ENHANCED PHR REPORTING IN SUPPORT OF UE ANTENNA SCALING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17904808 titled 'ENHANCED PHR REPORTING IN SUPPORT OF UE ANTENNA SCALING

The present disclosure discusses devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device with at least one antenna array can activate or deactivate antenna elements to perform antenna scaling, generating a power headroom (PHR) report based on beamforming gains before and after scaling, and sending the report to a base station.

• Wireless device with antenna arrays can scale antennas by activating or deactivating elements.
• PHR report is generated based on beamforming gains pre and post antenna scaling.
• Report is sent to a base station for communication.

Potential Applications: - Improved performance in wireless communication systems. - Enhanced network efficiency and coverage. - Optimization of antenna resources for better signal reception.

Problems Solved: - Addressing challenges in antenna scaling for optimal performance. - Improving PHR reporting accuracy in wireless devices.

Benefits: - Enhanced signal quality and coverage. - Efficient use of antenna resources. - Improved overall network performance.

Commercial Applications: Title: Enhanced Wireless Communication Systems with Antenna Scaling Technology This technology can be applied in telecommunications, IoT devices, and 5G networks to optimize antenna performance and enhance signal quality for better user experience.

Questions about Antenna Scaling Technology: 1. How does antenna scaling improve wireless communication performance? Antenna scaling optimizes the use of antenna resources, leading to enhanced signal quality and coverage in wireless devices.

2. What are the key benefits of PHR reporting in antenna scaling technology? PHR reporting helps in accurately measuring the performance gains achieved through antenna scaling, enabling better network optimization and resource allocation.

Original Abstract Submitted

The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.
