METHOD AND SYSTEM FOR REDUCING FEEDBACK INFORMATION IN MULTICARRIER-BASED COMMUNICATION SYSTEMS BASED ON FREQUENCY GROUPING

摘要

Systems and methods for decreasing the amount of information sent on a feedback channel are disclosed. Various forms of spectral binning may be used to reduce the amount of information sent on the feedback channel. The systems and methods may be applicable to wideband communication systems, ultra -wideband communication systems, and/or other communication system using multiple carrier frequencies (e.g., tones). In one embodiment, a method of communication in a wireless communication system is provided. The method comprises obtaining a first set of channel condition data representative of a collective channel condition of a first plurality of carrier frequencies. At least one first carrier frequency is grouped in the first plurality of carrier frequencies based, at least in part, on at least one of a channel condition of the at least one first carrier frequency and the collective channel condition, the method further comprises communicating the first set of channel condition data from a receiver to a transmitter
