[0048] In this embodiment, a signal receiving method of a radio remote unit is provided. The radio remote unit includes a radio frequency transmitting component and a radio frequency receiving component. The processing component of the base station or the repeater is connected to both the radio frequency transmitting component and the radio frequency receiving component. The radio frequency receiving component includes a link controller and a radio frequency receiving link. The link controller is connected to the radio frequency receiving link. The radio frequency receiving link is also connected to the output end of the radio frequency transmitting component. The method is applied to the link controller. Figure 2 1 is a flow chart of a signal receiving method of a radio remote unit according to an embodiment of the present application, the flow comprising the following steps:

[0049] Step S202, detecting a current signal transmission state of the radio remote unit, wherein the signal transmission state is used to indicate whether the radio frequency transmission component is currently transmitting a downlink signal, where the downlink signal is a signal transmitted by the radio remote unit to a terminal within a service range of the radio remote unit;

[0050] Step S204, when it is detected that the signal transmission state indicates that the RF transmission component is currently transmitting a downlink signal, the link parameter of the RF receiving link is set to a target link parameter, wherein the target link parameter is used to indicate the degree of signal conversion of the received initial function signal by the RF receiving link;

[0051] Step S206, controlling the RF receiving link to receive the initial function signal from the output end, wherein the RF receiving link is used to convert the initial function signal into a target function signal and transmit the target function signal to the processing component, and the target function signal is used to instruct the processing component to adjust the downlink signal.

[0052] Through the above steps, since a link controller connected to the RF receiving link is deployed in the RF remote unit, the link controller detects the current signal transmission state of the RF remote unit, and when the signal transmission state is detected to indicate that the RF transmitting component is currently transmitting a downlink signal, the link parameter of the RF receiving link is set to a target link parameter indicating the degree of signal conversion of the received initial function signal by the RF receiving link, and then the RF receiving link is controlled to receive the initial function signal from the output end of the RF transmitting component, and the RF receiving link will convert the initial function signal into a target function signal for instructing the processing component to adjust the downlink signal, so that the RF receiving link for receiving the uplink signal of the RF remote unit can be reused for the reception of the RF remote unit function signal, simplifying the complexity of realizing the signal receiving function of the RF remote unit and improving the signal receiving efficiency of the RF remote unit. The above technical solution solves the problem of low signal receiving efficiency of the RF remote unit in the related art, and achieves the technical effect of improving the signal receiving efficiency of the RF remote unit.

[0053] Optionally, in the embodiment of the present application, the radio frequency remote technology includes but is not limited to being applied to a base station or to a repeater, and the base station or the repeater may include but is not limited to the aforementioned radio frequency remote unit.

[0054] Optionally, in an embodiment of the present application, the radio frequency transmission component of the radio frequency remote unit can be used, but not limited to, to send a downlink signal to a terminal within the service range of the base station / repeater (also referred to as the service range of the radio frequency remote unit). Since the transmission of the downlink signal by the base station / repeater may require a long transmission process, which will cause the stability of the downlink signal sent by the base station / repeater to deteriorate, it is necessary to detect the corresponding functional signal to adjust the downlink signal sent by the base station / repeater to improve the stability of the signal. In addition, the mismatch between the transmission channel of the signal and the signal will lead to a relatively poor transmission efficiency of the signal. In order to improve the transmission efficiency of the downlink signal of the base station / repeater, it is also necessary to detect the functional signal related thereto (also referred to as the feedback signal) to improve the transmission performance of the downlink signal of the base station / repeater. For the reception of the functional signal, if the corresponding receiving link is established to receive it, more hardware devices will be added to the radio frequency remote unit, resulting in an increase in the complexity of the signal reception of the radio frequency remote unit and low signal reception efficiency. However, through the method in the present application, a link controller is added to the RF receiving component, and the original RF receiving link for receiving uplink signals is reused. When the RF transmitting component is transmitting a downlink signal, the uplink signal is not transmitted, and the RF receiving link is idle. During this period, the RF receiving link is used to receive the functional signal, which can reduce the difficulty of signal reception while ensuring that the RF transmitting and RF receiving functions of the RF remote unit are normally realized, thereby improving the signal reception efficiency of the RF remote unit.

[0055] Optionally, in an embodiment of the present application, the RF transmitting component may be used, but is not limited to, to convert the baseband signal output by the processing component into a RF signal and transmit it externally. The RF transmitting component may be used, but is not limited to, to include multiple signal converters and a signal transmitter. The signal converter may be used, but is not limited to, to include filters, amplifiers, attenuators, tuners, or digital-to-analog converters and other devices. The signal transmitter may be used, but is not limited to, to include antennas and other devices.

[0056] Optionally, in the embodiment of the present application, the RF receiving link may be, but is not limited to, used to receive RF signals and convert the received RF signals into digital signals for transmission to the processing component, which further processes the received signals. The RF receiving link may be, but is not limited to, including antennas and devices such as filters, amplifiers, attenuators, tuners, or analog-to-digital converters.

[0057] In the technical solution provided in the above step S202, detecting the current signal transmission state of the radio remote unit includes but is not limited to determining by detecting whether an uplink signal is being received on the radio frequency receiving link.

[0058] The base stations / repeaters involved in the present application may be, but are not limited to, base stations / repeaters that utilize TDD (Time Division Duplexing) channel time division multiplexing technology. The base stations / repeaters that utilize the channel time division multiplexing technology will utilize the RF receiving link and the RF transmitting link (components) to complete the reception of uplink signals and the transmission of downlink signals in different time periods of a time cycle. Figure 3 FIG. 1 is a schematic diagram of a signal receiving and transmitting ratio scheme of a radio remote unit according to an embodiment of the present application. Figure 3As shown in the figure, taking a common 10MS (millisecond) single-cycle 5GNR (5th Generation New Radio, fifth generation new wireless technology) configuration as an example, its TDD-NR uplink and downlink ratio is DDDDDDDSUU, where D stands for downlink subframe, U stands for uplink subframe, and S stands for special subframe. The special subframe includes three parts: downlink pilot time slot (DwPTS), guard period (GP) and uplink pilot time slot (UpPTS). DwPTS is used for downlink synchronization, UpPTS is used for uplink synchronization, and GP is used to prevent interference between downlink signals and uplink signals, providing time isolation for uplink and downlink transmissions on the same frequency performed by the TDD system. When the TDD-NR special subframe configuration is 6:4:4, in a 10-ms period, 7.429 ms are used to send downlink signals through the RF transmitting component, 2.285 ms are used to receive uplink signals through the RF receiving link, and 2.285 ms are idle time.

[0059] Optionally, in an embodiment of the present application, the above-mentioned signal period, uplink and downlink ratio within the period, and special subframe configuration may be stored in a link controller but is not limited to being stored. The link controller may be able to determine the situation of the signal currently being transmitted by the radio frequency remote unit through the signal period, uplink and downlink ratio, and special subframe configuration, thereby realizing the detection of the signal sending status.

For example, the link parameters may include the amplification factor of the amplifier, which is used to indicate the signal amplification function of the amplifier in the RF receiving link, etc.

For some functional devices in the RF receiving link, the functional parameters may be set within a range that meets both the reception requirements of the uplink signal and the reception requirements of the functional signal. When switching between the two modes of receiving the functional signal and receiving the uplink signal, such functional devices do not need to be processed.

[0062] Optionally, in an embodiment of the present application, the link parameters of the RF receiving link are set to target link parameters, including but not limited to determining the currently received first function signal based on the reception order of the multiple function signals when the initial function signal includes multiple function signals, querying the first link parameter corresponding to the first function signal from the correspondence between the function signal and the link parameter, and setting the link parameters of the RF receiving link to the first link parameter; when the reception order indicates that the reception time of the first function signal is exhausted, that is, the reception time of the second function signal arrives, querying the second link parameter corresponding to the second function signal from the correspondence between the function signal and the link parameter, and setting the link parameters of the RF receiving link to the second link parameter, wherein the multiple function signals include the first function signal and the second function signal, and the target link parameters include the first link parameter and the second link parameter.

[0063] Optionally, in an embodiment of the present application, the link parameters of the RF receiving link are set as target link parameters, and it is also possible but not limited to detecting the current link parameters of the RF receiving link. When it is detected that the current link parameters match the initial functional signal, the original link parameters are kept unchanged; when it is detected that the current link parameters do not match the initial functional signal, the link parameters of the RF receiving link are adjusted to the target link parameters that match the initial functional signal.

Figure 5 is a schematic diagram of a periodic signal transmission setting of a radio frequency receiving component according to an embodiment of the present application, which can be used as follows Figure 5 The time distribution diagram shown in the figure can make full use of the RF receiving components, that is, the RF switch can be switched to the feedback channel of the pre-distortion function or the standing wave reflection link. The feedback signal of the pre-distortion function (5 milliseconds) and the reflection signal of the standing wave detection function (2.429 milliseconds) use the RX RF link for 7.429 milliseconds. The uplink signal of 5GNR occupies the other 2.285 milliseconds of the 10 milliseconds. At the same time, these three signals can be sent to the power amplifier PA through a three-selection RF switch, and one of the signals can be selected to be received using the RX RF link at a specific time stage.

[0080] The solution provided in this application can not only meet the signal reception requirements of the uplink signal reception function, pre-distortion function, and standing wave ratio detection function of the 5GNR high-power RRU equipment, but also realize the sharing of an RX RF link through a three-in-one RF switch, which can further save the resources of the hardware RF link, thereby reducing the hardware cost of the equipment and the complexity of the RF link.
