Title:
METHOD FOR DETERMINING TIME ADVANCE (TA), AND NETWORK DEVICE AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2021/254147
Kind Code:
A1
Abstract:
Provided are a method for determining a time advance (TA), and a communication apparatus. A terminal device in a non-connected state acquires time advance indication information, such as a wireless network temporary identifier of a time advance command, a time advance command sending period, a time advance command duration and a time advance command receiving window, by means of a radio resource control release (RRC Release) message or a paging message. In this way, the terminal device in the non-connected state may determine a TA value on the basis of the time advance indication information. The technical solution of the present application may be further applied to a positioning scenario, such that a terminal device may perform positioning in a non-connected state, and the power consumption of the terminal device is reduced compared with existing solutions.
