Patent ID: 7061892

Claim:
An information communication method of performing communication using a plurality of channelization codes based on code division multiple access, comprising: receiving a modulation scheme for use in the code division multiple access, a number of the channelization codes assigned to a mobile station, and an identification code corresponding to a transport block set size; and identifying the transport block set size based on the received identification code corresponding to the transport block set size; wherein the identification code corresponding to the transport block set size is continuous numbers expressed by combining bits assigned for signaling of the identification code corresponding to the transport block set size, and the transport block set size belongs to a first set of transport block set sizes or a second set of transport block set sizes different from the first set of transport block set sizes, and the transport block set size included in the first set of the transport block set sizes is obtained by a part of the continuous numbers, the modulation scheme, and the number of the channelization codes, and the transport block set size included in the second set of the transport block set sizes is different from that included in the first set of the transport block set sizes.
