In some aspects, the independent links ir) ot may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit GO receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a first TRP) via a first \"\") link and communicate with a third device (e.g., a second TRP) via a second link. In some scenarios, first channel sensing information 0 —. may be obtained for the first link and second channel sensing information may be obtained for the second link. In some aspects, a GC decision of whether to transmit via one or more of the links may be based on the channel sensing on one or more of the links. In some 1-1 c;;;;) cases, the links may be grouped together as a channel sensing group.
