Abstract: A user terminal comprises a receiver configured to receive, configuration information configuring measurement for a queuing delay of data packet in an uplink, from a radio base station in a dedicated manner; a controller configured to perform the measurement; and a transmitter configured to report a result of the measurement to the radio base station per unit time. The configuration information includes information indicating length of the unit time and threshold information indicating a threshold related to the queuing delay. The controller is configured to perform the measurement per unit time. The transmitter is configured to report the result of the measurement upon measuring the queuing delay exceeding the threshold within the unit time. The transmitter is configured to not report the result of the measurement upon measuring the queuing delay not exceeding the threshold within the unit time.

Abstract: A user terminal, apparatus therefor, and method performed at a user terminal perform device-to-device (D2D) communication that is direct inter-terminal communication. The terminal stores preconfigured resource information and power information used to control the D2D communication, determines whether the user terminal is in out of coverage by not detecting at least one cell meeting a criterion based on a received power of radio signal, and determines to use the resource information and the power information stored in the storage in response to an out of coverage determination. The user terminal transmits data to other user terminal by the D2D communication based on both the resource information and the power information while the user terminal exists in the out of coverage.

Abstract: A user terminal according to one aspect executes a first and second DRX operations. The first DRX operation is an operation of discontinuously monitoring first control information, which is transmitted from the base station via PDCCH, using a C-RNTI that uniquely identifies the user terminal in a cell of the base station. The second DRX operation is an operation of discontinuously monitoring second control information, which is transmitted from the base station via the PDCCH, using a group RNTI assigned to a terminal group including the user terminal. The user terminal monitors the first control information in a first ON duration for the first DRX operation, and monitors the second control information in a second ON duration for the second DRX operation, the second ON duration being independent of the first ON duration.
