Dynamic Modem Throughput Throttling for Shared UE Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modem control techniques in wireless communication systems are deficient in managing shared resource usage among components of user equipment (UE), leading to degraded user experiences due to limited resource availability for other components like cameras or WLAN devices.
Innovation Solution
The UE identifies a throttling indicator for a shared resource, such as memory bandwidth, and adjusts the modem configuration based on a throttling level to reduce resource usage below a usage threshold, ensuring greater availability for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If modem throughput is increased to improve communication performance, then data transmission speed is improved, but shared resource usage increases causing degradation of other components' performance
Solution Approach 1:
The patent implements dynamic modulation and coding scheme (MCS) selection based on channel conditions and quality of service (QoS) requirements. The system continuously adapts the modem's transmission parameters including modulation order, coding rate, and resource allocation to optimize throughput while controlling shared resource consumption. This dynamic adjustment allows the modem to achieve high throughput when channel conditions permit while reducing resource usage when other components need shared resources.
Solution Approach 2:
The system changes key transmission parameters such as modulation scheme (QPSK, 16-QAM, 64-QAM, 256-QAM), coding rate, and transport block size based on channel quality indicators and QoS requirements. By varying these parameters, the modem can adapt its resource consumption to match actual communication needs, preventing excessive shared resource usage while maintaining adequate throughput.
2Quantity of substance
If shared resource allocation is optimized for other components, then availability for cameras and WLAN devices is improved, but modem throughput decreases
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors channel conditions, QoS requirements, and shared resource usage in real-time. Based on this feedback, the modem dynamically adjusts its transmission parameters and resource allocation. When other components require shared resources, the feedback loop triggers parameter changes in the modem to reduce its resource consumption, thereby maintaining overall system performance while ensuring resource availability for concurrent operations.
Solution Approach 2:
The system employs dynamic resource allocation where the modem's resource usage is continuously adjusted based on real-time system conditions. The scheduler dynamically determines resource allocation for different components including the modem, cameras, and WLAN devices, ensuring that shared resources are allocated efficiently according to current needs rather than static pre-allocation, thus preventing throughput degradation while maintaining availability.
3Device complexity
If conventional modem control techniques are used, then implementation simplicity is maintained, but resource management efficiency deteriorates
Solution Approach 1:
The patent integrates multiple functions into a unified resource management framework that handles both modem control and shared resource allocation simultaneously. The scheduler and parameter adjustment mechanisms serve dual purposes: optimizing modem throughput and managing shared resource distribution to other components. This multi-functional approach improves resource management efficiency without proportionally increasing system complexity, as the same control structures serve multiple objectives.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a throttling indicator for a shared resource associated with a modem at the UE. The CE may determine a configuration of the modem based on a configuration received from a Radio Resource Control layer of the UE. Based on the modem configuration and the throttling indicator, the UE may identify a throttling level to apply to the modem. The UE may adjust the modem configuration for communicating with a base station based on the throttling level in order to reduce resource usage below a usage threshold. By reducing usage of the shared resource by the modem, the UE may have a greater availability of the shared resource to meet the needs of other components of the UE. This may provide an improved user experience at the UE, among other benefits.
