Abstract
Embodiments of the present disclosure relate to a method for listening-based transmission. The method is performed at a communications device of a first type with a plurality of beams and operable on an unlicensed spectrum. The method comprises identifying a beam direction for a communications device of a second type when there is data directed to the communications device of the second type and obtaining a backoff counter for the identified beam direction. The method also comprises selecting at least one beam direction for listening during. The beam in each of the at least one beam direction covers at least one communications device of the second type having data directed thereto. The method further comprises scheduling transmission to a communications device of the second type in the identified beam direction when the backoff counter corresponding to that beam direction reaches a certain threshold. Embodiments also relate to corresponding apparatus.
