Abstract

This paper presents a channel sharing scheme, Neighbor Cell ChannelSharing (NCCS) , based on region partitioning of cell coverage for wirelesscellular networks. Each cell is divided into an inner-cell region and anouter-cell region. Cochannel interference is suppressed by limiting theusage of sharing channels in the inner-cell region. The channel sharingscheme achieves a traffic-adaptive channel assignment and does not requireany channel locking. Performance analysis shows that using the NCCS schemeleads to a lower call blocking probability and a better channel utilizationas compared with other previously proposed channel assignment schemes.
