    摘要： A communication network element (536) comprises a transmitter (535) for transmitting at least one timing data packet to at least one further network element (524) over both a first communication link and a second communication link and a receiver (537) for receiving two timing data packets from the at least one further network element (524) over the second communication link. The communication network element (536) further comprises signal processing logic (538) operably coupled to the transmitter and receiver and arranged to calculate a transit delay of the at least one timing data packet over the first communication link based on the received two timing data packets from the at least one further network element (524) over the second communication link, wherein the signal processing logic (538) is capable of scheduling at least one transmission across the first communication link to the at least one further network element (524) in response thereto.

    摘要： A wireless subscriber communication unit comprises signal processing logic arranged to support a plurality of operational modes in a wireless communication system that comprises a plurality of communication networks. The signal processing logic is arranged to receive unicast communication in a home network that is associated with the wireless subscriber communication unit in a first mode of operation. The signal processing logic is arranged to receive broadcast communication from a second communication network that is not the home network in a second mode of operation such that the broadcast communications are adapted to appear to originate from the home network.

    摘要： A wireless serving communication unit comprises a signal processor, for receiving and processing a signal to be broadcast, and a number of transmitters operably coupled to the signal processor, for transmitting the broadcast signal in a plurality of sectorised cells to a wireless subscriber communication unit. The wireless serving communication unit comprises logic to replicate the processed signal into a plurality of replicated signals and logic introduce one or more delay(s) to one or more of the replicated processed signals, such that replicated broadcast signals having different delays are transmitted from a plurality of sectorised cells to one or more wireless subscriber communication unit.

    摘要： Embodiments of the invention provide a controller, in a cellular wireless network for cancellation of interference from neighboring cells. Logic in the controller determines channel quality of a radio channel between a first base station and a UE. Scheduling logic causes the first base station to adjust a number of data streams used for communication with the UE and a second base station to adjust a number of data streams used for communication to a second UE within a time period, as a function of the channel quality. Other embodiments provide an apparatus for reducing interference in a receiver that receives N data streams. Signal processing logic receives the N data streams, where N-M of the data streams represent interference with respect to M desired data streams, and cancels the N-M data streams so as to receive the M desired data streams. The N data streams may be received from multiple base stations, or multiple UEs.

    摘要： Aspects of the invention include a root node of a wireless communication infrastructure that buffers data packets for transmission by base stations over an air interface. The root node determines a time delay for transmission of a data packet from the root node to each base station, a maximum time delay of those time delays, and a timing latency based upon the maximum time delay. The root node transmits the timing latency to the base stations. In response, each base station initiates transmission of data packets received by the root node after expiration of the timing latency. Alternatively, the root node, instead of the base stations, may buffer the data packets, and transmit them so that they arrive at the base stations at substantially the same time.

    摘要： A cellular communication system comprises first and second serving communication units supporting respective first and second time division duplex (TDD) modes of operation on respective first and substantially frequency-adjacent second frequency channels comprising a plurality of uplink transmission resources divided into uplink timeslots and a plurality of downlink transmission resources divided into downlink timeslots. The first and second modes of TDD operation are dissimilar and communications cover substantially the same geographic area. The first serving communication unit transmits a plurality of idle periods in the first mode of operation arranged to encompass a time period used by the second serving communication unit for switching communication between downlink and uplink transmissions of the second mode of operation.
