Multi-mode Base Station Slot Flexibility via Exchange Bus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed assignment of slots in multi-mode base stations makes it difficult to accurately predict the proportions of various modes, leading to insufficient capacity expansion for some modes while leaving others unused.
Innovation Solution
A multi-mode base station architecture that includes at least two base-band single-boards and an exchange bus, allowing for flexible connection of base-band single-boards to RF units, enabling mixed insertion of different modes and sharing of clock synchronization signals through a common module, which reduces the need for separate components and enhances flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed slots are assigned to different modes in advance, then the base station can operate with stable configuration, but the adaptability to future capacity expansion needs deteriorates
Solution Approach 1:
The patent implements dynamic slot mode assignment where the base station can flexibly configure slot modes based on real-time traffic demands and capacity expansion needs. The network controller dynamically adjusts which slots operate in which modes (WCDMA, GSM, etc.), allowing the system to transition from static to dynamic configuration, thereby resolving the contradiction between configuration stability and capacity expansion adaptability.
Solution Approach 2:
The patent creates a universal slot structure that can serve multiple communication modes. Each slot is designed to be multi-functional, capable of operating in different modes (WCDMA, GSM, etc.) depending on configuration. This universal slot design allows the same physical resources to adapt to different service requirements, improving both stability and adaptability simultaneously.
2Reliability
If separate RF lines are configured for different modes, then each mode can have optimized transmission, but the device complexity increases
Solution Approach 1:
The patent merges the RF line resources into a shared pool that can be dynamically allocated to different modes. Instead of having dedicated RF lines for each mode, the system combines RF resources and uses dynamic configuration to assign them to different modes as needed. This reduces the total number of RF lines required while maintaining mode-specific transmission quality through software-controlled resource allocation.
Solution Approach 2:
The patent creates universal RF line interfaces that can handle multiple communication modes. The RF lines are designed with multi-functionality, capable of supporting different modes (WCDMA, GSM, etc.) through configurable parameters and software control. This universal interface approach maintains transmission quality for each mode while significantly reducing hardware complexity by eliminating the need for separate dedicated RF lines for each mode.

AI summary
A multi-mode base station and a method for sending signals thereof are provided. In the base station, each base-band single-board is connected to a corresponding radio frequency (RF) unit through an exchange bus, and the base-band single-boards of different modes are intermixed by using the compatibility of the exchange bus.
