Dynamic Wireless Resource Allocation for Low-Latency Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently allocating resources for different types of communications, such as legacy, low latency, and low duty cycle communications, which require distinct round trip times and duty cycle timings, leading to inflexible resource management and potential bottlenecks.
Innovation Solution
The system identifies reserved resources for legacy communications and dynamically allocates remaining resources for other types of communications based on round trip time (RTT) and duty cycle timing, using semi-static and dynamic signaling to indicate available resources, allowing for flexible allocation and re-allocation of wireless resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resources are reserved for legacy communications, then legacy communication reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where resources initially reserved for legacy communications can be dynamically reassigned to low-latency or low-duty-cycle communications based on real-time network conditions and service requirements. This dynamic approach allows the system to adapt resource allocation flexibly, improving overall resource utilization while maintaining legacy service reliability through on-demand resource guarantee.
Solution Approach 2:
The system changes resource allocation parameters by introducing multiple communication types with different parameters (legacy, low-latency, low-duty-cycle) and allowing resource allocation parameters to be adjusted based on service type and network conditions. This enables the same physical resources to serve different communication requirements by changing allocation parameters rather than dedicating fixed resources.
2Adaptability or versatility
If resources are dynamically allocated for different communication types, then resource flexibility is improved, but system complexity deteriorates
Solution Approach 1:
The patent segments resources into different allocation pools or categories based on communication type requirements (legacy, low-latency, low-duty-cycle). This segmentation allows the system to manage complexity by treating different resource types separately while maintaining overall flexibility. Each segment can be managed with appropriate allocation strategies without affecting other segments.
Solution Approach 2:
The system implements universal resource blocks that can serve multiple communication types through configuration and signaling. Rather than creating separate dedicated resources for each communication type, the same physical resources can be configured to support different services, reducing overall system complexity while maintaining adaptability.
3Manufacturing precision
If semi-static and dynamic signaling is used for resource indication, then resource allocation precision is improved, but signaling overhead deteriorates
Solution Approach 1:
The system uses semi-static signaling to pre-configure resource allocations for different communication types before actual data transmission. This preliminary configuration establishes baseline resource reservations and allocation patterns, reducing the need for frequent dynamic signaling adjustments. The semi-static setup provides a framework that guides subsequent dynamic allocations with minimal overhead.
Solution Approach 2:
The patent implements periodic updates of resource allocation signaling rather than continuous signaling. Semi-static configurations are updated at predetermined intervals or events, and dynamic adjustments are made periodically based on scheduling opportunities. This periodic approach maintains allocation precision while significantly reducing signaling overhead compared to continuous real-time signaling.

AI summary
Methods, systems, and devices are described for providing allocations and signaling for different types of communications within a wireless communication system. An eNB and/or a UE may be configured to operate within the wireless communication system using two or more different types of communications. The different types of communications may differ, for example, based on round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, a transmission time interval (TTI) for wireless transmissions, and/or duty cycle timing of wireless transmissions. Reserved resources within a system bandwidth may be identified for a first type of communications, and all or a portion of remaining resources within the system bandwidth may be allocated for other communications that may differ from the first type of communications based on, for example, RTT, TTI, and/or duty cycle timing.
