Abstract
A Channel Access Indicator (CAI) may be employed in New Radio Unlicensed (NR-U) to indicate channel occupation by a node to nodes outside its cell, indicate channel occupation by a node to nodes within its cell to aid spectral reuse, and to trigger a handshake between nodes within a cell to ensure that receiver has clear channel to transmit and receive.
