Abstract:
1. A method for wireless communication, comprising: determining, at a first node, at least one reference subframe for determining channel state information (CSI) for a plurality of carriers having at least two different configurations, wherein the plurality of carriers comprise one of: at least one carrier configured for frequency division duplexing (FDD) aggregated with at least one other carrier configured for time division duplexing (TDD), or a first carrier having a first uplink-downlink configuration aggregated with a second carrier having a second uplink-downlink configuration; determining the CSI for the plurality of carriers based on the at least one reference subframe; reporting the CSI for the plurality of carriers to a second node, wherein the determining the at least one reference subframe comprises determining a single reference subframe for all of the plurality of carriers, and determining whether the reference subframe is a valid downlink subframe for each of the plurality of carriers.
