Abstract
A UE performs pilot measurements over a frequency sub-band of serving cell and adjacent cells based on pilot symbols for used in handover. UE uses channel quality measurement result to adjust frequency sub-band and periodicity of pilot measurement. In interference coordination scheme, UE is classified into cell edge or cell center UE based on channel quality measurement result. For downlink data reception, UE in cell edge is allocated cell edge frequency sub-band and UE in cell center is allocated with cell center frequency sub-band. If UE is in cell edge of the serving cell, UE also performs pilot measurement over cell edge frequency sub-band. If UE is in cell center, UE also performs pilot measurement over cell center frequency sub-band of the serving cell. When UE is located in cell edge, it performs measurement at a higher rate than when it is located in cell center.
