Abstract

The invention relates to a method, device and equipment for determining an accessible frequency point, and a readable storage medium. The method comprises the following steps: measuring frequency sweeping frequency points sequentially and periodically within each sampling time and obtaining a measurement result of each frequency sweeping frequency point within one sampling time; calculating a Received Signal Strength Indication RSSI mean value and Noise Index NI duty ratio of each frequency sweeping frequency point; and determining an accessible frequency point that meets a preset condition according to the RSSI mean value and the NI duty ratio of each frequency sweeping frequency point. According to the method, device and equipment for determining an accessible frequency point and the readable storage medium in the invention, the available frequency point can be selected from unlicensed frequency points and the supervision requirements anywhere can be met.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device, equipment and readable storage medium for determining an accessible frequency point. Background technique [0002] The 36.889 agreement gives the unlicensed frequency point division, usage and related regulations of 5150-5950MHZ in various countries. The set of available unlicensed frequency points, the combination of licensed frequency bands and unlicensed frequency bands that can be used for CA (Carrier Aggregation, Carrier Aggregation), and the carrier spacing between unlicensed carriers under CA. The requirements and usage of each frequency point are as follows: [0003] The frequency point 5150-5250MHz is used indoors. The maximum average EIRP (Effective Isotropic Radiated Power) is 200mW and the maximum average EIRP density is 10mW / MHz. On any 1M bandwidth or any 25kHz frequency point, 0.25mw / 25kHz; [0004] The frequency point 52...
