LISTEN-BEFORE-TALK METHOD AND APPARATUS

摘要

Disclosed are a listen-before-talk method and apparatus, the method comprising: determining a frequency domain distance between carriers or carrier sets; when the frequency domain distance is greater than a pre-set value, performing a listen-before-talk operation on the carriers or the carrier sets, respectively; and when the frequency domain distance is less than the pre-set value, performing the listen-before-talk operation on the carriers or the carrier sets synchronously. The present invention solves the problem that listen-before-talk cannot be performed when an unlicensed frequency band has a multi-carrier or a multi-carrier set in the prior art.
