摘要： Techniques for combating high interference in a dominant interference scenario are described. A terminal may observe high interference from an interfering base station in a dominant interference scenario. In an aspect, high interference may be combated by reserving time intervals for a serving base station. The terminal may communicate with the serving base station in the reserved time intervals and may avoid high interference that may desensitize a receiver at the terminal. In one design, the terminal may measure received power of base stations and may report its interference condition. The serving base station may receive a report from the terminal, determine that the terminal is observing high interference, and send a reservation request to the interfering base station to reserve time intervals. The interfering base station may grant the request and return a response. The serving base station may thereafter communicate with the terminal in the reserved time intervals.

摘要： Systems and methodologies are described that facilitate employing interference-overload indications to generate pilot strength reports that can be leveraged to mitigate reverse link interference. An affected base station can send interference-overload indications when experiencing a strong interference/jamming scenario due to reverse link transmission by an offending access terminal. The offending access terminal can monitor interference-overload indications from the affected base station (e.g., although the affected base station can be excluded from an active set of the offending access terminal) and send a pilot strength report to a serving base station in response. The serving base station can receive the interference induced pilot strength report and command the offending access terminal not to transmit on certain channel resources (e.g., time, frequency, spatial, . . . ); thus, the affected base station can use these resources to schedule transmission(s) by access terminal(s) served thereby.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

摘要： Techniques for centralized control of peer-to-peer (P2P) communication and centralized control of femto cell operation are described. For centralized control of P2P communication, a designated network entity (e.g., a base station) may control P2P communication of stations (e.g., UEs) located within its coverage area. The designated network entity may receive an indication of a first station (e.g., a UE) desiring to communicate with a second station (e.g., another UE). The designated network entity may determine whether or not to select peer-to-peer communication for the first and second stations, e.g., based on the quality of their communication link. The designated network entity may assign resources to the stations if peer-to-peer communication is selected. For centralized control of femto cell operation, the designated network entity may control the operation of femto cells (e.g., may activate or deactivate femto cells) within its coverage area.
