In a shared spectrum network spatial LBT procedures are used for directionally targeting the channel reservation process. Prior to transmitting channel reservation signaling, the transmitter and receiver determine an effective interference considering available multiple input, multiple output (MIMO) configuration information. When the effective interference exceeds a predefined threshold, the node may without transmission of its channel reservation signal. Otherwise, when the effective interference remains within the threshold, each node's transmitted channel reservation signal may also identify at least a beamforming matrix either as payload or used to precode the node's channel reservation signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Asynchronous spatial LBT","description":"Improvements to asynchronous spatial listen before talk (LBT) procedures are disclosed.
