In addition, in the embodiments of the present application, words such as "optionally" or "exemplarily" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "optional" or "exemplary" in the embodiments of the present application shall not be interpreted as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "optionally" or "exemplarily" is intended to present related concepts in a concrete manner.

In order to facilitate the understanding of the solutions provided by the embodiments of the present application, the relevant concepts involved in the embodiments of the present application are described here, as follows:

In a Sidelink communication system, when there is business to be transmitted between user equipments (User Equipment, UE), the business between UEs does not pass through the network side, that is, it does not pass through the cellular link between the UE and the base station. Instead, the data is directly transmitted from the source UE to the target UE through Sidelink. This mode of direct communication between UEs has characteristics different from the communication mode of traditional cellular systems. Applications of Sidelink communication include Device-to-Device (D2D) communication and Vehicle to Everything (V2X) communication. Among them, the Internet of Vehicles (V2X) communication includes Vehicle to Vehicle (V2V), Vehicle to Pedestrian (V2P), Vehicle to Infrastructure (V2I).

In this embodiment of the application, the user equipment may be a cellular phone, a cordless phone, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with a wireless communication function, a computing device or other processing devices connected to a wireless modem, or a vehicle-mounted device , wearable devices, or the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) network or terminal equipment in the future 5G network. The base station can be an evolved base station (Evolutional Node B, eNB or eNodeB) in Long Term Evolution (LTE), Long Term Evolution advanced (LTE-A), or a new radio (New Radio, NR) The 5G base station equipment represented by the air interface, or the base station in the future communication system, etc. The base station may also include various network side devices such as various macro base stations, micro base stations, home base stations, remote wireless, routers, or primary cells (primary cells) and cooperative cells (secondary cells), which is not limited in this embodiment .

In the Multi-RTT positioning method, generally, the serving base stations corresponding to the target node and the anchor node are respectively responsible for allocation of positioning reference signals to the corresponding nodes. This method is shown in Figure 1, assuming that UE1 is the target node, UE2 is any one of the anchor nodes, UE1 sends a positioning reference signal (Positioning reference signal, PRS) 1 resource request to base station 1, and obtains PRS1 resource allocation, UE1 Send a PRS2 resource request to UE2 on the allocated PRS1 resource. Correspondingly, UE2 sends a PRS2 resource request to base station 2 and obtains the PRS2 resource allocation, and then sends information to UE1 on the allocated PRS2 resource to interact with UE1. Since both the target node and the anchor node need to request positioning reference signal resources from their respective serving base stations, this will lead to a large delay in the allocation of positioning reference signal resources, thereby affecting the positioning accuracy of the target node.

Based on the above problems, an embodiment of the present application provides a flow chart of a method for positioning reference signal resource indication, as shown in FIG. 2 , the method may include:

When the first communication node is a base station, the second communication node may be a target node; when the first communication node is a target node, the second communication node may be an anchor node. That is, the communication between the first communication node and the second communication node in the embodiment of the present application may be communication between the base station and the target node, or communication between the target node and the anchor node.

The first information sent by the first communication node may include a communication node number, and the second information sent by the first communication node may be used to indicate a positioning reference signal resource number.

In the above scheme, since there is a mapping relationship between the communication node number contained in the first information communicated between nodes and the positioning reference signal resource number indicated by the second information, it can be avoided that the positioning reference signal resource used by the node is different from that used by other nodes. resource conflict.

In an example, when the first communication node is a base station and the second communication node is a target node, the communication node number contained in the first information may include the number of the second communication node and at least one third communication node The serial number of the node, wherein, the third communication node is the same type of communication node as the second communication node. That is, when the second communication node is a target UE, the third communication node may also be a node of UE type, for example, the third communication node may be an anchor UE. That is, the base station sends the first information about the number of the target UE and the number of at least one anchor UE to the target UE. Correspondingly, the positioning reference signal resource number indicated by the second information may include multiple positioning reference signal resource numbers.

In another example, when the first communication node is the target node and the second communication node is the anchor node, the communication node number contained in the first information may also include the number of at least one second communication node, Correspondingly, the number of the second communication node may also be at least one, that is, the target UE sends the first information about the serial number of at least one anchor UE to at least one anchor UE. Correspondingly, the positioning reference signal resource number sent by the first communication node includes at least one positioning reference signal resource number, which may also be understood as the number of the positioning reference signal resource used by at least one anchor UE.

In any of the above cases, since there is a mapping relationship between the communication node number and the positioning reference signal resource number, based on the mapping relationship, the positioning reference signal used by the target UE and at least one anchor UE, which are nodes with different numbers, can be determined. The ID of the resource. In this way, both the target UE and the anchor UE need to request positioning reference signal resources from their respective serving base stations, thereby reducing communication delay and improving positioning accuracy of the target node.

In an example, the above communication node numbers may be used to distinguish different communication nodes, and the communication nodes may be UEs, for example, a target UE and at least one anchor UE, or at least one anchor UE. The above communication node number may include but not limited to at least one of the following:

In an example, each target value above may be determined by a calculation formula, and the calculation formula includes the first positioning reference signal resource number; or, each target value is determined by a calculation formula, and the calculation formula includes the first positioning reference signal A signal resource number and a second positioning reference signal resource number.

For example, if a target value is used to indicate a positioning reference signal resource number x, the target value is calculated by a formula, and the calculation formula of the target value includes the positioning reference signal resource number x. Or, if a target value is used to indicate two positioning reference signal resource numbers x and y, the target value is calculated by a formula, and the calculation formula of the target value includes the positioning reference signal resource number x and the positioning reference signal resource label y.

In an example, the above-mentioned mapping relationship between the number of the communication node and the number of the positioning reference signal resource may include: the number of the i-th communication node is in a mapping relationship with the number of the i-th positioning reference signal resource, and i is a non-negative integer .

In an example, when the first communication node is the target node, the first communication node is further configured to report the time-frequency resource corresponding to the at least one positioning reference signal resource to the base station. That is, the first communication node acts as the target node, which indicates the positioning reference signal resource to at least one second communication node (ie, the anchor node), and reports the indication result of the positioning reference signal resource of the at least one second communication node to the base station.

In an example, the first information and the second information sent by the first communication node may be carried in side link control information (Sidelink Control Information, SCI). Or, the first information may be carried in radio resource control (Radio Resource Control, RRC) signaling, and the second information may be carried in SCI.

Fig. 3 provides a flow chart of a method for positioning reference signal resource indication according to an embodiment of the present application. The method may be applied to a second communication node. As shown in Fig. 3 , the method may include:

S301. The second communication node receives first information and second information sent by the first communication node.

In this embodiment of the present application, the second communication node may be a target node (ie, target UE) or an anchor node (ie, anchor UE), and the first communication node may be a base station or a target node. That is, in S301, the second communication node receives the information sent by the first communication node, and may receive the information sent by the base station for the target node, or may also receive the information sent by the target node for the anchor node. The first information received by the second communication node may include a communication node number, and the communication node number may be used to distinguish different communication nodes. The second information may be used to indicate the positioning reference signal resource number. In the embodiment of the present application, there is a mapping relationship between the communication node number and the positioning reference signal resource number.

S302. The second communication node determines a positioning reference signal resource number corresponding to the number of the second communication node according to the mapping relationship.

In this embodiment of the present application, since there is a mapping relationship between the communication node number contained in the first information and the positioning reference signal resource number indicated by the second information when the first communication node communicates with the second communication node, the second communication node After receiving the first information and the second information, it is judged that the communication node number contained in the first information contains the second communication node number, then it can be determined that the second communication node can use The number of the positioning reference signal resource, so that the conflict between the positioning reference signal resource used and the resources used by other nodes can be effectively avoided.

In an example, when the above-mentioned second communication node is a target node and the first communication node is a base station, the communication node number contained in the first information may include the number of the second communication node and at least one third communication node , wherein the third communication node and the second communication node are communication nodes of the same type. That is, the second communication node is a target UE, and the third communication node may also be a node of UE type, for example, the third communication node may be an anchor UE. Correspondingly, the positioning reference signal resource number indicated by the second information may also include multiple positioning reference signal resource numbers.

After the second communication node determines the positioning reference signal resource number corresponding to the number of the second communication node according to the mapping relationship between the communication node number in the first information and the positioning reference signal resource number indicated in the second information, it can The positioning reference signal (for example, PRS1) is sent to the third communication node on the positioning reference signal resource corresponding to the reference signal resource number. In addition, the second communication node sends the third information and the fourth information to the third communication node, and the number of the third communication nodes may be one or more. As shown in FIG. 4, the third communication node may include UE2 and UE3. a communication node.

The fourth information is used to indicate at least one positioning reference signal resource number, and there is a mapping relationship between the number of the at least one third communication node and the at least one positioning reference signal resource number indicated by the fourth information.

Correspondingly, after receiving the third information and the fourth information sent by the second communication node, the third communication node may locate the reference signal resource according to at least one serial number of the third communication node in the third information and at least one of the fourth information. The mapping relationship between numbers determines the number of positioning reference signal resources mapped to or corresponding to the number of the third communication node, and sends the positioning reference signal to the second communication node based on the resource corresponding to the determined positioning reference signal resource number. For example, assume that the positioning reference signal sent by the third communication node UE2 to the second communication node is PRS2, and the positioning reference signal sent by the third communication node UE3 to the second communication node is PRS3. The above-mentioned entire communication process can be shown in FIG. 4, wherein, base station 1 is a first communication node, and is used to provide services to a second communication node (UE1, that is, a target node), and base station 2 is used to provide services to a third communication node (UE2 and UE3) provides services.

In the above process, since the second communication node (target node) and at least one third communication node (anchor node) both determine the resources for sending positioning reference signals, and send positioning reference signals to each other on the resources determined respectively, satisfying If the condition of Multi-RTT positioning is satisfied, then the second communication node can determine the positioning of the second communication node through the Multi-RTT positioning method.

After receiving the first information and the second information, the second communication node may determine the number of the second communication node according to the mapping rule between the communication node number in the first information and the positioning reference signal resource number indicated by the second information The corresponding positioning reference signal resource number. Based on the above process, since the second communication node has determined its own positioning reference signal resource number, the second communication node may send a positioning reference signal to the first communication node according to the positioning reference signal resource corresponding to the positioning reference signal resource number. Similarly, since both the first communication node (target node) and the second communication node (anchor node) have determined resources for sending positioning reference signals, and mutually send positioning reference signals on the resources determined respectively, the Multi-RTT location conditions, then the first communication node can determine the location of the first communication node through the Multi-RTT positioning method.

Correspondingly, the embodiment of the present application further provides an implementation manner including: the first communication node reports the time-frequency resource corresponding to the at least one positioning reference signal resource number to the base station. That is, the first communication node, as the target node, sends the indicated positioning reference signal resource (first information and second information) to the anchor node, and reports the resource indication result to the base station.

In an example, the above-mentioned mapping relationship between the number of the communication node and the number of the positioning reference signal resource may include: the number of the i-th communication node is in a mapping relationship with the number of the i-th positioning reference signal resource, and i is a non-negative integer .

In an example, the above fourth information may also include at least one target value, where each target value indicates the first positioning reference signal resource number; or, each target value indicates the first positioning reference signal resource number and the second Positioning reference signal resource number.

The content contained in the third information is a subset of the content contained in the first information, and the content contained in the fourth information is a subset of the content contained in the second information. That is, both the first information and the second information carry relevant information of the second communication node and relevant information of at least one third communication node, and the third information and the fourth information sent by the second communication node to the third communication node both carry The relevant information of the third communication node does not include the relevant information of the second communication node.

Or, if a target value is used to indicate two positioning reference signal resource numbers x and y, the target value is calculated by a formula, and the calculation formula of the target value includes the positioning reference signal resource number x and the positioning reference signal resource label y.

That is, when the second communication node is the target node, the positioning reference signal resource number indicated by the target value can be determined according to the target value in the second information. Alternatively, the third communication node determines the positioning reference signal resource number indicated by the target value according to the target value in the fourth information.
