Abstract: Improvement of use efficiency of radio resources is realizable.An information processing device is an information processing device which includes a reception unit and a control unit. The reception unit included in this information processing device is a reception unit which receives a packet. In addition, the control unit included in the information processing device is a control unit which controls a packet monitoring state of the information processing device in case of detection of reception of a packet not addressed to the information processing device. The packet monitoring state is controlled on the basis of reception power at the time of reception of the packet not addressed to the information processing device.

Abstract: A wireless telecommunications system in which downlink communications are made using a radio interface that spans a system frequency bandwidth (host carrier) and supports at least some communications from a base station to least some terminal devices within a plurality of restricted frequency bands (virtual carriers) which are narrower than and within the system frequency bandwidth. A terminal device conveys an indication of its identity, e.g. an IMSI, to the base station during an initial connection procedure as the terminal device seeks to access the radio interface. The terminal device and the base station both determine a selected restricted frequency band from among the plurality of restricted frequency bands based on the identity of the terminal device in the same way. Thus the terminal device and the base station select the same restricted frequency band and can accordingly configure their respective transceivers to allow for downlink communications between them within the selected restricted frequency band.

Abstract: A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first reduced bandwidth carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second reduced bandwidth carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.

Abstract: A communications device comprising a transmitter, a receiver and a controller operable to transmit and to receive signals representing data to and from a network element across a first wireless access interface, the first wireless access interface being provided by the network element and access to resources of the first wireless access interface being controlled by the network element. The controller is configured to control the receiver to perform detection of signals transmitted across a second wireless access interface, and to control the transmitter to transmit a reporting message to the network element across the first wireless access interface, the reporting message including an indication of one or more properties of signals that have been detected across the second wireless access interface.

Abstract: Frames in a variable length frame format which are addressed to a plurality of users are multiplexed and preferably transmitted. Data frames having different lengths are multiplexed on a same time through space division multiple access, but since the multiplexed frames are transmitted while eventually having a same length, when the multiplexed data frames from the access point STA0 are received in the respective communication stations STA1 to STA3 in FIG. 4 or when data simultaneously transmitted from the respective communication stations STA1 to STA3 are received in the access point STA0 in FIG. 5, it is possible to eliminate an operation instability of AGC.

Abstract: A mobile communications system includes a wireless access interface communicating data to/from mobile communications devices, the wireless access interface provided on a downlink first carrier, the first carrier providing plural communications resource elements across a first frequency range, and within a second frequency range within and smaller than the first frequency range. The wireless access interface includes plural time divided sub-frames each including the plural communications resource elements of the first and second frequency ranges, each sub-frame including a first wideband control channel in a part having a bandwidth corresponding substantially to the first frequency range, and a second narrow band control channel in a second part. The second narrow band control channel can communicate control information to first and second mobile communications devices and forms part of plural communications resource elements of the second frequency range, to make more use of the communications resources available to the communications system.
