Abstract: Optical networks and nodes are described herein, including an optical network comprising a head-end node and a tail-end node. A line module of the head-end node receives fault information, generates a fault packet, and sends the fault packet to a first node controller identified by first packet forwarding information included in a packet header of the fault packet. The first node controller retrieves second packet forwarding information using the first packet forwarding information, updates the packet header, and sends the fault packet to the tail-end node identified by the second packet forwarding information. A second node controller of the tail-end node retrieves third packet forwarding information using the second packet forwarding information, updates the packet header, and sends the fault packet to an optical protection switching module (OPSM) of the tail-end node identified by the second packet forwarding information. The OPSM switches an optical switch based on the fault information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, capability signaling indicating one or more phase coherency capabilities of the UE for maintaining phase coherence across multiple uplink messages within a time interval, wherein each phase coherency capability is based on one or more channel usage characteristics associated with the time interval. The UE may receive, from the base station, a downlink message scheduling a set of uplink messages from the UE to the base station within the time interval. The UE may transmit the set of uplink messages within the time interval based on the downlink message and in accordance with at least one of the one or more phase coherency capabilities.
