Abstract

Channel borrowing without locking (CBWL) is a family of channel sharing schemes for cellular communication systems. They allow real-time borrowing of channels from adjacent cells without the need for channel locking in cochannel cells. In this paper, an analysis of cochannel interference for CBWL schemes in sectorized cellular systems is presented. Two typical configurations are analyzed. One has 120° directional antennas and a reuse factor of seven. The other has 60° directional antennas and a reuse factor of four. The analysis shows that CBWL can significantly enhance the traffic capacity of sectorized cellular systems at the cost of a slight increase of cochannel interference in comparison with the corresponding sectorized scheme and no borrowing
