Abstract
A listening method and device are provided. In the method: a sending node, on the basis of a beam direction used by the sending node for sending data to a receiving node, determines at least one listening direction to be listened to; the sending node implements carrier listening in the at least one listening direction; and, on the basis of the listening results in the at least one listening direction, the sending node uses the beam direction to send data to the receiving node.
Claims17
A sensing method, comprising:
- sending, by a receiving node, configuration information to a sending node, the configuration information being used to indicate sensing information used by the sending node for carrier sensing,
- wherein the sensing information comprises at least one of:
- at least one sensing direction, a sensing sequence of different sensing directions, or information of sensing windows corresponding to different sensing directions, and
- the at least one sensing direction is determined by the sending node according to a beam used by the sending node for sending data to the receiving node;
- wherein carrier sensing on the at least one sensing direction is performed until it is determined through sensing that a channel in the at least one sensing direction is idle.
