The present packet scheduling algorithm gives cellular network operators
greater flexibility in adjusting the way resources are allocated among
interactive best-effort data users. The present packet scheduling
algorithm is capable of allocating radio resource dynamically, not only
based on channel conditions, but also to achieve different performance
trade-offs among users with different link qualities. According to the
algorithm, channel quality is determined for each user. Channel
efficiency is calculated and the channel efficiency value is used as the
primary factor in weighting the delivery of packets to (or from) a given
user. In a packet schedule weighting equation, a value of exponent may be
varied from negative to positive to give good (or bad) users better
service. However, performance of users with bad channel qualities
degrades the performance of good channel users in a disproportionate
manner.
