Than algorithm and proportional fair algorithm, wherein the priority that Round Robin algorithm defaults all terminals in a cell is equal,
The probability that i.e. each user is scheduled is identical, and Round Robin algorithm can guarantee the fairness of scheduling, but Round Robin algorithm is simultaneously
The channel situation for not considering different terminals, also means that, the terminal of bad channel quality and the terminal that channel quality is good are scheduled
Probability it is all the same, therefore, scheduler is scheduled the throughput that will affect cell using Round Robin algorithm.Scheduler uses
When max carrier to interference algorithm is scheduled, from high to low according to carrier/interface ratio (the maximum instantaneous transmission rate that terminal can achieve)
Sequence is ranked up terminal to be scheduled, and the scheduler selection highest terminal of carrier/interface ratio is scheduled, and ensure that the benefit of resource
It with rate highest, also ensures that the throughput of cell is maximum, but due to being scheduled using max carrier to interference algorithm, leads to maximum load
Do the chance that relatively low user cannot dispatch, it is seen then that max carrier to interference algorithm does not have fairness.And proportional fair algorithm
Formula are as follows:Molecule is the transmission rate of a certain scheduled terminal current request, and denominator is the terminal
Average transmission rate, fractional value be the terminal priority, if a certain terminal is continuously dispatched, average transmission rate increase
Greatly, priority is caused to reduce, when dispatching next time, scheduler can wait for the terminal that selection priority is high in dispatch terminal from remaining
It is scheduled, if a certain terminal is not scheduled for a long time, average transmission rate is reduced, and is caused priority to increase, is then increased
A possibility that terminal is scheduled, it is seen then that proportional fair algorithm has taken into account fairness and throughput.
But proportional fair algorithm is to determine terminal with the transmission rate of terminal current request and average transmission rate
A kind of method of scheduling of resource of dispatching priority, if the dispatching priority of terminal a is lower than the dispatching priority of terminal b, that
It can be preferably terminal b distribution resource, but terminal a needs when using proportional fair algorithm for the two terminal distribution resources
The resource of acquisition may need the resource that obtains far more than terminal b, alternatively, terminal a compared to terminal b for, time delay is wanted
Ask higher, terminal a needs shorter time delay just to can guarantee that the user of using terminal a has good usage experience, in this feelings
