摘要： In a user equipment, base station and method for a mobile communication system, the user equipment receives, from a first base station, transmission power control information used for a dual simultaneous transmission in which radio signals are simultaneously transmitted to both the first base station and a second base station, and determines a first transmission power and a second transmission power for the dual simultaneous transmission based on the transmission power control information. The first transmission power is used for transmitting a radio signal to the first base station, and the second transmission power is used for transmitting a radio signal to the second base station.

摘要： A radio terminal according to one embodiment comprises a controller configured to transmit a physical uplink shared channel to a base station by an interlace mapping using a plurality of resource blocks distributed on a frequency axis while overlapping on a time axis. The controller receives, from the base station, control channel information on a time-frequency resource used for transmitting the physical uplink control channel. The controller stops transmission in a specific resource block corresponding to the time-frequency resource from among the plurality of resource blocks, based on the control channel information.

摘要： A radio terminal according to one embodiment comprises: a controller configured to perform a process of: receiving, if the radio terminal is in a specific state different from an RRC connected state, multicast/broadcast data transmitted from a base station; and transmitting feedback information on the multicast/broadcast data to the base station. The controller is configured to autonomously determine a transmission parameter to be used for transmitting the feedback information and transmits the feedback information by using the determined transmission parameter.

摘要： A base station and method thereof includes transmitting from the base station to a user equipment, parameters for an offload from the cellular RAN to a wireless local area network (LAN). The parameters are used by the user equipment to perform an access network selection between the cellular RAN and the wireless LAN, and include a first threshold for comparison with a cellular signal strength of the cellular RAN, a second threshold for comparison with a wireless LAN signal strength of the wireless LAN, and a third threshold for comparison with a load of the wireless LAN. When performing access network selection, the parameters may cause the user equipment to perform the offload, in response to the cellular signal strength being lower than the first threshold, the wireless LAN signal strength being higher than the second threshold, and the load of the wireless LAN being lower than the third threshold.

摘要： A base station according to one embodiment comprises a controller configured to perform a downlink transmission process using a subframe. The subframe comprises a main PDCCH (Physical Downlink Control Channel) region located at a head portion of the subframe, and a data region other than the main PDCCH region. The data region comprises a short TTI region to which a short TTI (Transmission Time Interval) having a shorter time length than the subframe is applied. The short TTI region comprises a sub-PDCCH region. The controller is configured to arrange information indicating the sub-PDCCH region in the main PDCCH region.

摘要： A communication method according to an embodiment includes transmitting first information for causing a user terminal to hold context information of the user terminal from a network to the user terminal in a radio resource control (RRC) connected state. The context information includes a cell-radio network temporary identifier (C-RNTI) allocated to the user terminal. The user terminal holds the context information without discarding the context information, based on the first information, even if the user terminal transitions from the RRC connected state.

摘要： A radio terminal according to one embodiment comprises a controller configured to perform radio communication in a time division duplex system, with a base station. The controller is configured to receive a downlink radio signal from the base station; and transmit to the base station, response information indicating whether reception of the downlink radio signal is successful, wherein the response information is transmitted by using an uplink radio resource different from an uplink control channel resource even if the uplink radio resource is not allocated for data transmission from the base station.
