Dynamic Processing Resource Allocation for Uplink Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In small base stations like femtocells, the fixed allocation of processing resources to either standard or high-speed uplink channels is inefficient, as the number of users requiring high-speed or standard data services can vary significantly, leading to underutilization of resources and increased implementation costs.
Innovation Solution
Dynamic allocation of processing resources between high-speed and standard-speed data channel processing chains, allowing the same set of hardware to support different numbers of high-speed and standard-speed users based on demand, by controlling buffering and processing delays for each user.

Engineering Contradiction Analysis
1Adaptability or versatility
If processing resources are fixedly allocated to standard or high-speed data channels, then the system can support a predetermined number of users, but the hardware usage becomes inefficient when user demands vary
Solution Approach 1:
The patent implements dynamic allocation of processing resources by allowing the base station to reconfigure which processing chains handle high-speed versus standard data channels based on real-time user demands. The control processor dynamically assigns processing chains to different users depending on whether they require high-speed or standard service, enabling the system to adapt to varying numbers of users of each type without requiring separate fixed hardware allocations.
Solution Approach 2:
The patent makes processing chains universal by enabling the same processing chain to serve different functions - handling both high-speed and standard data channels depending on dynamic allocation. Instead of having dedicated hardware for each channel type, the processing chains can be flexibly assigned to support whichever channel type has higher demand at any given time, maximizing hardware utilization efficiency.
2Productivity
If separate processing modules are provided for standard and high-speed data channels, then each channel type can be processed efficiently, but implementation costs increase
Solution Approach 1:
The patent merges the processing capabilities for standard and high-speed data channels into a single integrated processing module rather than requiring separate dedicated modules. The processing chains are combined and dynamically allocated between the two channel types based on demand, eliminating the need for duplicate hardware and reducing implementation costs while maintaining efficient processing performance.
Solution Approach 2:
The processing chains are designed to be multi-functional, capable of handling both standard and high-speed data channels. This universality allows the same hardware to perform multiple functions, reducing the total amount of hardware required and lowering implementation costs while preserving the efficiency needed for both channel types through dynamic resource allocation.
3Device complexity
If the number of processing chains is fixed for standard data channels, then hardware design is simplified, but the system cannot adapt to varying user demands
Solution Approach 1:
The patent introduces dynamic allocation mechanisms that allow the base station to reconfigure processing chain assignments in real-time. The control processor monitors user demands and dynamically assigns processing chains to handle high-speed or standard data channels accordingly. This dynamic reconfiguration capability enables the system to adapt to varying numbers of users of each type while using a fixed physical hardware structure.
Solution Approach 2:
The patent changes the operational parameters of the processing chains through dynamic allocation control. By modifying which processing chains are assigned to high-speed versus standard channels based on real-time demand, the system can effectively adjust its capacity to support varying numbers of users. This parameter-level flexibility allows adaptation to changing user demands without requiring physical reconfiguration of the hardware.
