When the data transmission device 302 is a remote unit device, data interaction may be performed between the CPRI interface or the eccri interface and the aggregation unit device. The remote unit device may include: a power source 401, a Central Processing Unit (CPU) 402, a digital intermediate frequency unit 403, a clock port (CLK) 404, a fiber transceiver (transceiver) 405, a Wi-Fi module 406, and a plurality of antenna interfaces (ANTs).

In an implementation manner, the data transmission apparatus may receive a request message sent by a data sending end for requesting to transmit original data. Wherein, the request message includes initial signal parameters.

S1002, the data transmission device determines whether a value of the initial signal parameter and a difference between the values of the interference parameter are within a preset interference range.

The interference parameter is a parameter corresponding to the initial signal parameter in the control information.

Illustratively, in the control information, the corresponding interference parameter, i.e., the transmission frequency of the Wi-Fi signal, is 2.4 ghz. The interference range of the preset frequency is [ -0.1G, +0.1] G Hz of the emission frequency of the Wi-Fi signal,

when the data transmission device obtains the value of the initial signal parameter of the original data a, the value includes: when the transmitting frequency is 2.3 GHz, the data transmission device determines that the difference is-0.1 GHz and is in the interference range.

When the data transmission device obtains the value of the initial signal parameter of the original data B, the value includes: when the transmitting frequency is 2.2 GHz, the data transmission device determines that the difference is-0.2 GHz and is not in the interference range.

And S1003, when the difference value is in the interference range, the data transmission device adjusts the initial signal parameter to obtain a target signal parameter.

In connection with the above example, in the case where the data transmission apparatus determines that the difference corresponding to the original data a is in the interference range, the data transmission apparatus adjusts the transmission frequency to be 2.2 ghz. Since the adjusted difference is-0.2 GHz and is not in the interference range, 2.2 GHz is determined as the target signal parameter.

And S1004, when the difference value is not in the interference range, the data transmission device determines the initial signal parameter as the target signal parameter.

In connection with the example in S1002, the data transmission apparatus determines that the difference corresponding to the original data B is not in the interference range, so 2.2 ghz is determined as the target signal parameter.

S1005, the data transmission device transmits the target data based on the target signal parameter.

With reference to the example in S1003 or S1004, the data transmission device transmits the target data corresponding to the raw data a or the raw data B at 2.2 ghz.

The technical scheme provided by the embodiment at least has the following beneficial effects: from S1001 to S1005, after the data transmission device obtains the initial signal parameter of the original data, it can be determined whether the value of the initial signal parameter and the difference between the values of the initial signal parameter and the interference parameter are within the preset interference range. When the difference is within the interference range, the data transmission device may adjust the initial signal parameter to obtain the target signal parameter. When the difference is not in the interference range, the data transmission device may determine the initial signal parameter as the target signal parameter. The data transfer device may then transmit the target data based on the target signal parameter. Therefore, the target signal parameters of the data transmission device for transmitting the target data do not have interference parameters in the network, and the signal interference problem of the fusion equipment is solved.
