    Abstract: There is provided a node for use in a network, the node comprising: communication circuitry to communicate with a management server. Bootstrap circuitry initially identifies an intermediate node from at least one available node in the network in response to the communication circuitry being unable to communicate with the management server directly. The communication circuitry is arranged to communicate with the management server indirectly via the intermediate node when unable to communicate with the management server directly. Role assignment circuitry assigns a role to be performed by the node in the network based on whether the communication circuitry communicates with the management server directly, or indirectly via an intermediate node.

    Abstract: A communications schedule routes data between relay nodes forming a wireless relay network and interconnects relay nodes by an ordered sequence of communications links established over a wireless resource comprising resource blocks. Candidate connectivity patterns for the ordered sequence of communications links and candidate resource allocations are provided. For each candidate connectivity pattern, a level of a performance characteristic is calculated for a selected combination of the candidate resource allocations. Based on a desired level of the performance characteristic, a candidate connectivity pattern and associated selected combination of candidate resource allocations whose calculated level of the performance characteristic meets the desired level, is selected as the communications schedule. In response to a trigger condition, the performance level evaluation process and the selection process are repeated to re-select one of the candidate connectivity patterns and its associated selected combination of candidate resource allocations to be used as the communications schedule.

    Abstract: A method and system are provided for determining modulation control information and a reference signal design to be used by a transmitter node when generating a transmit signal to transmit from a transmitter (logical antenna) of the transmitter node over a channel of a wireless link to a recipient node. The modulation control information is used by the transmitter node to convert source data into an information bearing signal, and the information bearing signal is combined with a reference signal conforming to the reference signal design in order to produce the transmit signal. The method comprises (a) selecting a candidate reference signal design from a plurality of candidate reference signal designs, (b) determining channel state information for the channel, (c) determining, from the channel state information, signal to noise ratio information for said channel, and (d) for each of a plurality of candidate modulation control information, using the signal to noise ratio information to determine a quality indication for said channel. Steps (a) to (d) are then repeated for each candidate reference signal design in said plurality. Thereafter a winning quality indication is selected from the determined quality indications, and the combination of candidate reference signal design and candidate modulation control information associated with the winning quality indication is then output to the transmitting node. By such an approach, quality indications can be established for each combination of possible reference signal design and possible modulation control information, and hence not only is the inherent channel estimation accuracy achievable using each possible reference signal design considered, but also the data transmission efficiency and robustness to channel effects of each possible modulation control information is also taken into account.

    Abstract: A communication apparatus, terminal apparatus, system and method are provided for performing wireless communication. The communication apparatus supports a plurality of component carriers, wherein one of the plurality of component carriers is designated as a current primary component and at least one of the plurality of component carriers is designated as a current secondary component carrier providing at least downlink communication. The communication apparatus comprises control circuitry for controlling a component carrier testing procedure for one or more component carriers. The testing procedure comprises, for each component carrier:establishing an uplink connection from the terminal apparatus to the communication apparatus using the component carrier; and determining a quality of the uplink connection for the component carrier. The control circuitry is responsive to completion of the testing procedure to designate an updated primary component carrier on the basis of the qualities of the uplink connections determined for the component carriers.

    Abstract: A cellular communication apparatus includes antenna circuitry. A transceiver receives or transmits a signal using the antenna circuitry on a chosen channel of a portion of a radio spectrum. The portion of the radio spectrum is divided into one or more channels including the chosen channel each occupying a bandwidth of the portion of the radio spectrum. Control circuitry dynamically changes a configuration of the one or more channels of the radio spectrum and communication circuitry communicates the configuration of the one or more channels of the radio spectrum to one or more items of user equipment.
