Abstract: Embodiments of this application disclose a synchronization method and a device. A device marks, based on a preset period, a periodic code block in a data bitstream to be sent from a MAC layer to a PHY layer. The device sends the data bitstream to a peer device through the PHY layer, records a sending time of each periodic code block as a first timestamp during sending, and returns the first timestamp to the MAC layer. By marking a timestamp for the periodic code block received from the MAC layer, the device sets a PHY-layer-based time reference scale (namely, the first timestamp) at the PHY layer.

Abstract: According to embodiments of the present disclosure, a method and a chip for cyclic code encoding, a circuit component, and an electronic device are provided. The method includes: generating, based on a first symbol sequence related to a first part of symbols in the K payload symbols, a first parity sequence corresponding to the first symbol sequence; generating, based on a second symbol sequence related to a second part of symbols in the K payload symbols, a second parity sequence corresponding to the second symbol sequence, where the first part of symbols are different from the second part of symbols; generating the (N−K) parity symbols based on the first parity sequence and the second parity sequence.
