Abstract:
1. A wireless transmit/receive unit (WTRU) for conducting wireless communications with a plurality of other WTRUs that implements a process for controlling transmission of wireless communication data to the other WTRUs comprising: a scheduler configured to queue data packets in one of a plurality of queues for transmission to the other WTRUs based on selected criteria including data class of service such that: said scheduler configured to selectively enable transmission of queued data packets by removing a data packet for transmission processing from the head of a selected queue based on priority indexes of data packets concurrently disposed at the heads of the queues; and said scheduler configured to calculate the priority index of a data packet using a delay index based on a current time and the queue arrival time identified with the data, a data rate index based on a data transmission rate associated with the data packet, and a weight factor α, based on data class of service such that the weight factor is applied to adjust the applicable priority index applied to data packets for a queue based on the data class of service associated with that queue according to
