Smart overview of the Invention

The patent application outlines innovative apparatuses and methods to enhance carrier aggregation (CA) communications. This approach is designed to be adaptive, on-demand, and self-learning, addressing the increasing complexity of managing frequency band combinations in modern communication networks. The technology aims to improve the quality of service (QoS) and quality of experience (QoE) for users by intelligently selecting optimal frequency bands.

Background

Carrier aggregation was introduced with Long Term Evolution (LTE) to enable high-speed services by combining frequency bands. However, managing numerous band combinations, especially with the advent of 5G technology, poses significant challenges. The growing number of potential combinations can impact the efficiency of network operations and the user experience, necessitating more sophisticated solutions.

Methodology

The proposed system utilizes a mechanism where user equipment provides an index that corresponds to a set of frequency band combinations. The system determines the appropriate combination based on this index, optimizing the use of available bands for CA communications. If a device's index does not match known profiles, the system can generate candidate combinations or request additional information from other systems.

System Architecture

The communication network described includes various components such as access terminals, base stations, and switching devices. These elements work together to provide broadband, wireless, voice, and media access services. The network supports diverse technologies like DSLAMs, CMTSs, 4G/5G base stations, and VoIP gateways to facilitate comprehensive connectivity across different types of devices.

Applications

This technology is applicable across multiple sectors where efficient communication is critical. It enhances connectivity for mobile devices, data terminals, and telephony devices by optimizing the use of available network resources. By integrating various forms of access—broadband, wireless, voice—the system ensures robust service delivery tailored to the evolving needs of modern communication environments.
