1. A method of wireless communication, comprising:
communicating, by a first wireless communication device with a second wireless communication device, a first downlink control information (DCI) associated with a first scheduled period, wherein the first scheduled period is associated with a gap period, wherein the first DCI indicates a first listen-before-talk (LBT) mode associated with the gap period;
communicating, by the first wireless communication device with the second wireless communication device during the first scheduled period, a first communication signal including a first silence period corresponding to the gap period;
communicating, by the first wireless communication device with the second wireless communication device before the first scheduled period, a second DCI associated with a second scheduled period after the first scheduled period, wherein the second scheduled period is associated with the gap period, and wherein the second DCI indicates a second LBT mode associated with the gap period, the second LBT mode being different from the first LBT mode; and
performing an LBT procedure during the gap period, wherein the LBT procedure is performed based on a selection of one of the first LBT mode or the second LBT mode, wherein the selection is based on a duration of the gap period.
