ABSTRACT:
To enable point-to-multipoint communication services in an existing cellular communication system infrastructure, each member subscriber station, i.e., a subscriber station participating in such a service, is receiving a forward link shared channel, and in certain embodiments additionally a forward link dedicated channel. Because transmission on the forward link channels from neighboring sectors presents interference to the transmission from the sector serving the subscriber station, it is desirable to control the forward link channel transmission power to the minimum acceptable power. Additionally, a transmission form each member subscriber station on a reverse link channel presents interference to other subscriber stations. Therefore, it is desirable to control the reverse link channel transmission to the minimum signal level. Consequently, a method and apparatus for a power control that enables point-to-multipoint services in an existing infrastructure of a wireless cellular telephone system is disclosed.
