Abstract: Aspects of this disclosure provide a technique for implementing polar encoding with incremental redundancy HARQ re-transmission. In particular, a transmitter may encode 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 may be 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 may be compared by the receiver to perform a parity check.

Abstract: The present invention relates to the field of communications network technologies, and discloses a data processing method and apparatus. In embodiments of the present invention, stream channel quality information is obtained, and then port mapping of a to-be-transmitted data stream is determined according to the stream channel quality information. The port mapping is used to make channel quality of data streams distributed in a same code word satisfy the following: a sum of fluctuation values that is used to represent channel quality of data streams in all code words is less than a sum of fluctuation values that is used to represent channel quality of data streams in all code words under original port mapping.

Abstract: Embodiments of this application provide an information transmission method and an apparatus. The transmit end sends a first coded bit sequence based on a to-be-transmitted coded bit sequence. The receive end receives and decodes a first to-be-decoded sequence, and sends first indication information if the decoding fails, where the first indication information includes information about a location, in the to-be-transmitted coded bit sequence, of at least one sent coded bit in the to-be-transmitted coded bit sequence. The transmit end receives the first indication information, and sends a second coded bit sequence based on the first indication information, where the second coded bit sequence includes the at least one sent coded bit in the to-be-transmitted coded bit sequence and/or at least one unsent coded bit in the to-be-transmitted coded bit sequence.

Abstract: A communication method and a communication apparatus are provided. The method includes: A first device receives first information, determines a target TR pattern based on the first information, and sends information or demodulates received information based on the target TR pattern, where the target TR pattern is a sub-pattern of a longest TR pattern, and the longest TR pattern includes a set of sub-carriers used as reserved tones. The longest TR pattern may include a plurality of TR sub-patterns of different lengths. For example, a first TR pattern of a first length is a sub-pattern of the longest TR pattern, and a second TR pattern of a second length is also a subset of the longest TR pattern. The TR sub-patterns of different lengths may correspond to different carrier bandwidths or quantities of RBs.

Abstract: Example random access methods and apparatus are described. In one example, the network device obtains a first random access preamble length of a first terminal device and a second random access preamble length of a second terminal device. The network device determines a first random access parameter of the first terminal device and a second random access parameter of the second terminal device based on the first random access preamble length and the second random access preamble length. The network device sends the first random access parameter and the second random access parameter to the first terminal device and the second terminal device respectively.

Abstract: This application provides a model training method and a related apparatus. In the method, a second communication apparatus receives a first neural network parameter of a first communication apparatus, and sends first indication information to the first communication apparatus when a correlation coefficient between the first neural network parameter and a second neural network parameter of the second communication apparatus is less than a first threshold. The first indication information indicates that the second communication apparatus is to participate in training of a first neural network model of the first communication apparatus. That the correlation coefficient between the first neural network parameter and the second neural network parameter is less than the first threshold indicates that the second neural network parameter makes a great contribution to convergence of the first neural network model.
