Abstract
Devices and methods which supplement a duplex frequency by providing one or more simplex frequencies and distributing a data load among them are provided. In one aspect, the system includes a server containing a scheduler in communication with a communications device. The server initially communicates with the communications device using a duplex channel, determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and one or more simplex channels. Before distributing the data, the server sends a schedule to the communications device via the duplex channel, so the communications device knows which bits of data are coming through which channels at which times. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.
