Method for Scheduling to Reduce Inter-Cell Interference for Voice Communication in OFDMA

摘要

A method schedules voice communication in an Orthogonal Frequency Division Multiplexing Access (OFDMA) network of base stations serving sets of mobile stations in cells. The method uses statistical characteristics of voice communications by adjusting scheduling periods accordingly to measurement reports provided by the mobile stations. The base stations generally use persistent scheduling for voice transmission due to inherent characteristics, along with extra signaling concerns. Base stations have the liberty of shortening or prolonging the scheduling period according to their needs while taking into account changes in dynamic conditions. This method makes use of the measurement reports provided by the mobile stations along with a shortened scheduling period in order to reduce ICI.
