Abstract
A base station with a defined geographic coverage area in a wireless communication system includes a base receiver, a base transmitter, and a base antenna array. The base antenna array has a base station beamformer arranged to produce (a) a broad antenna beam so that the base station can receive random access signals from subscriber stations at different locations within the coverage area and transmit beacon or acknowledgment signals to the subscriber stations at the different locations, and (b) a narrow antenna beam directed to an acknowledged subscriber station for receiving or transmitting data or traffic signals from or to the subscriber station. A subscriber station includes a subscriber receiver, a subscriber transmitter and a subscriber antenna. The subscriber transmitter is arranged to transmit signals to a system base station on one or more of a number of carriers having a defined frequency spacing within a given spectrum allotment. A first carrier corresponds to a random access channel on which the subscriber station requests access, and at least a second one of the carriers is selected for transmission of data or traffic from the subscriber to the base station.
