In some embodiments, for delayed MT-LR, steps 1-1 to 2-3 are not required for the above-described Figure 3 embodiment because the LMF only needs to obtain the UE capabilities once.

In some embodiments, the above process considers worst-case scenarios, such as obtaining auxiliary data and using measurement gaps.

Compared with ordinary terminal equipment, RedCapUE supports a smaller maximum bandwidth and fewer antennas. For example, for FR1, the maximum bandwidth supported by RedCap UE is 20MHz. RedCap UE also has higher requirements for power saving (that is, saving power consumption). Direct positioning of RedCap UE has low positioning accuracy (mainly due to the limited bandwidth of RedCap UE).

In addition, when the RedCap UE is a wearable device, there is a high probability that the RedCap UE is in the same (or close) location as an ordinary UE (such as an eMBB (Enhanced Mobile Broadband, enhanced mobile bandwidth) UE), that is, the RedCap UE Share location with some other UE. For other UEs, such as eMBB UE, they support larger bandwidth, higher positioning accuracy, and lower power consumption required for positioning. That is to say, compared with eMBB UE, RedCap UE has lower positioning accuracy, and RedCap UE is more sensitive to power consumption, and positioning will result in more power consumption (that is, the power consumption required for positioning accounts for a higher proportion of the total power).

FIG. 4 is a flow chart of a wireless communication method according to an exemplary embodiment. This embodiment illustrates an example in which the wireless communication method is applied to the network architecture shown in FIG. 1 . The method may include the following step 410.

In step 410, the first terminal device sends auxiliary information to the network device, where the auxiliary information is used to indicate that the first terminal device and at least one second terminal device share a location.

In some embodiments, the first terminal device is more sensitive to power consumption, or the positioning accuracy of directly positioning the first terminal device is low; in order to save the power consumption of the first terminal device, or to improve the power consumption of the first terminal device, The positioning accuracy enables the first terminal device to send auxiliary information to the network device, so that the network device can locate the second terminal device that shares a location with the first terminal device. Since the first terminal device and the second terminal device share a location, after the positioning position of the second terminal device is determined, the position of the first terminal device can be determined based on the positioning position of the second terminal device, thereby realizing the positioning of the first terminal device. indirect positioning. Among them, the second terminal device is less sensitive to the power consumption required for positioning than the first terminal device; or, the positioning accuracy of the second terminal device is higher than the positioning accuracy of the first terminal device (such as the bandwidth ratio of the second terminal device The bandwidth of the second terminal device is large).

In some embodiments, it can be considered that the first terminal device and the second terminal device are in the same position, and the first terminal device and the second terminal device share the position, which means that the positioning position of the second terminal device is used as the position of the first terminal device. .

In some embodiments, a first terminal device may have one or more second terminal devices with which it shares a location. In the case where the auxiliary information is used to indicate that the first terminal device and multiple second terminal devices share a location, the network device may position the multiple second terminal devices to obtain positioning locations corresponding to the multiple second terminal devices, The network device or the first terminal device may determine the location of the first terminal device based on the corresponding positioning positions of the plurality of second terminal devices. For example, the positioning positions corresponding to the plurality of second terminal devices are averaged to obtain the average position of the plurality of second terminal devices, and the average position can be used as the position of the first terminal device. Obviously, by determining the position of the first terminal device through the positioning positions of multiple second terminal devices, the accuracy of the obtained position of the first terminal device can be further improved.

The present disclosure uses the first terminal device to send auxiliary information to the network device. Since the auxiliary information indicates that the first terminal device and the second terminal device share a location, the location of the first terminal device can be determined based on the positioning location of the second terminal device, which avoids In order to directly position the first terminal device, the power consumption required by the first terminal device during the positioning process is saved.

Optionally, the identity of the second terminal device includes at least one of the following: IMSI, 5G globally unique temporary identity, 5G temporary mobile station identity, and 5G truncated temporary mobile user identity.

In some embodiments, the identifier of the second terminal device can uniquely identify the second terminal device, that is, the identifier of each second terminal device is different, thereby avoiding positioning errors caused by the same identifier and ensuring that the second terminal device is securely identified. The accuracy of the positioning of the terminal device ensures the accuracy of the obtained position of the first terminal device.

In some embodiments, the type of the second terminal device may be any of the following: eMBB UE, IioT (Industrial Internet of Things, Industrial Internet of Things) UE, non-RedCap UE (non-low-capability terminal). Optionally, the first terminal device is RedCap UE.

In some embodiments, the type of the second terminal device may also be any of the following: terminal devices such as smartphones, tablets, PCs (Personal Computers), smart TVs, smart robots, and vehicle-mounted computers.

For example, the first terminal device is a smart watch, and the second terminal device is a smartphone. Since the proportion of power consumed by smart watches in the positioning process to the total power of smart watches is significantly greater than the proportion of power consumed by smartphones in the positioning process to the total power of smart phones, for users, smartphones Smartwatches and smartwatches are usually together, and the distance is generally relatively close. Therefore, the smart watch can allow the smart phone to participate in the actual positioning process by reporting the smart phone's identification. After the network device or smart watch obtains the smart phone's positioning position, the smart watch's position can basically be determined. For example, if the smart watch is The positioning position of the mobile phone is determined as the position of the smart watch.

Of course, the second terminal device may also be of other types, which is not specifically limited in this disclosure.

In some embodiments, the network device that receives the information can determine that the information is auxiliary information through the first information element in the information used to indicate the shared location; that is, if the auxiliary information is carried in other types of messages ( If the network device cannot recognize the auxiliary information (for example, it does not know the purpose of the identifier of the second terminal device in the message), it needs to add a first information element indicating the shared location to the auxiliary information. The network device is enabled to identify the auxiliary information according to the first information element (for example, identifying that the identifier of the second terminal device in the message is used to obtain the positioning position of the second terminal device).

In some embodiments, if a relevant protocol is pre-established between the first terminal device and the network device, the auxiliary message may not include the first information element, and the network device can also identify the auxiliary information sent by the first terminal device.

Optionally, the auxiliary information includes: a second information element indicating a position error range.

In some embodiments, the positions of the first terminal device and the second terminal device are not necessarily exactly the same, but may be separated by a certain distance, that is, there is a certain position error. Through the second information element, the position error range between the first terminal device and the second terminal device can be indicated, thereby improving the accuracy of the obtained position of the first terminal device.

In some embodiments, the position error range includes: a horizontal error range and a vertical error range. For example, the horizontal error range of the positions of the first terminal device and the second terminal device does not exceed 0.1 meters, which means that the horizontal distance between the first terminal device and the second terminal device does not exceed 0.1 meters. Combining the horizontal error range and the vertical error range can further improve the accuracy of the obtained position of the first terminal device.

Optionally, the network device is an LMF, and the first terminal device sends the auxiliary information to the LMF.

In some embodiments, the LMF positions at least one second terminal device respectively (or the LMF obtains the positioning position of the second terminal device) based on the relevant information of the at least one second terminal device in the auxiliary information. Afterwards, the network device may determine the position of the first terminal device based on the positioning position of at least one second terminal device, and send the position of the first terminal device to the first terminal device; or, the network device may send the position of the at least one second terminal device to the first terminal device. The positioning position is sent to the first terminal device, and the first terminal device determines its own position based on the positioning position of at least one second terminal device.
