Paging Decoding Reduction via Downlink Control Information Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE and 5G networks, user equipment (UEs) often receive unnecessary paging messages due to the lack of clear indication in downlink control information, leading to increased power consumption and resource usage, especially for reduced capability UEs, which can significantly impact battery life.
Innovation Solution
Incorporating downlink control information that explicitly indicates whether a UE group is paged, allowing UEs to determine whether to decode paging messages based on this information, thereby reducing unnecessary decoding and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UEs decode all paging messages without clear indication, then paging reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by including group paging indication information in the downlink control information before the paging message is transmitted. This allows UEs to determine in advance whether their group is being paged, enabling them to skip decoding of the paging message entirely when not needed, thus reducing power consumption while maintaining reliable paging delivery for targeted groups
2Reliability
If UEs decode all paging messages, then paging completeness is improved, but computing resource usage increases
Solution Approach 1:
The patent extracts the group paging indication information from the downlink control information and uses it to filter out unnecessary paging messages before UE decoding. This extraction mechanism allows UEs to take out only the relevant paging messages for their group, reducing computing resource usage while ensuring complete paging coverage for all targeted UEs
3Use of energy by moving object
If downlink control information includes group paging indication, then power efficiency is improved, but control information complexity increases
Solution Approach 1:
The patent applies segmentation by dividing UEs into different groups and providing group-specific paging indication information in the downlink control information. This segmentation approach allows the system to efficiently indicate paging status for specific groups without requiring complex individual indications for each UE, thus improving power efficiency while keeping control information structure manageable through organized group-based segmentation

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that schedules a paging message, wherein the downlink control information indicates whether a UE group associated with the UE is paged in the paging message. The UE may determine whether to decode the paging message based at least in part on the downlink control information that indicates whether the UE group associated with the UE is paged in the paging message. Numerous other aspects are provided.
