In an exemplary embodiment of the present disclosure, as shown in fig. 9, a power compensation scheme of a remote radio unit at a base station side in an exemplary embodiment of the present disclosure includes:
in step S902, the newly added insertion loss obtaining module at the base station side may obtain the edge insertion loss condition of the RRU device filter in real time.
In step S904, in the intermediate frequency band, the insertion loss of the filter is relatively stable (here, a constant K can be assumed), and the ratio of P1 to P2 is calculated by K using the calculation formula of the insertion loss.
In step S906, the increase of the sideband insertion loss affects the value of the power P2, the affected value of P2 is denoted as P2', and the ratio of P1 to P2' is calculated from the increased insertion loss value.
In step S908, the ratio relationship between P2 and P2 'can be calculated from the ratio of P1 to P2 and the ratio of P1 to P2', and the percentage of power loss after the insertion loss is increased can be determined, so that the specific amount of power compensation can be further determined.
Step S910, after determining how much power needs to be compensated, the power can be increased as required to reduce the edge insertion loss, solve the sideband performance loss, improve the network environment and improve the user experience.
Specifically, the transmission power at the base station side can be calculated by the following formula:
P＝P out BTS-L dupl BTS-L P BTS+G a BTS+C ori formula (2)
Wherein P is out BTS is the output power of the base station originating system, L dupl BTS is loss in terms of period of combiner, duplexer, etc., L P BTS is loss of feed cable, jumper wire, joint and the like of the antenna, G a BTS is the gain of the base station transmit antenna, C ori Is the directional coefficient of the base station antenna.
The present disclosure adds a parameter P based on this equation (2) compensate To indicate the amount of power compensation required, the above equation (2) can be rewritten as equation (3) shown below:
P＝P out BTS-L dupl BTS-L P BTS+G a BTS+C ori +P compensate formula (3)
As shown in fig. 10, for P compensate The disclosure designs a calculation method for a filter insertion loss according to parameters, which comprises the following steps:
in step S1002, the stable Insertion Loss (IL) in the middle of the band is a, the edge insertion loss is b, and |b| > |a|.
Step S1004, calculatingAs a result of (2), P2 is determined.
Where IL is the insertion loss of the filter, P1 is the power when the filter is not accessed, and P2 is the power after the filter is accessed.
In step S1006, the values of a and b are substituted, p2=xp1, p2 '=yp1, and P1 is known, and P2' is determined.
In step S1008, the values of P2 and P2' are determined.
Step S1010, calculating P compensate Results of =p2-p2'.
Step S1012, calculating p=p out BTS-L dupl BTS-L P BTS+G a BTS+C ori +P compensate As a result of (a).
Step S1014, determining the value of the boosted power, thereby determining the boosted total transmit power.
Firstly, a newly added insertion loss acquisition module at the base station side can acquire the edge insertion loss condition of the RRU equipment filter in real time.
In the intermediate frequency band, the insertion loss of the filter is relatively stable (a certain value K can be assumed here), but there is a general problem that the insertion loss of the sidebands is relatively large, the value of the power P2 is affected, and the affected value of P2 is denoted as P2'. The ratio of the power P1 to the power P2' can be calculated by the above formula (P1 is a known value) by obtaining the value of the sideband insertion loss.
Thirdly, substituting the stable insertion loss value K of the intermediate frequency band, the ratio of P1 to P2 (P1 is a known quantity) can be calculated, and then P2 and P2' can be calculated, namely the quantity of power loss after the insertion loss is increased can be obtained, and the specific quantity of power compensation can be further determined, namely the parameter P is determined compensate 。
Further, after the power compensation is determined, the power can be increased as required to reduce the edge insertion loss, so that the sideband performance loss is solved, the problem of network coverage shrinkage is solved, and the user experience is improved.
In an exemplary embodiment of the present disclosure, taking an 11M bandwidth as an example, it is assumed that the transmission power p1=60W before the filter is inserted.
Step 1: in the middle of the frequency band, the insertion loss of the RRU device filter is stabilized to be about-2 dB. Thus, p2=38w can be calculated by using the insertion loss formula;
step 2: the newly added insertion loss acquisition module can acquire the assumption that the edge insertion loss of the RRU equipment filter is increased to-5 dB in real time, so that the power P2' =20W under the condition can be calculated by using an insertion loss formula;
step 3: from this, it can be known that the power loss P2-P2' =18w is caused by the increase of the edge insertion loss, resulting in 47% power loss;
step 4: therefore, it can be determined that 18W power compensation is needed, the transmitting power is increased by 18W, the edge insertion loss is reduced, and the sideband performance loss is solved.
The above embodiments are merely values that are conveniently drawn to illustrate technical details, and the embodiments of the present disclosure may be applied to all scenarios in which RRU filter devices cause power loss due to increased edge insertion loss.
