The following describes a channel measurement processing method provided in the embodiment of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
In the embodiment of the present application, a User Equipment (UE) may refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal may also be a cellular telephone, a cordless telephone, a session initiation protocol (sessioninitiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA), a handheld device having wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device.
As shown in fig. 2, a channel measurement processing method in an embodiment of the present application is applied to a terminal, and includes:
step 201, sending a first signaling to a target cell; wherein,
the first signaling is used for activating or deactivating a target cell transmission channel measurement related signal of the terminal; the target cell comprises a serving cell and/or a neighbor cell of the terminal.
In this way, the terminal can directly activate or deactivate the transmission of the channel measurement related signal in the target cell by sending the first signaling to the target cell, i.e. the serving cell and/or the neighboring cell of the terminal, so as to reduce the delay of channel measurement and meet the timeliness requirement for obtaining the reference signal for channel measurement according to step 202.
Therefore, for the terminal applying the method of the embodiment of the application, for the scene with positioning requirement, the first signaling is sent to the service cell and/or the adjacent cell of the terminal, namely the service cell and/or the adjacent cell can be activated to transmit the relevant signal for channel measurement, and the reference signal for channel measurement is timely obtained; and the first signaling is sent to the service cell and/or the adjacent cell of the terminal without the positioning scene, so that the related signal of the transmission channel measurement of the service cell and/or the adjacent cell can be deactivated, and the consumption of signaling resources is avoided.
It should be appreciated that the target cell is a cell of a network-side device (e.g., a base station, a transmission Reference Point (Transmission Reference Point, TRP), a Reference Point (RP), a radio frequency head, etc.).
Optionally, in this embodiment, the transmission channel measurement related signal includes at least one of:
Transmitting a second signaling, wherein the second signaling is used for activating or deactivating the neighbor cell to receive a reference signal or activating or deactivating the terminal to transmit the reference signal;
the reference signal is measured.
In this embodiment, the reference signal is a signal for channel measurement. Here, the second signaling is signaling for activating or deactivating the target cell measurement reference signal transmitted after the specific cell (e.g., a cell for positioning control, such as a serving cell) receives the first signaling. Specifically, the specific cell may send the second signaling to the target cell of the terminal; alternatively, the particular cell may also send this second signaling to a location management device, such as an LMF, via which the target cell measurement reference signal is activated or deactivated. Wherein the LMF may further activate or deactivate the target cell measurement reference signal through signaling, which may be of the same design as the first signaling.
Or, the specific cell sends the second signaling to the terminal, and activates or deactivates the terminal to send the reference signal.
The measurement reference signal may also be understood as receiving reference information, based on which measurements are made.
For example, in the case that the target cell is a serving cell and a neighboring cell, or the target cell is a neighboring cell, the first signaling is used to activate or deactivate the target cell to receive the reference signal; in the case that the target cell is a serving cell, the first signaling is used to activate or deactivate the target cell to send the second signaling and receive the reference signal.
Optionally, the reference signal includes at least one of:
a reference signal SRS for periodic channel detection;
aperiodic SRS;
semi-static SRS;
physical random access channel PRACH signal.
As such, the reference signals for channel measurement may include, but are not limited to: periodic channel sounding reference signals (Sounding Reference Signal, SRS), aperiodic SRS, semi-static SRS, physical random access channel (Physical Random Access Channel, PRACH) signals.
As can be seen from the above, the channel measurement related signal may be a second signaling and/or reference signal, and thus, optionally, the channel measurement related signal transmitted by the target cell includes at least one of the following:
determining the transmitted channel measurement related signal;
determining the received reference signal;
and determining the sent second signaling.
That is, the target cell performs determination of the channel measurement related signal transmitted, determination of the reference signal received, determination of at least one of the transmitted second signaling, and transmission according to the determined contents, in case that the first signaling is received.
Wherein determining the transmitted channel measurement related signal, i.e. determining whether the target cell is currently transmitting the second signaling or receiving the reference signal, or both, is required. The received reference signal, i.e. which reference signal the target cell receives, how it receives, etc., is determined, as it were, the configuration information of the received reference signal. Determining the second signaling to send, i.e. determining which second signaling to send by the target cell, how to send the second signaling, the relation between the second signaling and the reference signal, etc. it can also be said that the configuration information of the second signaling is to be sent.
Optionally, the determining the received reference signal includes determining at least one of:
the identification ID or group ID or terminal identification ID of the reference signal;
the transmission time of the reference signal;
a transmission period of the reference signal;
the number of times of transmission of the reference signal;
the time of reception of the reference signal;
a reception period of the reference signal;
the number of times of receiving the reference signal;
time-frequency resources of the reference signal;
the number of the reference signals;
spatial relationship of the reference signals;
power information of the reference signal;
And receiving or stopping receiving the reference signal.
Wherein the time-frequency resources include, but are not limited to: symbol number, time offset, frequency domain information (e.g., frequency domain reference point pointA, bandwidth BW, comb structure comb, frequency domain offset, frequency hopping information, etc.). The number of reference signals may be the number of resources (resource) or the number of resource sets (resource sets).
Optionally, in this embodiment, the reference signal is determined according to at least one of:
configuration information of the pre-configured reference signals;
predefined configuration information of the reference signal;
configuration information of the dynamically scheduled reference signals;
the first signaling.
Here, the first signaling indicates the received reference signal by carrying configuration information of the reference signal or by a correspondence existing between the configuration information of the reference signal. In this way, the target cell may directly receive the reference signal based on the configuration information of the pre-configured reference signal, may directly receive the reference signal based on the configuration information of the pre-defined reference signal, may directly receive the reference signal based on the configuration information of the dynamically scheduled reference signal, and may directly receive the reference signal based on the first signaling. Of course, the configuration information of the received reference signal may also be determined by at least two of the configuration information of the pre-configured reference signal, the configuration information of the pre-defined reference signal, the configuration information of the dynamically scheduled reference signal, and the first signaling to complete the reference signal based channel measurement.
Example 1, the target cell receives the reference signal according to configuration information (e.g., sequence ID, cyclic shift, transmission time, transmission period, number of transmissions, number, spatial relationship, time-frequency resource, power information) of the reference signal preconfigured by the LMF or the network side device.
In example 2, if the network side is configured with N1 reference signals (such as an aperiodic SRS or a periodic SRS), then M1 reference signals in the N1 reference signals can be determined to be received in combination with the first signaling, where M1 is an integer, and 1 is equal to or greater than 1 and equal to or less than N1. Of course, the simultaneous determination may further include at least one of a reception time, a reception period, a reception number, a time-frequency resource, and power information.
In example 3, if the network side configures N2 reference signals, M2 reference signals in the N2 aperiodic SRS may be determined to be received by combining the first signaling and the configuration information of the predefined reference signals or the configuration information of the LMF preconfigured reference signals, where M2 is an integer, and 1 is less than or equal to M2 is less than or equal to N2. Of course, the simultaneous determination may further include at least one of a reception time, a reception period, a reception number, a time-frequency resource, and power information.
Optionally, the first signaling includes at least one of:
PRACH signal;
SRS；
Uplink control information UCI;
the signal characteristics satisfy the target signal of the second preset condition.
And the first target uplink resource.
Of course, the first signaling includes, but is not limited to: PRACH signal, SRS, uplink control information (Uplink Control Information, UCI), target signal with signal characteristics satisfying a second preset condition, and first target uplink resource.
As such, taking the PRACH signal as the first signaling as an example, in example 2 above for determining to receive the reference signal SRS, at least one of the following may be performed:
a1 Determining corresponding reference signals according to the corresponding relation between the root sequences of different PRACH and the reference signals;
b1 Determining a corresponding reference signal according to RO (PRACH Occasion) resources in the current PRACH sequence;
c1 Determining a corresponding reference signal according to the uplink information carried by the RO resource.
Here, if the corresponding reference signals are determined according to a combination of a 1) and b 1), such as: the index of the first reference signal is determined according to a 1), and the target reception occasion of the aperiodic reference signal is determined according to b 1), the target cell can perform the reception of the first reference signal at the target reception occasion.
In example 3 above where the received reference signal is determined, at least one of the following may be performed:
a2 A specific preamble (preamble) sequence (e.g., generated according to a specific root sequence, or what preamble (i.e., which of 64 preambles) is used for activating reception of the reference signal) is agreed in the current PRACH sequence;
b2 A predetermined resource (such as a predetermined RO resource for transmitting a target random access preamble sequence random access opportunity) in the current PRACH sequence is used to activate the reception of the reference signal, wherein the predetermined RO resource is dynamically configured in configuration information transmitted by the network side or predefined;
c2 Determining a corresponding reference signal according to the uplink information carried by the RO resource.
Here, if the corresponding reference signals are determined according to a combination of a 2) and b 2), such as: the index of the second reference signal is determined according to a 2), and the target reception occasion of the reference signal is determined according to b 2), the target cell may perform reception of the second reference signal at the target reception occasion.
The target reception timing of the first reference signal or the second reference signal may be determined according to the activation time T1 and the time offset T2, for example, the target reception timing (for example, the reception time) is t1+t2. Here, T2 may be a fixed value configured based on terminal capabilities, configured based on network side capabilities, or predefined; but may also be a variable, such as a change according to the configuration of the first signaling (e.g., resource, root sequence, etc.). In this embodiment, the reception timing is not limited to the reception time, but includes the number of times of reception, the reception period, and the like. It should be appreciated that the reception timing for the reception side corresponds to the transmission timing for the transmission side.
Of course, the implementation of using the PRACH signal as the first signaling is also applicable to the SRS, UCI, and the target signal and the first target uplink resource whose signal characteristics meet the second preset condition, which are not described herein again.
In this embodiment, the first target uplink resource may be directly used as the first signaling, and in consideration of that configuration information of the first signaling may be used to determine the received reference signal, alternatively, the first signaling may be used as the first signaling by carrying configuration information of the first signaling by the first target uplink resource, and combining the first target uplink resource with at least one of the PRACH signal, SRS, UCI, and a target signal whose signal characteristics meet the second preset condition. For example, the first signaling includes a PRACH signal and a first target uplink resource implementation carrying PRACH signal configuration information.
In this embodiment, optionally, the PRACH signals include one or more PRACH signals;
the PRACH signals include one or more PRACH signals;
the preamble sequence of the PRACH signal is preset;
the transmission resource of the PRACH signal is preset;
the PRACH signal and the channel measurement related signal have a corresponding relation;
the PRACH signal is the PRACH signal of the target cell;
The PRACH signal is determined according to the configuration of the target cell and/or the target cell;
the configuration information of the PRACH and the channel measurement related signals have a corresponding relation;
the corresponding relation exists between the transmission resource of the PRACH signal and the channel measurement related signal;
the terminal identification marks of the PRACH signal and the reference signal have a corresponding relation;
and the receiving time of the PRACH signal and the reference signal has a corresponding relation.
Here, for the PRACH signal as the first signaling, if the current target cell is a plurality of cells, if the random access channel (Random Access Channel, RACH) resources or configuration information of the plurality of cells are identical, one preamble sequence and the same resource are used as the first signaling, and the first signaling sent to the plurality of cells, that is, the first signaling corresponding to the plurality of cells is identical; in case that the plurality of cells have overlapping RACH resources, a preamble sequence and the same resources are also used as the first signaling, and the first signaling sent to the plurality of cells, i.e., the first signaling corresponding to the plurality of cells is the same; in the case that there is a cell RACH resource or a configuration different from that of other cells in the plurality of cells, one preamble is used alone as a first signaling for a cell different from the other cells, and is transmitted to the cell. The preamble sequence may be a pre-defined (predefined) for activating or deactivating channel measurement related signals, such as a dedicated preamble sequence.
Meanwhile, in order to transmit PRACH signals to a plurality of cells, the UE needs to acquire configuration information of the PRACH signals of the plurality of cells, where the configuration information is optionally transmitted by a serving cell, or the UE listens to perform acquisition.
The SRS in this embodiment includes SRS for measurement and/or for positioning. Optionally, the SRS satisfies at least one of:
the base sequence of the SRS is generated according to a preset identifier, wherein the preset identifier comprises a cell ID, a public ID or a positioning ID;
the sequence of the SRS is preset;
the SRS has at least one symbol for activating or deactivating transmission of the channel measurement related signal;
the SRS carries indication information of activation or deactivation;
the SRS and the channel measurement related signals have a corresponding relation;
the SRS transmission resource is preset or dynamically scheduled;
the SRS transmission resource and the channel measurement related signal have a corresponding relation;
the configuration information of the SRS is preset or dynamically scheduled;
the configuration information of the SRS and the channel measurement related signals have a corresponding relation;
the SRS and the terminal identification mark of the reference signal have a corresponding relation;
And the sending time of the SRS and the reference signal has a corresponding relation.
Wherein, for SRS there is at least one symbol for activating or deactivating the transmission of the channel measurement related signal, it may be a specific symbol (such as the first symbol, a plurality of continuous or discontinuous symbols). For SRS carrying the activated or deactivated indication information, the indication information may be an identification identifier and/or 1bit information, so that the neighboring cell does not need blind detection or blind detection is reduced. For the SRS transmission resource, N3 symbols may be preset or dynamically scheduled. The configuration information of the SRS may be carried by N4 symbols that are preset or dynamically scheduled, where the configuration information may also be information that performs key protection or scrambling with an identification identifier or other security identifiers. For SRS that has a correspondence with the channel measurement related signal, the correspondence may represent, but is not limited to, an offset between the channel measurement related signal and the SRS, where the offset is X symbols or Y slots (slots), and of course, the offset may also be x+y×14 symbols. Similarly, for SRS in which there is a correspondence between transmission resources or configuration information and channel measurement related signals, the correspondence may also represent, but is not limited to, an offset of the two.
For example, the SRS generates a corresponding SRS signal only according to the activation identifier, and only carries activation or deactivation information; or the SRS carries configuration information of a first SRS (one of the SRS, such as an SRS for positioning), and both activates the SRS reception and notifies the configuration information of the first SRS.

For UCI carrying indication information of activation or deactivation, the indication information may be an identification (e.g., UE or reference signal identification that needs to be activated), and/or 1bit information. For UCI related to signaling format and carried information, in particular, the signaling format may be similar to physical uplink control channel (Physical Uplink Control Channel, PUCCH) format (format) 0 or 1, and only contains an activated or deactivated distinction; specific channel measurement related signal information activated or deactivated may be included similarly to PUCCH format2 or 3.

As such, the first signaling may use a particular wireless message management (Radio Information Management, RIM) signal. If the time domain position of the transmission resource of the target signal is fixed, the time domain position may be a boundary slot of time division multiplexing (Time Division Duplexing, TDD). And the candidate resource is a scheduled resource for the terminal. The third preset condition and the fourth preset condition are both combs consistent with the frequency domain offset, and of course, the third preset condition and the fourth preset condition may be other settings.
Specifically, for a target signal of the ZC sequence, the ZC cyclic shift indicates whether to activate or which channel measurement related signal to activate.

Here, the second signaling may be that the serving cell transmits to the neighbor cell or that the serving cell transmits to a location management device such as an LMF. Moreover, the second signaling is used to activate or deactivate the terminal to send the reference signal, or may be sent by the serving cell to the terminal. Thus, implementation of the second signaling includes, but is not limited to, at least one of a target signal whose signal characteristics satisfy the first preset condition, xn interface information, DCI, target downlink resource, LPPa or NRPPa information. Of course, the LMF may also send signaling to activate or deactivate terminals to send reference signals.
The target signal that can be used as the second signaling may be the same as the target signal that is used as the first signaling, that is, the first preset condition is the same as the second preset condition, so the limitation on the target signal that is used as the first signaling is also applicable to the target signal that is used as the second signaling. However, for the target signal as the second signaling, if there is a correspondence between the target signal and the channel measurement related signal, there is a correspondence between the configuration information and the channel measurement related signal, there is a correspondence between the transmission resource and the channel measurement related signal, or there is a limitation on other related channel measurement related signals, and at this time, the channel measurement related signal is the reference signal. And for the target signal as the second signaling, the candidate resource is a resource scheduled for the neighbor cell.

The target signal needs a larger delay, such as continuous 2-symbol transmission, using an extended Cyclic Prefix (CP), or using a smaller subcarrier spacing, considering the distance between neighboring cells. And 2 consecutive symbols may be transmitted by aggregating the CP of two symbols to the first symbol or by phase-consecutive between symbols. Considering the distance between adjacent cells, the target signal needs a larger path loss.

Here, the first target uplink resource may be solely used as the first signaling; the configuration information of the signal of the first signaling and/or the signal related to channel measurement can be transmitted by matching a specific uplink resource with the signal of the first signaling. The information carried by the first target uplink resource can be analyzed by the physical layer, and optionally, the information carried by the first target uplink resource and the receiving cell identifier (or the information of the preconfigured reference signal) are combined to determine the reference signal to be sent, and of course, the values of X and Y can also be determined.

Wherein the time domain information includes, but is not limited to: time domain position, period offset, transmission timing, repetition information.
If the first signaling, such as SSB (in addition to the primary synchronization signal (Primary Synchronization Signal, PSS) and secondary synchronization signal (Secondary Synchronization SignalSSS), carries physical broadcast channel (Physical Broadcast Channel, PBCH) information, the first signaling may use at least one symbol for activating or deactivating transport channel measurement related signals and/or carry indication information (e.g., identification, 1bit information) of activation or deactivation. In the first signaling, there are N5 symbols for transmitting signals, and N6 symbols carry configuration information. The configuration information may be information that is key protected or scrambled with an identification or other security identifier.
In this embodiment, the identification of the activation or deactivation transmission channel measurement related signal or the security key may be configured by the network side device, or by a location management device such as an LMF. The neighbor cells may be preconfigured from the network side, or preconfigured by the network, or combined with the configuration.
In addition, in this embodiment, the implementation of the first target uplink resource is also applicable to the target downlink resource, which is not described herein.
Further, optionally, the method further comprises:
and transmitting the configuration information of the channel measurement related signals through a second target uplink resource.
Here, the second target uplink resource is a resource for dedicated transmission of configuration information of the channel measurement related signal.
In this embodiment, the configuration information of the first signaling may be configured by the network side device or the LMF. Thus, optionally, the method further comprises:
receiving configuration information of the first signaling sent by a position management device or a network device; wherein the configuration information of the first signaling includes at least one of:

and the corresponding relation of the signal related to the channel measurement.
Here, the type of the first signaling may include a PRACH signal, a dedicated activation or deactivation signal (e.g., SRS, target signal), or other uplink signal (UCI, first target uplink resource signal), as known above. The correspondence with the channel measurement related signals may be: all of the first signaling is activated or deactivated, and the first signaling corresponds to a specific channel measurement related signal, respectively.
Of course, the configuration information corresponding to the second signaling, the PRACH signal, the SRS, the UCI, the first target uplink resource, etc. may be similar to the first signaling described above, and will not be described herein again.
It should be noted that, in the first signaling, the second signaling may determine the transmitted channel measurement related signal in combination with the second target uplink resource and/or the first target uplink resource, and the second signaling may also determine the transmitted channel measurement related signal in combination with the second target uplink resource or the target downlink resource.
In this embodiment, the reception timing of the optional reference signal may be related to the signaling (e.g., first signaling, second signaling) that is activated or deactivated, which may also be used for information exchange (e.g., successful activation).
Optionally, after receiving the first signaling, the target cell may perform feedback with respect to the first signaling, so after sending the first signaling to the target cell, the method further includes:
receiving first feedback information of the target cell; wherein the first feedback information is used to indicate at least one of:
whether the transmission of the channel measurement related signal is successfully activated or deactivated;
whether the first signaling was successfully received.
And the first feedback information received by the terminal indicates whether the transmission channel measurement related signal is successfully activated or deactivated and/or whether the first signaling is successfully received.
The first feedback information may be interacted through UU signaling, for example, sent in random access feedback (Rach access response, RAR), and the indication is performed through one or more bits of information of the RAR, where the information may use uplink grant UL grant, or Cell-radio network temporary identifier (C-RNTI) (all 0 or all 1), etc.; for another example, the first feedback information is random access preamble authentication (Random Access Preamble Identifier, RAPID), which is a preamble index obtained by the gNB when detecting the preamble, if the terminal finds that the received RAPID is the same as the index used when sending the preamble (if the preamble is location specific, then the reference signal is considered to be successfully activated), the corresponding RAR is considered to be successfully received, and its corresponding RAPID MAC sub-header is composed of three fields (E/T/RAPID).
The first feedback information may also determine whether to activate or deactivate the intended signal by detecting the received signal.
However, in the above embodiment, it is known that the serving cell may send the second signaling to the neighboring cell, and the neighboring cell may feed back information to the serving cell, such as X2 signaling interaction, or send signaling to the LMF, where the LMF collects feedback information of all relevant neighboring cells, and sends the neighboring cell with acknowledgement response ACK or the neighboring cell with negative response NACK to the serving cell. At this time, the feedback information of the neighbor cell also indicates whether the reception reference signal is successfully activated or deactivated and/or whether the second signaling is successfully received. The feedback information of the neighboring cell may implement the first feedback information described above, which is not described herein.
In addition, the cell receiving the first signaling and/or the second signaling may also feedback to the LMF: the cell informs the LMF of activating or deactivating the corresponding signal by the independent signaling exchange; and when the cell interacts with other signaling, carrying feedback information of the cell to the LMF, and informing the LMF that the cell activates or deactivates the corresponding signal. Specifically, the activated or deactivated signal ID, the activated or deactivated source device, etc. may be fed back.
In this embodiment, optionally, the target cell is determined by at least one of:
configuring a network side;

In addition, for the target cell, the target cell transmission channel measurement related signal may be activated or deactivated through the third signaling of the LMF in addition to the target cell transmission channel measurement related signal being activated or deactivated through the first signaling of the terminal. Thus, the target cell receives the third signaling of the LMF, which activates or deactivates the transport channel measurement related signal.
The third signaling is used for activating or deactivating the target cell to receive the reference signal when the target cell is a serving cell and a neighbor cell or the target cell is a neighbor cell, which is the same as the first signaling; and in the case that the target cell is a service cell, the third signaling is used for activating or deactivating the target cell to send the second signaling and receive the reference signal, and performing channel measurement.
Moreover, the target cell receives configuration information of the third signaling sent by the LMF; or sending the configuration information of the third signaling to the LMF. The configuration information of the third signaling includes at least one of:

and measuring the corresponding relation of the related signals with the transmission channel.
Thus, the configuration information of the third signaling is similar to that of the first signaling, and will not be described herein.
Optionally, the third signaling includes:
NRPPa information.
For the cell receiving the third signaling, information feedback can be performed to the LMF, and the cell informs the LMF of activating or deactivating the corresponding signal through separate signaling exchange; and when the cell interacts with other signaling, carrying feedback information of the cell to the LMF, and informing the LMF that the cell activates or deactivates the corresponding signal. Specifically, the activated or deactivated signal ID, the activated or deactivated source device, etc. may be fed back.
In this embodiment, the terminal will be able to activate the serving cell measurement reference signal and the neighbor cell measurement reference signal based on the first signaling or the third signaling for channel measurement.
The application of the method in different scenarios (taking the example of activating the measurement SRS) in the embodiment of the present application is described below with reference to the accompanying drawings:
scenario one, as shown in fig. 4, a location server (Location Based Services, LBS) sends a location request to the LMF, including latency, accuracy thresholds. Here, the LMF configures SRS configuration information, and transmits the SRS configuration information to the serving cell and the neighbor cell for measurement of the subsequent SRS. The LMF may also transmit SRS configuration information to the terminal for the subsequent terminal to transmit SRS. The terminal transmits SRS activation signaling (i.e., first signaling) to the serving cell and the neighbor cell, and activates the serving cell and the neighbor cell to measure SRS. In this way, the terminal can send SRS, and the serving cell and the neighbor cell measure SRS to complete channel measurement in positioning. The service cell and the neighbor cell can also obtain the reporting result of the terminal.
The serving cell and the neighbor cell can also send feedback information to the terminal after receiving the SRS activation signaling, and indicate information such as activation condition.
The LMF can also activate serving cell and neighbor cell measurement SRS through SRS configuration information including SRS activation signaling (i.e., third signaling).
In a second scenario, as shown in fig. 5, the terminal performs a location service request, where the request requires a low-latency and high-precision positioning. Here, the LMF configures SRS configuration information, and transmits the SRS configuration information to the serving cell and the neighbor cell for subsequent measurement of SRS. The terminal transmits a serving cell activation signaling (i.e., a first signaling) to the serving cell, activates the serving cell to measure the SRS and transmits an SRS activation signaling (i.e., a second signaling). The neighbor cell measures SRS based on the received SRS activation signaling. In this way, the terminal can send SRS, and the serving cell and the neighbor cell measure SRS to complete channel measurement in positioning. The service cell and the neighbor cell can also obtain the reporting result of the terminal.
The serving cell can also send an SRS activation signaling to the terminal, and inform the terminal to send the SRS in time. The neighbor cell can also send feedback information to the serving cell after receiving the SRS activation signaling, indicating information such as activation condition.
The LMF can also activate serving cell and neighbor cell measurement SRS through SRS configuration information including SRS activation signaling (i.e., third signaling).
In a third scenario, as shown in fig. 6, the terminal performs a location service request, and the request requires a positioning with low delay and high precision. Here, the LMF configures SRS configuration information, and transmits the SRS configuration information to the serving cell and the neighbor cell for subsequent measurement of SRS. The terminal transmits a serving cell activation signaling (i.e., a first signaling) to the serving cell, activates the serving cell to measure the SRS and transmits an LMF activation signaling (i.e., a second signaling). The LMF transmits SRS activation signaling to the neighbor cell based on the received LMF activation signaling. The neighbor cell measures SRS based on the received SRS activation signaling. In this way, the terminal can send SRS, and the serving cell and the neighbor cell measure SRS to complete channel measurement in positioning. The service cell and the neighbor cell can also obtain the reporting result of the terminal.
The serving cell can also send an SRS activation signaling to the terminal, and inform the terminal to send the SRS in time. The serving cell can also send configuration information of the SRS activation signaling so that the neighbor cell receives the SRS activation signaling. The neighbor cell can also send feedback information to the serving cell after receiving the SRS activation signaling, indicating information such as activation condition.
The LMF can also activate serving cell and neighbor cell measurement SRS through SRS configuration information including SRS activation signaling (i.e., third signaling).
And fourthly, the terminal performs a position service request, and the request needs positioning with low time delay and high precision. The terminal transmits a serving cell activation signaling (i.e., a first signaling) to the serving cell, activates the serving cell to measure the SRS and transmits an LMF activation signaling (i.e., a second signaling). The LMF transmits SRS activation signaling to the neighbor cell based on the received LMF activation signaling. The neighbor cell measures SRS based on the received SRS activation signaling. In this way, the terminal can send SRS, and the serving cell and the neighbor cell measure SRS to complete channel measurement in positioning.
Scene five, the location server (Location Based Services, LBS) sends a location request to the LMF, including latency, accuracy thresholds. Here, the LMF configures SRS configuration information, and transmits the SRS configuration information to the serving cell and the neighbor cell for subsequent measurement of SRS. The LMF may also transmit SRS configuration information to the terminal for the subsequent terminal to transmit SRS. The LMF transmits SRS configuration information of SRS activation signaling (i.e., third signaling) to activate serving cell and neighbor cell measurement SRS. The LMF or the serving cell transmits a second signaling to activate neighbor cell measurement SRS or the UE transmits SRS.
The optional LMF transmits the SRS in a fourth signaling activation.
In addition, the serving cell may send the LMF activation signaling to the LMF and simultaneously send the SRS activation signaling to the neighbor cell to activate the neighbor cell to measure the SRS.
In the above scenario, the configuration information may be interactively configured by the two-terminal device, e.g., the SRS configuration information may be configured by the serving cell and sent to the LMF.
In summary, according to the method of the embodiment of the present application, the terminal directly activates or deactivates the transmission channel measurement related signal of the target cell by sending the first signaling to the target cell, that is, the serving cell and/or the neighboring cell of the terminal, so as to reduce the time delay of positioning, and meet the timeliness requirement for acquiring the reference signal.
