Abstract: A bandwidth part switching method, is applicable to a non-terrestrial network (NTN) to implement BWP switching based on multi-color frequency-division multiplexing. In the method, a terminal device may report, in a second BWP to a network device, an index of a first SSB whose signal quality is greater than or equal to a first threshold in one or more SSBs in a first BWP, and switch from the second BWP to a third BWP. The one or more SSBs correspond to at least one BWP other than the first BWP, and the third BWP is in the at least one BWP and corresponds to the first SSB. After receiving the index of the first SSB in the second BWP, the network device determines the third BWP, and performs service data transmission with the terminal device in the third BWP.

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: An interleaving method and apparatus are provided, to reduce complexity of implementation processes of polar code interleaving and rate matching. The method includes: obtaining encoded bits after polar code encoding, and sorting the encoded bits based on a priority order of performing a rate matching operation, to obtain a first bit sequence. The first bit sequence includes j subsequences, and j is a positive integer. The method further includes writing the first bit sequence into an interleaver of i rows and j columns. Bits in a column in the interleaver include one of the j subsequences; and reading out bits from the interleaver column by column, until M bits are read. At least two adjacent columns have opposite readout directions, and M is a target code length.
