Abstract

In a wireless communication system, wireless channels are maintained for communication between users and the base station. Often, a wireless user may be switched on, but not actively sending or receiving data. Accordingly, wireless users may be “active,” and currently allocated a wireless traffic channel for sending or receiving, or “idle,” and not currently sending or receiving. A wireless user may be maintained in an idle state through a periodic sequence of synchronization messages. A method for controlling a power level of a wireless message includes determining the presence of data to be transmitted, and adjusting the power level of the synchronization message depending on the presence of data. The synchronization messages corresponding to the idle state employ a lower power level than the active state transmissions which employ a higher power level. The system therefore controls the power accordingly such that synchronization messages are sent at a lower power level when no data is present, thereby reducing power consumption and interference.
