Indication method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 28, 2023, with application number 202311295287.0 and application name “Indication Method and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an indication method and related devices. Background Art

[0003] In the sidelink communication system, sidelink resource scheduling supports three modes: dynamic scheduling, semi-static scheduling, and periodic scheduling. With the introduction of positioning functionality in the sidelink communication resource pool, users can simultaneously transmit data and sidelink positioning reference signals within a single time slot. For sidelink resources, how users determine whether to transmit sidelink positioning reference signals on these resources is a question worth considering.

[0004] Summary of the Invention

[0005] The present application provides an indication method and related apparatus, configured for a terminal device to receive first information from a network device, the first information indicating whether a first periodic resource supports transmission of a sidelink positioning reference signal. This enables the terminal device to determine whether the first periodic resource can be used for transmission of a sidelink positioning reference signal.

[0006] The first aspect of the present application provides an indication method, which is executed by a terminal device. The terminal device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module, or control unit in the aforementioned device or apparatus, and the present application does not limit this. It should be noted that in the present application, when referring to a terminal device, it may refer to the terminal device itself, or to a chip, functional module or integrated circuit in the terminal device that completes the method provided by the present application, and the present application does not limit this. In the first aspect and its possible implementation methods, the method is described as being executed by a terminal device. The method includes:

[0007] The terminal device receives first information from a network device, the first information indicating whether a first periodic resource supports transmission of a sidelink positioning reference signal, the first periodic resource being a sidelink resource configured by the network device for the terminal device; the terminal device determines whether the first periodic resource supports transmission of a sidelink positioning reference signal based on the first information. Thus, it can be seen that the terminal device receives first information from the network device, the first information indicating whether the first periodic resource supports transmission of a sidelink positioning reference signal. This enables the terminal device to determine whether the first periodic resource can be used for transmission of a sidelink positioning reference signal.

[0008] Based on the first aspect, in a possible implementation, the method further includes: the terminal device receives second information from the network device, and the second information indicates whether the first periodic resource supports data transmission. In this implementation, the terminal device may also receive the second information to determine whether the first periodic resource supports data transmission. Optionally, the first information and the second information may be the same information, and different values ​​of the information may indicate different meanings. The information may indicate that the first periodic resource supports the transmission of a sidelink positioning reference signal, or supports the first periodic resource to support the transmission of data. That is, the first periodic resource either supports the transmission of a sidelink positioning reference signal or supports the transmission of data.

[0009] Based on the first aspect, in a possible implementation, the method further includes: the terminal device receives third information from the network device, and the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data at the same time. That is, it can be understood that the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time slot or the same time domain symbol. Optionally, the first information, the second information and the third information can be the same information, and the three different values ​​of the information can indicate three different meanings. The information can indicate that the first periodic resource supports the transmission of the sidelink positioning reference signal, or supports the first periodic resource to support the transmission of data, or indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time slot or the same time domain symbol. That is to say, the first periodic resource either supports the transmission of the sidelink positioning reference signal, or supports the transmission of data, or supports the simultaneous transmission of the sidelink positioning reference signal and data.

[0010] The second aspect of the present application provides an indication method, which is performed by a network device. The network device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and the present application does not limit this. It should be noted that in the present application, when referring to a network device, it may refer to the network device itself, or to a chip, functional module or integrated circuit in the network device that completes the method provided in the present application, and the present application does not limit this. In the second aspect and its possible implementation methods, the method is described as being performed by a network device. The method includes:

[0011] The network device determines first information, where the first information indicates whether a first periodic resource supports transmission of a sidelink positioning reference signal, and the first periodic resource is a sidelink resource configured by the network device for the terminal device. The network device sends the first information to the terminal device. Therefore, it can be seen that the network device sends the first information to the terminal device, where the first information indicates whether the first periodic resource supports transmission of a sidelink positioning reference signal. This enables the terminal device to determine whether the first periodic resource can be used for transmission of a sidelink positioning reference signal.

[0012] Based on the second aspect, in a possible implementation, the method further includes: the network device sends second information to the terminal device, and the second information indicates whether the first periodic resource supports data transmission. In this implementation, the network device also sends the second information. This facilitates the terminal device to determine whether the first periodic resource supports data transmission. Optionally, the first information and the second information can be the same information, and different values ​​of the information can indicate different meanings. The information can indicate that the first periodic resource supports the transmission of a sidelink positioning reference signal, or supports the first periodic resource to support data transmission. That is, the first periodic resource either supports the transmission of a sidelink positioning reference signal or supports the transmission of data.

[0013] Based on the second aspect, in a possible implementation, the method further includes: the network device sends third information to the terminal device, and the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data at the same time. That is, it can be understood that the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time slot or the same time domain symbol. Optionally, the first information, the second information and the third information can be the same information, and the three different values ​​of the information can indicate three different meanings. The information can indicate that the first periodic resource supports the transmission of the sidelink positioning reference signal, or supports the first periodic resource to support the transmission of data, or indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time slot or the same time domain symbol. That is to say, the first periodic resource either supports the transmission of the sidelink positioning reference signal, or supports the transmission of data, or supports the simultaneous transmission of the sidelink positioning reference signal and data.

[0014] Based on the first aspect or the second aspect, in a possible implementation, the first information is carried in the configuration information of the first periodic resource, or the first information is carried in the resource pool configuration information. For example, the first information is carried in the configuration information of the first periodic resource, which can not only realize the scheduling of the first periodic resource, but also realize the indication of whether the first periodic resource supports the transmission of the side link positioning reference signal. Reduce the signaling indication overhead and maintain the scheduling flexibility of resources. On the other hand, there is no need to define new signaling to carry the first information, so as to achieve compatibility with the current scheduling scheme of periodic resources and minimize the implementation complexity on the terminal device side. For the implementation method in which the first information is carried in the resource pool configuration information, in the process of realizing the configuration of the resource pool, the indication of whether the periodic resources of the resource pool support the transmission of the side link positioning reference signal is conducive to reducing the signaling indication overhead. There is no need to define new signaling to carry the first information, and the solution is more practical.

[0015] Based on the first aspect or the second aspect, in a possible implementation manner, the first information is the first field in the configuration information of the first periodic resource, or the first field in the resource pool configuration information.

[0016] Based on the first aspect or the second aspect, in one possible implementation, when the value of the first field is a first value, it indicates that the first periodic resource supports transmission of a sidelink positioning reference signal; when the value of the first field is a second value, it indicates that the first periodic resource does not support transmission of a sidelink positioning reference signal. In this way, different values ​​of the first field are used to indicate whether the first periodic resource supports transmission of a sidelink positioning reference signal.

[0017] Based on the first aspect or the second aspect, in one possible implementation, the first periodic resource is a periodic resource of a shared resource pool. In the shared resource pool, resources can be used for transmission of a sidelink positioning reference signal. Whether the first periodic resource can support the sidelink positioning reference signal is determined by a network device. Therefore, the network device of the present application indicates, through the first information, whether the first periodic resource supports transmission of the sidelink positioning reference signal.

[0018] Based on the first aspect or the second aspect, in a possible implementation manner, the first periodic resource is a sidelink configured grant Type 1 (sidelink configured grant Type 1, SL CG Type 1) resource.

[0021] A processing module is used to determine whether the first periodic resource supports the transmission of a sidelink positioning reference signal based on the first information.

[0022] Based on the third aspect, in a possible implementation manner, the transceiver module is further used to: receive second information from a second communication device, where the second information indicates whether the first periodic resource supports data transmission.

[0028] Based on the fourth aspect, in a possible implementation manner, the transceiver module is further used to: send third information to the first communication device, where the third information indicates whether the first periodic resource supports the transmission of a sidelink positioning reference signal and data at the same time.

[0029] Based on the third aspect or the fourth aspect, in a possible implementation manner, the first information is carried in the configuration information of the first periodic resource, or the first information is carried in the resource pool configuration information.

[0030] Based on the third aspect or the fourth aspect, in a possible implementation manner, the first information is the first field in the configuration information of the first periodic resource, or the first field in the resource pool configuration information.

[0031] Based on the third aspect or the fourth aspect, in one possible implementation, when the value of the first field is the first value, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is the second value, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0036] Optionally, the processor is integrated with the memory.

[0059] The following describes some scenarios where this application is applicable in conjunction with Figures 1 to 3.

[0060] FIG1 is a schematic diagram of the structure of a communication system according to an embodiment of the present application. Referring to FIG1 , the communication system includes a terminal device 101, a terminal device 102, an access network device 103, an access and mobility management function (AMF) 104, and a location management function (LMF) 105.

[0061] Optionally, the terminal device 101 and the terminal device 102 may be connected via an interface. The access network device 103 and the AMF 104 may be connected via an interface, and the AMF 104 and the LMF 105 may be connected via an interface.

[0062] For example, the terminal device 101 and the terminal device 102 can be connected through the proximity communication 5 (prose communication 5, PC5) interface. The terminal device 101 and the terminal device 102 are respectively connected to the access network device 103 through the NR-Uu interface, and the access network device 103 is connected to the AMF 104 through the NG-C interface. The AMF 104 and the LMF 105 are connected through the NL1 interface. The NR-Uu interface is the communication interface between the terminal device and the access network device. The NG-C interface is the control plane interface between the access network and the core network. The NL1 interface is the communication interface between the AMF and the LMF. The NR-Uu interface is the communication interface between the terminal device and the access network device. The NG-C interface is the control plane interface between the access network and the core network. The NL1 interface is the communication interface between the AMF and the LMF.

[0063] Figure 1 above merely illustrates an example of a communication system including terminal device 101, terminal device 102, and access network device 103. In actual applications, the communication system may include at least two terminal devices and at least one access network device, which is not specifically limited in this application. The technical solution of this application may be implemented between terminal device 101 and access network device 103. Alternatively, terminal device 101 and terminal device 102 may communicate and / or locate each other using the first periodic resource configured by access network device 103.

[0064] FIG2 is another structural diagram of a communication system according to an embodiment of the present application. The communication system includes a terminal device 201, a terminal device 202, and an access network device 203. Optionally, the communication system further includes an LMF 204. Optionally, the terminal device 201 is within the signal coverage of the access network device 203, while the terminal device 202 is not within the signal coverage of the access network device 203. The technical solution of the present application can be implemented between the terminal device 201 and the access network device 203. Optionally, the terminal device 201 and the terminal device 202 can communicate and / or locate each other through the first periodic resource configured by the access network device 103.

[0065] FIG3 is another structural diagram of the communication system of an embodiment of the present application. Referring to FIG3 , the communication system includes a terminal device 301, a roadside unit (RSU) 302, an RSU 303, an RSU 304, and an access network device 305.

Optionally, the terminal device 301 and the RSU can communicate and / or locate each other via the first periodic resource configured by the access network device 305.

[0066] It should be noted that, in the communication system shown in FIG3 , the form of the RSU is merely an example and does not constitute a limitation on the RSU in this application.

[0067] It should be noted that an RSU is a roadside unit deployed on the roadside that supports sidelink communication and positioning protocols and provides wireless communication capabilities for terminal devices. An RSU can be a roadside station, access point, or sidelink device in various forms. For access network devices, an RSU is a terminal device. For terminal devices, an RSU can act as an access network device.

[0068] In the communication systems shown in Figures 1 and 2 above, LMF is the name of the current communication system. In future communication systems, the name of the LMF may change as the communication system evolves, and this application does not limit the name of the LMF. For example, the LMF can be called a positioning device, which is used to calculate the location of the terminal device. In current or future communication systems, any functional network element with other names that have similar functions to the LMF can be understood as a positioning device.

[0069] The communication system applicable to the present application shown above is only an example. In actual application, the present application can also be applied to other communication systems with positioning requirements, and the present application does not make specific limitations. The above examples do not limit the technical solutions of the present application.

[0070] The following introduces the terminal equipment and network equipment involved in this application.

The wireless terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0072] Terminal equipment, also known as user equipment (UE), mobile station (MS), customer premise equipment (CPE), or mobile terminal (MT), is a device that includes wireless communication capabilities (providing voice / data connectivity to users). For example, a handheld device or vehicle-mounted device with wireless connectivity. Currently, some examples of terminal equipment include: mobile phones, tablets, laptops, PDAs, trains, cars, drones, airplanes, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in the Internet of Vehicles (IoV), wireless terminals in self-driving systems (e.g., drones, vehicles), wireless terminals in smart grids, wireless terminals in transportation safety, and wireless terminals in smart cities. For example, wireless terminals in the IoV can be vehicle-mounted devices, complete vehicle equipment, vehicle-mounted modules, vehicles, etc. The wireless terminal in industrial control can be a robot, etc. Alternatively, the terminal device can be a terminal device in the fifth generation (5G) network or a terminal device in a future evolved public land mobile network (PLMN). Optionally, the terminal device can communicate with multiple access network devices of different technologies. For example, the terminal device can communicate with an access network device that supports long term evolution (LTE), or with an access network device that supports 5G, or can be dual-connected with an access network device that supports LTE and an access network device that supports 5G. This application is not limited.

[0073] In the present application, the device for realizing the function of the terminal device may be a terminal device, or a device that can support the terminal device to realize the function. For example, a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The device can be installed in the terminal device or can be used in combination with the terminal device. For example, the terminal device can also be a chip, a module or a control unit in the various possible devices or apparatuses shown above, and this application does not limit this. In the technical solution provided in the present application, the technical solution provided in the present application is described by taking the device for realizing the function of the terminal device as a terminal device, and the terminal device as a UE as an example.

[0074] In this application, the chip system can be composed of chips, or can include chips and other discrete devices.

[0075] A network device may be a device in a wireless network. For example, a network device may be a device deployed in a radio access network that provides wireless communication capabilities for terminal devices. For example, a network device may be a radio access network (RAN) node that connects a terminal device to a wireless network. The network device may also be referred to as an access network device, a RAN entity, an access node, a network node, or a communication device.

[0076] Specifically, the network device may be an access network device for a cellular system related to the 3rd Generation Partnership Project (3GPP). For example, a 4G communication system, a 5G communication system, or a 6G communication system. The network device may also be an access network device in an open access network (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device may be an access network device in a communication system obtained by integrating two or more of the above communication systems.

[0077] The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a transmission and receiving point (TRP), and may also be a network device in a 5G mobile communication system. For example, a next generation NodeB (gNB), a TRP, or a TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the network device may also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device can also be a server, a wearable device, a vehicle, or an on-board device. For example, the access network device in the V2X technology can be a road side unit (RSU).

[0078] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), a centralized unit control plane (CU-CP) may also be called an O-CU-CP or an open CU-CP, a centralized unit user plane (CU-UP) may also be called an O-CU-UP or an open CU-UP, and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0079] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0080] Table 1

[0081] Optionally, the network device in this application may be one or more network elements shown in Table 1 above.

[0082] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0083] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0084] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0085] The CU-CP can interact with the network elements in the core network for implementing control plane functions. The network elements in the core network for implementing control plane functions can be access and mobility function network elements, such as the access and mobility management function (AMF) in the 5G system. The access and mobility function network element is responsible for mobility management in the mobile network, such as location update of terminal equipment, registration network of terminal equipment, switching of terminal equipment, etc. The CU-UP can interact with the network elements in the core network for implementing user plane functions. The network elements in the core network for implementing user plane functions, such as the user function (UPF) in the 5G system, are responsible for forwarding and receiving data in the terminal equipment.

[0086] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0087] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0088] In the present application, the device for realizing the function of the network device may be a network device, or a device that can support the network device to realize the function. For example, a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module, the device can be installed in the network device or can be used in combination with the network device. For example, the network device may be the device or apparatus shown above, or it may be a component (for example, a chip), module, or unit in the device or apparatus shown above, and this application does not limit this. In the technical solution provided in the present application, the technical solution provided in the present application is described by taking the device for realizing the function of the network device as a network device, and the network device as a base station as an example.

[0089] In order to facilitate understanding of the technical solution of this application, some technical terms involved in this application are first introduced.

[0090] Resource pool: The terminal device can use the resources in the sidelink resource pool for data transmission. A resource pool can be configured with one or more consecutive physical resource blocks (PRBs) (or resource blocks (RBs)) in the frequency domain and one or more time slots in the time domain, where multiple time slots can be continuous or non-continuous.

[0091] To facilitate understanding of resource pools, the following describes resource pools in a sidelink system, using Figure 4 as an example. Referring to Figure 4 , a portion of a carrier bandwidth used for sidelink spectrum is called a sidelink bandwidth part (SL BWP). Multiple resource pools can be defined within the SL BWP. Figure 4 illustrates five resource pools (resource pool #1, resource pool #2, resource pool #3, resource pool #4, and resource pool #5).

[0092] Each resource pool can be configured with independent channels such as the PSCCH and PSSCH, with independent sensing and resource allocation. A resource pool can be configured with multiple contiguous RBs in the frequency domain, with a certain number of contiguous RBs forming a subchannel. Resource allocation and data transmission can be performed on a subchannel basis. This means that a terminal device can occupy one or more subchannels for data transmission. In other words, the minimum unit granularity for transmitting or receiving sidelink data by a terminal device is called a subchannel. The number of RBs in a subchannel can be 10, 12, 15, 20, 25, 50, 75, or 100.

[0093] Optionally, in a sidelink communication system, the resource pool used for communication may be referred to as a communication resource pool, and the resource pool used for positioning may be referred to as a positioning resource pool. Positioning functionality may be further incorporated into the communication resource pool, and thus the communication resource pool incorporating positioning functionality may be referred to as a shared resource pool. Alternatively, a resource pool supporting both communication and positioning functionality may be referred to as a shared resource pool.

[0094] In the sidelink communication system, resources can be divided into three types: dynamic resources, semi-static resources and periodic resources.

[0095] Dynamic resources are also called dynamic grant (DG) resources or sidelink dynamic grant (SL DG) resources, that is, one or more non-periodic resources scheduled by the base station through DCI.

[0096] Semi-static resources are also called configured grant type 2 (CG Type 2) resources, or sidelink configured grant type 2 (SL CG Type 2) resources. The base station pre-configures parameters such as resource period and number of transmissions, but the terminal device cannot send data on the semi-static resources. It can only send data on the DCI-scheduled resources after receiving the DCI sent by the base station. For activated semi-static resources, the base station can also deactivate them through DCI, and the terminal device needs to stop sending data on the deactivated resources. Semi-static resources can also be called semi-periodic resources or semi-persistent resources. This application does not limit them specifically. Semi-static resources, semi-periodic resources and semi-persistent resources have the same meaning and can be used interchangeably.

[0097] Periodic resources are also known as configured grant type 1 (CG Type 1) resources or sidelink configured grant type 2 (SL CG Type 1) resources. The base station configures these resources through higher-layer signaling. For example, the base station configures parameters such as the resource period through RRC signaling. After configuration, the terminal device can send data on the periodic resources without the base station activating or deactivating the periodic resources through DCI.

[0098] Resources refer to the time-frequency resources in a resource pool. These resources include time-domain resources and frequency-domain resources. Time-domain resources can be represented by symbols, slots, sub-slots, mini-slots, partial slots, sub-frames, frames, or sensing slots. Frequency-domain resources can be represented by resource elements (REs), resource blocks (RBs), sub-channels, resource pools, bandwidth, bandwidth parts (BWPs), carriers, channels, or interlaces.

[0099] After the positioning function is introduced into the communication resource pool, users can send data and sidelink positioning reference signals simultaneously in one time slot. In a sidelink communication system, for periodic resources, how users determine whether periodic sidelink positioning reference signals can be transmitted in the periodic resources is a question worth considering. The present application provides an indication method and related apparatus for a terminal device to receive first information from a network device, the first information indicating whether the first periodic resource supports the transmission of a sidelink positioning reference signal. For details, please refer to the relevant description of the embodiments below.

[0100] The technical solution of the present application is described below with reference to embodiments.

[0101] FIG5 is a schematic diagram of an embodiment of the indication method of the present application. Referring to FIG5 , the method includes:

[0102] 501. The network device determines first information.

[0103] The first information indicates whether the first periodic resource supports transmission of a sidelink positioning reference signal. For example, the first information is first indication information. The first information is associated with the first periodic resource. The first periodic resource is a sidelink resource configured by the network device for the terminal device.

[0104] Optionally, the first information may also be one or more sidelink positioning reference signal resource index information or resource ID information. The first periodic resource includes a positioning reference signal resource index, indicating that the first periodic resource can send a positioning reference signal on the corresponding sidelink positioning reference signal resource.

[0105] Optionally, the first information may also be configuration parameters related to the sidelink reference signal resource. For example, one or more of a comb fraction, an offset, a number of symbols, and a starting symbol number. The configuration of the first periodic resource includes one or more of the above configuration parameters. The above one or more configuration parameters indicate that the first periodic resource can be used for sidelink positioning reference signal transmission.

[0106] Optionally, the first periodic resource is a periodic resource configured by the network device for the terminal device. Alternatively, the first periodic resource is a periodic resource in a shared resource pool, that is, a type of resource in the shared resource pool.

[0107] Optionally, the first periodic resource is an SL CG Type 1 resource.

[0108] 502. The network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

[0109] In one possible implementation, the first information is carried in the configuration information of the first periodic resource. In this implementation, the first periodic resource may be a periodic resource configured by the network device for the terminal device. Optionally, the configuration information of the first periodic resource is carried in RRC signaling. The configuration information of the first periodic resource may also be referred to as the configuration information of the SL CG Type 1 resource.

[0110] For example, for a terminal device, the high layer indicates that there is a service demand, and the network device can configure the first periodic resource for the terminal device through the RRC signaling of the physical layer. If the data service volume of the terminal device is large or the priority of the data service is high, the first information can indicate that the first periodic resource does not support the transmission of the sidelink positioning reference signal. That is, the first periodic resource can be used for data transmission first. If the data service volume of the terminal device is small or the priority of the data service is low, the first information can indicate that the first periodic resource supports the transmission of the sidelink positioning reference signal.

[0111] Optionally, the first information is the first field in the configuration information of the first periodic resource. The first field may occupy 1 bit, 2 bits, or other lengths, which are not specifically limited in this application.

[0112] For example, when the value of the first field is the first value, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is the second value, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0113] The following describes some possible implementations of the first value and the second value. This application is still applicable to other implementations, and the following implementations do not limit this application.

[0114] Implementation method 1: When the value of the first field is 0, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is 1, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0115] Implementation method 2: When the value of the first field is 1, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is 0, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0116] Implementation method 3: When the value of the first field is true (true), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is false (false), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0117] Implementation method 4: When the value of the first field is enabled, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is disabled, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0118] Optionally, the configuration information of the first periodic resource further includes at least one of the following: a side link configuration grant (SL CG) index, a time domain period of SL transmission, first indication information, an offset number used when deriving the number of hybrid automatic repeat request (HARQ) processes, second indication information, third indication information, fourth indication information, fifth indication information, sixth indication information, or seventh indication information;

[0119] Among them, the first indication information is used to indicate the number of HARQ processes of a specific CG. The second indication information is used to indicate that a transport block (TB) is completed through a maximum of N transmissions, where N is an integer greater than or equal to 1. The third indication information is used to indicate the different possible combinations of three time slots reserved by the terminal device in each cycle of the current CG, the first of the three time slots being a time slot reserved for the terminal device corresponding to the resource reservation index of the first 31 time slots in the future starting from the initial transmission time slot in each cycle of the current CG, and the last two of the three time slots being two time slots reserved for the terminal device corresponding to the resource reservation index of the 33rd time slot to the 496th time slot in the future starting from the initial transmission time slot in each cycle of the current CG. The fourth indication information is used to indicate the number of offset time slots of a time slot in a cycle relative to the current frame. The fifth indication information is used to indicate the starting subchannel index information. The sixth indication information is used to indicate the frequency domain resources occupied by the current CG. The seventh indication information is used to instruct the terminal device to feed back information of an acknowledgement message (ACK) or a negative acknowledgement message (NACK) through a physical uplink control channel (PUCCH) resource.

[0120] A possible format of the configuration information of the first periodic resource is introduced below.

[0121] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first information is the sidelink positioning reference signal indication (sl-PRS-Indicator) information element, and the value of the sidelink positioning reference signal indication information element can be enabled (enable) or disabled (disable). When the value of the sidelink positioning reference signal indication information element is enabled (enable), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is disabled (disable), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. Alternatively, the value of the sidelink positioning reference signal indication information element can be true (true) or false (false). When the value of the sidelink positioning reference signal indication information element is true (true), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is false (false), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first periodic resource of the present application is an SL Type 1 CG resource.

[0122] The sl-ConfigIndexCG-r16 information element indicates the SL CG index. For a terminal device, the network device can configure multiple SL CGs. The sl-PeriodCG-r16 information element indicates the time domain period of SL transmission, in milliseconds (ms), with the minimum time domain period being 100ms and the maximum time domain period being 1000ms. The minimum period and maximum period can be further extended in the future based on actual needs. The sl-NrOfHARQ-Process-r16 information element indicates the number of HARQ processes of a specific CG, and the specific number of HARQ processes falls within the interval (1, 16). The sl-HARQ-ProcID-offset-r16 information element is used to derive the offset number used when deriving the number of HARQ processes, and the specific offset number falls within the range (0, 15). The sl-CG-MaxTransNumList-r16 information element indicates that a TB can be completed through a maximum of N transmissions, which is associated with the channel priority. Usually N is in the range [1, 32]. The sl-TimeResourceCG-Type1-r16 information element indicates the different possible combinations of three time slots reserved by the terminal device in each cycle of the current CG. The first time slot of the three time slots is a time slot reserved for the terminal device corresponding to the resource reservation index (i.e., 0 to 31) of the first 31 time slots in the future starting from the initial transmission time slot in each cycle of the current CG, and the last two time slots of the three time slots are two time slots reserved for the terminal device corresponding to the resource reservation index (i.e., 33 to 496) of the 33rd time slot to the 496th time slot in the future starting from the initial transmission time slot in each cycle of the current CG. The sl-TimeOffsetCG-Type1-r16 information element indicates the offset time slot number of a time slot in a cycle relative to the current frame. The sl-StartSubchannelCG-Type1-r16 information element indicates the starting subchannel index information. The sl-FreqResourceCG-Type1-r16 information element indicates the frequency domain resources currently occupied by the CG. For details, please refer to the relevant introduction of protocol 3.8.212-8.3.1.1. The sl-N1PUCCH-AN-r16 information element instructs the terminal device to feedback ACK or NACK through the PUCCH resource.

[0123] For periodic sidelink positioning reference signal transmission, since resources within a time slot cannot be reused among multiple users, the network device can send first information to the terminal device, indicating that the first periodic resource can be used for sidelink positioning reference signal transmission. This eliminates the need to indicate the time domain symbols, comb fractions, and frequency domain offsets occupied by the sidelink positioning reference signal, thereby saving signaling overhead. Specific sidelink positioning reference signal parameters can be indicated in the sidelink positioning reference signal configuration information of the resource pool.

[0124] It should be noted that, in the format of the configuration information of the first periodic resource, the sidelink positioning reference signal indication element may also be called by other names, which is not specifically limited in this application.

[0125] Another possible format of the configuration information of the first periodic resource is introduced below.

[0126] As can be seen from the format of the configuration information of the first periodic resource described above, the first information is a sidelink positioning reference signal resource list (sl-PRS-ID-List) indication information element. The sidelink positioning reference signal resource list includes the IDs of one or more positioning reference signal resources, indicating that the first periodic resource can be used for sidelink positioning reference signal transmission. When the configuration information of the first periodic resource includes a sidelink positioning reference signal resource list, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the configuration information of the first periodic resource does not include a sidelink positioning reference signal resource list, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0127] In another possible implementation, the first information is carried in the resource pool configuration information. In this implementation, the first periodic resource may be a periodic resource in the resource pool, that is, a type of resource in the resource pool.

[0128] Optionally, the first information is the first field in the resource pool configuration information. The first field may occupy 1 bit, 2 bits, or other lengths, which are not specifically limited in this application.

[0129] For example, when the value of the first field is the first value, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is the second value, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0130] The following describes some possible implementations of the first value and the second value. This application is still applicable to other implementations, and the following implementations do not limit this application.

[0131] Implementation method 1: When the value of the first field is 0, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is 1, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0132] Implementation method 2: When the value of the first field is 1, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is 0, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0133] Implementation method 3: When the value of the first field is true (true), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is false (false), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0134] Implementation method 4: When the value of the first field is enabled, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is disabled, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0135] The following describes a possible format of resource pool configuration information. This application is still applicable to other formats and is not specifically limited by this application.

[0136] As can be seen from the format of the resource pool configuration information above, the first information is a Sidelink Positioning Reference Signal Indicator (SL-PRS-Indicator) information element, and the value of the Sidelink Positioning Reference Signal Indicator information element can be True or False. When the value of the Sidelink Positioning Reference Signal Indicator information element is True, it indicates that the transmission of the Sidelink Positioning Reference Signal is supported on the first periodic resource; when the value of the Sidelink Positioning Reference Signal Indicator information element is False, it indicates that the transmission of the Sidelink Positioning Reference Signal is not supported on the first periodic resource.

[0137] The following describes another possible format for resource pool configuration information.

[0138] As can be seen from the format of the resource pool configuration information above, the first information is a Sidelink Positioning Reference Signal Indicator (SL-PRS-Indicator) information element, and the value of the Sidelink Positioning Reference Signal Indicator information element can be Enable or Disable. When the value of the Sidelink Positioning Reference Signal Indicator information element is Enable, it indicates that the transmission of the Sidelink Positioning Reference Signal is supported on the first periodic resource; when the value of the Sidelink Positioning Reference Signal Indicator information element is Disable, it indicates that the transmission of the Sidelink Positioning Reference Signal is not supported on the first periodic resource.

[0139] Optionally, the embodiment shown in FIG5 further includes step 502a.

[0140] 502a: The network device sends the second information to the terminal device. Correspondingly, the terminal device receives the second information from the network device.

[0141] The second information indicates whether the first periodic resource supports data transmission.

[0142] In a possible implementation, the first information and the second information are two different pieces of information. Optionally, the first information and the second information are two different fields.

[0143] Optionally, the first information and the second information are carried in the configuration information of the first periodic resource. For example, the first information and the second information are respectively fields in the configuration information of the first periodic resource. Optionally, the first information and the second information are two fields in the configuration information of the first periodic resource. Alternatively, the first information and the second information are carried in the resource pool configuration information. For example, the first information and the second information are respectively fields in the resource pool configuration information. Optionally, the first information and the second information are two fields in the resource pool configuration information.

[0144] The following describes a possible format of the configuration information of the first periodic resource. This application is still applicable to other formats and does not limit them specifically.

[0145] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first information is the sidelink positioning reference signal indication (SL-PRS-Indicator) information element, and the value of the sidelink positioning reference signal indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink positioning reference signal indication information element is enabled (enabled), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is disabled (disabled), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. The second information is the sidelink data indication (sl-Data-Indicator) information element, and the value of the sidelink data indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink data indication information element is enabled (enabled), it indicates that the transmission of data is supported on the first periodic resource; when the value of the sidelink data indication information element is disabled (disabled), it indicates that the transmission of data is not supported on the first periodic resource.

[0146] The following is another possible format of resource pool configuration information. This application is still applicable to other formats and is not limited to them.

[0147] As can be seen from the format of the resource pool configuration information above, the first information is the sidelink positioning reference signal indication (SL-PRS-Indicator) information element, and the value of the sidelink positioning reference signal indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink positioning reference signal indication information element is enabled (enabled), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is disabled (disabled), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. The second information is the sidelink data indication (sl-Data-Indicator) information element, and the value of the sidelink data indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink data indication information element is enabled (enabled), it indicates that the transmission of data is supported on the first periodic resource; when the value of the sidelink data indication information element is disabled (disabled), it indicates that the transmission of data is not supported on the first periodic resource.

[0148] In another possible implementation, the first information and the second information are the same information, and two different values ​​of the information indicate different meanings. Optionally, the first information and the second information are the same field.

[0149] For example, when the value of this information is a first value, it indicates that the first periodic resource supports the transmission of a sidelink positioning reference signal. When the value of this information is a second value, it indicates that the first periodic resource supports the transmission of data. In other words, the first periodic resource supports either the transmission of a sidelink positioning reference signal or the transmission of data. In other words, the first periodic resource can only support the transmission of one of the sidelink positioning reference signal and data.

[0150] Optionally, the length of the information is 1 bit, 2 bits, or other lengths, which is not limited in this application. For example, the length of the information is 1 bit, and when the value of the information is 1, it indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal; when the value of the information is 0, it indicates that the first periodic resource supports the transmission of data. Alternatively, the length of the information is 1 bit, and when the value of the information is 0, it indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal; when the value of the information is 1, it indicates that the first periodic resource supports the transmission of data.

[0151] In this implementation, the information is carried in the configuration information of the first periodic resource or the resource pool configuration information.

[0152] The following describes a possible format of the configuration information of the first periodic resource. This application is still applicable to other formats and does not limit them specifically.

[0153] As can be seen from the format of the configuration information of the first periodic resource described above, the information is a sidelink data or positioning reference signal indication (sl-Data and PRS-Indicator) information element, and the value of the sidelink data or positioning reference signal indication information element can be enabled or disabled. For example, when the value of the sidelink data or positioning reference signal indication information element is enabled, it indicates that the first periodic resource supports transmission of the sidelink positioning reference signal; when the value of the sidelink data or positioning reference signal indication information element is disabled, it indicates that the first periodic resource supports transmission of data.

[0154] The following describes another possible format of resource pool configuration information. This application is still applicable to other formats and is not specifically limited in this application.

[0155] As can be seen from the format of the resource pool configuration information described above, this information is a sidelink data or positioning reference signal indication (sl-Data and PRS-Indicator) information element, and the value of the sidelink data or positioning reference signal indication information element can be enabled or disabled. For example, when the value of the sidelink data or positioning reference signal indication information element is enabled, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink data or positioning reference signal indication information element is disabled, it indicates that the transmission of data is supported on the first periodic resource.

[0156] It should be noted that there is no fixed order for executing step 502a and steps 501 to 502. Step 502a may be executed first, followed by steps 501 to 502; or steps 501 to 502 may be executed first, followed by step 502a; or, depending on the circumstances, both steps 502a and 501 to 502 may be executed simultaneously, which is not limited in this application.

[0157] Optionally, the embodiment shown in FIG5 further includes step 502b.

[0158] 502b: The network device sends the third information to the terminal device. Correspondingly, the terminal device receives the third information from the network device.

[0159] The third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data at the same time. It can be understood that the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time slot or the same time domain symbol. Of course, the third information can also be interpreted as: the third information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data in the same time domain resource. The unit of the time domain resource is not limited in this application. For example, the same time domain resource can be the same frame, the same subframe, the same time domain symbol, or the same time slot, etc., which is not specifically limited in this application.

[0160] In a possible implementation, the first information, the second information, and the third information may be three different pieces of information. Alternatively, the first information, the second information, and the third information may be three different fields.

[0161] Optionally, the first information, the second information, and the third information are carried in the configuration information of the first periodic resource. For example, the first information, the second information, and the third information are fields in the configuration information of the first periodic resource. Alternatively, the first information, the second information, and the third information are carried in the resource pool configuration information. For example, the first information, the second information, and the third information are fields in the resource pool configuration information.

[0162] The following describes a possible format of the configuration information of the first periodic resource. This application is still applicable to other formats and does not limit them specifically.

[0163] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first information is the sidelink positioning reference signal indication (SL-PRS-Indicator) information element, and the value of the sidelink positioning reference signal indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink positioning reference signal indication information element is enabled (enabled), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is disabled (disabled), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. The second information is the sidelink data indication (sl-Data-Indicator) information element, and the value of the sidelink data indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink data indication information element is enabled (enabled), it indicates that the transmission of data is supported on the first periodic resource; when the value of the sidelink data indication information element is disabled (disabled), it indicates that the transmission of data is not supported on the first periodic resource. The third information is a sidelink data or positioning (sl-Data and PRS-Indicator) information element. The value of the sidelink data or positioning information element can be enabled or disabled. When the value of the sidelink data or positioning information element is enabled, it indicates that the first periodic resource supports simultaneous transmission of a sidelink positioning reference signal and data. When the value of the sidelink data or positioning information element is disabled, it indicates that the first periodic resource does not support simultaneous transmission of a sidelink positioning reference signal and data.

[0164] The following describes another possible format of resource pool configuration information. This application is still applicable to other formats and is not specifically limited in this application.

[0165] As can be seen from the format of the resource pool configuration information above, the first information is the sidelink positioning reference signal indication (SL-PRS-Indicator) information element, and the value of the sidelink positioning reference signal indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink positioning reference signal indication information element is enabled (enabled), it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource; when the value of the sidelink positioning reference signal indication information element is disabled (disabled), it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource. The second information is the sidelink data indication (sl-Data-Indicator) information element, and the value of the sidelink data indication information element can be enabled (enabled) or disabled (disabled). When the value of the sidelink data indication information element is enabled (enabled), it indicates that the transmission of data is supported on the first periodic resource; when the value of the sidelink data indication information element is disabled (disabled), it indicates that the transmission of data is not supported on the first periodic resource. The third information is a sidelink data or positioning (sl-Data and PRS-Indicator) information element. The value of the sidelink data or positioning information element can be enabled or disabled. When the value of the sidelink data or positioning information element is enabled, it indicates that the simultaneous transmission of the sidelink positioning reference signal and data is supported on the first periodic resource. When the value of the sidelink data or positioning information element is disabled, it indicates that the simultaneous transmission of the sidelink positioning reference signal and data is not supported on the first periodic resource.

[0166] In another possible implementation, the first information, the second information, and the third information are the same information, and the three different values ​​of the information indicate different meanings. For example, when the value of the information is the third value, it indicates that the first periodic resource supports the transmission of a sidelink positioning reference signal; when the value of the information is the fourth value, it indicates that the first periodic resource supports the transmission of data; and when the value of the information is the fifth value, it indicates that the first periodic resource supports the transmission of both a sidelink positioning reference signal and data. In other words, the first periodic resource either supports the transmission of a sidelink positioning reference signal, supports the transmission of data, or supports the simultaneous transmission of a sidelink positioning reference signal and data.

[0167] Optionally, the length of this information can be 2 bits, 3 bits, or other lengths, which are not limited in this application. For example, if the length of this information is 2 bits, when the value of this information is 00, it indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal; when the value of this information is 01, it indicates that the first periodic resource supports the transmission of data; when the value of this information is 10, it indicates that the first periodic resource supports the transmission of both the sidelink positioning reference signal and data.

[0168] In this implementation, the information is carried in the configuration information of the first periodic resource or the resource pool configuration information.

[0169] The following describes a possible format of the configuration information of the first periodic resource. This application is still applicable to other formats and does not limit them specifically.

[0170] As can be seen from the format of the configuration information of the first periodic resource mentioned above, this information is a sidelink positioning reference signal indication (sl-PRS-Indicator) information element. The value of the sidelink positioning reference signal indication information element can be 0, 1, or 2. For example, when the value of the sidelink positioning reference signal indication information element is 0, it indicates that data transmission is supported on the first periodic resource. When the value of the sidelink positioning reference signal indication information element is 1, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource. When the value of the sidelink positioning reference signal indication information element is 2, it indicates that the first periodic resource supports simultaneous transmission of the sidelink positioning reference signal and data.

[0171] The following describes a possible format of resource pool configuration information. This application is still applicable to other formats and is not specifically limited by this application.

[0172] As can be seen from the format of the resource pool configuration information above, this information is a sidelink positioning reference signal indication (sl-PRS-Indicator) information element. The value of the sidelink positioning reference signal indication information element can be 0, 1, or 2. For example, when the value of the sidelink positioning reference signal indication information element is 0, it indicates that data transmission is supported on the first periodic resource. When the value of the sidelink positioning reference signal indication information element is 1, it indicates that the transmission of the sidelink positioning reference signal is supported on the first periodic resource. When the value of the sidelink positioning reference signal indication information element is 2, it indicates that the simultaneous transmission of the sidelink positioning reference signal and data is supported on the first periodic resource.

[0173] It should be noted that there is no fixed order for executing step 502b and steps 501 to 502a. Step 502b may be executed first, followed by steps 501 to 502a; or, steps 501 to 502a may be executed first, followed by step 502b; or, depending on the circumstances, steps 502b and 501 to 502a may be executed simultaneously. This application does not impose any specific restrictions.

[0174] 503. The terminal device determines whether the first periodic resource supports the transmission of the sidelink positioning reference signal based on the first information.

[0175] In one possible implementation, the terminal device further receives second information, and the terminal device determines whether the first periodic resource supports data transmission based on the second information. Optionally, the terminal device further receives third information, and the terminal device determines whether the first periodic resource supports both sidelink positioning reference signal and data transmission based on the third information.

[0176] In another possible implementation, the first information and the second information are the same information, and the terminal device determines whether the first periodic resource supports transmission of a sidelink positioning reference signal or data based on the value of the information. For example, when the value of the information is 1, the terminal device determines that the first periodic resource supports transmission of a sidelink positioning reference signal; when the value of the information is 0, the terminal device determines that the first periodic resource supports transmission of data.

[0177] Optionally, the first information, the second information, and the third information are the same information. The terminal device determines, based on the value of the information, whether the first periodic resource supports the transmission of the sidelink positioning reference signal, the transmission of data, or the transmission of both the sidelink positioning reference signal and data. For example, when the value of the information is 00, the terminal device determines that the first periodic resource supports the transmission of the sidelink positioning reference signal; when the value of the information is 01, the terminal device determines that the first periodic resource supports the transmission of data; when the value of the information is 10, the terminal device determines that the first periodic resource supports the transmission of both the sidelink positioning reference signal and data.

[0178] In an embodiment of the present application, a terminal device receives first information from a network device, where the first information indicates whether a first periodic resource supports the transmission of a sidelink positioning reference signal. The first periodic resource is a sidelink resource configured by the network device for the terminal device. The terminal device determines whether the first periodic resource supports the transmission of a sidelink positioning reference signal based on the first information. As can be seen, the terminal device receives first information from the network device, where the first information indicates whether the first periodic resource supports the transmission of a sidelink positioning reference signal. This enables the terminal device to determine whether the first periodic resource can be used for the transmission of a sidelink positioning reference signal.

For ease of understanding and illustration, Figure 8 uses a mobile phone as an example of a terminal device. As shown in Figure 8, the terminal device includes a processor, memory, radio frequency circuitry, an antenna, and input / output devices.

[0220] Input and output devices, such as touch screens, display screens, keyboards, etc., are mainly used to receive data input by users and output data to users. It should be noted that some types of terminal devices may not have input and output devices.

[0221] When data needs to be sent, the processor performs baseband processing on the data to be transmitted and outputs the baseband signal to the RF circuit. The RF circuit then performs RF processing on the baseband signal and transmits it via the antenna in the form of electromagnetic waves. When data is sent to a terminal device, the RF circuit receives the RF signal via the antenna, converts it into a baseband signal, and outputs the baseband signal to the processor, which converts the baseband signal into data and processes it.

[0222] For ease of explanation, Figure 8 shows only one memory and processor. In actual terminal device products, one or more processors and one or more memories may exist. Memory may also be referred to as a storage medium or storage device. The memory may be provided independently of the processor or integrated with the processor, and this embodiment of the application does not impose any restrictions on this.

The transceiver module in section 930, which can also be referred to as a transceiver or transceiver, includes an antenna 933 and a RF circuit (not shown in the figure), where the RF circuit is primarily used for RF processing. Optionally, the device used to implement the receiving function in section 930 can be considered a receiver, and the device used to implement the transmitting function can be considered a transmitter. That is, section 930 includes a receiver 932 and a transmitter 931.

If multiple boards are present, the boards may be interconnected to enhance processing capabilities. As an optional implementation, multiple boards may share one or more processors, multiple boards may share one or more memories, or multiple boards may simultaneously share one or more processors.
