Abstract: Example neighboring cell relationship configuration methods and apparatus are described. One example method includes: generating a neighboring cell status function identifier by a satellite, where the neighboring cell status function identifier can be used to indicate an inactive state of at least one neighboring cell of a satellite cell. The satellite sends neighboring cell relationship configuration information that includes the neighboring cell status function identifier to a communications device, and the communications device determines a configuration status of a corresponding neighboring cell based on the neighboring cell relationship configuration information.

Abstract: This application provides a sidelink configuration method and apparatus, a device, and a storage medium. In one example, before each sidelink transmission is performed, a terminal device at a transmit end sends SCI to a terminal device at a receive end. In this solution, transmission on information needed for sidelink transmissions is performed by using sidelink RRC, so that the terminal device at the receive end obtains a time-frequency resource configuration of sidelink transmissions, and further obtains a HARQ process identifier of each transmission.

Abstract: This application relates to the field of communications technologies, and discloses a polar code encoding method and apparatus, to improve accuracy of reliability computation and sorting of polar channels. The method is: obtaining a first sequence used to encode K to-be-encoded bits, where the first sequence includes sequence numbers of N polar channels, and the sequence numbers of the N polar channels are arranged in the first sequence based on corresponding reliabilities of the N polar channels, where K is a positive integer, N is a mother code length of a polar code, N is a positive integer that is a power of 2, and K≤N; selecting sequence numbers of K polar channels from the first sequence in descending order of the reliabilities; and placing the to-be-encoded bits based on the selected sequence numbers of the K polar channels, and performing polar code encoding on the to-be-encoded bits.
