Abstract
A method of determining the position of the split between uplink and downlink bandwidth, in a point of multipoint radio access system with time division duplex scheme comprising a certain number of user terminals and a base station has been disclosed, wherein there are at least two quality of service classes, a first class for guaranteed services (RT) and a second class for not-guaranteed/best effort services (BE). The MAC layer evaluates and controls a further movement of the split—as that initially determined by a Call Admission Control (CAC)—according to the behavior of uplink and downlink not-guaranteed/best effort queues observed during a certain observation period.
