Abstract:
1. A method for communication in a wireless system comprising: receiving, by a communication device from a base station, an indication that a ranging code-space includes at least a first group and a second group, wherein a first maximum allocation in response to an allocation request associated with the first group is smaller than a second maximum allocation in response to an allocation request associated with the second group; transmitting by the communication device a first message including a ranging code selected from one of the first group and the second group; receiving by the communication device an uplink information element including an allocation information element and a sub-burst information element associated with the ranging code; if a duration bit in the allocation information element is greater than zero, transmitting a bandwidth request header according to a legacy protocol; and if the duration bit in the allocation information element is set to zero, transmitting a second message using the ranging code and according to a temporary identifier in the sub-burst-information element.
