UE Paging Indication Detection for Power Saving in 5G Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently implementing relay transmission to enhance communication rate and quality, particularly in 5G communication systems where higher frequency bands and increased data rates are required.
Innovation Solution
A method for detecting indication information is introduced, which involves determining the carrier/narrowband position and time-domain position where the indication information is located. This information indicates whether a user equipment (UE) should monitor a paging message or a downlink control channel on associated paging occasions (POs). The detection unit then detects this information to determine the necessary monitoring actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment continuously monitors downlink control channel and paging messages to ensure communication reliability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements discontinuous reception (DRX) cycles where user equipment alternates between active monitoring periods and sleep periods. During active periods, the UE monitors downlink control channels and paging messages; during sleep periods, monitoring is suspended to save power. This periodic action resolves the contradiction by maintaining communication reliability during active periods while reducing power consumption during sleep periods.
Solution Approach 2:
The system enables user equipment to autonomously determine when to wake up and monitor based on pre-configured DRX parameters and received indication information. The UE self-manages its monitoring schedule without continuous network control, activating only when necessary to receive paging messages or downlink data, thus balancing reliability and power consumption independently.
2Loss of time
If user equipment monitors paging occasions frequently to ensure timely message reception, then message reception timeliness is improved, but power consumption increases
Solution Approach 1:
The patent uses configured DRX cycles with specific wake-up timings to periodically monitor paging occasions. The UE wakes up at predetermined intervals to check for paging messages, ensuring timely reception when messages are present while avoiding continuous monitoring that would waste power. The periodic structure balances timeliness and power consumption by concentrating monitoring efforts at critical moments.
Solution Approach 2:
The network provides indication information in advance that helps user equipment determine whether paging messages will be transmitted in upcoming occasions. The UE uses this preliminary information to intelligently activate or skip monitoring, avoiding unnecessary wake-ups and power consumption while ensuring timely reception when messages are actually present.
3Reliability
If user equipment monitors all downlink control channels to ensure no data is missed, then data reception completeness is improved, but device complexity increases
Solution Approach 1:
The patent extracts and processes only critical indication information from downlink control channels to determine whether full paging message monitoring is necessary. Instead of monitoring all channels continuously, the UE first checks for condensed indication signals that convey essential information about upcoming paging occasions, thereby reducing monitoring complexity while maintaining data reception completeness.
Solution Approach 2:
The monitoring process is segmented into multiple stages: first receiving and processing indication information, then conditionally proceeding to full paging message monitoring only when necessary. This segmentation divides the complex continuous monitoring task into manageable discrete steps, reducing overall device complexity while ensuring no data is missed when required.
