    Abstract: A cellular wireless internet access system which operates in the 2.5 to 2.68 GHz band and which must comply with complex government regulations on power levels, subscriber equipment and interference levels yet which provides high data rates to users and cell sizes of 1½ miles radius or more from base stations with subscriber equipment and antennas mounted indoors. Such base stations are mounted low and use spread-spectrum transmission to comply with interference rules with respect to adjacent license areas. An unidirectional tear-drop coverage pattern is used at multiple cells to further reduce interference when required. Time division duplex is used to allow the system to operate on any single channel of varying bandwidth within the 2.5 to 2.68 GHz band. Backhaul transmission from base stations to the Internet is provided using base station radio equipment, operating either on a different frequency in the band or on the same frequency using a time-division peer-to-peer technique. Different effective data-rates are provided by a prioritization tiering technique.

    Abstract: A method for supporting cross carrier indication of a control channel change notification in a wireless communication system that provides broadcast services on a plurality of carriers. The method includes, at a base station: receiving a first message including an indication of a control channel change requirement; mapping at least one single broadcast service to a plurality of component carriers; generating a second message including a control channel change notification for the broadcast service based on the mapping; and transmitting the second message on at least one component carrier to at least one wireless communication unit.

    Abstract: An Orthogonal Frequency Division Multiplex (OFDM) communication system comprises OFDM transmitters and an OFDM receiver. The system comprises a subcarrier status data controller for transmitting subcarrier status data to the OFDM receiver. The subcarrier status data indicates the active subcarriers of the OFDM transmitters. The OFDM receiver comprises a receiver which receives a signal comprising a desired signal component from a first OFDM transmitter and interference from at least one interfering OFDM transmitter. The OFDM receiver further comprises a subcarrier status processor which receives the subcarrier status data and a channel estimator which determines channel estimates for at least an air interface communication channel from the first OFDM transmitter and an air interface communication channel from the interfering OFDM transmitter. An interference mitigation processor performs interference mitigation of the interference in response to the subcarrier status data and the channel estimates.
