Dynamic Multi-Beam Resource Allocation in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-beam communication systems have fixed transmission resources, which cannot be adjusted to meet varying service requirements, leading to impracticality and poor user experience due to inflexible allocation of frequency-domain or time-domain resources.
Innovation Solution
A method and device that allow a network device to dynamically determine and adjust transmission resources for multiple beam groups based on service requirements, such as terminal device coverage, service type, or service volume, and communicate these changes to terminal devices through configuration information using dedicated signaling or broadcast channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmission resources for beams are fixed as specified by the communication system, then the system operation is simple and stable, but the system cannot meet diversified service requirements and has poor adaptability
Solution Approach 1:
The patent implements dynamic transmission resource allocation by allowing beams to switch between different resource sets (first resource set and second resource set) based on service requirements. The network device configures multiple resource sets and indicates which set each beam should use, enabling the system to adapt from fixed to flexible resource allocation without requiring complete redesign of the resource management framework.
Solution Approach 2:
The patent divides transmission resources into multiple resource sets (first resource set and second resource set) with different characteristics. Each beam can be assigned to different resource sets based on service requirements, such as using the first resource set for coverage-enhanced services and the second resource set for other services. This segmentation allows independent optimization of resources for different service types.
2Adaptability or versatility
If the same transmission resource is allocated to multiple beams, then the resource allocation is simple, but the system cannot meet different service requirements of different beams
Solution Approach 1:
The patent applies local quality by allowing different beams to use different transmission resources based on their specific service requirements. Each beam can be configured with appropriate resources locally optimized for its function - for example, coverage-enhanced beams use resources with repetition schemes while other beams use different resources. This local optimization is managed through beam-specific configuration indicators.
Solution Approach 2:
The patent changes resource allocation parameters dynamically by introducing multiple resource sets with different characteristics and allowing beams to switch between them. The network device can adjust which resource set each beam uses based on service requirements, effectively changing the resource allocation parameters without altering the fundamental system structure. This enables adaptation to diverse service types including coverage enhancement, high reliability, and low latency services.
3Adaptability or versatility
If transmission resources cannot be changed for beams, then the system operation is stable, but the system cannot meet changing service requirements leading to poor user experience
Solution Approach 1:
The patent implements dynamic resource allocation that allows the system to respond to changing service requirements in real-time. The network device can reconfigure which resource set each beam uses based on current service demands, enabling the system to adapt practically to varying requirements such as switching between coverage enhancement mode and normal operation mode without significant delay or service degradation.
