SIGNAL PROCESSING METHOD AND RELEVANT DEVICE

摘要

A signal processing method and a relevant device. In the signal processing method, a user equipment can acquire configuration information for detecting a received signal strength indication (RSSI) value of a signal on an unlicensed frequency, wherein the configuration information comprises sampling parameter information corresponding to the signal on the unlicensed frequency and at least one statistical window, and the sampling parameter information comprises a sampling interval; the user equipment samples the signal on the unlicensed frequency at the sampling interval, and obtains RSSI values of the signal on the unlicensed frequency at various sampling moments; the user equipment collects statistics on the RSSI values of the signal on the unlicensed frequency at the various sampling moments comprised by the at least one statistical window, and obtains a statistical result of the RSSI values of the signal on the unlicensed frequency; and the user equipment reports the statistical result of the RSSI values of the signal on the unlicensed frequency to a base station. The present application can improve the accuracy of an RSSI value, according to which a base station serving a user equipment selects an idle unlicensed frequency.
