Abstract:
Downlink rate adaptation in wireless communication systems are disclosed in which a UE reports RIs for both interference-free and interference-limited subframes. In general, the RI for the interference-free subframes will be higher than the RI reported for the interference-limited subframes. However, an eNB selects an RI and a transmission rate for interference-limited subframes based on what the UE can sustain instead of based only on the RI reported by the UE.
