Abstract: This application provides an encoding method and apparatus in wireless communications between a network device and a terminal. The method includes: performing cyclic redundancy check (CRC) encoding on A to-be-encoded information bits based on a CRC polynomial, to obtain a first bit sequence, where the first bit sequence includes L CRC bits and A information bits, L=11; and performing polar encoding on the first bit sequence.

Abstract: A resource mapping method and apparatus and a resource mapping indication method and apparatus are provided to adapt to an interference cancellation function of a receiver. The method is: A network device obtains a mapping mode used for resource mapping during uplink transmission. The network device sends, to a terminal, information indicating the mapping mode. The mapping mode is used to indicate mapping locations of a plurality of modulation symbols in a resource mapping block RMB, the RMB comprises a plurality of resource elements REs, and at least one RE carries at least two modulation symbols.

Abstract: This application provides an encoding method and apparatus in a wireless communications system. The method includes: performing cyclic redundancy check (CRC) encoding on A to-be-encoded information bits based on a CRC polynomial, to obtain a first bit sequence, where the first bit sequence includes L CRC bits and the A information bits; and performing polar encoding on the first bit sequence, where L has a value of one of 3, 4, 5, 8, and 16. Based on an improved CRC polynomial, coding satisfying a false alarm rate (FAR) requirement is implemented.
