And the terminal reports the CSI to the gNB, and the gNB performs scheduling adjustment and related work of beam management according to the reported content. The gNB configures a proper CSI-RS (Channel state information reference signal) resource for the terminal, then the terminal measures the CSI-RS and calculates the required CSI, and finally reports the CSI to the gNB through a PUCCH (Physical Uplink Control Channel, Chinese: Physical Uplink Control Channel)/PUSCH (Physical Uplink Shared Channel, Chinese: Uplink Physical Shared Channel). In the CSI framework, one CSI-RS Resource CSI-Resource Config is used for configuring CSI measurement, and the other CSI is configured how to report CSI.
Referring to fig. 2, fig. 2 provides a communication method between an industrial personal computer and a controlled device, which may be performed in the industrial communication system as shown in fig. 1, and the method as shown in fig. 2 includes the following steps:
s201, an industrial personal computer acquires data to be communicated, and carries out category identification on the data to be communicated to determine whether the data to be communicated belongs to industrial control data;
step S202, when the industrial personal computer determines that the data to be communicated is industrial control data, calling an industrial coding mode (according to different controlled equipment, coding modes of different companies can be adopted, such as Toshiba coding, Siemens coding and the like) to execute industrial coding on the industrial control data to obtain a control signaling, and sending the control signaling to the controlled equipment through an industrial network;
and S203, when the industrial personal computer determines that the data to be communicated is non-industrial control data, calling a communication network coding (such as a coding mode of 5G or LTE) mode to execute network coding on the non-industrial control data to obtain communication data, and sending the communication data to the controlled equipment through a communication network.
According to the technical scheme, an industrial personal computer acquires data to be communicated, and carries out category identification on the data to be communicated to determine whether the data to be communicated belongs to control data; when the industrial personal computer determines that the data to be communicated is control data, calling an industrial coding mode to execute industrial coding on the control data to obtain a control signaling, and sending the control signaling to controlled equipment through an industrial network; and when the industrial personal computer determines that the data to be communicated is non-control data, calling a communication network coding mode to execute network coding on the control signaling to obtain communication data, and sending the communication data to the controlled equipment through the communication network. Therefore, different types of data can be transmitted through different networks, the reliability of network transmission is improved, and the communication efficiency is improved.
Industrial network data is generally divided into two types, one is industrial control data, such as control parameter adjustment (including but not limited to acceleration, deceleration, temperature, time, etc.), which is very high in reliability and time delay, but such data is generally small in size, generally tens of bits or hundreds of bits of data, and the other is non-industrial control data, such as operation parameters, operation states, mobile network signaling, etc., which is generally large or requires a complicated encoding method, and therefore needs to be transmitted through a mobile communication network.
Specifically, the industrial personal computer specifically may include: the directional antenna, the non-directional antenna and the processing unit can be provided with corresponding antenna matching circuits for matching the antenna, and the matching circuits can adopt the existing matching circuits, which are not described again.

For the directional antenna, the communication quality can be greatly improved at a correct angle, compared with a non-directional antenna, the communication quality can be improved, the best angle of the current communication is obtained by adjusting the angle, and for the industrial field, the controlled device is fixed in position (namely, the position does not move), namely, the position of the first controlled device is relatively fixed, but because interference can change, the best angle of the directional antenna can change within a range, so that the best angle can be determined through CSI report, and the communication quality can be improved.
Specifically, before sending the control signaling to the controlled device through the industrial network, the method may further include:
determining whether the control parameters of the control signaling are the same as the control parameters of the previous control signaling (for example, whether the control parameters are both temperature control signaling and rotation speed control signaling), and if the control parameters are the same, determining a difference value between a first value of the control parameter of the control signaling and a second value of the previous control signaling, wherein the control signaling carries the difference value.

That is, when the control signaling fails to be sent, the control signaling is sent through another communication network, specifically, the control signaling may be carried in a communication frame and sent to the controlled device, and specifically, the control signaling may be carried in a Payload (Payload) of the communication frame and sent.
