IN A SPREAD SPECTRUM COMMUNICATIONS SYSTEM SUPPORTING BURSTY UPLINK AND DOWNLINK DATA PACKET TRANSMISSION TELECOMMUNICATIONS SERVICES, SIGNIFICANT CONCERNS EXIST AS TO THE GENERATION OF UNACCEPTABLE LEVELS OF INTERFERENCE RESULTING FROM PLURAL AND SIMULTANEOUS DATA PACKET TRANSMISSIONS. TO ADDRESS THIS CONCERN, THE SYSTEM SELECTIVELY ORGANIZES AN ACCESS SCHEDULE FOR MOBILE STATION UPLINK DATA PACKET TRANSMISSIONS AND A DELIVERY SCHEDULE FOR DOWNLINK DATA PACKET TRANSMISSIONS. FORM THE UPLINK, THE SCHEDULE IS TRANSMITTED TO PLURAL MOBILE SATIONS (16) IN A CURRENT FRAME, AND IDENTIFIES WHICH ONE OR ONES OF PLURAL MOBILE STATIONS (16) ARE AUTHORIZED TO MAKE AN UPLINK DATA PACKET TRANSMISSION IN A NEXT FRAME. ONLY THOSE MOBILE STATIONS (16) SCHEDULED WITH AUTHORIZATION TO MAKE AN ACCESS IN THE NEXT FRAME THEN TRANSMIT THEIR DATA PACKETS (OR A PORTIONS THEREOF) TO THE BASE STATION (12) DURING THAT NEXT FRAME. ON THE DOWLINK, A NOTIFICATION OF INTENDED DELIVERY IS COMMUNICATED TO DESTINATION MOBILE STATIONS (16) IN A CURRENT FRAME. THE SYSTEM THEN MAKES DOWNLINK DELIVERY IN ACCORDANCE WITH THE SCHEDULE TO THE DESTINATION MOBILE STATIONS (16) IN A NEXT FRAME.(FIGURE 2)
