Coherence-Based Pre-Decoding Pruning for Control Channel Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, UEs face inefficiencies in processing control channel messages due to interference and the need to decode all messages, even if none are intended for them, leading to increased power consumption and processing time.
Innovation Solution
The method involves determining channel coherence metrics to identify which channel resources contain data intended for the UE, allowing it to prune out unnecessary processing and decoding by determining channel coherence metrics for each channel resource and selecting only those likely to contain intended data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs decode all control channel messages, then message completeness is ensured, but power consumption and processing time increase
Solution Approach 1:
The patent applies preliminary action by calculating channel coherence metrics before full decoding to predict which control channel messages contain data for the UE. This allows the UE to perform preliminary assessment of channel coherence for each control channel message before committing to full decoding, thereby avoiding unnecessary processing of messages not intended for the UE while ensuring reliable reception of intended messages.

3Reliability
If UEs process all control channel messages, then data reliability is ensured, but processing efficiency decreases
Solution Approach 1:
The patent applies preliminary action by calculating channel coherence metrics before full decoding to predict which control channel messages contain data for the UE. This allows the UE to perform preliminary assessment of channel coherence for each control channel message before committing to full decoding, thereby avoiding unnecessary processing of messages not intended for the UE while ensuring reliable reception of intended messages.
Solution Approach 2:
The patent applies local quality by treating each control channel message differently based on its channel coherence metrics. Instead of uniformly processing all messages, the UE calculates coherence metrics for each message and selectively decodes only those with sufficient coherence, optimizing processing efficiency while maintaining reliability for intended messages.

AI summary
Coherence based pre-decoding pruning for control channels in wireless communication systems is discussed. Data is received on at least one channel resource of a plurality of channel resources. In addition, the determining of a plurality of channel coherence metrics is discussed, where a channel coherence metric for a channel resource indicates coherence information between channels on which the plurality of carriers associated with the channel resource operate. Additionally, the determining of one or more channel resources to search for data to be decoded based, at least in part, on the plurality of channel coherence metrics is also discussed. Other aspects, embodiments, and features are also claimed and described.
