The error message may include the timing of the error within the configured time window, e.g., whether the error occurred at the beginning or end of the configured time window. The error message may further indicate the cause of the error, such as failure to receive a PRS processing window, or that the PRS had low priority relative to downlink signals or channels.

Abstract: A proxy sensing-based channel access procedure is discussed for shared spectrum networks. Within a given network, a distribution of proxy nodes may be deployed around a network operating area. A control node, which controls the proxy sensing mode for the network, may configure the active network nodes to conduct communications via the shared communication spectrum without first performing any type of channel sensing on the shared communication spectrum. The control node may then also configured the proxy nodes to perform channel sensing on the shared spectrum for the entire network. Using the reported channel sense results from the proxy nodes, the control node may determine whether detected interference is occasional or persistent, and whether to take some action to modify the communications or operations of the network.
