1. A user equipment (UE), comprising:
one or more transceivers;
one or more memories; and
one or more processors coupled to the one or more transceivers and the one or more memories, the one or more memories storing instructions that are executable by the one or more processors, individually or in any combination, to cause the UE to:
receive, from a network unit, a first communication signal in a first link direction during a channel occupancy time (COT) acquired by the network unit;
switch from the first link direction to a second link direction different from the first link direction;
receive, from the network unit via downlink control information (DCI), information for determining whether to perform a first listen-before-talk (LBT) procedure for the second link direction, wherein the DCI information includes an indication of a no LBT mode; and
transmit, to the network unit, a second communication signal in the second link direction during the COT without performing the first LBT procedure based on the DCI information and a transmission duration associated with the second communication signal satisfying a transmission duration threshold.
