Abstract: This application provides a wireless communication method and device. The method includes: obtaining downlink control information DCI and a scrambled sequence that are sent by a network device, where bits corresponding to the scrambled sequence are scrambled with each piece of configuration information of a plurality of pieces of configuration information used for configuring a terminal device by the network device, each piece of configuration information corresponds to at least one bit in the scrambled sequence, and at least one bit of the bits that correspond to each piece of configuration information does not correspond to another piece of configuration information of the plurality of pieces of configuration information; descrambling, based on a possible value of each piece of configuration information, the bits that correspond to each piece of configuration information, to obtain a descrambled sequence; and performing a check operation by using the descrambled sequence and the DCI.

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.
