Abstract: Methods of selecting a transport format combination are provided. For example, a method comprises calculating the transmission power of a first physical channel using each of first TFCs, and determines whether a mobile station is in a transmission capable state. The method also comprises calculating the sum of the transmission power of first and second physical channels using first and second TFCs, with respect to each of combinations of first and second TFCs, and determines whether the mobile station is in the transmission capable state. The method also comprises selecting first TFC from the first TFCs wherein the mobile station is in the transmission capable state and selecting a second TFC from the second TFCs which are included in combinations wherein the mobile station is in the transmission capable state among the combinations including the selected first TFC. The data is transmitted using the selected first and second TFCs, respectively.

Abstract: It is possible to solve the problem that a downstream control information amount is significantly increased if allocation information is periodically reported because no allocation method of a default E-DCH resource configuration is defined for a preamble signature. A base station and a mobile station decide a default resource configuration by using a total number of resource configurations or a value obtained from the total number.

Abstract: To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.

Abstract: Even when a radio terminal cannot receive contents data from a serving base station, the radio terminal can receive the contents data from other base station. A wireless communication system includes a radio terminal, a serving radio base station to which the radio terminal serves, and a non-serving radio base station to which the radio terminal does not serve. The serving radio base station receives, from the non-serving radio base station, contents-related information concerning contents data to be broadcasted or multicasted by said non-serving radio base station, and transmits the received contents-related information to the radio terminal.
