Title:
COMMUNICATION METHOD AND APPARATUS, CELL MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/062599
Kind Code:
A1
Abstract:
The present application provides a communication method and apparatus. The method may comprise: a terminal device receiving time information corresponding to at least one frequency point on satellite ephemeris of a satellite, and the terminal device determining, according to the satellite ephemeris, information such as a trajectory of the satellite; the terminal device determining, according to a certain time, such as the current time, and time information corresponding to at least one frequency point, frequency point information to be measured currently, and also determining frequency point information to be measured when the terminal device reselects another cell. The method can reduce signaling overheads caused by a terminal device requesting a system message many times, thereby helping the terminal device to save power.
