Abstract: This application provides a polar code transmission method and apparatus. The method includes: transforming a to-be-processed bit sequence at two or more different granularities, where each specific manner at a first granularity is used to implicitly indicate one value in one level of time sequence information, and each specific manner at a second granularity is used to implicitly indicate one value in another level of time sequence information; and sending the transformed (processed) bit sequence, so that different encoded bit sequences can be obtained, and more versions of time sequence information can be implemented, thereby meeting a requirement of transmission in a plurality of levels of time sequences.

Abstract: A polar code encoding method and apparatus are provided. The method includes: obtaining a basic sequence, where the basic sequence is a sequence obtained by sorting sequence numbers of polarized channels in descending order or ascending order of reliability, and a length of the basic sequence is L1; determining, based on a maximum encoding length L2 supported by a receiving device, a quantity M of segments of an information bit sequence whose length is N after encoding, where a quantity of bits in the information bit sequence before the encoding is K; and performing polar code encoding on the M segments based on the basic sequence. According to the polar code encoding method, during polar code construction, an encoding device needs to know only a reliability order of min(N/M, L1) polarized channels. In this way, storage overheads of a nested sequence can be effectively reduced, and online computing complexity can be reduced.

Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting pattern information. The method for transmitting pattern information includes obtaining pattern information; and sending the pattern information to UE. The first pattern information indicates that the spectrum of the first cell is allocated to the first RAT in a first plurality of sub-frames, and that the spectrum of the first cell is allocated to the second RAT in a second plurality of sub-frames. The first pattern information enables the UE to select any sub-frame in the first plurality of sub-frames to measure a CRS if the UE RAT pattern corresponds to the first RAT, or enables the UE to select any sub-frame in the second plurality of sub-frames to measure the CRS if the UE RAT pattern corresponds to the second RAT. The embodiments of the present invention improve scheduling accuracy and efficiency.

Abstract: This application provides example concatenated code encoding and decoding methods. In one example method, polar code encoding is performed on a to-be-encoded message bit sequence based on a frozen bit set and a message bit set that are of a first polar code, to obtain a first encoded code word whose length is N_o. The first encoded code word is interleaved to obtain a second encoded code word, and optimized low-density parity-check (LDPC) code encoding is performed on the second encoded code word to obtain a concatenated code word. Interleaving includes both outer interleaving and inner interleaving. The concatenated code word is then outputted.

Abstract: A communication method and a communication apparatus. A terminal device obtains a first SSB. The terminal device sends a random access preamble corresponding to the first SSB. The random access preamble is carried at a first time domain position. The first time domain position is associated with a timing offset value. The timing offset value is determined based on a round-trip delay between the network device and a first position in an area covered by the network device.

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.
