Optionally, the communication system in the embodiment of the present application may be applied to a carrier aggregation (Carrier Aggregation, CA) scenario, a dual connectivity (Dual Connectivity, DC) scenario, and a Stand Alone (SA) fabric scenario.

Referring to fig. 1, fig. 1 is a schematic architecture diagram of a data transmission system according to an embodiment of the present application. The data transmission system provided in this embodiment includes a terminal 101, a terminal 102, and a network device 103.

Alternatively, the terminals 101, 102 may be various forms of user equipment, access terminals, subscriber units, subscriber stations, mobile Stations (MSs), remote stations, remote terminals, mobile devices, terminal equipment (terminal equipment), wireless communication devices, user agents, or user equipment. But also cellular phones, cordless phones, session initiation protocol (Session Initiation Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, palm top computers (Personal Digital Assistant, PDA), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, car-mounted devices, wearable devices, terminal devices in future 5G networks or terminal devices in future evolving public land mobile communication networks (Public Land Mobile Network, PLMNs), etc., as long as the terminal is capable of wireless communication with network device 103.

Optionally, the network device 103, i.e. public mobile communication network device, is an interface device of the terminals 101 and 102 accessing the internet, and is also a form of a radio Station, which refers to a radio transceiver Station for performing information transfer with the terminals 101 and 102 in a certain radio coverage area, and includes a Base Station (BS), which may also be referred to as a Base Station device, and is a device deployed in the radio access network (Radio Access Network, RAN) to provide a wireless communication function. For example, the device for providing a base station function in the 2G network includes a base radio transceiver station (Base Transceiver Station, BTS), the device for providing a base station function in the 3G network includes a node B (NodeB), the device for providing a base station function in the 4G network includes an evolved NodeB (eNB), the device for providing a base station function in the wireless local area network (Wireless Local Area Networks, WLAN) is an Access Point (AP), the device for providing a base station function in the 5G NR is a next generation evolved NodeB (the next Generation Node B, gNB), and the node B (next generation-eNodeB, ng-eNB) that continues to evolve, wherein the gNB and the terminal communicate using NR technology, and the ng-eNB and the terminal communicate using evolved universal terrestrial radio Access network (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and the gNB and the ng-eNB are both connectable to the 5G core network. The network device 103 in the embodiment of the present application also includes a device that provides a base station function in a new communication system in the future, and the like.

The embodiment of the application defines a unidirectional communication link from an access network to a terminal as Downlink (DL), wherein data transmitted on the Downlink is Downlink data, and the transmission direction of the Downlink data is called as Downlink direction; the unidirectional communication link from the terminal to the access network is Uplink (UL), the data transmitted on the Uplink is Uplink data, and the transmission direction of the Uplink data is called as Uplink direction; the terminal may also communicate directly with the terminal, the link between the terminal and the terminal being SL.

With further evolution of the fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) technology, the third generation partnership project (3rd Generation Partnership Project,3GPP) will conduct SL based positioning studies. In the current V2X protocol, SL does not support transmission of positioning related reference signals, such as positioning reference signals (Positioning Reference Signal, PRS) or sounding reference signals (Sounding Reference Signal, SRS).

In the existing cellular network, for downlink PRS, a terminal completes positioning measurement and reporting by measuring PRS sent by a Transmission-Reception Point (TRP), each TRP is configured with a dedicated positioning resource, i.e., each TRP corresponds to one or more PRS resource pools, and the terminal can determine from which TRP the currently measured PRS comes by the resource pool where the PRS is located. For SRS transmission in the cellular network, the network configures dedicated SRS resources for the terminal, and the terminal transmits SRS on each specific resource to realize uplink positioning.

In SL positioning (where a terminal performs positioning measurement through SL), it is difficult to preset dedicated transmission resources for transmitting positioning reference signals for each terminal because the transmission resources in the resource pool are relatively tight, so that the terminal needs to perform resource sensing and resource selection in the resource pool to determine the transmission resources for transmitting positioning reference signals.

Referring to fig. 2, fig. 2 is a schematic configuration diagram of a resource pool according to an embodiment of the present application. In fig. 2, the granularity of the time domain of the resource pool is a slot (slot), and the granularity of the frequency domain is a subchannel (sub-channel); one subshannel contains m Resource Blocks (RBs), where m is high-level configured.

When the terminal selects the resources, if it is determined that the L sub-channels are required to transmit according to the size of the data packet, the transmission resources are continuous L sub-channels in a slot in the resource pool. As in fig. 2, one transmission resource is l=3. Wherein each transmission resource transmits a physical side uplink control channel (Physical Sidelink Control Channel, PSCCH) and a physical side uplink shared channel (Physical Sidelink Shared Channel, PSSCH) simultaneously. Wherein the PSCCH carries SCI, and the PSSCH carries data to be transmitted. The SCI includes time-frequency domain location information of the current resource and time-frequency domain location information of a resource reserved later, and also includes some parameters of a decoding data channel (PSSCH). The frequency domain starting position of PSCCH resource in each transmission is the same as that of PSSCH resource, when PSCCH resource is detected, the frequency domain starting position of current PSSCH can be known, and decoding SCI can obtain information carried by the PSCCH resource.

In some embodiments, when a terminal transmits data, the terminal may autonomously select a transmission resource in a resource selection window, and because a resource pool is shared by a plurality of terminals, the terminal excludes an unavailable resource in the resource selection window, for example, a resource occupied by other terminals, a resource whose reference signal received power does not meet a condition, and the like, by using a sensing result in the resource sensing window, then selects a resource from available resources for transmission of a current Transport Block (TB) (for example, transmission pssch+pscch), and performs periodic reservation of the resource. When the next TB of the terminal arrives, the transmission is directly carried out on the reserved resource, and the resource selection is not needed.

For example, in a Round Trip Time (RTT) -based positioning method, both a target terminal (i.e., a terminal requiring positioning) and an anchor terminal (i.e., a terminal assisting in positioning of the target terminal) need to perform transmission and reception of positioning reference signals. For example, the second terminal needs to send the positioning reference signal to the first terminal, the first terminal needs to send the positioning reference signal to the second terminal after receiving the positioning reference signal sent by the second terminal, and finally the second terminal receives the positioning reference signal sent by the first terminal. In this process, both the first terminal and the second terminal need to perform resource sensing and resource selection in the resource pool to determine the transmission resource for transmitting the positioning reference signal, which inevitably brings additional power consumption to the terminal.

In view of the above technical problems, the present application provides a communication method, in which a second terminal sends a first positioning reference signal and first indication information to a first terminal, where the first indication information is used to indicate transmission resources of the second positioning reference signal and/or transmission resources of measurement results of the first positioning reference signal; and the first terminal sends a second positioning reference signal and/or a measurement result of the first positioning reference signal to the second terminal according to the first indication information. Because the first terminal transmits the transmission resource of the second positioning reference signal and/or transmits the transmission resource of the measurement result of the first positioning reference signal, which is indicated by the second terminal, the first terminal does not need to perform resource sensing and resource selection in the resource pool corresponding to the positioning reference signal, thereby effectively reducing the power consumption of the first terminal. The following will explain in detail the embodiments.

Alternatively, the first positioning reference signal and the second positioning reference signal in the present application may be PRS, SRS, SL PRS, SL SRS, or the like, which is not limited in the present application.

Referring to fig. 3, fig. 3 is a flow chart of a communication method provided in an embodiment of the present application, and in a possible implementation manner, the method includes:

S301, the second terminal determines a first periodic reserved resource in a resource pool corresponding to the positioning reference signal.

In some embodiments, when the second terminal has a positioning requirement, the second terminal may switch from the resource pool of the current data transmission to the resource pool corresponding to the positioning reference signal to perform resource sensing and resource selection, and determine the first periodic reserved resource through the resource sensing and resource selection process. The first periodic reserved resource includes at least one reserved resource.

Optionally, when the second terminal performs resource sensing and resource selection, the second terminal may perform resource reservation based on the related information of the first terminal. The related information of the first terminal includes configuration information of the first terminal receiving the positioning reference signal, and the like, so that the first terminal can be ensured to receive the first positioning reference signal on the first periodic reserved resource.

The resource pool corresponding to the positioning reference signal is a resource pool for positioning reference signal transmission. The resource pool corresponding to the positioning reference signal is a resource pool shared by a plurality of terminals including the second terminal and the first terminal. Each terminal selects and/or reserves a resource for transmitting the positioning reference signal from available resources (or called candidate resources) in the resource pool through resource awareness and resource selection. Specifically, the terminal may perform resource sensing in the resource sensing window, so as to determine available resources in the resource selection window, and select resources for transmitting the positioning reference signal from the available resources.

The transmission in the embodiments of the present application includes transmission and/or reception.

S302, the second terminal sends second indication information to the first terminal, where the second indication information is used to indicate the first periodically reserved resource (that is, the second indication information may also be understood as configuration information of the first periodically reserved resource). Accordingly, the first terminal receives the second indication information from the second terminal.

In some embodiments, the second terminal determines, in a resource pool of data transmission, transmission resources through a resource sensing and selecting procedure, so as to send the second indication information to the first terminal through a higher layer signaling.

Optionally, the higher layer signaling may be a radio resource Control (Radio Resource Control, RRC) message and/or a media access Control (Media Access Control, MAC) Control Element (CE).

S303, the first terminal determines a first periodic reserved resource indicated by the second indication information in a resource pool corresponding to the positioning reference signal according to the second indication information.

S304, the second terminal sends a first positioning reference signal and first indication information to the first terminal. Correspondingly, the first terminal receives the first positioning reference signal and the first indication information.

For example, the second terminal may transmit the first positioning reference signal and the first indication information to the first terminal using the first periodic reserved resource. Correspondingly, the first terminal may utilize the first periodic reserved resource to receive the first positioning reference signal and the first indication information.

Wherein the transmission resource of the first positioning reference signal (i.e. the resource used for transmitting the first positioning reference signal) is a reserved resource of the first periodic reserved resources. For example, resources may be reserved nearest to the first positioning reference signal to be transmitted.

Optionally, the second terminal may send the first positioning reference signal and the first indication information on the first periodic reserved resource at the same time (i.e. the first positioning reference signal and the first indication information adopt the same reserved resource); the first positioning reference signal and the first indication information may be sent in a time sharing manner on the first periodic reserved resource (i.e., the first positioning reference signal and the first indication information adopt different reserved resources). The first indication information is used for indicating a transmission resource of a measurement result of the first positioning reference signal sent by the first terminal and/or a transmission resource of the second positioning reference signal.

Alternatively, the first indication information may be carried in the SCI.

S305, the first terminal determines transmission resources for transmitting the measurement result of the first positioning reference signal and/or transmission resources for transmitting the second positioning reference signal according to the first indication information.

In some embodiments, if the first indication information does not indicate the transmission resource of the second positioning reference signal, the first terminal needs to determine, in a resource pool corresponding to the positioning reference signal, transmission resources for transmitting the second positioning reference signal through a process of resource awareness and resource selection.

In some embodiments, if the first indication information does not indicate the transmission resource of the measurement result of the first positioning reference signal, the first terminal needs to determine the transmission resource of the measurement result of the first positioning reference signal through a process of resource sensing and resource selection in a resource pool corresponding to the positioning reference signal.

And S306, the first terminal sends the measurement result of the first positioning reference signal and/or the second positioning reference signal to the second terminal according to the first indication information.

Wherein the first terminal may transmit the second positioning reference signal to the second terminal using the determined transmission resources for transmitting the second positioning reference signal.

Alternatively, the first terminal may transmit the measurement result of the first positioning reference signal to the second terminal using the determined transmission resource to transmit the measurement result of the first positioning reference signal.

Still alternatively, the first terminal may transmit the measurement result of the first positioning reference signal and the second positioning reference signal to the second terminal by using the determined transmission resources for transmitting the first positioning reference signal and the second positioning reference signal, respectively.

The steps 301, 302, 303, 305 are optional steps.

According to the communication method provided by the embodiment of the application, as the transmission resource of the second positioning reference signal sent by the first terminal and/or the transmission resource of the measurement result of the first positioning reference signal sent by the first terminal are indicated by the second terminal, the first terminal can not need to perform resource sensing and resource selection in the resource pool corresponding to the positioning reference signal, so that the power consumption of the first terminal can be effectively reduced.

The first indication information may be implemented in a variety of different forms based on what has been described in the above embodiments.

The first indication information may be used to indicate transmission resources of the second positioning reference signal in any of the following embodiments one to four.

Embodiment one:

the first indication information is specifically configured to indicate whether the transmission resource of the second positioning reference signal is a next reserved resource of the transmission resource of the first positioning reference signal. The next reserved resource is a next reserved resource of the transmission resource of the first positioning reference signal in the first periodic reserved resource.

When the first indication information indicates that the first terminal can send the second positioning reference signal by using the next reserved resource, the first terminal sends the second positioning reference signal to the second terminal by using the next reserved resource. When the first indication information indicates that the first terminal cannot send the second positioning reference signal by using the next reserved resource, the first terminal needs to determine the transmission resource of the first terminal for sending the second positioning reference signal through a process of resource sensing and resource selection in a resource pool corresponding to the positioning reference signal. Alternatively, the first indication information may be carried by the SCI, for example, a bit field of the first indication information may be set in the SCI.

Alternatively, the bit field of the first indication information may include 1 bit.

For example, when 1 bit in the bit field of the first indication information is 1, the first terminal may be instructed to transmit the second positioning reference signal to the second terminal using the next reserved resource, and when 1 bit in the bit field of the first indication information is 0, it indicates that the first terminal may not transmit the second positioning reference signal to the second terminal using the next reserved resource.

For a better understanding of the embodiments of the present application, referring to fig. 4, fig. 4 is a schematic diagram of positioning reference signal transmission provided in the embodiments of the present application.

As shown in fig. 4, when the first terminal receives the first positioning reference signal sent by the second terminal on the first periodic reserved resource, it is determined whether the second positioning reference signal can be sent to the second terminal by using the next reserved resource according to the first indication information. If the first indication information indicates that the first terminal can transmit the second positioning reference signal to the second terminal by using the next reserved resource, the first terminal transmits the second positioning reference signal to the second terminal by using the next reserved resource.

Embodiment two:

the first indication information is specifically configured to indicate that the transmission resource of the second positioning reference signal is a reserved resource next to the transmission resource of the first positioning reference signal.

Alternatively, the first indication information may be carried by the SCI, for example, a bit field of the first indication information may be set in the SCI.

In one case, when the bit field exists, it indicates that the transmission resource of the second positioning reference signal is the next reserved resource of the transmission resource of the first positioning reference signal, and when the bit field does not exist, it indicates that the transmission resource of the second positioning reference signal is not the next reserved resource of the transmission resource of the first positioning reference signal.

In another case, when the value of the bit field is a specific value, it indicates that the transmission resource of the second positioning reference signal is the reserved resource next to the transmission resource of the first positioning reference signal. The bit field may comprise 1 bit. When the 1 bit has a value of 1 (i.e. the specific value is 1), it indicates that the transmission resource of the second positioning reference signal is the reserved resource next to the transmission resource of the first positioning reference signal. For other descriptions of the second embodiment, reference may be made to the first embodiment, and no further description is given.

Embodiment III:

the first indication information may also be used to indicate that the transmission resource of the second positioning reference signal is a kth reserved resource after the transmission resource of the first positioning reference signal. The K reserved resource is a K reserved resource after the transmission resource of the first positioning reference signal in the first periodic reserved resource, and K is an integer greater than 0.

Alternatively, the bit field of the first indication information may include X bits.

Illustratively, when K is 1, X may be 1; when K is an integer of 2 or more, X is an integer of 2 or more.

For example, when X is 2, if the two bits are 10, it indicates that the first terminal may send the second positioning reference signal to the second terminal by using the 2 nd reserved resource; if the two bits are 11, it indicates that the first terminal can send the second positioning reference signal to the second terminal by using the 3 rd reserved resource.

For a better understanding of the embodiments of the present application, reference is made to fig. 5, and fig. 5 is a schematic diagram of another positioning reference signal transmission provided in the embodiments of the present application.

In fig. 5, k=3.

If the X bits (for example, the X bits have a value of 0000) in the bit field of the first indication information indicate that the first terminal can utilize the 0 th reserved resource, the first terminal needs to determine, in a resource pool corresponding to the positioning reference signal, a transmission resource for transmitting the second positioning reference signal through a process of resource sensing and resource selection, and then transmit the second positioning reference signal to the second terminal by using the determined transmission resource.

Embodiment four:

when the second terminal has positioning requirements, the second terminal can switch from the current resource pool of data transmission to the resource pool corresponding to the positioning reference signal to perform resource sensing and resource selection, and the second periodic reserved resource is determined through the resource sensing and resource selection process.

Optionally, when the second terminal performs resource sensing and resource selection, the second terminal may perform resource reservation based on information related to the first terminal, where the information related to the first terminal includes configuration information of the first terminal for receiving and transmitting the positioning reference signal, and so on.

In some embodiments, the first indication information is used to indicate resource information of the second periodic reserved resource (which is equivalent to a set of optional transmission resources indicating one second positioning reference signal), and the first terminal may determine the transmission resource of the second positioning reference signal from the second periodic reserved resource, and send the second positioning reference signal to the second terminal using the transmission resource. Wherein the illustrated resource information includes a frequency domain location (e.g., a starting subchannel, a number of occupied subchannels, etc.) and a time domain location (e.g., a slot index) of the second periodically reserved resource.

According to the communication method provided by the embodiment of the application, as the transmission resource of the first terminal for sending the second positioning reference signal is indicated by the second terminal, the first terminal does not need to perform resource sensing and resource selection in the resource pool corresponding to the positioning reference signal, so that the power consumption of the first terminal can be effectively reduced.

The first indication information may be used to indicate transmission resources of the measurement result of the first positioning reference signal in any of the following embodiments five to eight.

Fifth embodiment:

the first indication information is specifically configured to indicate whether a transmission resource of the measurement result of the first positioning reference signal is a reserved resource next to the transmission resource of the first positioning reference signal. Wherein the next reserved resource is a next reserved resource of the transmission resource of the first positioning reference signal in the first periodic reserved resource.

When the first indication information indicates that the first terminal can use the next reserved resource to send the measurement result of the first positioning reference signal, the first terminal uses the next reserved resource to send the measurement result of the first positioning reference signal to the second terminal. When the first indication information indicates that the first terminal cannot use the next reserved resource to send the measurement result of the first positioning reference signal, the first terminal needs to determine the transmission resource of the measurement result of the first positioning reference signal sent by the first terminal through the process of resource sensing and resource selection in the resource pool corresponding to the positioning reference signal.

For example, when 1 bit in the bit field of the first indication information is 1, the first terminal may be indicated to transmit the measurement result of the first positioning reference signal to the second terminal using the next reserved resource, and when the 1 bit is 0, it indicates that the first terminal may not transmit the measurement result of the first positioning reference signal to the second terminal using the next reserved resource.

For a better understanding of the embodiments of the present application, referring to fig. 6, fig. 6 is a schematic diagram illustrating transmission of measurement results of a positioning reference signal provided in the embodiments of the present application.

In fig. 6, the first indication information indicates that the first terminal may transmit the measurement result of the first positioning reference signal to the second terminal using the next reserved resource.

Embodiment six:

the first indication information is specifically configured to indicate that the transmission resource of the measurement result of the first positioning reference signal is a reserved resource next to the transmission resource of the first positioning reference signal.

In one case, the transmission resource representing the measurement result of the first positioning reference signal is a next reserved resource of the transmission resource of the first positioning reference signal when the bit field exists, and the transmission resource representing the measurement result of the first positioning reference signal is not a next reserved resource of the transmission resource of the first positioning reference signal when the bit field does not exist.

In another case, when the value of the bit field is a specific value, the transmission resource indicating the measurement result of the first positioning reference signal is the next reserved resource of the transmission resource of the first positioning reference signal. For example, the bit field may comprise 1 bit. When the 1-bit value is 1 (i.e., the specific value is 1), the transmission resource indicating the measurement result of the first positioning reference signal is the reserved resource next to the transmission resource of the first positioning reference signal.

For other descriptions of the second embodiment, reference may be made to the first embodiment, and no further description is given.

Embodiment seven:

the first indication information may be further used to indicate that the transmission resource of the measurement result of the first positioning reference signal is a kth reserved resource after the transmission resource of the first positioning reference signal. The transmission resource of the first positioning reference signal is one of the first periodic reserved resources, the Kth reserved resource is the Kth reserved resource after the transmission resource of the first positioning reference signal in the first periodic reserved resources, and K is an integer larger than 0.

It should be noted that, when the first indication information indicates that the transmission resource of the second positioning reference signal is the kth reserved resource after the transmission resource of the first positioning reference signal, and also indicates that the transmission resource of the measurement result of the first positioning reference signal is the kth reserved resource after the transmission resource of the first positioning reference signal, the values of the two K are different.

When K is 1, the above X may be 1; when K is an integer greater than or equal to 2, X may be an integer greater than or equal to 2.

For example, when X is 2, if the two bits are 10, it indicates that the first terminal may send the measurement result of the first positioning reference signal to the second terminal by using the 2 nd reserved resource; if the two bits are 11, it indicates that the first terminal can send the measurement result of the first positioning reference signal to the second terminal by using the 3 rd reserved resource.

For a better understanding of the embodiments of the present application, referring to fig. 7, fig. 7 is a schematic diagram illustrating transmission of measurement results of another positioning reference signal provided in the embodiments of the present application.

In fig. 7, k=3.

In some embodiments, if the X bits (assuming that the value of X is 4) in the bit field of the first indication information is 0000, it indicates that the first terminal may use the 0 th reserved resource to send the measurement result of the first positioning reference signal, at this time, the first terminal needs to determine, in the resource pool corresponding to the positioning reference signal, the transmission resource through the resource sensing and resource selecting process, and then send the measurement result of the first positioning reference signal to the second terminal by using the determined transmission resource.

Embodiment eight:

when the second terminal needs to send the first positioning reference signal to the first terminal, the second terminal can switch from the current resource pool of data transmission to the resource pool corresponding to the positioning reference signal to perform resource sensing and resource selection, and the third periodic reserved resource is determined through the resource sensing and the resource selection.

In some embodiments, the first indication information is used to indicate the resource information of the third periodic reserved resource (which is equivalent to a set of optional transmission resources indicating a measurement result of the first positioning reference signal sent by the first terminal), and the first terminal may determine the transmission resource of the measurement result of the first positioning reference signal from the third periodic reserved resource, and send the measurement result of the first positioning reference signal to the second terminal by using the transmission resource. The resource information includes, among others, the frequency domain location (e.g., frequency domain start RB, bandwidth, etc.), time domain location (e.g., slot index) of the third periodically reserved resource described above.

In some embodiments, if the first indication information does not indicate the third periodic reserved resource, the first terminal needs to determine, in a resource pool corresponding to the positioning reference signal, transmission resources for transmitting the measurement result of the first positioning reference signal through a process of resource awareness and resource selection.

According to the communication method provided by the embodiment of the application, as the transmission resource of the measurement result of the first positioning reference signal sent by the first terminal is indicated by the second terminal, the first terminal can avoid the need of carrying out resource sensing and resource selection in the resource pool corresponding to the positioning reference signal, so that the power consumption of the first terminal can be effectively reduced.

And 2, the first terminal transmits the second positioning reference signal by adopting the transmission parameters of the second positioning reference signal.

In case 2, the second terminal may send third indication information to the first terminal when sending the first positioning reference signal (i.e. the third indication information and the first positioning reference signal use the same transmission resource), where the third indication information is used to indicate the transmission parameter of the second positioning reference signal.

Optionally, the above transmission parameters include one or more of the following:

the frequency domain resource position of the positioning reference signal resource, the initial time slot/symbol of the positioning reference signal resource, the symbol number occupied by the positioning reference signal resource, the resource unit offset of the positioning reference signal resource, the pattern of the positioning reference signal resource and the like. The resource unit offset of the positioning reference signal resource includes an index of a resource unit occupied by a first symbol of the positioning reference signal resource, that is, an offset between a position of the resource unit where the positioning reference signal on the other symbol is located and a position of the resource unit where the positioning reference signal on the first symbol is located.

Optionally, the third indication information may be carried by the SCI, for example, some or all of the following indication bit fields may be set in the SCI:

a frequency domain resource location indication bit domain of the positioning reference signal resource;

the starting slot/symbol of the positioning reference signal resource indicates a bit field;

the number of symbols occupied by the positioning reference signal resource indicates a bit domain;

a resource element offset indication bit field of the positioning reference signal resource;

The transmission parameters may be carried in the SCI.

In addition, the transmission parameter employed by the first terminal when transmitting the measurement result of the first positioning reference signal may be the following case 3 or case 4.

And 3, the first terminal transmits the measurement result of the first positioning reference signal by adopting the transmission parameter of the first positioning reference signal. I.e. the first terminal transmits the measurement result of the first positioning reference signal along the transmission parameter of the second terminal transmitting the first positioning reference signal.

In case 3, the second terminal may transmit the transmission parameter of the first positioning reference signal to the first terminal when transmitting the first positioning reference signal (i.e., the transmission parameter of the first positioning reference signal and the first positioning reference signal use the same transmission resource).

And 4, the first terminal transmits the measurement result of the first positioning reference signal by adopting the transmission parameter of the measurement result of the first positioning reference signal.

In case 4, the second terminal may send third indication information (i.e., the third indication information and the first positioning reference signal use the same transmission resource) to the first terminal when sending the first positioning reference signal, where the third indication information is used to indicate a transmission parameter of the measurement result of the first positioning reference signal.

The third instruction information in case 2 and the third instruction information in case 4 may be the same instruction information or may be different instruction information.
