Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the uplink interference suppressing method schematic flow sheet that the embodiment of the present invention provides.As shown in Figure 1, the method can comprise:
S101, obtain be disturbed community send uplink interference information or uplink interference suppress instruction.
S102, suppress instruction according to the uplink interference information obtained or uplink interference, obtain interference source community and carry out the transmission information of the edge customer of uplink.
S103, carry out the transmission information of the edge customer of uplink according to the interference source community obtained, turn down the transmitting power of the edge termination in interference source community.
The interference that community may be subject to other one or more interference source community is disturbed in the embodiment of the present invention; Interference also may be caused to other one or more community in interference source community.Such as, for community 1 and community 2, community 1 may be the interference source of community 2, also may be subject to the interference of community 2.That is, in the embodiment of the present invention, interference source community is comparatively speaking with being disturbed community.
The executive agent of said method flow process is uplink interference restraining device, and described uplink interference restraining device can be base station, also can be the device be arranged in base station.
In the embodiment of the present invention, in a base station, for each community under this base station, a uplink interference detection module can be set, be used for detecting according to setting cycle the uplink interference information that this community is subject to, or the uplink interference that can be subject to according to this community detected sends uplink interference and suppresses instruction.
When interference source community and be disturbed community be positioned at same base station, in the step S101 of above-described embodiment, the uplink interference restraining device arranged in base station or base station can obtain this and be disturbed uplink interference information that community is subject to or obtain this and be disturbed uplink interference that community sends and suppress instruction from the uplink interference detection module being disturbed community.
When interference source community and be disturbed community be positioned at different base stations, in the step S101 of above-described embodiment, be disturbed the base station at place, community by the interface between base station, as X2 interface, instruction is suppressed to send to the base station at place, interference source community the uplink interference information or uplink interference that are disturbed community transmission.
In above-mentioned steps S101, being disturbed community can detect the uplink interference that this community is subject to according to setting cycle, and such as, being disturbed community can detect low noise every setting-up time interval.Time interval of sense cycle can as required or systematic function arrange.
Further, when being disturbed cell detection and being greater than setting threshold to the uplink interference degree be subject to, the cycle duration of current uplink interference sense cycle can be set to the first duration; When detecting that being disturbed uplink interference degree that community is subject to is less than or equal to described setting threshold, the cycle duration of current uplink interference sense cycle is set to the second duration.Wherein, the first duration is less than the second duration.Such as, the first duration is set to 10 minutes, the second duration is set to 30 minutes.Like this, can according to be disturbed cell detection to be disturbed degree, different sense cycle is set, when be disturbed cell detection to the degree that is disturbed be greater than the threshold value of setting time, shorter sense cycle can be arranged detect low noise, and send uplink interference information or uplink interference suppression instruction according to the low noise detected to interference source community, thus interference source community can be reduced rapidly to the interference being disturbed community.
In above-mentioned steps S102, the transmission information carrying out the edge customer of uplink got can include but not limited to following in one or more: the Bler (Block Error Rate, Block Error Rate) of the throughput of the type of service of the uplink of the edge customer of uplink, the quantity of ascending edge user, ascending edge user, the SNR of ascending edge user, the CQI of ascending edge user and ascending edge user.Wherein, the A2 measurement report that the quantity of ascending edge user receives by the base station at place, interference source community obtains.
Step S103 in above-mentioned flow process realizes by flow process as shown in Figure 2, and as shown in Figure 2, this flow process can comprise:
S201, turn down the transmitting power of the edge termination in interference source community according to the step-length of setting.
Such as, in the specific implementation, step-length can be set to 2dB.
The upstream performance of the edge customer of uplink is carried out in S202, detection interference source community.
For weighing transformation parameter or the transmission information of upstream performance, include but not limited to following in one or more: the Bler of the throughput of the type of service of the uplink of the edge customer of uplink, the quantity of ascending edge user, ascending edge user, the SNR of ascending edge user, the CQI of ascending edge user and ascending edge user.
S203, judge the upstream performance of carrying out the edge customer of uplink in interference source community whether higher than the threshold value of setting.Somely disturb the upstream performance of carrying out the edge customer of uplink in the cell-of-origin threshold value higher than setting, then go to step S204; Otherwise, process ends.Wherein, if carry out the threshold value of upstream performance higher than setting of the edge customer of uplink, then show that the upstream performance of these users is better, otherwise the upstream performance of these users is poor.
Such as, when weighing upstream performance with SNR, can 5dB be set the threshold to, if the SNR of user is greater than 5dB, then shows that the upstream performance of these users is better, otherwise showing that the upstream performance of these users is poor; When weighing upstream performance with CQI, can 7 be set the threshold to, if the CQI of user is greater than 7, then shows that the upstream performance of these users is better, otherwise showing that the upstream performance of these users is poor.
When weighing upstream performance with Bler, and when setting the threshold to a class value, the Bler higher than the user of described class value is less than 10%, and the Bler lower than the user of described class value is greater than 10%.When the Bler of user is higher than described class value, shows that the upstream performance of these users is better, otherwise show that the upstream performance of these users is poor.
Such as, the threshold value of carrying out the upstream performance of the edge customer of uplink in interference source community can be set as that the SNR of ascending edge user be 5dB, CQI be 7, Bler is 10%.
S204, judge whether the transmitting power of the edge termination in interference source community is greater than the minimum emissive power of setting.The transmitting power of some edge terminations of disturbing in cell-of-origin is greater than the minimum emissive power of setting, then return step S201; Otherwise, process ends.
Below to weigh upstream performance with SNR, and threshold value is set as 5dB, and supposes that in interference source community, the current SNR carrying out ascending edge user is 8dB, and the step-length of setting is 2dB, is described in detail the flow process shown in above-mentioned Fig. 2.
First according to 2dB, the SNR of ascending edge user is adjusted, then the SNR of ascending edge user becomes 6dB, because 6dB is greater than the threshold value 5dB of setting, then judge that the transmitting power of the terminal in interference source community is greater than the minimum emissive power of setting, suppose that the transmitting power of the terminal in interference source community is greater than the minimum emissive power of setting, then continue adjustment according to the step-length 2dB of setting, now, the SNR of ascending edge user becomes 4dB, because 4dB is less than the threshold value 5dB of setting, then terminate the flow process adjusted.
Can finding out according to foregoing description, the uplink interference suppressing method that the embodiment of the present invention provides, by turning down the transmitting power of the terminal in interference source community, reducing interference source community to the interference being disturbed community.Compared with the prior art reducing presence of intercell interference with the frequency resource by multiplexed quadrature, the embodiment of the present invention reduces interference source community to the interference being disturbed community by the transmitting power turning down the edge termination in interference source community, the waste of frequency domain resource can not only be avoided, and power rationalization can also be carried out to whole bandwidth, thus reduce the interference of minizone.
Below by Fig. 3 and Fig. 4, respectively to be disturbed community send uplink interference information, and be disturbed community send uplink interference suppress instruction two kinds of modes under, uplink interference suppress idiographic flow be described in detail.
See Fig. 3, if be disturbed community send be uplink interference suppress instruction, then uplink interference suppress flow process can comprise:
S301, acquisition are disturbed the uplink interference suppression instruction that community sends.
S302, suppress instruction according to the uplink interference that community sends that is disturbed obtained, obtain interference source community and carry out the transmission information of the edge customer of uplink.
S303, carry out the transmission information of the edge customer of uplink according to interference source community, turn down the transmitting power of the edge termination in interference source community.
Wherein, in step S301, uplink interference information can be up low noise, can certainly can weigh the information of uplink interference degree for other.Be up low noise for uplink interference information, when being disturbed the up low noise of cell detection to this community and being greater than the up low noise threshold value of setting, think to there is high interference, then send uplink interference and suppress instruction; When being disturbed the up low noise of cell detection to this community and being less than or equal to the up low noise threshold value of setting, think to there is low interference, then do not send uplink interference and suppress instruction.Wherein, described up low noise threshold value can be arranged according to systematic function, also can be empirical value, such as this threshold value can be set to-110dBm.
The transmission information of the edge customer of uplink accessed in the specific implementation process of above-mentioned steps S302 and this step, identical with the step S102 in Fig. 1, no longer detailed explanation explanation is carried out to it at this.
The specific implementation process of above-mentioned steps S303 is identical with the step S102 in Fig. 1, also no longer carries out detailed explanation explanation to it at this.
Can find out according to foregoing description, be disturbed the uplink interference that community can receive according to this community and determine whether that starting uplink interference suppresses, and when determining that starting uplink interference suppresses, sending uplink interference suppresses instruction to adjacent cell, thus allow adjacent cell reduce the transmitting power of subscriber equipment, thus reduce adjacent cell as far as possible to the uplink interference being disturbed community.
See Fig. 4, if be disturbed community send be uplink interference information, then uplink interference suppress flow process can comprise:
S401, acquisition are disturbed the uplink interference information that community sends.Preferably, be disturbed community to detect according to setting cycle and concurrently send uplink interference information.
S402, according to the uplink interference information being disturbed community and sending, determine to be disturbed the uplink interference degree that community is subject to.
If S403 is disturbed the uplink interference degree that community is subject to exceed uplink interference suppression threshold, then go to step S404; Otherwise, go to step S405.
S404, obtain interference source community and carry out the transmission information of the edge customer of uplink, and carry out the transmission information of the edge customer of uplink according to interference source community, turn down the transmitting power of the edge termination in interference source community.
The transmitting power of the edge termination in S405, maintenance interference source community is constant.
Wherein, the uplink interference information in above-mentioned steps S401 can be up low noise, certainly also can be the parameter can weighing uplink interference degree of other type.
Uplink interference suppression threshold in above-mentioned steps S403 can be set to a thresholding, also can be set to two threshold values.
Be a first uplink interference suppression threshold for up AF panel thresholding, in step S403 ~ S405, can judge being disturbed the uplink interference degree that community is subject to according to the first uplink interference suppression threshold, concrete deterministic process is as follows: according to the uplink interference information being disturbed community and sending, determine to be disturbed the uplink interference degree that community is subject to; The uplink interference degree that community is subject to if be disturbed is more than the first uplink interference suppression threshold, show to be disturbed the uplink interference that community is subject to comparatively serious, then obtain the transmission information that the edge customer of uplink is carried out in interference source community, and the transmission information of the edge customer of uplink is carried out according to interference source community, turn down the transmitting power of the edge termination in interference source community; The uplink interference degree that community is subject to if be disturbed, more than the first uplink interference suppression threshold, shows to be disturbed the uplink interference that community is subject to not too serious, then keeps the transmitting power of the edge termination in interference source community constant.
The second uplink interference suppression threshold and the 3rd uplink interference suppression threshold is comprised with up AF panel thresholding, and the second uplink interference suppression threshold is greater than the 3rd uplink interference suppression threshold is example, in step S403 ~ S405, can judge being disturbed the uplink interference degree that community is subject to according to the second uplink interference suppression threshold and the 3rd uplink interference suppression threshold, the uplink interference degree that community is subject to if be disturbed is more than or equal to the second uplink interference suppression threshold, show that being disturbed community is subject to more serious uplink interference, then obtain the transmission information that the edge customer of uplink is carried out in interference source community, and the transmission information of the edge customer of uplink is carried out according to interference source community, turn down the transmitting power of the edge termination in interference source community, the uplink interference degree that community is subject to if be disturbed is less than or equal to the 3rd uplink interference suppression threshold, shows to be disturbed the uplink interference that community is subject to not serious, then keeps the transmitting power of the edge termination in interference source community constant.The uplink interference degree that community is subject to if be disturbed is between the second uplink interference suppression threshold and the 3rd uplink interference suppression threshold, then need to determine whether that starting uplink interference suppresses according to the transmission performance of the user in interference source community, particularly, obtain the transmission information that the edge customer of uplink is carried out in interference source community, determine the transmitting power of the edge termination whether turned down in interference source community according to the transmission information of the edge customer carrying out uplink in interference source community.
Concrete, carry out the upstream performance of the edge customer of uplink in the transmission information determination interference source community edge customer of uplink can being carried out according to interference source community; Some upstream performances of disturbing the edge customer carrying out uplink in cell-of-origin higher than setting threshold, then determine the transmitting power of the edge termination turned down in interference source community; Otherwise, keep the transmitting power of the edge termination in interference source community constant.Wherein, this threshold value can be arranged according to systematic function, also can be empirical value.
The specific implementation process of above-mentioned steps S404 is identical with the step S102 in Fig. 1, no longer carries out detailed explanation explanation to it at this.
Can find out according to foregoing description, in conjunction with the transmission situation of the UE within the scope of oneself and the situation that is disturbed being disturbed community, interference source community can determine whether that starting uplink interference suppresses, and judge whether that starting uplink interference suppresses by the mode arranging threshold value.When the degree that is disturbed being disturbed community is greater than the threshold value of setting, in conjunction with the transmission situation of the UE within the scope of oneself, interference source community can also determine that whether starting uplink interference suppresses, therefore, when ensureing the transmission performance of interference source community user as far as possible, interference source community also can be reduced as much as possible to the uplink interference being disturbed community.
