    Abstract: A UE in an idle state selects any of a group A, to which a cell of which coverage its own device is in, belongs and a group different from the group A, for example, a group B, and then measures cells belonging to the selected group for selecting a cell being a re-selection destination. A UE in a connected state selects any of the group B to which a cell connected with the UE belongs and a group different from the group B, for example, the group A, and measures cells belonging to the selected group for handover.

    Abstract: A mobile terminal 3 judges whether or not the mobile terminal is able to make a transition to a DTX period during Active, and, when judging that the mobile terminal is able to make a transition to a DTX period during Active, notifies a base station 2 to that effect. If the base station 2 judges that the mobile terminal is able to make a transition to a DRX period during Active when triggered by the notification from the mobile terminal 3, the base station temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal 3.

    Abstract: The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted. When calculated number of communication channels is one, a single communication channel is allocated based on quality information of a communication line to the terminal and, when calculated number of communication channels is more than one, then more than one communication channels are allocated based on the quality information. Allocation information used for notifying of allocated communication channels is generated based on virtual channels, which are defined in advance as channel units having a combination of a plurality of consecutive communication channels, and the allocation information is transmitted to the terminal.

    Abstract: A radio communication technology for enabling high reliability, a high transmission rate, and low power consumption is provided. A communication system includes a communication terminal and a base station. The base station includes a plurality of transmitter-receivers configured to perform radio communication with the communication terminal. The base station is configured to perform radio communication with the communication terminal by using a part or all of the plurality of transmitter-receivers. The communication terminal receives a downlink synchronization signal from at least one first transmitter-receiver to be newly connected, and establishes downlink synchronization with the at least one first transmitter-receiver by using the downlink synchronization signal. The communication terminal establishes uplink synchronization with the at least one first transmitter-receiver through random access processing.

    Abstract: A communication system that can reduce latency while preventing reduction in a transmission rate. An eNB communicates with a UE #1 using a self-contained subframe including a first downlink signal (DL #1) and a first uplink signal (UL #1), and with a UE #2 using a self-contained subframe including a second downlink signal (DL #2) and a second uplink signal (UL #2). The self-contained subframe for the UE #1 includes a first gap duration (Gap #1) during which neither the DL #1 nor the UL #1 is transmitted, between transmission durations of the DL #1 and the UL #1. The self-contained subframe for the UE #2 includes a second gap duration (Gap #2) during which neither the DL #2 nor the UL #2 is transmitted, between transmission durations of the DL #2 and the UL #2. The Gaps #1 and #2 are set to each UE.
