[0059] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system 100 shown in FIG1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function.

The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone.

The present application does not limit the protocol type.

[0067] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0068] To facilitate a better understanding of the embodiments of the present application, the sidelink positioning related to the present application is explained.

[0069] As a supplement to the traditional 5G positioning that relies on terminals and gNB (TRP), sidelink positioning additionally utilizes the reference signal measurement results between terminals to complete positioning. For sidelink positioning, the reference signal should be sent and measured in the sidelink specified frequency band. The measurement results should reflect the positioning reference variables that have actual physical meaning in space, such as the relative distance and relative angle between terminals. After triggering sidelink positioning, the terminal with positioning requirements first needs to find a suitable anchor device through network allocation or its own measurement of surrounding signals, and then obtain the positioning measurement results by measuring the reference signal sent by the anchor device and / or the anchor device measuring the reference signal sent by the terminal with positioning requirements, and derive the positioning results.

[0070] In some embodiments, the sidelink positioning process in an out-of-coverage communication scenario is shown in Figures 2 and 3, where Figure 2 is a positioning process based on a UE with positioning requirements sending a sidelink positioning reference signal, and Figure 3 is a positioning process based on an anchor UE sending a sidelink positioning reference signal.

[0071] In FIG. 2 or FIG. 3 , if the terminal only obtains the configuration information of the reference signal of the anchor device from the Provide Location Assistance Data (ProvideLocationAssistanceData) signaling but does not have the location information of the anchor device, the terminal cannot complete positioning.

[0072] It should be noted that for sidelink positioning in out-of-coverage scenarios, the location information of the anchor device is unknown to the components controlled by the various operators of the 5G network, and the location information of the anchor device cannot be sent to the terminal in real time.

[0073] In a partial coverage positioning scenario, at least one anchor device is directly connected to the network, while the other anchor devices are located outside the 5G network. In this case, if the positioning operation is performed on the network side, the location information of the other anchor devices must also be sent to the network (routing through the path of anchor device-terminal-anchor device directly connected to the network-network or anchor device-terminal-network).

[0074] For in-coverage positioning scenarios, the location of the anchor device can be transmitted through direct signaling between the anchor device and the terminal, or through an anchor device-network-terminal route to assist in terminal positioning.

[0075] However, in the above solution, the location information of the anchor device cannot be obtained by the terminal or the network, and side positioning cannot be completed.

[0076] Based on the above problems, the present application proposes a side positioning solution, whereby a terminal device or a network device can determine the location information of the terminal device based on the location information of M anchor devices, thereby achieving side positioning.

[0077] The technical solution of this application is described in detail below through specific embodiments.

[0078] FIG4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG4 , the wireless communication method 200 may include at least part of the following contents:

[0079] S210, the terminal device obtains location information of M anchor devices; wherein the location information of the M anchor devices is used to determine the location information of the terminal device, and M is a positive integer.

[0080] In the embodiment of the present application, the terminal device is a terminal with positioning requirements.

[0081] In the embodiment of the present application, the anchor device may be a device for assisting terminal positioning, which can send a reference signal on a sidelink or measure a received reference signal. The anchor device and the terminal device may communicate via a PC5 interface.

[0082] In the embodiments of the present application, the "anchor device" may also be referred to as an "anchor terminal" or a "roadside unit (RSU)" or an "other terminal" or a "relay terminal", which is not limited in the present application.

[0083] In some embodiments, the M anchor point devices are located in an out-of-coverage communication scenario, or in a partial coverage communication scenario or an in-coverage communication scenario.

[0084] In some embodiments, the terminal device can determine the location information of the terminal device based on the location information of the M anchor devices; or, the terminal device can report the location information of the M anchor devices to the network device, so that the network device can determine the location information of the terminal device based on the location information of the M anchor devices.

[0085] In some embodiments, the M anchor point devices may be selected or determined by the terminal device. In other embodiments, the M anchor point devices may be selected or determined by the network device and indicated to the terminal device.

[0086] In some embodiments, in the above S210, the terminal device obtains the location information of the corresponding anchor devices from the M anchor devices. Specifically, for example, when the locations of the M anchor devices are not fixed, the terminal device obtains the location information of the corresponding anchor devices from the M anchor devices.

[0087] In some embodiments, the terminal device receives first information, which includes the location information of the corresponding anchor device. Optionally, the first information is carried via broadcast or dedicated signaling. This ensures that the terminal device can obtain the location information of the anchor device immediately. For example, anchor device 1 sends first information, which includes the location information of anchor device 1.

[0088] In some embodiments, the location information included in the first information is location information periodically sent by the corresponding anchor device, or the location information included in the first information is location information sent once by the corresponding anchor device.

[0089] For example, the location information included in the first information is the location information of the corresponding anchor device at a past time T, where time T is a sending period.

[0090] In some embodiments, the first information further includes a sidelink positioning reference signal (S-PRS) measurement result of the corresponding anchor device.

[0091] In some embodiments, before receiving the first information, the terminal device sends a second information requesting the anchor device to provide its location information. Optionally, the second information is carried via broadcast or dedicated signaling, thereby ensuring that the anchor device can obtain the second information immediately.

[0092] In some embodiments, when the location information included in the first information is location information periodically sent by the corresponding anchor device, the second information includes periodic configuration parameters.

[0093] In some embodiments, in the above S210, the terminal device obtains the location information of the M anchor devices from the network device. Optionally, the locations of the M anchor devices are fixed. For example, the M anchor devices are roadside units.

[0094] In some embodiments, the terminal device determines the location information of the terminal device based on the location information of the M anchor devices. Specifically, for example, in a UE-based positioning result calculation mode, the terminal device receives the location information of the anchor device and performs positioning.

[0095] In some embodiments, the terminal device determines the location information of the terminal device based on the location information of the M anchor point devices and the S-PRS measurement results of the M anchor point devices.

[0096] In some embodiments, the terminal device reports the third information, or the terminal device reports the third information through another terminal device;

[0097] The third information includes location information of the M anchor devices.

[0098] For example, in a mode where the positioning result is calculated based on the network, such as the Location Management Function (LMF) entity, the terminal device receives and forwards the location information of the anchor device to the base station (via the Uu interface) or the terminal directly connected to the base station (via sidelink), and then sends it to the base station, and finally sends it to the core network element (such as the LMF entity) by the base station.

[0099] In some embodiments, the third information further includes S-PRS measurement results of the M anchor devices.

[0100] In some embodiments, the S-PRS measurement results of the M anchor devices are respectively obtained from corresponding anchor devices, or the S-PRS measurement results of the M anchor devices are obtained by measurement by the terminal device.

[0101] In some embodiments, the terminal device determines the M anchor devices from the plurality of anchor devices according to location availability indication information of the plurality of anchor devices;

[0102] Among them, the location availability indication information is used to indicate at least one of the following: whether the corresponding anchor device has its location information, whether the corresponding anchor device allows the transmission of its location information, the credibility of the location information of the corresponding anchor device, and whether the location information of the corresponding anchor device meets the positioning integrity requirements.

[0103] Specifically, the multiple anchor point devices may be candidate anchor point devices or candidate anchor point terminals, the multiple anchor point devices may be selected or determined by the terminal device, or the multiple anchor point devices may be selected or determined by the network device and indicated to the terminal device.

[0104] In some embodiments, the anchor device can evaluate the credibility of its location information, or other devices (such as terminal devices or network devices) can evaluate the credibility of the anchor device's location information. For example, the credibility of location information when there is building obstruction is lower than the credibility of location information when there is no building obstruction, the credibility of indoor location information is lower than the credibility of outdoor location information, and the credibility of location information when stationary or moving at low speed is lower than the credibility of location information when moving at high speed.

[0105] In some embodiments, the terminal device determines the anchor devices among the multiple anchor devices that can be used for positioning the terminal device based on location availability indication information of multiple anchor devices, and the terminal device determines the anchor devices that can be used for positioning the terminal device as the M anchor devices.

[0106] For example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information, then the terminal device determines that anchor device 1 and anchor device 3 can be used for the positioning of the terminal device.

[0107] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information and is not allowed to transmit its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information and is allowed to transmit its location information, then the terminal device determines that anchor device 3 can be used for the positioning of the terminal device.

[0108] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that the credibility of the location information of anchor device 1 is 1, the location availability indication information of anchor device 2 indicates that the credibility of the location information of anchor device 2 is 2, and the location availability indication information of anchor device 3 indicates that the credibility of the location information of anchor device 3 is 3. The lower the credibility value, the higher the credibility. The terminal device determines that anchor device 1 can be used for the positioning of the terminal device, or the terminal device determines that anchor device 1 and anchor device 2 can be used for the positioning of the terminal device.

[0109] In some embodiments, the terminal device ranks the plurality of anchor devices according to their location availability indication information, and the terminal device determines the M anchor devices according to the priority ranking of the plurality of anchor devices.

[0110] For example, the multiple anchor devices include anchor device 1, anchor device 2, and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information. Then, anchor device 1 and anchor device 3 have the same priority, and the priority of anchor device 1 and anchor device 3 is higher than the priority of anchor device 2. The terminal device can determine that anchor device 1 and anchor device 3 can be used for positioning of the terminal device.

[0111] For another example, multiple anchor devices include anchor device 1, anchor device 2, and anchor device 3, where the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information and is not allowed to transmit its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information and is allowed to transmit its location information. Then, the priorities of the three anchor devices are ranked from high to low as: anchor device 3, anchor device 1, anchor device 2, or anchor device 1 and anchor device 2 have the same priority, and the priorities of anchor device 1 and anchor device 2 are lower than the priority of anchor device 3. Then, the terminal device determines that anchor device 3 can be used for positioning the terminal device.

[0112] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that the credibility of the location information of anchor device 1 is 1, the location availability indication information of anchor device 2 indicates that the credibility of the location information of anchor device 2 is 2, and the location availability indication information of anchor device 3 indicates that the credibility of the location information of anchor device 3 is 3. The lower the credibility value, the higher the credibility. The priority of the three anchor devices is ranked from high to low as follows: anchor device 1, anchor device 2, anchor device 3. The terminal device determines that anchor device 1 can be used for the positioning of the terminal device, or the terminal device determines that anchor device 1 and anchor device 2 can be used for the positioning of the terminal device.

[0113] In some embodiments, the location availability indication information is sent by the corresponding anchor device via broadcast or dedicated signaling, thereby ensuring that the terminal device can obtain the location availability indication information in the first place.

[0114] In some embodiments, the terminal device reports fourth information;

[0115] The fourth information includes at least one of the following: location availability indication information of N anchor devices among the multiple anchor devices, identification information of anchor devices among the multiple anchor devices that can be used for positioning the terminal device, and priority sorting information of the multiple anchor devices;

[0116] Wherein, N is a positive integer, and N≥M.

[0117] It should be noted that the location availability indication information may not be known at the LMF, which may affect the LMF's position solution. Therefore, the terminal device may also send the location availability indication information of certain anchor devices, priority ranking information, and identification information of the anchor devices that can be used for terminal device positioning to the LMF. Optionally, the location availability indication information of certain anchor devices may be sent according to the request sent by the LMF.

It should be understood that the network side embodiment and the terminal side embodiment correspond to each other, and similar descriptions can refer to the terminal side embodiment.

[0123] FIG5 is a schematic flowchart of a wireless communication method 300 according to an embodiment of the present application. As shown in FIG5 , the wireless communication method 300 may include at least part of the following contents:

[0124] S310, the network device obtains location information of M anchor devices; wherein the location information of the M anchor devices is used to determine the location information of the terminal device, and M is a positive integer.

[0125] In the embodiment of the present application, the terminal device is a terminal with positioning requirements.

[0126] In the embodiment of the present application, the anchor device may be a device for assisting terminal positioning, which can send a reference signal on a sidelink or measure a received reference signal. The anchor device and the terminal device may communicate via a PC5 interface.

[0127] In the embodiments of the present application, the "anchor device" may also be referred to as an "anchor terminal" or a "roadside unit (RSU)" or an "other terminal" or a "relay terminal", which is not limited in the present application.

[0128] In some embodiments, the network device includes at least one of the following: an access network device, a LMF entity, and an access and mobility management function (AMF) entity.

[0129] In some embodiments, the M anchor point devices are located in an out-of-coverage communication scenario, or in a partial coverage communication scenario or an in-coverage communication scenario.

[0130] In some embodiments, the M anchor point devices may be selected or determined by the terminal device. In other embodiments, the M anchor point devices may be selected or determined by the network device and indicated to the terminal device.

[0131] In some embodiments, in the above S310, the network device receives third information, wherein the third information includes the location information of the M anchor devices. Optionally, the third information is sent by the terminal device, or the third information is sent by the terminal device through another terminal device.

[0132] For example, in a mode where positioning results are calculated based on a network, such as an LMF entity, the terminal device receives and forwards the location information of the anchor device to the base station (via the Uu interface) or the terminal directly connected to the base station (via sidelink), which is then sent by the terminal to the base station, and finally sent by the base station to the core network element (such as the LMF entity).

[0133] In some embodiments, the location information of the M anchor devices is obtained from the corresponding anchor devices. Optionally, the locations of the M anchor devices are fixed. For example, the M anchor devices are roadside units.

[0134] For example, the anchor device sends its location information periodically, or the anchor device sends its location information once.

[0135] In some embodiments, the third information further includes S-PRS measurement results of the M anchor devices.

[0136] In some embodiments, the S-PRS measurement results of the M anchor devices are respectively obtained from corresponding anchor devices, or the S-PRS measurement results of the M anchor devices are obtained by measurement by the terminal device.

[0137] In some embodiments, in the above S310, the network device obtains the location information of the M anchor devices from a local location. Optionally, the locations of the M anchor devices are fixed. For example, the M anchor devices are roadside units.

[0138] In some embodiments, the network device determines the location information of the terminal device based on the location information of the M anchor devices.

[0139] In some embodiments, the network device determines the location information of the terminal device based on the location information of the M anchor point devices and the S-PRS measurement results of the M anchor point devices.

[0140] In some embodiments, the network device determines the M anchor devices from the plurality of anchor devices according to location availability indication information of the plurality of anchor devices;

[0141] Among them, the location availability indication information is used to indicate at least one of the following: whether the corresponding anchor device has its location information, whether the corresponding anchor device allows the transmission of its location information, the credibility of the location information of the corresponding anchor device, and whether the location information of the corresponding anchor device meets the positioning integrity requirements.

[0142] In some embodiments, the anchor device can evaluate the credibility of its location information, or other devices (such as terminal devices or network devices) can evaluate the credibility of the anchor device's location information. For example, the credibility of location information when there is building obstruction is lower than the credibility of location information when there is no building obstruction, the credibility of indoor location information is lower than the credibility of outdoor location information, and the credibility of location information when stationary or moving at low speed is lower than the credibility of location information when moving at high speed.

[0143] In some embodiments, the network device determines the anchor devices among the multiple anchor devices that can be used for positioning the terminal device based on location availability indication information of the multiple anchor devices, and the network device determines the anchor devices that can be used for positioning the terminal device as the M anchor devices.

[0144] For example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information, then the network device determines that anchor device 1 and anchor device 3 can be used for positioning the terminal device.

[0145] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information and is not allowed to transmit its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information and is allowed to transmit its location information, then the network device determines that anchor device 3 can be used for positioning the terminal device.

[0146] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that the credibility of the location information of anchor device 1 is 1, the location availability indication information of anchor device 2 indicates that the credibility of the location information of anchor device 2 is 2, and the location availability indication information of anchor device 3 indicates that the credibility of the location information of anchor device 3 is 3. The lower the credibility value, the higher the credibility. The network device determines that anchor device 1 can be used for positioning the terminal device, or the network device determines that anchor device 1 and anchor device 2 can be used for positioning the terminal device.

[0147] In some embodiments, the network device ranks the priorities of the plurality of anchor devices according to the location availability indication information of the plurality of anchor devices, and the network device determines the M anchor devices according to the priority ranking of the plurality of anchor devices.

[0148] For example, the multiple anchor devices include anchor device 1, anchor device 2, and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information. Then, anchor device 1 and anchor device 3 have the same priority, and the priority of anchor device 1 and anchor device 3 is higher than the priority of anchor device 2. The network device can determine that anchor device 1 and anchor device 3 can be used for positioning the terminal device.

[0149] For another example, the multiple anchor devices include anchor device 1, anchor device 2, and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that anchor device 1 has its location information and is not allowed to transmit its location information, the location availability indication information of anchor device 2 indicates that anchor device 2 does not have its location information, and the location availability indication information of anchor device 3 indicates that anchor device 3 has its location information and is allowed to transmit its location information. Then, the priorities of the three anchor devices are ranked from high to low as: anchor device 3, anchor device 1, anchor device 2, or anchor device 1 and anchor device 2 have the same priority, and the priorities of anchor device 1 and anchor device 2 are lower than the priority of anchor device 3. Then, the network device determines that anchor device 3 can be used for positioning the terminal device.

[0150] For another example, multiple anchor devices include anchor device 1, anchor device 2 and anchor device 3, wherein the location availability indication information of anchor device 1 indicates that the credibility of the location information of anchor device 1 is 1, the location availability indication information of anchor device 2 indicates that the credibility of the location information of anchor device 2 is 2, and the location availability indication information of anchor device 3 indicates that the credibility of the location information of anchor device 3 is 3. The lower the credibility value, the higher the credibility. The priority of the three anchor devices is ranked from high to low as follows: anchor device 1, anchor device 2, anchor device 3. The network device determines that anchor device 1 can be used for positioning the terminal device, or the network device determines that anchor device 1 and anchor device 2 can be used for positioning the terminal device.

[0151] In some embodiments, the location availability indication information of the multiple anchor point devices is sent by the terminal device, or the location availability indication information of the multiple anchor point devices is sent by the terminal device through other terminal devices, or the location availability indication information of the multiple anchor point devices is sent separately by each anchor point device.

[0152] In some embodiments, the network device receives fourth information, and the network device determines the M anchor devices based on the fourth information;

[0153] The fourth information includes at least one of the following: location availability indication information of N anchor devices among the multiple anchor devices, identification information of the anchor devices among the multiple anchor devices that can be used for positioning the terminal device, and priority sorting information of the multiple anchor devices;

[0154] The location availability indication information is used to indicate at least one of the following: whether the corresponding anchor device has its location information, whether the corresponding anchor device allows its location information to be transmitted, the credibility of the location information of the corresponding anchor device, and whether the location information of the corresponding anchor device meets the positioning integrity requirement;

[0155] Wherein, N is a positive integer and N≥M;.

[0156] It should be noted that the location availability indication information may not be known at the LMF, which may affect the LMF's position solution. Therefore, the terminal device may also send the location availability indication information of certain anchor devices, priority ranking information, and identification information of the anchor devices that can be used for terminal device positioning to the LMF. Optionally, the location availability indication information of certain anchor devices may be sent according to the request sent by the LMF.

[0157] Optionally, the fourth information is carried by one of the following: RRC, UCI, MAC CE.

[0158] In some embodiments, before receiving the fourth information, the network device sends fifth information, where the fifth information is used to request the location availability indication information. Optionally, the fifth information is also used to indicate the N anchor devices.

[0159] Optionally, the fifth information is carried by one of the following: RRC, DCI, MAC CE.

[0160] Therefore, in an embodiment of the present application, the positioning calculation unit (terminal device and / or network device) can determine the location information of the terminal device based on the location information of M anchor devices, thereby realizing side positioning. Furthermore, the positioning calculation unit (terminal device and / or network device) can periodically or once obtain the location information of the anchor device to infer the location information of the located terminal. Furthermore, the positioning calculation unit (terminal device and / or network device) can also sort the priority of the anchor devices or determine whether the anchor device is suitable for positioning based on the location availability indication information sent by the anchor device.

[0170] In some embodiments, the location information included in the first information is location information periodically sent by the anchor device, or the location information included in the first information is location information sent once by the anchor device.

[0171] For example, the anchor device sends its location information periodically, or the anchor device sends its location information once.

[0172] In some embodiments, the first information further includes an S-PRS measurement result of the anchor device.

[0173] In some embodiments, the first information is carried via broadcast or dedicated signaling, thereby ensuring that the terminal device can obtain the first information in a timely manner.

[0174] In some embodiments, before sending the first information, the anchor device receives second information for requesting the anchor device to provide its location information. For example, the anchor device receives the second information sent by the terminal device, or the anchor device receives the second information sent by the network device.
