摘要： A reception unit receives data from communication apparatuses. A transmission unit transmits data to the communication apparatuses. A control unit determines, in an adaptive way, which modulation and coding schemes to use to transmit and receive data. At a first stage, a modulation and coding scheme with a low transmission rate or a modulation and coding scheme that minimizes power requirements is selected from among a plurality of candidates therefor. At a second stage, the modulation and coding scheme of at least one of the communication apparatuses is changed to another scheme having a higher transmission rate, when it is impossible to allocate sufficient resources for the modulation and coding schemes selected at the first stage.

摘要： Upon detection of an environmental change in a neighborhood, a cellular phone makes selections of a communication device and a communication path, which are used for a communication. A communication packet transmitted from a communication corresponding terminal is distributed to the cellular phone that is the destination of the communication packet, and a PC physically positioned in the neighborhood of the cellular phone, according to the results of the selections, thereby switching from a communication using only the cellular phone to a communication using both the cellular phone and the PC.

摘要： A wireless base station monitors a state of reception in a common transmission region (channel) in a wireless frame common to a plurality of wireless terminals, and controls allocation of a transmission region in the wireless frame to be used for transmission by the wireless terminals on the basis of a result of the monitoring and information about priority set to each of the plural wireless terminals. The wireless resource can be preferentially allocated to a wireless terminal of a user having high priority even when the common communication region used to obtain permission to send a bandwidth request is congested.
