Dynamic MAC Layer Resource Allocation via Multicast Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks inefficiently allocate MAC layer resources, leading to resource underutilization during inactive periods of communication sessions, and require significant processing and signaling overhead for granular allocation, which is costly and resource-intensive.
Innovation Solution
A method and system for dynamically allocating MAC layer resources by establishing a resource pool divided into physical layer allocation units for control and traffic data, using multicast grouping to reduce overhead and enhance resource efficiency, applicable to existing protocols like EV-DO and OFDM.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If MAC layer resources are allocated at the circuit level for the duration of a communication session, then resource allocation is simplified, but resource utilization efficiency deteriorates due to idle periods
Solution Approach 1:
The patent segments MAC layer resource allocation from circuit-level to packet-level granularity. Instead of allocating resources for the entire communication session, the system divides resources into smaller allocation units that can be independently assigned to individual packets. This segmentation enables dynamic allocation where resources are granted only when needed, eliminating waste during idle periods while maintaining manageable complexity through structured resource pool organization.
2Productivity
If MAC layer resources are allocated at the packet level for granular control, then resource utilization efficiency improves, but processing and signaling overhead increases
Solution Approach 1:
The patent merges multiple allocation decisions into unified resource pool structures. By organizing resources into shared pools that can be dynamically assigned to multiple users and services, the system reduces the total number of separate allocation signaling messages needed. The base station can serve multiple mobile stations from the same resource pool using consolidated scheduling decisions, thereby achieving fine-grained packet-level allocation while minimizing overhead through resource sharing and batched signaling.
3Productivity
If hardware is upgraded to support more efficient resource allocation, then resource utilization improves, but implementation cost and network outage time increase
Solution Approach 1:
The patent implements dynamic resource allocation through software-based scheduling mechanisms rather than requiring fixed hardware configurations. The base station uses dynamic scheduling algorithms that can adapt resource allocation in real-time based on traffic conditions, user priorities, and channel quality. This dynamic approach allows existing hardware to support efficient resource utilization through flexible software control, avoiding costly hardware upgrades and network disruptions while achieving improved resource utilization through intelligent allocation strategies.
