Abstract
A power management method and system is used with mobile terminals and base stations of a wireless communications system. A conventional random access channel downlink that provides information on whether the channel is available for use by a new mobile terminal is enhanced. While a first mobile terminal is establishing a connection with and transmitting a message to a base station, the base station repeatedly transmits a random access channel downlink that includes the number of units of time remaining in the current message transmission. A second mobile terminal wishing to establish communication with the base station receives and processes this information. Normally, the second mobile terminal would continuously monitor the channel until an idle indication is detected. However, by knowing the number of units of time remaining for the current message transmission, the second mobile terminal can conserve battery power by ceasing reception and processing of the downlinked slots until the specified time has expired.
