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: A polar code coding/decoding method, a sending device, and a receiving device are disclosed. The method includes: selecting, by a sending device, K non-punctured-position sequence numbers as a reference sequence number set based on a quantity K of information bits and a reliability-based order of N polarized channels of a polar code whose code length is N, where a reliability of a polarized channel corresponding to any sequence number in the reference sequence number set is greater than or equal to reliabilities of polarized channels corresponding to remaining (N−K) sequence numbers; determining, by the sending device, an information-bit sequence number set based on a determining condition and the reference sequence number set; and performing, by the sending device, polar coding on to-be-coded bits based on the information-bit sequence number set.

Abstract: A method, an apparatus, and a system for detecting a radio network problem are disclosed. The method includes: when a radio network problem occurs on a user equipment (UE), a first base station controlling a cell that a radio resource control (RRC) connection established with the UE, receives problem information about the radio network problem sent by the UE, in a procedure of re-establishing the RRC connection by the UE, and sends the problem information to a second base station controlling a cell where the radio network problem occurs.

Abstract: A method includes: obtaining a first sequence corresponding to a basic code length N0; determining N to-be-encoded bits, where the N to-be-encoded bits include N2 fixed bits, and N is greater than the basic code length N0; extending the first sequence to obtain a second sequence; determining locations of the N2 fixed bits in the N to-be-encoded bits based on polar channel serial numbers indicated by first N2 elements in the second sequence; and performing polar encoding on the N to-be-encoded bits to obtain encoded bits. The locations of the fixed bits in the N to-be-encoded bits are determined based on the second sequence, and the second sequence is obtained by extending the first sequence corresponding to the basic code length N0.

Abstract: Method and apparatus for transmission and reception with polar codes are provided to support up to 16 permutations or transformation mappings. For example, 16 versions of copies able to be soft-combined for PBCH or any other data channel or control channel are suggested if the mother code length is 256 or 512 or 1024. With the new design, up to 16 different versions can be used to soft combined to improve the performance. Some sequences are provided as examples to support 16 different permutation patterns. The inverse of these sequences also have the feature to support 16 different permutation patterns.

Abstract: Aspects of this disclosure provide a technique for implementing polar encoding with incremental redundancy HARQ re-transmission. In particular, a transmitter encodes a message using different polar codes to obtain a first codeword and a second codeword that is twice the length of the first codeword, and transmit the first codeword as an original transmission, and the second half of the second codeword as a re-transmission without transmitting the first half of the second codeword. Information bits that are common to both the first codeword and the second half of the second codeword is mapped to more-reliable bit-locations in the second half of the second codeword. Decoded bit values for the common information in the original transmission and retransmission is compared by the receiver to perform a parity check.
