Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The first node receives the first signaling; performing a first channel sensing operation on the first sub-band; and sending the first signal. Wherein the first signaling comprises first indication information, and the first indication information is used for indicating a receiving parameter of the first channel sensing operation; the first channel sensing operation is used for determining channel occupation information, and the channel occupation information is used for determining whether the first sub-band can be used for signal transmission by a sender of the first signaling; the first signal is used for indicating the channel occupation information; the first signaling is used for determining Q1 candidate resource groups, a first resource group is one of the Q1 candidate resource groups, and the first signal occupies the first resource group. According to the method, the receiving party of communication can execute the channel sensing operation and feed back the result, and interference caused by the hidden node problem is relieved.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission scheme and device related to unlicensed spectrum in wireless communication. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or Fifth Generation, 5G) to conduct research, passed the WI (Work Item, work item) of NR at the 3GPP RAN#75 plenary meeting, and started to standardize NR. [0003] One of the key technologies of NR is to support beam-based signal transmission. Its main application scenario is to enhance the coverage performance of NR devices working in the millimeter wave frequency band (su...
