Wireless Resource Allocation via Dynamic Interference Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication methods face significant interference in low frequency bands, leading to increased data transmission delays and unreliable services, as existing frequency hopping technologies can only average interference over time and have limited application scenarios.
Innovation Solution
A wireless communication resource allocation method that dynamically allocates a first resource pool and a candidate second resource pool to terminal devices, where the network device continuously monitors and replaces physical resources with lower quality parameters, ensuring that communication data is transmitted over resources with lower interference, thereby improving data transmission reliability and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency hopping technology is used to avoid interference, then communication can continue at non-interfered frequencies, but the application scenarios are restricted and interference averaging is limited to fixed frequency communications
Solution Approach 1:
The patent implements dynamic resource replacement where the network device periodically replaces physical resources in the first resource pool with resources from the second resource pool based on real-time quality parameter measurements. This dynamic adaptation allows the system to respond to changing interference conditions and expand application scenarios beyond fixed frequency hopping, thereby improving both reliability and versatility.
Solution Approach 2:
The patent changes the quality parameter threshold dynamically based on interference conditions. The network device measures quality parameters (such as signal-to-interference ratio) and adjusts resource allocation decisions accordingly. This parameter-based adaptation enables the system to handle diverse interference scenarios effectively, resolving the contradiction between reliability and adaptability.
2Reliability
If frequency hopping is used to average interference over time, then communication can proceed, but data transmission delay increases and service requirements cannot be ensured
Solution Approach 1:
The patent applies preliminary action by pre-allocating a second resource pool of candidate resources before interference occurs. The network device prepares alternative resources in advance and only replaces physical resources when quality parameters indicate poor conditions. This proactive approach avoids the delays associated with reactive frequency hopping, ensuring continuous communication with minimal interruption.
Solution Approach 2:
The network device continuously measures quality parameters of physical resources and uses this feedback to trigger resource replacement only when necessary. This feedback mechanism prevents unnecessary resource switching and maintains communication continuity, thereby reducing transmission delay while ensuring reliability only when interference conditions actually deteriorate.
3Quantity of substance
If low frequency bands are used for communication, then spectrum resources are available, but high interference occurs and communication data transmission delay increases
Solution Approach 1:
The patent segments the available spectrum resources into a first resource pool for active communication and a second resource pool for backup candidates. This segmentation allows the system to isolate and manage interference by maintaining separate pools, enabling selective replacement of interfered resources while preserving access to low-frequency spectrum benefits.
Solution Approach 2:
The second resource pool acts as an intermediary buffer between the interfered first resource pool and the available spectrum. When interference affects the first pool, the second pool serves as a mediator to provide alternative clean resources, thereby reducing the harmful effects of interference while maintaining spectrum utilization efficiency.

AI summary
This application provides a wireless communication resource allocation method. A network device allocates, to a terminal device, a first resource pool used to carry communication data and a second resource pool including a candidate resource of the first resource pool, the network device measures a quality parameter of at least one physical resource in the first resource pool and the second resource pool, and the network device sends first indication information to the terminal device when a quality parameter of a first physical resource in the first resource pool satisfies a preset condition #1. The first indication information is used to indicate that the first physical resource in the first resource pool is replaced with a second physical resource, and the second physical resource is a physical resource in the second resource pool.
