Title:
METHOD AND DEVICE FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/088609
Kind Code:
A1
Abstract:
The present application discloses a method and an apparatus for wireless communication in a communication node. A first node receives first information and transmits second information and third information. The first information is used to indicate a first time window. The second information is used to indicate a second time window. The third information is used to indicate whether the second time window and the first time window are synchronized. When a communication distance between user equipment and a base station is long, especially when NTN communication is involved, pre-compensation can be performed for a timing advance. When NTN user equipment and other user equipment perform D2D networking, the solution provided in the present application that indicates whether pre-compensation has already been performed for a timing advance provides a basis for a selection of a reference synchronization source. When other conditions remain unchanged, an NTN-assisted D2D user, already having pre-compensation performed for a timing advance, is preferentially selected as a reference synchronization source.
