Virtual Cluster Group Uplink Control Channel Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation wireless communication networks face challenges in efficiently allocating time-frequency resources for uplink control channels due to limited spectrum availability, necessitating innovative methods to enhance bandwidth utilization and prevent collisions between scheduled entities.
Innovation Solution
The implementation of virtual cluster groups (VCGs) for uplink control channels, where each VCG comprises uplink clusters mapped to specific physical tones, allows for efficient allocation and assignment of time-frequency resources, preventing tone overlap and enabling effective communication between scheduling and scheduled entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum resources are allocated for uplink control channels in traditional wireless networks, then basic communication functionality is maintained, but bandwidth utilization is inefficient and collisions occur between scheduled entities
Solution Approach 1:
The patent divides the uplink control channel resources into multiple virtual cluster groups (VCGs), where each VCG contains specific uplink clusters mapped to particular physical tones. This segmentation allows different scheduled entities to be assigned to different VCGs, enabling efficient bandwidth utilization while preventing collisions through dedicated resource allocation.
2Adaptability or versatility
If flexible bandwidth allocation is implemented to meet data speed requirements, then network flexibility improves, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic bandwidth allocation by allowing the scheduling entity to flexibly assign different numbers of VCGs to different scheduled entities based on their specific data speed and latency requirements. The system can adapt resource allocation in real-time while maintaining manageable complexity through the structured VCG framework.

AI summary
Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.
