Carrier Scheduling for Scalable Wireless Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in supporting mobile stations that cannot demodulate the entire bandwidth, as existing systems struggle to efficiently allocate resources and update older network systems to accommodate new device capabilities.
Innovation Solution
A method and apparatus for scheduling access terminals in wireless communication systems, where terminals are assigned to communicate on one or multiple carriers based on their capabilities, using a processor to manage access requests and determine suitable carriers for transmission, allowing for efficient resource allocation and multi-carrier access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication systems allocate resources for entire bandwidth demodulation, then system capacity and throughput are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent divides the overall bandwidth into multiple component carriers, each with a smaller bandwidth that can be demodulated by devices with limited capabilities. This segmentation allows the system to support both high-capacity and low-complexity devices by allocating appropriate numbers of component carriers to different devices based on their demodulation capabilities.
2Adaptability or versatility
If wireless communication systems support multiple device capabilities, then adaptability is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal resource allocation framework where the same component carrier structure can serve multiple device types with different capabilities. The base station can allocate different numbers of component carriers to different devices, providing universal support for both full-bandwidth and partial-bandwidth demodulation devices without requiring separate system configurations.
3Adaptability or versatility
If wireless communication systems update network infrastructure, then new device capabilities are supported, but system cost and deployment difficulty increase
Solution Approach 1:
The patent implements a dynamic resource allocation approach where the base station can flexibly assign different numbers of component carriers to different devices based on their capabilities and current network conditions. This dynamic allocation allows the system to adapt to new device types without requiring infrastructure changes, as the same physical infrastructure can serve both old and new devices through software-controlled resource assignment.

AI summary
To support mobile stations that are not capable of demodulating the entire bandwidth or that can be made to demodulate less than the entire bandwidth, a system, apparatus and method are provided to schedule users on less than all of the bandwidth. Further, certain users can be scheduled on more of the bandwidth than others.
