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.

Claim (Index 6):
The method according to  claim 1 , wherein the communication device is a User Equipment, UE, there is a second interval between start time of a signal transmission, and start time of the switching duration, wherein a length of the second interval is less than or equal to that of a preset interval of time, and more than or equal to a smallest length of guard.
