The every other embodiment obtaining, broadly falls into the scope of protection of the invention.
Fig. 1 is the flow chart of cell power collocation method embodiment one of the present invention, the execution master of the present embodiment
Body is rru, as shown in figure 1, the method for the present embodiment may include that
Step 101, Remote Radio Unit rru send described rru to indoor baseband processing unit bbu and prop up
The maximum transmission power held.
Specifically, itself, after being connected with bbu by electrical interface or optical interface, can be supported by rru
Maximum transmission power is sent to bbu, and the maximum transmission power that this rru supports is determined by the hardware of this rru,
For example, 10w.
Step 102, described rru receive the configuration information of at least one cell that bbu sends, described little

Specifically, the first attainable mode, bbu sets up multiple cells by described rru, to institute
State the configuration information that rru sends each cell, and the transmission power sum in the configuration information of each cell is more than
The maximum transmission power that described rru supports.The transmitting work(of each cell under a rru is configured by bbu
Rate sum is more than the maximum transmission power that this rru supports, each cell can be identical standard can also be not
Same standard, rru allows bbu to set up the corresponding cell of configuration information of each cell, is so in order to every
The power of individual cell leaves the space dynamically shared.For example it is assumed that n cell is set up on rru,
According to common power distribution method, bbu can be respectively configured transmission power pn to this n cell, and (n takes 1
To n), the maximum transmission power that wherein rru supports is pmax, then the n cell that rru sets up
Penetrating power needs to meet equation below (1).
Sum (p1～pn)≤p max, (1)
Wherein sum () is summing function, based on such configuration mode, with cell 1 explanation for example,
The maximum of cell 1 transmission power under high loads is p1max≤p max-sum (p2～pn).
And use the present embodiment cell power configuration mode it is assumed that bbu using the present embodiment mode to
It is pn ' that n cell is respectively configured transmission power, then the transmission power of the n cell that rru sets up meets public affairs

When penetrating power, if remaining a need for setting up cell, rru still allows new cell to set up.Work(when cell
When rate demand difference is larger, the cell power collocation method using the present embodiment is logical with respect in prior art
Normal power distribution method, can lift offered load by way of allowing to set up new cell, thus
Realize dynamic power to share.
For example, according to common collocation method, bbu configures transmission power to respectively cell a and b
ForWithRru sets up cell a and cell b according to configuration information, then when cell a
When load is higher, then due to configuring the restriction of transmission power, cell a can not obtain more transmission powers,
And use the cell power collocation method of the present embodiment then so that cell a obtains more transmitting work(
Rate, specifically, according to the cell power collocation method of the present embodiment, when cell a load is higher, and little
In the case of area's b load is low-down, bbu, according to loading condition, can send new cell c to rru
Configuration information, and for this cell c transmission power beRru can allow to set up new cell c,
Offered load is lifted by this cell c.

The restriction of the transmission power of cell, when the collocation method using above-mentioned cell power, each cell of configuration
Transmission power sum is more than the maximum transmission power that described rru supports, and the actual emission power of each cell
Sum is not necessarily more than the maximum transmission power that described rru supports, but, when the reality of each cell is sent out
When penetrating the maximum transmission power that power sum is more than described rru support, the hardware of described rru can be caused
Damage, therefore, described rru needs whether the actual emission power sum judging each cell is more than described rru
The maximum transmission power supported, if so, then described rru carries out power to the actual emission power of each cell
Compression is processed.I.e. it should be understood that through above-mentioned steps 102 and step 103, when the power of cell needs
When asking difference larger, so that obtaining certain power the cell of high load capacity, thus realizing dynamic work(more
Rate is shared, and that is, the power of itself is shared to the cell of this high load capacity by the cell of underload, however, work as should
When the load of the cell of underload raises to a certain extent, the actual emission power of each cell on rru it
With the maximum transmission power that will exceed this rru support it is therefore desirable to be processed using above-mentioned power compression,
