The mobile station includes a radio communication that transmits an access request message to a base station via a first communication resource, and receives a timing adjustment in response to the access request message from the base station. The mobile station also includes an adjustment value storage unit that stores the timing adjustment, and a control unit that adjusts access timing corresponding to a second communication resource based on the timing adjustment value stored in the adjustment value storage unit. The radio communication unit then communicates with the base station via the first communication resource and the second communication resource.

摘要： Suitable beam pattern control is performed while performing access control based on physical carrier sense.A communication device transmits frames having a long preamble under a state where signals will not reach unless a beam pattern is formed, thereby enabling access control based on physical carrier sense, and under a state where signals will sufficiently reach without a beam pattern being formed transmits frames having a shorter preamble, thereby suppressing transmission overhead. Also, a beam pattern and preamble type are decided based on transmission/reception history of access control following CSMA/CA procedures.

摘要： User equipment performs radio communication with a base station over a communication channel formed by aggregating a plurality of component carriers. The user equipment measures a channel quality of the communication channel, and creates a measurement report using a result of the measurement and sends the measurement report to the base station. Each data signal is classified into two or more classes depending on a QoS requirement. The user equipment further receives control information related to a mapping between the plurality of component carriers and the class of each data signal from the base station, and controls at least one of the measurement and the sending of the measurement report, according to a procedure which varies depending on the control information. A base station allocates data to component carriers based on channel quality criteria for different data classifications.
