[0053] In some embodiments, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0054] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function. The network device 110 and the terminal device 120 may be the specific devices described above and will not be described in detail here. The communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0055] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

The first communication device can be a terminal device, such as a mobile phone, machine facilities, customer premises equipment (CPE), industrial equipment, vehicles, etc.; the second communication device can be a peer communication device of the first communication device, such as a network device, mobile phone, industrial equipment, vehicles, etc. In the embodiments of the present application, the first communication device can be a terminal device, and the second communication device can be a network device (i.e., uplink communication or downlink communication); alternatively, the first communication device can be a first terminal, and the second communication device can be a second terminal (i.e., sideline communication).

[0057] The terms used in the embodiments of this application are intended only to explain the specific embodiments of this application and are not intended to limit this application. The terms "first," "second," "third," and "fourth," etc. in the specification and claims of this application and the accompanying drawings are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions.

For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0059] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0060] In the embodiments of the present application, "pre-definition" or "pre-configuration" may be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (e.g., a terminal device and a network device). The present application does not limit the specific implementation method. For example, pre-definition may refer to information defined in a protocol.

[0061] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communications field, for example, it may be an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or a protocol related to other communications systems. The present application does not limit the protocol type.

[0062] To facilitate a better understanding of the embodiments of the present application, the sidelink positioning related to the present application is explained.

[0063] As a supplement to the traditional 5G positioning that relies on terminals and gNB (TRP), sidelink positioning additionally utilizes the reference signal measurement results between terminals to complete positioning. For sidelink positioning, the reference signal should be sent and measured in the sidelink specified frequency band. The measurement results should reflect the positioning reference variables that have actual physical meaning in space, such as the relative distance and relative angle between terminals. After triggering sidelink positioning, the terminal with positioning requirements first needs to find a suitable anchor device through network allocation or its own measurement of surrounding signals, and then obtain the positioning measurement results by measuring the reference signal sent by the anchor device and / or the anchor device measuring the reference signal sent by the terminal with positioning requirements, and derive the positioning results.

[0064] In some embodiments, the sidelink positioning process in an out-of-coverage communication scenario is shown in Figures 2 and 3, where Figure 2 is a positioning process based on a UE with positioning requirements sending a sidelink positioning reference signal, and Figure 3 is a positioning process based on an anchor UE sending a sidelink positioning reference signal.

[0065] As can be seen from FIG2 and FIG3 , when the target terminal is required to perform measurement to obtain a positioning result, the target terminal first needs to obtain sidelink positioning reference signals (SL-PRS) from each anchor terminal.

[0066] To facilitate a better understanding of the embodiments of the present application, the configuration of downlink positioning reference signals (DL-PRS) related to the present application is described.

[0067] 5G NR introduces a new reference signal, called positioning reference signals (PRS). PRS has a high resource element (RE) density and better correlation properties than reference signals such as phase tracking reference signal (PT-RS) and sounding reference signal (SRS). The monitorability of PRS is achieved through a concept called muting. With PRS muting, multiple cells transmit PRS in a coordinated manner by muting the relevant PRS transmission opportunities to avoid interference from neighboring cells.

[0068] One or more downlink PRS positioning frequency layers may be configured for the UE. A PRS positioning frequency layer is defined as a set of PRS resource sets, and each PRS resource set is defined as a set of PRS resources.

[0069] In some embodiments, all PRS resource sets defined in the PRS positioning frequency layer are configured with the following common parameters:

[0070] Subcarrier Spacing: The subcarrier spacing of all PRS resource sets in the PRS positioning frequency layer, configured as 15kHz, 30kHz, 60kHz, or 120kHz. The subcarrier spacing in a PRS resource set is set using the SubcarrierSpacing attribute of the nrCarrierConfig field.

[0071] The cyclic prefix of all PRS resource sets in the PRS location frequency layer is configured as "normal" or "extended". The cyclic prefix of the PRS resource set is set using the CyclicPrefix attribute corresponding to the NR carrier configuration (nrCarrierConfig) field.

[0072] PRS point A: The absolute frequency of a reference resource block or common resource block. The lowest subcarrier of this reference resource block is called PRS point A. 5G NR defines the PRS frequency resource allocation relative to PRS point A.

[0073] In some embodiments, all PRS resource sets defined in the PRS positioning frequency layer are configured with the following dedicated parameters:

[0074] PRS slot configuration, PRS muting configuration, PRS time and frequency domain allocation, frequency domain allocation of PRS resources at RE granularity, and PRS sequence ID.

[0075] In some embodiments, the PRS slot configuration includes:

[0076] PRS resource set period (PRSResourceSetPeriod): the time slot period and offset of the PRS resource set (based on 0);

[0077] PRS Resource Offset (PRSResourceOffset): The time slot offset of each PRS resource relative to the time slot offset of the PRS resource set (based on 0);

[0078] PRS Resource Repetition: The repetition factor of all PRS resources in the PRS resource set;

[0079] PRS Resource Time Gap: The time slot offset between two consecutive repetition indices of all PRS resources in a PRS resource set.

[0080] For example, Figure 4 shows an example of a PRS resource set with two PRS resources. The PRS resource set period is 10 slots, and the PRS resource set offset is 3 slots (zero-based). The first PRS resource offset is 1 slot, and the second PRS resource offset is 4 slots. The PRS resource repetition factor is 2 (meaning each PRS resource is repeated twice in each PRS source set instance), and the PRS resource time interval is 2 (meaning an offset of 2 slots).

[0081] In some embodiments, a PRS resource instance is silenced. Specifically, as shown in FIG5 , all PRS resources in the PRS resource instance are silenced, wherein one PRS resource instance corresponds to one PRS resource set period.

[0082] In some embodiments, the PRS resource repetition indices are muted. Specifically, as shown in FIG6 , it is controlled whether each PRS resource transmission in a PRS resource instance needs to be muted.

[0083] In some embodiments, as shown in Figures 7 and 8, for PRS time domain and frequency domain allocation, each PRS resource in the PRS resource set is allocated the number of consecutive orthogonal frequency-division multiplexing (OFDM) symbols in the time slot; the starting OFDM symbol (based on 0) of each PRS resource in the PRS resource set is defined relative to the first OFDM symbol (symbol #0) of the time slot; Num RB: the number of physical resource blocks (PRBs) allocated for all PRS resources in the PRS resource set; resource block (RB) offset: the starting PRB index (based on 0) of all PRS resources in the PRS resource set, which is defined relative to the carrier resource grid and is the offset relative to Common Resource Block 0 (CRB 0).

[0084] In some embodiments, the frequency domain allocation of PRS resources at RE granularity includes:

[0085] Comb Size: The RE density of all PRS resources in a PRS resource set. For example, if the value is configured as i∈{2,4,6,12}, each i-th RE in a PRB is allocated to a PRS.

[0086] RE offset: The RE offset (0-based) starts in the first OFDM symbol of each PRS resource in the PRS resource set.

[0087] For example, as shown in FIG9 , consider that the number of OFDM symbols allocated for PRS resources is 6, the starting OFDM symbol of the PRS resource configuration is 3 (based on 0), the PRS comb size is 4, and the RE offset in the first OFDM symbol is 2 (based on 0).

[0088] In some embodiments, a PRS sequence identifier (PRS sequence ID) is generated based on a pseudo-random sequence c(i) using a 31-order Gold sequence. The PRS sequence identifier (PRS sequence ID) is related to a sequence ID given by a higher layer and a time-frequency domain position of sequence mapping.

[0089] In summary, when the network configures DL-PRS for a terminal, in order to clearly let the terminal know the time and frequency domain location of the target DL-PRS and what sequence to use for detection, the network needs to send all the above configuration information to the terminal. This configuration information is also configured separately by each Transmission Reception Point (TRP) and summarized in the Location Management Function (LMF) entity.

[0090] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0091] In sidelink positioning, if the sidelink positioning server uses unicast to configure the SL-PRS configuration that each anchor terminal / target terminal should use, it will take a lot of time for each anchor terminal / target terminal to obtain its corresponding SL-PRS, increasing the positioning delay.

[0092] Based on the above problems, the present application proposes a scheme for configuring or indicating the configuration information of the side positioning reference signal, which can configure or indicate the configuration information of the side positioning reference signal by broadcasting, thereby realizing low-latency configuration of the side positioning reference signal, thereby improving the efficiency of side positioning.

[0093] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0094] FIG10 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG10 , the wireless communication method 200 may include at least part of the following contents:

[0095] S210: A first communication device broadcasts first information, where the first information includes configuration information of a sideways positioning reference signal.

[0096] S220: The second communication device receives the broadcasted first information.

[0097] In an embodiment of the present application, the first communication device can configure or indicate the configuration information of the side positioning reference signal by broadcasting, thereby achieving low-latency configuration of the side positioning reference signal, thereby improving the efficiency of side positioning.

[0098] In some embodiments, the first communication device is a terminal device, or the first communication device is a network device. Optionally, the network device can be one of the following: a base station or access network device, a LMF entity, or an Access and Mobility Management Function (AMF) entity.

[0099] In some embodiments, the second communication device is an anchor device or a terminal device with positioning requirements.

[0100] In the embodiment of the present application, the anchor terminal may be a device that assists in terminal positioning and can send a reference signal or measure a received reference signal on a sidelink. The anchor terminal and the terminal device may communicate via a PC5 interface.

[0101] In the embodiments of the present application, the "anchor terminal" may also be referred to as an "anchor device" or a "roadside unit (RSU)" or an "other terminal" or a "relay terminal", which is not limited in the present application.

[0102] In some embodiments, the side positioning reference signal may be an SL-PRS, or other reference signals used for side positioning, which is not limited in the embodiments of the present application.

[0103] In some embodiments, the first information may be carried by a system broadcast message, or the first information may be carried by other broadcast messages, which is not limited in the embodiments of the present application.

[0104] Because the broadcast method is used, if different second communication devices select the same sidelink positioning reference signal configuration, sidelink positioning reference signal transmission collisions may occur between the second communication devices. In this embodiment of the application, the possibility of transmission collisions between the sidelink positioning reference signal configurations selected by the second communication devices can be reduced by grouping.

[0105] In some embodiments, the configuration information of the sidelink positioning reference signal is determined by monitoring the sidelink positioning reference signal, or the configuration information of the sidelink positioning reference signal is determined based on the sidelink positioning reference signal that has been used. That is, the first communication device can determine the configuration information of the sidelink positioning reference signal (SL-PRS) by monitoring the sidelink positioning reference signal (SL-PRS). Alternatively, the first communication device can determine the configuration information of the SL-PRS by receiving an SL-PRS obtained from the LMF entity that does not conflict with the SL-PRS already in use by other surrounding terminals.

[0106] In some embodiments, the second communication device transmits a sideways positioning reference signal for sideways positioning according to the configuration information of the sideways positioning reference signal. That is, the anchor terminal or the terminal device with positioning requirements applies the SL-PRS configuration obtained through broadcasting to perform SL-PRS transmission.

[0107] In some embodiments, the sidelink positioning reference signal configuration information may include part or all of the above-mentioned DL-PRS configuration. It is only necessary to adaptively change the downlink parameters in the above-mentioned DL-PRS configuration to sidelink parameters. Of course, the sidelink positioning reference signal configuration information may also include other sidelink positioning reference signal parameter information.

[0108] In some embodiments, the sidelink positioning reference signal configuration information includes M sets of sidelink positioning reference signal resource pool configurations; wherein the M sets of sidelink positioning reference signal resource pool configurations are determined based on a first classification rule for devices participating in sidelink positioning, where M is a positive integer. That is, the first communications device can classify devices participating in sidelink positioning (e.g., anchor terminals or terminal devices with positioning requirements) and configure corresponding sidelink positioning reference signal resource pools.

[0109] In some embodiments, the device involved in the side positioning includes but is not limited to at least one of the following:

[0110] Anchor terminal, base station, terminal equipment with positioning requirements.

[0111] In some embodiments, each device category classified based on the first classification rule corresponds to a set of resource pool configurations for sidetrack positioning reference signals. Specifically, for example, devices participating in sidetrack positioning can be classified into S categories of devices based on the first classification rule, and each category of device corresponds to a set of resource pool configurations for sidetrack positioning reference signals, where S is a positive integer and S≤M.

[0112] In some embodiments, the correspondence between each type of device divided based on the first classification rule and the resource pool configuration of the sidelink positioning reference signal is agreed upon by a protocol, or the correspondence between each type of device divided based on the first classification rule and the resource pool configuration of the sidelink positioning reference signal is indicated by a dedicated signaling configuration or a broadcast message.

[0113] In some embodiments, the first classification rule includes classification based on first identification information of a device participating in sidewalk positioning.

[0114] In some embodiments, the first identification information includes but is not limited to one of the following:

[0115] Cell Radio Network Temporary Identity (C-RNTI), Temporary Mobile Subscriber Identity (TMSI).

[0116] For example, the first classification rule is to classify based on the C-RNTI or TMSI of the terminal device. For example, based on the terminal's C-RNTI mod 10, the terminals are divided into 10 groups, and each group of terminals can select to use one sidelink positioning reference signal resource from the resource pool of the sidelink positioning reference signal corresponding to the terminals in the group. For another example, based on the terminal's TMSI mod 10, the terminals are divided into 10 groups, and each group of terminals can select to use one sidelink positioning reference signal resource from the resource pool of the sidelink positioning reference signal corresponding to the terminals in the group.

[0117] In some embodiments, the first classification rule includes classification based on the geographical location of the device participating in the sidewalk positioning.

[0118] For example, the first classification rule is to classify the terminal device based on its geographical location. For example, if the coverage area of ​​the gNB is divided into 10 areas, the terminal in each area can select a sidelink positioning reference signal resource from the sidelink positioning reference signal resource pool corresponding to the area.

[0119] In some embodiments, the first information includes first indication information, which is used to indicate the first classification rule. That is, the first communications device may inform the second communications device via broadcast to perform classification according to the first classification rule, thereby determining a corresponding sidelink positioning reference signal resource pool, selecting a sidelink positioning reference signal resource from the sidelink positioning reference signal resource pool, and transmitting the sidelink positioning reference signal.

[0120] In some embodiments, the first communication device receives second information sent by the second communication device;

[0121] The second information is used to indicate the index of the sidelink positioning reference signal resource selected by the second communication device in the corresponding sidelink positioning reference signal resource pool, and the sidelink positioning reference signal resource pool corresponding to the second communication device is determined based on the resource pool configuration of the sidelink positioning reference signal corresponding to the category to which the second communication device belongs.

[0122] That is, the second communication device can be classified based on the first classification rule, and select a sidelink positioning reference signal resource from the resource pool configured by the sidelink positioning reference signal resource pool configuration corresponding to the classification to which the second communication device belongs, and report the index of the selected sidelink positioning reference signal resource.

[0123] In some embodiments, the sidelink positioning reference signal resource selected by the second communication device is determined based on monitoring the sidelink positioning reference signal, or the sidelink positioning reference signal resource selected by the second communication device is determined based on the configuration information of the sidelink positioning reference signal indicated by other devices. That is, the second communication device can monitor or observe through the configuration information of the sidelink positioning reference signal indicated by other devices whether the sidelink positioning reference signal resource selected by itself is occupied. If the result is not occupied, the sidelink positioning reference signal is sent; if the result is occupied, the SL-PRS is not sent, and the sidelink positioning reference signal resource is re-selected from the corresponding resource pool.

[0124] Therefore, in an embodiment, the second communication device may choose to monitor or observe the SL-PRS selected by other devices to reduce the possibility of SL-PRS collision. Further, the number of terminals where SL-PRS may occur may be limited to reduce the possibility of SL-PRS collision and the monitoring or observation time.

[0125] In some embodiments, the second information may be carried by a broadcast message.

[0126] In some embodiments, the second information can be carried by one of the following: Radio Resource Control (RRC) signaling, uplink control information (UCI), media access control layer control element (MAC CE), sidelink control information (SCI), PC5-RRC.

[0127] For example, as shown in FIG11 , a first communication device may broadcast SL-PRS configuration information (M sets of SL-PRS resource pool configurations) and corresponding grouping information (first classification rule) as auxiliary data. Specifically, an anchor terminal may receive the broadcasted auxiliary information, monitor or observe SL-PRSs selected by other devices, and select an SL-PRS resource from a configured SL-PRS resource pool based on the grouping information and the selected SL-PRS resource. The anchor terminal notifies the index of the selected SL-PRS resource and transmits the SL-PRS on the selected SL-PRS resource. Specifically, a terminal device with positioning requirements may receive the broadcasted auxiliary information, monitor or observe SL-PRSs selected by other devices, and select an SL-PRS resource from a configured SL-PRS resource pool based on the grouping information and the selected SL-PRS resource. The anchor terminal notifies the index of the selected SL-PRS resource and transmits the SL-PRS on the selected SL-PRS resource.

[0128] In some embodiments, the sideline positioning reference signal configuration information includes N sideline positioning reference signal configurations, where each of the N sideline positioning reference signal configurations corresponds to a device participating in sideline positioning, N is a positive integer, and N ≥ 2. That is, by bundling the SL-PRS configuration with the identifier of the device participating in sideline positioning, the SL-PRS configuration is conveniently sent to the anchor terminal or the terminal device with positioning requirements via broadcast.

[0129] In some embodiments, different devices participating in the sideline positioning are distinguished by second identification information. Optionally, the second identification information includes at least one of the following: a source ID and a destination ID.

[0130] Therefore, in the embodiment of the present application, the first communication device can configure or indicate the configuration information of the sideline positioning reference signal by broadcasting, thereby achieving low-latency configuration of the sideline positioning reference signal, thereby improving the efficiency of sideline positioning. This avoids the need to establish a unicast communication link to send the SL-PRS, thus saving the delay overhead of the signaling process.

[0131] Furthermore, the possibility of collision of SL-PRS configurations selected by the terminal and the monitoring range are reduced by grouping, and the possibility of SL-PRS collision of the terminal is further reduced by using monitoring before sending.

[0132] Furthermore, by bundling the SL-PRS configuration with the identification (ID) of the second communication device, the SL-PRS configuration can be conveniently sent to the second communication device in a broadcasting form.
