubframeOffset of the non-serving cell + expected RSTD of the non-serving cell + ResourceSetSlotOffset of the non-serving cell + dl-PRS-ResourceSlotOffset of the non-serving cell + expected RSTD uncertainty of the non-serving cell; or, X2' = non-serving sfn-Offset of the cell+integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell+ResourceSetSlotOffset of the non-serving cell+dl-PRS-ResourceSlotOffset of the non-serving cell-expected RSTD uncertainty of the non-serving cell.

2. The first reference time is located at the initial time domain position where the first time domain symbol is located, the time domain position corresponding to the first time length before the initial time domain position where the first time domain symbol is located, or where the first time domain symbol is located The second reference time is located at the initial time domain position where the second time domain symbol is located, and the first time domain position before the initial time domain position where the second time domain symbol is located. The time-domain position of the two-time-length pair, or the time-domain position of the second time-length pair after the initial time-domain position where the second time-domain symbol is located.

The first time domain symbol is one of the time domain symbols occupied by the serving cell, and the second time domain symbol is the one closest to the initial time domain position where the first time domain symbol is located among the time domain symbols occupied by the non-serving cell A time domain symbol. The first duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the serving cell. The second duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the non-serving cell.

For example, as shown in FIG. 4C , the start time domain position of the second time domain symbol is the start time domain position T0 of the time domain symbol where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second time domain symbol is located is T1, and the time domain corresponding to the second duration after the initial time domain position where the second time domain symbol is located The location is T2. The second duration is the length of the half search window of the non-serving cell. The first time domain symbol is the time domain symbol closest to T0 among the time domain symbols occupied by the serving cell, that is, the initial time domain position where the first time domain symbol is located is T4 as shown in FIG. 4C . Therefore, if the second reference time is T0 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T0. If the second reference time is T1 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T1. If the second reference time is T2 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T2.

For example, as shown in FIG. 4D , the start time domain position of the second time domain symbol is the start time domain position T0 of the time domain symbol where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second time domain symbol is located is T1, and the time domain corresponding to the second duration after the initial time domain position where the second time domain symbol is located The location is T2. The second duration is the length of the half search window of the non-serving cell. The first time-domain symbol is the closest time-domain symbol to T0 among the time-domain symbols occupied by the serving cell, that is, the initial time-domain position where the first time-domain symbol is located is T4 as shown in FIG. 4D . The time domain position corresponding to the first time length before the initial time domain position where the first time domain symbol is located is T5, and the time domain corresponding to the first time length after the initial time domain position where the first time domain symbol is located The location is T6. The first duration is the length of half the search window of the serving cell.

In a possible implementation, the first time domain symbol is a time domain symbol of the serving cell, the second time domain symbol is a time domain symbol of the non-serving cell, and the receiving time difference can be defined as the maximum value of X1 and X2. Wherein, X1 is the distance between T1 and the initial time domain position T4 where the first time domain symbol is located, and X2 is the distance between T2 and the initial time domain position T4 where the first time domain symbol is located. That is, the receiving time difference of the non-serving cell is T4-T2, that is, Q.

Specifically, X1'=mod (the expected RSTD of the non-serving cell+the expected RSTD uncertainty of the non-serving cell, the time-domain symbol length), and mod is modulus. If X1' is less than 0.5 time-domain symbols, then X1=X1', otherwise, X1=1-X1'. X2'=mod (the expected RSTD of the non-serving cell-the expected RSTD uncertainty of the non-serving cell, the time-domain symbol length), mod is modulo. If X2' is less than 0.5 time-domain symbols, then X2=X2', otherwise, X2=1-X2'.

In another possible slot mode, the first time domain symbol is one of the time domain symbols occupied by the PRS of the serving cell, and the second time domain symbol is one of the time domain symbols occupied by the PRS of the non-serving cell. The receiving time difference of the nearest time domain symbol of the second time domain symbol is X1'-X2'.

X1' = sfn-Offset of the serving cell + integerSubframeOffset of the serving cell + expected RSTD of the serving cell + ResourceSetSlotOffset of the serving cell + dl-PRS-ResourceSlotOffset of the serving cell + dl-PRS-ResourceSymbolOffset of the serving cell + expected RSTD uncertainty of the serving cell; or, X1' = sfn-Offset of the serving cell + integerSubframeOffset of the serving cell + expected RSTD of the serving cell + ResourceSetSlotOffset of the serving cell + dl-PRS-ResourceSlotOffset of the serving cell + dl-PRS-ResourceSymbolOffset of the serving cell - expected RSTD uncertainty of the serving cell.

X2' = sfn-Offset of the non-serving cell + integerSubframeOffset of the non-serving cell + expected RSTD of the non-serving cell + ResourceSetSlotOffset of the non-serving cell + dl-PRS-ResourceSlotOffset of the non-serving cell + dl-PRS-ResourceSymbolOffset of the non-serving cell + expected RSTD of the non-serving cell uncertainty; or, X2'=sfn-Offset of the non-serving cell+integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell+ResourceSetSlotOffset of the non-serving cell+dl-PRS-ResourceSlotOffset of the non-serving cell+dl-PRS-ResourceSymbolOffset of the non-serving cell-non-serving cell The expected RSTD uncertainty of the serving cell.

3. The first reference time is located at the initial time domain position where the first radio frame is located, the time domain position corresponding to the first duration before the initial time domain position where the first radio frame is located, or the initial time domain position where the first radio frame is located The time domain position of the first time length after the time domain position; the second reference time is located at the initial time domain position where the second radio frame is located, and the time of the second time domain position before the initial time domain position where the second radio frame is located The domain position, or the time domain position corresponding to the second duration after the initial time domain position where the second radio frame is located.

The first radio frame is one of the radio frame numbers occupied by the serving cell, and the second radio frame is a radio frame closest to the initial time domain position where the first radio frame is located among the radio frames occupied by the non-serving cell. The first duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the serving cell. The second duration is the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the non-serving cell.

For example, as shown in FIG. 4E , the start time domain position of the second radio frame is the start time domain position T0 of the radio frame where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second wireless frame is located is T1, and the time domain position corresponding to the second duration after the initial time domain position where the second wireless frame is located is T2. The second duration is the length of the half search window of the non-serving cell. The first radio frame is the radio frame closest to T0 in the time domain symbols occupied by the serving cell, that is, the initial time domain position where the first radio frame is located is T4 in FIG. 4E . Therefore, if the second reference time is T0 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T0. If the second reference time is T1 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T1. If the second reference time is T2 and the first reference time is T4, the receiving time difference of the non-serving cell is T4-T2.

For example, as shown in FIG. 4F , the start time domain position of the second radio frame is the start time domain position T0 of the radio frame where the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell is located. The time domain position corresponding to the first second duration of the initial time domain position where the second wireless frame is located is T1, and the time domain position corresponding to the second duration after the initial time domain position where the second wireless frame is located is T2. The second duration is the length of the half search window of the non-serving cell. The first radio frame is the radio frame closest to T0 among the radio frames occupied by the serving cell, that is, the initial time domain position where the first radio frame is located is T4 as shown in FIG. 4F . The time domain position corresponding to the first duration before the initial time domain position where the first wireless frame is located is T5, and the time domain position corresponding to the first duration after the initial time domain position where the first wireless frame is located is T6. The first duration is the length of half the search window of the serving cell.

In a possible implementation manner, the first radio frame is a radio frame of the serving cell, the second radio frame is a radio frame of the non-serving cell, and the receiving time difference may be defined as the maximum value of X1 and X2.

Wherein, X1 is the distance between T1 and the initial time domain position T4 where the first radio frame is located, and X2 is the distance between T2 and the initial time domain position T4 where the first radio frame is located. That is, the receiving time difference of the non-serving cell is T4-T2, that is, Q.

Specifically, X1'=mod (integerSubframeOffset+non-serving cell's expected RSTD+non-serving cell's expected RSTD uncertainty, frame length (frame length) (10ms)), mod is modulus. If X1' is less than 0.5 radio frames, then X1=X1', otherwise, X1=1-X1'. X2'=mod (integerSubframeOffset+non-serving cell's expected RSTD-non-serving cell's expected RSTD uncertainty, frame length (frame length) (10ms)), mod is modulus. If X2' is less than 0.5 radio frames, then X2=X2', otherwise, X2=1-X2'.

In another possible implementation manner, if the first radio frame is radio frame 0 of the serving cell and the second radio frame is radio frame 0 of the non-serving cell, the receiving time difference may be defined as the maximum value of X1 and X2.

Specifically, X1'=mod(sfn-Offset of the non-serving cell+integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell+expected RSTD uncertainty of the non-serving cell, 10240ms). If X1' is less than 0.5 radio frames, then X1=X1', otherwise, X1=1-X1'. X2'=mod(sfn-Offset of the non-serving cell+integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell-expected RSTD uncertainty of the non-serving cell, 10240ms). mod is modulo. If X2' is less than 0.5 radio frames, then X2=X2', otherwise, X2=1-X2'.

In another possible time slot mode, if the first radio frame is one of the radio frames occupied by the PRS of the serving cell, and the second radio frame is one of the radio frames occupied by the PRS of the non-serving cell, then The reception time difference can be defined as X1'-X2'.

X1'=integerSubframeOffset of the serving cell+expected RSTD of the serving cell+expected RSTD uncertainty of the serving cell; or, X1'=integerSubframeOffset of the serving cell+expected RSTD of the serving cell-expected RSTD uncertainty of the serving cell.

X2'=integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell+expected RSTD uncertainty of the non-serving cell; or, X2'=integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell-expected RSTD uncertainty of the non-serving cell.

In another possible time slot mode, if the first radio frame is the radio frame 0 occupied by the PRS of the serving cell, and the second radio frame is the radio frame 0 occupied by the PRS of the non-serving cell, then the receiving time difference can be defined as X1' -X2'.

X1'=sfn-Offset of the serving cell+integerSubframeOffset of the serving cell+expected RSTD of the serving cell+expected RSTD uncertainty of the serving cell; or, X1'=sfn-Offset of the serving cell+integerSubframeOffset of the serving cell+expected RSTD of the serving cell-expected of the serving cell RSTD uncertainty.

X2'=sfn-Offset of the non-serving cell+integerSubframeOffset of the non-serving cell+expected RSTD of the non-serving cell+expected RSTD uncertainty of the non-serving cell; or, X2'=sfn-Offset of the non-serving cell+integerSubframeOffset of the non-serving cell+integerSubframeOffset of the non-serving cell expected RSTD - expected RSTD uncertainty of the non-serving cell.

It can be seen that, for the serving cell, the first reference time may be the initial time domain position where the time domain symbol of the serving cell is located, the initial time domain position where the time slot is located, the initial time domain position where the subframe is located, the radio frame The initial time domain position where it is located, or the initial time domain position where radio frame 0 is located. For a non-serving cell, the second reference time may be the initial time domain position where the time domain symbol of the non-serving cell is located, the initial time domain position where the time slot is located, the initial time domain position where the subframe is located, the starting time domain position where the radio frame is located The initial time domain position, or the initial time domain position where radio frame 0 is located. If the first reference time is the initial time domain position where the time domain symbol of the serving cell is located, and the second reference time is the initial time domain position where the time domain symbol of the non-serving cell is located, then the restrictions imposed on the network side are minimal. That is, as long as there is time-domain symbol level synchronization between the serving cell and the non-serving cell (that is, the first time-domain symbol and the second time-domain symbol are less than or equal to the expected receiving time difference threshold), the terminal device can measure the non-serving cell PRS. On the contrary, if the first reference time is the radio frame 0 of the serving cell, and the second reference time is the radio frame 0 of the non-serving cell, then the restrictions imposed on the network side are the most. That is, time-domain symbol-level synchronization has the least restriction on the network side, slot-level synchronization or subframe-level synchronization has less restriction on the network side, and wireless frame-level synchronization has the largest restriction on the network side.

We propose to use the initial time domain position where the time slot of the serving cell is located as the first reference time of the serving cell. Although it is technically the best choice to adopt the initial time domain position where the time domain symbol of the serving cell is located, there are the following problems when defining the receiving time difference. Problem 1: The symbol lengths of all time-domain symbols are not the same, because in a time slot, the CPs corresponding to time-domain symbol #0 and time-domain symbol #7 are longer than the CPs of other symbols in the time slot. Problem 2: The length of the search window corresponding to the non-serving cell may be larger than the length of the time-domain symbol, which makes it difficult to define the distance between the first reference time and the second reference time of the serving cell. Therefore, it is a possible choice to select the initial time domain position where the first time slot of the serving cell is located as the first reference time, which has less restrictions on the network side.

For the selection of the expected reception time difference threshold, the symbol-level synchronization required for MG-free positioning measurement depends on how the terminal device performs time of arrival (TOA) measurement. If the TOA measurement is done by time-domain correlation, the expected reception time difference threshold should not depend on any condition of synchronization between the serving cell and the non-serving cell. That is, the terminal device should be able to support any reception time difference between the PRS of the serving cell and the PRS of the non-serving cell, which is the same assumption as the MG-based measurement. In this case, the expected receiving time difference threshold may be 0.5 time slots.

If the TOA measurement is performed in the frequency domain after a fast Fourier transform (FFT), the expected reception time difference threshold should depend on the synchronization condition between the serving cell and the non-serving cell. Because the FFT window is likely to be based on serving cell timing. This case is similar to the CSI-RS L3 measurement with a single FFT assumption. For CSI-RS L3 measurements, accuracy requirements are defined in terms of time offset less than or equal to CP, and we believe that the same condition can be reused, which is already for networks with subcarrier spacing (SCS) greater than 15kHz strict requirements. Of course, the impact on timing-related measurement accuracy can be further discussed in the performance section at RAN4.

Considering that there may be different implementation options, we propose to define the synchronization threshold (that is, the threshold of expected receiving time difference) adopted in the positioning measurement without MG as the capability of the terminal equipment. The value of the expected receiving time difference threshold can be any of the following {CP length, 0.5 time slot}. This will expand the applicable scenarios of MG-free positioning measurement based on terminal equipment, that is, the MG-free positioning measurement can be used by some terminal equipment without tight synchronization requirements of network equipment.

The scheduling restriction information is used to indicate the data scheduling restriction of the terminal device.

Several possible ways in which the scheduling restriction information indicates the data scheduling restriction of the terminal device are introduced below.

1. The scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions; or, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restrictions.

For example, when the value of the scheduling restriction information is "0", it is used to indicate that the terminal device has no data scheduling restriction. When the value of the scheduling restriction information is "1", it is used to indicate that the terminal device has a data scheduling restriction. Alternatively, when the value of the scheduling restriction information is "1", it is used to indicate that the terminal device has no data scheduling restriction. When the value of the scheduling restriction information is "0", it is used to indicate that the terminal device has a data scheduling restriction.

Optionally, the scheduling restriction information is used to indicate that the terminal device has a data scheduling restriction, and the scheduling restriction information is also used for at least one of the positioning assistance information of the serving cell, the positioning assistance information of the non-serving cell, and the positioning assistance information of the reference cell A first time domain location is determined. For the positioning assistance information of the serving cell, the positioning assistance information of the non-serving cell, the positioning assistance information of the reference cell and the first time domain position, please refer to the related introduction later.

2. The scheduling restriction information is used to indicate that the terminal device has a data scheduling restriction at the first time domain position. For the position of the first time domain, please refer to the related introduction later.

302. The terminal device sends capability information of the terminal device.

Optionally, the terminal device sends the capability information to the access network device or the location management device.

In a possible implementation manner, the terminal device sends the capability information to the access network device through RRC signaling.

In another possible implementation manner, the terminal device sends the capability information to the positioning management device through LTE definition protocol (LTE positioning protocol, LPP) signaling.

In this implementation manner, after the location management device receives the capability information, the location management device may send the capability information to the access network device.

On the other hand, after the location management device receives the capability information, the location management device can combine the capability information to determine which non-serving cell PRS the terminal device can perform location measurement on, and combine the capability information to configure the PRS resources of the non-serving cell. For example, if the receiving time difference of the non-serving cell is less than or equal to the expected receiving time difference threshold, the positioning management device may determine that the terminal device can perform positioning measurement on the PRS of the non-serving cell. If the receiving time difference of the non-serving cell is greater than the expected receiving time difference threshold, the positioning management device may determine that the terminal device cannot perform positioning measurement on the PRS of the non-serving cell.

303. The access network device acquires capability information of the terminal device.

In a possible implementation manner, based on an implementation manner in which the terminal device sends capability information to the access network device, the above step 303 specifically includes: the access network device receives the capability information from the terminal device.

In another possible implementation manner, based on an implementation manner in which the terminal device sends capability information to the location management device, the above step 303 specifically includes: the access network device receives the capability information sent from the location management device.

304. The access network device determines the data scheduling restriction of the terminal device based on the capability information.

The above step 304 will be described below in combination with the capability information. In the following, the non-serving cells of the terminal device include the first non-serving cell as an example for introduction, and the processing procedures for other non-serving cells are also similar, and details are not described here one by one.

1. The capability information includes the expected receiving time difference threshold. Optionally, the foregoing step 304 specifically includes step 304a and step 304b.

304a. The access network device determines an eighth time domain position based on the expected receiving time difference threshold.

Specifically, the access network device determines the eighth time domain position according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell, and the expected receiving time difference threshold.

Several possible implementation manners for the access network device to determine the eighth time domain position are introduced below.

Implementation method one

Step 1a to step 1d are described below to introduce the first implementation.

Step 1a, the access network device determines that the receiving time difference corresponding to the first non-serving cell is less than or equal to the expected receiving time difference threshold;

In this implementation manner, the access network device determines the receiving time difference corresponding to the first non-serving cell. For specific definitions of the receiving time difference, please refer to the foregoing introduction. If the access network device determines that the receiving time difference corresponding to the first non-serving cell is less than or equal to the expected receiving time difference threshold, it can be considered that the terminal device can perform positioning measurement on the PRS of the first non-serving cell. Therefore, the access network device needs to consider the data scheduling restriction on the time domain position occupied by the PRS of the first non-serving cell.

It should be noted that if the receiving time difference corresponding to the first non-serving cell is greater than the expected receiving time difference threshold, the terminal device will not perform positioning measurement on the PRS of the first non-serving cell. Therefore, the access network device does not need to consider data scheduling restrictions on the time domain position occupied by the PRS of the first non-serving cell.

Step 1b. The access network device determines, according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell, where the PRS of the first non-serving cell is mapped on the serving cell. The second time domain position of ;

Optionally, the serving cell is synchronized with the first serving cell, that is, the network is synchronized; or, the serving cell is different from the first serving cell, that is, the network is not synchronized. Step 1b will be described below combining these two situations.

Case 1, the serving cell is synchronized with the first serving cell, then the time domain position occupied by the PRS of the serving cell of the terminal device is the same as the time domain position occupied by the PRS of the non-serving cell of the terminal device.

Based on this, optionally, the above step 1b specifically includes:

The access network device determines the second time domain position to which the PRS of the first non-serving cell is mapped on the serving cell according to the positioning assistance information of the serving cell.

Wherein, the positioning assistance information of the serving cell includes at least one of the following: information of the expected time difference of arrival of the uncertainty of the serving cell, resource set time slot offset, positioning reference signal resource time slot offset, positioning reference signal resource symbol offset Shift and position reference signal duration time domain symbols. The time domain position occupied by the PRS of the serving cell of the terminal device is the same as the time domain position occupied by the PRS of the non-serving cell of the terminal device. Therefore, the second time domain position is the time domain position occupied by the PRS of the serving cell.

For example, as shown in FIG. 5A , the access network device may determine the second time domain location by using the positioning assistance information of the serving cell.

Case 2: The serving cell is not synchronized with the first serving cell. In this case, there are two possible situations:

Case A: The reference cell is the serving cell.

Based on situation A, optionally, the above step 1b specifically includes:

The access network device determines, according to the positioning assistance information of the serving cell and the positioning assistance information of the first non-serving cell, the second time domain position to which the PRS of the first non-serving cell is mapped on the serving cell.

Wherein, the positioning assistance information of the serving cell includes at least one of the following: information of the expected time difference of arrival of the uncertainty of the serving cell, resource set time slot offset, positioning reference signal resource time slot offset, positioning reference signal resource symbol offset Shift and position reference signal duration time domain symbols.

The positioning assistance information of the first non-serving cell includes: the system frame number SFN offset of the first non-serving cell, expected reference signal arrival time difference information, uncertain expected reference signal arrival time difference information, resource set time slot offset, positioning Reference signal resource time slot offset, positioning reference signal resource symbol offset, positioning reference signal duration time domain symbol.

Case B: the reference cell is neither the serving cell nor the first serving cell.

Based on case B, optionally, the above step 1b specifically includes:

The access network device determines the second time-domain position to which the PRS of the first non-serving cell is mapped on the serving cell according to the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell.

Wherein, the positioning assistance information of the serving cell includes at least one of the following: system frame number offset of the serving cell, expected reference signal arrival time difference information, uncertain expected reference signal arrival time difference information, resource set time slot offset, positioning reference The signal resource time slot offset, the positioning reference signal resource symbol offset, and the positioning reference signal duration time domain symbol.

The positioning assistance information of the first non-serving cell includes: the system frame number offset of the first non-serving cell, expected reference signal arrival time difference information, uncertain expected reference signal arrival time difference information, resource set time slot offset, positioning reference The signal resource time slot offset, the positioning reference signal resource symbol offset, and the positioning reference signal duration time domain symbol.

The positioning assistance information of the reference cell includes at least one of the following: information of the expected time difference of arrival of the uncertainty of the serving cell, resource set time slot offset, positioning reference signal resource time slot offset, positioning reference signal resource symbol offset, The positioning reference signal lasts for time-domain symbols.

For example, as shown in Figure 5A, the PRS of the first non-serving cell maps to 2.98 on time domain symbol 2 to 6.98 on time domain symbol 6 of the serving cell.

Based on the implementation of the above case 2, the embodiment shown in FIG. 3 further includes step 303a, and step 303a may be performed before step 304.

303a. The access network device acquires the positioning assistance information of the non-serving cell.

In a possible implementation manner, the terminal device sends the positioning assistance information of the non-serving cell to the access network device. Correspondingly, the above step 303a specifically includes: the access network device receives the positioning assistance information of the non-serving cell from the terminal device.

In another possible implementation manner, the location management device sends the location assistance information of the non-serving cell to the access network device. Correspondingly, the above step 303a specifically includes: the access network device receives the positioning assistance information of the non-serving cell from the positioning management device.

The positioning assistance information of the non-serving cell includes positioning assistance information of the first non-serving cell. For positioning assistance information, please refer to the previous introduction.

Step 1c, the access network device determines a third time domain position and a fourth time domain position according to the second time domain position and the uncertain expected reference signal arrival time difference information of the first non-serving cell;

Wherein, the third time domain position is located before the start time domain position of the second time domain position and is continuous with the start time domain position, and the fourth time domain position is located after the end time domain position of the second time domain position and is the same as the end time position The domain positions are continuous, and the duration of the third time domain position and the fourth time domain position are equal to the length of the half search window corresponding to the uncertain expected reference signal arrival time difference information of the first non-serving cell.

For example, as shown in Figure 5A, the length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the first non-serving cell is 0.02 ms, and the third time domain position is located at 2.96 to 2.96 ms on time domain symbol 2. Between 2.98 on domain symbol 2, the fourth time domain position is between 6.98 on time domain symbol 6 and the initial time domain position where time domain symbol 7 is located.

Step 1d, the access network device takes the second time domain position, the third time domain position and the fourth time domain position as the eighth time domain position.

For example, as shown in FIG. 5A , the access network device uses the time domain position between 2.96 on time domain symbol 2 and the initial time domain position where time domain symbol 7 is located as the eighth time domain position.

Optionally, after step 1d, the access network device may round up the eighth time domain position at the symbol level to obtain the rounded eighth time domain position.

For example, as shown in Figure 5B, the access network device rounds up the time domain position between 2.96 on time domain symbol 2 and the initial time domain position where time domain symbol 7 is located, at the symbol level to the time domain position where time domain symbol 3 is located. The initial time domain position of to the initial time domain position where the time domain symbol 7 is located. That is, the rounded eighth time domain position includes the initial time domain position where time domain symbol 3 is located to the initial time domain position where time domain symbol 7 is located.

Optionally, for the case where the serving cell is not synchronized with the first non-serving cell, optionally, the first implementation above further includes steps 1e to 1f.

Step 1e, the access network device determines the fifth time-domain position occupied by the PRS of the serving cell according to the positioning assistance information of the serving cell; for the positioning assistance information of the serving cell, please refer to the relevant introduction above.

For example, as shown in FIG. 5C , the access network device determines that the fifth time-domain position is time-domain symbol 1 to time-domain symbol 5 through the positioning assistance information of the serving cell.

Step 1f, the access network device determines the sixth time domain position and the seventh time domain position according to the expected reference signal arrival time difference information of the fifth time domain position and the uncertainty of the serving cell;

The length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the serving cell is 0.04ms, so as shown in Figure 5C, the sixth time domain position is from 0.96 on time domain symbol 0 to time domain symbol 1 The initial time domain position where the seventh time domain position is located is from the initial time domain position where time domain symbol 5 is to 5.04 on time domain symbol 5.

Based on this, optionally, the above step 1d specifically includes:

The access network device uses the second time domain position, the third time domain position and the fourth time domain position as the eighth time domain position, including:

For example, as shown in FIG. 5C , the eighth time domain position includes 0.96 on time domain symbol 0 to the initial time domain position where time domain symbol 7 is located.

Optionally, the access network device rounds up the eighth time domain position at the symbol level to obtain the rounded eighth time domain position. For example, as shown in Figure 5C, the access network device rounds up the time domain position between 0.96 on time domain symbol 0 and the initial time domain position where time domain symbol 7 is located, and obtains time domain symbol 1 From the initial time domain position where the time domain symbol 7 is located to the initial time domain position where the time domain symbol 7 is located. That is to say, the eighth time domain position includes the initial time domain position where time domain symbol 1 is located to the initial time domain position where time domain symbol 7 is located.

Step 2a to step 2d are described below to introduce the second implementation.

Step 2a, the access network device determines that the receiving time difference corresponding to the first non-serving cell is less than or equal to the expected receiving time difference threshold;

Step 2b: The access network device determines, according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell, where the PRS of the first non-serving cell is mapped on the serving cell The second time domain position of ;

The above step 2a to step 2b are similar to the above step 1a to step 1b, for details, please refer to the related introduction of step 1a to step 1b, which will not be repeated here.

Step 2c. If the receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, the access network device takes the second time domain position as the eighth time domain position.

For example, as shown in FIG. 5A , the second time domain positions include 2.98 on time domain symbol 2 to 6.98 on time domain symbol 6 . If the receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, the access network device directly uses the second time domain position as the eighth time domain position.

Optionally, the second time domain position falls on time domain symbol L-1 to time domain symbol L+N-1, where N is the time domain symbol occupied by the PRS of the first non-serving cell. If the receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, the length of the second time domain position falling on the time domain symbol L-1 is less than the length of the CP, and the second time domain position falls on the time domain symbol L+ The length on N1-1 is greater than the length of CP. The access network device may perform symbol-level rounding up on the second time domain position, and then the rounded second time domain position includes time domain symbol L to time domain symbol L+N−1.

For example, time domain symbol L−1 is time domain symbol 2, and time domain symbol L+N−1 is time domain symbol 6. The receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, and the second time domain position falls on the initial time domain position from 2.98 of time domain symbol 2 to time domain symbol 3, and the second time domain position falls on The length on the time domain symbol 2 is smaller than the length of the CP, so the access network device does not need to have data scheduling restrictions on the time domain symbol 2. Therefore, the access network device may have data scheduling restrictions from the initial time domain position where time domain symbol 3 is located to the end time domain position where time domain symbol 6 is located (the initial time domain position where time domain symbol 7 is located).

Step 2d. If the receiving time difference corresponding to the first non-serving cell is greater than the length of the CP, the access network device determines the third time difference according to the expected reference signal arrival time difference information of the second time domain position and the uncertainty of the first non-serving cell. The domain position and the fourth time domain position, and the second time domain position, the third time domain position and the fourth time domain position are used as the eighth time domain position.

For example, as shown in Figure 5A, if the receiving time difference corresponding to the first non-serving cell is greater than the length of the CP, the access network device uses the second time domain position, the third time domain position and the fourth time domain position as the eighth time domain position domain location.

Optionally, the second time domain position falls on time domain symbol L-1 to time domain symbol L+N-1, where N is the time domain symbol occupied by the PRS of the first non-serving cell. If the receiving time difference corresponding to the first non-serving cell is greater than the length of the CP, in addition to the time domain symbol L to the time domain symbol L+N-1, the time domain symbol L-1 and the time domain symbol L+N may also have data scheduling Limitation, the length of the half search window of the first non-serving cell needs to be further considered here.

For example, as shown in FIG. 5A , the second time domain position falls on time domain symbol 2 through time domain symbol 6 . The length of the half search window corresponding to the expected reference signal arrival time difference information of the uncertainty of the first non-serving cell is 0.02ms, and the third time domain position is between 2.96 on time domain symbol 2 and 2.98 on time domain symbol 2 , the fourth time domain position is between 6.98 on time domain symbol 6 and the initial time domain position where time domain symbol 7 is located. Thus, the eighth time domain symbol includes 2.96 on time domain symbol 2 to the end time domain position of time domain symbol 6 (ie the starting time domain position where time domain symbol 7 is located).

Step 3a to step 3c are described below to introduce the third implementation.

Step 3a, the access network device determines the second time domain position occupied by the PRS of the serving cell according to the positioning assistance information of the serving cell;

Step 3a is similar to the aforementioned step 2a, for details, please refer to the related introduction of the aforementioned step 2a.

In the third implementation manner, the serving cell is synchronized with the first serving cell, that is, the network is synchronized. Then the time domain position occupied by the PRS of the serving cell of the terminal device is the same as the time domain position occupied by the PRS of the non-serving cell of the terminal device.

Step 3b, the access network device determines the ninth time domain position and the tenth time domain position according to the second time domain position and the expected receiving time difference threshold;

Wherein, the ninth time domain position is located before the start time domain position of the second time domain position and is continuous with the start time domain position, and the tenth time domain position is located after the end time domain position of the second time domain position and is at the same time as the end time domain position The domain positions are continuous; the duration of the ninth time domain position and the tenth time domain position are both equal to the expected receiving time difference threshold.

For example, as shown in Figure 5D, the length of the expected receiving time difference threshold is 0.5ms, the ninth time domain position is located between 2.48ms on time domain symbol 2 and 2.98 on time domain symbol 2, and the tenth time domain position is when Between 6.98 on symbol 6 in the domain and 7.48 on symbol 7 in the time domain.

In step 3c, the access network device takes the second time domain position, the ninth time domain position and the tenth time domain position as the eighth time domain position.

For example, as shown in FIG. 5D , the access network device determines that the eighth time domain position includes 2.58 on time domain symbol 2 to 7.48 on time domain symbol 7 .

Optionally, the access network device may round up the eighth time domain position at the symbol level to obtain the rounded eighth time domain position.

For example, based on FIG. 5D , the access network device may determine the rounded eighth time domain position including: time domain symbol 2 to time domain symbol 7 by determining the eighth time domain position.

Step 4a to step 4d are described below to introduce the fourth implementation.

Step 4a, the access network device determines the second time domain position occupied by the PRS of the serving cell according to the positioning assistance information of the serving cell;

Step 4a is similar to the aforementioned step 2a, for details, please refer to the related introduction of the aforementioned step 2a.

Step 4b. If the receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, the access network device takes the second time domain position as the eighth time domain position.

Step 4c, if the receiving time difference corresponding to the first non-serving cell is greater than the length of the CP, the access network device determines the ninth time domain position and the tenth time domain position according to the second time domain position and the expected receiving time difference threshold, and the second The time domain position, the ninth time domain position and the tenth time domain position serve as the eighth time domain position.

Step 4b to step 4c are similar to the aforementioned steps 2c to 2d, for details, please refer to the aforementioned related introduction.

304b. The access network device determines the data scheduling restriction of the terminal device at the eighth time domain position.

Specifically, if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the eighth time domain position, that is, the access network device The data of the terminal device is not scheduled at the eighth time domain position; or, if the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the first time domain position There are no data scheduling restrictions on end devices.

2. Capability information includes scheduling restriction information.

1. The scheduling restriction information is used to indicate that the terminal device has a data restriction or is used to indicate that the terminal device has no data scheduling restriction. Optionally, the capability information also includes an expected receiving time difference threshold.

Case 1: The scheduling restriction information is used to indicate that the terminal device has no data scheduling restriction.

In case 1, the above step 304 specifically includes: the access network device determines, based on the scheduling restriction information, that the terminal device has no data scheduling restriction.

Case 2: The scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions.

The scheduling restriction information is used to indicate that the first time domain position is determined according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the non-serving cell, and the positioning assistance information of the reference cell and the expected receiving time difference threshold.

Optionally, the above step 304 specifically includes step 304c to step 304d.

Step 304c, the access network device determines the first time domain position according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell and the expected receiving time difference threshold.

The specific determination method of step 304c is similar to that described above in the first or second implementation method. For details, please refer to the relevant introduction of the first or second implementation method, and will not be repeated here.

Step 304d, the access network device determines the data scheduling restriction of the terminal device at the first time domain position.

Step 304d is similar to the above-mentioned step 304b, for details, please refer to the related introduction of the above-mentioned step 304b, which will not be repeated here.

The specific determination process is similar to the aforementioned step 304b, for details, please refer to the related introduction of the aforementioned step 304b, which will not be repeated here.

Optionally, the embodiment shown in FIG. 3 further includes step 303b.

303b. The terminal device sends the first information to the access network device. Correspondingly, the access network device receives the first information from the terminal device.

The first information is used to indicate that the terminal equipment needs M time domain symbols or N time slots after the PDCCH of the terminal equipment. M is an integer greater than or equal to 0, and N is an integer greater than or equal to 0.

Optionally, the value of M may be 7, 14, 28, 42, or 56; the value of N may be 1, 2, 3, or 4.

It should be noted that, in the communication protocol, the value of M may be at least one of the above 7, 14, 28, 42, and 56. The value of N can be at least one of the above 1, 2, 3, 4. For example, the value of M is {7, 14, 28, 42}. The value of N is {1,2,3}. Alternatively, the value of M is {7, 14, 28, 42, 56}, and the value of N is {1, 2, 3, 4}.

It should be noted that M and N may also take other values, which are not limited in this application. For example, the value of M can be 10, 15, 30, or 70, etc., and the value of N can be 5, 6, or 7, etc.

It should be noted that, this embodiment does not limit the type of the CP in the PDCCH, and this application does not specifically limit it. For example, normal cyclic prefix (normal CP) or extended cyclic prefix (extended CP).

It should be noted that the time unit required by the terminal device after the PDCCH of the terminal device is described above using M time domain symbols or N time slots as the time unit. In practical applications, the technical solution of this application does not limit the time unit used . For example, time units such as subframes or minutes may also be used.

Optionally, the M time domain symbols or N time slots are used for the terminal device to parse the downlink control information (DCI) carried in the PDCCH and determine the time for the behavior of the terminal device on a certain time domain symbol. The value of M is related to the analysis and processing capabilities of the terminal equipment.

For example, the terminal device parses the DCI and determines that there is a PDSCH on the Xth time domain symbol. The terminal device needs to determine whether there is a PRS on the X+1th time domain symbol, and determine whether the terminal device is on the X+1th time domain symbol in combination with the priority of the positioning measurement service of the terminal device and the priority of the data service of the terminal device performed business. The time required for the terminal device to determine the behavior on the X-th time-domain symbol should be before the X-th time-domain symbol, that is to say, the above-mentioned M time-domain symbols or N time slots should include the time for the terminal device to resolve the information carried in the PDCCH The DCI and the terminal device determine the time of the terminal device's behavior on a certain time domain symbol, so that the terminal device can select a service with a higher priority for processing at the Xth time domain symbol, thereby ensuring the service priority of the terminal device.

It should be noted that, optionally, when M or N is equal to 0, it means that the terminal device supports concurrent data services and positioning measurement services, that is, the terminal device can receive data and PRS at the same time, without requiring the access network device to schedule the PDCCH in advance. For example, in a low-frequency scenario, a terminal device can receive data and PRS at the same time. When M or N is greater than 0, the terminal device does not support concurrent data services and positioning measurement services, that is, the terminal device cannot receive data and PRS at the same time. For example, when a terminal device is in a high-frequency scenario, the terminal device cannot receive data and PRS at the same time through the same beam.

It should be noted that the above step 303b is only an exemplary manner. In practical applications, the terminal device may also carry the first information in the capability information and report it to the access network device, that is, the first information belongs to a kind of capability information of the terminal device. Alternatively, the value of M or N in the first information may also be predefined or preconfigured by the communication protocol, which is not limited in this application.

Optionally, the terminal device may also send the first information to the location management device.

In this implementation manner, optionally, the first information is included in the capability information. That is, the terminal device may send the first information to the location management device through the above step 302 .

Optionally, the location management device may send the first information to the access network device.

There is no fixed order of execution between step 303b and steps 302 to 304, step 303b can be executed first, and then step 302 to step 304; or, step 302 to step 304 is executed first, and then step 303b is executed; or, depending on the situation, at the same time Execute step 303b and step 302 to step 304.

Optionally, the embodiment shown in FIG. 3 further includes step 305, and step 305 may be performed after step 304.

305. The access network device schedules the PDCCH of the terminal device in advance of M time domain symbols or N time slots relative to the third initial time domain position.

The third initial time domain position is the initial time domain position at which the access network device sends the PDSCH or AP-CSI-RS to the terminal device, and the third initial time domain position falls on the eighth time domain position.

For example, as shown in Figure 6, the eighth time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell, and the third initial time domain position falls in the time domain position of the non-serving cell 1. In the time domain position occupied by the PRS. The access network device schedules the PDCCH of the terminal device M time domain symbols or N time slots ahead of the third initial time domain position.

Optionally, the embodiment shown in FIG. 3 further includes step 306 and step 307 .

306. The terminal device determines a first time domain position.

Optionally, the terminal device determines the first time domain position according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference cell, and the positioning assistance information of the first non-serving cell.

The reference cell is the serving cell or a non-serving cell of the terminal device.

Several possible implementation manners for the terminal device to determine the first time domain position are introduced below.

Implementation mode 1 is introduced below in combination with steps 5a to 5d.

Step 5a, the terminal device determines that the receiving time difference corresponding to the first non-serving cell is less than or equal to the expected receiving time difference threshold;

Step 5b: The terminal device determines the location of the PRS mapped on the serving cell according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell. second time domain position;

Step 5c, the access network device determines a third time domain position and a fourth time domain position according to the second time domain position and the uncertain expected reference signal arrival time difference information of the first non-serving cell;

Step 5d, the access network device takes the second time domain position, the third time domain position and the fourth time domain position as the eighth time domain position.

Steps 5a to 5d are similar to the aforementioned steps 1a to 1d, for details, please refer to the relevant introduction of the aforementioned steps 1a to 1d.

In this implementation, the first time domain location is the same as the eighth time domain location.

For the case where the serving cell is not synchronized with the first non-serving cell, optionally, the above implementation 1 further includes steps 5e to 5f.

Step 5e, the access network device determines the fifth time domain position occupied by the PRS of the serving cell according to the positioning assistance information of the serving cell;

Step 5f, the access network device determines the sixth time domain position and the seventh time domain position according to the expected reference signal arrival time difference information of the fifth time domain position and the uncertainty of the serving cell;

The above step 5e to step 5f are similar to the above step 1e and step 1f, for details, please refer to the related introduction of the above step 1e and step 1f.

Based on this, optionally, the above step 5d specifically includes:

The terminal device takes the second time domain position, the third time domain position and the fourth time domain position as the first time domain position, including:

For related examples of step 5d, reference may be made to the introduction of related examples of step 1d above, which will not be repeated here.

Implementation mode 2 is described below in conjunction with steps 6a to 6d.

Step 6a, the access network device determines that the receiving time difference corresponding to the first non-serving cell is less than or equal to the expected receiving time difference threshold;

Step 6b: The access network device determines, according to at least one of the positioning assistance information of the serving cell, the positioning assistance information of the reference signal, and the positioning assistance information of the first non-serving cell, where the PRS of the first non-serving cell is mapped on the serving cell The second time domain position of ;

Step 6c. If the receiving time difference corresponding to the first non-serving cell is less than or equal to the length of the CP, the terminal device takes the second time domain position as the first time domain position.

Step 6d: If the receiving time difference corresponding to the first non-serving cell is greater than the length of the CP, the terminal device determines the third time-domain position according to the second time-domain position and the uncertain expected reference signal arrival time difference information of the first non-serving cell and the fourth time domain position, and the second time domain position, the third time domain position and the fourth time domain position are used as the first time domain position.

Steps 6a to 6d are similar to the aforementioned steps 2a to 2d. For details, please refer to the relevant introductions of the aforementioned steps 2a to 2d, and will not be repeated here.

307. The terminal device determines the positioning measurement behavior and the data sending and receiving behavior at the first time domain position.

Optionally, if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the terminal device receives the PRS at the first time domain position, and does not receive the PRS from the access network device data; or,

If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, and the PDSCH or AP-CSI-RS of the terminal device falls on the first time domain position, the starting time domain position of the PDCCH is the same as that of the PDSCH or the time interval between the initial time domain positions of AP-CSI-RS is less than M time domain symbols or N time slots, then the terminal device ignores or does not process the PDSCH or AP-CSI-RS, and the terminal device at the first PRS measurement is performed at the domain position, M is an integer greater than or equal to 0, and the PDCCH is used to determine the initial time domain position of the PDSCH or AP-CSI-RS.

In the case that the priority of the positioning measurement service of the terminal device is higher than that of the data service of the terminal device, the terminal device will discard data on the time domain symbols occupied by the PRS in the PPW. For scheduling restriction requirements, in addition to the time domain symbols occupied by the PRS of the serving cell, the terminal device does not want to receive data on the time domain symbols mapped from the PRS of the non-serving cell to the serving cell. Of course, the receiving time difference of the non-serving cell is less than or equal to the expected receiving time difference threshold, otherwise the terminal device does not need to measure the PRS of the non-serving cell, and does not need to perform data scheduling restrictions.

The PRS of the non-serving cell is mapped to the time-domain symbol of the serving cell, which should be determined in combination with the expected reference signal arrival time information of the non-serving cell. This means that the PRS of the non-serving cell can be mapped somewhere in the middle of the time-domain symbols of the serving cell. The time domain symbol L represents the index of the time domain symbol closest to the time domain position corresponding to the expected reference signal time difference information corresponding to the PRS of the non-serving cell. N represents the number of symbols in the time domain occupied by the PRS of the non-serving cell.

If the reception time difference of the non-serving cell is less than or equal to the length of the CP, and the time domain position occupied by the PRS of the non-serving cell on the time domain symbol L-1 is smaller than that of the CP, the access network device does not need to Perform data scheduling constraints. However, the access network device needs to perform data scheduling restrictions on the time-domain symbol L to the time-domain symbol L+N-1.

If the reception time difference of the non-serving cell is greater than the length of the CP, in addition to the time domain symbol L to the time domain symbol L+N-1, the time domain symbol L-1 and the time domain symbol L+N may also have data scheduling restrictions, specifically It should be determined in combination with the half search window defined by the expected reference signal arrival time difference information of the uncertainty of the non-serving cell.

For the situation that the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the terminal device does not want to perform PRS positioning measurement on the PRS time domain symbol overlapping with the data during the PPW of the serving cell.

Therefore, in principle there should not be any scheduling constraints due to the low priority of PRS measurements. What needs to be considered is how the terminal device determines that there is data (downlink signal or channel) during the PPW period or on the PRS time domain symbols. There should be no ambiguity regarding configuration information, eg search space, P-CSI-RS, AP-CSI-RS. The terminal equipment should know which time-domain symbols will be used for data transmission, but not for PRS positioning measurement.

For dynamically scheduled reception of a terminal device, eg, PDSCH scheduled by DCI, the terminal device knows to receive the PDSCH only after DCI decoding. If the time interval between the starting time domain position where the PDCCH (carrying DCI) is located and the starting time domain position where the PDSCH is located is too close, the terminal device cannot perform the reception of the PDSCH because the terminal device performs the reception on the corresponding time domain symbol. PRS positioning measurement. If the PDSCH sent by the access network device overlaps with the PRS of the serving cell or non-serving cell, and the start time domain position of the PDCCH is M time domain symbols or N time slots later than the start time domain position of the PDSCH, there may still be Scheduling constraints. For example, as shown in Figure 6, the initial time domain position where the PDCCH is located is M time domain symbols or N time slots before the initial time domain position where the PDSCH is located, then the access network device is at the eighth time domain position There are still data scheduling limitations.

In PPW, the DCI corresponding to the PDSCH or AP-CSI-RS scheduled in the time domain symbol occupied by the PRS should be M time domain symbols or N time domain symbols before the initial time domain position where the PDSCH or AP-CSI-RS is located time slot transmission. If the terminal device does not receive the DCI and there is no configuration data on the time domain symbol occupied by the PRS, the terminal device will receive the PRS and perform PRS measurement. This means that after M time domain symbols or N time slots, the data scheduled by the DCI (the time domain position occupied by the data overlaps with the time domain position occupied by the PRS) will be restricted. The time domain symbols occupied by the PRS include the time domain symbols occupied by the PRS of the serving cell and the time domain symbols occupied by the PRS of the non-serving cell.

Optionally, the embodiment shown in FIG. 3 further includes step 308 . Step 308 may be performed after step 304 .

308. The access network device sends the first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the access network device.

The first indication information is used to indicate that the PRS is preferentially processed or the data of the terminal device is preferentially stored within R time domain symbols after the PDCCH of the terminal device, and R is an integer greater than 0. The data of the terminal equipment includes at least one of the following: PDCCH, PDSCH, and AP-CSI-RS. Then the terminal device may preferentially process the service indicated by the first indication information within the R time domain symbols.

For example, as shown in FIG. 6 , M time-domain symbols after the PDCCH of the terminal device are used for the terminal device to parse DCI carried by the PDCCH, etc., where M is an integer greater than 0. The data of the terminal equipment occupies the M time-domain symbols. For example, URLLC data or enhanced mobile broadband data (enhanced mobile broadband data, EMBB data) of the terminal device. The M time domain symbols are also the time domain positions occupied by the PRS of the non-serving cell, that is to say, the M time domain symbols are the difference between the time domain position occupied by the data of the terminal device and the time domain position occupied by the PRS of the non-serving cell Overlap. If the priority of the data service of the terminal device is higher than the priority of the location measurement service of the terminal device (for example, the priority of the URLLC data or EMBB data of the terminal device is higher than the priority of the PRS), the access network device can send the terminal The device sends the first indication information, and the first indication information is used to indicate that the terminal device preferentially processes the data service of the terminal device within M time domain symbols after the PDCCH of the terminal device, then the terminal device processes the data service of the terminal device within M time domain symbols after the PDCCH of the terminal device Data traffic is prioritized within time domain symbols. If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device (for example, the priority of PRS is higher than the priority of URLLC data or EMBB data of the terminal device), the access network device sends the terminal device Sending first indication information, where the first indication information is used to indicate that the terminal equipment preferentially processes the positioning and measurement service of the terminal equipment within M time domain symbols after the PDCCH of the terminal equipment, then the terminal equipment is within M time domain symbols after the PDCCH of the terminal equipment Priority processing of positioning measurement services within time domain symbols. In this way, the access network device restricts the behavior of the terminal device according to the importance of the data service, and prevents the terminal device from instructing the terminal device to process the positioning measurement service first because the data service is not perceived in advance.

It should be noted that, optionally, the above step 308 may be executed on the basis of steps 303b to 305, or may not be executed on the basis of steps 303b to 305, that is, step 308 is directly executed after step 304. Applications are not limited.

In the embodiment of the present application, the terminal device determines capability information, and the capability information includes at least one of the following: scheduling restriction information, expected reception time difference threshold; the scheduling restriction information is used to indicate the data scheduling restriction of the terminal device, and the expected reception time difference threshold is The maximum receiving time difference supported by the terminal device, where the receiving time difference is the time difference between the first reference time of the serving cell and the second reference time of the non-serving cell; then, the terminal device sends the capability information. It can be seen that the terminal device can send capability information, and the capability information includes at least one of the following: scheduling restriction information, expected reception time difference threshold; the scheduling restriction information is used to indicate the data scheduling restriction of the terminal device, and the expected reception time difference threshold is the terminal The maximum receive time difference supported by the device. Therefore, it is convenient for the access network device to determine the data scheduling limit of the terminal device based on the capability information, so that the access network device can reasonably and effectively perform data scheduling of the terminal device, and improve data scheduling performance.

Before introducing the embodiments shown in Fig. 8 and Fig. 12, it should be noted that in this application, technical features with the same names in different embodiments may have different meanings, and the details should be combined with the specific embodiment where the technical features are located. understand. Of course, technical solutions that do not conflict or logically conflict between different embodiments can be combined with each other.

The definition of the receiving time difference in the embodiment shown in Figure 8 and Figure 12 is different from the definition of the receiving time difference in the embodiment shown in Figure 3 and Figure 7 above, the definition of the receiving time difference in this paper is just an example, It does not belong to the limitation of this application. In addition, in the embodiments shown in FIG. 8 and FIG. 12 , the access network devices or terminal devices determine the time-domain location with data scheduling restrictions in different ways. The determination methods shown in this document are just some examples and do not belong to the limit.

It should be noted that, in the embodiments shown in FIG. 8 and FIG. 12 , the time domain position occupied by the PRS of the cell is an estimated time domain range where the PRS of the cell may fall, specifically including the duration of the PRS of the cell. The time domain symbol and the time domain position of the search window where the PRS of the cell is located. The time domain position occupied by the PRS of the cell is determined according to the expected reference signal arrival time difference information of the cell and the uncertain expected reference signal arrival time difference information of the cell.

FIG. 8 is a schematic diagram of an embodiment of a communication method according to an embodiment of the present application. Referring to Figure 8, communication methods include:

801. The terminal device determines capability information of the terminal device.

The expected receiving time difference threshold is the maximum receiving time difference supported by the terminal device, and the receiving time difference is the time difference between the time when the terminal device receives the PRS from the serving cell and the time when the terminal device receives the PRS from the non-serving cell. The expected receiving time difference threshold is related to the capability of the terminal equipment.

For the relevant introduction of the length of the expected receiving time difference threshold, refer to the relevant introduction in step 301 in the embodiment shown in FIG. 3 , and details will not be repeated here.

The above step 801 shows that the terminal device reports the expected receiving time difference threshold to the access network device in the form of capability information. In practical applications, the expected receiving time difference threshold may also be defined by a communication protocol, or pre-configured, which is not specifically limited in this application.

Optionally, the receiving time difference is a time difference between the first initial time domain position and the second initial time domain position.

Wherein, the first starting time domain position is the starting time domain symbol of the starting subframe occupied by the PRS of the serving cell. The second starting time domain position is the starting time domain position of the starting subframe occupied by the PRS of the non-serving cell.

The first starting time domain position is determined according to the expected reference signal arrival time difference of the serving cell and/or the uncertain expected reference signal arrival time difference information of the serving cell. The second starting time domain position is determined according to the expected reference signal arrival time difference information of the non-serving cell and/or the uncertain expected reference signal arrival time difference information of the non-serving cell.

Several possible implementations of the first initial time domain position and the second initial time domain position are shown below.

1. The first initial time domain position is located at the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, and the second initial time domain position is located at the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell.

For example, as shown in FIG. 2 , the first initial time domain position is the time domain position e indicated by the expected reference signal arrival time difference information of the serving cell. For the non-serving cell 1, the second starting time-domain position is the time-domain position b indicated by the expected reference signal arrival time difference information of the non-serving cell 1 . Therefore, for non-serving cell 1, the reception time difference is equal to e-b. For the non-serving cell 2, the second initial time-domain position is the time-domain position indicated by the expected reference signal arrival time difference of the non-serving cell 2. Therefore, for the non-serving cell 2, the reception time difference is equal to e-h.

2. The first initial time domain position is located at the time corresponding to the first time length before the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, and the second initial time domain position is located at the expected reference signal arrival time corresponding to the non-serving cell The moment corresponding to the second previous duration of the time domain position corresponding to the time difference information.

Wherein, the first duration is determined according to the expected reference signal arrival time difference information of the uncertainty of the serving cell. The second duration is determined according to the expected time difference of arrival information of the non-serving cell with uncertainty.

For example, as shown in Figure 2, the length of the half search window indicated by the expected reference signal arrival time difference information of the uncertainty of the serving cell is e-d, that is, the first duration is e-d. For the non-serving cell 1, the length of the half search window indicated by the uncertain expected reference signal arrival time difference information of the non-serving cell 1 is b-a, that is, the second duration is b-a. Therefore, the first initial time domain position is d, for the second non-serving cell 1, the second initial time domain position is a, and the receiving time difference is d-a. For the non-serving cell 2, the length of the half search window indicated by the uncertain expected reference signal arrival time difference information of the non-serving cell 2 is h-g, that is, the second duration is h-g. The second starting time domain position is g, and the receiving time difference is g-d.

3. The first initial time domain position is located at the first moment, and the second initial time domain position is located at the second moment.

If the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell is before the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, the first moment is the time corresponding to the expected reference signal arrival time difference information of the serving cell The time corresponding to the first duration after the domain position, and the second time is the time corresponding to the second duration before the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell. If the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell is after the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell, the first moment is the time corresponding to the expected reference signal arrival time difference information of the serving cell The time corresponding to the first duration before the domain position, and the second time is the time corresponding to the second duration after the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell.

The first duration is determined according to the expected reference signal arrival time difference information of the uncertainty of the serving cell. The second duration is determined according to the expected time difference of arrival information of the non-serving cell with uncertainty.

For example, as shown in FIG. 2 , the length of the half search window indicated by the expected reference signal arrival time difference information of the uncertainty of the serving cell is e-f, that is, the first duration is e-f. For the non-serving cell 1, the length of the half search window indicated by the uncertain expected reference signal arrival time difference information of the non-serving cell 1 is b-a or b-c, that is, the second duration is b-a. Therefore, the first initial time domain position is f, for the second non-serving cell 1, the second initial time domain position is a, and the receiving time difference is f-a. For the non-serving cell 2, the length of the half search window indicated by the uncertain expected reference signal arrival time difference information of the non-serving cell 2 is h-i, that is, the second duration is h-i. The second starting time domain position is i, and the receiving time difference is f-i.

The reception time difference is described above using the first initial time domain position and the second initial time domain position. The reception time difference will be introduced below in another description manner.

Optionally, the receiving time difference is the time difference between the time T1 and the time T2, and the time T1 is the initial time domain position in the previous search window in the search window of the PRS of the serving cell and the search window of the PRS of the non-serving cell, Time T2 is the end time domain position in the subsequent search window of the PRS search window of the serving cell and the PRS search window of the non-serving cell.

For example, as shown in FIG. 2, for the non-serving cell 1 and the serving cell, time T1 is the start time domain position a of the search window of the non-serving cell 1, and time T2 is the end time domain position f of the search window of the serving cell. Therefore, for non-serving cell 1, the reception time difference is a-f.

Optionally, the terminal device determines the scheduling restriction information according to the concurrency capability of the terminal device. The concurrency capability refers to whether the terminal device supports concurrency of data services and positioning measurement services of the terminal device without an MG.

Specifically, if the terminal device supports concurrent data services and positioning measurement services of the terminal device without an MG, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restriction. If the terminal equipment does not support concurrency of data services and positioning measurement services of the terminal equipment in the absence of an MG, the scheduling restriction information is used to indicate that the terminal equipment has data scheduling restrictions.

For example, in a low-frequency scenario, the terminal device supports concurrent data services and positioning measurement services, that is, the terminal device can receive data and PRS at the same time, and the scheduling restriction information is used to indicate that the terminal device has no data scheduling restrictions. In a high-frequency scenario, the terminal device does not support concurrent data services and positioning measurement services, that is, the terminal device cannot receive data and PRS through the same beam, and the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions.

Optionally, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions, and some other indication functions of the scheduling restriction information are introduced below.

In a possible implementation manner, the scheduling restriction information is also used to indicate that the first time domain position is determined according to the expected reference signal arrival time difference information of the non-serving cell and the uncertain expected reference signal arrival time difference information of the non-serving cell. The terminal device at the first time domain location has data scheduling restrictions.

Optionally, the scheduling restriction information is also used to indicate that the first time domain position is determined according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the first information. For the first information, please refer to the related introduction below.

In this implementation manner, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell.

Optionally, the scheduling restriction information is also used to indicate that the first time domain position is determined according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the expected receiving time difference threshold.

In this implementation, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell and the time domain position occupied by the PRS of the serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold.

2. The scheduling restriction information is used to indicate the data scheduling restriction of the terminal device at the first time domain position.

For example, the scheduling restriction information is used to indicate that the terminal device has a data scheduling restriction at the first time domain position. Alternatively, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restriction at the first time domain position.

In a possible implementation manner, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell. Optionally, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

For example, as shown in FIG. 9A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . Optionally, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

For example, as shown in FIG. 9B , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The time domain position occupied by the PRS of the non-serving cell 1 includes an overlapping time domain position, and the overlapping time domain position is the overlapping time between the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell domain location. Optionally, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

In another possible implementation manner, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold. Optionally, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

For example, as shown in Figure 11A, the receiving time difference corresponding to non-serving cell 1 (that is, the time difference between the second initial time domain position and the first initial time domain position corresponding to non-serving cell 1) is less than or equal to the expected receiving time difference threshold. The receiving time difference corresponding to the non-serving cell 3 is greater than the expected receiving time difference threshold. Therefore, the first time domain location includes the time domain location occupied by the PRS of the non-serving cell 1 .

It should be noted that the time domain position occupied by the PRS of the non-serving cell is continuous or discontinuous with the time domain position occupied by the PRS of the serving cell, which is not limited in this application.

For example, as shown in FIG. 9A , the time domain position occupied by the PRS of the non-serving cell 1 is not continuous with the time domain position occupied by the PRS of the serving cell.

For example, as shown in Figure 9C, the time domain position occupied by the PRS of the non-serving cell 1 is continuous with the time domain position occupied by the PRS of the serving cell, while the time domain position occupied by the PRS of the non-serving cell 2 is the same as the time domain position occupied by the PRS of the serving cell. Time domain positions are discontinuous.

Optionally, the first time domain position includes N1 time domain symbols before the start time domain position of the PRS occupation of the serving cell, and/or, N2 time domain symbols after the end time domain position of the PRS occupation of the serving cell domain symbol.

The time domain position occupied by the PRS of the serving cell includes the continuous time domain symbol of the PRS of the serving cell and the time domain positions occupied by the two half search windows corresponding to the PRS of the serving cell.

The N time domain symbols are the time domain positions occupied by the PRS of the non-serving cell of the terminal device before the initial time domain position occupied by the PRS of the serving cell. The N2 time-domain symbols are the time-domain positions occupied by the PRS of the non-serving cell of the terminal device after the end time-domain position occupied by the PRS of the serving cell. N1 and N2 are integers greater than or equal to 0.

It should be noted that when both N1 and N2 are equal to 0, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restriction. When N1 is greater than 0 and N2 is equal to 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N1 time domain symbols. When N1 is equal to 0 and N2 is greater than 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N2 time domain symbols. When both N1 and N2 are greater than 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N1 time domain symbols and the N2 time domain symbols.

It should be noted that the duration of the time domain position occupied by the PRS of the non-serving cell before the initial time domain position occupied by the PRS of the serving cell may be duration 1. The duration of the time domain position of the PRS occupation of the non-serving cell after the end time domain position of the PRS occupation of the serving cell may be duration 2 . Units of duration 1 and duration 2 may be seconds, milliseconds, or time domain symbols, which are not limited in this application. In the above, the time domain position occupied by the PRS of the non-serving cell before the starting time domain position occupied by the PRS of the serving cell is N1 time domain symbols, and the time domain position of the non-serving cell located after the end time domain position of the PRS occupation of the serving cell is The time domain positions occupied by the PRS are N2 time domain symbols as an example to introduce the technical solution of the present application.

For example, as shown in FIG. 9A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The N1 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 1, and the N2 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 2.

For example, as shown in FIG. 9B , the first time domain position includes time domain positions other than overlapping time domain positions among the time domain positions occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The N1 time domain symbols are time domain positions other than overlapping time domain positions among the time domain positions occupied by the PRS of the non-serving cell 1, and the N2 time domain symbols are the time domain occupied by the PRS of the non-serving cell 2 Location.

For example, as shown in FIG. 9D, the first time domain position includes N1 time domain symbols before the start time domain position occupied by the PRS of the serving cell, and the N1 time domain symbols are occupied by the PRS of the non-serving cell 1. time domain location.

For example, as shown in FIG. 9E, the first time domain position includes N2 time domain symbols located after the end time domain position occupied by the PRS of the serving cell, and the N2 time domain symbols are occupied by the PRS of the non-serving cell 2. time domain location.

It should be noted that, optionally, the N1 time domain symbols are continuous or discontinuous with the time domain positions occupied by the PRS of the serving cell, and the N2 time domain symbols are continuous or discontinuous with the time domain positions occupied by the PRS of the serving cell.

For example, as shown in FIG. 9A , the N1 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 1, and the N1 time domain symbols are discontinuous with the time domain positions occupied by the PRS of the serving cell. The N2 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 2, and the N2 time domain symbols are discontinuous with the time domain positions occupied by the PRS of the serving cell.

For example, as shown in FIG. 9C , the N1 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 1, and the N1 time domain symbols are continuous with the time domain positions occupied by the PRS of the serving cell. The N2 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell 2, and the N2 time domain symbols are discontinuous with the time domain positions occupied by the PRS of the serving cell.

It should be noted that if the length of the expected receiving time difference threshold is not limited, the terminal device can perform positioning measurement on the PRS of the non-serving cell on the N1 time domain symbols and N2 time domain symbols regardless of the values of N1 and N2.

Some possible indication manners of the scheduling restriction information are introduced below in conjunction with the first time domain position.

In a possible implementation manner, if the first time domain position is a continuous time domain position, the scheduling restriction information is used to indicate the starting time domain symbol of the first time domain position and the number of time domain symbols included in the first time domain position , to indicate that there are data scheduling constraints on these first time domain locations.

For example, as shown in FIG. 9C , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1, the time domain position occupied by the PRS of the non-serving cell 2, and the time domain position occupied by the PRS of the serving cell. The time domain positions of these three parts are continuous, and the terminal device has data scheduling restrictions at the first time domain position, and the scheduling restriction information may indicate the starting time domain position and the first time domain position in the first time domain position Included time domain notation.

In another possible implementation manner, if the first time domain positions are discontinuous time domain positions, the scheduling restriction information may be a bitmap. The bits in the bitmap correspond one-to-one to the time-domain symbols included in the subframe or slot. The bits in the bitmap are respectively used to indicate data scheduling restrictions of corresponding time domain symbols. The first time domain location falls within the subframe or the time slot.

For example, as shown in FIG. 9A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1, the time domain position occupied by the PRS of the non-serving cell 2, and the time domain position occupied by the PRS of the serving cell. The first time domain position falls within a time slot, and the time domain positions occupied by the PRS of the non-serving cell 1 include time domain symbol 1 to time domain symbol 3 of the time slot. The time domain positions occupied by the PRS of the serving cell include time domain symbol 6 to time domain symbol 9 of the time slot. The time domain positions occupied by the PRS of the non-serving cell 2 include time domain symbol 11 to time domain symbol 12 of the time slot. Therefore, the bitmap is 0111001111011, a bit with a value of 1 in the bitmap means that there is a data scheduling restriction, and a bit with a value of 0 means that there is no data scheduling restriction. That is to say, the blank part in FIG. 9A has no data scheduling restriction.

Several determination methods for the terminal device to determine the first time domain position are introduced below.

Determination mode 1. The terminal device determines the first time domain position according to the expected time difference of arrival information of the non-serving cell and the uncertain expected time difference of arrival information of the non-serving cell.

The first time domain location includes a time domain location occupied by a PRS of a non-serving cell.

For example, as shown in Figure 9A, the terminal device determines the time domain position occupied by the PRS of the non-serving cell 1 through the expected reference signal arrival time difference information of the non-serving cell 1 and the uncertain expected reference signal arrival time difference information of the non-serving cell 1 . The terminal device determines the time domain position occupied by the PRS of the non-serving cell 2 through the expected time difference of arrival information of the non-serving cell 2 and the uncertain expected time difference of arrival information of the non-serving cell 2 . Therefore, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 .

For example, as shown in FIG. 9B , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The time domain position occupied by the PRS of the non-serving cell 1 includes an overlapping time domain position, and the overlapping time domain position is the overlapping time between the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell domain location.

It should be noted that if the length of the time-domain position occupied by the PRS of the non-serving cell is in the time-domain symbol, and the length is not an integer multiple of the time-domain symbol, the terminal device can The length of the domain position is rounded up, and then the first time domain position is determined. For example, as shown in Figure 9B, the length of the time domain position occupied by the PRS of the non-serving cell 1 is 14.5 time domain symbols, and the length of the time domain position occupied by the PRS of the non-serving cell 2 is 13 time domain symbols, then The terminal device may determine that the first time domain position includes 15 time domain symbols before the starting time domain position occupied by the PRS of the serving cell (the 15 time domain symbols include the time domain occupied by the PRS of the non-serving cell 1 position) and 13 time domain symbols after the end time domain position occupied by the PRS of the serving cell.

In this implementation, optionally, the terminal device determines the first time domain position according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the first information.

For example, as shown in Fig. 10A, the terminal device bases on the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the expected reference signal, the time slot offset of the resource set, the number of symbols Offset, slot offset, and frame offset may determine the time domain location of the first portion in FIG. 10A. The terminal device may determine the position of the second part in the time domain according to the number of repetitions of sending the PRS and the time interval between repeated sendings of the PRS of the non-serving cell. The terminal device determines, according to the silent pattern of the PRS of the non-serving cell, that the silent pattern at the position of the transmission cycle of the PRS is to send, not to send, or to send. That is, the terminal device can determine that the non-serving cell does not transmit PRS at the third part of the time domain position according to the PRS transmission period of the non-serving cell and the number of continuous time domain symbols of the PRS, and the non-serving cell at the fourth part of the time domain position The cell sends a PRS. Therefore, it can be known that the first time-domain position includes a first part of time-domain positions, a second part of time-domain positions and a fourth part of time-domain positions.

Optionally, the terminal device determines the first time domain position according to the expected reference signal arrival time difference information of the non-serving cell and the uncertain expected reference signal arrival time difference information of the non-serving cell, including:

According to the expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the non-serving cell uncertainty, the expected reference signal arrival time difference information of the serving cell, and the expected reference signal arrival time difference information of the serving cell The time difference information determines a first time domain location.

Specifically, the terminal device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell and the uncertain expected time difference of arrival information of the non-serving cell. The terminal device determines the time domain position occupied by the PRS of the serving cell according to the expected reference signal arrival time difference information of the serving cell and the uncertain expected reference signal arrival time difference information of the serving cell. Then, the terminal device takes the time domain position occupied by the PRS of the non-serving cell and the time domain position occupied by the PRS of the serving cell as the first time domain position.

In this implementation manner, the first time domain position includes a time domain position occupied by the PRS of the serving cell and a time domain position occupied by the PRS of the non-serving cell.

For example, as shown in FIG. 9D , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell.

Determination mode 2. The terminal device determines the first time domain position according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the expected receiving time difference threshold.

The first time domain position includes a time domain position occupied by a PRS of a non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold.

Specifically, the terminal device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell and the uncertain expected time difference of arrival information of the non-serving cell. Then, the terminal device judges whether the receiving time difference corresponding to each non-serving cell is less than or equal to the expected receiving time difference threshold, and if so, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell. If not, the terminal device determines the non-serving cell whose receiving time difference is greater than the expected receiving time difference threshold, and excludes the time domain positions occupied by the PRS of the non-serving cell whose corresponding receiving time difference is greater than the expected receiving time difference threshold. time domain position, to obtain the first time domain position.

For example, as shown in FIG. 9A, if the receiving time difference corresponding to non-serving cell 1 is greater than the expected receiving time difference threshold, and the receiving time difference corresponding to non-serving cell 2 is smaller than the expected receiving time difference threshold, the terminal device may determine that the first time domain location includes the non-serving time difference threshold. The time domain position occupied by the PRS of cell 2.

In a possible implementation manner, the terminal device determines the first time domain according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, the first information, and the expected receiving time difference threshold Location. For the first information, please refer to the aforementioned introduction.

Specifically, the terminal device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell and the first information. For the process of the terminal device determining the time-domain position occupied by the PRS of the non-serving cell, please refer to the relevant introduction mentioned above. Then, the terminal device determines the first time domain position according to the time domain position occupied by the PRS of the non-serving cell and the expected receiving time difference threshold. Specifically, the terminal device takes the time domain position occupied by the PRS of the non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold among the time domain positions occupied by the PRS of the non-serving cell as the first time domain position.

It should be noted that if there is overlap between the time domain position occupied by the PRS of the serving cell and the time domain position occupied by the PRS of the non-serving cell, the first time domain position includes the time domain position occupied by the PRS of the serving cell and the time domain position occupied by the PRS of the non-serving cell. The overlapping time domain position between the time domain positions occupied by the serving cell; or, the first time domain position does not include the overlapping time domain position between the time domain position occupied by the PRS of the serving cell and the time domain position occupied by the non-serving cell , the specific application is not limited.

Optionally, according to the expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the non-serving cell uncertainty, the expected reference signal arrival time difference information of the serving cell, and the uncertainty of the serving cell The expected reference signal arrival time difference information and the expected receiving time difference threshold determine the first time domain position.

Specifically, the terminal device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell and the first information. Then, the terminal device determines the time domain position occupied by the PRS of the non-serving cell whose receiving time difference is less than or equal to the expected receiving time difference threshold according to the time domain position occupied by the PRS of the non-serving cell and the expected receiving time difference threshold. The terminal device determines the time domain position occupied by the PRS of the serving cell according to the expected reference signal arrival time difference information of the serving cell and the uncertain expected reference signal arrival time difference information of the serving cell. The terminal device takes the time domain position occupied by the PRS of the non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold and the time domain position occupied by the PRS of the serving cell as the first time domain position.

The first time domain position includes the time domain position occupied by the PRS of the non-serving cell and the time domain position occupied by the PRS of the serving cell corresponding to the receiving time difference less than or equal to the expected receiving time difference threshold.

For example, as shown in FIG. 9A, if the receiving time difference corresponding to non-serving cell 1 is greater than the expected receiving time difference threshold, and the receiving time difference corresponding to non-serving cell 2 is smaller than the expected receiving time difference threshold, the terminal device may determine that the first time domain location includes the non-serving time difference threshold. The time domain position occupied by the PRS of cell 2 and the time domain position occupied by the PR of the serving cell.

In a possible implementation, the terminal device uses the expected reference signal difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, the expected reference signal difference of arrival information of the serving cell, and the The uncertain expected reference signal arrival time difference information, the first information and the expected receiving time difference threshold determine the first time domain position. For the first information, please refer to the relevant introduction above.

Specifically, the terminal device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell and the first information. The terminal device determines, according to the expected receiving time difference threshold, the time domain positions occupied by the PRS of the non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold. The terminal device determines the time domain position occupied by the PRS of the serving cell according to the expected reference signal arrival time difference information of the serving cell and the uncertain expected reference signal arrival time difference information of the serving cell. The terminal device takes the time domain position occupied by the PRS of the non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold and the time domain position occupied by the PRS of the serving cell as the first time domain position.

Optionally, the expected receiving time difference threshold is used to determine the second time domain position.

Wherein, the second time domain position includes a third time domain position located before and continuous to the start time domain position of the PRS occupation of the serving cell, and a third time domain position located after the end time domain position of the PRS occupation of the serving cell And a fourth time domain position continuous with the end time domain position. The duration of the third time domain position and the duration of the fourth time domain position are respectively equal to the duration of the expected receiving time difference threshold.

For example, as shown in FIG. 10B , the third time domain position before and continuous to the start time domain position of the PRS occupation of the serving cell and the end time domain position of the PRS occupation of the serving cell are after and adjacent to the third time domain position. At the fourth consecutive time domain position at the end time domain position, the terminal device has data scheduling restrictions.

802. The terminal device sends capability information of the terminal device.

On the other hand, after the location management device receives the capability information, the location management device can combine the capability information to determine which non-serving cell PRS the terminal device can perform location measurement on, and combine the capability information to configure the PRS resources of the non-serving cell.

For example, as shown in FIG. 9A , the capability information includes scheduling restriction information and an expected reception time difference threshold. The scheduling restriction information is used to indicate that there is data scheduling restriction on the first time domain position, and the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The positioning management device determines that the time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position corresponding to the serving cell is greater than the expected receiving time difference threshold. The positioning management device determines that the time difference between the second initial time domain position corresponding to the non-serving cell 2 and the first initial time domain position corresponding to the serving cell is less than or equal to the expected receiving time difference threshold. Therefore, the positioning management device determines that the terminal device cannot perform positioning measurement on the PRS of the non-serving cell 1 , but can perform positioning measurement on the PRS of the non-serving cell 2 .

Then the above step 804 specifically includes step 8041 and step 8042 .

8041. The access network device determines the first time domain position according to the expected reference signal arrival time difference information of the non-serving cell and the uncertain expected reference signal arrival time difference information of the non-serving cell.

For example, as shown in FIG. 9A, the access network device may determine the PRS occupancy of the non-serving cell 1 according to the expected reference signal arrival time difference information of the non-serving cell 1 and the uncertain expected reference signal arrival time difference information of the non-serving cell 1. time domain location. The access network device may determine the time domain position occupied by the PRS of the non-serving cell 2 according to the expected reference signal arrival time difference information of the non-serving cell 2 and the uncertain expected reference signal arrival time difference information of the non-serving cell 2 .

Optionally, the scheduling restriction information is also used to indicate that the first time domain position is determined according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the first information. The terminal device at the first time domain location has data scheduling restrictions.

In this implementation manner, optionally, the embodiment shown in FIG. 8 further includes step 803b.

803b. The access network device acquires the first information.

For the first information, please refer to the relevant introduction above.

If the terminal device at the first time domain position has data scheduling restrictions, and the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device at the first time domain position have data scheduling constraints; or,

If the terminal device at the first time domain position has data scheduling restrictions, and the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device at the first time domain position There are no data scheduling restrictions.

For example, as mentioned above about the priority processing capability supported by the terminal device, if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device (that is, the priority of the PRS is higher than that of other data), the access network The device determines that the terminal device has a data scheduling restriction at the first time domain location.

For example, as mentioned above about the priority processing capability supported by the terminal device, if the priority of the positioning measurement service of the terminal device is lower than that of the data service of the terminal device (that is, the priority of the PRS is lower than that of other data), the access network The device determines that the terminal device has no data scheduling restriction at the first time domain location.

For example, as shown in FIG. 9A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position. If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device has no data scheduling restriction at the first time domain position.

For example, as shown in FIG. 9B , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1, the time domain position occupied by the PRS of the non-serving cell 2, and the time domain position occupied by the PRS of the serving cell. If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position. If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device has no data scheduling restriction at the first time domain position.

For example, as shown in FIG. 11A , the receiving time difference corresponding to non-serving cell 1 is less than or equal to the expected receiving time difference threshold, and the receiving time difference corresponding to non-serving cell 3 is greater than the expected receiving time difference threshold. Therefore, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell. If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position. If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device has no data scheduling restriction at the first time domain position.

In a possible implementation manner, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell; optionally, the first time domain position further includes a time domain position occupied by a PRS of a serving cell.

If the capability information also includes the expected receiving time difference threshold, the above step 8042 specifically includes:

1. If the time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell is less than or equal to the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is higher than that of the data of the terminal device priority of the service, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position; or,

For example, as shown in FIG. 9D , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 . The second initial time domain position corresponding to the non-serving cell 1 is the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell 1 . The first initial time domain position corresponding to the serving cell is the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell. If the time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell 1 is less than or equal to the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is higher than that of the data service of the terminal device priority, the access network device determines that the terminal device has data scheduling restrictions at the time domain position occupied by the PRS of non-serving cell 1.

For example, as shown in FIG. 9E , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 2 . The second initial time domain position corresponding to the non-serving cell 2 is the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell 2 . The first initial time domain position corresponding to the serving cell is the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell. If the time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell 2 is less than or equal to the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is higher than that of the data service of the terminal device priority, the access network device determines that the data of the terminal device at the time domain position occupied by the PRS of the non-serving cell 2 has scheduling restrictions.

2. If the time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell is less than or equal to the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is lower than that of the data of the terminal device priority of the service, the access network device determines that there is no data scheduling restriction on the terminal device at the first time domain position; or,

For example, as shown in FIG. 9D , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 . The second initial time domain position corresponding to the non-serving cell 1 is the time domain position corresponding to the expected reference signal arrival time difference information of the non-serving cell 1 . The first initial time domain position corresponding to the serving cell is the time domain position corresponding to the expected reference signal arrival time difference information of the serving cell. If the time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell 1 is less than or equal to the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is lower than that of the data service of the terminal device priority, the access network device determines that there is no data scheduling restriction on the terminal device at the time domain position occupied by the PRS of non-serving cell 1.

3. If the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is greater than the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is higher than that of the data service of the terminal device priority, the access network device determines that the terminal device has data scheduling restrictions in the first target time domain position; or,

Wherein, the first target time domain position includes a time domain symbol occupied by the PRS of the first cell. The first cell is a non-serving cell whose time difference between the corresponding second initial time domain position and the first initial time domain position is less than or equal to the expected receiving time difference threshold.

For example, as shown in FIG. 11A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 3 and the first initial time domain position is greater than the expected receiving time difference threshold, so the access network device will not perform positioning measurement on the PRS of the non-serving cell 3. There is no data scheduling restriction on the terminal equipment at the time domain position occupied by the PRS of the serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position is smaller than the expected receiving time difference threshold. Therefore, the first cell includes the non-serving cell 1, and if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device is located in the time domain position occupied by the PRS of the non-serving cell 1 End devices have no data scheduling restrictions.

For example, as shown in FIG. 11B , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 2 and the time domain position occupied by the PRS of the non-serving cell 4 . The time difference between the second initial time domain position corresponding to the non-serving cell 4 and the first initial time domain position is greater than the expected receiving time difference threshold, so the access network device will not perform positioning measurement on the PRS of the non-serving cell 4 . Therefore, there is no data scheduling for the terminal equipment at the time domain position occupied by the PRS of the non-serving cell 4 . The time difference between the second initial time domain position corresponding to the non-serving cell 2 and the first initial time domain position is smaller than the expected receiving time difference threshold. Therefore, the first cell includes the non-serving cell 2, and if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device is located in the time domain position occupied by the PRS of the non-serving cell 2 End devices have no data scheduling restrictions.

It should be noted that the above-mentioned FIG. 11A and FIG. 11B are just examples. In fact, the time domain positions occupied by PRSs of different non-serving cells may or may not overlap. , depending on the specific location of the time domain locations occupied by the PRSs of different non-serving cells, which is not limited in this application.

4. If the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is greater than the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is lower than that of the data service of the terminal device priority, the access network device determines that there is no data scheduling restriction on the terminal device in the first target time domain position; or,

Wherein, the first target time domain position includes a time domain symbol occupied by the PRS of the first cell. The first cell is a non-serving cell whose corresponding time difference between the second initial time domain position and the first initial time domain position is less than or equal to the expected receiving time difference threshold.

For example, as shown in FIG. 11A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 3 and the first initial time domain position is greater than the expected receiving time difference threshold, so the terminal device will not perform positioning measurement on the PRS of the non-serving cell 3 . Therefore, there is no data scheduling restriction for the terminal equipment at the time domain position occupied by the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position is smaller than the expected receiving time difference threshold. Therefore, the first cell includes non-serving cell 1. If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device will be at the time domain position occupied by the PRS of the non-serving cell 1. End devices have data scheduling constraints.

2. The capability information includes scheduling restriction information, and the scheduling restriction information is used to indicate the data scheduling restriction of the terminal device at the position in the first time domain.

Optionally, the first time domain position includes N1 time domain symbols before the time domain position occupied by the PRS of the serving cell and N2 time domain symbols after the time domain position occupied by the PRS of the serving cell. The N1 time domain symbols are the time domain positions occupied by the PRS of the non-serving cell of the terminal device before the initial time domain position occupied by the PRS of the serving cell. The N2 time-domain symbols are the time-domain positions occupied by the PRS of the non-serving cell of the terminal device after the end time-domain position occupied by the PRS of the serving cell. N1 and N2 are integers greater than or equal to 0.

Optionally, the first time domain position further includes a time domain position occupied by the PRS of the serving cell.

In a possible implementation manner, the scheduling restriction information is used to indicate that the terminal device has no data scheduling restriction at the first time domain position. In this implementation manner, the values of N1 and N2 are both 0, indicating that the terminal device has no data scheduling restriction.

In another possible implementation manner, the scheduling restriction information is used to indicate that the terminal device has a data scheduling restriction at the first time domain position. For example, when N1 is greater than 0 and N2 is equal to 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N1 time domain symbols. When N1 is equal to 0 and N2 is greater than 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N2 time domain symbols. When both N1 and N2 are greater than 0, the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions on the N1 time domain symbols and the N2 time domain symbols.

Case 1: The first time domain position is determined by the terminal device according to the expected time difference of arrival information of the non-serving cell and the uncertain expected time difference of arrival information of the non-serving cell.

In this implementation manner, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell.

Optionally, the first time domain position is determined by the terminal device according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the first information. For the first information, please refer to the relevant introduction above.

Optionally, the first time domain position is the terminal device's expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the uncertainty of the non-serving cell, the first information, and the expected reference signal arrival time of the serving cell. The time difference information and the uncertainty of the serving cell are determined by the expected reference signal arrival time difference information;

Alternatively, the first time domain position is based on the expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the non-serving cell uncertainty, the expected reference signal arrival time difference information of the serving cell, and the The uncertainty of the expected reference signal arrival time difference information is determined.

In this implementation manner, the first time domain position includes the time domain position occupied by the PRS of the serving cell and the time domain position occupied by the PRS of the non-serving cell.

In a possible implementation manner, the above step 804 specifically includes:

In another possible implementation, if the capability information also includes the expected receiving time difference threshold, the above step 804 specifically includes:

For example, as shown in FIG. 9A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . The time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell 1 is less than or equal to the expected receiving time difference threshold. The time difference between the first initial time domain position and the second initial time domain position corresponding to the non-serving cell 2 is less than or equal to the expected receiving time difference threshold. Therefore, if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines the time domain position occupied by the PRS of the non-serving cell 1 and the time domain occupied by the PRS of the non-serving cell 2 Terminal devices on domain locations have data scheduling restrictions.

3. If the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is greater than the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is higher than that of the data service of the terminal device priority, the access network device determines that the terminal device has data scheduling restrictions at the first target time domain position; or,

For example, as shown in FIG. 11B , the first time domain position includes the time domain positions occupied by the PRSs of the non-serving cell 2 and the non-serving cell 4 . The time difference between the second initial time domain position corresponding to the non-serving cell 2 and the first initial time domain position is less than or equal to the expected receiving time difference. The time difference between the second initial time domain position corresponding to the non-serving cell 4 and the first initial time domain position is greater than the expected receiving time difference threshold. Therefore, the access network device will not perform positioning measurement on the PRS of the non-serving cell 4 . Thus, the first cell comprises the non-serving cell 2 . If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the time domain position occupied by the PRS of the non-serving cell 2 .

For example, as shown in FIG. 11C , the first time domain position includes the time domain positions occupied by the PRSs of non-serving cell 1 to non-serving cell 4 . The time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position is less than or equal to the expected receiving time difference. The time difference between the second initial time domain position corresponding to the non-serving cell 3 and the first initial time domain position is greater than the expected receiving time difference threshold, so the access network device will not perform positioning measurement on the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 2 and the first initial time domain position is less than or equal to the expected receiving time difference threshold, and the second initial time domain position corresponding to the non-serving cell 4 is the same as the first initial time domain position The time difference between domain locations is less than or equal to the expected reception time difference threshold. Therefore, the first cell includes non-serving cell 1 , non-serving cell 2 and non-serving cell 4 . If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines the time domain position occupied by the PRS of non-serving cell 1, non-serving cell 2 and non-serving cell 4 The device has data scheduling limitations.

4. If the time difference between the second initial time domain position corresponding to the non-serving cell and the first initial time domain position is greater than the expected receiving time difference threshold, and the priority of the positioning measurement service of the terminal device is lower than that of the data service of the terminal device priority, the access network device determines that there is no data scheduling restriction on the terminal device at the first target time domain position; or,

For example, as shown in FIG. 11A , the first time domain position includes time domain positions occupied by PRSs of non-serving cell 1 and non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position is less than or equal to the expected receiving time difference. The time difference between the second initial time domain position corresponding to the non-serving cell 3 and the first initial time domain position is greater than the expected receiving time difference threshold. Therefore, the access network device will not perform positioning measurement on the PRS of the non-serving cell 3 . Thus, the first cell comprises the non-serving cell 1 . If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device has no data scheduling restriction at the time domain position occupied by the PRS of the non-serving cell 1 .

Case 2: The first time domain position is determined by the terminal device according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, and the expected receiving time difference threshold.

In this case, the first time domain position includes a time domain position occupied by a PRS of a non-serving cell whose corresponding reception time difference is less than or equal to the expected reception time difference threshold.

Optionally, the first time-domain position is based on the expected reference signal arrival time difference information of the non-serving cell, the expected reference signal arrival time difference information of the non-serving cell uncertainty, the expected reception time difference threshold, and the expected reference signal arrival time difference of the serving cell. The arrival time difference information and the expected reference signal arrival time difference information of the uncertainty of the serving cell are determined. In this implementation, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell whose corresponding receiving time difference is less than or equal to the expected receiving time difference threshold and the time domain position occupied by the PRS of the serving cell.

In a possible implementation manner, the above step 804 specifically includes:

For example, the first time domain position includes the time domain position occupied by the PRS of the serving cell and the time domain position occupied by the PRS of the non-serving cell (including non-serving cell 1 and non-serving cell 2 ). If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position.

It should be noted that, optionally, in the implementation manner in which the first time domain position includes the time domain position occupied by the PRS of the non-serving cell, if the first time domain position includes the time domain position occupied by the PRS of the non-serving cell If there is an overlapping time domain position between the time domain positions occupied by the PRS of the cell, the access network device can determine the data of the terminal device at the time domain positions other than the overlapping time domain positions in the time domain positions occupied by the PRS of the non-serving cell Scheduling constraints. There are no data scheduling restrictions for terminal devices at overlapping time domain locations. That is to say, the terminal device can receive the PRS of the serving cell and the PRS of the non-serving cell at the overlapping time domain position, and perform corresponding positioning measurement.

For example, as shown in FIG. 9B , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 2 . There is an overlapping time domain position between the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the serving cell. Therefore, the access network device can determine the time domain positions excluding overlapping time domain positions among the time domain positions occupied by the PRS of the non-serving cell 1 and the data scheduling restriction of the terminal device at the time domain positions occupied by the PRS of the non-serving cell 2 .

3. The capability information includes the expected receiving time difference threshold. Optionally, the foregoing step 804 specifically includes step 8043 and step 8044 .

8043. The access network device determines the first time domain position according to the expected reference signal arrival time difference information of the non-serving cell, the uncertain expected reference signal arrival time difference information of the non-serving cell, and the expected reception time difference threshold.

The first time domain position includes the time domain position occupied by the PRS of the non-serving cell whose receiving time difference is less than or equal to the expected receiving time difference threshold and the time domain position occupied by the PRS of the serving cell.

For example, as shown in FIG. 11A , the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 and the time domain position occupied by the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 3 and the first initial time domain position is greater than the expected receiving time difference threshold, so the terminal device will not perform positioning measurement on the PRS of the non-serving cell 3 . The time difference between the second initial time domain position corresponding to the non-serving cell 1 and the first initial time domain position is less than or equal to the expected receiving time difference threshold. Therefore, the access network device may determine that the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 1 .

Before the above step 804, the terminal device may acquire the expected reference signal arrival time difference information of the non-serving cell and the uncertain expected reference signal arrival time difference information of the non-serving cell in the manner shown in the above step 803a.

Optionally, the above step 8043 specifically includes:

The access network device determines the first time domain position according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, the first information, and the expected receiving time difference threshold.

Specifically, the access network device determines the time domain position occupied by the PRS of the non-serving cell according to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell and the first information. Then, the access network device determines the first time domain position from the time domain position occupied by the PRS of the non-serving cell according to the expected receiving time difference threshold.

For example, as shown in Figure 11A, the access network device determines the PRS occupancy of the non-serving cell 1 according to the expected reference signal arrival time difference information of the non-serving cell, the uncertain expected reference signal arrival time difference information of the non-serving cell, and the first information and the time domain position occupied by the PRS of the non-serving cell 3 . The access network device determines that: the time difference between the second initial time domain position corresponding to non-serving cell 1 and the first initial time domain position is less than or equal to the expected receiving time difference threshold, and the second initial time domain position corresponding to non-serving cell 3 The time difference between the location and the first initial time domain location is greater than the expected reception time difference threshold. Therefore, the access network device may determine that the first time domain location includes the time domain location occupied by the PRS of the non-serving cell 1 .

Optionally, the above step 8043 specifically includes:

According to the expected time difference of arrival information of the non-serving cell, the uncertain expected time difference of arrival information of the non-serving cell, the expected reception time difference threshold, the expected time difference of arrival information of the serving cell, and the non-deterministic The deterministic expected reference signal arrival time difference information determines the first time domain location.

In this implementation, the first time domain position includes the time domain position occupied by the PRS of the non-serving cell and the time domain position occupied by the PRS of the serving cell whose receiving time difference is less than or equal to the expected receiving time difference threshold.

For example, as shown in Figure 11B, the access network device determines the PRS occupancy of the non-serving cell 2 according to the expected reference signal arrival time difference information of the non-serving cell, the uncertain expected reference signal arrival time difference information of the non-serving cell, and the first information and the time domain position occupied by the PRS of the non-serving cell 4. The access network device determines that: the time difference between the second initial time domain position corresponding to the non-serving cell 2 and the first initial time domain position is less than or equal to the expected receiving time difference threshold, and the second initial time domain position corresponding to the non-serving cell 4 The time difference between the location and the first initial time domain location is greater than the expected reception time difference threshold. The access network device determines the time domain position occupied by the PRS of the serving cell according to the expected reference signal arrival time difference information of the serving cell and the uncertain expected reference signal arrival time difference information of the serving cell. Therefore, the access network device may determine the first time domain position, and the first time domain position includes the time domain position occupied by the PRS of the non-serving cell 2 and the time domain position occupied by the PRS of the serving cell.

8044. The terminal device determines the data scheduling restriction of the terminal device at the first time domain position.

If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the first time domain position; or,

If the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that the terminal device has no data scheduling restriction at the first time domain position. For specific related examples, please refer to the aforementioned related introductions.

Fourth, the capability information includes an expected receiving time difference threshold, and the expected receiving time difference threshold is used to determine the second time domain position.

The second time domain position includes a third time domain position located before the start time domain position of the PRS occupation of the serving cell and continuous with the start time domain position, and a third time domain position located after the end time domain position of the PRS occupation of the serving cell and The fourth time domain position consecutive to the end time domain position, the duration of the third time domain position and the duration of the fourth time domain position are respectively equal to the duration of the expected receiving time difference threshold. The terminal device has data scheduling constraints at the second time domain location.

Optionally, the capability information further includes scheduling restriction information, and the scheduling restriction information is used to indicate that the terminal device has data scheduling restrictions; or, the scheduling restriction information is used to indicate that the second time domain position is determined according to the expected receiving time difference threshold.

Based on this, optionally, the above step 804 specifically includes step 8045 and step 8046:

8045. The access network device determines the second time domain position according to the expected receiving time difference threshold.

For the position of the second time domain, please refer to the relevant introduction above.

8046. The access network device determines the data scheduling restriction of the terminal device at the second time domain location.

Specifically, if the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the second time domain position. Alternatively, if the priority of the positioning measurement service of the terminal device is lower than the priority of the data service of the terminal device, the access network device determines that there is no data scheduling restriction for the terminal device at the second time domain position.

For example, as shown in FIG. 10B , the third time domain position before and continuous to the start time domain position of the PRS occupation of the serving cell and the end time domain position of the PRS occupation of the serving cell are after and adjacent to the third time domain position. At the fourth consecutive time domain position at the end time domain position, the terminal device has data scheduling restrictions. If the priority of the positioning measurement service of the terminal device is higher than the priority of the data service of the terminal device, the access network device determines that the terminal device has data scheduling restrictions at the third time domain position and the fourth time domain position.

It can be seen that, in the technical solution of the present application, the access network device determines the data scheduling restriction of the terminal device according to the capability information of the terminal device and the service priority of the terminal device. In this way, the access network equipment can reasonably and effectively perform data scheduling of the terminal equipment, and improve data scheduling performance.

Optionally, the embodiment shown in FIG. 8 further includes steps 805 to 807. Step 805 to step 807 may be performed after step 804 .

805. The access network device sends the PDCCH to the terminal device. Correspondingly, the terminal device receives the PDCCH from the access network device.

Specifically, the access network device schedules the PDCCH of the terminal device.

Optionally, the embodiment shown in FIG. 8 further includes step 805a, and step 805a may be performed before step 805.

805a. The terminal device sends the second information to the access network device. Correspondingly, the access network device receives the second information from the terminal device.

The second information is used to indicate that the terminal equipment needs M time domain symbols or N time slots after the PDCCH of the terminal equipment, where M is an integer greater than or equal to 0, and N is an integer greater than or equal to 0.

It should be noted that, in the communication protocol, the value of M may be at least one of the above 7, 14, 28, 42, and 56. The value of N may be at least one of the above 1, 2, 3, 4. For example, the value of M is {7, 14, 28, 42}. The value of N is {1,2,3}. Alternatively, the value of M is {7, 14, 28, 42, 56}, and the value of N is {1, 2, 3, 4}.

Optionally, the M time-domain symbols or N time slots are used for the terminal device to analyze the DCI carried in the PDCCH and determine the time for the behavior of the terminal device on a certain time-domain symbol.
