Patent ID: 8553585

Claim:
A Mobile Subscriber Station (MSS) in a communication system, comprising: a receiver for receiving, from an active Base Station (BS), channel quality measurement information for the MSS to measure channel qualities of the active BS and a plurality of neighbor BSs, and channel quality report information defining a report mode for the MSS to report measured channel qualities of the active BS and the plurality of neighbor BSs; a processor for measuring the channel qualities of the active BS and the plurality of neighbor BSs according to the channel quality measurement information; and a transmitter for reporting the measured channel qualities of the active BS and the plurality of neighbor BSs to the active BS according to the channel quality report information, wherein the report mode includes one of a first report mode and a second report mode, wherein the first report mode and the second report mode include information on a time at which the measured channel qualities of the active BS and the plurality of neighbor BSs are reported, wherein the channel quality report time of the first report mode includes 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 Signal to Interference and Noise Ratios (SINRs) of individual reference channel signals measured is different from a magnitude order of SINRs of reference channel signals of the active BS and the plurality of neighbor BSs previously measured, 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.
