Abstract: A polar code encoding method and apparatus are provided, to improve accuracy of reliability sorting of polar channels. The method is: determining a sorted sequence used to encode to-be-encoded bits, where the sorted sequence is used to represent reliability sorting of N polar channels, N is a mother code length of a polar code, and N is a positive integer power of 2; and performing polar code encoding on the to-be-encoded bits by using the sorted sequence, to obtain encoded bits.

Abstract: A terminal synchronization method and a terminal relate to the communications field, where the terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals such that terminals in a vehicle to vehicle communications system can have uniform timing. The method includes obtaining, by a terminal, a configurable transmission period for sending a first synchronization signal, and sending, by the terminal, the first synchronization signal based on the configurable transmission period.

Abstract: When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and a PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity.

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.
