  • Publication number: 20180176759
    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.

  • Publication number: 20180176840
    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.

  • Publication number: 20180175923
    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.
