Abstract
Abstract A system and method for a synchronized packet data communication system is described. Briefly control channels are transmitted in a reuse pattern defined by both frequency and timeslot division. Each timeslot division is such that different timeslot groups included in the repetition pattern are separated by at least one timeslot. No traffic data transmissions occur simultaneous to the control channel transmissions. Furthermore, a synchronization channel is introduced to be transmitted on the same physical channel as other packet common control channels.
