Abstract: Embodiments of the present disclosure relate to a solution for supporting an LBT mechanism for sidelink transmissions. In a method for communication, a terminal device starts a listen-before-talk (LBT) procedure. The terminal device generates an LBT failure indication if a channel for a side Link transmission is occupied during the LBT procedure.

In this way, the sidelink transmission associated with the terminal device can coexist with other transmissions based on other wireless technologies, for example, on an unlicensed band.
