Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Supporting various positioning technologies to provide reliable and accurate UE (User Equipment) location has been one of the key areas of the 3GPP (3 rd Generation Partnership Project, third generation partnership project) standard. The 3GPP has completed a first standard Release for UE positioning based on NR (New Radio) signals at Rel-16 (Release-16, release 16).

The problems to be solved by different positioning scenarios are also different. For IIOT (Industrial Internet of Things ) scenario, besides the positioning accuracy requirement, the UE has a high requirement on power consumption overhead. This is because most UEs in the IIOT scenario are powered by a battery, so that the UEs can operate for a long time and continue to locate, and the power consumption overhead of the UEs caused by the locating process is reduced as much as possible.

In the existing Rel-16 positioning method, in order to realize UE positioning, the UE needs to enter an RRC (Radio Resource Control ) connected state, and both power consumption and positioning delay are relatively large. The invention provides an uplink positioning method for UE in a DRX (Discontinuous Reception ) mode in an RRC idle state. The positioning power consumption of the UE can be effectively reduced, and the service time of the equipment is prolonged.

The 3GPP introduced the following RAT (Radio Access Technology ) positioning method based on NR signals in the Rel-16 NR standard:

NR enhanced cell ID positioning method (E-CID)

NR downlink time difference of arrival positioning method (DL-TDOA)

NR uplink time difference of arrival positioning method (UL-TDOA)

NR Multi-cell round trip time positioning method (Multi-RTT)

NR downlink off angle location method (DL-AoD)

NR uplink angular of arrival positioning method (UL-AoA)

All existing positioning methods require the UE to be in an RRC connected state, resulting in a large power consumption overhead of the UE. The UE device in the RRC connected state has an order of magnitude increase in power consumption over the UE device in the RRC idle state.

In IIOT scenario, many UEs are battery powered and the power time for a single UE is expected to be years. The existing RRC connected positioning method is difficult to meet this requirement.

For the positioning scenario of IIOT, existing positioning methods require the UE to be in RRC connected state. The power consumption expense of the UE is large, and the requirement of low-power-consumption work of the UE equipment is difficult to meet.

Therefore, the embodiment of the application provides an uplink positioning method and device, which are used for reducing the positioning power consumption of terminal equipment and increasing the service time of the terminal equipment.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
