Title:
REPORTING ACCURACY OF TIMING AND FREQUENCY SYNCHRONIZATION ASSOCIATED WITH COMMUNICATIONS BETWEEN A NON-TERRESTRIAL NODE AND A TERRESTRIAL NODE
Document Type and Number:
WIPO Patent Application WO/2022/202858
Kind Code:
A1
Abstract:
A method for a user equipment (UE) communicating with a non-terrestrial network (NTN) node is provided. The method transmits one or more parameters to a ground-based base station (BS) communicatively coupled to the NTN node, the one or more parameters transmitted through at least one of uplink control information (UCI), a periodic Channel State Information (CSI) report with CSI information, a Medium Access Control (MAC) Control Element (CE), and a Physical Uplink Control Channel (PUCCH). The one or more parameters are transmitted to the ground-based BS for indicating accuracy of time and frequency synchronization associated with communication between the UE and the NTN node.
