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: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.

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.

IPC: H04L1/00
Abstract: This application provides a method for communicating a modulation and coding scheme (MCS). A terminal device obtains a modulation order, a code rate, or a spectral efficiency, determines an index of a reference MCS from a mapping table based on the obtained modulation order, code rate, or spectral efficiency, and reports the index of the reference MCS to a network device. The mapping table includes one or more mapping relationships between an MCS index and a modulation order, a code rate, or a spectral efficiency. The terminal device may process uplink or downlink data based on the determined MCS, thereby improving data transmission reliability.

Abstract: Embodiments of the application provide a polar coding method for communicating information in a wireless network. Information bits are encoded using a polar code process to obtain a polar-coded bit sequence. A rate matched bit sequence is output based on the polar-coded bit sequence. The rate matched bit sequence includes a quantity M of bits from the polar-coded bit sequence, and the M bits from the polar-coded bit sequence correspond to M channel indexes in a channel index sequence S. The channel index sequence S is obtained based on a puncturing/shortening proportion P′ and a prestored channel index sequence S′. Channel indexes in the prestored channel index sequence S′ are sorted by channel reliability or channel capacity, and a sorting order of the M channel indexes in the channel index sequence S is the same as a sorting order of the channel indexes in the prestored channel index sequence S′.

Abstract: Embodiments of this application provide a method for transmitting encoded information. A communication device obtains K bits of information, and generates a to-be-encoded sequence u1N, wherein N is a length of the sequence. The device encodes the sequence u1N in an encoding process, to obtain an output sequence, and transmits the output sequence. In the sequence u1N, each of the N bits corresponds to a subchannel, and each subchannel has a reliability. The K information bits, a quantity J of first-type auxiliary bits, and a quantity J′ of second-type auxiliary bits are placed in K′=K+J+J′ bit positions of the sequence u1N according to reliabilities of the subchannels. Since the positions of the information bits and the auxiliary bits are pre-determined and not affected by subsequent encoding and rate-matching, overheads of real-time reliability calculation are effectively reduced, time is saved, and delay is reduced.
