Pilot report based on interference indications in wireless communication systems

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.

主权项

1. A method for mitigating reverse link interference in a wireless communication environment, comprising:
monitoring reverse link interference at an affected base station caused by an access terminal served by a disparate base station; transmitting interference-overload indications as a function of the monitored reverse link interference to the access terminal served by the disparate base station to trigger the access terminal to report an overload condition to the disparate base station to cause the disparate base station to inhibit use of a reserved subset of resources for transmission by the access terminal in order to mitigate interference to the affected base station; scheduling at least one disparate access terminal served by the affected base station to transmit utilizing the reserved subset of resources; and explicitly indicating a condition of persistent and severe interference overload to the access terminal by utilizing at least one of a dedicated interference control channel, an embedded bit, and a bit employed for modulation or scrambling.
