Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring and indicating beams for network-controlled repeaters (NCRs) due to limitations in handling downlink and uplink beams independently, leading to inefficiencies in power usage and interference management.
Innovation Solution
A method for independently configuring and indicating downlink and uplink candidate beams for network-controlled repeaters (NCRs) using beam set indices, allowing flexible and adaptive beam management based on preconfigured candidate beam indices and side control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional beam configuration methods are used for NCRs, then the system maintains simplicity in beam management, but the system cannot independently optimize downlink and uplink beams leading to power waste and interference issues
Solution Approach 1:
The patent segments the beam management process into separate downlink and uplink beam configurations. Each beam (downlink and uplink) is independently configured with its own candidate beam sets and beam set indices, allowing independent optimization without coupling the two directions. This segmentation enables the system to achieve adaptability while managing complexity through structured separation.
2Productivity
If multiple beams are used simultaneously for downlink and uplink, then the system achieves better coverage and capacity, but the power consumption and interference increase
Solution Approach 1:
The patent implements dynamic beam selection where the gNB configures multiple candidate beam sets with different beam set indices, and the NCR dynamically selects appropriate beams based on current channel conditions and traffic requirements. This dynamic approach allows the system to achieve high communication capacity when needed while reducing power consumption by activating only necessary beams, avoiding continuous operation of all beams.
3Measurement precision
If beam indication is performed frequently to adapt to channel changes, then the beam alignment accuracy improves, but the signaling overhead and latency increase
Solution Approach 1:
The patent employs preliminary beam configuration where the gNB pre-configures multiple candidate beam sets and their corresponding beam set indices before actual beam selection is needed. This preliminary action allows the NCR to quickly select from pre-prepared beam options during channel changes, achieving accurate beam alignment without the latency of real-time beam configuration and signaling overhead.
