Abstract
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.
Claims17
A method of transmitting information in an unlicensed band, applied to a network device side, comprising:
- performing listen before talk (LBT) at each candidate transmission position of a synchronized signal block until an LBT result of a channel indicates that the channel is idle, wherein the synchronized signal block comprises a New Radio primary synchronized signal (NR-PSS), a New Radio secondary synchronized signal (NR-SSS) and a New Radio physical broadcast channel (NR-PBCH) signal;
- sending, at the candidate transmission position of the synchronized signal block within a time domain transmission unit where the channel is idle, the corresponding synchronized signal block to user equipment (UE) if the LBT result of the channel indicates that the channel is idle, wherein the time domain transmission unit comprises at least two candidate transmission positions of the synchronized signal block.
A network device, comprising a processor, a storage and a computer program stored in the storage and executable by the processor, wherein, the processor is configured to execute the computer program, to implement following steps:
- performing listen before talk (LBT) at each candidate transmission position of a synchronized signal block until LBT result of a channel indicates that the channel is idle, wherein the synchronized signal block comprises a New Radio primary synchronized signal (NR-PSS), a New Radio secodary synchronized signal (NR-SSS) and a New Radio physical broadcast channel (NR-PBCH) signal;
- sending, at the candidate transmission position of the synchronized signal block within a time domain transmission unit where the channel is idle, the corresponding synchronized signal block to user equipment (UE) if the LBT result of the channel indicates that the channel is idle, wherein the time domain transmission unit comprises at least two candidate transmission positions of the synchronized signal block.
