摘要： There is a problem that when a closed subscriber group (CSG) cell (1303) available to subscribers is installed in a macro cell area (1301), communication cannot be performed due to the interference between a macro cell (1302) and the CSG cell (1303) in an area (1304) thereof. The CSG cell (1303) that is provided in the CSG cell area (1304) and transmits a downlink synchronization signal using a radio frame assigns control signals to a first subframe and a second subframe among a plurality of subframes constituting the radio frame, and the macro cell (1302) that is provided in the macro cell area (1301) and transmits a downlink synchronization signal using the radio frame assigns control signals to a third subframe and a fourth subframe, which are shifted from the first subframe and the second subframe by a predetermined number of subframes, respectively, among the plurality of subframes constituting the radio wave, the CSG cell (1303) and the macro cell (1302) being configured to perform transmission in synchronization with each other.

摘要： 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 (2) temporarily stops supply of electric power to the data transmission processing units and the data reception processing units of the mobile terminal (3).

摘要： A mobile communication system includes a plurality of eNBs that perform radio communication with an UE and an MCE that controls the eNBs. The MCE indicates an MBSFN subframe (MCE) serving as radio resources that transmit a reference signal for power measurement to the UE less frequently than normal to the eNB, the eNB, in addition to the MBSFN subframe (MCE) indicated by the MCE, designates the MBSFN subframe (eNB) serving as the radio resources that transmit a reference signal to the UE less frequently than normal, and in the MBSFN subframe (MCE) and the MBSFN subframe (eNB) the reference signal is transmitted to the UE. In this manner, the reference signal for measuring a power can be transmitted less frequently than normal, and a power consumption of the infrastructure can be reduced.

摘要： The present invention has an object to provide a communication system of improving the communication quality in a case where a plurality of communication devices having different sizes of ranges coexist, in which communication with a terminal device is possible, to thereby improve an entire throughput. In a case where a remote radio head (RRH) is installed in a coverage of a macro cell, an uplink resource transmitted from a user equipment (UE) to the macro cell, that is, an uplink carrier frequency band UL1 of the macro cell in a portion surrounded by a solid line is received not only by the macro cell but also by the RRH. Then, the macro cell combines a reception signal regarding the uplink resource of the macro cell, which has been received by the macro cell, and a reception signal regarding the uplink resource of the macro cell, which has been received by the RRH.
A base station supporting a primary cell informs the UE of timing advances for the primary cell and a secondary cell for performing radio communication via carrier aggregation simultaneously over the primary cell and the secondary cell.-

摘要： A mobile communication system hybridly allows, in a case where an access group consisting of one or more user equipments and one or more base stations is registered, the base station included in the access group to have access in a closed mode from the user equipment included in the same access group and access in an open mode from a user equipment that is not included in the same access group, wherein a communication area of the base station in the open mode is identical to a communication area of the base station in the closed mode. This eliminates a communication area in which the base station serving as an access destination differs between the user equipment in the closed mode and the user equipment in the open mode.

摘要： In an MBMS transmission dedicated cell, only a downlink is provided and no uplink is provided. A method of transmitting a paging signal to a mobile terminal in this MBMS dedicated cell is established. A communication system has three types of cells including, in addition to the MBMS dedicated cell, a unicast cell to and from which a mobile terminal can transmit and receive dedicated communication data, and a unicast/MBMS-mixed cell which can provide both a service provided by the unicast cell and a service provided by the MBMS dedicated cell. While receiving the broadcast type data transmitted from the MBMS dedicated cell, the mobile terminal makes a notification of an MBMS receiving state via the unicast cell or the unicast/MBMS-mixed cell to transmit information for identifying the MBMS dedicated cell which is transmitting the broadcast type data which the mobile terminal is receiving, and the communication system transmits a paging signal to the mobile terminal currently receiving the broadcast type data transmitted from the MBMS dedicated cell on the basis of a tracking area (Tracking Area) in which the mobile terminal is tracked, the tracking area being determined on the basis of the information transmitted.
