通信方法及装置
By performing a listen-before-speak LBT on the beam set that occupies the channel time in multi-beam communication, and by combining the first LBT and the second LBT, the problems of excessively long LBT time before transmission and inter-beam blocking are solved, achieving more efficient channel detection and resource utilization.

AI Technical Summary
Technical Problem
In unlicensed frequency bands for multi-beam communication, the LBT process before transmission takes too long, leading to severe blocking problems between different beams.
Method used
The beam set during the channel occupancy time is subjected to a listen-before-speak LBT, which includes a first LBT and a second LBT. At least one beam is detected by the first LBT. The time domain resources of the first LBT are less than those of the second LBT, thus reducing the time domain resources of the LBT before transmission.
Benefits of technology
By performing short LBTs on partial beams, the need to perform full LBTs on all beams is reduced, the LBT time before transmission is lowered, and the congestion problem between different beams is alleviated.

Abstract
本申请提供一种通信方法及装置，方法包括：对信道占用时间中的波束集合的每个波束通过先听后说LBT进行信道检测，LBT包括第一LBT和第二LBT，其中，所述波束集合中的至少一个波束通过第一LBT进行信道检测。通过该方式，由于对波束集合中的部分波束进行行第一LBT的信道检测，可以不必对所有波束执行完整的第二LBT的信道检测流程，进而可以减少传输前的LBT的时域资源，减轻不同波束间阻塞的问题。
