  • Patent number: 8184577
    Abstract: A method of setting a transport block size for a user equipment in a wireless communications system includes providing a combination table for being looked up to generate a parameter value according to a combination of a modulation scheme and a number of channelization codes indicated by a base station, so as to decide a transport block size index, and configuring a first parameter value corresponding to a least resource usage in the combination table as a first transport block size index before deciding the transport block size index. The first transport block size index is a transport block size index corresponding to a smallest transport block size in a transport block size table, and the combination table and the transport block size table are used when quadrature phase shift keying (QPSK) modulation, 16 quadrature amplitude modulation (16QAM) or 64 quadrature amplitude modulation (64QAM) is activated.
