Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for measuring relative position. Background Technology

[0002] Ranging-based services refer to services that utilize the relative distance and / or relative angle between two terminals to provide services. The relative angle typically refers to the angle of arrival (AOA) or the angle of departure (AOD). AOA represents the angle between the received signal and the receiver antenna, while AOD represents the angle between the transmitted signal and the transmit antenna. The relative position between two terminals can be determined by combining the relative distance and the relative angle; measuring the relative distance and / or measuring the relative angle can be referred to as measuring the relative position.

[0003] In practical applications, a terminal may be performing multiple relative position measurement processes. If the terminal receives a new relative position measurement request, it needs to determine whether to accept the new relative position measurement request. Summary of the Invention

[0086] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0087] In practical applications, a terminal may be performing multiple relative position measurement processes. If a new relative position measurement request is received, the terminal needs to determine whether to start a new relative position measurement process or continue the currently executing relative position measurement process.

[0088] To address this issue, embodiments of this disclosure provide a method and apparatus for measuring relative positions.

[0089] Figure 1 This is a flowchart illustrating a method for measuring relative position according to an embodiment of the present disclosure. The method can be executed by a first terminal, which can be a mobile phone, PDA, wearable device, smart home appliance, or other device, to determine whether to receive the relative position measurement request based on the first priority of the relative position measurement request sent by the second terminal.

[0090] like Figure 1 As shown, the method for measuring relative position includes the following steps:

[0091] Step 101: In response to the priority information in the measurement relative position request sent by the second terminal, determine the first priority of the measurement relative position request.

[0092] In this embodiment, if the second terminal needs to obtain a distance-based service, it can send a relative position measurement request to the first terminal, and the first terminal receives the relative position measurement request sent by the second terminal. The relative position measurement request can be a relative distance measurement request and / or a relative angle measurement request, and may include the service type to which the distance-based service the second terminal needs to obtain belongs.

[0093] The second terminal can be a mobile phone, a PDA, a wearable device, a smart home appliance, or other similar devices. The second terminal can be the same type of device as the first terminal, such as a mobile phone, or it can be a different type of device, such as a mobile phone as the first terminal and a smart air conditioner as the second terminal.

[0094] In this embodiment, the first terminal determines the first priority of the measurement relative location request in response to the priority information obtained from the measurement relative location request sent by the second terminal. For example, the first priority of the measurement relative location request can be determined according to the priority of the service type corresponding to the measurement relative location request sent by the second terminal, wherein the higher the priority of the service type, the higher the first priority.

[0095] Step 102: Determine whether to accept the request to measure relative position based on the first priority.

[0096] In this embodiment, after determining the first priority of the measurement relative position request from the second terminal, it can be determined whether to receive the measurement relative position request based on the first priority. For example, in response to a second priority that is higher than any currently executing measurement relative position process, the first terminal receives the measurement relative position request from the second terminal.

[0097] The method for measuring relative position according to embodiments of this disclosure is applied to a first terminal. It determines a first priority of the relative position measurement request in response to priority information obtained from a relative position measurement request sent by a second terminal, and determines whether to receive the request based on the first priority. Thus, the terminal determines whether to receive a new relative position measurement request based on its priority.

[0098] In one embodiment of this disclosure, when the first terminal determines whether to receive the measurement relative position request from the second terminal, it can also determine whether to receive the measurement relative position request from the second terminal based on the number of measurement relative position processes that the first terminal supports and can be performed simultaneously, the number of measurement relative position processes that are being executed, etc.

[0099] The number of relative position measurement processes that the first terminal can support simultaneously can be set according to the processing capability of the first terminal.

[0100] In this embodiment, the first terminal may receive a measurement relative position request from the second terminal in response to the fact that the number of measurement relative position processes that the first terminal supports executing simultaneously is greater than the number of measurement relative position processes that are currently being executed.

[0101] Optionally, in response to the first terminal supporting the simultaneous execution of a relative position measurement process equal to the number of relative position measurement processes currently being executed, indicating that the number of relative position measurement processes that the first terminal can perform simultaneously has reached saturation, the first terminal may reject the second terminal's relative position measurement request.

[0102] In this embodiment of the present disclosure, the first terminal can determine whether to receive the measurement relative position request from the second terminal based on the number of measurement relative position processes that can be performed simultaneously supported by the first terminal, the number of measurement relative position processes that are being executed, etc.

[0103] In one embodiment of this disclosure, the first terminal responds to the priority information in the measurement relative position request sent by the second terminal, determines the first priority of the measurement relative position request, and determines whether to receive the measurement relative position request from the second terminal based on the first priority, the number of measurement relative position processes that can be executed simultaneously supported by the first terminal, and the number of measurement relative position processes that are being executed.

[0104] In this embodiment, the first terminal may terminate any currently executing relative position measurement process and receive a relative position measurement request from the second terminal if the number of simultaneous relative position measurement processes supported by the first terminal is equal to the number of relative position measurement processes currently being executed, and the second priority of any currently executing relative position measurement process is lower than the first priority.

[0105] Optionally, the first terminal may reject the second terminal's relative position measurement request if the number of simultaneous relative position measurement processes supported by the first terminal is equal to the number of relative position measurement processes currently being executed, and the second priority of the relative position measurement processes currently being executed is higher than the first priority.

[0106] In the embodiments of this disclosure, the first terminal may determine whether to receive the measurement relative position request based on the first priority of the measurement relative position request from the second terminal, the number of measurement relative position processes that the first terminal supports performing simultaneously, and the number of measurement relative position processes that are being executed. Thus, the terminal may determine whether to receive the new measurement relative position request based on the priority of the new measurement relative position request and its own processing capabilities.

[0107] Figure 2 This is a flowchart illustrating another method for measuring relative position provided in an embodiment of the present disclosure. This method for measuring relative position can be executed by a first terminal to determine whether to receive a relative position measurement request based on a first priority of the relative position measurement request.

[0108] like Figure 2 As shown, the method for measuring relative position includes:

[0109] Step 201: In response to the priority information in the measurement relative position request sent by the second terminal, determine the first priority of the measurement relative position request.

[0110] In related technologies, based on the machine-to-machine (MTB) sidelink technology, the edge connection sidelink interface between terminals is called the PC5 interface. The sidelink control plane supports two protocols: the PC5 signaling protocol (PC5-S) and the RRC protocol.

[0111] In this embodiment, the second terminal can carry a measurement relative position request through a PC5 RRC message or a PC5 schematic message and send the measurement relative position request to the first terminal.

[0112] In this embodiment, priority information may include at least one of business-related information and business priority.

[0113] As one implementation, the priority information includes service priority information. The first terminal responds to the service priority information in the priority information to determine the first priority of the measurement relative position request sent by the second terminal. The higher the service priority, the higher the first priority of the measurement relative position request.

[0114] As another implementation, the priority information includes business-related information. The first terminal can respond to the business-related information in the priority information to determine the first priority of the measurement relative position request sent by the second terminal.

[0115] Optionally, the service-related information may include at least one of the following: operating system identifier, application identifier, service type, and latency requirements. The operating system identifier is the identifier of the operating system of the second terminal; the application identifier is the identifier of the application in the second terminal that sent the relative location measurement request; and the service type is the service type to which the location measurement service belongs, such as emergency service, vehicle-to-everything (V2X) service, or smart home service.

[0116] The first terminal may determine the first priority of the relative position measurement request in response to the delay requirement in the first priority message information, wherein the higher the delay requirement, the higher the first priority of the relative position measurement request. Alternatively, the first terminal may determine the first priority of the relative position measurement request in response to the operating system identifier and the first terminal's operating system identifier in the first priority message information. For example, if the second terminal's operating system is the same as the first terminal's operating system, the determined first priority is higher; if the second terminal's operating system is different from the first terminal's operating system, the first priority is higher.

[0117] Step 202: In response to the absence of a currently executing measurement relative position process, receive a measurement relative position request; or, in response to the second priority of the currently executing measurement relative position process being lower than the first priority, terminate the currently executing measurement relative position process and receive a measurement relative position request; or, in response to the second priority of the currently executing measurement relative position process being higher than or equal to the first priority, reject the measurement relative position request.

[0118] In this embodiment, the first terminal may receive a relative position measurement request from the second terminal in response to the absence of a current relative position measurement process.

[0119] Optionally, the first terminal may terminate the ongoing measurement relative position process and receive a measurement relative position request from the second terminal in response to the second priority of the ongoing measurement relative position process being lower than the first priority. The ongoing measurement relative position process with the second priority being lower than the first priority may be one or more.

[0120] Optionally, the first terminal may reject the second terminal's request to measure relative position in response to the second terminal having a higher or equal priority than the first priority in the ongoing process of measuring relative position.

[0121] In this embodiment, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal, wherein the rejection message includes a reason for rejection. For example, the reason for rejection may be that the priority is lower than the currently executing measurement relative position process. Thus, the second terminal can know the reason why the first terminal rejected its measurement relative position request.

[0122] Optionally, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal, wherein the rejection message includes a waiting time to instruct the second terminal to re-initiate the request to measure relative position after the waiting time. Thus, the second terminal can, based on the rejection message, resend the request to measure relative position to the first terminal after the waiting time.

[0123] The waiting time can be determined by the first terminal based on the number of relative position measurement processes being performed.

[0124] Optionally, in response to rejecting the second terminal's request to measure the relative position, the rejection message returned by the first terminal to the second terminal may also include information such as the reason for rejection and the waiting time.

[0125] The method for measuring relative position according to embodiments of this disclosure determines a first priority of the measurement relative position request in response to priority information in the measurement relative position request sent by a second terminal; receives the measurement relative position request in response to the absence of a currently executing measurement relative position process; or terminates the currently executing measurement relative position process and receives the measurement relative position request in response to the second priority of the currently executing measurement relative position process being lower than the first priority; or rejects the measurement relative position request in response to the second priority of the currently executing measurement relative position process being higher than or equal to the first priority. Thus, the terminal determines whether to receive a new measurement relative position request based on its priority.

[0126] In one embodiment of this disclosure, the first terminal may also obtain priority configuration information sent by the network element. The configuration information includes service-related information and corresponding priority information. Each type of service-related information may include at least one of the following: operating system identifier, application identifier, service type, and latency requirements.

[0127] In this embodiment, the first terminal can determine the first priority of the measurement relative position request based on the priority configuration information and the measurement relative position request of the second terminal, and determine whether to accept the measurement relative position request of the second terminal based on the first priority.

[0128] For example, the priority configuration information includes the service type and the priority corresponding to each service type. The first terminal can determine the priority corresponding to the service type carried in the measurement relative location request based on the service type carried in the measurement relative location request and the service type and corresponding priority included in the priority configuration information, and determine the first priority of the measurement relative location request based on the priority corresponding to the service type carried in the measurement relative location request.

[0129] For example, the priority configuration information includes three service types A, B, and C. Service type A has the highest priority, followed by B, and C has the lowest priority. The service type carried in the measurement relative position request of the second terminal is A. The first terminal can determine the priority of the measurement relative position request as the highest priority based on the service types A, B, and C and their corresponding priorities, and the service type A carried in the measurement relative position request.

[0130] The method for measuring relative position in this embodiment of the present disclosure obtains priority configuration information sent by a network element, determines a first priority of the measurement relative position request based on the priority configuration information and the priority information in the measurement relative position request sent by a second terminal, and determines whether to receive the measurement relative position request based on the first priority, thereby realizing the determination of whether to receive a new measurement relative position request based on the configuration information sent by the network element.

[0131] In one embodiment of this disclosure, the first terminal may further determine whether to receive a relative position measurement request according to a first priority based on the frequency bands corresponding to the first terminal and the second terminal, respectively. The following is in conjunction with... Figure 3 and Figure 4 Please provide an explanation. Figure 3 This is a flowchart illustrating another method for measuring relative position provided in an embodiment of the present disclosure, which can be executed by a first terminal.

[0132] like Figure 3 As shown, the method for measuring relative position includes:

[0133] Step 301: Obtain the priority configuration information sent by the network element. The configuration information includes service-related information and corresponding priority information, and also includes the applicable frequency band.

[0134] In this embodiment, the first terminal can obtain priority configuration information sent by the network element. The priority configuration information sent by the network element may include service-related information and corresponding priority information, and may also include the applicable frequency band that the network element can provide.

[0135] In this embodiment, the applicable frequency bands included in the priority configuration information can be one or more.

[0136] Step 302: In response to the measurement relative position request sent by the acquired second terminal, determine the frequency band corresponding to the second terminal.

[0137] In this embodiment, the measurement relative position request sent by the second terminal may include information such as the frequency band and service type corresponding to the second terminal. In response to the obtained measurement relative position request sent by the second terminal, the frequency band corresponding to the second terminal can be determined.

[0138] Step 303: In response to the fact that the frequency bands corresponding to the second terminal and the first terminal are the same as the frequency bands in the configuration information, the first priority of the measurement relative position request is determined according to the priority information in the measurement relative position request.

[0139] In this embodiment, the first terminal compares its corresponding frequency band and the frequency band corresponding to the second terminal with the frequency band in the configuration information. In response to the fact that the frequency bands corresponding to both the second terminal and the first terminal are the same as the frequency bands in the configuration information, the first terminal determines the first priority of the measurement relative position request according to the priority information in the measurement relative position request.

[0140] In this embodiment, if the configuration information includes multiple frequency bands, the frequency bands corresponding to the second terminal and the first terminal are the same as the frequency bands in the configuration information. This can be either the frequency bands corresponding to the first terminal and the second terminal are the same and the corresponding frequency bands are the frequency bands in the configuration information, or the frequency bands corresponding to the first terminal and the second terminal are different and both the frequency bands corresponding to the first terminal and the second terminal are the frequency bands in the configuration information.

[0141] In this embodiment, the first priority of the relative position measurement request is determined according to the priority information in the relative position measurement request. This can be achieved by any of the methods in the various embodiments of this disclosure. This disclosure does not limit this method and will not elaborate further.

[0142] Step 304: Determine whether to accept the request to measure relative position based on the first priority.

[0143] In the embodiments of this disclosure, step 304 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0144] In this embodiment, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal. The rejection message includes a reason for rejection, such as the reason being that the priority of the relative position measurement request is lower than that of the currently executing relative position measurement process. Thus, the second terminal can know the reason why the first terminal rejected its relative position measurement request.

[0145] Optionally, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal, wherein the rejection message includes a waiting time to instruct the second terminal to re-initiate the request to measure relative position after the waiting time. Thus, the second terminal can, based on the rejection message, resend the request to measure relative position to the first terminal after the waiting time.

[0146] The waiting time can be determined by the first terminal based on the number of relative position measurement processes being performed.

[0147] Optionally, in response to rejecting the second terminal's request to measure the relative position, the rejection message returned by the first terminal to the second terminal may also include information such as the reason for rejection and the waiting time.

[0148] The method for measuring relative position according to this embodiment of the present disclosure obtains priority configuration information sent by a network element, wherein the configuration information may also include an applicable frequency band. In response to the fact that the frequency bands corresponding to the second terminal and the first terminal are the same as the frequency bands in the configuration information, the method determines whether to receive a new relative position measurement request by using the priority of the relative position measurement request.

[0149] Figure 4 This is a flowchart illustrating another method for measuring relative position provided in an embodiment of the present disclosure, which can be executed by a first terminal.

[0150] like Figure 4 As shown, the method for measuring relative position includes:

[0151] Step 401: Obtain the priority configuration information sent by the network element. The configuration information includes service-related information and corresponding priority information, and also includes the applicable frequency band.

[0152] In this embodiment, step 401 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this implementation and will not elaborate further.

[0153] Step 402: In response to the measurement relative position request sent by the acquired second terminal, determine the frequency band corresponding to the second terminal.

[0154] In this embodiment, step 402 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this implementation and will not elaborate further.

[0155] Step 403: In response to the fact that the frequency band corresponding to the second terminal is different from the frequency band in the configuration information, the first priority of the measurement relative position request is determined according to the priority information in the measurement relative position request.

[0156] In this embodiment, the first terminal can compare the frequency band corresponding to the second terminal with the frequency band in the configuration information. In response to the difference between the frequency band corresponding to the second terminal and the frequency band in the configuration information, the first priority of the measurement relative position request is determined according to the priority information in the measurement relative position request.

[0157] If the configuration information includes multiple frequency bands, the frequency band corresponding to the second terminal is different from the frequency band in the configuration information. This means that the frequency band corresponding to the second terminal is different from each frequency band in the configuration information. In other words, the frequency band used by the second terminal is not the frequency band in the configuration information.

[0158] In this embodiment, the first priority of the relative position measurement request is determined based on the priority information in the relative position measurement request. This can be achieved by any of the methods in the various embodiments of this disclosure. This disclosure does not limit this method and will not elaborate further.

[0159] Step 404: Determine whether to accept the request to measure relative position based on the first priority.

[0160] In this embodiment, step 404 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this implementation and will not elaborate further.

[0161] In this embodiment, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal. The rejection message includes a reason for rejection, such as a lower priority than the currently executing measurement relative position process. Thus, the second terminal can know the reason why the first terminal rejected its measurement relative position request.

[0162] Optionally, in response to rejecting the second terminal's request to measure relative position, the first terminal may return a rejection message to the second terminal, wherein the rejection message includes a waiting time to instruct the second terminal to re-initiate the request to measure relative position after the waiting time. Thus, the second terminal can, based on the rejection message, resend the request to measure relative position to the first terminal after the waiting time.

[0163] The waiting time can be determined by the first terminal based on the number of relative position measurement processes being performed.

[0164] Optionally, in response to rejecting the second terminal's request to measure the relative position, the rejection message returned by the first terminal to the second terminal may also include information such as the reason for rejection and the waiting time.

[0165] The method for measuring relative position according to this embodiment of the present disclosure obtains priority configuration information sent by a network element, wherein the configuration information may also include an applicable frequency band. In response to the fact that the frequency band corresponding to the second terminal is different from the frequency band in the configuration information, the method determines whether to receive a new relative position measurement request by utilizing the priority of the relative position measurement request.

[0166] Figure 5 This is a flowchart illustrating another method for measuring relative position provided in an embodiment of the present disclosure, which can be executed by a first terminal.

[0167] like Figure 5 The method for measuring relative position includes:

[0168] Step 501: In response to the priority information in the measurement relative position request sent by the second terminal, determine the first priority of the measurement relative position request.

[0169] In this embodiment, step 501 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0170] Step 502: Determine to receive a relative position measurement request based on the first priority.

[0171] In this embodiment, step 502 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this implementation and will not elaborate further.

[0172] Step 503: Determine the priority of the first data packet related to the relative position measurement request.

[0173] In this embodiment, after the first terminal receives the relative position measurement request from the second terminal, the first terminal can send a first data packet related to the relative position measurement request at the physical layer. The first data packet may be a data packet related to physical layer channel scheduling.

[0174] In this embodiment, the first data packet sent by the first terminal at the physical layer may carry priority information. Therefore, the priority of the first data related to the relative position measurement request can be determined based on the priority information carried in the first data packet.

[0175] Optionally, the first terminal may also determine the priority of the first data packet related to the measurement relative position request based on the first priority of the measurement relative position request. The higher the priority of the measurement relative position request, the higher the priority of the first data packet.

[0176] Step 504: Determine whether to transmit the first data packet based on the priority of the first data packet and the priority of the second data packet measuring the relative position that is being transmitted.

[0177] In this embodiment, in response to the simultaneous transmission of a first data packet and a second data packet measuring the relative position, it can be determined whether to transmit the first data packet based on the priority of the first data packet and the priority of the second data packet measuring the relative position.

[0178] Optionally, in response to the fact that the priority of the first data packet related to the relative position measurement request is lower than or equal to the priority of the second data packet being transmitted, the physical layer of the first terminal may refuse to transmit the first data packet and continue to transmit the second data packet.

[0179] Optionally, in response to the fact that the priority of the first data packet related to the relative position measurement request is higher than the priority of the second data packet, the physical layer of the first terminal may terminate the transmission of the second data packet and begin transmitting the first data packet related to the relative position measurement request.

[0180] The method for measuring relative position in this embodiment of the present disclosure determines whether to transmit the first data packet based on the priority of the first data packet related to the relative position measurement request and the priority of the second data packet related to the relative position measurement that is being transmitted, thereby enabling the transmission of data packets related to the relative position measurement request according to the priority of the data packets.

[0181] Figure 6This is a flowchart illustrating another method for measuring relative position provided in an embodiment of the present disclosure, which can be executed by a first terminal.

[0182] like Figure 6 As shown, the method for measuring relative position includes:

[0183] Step 601: In response to the priority information in the measurement relative position request sent by the second terminal, determine the first priority of the measurement relative position request.

[0184] In this embodiment, step 601 can be implemented in any of the ways described in the various embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0185] Step 602: Determine to receive a relative position measurement request based on the first priority.

[0186] In this embodiment, step 602 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this implementation and will not elaborate further.

[0187] Step 603: Determine the priority of the relevant interactive information for the relative position measurement request.

[0188] In this embodiment, the relevant interaction information refers to the information exchanged between the first terminal and the second terminal during the process of measuring the relative position according to the relative position measurement request. For example, the relevant interaction information may include information for measuring the relative position actively sent by the first terminal to the second terminal, the response returned by the second terminal to the first terminal, and the relative position measurement result returned by the first terminal to the second terminal.

[0189] In this embodiment, the first terminal can determine the priority of each relevant interactive information based on its role in the process of measuring relative position.

[0190] Step 604: Determine the logical channel corresponding to the relevant interaction information based on the priority of the relevant interaction information and the priority of each logical channel.

[0191] In this embodiment, the first terminal can assign different priorities to different logical channels. The first terminal can determine the logical channel corresponding to the relevant interaction information based on the priority of the relevant interaction information and the priority of each logical channel. Specifically, the higher the priority of the relevant interaction information, the higher the priority of the logical channel corresponding to the relevant interaction information.

[0192] After determining the logical channel corresponding to the relevant interaction information, the first terminal can use the logical channel corresponding to each relevant interaction information to send the relevant interaction information using a separate logical channel during the process of measuring the relative position.

[0193] In the embodiments of this disclosure, the logical channel corresponding to the relevant interactive information is determined according to the priority of the relevant interactive information and the priority of each logical channel, thereby realizing the priority control of the relevant interactive information based on the priority of the relevant interactive information and the priority of each logical channel.

[0194] The following examples illustrate the above embodiments:

[0195] Terminal A sends an angle / distance measurement request to terminal B, the request message carrying priority information. After receiving the request message from terminal A, if terminal B is currently performing a distance / angle measurement process with a higher priority than the request, it can reject the distance / angle measurement request.

[0196] If terminal b is currently performing a ranging / angle measurement process with a lower priority than this request, then terminal b can receive the ranging / angle measurement request and terminate the ongoing ranging / angle measurement process.

[0197] If terminal b has an ongoing ranging / angle measurement request, and if simultaneous ranging / angle measurement of the request is supported, then the ranging / angle measurement request can be received.

[0198] The ranging / angle measurement priority information includes service priority and / or latency requirements. Higher service priority corresponds to lower latency and thus higher ranging / angle measurement priority.

[0199] In this embodiment, the ranging / angle measurement request is sent via a PC5 RRC message or a PC5-S message (denoted as a PC5 schematic message). When the application layer of terminal a requests ranging / angle measurement from the PC5-S layer, it provides terminal b with PC5-S layer service-related information or priority information.

[0200] The business-related information includes one or more of the following: OS ID (operating system identifier), APPID (application identifier), business type (such as emergency business, vehicle networking business, smart home business, etc.), latency requirements, etc.

[0201] When making a ranging / angle measurement request, the PC5-S layer provides the PC5-RRC layer with ranging / angle measurement priority information.

[0202] In this embodiment, core network elements (such as AMF) can be configured with priority information for terminal b. This priority information includes the OS ID (Operating System ID), APP ID (Application ID), and corresponding priority information.

[0203] This priority information is used when terminal a and terminal b use the frequency provided by the operator for ranging / angle measurement.

[0204] Terminal b sends a priority information packet (SCI) related to the ranging / angle measurement process at the physical layer, which includes the SCI (sidelink control information). The SCI is used to send information related to the physical layer's sidelink channel scheduling. If the priority of the ranging / angle measurement information to be transmitted is higher than the priority of the currently ongoing ranging / angle measurement transmission, terminal b's physical layer can decide to terminate the current transmission and send the current ranging / angle measurement transmission; otherwise, terminal b's physical layer can continue the current transmission.

[0205] The ranging / angle measurement related message exchange between terminal A and terminal B uses a separate logical channel and optionally a separate SRB / DRB (signaling bearer / data bearer). Multiple ranging / angle measurement processes between terminal A and terminal B can also use separate logical channels and optionally separate SRB / DRBs. Therefore, the terminal can assign different priorities to different logical channels, thereby achieving priority control between different ranging / angle measurement processes and between ranging / angle measurement interactions and other data / signaling information.

[0206] If terminal B rejects terminal A's ranging / angle measurement request because there is a high-priority ranging / angle measurement process currently in operation, the reason for rejection can be specified in the rejection message, such as the existence of a high-priority ranging / angle measurement process.

[0207] If terminal B rejects terminal A's ranging / angle measurement request because it has a higher-priority ranging / angle measurement process at hand, the rejection message specifies the waiting time. Terminal A can then initiate the ranging / angle measurement request again after the waiting time.
