Paging Early Indication Conflict Handling for Low-Power UE Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power consumption in user equipment during periodic monitoring for paging messages is high due to conflicts between paging early indications (PEI) and other channels or information, leading to abnormalities in sending and receiving PEI.
Innovation Solution
A method and apparatus for handling conflicts between PEI and other channels or information by determining processing manners based on the type of conflict, including discarding, deferring, or punching the PEI, depending on whether the user equipment can predict the resource usage of the conflicting information or channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the base station sends PEI to indicate paging information, then power consumption is reduced, but conflicts with other information or channels cause abnormalities
Solution Approach 1:
The patent changes the transmission parameters of PEI by selecting different time-frequency resources based on conflict detection. When conflicts are detected with other information or channels, the system adjusts the PEI transmission parameters (time slot, frequency resource) to avoid collisions, thereby maintaining transmission reliability while preserving power savings.
Solution Approach 2:
The patent implements dynamic resource allocation for PEI transmission. The base station dynamically selects transmission resources based on real-time channel conditions and conflict detection with other information. This dynamic adjustment ensures reliable PEI delivery while optimizing power consumption by avoiding unnecessary transmissions.
2Productivity
If the base station flexibly manages PEI processing (discarding, deferring, or punching), then resource utilization is optimized, but system complexity increases
Solution Approach 1:
The patent employs parameter-based decision making for PEI processing. Different processing manners (discarding, deferring, punching) are selected based on predefined parameters such as conflict type, channel conditions, and priority levels. This systematic approach optimizes resource utilization while keeping processing complexity manageable through rule-based decisions.
Solution Approach 2:
The patent applies different processing strategies to different PEI instances based on local conditions. Instead of a uniform processing approach, the system tailors the processing manner (discarding, deferring, or punching) to specific conflict scenarios and resource availability, thereby optimizing overall resource utilization without requiring complex global coordination.

AI summary
A method for sending a paging early indication (PEI) is performed by a base station and includes: in response to a conflict between the PEI to be sent and other information or other channel, determining a processing manner for the PEI based on the other information or the other channel. A method for receiving a PEI is performed by a user equipment and includes: in response to a conflict between the PEI to be received and other information or other channel, determining a receiving manner for the PEI based on the other information or the other channel.
