In the existing wireless communication system, an activation time is configured in a discontinuous reception (Discontinuous Reception, DRX) cycle, and a user performs detection of a downlink control channel and some measurement and reporting operations during the activation time. During the inactive time, the user is in a sleep state, and the user performs less measurement and detection, so that some software and hardware modules can be turned off, and therefore less power is consumed.

Detailed Description

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the new wireless (Next Radio generation, NR) phase, studies on location enhancement techniques have been performed in order to address the location requirements of new business use cases, including general business applications and industrial internet of things applications. The related art has conducted a study of positioning in a wireless communication system, and the study and standardization of positioning have been conducted from the viewpoints of higher accuracy, network and user efficiency, and the like.

In a wireless system, the system configures discontinuous reception (Discontinuous Reception, DRX) parameters for a connected User (UE), and the User does not need to detect a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and does not need to detect a periodic channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS) during an inactive time (may also be referred to as a sleep period) in the DRX state, so that the User can go into deep sleep. However, in the positioning related provision, the positioning measurements do not take into account the DRX configuration or are only for non-DRX configurations, i.e. the positioning measurements are independent of whether DRX is configured or not. The UE expects to meet the same measurement requirements, whether in active or inactive periods of the DRX cycle, which may mean that the UE may need to measure the positioning reference signal outside of the DRX active time (i.e., sleep period), otherwise the UE may not meet the requirements for positioning measurements, which the UE trades off at the expense of power. In other words, in NR, when the UE activates the positioning function, all measurement procedures are performed under the assumption of non-DRX, which may mean that the UE must remain activated to perform reception and measurement of the positioning reference signal, and the NR system needs to consume power to support the positioning function.

Referring to fig. 1, fig. 1 is a flowchart of an information acquisition method according to a first embodiment of the present invention, where the method is applied to a first base station, and includes the following steps:

Step 11: the first base station acquires first information of a terminal to be positioned in an adjacent base station, wherein the first information comprises discontinuously received configuration related information of the terminal to be positioned or time information for actually receiving and transmitting positioning reference signals, and the discontinuously received configuration related information of the terminal to be positioned comprises discontinuously received configuration information related to an activation period and/or configuration information related to a dormancy period.

After the first base station obtains first information of a terminal to be positioned in an adjacent base station, the first base station only sends or receives the positioning reference signal in an activation period of discontinuous reception of the terminal to be positioned or only sends or receives the positioning reference signal in a time of actually receiving and transmitting the positioning reference signal by the terminal to be positioned according to the first information.

Specifically, if the first base station determines that the terminal does not transmit or receive the positioning reference signal during the sleep period of discontinuous reception, the first base station may transmit or receive the positioning reference signal only during the active period of discontinuous reception of the terminal to be positioned, or only during the time when the terminal to be positioned actually transmits or receives the positioning reference signal.

The first base station corresponds to a first cell, and the adjacent base stations correspond to adjacent cells. The above step 11 can thus also be described as: the first cell acquires first information of a terminal to be positioned in a neighboring cell. The same is true below, and will not be described again.

The first base station may determine the start and end time of DRX off and/or the time when the user actually transmits and receives the positioning reference signal (or referred to as the time when the positioning reference signal is actually transmitted) according to the first information.

The active period (DRX on) of discontinuous reception may also be referred to as an active period, and the sleep period (DRX off) of discontinuous reception may also be referred to as an inactive period or an inactive period.

The first base station and the service base station to which the terminal to be positioned belongs are adjacent base stations.

The Positioning reference signals include Positioning reference signals (Positioning REFERENCE SIGNALS, PRS) and/or Sounding Reference Signals (SRS) REFERENCE SIGNALS. PRS is issued by base station and measured by terminal; the SRS is transmitted by the terminal and detected by the base station.

And the terminal to be positioned does not need to transmit and receive the positioning reference signal in the sleep period of discontinuous reception.

The base station may specifically be a 5G base station (gNB), or may be a Transmission/Reception Point (TRP), or may be other devices having the same or similar devices, which are not described in detail herein.

For example, during positioning, an adjacent base station (or an adjacent cell) of a serving base station to which a terminal to be positioned belongs needs to measure an SRS, if the terminal does not send the SRS during DRX off, the adjacent base station of the serving base station to which the terminal to be positioned does not know the start and stop time of DRX off, does not know the period of time when the terminal does not send the SRS, and the adjacent base station of the serving base station still considers that there is an SRS during DRX off, measures the SRS and sends the measured information to a positioning management functional entity (Location Management Function, LMF), so that the LMF uses the wrong information to estimate the position of the terminal, further resulting in error position estimation and reduced positioning accuracy.

In addition, the first base station also reports positioning measurement information obtained by measuring the SRS to the LMF. Of course, the first base station may report the measured information directly to the LMF, or may report the measured information to the LMF after processing the measured information, for example, estimate information related to the user location according to the measured information.

The above positioning method is exemplified below.

The first base station receives the first information sent by the adjacent base stations through interfaces between the base stations; that is, the neighboring base station (i.e., the first base station) is directly notified by the serving base station;

Or alternatively

The first base station receives the first information sent by a positioning management functional entity, and the positioning management functional entity receives the first information from the adjacent base station. Specifically, the first information may be in a positioning information response, the serving base station informs the LMF, and the LMF informs the neighboring base station (i.e., the first base station) of the serving base station through a positioning measurement request or a new signaling.

Optionally, the method further comprises at least one of:

The base station configures the terminal to determine whether to transmit and receive the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception, or may preset the terminal to determine whether to transmit and receive the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception. Further, the threshold for determining the period of discontinuous reception may be configured by the serving base station or may be predetermined.

Referring to fig. 2, fig. 2 is a flow chart of a positioning method according to a second embodiment of the present invention, the method is applied to a positioning management functional entity, and includes the following steps:

Step 21: the positioning management functional entity obtains first information of a terminal to be positioned, wherein the first information comprises discontinuously received configuration related information of the terminal to be positioned or time information for actually receiving and transmitting positioning reference signals, and the discontinuously received configuration related information of the terminal to be positioned comprises discontinuously received configuration information related to an activation period and/or configuration information related to a dormancy period;

the positioning management functional entity can determine starting and ending time of DRX off and/or time of a user actually receiving and transmitting positioning reference signals according to the first information.

Step 22: the positioning management functional entity determines the validity of the received positioning measurement information according to the first information;

Step 23: and the positioning management functional entity calculates the position information of the terminal to be positioned according to the effective positioning measurement information.

The positioning measurement information may specifically be measurement information obtained by measuring, by a base station (including a serving base station and/or a neighboring base station of the serving base station), a positioning reference signal sent by a terminal, or may also be measurement information obtained by measuring, by a terminal, a positioning reference signal sent by a base station (including a serving base station and/or a neighboring base station of the serving base station).

Of course, the base station may report the measured information directly to the LMF, or may report the measured information to the LMF after processing the measured information, for example, estimate the information related to the user location according to the measured information. The terminal processes the measured positioning measurement information similarly to the base station.

In the embodiment of the invention, the base station (including the serving base station and the adjacent base station of the serving base station, or the adjacent base station of the serving base station only) still performs SRS measurement in the DRX off phase, and reports the result to the LMF, and the LMF judges whether the result is an effective measurement result according to the measurement time stamp of the received positioning measurement information and the first information.

Of course, the positioning management functional entity also needs to acquire whether the terminal to be positioned performs the transmission and reception of the positioning reference signal in the sleep period of discontinuous reception. If the terminal to be positioned does not receive and transmit the positioning reference signal in the sleep period of discontinuous reception, the validity of the received positioning measurement information can be determined according to the first information. If the terminal to be positioned receives and transmits the positioning reference signal in the sleep period of discontinuous reception, all the received positioning measurement information can be considered to be valid.

Optionally, the first information is carried in a position information response or a positioning measurement response. The location information response may also be referred to as a positioning information response, which is a response of the serving base station to a positioning information request transmitted by the LMF to the serving base station when positioning is performed based on the uplink positioning reference signal.

Optionally, the method further comprises at least one of:

That is, the serving base station may configure whether the terminal transmits and receives the positioning reference signal in the sleep period of discontinuous reception, or may preset whether the terminal transmits and receives the positioning reference signal in the sleep period of discontinuous reception, or may determine whether the terminal transmits and receives the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception.

In the method, whether the terminal transmits or receives the positioning reference signal in the sleep period of discontinuous reception is determined according to the period of discontinuous reception, and it is to be noted that:

The service base station can configure the terminal to determine whether the terminal transmits and receives the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception, or preset the terminal to determine whether the terminal transmits and receives the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception;

The positioning requirement is usually related to the service of the user, that is, when the service allowable delay of the user is larger, the delay requirement of positioning is also larger, and then it can be determined according to the DRX cycle, whether to allow the transmission and the reception of the positioning reference signal in the DRX off phase. In particular, it may be provided that when the DRX cycle is greater than a preset value (e.g., 80 ms), measurements of positioning are not allowed during DRX off; when the DRX cycle is smaller than a preset value (e.g., 80 ms), the positioning process ignores the configuration of the DRX cycle, and can also perform the transmission and reception of the positioning reference signal during the DRX off period. The preset value may be configured by the base station or may be predefined.

In other optional embodiments, the location management function entity may also receive notification information sent by the serving base station, and determine whether the terminal to be located performs transmission and reception of the location reference signal in a sleep period of discontinuous reception according to the notification information.

In the embodiment of the invention, the service base station corresponds to a service cell, and the adjacent base station corresponds to an adjacent cell.

Referring to fig. 3, fig. 3 is a flowchart of an information interaction method according to a third embodiment of the present invention, where the method is applied to a second base station, and includes the following steps:

Step 31: the second base station sends first information of the terminal to be positioned to a first base station or a positioning management functional entity;

The second base station is a serving base station of the terminal to be positioned, the first base station is a neighboring base station of the second base station, the first information includes discontinuously received configuration related information of the terminal to be positioned or time information for actually transceiving positioning reference signals, and the discontinuously received configuration related information of the terminal to be positioned includes discontinuously received configuration information related to an activation period and/or configuration information related to a sleep period.

The first base station corresponds to a first cell, the second base station corresponds to a second cell, the second cell is a service cell of the terminal to be positioned, and the first cell and the second cell are adjacent cells. That is, the above step 31 may be described as: the second cell sends the first information of the terminal to be positioned to the first cell or the positioning management functional entity. Hereinafter, the description is similar and will not be repeated.

In the embodiment of the invention, the adjacent base station of the service base station to which the terminal to be positioned belongs can acquire information related to discontinuous receiving configuration of the terminal to be positioned and/or time for actually receiving and transmitting positioning reference signals, so that the adjacent base station of the service base station to which the terminal to be positioned belongs can transmit or receive the positioning reference signals in a time period in which the terminal to be positioned can transmit and receive the positioning reference signals, thereby improving positioning precision and reducing energy consumption. Or the base station (including the serving base station and the adjacent base station of the serving base station or the adjacent base station of the serving base station only) still performs SRS measurement in the DRX off stage, and reports the result to the LMF, and the LMF judges whether the result is a valid measurement result according to the measurement time stamp of the received positioning measurement information and the first information.

Optionally, the method further comprises:

and the second base station sends positioning configuration information to the terminal to be positioned, wherein the positioning configuration information is used for indicating whether the terminal receives and transmits positioning reference signals in a sleep period of discontinuous reception.

In other optional embodiments, the positioning configuration information may be used to instruct the terminal to determine, according to a period of discontinuous reception, whether the terminal performs transmission and reception of the positioning reference signal in a sleep period of discontinuous reception. Furthermore, the positioning configuration information may be further used for indicating a judging threshold value of the discontinuous reception period, so that whether the terminal performs the transmission and reception of the positioning reference signal in the sleep period of discontinuous reception can be determined according to the discontinuous reception period of the terminal and the judging threshold value. For example, when the DRX cycle is greater than the decision threshold, the reception and transmission of the positioning reference signal is not performed during the sleep period of discontinuous reception; and when the DRX period is smaller than the judging threshold value, transmitting and receiving the positioning reference signal in the sleep period of discontinuous reception. Of course, the judgment threshold value may not be indicated by the positioning configuration information, but by additional information.

Optionally, the method further comprises:

the second base station sends notification information to the first base station or the positioning management functional entity, wherein the notification information is used for indicating whether the terminal to be positioned receives and transmits positioning reference signals in a sleep period of discontinuous reception.

In the conventional wireless communication system, since the terminal cannot enter the sleep state when the DRX is off in order to perform positioning, the energy saving function of the DRX off is not enabled.

The above-mentioned positioning method proposed for solving the problem that the transmission of the user positioning reference signal is only allowed to be performed in the DRX on phase is exemplified below, and the neighbor base station of the serving base station and the LMF do not have the relevant information of DRX on, which results in the decrease of the positioning accuracy.

Referring to fig. 4, fig. 4 is a positioning process based on an uplink SRS, and a processing flow of a serving base station (i.e., a second base station) is as follows:

The first step: the Serving base station (Serving) receives NRPPa a location information request (NRPPa POSITIONING INFORMATION REQUEST) sent by the LMF, corresponding to step 2 in fig. 4.

And a second step of: the serving base station determines Uplink (UL) SRS resources (gNB determines UL SRS Resources), corresponding to step 3 in fig. 4; and transmitting an SRS configuration (UE SRS configuration) to the UE, corresponding to step 3a in fig. 4; transmitting a location information response (NRPPa POSITIONING INFORMATION RESPONSE) to the LMF, corresponding to step 4 in fig. 4; the UE transmission SRS (Activate UE SRS transmission) is activated, corresponding to step 5 in fig. 4.

And a third step of: the serving base station receives the measurement request (NRPPa MEASUREMENT REQUEST) sent by the LMF, corresponding to step 6 in fig. 4, starts to perform SRS measurement (UL SRS Measurements), corresponding to step 7 in fig. 4, and sends a measurement response (NRPPa MEASUREMENT RESPONSE) to the LMF, corresponding to step 8 in fig. 4, and needs to inform the user of the start and end time of actually sending the positioning SRS when the positioning operation is performed in the LMF DRX cycle (i.e. whether the terminal performs SRS transmission in the DRX off phase).

According to the working mechanism of the DRX, it can be known that the time length of the DRX ACTIVE TIME is not fixed, and related to the arrival situation of downlink signaling and data and the short DRX cycle configuration situation, the serving base station cannot notify the LMF and the neighboring cell in advance more time, and needs to notify the LMF of the time of actually transmitting the SRS before the LMF performs the position calculation. The specific notification time point is a new step that may be added at step 4 or step 8 in fig. 4, or before the LMF position solution. The serving base station informs the LMF of the time point if the energy consumption of the neighboring base stations is not considered, the LMF may be informed in step 8 in fig. 4.

In addition, according to the actual application scenario, the serving base station informs the LMF or the neighboring cells (the cells corresponding to the neighboring base stations) of the corresponding positioning operation under the DRX off of the user and the time period for the user to actually receive the PRS and/or report the positioning result. Or the serving base station informs the LMF of the corresponding positioning operation under the DRX off of the user, and the starting and ending time of the DRX off or the time period when the user actually transmits SRS and/or the user actually receives PRS and/or reports the positioning result, and the LMF transmits the information to the adjacent cell. And will not be described in detail herein.

For the LMF process flow, please refer to fig. 4, mainly including:

The first step: the LMF and each base station perform signaling interaction of positioning information request and response;

And a second step of: the LMF and each base station carry out signaling interaction of positioning measurement request and response, and before and after the LMF receives the positioning measurement response of each base station, the time period of the terminal actually transmitting the positioning SRS or the starting and ending time of DRX off are received;

And a third step of: the LMF performs a position solution.

In other embodiments, for example, in the positioning process based on the downlink PRS, the LMF processing flow mainly includes:

the LMF performs signaling interactions of positioning information and measurement requests and responses with each base station. Before and after the LMF receives the positioning measurement response of each base station, the time period of the actual transmission of the positioning reference signal and/or the time period of DRX off of the UE reported by the base station are received.

The LMF and each UE perform signaling interactions of positioning measurement requests/measurements and responses.

The LMF performs a position solution.

Referring to fig. 5, fig. 5 is a flowchart of a positioning method according to a fourth embodiment of the present invention, where the method is applied to a terminal, and includes the following steps:

Step 51: the terminal receives positioning configuration information sent by the base station, wherein the positioning configuration information is used for indicating whether the terminal receives and transmits positioning reference signals in a sleep period of discontinuous reception.

And then, the terminal can determine whether to transmit and receive the positioning reference signal in the sleep period of discontinuous reception according to the positioning configuration information.

That is, in the DRX off phase, the user may be configured to transmit or receive a positioning reference signal.

The embodiment of the invention provides a method for configuring whether a terminal receives or receives a positioning reference signal or not in a sleep period of discontinuous reception by a base station, so that positioning operation can be configured according to the requirements of delay and energy consumption, and the design for reducing delay is performed while energy conservation is met.

In particular, the positioning can be applied to various scenes, the requirements of different services on power consumption are different, and the requirements of different scenes on positioning time delay are different. When the energy saving requirement of the system is high, but the requirement on time delay is not high, the system should support the DRX function, so that the user can enter deep sleep, and under the condition that the positioning time delay is not high, the user can be required to not measure when the DRX is off.

That is, if the transmission and reception of the positioning reference signal is not performed during the sleep period of discontinuous reception, the power consumption of the terminal can be reduced, but this causes an increase in positioning delay. If the transmission and reception of the positioning reference signal are still performed during the sleep period of discontinuous reception, the power consumption is increased although the positioning delay is not increased. Thus, positioning operations may be configured according to latency and power consumption requirements, e.g., unnecessary positioning measurements may be turned off according to scene requirements, thereby conserving power consumption.

One specific implementation manner of the embodiment of the invention can be as follows:

the first step: the base station performs positioning measurement under the condition of configuring or presetting DRX;

And a second step of: if the configuration mode is adopted by the base station, the base station sends the configuration value to the user. For example, "1" indicates that the positioning reference signal is transmitted and received in the DRX off phase, and "0" indicates that the positioning reference signal is not transmitted and received in the DRX off phase.

In another optional embodiment, the positioning configuration information may be used to instruct the terminal to determine whether the terminal performs the transmission and reception of the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception. Furthermore, the positioning configuration information may be further used for indicating a judging threshold value of the discontinuous reception period, so that whether the terminal performs the transmission and reception of the positioning reference signal in the sleep period of discontinuous reception can be determined according to the discontinuous reception period of the terminal and the judging threshold value. For example, when the DRX cycle is greater than the decision threshold, the reception and transmission of the positioning reference signal is not performed during the sleep period of discontinuous reception; and when the DRX period is smaller than the judging threshold value, transmitting and receiving the positioning reference signal in the sleep period of discontinuous reception. Of course, the judgment threshold value may not be indicated by the positioning configuration information, but by additional information.

Whether or not the user is making location measurements during the DRX off phase may be transparent to the LMF from the cell, since only location related data is measured, the user will report to the LMF.

Existing systems support periodic positioning configurations, with non-periodic positioning configurations in the discussion phase. Positioning configuration of cycle once configuration is completed, when the positioning cycle and the DRX cycle are different, the positioning process may fall in the DRX off phase. The aperiodic positioning is controlled by the base station based on signaling. Therefore, this embodiment proposes that the different active state positioning measurements of DRX are only for periodic measurements, and are independent of DRX for non-periodic positioning measurements, i.e. no DRX is configured or not, no DRX processing is configured.

That is, when the positioning operation is configured according to the demands of delay and power consumption, different processes are performed for periodic positioning and non-periodic positioning.

Alternatively, the base station may configure the terminal to determine whether to transmit and receive the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception, or may preset the terminal to determine whether to transmit and receive the positioning reference signal in the sleep period of discontinuous reception according to the period of discontinuous reception.

Further, the threshold for determining the period of discontinuous reception may be configured by the serving base station or may be predetermined.

Referring to fig. 8, fig. 8 is a flowchart of a positioning configuration method according to a seventh embodiment of the present invention, where the method is applied to a base station, and includes the following steps:

Step 81: the base station sends positioning configuration information to a terminal; the positioning configuration information is used for indicating whether the terminal receives and transmits positioning reference signals in a sleep period of discontinuous reception.

The first step: if the positioning measurement under the DRX condition is configured by the base station, the terminal receives the DRX measurement condition configured by the base station.

And a second step of: the terminal performs positioning measurement according to the configuration of the base station or the preset rule.

In another optional embodiment, the positioning configuration information may be used to instruct the terminal to determine whether to perform transceiving of the positioning-related reference signal in a sleep period of discontinuous reception according to a discontinuous reception period.

Furthermore, the positioning configuration information may be further used for indicating a judging threshold value of the discontinuous reception period, so that whether the terminal performs the transmission and reception of the positioning reference signal in the sleep period of discontinuous reception can be determined according to the discontinuous reception period of the terminal and the judging threshold value. For example, when the DRX cycle is greater than the decision threshold, the reception and transmission of the positioning reference signal is not performed during the sleep period of discontinuous reception; and when the DRX period is smaller than the judging threshold value, transmitting and receiving the positioning reference signal in the sleep period of discontinuous reception. Of course, the judgment threshold value may not be indicated by the positioning configuration information, but by additional information.

The first step: and the service base station receives NRPPa positioning information requests sent by the LMF.

And a second step of: and the service base station determines positioning RS resources and sends the configuration of the RS resources to the UE.

The base station sends positioning measurement configuration to the user, and the user is configured to not measure when DRX off, so that the user enters deep sleep, and power consumption is saved.

Whether DRX off performs positioning measurements or not may be implemented in a predefined manner by the protocol.

And a third step of: and the service base station starts SRS measurement after receiving the measurement request, and sends a measurement response to the LMF to inform the LMF user of the starting and ending time of actually sending the positioning SRS.

In the third step, the service base station informs the LMF user of the start and end time of actually sending the positioning SRS, and the LMF selects effective position information estimation to calculate according to the start and end time of the positioning SRS, so that the estimation precision under DRX off is improved.

and step two, the UE transmits SRS or performs downlink positioning measurement.
