Abstract: A radio terminal (1) selects, from a resource pool in a discovery period, NTX subframes for NTX times of transmission of a discovery signal in the discovery period based on a first value n1 of a resource value autonomously selected by the radio terminal (1) or a first value n1 of a parameter received from a base station (2). The NTX subframes selected based on the value n1 are selected so as to share at least one common subframe with NTX subframes selected based on a second value, different from the first value n1, and so as to include at least one subframe different from any of the NTX subframes selected based on the second value. It is thus, for example, possible to attenuate decline in reception quality of a discovery signal due to interference resulting from In-Band Emissions (IBE) when direct discovery of D2D communication is performed.
Abstract: Transmitter extracts CQI values representative of reception qualities measured by and transmitted from receivers as representing reception states of antennas of receivers, from data receivers and received by transmitter, combines the extracted CQI values depending on preset weighting coefficients, calculates resource coefficients for assigning resources for transmitting data to receivers from the combined CQI values, and assigns resources for transmitting data to receivers based on the calculated resource coefficients.
Abstract: Radio base stations connect by radio lines with radio terminals in cells that make up each radio base station and relay data communication realized by the radio terminals on bearers on radio lines. Base station controllers record correspondence information of the data flow of data communication with the radio terminals and the bearers on the radio lines and, by referring to the correspondence information, effects termination of data communication with the radio terminals. When, in a state in which a drift base station controller relays and transfers data communication between radio base stations to which the radio terminals are connected and a serving base station controller, the serving base station controller is transferred to the drift base station controller, the plurality of base station controllers then report to the drift base station controller the correspondence information from the serving base station controller.

Abstract: A communication system is disclosed in which coordinated multi-point transmissions for a mobile device are carried out in two stages. In the first stage, a central controller obtains Channel State Information (CSI) reports from multiple transmission points, based on which the controller estimates respective data rates for transmissions between each transmission point and the mobile device. The controller determines an active set of transmission points to be associated with the mobile device, and informs the transmission points about the association made. In the second stage, the transmission points included in the active set carry out scheduling for the mobile device independently from each other until the controller updates the active set of transmission points.
