Problems solved by technology

[0004] In the fifth-generation mobile communication system, a scenario that needs to be studied is a fast and low-cost control overhead information transmission method. The main problem of the commonly used solutions is that the transmission power of the terminal is not fully considered, which leads to the spectral efficiency of the system. How to increase the spectrum efficiency of the IoT system is an important problem to be solved urgently in the IoT system

Embodiment 1

[0026] Such as figure 1 As shown, the present invention discloses an information processing method based on signal-to-noise ratio in the Internet of Things. As Embodiment 1 of the present invention, the information processing method includes performing the following steps in sequence:

[0027] Step S1: The second communication node receives M pieces of first configuration information sent by the first communication node, and stores the first configuration information in a memory, the first configuration information includes a reference signal for path loss measurement, a minimum Receive signal-to-noise ratio, configuration information of three channel coding methods, configuration information of N access sequence groups, and configuration information of N data resources, where N is an integer greater than or equal to 1, and M is an integer greater than or equal to 2, so The configuration information of the above three channel coding methods are polar code, low density parity c...

Embodiment 2

[0037] Embodiment 2: On the basis of Embodiment 1, the number of subcarriers contained in the data resource is 3*512. This value is determined based on the characteristics of the physical network data packet after analysis, and can be applied to more than 90% of the IoT data structures.

Embodiment 3

[0038] Embodiment 3: On the basis of Embodiment 2, 1 / 3 of the subcarriers included in the data resources are used to transmit demodulation reference signals. Usually, the base station can use the access sequence sent by the terminal to perform channel estimation to demodulate the uplink data sent by the terminal. The advantage of adding demodulation pilots here is to improve the channel estimation accuracy of service data of a specific length that needs to be protected, thereby improving The transmission success rate of service data of this length.

Abstract

The present invention provides an information processing method, system, and storage medium based on signal-to-noise ratio in the Internet of Things. The information processing method includes: the second communication node receives M pieces of first configuration information sent by the first communication node, and converts the The first configuration information is stored in the memory, and the second communication node obtains the source data service bit sequence that needs to be sent to the first communication node; the second communication node is configured according to each set of first configuration information. The path loss is measured by the reference signal for path loss measurement, and the transmission power of each set of first configuration information is determined based on the sum of the path loss and the minimum received signal-to-noise ratio, and the second communication node selects the sum The corresponding first configuration information with the smallest value is used as candidate first configuration information. The beneficial effects of the present invention are: compared with the prior art, the present invention overcomes the problem of poor spectral efficiency in the existing Internet of Things, improves the spectral efficiency of the Internet of Things system, and reduces control overhead.
