Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing resource configurations for master cell group and secondary cell group links in integrated access and backhaul nodes, particularly in dual connectivity scenarios, where consistent resource allocation and minimal signaling complexity are required to ensure reliable and robust communication.
Innovation Solution
The apparatus and method determine resource types for master cell group and secondary cell group links based on received resource configurations and operation modes, using predefined combinations and dynamic adjustments to ensure consistent resource allocation and minimize signaling complexity, supporting time division, spatial division, and frequency division duplexing operations.

Engineering Contradiction Analysis
1Reliability
If resource configurations are received and processed for multiple cell group links, then communication reliability is improved, but signaling complexity increases
Solution Approach 1:
The patent segments the resource configuration processing into distinct operations for different cell group links (first cell group link and second cell group link). Each link receives its own resource configuration independently, allowing the system to manage multiple links without overwhelming complexity. The segmentation is evident in the separate reception and processing steps for each link's configuration.
Solution Approach 2:
The patent applies preliminary action by determining resource types before actual communication occurs. The system determines whether resources are available for downlink, uplink, or flexible operations in advance, based on the received configurations. This preliminary determination prevents conflicts and ensures reliable communication without requiring complex real-time signaling during data transmission.
2Stability of the object's composition
If resource types are determined based on multiple configurations and operation modes, then resource allocation consistency is improved, but processing complexity increases
Solution Approach 1:
The patent implements universality by creating a single resource type determination mechanism that handles multiple cell group links and operation modes (time division duplexing, spatial division duplexing, frequency division duplexing) through a unified approach. The same processing logic applies to different links and duplexing modes, ensuring consistent resource allocation without requiring separate complex processing for each scenario.
Solution Approach 2:
The patent uses parameter changes by determining resource types based on varying configurations and operation modes. The system adjusts resource allocation parameters (downlink, uplink, flexible, or not available) according to the specific combination of received configurations and selected operation mode, enabling consistent resource management across different operational scenarios through parameter-based adaptation.
