Title:
SIGNAL TRANSMISSION AND FREQUENCY OFFSET ESTIMATION METHODS, COMMUNICATION NETWORK SYSTEM, TERMINAL, ELECTRONIC DEVICE, AND COMPUTER-READABLE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/068789
Kind Code:
A1
Abstract:
The embodiments of the present disclosure relate to the technical field of communications, and provide a signal transmission method. The method can be applied to a communication network system and comprises: transmitting to a terminal a plurality of beams belonging to a cell, each beam among the plurality of beams belonging to a cell being configured with at least one synchronization signal and physical broadcast channel block (SSB), at least two beams among the plurality of beams belonging to a cell forming an overlapping beam group, any two beams in the overlapping beam group having different directions and overlapping, and all SSBs of any two beams being different; receiving performance measurement values of a plurality of SSBs of a plurality of beams in an overlapping beam group transmitted by the terminal, and determining, according to the performance measurement values, one SSB from among the plurality of SSBs; and sending a beam switching request to the terminal, the beam switching request comprising an identification of the SSB. Further provided in the embodiments of the present disclosure are a frequency offset estimation method, a communication network system, a terminal, an electronic device, and a computer-readable medium.
