Small Cell Resource Reconfiguration for Wireless Device Capabilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in dynamically allocating resources to optimize network operations due to varying device capabilities and quality of service (QoS) requirements, especially in small cells which lack the resources to support all enabled radio access technologies (RATs) and features simultaneously.
Innovation Solution
A scheduling entity, such as a small cell or base station, reconfigures its resources based on changes in device capabilities, QoS requirements, additions, or removals of wireless devices, using a processor and communication interface to autonomously adjust resource configurations, including frequency bands and carrier aggregations, without explicit requests from devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a small cell enables multiple RATs, bands, and features simultaneously, then network versatility and service capability are improved, but resource consumption and device complexity increase beyond what the small cell can sustain
Solution Approach 1:
The patent implements dynamic cell reconfiguration where the small cell base station continuously monitors device capabilities and QoS requirements, then adjusts enabled RATs, bands, and features in real-time. This dynamic adaptation allows the cell to provide high versatility when needed while maintaining manageable resource consumption by disabling unnecessary features when devices don't require them.
Solution Approach 2:
The system changes operational parameters (RAT types, frequency bands, feature sets) based on device capability reports and QoS requirements. By dynamically adjusting these parameters rather than maintaining fixed high-capability configuration, the small cell achieves adaptability without permanently incurring the resource costs of supporting all possible configurations simultaneously.
2Productivity
If a small cell dynamically reconfigures resources based on device capabilities, then resource utilization efficiency is improved, but system complexity and control overhead increase
Solution Approach 1:
The patent implements a feedback-driven reconfiguration mechanism where the small cell receives capability information and QoS requirements from devices, processes this feedback, and automatically adjusts resource allocation. This closed-loop feedback system enables efficient resource utilization by matching cell capabilities to actual device needs without requiring complex manual configuration or coordination.
Solution Approach 2:
The small cell base station autonomously performs reconfiguration based on received device information without requiring external control or manual intervention. The system serves itself by automatically monitoring, deciding, and executing resource allocation changes, which simplifies the control architecture while maintaining high resource utilization efficiency.
3Ease of operation
If a small cell maintains static resource configuration, then system complexity and control overhead are reduced, but adaptability to varying device capabilities and QoS requirements deteriorates
Solution Approach 1:
The patent employs preliminary action by having devices report their capabilities and QoS requirements in advance before actual service delivery. This allows the small cell to pre-configure appropriate RATs, bands, and features tailored to each device's needs, achieving both simplicity (automatic configuration based on pre-reported info) and adaptability (customized settings for different device types).

AI summary
Aspects of the present disclosure provide a scheduling entity and methods of operating the scheduling entity such that the scheduling entity reconfigures/allocates its resources based on device capabilities of the wireless devices. The scheduling entity utilizes a first resource configuration to provide communications service to one or more wireless devices associated with the scheduling entity. The scheduling entity determines a change of the one or more wireless devices, wherein the change include at least one of a capability change of a wireless device, a quality of service (QoS) requirement change of a wireless device, an addition of a wireless device, or a removal of a wireless device. Based on at least one of a predetermined time of a day or the determined change, the scheduling entity reconfigures to a second resource configuration to facilitate resource utilization of the first wireless cell.
