Dynamic Retransmission Resource Allocation in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in dynamically allocating retransmission resources efficiently, leading to increased latency and reduced reliability in communications between base stations, controllers, and devices, especially in industrial IoT applications where low latency and high reliability are critical.
Innovation Solution
The method involves determining an estimated total amount of resources for retransmissions across the wireless network and dynamically allocating these resources based on the total number of original transmissions, rather than statically allocating resources for each link, allowing for efficient retransmission of failed communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If static resource allocation is used for each link, then resource allocation is simple and predictable, but network resource consumption increases and retransmission efficiency decreases
Solution Approach 1:
The patent merges resource allocation from multiple individual links into a centralized pool managed by a controller. Instead of each link having dedicated static resources, resources are aggregated and dynamically allocated based on actual retransmission needs across the entire network, reducing total resource consumption while maintaining allocation simplicity through centralized management.
Solution Approach 2:
The patent transforms static resource allocation into dynamic allocation. Resources are no longer fixed per link but are flexibly assigned based on real-time channel conditions and retransmission requirements. This dynamic approach allows the system to adapt resource distribution to actual needs, improving efficiency while reducing waste.
2Device complexity
If static resource allocation is used for each link, then resource management is straightforward, but communication reliability and latency performance deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the controller monitors transmission success rates and channel conditions across all links. Based on this feedback, the controller dynamically adjusts resource allocation to prioritize links experiencing failures or poor conditions, thereby improving communication reliability while managing complexity through automated decision-making.
Solution Approach 2:
The system enables self-service through automated resource allocation algorithms that respond to transmission needs without manual intervention. The controller automatically detects retransmission requirements and allocates resources accordingly, improving reliability while keeping management complexity handled by the system itself rather than requiring complex external coordination.
3Productivity
If dynamic resource allocation is implemented, then resource efficiency improves, but system complexity increases
Solution Approach 1:
The patent creates a universal resource pool that serves multiple links and transmission types. This multi-functional resource pool is managed by a single controller that handles allocation for different links, transmission modes, and retransmission scenarios uniformly. This universality improves retransmission efficiency across the board while managing complexity through a single standardized allocation mechanism rather than multiple specialized systems.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine an estimated total amount of resources for one or more retransmissions of communications among the base station, a controller, and a device, the one or more retransmissions associated with one or more transmissions between at least two of the base station, the controller, or the device; and transmit, to at least one of the controller or the device, an indication of an allocation of resources based at least in part on the estimated total amount of resources for the one or more retransmissions. Numerous other aspects are provided.
