Title:
TERMINAL AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/089778
Kind Code:
A1
Abstract:
A terminal comprising a control unit that determines a time point for starting certain transmission in a unlicensed band, the time point being a start or an intermediate of a section set for inter-terminal direct communication in a unit time, a reception unit that executes the listen before talk (LBT) in an LBT channel for the transmission, and a transmission unit that starts, when the LBT is successful, the transmission to another terminal at the determined time point, wherein the control unit determines, when a certain condition is satisfied, that the transmission is to be started at the intermediate of the section.
