Abstract

The invention provides an information processing method and device, a terminal and network side equipment, and the information processing method comprises the steps: transmitting first information related to receiving and transmitting timing delay or timing error to the terminal and / or second network side equipment; wherein the transceiving timing delay or the timing error refers to a signal transmission delay or a delay error between an antenna unit of the terminal and a baseband unit of the terminal, or a signal transmission delay or a delay error between an antenna unit of a base station and the baseband unit of the base station; the first network side equipment is a base station, and the second network side equipment is a positioning server; or, the first network side equipment is a positioning server, and the second network side equipment is a base station; the first information is internal time delay information or time delay error information of the terminal or the base station. The scheme can solve the problem in the prior art that the positioning precision is influenced because the receiving and transmitting timing error cannot be obtained.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to an information processing method, apparatus, terminal, and network side equipment. Background technique [0002] Among the existing positioning methods, the Multi-RTT (multiple round-trip time) positioning method is an important positioning method. The working principle of the Multi-RTT positioning method is that the UE (terminal) reports the obtained UE sending and receiving time difference to the LMF (Location management function unit), each TRP (transmit and receive point) also provides the obtained gNB (base station) transmit and receive time difference to the LMF, and the LMF obtains the distance between the UE and each TRP by using the UE transmit and receive time difference and the gNB transmit and receive time difference. Then add other known information (such as the geographic coordinates of the TRP) to calculate the location of the UE. [0003] ...
