摘要： A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

摘要： An exemplary method of communicating includes using coordinated scheduling of downlink transmissions in a plurality of cells. The coordinated scheduling includes a serving node in one of the cells currently serving a mobile station pausing downlink transmission on at least one selected resource when a non-serving node in a neighboring one of the cells not currently serving the mobile station transmits a downlink communication intended for the mobile station on the selected resource.

摘要： An exemplary method of allocating bandwidth to a call for at least one user includes allocating 10 MHz of the bandwidth for a downlink between a base station and the at least one user. 5 MHz of the bandwidth are allocated for an uplink between the user and the base station. A selected amount of bandwidth is aggregated to the allocated 5 MHz for the uplink. The amount of bandwidth that is aggregated is at least one of an additional 3 MHz band or two additional 1.4 MHz bands.

摘要： An exemplary method of communicating includes shifting a constant-amplitude zero autocorrelation (CAZAC) root sequence to a shifted CAZAC sequence. The CAZAC root sequence is used by a source of a received communication. The shifted CAZAC sequence is used for detecting a preamble of the received communication.

摘要： The present invention provides a method and apparatus for using uplink reference signals for access grant requests. The method includes determining that at least one mobile unit is requesting access to at least one uplink channel based on information indicative of a change in a masking sequence applied to at least one reference signal. Another embodiment of the present invention includes providing a first reference signal modulated by a first masking sequence to indicate a request for access to at least one uplink channel.

摘要： A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.
