摘要： Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

摘要： Methods and apparatus for reducing transmit emissions are described herein. The transmit out of band emissions in an adjacent band can be reduced while complying with existing wireless communication standards through utilization of one or more of reduced transmit bandwidth, transmit operating band offset, and channel index remapping. The transceiver can support a receive operating band substantially adjacent to a band edge. The transmit operating band can be offset from an adjacent frequency band, and can use a narrower operating band than is supported by the receiver. The transmit baseband signal can have a reduced bandwidth to reduce the amount of noise. The frequency offset can introduce a larger transition band between the transmit operating band edges and the adjacent frequency band of interest. The transceiver can remap channel assignments to compensate for the frequency offset such that the frequency offset introduced in the transmitter is transparent to channel allocation.

摘要： A base station can communicate resource allocation to a wireless mobile station in an uplink map information element. The base station can identify destination mobile stations using a shorthand connection identifier. The base station parses the connection identifier field into a shorthand connection identifier field and an embedded subfield data field. The shorthand connection identifier field can be sized to support a predetermined number of mobile stations. The base station can further parse the embedded subfield field into a number of sub-fields, each communicating a different set of control information. In one embodiment, the base station utilizes the embedded subfield to communicate power, timing, and frequency information to the destination mobile station.
