SYSTEM AND METHOD FOR FAST BEAM TRACKING IN A CELLULAR ENVIRONMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17442456 titled 'SYSTEM AND METHOD FOR FAST BEAM TRACKING IN A CELLULAR ENVIRONMENT
Simplified Explanation
The abstract describes a patent application for methods and apparatuses that enable fast beam tracking in wireless communication. The patent application introduces a technique where a User Equipment (UE) informs a base station (gNB) about its capabilities for intra-symbol beam sweeping. The UE can assume that the intra-symbol beam sweeping configuration will be implemented or wait for a response from the gNB before implementing it. This process can occur during initial access or be dynamically updated during established communication.
- The UE signals its capabilities for intra-symbol beam sweeping to the gNB.
- The UE can assume or wait for a response from the gNB before implementing intra-symbol beam sweeping.
- The beam sweeping configuration can be dynamically updated by either the UE or the gNB during established communication.
- The UE can signal a desired change via its MAC CE, and the gNB can signal its change to the UE via DCI.
Potential Applications
- Wireless communication systems
- 5G and beyond networks
- Mobile devices and base stations
Problems Solved
- Inefficient beam tracking in wireless communication
- Lack of fast and accurate beam sweeping configuration
- Limited ability to dynamically update beam sweeping configuration
Benefits
- Improved beam tracking performance
- Faster and more accurate beam sweeping configuration
- Enhanced communication reliability and efficiency
Original Abstract Submitted
Methods and apparatuses are disclosed for performing fast beam tracking in a wireless communication environment. A UE signals to a gNB its capabilities for intra-symbol beam sweeping. Depending on configuration, the UE can either assume that the intra-symbol beam sweeping configuration will be implemented, or will await a response from the gNB before implementing intra-symbol beam sweeping. Although this is generally carried out during initial access between the UE and the gNB, the beam sweeping configuration can be dynamically updated by either the UE or the gNB during established communication. For example, the UE can signal a desired change via its MAC CE, and the gNB can signal its change to the UE via DCI.
