BACKWARD COMPATIBLE METHODS FOR SIGNALING ENERGY-SAVING SLEEP MODES OVER O-RAN FRONTHAUL INTERFACE

A control plane signaling method for reducing energy consumption of O-RAN radio units used in O-RAN CUS and including an O-DU controlling an O-RU via control-plane messaging where a sleep period is extended using a 16-bit binary number that is formed by two reserved octets in Section Type 0, or via...

Summary:A control plane signaling method for reducing energy consumption of O-RAN radio units used in O-RAN CUS and including an O-DU controlling an O-RU via control-plane messaging where a sleep period is extended using a 16-bit binary number that is formed by two reserved octets in Section Type 0, or via an inactivity timer is used to trigger transitions between different sleep states and active states, or via a bitmap formed by a reserved octet in Section Type 0 and is used to signal the O-RU to directly transition to different sleep modes.
