Abstract: A holder may include a base, an antenna and a sensor. The base has a bar shape extended along a central axis from a first end toward a second end. The base may include a metal member and a first resin. The metal member may include a pocket that is attachable of an insert including a cutting edge. The first resin may be located closer to the second end than the metal member. The antenna may be covered with the first resin. The sensor may be located closer to the pocket than the antenna and may be wired connected to the antenna, and may be measurable a state of the base. This configuration may contribute to solving the problem that handling of wiring becomes complicated.

Abstract: A user equipment, apparatus, and method transmits a random access preamble to a cell and receives a message including a random access response as a response to the random access preamble from the cell. The message indicates that a Radio Resource Control (RRC) connection to the cell is rejected.

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 source eNB 200-1 manages at least a source cell in which a group comprised of UE 100-1 to UE 100-3 present. The source eNB 200-1 transmits one group handover command to the group, if the group is collectively handed over to a target cell. The one group handover command includes RRC configuration information for the UE 100-1 to UE 100-3.

Abstract: A transmission device (100) transmits transmission information to a reception device (200) via a radio channel. The transmission device (100) includes: a grouping unit (110) configured to divide the transmission information into a plurality of information groups; an error detection code adding unit (120) configured to add an error detection code to each of the plurality of information groups; and a transmission processing unit (140) configured to perform a process of transmitting the plurality of information groups to the reception device (200). The transmission processing unit (140) performs, for each information group included in the plurality of information groups, a transmission process by using a method having different error tolerance on the radio channel.

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.
