UE PDCCH Monitoring Time Offset Configuration for uRLLC and eMBB Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, User Equipment (UE) faces challenges in simultaneously processing high priority ultra-reliable low latency communication (uRLLC) and low priority enhanced mobile broadband (eMBB) channels due to prioritization leading to inability to meet eMBB processing timelines.
Innovation Solution
The UE is reconfigured with time offsets based on minimum processing capabilities to increase processing time for eMBB channels, allowing simultaneous processing of both uRLLC and eMBB channels without impacting latency requirements, by adding additional time for PDCCH, PDSCH, or PUSCH processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE prioritizes processing uRLLC BD/CCE candidates over eMBB BD/CCE candidates in a single pipeline, then uRLLC processing reliability is improved, but eMBB processing timeline is not met
Solution Approach 1:
The patent divides the processing pipeline into two separate pipelines: a first processing pipeline dedicated to uRLLC BD/CCE candidates and a second processing pipeline dedicated to eMBB BD/CCE candidates. This segmentation allows simultaneous processing of both high-priority uRLLC and low-priority eMBB channels without mutual interference, resolving the contradiction between uRLLC reliability and eMBB timeline compliance.
2Device complexity
If the UE uses a single processing pipeline for both uRLLC and eMBB channels, then device complexity is reduced, but the inability to meet eMBB processing timeline occurs
Solution Approach 1:
The patent introduces a segmented dual-pipeline architecture where processing functions are divided into specialized first and second processing pipelines. While this increases device complexity compared to a single pipeline, it enables simultaneous handling of uRLLC and eMBB channels, ensuring eMBB processing timeline requirements are met without compromising uRLLC latency constraints.
3Adaptability or versatility
If the UE processes all uRLLC BD/CCE candidates before eMBB BD/CCE candidates, then uRLLC priority requirements are satisfied, but eMBB processing is delayed
Solution Approach 1:
The patent creates separate processing pipelines that operate concurrently: the first processing pipeline handles uRLLC BD/CCE candidates with high priority scheduling, while the second processing pipeline handles eMBB BD/CCE candidates independently. This segmentation enables the system to maintain adaptability to priority requirements while eliminating sequential processing delays, as both pipelines execute simultaneously rather than one after the other.

AI summary
Methods and apparatuses are provided for receiving, from a user equipment (UE) configured to process a first priority channel using a first monitoring span based on the first priority channel during one or more time periods, at least one parameter indicating a minimum amount of time required by the UE to process the first priority channel using a second monitoring span based on the first priority channel and a second priority channel. The one or more time periods are based on minimum processing capabilities of the UE. Based on the at least one parameter, the UE is caused to be reconfigured with at least one time offset to increase at least one time period of the one or more time periods for processing the first priority channel.
