Clustered Resource Allocation Reducing Overhead in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bitmap notification method in wireless communication systems leads to high overhead and low reliability in resource allocation, particularly when prioritizing services with high priority, as it requires significant indication overhead and can decrease the reliability of performance.
Innovation Solution
A resource allocation method where a first communication node determines and notifies a second communication node about resources to be allocated, divided into K clusters of continuous resources, allowing the second node to avoid specific resources when sending data, thereby reducing overhead and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bitmap notification manner is used to notify resources, then resource allocation can be achieved, but indication overhead becomes large causing waste of resources
Solution Approach 1:
The patent divides the notification mechanism into two segments: a first notification message indicating resource allocation, and a second notification message providing detailed resource information. This segmentation reduces the overhead in the first message while ensuring complete information is transmitted through the second message, resolving the contradiction between overhead reduction and information completeness.
Solution Approach 2:
The patent performs preliminary notification of resource allocation through the first notification message before providing detailed resource information through the second notification message. This preliminary action allows the receiving device to prepare for resource reception/processing in advance, reducing the need for large overhead in a single message while maintaining reliability.
2Productivity
If bitmap notification manner is used to notify resources, then resource allocation can be achieved, but reliability of indication information decreases
Solution Approach 1:
The patent segments the indication information into multiple notification messages, where the first message provides resource allocation indication and the second message provides detailed resource information. This segmentation improves reliability by ensuring that critical information is transmitted through multiple channels, preventing information loss that would occur with a single bitmap message.
Solution Approach 2:
The patent introduces an intermediary mechanism where the first notification message serves as a preliminary indicator and the second notification message serves as a detailed descriptor. This intermediary approach ensures that resource allocation information is transmitted reliably through multiple stages, preventing the reliability degradation that occurs with direct bitmap notification.

AI summary
Provided are a resource allocation method and device, a storage medium and an electronic device. The method includes the following operations. A first communication node determines resources needing to be allocated to a second communication node, where the resources include K clusters, each cluster includes one or more continuous resources, a maximum value of K is Kmax, Kmax is a predefined value or a value agreed in advance between the first communication node and the second communication node, and Kmax is a positive integer greater than 1. The first communication node notifies the second communication node of the resources, wherein the resources are resources needing to be avoided when the second communication node receives and/or sends a channel or a signal, or resources from which the second communication node, when needing to send data, selects one or more clusters of resources to send the data.
