  • Method and apparatus for scheduling transmissions in wireless data networks
    Publication number: 20050025090
    Abstract: A method and apparatus for scheduling data transmissions is disclosed that reduces the delay variability in transmissions of data. A scheduling metric is calculated as a function of a TCP throughput rate for each mobile terminal in the system. The relative value of this metric for a user is used to schedule data transmissions from that user. As a result, TCP time-outs are reduced or avoided and the throughput and the predictability of system performance are increased.

  • Method and apparatus for improving scheduler performance in wireless packet data systems
    Publication number: 20040266451
    Abstract: A method and apparatus for scheduling data transmissions is disclosed that compensates for link level errors and uses retransmission information to schedule future transmissions from each user. The disclosed method and apparatus utilizes a more accurate measure of users' data rates (i.e., their effective data throughput rates) that accounts for the Frame Error Rate (FER) as well as retransmissions when scheduling transmissions from multiple users.
