Abstract

The invention provides a method, device and system for data scheduling and transmission. The method includes the following steps: configuring scheduling information according to a predetermined scheduling mode of unauthorized uplink subframes, he wherein scheduling information is used for indicating a terminal to perform transmission of uplink data on an unauthorized frequency spectrum; and receiving uplink data sent by the terminal according to the scheduling information. The problem of lack of technologies of reducing signaling overheads and improving an unauthorized frequency spectrum uplink transmission rate in related technologies causes reduced uplink data transmission efficiency is solved, and the effects of reducing signaling overheads and improving the unauthorized frequency spectrum uplink transmission rate are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data scheduling and transmission method, device and system. Background technique [0002] With the rapid growth of data services, the data transmission pressure on licensed spectrum carriers is also increasing. Therefore, using unlicensed spectrum carriers to share the data traffic in licensed carriers has become a follow-up Long Term Evolution (LTE) An important evolution direction of LTE) development. [0003] In the LTE / LTE-A system, DCI Format 0 and DCI Format 4 can be used for uplink scheduling. Downlink Control Information (DCI for short) mainly includes some scheduling configuration parameters, and the scheduling configuration parameters are generally divided into resource configuration parameters and transmission configuration parameters, wherein, the resource configuration parameters can specifically assign parameters to resource blocks, and the transmission configu...
