Abstract: The present invention discloses a data transmission method and device configured to address the problems in LTE-U employing the existing channel access mechanism, in which poor channel access capacity is caused, and congestion between UEs in the same cell is likely to occur if multiple UEs cannot access at the same time. The method comprises: sending, by a communication device, a signal during a GP between a downlink subframe and an uplink subframe to occupy a current channel; and transmitting, by the communication device, data via the current channel. The solution provided in embodiments of the present invention has low implementation complexity, and can address the problem of UL having a poorer opportunity to access than WIFI, thus facilitating the implementation of MU-FDM and MU-SDM to prevent significant degradation of LAA performance and a waste of radio resources.

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.
