ABSTRACT:
Techniques for scheduling terminals with different scheduling delays. Initially, the scheduling delay of each terminal is determined, and the total available transmit power and the link efficiency of each terminal are estimated. In a first scheme, the terminals are scheduled for data transmission based on the longest scheduling delay among the delays of all terminals. In a second scheme, each terminal is assigned a particular priority based on its scheduling delay, and the terminals are scheduled based on their assigned priorities. In a third scheme, the terminals are categorized into classes based on their scheduling delays. A percentage of the total available transmit power is allocated to each class, and the terminals in each class are scheduled based on the transmit power allocated to that class. In a fourth scheme, the terminals are scheduled for data transmission, and the schedule for each terminal is applied after its scheduling delay.
