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.

A data transmission method and an apparatus relate to the communications field and are applied to data transmission to effectively reduce a collision reoccurrence probability after a device in a licensed-assisted access using Long Term Evolution (LAA-LTE) system preempts an unlicensed spectrum and collides with another device. A first device adjusts a detection moment or a quantity of detection times of clear channel assessment (CCA) of a channel in an unlicensed spectrum after the first device determines that the first device collides with another device when occupying the channel in the unlicensed spectrum to transmit data, and the first device occupies, according to an adjusted detection moment or an adjusted quantity of detection times of CCA of the channel in the unlicensed spectrum, the channel in the unlicensed spectrum to transmit data.
