Abstract: The present disclosure provides an information transmission method and device based on a sweeping block. The method includes: configuring part of or all symbols of a data transmission subframe within a sweeping period as a sweeping block; and carrying a sweeping signal channel in the sweeping block for transmission. The sweeping signal channel refers to a signal or a signal and channel to be transmitted by polling all ports or beams. The above solution can improve flexibility and efficiency of data beam transmission and reduce a latency of traffic transmission.

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.
