Base Station Antenna Receiving Mode Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna receiving modes in wireless communication systems, such as WCDMA and CDMA2000, face challenges in balancing uplink receiving performance with resource efficiency, as configuring a 4-antenna mode requires more hardware and baseband resources, while a 2-antenna mode may not satisfy user performance requirements.
Innovation Solution
A method for dynamically configuring antenna receiving modes based on user-specific resource allocation information, allowing for real-time monitoring and adjustment of antenna receiving modes to optimize resource usage, ensuring each user's uplink performance is met without unnecessary resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 4-antenna receiving mode is configured, then uplink receiving performance is improved, but hardware investment and baseband processing resources increase
Solution Approach 1:
The patent implements dynamic antenna receiving mode configuration where the base station controller monitors baseband processing resource availability and channel element consumption in real-time, then dynamically adjusts the antenna receiving mode (2-antenna or 4-antenna) for each user based on current resource conditions and user requirements, rather than using a fixed configuration
Solution Approach 2:
The patent applies different antenna receiving modes to different users based on their specific channel conditions, service requirements, and resource allocation needs. Each user can be configured with 2-antenna or 4-antenna mode locally according to their individual requirements, rather than applying a uniform configuration to all users
2Device complexity
If a 2-antenna receiving mode is configured, then hardware and baseband processing resources are saved, but uplink receiving performance of users may not be satisfied
Solution Approach 1:
The base station controller continuously monitors baseband processing resource availability and channel element consumption, using this feedback information to dynamically adjust antenna receiving mode configurations. When resources are abundant, 4-antenna mode can be applied; when resources are constrained, 2-antenna mode is used, ensuring performance requirements are met while optimizing resource utilization
Solution Approach 2:
The system changes the antenna receiving mode parameter (2-antenna or 4-antenna) based on dynamic assessment of resource conditions and user requirements. This parameter adjustment allows the system to adapt between resource-saving and performance-optimizing configurations

AI summary
Embodiments of the present invention disclose an antenna receiving mode configuration processing method, a base station controller, and a base station. When a user applies to a base station for establishing or adding radio links, an antenna receiving mode of the user is determined according to resource allocation information of the user. User admission processing is performed according to a channel element consumption rule that corresponds to the antenna receiving mode of the user. The base station controller includes a mode determining module and an admission processing module. The base station includes a configuring module, a monitoring module, and an adjusting module.
