Abstract: Schemes for supporting device-to-device, D2D, communications between terminal devices in a wireless telecommunication system. A network entity, e.g. a base station, establishes a set pool of radio resources to be reserved for use for D2D communications and communicates an indication of these resources to terminal devices. On an ongoing basis the network entity monitors the extent to which the set of radio resources reserved for D2D communications is being used, for example based on feedback received from terminal devices or its own measurements. If it is determined the set of radio resources reserved for D2D communications is being under-utilized or over-utilized, the network entity may establish an updated set of radio resources to be used for D2D communications, and communicate this to the terminal devices. Thus a mechanism is provided for dynamically adjusting the size of a set of resources available for D2D communications in response to changing resource utilization.

Abstract: A communications system including an infrastructure equipment, forming part of a mobile communications network, that transmits and receives data to/from a user device via a wireless access interface using a plurality of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers that extend across a first bandwidth. The infrastructure equipment is configured to transmit repeatedly signals representing a same instance of user device payload data in a second bandwidth less than and within a first bandwidth, and includes a subset of the OFDM subcarriers. The user device is configured to receive one or more of the signals repeatedly transmitted across the second bandwidth, to store in a memory signals representing the repeatedly transmitted signals received across the second bandwidth and to combine the stored signals, and to detect the user device payload data from the combined signals, the user device having been provided with an indication of the second bandwidth.

Abstract: Provided is a method for performing a handover from a first base station to a second base station by a user equipment that is performing a radio communication over a communication channel formed by aggregating a plurality of component carriers. The method includes a step of transmitting a handover command for a component carrier for which a handover has been approved by the second base station among the plurality of component carriers from the first base station to the user equipment and a step of trying to make an access from the user equipment to the second base station for each component carrier in response to the handover command.

Abstract: A communications device includes: a receiver configured to receive signals including at least one positioning reference signal transmitted in each of a plurality of time units, at least one antenna connected to the receiver; a motion detector configured to determine a relative local position of the communications device; and a controller configured to generate a measurement data set including plural measurement samples of at least a phase of the positioning reference signal according to a sampling rate, and a location of the communications device at which the phase of the positioning reference signal was determined. The controller is configured to estimate a relative angle of arrival of the received radio signals, used to determine an estimation of a location of the communications device, wherein the controller is configured to adapt at the rate of sampling to generate the measurement data set in accordance with predetermined conditions.

Abstract: An electronic device that determines a first parameter corresponding to a length or duration of data to be transmitted by the electronic device; determines whether the first parameter exceeds a predetermined threshold value; controls a wireless interface of the electronic device to transmit a request to send the data when the parameter exceeds the predetermined threshold value; acquires a second parameter related to detection sensitivity or transmission power; and determines, when the first parameter does not exceed the predetermined threshold value, whether to transmit the request to send the data prior to transmitting the data based on the second parameter.

Abstract: To improve utilization efficiency of media by an information processing apparatus in a situation where a plurality of networks is adjacent to each other.An information processing apparatus includes: a measuring unit; a judging unit; and a control unit. In the information processing apparatus, the measuring unit measures signal strength of a received signal. The judging unit judges whether or not later signal transmission is possible using a relative value with respect to the signal strength measured by the measuring unit as a threshold on the basis of the threshold. The control unit controls signal transmission in accordance with the judgment by the judging unit about whether or not signal transmission is possible.

Abstract: An information processing apparatus includes a control part. The control part performs control to transmit a frame for requesting the transmission of data to an information processing apparatus as a destination of the data and for requesting information processing apparatuses other than the information processing apparatus as the destination to set a transmission inhibition time, the frame being transmitted with transmitting power determined on the basis of surrounding environment information regarding an environment surrounding the information processing apparatus transmitting the frame. Transmission of the frame causes the transmission inhibition time to be set over an appropriate range of information processing apparatuses. Efficiency of utilization of communication resources is improved by suitably setting a transmission inhibition time.
