Patent ID: RE42573

Claim:
A method for reporting channel quality by an MSS (Mobile Subscriber Station) in a communication system, comprising the steps of: a) receiving, from an active BS (Base Station) channel quality measurement information needed for an MSS to measure channel qualities of the active BS and a plurality of neighbor BSs, and receiving channel quality report information defining a report mode needed for the MSS to report the channel qualities of the measured channel qualities of the active BS and the neighbor BSs; b) measuring channel qualities of the active BS and the neighbor BSs according to the channel quality measurement information; and c) reporting the measured channel qualities of the active BS and the neighbor BSs to the active BS according to the channel quality report information, wherein the report mode is one of a plurality of report modes, and the plurality of report modes includes a first report mode and a second report mode, wherein the first report mode and the second report mode include information on the a time at which the measured channel qualities of the active BS and the neighbor BSs are reported, wherein the channel quality report time of the first report mode is a predetermined setup period a period indicated in the channel quality report information , wherein the channel quality report time of the second report mode identifies a specific time at which a magnitude order of SINRs (Signal to Interference and Noise Ratios) of individual reference channel signals measured at step (b) is different from other a magnitude orders order of SINRs of reference channel signals of the active BS and the neighbor BSs measured previously , and wherein the channel quality measurement information includes a measurement start time at which a channel quality measurement operation begins, and a measurement duration for executing the channel quality measurement operation during which the channel quality measurement operation is carried out .
