Carrier Aggregation Controller for Uplink Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems face challenges in achieving high uplink throughput rates, as they often rely on underutilized secondary carrier bands while primary carriers have low bandwidth, impacting Quality of Service (QoS) for client devices.
Innovation Solution
A carrier aggregation controller is employed to analyze resource allocation requests and metadata from various carriers, using machine-learning algorithms to determine optimal aggregation of intra-band, inter-band, or combined carrier components across Frequency Range 1 (FR1) and Frequency Range 2 (FR2) spectrum, adjusting Time Division Duplexing (TDD) ratios to balance resource utilization between uplink and downlink transmissions.

Engineering Contradiction Analysis
1Power
If carrier aggregation is used to improve downlink throughput, then downlink data rates increase, but uplink throughput remains limited by primary carrier bandwidth
Solution Approach 1:
The patent combines multiple carrier bands (both downlink and uplink carriers) into a unified carrier aggregation structure. By merging secondary carrier uplink resources with the primary carrier, the system enables uplink throughput to scale alongside downlink throughput, resolving the asymmetry where downlink benefited from aggregation but uplink remained constrained.
Solution Approach 2:
The system dynamically allocates carrier aggregation resources based on traffic demands. The base station can flexibly activate or deactivate secondary carriers for uplink transmissions depending on real-time conditions, allowing uplink throughput to adapt and improve without permanently over-provisioning resources.
2Productivity
If primary carrier bandwidth is increased to improve uplink throughput, then uplink QoS improves, but available bandwidth for other services decreases
Solution Approach 1:
The patent segments the uplink bandwidth into multiple carrier components instead of using a single wide primary carrier. This segmentation allows different carrier bands to be allocated to different services or users dynamically, enabling one service to receive enhanced uplink throughput while other services retain access to remaining bandwidth resources.
Solution Approach 2:
The carrier aggregation system creates a universal resource pool that can serve multiple functions and services. The same aggregated carrier resources can be dynamically assigned to different uplink transmissions based on demand, making the bandwidth infrastructure multi-functional and adaptable to various service requirements simultaneously.
3Productivity
If secondary carrier bands are utilized for uplink transmissions, then uplink throughput increases, but scheduling complexity increases
Solution Approach 1:
The base station acts as an intermediary that centralizes the scheduling complexity of multiple carrier bands. Rather than requiring complex distributed scheduling across multiple carriers, the base station consolidates the scheduling function, managing uplink resource allocation across aggregated carriers from a single point, thereby reducing overall system scheduling complexity while enabling multi-carrier uplink transmissions.

AI summary
This disclosure describes techniques that enable a carrier aggregation of two or more carrier available carriers for uplink transmissions at a base station node. More specifically, a carrier aggregation controller may receive a resource allocation request from a base station node that is associated with an uplink transmission of user plane data from a client device. The carrier aggregation controller may determine a carrier aggregation for the uplink transmission and generate scheduling information for delivery to the base station node that is based at least in part on the carrier aggregation.
