Abstract: Systems and methods for efficient coordination in a network for power management are described. In particular, the system (for example, a radio unit) monitors a downlink traffic at the radio unit in the network, and determines a low traffic state of the radio unit. Further, the system identifies a power consumption policy for the radio unit to enter a low power state, and communicates the power consumption policy and a set of parameters associated with the power consumption policy to a distributed unit and/or a management unit via an M-plane or a C-plane communication. Further, the system receives an offset time from the distributed unit based on the set of parameters. The system applies the power consumption policy at the radio unit on completion of the offset time. Therefore, by selecting an appropriate mode of communication, the systems and methods enable efficient coordination in the network.

Abstract: Systems and methods for efficient power management in a wireless communication network are described. In particular, the system (for example, implemented at a radio unit) may monitor a downlink traffic at the radio unit in the wireless communication network. Further, the system may determine a low traffic state of the radio unit based on a pre-defined threshold of the monitored downlink traffic for a pre-configured time period. Furthermore, the system may configure the radio unit to enter a low power state based on the determined low traffic state. As such, the system may select a power consumption policy and apply the selected power consumption policy at the radio unit for efficient power management in the wireless communication network. Therefore, the radio unit may intelligently take decisions related to power consumption.
