Abstract: Example wireless communication methods and apparatus are described. In one example method, a Bluetooth sending apparatus generates and sends a first Bluetooth data frame to a Bluetooth receiving apparatus. The first Bluetooth data frame includes a first access code, a first synchronization code, and a first data field, and the first synchronization code is located before the first data field. When performing at least one of autocorrelation or cross-correlation, the first synchronization code provides a higher success rate of at least one of synchronization detection or data receiving than the first access code.

Abstract: This application provides a short-range wireless communication method and a related device. The method includes: generating a transmission frame. 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.

Abstract: 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 ( )}a and a maximum-length segment that has the maximum segment code length of 2{circumflex over ( )}b. 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.
