METHODS AND APPARATUS FOR CHANNEL QUALITY INDICATION FEEDBACK IN A COMMUNICATION SYSTEM

摘要

Methods and apparatus for feeding back channel quality indication in a communication system. First, a first channel quality indication index is determined in dependence upon a channel quality estimation of a first transmission channel, and a second channel quality indication index is determined in dependence upon a channel quality estimation of a second transmission channel. A differential channel quality indication index of the second channel quality indication index is determined with reference to the first channel quality indication index in dependence upon a differential compression scheme. Then, the first channel quality indication index and the differential channel quality indication index are reported.

1. A method for communication, the method comprising:
establishing a channel quality indication table, with the channel quality table comprising an index column comprising a plurality of channel quality indication indices and at least one column comprising a plurality of entries associated with corresponding channel quality indication indices; establishing a channel quality indication sub-table by selecting a subset of entries in the channel quality indication table; receiving, at a second node from a first node, a channel quality indication index within the channel quality indication sub-table; and looking up, at the second node, entries associated with the received channel quality indication index from the channel quality indication sub-table.
