摘要： A wireless feeder network comprises feeder base stations coupled to the communications network and feeder terminals coupled to associated access base stations of the access network. A group of wireless network components form elements of a feeder cluster and the elements of the feeder cluster are connected by an additional communications resource configured to be operated in parallel with the wireless resource of the wireless feeder network. Both a primary and secondary element of the feeder cluster seek to decode at least one resource block allocated to the primary element for reception of data. Information derived from the secondary decoded data is transmitted from the secondary element to the primary element via the additional communications resource. The primary element then performs a revised decoding process additionally using the information received from said secondary element to improve its own decode probability.

摘要： An apparatus and method are provided for controlling a wireless feeder network used to couple access base stations of an access network with a communications network. The wireless feeder network comprises a plurality of feeder base stations coupled to the communications network and a plurality of feeder terminals coupled to associated access base stations. Each feeder terminal has a feeder link with a feeder base station, and the feeder links are established over a wireless resource comprising a plurality of resource blocks. Sounding data obtained from the wireless feeder network is used to compute an initial global schedule to allocate to each feeder link at least one resource block, and the global schedule is distributed whereafter the wireless feeder network operates in accordance with the currently distributed global schedule to pass traffic between the communications network and the access base stations. Using traffic reports received during use, an evolutionary algorithm is applied to modify the global schedule, with the resultant updated global schedule then being distributed for use. This enables the allocation of resource blocks to individual feeder links to be varied over time taking account of traffic within the wireless feeder network, thereby improving spectral efficiency.

摘要： 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.

摘要： A point to multipoint device for use in a wireless network to provide wireless communication with a plurality of telecommunications units is described. For communication from the telecommunications units to the point to multipoint device, the point to multipoint device is operable to define a sequence of variable duration communication channels, each communication channel being allocatable to one of the telecommunications units. The point to multipoint device has training sequence storage for storing a training sequence indication indicating a training sequence associated with the point to multipoint device. Repetition rate storage is also provided for storing a repetition rate at which the training sequence is to be repeated in the sequence of communication channels, the repetition rate being the same for all point to multipoint devices in the wireless network. An interface receives a synchronisation signal issued to all point to multipoint devices in the wireless network, with the synchronisation signal being used to determine a time at which a first occurrence of the training sequence is to occur within the sequence of communication channels. Communication channel control logic defines the sequence of variable duration communication channels and causes control data to be transmitted to the telecommunications units identifying the sequence of channels, the training sequence indication and the repetition rate. An antenna array provides a reception beam for receiving the communication from the telecommunications units, and beamforming logic is used to determine beamforming weights used to produce the reception beam. The beamforming logic repeats the determination of beamforming weights at the repetition rate coincident with the appearance of the training sequence in the sequence of communication channels. This provides a particularly effective technique for reducing co-channel interference within the wireless network.

摘要： An apparatus and method are provided for controlling a wireless feeder network which connects access base stations to a communications network. The wireless feeder network comprises a plurality of feeder base stations connected to the communications network and a plurality of feeder terminals connected to the plurality of access base stations. A sounding schedule is determined for the wireless feeder network in dependence on a visibility matrix, the visibility matrix indicative of visibility via the wireless feeder network between each of the plurality of feeder base stations and each of the plurality of feeder terminals. Then a sounding procedure within the wireless feeder network is controlled in accordance with the sounding schedule. The visibility matrix enables a coordinated sounding procedure to be carried out, allowing more accurate channel metrics for the wireless channels of the network to be determined which are not adversely affected by interference between elements of the network.

摘要： A point to multipoint device for use in a wireless network to provide wireless communication with a plurality of telecommunications units is described, for communication from the point to multipoint device to the telecommunications units, the point to multipoint device being operable to employ multiple sets of beams, at any point in time one set being used. The point to multipoint device comprises beam set generation logic for generating the multiple sets of beams arranged into one or more groups, each group comprising one beam from each set. Within each group the beams of that group are orthogonal with respect to each other, and each beam within each set is generated randomly with respect to other beams in that set. An interface is provided for receiving a synchronisation signal issued to all point to multipoint devices in the wireless network. Beam switching logic is then used to determine, having regard to the synchronisation signal, switch times at which the point to multipoint device switches from one set of beams to another set of beams, the switch times being the same for all point to multipoint devices in the wireless network. An antenna array is controlled by the beam switching logic to produce at any point in time one of the sets of beams for transmitting data forming the communication to the telecommunications units. The use of such sets of beams has been found to lower the average co-channel interference observed within the wireless network.
