Base Station Service Multiplexing and Dynamic Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems face low resource utilization due to static resource allocation methods, where resources allocated to different types of services remain idle when only one type of service is transmitted, leading to inefficient use of resources.
Innovation Solution
A method and device for service multiplexing and transmission, where a base station dynamically allocates resources based on the number of services being transmitted, allowing multiple types of services to share the same resource band by determining specific resources for each service and sending service multiplexing indication information to user equipment (UE), enabling dynamic regulation of occupied resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static resource allocation is used to ensure reliable service transmission, then service reliability is improved, but resource utilization deteriorates due to idle resources when only one service type is transmitted
Solution Approach 1:
The patent implements dynamic resource allocation where the base station determines whether to transmit one or multiple service types on the target resource and dynamically adjusts the occupied resources accordingly. When only one service type is transmitted, the base station occupies the entire target resource to ensure reliability; when multiple service types are transmitted, the base station dynamically allocates specific resources to each service type, preventing resource idleness and improving utilization efficiency.
Solution Approach 2:
The patent makes the target resource multi-functional by enabling it to bear multiple types of services simultaneously. The base station configures a target resource that can dynamically serve different service types (e.g., eMBB, URLLC, mMTC) based on transmission needs, allowing the same resource to be universally used for different services rather than being dedicated to a single service type, thus improving resource utilization while maintaining service reliability.
2Loss of energy
If multiple services are transmitted on the same frequency band to improve resource utilization, then resource utilization is improved, but service transmission complexity increases due to dynamic resource allocation and multiplexing indication
Solution Approach 1:
The patent segments the target resource into multiple sub-resources that can be independently allocated to different service types. When multiple services are transmitted, the base station determines specific resources for each service type within the target resource, dividing the resource allocation into manageable segments. This segmentation approach simplifies the management of multi-service transmission by allowing independent control and allocation of resources to each service type, reducing the overall transmission complexity.
Solution Approach 2:
The patent introduces service multiplexing indication information as an intermediary mechanism to manage multi-service transmission. The base station sends this indication information to user equipment to specify which service type is being transmitted on the target resource. This intermediary signaling approach simplifies the complexity by providing a clear, standardized method for indicating service types and their corresponding resources, making the dynamic resource allocation process more manageable and less complex for both the base station and user equipment.
3Productivity
If dynamic resource allocation is implemented to prevent resource idleness, then resource utilization is improved, but system complexity increases due to dynamic service determination and resource assignment
Solution Approach 1:
The patent implements preliminary action by pre-configuring the target resource at the base station before actual service transmission. The base station预先 configures the target resource parameters and prepares the resource allocation framework in advance. When service transmission is needed, the base station simply determines whether to transmit one or multiple service types and allocates resources accordingly, rather than performing complex resource setup operations in real-time. This preliminary configuration approach reduces system complexity by separating the resource preparation phase from the dynamic allocation phase, allowing efficient resource utilization without excessive system complexity.

AI summary
A method for service multiplexing and transmission can be applied to a base station. In a case that one type of service is to be sent on a target resource, the base station sends the one type of service based on all resources of the target resource. In a case that multiple types of service are to be sent on the target resource, for each type of service in the multiple types of service, the base station determines a resource pre-allocated to bear the type of service in the target resource, sends the type of service based on the determined resource corresponding to the type of service, and sends service multiplexing indication information to a UE which receives the type of service.
