CQI estimation in a wireless communication network
First Claim
1. A method for wireless communication, comprising:
- receiving upper layer signaling identifying a first set of subframes and a second set of subframes;
determining a first channel quality indicator (CQI) based on at least one first subframe allocated to a serving base station and having reduced or no interference from at least one interfering base station, wherein the first set of subframes includes the first subframe; and
determining a second CQI based on at least one second subframe allocated to the at least one interfering base station, wherein the second set of subframes includes the second subframe.

Abstract
Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).
