Wireless communications systems and methods related to performing listen-before-talk (LBT) before a transmission after a link switch in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device receives, from a second wireless communication device, a first communication signal. The first wireless communication device determines a first measurement period in a first portion of a gap duration between the first communication signal and a second communication signal, the first portion being adjacent to a start time of the second communication signal. The first wireless communication device performs an LBT based at least in part on a first channel measurement in the first measurement period. The first wireless communication device transmits, to the second wireless communication device, the second communication signal based on the LBT.
