摘要： A system and method for rate matching to enhance system throughput based on packet size is provided. A method for transmitting information includes encoding a block of N bits, where N is an integer, demultiplexing the encoded block of N bits into at least one subblock of systematic bits and at least one subblock of parity bits, and permuting the at least one subblock of systematic bits and the at least one subblock of parity bits to generate at least one permuted subblock. The method also includes forming at least one output block from the at least one permuted subblock, computing a starting position of a redundancy version for a hybrid automatic repeat request (HARQ) transmission based on a relationship between N and a threshold, and transmitting the redundancy version. The redundancy version begins at the computed starting position and ends when a specified number of bits has been transmitted.

摘要： In a communication method, a sequence of information bits is encoded into systematic bits and parity bits. The systematic bits and the parity bits are grouped in output blocks, each output block to be assigned to an address of a constellation scheme. The addresses include addresses that are more prone to error and address that are less prone to error so that the symbols are grouped such that bits in groups of consecutive bits of the sequence of information bits are not all assigned to addresses that are more prone to error.
