POWER HEADROOM REPORTING FOR UPLINK CARRIER AGGREGATION COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17895805 titled 'POWER HEADROOM REPORTING FOR UPLINK CARRIER AGGREGATION COMMUNICATIONS

Simplified Explanation

    • Explanation:**

The patent application describes methods, systems, and devices for wireless communications, specifically focusing on uplink carrier aggregation communications. The user equipment (UE) is able to report power headroom for these communications, allowing for efficient transmission across multiple component carriers.

  • The UE receives a message indicating multiple component carriers are configured for communications.
  • The UE determines the available transmission power for uplink carrier aggregation transmissions across the multiple component carriers.
  • The UE transmits uplink messages using the determined transmission power via the component carriers.
  • The UE sends a power headroom report including a carrier aggregation power headroom parameter based on the transmission powers associated with the transmissions.
    • Potential Applications:**

1. Mobile telecommunications networks 2. Internet of Things (IoT) devices 3. Wireless broadband services

    • Problems Solved:**

1. Efficient utilization of multiple component carriers for uplink communications 2. Optimization of transmission power for carrier aggregation 3. Enhanced reliability and performance of wireless communications

    • Benefits:**

1. Improved data transmission speeds 2. Enhanced network capacity and efficiency 3. Better quality of service for users 4. Increased reliability of uplink communications.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may report power headroom for uplink carrier aggregation communications. The UE may receive a first message that indicates multiple component carriers are configured for communications at the UE. The UE may determine a first transmission power available for uplink carrier aggregation transmissions by the UE across the multiple component carriers during a transmission occasion. The UE may transmit one or more uplink messages associated with a second transmission power via one or more of the component carriers. The UE may transmit a power headroom report that includes a carrier aggregation power headroom parameter. A value of the carrier aggregation power headroom parameter may be based on the first transmission power and the second transmission power associated with uplink carrier aggregation transmissions via at least one of the multiple component carriers during the transmission occasion.
