Abstract

The invention provides an LAA scheduling method and apparatus. In a first step, UE receives first signaling and second signaling, the first signaling indicates a first sub frame of a first carrier to be configured as a first structure, and the second signaling indicates a first COT on the first carrier. In a second step, the UE determines whether the first sub frame belongs to the first COT, and if the first sub frame belongs to the first COT, a first operation will be performed; and if the first sub frame does not belong to the first COT, a second operation will be performed. The first carrier is deployed to an unlicensed spectrum. As an example, the first operation is to receive a wireless signal on the first sub frame of the first carrier and the second operation is to assume that a service cell maintains zero transmit power on the first sub frame of the first carrier and the first structure is a downlink sub frame.
