9LMF13 location calculation (calculation) message.

In some embodiments, steps 1-1 through 2-3 are not required for the delayed MT-LR for the fig. 3 embodiment described above, as the LMF need only obtain UE capability once.

In some embodiments, the above procedure takes into account worst case scenarios, such as acquiring assistance data and using measurement gaps.

Compared with the common terminal equipment, the RedCAPUE has smaller supported maximum bandwidth and fewer supported antennas. For FR1, for example, the maximum bandwidth supported by the RedCap UE is 20MHz. The requirements of the RedCap UE for power saving (i.e., power consumption saving) are also higher. The RedCap UE is directly positioned, and positioning accuracy is low (mainly because of limited bandwidth of the RedCap UE).

In addition, in the case where the RedCap UE is a wearable type device, the RedCap UE has a high probability of being the same (or similar) location as some normal UE (e.g., an eMBB (Enhanced Mobile Broadband, enhanced mobile bandwidth) UE), i.e., the RedCap UE shares a location with some other UE. And for other UEs, such as an eMBB UE, the supported bandwidth is larger, the positioning precision is higher, and the power consumption ratio required by positioning is lower. That is, the RedCap UE has lower positioning accuracy and is more sensitive to power consumption than the eMBB UE, and positioning results in more power consumption (i.e., the power consumption required for positioning is higher in proportion to the total power).

Fig. 4 is a flowchart illustrating a wireless communication method according to an exemplary embodiment, which is applied to the network architecture shown in fig. 1 for illustration. The method may include the following step 410.

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

In some embodiments, the first terminal device is sensitive to power consumption, or the positioning accuracy of directly positioning the first terminal device is low; in order to save power consumption of the first terminal device or to improve positioning accuracy of the first terminal device, the first terminal device may be caused to send auxiliary information to the network device, so that the network device may perform positioning on the second terminal device sharing a location with the first terminal device. Because the first terminal equipment and the second terminal equipment share the position, after the positioning position of the second terminal equipment is determined, the position of the first terminal equipment can be determined according to the positioning position of the second terminal equipment, so that the indirect positioning of the first terminal equipment is realized. Wherein the second terminal device has a lower sensitivity to power consumption required for positioning than the first terminal device; alternatively, the positioning accuracy of the second terminal device is higher than the positioning accuracy of the first terminal device (e.g., the bandwidth of the second terminal device is greater than the bandwidth of the second terminal device).

In some embodiments, the first terminal device and the second terminal device may be considered to have the same location, and the first terminal device and the second terminal device share the location, that is, the location of the second terminal device is taken as the location of the first terminal device.

In some embodiments, the first terminal device may have one or more second terminal devices with which it shares a location. Under the condition that the auxiliary information is used for indicating the sharing positions of the first terminal equipment and the plurality of second terminal equipment, the network equipment can position the plurality of second terminal equipment to obtain the positioning positions corresponding to the plurality of second terminal equipment respectively, and the network equipment or the first terminal equipment can determine the position of the first terminal equipment according to the positioning positions corresponding to the plurality of second terminal equipment respectively. For example, the average positions of the plurality of second terminal devices are obtained by averaging the positioning positions respectively corresponding to the plurality of second terminal devices, and the average position can be used as the position of the first terminal device. Obviously, the accuracy of the obtained position of the first terminal device can be further improved by determining the position of the first terminal device through the positioning positions of the plurality of second terminal devices.

According to the method and the device, the auxiliary information is sent to the network equipment through the first terminal equipment, and the shared position of the first terminal equipment and the second terminal equipment is indicated in the auxiliary information, so that the position of the first terminal equipment can be determined according to the positioning position of the second terminal equipment, the first terminal equipment is prevented from being directly positioned, and the power consumption of the first terminal equipment in the positioning process is saved.

Optionally, the auxiliary information includes: and the identity of the second terminal device.

Optionally, the identification of the second terminal device comprises at least one of: IMSI, 5G globally unique temporary identity, 5G temporary mobile station identity, 5G truncated temporary mobile subscriber identity.

In some embodiments, the identifier of the second terminal device may be determined uniquely to identify the second terminal device, that is, the identifier of each second terminal device is different, so as to avoid a positioning error caused by the same identifier, ensure the accuracy of positioning the second terminal device, and further ensure 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: eMBBUE, iioT (Industrial Internet of Things ) UE, non-RedCap UE (non-low capability terminal). Optionally, the first terminal device is a RedCap UE.

In some embodiments, the type of the second terminal device may also be any of the following: terminal devices such as smart phones, tablet computers, PCs (Personal Computer, personal computers), smart televisions, smart robots, and vehicle-mounted computers.

Illustratively, the first terminal device is a smart watch and the second terminal device is a smart phone. Because the proportion of the consumed electric quantity in the positioning process of the smart watch in the total electric quantity of the smart watch is obviously larger than the proportion of the consumed electric quantity of the smart phone in the positioning process in the total electric quantity of the smart phone, the smart phone and the smart watch are usually together for a user, and the distance is relatively short. Therefore, the intelligent watch can participate in the actual positioning process by reporting the identification of the intelligent mobile phone, and the position of the intelligent watch can be basically determined after the network equipment or the intelligent watch acquires the positioning position of the intelligent mobile phone, for example, the positioning position of the intelligent mobile phone is determined as the position of the intelligent watch.

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

Optionally, the auxiliary information includes: a first information element for indicating a shared location.

In some embodiments, the network device that receives the information can determine the information as auxiliary information through a first information element in the information for indicating the shared location; that is, if the assistance information is carried in another type of message (e.g., RRC message), the network device cannot identify the assistance information (e.g., does not know the use of the identifier of the second terminal device in the message), a first information element for indicating the shared location needs to be added to the assistance information, so that the network device can identify the assistance information according to the first information element (e.g., identifies that the identifier of the second terminal device in the message is used to obtain the location of the second terminal device).

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

In some embodiments, the locations of the first and second terminal devices are not necessarily identical, but may be separated by some distance, i.e. have a certain location error. The second information element can indicate the position error range between the first terminal device and the second terminal device, so that the accuracy of the obtained position of the first terminal device is improved.

In some embodiments, the position error range includes: horizontal error range, 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 meter, meaning that the horizontal distance between the first terminal device and the second terminal device does not exceed 0.1 meter. By combining the horizontal error range and the vertical error range, the accuracy of the obtained position of the first terminal device can be further improved.
