Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in efficiently managing the transmission of burst signals and discovery reference signals in shared frequency bands, particularly in unlicensed bands, where collisions and resource allocation issues hinder seamless communication.
Innovation Solution
A base station controller is designed to prioritize and coordinate the transmission of burst signals and discovery reference signals, using a shared antenna port and optimizing resource allocation within the transmission duration to ensure efficient communication in both licensed and unlicensed bands, while omitting unnecessary determination processes and utilizing synchronization signals for demodulation.

Engineering Contradiction Analysis
1Productivity
If the base station transmits both burst signal and discovery reference signal in the same transmission duration, then resource utilization is improved, but signal interference and transmission reliability deteriorate
Solution Approach 1:
The transmission duration is segmented into multiple slots, with each slot dedicated to either burst signal or discovery reference signal transmission. This time-domain segmentation prevents signal collisions while maintaining high resource utilization, as the base station can dynamically allocate different slots to different signal types based on traffic conditions and measurement requirements.
Solution Approach 2:
The base station dynamically adjusts the transmission timing and resource allocation of burst signals and discovery reference signals based on real-time channel conditions, traffic load, and measurement requirements. This dynamic scheduling allows the system to optimize resource utilization while ensuring transmission reliability by avoiding conflicts when needed and maximizing throughput when conditions permit.
2Measurement precision
If the base station performs determination process for each signal transmission, then transmission accuracy is improved, but processing time and complexity increase
Solution Approach 1:
The base station performs channel assessment and resource selection in advance before actual signal transmission. By conducting determination processes preliminarily and caching the results, the system reduces real-time processing time while maintaining transmission accuracy. The preliminary determination includes selecting appropriate transmission slots, power levels, and resource blocks based on predicted channel conditions.
Solution Approach 2:
The base station merges multiple determination processes into a single unified scheduling decision. Instead of separately determining transmission parameters for burst signals and discovery reference signals, the system performs a combined resource allocation that simultaneously optimizes both signal types, reducing overall processing time while maintaining the accuracy needed for reliable transmission.

AI summary
A base station according to an embodiment includes a controller configured to perform a process of transmitting, in a specific frequency band shared by a plurality of operators and/or a plurality of communication systems, a burst signal including data or a control signal and a discovery reference signal including a reference signal and/or a synchronization signal. If there is a transmission duration of the discovery signal within a transmission duration of the burst signal after starting the transmission of the burst signal, the controller performs a process of transmitting the discovery reference signal even within the transmission duration of the burst signal.
