1. A method for uplink transmission in a 5G unlicensed band, comprising:
performing, by a terminal, listen before talk (LBT) on a scheduled resource to obtain a corresponding LBT result; wherein the LBT result comprises LBT success or LBT failure of at least part of the scheduled resource; and
transmitting, by the terminal, a transport block on the scheduled resource based on the LBT result;
wherein the transmitting a transport block on the scheduled resource based on the LBT result by the terminal comprises:
separately transmitting a first transport block and a second transport block on the scheduled resource based on the LBT result, first downlink control information (DCI), and an update time, wherein the update time is associated with the LBT result;
wherein the step of separately transmitting a first transport block and a second transport block on the scheduled resource based on the LBT result, the first DCI, and an update time comprises:
after determining that the LBT result indicates that LBT success of at least part of the scheduled resource, transmitting the first transport block in the first (n+i−1) slots in the scheduled resource; and
transmitting the second transport block in the (n+i)th to Nth slots in the scheduled resource; wherein n is the update time, i is the first slot in which sensing succeeds, N is the number of slots comprised in the scheduled resource, and n, i, and N are all integers.
