    Abstract: Methods, apparatus and systems for determining a transport block size in a wireless communication are disclosed. In one embodiment, a method performed by a wireless communication device is disclosed. The method comprises: receiving control information from a wireless communication node, wherein the control information includes a plurality of transmission parameters related to transport blocks to be transmitted between the wireless communication device and the wireless communication node; calculating an intermediate transport block size (TBS) for the transport blocks based on the plurality of transmission parameters; modifying the intermediate TBS to generate a modified TBS in response to an event that the intermediate TBS is smaller than a threshold; and determining a final TBS for the transport blocks based on a TBS that is closest to the modified TBS, among TBSs that are in a quantized set and not smaller than the modified TBS.

    Abstract: Provided are a data checking method and device. The method includes: receiving a transmission signal containing a first data block and transmitted by a transmission node, wherein the length of the first data block is N bits, the first data block is generated by performing an FEC encoding on a second data block which has a length of K bits, and the second data block is generated by performing a CRC encoding on a third data block which has a length of L bits, where N, K and L are all positive integers, and N≧K>L; obtaining a first estimation data block of the first data block according to the transmission signal, and obtaining a second estimation data block of the second data block according to the transmission signal; and checking the third data block according to a relationship between the first estimation data block and an FEC code space and/or a CRC check result of the second estimation data block. By means of the technical solution provided in the present disclosure, the problems that a transmission rate decreases due to the fact that a CRC check code is too long and a false detection rate cannot be ensured due to the fact that the CRC check code is too short are solved.
