"METHOD OF SUBMITTING DATA IN A MULTIPLE ACCESS COMMUNICATION SYSTEM BY DIFFUSION SPECTRUM CODE DIVISION, BASE STATION FOR A DIFFUSION SPECTRUM MULTIPLE ACCESS SYSTEM, DIFFUSION SPECTRUM CODE ". A selected user device transmits a subscription at a selected time interval from the time intervals of the common packet channel. The base station, in response to receiving the transmitted subscription, selects an unused code at the moment, if one is available, from a plurality of codes associated with the access opportunity defined by the selected subscription and the selected time interval. The base station transmits an acknowledgment signal comprising an identifier for the selected code. The selected user equipment receives the acknowledgment signal. The selected user equipment and the base station communicate using the selected code.
