[0058] The example embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0061] Step S202, determining the transmission power at the base station side according to the output power, power loss and gain of the transceiver system at the base station side.

[0062] Step S204, determining the compensation power according to the power change of the filter of the remote radio unit before and after access.

[0063] Step S206, power compensating the transmission power according to the compensation power.

[0064] The embodiments of the present disclosure improve the reliability of the transmission power at the base station side by determining the transmission power at the base station side according to the output power, power loss and gain of the transceiver system at the base station side, determining the compensation power according to the power change of the filter of the remote radio unit before and after access, and then power compensating the transmission power according to the compensation power, and further ensure the communication reliability and interaction quality within the coverage network of the base station.

[0065] Next, each step of the power compensation method of the remote radio unit at the base station side is described in detail.

[0066] In an example embodiment of the present disclosure, as shown in Figure 3 Before determining the transmission power at the base station side according to the output power, power loss and gain of the transceiver system at the base station side, it further includes:

[0067] Step S302, determining the output power of the transceiver system at the base station side.

[0068] Step S304, determining the power loss at the base station side.

[0069] Step S306, determining the gain of the antenna at the base station side.

[0070] In an example embodiment of the present disclosure, as shown in Figure 4 determining the power loss of the base station side includes:

[0071] Step S402, determining the power loss of the antenna of the base station side, the power loss of the antenna including the loss caused by at least one of the factors of the feeder cable, the jumper and the joint.

[0072] Step S404, determining the power loss of the device of the base station side, the device including the combiner and / or the duplexer.

[0073] Step S406, determining the power loss of the base station side according to the power loss of the antenna and the power loss of the device.

[0074] In an example embodiment of the present disclosure, as shown in Figure 5 determining the gain of the antenna of the base station side includes:

[0075] Step S502, determining the transmitting gain of the antenna of the base station side.

[0076] Step S504, determining the directional coefficient of the antenna.

[0077] Step S506, determining the gain of the antenna according to the transmitting gain and the directional coefficient.

[0078] In an example embodiment of the present disclosure, the directional coefficient refers to the gain without loss, and the gain can be estimated according to the directional coefficient, i.e. the equation relationship of directional coefficient x efficiency = gain is satisfied.

[0079] In an example embodiment of the present disclosure, as shown in Figure 6 determining the compensation power according to the power change of the filter of the radio remote unit before and after access includes:

[0080] Step S602, determining the insertion loss of the filter, denoted as IL.

[0081] Step S604, determining the power before accessing the filter, denoted as P1.

[0082] Step S606, determining the initial power after accessing the filter according to the insertion loss, the power before accessing the filter and a preset algorithm, the initial power being denoted as P2.

[0083] Step S608, determining the power of the filter in the intermediate wave band according to the insertion loss, the power before accessing the filter and the preset algorithm, the power being denoted as P2'.

[0084] Step S610, determining the compensation power according to the initial power and the power of the intermediate wave band.

[0085] In an example embodiment of the present disclosure, the expression of the preset algorithm comprises:

[0086] IL=-10log(P1 / P2), formula (1).

[0087] In an example embodiment of the present disclosure, when the UUR device works in the intermediate frequency band, the insertion loss is denoted as IL', and the power before accessing the filter is unchanged, that is, IL'=-10log(P1 / P2'), based on which, the power P2' of the filter accessed in the intermediate wave band can be determined.

[0088] In an example embodiment of the present disclosure, as shown in Figure 7 the power compensation of the transmitting power according to the compensation power comprises:

[0089] Step S702, determining the power difference between the initial power and the power of the intermediate wave band.

[0090] Step S704, determining the power difference as the compensation power, and power compensating the transmitting power.

[0091] In an example embodiment of the present disclosure, as shown in Figure 8 with the increase of the bandwidth 800, there is higher insertion loss in the edge band of the bandwidth 800, which will greatly reduce the transmitting power of the RRU device, and in order to keep the transmitting power unchanged, the output power of the base station side needs to be increased for compensation.

[0092] In an example embodiment of the present disclosure, as shown in Figure 9 the power compensation scheme of the radio frequency remote unit of the base station side in the example embodiment of the present disclosure comprises:

[0093] Step S902, the newly added insertion loss acquisition module of the base station side can acquire the edge insertion loss of the filter of the RRU device in real time.

[0094] Step S904, in the intermediate frequency band, the insertion loss of the filter is relatively stable (herein, it can be assumed as a constant K), and the ratio of P1 to P2 is calculated by K using the calculation formula of the insertion loss.

[0095] Step S906, the increase of the edge band insertion loss will affect the value of the power P2, the affected P2 value is denoted as P2', and the ratio of P1 to P2' is calculated by the increased insertion loss value.

[0096] Step S908, the ratio of P2 and P2' can be calculated by the ratio of P1 and P2 and the ratio of P1 and P2', the percentage of power loss after the increase of the insertion loss is determined, and the specific amount of power compensation can be further determined.

[0097] Step S910, after determining how much power needs to be compensated, the power can be increased as needed to reduce the edge insertion loss, solve the performance loss of the edge band, improve the network environment, and improve the user experience.

[0098] Specifically, the transmission power of the base station side can be calculated by the following formula:

[0099] Formula (2)

[0100] Wherein, is the output power of the base station first launch system, is the loss of the combiner, duplexer and other periodical aspects, is the loss of the antenna feeder, jumper, joint and the like, is the gain of the base station transmitting antenna, is the directional coefficient of the base station antenna.

[0101] The present disclosure adds a parameter to represent the amount of power compensation needed on the basis of the above formula (2), and the above formula (2) can be rewritten as the following formula (3):

[0102] Formula (3)

[0103] As shown in Figure 10 , for the parameter, the present disclosure designs a calculation method, the calculation method of the filter insertion loss, comprising:

[0104] Step S1002, the stable insertion loss (IL) in the middle of the frequency band is a, the edge insertion loss is b, and |b|>|a|.

[0105] Step S1004, the result of calculating determines P2.

[0106] Wherein IL is the insertion loss of the filter, P1 is the power when the filter is not connected, and P2 is the power after the filter is connected.

[0107] Step S1006, a and b are substituted into P2=xP1 and P2'=yP1, P1 is known, and P2' is determined.

[0108] Step S1008, the values of P2 and P2' are determined.

[0109] Step S1010, calculate Pcompensate = P2 - P2' the result.

[0110] Step S1012, calculate the result.

[0111] Step S1014, determine the value of the power boost, thereby determining the total transmit power after the boost.

[0112] Firstly, the newly added insertion loss acquisition module on the base station side can acquire the edge insertion loss of the RRU device filter in real time.

[0113] Secondly, in the middle frequency band, the insertion loss of the filter is relatively stable (here it can be assumed to be a certain constant K), but there is a common problem of relatively large edge insertion loss, which will affect the value of power P2. The value of P2 after the influence is recorded as P2'. The value of the edge insertion loss obtained can be used to calculate the ratio of power P1 and P2' (P1 is a known quantity) through the above formula.

[0114] Thirdly, by substituting the stable insertion loss value K in the middle frequency band, a ratio of P1 and P2 (P1 is a known quantity) can also be calculated, and then P2 and P2' can be calculated, so that the amount of power loss after the increase of insertion loss can be obtained, and the specific amount of power compensation can be further determined, that is, the parameter .

[0115] Further, after determining how much power needs to be compensated, the power can be boosted as needed to reduce the edge insertion loss, solve the performance loss of the edge band, solve the problem of network coverage shrinkage, and improve the user experience.

[0116] In an exemplary embodiment of the present disclosure, taking 11M bandwidth as an example, it is assumed that the transmit power before the insertion filter is P1 = 60W.

[0117] Step 1: In the middle band, the insertion loss of the RRU device filter is stable at -2dB. Thus, P2 = 38W can be calculated by using the insertion loss formula;

[0118] Step 2: The newly added insertion loss acquisition module can acquire the edge insertion loss of the RRU device filter in real time, which is assumed to increase to -5dB. Thus, the power P2' = 20W under this condition can be calculated by using the insertion loss formula;

[0119] Step 3: It can be known that due to the increase of the edge insertion loss, the power is lost by P2 - P2' = 18W, which causes a power loss of 47%;

[0120] Step 4: Therefore, it can be determined that 18W of power compensation is needed, and the transmit power is increased by 18W to reduce the edge insertion loss and solve the performance loss of the edge band.

[0121] The above embodiments are only numerical values for illustrating technical details, and the embodiments of the present disclosure can be applied to all scenarios where the power loss is caused by the increased edge insertion loss of the RRU filter device.

[0122] Corresponding to the above method embodiments, the present disclosure also provides a power compensation device of a radio frequency remote unit on a base station side, which can be used to execute the above method embodiments.
