Base Station Reference Signal Configuration for UE Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in balancing the unique characteristics and communication needs of various user equipment (UE) types, such as enhanced mobile broadband (eMBB) and reduced capability (Redcap) UEs, which differ in bandwidth and processing capabilities, leading to inefficient reference signal configuration and increased power consumption.
Innovation Solution
The method involves configuring reference signal configuration information based on the type of UE, including tracking reference signals (TRS) and channel state information-reference signals (CSI-RS), to optimize time-frequency domain synchronization and wireless resource management, allowing UEs to share or have separate configurations tailored to their specific needs, thereby reducing power consumption and improving resource utilization.

Engineering Contradiction Analysis
1Ease of operation
If a unified reference signal configuration is used for all UE types, then device complexity is reduced and ease of operation is improved, but communication efficiency deteriorates and power consumption increases for capability-limited UEs
Solution Approach 1:
The patent segments the reference signal configuration into UE-type-specific configurations. Different UE types (e.g., capability-limited UEs versus advanced UEs) receive tailored reference signal configurations that match their processing capabilities and communication needs, thereby improving communication efficiency without compromising operational simplicity through automated type-based assignment.
Solution Approach 2:
The patent applies local quality by customizing reference signal parameters (such as bandwidth, density, and resource allocation) according to the specific characteristics of each UE type. Capability-limited UEs receive optimized configurations that reduce processing burden and power consumption, while advanced UEs receive configurations that maximize their communication performance.
2Use of energy by moving object
If reference signal configuration is optimized for capability-limited UEs, then power consumption is reduced and communication efficiency is improved, but device complexity increases and adaptability to different UE types deteriorates
Solution Approach 1:
The patent establishes a universal reference signal configuration framework that serves multiple UE types through type-specific parameter sets. The base station maintains a library of configurations adapted to different UE capabilities and automatically selects the appropriate configuration based on UE type identification, thereby achieving both power optimization for capability-limited UEs and broad adaptability across diverse UE types without increasing perceived system complexity.
3Productivity
If UE-type-specific reference signal configurations are implemented, then communication efficiency and power consumption are optimized, but measurement precision and synchronization accuracy may deteriorate due to configuration differences
Solution Approach 1:
The patent carefully manages parameter changes by adjusting reference signal configurations based on UE type while maintaining critical parameters that affect synchronization accuracy and measurement precision. Essential parameters such as time synchronization offsets and frequency alignment references are kept consistent across UE types, while non-critical parameters like resource allocation density and bandwidth utilization are optimized for specific UE capabilities, thereby achieving both efficiency improvement and measurement accuracy preservation.
