Dynamic Resource Allocation for 4G-5G Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks coexisting with 4G networks, terminals with different Radio Access Technologies (RATs) interfere with each other when sharing resources, leading to inefficient resource utilization due to differing resource requirements and quantities.
Innovation Solution
A base station determines and allocates specific resources from a shared target resource to each RAT, using network parameters to optimize resource allocation and prevent waste, by sending indication information to the terminals to manage their resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 4G terminal is allowed to use all shared resources and a 5G terminal uses dedicated resources, then interference between different RAT terminals is resolved, but resource utilization efficiency deteriorates when 4G terminal quantity is small
Solution Approach 1:
The patent segments the shared resources into two parts: dedicated resources for 5G terminals and shared resources for 4G terminals. The base station dynamically determines the quantity of shared resources based on the quantity of 4G terminals, allowing flexible allocation that prevents waste when 4G terminal quantity is small while ensuring sufficient resources when 4G terminal quantity is large.
2Loss of energy
If shared resources are allocated dynamically based on 4G terminal quantity, then resource utilization efficiency improves, but system complexity increases
Solution Approach 1:
The patent changes the parameter of resource quantity allocation dynamically based on the quantity of 4G terminals. The base station determines the quantity of shared resources according to the current 4G terminal count, adjusting the allocation parameter to match actual network conditions, thereby improving efficiency without requiring complex multi-dimensional optimization algorithms.

AI summary
A wireless communication method, a base station and a terminal are disclosed. In an embodiment a method includes determining, by a base station, a first resource and a second resource from a target resource, wherein the target resource is a resource shared by at least one terminal in a first Radio Access Technology (RAT) and at least one terminal in a second RAT, the first resource being a resource used by the terminal in the first RAT, and the second resource being a resource used by the terminal in the second RAT, sending, by the base station, first indication information to the terminal in the first RAT, wherein the first indication information is used to indicate the first resource to be used by the terminal in the first RAT and sending, by the base station, second indication information to the terminal in the second RAT, wherein the second indication information is used to indicate the second resource to be used by the terminal in the second RAT.
