摘要： A method and apparatus for providing adaptive cyclic redundancy check (CRC) computation is disclosed. A transport block size is determined. Transport block (TB) CRC bits are computed with a first CRC generator when the TB size is less than or equal to a predetermined threshold. TB CRC bits are computed with a second CRC generator when the transport block size is greater than the predetermined threshold. When the TB is greater than the predetermined threshold, the TB is segmented into code blocks (CBs) and CB CRC bits are computed with the first CRC generator. A method and apparatus for handling adaptively cyclic redundancy check (CRC) encoded transport blocks (TBs) is also disclosed. A TB is received. The TB is CRC checked based on a first CRC generator when the TB size is less than or equal to a predetermined threshold. Code blocks of the TB are CRC checked based on the first CRC generator when the TB size is greater than the predetermined threshold. When the TB size is greater than the predetermined threshold, the code blocks are concatenated, and the TB is CRC checked based on a second CRC generator.

摘要： A method in a radio network node for estimating channel gain over frequencies of a bandwidth in a radio communications network. The radio network node measures a first channel gain based on a received power of a sounding reference signal over a first set of frequencies from a user equipment, which first set of frequencies is comprised in the frequencies of the bandwidth. Furthermore, the radio network node measures a second channel gain based on a received power of a received demodulation reference signal of a physical uplink shared channel over a second set of frequencies from the user equipment, which second set of frequencies is comprised in the frequencies of the bandwidth. The radio network node then estimates a third channel gain over the frequencies of the bandwidth based on the measured first channel gain and the measured second channel gain.
