Abstract:
1. In a wireless communication system adapted for packet data transmissions, the system having at least one mobile station with pending data at a transmitter, a method comprising: calculating a packet delay time for a first receiver of the at least one mobile station with pending data; comparing the packet delay time to a first threshold; if the packet delay time violates the first threshold, calculating a first delay term; calculating a priority function for the first receiver using the first delay term; and scheduling transmissions to the receiver according to the priority function, wherein a packet delay time function is calculated as: g(d)=DRCMAX/DRCAVE for packet delay time requirement greater than the first threshold, wherein DRCMAX is a maximum of DRC values for receivers in an active set of the transmitter, and wherein DRCAVE is an average DRC value for the first receiver, wherein DRC is a data rate associated with at least one mobile station and wherein g(d) is a packet delay time function.
