Abstract: In a cell handover method and apparatus, first network device of a first cell obtains user information of a terminal device, and then the first network device may determine handover information based on the user information and running information of the first network device, so that after the first network device sends an RRC message including the handover information to the terminal device, the terminal device may perform N consecutive cell handovers based on the handover information. In the N cell handovers, the first network device only needs to obtain the user information once, to configure handover conditions for the N subsequent handovers in advance at a time. This simplifies a network signaling procedure, reduces network overheads, and reduces handover response time. The embodiments of this disclosure are applicable to a network handover in a satellite scenario.

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.
