To provide an object lesson below said method is elaborated, be example with real time business and non-real-time service.
In downlink multiuser MIMO-ofdm system, suppose that number of users is K in the sub-district, total sub-carrier number is N, in order to reduce the field feedback amount, adjacent R number of sub-carrier is merged into a subband, as the Frequency Distribution unit of a minimum.The minimum time unit of scheduling is a sub-frame (1ms), and each subframe is made up of Symbol_num OFDM symbol.The number of transmit antennas of base station side is Nt (being set to 4), and each user has Nr (being set to 2 here) reception antenna.Adopt in the system Adaptive Modulation and Coding (Adaptive Modulation and Coding, AMC) so that the transfer of data of variable Rate to be provided, Modulation and Coding Scheme (Modulation Coding Scheme, MCS) shown in table one:
Table one:
| ?Index | Modulation | Coding?Rate | SNRreq(dB) | |
| ?MCS1 | BPSK | 1/4 | -3.4 | |
| ?MCS2 | BPSK | 1/2 | -0.4 | |
| ?MCS3 | QPSK | 1/2 | 2.2 | |
| ? | QPSK | 3/4 | 5.2 | |
| ? | 8PSK | 2/3 | 7.6 | |
| ? | 16QAM | 3/4 | 10.9 | |
| ? | 64QAM | 2/3 | 14.5 |
Below specifically introduce scheduling scheme:
Suppose to have four types of different service streams: the networking telephone (Voice over Internet Protocol, VoIP), video flowing (Video Streaming), World Wide Web (World Wide Web, WWW) with do one's best (Best Effort, BE).Four kinds of Business Streams have different qos requirements.
(1) Business Stream with different user divides into groups, and four kinds of Business Streams are divided into into four groups, and priority orders is set is:
VoIP＞Video?Streaming＞WWW＞BE
(2), can obtain the bit number bit_persymbol that each OFDM symbol can transmit according to the MCS in the table one
m, m={1 ..., mcs_num}, wherein mcs_num is the number (mcs_num=7 in the emulation) of MCS.Bit number that resource can be carried in the time of can obtaining adopting a certain Modulation and Coding Scheme by following formula, i.e. each subband of each subframe bit number that can carry:
bits_perblock
m＝bits_persymbol
m*symbols_num*R*min(M
T，M
R)，
m＝{1，...，mcs_num}
I.e. the bit_perblock that lists in the table one for calculating by following formula
m, m={1 ..., mcs_num}.
It is following to calculate the bit number that each resource on average carries then:
Estimate on average that according to channel situation just can be every type of Business Stream set of dispense corresponding bandwidth resource like this.
(3) at first calculate total amount of bits in the user cache formation of every type of Business Stream group.For i the user of Business Stream class k, the amount of bits in its buffer queue is bits_in_queue
K, i, then have:
Wherein, flow_num
kThe number of the Business Stream that comprises among the expression Business Stream class k.Like this, the sub band number band_num that needs of professional k
kCan be by computes:
Wherein, band_amount
kIt is the needed sub band number of professional k in the current subframe; 0＜r
k＜1, r
kBe used to control the amount of every type of Business Stream component, prevent the waste of resource, improve the utilance of resource to resource.Because priority first height of VoIP; When resource division, should at first give its Resources allocation; Be Video Streaming then, give WWW, BE Resources allocation successively, get access to till deserved resource or resource be assigned with up to VoIP, Video Streaming, WWW, BE.
(4), after resource distributes, whenever need readjust, distribute first resource between all kinds of Business Stream groups at a distance from certain cycle because professional sudden.If in this cycle, the situation that still exists the real time business group to be not being met, the thresholding that inadequate resource will take place triggers, and need from the non-real-time service group, transfer resource to the real time business group, up to the requirement of satisfying the real time business group.If in this cycle, the resource of real time business group has residue, and the thresholding that resources left will take place triggers, and need the surplus resources of real time business group be transferred to the non-real-time service group.Trigger for the thresholding of real time business group resources left, as triggering thresholding, the resources left degree refers to the ratio of the sub band number of every kind of current sub band number of having occupied of business and the current actual needs of this business with the maximum resource redundancy of all kinds of service groups.When the resources left degree of Business Stream class k surpasses the resources left degree thresholding of maximum permission, will produce triggering, residual resource is transferred out to the non-real-time service group in the base station from the resource that the real time business group is occupied.
(5) after every type of Business Stream group obtains corresponding resource, just can carry out the single professional scheduling of multi-user in Business Stream group inside.Professional inner scheduling will be selected suitable scheduler, guarantees to improve the spectrum efficiency of system under the prerequisite of user fairness and QoS demand, reaches the local optimum of resource allocation.
The non-real-time service group all adopts classical PF (Proportional Fairness) algorithm, and the real time business group all adopts M-LWDF (Modified Largest Weighted Delay First) algorithm.Following mask body provides the description of two kinds of algorithms:
A. non-real-time service
PF (Proportional Fairness) algorithm is adopted in the scheduling of non-real-time service group, and arthmetic statement is following: suppose that this business obtains M
kIndividual subband, at time slot t, the priority of user i on subband j is:
Wherein, ch_rate
I, jThe bit number that (t) on subband j, can transmit for user i,
For user i at a time window T
cThe interior Mean Speed that receives bit.
For each subband j, select priority
I, jMaximum user i
*, that is:
This subband j is distributed to its corresponding user i
*
If user i does not have data bit to transmit in current time slots, then its priority is changed to 0; At each time slot t, all users will upgrade its Mean Speed
as follows:
If user i does not transmit bit, then tran_rate in the t-1 time slot
i(t-1)=0;
B. real time business
M-LWDF (Modified Largest Weighted Delay First) algorithm is adopted in the scheduling of real time business group, and existing research shows that this algorithm can reach throughput-optimal.
Suppose that this business has obtained M
kIndividual subband.At time slot t, the priority of user i corresponding subband j is following:
Wherein,
δ
iThe time delay of first bag in the current cache formation of representative of consumer i surpasses max_delay
iProbability; Max_delay
iBe the maximum packet delay that user i allows, delay
iTime delay for first bag in the formation of user i; Ch_rate
I, jThe bit number that (t) on subband j, can transmit for user i,
For user i at a time window T
cThe interior Mean Speed that receives bit.
For each subband j, select priority
I, jMaximum user i
*, that is:
This subband j is distributed to its corresponding user i
*
Business Streams all in a Business Stream group all belong to same classification, have identical qos requirement, so max_delay
iAnd δ
iIdentical to all users.Therefore the priority formula can be reduced to:
Wherein, max_delay representes the maximum packet delay that business allowed in this Business Stream group.
