System for improved power savings during full DTX mode of operation in the downlink
Abstract
A system and method that achieve power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full DTX. When full DTX is detected by reception of a Special Burst (SB), the receiver is turned off for all timeslots and frames for the duration of the Special Burst Scheduling Period (SBSP). The transmitter schedules transmissions following any idle period to start on the boundary of the SBSP. The receiver determines the SBSP and if the transmitter initiates transmissions according to SBSP by reception of several initial full DTX cycles.
