FIELD: communications.
SUBSTANCE: invention relates to the field of communications. The device determines one of at least two channel access mechanisms as the target channel access mechanism based on the duration of the time domain resource occupied by the signal, the size of the subcarrier spacing, the number of reference signals contained in the signal, the signal priority and interference situation in the direction of signal transmission. In this case, the device determines that the target channel access mechanism is the first type of channel access mechanism when the duration of the time domain resource occupied by the signal is less than or equal to the first time duration; and / or that the target channel access mechanism is a second type of channel access mechanism when the duration of the time domain resource occupied by the signal is greater than the first time duration, and wherein the first time duration is 1 millisecond; wherein the first type of channel access mechanism is channel sounding with a specific sounding duration, and the second type of channel access mechanism is channel sounding based on the contention window.
EFFECT: technical result of the invention is to select an appropriate channel access mechanism based on the duration of the time domain resource occupied by the signal.
