Abstract

The present invention provides a method, device and system for data scheduling and transmission. The method includes: configuring scheduling information according to a predetermined scheduling mode of unlicensed uplink subframes, and the scheduling information is used to instruct terminals to perform uplink data in unlicensed spectrum transmission; receive the uplink data sent by the terminal according to the scheduling information. It solves the problem that the efficiency of uplink data transmission is reduced due to the lack of technology to reduce signaling overhead and increase the uplink transmission rate of unlicensed spectrum in related technologies, thereby achieving the effect of reducing signaling overhead and increasing the uplink transmission rate of unlicensed spectrum .

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 for short). ) is an important evolutionary direction of 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 transm...
