Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a power adjustment method, which is applied to a macro base station, wherein the macro base station calculates a power ratio for the macro base station according to the power of a small cell reported by each terminal; calculating the power ratio of each small cell according to the configured power adjustment value and the currently recorded transmission power of each small cell, and determining whether to update the transmission power of the small cell and the power ratio of the macro base station according to the calculated power ratio of the macro base station and the power ratio of the small cell; and determining whether to inform the updating of the transmission power or to re-rank each small cell according to the ratio of the small cell non-updating and calculating the ratio of the small cell non-updating again. The macro base station can effectively control the power of each small cell, so that the transmission power of each small cell is gradually optimized, and the network utilization efficiency is improved.
The macro base station distributes and updates the transmitting power for each small cell under the coverage of the macro base station; and the path loss and the same two or more power adjustment values are allocated to each small cell.
Assuming that under the coverage of the macro base station, there are a plurality of small cells C1,C2,...,CnThe initial transmission power allocated to each small cell is Pk，0≤Pk≤PmaxThe initial transmission power allocated to each small cell may be the same or different.
And the macro base station updates the currently recorded transmission power of the small cell if the macro base station determines that the transmission power of the small cell needs to be updated subsequently. If the transmission power of a certain small cell is updated for the first time, the allocated initial transmission power is updated.
The macro base station configures the same power adjustment value for each small cell, such as the power adjustment value delta ∈ { + -. delta1,±Δ2,...,±Δs}。
With multiple UEs, e.g. UEs, under the macro base station coverage1,UE2,...,UEmEach UE is connected to both the macro base station and one small cell, one small cell may be connected to multiple UEs, the UE connection to the macro base station is mainly responsible for some basic signaling transmissions, and the small cell is mainly responsible for large wireless data transmissions.
Referring to fig. 1, fig. 1 is a schematic flow chart of a power adjustment method according to an embodiment of the present invention. The method comprises the following specific steps:
step 101, the macro base station calculates through a network utility function according to the power of the small cell reported by each terminal, and obtains a power ratio for the macro base station.
The power of the small cell reported by the terminal is the product of the power of the small cell connected to the terminal and the path loss from the terminal to the small cell.
Suppose a UEiThe path loss from (1 < i ≦ m) to small cell k (1 < k ≦ n) is LikThen UEiReceived power of cell k is Iik＝Pk*Lik。
No matter which small cell the UE is connected to, the UE will report the power of 1 small cell, and for the convenience of description, the UE will be referred toiThe power received to cell k is denoted as Ii。
The step of calculating the power of the small cell reported by each terminal through a network utility function to obtain a power ratio for the macro base station comprises the following steps:
power ratio for the macro base station
Wherein,Iiis the reported power of the terminal i connected with the small cell, and m is the number of terminals reporting power.
And 102, the macro base station sequences all small cells covered by the macro base station according to a first preset rule, for any one of the sequenced small cells, according to the locally recorded current transmitting power of the small cell, and each power adjustment value and path loss configured for the small cell, the macro base station calculates through a network utility function respectively to obtain a power ratio which is the same as the number of the adjustment values, and selects the maximum power ratio as the power ratio of the small cell.
The first preset rule in this step may be according to usage configuration, and in a specific implementation, the first preset rule may be sorted according to cell numbers, names, and the like, where the sorting rule is defined so that when re-sorting is performed, the sorting result is different from the sorting result of this time, that is, when determining whether to notify the updated transmission power of each small cell, the small cells are sorted differently.
In this step, when each small cell is sorted, only when the UE connected to the small cell reports its power, the small cells are sorted, otherwise, there is no computational significance, and the small cells corresponding to the non-power reporting are not sorted.
And for each configured power adjustment value, performing product operation on the power obtained by summing the power adjustment value and the current transmission power of the small cell and the path loss configured for the small cell, and calculating through a network utility function according to the product operation result to obtain a power ratio corresponding to the power adjustment value.
In this step, taking the calculation of the power ratio of the kth small cell as an example, and the power of the kth small cell is reported by the terminal i, the specific steps are as follows:
let the power ratio F' (I) of the kth small celli)＝max{FΔ(Ii)}。
P herekThe current transmission power for the kth small cell, not necessarily the initial allocated transmission power for the small cell, only the transmission power of the small cell has not been updated, where PkThe macro base station allocates initial transmission power for the small cell.
Herein IiAnd the transmission power of the kth cell reported by the terminal i.
And delta is one of the configured power adjustment values, and is calculated for multiple times, and all the power adjustment values are traversed.
As currently ordered 3 small cells, there are respectively small cell a, small cell B and small cell C, and the current transmission power of each small cell is PA、PB、PCThe allocated path loss is respectively LA、LB、Lc. Power ratio of small cell a:
the power ratio of other small cells is calculated in a similar manner, and is not illustrated here.
103, the macro base station determines whether the power ratio of the small cell is greater than the power ratio for the macro base station, and if so, executes step 104; otherwise, step 105 is performed.
Step 104, the macro base station updates the power ratio for the macro base station using the power ratio of the small cell, and updates the transmission power of the small cell using the sum of the transmission power and the power adjustment value obtained from the power ratio of the small cell, and then executes step 106.
If F' (I)i) If the power ratio is larger than F, updating the power ratio of the macro base station to the power ratio of the small cell, and correspondingly updating the transmission power of the small cell.
The transmission power when the power ratio of the small cell is obtained is Pk+Δ1Updating the current recorded transmission power of the kth cell to Pk+Δ1。
Step 105, the macro base station maintains a power ratio for the macro cell and a transmit power of the small cell.
After the power ratios of all the small cells are calculated and the corresponding comparison processing is performed, step 106 is executed.
Step 106, when traversing all the small cells, the macro base station determines whether the percentage of the small cells without update exceeds a preset value, if so, step 107 is executed; otherwise, step 108 is performed.
The preset value is configured according to practical use, such as 80 percent.
Step 107, the macro base station notifies the corresponding small cells of the updated transmission power, so that each small cell performs transmission power update, and the process is ended.
Step 108, the macro base station reorders the small cells according to a second preset rule, and determines the percentage of the small cells without update again.
After the small cells are sorted by the second preset rule in this step, the sorting positions of the small cells are different from those of the small cells sorted by the first preset rule.
For example, in the first sequencing, the small cell 1 is sequenced to the small cell 10, and after the second sequencing, the small cell 2 is sequenced to the small cell 10 and then to the small cell 1; if a third ordering is required, small cell 3 may be ordered to small cell 10 to small cell 1 and small cell 2.
