Abstract:
1. A method for processing communication signals, the method comprising: assigning a bandwidth and a feedback period to one or more Channel Quality Indicator (CQI) reporting units and a bandwidth and a feedback period to one or more Pre-coding Matrix Index (PMI) reporting units; dynamically adjusting sub-divisions in at least one of time or frequency corresponding to said bandwidth and said feedback period assigned to said one or more CQI reporting units and said bandwidth and said feedback period assigned to said one or more PMI reporting units based at least on a first uplink channel state information corresponding to said bandwidth and said feedback period assigned to said one or more CQI reporting units and to said bandwidth and said feedback period assigned to said one or more PMI reporting units; generating one or more feedback messages based at least on a second uplink channel state information over said adjusted sub-divisions in at least one of time or frequency corresponding to said bandwidth and said feedback period assigned to said one or more CQI reporting units and to said bandwidth and said feedback period assigned to said one or more PMI reporting units; and applying a differential scheme to said one or more feedback messages to reduce a number of bits required for said one or more feedback messages.
