METHOD AND APPARATUS FOR INTERFERENCE MANAGEMENT IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method, comprising:
- identifying one or more priority parameters associated with a communication link and a designated set of resources for communication via the communication link;
constructing a resource utilization message (RUM), the RUM comprising a request for reduction of transmit power on the designated set of resources and a function of the one or more priority parameters; and
communicating the RUM to at least one interfering network node.

Abstract
Systems and methodologies are described herein that facilitate interference control and resource management in a wireless communication system. As described herein, a base station, terminal, and/or other entity in a wireless communication system that observes interference from one or more other network entities can construct and communicate resource utilization messages (RUMs) in order to request the interfering network entities to conduct power backoff on designated resources. Parameters constructed as a function of quality of service (QoS) and/or priority metrics (such as head-of-line delays, queue lengths, burst sizes, delay targets, average rates, or the like) can be included within the RUM, such that an entity receiving the RUM can compute QoS changes associated with various power backoff levels in order to select a power backoff level that maximizes overall system QoS performance.
