Abstract: Embodiments of the application provide a method for transmitting data in a wireless communication network. A device of the network receives a bit sequence of K information bits. The device polar codes the bit sequence to obtain a first encoded sequence, wherein a length of the first encoded sequence is N, and N is greater than or equal to K. The device block interleaves the first encoded sequence to obtain an interleaved bit sequence. The device determines a transmission code rate R. When the transmission code rate R is less than the code rate threshold, the device outputs a second bit sequence. The length of the second bit sequence is M, M is smaller than N. The second bit sequence is punctured from the interleaved bit sequence by removing (N-M) bits from beginning of the interleaved bit sequence.

Abstract: This application provides a gateway handover method and an apparatus, to ensure the reliability of a gateway handover of a terminal device and reduce hardware overheads in a gateway handover process. The terminal device receives a synchronization signal/PBCH (physical broadcast channel) block (SSB) from a network device through a service link. The SSB includes an SSB of a source gateway and an SSB of at least one candidate target gateway. The terminal device obtains a measurement value of channel quality corresponding to the SSB of the at least one candidate target gateway, and sends a measurement result to the network device. The network device forwards the measurement result to the source gateway, which determines, based on the measurement result, whether to hand over the terminal device from the source gateway to one of the at least one candidate target gateway.
