Provided are a method of transmitting information in an unlicensed band and a network device. The method includes: when there is a synchronized signal block to be transmitted, performing listen before talk (LBT) at an LBT position of a time-domain transmission unit where a candidate transmission position of the synchronized signal block is located, to obtain an LBT result of a channel; if the LBT result of the channel indicates that the channel is idle, then sending, at the candidate transmission position of the synchronized signal block, the corresponding synchronized signal block to UE.
