Method for scheduling packet data transmission
First Claim
1. A mobile station, for operation with a packet data scheduling function of a wireless telecommunications system having a plurality of base stations, the mobile station for receiving a MAC ID assignment from each of said plurality of base stations and storing a plurality of MAC IDs in a memory, monitoring a selected control channel of a plurality of control channels transmit from the plurality of base stations, wherein said selected control channel is associated with a selected base station of plurality of base station and carries to the mobile station packet data activity information associated with a selected MAC ID of said plurality of MAC Ids, said selected MAC ID associated with said selected base station, decoding said selected MAC ID, and in response to decoding said selected MAC ID in the mobile station, determining from said activity information that a packet data channel is allocated to said mobile station by said selected base station.

Abstract
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.

5. A method of operating a mobile station for packet data services in a wireless telecommunications system having a plurality of base stations, said method comprising:
-
receiving, at the mobile station, a MAC_ID assignment from each of the plurality of base stations;
storing a plurality of MAC_IDs in a memory of the mobile station;
monitoring a selected control channel of a plurality of control channels transmit from the plurality of base stations, wherein said selected control channel is associated with a selected base station of the plurality of base stations and carries to the mobile station packet data activity information associated with a selected MAC_ID of said plurality of MAC_IDs, said selected MAC_ID associated with said selected base station;
decoding, in the mobile station, said selected MAC_ID; and
in response to decoding said selected MAC_ID, determining from said activity information that a packet data channel is allocated to the mobile station by said selected base station. - View Dependent Claims (7, 8)
