Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately decoding information carrying signals due to mismatches between user equipment (UE) specific muting configurations and transmission point configurations, particularly in CoMP transmission scenarios, leading to suboptimal link adaptation and spectral efficiency.
Innovation Solution
Implementing dynamic muting configurations that match the selected transmission configuration, allowing the UE to correctly decode signals by adjusting muting patterns based on transmission point associations, and configuring multiple interference measurement resources to account for intra-cluster interference hypotheses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE specific muting configurations are used in CoMP transmission scenarios, then interference measurement capabilities are improved, but mismatches between UE specific muting configurations and transmission point configurations occur leading to decoding failures
Solution Approach 1:
The patent applies dynamics by making the muting configuration dynamic rather than static. The network node determines a plurality of muting configurations corresponding to different transmission configurations, and dynamically selects and indicates the appropriate muting configuration to the UE based on the actual transmission configuration being used. This dynamic adaptation ensures that the muting configuration always matches the transmission configuration, resolving the mismatch problem while maintaining accurate interference measurements.
Solution Approach 2:
The patent changes the parameter of muting configuration from a fixed UE-specific setting to a multi-configurable parameter set that can be adjusted based on transmission conditions. By determining multiple muting configurations corresponding to different transmission configurations and selecting the appropriate one dynamically, the system adapts the muting parameters to match the actual transmission scenario, ensuring both measurement accuracy and decoding reliability.
2Productivity
If multiple transmission configurations are available for CoMP transmission, then system performance and coverage are improved, but complexity in managing and coordinating muting configurations increases
Solution Approach 1:
The patent applies universality by creating a unified muting configuration management mechanism that serves multiple transmission configurations. Instead of managing separate muting configurations for each transmission point independently, the network node determines a set of muting configurations that can be universally applied across different transmission scenarios. The UE is provided with this unified configuration set and the appropriate one is indicated based on the active transmission configuration, simplifying management while supporting multiple CoMP transmission modes.
Solution Approach 2:
The patent applies preliminary action by pre-determining and providing the UE with a plurality of muting configurations corresponding to different transmission configurations before actual transmission occurs. The network node prepares the configuration set in advance and indicates which configuration to use based on the selected transmission configuration. This preliminary preparation eliminates the need for complex real-time configuration management during transmission, reducing operational complexity.
3Reliability
If dynamic configuration messages are used to indicate muting configurations, then link adaptation accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent applies partial action by providing the UE with a plurality of muting configurations corresponding to different transmission configurations, but only indicating the specific configuration that is currently needed. Instead of transmitting complete configuration details for all possible scenarios, the system sends a compact indication pointing to the relevant configuration in the pre-provided set. This reduces signaling overhead while maintaining the ability to provide accurate, dynamic muting configurations for link adaptation.
