Abstract
A technique for distributing channel allocation information in a demand access communication system. Multiple access codes are used that have a defined code repeat period or code epoch. For each such epoch duration, a schedule of assignment of traffic channels to active terminals for each epoch is determined. For each terminal designated as active during the epoch, a list of active channels for such terminal unit is assigned. Prior to the start of each epoch, a channel set up message is sent on one of the forward link channels, such as a paging channel, indicating the lists of active channels for epochs of the associated traffic channel(s) that are to follow.
