Master Base Station Timing Window for Beam Pair Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently establishing beam pair links, particularly in dual connectivity operations, where determining a timing window for user equipment (UE) to monitor a downlink channel is not optimized, leading to potential resource inefficiencies and increased time for beam alignment.
Innovation Solution
A method where a master base station determines a timing window for the UE to monitor a downlink channel associated with a secondary base station, allowing the UE to establish a beam pair link based on this monitoring, which can be part of a dual connectivity or carrier aggregation procedure, using messages to coordinate beam parameter measurement and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE monitors the downlink channel continuously to establish a beam pair link, then the reliability of beam alignment is improved, but the energy consumption and resource efficiency deteriorate
Solution Approach 1:
The master base station determines and provides timing window information to the UE before the UE needs to monitor the downlink channel. This preliminary action allows the UE to prepare and monitor only during specific predetermined time windows, rather than continuously, thus maintaining reliable beam alignment while reducing energy consumption and resource usage
2Measurement precision
If the UE monitors the downlink channel for an extended period to ensure beam pair link establishment, then the beam alignment accuracy is improved, but the time required for establishment increases
Solution Approach 1:
The master base station determines optimal timing windows in advance and provides this information to the UE before monitoring begins. This allows the UE to concentrate monitoring efforts during precise predetermined windows, achieving accurate beam alignment without requiring extended monitoring periods, thus resolving the contradiction between alignment accuracy and establishment time
3Reliability
If the UE monitors the downlink channel frequently to establish beam pair links in dual connectivity, then the connection reliability is improved, but the resource efficiency deteriorates
Solution Approach 1:
The master base station determines timing windows for monitoring downlink channels associated with secondary base stations in advance and provides this information to the UE. This allows the UE to monitor only during specific predetermined time windows rather than continuously or frequently, maintaining reliable dual connectivity while significantly improving resource efficiency by reducing unnecessary monitoring activities

AI summary
Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.
