Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
Embodiments of the present invention are described below with reference to the accompanying drawings. The SRS reporting processing method and the related equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.
Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a user terminal or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). The network device 12 may be a 5G base station, a later-version base station, or a base station in another communication system, or referred to as a node B, an evolved node B, or a Transmission Reception Point (TRP), an Access Point (AP), or another vocabulary in the field, and the network device is not limited to a specific technical vocabulary as long as the same technical effect is achieved. In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.
Step 201, determining measurement feedback information according to measurement information corresponding to a target signal, where the measurement feedback information is used to determine first configuration information, and the first configuration information is used to configure a cell signal of the terminal;
step 202, reporting the measurement feedback information;
the target signal comprises N first signals and M second signals, the first signals are configured cell signals and the second signals are unconfigured cell signals, the cell signals comprise SRS associated spatial relation signals and SRS associated path loss reference signals, the cell signals comprise signals of a serving cell and signals of adjacent cells, and N and M are positive integers.
In the embodiment of the present invention, the network device may configure N first signals for the terminal, and after the network device configures N first signals for the terminal, the terminal may perform measurement and report autonomously, may perform measurement according to an instruction of the network device, and may perform reporting according to an instruction of the network device. When the network device instructs the terminal to perform measurement and/or reporting, it can be generally understood that the network device instructs the terminal to perform measurement and/or reporting on a part of cell signals specified in the configured N first signals. There are also special cases where at least one of the following operations is performed for the indication terminal:
for a specified part of the configured N first signals, obtaining N first signals;
and measuring and/or reporting signals of a part of cells appointed by the M second signals.
For example, the network device may configure the terminal to measure and/or report signals of a part of cells through the configuration information, or may request the terminal to measure and/or report signals of a part of cells through the request message.
Optionally, the cell Signal may include at least one of a Synchronization Signal block (Synchronization Signal and PBCH block, SSB), a downlink Positioning Reference Signal (DL-PRS), and a Channel State Information Reference Signal (CSI-RS).
The above-mentioned non-configured cell signal can be understood as a cell signal which is not selected as a spatial relationship signal and/or a path loss reference signal of an SRS signal by the SRS signal in the serving cell and the neighboring cell. The N first signals may include a cell signal of a serving cell and a cell signal of a neighboring cell, and the M second signals may include a cell signal of a serving cell and/or a cell signal of a neighboring cell.
The measurement feedback information may include measurement information of a part or all of the target signal, or may include a measurement condition corresponding to the measurement information of the part or all of the target signal. Optionally, in an embodiment of the present invention, the measurement feedback information specifically may include at least one of the following:
cell identification information and identification information of cell signals;
a measured value corresponding to a cell signal;
identification information of a first path cell signal of a serving cell;
identification information of a first path cell signal of an adjacent cell;
a cell signal measurement failure identifier;
configuring a reasonable identifier for a cell signal;
and configuring unreasonable identification for cell signals.
The above measurement value may be understood as at least one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Noise and Interference plus Noise Ratio (SINR) of the cell Signal.
Further, the above measurement values may also be understood as an arrival time measurement value and an arrival angle measurement value of a reference signal of a cell signal.
The unreasonable cell signal configuration identifier and the reasonable cell signal configuration identifier may be an identifier reflecting whether the configuration of a specific cell signal is reasonable or not, or may be an identifier reflecting whether the configuration of all cell signals is reasonable or not. For example, when a signal measurement of a certain cell fails, a cell signal measurement failure flag may be fed back for the cell signal, and the cell signal configuration reasonable flag and the cell signal configuration unreasonable flag may be feedback information on whether all currently configured cell signals are configured reasonably or not, or may be feedback information on whether a signal of a certain cell is configured reasonably or not. Specifically, when the configured cell signals include 8 cell signals, and the measurement quality of the three cell signals is poor, or the measurement fails, or the measurement value is poor, three unreasonable configurations may be fed back corresponding to the three cell signals and/or five reasonable configurations of identifiers may be fed back corresponding to the remaining five cell signals. And only the unreasonable signal configuration identifier of the cell can be fed back to reflect that the signal of the cell configured last time is unreasonable. At this time, the network device may perform cell signal reconfiguration again based on other auxiliary information, and certainly, in the case that the measurement feedback information includes the measurement value of the unconfigured cell signal, the network device may reconfigure the cell signal for the terminal based on the measurement value of the unconfigured cell signal and the previously configured cell signal.
After receiving the measurement feedback information, the network device may determine the first configuration information. Specifically, the first configuration information may be understood as configuration information of a cell signal corresponding to next SRS transmission, and for example, when the configuration information of the next cell signal is not changed, the target configuration information transmitted last time may be directly transmitted to the terminal, or the target configuration information transmitted last time may not be transmitted. In the case that the configuration information of the next cell signal changes, at this time, the first configuration information may be the configuration information obtained after updating the target configuration information sent last time, and at this time, the first configuration information may be sent to the terminal.
The network device may be understood as a serving cell or a positioning reference server, and is not further limited herein. The serving cell may configure a cell signal for the terminal through Radio Resource Control (RRC) signaling, and the positioning reference server may configure the cell signal for the terminal through an LTE Positioning Protocol (LPP) or an evolution thereof.
In the embodiment of the invention, the terminal feeds back the measurement information of the signals of the serving cell and the adjacent cell, so that the network equipment can determine the configuration of the cell signal of the terminal according to the fed back measurement feedback information. Therefore, the network equipment can update the configuration of the cell signal of the terminal in time so as to improve the reliability and effectiveness of uplink positioning.
Optionally, the manner in which the terminal reports the measurement feedback information may be set according to actual needs, for example, in the embodiment of the present invention, step 202 includes any one of the following:
mode 1, reporting the measurement feedback information periodically;
in the mode 2, the measurement feedback information is reported according to a first request message sent by the network equipment;
and in the mode 3, reporting the measurement feedback information according to a preset rule.
According to the embodiment of the invention, different reports can be set according to the actual condition of the terminal, so that the flexibility of terminal reporting is improved.
Optionally, as for the mode 1, the network device is configured or the protocol-agreed terminal is configured to report periodically, specifically, the reported content may be agreed by the protocol or may be configured by the network device.
For the above mode 2, the network device may request the terminal to report, specifically, the network device may send a first request message to the terminal, where the first request message is used to request the terminal to measure a P1 cell signal, the P1 is a positive integer, and the P1 cell signal includes part or all of the target signal. When the terminal performs cell measurement based on the first request message, the reported measurement feedback information includes a measurement result corresponding to each cell signal in the P1 cell signals, where the measurement result includes a measurement value of the cell signal or measurement failure identification information of the cell signal. Of course, in other embodiments, the measurement feedback information may also include other information, such as a cell signal configuration reasonable identifier or a cell signal configuration unreasonable identifier.
As for the above mode 3, it can be understood that the terminal autonomously reports according to the rule configured in advance and agreed by the protocol. The reporting of the measurement feedback information according to the preset rule can be understood as that the terminal reports based on a trigger event, wherein the preset rule can be understood as a corresponding event. Optionally, the reporting of the measurement feedback information according to the preset rule includes one of:
reporting mode 3.1, reporting the measurement feedback information under the condition that N1 first signals meet a first preset condition and/or the measurement values of M1 second signals are all smaller than a first preset value, wherein the measurement feedback information includes a cell signal configuration reasonable identifier, N1 is a positive integer smaller than or equal to N, and M1 is a positive integer smaller than or equal to M;
a reporting mode 3.2, reporting the measurement feedback information under the condition that the target signal meets a second preset condition;
and a reporting mode 3.3, reporting the measurement feedback information when the number of times that the target signal meets the second preset condition is greater than a preset number of times within a preset time period.
In the above mode 3.1, the first preset condition may include at least one of:
the measured value of the first signal is greater than the measured value of each second signal, and the difference between the measured value of the first signal and the measured value of the second signal is greater than a second preset value;
the measured value of the first signal is greater than the measured value of a third signal, and the third signal is a cell signal except the N first signals in a cell to which the first signal belongs;
the time measurement result of the first signal is the first path of the cell to which the first signal belongs;
the measured value of the first signal is greater than a third preset value.
In this embodiment of the present invention, the first preset condition and the condition that the measurement values of M1 second signals are both smaller than the first preset value may be understood as a condition that the cell signal configuration is not changed, and in a case that the condition that the measurement values are not changed is satisfied, the reported measurement feedback information may include a cell signal configuration reasonability identifier, and at this time, it may be understood that the cell signal configured last time is reasonable, or the configuration of the cell signal does not need to be changed. Certainly, in some optional embodiments, when the condition of not changing is satisfied, the terminal may expect not to report, and at this time, the terminal may not report the measurement feedback information. In other words, the network device may not update the cell configuration of the terminal when the measurement feedback information is not received or the received measurement feedback information indicates that the cell signal is not changed (e.g., identification information that does not need to be changed).
The size of each preset value can be set according to actual needs, and optionally, in the embodiment of the present invention, each preset value is a positive number. Among these, in an alternative embodiment, the following are included but not limited to: the first preset value is set to be greater than or equal to a third preset value.
Optionally, after the step 202, the method further includes:
receiving the first configuration information sent by a network device, where the first configuration information is used to indicate that identification information of the N first signals is maintained unchanged or is used to carry identification information of an L1 cell signal, the L1 cell signal is used to update the N first signals, and L1 is a positive integer.
First indication information for indicating that the identification information of the N first signals is maintained;
identification information of the N first signals;
and under the condition that the configuration mode of the cell information of the terminal is a holding mode (such as a need M), the first configuration information does not carry the identification information of the cell signal.
It should be noted that the configuration mode of the cell signal of the terminal may include a hold mode or a non-hold mode, and in the hold mode, the terminal may store the configuration information of the cell signal. When the cell signal is not changed, the terminal may perform measurement using the stored cell signal configuration information. In this embodiment of the present invention, when the cell signal is not changed, the network device may not send the first configuration information, or may send the first configuration information, where the first configuration information may indicate to maintain the identity information of the N first signals unchanged, or the first configuration information is the configuration information of the cell signal sent last time, or the sent first configuration information may not carry the identity information of the cell signal.
Optionally, when the cell signal is changed, the network device sends first configuration information, where the first configuration information carries identification information of the L1 cell signal. In this embodiment, the L1 cell signals include a sixth signal and N2 first signals, the sixth signal is a cell signal of the M second signals, the sixth signal is used to replace a seventh signal of the N first signals, N2 is an integer, and the N2 first signals are cell signals of the N first signals except for the seventh signal.
In an optional embodiment, the sixth signal is a cell signal recommended by the terminal or a cell signal selected by the network device, the seventh signal is a cell signal in which there are K1 times of measurement failures, and K1 is a positive integer. In the embodiment of the invention, the terminal can report the recommended cell signals according to the measurement result, and the quantity of the recommended cell signals can correspond to the quantity of the first signals which are considered by the terminal to be replaced. Because the terminal recommends the cell signal for replacement, the updating pertinence of the first signal can be improved, and the reliability and the accuracy of the next uplink positioning measurement can be further ensured. Specifically, the network device may use a cell signal recommended by the terminal as the sixth signal, or may determine the cell signal as the sixth signal according to other auxiliary information.
Further, the terminal can also recommend the cell signals needing to be added or deleted. For example, whether to report the recommended cell signal may be determined according to the measurement information corresponding to the second signal, where the recommended cell signal is used for increasing. Meanwhile, the terminal may recommend the cell signal to be deleted, for example, it may determine whether to report the recommended cell signal according to the measurement information corresponding to the first signal, where the recommended cell signal is used for deletion.
In another alternative embodiment, the sixth signal is the second cell signal which meets the second preset condition and reaches K2 times, the seventh signal is the first cell signal which meets the second preset condition and reaches K2 times, and K2 is a positive integer. In the embodiment of the present invention, the second preset condition may be a change condition, for example, when the second preset condition defines both the first signal and the second signal, the sixth signal and the seventh signal are cell signals whose number of times satisfying the second preset condition reaches K2 times. In the embodiment of the present invention, because the definition of K2 is added, flexibility of cell signal change can be flexibly set, for example, when K2 is greater than 1, frequency of cell change can be reduced, thereby reducing overhead of signaling, and avoiding a situation that a cell signal is falsely triggered to change due to inaccurate transient measurement of a certain cell signal caused by shielding or other reasons.
Optionally, in an optional embodiment, the second preset condition includes at least one of the following:
a condition 1, in which a first measured value of at least one first signal in the N first signals is smaller than a second measured value of a fourth signal, and a difference between the first measured value and the second measured value is greater than a fourth preset value, the fourth signal is one of the M second signals;
condition 2, a measured value of at least one first signal of the N first signals is smaller than a fifth preset value;
condition 3, at least one first signal of the N first signals fails to measure;
a condition 4 that at least one fifth signal exists in the M second signals, the fifth signal and the at least one first signal are located in the same cell, and a time measurement result of the fifth signal is a primary path of a cell to which the fifth signal belongs;
a condition 5 that a measured value of at least one first signal of the N first signals is greater than a sixth preset value;
and 6, the measured value of at least one second signal in the M second signals is greater than a seventh preset value.
Optionally, taking a second preset condition including condition 3 and condition 6 as an example, at this time, the sixth signal is a cell signal whose measured value is greater than a seventh preset value among the M second signals; the seventh signal is a cell signal in which the number of times of measurement failures is greater than K2 times among the N first signals.
Optionally, the size of each preset value may be set according to actual needs, for example, in the embodiment of the present invention, each preset value is a positive number. Among these, in an alternative embodiment, the following are included but not limited to: the fifth preset value may be smaller than the sixth preset value, and the seventh preset value may be greater than or equal to the sixth preset value.
Optionally, when at least one of the condition 1 and the condition 2 is met to trigger reporting of the measurement feedback information, the measurement feedback information includes at least one of the following:
identification information of the replacement cell signal;
measurements of replacement cell signals;
identification information of the original cell signal;
a measurement of an original cell signal;
the replacement cell signal is a cell signal used for replacing the original cell signal in the M second signals, and the original cell signal is a replaced cell signal in the N first signals.
Optionally, when the condition 3 is met and reporting of the measurement feedback information is triggered, the measurement feedback information includes:
an identification signal of a cell signal which fails to be measured;
and identifying the measurement failure of the cell signal with the measurement failure.
Optionally, when the condition 4 is met and the measurement feedback information is triggered to be reported, the measurement feedback information includes at least one of the following:
identification information of the replacement signal;
replacing a first path signal identification of a cell signal;
identification information of the original cell signal;
the replaced cell signal is the fifth signal, and the original cell signal is a replaced cell signal in the N first signals.
Optionally, when at least one of the condition 5 and the condition 6 is met to trigger reporting of the measurement feedback information, the measurement feedback information includes:
identification information of cell signals of which the measured values are higher than the eighth preset value;
the measurement value of the cell signal is higher than the eighth preset value.
It should be noted that, when different conditions are met, the content reported by the corresponding measurement feedback information is different, and the operation executed by the corresponding network device is also different, which is described in detail below.
In an embodiment, the measurement feedback information includes:
identification information of a first replacement cell signal;
a measurement of a first alternative cell signal;
identification information of a first original cell signal;
a measurement of a first original cell signal;
the first replacement cell signal is a cell signal used for replacing the original cell signal in the M second signals, and the first original cell signal is a replaced cell signal in the N first signals.
In this embodiment, the network device may determine the first configuration information according to the following manner:
and determining whether to replace the identification information corresponding to the first original cell signal in the target configuration information with the identification information corresponding to the first replacement cell signal to obtain the first configuration information according to the measurement value of the first replacement cell signal and the measurement value of the second signal, wherein the target configuration information comprises the N first signals. In this embodiment of the present invention, the number of the first replacement cell signals and the number of the first original cell signals may be the same. For example, for a case of a first original cell signal and a first replacement cell signal, the network device may determine that a measurement value according to the first replacement cell signal is compared with a measurement value of the first original cell signal, and in a case of being greater than a preset threshold, may replace the first original cell signal with the first replacement cell signal. Specifically, the identification information of the first original cell signal in the target configuration information is replaced with the identification information of the first replacement cell signal. When the number of first original cell signals may include Q1 (Q is an integer greater than 1), the network device may replace Q2 first original cell signals with Q2(Q2 is a positive integer less than or equal to Q1) first replacement cell signals based on comparing the measured value of the first replacement cell signal with the measured value of the first original cell signal.
In another embodiment, the measurement feedback information includes:

In the embodiment of the present invention, the network device may select any one of the modes 4 to 6 according to an actual situation to perform a corresponding operation.
In another optional embodiment, the measurement feedback information comprises:
identification information of the second replacement signal;

identification information of a second original cell signal;
the second replacement cell signal is a cell signal in the M second signals, the second original cell signal and the second replacement signal are located in the same cell, and a time measurement result of the second replacement signal is a first path of a cell to which the second replacement signal belongs.
In this embodiment, the network device may determine the first configuration information according to the following manner:
and determining whether to replace the identification information corresponding to the second original cell signal in the target configuration information with the identification information corresponding to the second replacement cell signal to obtain the first configuration information according to the first path signal identification of the second replacement cell signal, wherein the target configuration information comprises the N first signals.
In the embodiment of the invention, the second original cell signal in the cell to which the second replacement signal belongs is replaced and updated based on the second replacement signal of which the time measurement result is the first path of the cell to which the second replacement signal belongs, so that the uplink measurement quality can be improved, and the reliability and the accuracy of uplink positioning are ensured.
In another optional embodiment, the measurement feedback information comprises:
identification information of T tenth signals;
measurements of the T tenth signals;
the T tenth signals are cell signals of which measured values are higher than an eighth preset value among the M second signals, and T is a positive integer less than or equal to M.

Each cell signal of the T1 tenth signals is different from the T2 tenth signals, which may be understood as the absence of an intersection between the T1 tenth signals and the T2 tenth signals.
Further, when the terminal fails to measure the first signal and is not configured or does not store the time-frequency resource information corresponding to the first signal, the method further includes:
sending a second request message to the network device;
and receiving second configuration information sent by the network device in response to the second request message, wherein the second configuration information includes time-frequency resource information corresponding to the first signal.
In the embodiment of the present invention, when the network device configures the first signal, corresponding time-frequency resource information may not be configured for a part of the first signal in order to save overhead. At this time, the terminal may request the network device to perform time-frequency resource information configuration by sending the second request message when the first signal measurement fails and the failure reason is not configured or the corresponding time-frequency resource information is not stored. After receiving the second request message, the network device sends second configuration information to the terminal, in an optional embodiment, the second configuration information may include time-frequency resource information corresponding to the first signal, and in another optional embodiment, the second configuration information may further include time-frequency resource information corresponding to the second signal, so that the terminal may measure the second signal.
It should be noted that the first signal included in the second configuration information is a first signal that fails to be measured due to lack of time-frequency configuration in the N first signal measurements, and the second signal included in the second configuration information is a second signal of the same cell as the first signal that fails to be measured due to lack of time-frequency configuration. For example, when the cell signal 1 fails to perform time-frequency configuration measurement due to lack of time-frequency configuration, the terminal may send a second request message to the network device, and at this time, the network device sends second configuration information to the terminal based on the second request message, where the second configuration information includes a time-frequency resource corresponding to the cell signal 1, and further includes a time-frequency resource corresponding to a cell signal 2, where the cell signal 2 and the cell signal 1 belong to the same cell, and the cell signal 2 is a cell signal in M second signals.
Further, in case of a handover of the terminal, the method further comprises:
receiving third configuration information sent by a network device, where the third configuration information includes an L2 cell signal, the L2 cell signal includes a cell signal of a serving cell before handover, a cell signal of a serving cell after handover, and a cell signal of an adjacent cell, and L2 is a positive integer;
updating the N first signals according to the L2 cell signals.
Wherein the L2 cell signals include added cell signals and deleted cell signals, the added cell signals are different from the N first signals, and the deleted cell signals are part or all of the N first signals.
In the embodiment of the present invention, the third configuration information may be understood as updating the N first signals configured by the target configuration information, and in the switched scene, the first signals configured by the terminal are updated through the third configuration information, so that the updating time is ensured, and the reliability and accuracy of the uplink positioning are further improved.
It should be noted that, in the case that it is determined to update the target configuration information, the updated configuration may be sent to the corresponding neighboring cell. Specifically, in the embodiment of the present invention, the behavior of the network device specifically includes:
sending fourth configuration information to an adjacent cell corresponding to an eighth signal under the condition of sending target configuration information to the terminal, wherein the target configuration information is used for configuring the N first signals for the terminal, and the fourth configuration information is used for indicating a cell signal of the terminal pointing to the adjacent cell direction;

when the target configuration information is the updated configuration of the cell signal, the eighth signal is a cell signal whose configuration state changes, where the change of the configuration state includes a change of the configured cell signal into an unconfigured cell signal and a change of the unconfigured cell signal into a configured cell signal.
In this embodiment, when the network device performs cell handover to update a cell signal configured for the terminal, or when the network device updates a cell signal configured for the terminal due to a measurement result, the network device may send the updated configuration to a corresponding neighboring cell. Specifically, when the network device is a serving cell, the serving cell may send the updated configuration information to the corresponding neighboring cell through X2 or Xn; when the network device is a Location Management Function (LMF), the Location server may send the updated configuration information to the corresponding neighboring cell through a New Radio Position Protocol (NRPPA) or its evolution. At this time, if the neighboring cell receives a cell signal corresponding to the neighboring cell configured to the terminal by the network device, the receiving beam of the neighboring cell preferentially adopts the transmitting direction of the cell signal as the receiving beam direction.
Further, when the terminal performs cell signal measurement, the measurement may be performed according to the configuration of the network device, may also be performed autonomously according to protocol agreement, and may also be performed according to a request of the network device. For example, in an embodiment of the present invention, before step 201, the method further includes:
receiving target information sent by network equipment, wherein the target information comprises measurement configuration or measurement request;
and measuring partial or all cell signals of the target signal according to the target information.
Wherein the measuring of part or all of the cell signals of the target signal according to the target information comprises at least one of:
measuring part or all of the N first signals;
some or all of the M second signals are measured.
It should be noted that, in the embodiment of the present invention, when the network device configures or requests measurement, the network device may measure the specified cell signal and/or the specified measurement information, and after the measurement is completed, the network device may directly report the corresponding measurement information, or report the measurement information according to a request of the network device, which is not limited further herein. The network device may be a serving cell or a positioning server, and in the embodiment of the present invention, the following scheme may be specifically included:
the serving cell triggers the terminal to measure cell signals of the serving cell and the neighbor cell through measurement configuration or a measurement request; or the serving cell triggers the terminal to measure the cell signals of the neighbor cells through measurement configuration or measurement requests; or the positioning server triggers the terminal to measure cell signals of the serving cell and the adjacent cell through measurement configuration or a measurement request; or the positioning server triggers the terminal to measure the cell signal of the adjacent cell through measurement configuration or measurement request; or the positioning server triggers the terminal to measure the cell signal of the serving cell through the measurement configuration or the measurement request.

wherein the preset information comprises at least one of the following:
location information of the terminal and the neighboring cell;
spatial direction configuration of cell signals of neighboring cells.
It should be noted that, when the measurement quality of the network device or a certain cell is poor, the terminal may be started to perform cell measurement and reporting operations. Specifically, in the embodiment of the present invention, the network device may send, to the terminal, third indication information in a case of receiving second indication information sent by a target cell, where the second indication information is used to indicate that measurement quality of the target cell is lower than a threshold, and the third indication information is used to indicate that the terminal performs cell measurement and reporting operations.
It should be understood that the cell participating in positioning may send the measured quality of the cell to the network device, where the measured quality may be understood as a normalized value or a quality score value obtained by calculating through a preset formula. The measurement quality of the target cell being lower than the threshold value may be understood as that the measurement quality of the target cell is poor, in other words, the measurement value of the cell signal of the target cell is poor for a plurality of times, or the degree of hopping of the measurement values for a plurality of times is large.
For better understanding of the present invention, the following detailed description of the implementation of the present invention is given by way of specific examples.
In a first embodiment, a serving cell configures or updates a cell signal of an SRS signal for a terminal. Referring to fig. 3 and 4, the method specifically includes the following steps:

When the serving cell configures the cell signal a through RRC, the corresponding SRS configuration information at least includes identification information of the cell signal a. Further, the SRS configuration information may further include time-frequency resources of the cell signal a and/or time-frequency resources of the cell signal B.
The identification information of the cell signal a is carried in the SRS configuration information, and the identification information of the cell signal a may include at least one of the following:

Optionally, the time-frequency resource of the cell signal a may include a time-frequency resource of a target SSB signal, and if the serving cell does not configure the target SSB signal to the terminal and does not know whether the terminal detects the target SSB signal, when the cell signal a is configured, the SRS configuration information needs to include the target SSB signal, and further the SRS configuration information may also include the time-frequency resource of the target SSB signal. It should be noted that, when the time-frequency resource of the target SSB signal is not configured, the terminal may request the serving cell to perform configuration in a subsequent process. The time-frequency resources of the target SSB signal include at least one of:
a cell identity or a TRP identity;
SSB frequency domain location;

Optionally, the time-frequency resource of the cell signal a may include a time-frequency resource of a target DL PRS signal, and if the serving cell does not configure the target DL PRS signal to the terminal and does not know whether the terminal detects the target DL PRS signal, when the cell signal a is configured, the SRS configuration information needs to include the target DL PRS signal, and further the SRS configuration information may further include the time-frequency resource of the target DL PRS signal. It should be noted that, when the time-frequency resource of the target DL PRS signal is not configured, the terminal may request the serving cell to perform configuration in a subsequent process. The time-frequency resources of the target DL PRS signal include at least one of:
a cell identity or a TRP identity;

Optionally, the time-frequency resource of the cell signal may be a time-frequency resource target of a CSI-RS signal, and the time-frequency resource of the CSI-RS signal includes at least one of the following:

CSI-RS ID；
time domain position, SFN offset, slot offset, period;

And step 2, the terminal measures the cell signal and reports the cell signal measurement result.
Optionally, the measurement of the terminal occurs before RRC configuration, or the measurement of the terminal occurs after RRC configuration and before SRS signal transmission.
Optionally, the terminal may search a measurement result of a cell signal configured by the last serving cell, and correspondingly feed back corresponding measurement feedback information to the serving cell according to the measurement information of each cell signal. Wherein the measurement result may comprise at least one of: RSRP, RSRQ, SINR, Time of Arrival (TOA), and first-path cell signal identity.
In an embodiment, if there is a cell signal measurement failure, the reported measurement feedback information includes measurement failure information. Alternatively, the measurement failure information may be represented by the SRS resource identifier and/or the first information (cell signal identifier information and failure identifier information). For example, it can be expressed as: the cell signal identifier information and the enumeration information { failure, no failure }, where optionally, the measurement failure information may further include an SRS resource identifier.
For example, if the cell signal configured by the serving cell last time includes cell signal 1, cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6, if the measurement of cell signal 2 fails, the measurement feedback information reported at this time may include measurement failure information corresponding to all cell signals, or may only include measurement failure information of cell signal 2.
Optionally, the failure of the terminal to report the cell signal 2 measurement may be reporting according to a preset period, or reporting when a request sent by the serving cell is received. It should be understood that, in the embodiment of the present invention, the cell signal failure may be reported only when the number of times of measurement failure of a certain cell signal within a period of time is greater than a predetermined number of times. For example, the number of times of measurement failures of cell signal 1 is 3, the number of times of measurement of cell signal 2 is 6, and the preset number of times is 5. At this time, in the reported measurement failure information, the enumeration information corresponding to the cell signal 1 is no failure, and the enumeration information corresponding to the cell signal 2 is failure.
In another optional embodiment, if there is a cell signal with a suitable cell signal measurement result, the configuration is reported reasonably or the identifier is not required to be changed to the serving cell, and no information may be fed back to the serving cell for the cell signal.
Further, the measurement report configuration is reasonable or the identity is not required to be changed, which may be represented by the SRS resource identity and/or the second information (the cell signal identity information and the failure identity information). For example, it can be expressed as: the cell signal identification information and the enumeration information { reasonable, unreasonable }, optionally, may further include an SRS resource identifier.
In the embodiment of the present invention, the determination of whether the cell signal is a suitable cell may be performed by combining the first preset condition and/or the second preset condition in the above embodiment. For example, when the measured value of a certain cell signal is good, the cell signal can be considered as a suitable cell signal.
For example, in the case that the cell signal configured by the last serving cell includes cell signal 1, cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6, in the case that it is determined that cell signal 1 is an unsuitable cell signal, and it is determined that cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6 are suitable cell signals, in an embodiment, the measurement feedback information may report a reasonable or non-modified identifier for cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6, and feed back a specific measurement result or an unreasonable identifier for cell signal 1, in other words, the enumeration information corresponding to cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6 may be reasonable, the corresponding enumeration information for cell signal 1 may not be justified. In another embodiment, the measurement feedback information may only feed back specific measurement results for the cell signal 1, and does not feed back measurement information or unreasonable configuration identifiers of the signal 2, the cell signal 3, the cell signal 4, the cell signal 5, and the cell signal 6.
In yet another optional embodiment, if there is a cell signal that is better suited for a certain SRS resource, the third information (new cell signal identification information and measurement result) and/or the fourth information (original cell signal identification information and measurement result) is reported.
Optionally, the measurement reporting configuration may be represented as: the cell signal identification information and the measurement result may further include an SRS resource identification.
In the embodiment of the present invention, the new cell signal refers to a cell signal that has not been configured last time, and the original cell signal refers to a cell signal that has been configured last time.
For example, in the case that the cell signal configured by the serving cell last time includes cell signal 1, cell signal 2, cell signal 3, cell signal 4, cell signal 5, and cell signal 6, it is determined through measurement that cell signal 7 (unconfigured cell signal) and cell signal 8 (unconfigured cell signal) are more suitable as the cell signal of the SRS resource, and the reported measurement feedback information may carry the identification information and measurement result of cell signal 7, and the identification information and measurement result of cell signal 8. If it is determined through measurement that the cell signal 1 is not suitable as the cell signal of the SRS resource, the reported measurement feedback information may carry the identification information and the measurement result of the cell signal 1.
Alternatively, in the case where the serving cell receives only the identification information and measurement result of the cell signal 7, and the identification information and measurement result of the cell signal 8, the configured cell signal may be added and/or replaced. When the serving cell receives only the identification information and the measurement result of the cell signal 1, the configured cell signal 1 may be deleted and/or replaced, for example, the cell signal 1 may be deleted alone, or the cell signal 1 may be replaced.
Further, when the serving cell receives the identification information and the measurement result of the cell signal 7, and the identification information and the measurement result of the cell signal 1, the cell signal 1 may be replaced with the cell signal 7.
Optionally, the measurement occurs after RRC configuration and before SRS signal transmission.
In one embodiment, the terminal needs to transmit without measuring all or part of cell information, and the part of the terminal which fails to measure scans and transmits with a maximum power beam according to the configured resource. Further, the terminal uploads the cell signal measurement failure to the serving cell. Further, the terminal uploads the SRS transmission configuration to the serving cell.
In another embodiment, the terminal does not send all or part of SRS signals in this period, and uploads the identifier, reference time and non-transmission indication corresponding to the non-transmission SRS.
And step 3, the serving cell updates or maintains the cell signal configuration.
In the method 1, if one or more measurements of a cell signal in the cell signal a fail, the cell signal is updated, where the updated cell signal may be a cell signal recommended by a terminal or a cell signal selected by a serving cell according to other auxiliary information (e.g., location information);
in the method 2, if a cell signal in the cell signal B is reported by the UE one or more times and the measurement quality is good or far better than the cell signal corresponding to the selected cell, the serving cell updates the reported cell signal to be the cell signal corresponding to the SRS resource.
In the method 3, if the serving cell does not change the cell signal configuration information, the cell signal configuration information is maintained to be configured to the terminal.
Optionally, the cell signal may be maintained by repeatedly sending the last configuration information, or setting the configuration mode of the cell information to be need M, and when the configuration is lacked, maintaining the configuration stored in the terminal before.
And 4, the service cell sends the update to a positioning server.
Alternatively, as shown in fig. 3, in an embodiment, the serving cell may send the update to the positioning server through NRPPA or its evolution. Further location servers send updates to neighbor cells through NRPPA or its evolution. Furthermore, the adjacent cell can select the direction of the received beam through the cell signal, thereby reducing the beam scanning and searching time and increasing the detection gain.
Optionally, as shown in fig. 4, in another embodiment, the serving cell sends the update corresponding to the neighbor cell through an X2 or an Xn interface or its evolution. Furthermore, the adjacent cell can select the direction of the received beam through the cell signal, thereby reducing the beam scanning and searching time and increasing the detection gain.
