Title:
TERMINAL AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/163153
Kind Code:
A1
Abstract:
This terminal comprises a control unit which determines a channel access mechanism on the basis of a condition, a reception unit which performs sensing on the basis of the determined channel access mechanism, and a transmission unit which performs transmission on the basis of the sensing result, wherein the determined channel access mechanism is listen before talk (LBT) in which a sensing period is fixed.
