Abstract
The present invention provides a method (400, 500, 600, 700, 800, 900, 1000) and device (1100, 1200, 1300) for contention for channel access to single-slot subscriber units that are capable of transmitting and receiving data on one time slot per TDMA frame, allowing contention for channel access on any one of the available packet time slots and transmission on the time slot where contention is won. Thus, the present invention eliminates a requirement for a subscriber unit to be assigned to a particular time slot for contention, thereby eliminating the problem of performing load balancing on the time slots.
