Abstract: A method for reporting a failure report and a related device are provided. The method includes: determining reporting signaling in a case that an uplink Listen-Before-Talk (LBT) failure occurs on a terminal in at least one cell; and sending failure information of the at least one cell to a network side based on the reporting signaling. In the method for reporting a failure report, in a case that the LBT failure occurs in the at least one cell, the terminal can quickly report failure information to the network side, so that the network side can restore the uplink LBT failure in a timely manner, to prevent the terminal from continuously triggering a connection reestablishment process.

Abstract: A method for data transmission, a data reception method, and a device are provided. The method includes: in a case that a first data packet has been generated based on a first uplink grant and uplink transmission corresponding to the first uplink grant is given up, determining, according to a selection rule, a second uplink grant for transmitting the first data packet. In the method of the embodiments of this disclosure, the terminal device can autonomously select an uplink grant for transmitting a data packet corresponding to a discarded uplink grant, thereby avoiding data loss.
