Specific implementation mode
In order to make the above objects, features, and advantages of the present application more apparent, below in conjunction with the accompanying drawings and it is specific real
Applying mode, the present application will be further described in detail.
Before introducing the embodiment of the present application, the two kinds of frame formats scheduled in LTE are introduced first：FDD(Frequency
Division Duplexing frequency division duplex) and TDD (Time Division Duplexing time division duplexs).It is referring to Fig.1
The frame format structure chart of FDD is the frame format structure chart of TDD with reference to Fig. 2.The length of two kinds of frame formats is all 10ms, including 10
A subframe, each subframe are 1ms.The characteristics of FDD is to be respectively transmitted sub-frame of uplink and downlink using two independent channels
Frame.Sub-frame of uplink is the message that UE is sent to base station, and downlink subframe is the message that base station is sent to UE.Appoint any one in one frame
Subframe can be configured to ABS subframes, and only subframe 3,4,7,8,9 can just be configured to MBSFN sub-frame.The difference of TDD and FDD
It is divided into sub-frame of uplink, downlink subframe and special subframe for, the subframe in the same frame, wherein special subframe is divided into as three parts,
Downlink data can be transmitted in respectively DwPTS, GP and UpPTS, DwPTS, and upstream data can be transmitted in UpPTS, and GP converts for uplink and downlink
Point does not send any data.In special subframe, the duration of DwPTS, GP and UpPTS, DwPTS are configured depending on ascending-descending subframes.
In addition to special subframe, other subframes are sub-frame of uplink or downlink subframe, then depend on ascending-descending subframes and configure.Each subframe packet
OFDM (orthogonal frequency division multiplexing, the Orthogonal Frequency Division Multiplexing) symbolic number contained is fixed
, the configuration of the cyclic prefix dependent on OFDM symbol is different and different, and for downlink subframe, preceding (1-3) a OFDM symbol passes
Defeated is control information, and specific number depends on the network configuration of each operator, only subsequent OFDM symbol just really to hold
Carry user data.
The ratio of resource allocation between macrocell and Microcell, i.e. ABS or MBSFN sub-frame affects fairness, money
The items network index such as source utilization ratio, network throughput, plays a crucial role to e-ICIC performances.LTE defines for e-ICIC
ABS/MBSFN subframe patterns interact ABS/ by the X2 interface of 3GPP interaction definition between eNB (base station) between adjacent eNB
The configuration of MBSFN, is defined as bitmap (bitmap) form, and each subframe corresponds to a bit in bitmap, some bit
It is 1, then corresponding subframe is ABS/MBSFN.For FDD frame formats, the length of bitmap is 40ms, i.e., pattern is week with 40ms
Phase repeated application.Determine that the ratio of ABS or MBSFN sub-frame determines in the one style period, shared by the number of ABS/MBSFN
Ratio, it is determined that ratio can further determine that each ABS/MBSFN according to the regulation of agreement or the demand of other algorithms
Position, that is, determine that the ratio of ABS or MBSFN sub-frame is e-ICIC most important, most basic step.
Be linked into macrocell and be not affected by strongly disturbing UE and be known as MaUE (Macro-cell UE), be linked into macrocell and
It is known as VMaUE (Victim Macro-cell UE) by strongly disturbing UE, the UE for being linked into Microcell is known as MiUE (Micro-
cell UE).When determining the ratio of MBSFN sub-frame or ABS, need consider MiUE, MaUE and VMaUE business demand with
And type of service.
Currently used ABS or MBSFN sub-frame proportional allocation have：Iteration adjustment method uses exploratory method, first
One ratio is set, and the utilization rate of statistics ABS/MBSFN subframes increases ratio if utilization rate is higher within a certain period of time
Example, if utilization rate is relatively low, reduces ratio.But measurement period of the tentative approach due to needing certain time, belong to
Semi-static algorithm, real-time are poor.If ratio setting is unreasonable, for example, UE business demands variation it is very fast when, resource will be caused
It is mismatched with UE business demands, influences UE perception or resource utilization.
One of the core concepts of the embodiments of the present application is that passing through GBR traffic and NGBR business speed to different priorities
Rate demand is counted, and is preferably that the high GBR traffic of priority carries out resource reservation, to remaining resource using Nash Equilibrium
As a result it is divided.
With reference to Fig. 3, the resource allocation sides enhancement type district interference coordination e-ICIC of LTE-A of the application a kind of are shown
The step flow chart of method embodiment, can specifically include following steps：
Step 301, it counts the guarantee bit rate GBR traffic rate requirement of macrocell user and does not ensure bit rate
NGBR service rate demands；The macrocell user includes：It is disturbed macrocell user VMaUE and undisturbed macrocell user

Step 302, the required GBR of GBR traffic for the macrocell user being calculated using the GBR traffic rate requirement
Resource；
Step 303, Nash Equilibrium result is generated using the rate requirement of the NGBR business；
Step 304, the NGBR business demand resources of VMaUE are calculated using Nash Equilibrium result；
Step 305, it is obtained later using the distribution as a result, determining e-ICIC resources.
Running time-frequency resource defined in resource, that is, LTE protocol for e-ICIC is carried out by time domain, and resource is exactly son
Frame, e-ICIC resources refer to just ABS or MBSFN sub-frame, for example, for FDD, since FDD uses the pattern period of 40ms, i.e.,
40 subframes are 1 pattern period, the ratio of ABS or MBSFN sub-frame, i.e., in the interior ABS in 1 pattern period or MBSFN sub-frame institute
The number accounted for.In the embodiment of the present application, before determining the ratio of ABS or MBSFN sub-frame, first count MaUE and
The business demand and type of service of VMaUE, since different business has QoS (Quality of Service, service quality)
Different requirements, by QCI (QoS Class Identifer), it is different with rate requirement that LTE defines 9 kinds of QoS grades altogether
Business, wherein QCI values are smaller, and priority is higher.QCI 1-4 are GBR (Guranteed Bit Rate) business, 5-9 NGBR
Therefore (Non Guranteed Bit Rate) business when carrying out resource allocation, needs to consider service priority.To GBR industry
Business and NGBR business separately count, and the resource of GBR traffic are reserved, surplus resources are further according to Nash Equilibrium, in NGBR industry
It is divided between business.
In a kind of preferable example of the application, the step 302 may include：
Sub-step S21 obtains the average subframe bearer rate of macrocell；
The GBR traffic rate requirement divided by the average subframe bearer rate are obtained the macrocell by sub-step S22
The required GBR resources of GBR traffic of user.
In order to reduce complexity, reduction delay when carrying out resource allocation, does not consider the channel quality of UE, but according to flat
Mean value is handled, different scene and network structure, and Mean Speed is different, it is assumed that is B.For LTE system, can be converted into
The rate that each subframe can carry, for FDD frame formats, the rate that can be carried of each subframe is B/10；For tdd frame lattice
Formula needs to be determined according to ascending-descending subframes configuration and special subframe configuration.Equally, certain business demand is given, can also be rolled over
It calculates the demand and needs the number of sub frames occupied, i.e., determined in a radio frames according to ascending-descending subframes configuration and special subframe configuration
The number of OFDM symbol in all downlink subframes, can be obtained each OFDM symbol averagely with B divided by OFDM symbol number can carry
Data rate, according to the OFDM symbol number for being used for transmission data in each conventional downlink subframe and DwPTS, you can obtain
The data rate that each downlink subframe can be carried averagely.
In a kind of preferable example of the application, the step 302 can also include：
The GBR traffic rate of MaUE divided by the average subframe bearer rate are obtained into the GBR resources of MaUE；
The GBR traffic rate of VMaUE divided by the average subframe bearer rate are obtained into the GBR resources of VMaUE.

Seek resource.
As an example it is assumed that shared M kind GBR traffics, ensure that rate is respectively Vi, i=0,1 ..., M-1.Assuming that in cell
Co-exist in N number of UE, wherein P MaUE and Q VMaUE, P+Q=N.For some UE, the number there are i-th kind of GBR traffic is
Ki, i=0,1 ..., M-1, then entire cell, MaUE and the total GBR traffic rates of VMaUE are respectively：
Corresponding number of resources is denoted as (as unit of subframe)
AsDivided by the value of average bearer rate subframe, can be decimal；
AsDivided by the value of average bearer rate subframe, can be decimal；
AsDivided by the value of average bearer rate subframe, can be decimal.
In a kind of preferable example of the present embodiment, the step 303 may include：

In the embodiment of the present application, the utility function of macrocell is：
Wherein, UMaUEAnd UVMaUEThe utility function of respectively MaUE and VMaUE can be defined as MaUE and VMaUE demands
NGBR business rate summation, the NGBR service rate demands of the MaUE obtained by statistics and VMaUE obtain；dMaUEAnd dVMaUE
Respectively being not coordinated with for MaUE and VMaUE utility functions a little may be defined as the minimum speed limit of MaUE and VMaUE NGBR business and want
It asks, for TCP (Transmission Control Protocol transmission control protocols), FTP (File Transfer
Protocol (File Transfer Protocol)) etc. the business demand done one's best, minimum speed limit can be set as 0.
Thus,
Above-mentioned formula is solved,
Wherein, α is ABS or MBSFN sub-frame resource ratio shared in all downlink subframes of a radio frames.
