Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an indication method and related devices. Background Art

[0002] In the sidelink communication system, the sidelink resource scheduling supports three modes, namely dynamic scheduling, semi-static scheduling and periodic scheduling. After the positioning function is introduced in the sidelink communication resource pool, the user can send data and sidelink positioning reference signals simultaneously in one time slot. For the sidelink resource, how the user determines whether to transmit the sidelink positioning reference signal on the sidelink resource is a question worth considering. Summary of the invention

[0003] The present application provides an indication method and a related device, which is used for a terminal device to receive first information from a network device, wherein the first information indicates whether a first periodic resource supports the transmission of a sidelink positioning reference signal, thereby enabling the terminal device to determine whether the first periodic resource can be used for the transmission of a sidelink positioning reference signal.

[0004] 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, which is not specifically limited in the present application. 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, which is not specifically limited in the present application. In the first aspect and its possible implementation methods, the method is described as being executed by a terminal device. The method comprises:

[0005] The terminal device receives the first information from the network device, the first information indicating whether the first periodic resource supports the transmission of the sidelink positioning reference signal, and the first periodic resource is the sidelink resource configured by the network device for the terminal device; the terminal device determines whether the first periodic resource supports the transmission of the sidelink positioning reference signal based on the first information. It can be seen that the terminal device receives the first information from the network device, and the first information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal. Thereby, the terminal device determines whether the first periodic resource can be used for the transmission of the sidelink positioning reference signal.

[0006] 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 the transmission of data. In this implementation, the terminal device may also receive the second information to determine whether the first periodic resource supports the transmission of data. 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 to say, the first periodic resource either supports the transmission of a sidelink positioning reference signal, or supports the transmission of data.

[0007] 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 may indicate that the first periodic resource supports the transmission of the sidelink positioning reference signal, or supports the transmission of data by the first periodic resource, 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.

[0008] The second aspect of the present application provides an indication method, which is executed 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, which is not specifically limited in the present application. 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, which is not specifically limited in the present application. In the second aspect and its possible implementation methods, the method is described as being executed by a network device. The method comprises:

[0009] The network device determines the first information, the first information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal, and the first periodic resource is the sidelink resource configured by the network device for the terminal device; the network device sends the first information to the terminal device. It can be seen that the network device sends the first information to the terminal device, and the first information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal. Thereby, the terminal device determines whether the first periodic resource can be used for the transmission of the sidelink positioning reference signal.

[0010] 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 the transmission of data. In this implementation, the network device also sends the second information. This facilitates the terminal device to determine whether the first periodic resource supports the transmission of data. 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 the transmission of data. That is to say, the first periodic resource either supports the transmission of a sidelink positioning reference signal, or supports the transmission of data.

[0011] Based on the second aspect, in a possible implementation, the method further includes: the network device sends a 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 may indicate that the first periodic resource supports the transmission of the sidelink positioning reference signal, or supports the transmission of data by the first periodic resource, 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.

[0012] 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.

[0013] Based on the first aspect or the second aspect, in a possible implementation manner, the first information is a first field in configuration information of a first periodic resource, or a first field in resource pool configuration information.

[0014] Based on the first aspect or the second aspect, in a possible implementation, when the value of the first field is a first value, it indicates that the first periodic resource supports the 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 the 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 the transmission of a sidelink positioning reference signal.

[0015] Based on the first aspect or the second aspect, in a 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 the transmission of a sidelink positioning reference signal, and 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 whether the first periodic resource supports the transmission of a sidelink positioning reference signal through the first information.

[0025] Based on the fourth aspect, in a possible implementation manner, the transceiver module is further used to: send second information to the first communication device, where the second information indicates whether the first periodic resource supports data transmission.

[0026] 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.

[0027] Based on the third aspect or the fourth aspect, in a possible implementation manner, the first information is carried in configuration information of the first periodic resource, or the first information is carried in resource pool configuration information.

[0028] Based on the third aspect or the fourth aspect, in a possible implementation manner, the first information is a first field in configuration information of a first periodic resource, or a first field in resource pool configuration information.

[0029] Based on the third aspect or the fourth aspect, in a possible implementation method, when the value of the first field is a first value, it indicates that the transmission of a sidelink positioning reference signal is supported on the first periodic resource; when the value of the first field is a second value, it indicates that the transmission of a sidelink positioning reference signal is not supported on the first periodic resource.

This application is not limited.

[0071] 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.

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 (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 (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

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

[0085] CU-CP can interact with 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 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. CU-UP can interact with 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 device.

[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, by delay, the functions that need to meet the smaller delay requirements for processing time are set in the DU, and the functions that do not need to meet the delay requirements are set in the CU.

[0087] DU and RU can cooperate to jointly implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in a variety of ways according to the design. For example, DU is configured to implement baseband functions, and RU is configured to implement mid-RF functions. For another example, DU is configured to implement high-level functions in the PHY layer, and RU is configured to implement low-level functions in the PHY layer or to implement the low-level functions and RF functions. The high-level 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-level 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 (e.g., a chip), a module, or a unit in the device or apparatus shown above, and the specific application is not limited. 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 the present application, some technical terms involved in the present 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 understand the meaning of resource pool, Figure 4 The resource pool in the sidelink system is introduced as an example. Figure 4 , a part of a carrier bandwidth used for the sidelink spectrum can be called the sidelink bandwidth part SL BWP (sidelink bandwidth part), and multiple resource pools can be defined in the SL BWP. Figure 4 Five resource pools are shown (resource pool #1, resource pool #2, resource pool #3, resource pool #4, and resource pool #5).

[0092] Independent channels such as PSCCH and PSSCH can be configured in each resource pool, and independent perception and resource allocation can be performed. The resource pool can be configured with multiple continuous RBs in the frequency domain, and a certain number of continuous RBs can form a subchannel. Resource allocation and data transmission can be performed in units of subchannels. That is, a terminal device can occupy one or more subchannels for data transmission. In other words, the minimum unit granularity for a terminal device to send or receive sidelink data can be called a subchannel. The number of RBs in a subchannel can be 10, 12, 15, 20, 25, 50, 75 or 100.

[0093] Optionally, in the 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. A positioning function may be further introduced into the communication resource pool, so the communication resource pool that introduces the positioning function may be referred to as a shared resource pool. In other words, a resource pool that supports both the communication function and the positioning function 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. Semi-static resources, semi-periodic resources and semi-persistent resources have the same meaning and can be replaced with each other.

[0097] Periodic resources are also called configured grant type 1 (CG Type 1) resources or sidelink configured grant type 2 (SL CG Type 1) resources. The base station configures them through high-level signaling. For example, the base station configures parameters such as resource period through RRC signaling. After the configuration is completed, the terminal device sends 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 the resource pool. Time-frequency resources include time domain resources and frequency domain resources. Among them, time domain resources can be expressed as symbols, slots, sub-slots, mini-slots, partial slots, sub-frames, radio frames, or sensing slots. Frequency domain resources can be expressed as resource elements (RE), resource blocks (RB), sub-channels, resource pools, bandwidths, bandwidth parts (BWP), carriers, channels, or interlaces.

[0099] After the positioning function is introduced into the communication resource pool, the user can send data and sidelink positioning reference signals simultaneously in one time slot. In the sidelink communication system, for periodic resources, how the user determines whether the periodic sidelink positioning reference signal can be transmitted in the periodic resource is a question worth considering. The present application provides an indication method and related devices 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 introduction of the embodiments below.

[0100] The technical solution of the present application is introduced below in conjunction with embodiments.

[0101] Figure 5 This is a schematic diagram of an embodiment of the indication method of the present application. Figure 5 , methods include:

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

[0103] The first information indicates whether the first periodic resource supports the transmission of the sidelink positioning reference signal. For example, the first information is the 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 a configuration parameter related to the sidelink reference signal resource. For example, one or more of a comb number, an offset number, a number of symbols, a starting symbol number, etc. The configuration of the first periodic resource includes the above one or more 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 a 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 CGType1 resource.

[0110] For example, for a terminal device, the high-level 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 preferentially for data transmission. 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 a 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 a 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 a second value, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0113] Some possible implementations of the first value and the second value are introduced below. 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 also includes at least one of the following: a side link configuration grant (SL CG) index, a time domain period of SL transmission, a first indication information, an offset number used when deriving a hybrid automatic repeat request (HARQ) process number, a second indication information, a third indication information, a fourth indication information, a fifth indication information, a sixth indication information, or a 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 (transportblock, TB) is completed through a maximum of N transmissions, and 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 time slot of the three time slots is a time slot reserved by 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 time slots of the three time slots are two time slots reserved corresponding to the resource reservation index of the terminal device from 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 feedback confirmation message (acknowledgement, ACK) or negative confirmation message (non-acknowledgement, NACK) information through the physical uplink control channel (physical uplink control channel, PUCCH) resources.

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

[0121]

[0122] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first information is a 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 or disabled. When the value of the sidelink 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 positioning reference signal indication information element is disabled, 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 or false. When the value of the sidelink positioning reference signal indication 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 indication information element is 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 the SL Type1 CG resource.

[0123] 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 and maximum periods 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, and N is usually 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 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 of the terminal device in each cycle of the current CG, and the last two time slots of the three time slots are two time slots reserved 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 of the terminal device 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 indicates that the terminal device feeds back ACK or NACK through the PUCCH resource.

[0124] For periodic sidelink positioning reference signal transmission, since resources within a time slot cannot be multiplexed between multiple users. Therefore, the network device can send a first message to the terminal device, and the first information indicates that the first periodic resource can be used for sidelink positioning reference signal transmission, without indicating the time domain symbol, comb score and frequency domain offset occupied by the sidelink positioning reference signal, thereby saving signaling overhead. The specific sidelink positioning reference signal parameters can be indicated in the sidelink positioning reference signal configuration information of the resource pool.

[0125] It should be noted that, in the format of the configuration information of the above-mentioned first periodic resource, the sidelink positioning reference signal indication element may also be other names, which is not specifically limited in this application.

[0126] Another possible format of the configuration information of the first periodic resource is introduced below.

[0127]

[0128] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the first information is a sidelink positioning reference signal resource list (sl-PRS-ID-List) indication 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 the 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 the 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.

[0129] In another possible implementation, the first information is carried in 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.

[0130] 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.

[0131] For example, when the value of the first field is a 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 a second value, it indicates that the transmission of the sidelink positioning reference signal is not supported on the first periodic resource.

[0132] Some possible implementations of the first value and the second value are introduced below. This application is still applicable to other implementations, and the following implementations do not limit this application.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] The following describes a possible format of resource pool configuration information. This application is still applicable to other formats, and this application does not limit them specifically.

[0138]

[0139] As can be seen from the format of the resource pool configuration information above, the first information is a sidelink positioning reference signal indication (SL-PRS-Indicator) information element, and 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.

[0140] Another possible format of resource pool configuration information is described below.

[0141]

[0142]

[0143] 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 (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.

[0144] Optional, Figure 5 The illustrated embodiment also includes step 502a.

[0145] 502a, the network device sends the second information to the terminal device. Correspondingly, the terminal device receives the second information from the network device.

[0146] The second information indicates whether the first periodic resource supports data transmission.

[0147] 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.

[0148] 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.

[0149] A possible format of the configuration information of the first periodic resource is introduced below. This application is still applicable to other formats, and this application does not make any specific limitations.

[0150]

[0151] 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 or disabled. When the value of the sidelink 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 positioning reference signal indication information element is 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 or disabled. When the value of the sidelink data indication information element is 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, it indicates that the transmission of data is not supported on the first periodic resource.

[0152] The following is another possible format of the resource pool configuration information. This application is still applicable to other formats, and this application does not limit them specifically.

[0153]

[0154] 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 or disabled. When the value of the sidelink 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 positioning reference signal indication information element is 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 or disabled. When the value of the sidelink data indication information element is 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, it indicates that the transmission of data is not supported on the first periodic resource.

[0155] 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.

[0156] For example, when the value of the information is a first value, it indicates that the first periodic resource supports the transmission of a sidelink positioning reference signal, and when the value of the information is a second value, it indicates that the first periodic resource supports 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. That is, the first periodic resource can only support the transmission of one of the sidelink positioning reference signal and data.

[0157] 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, and 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, and when the value of the information is 1, it indicates that the first periodic resource supports the transmission of data.

[0158] In this implementation, the information is carried in the configuration information of the first periodic resource or the resource pool configuration information.

[0159] A possible format of the configuration information of the first periodic resource is introduced below. This application is still applicable to other formats, and this application does not make any specific limitations.

[0160]

[0161]

[0162] As can be seen from the format of the configuration information of the first periodic resource mentioned 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 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.

[0163] Another possible format of resource pool configuration information is introduced below. This application is still applicable to other formats, and this application does not limit them specifically.

[0164]

[0165] As can be seen from the format of the resource pool configuration information 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 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.

[0166] It should be noted that there is no fixed execution order between step 502a and steps 501 to 502. Step 502a may be executed first, and then steps 501 to 502; or, steps 501 to 502 may be executed first, and then step 502a; or, step 502a and steps 501 to 502 may be executed simultaneously according to the circumstances, and the present application does not make any specific limitation.

[0167] Optional, Figure 5 The illustrated embodiment also includes step 502b.

[0168] 502b, the network device sends the third information to the terminal device. Correspondingly, the terminal device receives the third information from the network device.

[0169] 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, and 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.

[0170] In a possible implementation, the first information, the second information and the third information may be three different pieces of information. Optionally, the first information, the second information and the third information may be three different fields.

[0171] 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.

[0172] A possible format of the configuration information of the first periodic resource is introduced below. This application is still applicable to other formats, and this application does not make any specific limitations.

[0173]

[0174] 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 or disabled. When the value of the sidelink 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 positioning reference signal indication information element is 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 or disabled. When the value of the sidelink data indication information element is 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, 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, and 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.

[0175] Another possible format of resource pool configuration information is introduced below. This application is still applicable to other formats, and this application does not limit them specifically.

[0176]

[0177] 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 or disabled. When the value of the sidelink 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 positioning reference signal indication information element is 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 or disabled. When the value of the sidelink data indication information element is 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, 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, and 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.

[0178] 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 the 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; when the value of the information is the fifth value, it indicates that the first periodic resource supports the transmission of both the sidelink positioning reference signal and data. That is, 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 signal and data.

[0179] Optionally, the length of the information can be 2 bits, 3 bits, or other lengths, which are not limited in this application. For example, the length of the information is 2 bits, and when the value of the information is 00, it indicates that the first periodic resource supports the transmission of the sidelink positioning reference signal; when the value of the information is 01, it indicates that the first periodic resource supports the transmission of data; when the value of the information is 10, it indicates that the first periodic resource supports the transmission of both the sidelink positioning reference signal and data.

[0180] In this implementation, the information is carried in the configuration information of the first periodic resource or the resource pool configuration information.

[0181] A possible format of the configuration information of the first periodic resource is introduced below. This application is still applicable to other formats, and this application does not make any specific limitations.

[0182]

[0183] As can be seen from the format of the configuration information of the first periodic resource mentioned above, the 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 the transmission of data 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.

[0184] The following describes a possible format of resource pool configuration information. This application is still applicable to other formats, and this application does not limit them specifically.

[0185]

[0186]

[0187] As can be seen from the format of the resource pool configuration information above, the 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 the transmission of data 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.

[0188] It should be noted that there is no fixed execution order between step 502b and steps 501 to 502a. Step 502b may be executed first, and then steps 501 to 502a; or, steps 501 to 502a may be executed first, and then step 502b; or, depending on the situation, step 502b and steps 501 to 502a may be executed simultaneously, which is not limited in this application.

[0189] 503. The terminal device determines whether the first periodic resource supports the transmission of the sidelink positioning reference signal based on the first information.

[0190] In a possible implementation, the terminal device further receives second information, and the terminal device determines whether the first periodic resource supports data transmission according to the second information. Optionally, the terminal device further receives third information, and the terminal device determines whether the first periodic resource supports the transmission of the sidelink positioning reference signal and data at the same time according to the third information.

[0191] 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 the transmission of the sidelink positioning reference signal or the transmission of data according to 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 the transmission of the sidelink positioning reference signal, and when the value of the information is 0, the terminal device determines that the first periodic resource supports the transmission of data.

[0192] Optionally, the first information, the second information and the third information are the same information. The terminal device determines 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 based on the value of the information. 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.

[0193] In an embodiment of the present application, a terminal device receives first information from a network device, and 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. It can be seen that the terminal device receives first information from a network device, and the first information indicates whether the first periodic resource supports the transmission of a sidelink positioning reference signal. Thereby, the terminal device determines whether the first periodic resource can be used for the transmission of a sidelink positioning reference signal.
