Overhead Reduction for Multi-carrier Beam Selection and Power Control - A simplified explanation of the abstract

This abstract first appeared for US patent application 17916850 titled 'Overhead Reduction for Multi-carrier Beam Selection and Power Control

Simplified Explanation

The patent application describes a method for reducing overhead in multi-carrier beam selection and power control for wireless communication systems. Here are the key points:

• The user equipment device (UE) receives an uplink beam configuration for a group of component carriers and uses it to communicate.
• The UE can receive an updated uplink beam configuration for the group of component carriers.
• The updated configuration includes a medium access control (MAC) control element (CE) that updates the pathloss reference signal for the group of component carriers.
• The MAC CE also includes information about the spatial relation for aperiodic or semi-persistent sounding reference signals, transmission control indicator for a physical downlink control channel, update for a physical uplink shared channel, and update for a sounding reference signal.

Potential applications of this technology:

• Wireless communication systems that use multi-carrier beam selection and power control.
• Mobile devices and base stations that support advanced beamforming techniques.
• Networks with high data traffic and multiple component carriers.

Problems solved by this technology:

• Reduces overhead in multi-carrier beam selection and power control.
• Improves the efficiency and reliability of wireless communication systems.
• Enables better utilization of available spectrum and resources.

Benefits of this technology:

• Enhanced performance and capacity of wireless networks.
• Improved signal quality and coverage for mobile devices.
• Reduced interference and increased spectral efficiency.
• Better support for high-speed data transmission and low-latency applications.

Original Abstract Submitted

Apparatuses, systems, and methods for overhead reduction for multi-carrier beam selection and power control. A user equipment device (UE) may receive an uplink beam configuration for a group of component carriers and may communicate using the uplink beam configuration for the group of component carriers. The UE may receive an updated uplink beam configuration for the group of component carriers. The update uplink beam configuration may include a medium access control (MAC) control element (CE) that may update a pathloss reference signal for the group of component carriers. The MAC CE may include an indication of a spatial relation for aperiodic or semi-persistent sounding reference signals for the group of component carriers, an indication of a transmission control indicator for a physical downlink control channel, an indication of an update for a physical uplink shared channel, and/or an indication of an update for a sounding reference signal.
