Patent ID: 8744494

Claim:
In a satellite based wireless communication system, a method for establishing communication links comprising: establishing a forward link from the satellite to a plurality of subscriber wireless communication devices (WCDs) by use of a shared frequency multiuser communication protocol; applying error correction coding to the forward link, using an aggregation of communications associated with the plurality of subscriber WCDs to provide an error correction code based on the aggregation of communications; receiving communications in a return link signal by use of a protocol providing channels having dedicated frequency assignments and non-slotted channel assignments; receiving access probes from WCDs on an access channel in a return link; transmitting forward signals in accordance with a CDMA communication protocol generally described by the 1xEv-DO communication standard; receiving, as transmissions in the return link, dedicated narrowband channels for traffic and at least one of wideband CDMA communication or narrowband ALOHA type communication as an access probe; and providing, as transmissions in the forward link, a slotted scheme whereby multiple user data are multiplexed and sent on a wide bandwidth.
