Title:
DATA TRANSMISSION METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/024563
Kind Code:
A1
Abstract:
A data transmission method, device, and system are provided, resolving a problem of meeting a latency requirement of a client service on a basis of a transmission mechanism employing a transmission time interval (TTI) of one subframe or one millisecond (ms). In one embodiment of the invention, the base station comprises: a processing module configured to determine a data transmission resource of a short TTI data transmission resource having a length in a time domain and less than one subframe or less than one millisecond; and a transceiver module configured to transmit, to terminal equipment, downlink control information (DCI) indicative of a data transmission resource, and perform, using the data transmission resource, a data transmission between the base station and the terminal equipment. Employing the short TTI data transmission resource as the data transmission resource can decrease a transmission time interval, increase a number of times of scheduling with respect to a terminal equipment in a unit time, effectively reducing data transmission latency.
