摘要： A wireless communication transmitter (200) configured to segment a transport block into C segments, encode each segment into a set of encoded bits, determine, for γ encoded segments, a subset of size M0′ of encoded bits for each encoded segment and for C−γ encoded segments, a subset of size M1′ of encoded bits for each encoded segment, wherein the subset sizes M0′ and M1′ differ at most by P bits, where P is a product of a modulation order and a number of transmission layers over which the transport block is transmitted. The selected subsets of encoded bits are concatenated and grouped to form modulation symbols of the modulation order.

摘要： A communication device is disclosed. The device is configured to generate a first block of first cyclic redundancy check (CRC) parity bits on a transport block wherein the first block of CRC parity bits is based on a first generator polynomial, to attach the first block of CRC parity bits to the transport block and to segment the transport block into multiple code blocks. The processor is also configured to generate a second block of CRC parity bits on each code block wherein each of the second blocks of CRC parity bits is based on a second generator polynomial that is different than the first generator polynomial. The first and second generator polynomials have a common degree. A second block of CRC parity bits is attached to each code block, and the code blocks are concatenated after channel encoding.

摘要： A method and apparatus for rate matching is described. During operation of a transmitter, multiple data streams are received and individually interleaved with a permutation of a same length KΠ. A permutation (πp0) of a second stream is the same as a permutation (πsys) of a first stream and a permutation (πp1) of a third stream is different from the permutation of the first stream. Each element of πp1 is derived from the corresponding element of πsys. The plurality of interleaved streams are multiplexed to form a circular buffer. Finally, data is transmitted from the circular buffer.

摘要： In a multi-carrier communication system employing adaptive modulation and coding, a receiver feeds back channel quality information for a “binned” group of subcarriers instead of sending an individual quality report for each subcarrier. A transmitter will utilize the channel quality information for the bin to determine a set of γeff values corresponding to a set of modulation and coding scheme candidates, where γeff is an effective SNR that would yield a same FER in an AWGN channel. The transmitter utilizes the set of γeff values to aid in determining a modulation and coding scheme, and determine a single modulation and coding scheme for all subcarriers within the channel.
