Forward Link Power Control for CDMA Cellular Systems

摘要

This paper aims at developing forward link power control methods for CDMA cellular systems. The pur- pose is to allocate available power to as many mobiles as possi- ble. When a power allocation in the network is fixed, the power assigned to the cell where rare mobiles communicate is wasting, and moreover, is prohibitive if other cells fall short of transmit- ting power. In this case, re-allocation is necessary. Power control in this paper takes the form of allocating pilot and traffic power according to the different needs from each cell.
