초록 ▼

A system for reducing receiver power consumption in communication system having a transmitter and one or more receivers schedules periodic messages in “slots.”Each receiver is assigned a slot during which it monitors the transmissions. The transmitter transmits messages to the receiver only during the assigned slots. The receiver is in an “active state”during its assigned slot. It may remain in the active state after its assigned slot if the message requires the receiver to perform additional actions. During the “inactive state,”which is the time period between successive occurrences of its assigned slot, the receiver may perform any action not requiring coordination with the transmitter. It may conserve power during this time by removing power from one or more components such as those used for monitoring the transmissions. At a time during the inactive state shortly before the assigned slot, the receiver applies power to these components and performs initializations. Such initializations may include requiring a pilot channel signal to which the receiver may synchronize itself if its timing signals have drifted out of synchronization with those of the transmitter during the preceding inactive state.

대표청구항 ▼

A method for conserving power in a cellular telephone having an average power consumption that is not currently involved in a telephone call by using periodic intervals of time, wherein each interval is comprised of a fixed number of time slots, and by scheduling communication from a base station to said cellular telephone during at least one time slot within each of said periodic intervals, comprising the steps of: identifying said cellular telephone to said base station; determining at said base station a set of active time slots within each interval wherein said set of active time slots comprises a quantity of time slots during which said base station may transmit messages to said cellular telephone; and reducing said average power consumption of said cellular telephone during said fixed number of time slots other than said set of active time slots.
