[0047] To better understand the technical solution of this application, the following content will be introduced first:

[0048] V2X Introduction

[0049] like Figure 1aAs shown, the LTE system supports SL transmission, meaning data transmission between UEs directly at the physical layer. LTE sidelink is broadcast-based, which, while suitable for supporting basic security-class V2X communication, is not applicable to more advanced V2X services. The 5G NR system will support more advanced sidelink transmission designs, such as unicast, multicast, or multicast, thus supporting a wider range of service types.

[0050] Resource allocation

[0051] NR V2X defines two resource allocation modes: mode 1, where resources are allocated by the base station; and mode 2, where the UE decides which resources to use for transmission. Resource information may come from base station broadcast messages or pre-configured information. If the UE is within range of the base station and has an RRC connection with it, it can operate in mode 1 and / or mode 2. If the UE is within range of the base station but does not have an RRC connection, it can only operate in mode 2. If the UE is outside range of the base station, it can only operate in mode 2 and perform V2X transmissions according to the pre-configured information.

[0052] For mode 2, the specific operation is as follows: 1) After resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after the resource selection is triggered, and the upper boundary is at time T2 after the trigger. T2 is the value selected by the UE within the PDB (packet delay budget) of its Transport Block (TB) transmission, and T2 is no earlier than T1. 2) Before resource selection, the UE needs to determine the candidate resource set. The Reference Signal Received Power (RSRP) measured on the resources within the resource selection window is compared with the corresponding RSRP threshold. If the RSRP is lower than the RSRP threshold, then the resource can be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. Additionally, the UE can reserve transmission resources for subsequent transmissions during this transmission. The specific process is as follows: Figure 1b As shown.

[0053] The following problems currently exist in NR communication:

[0054] Question 1: Sidelink positioning is not currently supported.

[0055] Question 2: If sidelink positioning is supported, is it possible to use the configured active BWP for positioning, or to use a dedicated BWP for positioning?

[0056] Question 3: If a dedicated BWP is used for sidelink positioning, will it affect other transmissions or measurements on the active BWP? Or, given the bandwidth limitations of the existing sidelink BWP, will the positioning accuracy be affected?

[0057] The processing method for positioning reference signals provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0058] See Figure 2 This application provides a method for processing a positioning reference signal, wherein the method is executed by a terminal, and the method includes:

[0059] Step 201: The terminal transmits or measures the SL positioning reference signal on the target resource outside the SL BWP or the target resource outside the SL resource pool, according to the terminal capability and / or SL positioning reference signal configuration information; or, the terminal transmits or measures the SL positioning reference signal within the SL BWP or the SL resource pool, according to the terminal capability and / or SL positioning reference signal configuration information.

[0060] The aforementioned SL positioning reference signal is the SL signal used for positioning.

[0061] It should be noted that the above transmission operations specifically refer to sending or receiving between two terminals, such as terminal 1 sending an SL-PRS to terminal 2, or terminal 1 receiving an SL-PRS from terminal 2. In the following scheme descriptions, the transmissions mentioned are general descriptions of sending and receiving. It is understood that the following scheme descriptions apply to two terminals performing SL communication, such as: 1) data transmission between the sending terminal and the receiving terminal; 2) information exchange between the scheduling terminal and the sending terminal; and 3) information exchange between the scheduling terminal and the receiving terminal.

[0062] It should be noted that the SL positioning reference signal configuration information mentioned above can be configured by the network device to the terminal, or it can be sent to the terminal by other terminals. This application embodiment does not specifically limit the source of the SL positioning reference signal configuration information.

[0063] Optionally, the SL positioning reference signal can be an SL signal used for positioning;

[0064] Optionally, the SL positioning reference signal can be a multiplexed NR positioning signal, an existing SL signal or an enhancement thereof, such as a Channel State Information Reference Signal (CSI-RS), a sidelink synchronization signal block (S-SSB), a tracking reference signal (TRS), or a demodulation reference signal (DMRS).

[0065] Optionally, the SL positioning reference signal can be a NR SL positioning signal specifically defined for positioning, and the signal includes, but is not limited to, gold code sequences, m sequences, and ZC sequences.

[0066] Optionally, the SL positioning reference signal can be either SL-PRS or SL SRS;

[0067] It is worth noting that SL-PRS mentioned below is only used to refer to the SL positioning reference signal, and does not limit the SL positioning reference signal to the above-mentioned SL-PRS.

[0068] Optionally, the SL positioning reference signal can be a variety of signals.

[0069] It should be noted that SL BWP specifically refers to the active BWP that is currently configured in NR communication, and SL resource pool refers to the resource pool that is configured in the active BWP. Correspondingly, target resources outside of SL BWP are used to refer to dedicated BWPs outside of active BWP, and target resources outside of SL resource pool are used to refer to dedicated resource pools outside of the configured resource pools.

[0070] In some implementations, the aforementioned dedicated BWP can be an unlicensed band.

[0071] In some implementations, the aforementioned dedicated BWP can be a defined sidelink frequency layer.

[0072] In this embodiment, the terminal transmits or measures the SL positioning reference signal outside the SL BWP or SL resource pool, or transmits or measures the SL positioning reference signal within the SL BWP or SL resource pool, based on terminal capabilities and / or SL positioning reference signal configuration information, thereby clarifying the BWP or resource pool used for SL positioning and realizing SL positioning in NR communication.

[0073] In one possible implementation, transmitting or measuring an SL positioning reference signal on a target resource outside the SL BWP or SL resource pool includes any of the following:

[0074] (1) Transmit or measure SL positioning reference signals on the target SL BWP (e.g., dedicated BWP) or the target SL resource pool (e.g., dedicated resource pool);

[0075] (2) Transmit or measure the SL positioning reference signal on the SL frequency layer;

[0076] (3) Transmit or measure the SL positioning reference signal on the first resource subset, i.e., SL-PRS is transmitted or measured in an independent subset, which can be a time slot, symbol, or time-frequency resource.

[0077] In the above embodiments, it can be understood that the terminal is configured with at least two BWPs, wherein the target SL BWP can be used to transmit the SL positioning reference signal. The original SL BWP is used to transmit a first signal or a first channel other than the SL positioning reference signal; or, the terminal is configured with an SL frequency layer, wherein the SL positioning reference signal is configured on the SL frequency layer.

[0078] Optionally, the terminal is configured with a separate first resource subset on which the SL positioning reference signal is transmitted or measured; that is, the SL-PRS is transmitted or measured in an independent subset, which can be a time slot, symbol, or time-frequency resource. Optionally, if a first resource subset for transmitting or measuring the SL positioning reference signal is configured, this first resource subset must be excluded when defining the SL resource pool.

[0079] In one possible implementation, when transmitting or measuring the SL positioning reference signal within the SL BWP or SL resource pool, the SL positioning reference signal satisfies one or more of the following:

[0080] (1) The first parameter of the SL positioning reference signal is the same as the first parameter of the SL BWP, which includes the subcarrier spacing (SCS) and / or cyclic prefix (CP) type;

[0081] For example, configure the SCS and CP types within the SL BWP or SL resource pool, or directly indicate that the SCS and CP types are the same as the SL BWP or SL resource pool.

[0082] (2) The period of the SL positioning reference signal is an integer multiple of the period of the SL resource pool;

[0083] The period can be a physical period or a logical period;

[0084] The logical period is the period calculated based on the resources used for SL, such as excluding DL resources and resources used for S-SSB, and the period calculated using the resources that can be used to transmit SL.

[0085] It should be noted that the physical cycle may not be configured at equal time intervals. Therefore, the corresponding resources configured at equal time intervals may not be available resources for SL. In such cases, the transmission needs to be postponed to the first or a certain available SL resource.

[0086] For logical cycles, the cycle can be calculated based on the resources used for SL, such as excluding DL resources and resources used for S-SSB, and the cycle can be calculated using the resources that can be used to transmit SL.

[0087] (3) The time slot for transmitting the SL positioning reference signal is the available slot for SL transmission;

[0088] (4) The transmission symbol of the SL positioning reference signal is the Nth symbol in the SL resource pool, where N is a positive integer;

[0089] (5) The bandwidth of the SL positioning reference signal is less than or equal to the bandwidth of the SL BWP or SL resource pool.

[0090] In one possible implementation, when transmitting or measuring the SL positioning reference signal within the SL BWP or SL resource pool, the method further includes one or more of the following:

[0091] (1) If the first parameter of the SL positioning reference signal is different from the first parameter of the SL BWP, the terminal stops transmitting or measuring the SL positioning reference signal, that is, the terminal does not expect to process the SL-PRS.

[0092] (2) When the SL positioning reference signal transmission slot is a slot outside the SL resource pool, the terminal stops transmitting or measuring the SL positioning reference signal on the transmission slot, that is, the terminal does not expect to process the SL-PRS in that period or slot.

[0093] (3) When the bandwidth of the SL positioning reference signal is greater than the bandwidth of the SL BWP or the SL resource pool, the terminal stops transmitting or measuring the SL positioning reference signal outside the SL BWP or the SL resource pool, that is, the terminal does not expect to process the SL-PRS outside the SL BWP or the SL resource pool.

[0094] (4) If the bandwidth of the SL positioning reference signal is greater than the bandwidth of the SL BWP or the SL resource pool, the terminal stops transmitting or measuring the SL positioning reference signal, that is, the terminal does not expect to process the SL-PRS.

[0095] In one possible implementation, when transmitting or measuring the SL positioning reference signal on a target resource outside the SL BWP or SL resource pool, the SL positioning reference signal satisfies one or more of the following:

[0096] (1) The first parameter of the SL positioning reference signal is different from the first parameter of the SL BWP. The first parameter includes SCS and / or CP type;

[0097] (2) The period of the SL positioning reference signal is a non-integer multiple of the period of the SL resource pool;

[0098] (3) The SL positioning reference signal transmission slot is a slot outside the SL resource pool;

[0099] (4) The bandwidth of the SL positioning reference signal is greater than the bandwidth of the SL BWP or SL resource pool.

[0100] In one possible implementation, the method further includes: the terminal determining, based on its capabilities, to configure the SL positioning reference signal on the SL BWP or the SL resource pool; or, based on its capabilities, the terminal determining to configure the SL positioning reference signal on a target BWP other than the SLBWP, or to configure the SL positioning reference signal on a target SL resource pool other than the SL resource pool.

[0101] For example, if the UE only supports transmitting information on the SL BWP, then the SL positioning reference signal is configured on the target BWP on the SL BWP; or, if the terminal supports the target BWP, then the SL positioning reference signal can be configured on the target BWP.

[0102] In this embodiment of the application, the terminal determines the corresponding SL positioning reference signal configuration based on its own terminal capabilities;

[0103] Specifically, it can be divided into two methods: Method 1: The UE configures the SL-PRS on the SL-BWP (e.g., activeBWP) or the SL resource pool according to UE capability 1; Method 2: The UE configures the SL-PRS on a dedicated BWP or a dedicated resource pool according to UE capability 2.

[0104] The embodiment may indicate that the UE may optionally have two additional capabilities: capability 0, whether it supports the transmission of SL-PRS; and capabilities 1 and 2, which indicate whether the UE transmits SL-PRS on the SL-BWP or the SL resource pool, or on the target BWP or the target resource pool.

[0105] In one possible implementation, the method further includes:

[0106] (1) The terminal determines or receives information about a target BWP other than the SL BWP, or information about a target SL resource pool other than the SL resource pool;

[0107] Specifically, it can be received from network devices or from other terminals.

[0108] Alternatively, (2) the terminal sends a first message to the network device, the first message being used to request that the SL positioning reference signal be configured on a target BWP other than the SL BWP, or that the SL positioning reference signal be configured on a target SL resource pool other than the SL resource pool; the terminal switches the SL BWP to the target BWP or switches the SL resource pool to the target SL resource pool.

[0109] That is, the terminal configures SL-PRS on SL-BWP or SL resource pool by requesting the network device, or configures SL-PRS on dedicated BWP or dedicated resource pool.

[0110] In one possible implementation, the information of the target BWP includes one or more of the following:

[0111] (1) First frequency domain information, including one or more of the following: reference point (Point A) information, absolute radio frequency channel number (ARFCN) and start physical resource block (start PRB);

[0112] (2) Second frequency domain information, including one or more of the following: number of subchannels, number of consecutive PRBs contained in a subchannel, number of PRBs, PRB bitmap, number of RBs, and starting PRB of the smallest numbered subchannel.

[0113] (3) Third frequency domain information, including frequency layer identifier (ID);

[0114] (4) First time-domain information, including one or more of the start symbol and symbol length.

[0115] In one possible implementation, the information of the target SL resource pool includes one or more of the following:

[0116] (1) Starting symbol or starting slot;

[0117] (2) Symbol length or slot length;

[0118] (3) Termination symbol or termination slot;

[0119] (4) Window information;

[0120] (5) Target resource information;

[0121] (6) Temporal bitmap information;

[0122] (7) Third frequency domain information, including one or more of the following: number of subchannels, number of consecutive PRBs contained in a subchannel, number of PRBs, PRB bitmap, number of RBs, and starting PRB of the smallest numbered subchannel;

[0123] (8) Synchronization information;

[0124] (9) SL positioning reference signal configuration information.

[0125] In one possible implementation, the target BWP satisfies at least one of the following:

[0126] (1) The first parameter of the target BWP is different from the first parameter of the SL BWP. The first parameter includes SCS and / or CP type;

[0127] (2) The starting frequency domain position of the SL positioning reference signal on the target BWP is different from the starting frequency domain position of the SL positioning reference signal on the SL BWP;

[0128] (3) The bandwidth of the SL positioning reference signal on the target BWP is different from the bandwidth of the SL positioning reference signal on the SL BWP;

[0129] (4) The starting symbol of the SL positioning reference signal on the target BWP is different from the starting symbol of the SL positioning reference signal on the SL BWP.

[0130] In one possible implementation, the target SL resource pool satisfies at least one of the following:

[0131] (1) The first parameter of the target SL resource pool is different from the first parameter of the SL resource pool. The first parameter includes SCS and / or CP type;

[0132] (2) The number of subchannels in the target SL resource pool is different from the number of subchannels in the SL resource pool;

[0133] (3) The number of PRBs in the subchannel of the target SL resource pool is different from the number of PRBs in the subchannel of the SL resource pool.

[0134] (4) The temporal bitmap information of the target SL resource pool is different from the SL temporal resources of the SL resource pool;

[0135] (5) The temporal bitmap information of the target SL resource pool is a subset of the SL temporal resources of the SL resource pool;

[0136] (6) The starting symbols of the target SL resource pool are different;

[0137] (7) The starting slot of the target SL resource pool is different from the starting slot of the SL resource pool;

[0138] (8) The starting symbol length of the target SL resource pool is different from the starting symbol length of the SL resource pool;

[0139] (9) The starting slot length of the target SL resource pool is different from the starting slot length of the SL resource pool;

[0140] (10) The period of the target SL resource pool is different from that of the SL resource pool.

[0141] In one possible implementation, when transmitting or measuring the SL positioning reference signal on a target resource outside the SL BWP or SL resource pool, the method further includes:

[0142] (1) When the first signal and / or the first channel are transmitted in the SL BWP or SL resource pool, the terminal stops transmitting or measuring the SL positioning reference signal; thus, when the terminal does not support simultaneous transmission on the active BWP and the dedicated BWP, the terminal prioritizes the transmission on the active BWP and stops the transmission or measurement of the SL-PRS.

[0143] (2) In the presence of a first signal and / or a first channel being transmitted on the target resource, the terminal stops transmitting or measuring the SL positioning reference signal.

[0144] The existence of the first signal and / or the first channel transmission can be understood as other channels or signals potentially causing resource conflicts with SL-PRS.

[0145] The first channel includes one or more of the following:

[0146] Physical Sidelink Broadcast Channel (PSBCH);

[0147] Physical Side Link Shared Channel (PSSCH);

[0148] Physical Sidelink Control Channel (PSCCH);

[0149] Physical Side Link Control Channel (PSFCH);

[0150] The first signal includes one or more of the following:

[0151] Side Link Control Information (SCI);

[0152] Side link synchronization signal block S-SSB;

[0153] Side link master synchronization signal S-PSS;

[0154] Side link auxiliary synchronization signal S-SSS;

[0155] Channel State Information Reference Signal (CSI-RS);

[0156] Demodulation reference signal DMRS;

[0157] Tracking reference signal TRS;

[0158] The first channel includes the first UL channel, comprising one or more of the following:

[0159] Physical Random Access Channel (PRACH);

[0160] Physical uplink control channel (PUCCH);

[0161] Physical Uplink Shared Channel (PUSCH);

[0162] High reliability and low latency communication URLLC channel;

[0163] The first signal includes the first UL signal, which includes:

[0164] Detection reference signal SRS.

[0165] In this embodiment of the application, when processing SL-PRS in a dedicated BWP or dedicated resource pool, if other channels or signals are being processed in the SLBWP or SL resource pool, or in the dedicated BWP or dedicated resource pool, the terminal selects to stop processing SL-PRS.

[0166] It is worth noting that the option to stop processing SL-PRS is also related to priority. For example, if SL-PRS has a higher priority than other channels or signals, it is optional to stop processing other channels or signals.

[0167] In one possible implementation, when transmitting or measuring the SL positioning reference signal on a target resource outside the SL BWP or SL resource pool, the method further includes:

[0168] Transmit the first signal and / or the first channel on the SL BWP or the SL resource pool.

[0169] In the embodiments of this application, when SL-PRS is processed in a dedicated BWP or dedicated resource pool, if there are other channels or signals that need to be processed, the terminal selects the processing method of processing the other channels or signals in the SL BWP or SL resource pool.

[0170] Optionally, this embodiment includes the following two cases: Case 1: Although the SL positioning reference signal is different from the BWP of the first signal and / or the first channel, if the first signal and / or the first channel are transmitted on the SL BWP or the SL resource pool, then the transmission or measurement of the SL positioning reference signal is stopped, and only the transmission of the first signal and / or the first channel on the SL BWP or the SL resource pool is processed.

[0171] Scenario 2: If the SL positioning reference signal is different from the BWP of the first signal and / or the first channel, then the first signal and / or the first channel are transmitted on the SL BWP or the SL resource pool, and the SL positioning reference signal is transmitted or measured on the target BWP or the target SL resource pool.

[0172] In one possible implementation, when transmitting or measuring the SL positioning reference signal within the SL BWP or SL resource pool, the method further includes:

[0173] If a first signal and / or a first channel are being transmitted within the SL BWP or SL resource pool, the terminal stops transmitting or measuring the SL positioning reference signal.

[0174] In this embodiment of the application, when processing SL-PRS in the SL BWP or SL resource pool, if there are other channels or signals that also need to be processed in the SL BWP or SL resource pool, the terminal selects the processing method of stopping SL-PRS processing.

[0175] In one possible implementation, when transmitting or measuring the SL positioning reference signal within the SL BWP or SL resource pool, the method further includes:

[0176] Transmit a first signal and / or a first channel on the SL BWP or SL resource pool, wherein the symbol of the transmitted first signal and / or first channel does not overlap with the transmitted SL positioning reference signal, or the slot of the transmitted first signal and / or first channel does not overlap with the slot of the transmitted SL positioning reference signal.

[0177] In the embodiments of this application, when processing SL-PRS in the SL BWP or SL resource pool, if there are other channels or signals that also need to be processed in the SL BWP or SL resource pool, the terminal selects the processing method of processing the other channels or signals if they do not overlap with the SL-PRS symbols or slots.

[0181] In this embodiment of the application, when SL-PRS is processed in a dedicated BWP or dedicated resource pool, if there are other channels or signals with higher priority that also need to be processed in the dedicated BWP or dedicated resource pool, the terminal selects to stop processing SL-PRS.

[0182] (2) If a first signal and / or a first channel with a priority higher than or equal to the SL positioning reference signal are transmitted on the target resource, the terminal stops transmitting or measuring the SL positioning reference signal.

[0183] In this embodiment of the application, when SL-PRS is processed in a dedicated BWP or dedicated resource pool, if there are other channels or signals with higher priority that also need to be processed in the dedicated BWP or dedicated resource pool, the terminal selects to stop processing SL-PRS.
