Problems solved by technology

[0004] However, when the positioning measurement is measured when the propagation path is in the NLOS state, the LMF network element still believes that the positioning measurement is measured when the propagation path is in the LOS state, and calculates the The position of the terminal device will affect the positioning accuracy, resulting in low positioning accuracy

Embodiment Construction

[0292] Embodiments of the present application provide a communication method, a positioning device, and a terminal device, so as to improve positioning accuracy.

[0293] see Figure 1A , Figure 1A It is a schematic diagram of the architecture of the communication system in the embodiment of the present application. The communication system includes a terminal device 101, a next generation Node B (next Generation Node B, gNB) 102, a next generation evolved Node B (nextgeneration evolved Node B, ng-eNB) 103, an access and mobility management function (access and mobilitymanagement function (AMF) 104 and LMF network element 105.

[0294] Among them, the terminal equipment communicates with the serving base station (such as Figure 1A gNB or ng-eNB) in the communication. The ng-eNB is a base station in a Long Term Evolution (Long Term Evolution, LTE) communication system, and the gNB is a base station in an NR communication system. In the communication system, the base station...

Abstract

The embodiment of the invention discloses a communication method. The method comprises the steps that positioning equipment receives a position information providing message sent by terminal equipment, wherein the position information providing message carries a first parameter, the first parameter is used for indicating a first propagation condition corresponding to a first positioning measurement quantity of the terminal equipment, the first propagation condition is that a first signal propagation path is in a line-of-sight (LOS) state, or the first signal propagation path is in a non-line-of-sight (NLOS) state, and the first signal propagation path is a propagation path for an access network equipment to send a first reference signal to the terminal equipment; and the positioning equipment determines a first propagation condition corresponding to the first positioning measurement quantity according to the first parameter. As the accuracy of the positioning measurement quantity measured in the NLOS state is low, the positioning equipment can exclude the positioning measurement quantity in the NLOS state during positioning calculation, and only the positioning measurement quantity in the LOS state is selected for positioning calculation, so that the positioning precision is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, a positioning device and a terminal device. Background technique [0002] In New Radio (NR) positioning, it is required to position a terminal device with high precision. In addition to requiring the accuracy of the positioning measurement, it is also required that the positioning measurement comes from a direct line of sight, which is also called a line of sight (LOS). The direct path means that the wireless signal reaches the receiving end directly from the transmitting end, and if the wireless signal encounters an obstacle, reflects or scatters and then reaches the receiving end, it is called a non-direct path, also known as non-line-of-sight (non-line-of-sight) , NLOS). [0003] At present, among the uplink and downlink positioning technologies, the downlink positioning technology is taken as an example for description here. The ...
