Abstract: The present disclosure provides a data scheduling and transmission method, apparatus and system. The data scheduling method includes: configuring scheduling information according to a predetermined unlicensed-uplink-subframe scheduling mode, where the scheduling information is used for instructing a terminal to transmit uplink data on an unlicensed frequency spectrum; and receiving, according to the scheduling information, the uplink data sent by the terminal. This solves the problem of a reduced uplink data transmission efficiency due to a lack of a technology for reducing signaling overheads and improving an uplink transmission rate on an unlicensed frequency spectrum in the related art, thereby achieving effects of reducing the signaling overheads and improving the uplink transmission rate on the unlicensed frequency spectrum.

Abstract: An unlicensed carrier contention method and apparatus are provided. The method comprises that: a Licensed Assisted Access (LAA) device implements a Clear Channel Assessment (CCA) or an Evolution Clear Channel Assessment (eCCA) on a channel; if the result of the assessment is ‘idle’, the LAA device decrement N and determines whether or not the decremented N is greater than 0, wherein N is a natural number; and if the result of the determination indicates that the decremented N is not greater than 0, the LAA device uses an unlicensed carrier for data transmission. The disclosure addresses the problem that no contention withdrawal mechanism or procedure suitable for an LAA system is provided in the conventional art.
