<p>A method of transferring data for one of a plurality of wireless remote stations of wireless telecommunication network, the one remote station (RS) comprising an RS-spread-spectrum transmitter and an RS-spread-spectrum receiver, the method comprising the steps of: receiving from a base station a broadcast common-synchronization channel comprising a frame timing signal at the RS-spread-spectrum receiver of the one RS; determining frame timing at the one RS from the received frame-timing signal; transmitting to the base station an access-burst signal from the RS-spread-spectrum transmitter of the one RS, the access-burst signal comprising a plurality of segments, each comprising a predefined preamble and a pilot signal, transmitting the segments at step-wise sequentially increasing power levels, the access burst signal starting at the beginning of an access slot, as defined by the frame timing; receiving from the base station an acknowledgment corresponding to the transmitted preamble at said RS-spread-spectrum receiver and ceasing transmission of the access burst signal in response thereto; and transmitting a spread-spectrum signal comprising any of data and power control information from said RS-spread-spectrum transmitter, in response to the receipt of the acknowledgment. <IMAGE>A method of transferring data for one of a plurality of wireless remote stations of wireless telecommunication network, the one remote station (RS) comprising an RS-spread-spectrum transmitter and an RS-spread-spectrum receiver, the method comprising the steps of: receiving from a base station a broadcast common-synchronization channel comprising a frame timing signal at the RS-spread-spectrum receiver of the one RS; determining frame timing at the one RS from the received frame-timing signal; transmitting to the base station an access-burst signal from the RS-spread-spectrum transmitter of the one RS, the access-burst signal comprising a plurality of segments, each comprising a predefined preamble and a pilot signal, transmitting the segments at step-wise sequentially increasing power levels, the access burst signal starting at the beginning of an access slot, as defined by the frame timing; receiving from the base station an acknowledgment corresponding to the transmitted preamble at said RS-spread-spectrum receiver and ceasing transmission of the access burst signal in response thereto; and transmitting a spread-spectrum signal comprising any of data and power control information from said RS-spread-spectrum transmitter, in response to the receipt of the acknowledgment. <IMAGE></p> |
