  • Method and apparatus for provision of non-power control information through a power control channel to a mobile station
    Patent number: 7054656
    Abstract: Using conventional techniques, a common power control channel provides information used by mobile stations for power control operation of each mobile station. In accordance with the present invention, the common power control channel is also used to provide information used by the mobile stations for purposes other than the power control operation of each mobile station. In one embodiment, the information used for purposes other than power control operation comprises information instruction the mobile station to transition to an active state. In another embodiment, the information used for non-power control purposes is transmitted to mobile stations during periods in which the power control information is not being transmitted. Using a common power control channel in this manner substantially reduces the resources consumed by a mobile station while operating in a stand-by state.
