POWER HEADROOM REPORTING FOR DYNAMIC POWER AGGREGATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17542255 titled 'POWER HEADROOM REPORTING FOR DYNAMIC POWER AGGREGATION
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on improving power management in wireless communication networks. Here is a simplified explanation of the abstract:
- A user equipment (UE) receives control signaling from a base station indicating a time interval to determine available power headroom relative to a transmission power threshold.
- The UE calculates the available power headroom by considering its transmission power during the specified time interval.
- The UE transmits a power headroom report to the base station in an uplink transmission, indicating the calculated available power headroom.
- The base station uses this information to schedule uplink messages at the UE based on the available power headroom.
Potential Applications
This technology has potential applications in various wireless communication networks, including:
- Cellular networks: It can be used to optimize power management in 4G and 5G networks, ensuring efficient resource allocation and improved network performance.

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling, such as a control message or radio resource control (RRC) signaling, from a base station indicating a time interval over which to determine available power headroom relative to a transmission power threshold. The UE may calculate the available power headroom relative to the transmission power threshold as a function of UE transmission power during the time interval. The UE may transmit a power headroom report in an uplink transmission to the base station, the power headroom report indicating the calculated available power headroom. The base station may schedule one or more uplink messages at the UE according to the available power headroom.
