Cross-Link Beam Information for Independent Multi-TRP Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effectively managing and coordinating multiple independent links between user equipment (UE) and transmit-receive points (TRPs), particularly in terms of beam information transmission and resource allocation across these links.
Innovation Solution
The system enables communication through multiple independent links by using a processor and memory to manage data and beam information transmission across different wireless communication links, including channel sensing, control information sharing, and dynamic power control, allowing for independent processing and allocation of resources across each link.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If beam information for multiple links is transmitted through a single shared control channel, then resource allocation is simplified, but link independence and reliability are compromised
Solution Approach 1:
The patent divides the control channel resources into separate independent control channels for each wireless link. Each control channel independently carries control information including beam information for its corresponding link, ensuring that link failures or interference do not propagate across multiple links. This segmentation maintains link independence while managing control channel resources systematically.
2Reliability
If independent control channels are used for each link, then link reliability and independence are improved, but system complexity and resource overhead increase
Solution Approach 1:
The patent implements a universal control channel framework where each independent control channel follows the same structure and protocol for transmitting control information including beam information. This standardized approach allows the system to manage multiple independent links using consistent procedures, reducing the operational complexity despite having separate control channels for each link.
3Productivity
If resources are shared across multiple links, then resource utilization efficiency is improved, but the ability to independently manage each link is reduced
Solution Approach 1:
The patent segments resource allocation into link-specific resource pools, where each wireless link has its own dedicated resources for data and control information transmission. This segmentation enables independent management and optimization of each link while maintaining overall system productivity through coordinated resource allocation across multiple links.
4Device complexity
If a single control channel is used for all links, then system complexity is reduced, but beam information transmission reliability for individual links deteriorates
Solution Approach 1:
The patent segments the control information transmission into separate independent control channels, where each control channel is dedicated to transmitting control information including beam information for a specific wireless link. This ensures that beam information for each link is transmitted reliably without being affected by interference or failures on other links, while maintaining manageable system complexity through structured organization.

AI summary
Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.
