Title:
SYSTEM AND METHOD FOR EFFICIENT USAGE OF BROADCAST POWER WHILE MINIMIZING CO-CHANNEL CELL SITE INTERFERENCE
Document Type and Number:
WIPO Patent Application WO2000067394
Kind Code:
A3
Abstract:
A cell structure and associated method of cell and frequency planning are presented which reduce co-channel interference between nearby co-channel cell sites. The cell and frequency planning method involves the definition of a number of frequency channel sub-groups (SG) within each existing cell (10). Each frequency channel sub-group includes a number of frequency channels being broadcast at particular power levels ranging from low power to high power. During a mobile station call (360), the lowest, yet sufficient power level is used for the call (361). The cell sites are configured such that the frequency channel sub-groups being broadcast at the higher broadcast powers are transmitted at lower broadcast powers in nearby co-channel cell sites.
