Abstract: A base station according to a first aspect is configured to transmit a radio signal to a user terminal in an own cell by using a plurality of transmission antennas. The base station comprises: a controller configured to notify the user terminal of a multi-antenna transmission mode to be applied to a transmission of the radio signal; and a transmitter configured to transmit the radio signal by using the plurality of transmission antennas by the multi-antenna transmission mode notified to the user terminal. The controller reduces a number of transmission antennas to be used for the transmission of the radio signal so as to reduce power consumption of the base station. The controller maintains the multi-antenna transmission mode notified to the user terminal without changing the multi-antenna transmission mode, even when reducing the number of transmission antennas to be used for the transmission of the radio signal.

Abstract: A mobile communication system performs multi-antenna transmission by applying a pre coder matrix for determining transmission directionality. The mobile communication system comprises a user terminal that starts feedback of predetermined precoder matrix information to a node in response to an instruction from the node controlling communication. The predetermined precoder matrix information is used to decide the precoder matrix that is applied to transmission to another user terminal different from the user terminal. The user terminal comprises: a control unit that switches whether to stop the feedback after starting the feedback in response to the instruction.

Abstract: In a mobile communication system comprising a first user terminal and a second user terminal, D2D communication is radio communication directly performed between the first user terminal and the second user terminal in a frequency and a time assigned from a base station. In a time in which data is to be received from the first user terminal, when the second user terminal does not receive the data from the first user terminal, the second user terminal transmits failure notification indicating reception failure in the D2D communication to the base station.

Abstract: A sensor system may include a base, one or more wireless communication sensors attached to the base, and a wireless communication apparatus that performs wireless communication with the wireless communication sensors. The wireless communication sensors may include a sensor that detects a position of the wireless communication sensor, a wireless communication module that performs wireless communication with the wireless communication apparatus, and a controller that controls the sensor and the wireless communication module. The controller, when the position of the wireless communication sensor, detected by the sensor, satisfies a predetermined condition, may change a status of wireless communication between the wireless communication module and the wireless communication apparatus from a first state to a second state in which an electric power consumption of the wireless communication module is greater than in the first state.

Abstract: A communication control method used in a user equipment, user equipment, and apparatus for controlling a user equipment used in a user equipment perform early data transmission in which uplink user data is transmitted during a random access procedure. The user equipment receives from a base station, a first timer value for a random access procedure without the early data transmission and a second timer value for a random access procedure with the early data transmission, selects the second timer value in response to determining that the user equipment performs the early data transmission, and starts a timer configured with the second timer value in response to transmitting the uplink data by the early data transmission.

Abstract: A base station includes a controller that performs multicast service SC-PTM transmission, and a transmitter that transmits SC-PTM configuration information related to a configuration of the SC-PTM transmission via a SC-PTM control channel, which is a logical channel different from a MCCH, and transmits multicast data via a traffic channel for the SC-PTM transmission. Each of the SC-PTM control channel and the traffic channel is mapped on a DL-SCH. The transmitter transmits a SIB related to the SC-PTM control channel via a BCCH, transmits first resource allocation information for transmitting the SC-PTM configuration information via a PDCCH, where a predetermined RNTI for the SC-PTM control channel is applied to transmission of the first resource allocation information, and transmits second resource allocation information for transmitting multicast data by the SC-PTM transmission via the PDCCH. A G-RNTI different from the predetermined RNTI is applied to transmission of the second resource allocation information.
