Abstract: A channel encoding method and apparatus. The method includes: obtaining A to-be-encoded information bits; mapping the A to-be-encoded information bits and L CRC bits to a first bit sequence based on an interleaving sequence, where the L CRC bits are obtained based on the A to-be-encoded information bits and a CRC polynomial, the interleaving sequence is obtained from a prestored interleaving sequence table or is obtained based on a maximum-length interleaving sequence, A+L is less than or equal to Kmax, and Kmax is a length of the maximum-length interleaving sequence; and encoding the first bit sequence. In this way, not only an encoding delay can be reduced, but also decoding has an early stop capability, so that decoding can end in advance, thereby reducing a decoding delay.

Abstract: A satellite communication method and a network device are disclosed. A first network device learns of traffics of a plurality of satellite communications link or air interface resources allocated to a plurality of satellite base stations. The first network device sends identification information to a second network device, where the identification information indicates that a traffic of a satellite communications link reaches a specified threshold, or that an air interface resource allocated by a ground station to a satellite base station reaches a specified threshold. The second network device receives an identifier message, determines a to-be-linked satellite base station that has an idle resource, and sends, to the to-be-linked satellite base station, a second message including information about a generated beam of the to-be-linked satellite base station.

Abstract: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.
