Description
Technical field
The present invention relates to the communications field, in particular to a kind of dispatching method and base station that is used for multicarrier system.
Background technology
Scheduling expression be a notion relevant with chronological order, dispatching algorithm wishes to solve is when a plurality of user's contention for resources, how to determine a kind of SO service order.On theoretical system, dispatching algorithm should be a branch of queueing theory.In order on limited frequency domain resource, to realize better system performance, at RRM (Radio Resource Management, abbreviate RRM as) various functions in, packet scheduling is most critical one ring that influences systematic function, and good system resource allocation scheme is the efficient of decision systems to a great extent.
Traditional grouping scheduling method has Round Robin (RR), maximum signal to noise ratio scheduling (Max C/I), direct ratio equity dispatching (PF).Suppose to use m
iThe priority valve of representing user i is promptly according to m
iSort to the user and to carry out resource allocation.Round Robin then makes m
i=k, k ∈ U[a, b], promptly make the scheduled probability of each user equate, consider the fairness of system fully, but do not reflected channel conditions, reduced the efficient of system.The maximum signal to noise ratio scheduling then makes m
i=fun (SINR
i), wherein fun () is a monotone nondecreasing function.This method can obtain the highest band efficiency, but has ignored fairness, can cause the service of certain customers to be not being met.In the direct ratio equity dispatching, make m
i=fun (CQI
i)/Packet_Window
i, CQI wherein
iBe user's channel feedback indication, Packet_Window
iBe the information of transmitting in user's certain hour window.This algorithm synthesis the pluses and minuses of repeating query and maximum signal to noise ratio, taken into account band efficiency and fairness.

Because the increase of type of service, for grouping scheduling method has brought new reference frame, comprising: (1) bandwidth, packet scheduling algorithm should be able to provide its QoS required minimum transmission rate for various applied business.(2) time delay, packet scheduling algorithm should be different Business Streams time delay assurance end to end are provided, and time delay shake requirement.(3) justice, packet scheduling algorithm must reasonably be distributed to different Business Streams to usable bandwidth resources, and avoids phase mutual interference each other, and service quality can both be protected.(4) complexity and extensibility, dispatching algorithm realizes should be fairly simple.In express network, the time of a grouping of transmission is very little, so dispatching algorithm must be finished in the short time packet scheduling, this just requires dispatching algorithm simple as far as possible, is easy to realize.Increase and link rate excursion greatly the time when Business Stream quantity in addition, dispatching algorithm must effectively be worked, and this requires dispatching algorithm to be with good expansibility.
It is to realize improving the of paramount importance technology of Wideband Code Division Multiple Access (WCDMA) (WCDMA) network high-speed downlink message transmission rate that high-speed downlink packet inserts (HSDPA) technology, it is the Enhanced Technology that 3GPP introduces in order to satisfy the asymmetric demand of up-downgoing data service in Release 5, it can be on the basis that does not change the WCDMA system network architecture of having built, improve user's downstream data traffic speed (theoretical maximum can reach 14.4Mbps) greatly, this technology is to improve a kind of important technology of downlink capacity and data service rate in the WCDMA networking.
Along with the downward evolution of HSDPA, the HSPA+ technology has been put on work schedule by 3GPP.In order to obtain higher downstream rate and the more type of service of support, multicarrier is introduced in the HSDPA system as the research focus of HSPA+, becomes the multi carrier wave high-speed downlink link packet and inserts (MC-HSDPA).The design relation of scheduler is especially supported multiple mixed service to the performance of whole system in the MC-HSDPA system, scheduler research is extremely necessary.
In the correlation technique, scheduler is with the channel CQI of the feedback foundation of priority valve as scheduling, but since the situation such as untimely of CQI feedback can make the more current channel situation of CQI that bigger deviation is arranged, thereby cause the scheduling process inaccuracy.
