摘要： A base station apparatus includes a classification unit configured to classify user apparatuses based on channel state of a radio link, a DRX (Discontinuous Reception) status memory configured to store information indicating which of multiple groups each of one or more of the user apparatuses conducting DRX belongs to, a determination unit configured to determine which of the groups the user apparatuses classified by the classification unit are to belong to with reference to the information stored in the DRX status memory, and an indication unit configured to indicate the determined groups to the user apparatuses. Each of the groups includes one or more of the user apparatuses activating simultaneously. The determination unit is configured to assign one of the user apparatuses having relatively poor channel state to one of the groups having a smaller number of simultaneously activating user apparatuses.

摘要： A radio communication method in which a mobile station receives signaling information transmitted by a base station via a shared control channel, detects a presence/absence of data addressed to the mobile station, demodulates a shared data channel when the data is present, and receives data transmitted by the base station. The method includes the steps of transmitting, from the base station to the mobile station, a synchronization request via the shared control channel and transmitting, at the mobile station, feedback information including channel quality information, as a response to the synchronization request, via a random access channel. The method also includes generating, at the base station, timing advance information when receiving the feedback information, and transmitting, from the base station to the mobile station, the timing advance information, and adjusting, at the mobile station, a transmission timing of uplink data based on the timing advance information.

摘要： A communication control method used by a base station to allocate a radio resource to a user terminal which performs different-frequency measurement includes the steps of transmitting to the base station, by the user terminal, a request indicating whether a measurement gap for different-frequency measurement is needed, when a need for data communications between the user terminal and the base station arises while the user terminal is performing discontinuous reception; and controlling, by the base station, the radio resource allocated to the user terminal based on whether the measurement gap is needed.
