ABSTRACT:
A method used in a communication system (10) having central controllers (14) in communication with a plurality of user devices (12) where synchronizing data (34) and user data (35) are transmitted for a predetermined period of time defining a dwell (30). The method for delivering data to more than one user device (12) simultaneously includes the steps of providing an indicator (34) associated with at least a portion of a dwell indicating that the transmission of user data (35) is directed towards more than one user device (12), and informing the user devices of the repetition rate at which the indicator is transmitted. The user device schedules periods of time during which it is enabled and disabled respectively, based upon the repetition rate of the indicator received such that the user device is enabled and receives the data directed towards more than one user device.
