Abstract: A radio terminal performs radio communication with a base station in a mobile communication system. The radio terminal includes a controller configured to perform processing of transmitting an aperiodic CSI feedback related to a downlink channel state to the base station. In response to a predetermined condition being satisfied, the controller performs multiplex transmission in which uplink data in which the aperiodic CSI feedback is multiplexed is transmitted to the base station, by using a PUSCH resource.

Abstract: A method, user equipment and chipset is used for a first user equipment (UE) having a codec in which at least one of encoding audio or video data and decoding of the audio or video data is performed. A first bit rate is acquired for the codec from a second user equipment that is a communication partner of the first user equipment, a base station a message is transmitted to a base station for checking whether the first bit rate can be provided by a base station. The message includes information indicating the first bit rate.

Abstract: A user equipment, method, and apparatus for controlling user equipment receive, from a base station included in a network, a radio resource control (RRC) release message that causes the user equipment to transition to an RRC inactive state in which context information of the user equipment is maintained in the network. The RRC inactive state is a different state from an RRC connected state and an RRC idle state, and the RRC release message includes information indicating a value of a timer used for performing an RRC resume procedure. The timer is started upon receiving the RRC release massage, and the RRC resume procedure is performed when the timer expires.

Abstract: A user equipment, apparatus and method comprise starting reception from a base station from a second slot out of a first slot and the second slot which configure a subframe, determining a first modulation order used for downlink control information transmitted in the second slot, and starting the reception from the second slot by using the first modulation order. The downlink control information is a PDCCH or an EPDCCH.

Abstract: A radio terminal according to one embodiment comprises a controller configured to perform a codec adaptation based on assistance or control by a base station. The controller measures a radio quality parameter of the downlink. The controller, in a procedure for establishing a connection with the base station, transmits, to the base station, a predetermined message including the radio quality parameter.

Abstract: A base station according to an embodiment includes a controller configured to perform a process of transmitting, in a specific frequency band shared by a plurality of operators and/or a plurality of communication systems, a burst signal including data or a control signal and a discovery reference signal including a reference signal and/or a synchronization signal. If there is a transmission duration of the discovery signal within a transmission duration of the burst signal after starting the transmission of the burst signal, the controller performs a process of transmitting the discovery reference signal even within the transmission duration of the burst signal.

Abstract: A communication control method, user equipment and apparatus thereof include transmitting, to a base station by a user equipment, first information on a priority of a data pack to be transmitted from the user equipment via direct communication in which the data packet is transmitted to another user equipment without passing through the base station. The first information assists the base station in scheduling transmission resources for the direct communication. The method, user equipment and apparatus also include transmitting a request for requesting transmission resources for the direct communication to the base station by the user equipment, and receiving by the user equipment from the base station second information indicating transmission resources for the direct communication scheduled by the base station.

Abstract: A UE (100) receives a handover command from a source cell to perform a handover to a target cell in response to the handover command. The handover command includes a notification indicating omitting a random access procedure during the handover. The UE (100) omits, in response to the notification, the random access procedure during the handover.
