Abstract: The present invention relates to a scheduling request transmission method, so as to effectively transmit a scheduling request when scheduling request resources are configured on multiple carriers. The terminal receives a configuration parameter for a scheduling request from a base station; when the scheduling request is triggered, the terminal sends the scheduling request on a selected one carrier of multiple carriers according to the configuration parameter. Scheduling request resources are assigned to the terminal on multiple carriers by sending the configuration parameter, so that the terminal can send the scheduling request on the selected one carrier of the multiple carriers according to the configuration parameter. This provides a solution to effectively transmitting the scheduling request.

Abstract: A user equipment obtains configuration information used to detect a received signal strength indicator (RSSI) value of a signal on an unlicensed frequency, samples the signal on the unlicensed frequency at a sampling interval included in the configuration information to obtain RSSI values of the signal on the unlicensed frequency sampled at sampling moments. The user equipment determines statistics on the RSSI values of the signal on the unlicensed frequency within a statistical window, obtains an RSSI value statistical result of the signal on the unlicensed frequency based on the statistics, and reports the RSSI value statistical result to a base station.
