Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only should be appreciated that specific embodiment described herein
Only in order to explain the present invention, it is not intended to limit the present invention.
The specific embodiment of the invention provides a kind of bandwidth adjusting method between macro cell and micro cell, and the method is by grand
Base station performs, and the method is as in figure 2 it is shown, include:
S21, receive the real time status information of Microcell that micro-base station sends；
Above-mentioned real time status information can include but not limited to: Microcell real time load, frequency range utilization rate, use
Family adjusts encoding scheme (modulation and coding scheme, MCS) information or user throughput etc..
S22, judge according to this real time status information the frequency range of macrocell and Microcell the need of adjustment, accordingly
Decide whether adjust macrocell and the frequency range of Microcell according to this real time status information.
The method that the embodiment of the present invention provides can decide whether to adjust macrocell and micro-according to real time status information
The frequency range of community, whole adjustment process is dynamically to adjust, it is not necessary to any artificial operation, so it has tune
Perfect square just, the advantage not wasting frequency range.
It should be noted that above-mentioned deciding whether accordingly adjusts macrocell and micro-according to this real time status information
The concrete grammar of the frequency range of community can be, when judged result be frequency range need adjust time, determine need according to should
Real time status information adjusts macrocell and the frequency range of Microcell, and performs to adjust grand according to this real time status information
Community and the frequency range of Microcell, when judged result be frequency range need not adjust time, otherwise end operation.
Optionally, it is achieved judge that the frequency range of macrocell and Microcell is the need of tune according to this real time status information
Whole method is as it is shown on figure 3, specifically may include that
S31, calculate according to this real time status information the macrocell before adjustment and Microcell status information it
With；
S32, determine frequency range value to be adjusted, according to frequency range value to be adjusted and the macrocell before adjusting and small
The frequency range value in district calculates the status information sum of macrocell to be adjusted and Microcell；
S33, judge that the status information sum of the macrocell before adjusting and Microcell is whether grand little less than to be adjusted
The status information sum of district and Microcell, in this way, then judges that the frequency range of macrocell and Microcell needs to adjust,
As no, then judge that the frequency range between macrocell and Microcell need not adjust.
Illustrating to realize the method for S22 with an actual example below, status information here gulps down with user
As a example by the amount of telling (in a practical situation, it would however also be possible to employ other status information, such as real time load), need
Be noted that the quantity of Microcell here as a example by 1 Microcell, in a practical situation, if had
Multiple Microcells, then need to increase the handling capacity of all Microcells, it is assumed that the user throughput of macrocell is:
XM1；The user throughput of Microcell is: XS1；The user throughput of the macrocell after to be adjusted is: XM2；
The user throughput of Microcell is: XS2；If XM1+XS1＜ XM2+XS2；Then judge to need to adjust frequency
Width, if XM1+XS1≥XM2+XS2；Then judge to need not adjust frequency range.
It should be noted that the computational methods of above-mentioned S31 and S32 can use the computational methods of prior art,
The method specifically may refer to 3GPP 36.213 and 3GPP 36.321.
Realize the method according to this real time status information adjustment macrocell and the frequency range of Microcell as shown in Figure 4,
Specifically may include that
S41, calculate the frequency range value of adjustment according to this status information；
S42, according to adjust frequency range value, macrocell and Microcell adjustment before frequency calculate macrocell and
Frequency after the adjustment of Microcell；
S43, set up the virtual subdistrict of the frequency after macrocell adjusts and set up the void of frequency after Microcell adjusts
Intend community；
S44, the user of macrocell is switched to the virtual subdistrict that macrocell is corresponding, the user of Microcell is switched
The virtual subdistrict corresponding to Microcell；
S45, after switching completes, delete community corresponding to frequency before macrocell adjusts, delete Microcell and adjust
The community that whole front frequency is corresponding.
The method realizing S42 is specifically as follows: illustrate as a example by macrocell below, the adjustment side of Microcell
Formula is the same with macrocell, is not repeating, it is assumed that user only has 30M (2490khz ~ 2520khz) even
In the case of continuous frequency spectrum, macrocell frequency (before adjustment) F1=2500khz, Microcell frequency (before adjustment)
F2=2515khz, BW1=20M(macrocell frequency range, before adjustment), BW2=10M(Microcell frequency range,
Before adjustment), now, it is assumed that macrocell needs to adjust to 10M from 20M, and Microcell needs to adjust from 10M
To 20M, then the frequency range value adjusted is 10M, and macrocell calculates F1 (after adjustment)=F1 and adjusts frequency range
/2；I.e. F1=2495khz；Microcell calculates F2 (after adjustment)=F2 and adjusts frequency range/2；I.e. F2
=2510khz；It should be noted that above-mentioned formula may be otherwise varied along with the difference of F1, F2 value, because of
For in LTE, in order to avoid the repetition of frequency, the value of F1, F2 can be chosen according to the scope of frequency,
Such as, as above-mentioned F1=2510khz；During F2=2495khz, F1 (after adjustment)=F1+ adjusts frequency range/2；
I.e. F1=2515khz；F2 (after adjustment)=F2+ adjusts frequency range/2, i.e. F2=2500khz.
It should be noted that the community realizing needing during the method for S44 avoiding macrocell corresponding with macrocell it
Between signal disturbing, in order to avoid interference, the method avoided interference can be used, the time-division scheduling mode
When being scheduling, macrocell scheduling odd number radio frames, the virtual subdistrict scheduling even number radio frames that macrocell is corresponding；
Can certainly be: macrocell scheduling even number radio frames that the virtual subdistrict scheduling odd number that macrocell is corresponding is wireless
Frame, and the scheduling mode of the virtual subdistrict corresponding with Microcell, Microcell and the above-mentioned scheduling mode avoided interference
Identical, do not repeating.When frequency division scheduling mode is scheduling, compare the frequency before adjustment and
The scope of the frequency after adjustment, as the frequency point ranges before adjustment includes the frequency point ranges after adjustment, then adjusts
Frequency point ranges after adjusting is not dispatched by the community that front frequency is corresponding, as the frequency point ranges after adjusting comprises tune
Frequency point ranges before whole, then the frequency point ranges before adjusting do not dispatched by community corresponding to frequency after adjusting, this
Sample avoids the community before adjusting and the interference between the community after adjustment, for an actual example
Bright, it is assumed that the frequency of macrocell is: to assume that user only has 30M (2490khz ~ 2520khz) continuous frequency spectrum
In the case of, macrocell frequency (before adjustment) F1=2500khz, macrocell frequency range 20M, now need grand
The frequency range of community is adjusted to 10M, then F1 (after adjustment)=2495khz, and now macrocell is just to (2490khz
~ 2495khz) do not dispatch, the frequency of this scope is left virtual subdistrict corresponding to macrocell for practical, only scheduling
(2495khz ~ 2500khz), thus avoids the interference of two minizones, and the realization of this mode is only certainly
Applied before S45, if the community before Tiao Zhenging is deleted, then without considering between former community and virtual subdistrict
Interference, certainly avoid the need for limiting adjust after the scheduling of community.
The method realizing S41 is specifically as follows: calculate all frequency ranges to be adjusted according to this status information grand little
The status information sum of district and Microcell, determines all frequency range macrocells to be adjusted and the status information of Microcell
Frequency range to be adjusted corresponding to maximum in sum is for adjusting frequency range.Because LTE protocol specifies, the frequency of LTE
Wide being only possible to is 1.4,3,5,10,20 (units M)；So no matter this community (includes macrocell and small
District) frequency range be how many, the value of its all frequency ranges to be adjusted has 4, calculates 4 the most respectively and waits to adjust
Macrocell corresponding to whole frequency range value and the status information sum of Microcell, find out the maximum in 4 and value
The adjustment frequency range that corresponding frequency range to be adjusted is in S41.Below as a example by an actual example, false
If the frequency range of macrocell is 20M, frequency range value the most to be adjusted has: 10M, 15M, 17M and 18.6M；
The most each frequency range value all can calculate the status information sum of a macrocell and Microcell, find out 4 and
The frequency range value to be adjusted that in value, maximum is corresponding is the frequency range of adjustment, and the advantage so selected is can be by
The effect that frequency range adjusts maximizes, because the gain of status information that the frequency range now adjusted is brought is the most notable,
Effect for macrocell and Microcell is best.
When the frequency range of macrocell and Microcell is in discontinuous frequency range, it is achieved adjust according to this real time status information
The method of the frequency range of whole macrocell and Microcell is as it is shown in figure 5, include:
S51, calculate the frequency range value of adjustment according to this status information；
S52, the community determining increase frequency range and the community of minimizing frequency range；
S53, according to the frequency range value adjusted with reduce the frequency before the community of frequency range adjusts and calculate and reduce frequency range
The frequency of community；
S54, according to the frequency range value after adjusting with reduce the frequency point ranges of community of frequency range and calculate and increase frequency range
The frequency of community, and the frequency of community of the subdistrict frequency point and minimizing frequency range increasing frequency range do not intersects；
S55, the virtual subdistrict setting up the frequency of the community reducing frequency range and foundation increase the frequency of the community of frequency range
Virtual subdistrict；
S56, the user of community reducing frequency range is switched to reduce the virtual subdistrict that the community of frequency range is corresponding, will
Increase the certain customers of community of frequency range and be switched to increase the virtual subdistrict that the community of frequency range is corresponding；
It should be noted that the determination method of the certain customers in above-mentioned S56 can use various ways, example
As switched the user of a fixed proportion to virtual subdistrict, naturally it is also possible to adjust according to the frequency range value of virtual subdistrict
Whole switching proportion, the embodiment of the present invention does not limit to the determination method of above-mentioned certain customers.
S57, after switching completes, reduce community corresponding to frequency before the community of frequency range adjusts.(need spy
Not mentionleting alone bright, the community increasing the frequency before the community adjustment of frequency range here corresponding needs to retain).
The implementation method of S53 and S54 is described with an actual example below, it is assumed here that Microcell is
Reducing the community of frequency range, its frequency point ranges is (2490khz ~ 2505khz), BW1=10M(macrocell frequency range,
Before adjustment), BW2=20M(Microcell frequency range, before adjustment), Microcell frequency (before adjustment) F2=2500khz,
Now, it is assumed that macrocell needs to adjust to 20M from 10M, and Microcell needs to adjust to 10M from 20M, then
The frequency range value adjusted is 10M, and Microcell calculates F2 (after adjustment)=F2 and adjusts frequency range/2；I.e. F2
=2495khz；Macrocell calculates the maximum in F1 (after adjustment)=2505(Microcell frequency point ranges,
The most in actual applications, it is also possible to for minimum of a value, when for minimum of a value, the minus sign in formula to be adjusted to add
Number) adjust frequency range/2；I.e. F1=2500khz.It should be noted that due to now F1=2500khz
If beyond the frequency point ranges of macrocell emitter, then need to newly increase an emitter to complete F1
The transmitting of=2500khz.
It should be noted that need when realizing the method for S56 to consider to reduce community and the minimizing frequency range of frequency range
Virtual subdistrict corresponding to community between signal disturbing, in order to avoid interference, can use and avoid interference
Method, when the mode of time-division scheduling is scheduling, reduces the cell scheduling odd number radio frames of frequency range, reduces
Even number radio frames is dispatched in the virtual subdistrict that the community of frequency range is corresponding；Can certainly be: reduce the community of frequency range
Scheduling even number radio frames, reduces the virtual subdistrict scheduling odd number radio frames that the community of frequency range is corresponding, and increases frequency
Wide community is not repeated due to frequency, so it need not consider signal disturbing.When frequency division scheduling mode is adjusted
When spending, the frequency point ranges reducing virtual subdistrict corresponding to frequency range community is not dispatched by the community reducing frequency range, this
Sample, just it can be avoided that area interference, illustrates with an actual example, reduces the frequency point ranges of frequency range community
(2490khz ~ 2520khz) assumes that the frequency reducing frequency range community is (before adjustment) F1=2500khz, reduces
Frequency range community frequency range 20M, now needs the frequency range reducing frequency range community is adjusted to 10M, then F1 (adjusts
After whole)=2495khz, now reduces frequency range community and does not just dispatch (2490khz ~ 2495khz), by this model
The frequency enclosed is left for and is reduced the virtual subdistrict practicality that frequency range community is corresponding, only scheduling (2495khz ~ 2500khz),
Thus avoiding the interference of two minizones, the realization of this mode was only applied before S57 certainly, if
Community before adjustment is deleted, then without considering the interference between former community and virtual subdistrict, certainly avoid the need for
Limit the scheduling of community after adjusting.It addition, for embodiment as shown in Figure 5, correspondence increases the little of frequency range
There is not the interference of minizone in district, so need not make any adjustments in scheduling.
