摘要： A communication system and a method of communicating data. A first backhaul site can be dynamically selected from a plurality of backhaul sites that are each configured to wirelessly communicate with an access point. A controller can dynamically configure a transmission parameter used to communicate a first backhaul data stream between the access point and the first backhaul site. The first backhaul data stream can be derived from a source data stream and can be wirelessly communicated between the access point and the first backhaul site. A second backhaul site also can be selected. A second backhaul data stream also can be derived from the source data stream and wirelessly communicated between the access point and the second backhaul site. The first and second backhaul data streams can be combined.

摘要： A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.

摘要： Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

摘要： A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.
