PROBLEM TO BE SOLVED: To provide a wireless communication infrastructure entity executing signaling of scheduling grant or allocation information in a wireless communication system, for instance, redundancy version, transport block size or both of them. SOLUTION: This wireless communication infrastructure entity includes a transceiver, and a controller communicably coupled to the transmitter. The controller is configured to generate parity bits based on scheduling grant information and to encode the parity bits based on additional scheduling grant information not used to generate the parity bits, wherein the encoded parity bits are combined with the scheduling grant information.

Abstract:
A wireless communication device (200) including a first CRC coder that generates a first block of CRC parity bits on a transport block and associates the first block of CRC parity bits with the transport block, a segmenting entity that segments the transport blocks into multiple code blocks after associating, and a second coder that generates a second block of CRC parity bits on each code block and associates a second block of CRC parity bits with each code block. The first and second blocks of CRC parity bits are based on first and second generator polynomials. In one embodiment, the first and second generator polynomials are different. In another embodiment, the generator polynomials are the same and the transport block is interleaved before segmenting or the code block are interleaved before encoding with the second block of CRC parity bits.
