Abstract  Abstract

This invention claims a start point of redundancy version in the circulating rate matching operation method and device. At least one code to transmit the information bit block and then segmented into a plurality of sub-blocks of coded bits. Collecting coding bit and marking by interleaving of a plurality of sub-blocks in a plurality of redundancy versions comprise a circular buffer each redundancy version corresponding to a starting bit index in the circular buffer. For each time transmission for selecting bits from the circular buffer by selecting a redundancy version of the electronic unit. Bit modulation of the selected subset and sending by the at least one antenna. A redundancy version the first redundancy version a number of bits between the beginning of the second redundancy version is not to be at least one modulation order removing.

Methods and apparatus for determining the starting points of redundancy versions in a circular rate matching operation. At least one block of information bits to be transmitted are encoded then segmented into a plurality of sub-blocks of coded bits. The interleaved coded bits of the plurality of sub-blocks are collected and filled into a circular buffer having a plurality of redundancy versions in the circular buffer with each redundancy version corresponding to a starting bit index in the circular buffer. For each transmission a subset of bits is selected from the circular buffer by selecting a redundancy version. The selected subsets of bits are modulated and are transmitted via at least one antenna. The redundancy versions the number of bits between the starting point of a first redundancy version and the starting point of a second redundancy version is not divisible by at least one modulation order.
