Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of MAC traffic scheduling method, device and base station.
Background technology
At present, when user terminal occurs community switching, MAC (Media Access Control, get involved by media
Key-course) mode of flow scheduling has following several:
1, maximum C/I algorithm
Due to UE in space be random, then residing wireless environment is the most different, from AMC's above
Mechanism is it is known that the UE of wireless environment good (C/I is good) can report bigger CQI (Channel Quality
Indicator, quality of wireless channel), thus obtain higher speed.So if it is desired to obtaining maximum fan
If district's handling capacity, best bet is exactly all to the user that C/I is best by RB (Resource Block).
The benefit of this algorithm maximum is exactly sector throughput and the resource utilization that can obtain maximum, but also has individual
Fatal shortcoming, it is simply that unfair, those are in the user covering middle and edge owing to C/I is not as covering
The user at lid center, the chance that may a little be allocated RB does not all have, so just creating second algorithm,
Polling algorithm.
2, polling algorithm RR
Polling algorithm is just as its name, and each user takes turns, it is to avoid maximum C/I algorithm cannot be taken into account weak
That situation of gesture user, each user's mean allocation RB resource under sector.But sacrifice the maximum of sector
Handling capacity and resource utilization.
3, proportional fair algorithm PF
Both above algorithm takes a method for compromise, proportional fair algorithm.The original intention of proportional fair algorithm is
Distributional equity should be taken into account again in view of the C/I residing for user simultaneously.
Three of the above method has an obvious defect, that is, simply considering that radio conditions is distinguished is
No high-quality user according to, and practical situation is whether that the judgement of high-quality user is with radio conditions is entirely without relation.
It addition, said method user terminal can lose original information behind new community, it is therefore desirable to open from zero completely
Beginning is recalculated, and user terminal can be caused some data degradations, cause the hydraulic performance declines such as dispatching efficiency.
