Title:
DATA TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/054123
Kind Code:
A1
Abstract:
Disclosed in the present application are a data transmission method and device, solving the problem of using a dynamic uplink-downlink resource division manner for data transmission in a new wireless communication system. The method comprises: a terminal determining the start position of a time unit of the terminal, and determining the division of an uplink region and a downlink region in the time unit; the terminal detecting a downlink control channel in the downlink region of the time unit; and according to the detection result, the terminal performing an uplink transmission in the uplink region corresponding to the downlink region. As a terminal uses a time unit specific to the terminal for transmission, time units of different terminals may have different start positions, and the number and lengths of the uplink regions and/or downlink regions included in the time units of different terminals may also be different. Thus, the invention can support flexible and variable resource division.
