Description
Technical field
The present invention relates to communication technical field, relate in particular to power regulating method and the device of a kind of Remote Radio Unit (Radio Remote Unit, RRU).
Background technology
In Long Term Evolution (Long Term Evolution, LTE) system, to the covering in building, be very important.According to associated mechanisms prediction, the traffic carrying capacity in 4G stage (LTE) about 80% comes from indoor.Therefore, each is runed commercial city and is building energetically indoor distributed system, or improves degree of depth coverage condition, improves user satisfaction, promotes wireless network overall performance.
Solve indoor covering, existing two kinds of methods that often adopt comprise: indoor distributed system and outdoor compartment system.Indoor distributed system is for indoor user group, for improving a kind of successful scheme of mobile communication environment in building; Be to utilize domestic aerial compartment system that the signal of mobile base station is evenly distributed on to indoor every nook and cranny, thereby guarantee that room area has desirable signal and covers.Consistent with indoor distributed system in outdoor compartment system principle, be mainly used in building the covering of the building of indoor distributed system, antenna installation is outside the building covered indoor near building place, such as residential quarter etc.For avoiding producing stronger interference, these two kinds of methods all adopt the construction principle of " many antennas, small-power ", and antenna point is many, area coverage is large, and the loss of antenna-feedback system is also large, therefore need more Remote Radio Unit to cover.In traditional system, the corresponding Yi Ge of each Remote Radio Unit community, and the demand of LTE system to large bandwidth causes it to be difficult to inter-frequency networking as 2G, 3G system, a plurality of minizones are used the possibility of identical networking very large.Therefore, interference between a plurality of co-frequency cells will be very serious, cause system core parameter indication (Key Performance Indicator, KPI) index to worsen, systematic function declines, therefore, the method that indoor, outdoor compartment system often adopts community to merge, makes a plurality of Remote Radio Unit merge into Yi Ge community, expands community area coverage, reduce presence of intercell interference, reduce switching times.Community folding has become LTE and has solved the current techique that the indoor degree of depth covers.
But, in to the optimizing process of indoor covering, the environment of different building, different floors is likely all different, to the interference of other community in outdoor macro cell and building, be also different, therefore need to carry out targetedly power adjustment to different RRU, under the prerequisite not exerting an influence at the region performance that this RRU is covered, reduce the interference to other community.Therefore, often need to configure to different RRU different power.But adopt after the folding of community, by adjusting the method for cell power, can make all RRU allocating powers all change, can not reach and according to different environment, corresponding RRU be carried out the object of power adjustment, be not easy to indoor, outdoor compartment system coverage optimization.
In common merging community, community has a set of nominal power and demarcation amplitude, by OM, is configured to physical layer subsystem and RRU.Can only there be a transmitting power Yi Ge community, and broadcasts in system broadcasts, to notify the power information of current area.Therefore, the RRU power of same community must be consistent with cell power.If need to adjust the transmitting power that merges some RRU in community, and don't affect other RRU, prior art cannot configure to realize by software.
Suppose that certain building 1-6 layer is covered by 6 traditional communities, every layer is covered by one or more Remote Radio Unit.Because LTE adopts the whole network identical networking, therefore, each layer of minizone mutual interference is very strong.Therefore, change into 1 community is merged into in former 6 communities, by 1 community, cover a plurality of floors.Now, this community will have a plurality of RRU, and different RRU covers different floors.Because a plurality of RRU belong to Yi Ge community together, so the transmitting power of each RRU should be cell power, is identical.If give each RRU configuration a different power, be equivalent to current area to split into a plurality of communities, system will be safeguarded the data of a plurality of communities, the complexity that raising system is greatly realized.But in actual optimizing process, the power needing due to different regions is different, inevitably to adjust the transmitting power of each RRU, conventional method is to install attenuator additional in indoor subsystem, not only need engineering to execute more difficult, and increased construction cost, and coverage mode of the prior art, need to install attenuator additional at each Remote Radio Unit place, and by existing capacity of equipment, can support several even tens RRU to merge into Yi Ge community, above-mentioned method of adjustment need to expend a large amount of manpowers and resource.
For also often applying community folding in outdoor compartment system, the outdoor scene that the wire of highway etc. is covered also often adopts, can be by adjusting the angle of declination of antenna and the interference that azimuth reduces minizone in these scenes, but need engineering construction, cannot by adjusting the transmitting power of the RRU of a certain area covered, reduce interference as required.
In sum, in existing technical scheme, the method of adjusting chamber subsystem transmitting power mainly contains above kind, the one, the transmitting power of adjustment community, Zhe Huishigai community with the transmitting power of RRU all adjust, the requirement of adjusting for the power of certain floor, special scenes while being difficult to meet indoor coverage optimization.Another kind method is that chamber subsystem is transformed, and needs engineering construction, increase or change the attenuator in the subsystem of chamber, and long construction period, cost is high, has a strong impact on Optimization Progress.

Embodiment
The embodiment of the present invention provides a kind of power regulating method and device of Remote Radio Unit, in order to not affect under the realization of existed system and the prerequisite of performance, realize the transmitting power of adjusting more simply RRU, improve optimization efficiency, save a large amount of material costs and the workload of engineering construction.
The embodiment of the present invention can be configured and be adjusted respectively the transmitting power that merges each RRU in community by software with fairly simple method, makes the realization of existing system and performance unaffected simultaneously.
The embodiment of the present invention proposes by the OM passage of LTE system, the different RRUs of same community is configured to transmitting power after different adjustment and the corresponding relation of signal amplitude, reach the object that different RRU exports different power, do not affect function and the performance of system other side simultaneously.
The transmitting power of RRU is adjustable, in the adjustment of the dynamic range internal power of its support, does not affect its radio-frequency (RF) index.Base station is when setting up community, community nominal power and demarcation amplitude are configured to RRU, RRU is according to power and the amplitude of configuration, to passing through the unit based on bandwidth---baseband processing unit (Bandwidth Based Unit, BBU) data amplitude passing over converts, and with the power of expecting, sends data.Therefore,, as long as configure different nominal powers and demarcation amplitude to the different RRUs in same community, the different RRUs that can realize same community sends data with different power.
Referring to Fig. 1, BBU and RRU form distributed base station, and LMT is LMT Local Maintenance Terminal, is arranged on PC, for base station is configured, the operation such as maintenance.
Because BBU is when calculating amplitude, demarcation amplitude and the nominal power of Hui An community calculate, so the demarcation amplitude of each RRU needs and the demarcation amplitude of community is consistent.Therefore,, to changing the RRU of power output, can only change the configuration of its nominal power.OM in BBU, according to the index of this RRU, issues the OM in corresponding RRU by the nominal power after changing.
After community cloth has been joined, RRU transmitting power adjustment form of OM automatic cell generation of base station, nominal power comprising community, and the corresponding relation between RRU index and power adjustment, described power adjustment is that the transmitting power after adjusting deducts the value that described nominal power obtains, when the transmitting power of RRU is identical with the nominal power of community, this value is 0, can on LMT Operation and Maintenance circle, just like following table 1, similarly show:
Table 1RRU transmitting power adjustment form:
| The nominal power of community (dBm) | 46dBm |
| RRU index | Power adjustment (dB) |
| RRU0 | -1 |
| RRU1 | 0 |
| RRU2 | -3 |
Referring to Fig. 2, the adjustment RRU power method that the embodiment of the present invention provides, specifically comprises step:
201, determine the RRU that need to adjust transmitting power.
Particularly, on LMT Operation and Maintenance interface, user, by checking RRU transmitting power adjustment form, determine that the transmitting power of N RRU needs to adjust, and indication is to BBU.
202, the transmitting power adjusted value of N RRU is further set by this interface, for example, reduces 3dB, the transmitting power adjusted value that N RRU is set on this interface is-3, and indication is to BBU.
203, the OM of BBU can be according to the nominal power of community, and the transmitting power adjusted value of N RRU, calculates the nominal power value of this RRU, i.e. transmitting power after the adjustment of N RRU.
204, the OM of BBU judges whether the transmitting power after the adjustment of N RRU has surpassed the maximum power of RRU, and when surpassing RRU maximum power, execution step 207, points out power to go beyond the scope, and configuration does not come into force; Otherwise, execution step 205.
205, the OM of BBU configures the corresponding relation of the transmitting power after the adjustment of N RRU and signal amplitude to N RRU by OM passage.
206, by the transmitting power adjustment success of N RRU of LMT Operation and Maintenance interface prompt user.
207, by LMT Operation and Maintenance interface prompt power, go beyond the scope, the transmitting power adjustment of N RRU does not come into force.
N RRU is by the nominal power of new configuration, by the performance number of the transmit power transition Cheng Xin of base band data transmission.
It should be noted that, RRU power may cause the path loss measurement of UE to have deviation after revising.Because the transmitting power of community is broadcasted in system broadcasts, UE is according to the cell transmit power of receiving in broadcast, and the received power of actual measurement, calculates path loss.Path loss occurs that deviation can cause the up open loop of terminal to control definite power and difference appears in actual desired value.But because terminal is after access, up have a close-loop power control function, can carry out power adjustment fast by actual desired value, measure the impact that the deviation that produces produces system very little, can not consider.

Wherein, P_out_TX_nom and A_IQ_nom_TX are cell-level parameter, therefore, no matter have how many RRU in community, provide A after Base-Band Processing
xafter, by normal, realizing, the transmitting power calibration mapping of each RRU is identical, and the actual emission power of each RRU is also identical.And in embodiments of the present invention, in community, for each RRU sets up respectively a set of power calibration, shine upon, like this, although the A that Base-Band Processing provides
xidentical, but the real output of each RRU is not identical.For example:
Cell-level parameter configuration is:
A_IQ_nom_TX 8230；
P_out_TX_nom 6400（40W）；
After Base-Band Processing, provide Ax=4115 time, represent that power output is 20W, if but for some RRU, the mapping of its power calibration is as shown in table 3 below:
Table 3
| Name | internal unit | default value |
| A_IQ_nom_TX | 8230 | |
| P_out_TX_nom | 1/256dBm | 3200 |
