Patent ID: 7532602

Claim:
An information communication method in a base station of performing communication using a plurality of channelization codes based on code division multiple access, comprising: transmitting to a mobile station a modulation scheme for use in the code division multiple access, a number of the channelization codes assigned to the mobile station, and an identification code corresponding to a transport block set size, wherein the transmitted identification code corresponding to the transport block set size is continuous numbers, and the continuous numbers are transmitted to the mobile station by using bits which are assigned for signaling of the identification code corresponding to the transport block set size, 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, the transport block set size included in the first set of the transport block set sizes can be obtained in the mobile station 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.
