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: The present disclosure relates to access methods and apparatuses. In one example method, a terminal device determines, based on whether a first frequency offset parameter is in a frequency offset parameter range, whether to access a first cell. If the first frequency offset parameter is in the frequency offset parameter range, a current location of the terminal device is not at an edge of the cell. Otherwise, the current location of the terminal device may be at the edge of the cell.

Abstract: A communication method and a communication apparatus. In the method, a transmit end obtains to-be-encoded information, where the to-be-encoded information includes k bits, and k is a positive integer; the transmit end determines that a quantity of code blocks is C, and C is a positive integer; the transmit end performs polar encoding on the to-be-encoded information based on C, to obtain C encoded code blocks; and the transmit end sends the C encoded code blocks. In some implementations, the transmit end determines, based on k and a target bit rate, that the quantity of code blocks is C. In some implementations, the transmit end obtains the C encoded code blocks in a code block coupling manner.

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.
