Title:
METHOD AND APPARATUS FOR REVERSE LINK LOADING ESTIMATION
Document Type and Number:
WIPO Patent Application WO2000033475
Kind Code:
A3
Abstract:
In a wireless communication system, in order to determine a level of loading, the system enters a period of silence during which a designated remote unit (42) continues to transmit but other remote unit transmissions are interrupted. The base station (40) and designated remote unit (42) perform closed loop power control on a reverse link signal received from the designated remote. A first series of power control commands accumulated and a first corresponding transmit gain adjustment value is stored. Normal operation is resumed. Once again, the base station (40) and designated remote unit perform closed loop power control on the reverse link signal received from the designated remote unit (42). A second series of power control commands are accumulated and a second corresponding transmit gain adjustment value is stored. A level of loading is determined based upon the first and second transmit gain adjustment values.
