DRX Paging Monitoring Across Multi-Beam Time Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a multi-beam environment, networks face challenges in identifying which beam index a user equipment has selected, leading to inefficient transmission of paging messages, as existing technologies lack guidance on beam selection for user equipment in discontinuous reception modes.
Innovation Solution
An electronic device determines a time slot for monitoring based on signal strength measured in a previous period, optimizing power and resource usage by selectively waking up for paging message reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network transmits paging messages for each beam index in every time slot, then the paging message delivery reliability is improved, but the device power consumption increases due to frequent wake-ups for monitoring
Solution Approach 1:
The device performs signal strength measurement in advance during previous periods and stores this information. Based on this preliminary measurement, the device can determine which time slots to monitor in advance, avoiding the need to monitor all time slots while ensuring paging messages are not missed. This resolves the contradiction by preparing information beforehand that enables selective monitoring.
Solution Approach 2:
Instead of monitoring all time slots (excessive action), the device monitors only a subset of time slots determined by signal strength measurements (partial action). The device measures signal strength for each beam index and selectively monitors only those time slots corresponding to beams with sufficient signal strength, reducing power consumption while maintaining reliable paging message reception.
2Reliability
If the device monitors all time slots for paging messages, then the paging message reception reliability is improved, but the resource consumption increases
Solution Approach 1:
The device performs partial monitoring by selecting only certain time slots based on signal strength measurements. Instead of monitoring all time slots which would consume excessive resources, the device monitors only those time slots where paging messages are likely to be received successfully, based on pre-measured signal strength for each beam index.
Solution Approach 2:
The device performs signal strength measurements in advance during previous periods and uses this information to determine monitoring strategy. This preliminary action enables the device to optimize resource usage by avoiding monitoring of time slots where signal strength is insufficient, while ensuring reliable reception in time slots with adequate signal strength.
3Reliability
If the device wakes up frequently to monitor paging messages in all time slots, then the paging message detection capability is improved, but the battery consumption increases
Solution Approach 1:
The device performs partial monitoring by waking up only for specific time slots determined by signal strength measurements. Instead of waking up for all time slots (excessive action), the device selectively wakes up only when necessary based on pre-measured signal conditions, reducing battery consumption while maintaining effective paging message detection capability.
Solution Approach 2:
The device performs signal strength measurements in advance and stores this information for later use. This preliminary measurement enables the device to make informed decisions about when to wake up for monitoring, avoiding unnecessary wake-ups in time slots with poor signal conditions and thus reducing battery consumption while maintaining detection capability.
