CHANNEL STATE INFORMATION (CSI) FOR UNLICENSED SPECTRUM

Abstract: this disclosure provides systems, methods, and apparatuses for the identification of a channel state information reference signal (csi-rs) resource. in some aspects, a network entity transmits configuration information indicating a plurality of csi-rs resources. the network entity selectively transmits the csi-rs on a selected csi-rs resource based on a channel access operation and the configuration information. the network entity then selectively receives a csi report based on the csi-rs. signaling or techniques for when no csi-rs is detected (such as when the network entity fails a channel access operation for all available csi-rs resources) are also provided. additionally, approaches for rate matching shared channels around csi-rs resources or managing csi interference (csi-im) are disclosed, as well as csi reporting approaches for scenarios when the user equipment (ue) fails to transmit csi feedback due to a failed channel access operation, including triggered or re-triggered csi reports.
