Abstract: A mobile communications system including: at least one base station configured to communicate data to/from different terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to camp-on to first and second carriers of plural carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronization signalling such that the first and second terminal devices both can synchronize with the first and second carriers to begin a camp-on procedure. Following synchronization with one of the first or second carriers to begin the camp-on procedure, the second terminal device is configured to determine whether or not to continue with the camp-on procedure in dependence on an aspect of physical layer signalling associated with a control channel of the carrier with which it has synchronized.

Also disclosed are corresponding methods and apparatus for transmission and reception of signals.

Abstract: A wired communications device configured to: receive a spread-spectrum timing-reference signal through a wired communications medium, from a second wired communications device; detect a code-phase of the received timing-reference signal; and transmit data to the second device through the wired communications medium, with a timing that is defined relative to the detected code-phase. Also provided is a master device configured to communicate with the wired communications device. The master device is configured to generate and transmit a spread-spectrum timing-reference signal to one or more first devices, through a wired communications medium and to receive, through the wired communications medium, data transmitted by the one or more first devices.

Abstract: A transceiver for full-duplex communication. The transceiver comprises: a transmitter and a receiver. The transmitter has a first oscillator circuit, for generating a transmit-carrier signal; and a first mixer, for up-converting a data signal to be transmitted by mixing it with the transmit-carrier signal, said data signal comprising a plurality of data symbols. The receiver has: a second oscillator circuit, for generating a receive-carrier signal; and a second mixer for down-converting a received signal by mixing it with the receive-carrier signal. The first oscillator and second oscillator are controlled such that there is a predetermined phase relationship between the transmit-carrier and receive-carrier signals at the start of each transmitted data symbol.

Abstract: Wirelessly communicating with a first type of terminal device and a second type of terminal device is disclosed. The first type of terminal device may have a host carrier having radio resource segments distributed in time. Each radio resource segment may provide radio resources across a first frequency band. A second type of terminal device may also communicate, within a second frequency band, using a subordinate carrier comprising resources that are a subset of the host carrier radio resource segments. The second frequency band may be narrower than and contained within the first frequency band.
