ABSTRACT:
Uplink time slots (108) may be allocated within a communication system (100) when a communication unit (102) transmits a first packet (501) to a time slot allocator (101). Upon receiving the first packet (501), the time slot allocator (101) determines whether the first packet (501) contains a request for allocation of N uplink time slots. When the first packet (501) contains the request for allocation of N uplink time slots, the time slot allocator (101) allocates the N uplink time slots to the communication unit (102) when the N uplink time slots are available, wherein the N uplink time slots are allocated contiguous in time. The time slot allocator (101) then transmits an allocation indication to the communication unit in each of N downlink time slots (110) corresponding to the N allocated uplink time slots (108) to inform the communication unit (102) of the allocation.
