[0039] First, some terms involved in the embodiments of this application are introduced as follows:

[0040] Introduction to Uu link PRS measurement:

[0041] In the 3GPP protocol, positioning technology is mainly implemented through the Uu link, such as obtaining information such as delay, angle, and energy based on the downlink positioning reference signal (DL PRS) and uplink positioning reference signal (UL SRS). For example, Table 1 shows the correspondence between the positioning methods supported by the Uu link PRS measurement, the reference signals, and the measurement quantities. Among them, the measurement behavior and indicators of the user end are important directions. According to the user's Radio Resource Control (RRC) state, it can be simply divided into RRC inactive state measurement and RRC connected state measurement, among which RRC connected state measurement can be further divided into gap-based and non-gapless measurement. Usually, the measurement time is defined separately according to different measurement quantities, and the measurement time under each measurement quantity is obtained by accumulating the measurement time of each frequency point to be measured.

[0042] Table 1

[0043] Taking the gap-based RSTD measurement in RRC connected state as an example, the total measurement time is the sum of the measurement time of each positioning frequency layer (PFL). The measurement time of each positioning frequency layer is proportional to the number of samples Nsample, the shared amplification factor CSSF, the receive beam scanning factor N RxBeam , effective measurement time unit T effect For calculations, please refer to the following formula. T available_PRS,i =LCM(T PRS,i ,MGRP i ).

[0044] The square brackets in the formula indicate rounding up.

[0045] CSSF is a shared scaling factor that takes into account PRS measurements and measurement objects based on measurement gaps. For example, if the terminal is also configured with two SSB-based multiple measurement objects (MOs), a CSSF of 3 will triple the measurement time.

[0046] ·N RxBeam The number of receive beams (Rx beams) that the terminal needs to traverse when measuring PRS, frequency range 1 (FR1) band N RxBeam =1, frequency range 2 (FR2) frequency band is N RxBeam=8 or determine the parameters of the receiving beam according to the capabilities reported by the terminal.

[0047] ·k multiTEG This is the scaling factor associated with the terminal's Rx Timing Error Group. When the Location Management Function (LMF) does not configure the terminal to use multiple Rx TEGs for a PRS measurement, this parameter defaults to 1. When the LMF configures the terminal to use N Rx TEGs for a PRS measurement, this parameter defaults to 1. TEG,i When there are multiple TEGs and the terminal does not support simultaneous measurement of multiple TEG groups, the value is N TEG,i ; When the LMF configuration terminal uses N for a PRS measurement TEG,i TEG and the terminal supports simultaneous measurement of k TEG,simul When there are TEG groups, the value is TEG is usually used for timing-based measurements, such as RSTD and Rx-Tx time difference. For RSRP, RSRPP, and angle measurements, TEG does not need to be considered.

[0048] ·K p This is a scaling factor related to the MG configuration: When concurrent gaps are configured, the gaps associated with PRS measurement may require the discarding of some gap occasions due to gap conflicts, etc. This scaling factor is the ratio of the total number of gap occasions in a specific window to the number of available gap occasions. This parameter is not considered when there are no concurrent gaps or when PRS is measured outside of the gaps.

[0049] · The maximum number of PRS resources configured in a time slot, N' is the number of PRS resources that the terminal can process in a time slot, the two are compared and rounded up. N′=2, then the scaling factor of this item=3.

[0050] ·L available_PRS is the length of the PRS resource in the gap (unit: ms), N is the terminal capability, which means that Nms of PRS can be processed per Tms. Similarly, the two are compared and rounded up, for example, L available_PRS =2ms, N=1ms,

[0051] ·T available_PRS,i =LCM(T PRS,i ,MGRP i) represents the least common multiple of the PRS period and the Measurement Gap Repetition Period (MGRP).

[0052] ·T last If all PRS resources to be tested are concentrated in one MG opportunity, then T last It is equal to MGL (the length of MG) plus the processing time T i , otherwise it is equal to T available_PRS Plus processing time T i .

[0053] N, T, this terminal capability indicates that the terminal can process Nms of PRS length in each Tms. T used in the above formula is i and N i It represents the capability corresponding to PFL#i.

[0054] Introduction to sideline communication:

[0055] In sideline communication (communication based on sideline links), according to the network coverage of the communicating terminals, it can be divided into three situations: sideline communication within network coverage, sideline communication with partial network coverage, and sideline communication outside network coverage.

[0056] For example, Figure 1 is a schematic diagram of network coverage inner row communication provided by an exemplary embodiment of the present application, Figure 2 is a schematic diagram of partial network coverage side row communication provided by an exemplary embodiment of the present application, and Figure 3 is a schematic diagram of network coverage outer row communication provided by an exemplary embodiment of the present application.

[0057] As shown in Figure 1, in the case of sideline communication within network coverage, all terminals performing sideline communication are within the coverage of the same base station. Therefore, the above terminals can all perform sideline communication based on the same sideline configuration by receiving configuration signaling from the base station, and the sideline configuration may include time-frequency resources for sideline communication.

[0058] As shown in Figure 2, in the case of partial network coverage for sidelink communication, the first part of the terminals performing sidelink communication are located within the coverage of the base station. The terminals in the first part can receive the configuration signaling from the base station, thereby performing sidelink communication according to the configuration of the base station. However, the second part of the terminals performing sidelink communication are located outside the network coverage, and the terminals in the second part cannot receive the configuration signaling from the base station. In this case, the terminals outside the network coverage will determine the sidelink configuration based on the pre-configuration information and the information carried in the Physical Sidelink Broadcast Channel (PSBCH) sent by the terminals within the network coverage, thereby performing sidelink communication.

[0059] As shown in Figure 3, in the case of sideline communication outside the network coverage, all terminals performing sideline communication are located outside the network coverage. All terminals performing sideline communication determine the sideline configuration according to the pre-configuration information to perform sideline communication.

[0060] Introduction to SL PRS and SL PRS measurement:

[0061] The design of the SL PRS may differ significantly from that of the Uu link PRS. SL PRS transmission may not follow a fixed period and time-frequency resource location like the Uu link PRS. Especially when the SL PRS uses scheme 2 resource allocation, the transmitter uses sensing-based and random selection to select the transmission resources used by the SL PRS. This results in a certain degree of uncertainty regarding the actual location (e.g., slot) of the transmitted SL PRS. For example, terminal A needs to transmit an SL PRS with a period of 10ms. The first transmission occurs in slot #0, and the second transmission is expected to occur in slot #10. However, no suitable resources are selected in slot #10, and the transmission may be postponed to slots #11 and #12. Similarly, the third transmission may occur around slot #20. Therefore, the actual SL PRS transmission period does not strictly adhere to the 10ms period.

[0062] The provisions for supporting SL PRS resource allocation are as follows:

[0063] ·Includes resource allocation scheme 1 (Scheme 1) and scheme 2 (Scheme 2), where scheme 1 corresponds to network-centric SL PRS resource allocation, and scheme 2 corresponds to terminal-autonomous SL PRS resource allocation.

[0064] For the resource allocation mechanism of SL PRS in solution 2:

[0065] Study and specify support for perception-based resource allocation and / or random resource selection;

[0066] Study and specify congestion control for SL PRS and / or inter-terminal coordination solutions for SL PRS.

[0067] Support resource allocation of the R16 / R17 / R18 sidelink communication shared resource pool and the SL PRS dedicated resource pool. For the SL positioning resource (pre-) configuration in the shared resource pool with R16 / R17 / R18 sidelink communication, backward compatibility with legacy R16 / R17 terminals should be ensured.

[0068] Related art mentions that SL-PRS supports Method 1 and its resource allocation method. Method 2 includes resource-aware and random resource selection methods. SL-PRS can be configured with a dedicated resource pool or shared with R16 / R17 / R18 sidelink communications.

[0069] The SL PFL is not defined in related technologies. The RS for SL positioning is defined directly relative to a single SL Band Width Part (BWP) and carrier, and is contained within that carrier. The SL PRS is equivalent to a single frequency point, eliminating the need for serial or parallel measurements of different PFLs. This means that the total measurement time does not need to be calculated by summing as in the Uu link. Furthermore, since the SL PRS is contained within the SL BWP and carrier, the receiver does not need to perform RF switching, and thus, does not require an MG.

[0070] Related technologies provide a method for calculating RSTD measurement time, which includes some parameters such as scaling factor, T last The measurement time of RSTD based on SL PRS is determined as follows:

[0071] The square brackets in the formula are ordinary square brackets.

[0072] S = scaling factor × N sample , the scaling factor needs to be studied in the future.

[0073] ·T effect,s =t s+1 -t s , t s Indicates the start of the time slot of the SL PRS that the terminal needs to measure for the sth time, t s+1 Indicates the start of the time slot of the SL PRS that the terminal needs to measure for the (s+1)th time.effect,s The conditions that need to be met are for future research.

[0074] ·T last This needs future research.

[0075] For N sample , further discussing the following two options:

[0076] Option 1: Define the sampling requirement as 1 and study 4 in the future.

[0077] Option 2: Define the sample size requirements as 1 and 4.

[0078] The measurement time of the SL PRS by the terminal may be related to the terminal capabilities. For example, Table 2 shows some relevant terminal capabilities.

[0079] Table 2

[0080] It should be noted that the processing time of component 4 in the above capability is calculated from the end of the time slot containing the PRS, and the activation time of the SL PRS resource is calculated from the last symbol of the PSCCH of the corresponding SCI.

[0081] For example, FIG4 is a schematic diagram of activating PRS provided by an exemplary embodiment of the present application. As shown in FIG4, starting from the end position of the time slot #n carrying the SL PRS, T proc Part is the processing time indicated by component 4, and then starting from the last symbol of the PSCCH corresponding to the SCI, the SL PRS is considered to be activated until the processing time ends.

[0082] For Rx-Tx time difference measurement of the terminal, the following capabilities shown in Table 3 are also supported.

[0083] Table 3

[0084] Unlike the time-frequency location of DL PRS (such as specific period, physical resource block (PRB) resources, etc.), which is pre-configured and predictable, the transmission method of SL PRS, like SL data, needs to be adjusted based on the terminal's channel monitoring results. In this case, the measurement time cannot be determined directly based on the PRS period, but the interval T between all adjacent SL PRSs is set to 1. effect and T lastThe related art only provides the calculation framework of SL PRS RSTD measurement time, and some parameters have not yet been finalized, such as the scaling factor, T last Taking into account the difference between the terminal measurement capability of SL PRS and DL PRS, the calculation formula of DL PRS measurement time cannot be directly used, so it is necessary to clarify the method of determining the relevant parameters. In addition, the SL RTT positioning solution also proposes a double-sided Rx-Tx time difference measurement solution to solve the problem of reducing the error caused by clock offset. This requires the user to send the results of measuring multiple Rx-Tx time differences to one SL PRS, and the measurement time also needs to be modified accordingly.

[0085] The method provided by the present application provides a solution for determining the measurement time of the sideline positioning reference signal based on the measurement capability of the terminal, including: (1) determining T according to the processing delay of the sideline terminal (corresponding to component 4 in Table 2) effect and T last ; (2) Determine S / scaling factor according to the maximum number of activated side positioning reference signal resources that the side terminal can measure (corresponding to component 2 in Table 2) and / or the maximum number of time domain units of activated side positioning reference signals that the side terminal can measure (corresponding to component 3 in Table 2); (3) Corresponding to Rx-Tx time difference measurement, further amplify the measurement time according to different measurement definitions (corresponding to Table 3) and the measurement configuration N of multiple Rx-Tx time differences. The above scheme can determine the measurement time of the side positioning reference signal, thereby providing an implementation method for determining the measurement time of the side positioning reference signal based on the measurement capability of the side terminal. And for side terminals with different measurement capabilities, the determined measurement time can be made consistent with their measurement capabilities.

[0086] 5 shows a schematic diagram of a system architecture of a communication system 500 provided in one embodiment of the present application. The system architecture may include: a terminal 10, an access network device 20, and a core network device 30.

[0087] The terminal 10 may refer to a UE (User Equipment), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user apparatus. Alternatively, the terminal may be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a 5GS (5th Generation System) or a terminal in a future-evolved PLMN (Public Land Mobile Network), etc., and the embodiments of the present application are not limited thereto. For convenience of description, the above-mentioned devices are collectively referred to as terminals.

[0088] It should be noted that there are usually multiple terminals 10. One or more terminals 10 can be distributed within each cell managed by the access network device 20. Furthermore, one or more terminals 10 can also be distributed outside the cell managed by the access network device 20. Different terminals 10 can communicate with each other based on sidelinks.

[0089] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal 10 are collectively referred to as access network equipment. Optionally, a communication relationship can be established between terminal 10 and core network equipment 30 through access network equipment 20. For example, in a Long Term Evolution (LTE) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in EUTRAN; in a 5G NR system, access network equipment 20 may be a RAN or one or more gNBs in the RAN.

[0090] The core network equipment 30 primarily provides user connectivity, user management, and service bearering, serving as a bearer network interface to external networks. For example, the core network equipment in a 5G NR system may include devices such as an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity. The access network equipment 20 and the core network equipment 30 may be collectively referred to as network equipment.

[0091] In one example, the access network device 20 and the core network device 30 communicate with each other via an air technology, such as the NG interface in a 5G NR system. The access network device 20 and the terminal 10 communicate with each other via an air technology, such as the Uu interface. The terminals 10 communicate with each other via an air technology, such as the PC5 interface.

[0092] FIG6 is a flow chart of a method for determining a measurement time provided by an exemplary embodiment of the present application. The method may be executed by a sideline terminal. The method includes:

[0093] Step 602: Determine measurement parameters according to the measurement capability of the sideline terminal.

[0094] A sidelink terminal includes a terminal that supports sidelink communication. The measurement parameter is used to determine the sidelink terminal's measurement time of a sidelink positioning reference signal. The measurement capability reflects the sidelink terminal's ability to measure the sidelink positioning reference signal, such as the related capabilities shown in Table 2 above. The sidelink positioning reference signal includes a reference signal used for positioning, transmitted via the sidelink, such as a Sidelink Positioning Reference Signal (SL PRS).

[0095] In some embodiments, depending on the measurement quantity (measurement method) of the sideways positioning reference signal, the determination of the measurement time can be divided into the following three determination methods.

[0096] For the first determination method:

[0097] In some embodiments, the sideways positioning reference signal measurement method corresponding to the first determination method includes at least one of the following:

[0098] RSTD measurement;

[0099] RTOA measurements;

[0100] RSRP measurement;

[0101] RSRPP measurement;

[0102] AOA measurement;

[0103] ZOA measurement;

[0104] Rx-Tx time difference measurement.

[0105] The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. For example, after receiving the SL PRS sent by the sideline terminal A, the sideline terminal B needs to send the SL PRS to the sideline terminal A to measure the single-sided RTT value. In some embodiments, the Rx-Tx time difference measurement includes two definitions: (1) the sideline terminal does not need to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference; (2) the sideline terminal needs to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference. In some embodiments, for the Rx-Tx time difference measurement, when it is not required to use the actual sideline positioning reference signal transmission time to determine the measurement result of the Rx-Tx time difference (Definition 1), that is, when it is not necessary to consider the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals, the first determination method can be used to determine the measurement time.

[0106] In some embodiments, the measured parameters include at least one of the following:

[0107] First parameter;

[0108] The second parameter;

[0109] The third parameter.

[0110] The first parameter is used to reflect the interval between the sth and s+1th measurements (receptions) of the sideline positioning reference signal by the sideline terminal, where s is a positive integer and not greater than S. The second parameter is used to reflect the time when the sideline terminal last measured the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0111] In some embodiments, the sideline terminal determines a first parameter of a sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time, for example, the time domain starting position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. The second time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the s+1th time, for example, the time domain starting position of the resource of the sideline positioning reference signal measured by the sideline terminal for the s+1th time. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. The first measurement capability is used to reflect the minimum processing time for the sideline terminal to receive the resource of the sideline positioning reference signal.

[0112] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0113] In some embodiments, if a sidelink positioning reference signal resource of the next period that belongs to the same sidelink positioning reference signal resource group as the sidelink positioning reference signal appears during the sidelink terminal's processing time for the sidelink positioning reference signal, the sidelink terminal will discard the sidelink positioning reference signal. In some embodiments, for sidelink positioning reference signals within a time domain unit (e.g., a slot), an identity document (ID) can be used to identify whether they belong to the same sidelink positioning reference signal resource. Multiple periodic sidelink positioning reference signal resources sent by the same sidelink terminal can be regarded as a sidelink positioning reference signal resource group / set.

[0114] In some embodiments, when the sideline terminal only needs to measure one sideline positioning reference signal resource group, T slprs,dur The time of a time domain unit (such as slot). If the measurement time is calculated in ms, a time slot of 15kHz corresponds to 1ms, that is, T slprs,dur=1ms.

[0115] In some embodiments, when the sideline terminal needs to measure multiple sideline positioning reference signal resource groups, Tslprs,dur is the total time span of the sideline positioning reference signal resources processed each time. slprs,dur The value of is the total time span of multiple sidelink positioning reference signal resources within each sampling period, each occasion, or each period. For example, it is the time span from the start of the first sidelink positioning reference signal resource's time slot to the end of the last sidelink positioning reference signal resource's time slot, including any unused time slots in between. Similarly, it can be converted to units such as milliseconds based on the number of time slots.

[0116] In some embodiments, the sideline terminal determines the second parameter based on the sum of a time span of a last measurement and a first measurement capability. The time span of the last measurement reflects the time span of the sideline positioning reference signal resource last measured by the sideline terminal, and the first measurement capability reflects the minimum processing time required for the sideline terminal to receive the sideline positioning reference signal resource.

[0117] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the sideline positioning reference signal resource measured by the sideline terminal for the last time / last period / Sth time. The determination method can refer to the relevant content above. proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0118] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0119] Number of samples;

[0120] Receive beam factor;

[0121] Timing error group factor;

[0122] Number of measurements;

[0123] Scaling factor

[0124] The sampling number reflects the number of sideline positioning reference signal samples taken by the sideline terminal, the receive beam factor reflects the number of receive beams traversed by the sideline terminal while measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the measurement number reflects the number of sideline positioning reference signal resources measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the sampling number.

[0125] For example, the number of samples is N sample , usually N sample =4 or 1, depending on the measurement capability of the sideline terminal. The receiving beam factor is N RxBeam For example, the side positioning reference signal supports FR2, then N RxBeam =8, or the receive beam sweeping factor parameter reported by the sideline terminal. The timing error group factor is k multiTEG , please refer to the above introduction to DL PRS. In some embodiments, N RxBeam and k multiTEG The determination of these two parameters may refer to DL PRS measurement. For example, the side positioning reference signal also supports FR2 or TEG function and may be used in DL PRS.

[0126] In some embodiments, the sideline terminal determines the scaling factor based on the configuration of the sideline positioning reference signal to be measured. For example, if the number of sideline positioning reference signal resources activated at a certain moment exceeds the measurement capability of the sideline terminal, or the number of time domain units (time slots) carrying activated sideline positioning reference signals at a certain moment exceeds the measurement capability of the sideline terminal, the measurement time needs to be further extended.

[0127] In some embodiments, the scaling factor is associated with at least one of a second measurement capability and a third measurement capability of the sideline terminal. The second measurement capability is used to reflect the maximum number of resources of activated sideline positioning reference signals that the sideline terminal supports processing (corresponding to component 2 in Table 2), and the third measurement capability is used to reflect the maximum number of time domain units carrying activated sideline positioning reference signals that the sideline terminal supports processing (corresponding to component 3 in Table 2). In some embodiments, the time domain unit includes a time slot. In some embodiments, the scaling factor includes at least one of a first scaling factor and a second scaling factor.

[0128] In some embodiments, the sideline terminal determines a first scaling factor based on a ratio of the first information and the second measurement capability to determine a third parameter. The first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure. For example, the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure is X_cfg, and the second measurement capability is X_ue. Assuming that all sideline positioning reference signals are activated simultaneously in the worst case, the first scaling factor S1 is related to (X_cfg / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1 = ceil(X_cfg / X_ue).

[0129] In some embodiments, the sideline terminal determines a first scaling factor based on the ratio of the second information and the second measurement capability to determine the third parameter. The second information includes the number of sideline positioning reference signal resources actually activated simultaneously or the maximum number of sideline positioning reference signal resources actually activated simultaneously. The number of resources activated simultaneously at different times may be different. For example, the sideline terminal is configured to measure 10 sideline positioning reference signal resources, but these 10 resources are relatively dispersed in the time domain, and the number actually activated simultaneously may be only 2. For example, the number of sideline positioning reference signal resources actually activated simultaneously is X_act, the maximum number of sideline positioning reference signal resources actually activated simultaneously is X_act=max(X_act,i), the second measurement capability is X_ue, and the first scaling factor S1 is related to (X_act / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1=ceil(X_act / X_ue).

[0130] In some embodiments, the sideline terminal determines a first scaling factor based on the ratio of the third information and the second measurement capability to determine the third parameter. The third information includes the minimum value of the first information and the fourth information, the first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure, the fourth information is determined based on the fifth information and the sixth information, the fifth information includes the number of time domain units corresponding to the first measurement capability, the sixth information includes the maximum number of resources of the sideline positioning reference signal configured on each time domain unit, and the first measurement capability is used to reflect the minimum processing time of the sideline terminal to receive the resources of the sideline positioning reference signal. For example, the third information is X_3=min(X_cfg, (Npro+second value)*K), K is the maximum number of resources of the sideline positioning reference signal configured on each time domain unit (time slot). Npro is the T of the sideline terminal. proc(ms) corresponds to the number of time slots. It is assumed here that the period of the side positioning reference signal is greater than the processing time of the side terminal, otherwise the resources of multiple periods of the same side positioning reference signal may be reproduced within the Npro processing delay. In some embodiments, the second value is 1, and the time slot in which the side positioning reference signal itself is located is considered. The first scaling factor is related to (X_3 / X_ue), for example, rounding up or rounding down (X_3 / X_ue), for example, S1=ceil(X_3 / X_ue).

[0131] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the seventh information and the third measurement capability to determine the third parameter. The seventh information is used to reflect the number of configured time domain units carrying sideline positioning reference signals, and the seventh information is equal to the first information. The first information includes the number of resources of the configured sideline positioning reference signals that the sideline terminal needs to measure. For example, according to the configuration, the number of time slots carrying sideline positioning reference signals can be determined as Y_cfg=X_cfg, and the third measurement capability is Y_ue, where Y_cfg assumes that in the worst case, all resources of the sideline positioning reference signals are dispersed in different time slots and activated at the same time. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, rounding up or rounding down (Y_cfg / Y_ue), for example, S2=ceil(Y_cfg / Y_ue).

[0132] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the eighth information and the third measurement capability to determine the third parameter. The eighth information includes the number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously or the maximum number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously. The number of resources activated simultaneously at different times may be different. For example, the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act, and the maximum value of the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act=max(Y_act,i). The second scaling factor S2 is related to (Y_act / Y_ue), for example, (Y_act / Y_ue) is rounded up or rounded down, for example, S2=ceil(Y_act / Y_ue).

[0133] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the ninth information and the third measurement capability to determine the third parameter. The ninth information includes the minimum value of the first information and the information determined based on the fifth information, the first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure, the fifth information includes the number of time domain units corresponding to the first measurement capability, and the first measurement capability is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal. For example, the number of time slots containing the sideline positioning reference signal (ninth information) determined according to the configuration is Y_cfg=min(X_cfg,Npro+1), and the third measurement capability is Y_ue. Y_cfg assumes that in the worst case, all the resources of the sideline positioning reference signal are scattered in different time slots and activated at the same time. Npro is the T of the sideline terminal. proc In some embodiments, the third value is 1. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, rounding up or down (Y_cfg / Y_ue), for example, S2 = ceil (Y_cfg / Y_ue).

[0134] In some embodiments, when the third measurement capability of the sideline terminal is not defined, or the third measurement capability is set to be large by default, it may be considered that S2=1.

[0135] In some embodiments, the first scaling factor and the second scaling factor may be multiplied by the number of samples and / or other scaling factors used to determine the third parameter to obtain the third parameter. For example, S = S1 × S2 × N sample ×k multiTEG ×N RxBeam , or S=ceil(S1×S2×N sample ×k multiTEG ×N RxBeam ), when calculating S1 or S2, you can calculate the final S without rounding up first, and multiply all scaling factors and then round up.

[0136] In some embodiments, if the periodicity of the sidelink positioning reference signal resources measured by the sidelink terminal is different, the above parameters may be determined based on the sidelink positioning reference signal resources with the maximum period.

[0137] In some embodiments, the third parameter is related to the number of sideline positioning reference signal resources measured by the sideline terminal, for example, S=measured number of SL PRS resources×N sample , at this time T effect Indicates the time interval between two adjacent sideline positioning reference signal resources.

[0138] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0139] Regarding the second determination method:

[0140] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes Rx-Tx time difference measurement. Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, Rx-Tx time difference measurement includes two definitions. In some embodiments, for Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the second determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes single-sided RTT measurement based on Rx-Tx time difference.

[0141] In some embodiments, the second determination method can be further divided into the following two determination methods.

[0142] For method 1:

[0143] In some embodiments, the measured parameters include at least one of the following:

[0144] First parameter;

[0145] The second parameter;

[0146] The third parameter.

[0147] The first parameter is used to reflect the interval between the sth and s+1th measurements of the sideline positioning reference signal by the sideline terminal, where s is a positive integer. The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0148] In some embodiments, the sideline terminal determines a first parameter of a sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. In some embodiments, the time domain position includes the time domain position of the resource for receiving and transmitting the sideline positioning reference signal corresponding to the sth measurement. The second time domain position is the time domain position of the resource for receiving and transmitting the sideline positioning reference signal measured by the sideline terminal for the s+1th time. In some embodiments, the time domain position includes the time domain position of the resource for receiving and transmitting the sideline positioning reference signal corresponding to the s+1th measurement. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. In some embodiments, the sideline positioning reference signal measured for the sth time includes the sideline positioning reference signal received and transmitted corresponding to the sth measurement. The first measurement capability includes receive processing time, or the maximum value of receive processing time and transmit processing time. The receive processing time reflects the minimum processing time required for a sideline terminal to receive a sideline positioning reference signal resource (corresponding to component 4 in Table 2), and the transmit processing time reflects the minimum processing time required for a sideline terminal to determine an Rx-Tx time difference based on the transmitted sideline positioning reference signal resource.

[0149] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0150] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability.

[0151] In some embodiments, method 1 is applicable to the situation where each sidelink positioning reference signal reception of the sidelink terminal corresponds to a sidelink positioning reference signal transmission, and / or the time when the sidelink terminal transmits the sidelink positioning reference signal is no later than the sidelink positioning reference signal reception of the next period.

[0152] In some embodiments, the sidelink terminal determines a second parameter based on the sum of the time span of the last measurement and the first measurement capability. The time span of the last measurement is used to reflect the time span of the resources of the sidelink positioning reference signal that the sidelink terminal last measured (received) and transmitted. The first measurement capability includes the reception processing time, or the maximum value of the reception processing time and the transmission processing time. The reception processing time is used to reflect the minimum processing time for the sidelink terminal to receive the resources of the sidelink positioning reference signal, and the transmission processing time is used to reflect the minimum processing time for the sidelink terminal to determine the Rx - Tx time difference based on the resources of the transmitted sidelink positioning reference signal.

[0153] Exemplarily, the above process can be expressed as: T last = T slprs,dur,S + T proc . Where, T last represents the second parameter, T slprs,dur,S represents the time span (duration) of the resources of the received and transmitted sidelink positioning reference signal of the sidelink terminal's last measurement / last cycle / the Sth measurement. T proc represents the first measurement capability. For example, if the sidelink terminal B receives the SL PRS of the last time slot in slot#n and transmits the SL PRS of the last time slot in slot#m, then T slprs,dur,S is from the start time of slot#n to the end time of slot#m, a total of (m - n + 1) time slots. In some embodiments, if the SL PRS for measuring the Rx - Tx time difference is transmitted before the SL PRS is received, that is, m < n, then T slprs,dur,S only needs to consider the duration of the received SL PRS. In this case, T slprs,dur,S is (n - m + 1) time slots. Reference can be made to the relevant content in the first determination method.

[0154] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0155] · The number of samples;

[0156] · The receive beam factor;

[0157] · The timing error group factor;

[0158] · The number of measurements;

[0159] · The scaling factor.

[0160] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG It should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0161] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0162] For method 2:

[0163] In some embodiments, the measured parameters include at least one of the following:

[0164] First parameter;

[0165] The second parameter;

[0166] The third parameter.

[0167] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0168] In some embodiments, the sideline terminal determines a first parameter of an adjacent sideline positioning reference signal based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of a resource of a previous sideline positioning reference signal among adjacent sideline positioning reference signals, where the previous sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The second time domain position is the time domain position of a resource of a subsequent sideline positioning reference signal among adjacent sideline positioning reference signals, where the subsequent sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The first condition is used to limit the position difference to be greater than the sum of a time span of a resource of a previous sideline positioning reference signal and a first measurement capability. The first measurement capability includes a reception processing time, a transmission processing time, or a maximum value of the reception processing time and the transmission processing time. Among them, the receiving processing time is used to reflect the minimum processing time of the sideline terminal for receiving the resources of the sideline positioning reference signal (corresponding to component 4 in Table 2), and the sending processing time is used to reflect the minimum processing time of the sideline terminal for determining the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0169] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0170] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T proc Indicates the first measurement capability.

[0171] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability. The time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or transmitted by the sideline terminal for the last time. The first measurement capability includes the receiving processing time, or the transmitting processing time, or the maximum value of the receiving processing time and the transmitting processing time. Among them, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the transmitting processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the transmitted sideline positioning reference signal. For example, the sideline terminal can determine whether to use the receiving processing time or the transmitting processing time based on whether the sideline positioning reference signal is actually received first and then transmitted or transmitted first and then received.

[0172] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0173] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0174] Number of samples;

[0175] Receive beam factor;

[0176] Timing error group factor;

[0177] Number of measurements;

[0178] Scaling factor;

[0179] Specify the coefficient.

[0180] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEGIt should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0181] In some embodiments, the specified coefficient is 2. For example, the third parameter is calculated as S=2×S1×S2×N sample ×k multiTEG ×N RxBeam , which can be regarded as a specified coefficient to amplify S by 2 times, that is, to amplify the number of measurements by 2 times, to reflect that the transmission and reception corresponding to the measurement of the sideline terminal will each correspond to a sideline positioning reference signal resource.

[0182] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0183] Regarding the third determination method:

[0184] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes Rx-Tx time difference measurement. The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, the Rx-Tx time difference measurement includes two definitions. In some embodiments, for the Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the third determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes a double-sided RTT measurement based on the Rx-Tx time difference. Bilateral RTT measurement can reduce the impact of frequency offset. High-layer signaling can configure / instruct the sidelink terminal to measure N Rx-Tx time differences for one sidelink positioning reference signal resource, such as one sidelink positioning reference signal reception + N sidelink positioning reference signal transmissions, or one sidelink positioning reference signal transmission + N sidelink positioning reference signal receptions.

[0185] In some embodiments, the third determination method can be further divided into the following two determination methods.

[0186] For method 1:

[0187] In some embodiments, the measured parameters include at least one of the following:

[0188] First parameter;

[0189] The second parameter;

[0190] The third parameter.

[0191] The first parameter is used to reflect the interval between the sth and s+1th measurements (receptions) of the sideline positioning reference signal by the sideline terminal, where s is a positive integer. The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0192] In some embodiments, the sideline terminal determines a first parameter for the sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the sideline positioning reference signal resource measured (received) by the sideline terminal for the sth time. The second time domain position is the time domain position of the sideline positioning reference signal resource measured (received) by the sideline terminal for the s+1th time. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time. The first measurement capability includes a receive processing time, or the maximum value of the receive processing time and the transmit processing time. The receive processing time is used to reflect the minimum processing time for the sideline terminal to receive the sideline positioning reference signal resource (corresponding to component 4 in Table 2), and the transmit processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resource of the transmitted sideline positioning reference signal.

[0193] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0194] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,sIndicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability.

[0195] In some embodiments, mode 1 is applicable to the situation where every N sidelink positioning reference signals received by the sidelink terminal corresponds to one sidelink positioning reference signal sent.

[0196] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement and the first measurement capability. The time span of the last measurement is used to reflect the time span of the resources of the sideline positioning reference signal last measured and sent by the sideline terminal, depending on whether the sideline terminal sends first and then receives the sideline positioning reference signal or receives first and then sends the sideline positioning reference signal. The first measurement capability includes the receiving processing time, or the maximum value of the receiving processing time and the sending processing time. The receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0197] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving and sending the sideline positioning reference signal of the sideline terminal in the last measurement / last cycle / Sth measurement, which depends on whether the sideline terminal sends the sideline positioning reference signal first and then receives it, or receives it first and then sends it. proc Indicates the first measurement capability.

[0198] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0199] Number of samples;

[0200] Receive beam factor;

[0201] Timing error group factor;

[0202] Number of measurements;

[0203] Scaling factor;

[0204] Configuration coefficient.

[0205] Among them, the number of samples is used to reflect the number of samples of the side positioning reference signal taken by the side terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the side terminal in the process of measuring the side positioning reference signal, the timing error group factor is related to the timing error group adopted by the side terminal to measure the side positioning reference signal, and the number of measurements is used to reflect the number of resources of the side positioning reference signal measured by the side terminal. The configuration coefficient includes the number of side positioning reference signals that the configured side terminal needs to measure for the transmission of the same side positioning reference signal, or the number of side positioning reference signals that the configured side terminal needs to send for the reception of the same side positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured side terminal needs to report. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0206] In some embodiments, the configuration coefficient is configured by high-level signaling. Considering that a sideline terminal may need to measure N sideline positioning reference signal resources when sending a sideline positioning reference signal resource, the third parameter S needs to be multiplied by N. For example, S = N × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0207] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0208] For method 2:

[0209] In some embodiments, the measured parameters include at least one of the following:

[0210] First parameter;

[0211] The second parameter;

[0212] The third parameter.

[0213] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0214] In some embodiments, the sideline terminal determines a first parameter of an adjacent sideline positioning reference signal based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of a resource of a previous sideline positioning reference signal among adjacent sideline positioning reference signals, where the previous sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The second time domain position is the time domain position of a resource of a subsequent sideline positioning reference signal among adjacent sideline positioning reference signals, where the subsequent sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The first condition is used to limit the position difference to be greater than the sum of a time span of a resource of a previous sideline positioning reference signal and a first measurement capability. The first measurement capability includes a reception processing time, a transmission processing time, or a maximum value of the reception processing time and the transmission processing time. Among them, the receiving processing time is used to reflect the minimum processing time of the sideline terminal for receiving the resources of the sideline positioning reference signal (corresponding to component 4 in Table 2), and the sending processing time is used to reflect the minimum processing time of the sideline terminal for determining the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0215] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0216] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t srepresents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T proc Indicates the first measurement capability.

[0217] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability. The time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or transmitted by the sideline terminal for the last time. The first measurement capability includes the receiving processing time, or the transmitting processing time, or the maximum value of the receiving processing time and the transmitting processing time. Among them, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the transmitting processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the transmitted sideline positioning reference signal. For example, the sideline terminal can determine whether to use the receiving processing time or the transmitting processing time based on whether the sideline positioning reference signal is actually received first and then transmitted or transmitted first and then received.

[0218] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0219] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0220] Number of samples;

[0221] Receive beam factor;

[0222] Timing error group factor;

[0223] Number of measurements;

[0224] Scaling factor;

[0225] Configuration coefficient + first value.

[0226] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group adopted by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. The configuration coefficient includes the number of sideline positioning reference signals that the configured sideline terminal needs to measure for the transmission of the same sideline positioning reference signal, or the number of sideline positioning reference signals that the configured sideline terminal needs to send for the reception of the same sideline positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured sideline terminal needs to report. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0227] In some embodiments, the configuration coefficient is configured by high-level signaling. In some embodiments, the first value is 1. Multiply S by (N+1), and the coefficient (N+1) is used to represent the total number of sideline positioning reference signal resources sent and received by the sideline terminal. For example, S = (N+1) × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0228] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0229] In summary, the method provided in this embodiment determines measurement parameters based on the measurement capabilities of a sideline terminal, and determines the measurement time of a sideline positioning reference signal based on the measurement parameters. This provides an implementation method for determining the measurement time of a sideline positioning reference signal based on the measurement capabilities of a sideline terminal. Furthermore, for sideline terminals with different measurement capabilities, the determined measurement time can be made consistent with their respective measurement capabilities.

[0230] The method provided in this application provides a solution for determining the measurement time of a side positioning reference signal based on the measurement capability of a terminal. The above solution can be used to determine the measurement time of a side positioning reference signal, thereby providing a method for determining the measurement time of a side positioning reference signal based on the measurement capability of a side terminal. Moreover, for side terminals with different measurement capabilities, the determined measurement time can be made consistent with their measurement capabilities. The determination of the measurement time can be generally divided into three determination methods:

[0231] For the first determination method:

[0232] FIG7 is a flow chart of a method for determining a measurement time provided by an exemplary embodiment of the present application. The method may be executed by a sideline terminal. The method includes:

[0233] Step 702: Determine measurement parameters using a first determination method according to the measurement capability of the sideline terminal.

[0234] A sidelink terminal includes a terminal that supports sidelink communication. The measurement parameter is used to determine the sidelink terminal's measurement time of a sidelink positioning reference signal. The measurement capability reflects the sidelink terminal's ability to measure the sidelink positioning reference signal, such as the related capabilities shown in Table 2 above. The sidelink positioning reference signal includes a reference signal used for positioning, transmitted via the sidelink, such as a Sidelink Positioning Reference Signal (SL PRS).

[0235] In some embodiments, the sideways positioning reference signal measurement method corresponding to the first determination method includes at least one of the following:

[0236] RSTD measurement;

[0237] RTOA measurements;

[0238] RSRP measurement;

[0239] RSRPP measurement;

[0240] AOA measurement;

[0241] ZOA measurement;

[0242] Rx-Tx time difference measurement.

[0243] The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. For example, after receiving the SL PRS sent by the sideline terminal A, the sideline terminal B needs to send the SL PRS to the sideline terminal A to measure the single-sided RTT value. In some embodiments, the Rx-Tx time difference measurement includes two definitions: (1) the sideline terminal does not need to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference; (2) the sideline terminal needs to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference. In some embodiments, for the Rx-Tx time difference measurement, when it is not required to use the actual sideline positioning reference signal transmission time to determine the measurement result of the Rx-Tx time difference (Definition 1), that is, when it is not necessary to consider the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals, the first determination method can be used to determine the measurement time.

[0244] In some embodiments, the measured parameters include at least one of the following:

[0245] First parameter;

[0246] The second parameter;

[0247] The third parameter.

[0248] The first parameter is used to reflect the interval between the sth and s+1th measurements (receptions) of the sideline positioning reference signal by the sideline terminal, where s is a positive integer and not greater than S. The second parameter is used to reflect the time when the sideline terminal last measured the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0249] In some embodiments, the sideline terminal determines a first parameter of a sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time, for example, the time domain starting position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. The second time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the s+1th time, for example, the time domain starting position of the resource of the sideline positioning reference signal measured by the sideline terminal for the s+1th time. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. The first measurement capability is used to reflect the minimum processing time for the sideline terminal to receive the resource of the sideline positioning reference signal.

[0250] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0251] In some embodiments, if during the processing time of the sidelink positioning reference signal by the sidelink terminal, a sidelink positioning reference signal resource of the next period belonging to the same sidelink positioning reference signal resource group as the sidelink positioning reference signal appears, the sidelink terminal will discard the sidelink positioning reference signal.

[0252] For example, Figure 8 is a schematic diagram of SL PRS resources provided by an exemplary embodiment of the present application. As shown in Figure 8, since SL PRS#2 is within the processing time of SL PRS#1, the sideline terminal will discard SL PRS#2 until the SL PRS at time t2 can be used as the new SL PRS#2. effect It is calculated based on the actual measured / not discarded SL PRS.

[0253] In some embodiments, the sideline terminal determines the second parameter based on the sum of a time span of a last measurement and a first measurement capability. The time span of the last measurement reflects the time span of the sideline positioning reference signal resource last measured by the sideline terminal, and the first measurement capability reflects the minimum processing time required for the sideline terminal to receive the sideline positioning reference signal resource.

[0254] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the sideline positioning reference signal resource measured by the sideline terminal for the last time / last period / Sth time. The determination method can refer to the relevant content above. proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0255] For example, FIG9 is a schematic diagram of SL PRS resources provided by an exemplary embodiment of the present application. As shown in FIG9, T slprs,dur,S Indicates the length of the SL PRS resources of the last S measurement / cycle that needs to be measured, including the empty time slots between SL PRSs. In the figure, SL PRS#4-1 is slot#10, SL PRS#4-2 is slot#14, then T slprs,dur,S The length is 5 slots.

[0256] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0257] Number of samples;

[0258] Receive beam factor;

[0259] Timing error group factor;

[0260] Number of measurements;

[0261] Scaling factor

[0262] The sampling number reflects the number of sideline positioning reference signal samples taken by the sideline terminal, the receive beam factor reflects the number of receive beams traversed by the sideline terminal while measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the measurement number reflects the number of sideline positioning reference signal resources measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the sampling number.

[0263] For example, the number of samples is N sample , usually N sample =4 or 1, depending on the measurement capability of the sideline terminal. The receiving beam factor is N RxBeam For example, the side positioning reference signal supports FR2, then N RxBeam =8, or the receive beam sweeping factor parameter reported by the sideline terminal. The timing error group factor is k multiTEG , please refer to the above introduction to DL PRS. In some embodiments, N RxBeam and k multiTEG The determination of these two parameters may refer to DL PRS measurement. For example, the side positioning reference signal also supports FR2 or TEG function and may be used in DL PRS.

[0264] In some embodiments, the sideline terminal determines the scaling factor based on the configuration of the sideline positioning reference signal to be measured. For example, if the number of sideline positioning reference signal resources activated at a certain moment exceeds the measurement capability of the sideline terminal, or the number of time domain units (time slots) carrying activated sideline positioning reference signals at a certain moment exceeds the measurement capability of the sideline terminal, the measurement time needs to be further extended.

[0265] In some embodiments, the scaling factor is associated with at least one of a second measurement capability and a third measurement capability of the sideline terminal. The second measurement capability is used to reflect the maximum number of resources of activated sideline positioning reference signals that the sideline terminal supports processing (corresponding to component 2 in Table 2), and the third measurement capability is used to reflect the maximum number of time domain units carrying activated sideline positioning reference signals that the sideline terminal supports processing (corresponding to component 3 in Table 2). In some embodiments, the time domain unit includes a time slot. In some embodiments, the scaling factor includes at least one of a first scaling factor and a second scaling factor.

[0266] In some embodiments, the sideline terminal determines a first scaling factor based on a ratio of the first information and the second measurement capability to determine a third parameter. The first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure. For example, the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure is X_cfg, and the second measurement capability is X_ue. Assuming that all sideline positioning reference signals are activated simultaneously in the worst case, the first scaling factor S1 is related to (X_cfg / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1 = ceil(X_cfg / X_ue).

[0267] In some embodiments, the sideline terminal determines a first scaling factor based on the ratio of the second information and the second measurement capability to determine the third parameter. The second information includes the number of sideline positioning reference signal resources actually activated simultaneously or the maximum number of sideline positioning reference signal resources actually activated simultaneously. The number of resources activated simultaneously at different times may be different. For example, the sideline terminal is configured to measure 10 sideline positioning reference signal resources, but these 10 resources are relatively dispersed in the time domain, and the number actually activated simultaneously may be only 2. For example, the number of sideline positioning reference signal resources actually activated simultaneously is X_act, the maximum number of sideline positioning reference signal resources actually activated simultaneously is X_act=max(X_act,i), the second measurement capability is X_ue, and the first scaling factor S1 is related to (X_act / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1=ceil(X_act / X_ue).

[0268] In some embodiments, the sideline terminal determines a first scaling factor based on the ratio of the third information and the second measurement capability to determine the third parameter. The third information includes the minimum value of the first information and the fourth information, the first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure, the fourth information is determined based on the fifth information and the sixth information, the fifth information includes the number of time domain units corresponding to the first measurement capability, the sixth information includes the maximum number of resources of the sideline positioning reference signal configured on each time domain unit, and the first measurement capability is used to reflect the minimum processing time of the sideline terminal to receive the resources of the sideline positioning reference signal. For example, the third information is X_3=min(X_cfg, (Npro+second value)*K), K is the maximum number of resources of the sideline positioning reference signal configured on each time domain unit (time slot). Npro is the T of the sideline terminal. proc (ms) corresponds to the number of time slots. It is assumed here that the period of the side positioning reference signal is greater than the processing time of the side terminal, otherwise the resources of multiple periods of the same side positioning reference signal may be reproduced within the Npro processing delay. In some embodiments, the second value is 1, and the time slot in which the side positioning reference signal itself is located is considered. The first scaling factor is related to (X_3 / X_ue), for example, rounding up or rounding down (X_3 / X_ue), for example, S1=ceil(X_3 / X_ue).

[0269] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the seventh information and the third measurement capability to determine the third parameter. The seventh information is used to reflect the number of configured time domain units carrying sideline positioning reference signals, and the seventh information is equal to the first information. The first information includes the number of resources of the configured sideline positioning reference signals that the sideline terminal needs to measure. For example, according to the configuration, the number of time slots carrying sideline positioning reference signals can be determined as Y_cfg=X_cfg, and the third measurement capability is Y_ue, where Y_cfg assumes that in the worst case, all resources of the sideline positioning reference signals are dispersed in different time slots and activated at the same time. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, rounding up or rounding down (Y_cfg / Y_ue), for example, S2=ceil(Y_cfg / Y_ue).

[0270] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the eighth information and the third measurement capability to determine the third parameter. The eighth information includes the number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously or the maximum number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously. The number of resources activated simultaneously at different times may be different. For example, the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act, and the maximum value of the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act=max(Y_act,i). The second scaling factor S2 is related to (Y_act / Y_ue), for example, (Y_act / Y_ue) is rounded up or rounded down, for example, S2=ceil(Y_act / Y_ue).

[0271] In some embodiments, the sideline terminal determines a second scaling factor based on the ratio of the ninth information and the third measurement capability to determine the third parameter. The ninth information includes the minimum value of the first information and the information determined based on the fifth information, the first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure, the fifth information includes the number of time domain units corresponding to the first measurement capability, and the first measurement capability is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal. For example, the number of time slots containing the sideline positioning reference signal (ninth information) determined according to the configuration is Y_cfg=min(X_cfg,Npro+1), and the third measurement capability is Y_ue. Y_cfg assumes that in the worst case, all the resources of the sideline positioning reference signal are scattered in different time slots and activated at the same time. Npro is the T of the sideline terminal. proc In some embodiments, the third value is 1. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, rounding up or down (Y_cfg / Y_ue), for example, S2 = ceil (Y_cfg / Y_ue).

[0272] In some embodiments, when the third measurement capability of the sideline terminal is not defined, or the third measurement capability is set to be large by default, it may be considered that S2=1.

[0273] In some embodiments, the first scaling factor and the second scaling factor may be multiplied by the number of samples and / or other scaling factors used to determine the third parameter to obtain the third parameter. For example, S = S1 × S2 × N sample ×k multiTEG ×N RxBeam , or S=ceil(S1×S2×N sample ×k multiTEG ×N RxBeam), when calculating S1 or S2, you can calculate the final S without rounding up first, and multiply all scaling factors and then round up.

[0274] In some embodiments, if the periodicity of the sidelink positioning reference signal resources measured by the sidelink terminal is different, the above parameters may be determined based on the sidelink positioning reference signal resources with the maximum period.

[0275] In some embodiments, the third parameter is related to the number of sideline positioning reference signal resources measured by the sideline terminal, for example, S=measured number of SL PRS resources×N sample , at this time T effect Indicates the time interval between two adjacent sideline positioning reference signal resources.

[0276] For example, FIG10 is a schematic diagram of SL PRS resources provided by an exemplary embodiment of the present application. As shown in FIG10 , when S is related to the number of SL PRS resources measured by the sideline terminal, T effect It is the time interval between two adjacent SL PRS resources, and there is no need to distinguish SL PRS resource groups.

[0277] T slprs,dur,S Indicates the length of the SL PRS resources of the last S measurement / cycle that needs to be measured, including the empty time slots between SL PRSs. In the figure, SL PRS#4-1 is slot#10, SL PRS#4-2 is slot#14, then T slprs,dur,S The length is 5 slots.

[0278] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0279] For example, continuing to refer to FIG8 , taking one SL PRS resource and S=4 as an example, T effect is the interval between two adjacent SL PRS measurements, and the total measurement time is T effect The sum plus T last .

[0280] The steps mentioned in the above embodiments can be implemented as independent embodiments, such as the step of determining the first parameter, the step of determining the second parameter and the step of determining the third parameter, which can be implemented separately as a measurement parameter determination method on the sideline terminal side.

[0281] In summary, the method provided in this embodiment determines measurement parameters based on the measurement capabilities of a sideline terminal, and determines the measurement time of a sideline positioning reference signal based on the measurement parameters. This provides an implementation method for determining the measurement time of a sideline positioning reference signal based on the measurement capabilities of a sideline terminal. Furthermore, for sideline terminals with different measurement capabilities, the determined measurement time can be made consistent with their respective measurement capabilities.

[0282] The method provided in this embodiment also determines the first, second, and third parameters based on the measurement capabilities, thereby determining the parameters used to calculate the measurement time based on the measurement capabilities, making the calculation process more consistent with the terminal's measurement capabilities. Furthermore, the method provided in this embodiment also provides methods for determining the first, second, and third parameters. By determining the scaling factor of the third parameter in conjunction with the sideline terminal's measurement capabilities, a more reasonable measurement time can be determined. Determining the first scaling factor based on the configured number of sideline positioning reference signal resources and the sideline terminal's capabilities provides a simple and direct method for calculating the first scaling factor based on the configuration. Determining the first scaling factor based on the actual number of activated sideline positioning reference signal resources and the sideline terminal's capabilities can, to a certain extent, avoid excessively extending the measurement time. Determining the first scaling factor based on third information and the sideline terminal's measurement capabilities increases flexibility in determining the first scaling factor. Determining the second scaling factor based on the configured number of sideline positioning reference signal resources and the sideline terminal's capabilities provides a simple and direct method for calculating the first scaling factor based on the configuration. Determining the second scaling factor based on the actual number of activated sideline positioning reference signal resources and the sideline terminal's capabilities can, to a certain extent, avoid excessively extending the measurement time. The second scaling factor is determined according to the ninth information and the measurement capability of the sideline terminal, thereby improving the flexibility of determining the second scaling factor.

[0283] Regarding the second determination method:

[0284] FIG11 is a flow chart of a method for determining a measurement time provided by an exemplary embodiment of the present application. The method may be executed by a sideline terminal. The method includes:

[0285] Step 1102: Determine the measurement parameters using the second determination method according to the measurement capability of the sideline terminal.

[0286] A sidelink terminal includes a terminal that supports sidelink communication. The measurement parameter is used to determine the sidelink terminal's measurement time of a sidelink positioning reference signal. The measurement capability reflects the sidelink terminal's ability to measure the sidelink positioning reference signal, such as the related capabilities shown in Table 2 above. The sidelink positioning reference signal includes a reference signal used for positioning, transmitted via the sidelink, such as a Sidelink Positioning Reference Signal (SL PRS).

[0287] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes Rx-Tx time difference measurement. Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, Rx-Tx time difference measurement includes two definitions. In some embodiments, for Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the second determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes single-sided RTT measurement based on Rx-Tx time difference.

[0288] For example, Figure 12 is a schematic diagram of a unilateral RTT measurement provided by an exemplary embodiment of the present application. As shown in Figure 12, for each of sideline terminals A and B, only one SL PRS received signal needs to be measured. The Rx-Tx time difference of sideline terminal A is time difference Ra, the Rx-Tx time difference of sideline terminal B is time difference Rb, and the transmission time of the SL PRS is Tf.

[0289] In some embodiments, the second determination method can be further divided into the following two determination methods.

[0290] For method 1:

[0291] In some embodiments, the measured parameters include at least one of the following:

[0292] First parameter;

[0293] The second parameter;

[0294] The third parameter.

[0295] The first parameter is used to reflect the interval between the sth and s+1th measurements of the sideline positioning reference signal by the sideline terminal, where s is a positive integer. The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0296] In some embodiments, the sideline terminal determines a first parameter of a sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. In some embodiments, the time domain position includes the time domain position of the resource for receiving and transmitting the sideline positioning reference signal corresponding to the sth measurement. The second time domain position is the time domain position of the resource for receiving and transmitting the sideline positioning reference signal measured by the sideline terminal for the s+1th time. In some embodiments, the time domain position includes the time domain position of the resource for receiving and transmitting the sideline positioning reference signal corresponding to the s+1th measurement. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the resource of the sideline positioning reference signal measured by the sideline terminal for the sth time. In some embodiments, the sideline positioning reference signal measured for the sth time includes the sideline positioning reference signal received and transmitted corresponding to the sth measurement. The first measurement capability includes receive processing time, or the maximum value of receive processing time and transmit processing time. The receive processing time reflects the minimum processing time required for a sideline terminal to receive a sideline positioning reference signal resource (corresponding to component 4 in Table 2), and the transmit processing time reflects the minimum processing time required for a sideline terminal to determine an Rx-Tx time difference based on the transmitted sideline positioning reference signal resource.

[0297] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0298] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability.

[0299] In some embodiments, method 1 is applicable to the situation where each sidelink positioning reference signal reception of the sidelink terminal corresponds to a sidelink positioning reference signal transmission, and / or the time when the sidelink terminal transmits the sidelink positioning reference signal is no later than the sidelink positioning reference signal reception of the next period.

[0300] In some embodiments, the sidelink terminal determines a second parameter based on the sum of the time span of the last measurement and the first measurement capability. The time span of the last measurement is used to reflect the time span of the resources of the sidelink positioning reference signal for the last measurement (reception) and transmission by the sidelink terminal. The first measurement capability includes the reception processing time, or the maximum value of the reception processing time and the transmission processing time. The reception processing time is used to reflect the minimum processing time for the sidelink terminal to receive the resources of the sidelink positioning reference signal, and the transmission processing time is used to reflect the minimum processing time for the sidelink terminal to determine the Rx-Tx time difference based on the resources of the transmitted sidelink positioning reference signal.

[0301] Exemplarily, the above process can be expressed as: T last = T slprs,dur,S + T proc . Where, T last represents the second parameter, and T slprs,dur,S represents the time span (duration) of the resources of the received and transmitted sidelink positioning reference signal for the last measurement / last cycle / S-th measurement of the sidelink terminal. T proc represents the first measurement capability. For example, if the sidelink terminal B receives the SL PRS of the last time slot in slot#n and transmits the SL PRS of the last time slot in slot#m, then T slprs,dur,S is from the start time of slot#n to the end time of slot#m, a total of (m - n + 1) time slots. In some embodiments, if the SL PRS for measuring the Rx-Tx time difference is transmitted before the SL PRS reception, that is, m < n, then T slprs,dur,S only needs to consider the duration of the received SL PRS. In this case, T slprs,dur,S is (n - m + 1) time slots. Reference can be made to the relevant content in the first determination method.

[0302] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0303] · The number of samples;

[0304] · The reception beam factor; <s <00q01138>· The timing error group factor; <00m01139>

[0306] A· The number of measurements;

[0307] · The scaling factor.

[0308] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG It should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0309] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0310] For method 2:

[0311] In some embodiments, the measured parameters include at least one of the following:

[0312] First parameter;

[0313] The second parameter;

[0314] The third parameter.

[0315] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0316] In some embodiments, the sideline terminal determines a first parameter of an adjacent sideline positioning reference signal based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of a resource of a previous sideline positioning reference signal among adjacent sideline positioning reference signals, where the previous sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The second time domain position is the time domain position of a resource of a subsequent sideline positioning reference signal among adjacent sideline positioning reference signals, where the subsequent sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The first condition is used to limit the position difference to be greater than the sum of a time span of a resource of a previous sideline positioning reference signal and a first measurement capability. The first measurement capability includes a reception processing time, a transmission processing time, or a maximum value of the reception processing time and the transmission processing time. Among them, the receiving processing time is used to reflect the minimum processing time of the sideline terminal for receiving the resources of the sideline positioning reference signal (corresponding to component 4 in Table 2), and the sending processing time is used to reflect the minimum processing time of the sideline terminal for determining the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0317] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0318] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T proc Indicates the first measurement capability.

[0319] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability. The time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or transmitted by the sideline terminal for the last time. The first measurement capability includes the receiving processing time, or the transmitting processing time, or the maximum value of the receiving processing time and the transmitting processing time. Among them, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the transmitting processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the transmitted sideline positioning reference signal. For example, the sideline terminal can determine whether to use the receiving processing time or the transmitting processing time based on whether the sideline positioning reference signal is actually received first and then transmitted or transmitted first and then received.

[0320] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0321] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0322] Number of samples;

[0323] Receive beam factor;

[0324] Timing error group factor;

[0325] Number of measurements;

[0326] Scaling factor;

[0327] Specify the coefficient.

[0328] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEGIt should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0329] In some embodiments, the specified coefficient is 2. For example, the third parameter is calculated as S=2×S1×S2×N sample ×k multiTEG ×N RxBeam , which can be regarded as a specified coefficient to amplify S by 2 times, that is, to amplify the number of measurements by 2 times, to reflect that the transmission and reception corresponding to the measurement of the sideline terminal will each correspond to a sideline positioning reference signal resource.

[0330] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0331] The steps mentioned in the above embodiments can be implemented as independent embodiments, such as the step of determining the first parameter, the step of determining the second parameter and the step of determining the third parameter, which can be implemented separately as a measurement parameter determination method on the sideline terminal side.

[0332] In summary, the method provided in this embodiment determines measurement parameters based on the measurement capabilities of a sideline terminal, and determines the measurement time of a sideline positioning reference signal based on these measurement parameters. This provides an implementation method for determining the measurement time of a unilateral RTT based on the Rx-Tx time difference based on the measurement capabilities of the sideline terminal. Furthermore, for sideline terminals with different measurement capabilities, the determined measurement time can be made consistent with their respective measurement capabilities.

[0333] The method provided in this embodiment also determines the first, second, and third parameters based on the measurement capabilities, thereby determining the parameters used to calculate the measurement time based on the measurement capabilities, making the calculation process more consistent with the terminal's measurement capabilities. Furthermore, the method provided in this embodiment also provides methods for determining the first, second, and third parameters. By determining the scaling factor of the third parameter based on the measurement capabilities of the sideline terminal, a more reasonable measurement time can be determined.

[0334] Regarding the third determination method:

[0335] FIG13 is a flow chart of a method for determining a measurement time provided by an exemplary embodiment of the present application. The method may be executed by a sideline terminal. The method includes:

[0336] Step 1302: Determine the measurement parameters using the third determination method according to the measurement capability of the sideline terminal.

[0337] A sidelink terminal includes a terminal that supports sidelink communication. The measurement parameter is used to determine the sidelink terminal's measurement time of a sidelink positioning reference signal. The measurement capability reflects the sidelink terminal's ability to measure the sidelink positioning reference signal, such as the related capabilities shown in Table 2 above. The sidelink positioning reference signal includes a reference signal used for positioning, transmitted via the sidelink, such as a Sidelink Positioning Reference Signal (SL PRS).

[0338] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes Rx-Tx time difference measurement. The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, the Rx-Tx time difference measurement includes two definitions. In some embodiments, for the Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the third determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes a double-sided RTT measurement based on the Rx-Tx time difference. Bilateral RTT measurement can reduce the impact of frequency offset. High-layer signaling can configure / instruct the sidelink terminal to measure N Rx-Tx time differences for one sidelink positioning reference signal resource, such as one sidelink positioning reference signal reception + N sidelink positioning reference signal transmissions, or one sidelink positioning reference signal transmission + N sidelink positioning reference signal receptions.

[0339] For example, Figure 14 is a schematic diagram of bilateral RTT measurement provided by an exemplary embodiment of the present application. As shown in Figure 14, for sideline terminal B, its SL PRS B transmission will correspond to two SL PRS receptions, namely SL PRS A1 and SL PRS A2, and N = 2 Rx-Tx time difference measurement results can be reported. For device A, its SL PRS B reception will correspond to two SL PRS transmissions, namely SL PRS A1 and SL PRS A2, and N = 2 Rx-Tx time difference measurement results can also be reported. For example, Figure 15 is a schematic diagram of bilateral RTT measurement provided by an exemplary embodiment of the present application. As shown in Figure 15, the difference between Figure 15 and Figure 14 is that N = 3. It should be noted that there is no restriction on the order of SL PRS A1, SL PRS A2, SL PRS A3, and SL PRS B here, that is, SL PRS B can be before SL PRS A1 or after SL PRS A3, and both are supported.

[0340] The Rx-Tx time difference of the sideline terminal A is the time difference Ra, Da, the Rx-Tx time difference of the sideline terminal B is the time difference Db, Rb, and the transmission time of the SL PRS is Tf.

[0341] In some embodiments, the third determination method can be further divided into the following two determination methods.

[0342] For method 1:

[0343] In some embodiments, the measured parameters include at least one of the following:

[0344] First parameter;

[0345] The second parameter;

[0346] The third parameter.

[0347] The first parameter is used to reflect the interval between the sth and s+1th measurements (receptions) of the sideline positioning reference signal by the sideline terminal, where s is a positive integer. The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0348] In some embodiments, the sideline terminal determines a first parameter for the sideline positioning reference signal measured by the sideline terminal for the sth time based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of the sideline positioning reference signal resource measured (received) by the sideline terminal for the sth time. The second time domain position is the time domain position of the sideline positioning reference signal resource measured (received) by the sideline terminal for the s+1th time. The first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability. The time span of the sth measurement is used to reflect the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time. The first measurement capability includes a receive processing time, or the maximum value of the receive processing time and the transmit processing time. The receive processing time is used to reflect the minimum processing time for the sideline terminal to receive the sideline positioning reference signal resource (corresponding to component 4 in Table 2), and the transmit processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resource of the transmitted sideline positioning reference signal.

[0349] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0350] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability.

[0351] In some embodiments, mode 1 is applicable to the situation where every N sidelink positioning reference signals received by the sidelink terminal corresponds to one sidelink positioning reference signal sent.

[0352] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement and the first measurement capability. The time span of the last measurement is used to reflect the time span of the resources of the sideline positioning reference signal last measured and sent by the sideline terminal, depending on whether the sideline terminal sends first and then receives the sideline positioning reference signal or receives first and then sends the sideline positioning reference signal. The first measurement capability includes the receiving processing time, or the maximum value of the receiving processing time and the sending processing time. The receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0353] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving and sending the sideline positioning reference signal of the sideline terminal in the last measurement / last cycle / Sth measurement, depending on whether the sideline terminal sends the sideline positioning reference signal first and then receives it, or receives it first and then sends it. proc Indicates the first measurement capability.

[0354] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0355] Number of samples;

[0356] Receive beam factor;

[0357] Timing error group factor;

[0358] Number of measurements;

[0359] Scaling factor;

[0360] Configuration coefficient.

[0361] Among them, the number of samples is used to reflect the number of samples of the side positioning reference signal taken by the side terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the side terminal in the process of measuring the side positioning reference signal, the timing error group factor is related to the timing error group adopted by the side terminal to measure the side positioning reference signal, and the number of measurements is used to reflect the number of resources of the side positioning reference signal measured by the side terminal. The configuration coefficient includes the number of side positioning reference signals that the configured side terminal needs to measure for the transmission of the same side positioning reference signal, or the number of side positioning reference signals that the configured side terminal needs to send for the reception of the same side positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured side terminal needs to report. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0362] In some embodiments, the configuration coefficient is configured by high-level signaling. Considering that a sideline terminal may need to measure N sideline positioning reference signal resources when sending a sideline positioning reference signal resource, the third parameter S needs to be multiplied by N. For example, S = N × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0363] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0364] For method 2:

[0365] In some embodiments, the measured parameters include at least one of the following:

[0366] First parameter;

[0367] The second parameter;

[0368] The third parameter.

[0369] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0370] In some embodiments, the sideline terminal determines a first parameter of an adjacent sideline positioning reference signal based on a position difference between a first time domain position and a second time domain position and a first condition. The first time domain position is the time domain position of a resource of a previous sideline positioning reference signal among adjacent sideline positioning reference signals, where the previous sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The second time domain position is the time domain position of a resource of a subsequent sideline positioning reference signal among adjacent sideline positioning reference signals, where the subsequent sideline positioning reference signal is a sideline positioning reference signal received by the sideline terminal or a sideline positioning reference signal sent by the sideline terminal. The first condition is used to limit the position difference to be greater than the sum of a time span of a resource of a previous sideline positioning reference signal and a first measurement capability. The first measurement capability includes a reception processing time, a transmission processing time, or a maximum value of the reception processing time and the transmission processing time. Among them, the receiving processing time is used to reflect the minimum processing time of the sideline terminal for receiving the resources of the sideline positioning reference signal (corresponding to component 4 in Table 2), and the sending processing time is used to reflect the minimum processing time of the sideline terminal for determining the Rx-Tx time difference based on the resources of the sent sideline positioning reference signal.

[0371] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0372] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,sIndicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T proc Indicates the first measurement capability.

[0373] In some embodiments, the sideline terminal determines the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability. The time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or transmitted by the sideline terminal for the last time. The first measurement capability includes the receiving processing time, or the transmitting processing time, or the maximum value of the receiving processing time and the transmitting processing time. Among them, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the transmitting processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the transmitted sideline positioning reference signal. For example, the sideline terminal can determine whether to use the receiving processing time or the transmitting processing time based on whether the sideline positioning reference signal is actually received first and then transmitted or transmitted first and then received.

[0374] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0375] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0376] Number of samples;

[0377] Receive beam factor;

[0378] Timing error group factor;

[0379] Number of measurements;

[0380] Scaling factor;

[0381] Configuration coefficient + first value.

[0382] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group adopted by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. The configuration coefficient includes the number of sideline positioning reference signals that the configured sideline terminal needs to measure for the transmission of the same sideline positioning reference signal, or the number of sideline positioning reference signals that the configured sideline terminal needs to send for the reception of the same sideline positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured sideline terminal needs to report. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0383] In some embodiments, the configuration coefficient is configured by high-level signaling. In some embodiments, the first value is 1. Multiply S by (N+1), and the coefficient (N+1) is used to represent the total number of sideline positioning reference signal resources sent and received by the sideline terminal. For example, S = (N+1) × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0384] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0385] The steps mentioned in the above embodiments can be implemented as independent embodiments, such as the step of determining the first parameter, the step of determining the second parameter and the step of determining the third parameter, which can be implemented separately as a measurement parameter determination method on the sideline terminal side.

[0386] In summary, the method provided in this embodiment determines measurement parameters based on the measurement capabilities of a sideline terminal, and determines the measurement time of a sideline positioning reference signal based on these measurement parameters. This provides a method for determining the measurement time of a bilateral RTT based on the Rx-Tx time difference based on the measurement capabilities of the sideline terminal. Furthermore, for sideline terminals with different measurement capabilities, the determined measurement time can be tailored to their respective capabilities.

[0387] The method provided in this embodiment also determines the first, second, and third parameters based on the measurement capabilities, thereby determining the parameters used to calculate the measurement time based on the measurement capabilities, making the calculation process more consistent with the terminal's measurement capabilities. Furthermore, the method provided in this embodiment also provides methods for determining the first, second, and third parameters. By determining the scaling factor of the third parameter based on the measurement capabilities of the sideline terminal, a more reasonable measurement time can be determined.

[0388] It should be noted that the order of the method steps provided in the embodiments of the present application can be appropriately adjusted, the steps can also be increased or decreased accordingly according to the circumstances, and different steps can be freely combined to form new embodiments. Any person skilled in the art who is familiar with the present invention can easily think of the method of variation within the technical scope disclosed in this application, and should be included in the protection scope of this application, so it will not be repeated here. In addition, the order of the above-mentioned different situations does not have a preferred meaning, but is only for the convenience of expression.

[0389] FIG16 is a block diagram of a device for determining a measurement time provided by an exemplary embodiment of the present application, wherein the device can be implemented as a sideline terminal or as a part of a sideline terminal through software or hardware or a combination of both.

[0390] Determination module 1601 is configured to determine a measurement parameter based on the measurement capability of a sidelink terminal, wherein the measurement parameter is used to determine a measurement time of a sidelink positioning reference signal, and the measurement capability is used to reflect the ability of the sidelink terminal to measure the sidelink positioning reference signal. The sidelink positioning reference signal includes a reference signal used for positioning transmitted via a sidelink, such as a sidelink positioning reference signal (SL PRS).

[0391] In some embodiments, depending on the measurement quantity (measurement method) of the sideways positioning reference signal, the determination of the measurement time can be divided into the following three determination methods.

[0392] For the first determination method:

[0393] In some embodiments, the sideways positioning reference signal measurement method corresponding to the first determination method includes at least one of the following:

[0394] RSTD measurement;

[0395] RTOA measurements;

[0396] RSRP measurement;

[0397] RSRPP measurement;

[0398] AOA measurement;

[0399] ZOA measurement;

[0400] Rx-Tx time difference measurement.

[0401] The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. For example, after receiving the SL PRS sent by the sideline terminal A, the sideline terminal B needs to send the SL PRS to the sideline terminal A to measure the single-sided RTT value. In some embodiments, the Rx-Tx time difference measurement includes two definitions: (1) the sideline terminal does not need to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference; (2) the sideline terminal needs to wait for the actual transmission of an SL PRS to determine the measurement result of the Rx-Tx time difference. In some embodiments, for the Rx-Tx time difference measurement, when it is not required to use the actual sideline positioning reference signal transmission time to determine the measurement result of the Rx-Tx time difference (Definition 1), that is, when it is not necessary to consider the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals, the first determination method can be used to determine the measurement time.

[0402] In some embodiments, the measured parameters include at least one of the following:

[0403] First parameter;

[0404] The second parameter;

[0405] The third parameter.

[0406] The first parameter is used to reflect the interval between the sth and s+1th measurements (receptions) of the sideline positioning reference signal by the sideline terminal, where s is a positive integer and not greater than S. The second parameter is used to reflect the time when the sideline terminal last measured the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0407] In some embodiments, the determination module 1601 is used to determine the first parameter of the sidelink positioning reference signal measured by the sidelink terminal for the sth time based on the position difference between the first time domain position and the second time domain position and a first condition; wherein the first time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, the second time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the (s+1)th time, the first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability, the time span of the sth measurement is used to reflect the time span of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, and the first measurement capability is used to reflect the minimum processing time of the sidelink terminal for receiving the resource of the sidelink positioning reference signal.

[0408] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0409] In some embodiments, if a sidelink positioning reference signal resource of the next period that belongs to the same sidelink positioning reference signal resource group as the sidelink positioning reference signal appears during the sidelink terminal's processing time for the sidelink positioning reference signal, the sidelink terminal will discard the sidelink positioning reference signal. In some embodiments, for sidelink positioning reference signals within a time domain unit (e.g., a slot), an identity document (ID) can be used to identify whether they belong to the same sidelink positioning reference signal resource. Multiple periodic sidelink positioning reference signal resources sent by the same sidelink terminal can be regarded as a sidelink positioning reference signal resource group / set.

[0410] In some embodiments, when the sideline terminal only needs to measure one sideline positioning reference signal resource group, T slprs,dur The time of a time domain unit (such as slot). If the measurement time is calculated in ms, a time slot of 15kHz corresponds to 1ms, that is, T slprs,dur =1ms.

[0411] In some embodiments, when a sideline terminal needs to measure multiple sideline positioning reference signal resource groups, T slprs,dur is the total time span of the side positioning reference signal resource for each processing. slprs,dur The value of is the total time span of multiple sidelink positioning reference signal resources within each sampling period, each occasion, or each period. For example, it is the time span from the start of the first sidelink positioning reference signal resource's time slot to the end of the last sidelink positioning reference signal resource's time slot, including any unused time slots in between. Similarly, it can be converted to units such as milliseconds based on the number of time slots.

[0412] In some embodiments, the determination module 1601 is used to determine the second parameter based on the sum of the time span of the last measurement and the first measurement capability; wherein, the time span of the last measurement is used to reflect the time span of the resources of the sideline positioning reference signal measured by the sideline terminal for the last time, and the first measurement capability is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal.

[0413] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the sideline positioning reference signal resource measured by the sideline terminal for the last time / last period / Sth time. The determination method can refer to the relevant content above. proc Indicates the first measurement capability (corresponding to component 4 in Table 2).

[0414] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0415] Number of samples;

[0416] Receive beam factor;

[0417] Timing error group factor;

[0418] Number of measurements;

[0419] Scaling factor

[0420] The sampling number reflects the number of sideline positioning reference signal samples taken by the sideline terminal, the receive beam factor reflects the number of receive beams traversed by the sideline terminal while measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the measurement number reflects the number of sideline positioning reference signal resources measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the sampling number.

[0421] For example, the number of samples is N sample , usually N sample =4 or 1, depending on the measurement capability of the sideline terminal. The receiving beam factor is N RxBeam For example, the side positioning reference signal supports FR2, then N RxBeam =8, or the receive beam sweeping factor parameter reported by the sideline terminal. The timing error group factor is k multiTEG , please refer to the above introduction to DL PRS. In some embodiments, N RxBeam and k multiTEG The determination of these two parameters may refer to DL PRS measurement. For example, the side positioning reference signal also supports FR2 or TEG function and may be used in DL PRS.

[0422] In some embodiments, the sideline terminal determines the scaling factor based on the configuration of the sideline positioning reference signal to be measured. For example, if the number of sideline positioning reference signal resources activated at a certain moment exceeds the measurement capability of the sideline terminal, or the number of time domain units (time slots) carrying activated sideline positioning reference signals at a certain moment exceeds the measurement capability of the sideline terminal, the measurement time needs to be further extended.

[0423] In some embodiments, the scaling factor is related to at least one of the second measurement capability and the third measurement capability of the sideline terminal; wherein the second measurement capability is used to reflect the maximum number of resources of the activated sideline positioning reference signal supported and processed by the sideline terminal, and the third measurement capability is used to reflect the maximum number of time domain units carrying the activated sideline positioning reference signal supported and processed by the sideline terminal.

[0424] In some embodiments, the scaling factor includes a first scaling factor; the determining module 1601 is configured to determine the first scaling factor based on a ratio of the first information to the second measurement capability to determine the third parameter; wherein the first information includes the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure. For example, the number of resources of the sideline positioning reference signal that the configured sideline terminal needs to measure is X_cfg, and the second measurement capability is X_ue. Assuming that in the worst case all sideline positioning reference signals are activated simultaneously, the first scaling factor S1 is related to (X_cfg / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1 = ceil(X_cfg / X_ue).

[0425] In some embodiments, the scaling factor includes a first scaling factor; the determining module 1601 is configured to determine the first scaling factor based on a ratio of the second information and the second measurement capability to determine the third parameter; wherein the second information includes the number of resources of the sideline positioning reference signals actually activated simultaneously or the maximum number of resources of the sideline positioning reference signals actually activated simultaneously. For example, the number of resources of the sideline positioning reference signals actually activated simultaneously is X_act, the maximum value of the number of resources of the sideline positioning reference signals actually activated simultaneously is X_act=max(X_act,i), the second measurement capability is X_ue, and the first scaling factor S1 is related to (X_act / X_ue), for example, rounding up or rounding down (X_cfg / X_ue), for example, S1=ceil(X_act / X_ue).

For example, the third information is X_3=min(X_cfg, (Npro+second value)*K), K is the maximum number of resources of the sideline positioning reference signal configured on each time domain unit (time slot). Npro is the T of the sideline terminal. proc(ms) corresponds to the number of time slots. It is assumed here that the period of the side positioning reference signal is greater than the processing time of the side terminal, otherwise the resources of multiple periods of the same side positioning reference signal may be reproduced within the Npro processing delay. In some embodiments, the second value is 1, and the time slot in which the side positioning reference signal itself is located is considered. The first scaling factor is related to (X_3 / X_ue), for example, rounding up or rounding down (X_3 / X_ue), for example, S1=ceil(X_3 / X_ue).

[0427] In some embodiments, the scaling factor includes a second scaling factor; the determining module 1601 is configured to determine the second scaling factor based on a ratio of the seventh information to the third measurement capability to determine the third parameter; wherein the seventh information is used to reflect the number of time domain units configured to carry the sidelink positioning reference signal, the seventh information is equal to the first information, and the first information includes the number of resources of the sidelink positioning reference signal configured to be measured by the sidelink terminal. For example, according to the configuration, the number of time slots carrying the sidelink positioning reference signal can be determined as Y_cfg = X_cfg, and the third measurement capability is Y_ue, where Y_cfg assumes that, in a worst-case scenario, all sidelink positioning reference signal resources are dispersed across different time slots and activated simultaneously. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, by rounding up or down (Y_cfg / Y_ue), for example, S2 = ceil(Y_cfg / Y_ue).

[0428] In some embodiments, the scaling factor includes a second scaling factor; the determining module 1601 is configured to determine the second scaling factor based on a ratio of the eighth information to the third measurement capability to determine the third parameter; wherein the eighth information includes the number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously or the maximum number of time domain units corresponding to the sideline positioning reference signals that are actually activated simultaneously. For example, the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act, and the maximum value of the number of time slots corresponding to the sideline positioning reference signals that are actually activated simultaneously is Y_act=max(Y_act,i), and the second scaling factor S2 is related to (Y_act / Y_ue), for example, rounding up or rounding down (Y_act / Y_ue), for example, S2=ceil(Y_act / Y_ue).

[0429] In some embodiments, the scaling factor includes a second scaling factor; the determination module 1601 is configured to determine the second scaling factor based on the ratio of the ninth information to the third measurement capability to determine the third parameter; wherein the ninth information includes the minimum value of the first information and the information determined based on the fifth information, the first information includes the number of resources of the side positioning reference signal that the configured side terminal needs to measure, the fifth information includes the number of time domain units corresponding to the first measurement capability, and the first measurement capability is used to reflect the minimum processing time for the side terminal to receive the resources of the side positioning reference signal. For example, the number of time slots containing the side positioning reference signal (ninth information) determined according to the configuration is Y_cfg=min(X_cfg,Npro+1), and the third measurement capability is Y_ue. Wherein Y_cfg is the assumption that in the worst case, all the resources of the side positioning reference signal are scattered in different time slots and activated at the same time. Npro is the T of the side terminal. proc In some embodiments, the third value is 1. The second scaling factor S2 is related to (Y_cfg / Y_ue), for example, rounding up or down (Y_cfg / Y_ue), for example, S2 = ceil (Y_cfg / Y_ue).

[0430] In some embodiments, when the third measurement capability of the sideline terminal is not defined, or the third measurement capability is set to be large by default, it may be considered that S2=1.

[0431] In some embodiments, the first scaling factor and the second scaling factor may be multiplied by the number of samples and / or other scaling factors used to determine the third parameter to obtain the third parameter. For example, S = S1 × S2 × N sample ×k multiTEG ×N RxBeam , or S=ceil(S1×S2×N sample ×k multiTEG ×N RxBeam ), when calculating S1 or S2, you can calculate the final S without rounding up first, and multiply all scaling factors and then round up.

[0432] In some embodiments, if the periodicity of the sidelink positioning reference signal resources measured by the sidelink terminal is different, the above parameters may be determined based on the sidelink positioning reference signal resources with the maximum period.

[0433] In some embodiments, the third parameter is related to the number of sideline positioning reference signal resources measured by the sideline terminal, for example, S=measured number of SL PRS resources×N sample , at this time T effect Indicates the time interval between two adjacent sideline positioning reference signal resources.

[0434] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0435] Regarding the second determination method:

[0436] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes Rx-Tx time difference measurement. Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, Rx-Tx time difference measurement includes two definitions. In some embodiments, for Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the second determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the second determination method includes single-sided RTT measurement based on Rx-Tx time difference.

[0437] In some embodiments, the second determination method can be further divided into the following two determination methods.

[0438] For method 1:

[0439] In some embodiments, the measured parameters include at least one of the following:

[0440] First parameter;

[0441] The second parameter;

[0442] The third parameter.

[0443] The first parameter is used to reflect the interval between the sth and s+1th measurements of the sideline positioning reference signal by the sideline terminal, where s is a positive integer. The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0444] In some embodiments, the determination module 1601 is used to determine the first parameter of the sidelink positioning reference signal measured by the sidelink terminal for the sth time based on the position difference between the first time domain position and the second time domain position and a first condition; wherein the first time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, the second time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the (s+1)th time, the first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability, the time span of the sth measurement is used to reflect the time span of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, the first measurement capability includes the receiving processing time or the maximum value of the receiving processing time and the sending processing time, the receiving processing time is used to reflect the minimum processing time for the sidelink terminal to receive the resource of the sidelink positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sidelink terminal to determine the Rx-Tx time difference based on the resource of the sent sidelink positioning reference signal.

[0445] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0446] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, T proc Indicates the first measurement capability.

[0447] In some embodiments, method 1 is applicable to the situation where each sidelink positioning reference signal reception of the sidelink terminal corresponds to a sidelink positioning reference signal transmission, and / or the time when the sidelink terminal transmits the sidelink positioning reference signal is no later than the sidelink positioning reference signal reception of the next period.

[0448] In some embodiments, the determining module 1601 is configured to determine the second parameter according to the sum of the time span of the last measurement and the first measurement capability; wherein, the time span of the last measurement is used to reflect the time span of the resource of the sidelink positioning reference signal measured and transmitted by the sidelink terminal last time, the first measurement capability includes the reception processing time or the maximum value of the reception processing time and the transmission processing time, the reception processing time is used to reflect the minimum processing time for the sidelink terminal to receive the resource of the sidelink positioning reference signal, and the transmission processing time is used to reflect the minimum processing time for the sidelink terminal to determine the Rx-Tx time difference according to the resource of the transmitted sidelink positioning reference signal.

[0449] Exemplarily, the above process can be expressed as: T last = T slprs,dur,S + T proc . Wherein, T last represents the second parameter, and T slprs,dur,S represents the time span (duration) of the resource of the sidelink positioning reference signal received and transmitted by the sidelink terminal in the last measurement / the last cycle / the Sth measurement. T proc represents the first measurement capability. For example, sidelink terminal B receives the SL PRS of the last time slot in slot#n and transmits the SL PRS of the last time slot in slot#m, then T slprs,dur,S is from the start time of slot#n to the end time of slot#m, a total of (m - n + 1) time slots. In some embodiments, if the SL PRS for measuring the Rx-Tx time difference is transmitted before the SL PRS is received, that is, m < n, then T slprs,dur,S only needs to consider the duration of the received SL PRS. In this case, T slprs,dur,S is (n - m + 1) time slots. Reference can be made to the relevant content in the first determination method.

[0450] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0451] · The number of samples;

[0452] · The receive beam factor;

[0453] · The timing error group factor;

[0456] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG It should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0457] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0458] For method 2:

[0459] In some embodiments, the measured parameters include at least one of the following:

[0460] First parameter;

[0461] The second parameter;

[0462] The third parameter.

[0463] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0464] In some embodiments, the determination module 1601 is used to determine the first parameter of the adjacent side positioning reference signal based on the position difference between the first time domain position and the second time domain position and a first condition; wherein the first time domain position is the time domain position of the resource of the previous side positioning reference signal in the adjacent side positioning reference signal, and the second time domain position is the time domain position of the resource of the next side positioning reference signal in the adjacent side positioning reference signal. The first condition is used to limit the position difference to be greater than the sum of the time span of the resource of the previous side positioning reference signal and the first measurement capability. The first measurement capability includes the receiving processing time or the sending processing time or the maximum value of the receiving processing time and the sending processing time. The receiving processing time is used to reflect the minimum processing time for the side terminal to receive the resource of the side positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the side terminal to determine the Rx-Tx time difference based on the resource of the sent side positioning reference signal.

[0465] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0466] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T proc Indicates the first measurement capability.

[0467] In some embodiments, the determination module 1601 is used to determine the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability; wherein, the time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or sent by the sideline terminal for the last time, and the first measurement capability includes the receiving processing time or the sending processing time or the maximum value of the receiving processing time and the sending processing time, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the sideline positioning reference signal sent.

[0468] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0471] Receive beam factor;

[0472] Timing error group factor;

[0473] Number of measurements;

[0474] Scaling factor;

[0475] Specify the coefficient.

[0476] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group used by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG It should be noted that, for the method of determining the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the present application will not be elaborated here.

[0477] In some embodiments, the specified coefficient is 2. For example, the third parameter is calculated as S=2×S1×S2×N sample ×k multiTEG ×N RxBeam , which can be regarded as a specified coefficient to amplify S by 2 times, that is, to amplify the number of measurements by 2 times, to reflect that the transmission and reception corresponding to the measurement of the sideline terminal will each correspond to a sideline positioning reference signal resource.

[0478] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0479] Regarding the third determination method:

[0480] In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes Rx-Tx time difference measurement. The Rx-Tx time difference measurement is achieved by the sideline terminal by receiving and sending the sideline positioning reference signal. In some embodiments, as described above, the Rx-Tx time difference measurement includes two definitions. In some embodiments, for the Rx-Tx time difference measurement, when the measurement result of the Rx-Tx time difference must be determined after the sideline positioning reference signal actually sent by the sideline terminal to other sideline terminals is finished (Definition 2), the third determination method can be used to determine the measurement time. In some embodiments, the measurement method of the sideline positioning reference signal corresponding to the third determination method includes a double-sided RTT measurement based on the Rx-Tx time difference. Bilateral RTT measurement can reduce the impact of frequency offset. High-layer signaling can configure / instruct the sidelink terminal to measure N Rx-Tx time differences for one sidelink positioning reference signal resource, such as one sidelink positioning reference signal reception + N sidelink positioning reference signal transmissions, or one sidelink positioning reference signal transmission + N sidelink positioning reference signal receptions.

The second parameter is used to reflect the time when the sideline terminal last measured and sent the sideline positioning reference signal. The third parameter is used to reflect the number of times the sideline terminal measured the sideline positioning reference signal. For example, the first parameter is T effect , the second parameter is T last , the third parameter is S.

[0488] In some embodiments, the determination module 1601 is used to determine the first parameter of the sidelink positioning reference signal measured by the sidelink terminal for the sth time based on the position difference between the first time domain position and the second time domain position and a first condition; wherein the first time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, the second time domain position is the time domain position of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the (s+1)th time, the first condition is used to limit the position difference to be greater than the sum of the time span of the sth measurement and the first measurement capability, the time span of the sth measurement is used to reflect the time span of the resource of the sidelink positioning reference signal measured by the sidelink terminal for the sth time, the first measurement capability includes the receiving processing time or the maximum value of the receiving processing time and the sending processing time, the receiving processing time is used to reflect the minimum processing time for the sidelink terminal to receive the resource of the sidelink positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sidelink terminal to determine the Rx-Tx time difference based on the resource of the sent sidelink positioning reference signal.

[0489] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0490] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter of the sideline positioning reference signal measured by the sideline terminal for the sth time, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the sideline positioning reference signal resource measured by the sideline terminal for the sth time, Tproc Indicates the first measurement capability.

[0491] In some embodiments, mode 1 is applicable to the situation where every N sidelink positioning reference signals received by the sidelink terminal corresponds to one sidelink positioning reference signal sent.

[0492] In some embodiments, the determination module 1601 is used to determine the second parameter based on the sum of the time span of the last measurement and the first measurement capability; wherein, the time span of the last measurement is used to reflect the time span of the resources of the sideline positioning reference signal last measured and sent by the sideline terminal, and the first measurement capability includes the receiving processing time or the maximum value of the receiving processing time and the sending processing time, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the sideline positioning reference signal sent.

[0493] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving and sending the sideline positioning reference signal of the sideline terminal in the last measurement / last cycle / Sth measurement, depending on whether the sideline terminal sends the sideline positioning reference signal first and then receives it, or receives it first and then sends it. proc Indicates the first measurement capability.

The configuration coefficient includes the number of side positioning reference signals that the configured side terminal needs to measure for the transmission of the same side positioning reference signal, or the number of side positioning reference signals that the configured side terminal needs to send for the reception of the same side positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured side terminal needs to report. In some embodiments, the value of the third parameter is at least related to the number of samples. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0502] In some embodiments, the configuration coefficient is configured by high-level signaling. Considering that a sideline terminal may need to measure N sideline positioning reference signal resources when sending a sideline positioning reference signal resource, the third parameter S needs to be multiplied by N. For example, S = N × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0503] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth measurement, T last Indicates the second parameter.

[0504] For method 2:

[0508] The third parameter.

[0509] The first parameter is used to reflect the interval between the resources of adjacent sideline positioning reference signals of the sideline terminal. The second parameter is used to reflect the time when the sideline terminal last measured or sent the sideline positioning reference signal. The third parameter is used to reflect the number of resources of the sideline positioning reference signal of the sideline terminal. For example, the positioning reference signal of the sideline terminal includes the sideline positioning reference signal received and the sideline positioning reference signal sent by the sideline terminal during the measurement process. Adjacent sideline positioning reference signals can be divided into the following cases: sending sideline positioning reference signal-receiving sideline positioning reference signal, receiving sideline positioning reference signal-sending sideline positioning reference signal, sending sideline positioning reference signal-sending sideline positioning reference signal, and receiving sideline positioning reference signal-receiving sideline positioning reference signal.

[0510] In some embodiments, the determination module 1601 is used to determine the first parameter of the adjacent side positioning reference signal based on the position difference between the first time domain position and the second time domain position and a first condition; wherein the first time domain position is the time domain position of the resource of the previous side positioning reference signal in the adjacent side positioning reference signal, and the second time domain position is the time domain position of the resource of the next side positioning reference signal in the adjacent side positioning reference signal. The first condition is used to limit the position difference to be greater than the sum of the time span of the resource of the previous side positioning reference signal and the first measurement capability. The first measurement capability includes the receiving processing time or the sending processing time or the maximum value of the receiving processing time and the sending processing time. The receiving processing time is used to reflect the minimum processing time for the side terminal to receive the resource of the side positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the side terminal to determine the Rx-Tx time difference based on the resource of the sent side positioning reference signal.

[0511] In some embodiments, the transmit processing time is different from the receive processing time. In some embodiments, the transmit processing time is the same as the receive processing time. In some embodiments, the transmit processing time is a shared capability with the receive processing time.

[0512] For example, the above process can be expressed as: T effect,s =t s+1 -t s , and satisfies T effect,s >T slprs,dur,s +T proc Among them, T effect,s Indicates the first parameter corresponding to the sth and s+1th sideline positioning reference signals of the sideline terminal, t s+1 represents the second time domain position, t s represents the first time domain position, T slprs,dur,s Indicates the time span of the resource of the sth sideline positioning reference signal of the sideline terminal, T procIndicates the first measurement capability.

[0513] In some embodiments, the determination module 1601 is used to determine the second parameter based on the sum of the time span of the last measurement or transmission and the first measurement capability; wherein, the time span of the last measurement or transmission is used to reflect the time span of the resources of the sideline positioning reference signal measured or sent by the sideline terminal for the last time, and the first measurement capability includes the receiving processing time or the sending processing time or the maximum value of the receiving processing time and the sending processing time, the receiving processing time is used to reflect the minimum processing time for the sideline terminal to receive the resources of the sideline positioning reference signal, and the sending processing time is used to reflect the minimum processing time for the sideline terminal to determine the Rx-Tx time difference based on the resources of the sideline positioning reference signal sent.

[0514] For example, the above process can be expressed as: T last =T slprs,dur,S +T proc Among them, T last Represents the second parameter, T slprs,dur,S Indicates the time span (duration) of the resources for receiving or sending the sideline positioning reference signal in the last measurement / last period / Sth measurement of the sideline terminal. proc Indicates the first measurement capability.

[0515] In some embodiments, the third parameter is positively correlated with at least one of the following parameters:

[0516] Number of samples;

[0517] Receive beam factor;

[0518] Timing error group factor;

[0519] Number of measurements;

[0520] Scaling factor;

[0521] Configuration coefficient + first value.

[0522] Among them, the number of samples is used to reflect the number of samples of the sideline positioning reference signal taken by the sideline terminal, the receiving beam factor is used to reflect the number of receiving beams traversed by the sideline terminal in the process of measuring the sideline positioning reference signal, the timing error group factor is related to the timing error group adopted by the sideline terminal to measure the sideline positioning reference signal, and the number of measurements is used to reflect the number of resources of the sideline positioning reference signal measured by the sideline terminal. The configuration coefficient includes the number of sideline positioning reference signals that the configured sideline terminal needs to measure for the transmission of the same sideline positioning reference signal, or the number of sideline positioning reference signals that the configured sideline terminal needs to send for the reception of the same sideline positioning reference signal, or the number of measurement results of the reception and transmission time difference that the configured sideline terminal needs to report. For example, the number of samples is N sample , the receiving beam factor is N RxBeam , the timing error group factor is k multiTEG , the configuration coefficient is N. It should be noted that, for the determination method of the scaling factor, reference may be made to the relevant content in the first determination method mentioned above, and this embodiment of the application will not be elaborated here.

[0523] In some embodiments, the configuration coefficient is configured by high-level signaling. In some embodiments, the first value is 1. Multiply S by (N+1), and the coefficient (N+1) is used to represent the total number of sideline positioning reference signal resources sent and received by the sideline terminal. For example, S = (N+1) × S1 × S2 × N sample ×k multiTEG ×N RxBeam .

[0524] In some embodiments, after determining the first parameter, the second parameter, and the third parameter, the sideline terminal can use the formula Determine the measurement time. Where, T SL RSTD Indicates the calculated measurement time, S represents the third parameter, T effect,s represents the first parameter corresponding to the sth adjacent side positioning reference signal, T last Indicates the second parameter.

[0525] In summary, the apparatus provided in this embodiment determines measurement parameters based on the measurement capabilities of a sideline terminal, and determines the measurement time of a sideline positioning reference signal based on the measurement parameters. This provides a method for determining the measurement time of a sideline positioning reference signal based on the measurement capabilities of a sideline terminal.
