The transmission frame includes a frame header and a data domain, phase shift keying modulation is used for the frame header, and quadrature amplitude modulation or phase shift keying modulation is used for the data domain. The method includes sending the transmission frame. In this application, the phase shift keying modulation is used for the frame header of the transmission frame, and the phase shift keying modulation or the quadrature amplitude modulation with a same bandwidth is used for the data domain.

Short-range wireless communication method and related device

Methods, devices, and computer-readable storage media are disclosed. In an example method, segmentation of to-be-encoded information bits of a length N into respective quantities of different types of segments is performed. The different types of segments are among (b−a+1) types of segments that correspond to (b−a+1) different segment code lengths. The (b−a+1) types of segments comprise a minimum-length segment that has the minimum segment code length of 2{circumflex over ( )}and a maximum-length segment that has the maximum segment code length of 2{circumflex over ( )}. The respective quantities of the different types of segments are determined based on the length N and a code rate in an orderly manner, wherein the orderly manner comprises firstly determining a quantity of the maximum-length segments and lastly determining a quantity of the minimum-length segments. Polar code encoding is performed on the respective quantities of the different types of segments of the to-be-encoded information bits.

Polar code segment encoding method and communication device

A method includes determining, based on a length of to-be-encoded information bits and a code rate, a code length N after encoding; determining, based on N, a minimum segment code length and a maximum segment code length, a reserved segment quantity of each type of segments in segments of b−a+1 types of segment code lengths and a reserved code length corresponding to N, where the minimum segment code length is 2{circumflex over ( )}, and the maximum segment code length is 2{circumflex over ( )}; determining a segment quantity of each type of segments based on N, the reserved code length, a segment code length of each type of segments, and the reserved segment quantity, where N corresponds to S segments, and a segment code length of an isegment in the S segments is greater than or equal to a segment code length of an (i+1)segment in the S segments.
