In a packet data transmission and reception system a media access control (MAC) message is broadcast by a base station to a plurality of mobile stations. The MAC message contains packet data transmission scheduling information which allows the base station to preemptively control mobile station access to traffic channels in order to maximize the efficiency of packet data transmissions and allow scheduling consideration including priority access, quality of service and maximum bytes per transfer. The MAC message consists of a control frame structure which comprises scheduling parameters including MAC IDs fields, activity fields, and a field representing the number of free traffic channels in a cell. These parameters enable multiple mobile stations to share, in a time multiplexed fashion, traffic channels for packet data transmission on CDMA based mobile communication systems.

[ What is claimed is:] [1.] A method for transmitting packet data from a plurality of mobile stations to a base station, comprising the steps of:broadcasting media access control (MAC) information from the base station to the plurality of mobile stations for simultaneous reception by the plurality of mobile stations, wherein the MAC information comprises a MAC control frame structure for conveying packet data transmission scheduling information, the MAC control frame structure including a plurality of activity fields, one activity field for each active packet data mobile station within a cell, a Next MAC ID field which specifies the identification of a mobile station to be given traffic channel access in a next time slot, and a #Free Channel field which specifies a number of available traffic channels for packet data service at the base station;receiving the broadcast MAC information at the plurality of mobile stations; andfor a mobile station specified in the MAC information, transmitting packet data to the base station at a time specified by the MAC information.
