[0054] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0055] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure.

[0056] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0057] In order to better describe any embodiment of the present disclosure, an embodiment of the present disclosure is illustratively described by taking an application scenario of an electric meter intelligent control system as an example.

[0058] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several terminals 11 and several base stations 12.

[0059] Terminal 11 may refer to a device that provides voice and / or data connectivity to a user. Terminal 11 may communicate with one or more core networks via a radio access network (RAN). Terminal 11 may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, the terminal may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (terminal). Alternatively, terminal 11 may be a device on an unmanned aerial vehicle (UAV). Alternatively, terminal 11 may be an in-vehicle device, such as a vehicle-mounted computer with wireless communication capabilities, or a wireless terminal connected to an external vehicle-mounted computer. Alternatively, the terminal 11 may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with a wireless communication function.

[0060] The base station 12 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as a long-term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of the 5G system. The access network in the 5G system may be referred to as a New Generation-Radio Access Network (NG-RAN).

[0061] Among them, the base station 12 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 12 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 12 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a media access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the base station 12.

[0062] A wireless connection can be established between the base station 12 and the terminal 11 via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0063] In some embodiments, E2E (End to End) connections can also be established between terminals 11. For example, in vehicle-to-everything (V2X) communication scenarios such as V2V (vehicle to vehicle), V2I (vehicle to infrastructure), and V2P (vehicle to pedestrian).

[0064] In some embodiments, the wireless communication system may further include a network management device 13 .

[0065] Several base stations 12 are respectively connected to a network management device 13. The network management device 13 can be a core network device in a wireless communication system. For example, the network management device 13 can be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device can also be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

[0066] like Figure 2A As shown, an embodiment of the present disclosure provides a positioning method between user equipments UEs, wherein the method includes:

[0067] S110: receiving a relative position positioning request;

[0068] S120: According to the phase position positioning request, resource configuration is issued; wherein the resource configuration is used to configure transmission resources for the first UE and / or the second UE to send an uplink UL sounding reference signal SRS; wherein the UL SRS is used to determine the relative position between the first UE and the second UE.

[0069] For example, if a first UE is separately configured with transmission resources for sending a UL SRS, a second UE can measure the UL SRS sent by the first UE on the configured transmission resources to obtain a measurement result, which can be used by the second UE to determine its relative position to the first UE. If the first UE needs to know the relative position between itself and the second UE, the second UE can report its measured relative position to the base station, which then sends it to the first UE.

[0070] For another example, if a second UE is separately configured with transmission resources for sending UL SRS, the first UE can measure the UL SRS sent by the second UE on the configured transmission resources to obtain a measurement result, which can be used by the first UE to determine the relative position between itself and the second UE. If the second UE needs to know the relative position between itself and the first UE, the first UE can report its measured relative position to the base station, which then sends it to the second UE.

[0071] In another embodiment, the base station sends UL SRS configuration transmission resources to the first UE and the second UE respectively. Figure 2B As shown, the method may further include:

[0072] S130: Receive a second measurement result of the UL SRS sent by the second UE to the first UE;

[0073] S140: Send the second measurement result to the first UE; wherein the second measurement result is used together with the first measurement result of the UL SRS sent by the first UE to the second UE to determine the relative position between the first UE and the second UE.

[0074] UEs can locate each other, but this is done through direct device-to-device connections, which requires the UEs to support direct communication interfaces and increases the complexity of the UEs. In the disclosed embodiments, two UEs that need to locate each other need to complete relative positioning on the uplink Uu interface based on the positioning measurement resources allocated by the base station.

[0075] For example, the two UEs may be located in one cell, in adjacent cells, or in two non-adjacent cells.

[0076] This method is applied to a base station group, which may include one or more base stations. For example, if two UEs to be located are located in the same cell, the base station is the base station where the two UEs reside or are connected. If the two UEs are located in different cells, the base station group may include two adjacent base stations.

[0077] Of course, the above is only an example of an execution subject of the positioning method between UEs. In a specific implementation process, the positioning method between UEs can be applied to access devices of one or more access networks, of which a base station is one type of access device.

[0078] In the embodiment of the present disclosure, the base station participates in the resource configuration for the mutual positioning measurement between the first UE and the second UE, thereby reducing the poor wireless environment caused by the first UE and the second UE randomly selecting resources to send positioning reference signals, and the interference with the normal communication of other UEs, thereby improving the overall communication quality of the cellular cell.

[0079] In an embodiment of the present disclosure, the resources allocated by the base station side for the first UE and the second UE can both be UL SRS resources. Therefore, the first UE and the second UE will send UL SRS on the UL SRS resources according to the resource configuration, and measure the UL SRS transmitted by other UEs, thereby realizing the measurement of the relative position between the first UE and the second UE through signal measurement.

[0080] The relative positions between the UEs herein may include: a relative distance and a relative angle between the first UE and the second UE.

[0081] In the embodiment of the present disclosure, the first UE and the second UE reuse the UL SRS originally used for uplink positioning between the base station and the UE to perform relative positioning between the two UEs, which can be compatible with the cellular communication technology in the related technology to the greatest extent and has the characteristics of simple operation.

[0082] The first measurement result and the second measurement result may include at least one of the following:

[0083] RX-TXdifference;

[0084] Reference Signal Receiving Power (RSRP) of the received SRS;

[0085] Reference Signal Receiving Quality (RSRQ) of the received SRS;

[0086] Angle-of-Arrival (AOA) of the received SRS.

[0087] After either the first UE or the second UE receives the measurement result of the other UE, the relative position between the first UE and the second UE can be calculated based on its own measurement result.

[0088] In the embodiments of the present disclosure, the first UE may be: an initializing UE that initiates relative position measurement between UEs, or a target UE that participates in relative position measurement between UEs. Of course, the second UE may also be an initializing UE that initiates relative position measurement between UEs, or a target UE that participates in relative position measurement between UEs.

[0089] In summary, one of the first UE and the second UE is an initialization UE, and the other is a target UE.

[0090] After receiving the second measurement result of the second UE, the base station will forward the second measurement result to the first UE so that the first UE can calculate the relative position with the second UE. In this way, positioning measurement between UEs can be easily achieved while minimizing interference to cellular communications.

[0091] In some embodiments, the relative position positioning request includes identification information of the first UE, identification information of the second UE and a relative position measurement indication.

[0092] The relative positioning request may be issued by a network element of the core network, which may include but is not limited to an access management function (AMF) or a location management function (LMF).

[0093] The relative position positioning request may be formed by the inter-UE positioning request sent by the initializing UE. For example, after receiving the positioning request sent by the initializing UE, the AMF or LMF sends the aforementioned relative position positioning request to the base station.

[0094] The AMF or LMF will carry the identification information of the first UE and the second UE in the relative position positioning request, and will also provide a relative position measurement indication. In this way, after the base station receives the relative position positioning request, it can know that the relative position positioning request is used to locate the relative position between the two UEs, rather than the relative position between the UE and the base station, compared with the relative positioning request that only carries the identification information of one UE.

[0095] The relative position measurement indication indicates that the request is for relative positioning. At this time, after receiving the relative position positioning request, the base station will schedule positioning resources according to the request and issue the scheduled resource configuration to facilitate the transmission of positioning reference signals and positioning measurements between UEs.

[0096] In some embodiments, as Figure 3 As shown, the method further includes:

[0097] S121: Send an activation instruction; wherein, the activation instruction is used to activate the transmission resource; after the transmission resource is activated, it is used for the first UE and / or the second UE to send an uplink UL sounding reference signal SRS. After the transmission resource is activated, it is used for the first UE and / or the second UE to send an uplink UL sounding reference signal SRS respectively.

[0098] In some embodiments, after the resource configuration is issued, the resources are merely pre-configured, and activation instructions are required for activation when they are used.

[0099] The activation instruction includes but is not limited to: Downlink Control Information (DCI). In other embodiments, the activation instruction may also be: RRC signaling and / or MAC CE.

[0100] In this way, when the base station finds that the UL SRS is not used for uplink positioning or the UE has no uplink data to send, it sends the activation instruction to activate the transmission resource for mutual positioning between UEs, thereby cleverly resolving resource conflicts in the resource reuse process.

[0101] In some embodiments, the resource configuration includes: a first configuration for the first UE to send a UL SRS and / or a second configuration for the second UE to send a UL SRS;

[0102] The issuing of resource configuration according to the phase position location request includes:

[0103] The first configuration and the second configuration are sent to the first UE respectively; and / or the first configuration and the second configuration are sent to the second UE respectively.

[0104] The first UE needs to measure the UL SRS sent by the second UE; and similarly, the second UE needs to measure the SRS sent by the first UE. Therefore, when the base station sends the resource configuration, it will not only send the resource configuration of the UL SRS to the first UE, but also send the resource configuration of the UL SRS sent by the second UE, so as to facilitate the first UE to receive the UL SRS sent by the second UE during the transmission of the UL SRS sent by the second UE. Similarly, when the base station sends the resource configuration, it will not only send the resource configuration of the UL SRS to the second UE, but also send the resource configuration of the UL SRS sent by the first UE, so as to facilitate the second UE to receive the UL SRS sent by the first UE during the transmission of the UL SRS sent by the first UE.

[0105] In some embodiments, when sending down the resource configuration, the base station will carry the identification information of the first UE and the second UE, so as to distinguish the transmission resources for sending UL SRS by the first UE and the second UE respectively in the resource configuration.

[0106] The resource configuration for the first UE and the second UE to send UL SRS can be sent in one signaling or in different signalings. The specific method of sending the resource configuration can be specified by the communication protocol or pre-negotiated by the UE and the base station, and will not be further defined here.

[0107] like Figure 4AAs shown, an embodiment of the present disclosure provides a positioning method between user equipments (UEs), which is applied to a first UE and includes:

[0108] S210: receiving resource configuration;

[0109] S220: Sending UL SRS according to the resource configuration;

[0110] S230: Measure the UL SRS sent by the second UE according to the resource configuration, and generate a first measurement result. The first measurement result is used to determine the relative position between the first UE and the second UE.

[0111] In one embodiment, the first UE may estimate the relative position between itself and the second UE based only on the first measurement result.

[0112] In another embodiment, Figure 4B As shown, the method further includes:

[0113] S240: Receive a second measurement result formed by the second UE measuring the UL SRS sent by the first UE;

[0114] S250: Determine the relative position between the first UE and the second UE according to the first measurement result and the second measurement result.

[0115] In this way, the first UE will receive the second measurement result of the second UE, and thus combine the first measurement result and the second measurement result to determine the relative position between the first UE and the second UE, which is equivalent to determining the relative position between the first UE and the second UE based on a single first measurement result, which will be more accurate and more precise.

[0116] The positioning method is applied to a first UE, and the first UE may be an initialization UE or a target UE for performing relative position positioning between UEs.

[0117] After receiving the resource configuration, the first UE will send UL SRS according to the resource configuration, and will also measure the UL SRS of the second UE according to the resource configuration to form a first measurement result. The second measurement result may include the aforementioned RX-TX time difference, AOA, SRS-SRSQ / SRSP.

[0118] For example, the second UE sends UL SRS according to the resource configuration. Therefore, the first UE can determine the transmission time of the UL SRS sent by the second UE according to the resource configuration, and then calculate the transmission and reception time difference based on the reception time of the UL SRS sent by the second UE.

[0119] For another example, the UL SRS sent by the second UE may carry an accurate transmission time. Thus, the first UE can accurately calculate the transmission and reception time difference based on the reception time of the UL SRS sent by the second UE.

[0120] The measurement of the UL SRS transmitted by the first UE by the second UE is similar to the measurement of the UL SRS transmitted by the second UE by the first UE, and will not be repeated here.

[0121] By combining the first measurement of the second UE with the second measurement result of the first UE, the relative position between the first UE and the second UE can be determined.

[0122] This method is used to measure the phase position between the first UE and the second UE, which can reduce the poor wireless environment caused by directly sending the positioning reference signal for positioning measurement without resource scheduling of the base station, or reduce the interference with cellular mobile communications.

[0123] In some embodiments, the resource configuration includes: a first configuration for the first UE to send a UL SRS and / or a second configuration for the second UE to send a UL SRS;

[0124] The S210 includes: receiving the first configuration and / or the second configuration.

[0125] In an embodiment, the sending of the UL SRS according to the resource configuration includes: sending the UL SRS according to the first configuration.

[0126] The receiving, according to the resource configuration, the UL SRS sent by the second UE to form the first measurement result includes: receiving, according to the second configuration, the UL SRS sent by the second UE to form the first measurement result.

[0127] The resource configuration received by the first UE is a resource configuration in which two UEs send UL SRSs respectively. Therefore, the first UE can perform signal measurement and further positioning according to the resource configuration.

[0128] In some embodiments, the method further comprises:

[0129] Receive activation instructions;

[0130] According to the activation instruction, the transmission resource corresponding to the resource configuration is activated; wherein the UL SRS is transmitted on the activated transmission resource.

[0131] The activation instruction may be: DCI or RRC signaling or MAC CE, so that the UL SRS is transmitted on the activated transmission resource according to the activation instruction, thereby reducing the conflict of UL SRS resource multiplexing.

[0132] In some embodiments, the method further comprises:

[0133] Send a request message to the core network, wherein the request message is used to request measurement of the relative position between the first UE and the second UE, and trigger the core network to send a relative position positioning request to the access network to trigger the access network to send the resource configuration.

[0134] For example, the first UE sends a request message to the core network through transparent transmission of the base station, and specifically sends the request message to the access management function (AMF) or location management function (LMF) of the core network.

[0135] For example, the first UE sends a Positioning Protocol (LPP) message or a NAS message to the core network, where the LPP message or the NAS message carries the request information.

[0136] The request information requests measurement of a phase position between the first UE and the second UE.

[0137] After receiving the request information, the core network will send a relative position positioning request to the base station. The relative position positioning request sent to the base station can directly carry the request message, or extract the information content of the request message and re-encapsulate it into the relative position positioning request.

[0138] like Figure 5A As shown, an embodiment of the present disclosure provides a positioning method between user equipments (UEs), which is applied to a second UE and includes:

[0139] S310: receiving resource configuration;

[0140] S320: Send a UL SRS according to the resource configuration; wherein the UL SRS is used to determine the relative position between the second UE and the first UE.
