Description

A method and device for configuring a measurement interval

technical field

The present application relates to the technical field of communications, and in particular to a method and device for configuring a measurement interval.

Background technique

With the rapid development of communication technology, high-precision positioning has gradually been identified as an important research project in the fifth generation mobile networks (5th generation mobile networks or 5th generation wireless systems, 5G). Among them, the positioning scenarios in the new radio (new radio, NR) communication system may include: enhanced mobile broadband (enhanced mobile broadband, eMBB) outdoors, eMBB indoors, ultra-reliable and low latency communications (URLLC) And massive machine type of communication (massive machine type of communication, mMTC)/Internet of things (internet of things, IOT), etc. At the same time, the communication system is also required to have the characteristics of high security, scalability, high availability, and precision assurance in high-speed applications. As positioning requirements and positioning scenarios become more and more extensive, the requirements for positioning accuracy are also getting higher and higher.

In order to measure the reference signal on a target frequency point, the terminal device needs to tune the radio frequency from the serving cell to the target frequency point, resulting in the interruption of data transmission in the serving cell, so the network device needs to configure the measurement gap (Measurement Gap, MG), within the configured MG duration, no data transmission is performed between the network device and the terminal device, so as to facilitate the measurement of reference signals; MG configuration parameters include: MG length (also called MG duration, that is, the duration of MG Time, that is, the length of time when the data transmission of the serving cell is interrupted), the MG cycle (that is, the time interval for the interruption of data transmission in the serving cell), and the MG time domain offset (offset, used to determine the time starting point of the MG), etc., the MG indicates You can refer to Figure 1. MG can appear periodically according to the configuration. Each occurrence is called an MG occasion (opportunity). During the duration of each MG occasion, no data transmission is performed between the network device and the terminal device.

During the positioning process, the measurement of the reference signal may be based on the MG. When the terminal device needs to measure the positioning reference signal (Positioning Reference Signal, PRS) on multiple frequency points, since the PRS offset of each frequency point may be different, it may lead to different The PRS occasion on the frequency point cannot be covered by the same MG. At this time, the terminal device needs to re-apply for the MG from the network device (such as the serving base station), and the network device needs to reconfigure the MG. On the one hand, it brings signaling overhead and delay. On the other hand, since the effective time of the new MG is uncertain, the measurement time will be uncertain.

In addition, if the positioning measurement is non-disposable, the terminal device needs to periodically measure the reference signals of one or more frequency points, and the above request and reconfiguration process needs to be repeated, which greatly reduces the measurement efficiency.

The following describes the measurement interval configuration method provided by the embodiment of the present application in conjunction with FIG. 5. Taking the positioning measurement scenario as an example, the method includes:

101: The terminal device or the positioning server sends information related to positioning measurement to the access network device;

The relevant information of the positioning measurement may include the relevant information of one or more positioning frequency points, and for each positioning frequency point, it may include one or more of the following:

The period, offset (offset) and duration (also called duration) of PRS measurement, the absolute frequency point and bandwidth of PRS, the number of PRS occasions to be measured, etc.; the number of PRS occasions is greater than or equal to 1.

The positioning frequency point can also be called the Positioning frequency layer, or called the PRS frequency point; the PRS occasion can be called the PRS resource occasion. The access network device may be a serving base station.

The related information of the positioning measurement may also include the starting time point of the positioning measurement, for example: in the form of absolute time (UTC), or in the form of timing of the access network equipment (for example: offset relative to SFN0), or in the form of The form of the timer (for example: take effect after several ms).

The relevant information of the positioning measurement may also include the end time point of the positioning measurement, for example: in the form of absolute time (UTC), or in the form of timing of the access network equipment (for example: offset relative to SFN0), or in the form of timing The form of the device (for example: stop taking effect after a few ms).

The relevant information of the positioning measurement includes or indicates whether the positioning measurement is one-time. If it is one-time, it means that after the PRS occasion of each frequency point is measured once, the positioning measurement ends; if it is not one-time, it means that each frequency After each point is measured once, the PRS occasion of each frequency point is repeatedly measured.

For example: if the number of PRS occasions of frequency point 1 is 2, the number of PRS occasions of frequency point 2 is 3, and the positioning measurement is one-time, it means that the two PRS occasions of frequency point 1 are measured separately, and then the frequency points are measured separately. For the three PRS occasions of point 2, after the measurement is completed, the positioning measurement ends; if the positioning measurement is not one-time, it means to measure the two PRS occasions of frequency point 1 respectively, and then measure the three PRS occasions of frequency point 2 respectively, and then Measure the two PRS occasions of frequency point 1 again, measure the three PRS occasions of frequency point 2 again, and repeat the cycle.

Information related to positioning measurement may also include or indicate the number of positioning measurements. For example, if the number of positioning measurements is 2, it means that each frequency point is measured once, and then each frequency point is measured once, and then the positioning measurement ends.

For example: if the PRS occasion of frequency point 1 is 2, the PRS occasion of frequency point 2 is 3, and the number of positioning measurements is 2 times, measure the two PRS occasions of frequency point 1 respectively, and then measure the three PRS occasions of frequency point 2 PRS occasion, then measure the two PRS occasions of frequency point 1 again, and measure the three PRS occasions of frequency point 2 again, and then the positioning measurement ends.

The information related to the positioning measurement may also indicate or include the number of positioning measurements corresponding to each frequency point. For example, if the frequency point 1 positioning measurement frequency is indicated as 2 times, and the frequency point 2 positioning measurement frequency is 3 times, it means Frequency points 1 and 2 are measured once respectively, then frequency points 1 and 2 are measured again, and then frequency point 2 is measured again, and then the positioning measurement ends.

For example: if the PRS occasion of frequency point 1 is 2, the PRS occasion of frequency point 2 is 3, and the number of positioning measurements of frequency point 1 is 2 times, and the number of positioning measurement times of frequency point 2 is 3 times, then measure frequency point 1 respectively two PRS occasions of frequency point 2, then measure three PRS occasions of frequency point 2 respectively, then measure two PRS occasions of frequency point 1 again, measure three PRS occasions of frequency point 2 again, and then measure frequency point 2 again 3 PRS occasions, then the positioning measurement ends.

The above are some specific examples, but are not limited to the above examples, and various parameters in the related information of the positioning measurement may be used in any combination.

102: The access network device configures one or more MGs for the terminal device according to the positioning measurement related information;

The one or more MGs may be positioning-specific MGs or common MGs, and the access network device may send configuration information to the terminal device, including information about one or more MGs, and the one or more MGs may view As a group of MGs, for each MG, include one or more of the following:

MG period, offset (offset) and duration (also called duration); can be configured with reference to the period, offset and duration of PRS measurement in 101, or can be configured according to the actual situation;

Whether the MG is per UE (user equipment) or per FR, that is, the MG is effective for all serving cells of the terminal equipment, or is effective for serving cells within a certain frequency range (Frequency Range, FR);

The number of MG occasions; it can be configured by referring to the number of PRS occasions in 101, which is usually greater than or equal to the number of PRS occasions of the positioning frequency point associated with the MG.

The positioning frequency points associated with the MG, one MG can correspond to one or more positioning frequency points.

The configuration information may also include: MG effective time point, for example: in the form of absolute time (such as: Universal Time Coordinated, UTC), or in the form of timing of access network equipment (for example: relative to the system Frame number (system frame number) SFN0 offset), or in the form of a timer (for example: take effect after several ms).

The configuration information may also include: MG stop effective time point, for example: in the form of absolute time (UTC), or in the form of timing of access network equipment (for example: offset relative to SFN0), or in the form of timing The form of the device (for example: stop taking effect after a few ms).

The configuration information indicates whether the MG is one-off. If it is one-time, it means that after activating each MG once, each MG will not be activated again; if it is not one-time, it means that after activating each MG once, repeat Activate the respective MGs.

For example: if the MG occasion of MG 1 is 2, the MG occasion of MG 2 is 3, and the MG is one-time, it means that the two MG occasions of MG 1 are activated respectively, and then the three MG occasions of MG 2 are respectively activated; MG will no longer activate. If the MG is not one-time, it means activate two MG occasions of MG 1 respectively, and then activate three MG occasions of MG 2 respectively, then activate two MG occasions of MG 1 again, and activate three MG occasions of MG 2 again MG occasion, the cycle is repeated until the time point when the MG stops taking effect is reached or the access network device receives the instruction information of stopping the positioning measurement of the terminal device.

The configuration information may also include or indicate the number of MGs. For example, if the number of MGs is 2, it means that each MG is activated once, each MG is activated once, and each MG will not be activated after that.

For example: if the MG occasion of MG 1 is 2, the MG occasion of MG 2 is 3, and the number of MG times is 2, it means that the two MG occasions of MG 1 are activated respectively, and then the three MG occasions of MG 2 are respectively activated, and then Activate the two MG occasions of MG 1 again, respectively activate the 3 MG occasions of MG 2 again, and then each MG will not be activated again.

The configuration information may also indicate or include the number of MGs corresponding to each MG, for example: if the number of MG 1 is indicated to be 2 times, and the number of MG 2 is 3 times, it means that MG 1 and MG 2 are respectively activated once, Then activate MG 1 and MG 2 respectively, and then activate MG 2 again, and then each MG will not be activated again.

For example: if the MG occasion of MG 1 is 2, the MG occasion of MG 2 is 3, and the number of times of MG 1 is 2, and the number of times of MG 2 is 3, it means that the two MG occasions of MG 1 are activated respectively, and then respectively Activate the 3 MG occasions of MG 2, then activate the two MG occasions of MG 1 again, respectively activate the 3 MG occasions of MG 2 again, and then activate the 3 MG occasions of MG 2 again, and then each MG will no longer activation.

The above are some specific examples, but are not limited to the above examples, and various parameters of the MG in the configuration information can be used in any combination.

103: Access network equipment and terminal equipment activate the first MG;

When MG is activated, the access network device and the terminal device can preferentially use the relevant parameters of the MG configured by the access network device in 102. If no relevant parameters are configured in 102, the measurement-related parameters reported by the terminal device in 101 can also be used.

If the terminal device in 101 notifies the access network device of the starting time point of the positioning measurement, the access network device and the terminal device may activate the first MG at or after this time point; or

If the access network device in 102 notifies the terminal device of the MG effective time point, the access network device and the terminal device activate the first MG at or after the time point; or

Specifically, the first MG occasion of the first MG at or after this time point activates the first MG, and the first activated MG can be the first MG in the configuration information, or the MG with the smallest number , of course you can also set other MG as the first activated MG;

Otherwise, if the terminal device or the positioning server in 101 did not notify the access network device of the start time point of positioning frequency point measurement, or the access network device did not notify the terminal device of the effective time point of the MG in 102, the access network device can pass the signal command to activate a certain MG; for example: the access network device sends a MAC CE to the terminal device, and the MAC CE indicates the activation of MG#n, or activates MG#n through RRC configuration, or through RRC and downlink control information (downlink control information, DCI) to configure and activate MG#n.

The certain MG may also be indicated in the configuration information of 102, for example, if the configuration information indicates MG#n, then MG#n is first activated as the first activated MG.

Activating a certain MG means that each MG occasion corresponding to the MG is activated or takes effect on a periodic basis, and the terminal device can perform PRS measurement and report on each MG occasion.

The positioning server can configure the start time of positioning measurement or the window of positioning measurement to the terminal device, but the access network device does not know this information, so the terminal device needs to request the MG from the access network device before the measurement window, and the access network The device needs to reconfigure the MG for the terminal device. This process introduces additional signaling overhead. If the terminal device applies for the MG too early, it will cause unnecessary throughput loss in the service area because the positioning measurement is not started. If the terminal device applies for the MG too late, the positioning measurement cannot be started on time.

In the solution of the embodiment of this application, the access network device can pre-configure the effective time point of the MG based on the information provided by the positioning server or the terminal device about the start time point of the positioning measurement, so that the access network device and the terminal device at this time Point activation of the MG avoids the additional signaling process for the terminal to apply for the MG before the positioning measurement window, and the effective time of the positioning MG can be precisely aligned with the start time of the positioning measurement.

104: The access network device and the terminal device activate other MGs;

If the access network device in 102 notifies the terminal device of the number of MG occasions for each MG, the access network device and the terminal device will activate the next MG occasion after a period of time, such as a few milliseconds, after the last MG occasion of the first MG takes effect. MG, and so on, until all MGs are activated, and the MG occasions corresponding to each MG take effect sequentially; for example: access network equipment and terminal equipment activate MG# after [X _n ]ms after the last MG occasion of MG#n n+1, n=1...N, N is the number of MGs in the configuration information of 102 . X _n is the time interval between two MGs, and can take different values for different n.

For example: if the access network device configures two MGs for the terminal device, MG 1 and MG 2, MG 1 has 3 MG occasions, and MG 2 has 2 MG occasions, then activate MG 1's MG occasion 1 in turn, MG occasion 2 of MG 1, MG occasion 3 of MG 1, and then at an interval of 2ms, activate MG occasion 1 of MG 2 and MG occasion 2 of MG 2 in turn.

Otherwise, if the access network device in 102 does not notify the terminal device of the number of MG occasions for each MG, after the first MG ends, the terminal device can request the next MG occasion from the access network device through signaling, for example, through MAC CE. MG, the access network device instructs the terminal device to activate the next MG through signaling.

For example: the terminal device sends a MAC CE to the access network device, the MAC CE indicates the identity of the next MG, and the access network device sends a signaling to the terminal device to activate the MG indicated by the aforementioned MAC CE.

The following example describes the process of positioning measurement:

For example: if the access network device configures two MGs for the terminal device, the MG occasion of MG 1 is 2, and the MG occasion of MG 2 is 3, and the MG is one-time, the terminal device and the access network device activate the MG first 1. The two MG occasions of MG 1 take effect separately by cycle, and then activate MG 2, and the three MG occasions of MG 2 take effect respectively by cycle. The terminal device performs PRS measurement in each MG occasion. After the measurement is completed, the positioning measurement ends. Terminal equipment and access network equipment no longer activate MG 1 and MG 2; if the MG is not one-off, the terminal equipment and access network equipment activate MG 1 first, and the two MG occasions of MG 1 take effect on a periodic basis, and then activate MG 2, the three MG occasions of MG 2 take effect respectively according to the cycle; then the terminal device and the access network device activate MG 1 again, the two MG occasions of MG 1 take effect respectively according to the cycle, and then activate MG 2, the three of MG 2 The MG occasions take effect separately in a period, and the terminal device performs PRS measurement in each MG occasion, and repeats the cycle until the MG stops taking effect or the access network device receives the indication information sent by the terminal device to stop the positioning measurement.

The configuration information may also include or indicate the number of MGs. For example, if the number of MGs is 2, it means that each MG is activated once. After the MG occasions corresponding to each MG take effect in turn, each MG is activated once. Each MG The corresponding MG occasions take effect again in turn, and the terminal device performs PRS measurement within the MG occasions of each MG, and then the positioning measurement ends.

For example: if the access network device configures the MG occasion number of MG 1 for the terminal device to be 2, the MG occasion number of MG 2 to be 3, and the number of MG occasions is 1, then the terminal device and the access network device activate MG 1 first, The two MG occasions of MG 1 take effect respectively by cycle, and then activate MG 2, and the three MG occasions of MG 2 take effect respectively by cycle. The terminal device performs PRS measurement in each MG occasion. After the measurement is completed, the positioning measurement ends, and the terminal device And access network equipment no longer activate MG 1 and MG 2; if the number of MGs is 2 times, the terminal equipment and access network equipment activate MG 1 first, and the two MG occasions of MG 1 take effect on a periodic basis, and then activate MG 2 , the three MG occasions of MG 2 take effect on a periodic basis, and then the terminal equipment and access network equipment activate MG 1 again, the two MG occasions of MG 1 take effect on a periodic basis, and then activate MG 2 again, and the three MGs of MG 2 Occasions take effect on a periodic basis. The terminal device performs PRS measurement in each MG occasion, and then the positioning measurement ends, and the terminal device and access network device no longer activate MG 1 and MG 2.

For example: if the access network device is configured for the terminal device, the number of MG occasions of MG 1 is 2, the number of MG occasions of MG 2 is 3, and the number of times of MG 1 is 2, and the number of times of MG 2 is 3, then the terminal device And the access network equipment first activates MG 1, and the two MG occasions of MG 1 take effect respectively by cycle, and then activates MG 2, and the three MG occasions of MG 2 take effect respectively by cycle, and then the terminal device and the access network device activate MG again 1. The two MG occasions of MG 1 take effect respectively by cycle, activate MG 2 again, the three MG occasions of MG 2 take effect respectively by cycle, and then activate MG 2 again, the three MG occasions of MG 2 take effect by cycle respectively, the terminal The device performs PRS measurement in each MG occasion, and then the positioning measurement ends, and the terminal device and access network device no longer activate MG 1 and MG 2.

If no relevant MG parameters are configured in step 102, parameters related to positioning measurement in step 101 may be used instead.

When a terminal device needs to measure multiple PRS frequencies, and PRS occasions on different frequency points cannot be covered by the same MG, the terminal device needs to re-apply for an MG from the access network device, and the access network device needs to reconfigure the MG. On the one hand, it brings signaling overhead and time delay; on the other hand, because the effective time of the new MG is uncertain, it will cause uncertainty in the measurement time. In addition, if the positioning measurement is non-one-time, that is, the terminal device needs to perform periodic measurement on one or more PRS frequency points, the above request and reconfiguration process needs to be repeated.

Based on the solutions of the embodiments of the present application, when the access network device pre-configures multiple MGs for the terminal device for positioning measurement, the access network device and the terminal device determine to activate a certain MG without additional signaling interaction. Specifically, the access network device determines the number of corresponding MG occasions required by the terminal device to complete the measurement of a certain PRS frequency point according to the information such as the PRS frequency point to be tested, and pre-configures the number of MG occasions to the terminal device. Access network devices and terminal devices activate the next MG by default after the last MG occasion of a certain MG, so as to achieve seamless switching between multiple MGs without additional signaling interaction and avoid MG reconfiguration , so as not to cause prolongation and uncertainty of the measurement time.

105: The access network device and the terminal device deactivate the MG;

If the access network device in 102 notifies the terminal device of the number of MG occasions of each MG, the access network device and the terminal device perform deactivation according to the following conditions after the last MG occasion of the last MG ends:

If the access network device in 102 notifies the terminal device that the MG stops taking effect, the access network device and the terminal device do not exceed this time point at the end of the last MG occasion of the last MG, then the access network device and the terminal device Reactivate the first MG and repeat step 104 until the time point when the MG stops taking effect is reached, and then the access network device and the terminal device perform a deactivation operation to deactivate the current MG.

If the access network device in 102 notifies the terminal device that the MG is not one-off, after the last MG occasion of the last MG ends, the access network device and the terminal device reactivate the first MG and repeat 104 ; If the access network device also notifies the terminal device of the number of repetitions of the MG, after the number of repetitions is completed, perform a deactivation operation to deactivate the currently activated MG. If the number of MG repetitions is not notified, the terminal device can deactivate the MG according to the time when the MG stops taking effect, or request to deactivate the MG through signaling. The sending of the signaling can be triggered based on certain conditions, for example: the terminal device Send MAC CE to the access network equipment to notify the access network equipment to deactivate the MG.

If the access network device in 102 notifies the terminal device MG is one-off, after the last MG occasion of the last MG ends, the access network device and the terminal device perform deactivation operations, and the deactivation ends An activated MG.

The deactivation operation means that the one or more MGs are not repeatedly activated, and the one or more MGs become invalid.

In another case, regardless of whether the access network device in 102 indicates the number of each MG occasion to the terminal device, the terminal device may request the access network device to deactivate each MG in 102 through signaling.

When the positioning measurement is non-one-time, after the terminal device completes a round of positioning measurement, for example, after measuring multiple PRS frequency points, it needs to perform the next round of measurement, that is, re-measure the first PRS frequency point and other PRS frequency. The terminal device may need to apply for an MG from the access network device, and the access network device needs to be reconfigured to configure the MG for the terminal device.

In the solution of the embodiment of the present application, the access network device may preconfigure the effective end time of one or more MGs or whether it is one-off and The number of repetitions, and then the access network device and the terminal device can determine whether the MG is repeated or deactivated according to the pre-configured information, that is, determine whether to activate a positioning MG again or deactivate all positioning MGs, so as to realize the MG without additional signaling interaction Under certain circumstances, in the case of periodic or multiple positioning measurements, MG reconfiguration is avoided, which will not cause measurement time extension and uncertainty, and can also avoid signaling overhead caused by explicitly deactivating the MG.

In addition, when a certain MG is active, if the terminal equipment supports non-MG measurement at its associated positioning frequency point, that is, it does not need to configure the MG, and can also perform reference signal measurement. At this time, the terminal equipment has strong capabilities and supports Data is transmitted while reference signal measurements are performed. For example: if the frequency interval formed by the absolute frequency point and bandwidth configured by the access network device described in 101 is within the frequency interval of the serving cell, and the terminal equipment has the capability of measuring without MG, then the duration of the MG occasion corresponding to the MG It can be used for data scheduling in the serving cell. The terminal device and the access network device can send and receive data within the time of the MG occasion, and there may be restrictions on the data sending and receiving. other serving cells outside or outside the frequency band, or terminal equipment and access network equipment transmit and receive data on time-domain symbols other than the symbol where the PRS resources are located, or other situations, this application does not make any limit.

When an MG used for positioning measurement is in the active state, if the total number of the active MG and other MGs exceeds the total number of active MGs that the terminal equipment can support, one or more other The MG is deactivated, and other MGs are MGs for non-positioning measurement, for example: MGs for radio resource management (radio resource management, RRM) measurement.

If the RRM MG is used for PCC or PSCC measurement, the MG cannot be deactivated, so an MG in an active state other than for PCC or PSCC measurement can be deactivated.

It is also possible to deactivate at least one of the MG with the lowest priority, the MG with the smallest number of associated MOs, the MG with the largest period, or the MG with the largest index among other MGs in the activated state. Corresponding thresholds can be set to deactivate activated MGs that are lower or higher than the set thresholds.

If the MG used for positioning measurement is deactivated, the other MGs that were deactivated may resume the activated state.

When the number of simultaneously activated MGs and other MGs for positioning measurement exceeds the capability limit of the terminal equipment, in the absence of additional signaling interaction, to determine which other MG to deactivate, it is necessary to consider the minimum value of the terminal mobility measurement Minimize the impact and enable reactivation of other MGs after deactivation of the positioning MG.

In this embodiment, reference signal measurement in a positioning scenario is taken as an example for illustration. The above-mentioned reference signal can be a PRS, but is not limited to a PRS. However, the MG configuration method of this application can be used not only in a positioning scenario, but also in other scenarios. The reference signal can be Reference signal for other scenes.
