Abstract: Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.

Abstract: The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.

Abstract: A method, a device, and a system for triggering a scheduling request (SR) to meet quality of service (QoS) requirements of different services in a New Radio (NR) vehicle to everything (V2X) system and to avoid or reduce unnecessary SR triggering. The method includes that a network device sends a first message to a terminal device, where the first message includes a first identifier and one or more configuration parameters corresponding to the first identifier. The first identifier is of a first logical channel, and the first logical channel is of a sidelink (SL) radio bearer. Alternatively, there is a mapping relationship between the first identifier and the first logical channel.

Abstract: A low density parity check (LDPC) channel encoding method is used in a wireless communications system. A communication device encodes an input bit sequence by using an LDPC matrix, to obtain an encoded bit sequence for transmission. The LDPC matrix is obtained based on a lifting factor Z and a base matrix. The base matrix may be one of eight exemplary designs. The encoding method can be used in various communications systems including fifth generation (5G) telecommunication systems, and can support various encoding requirements for information bit sequences with different code lengths.
