    Abstract: The present disclosure relates to the field of communication technologies, and provide a near-field communication (NFC) chip, a phase synchronization method, and an electronic device, to quickly synchronize a transmitted signal of an NFC card device with a carrier of an NFC card reader. The NFC chip includes a processing circuit configured to: determine a first carrier frequency offset between a local clock signal and a carrier clock signal, and generate a first frequency control word based on the first carrier frequency offset. The carrier clock signal is determined based on a received signal received by the NFC chip. The NFC chip further includes a phase-locked loop configured to generate a first clock signal based on the local clock signal and the first frequency control word. The NFC chip also includes a phase alignment circuit configured to perform phase selection on the first clock signal based on the carrier clock signal to obtain a second clock signal, and send the second clock signal to a transmitter circuit.

    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.

    Abstract: This application relates to a communication method and apparatus using an unlicensed spectrum, applied to the field of short-range communication, and in particular, to scenarios such as smart driving, smart home, and intelligent manufacturing. The method includes: generating broadcast information; and sending the broadcast information on at least one broadcast channel on a predefined frequency band, where the at least one broadcast channel includes a first broadcast channel, and a center frequency of the first broadcast channel is 2403 MHz, 2404 MHz, 2420 MHz, 2421 MHz, 2422 MHz, 2423 MHz, 2424 MHz, or 2481 MHz. According to a broadcast channel configuration manner in this solution, signal interference on the unlicensed spectrum can be reduced, and communication quality can be improved.

    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.
