Wireless Station Scheduling Logic for Measurement Gap and On-Duration Interval Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile devices using discontinuous reception (DRX) mode, overlapping measurement gaps and on-duration intervals can cause communication difficulties and throughput loss when transitioning between base stations.
Innovation Solution
A controller is configured with scheduling logic to schedule measurement gaps and on-duration intervals to avoid overlapping, ensuring seamless communication by determining optimal timing parameters such as measurement gap offset and on-duration offset based on connection modes and paging signal parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile device performs measurements during a measurement gap, then the mobile device can obtain information about neighboring base stations for handover, but the mobile device cannot receive communications from the current base station causing throughput loss
Solution Approach 1:
The system performs measurements during the on-duration interval before the measurement gap begins, allowing the mobile device to obtain neighboring base station information without interrupting communication with the current base station. This preliminary action eliminates the need to pause communication during the measurement gap.
Solution Approach 2:
The system combines the measurement function with the on-duration interval by scheduling measurements to occur during this period when the mobile device is already active for communication. This merging allows both communication and measurement functions to be performed simultaneously during the same time interval.
2Use of energy by moving object
If the mobile device uses DRX mode to conserve power, then power consumption is reduced, but communication continuity may be affected when measurement gaps overlap with on-duration intervals
Solution Approach 1:
The system dynamically adjusts the scheduling of measurement gaps relative to on-duration intervals based on the connection mode and paging signal parameters. By making the scheduling flexible and adaptive rather than fixed, the system ensures that measurements occur during active communication periods without disrupting the power-saving DRX cycle structure.
Solution Approach 2:
The system uses feedback from the base station regarding connection mode and paging signal parameters to adjust measurement gap scheduling. This feedback mechanism allows the mobile device to align measurement activities with communication requirements while maintaining optimal power saving behavior.

AI summary
Systems, methods, and other embodiments associated with scheduling of measurement gaps and on-duration intervals for a wireless station are described. According to one embodiment, a controller for controlling a station that wirelessly communicates with a base station is disclosed. The station is within a wireless range of the base station and one or more neighboring stations. The controller includes a scheduling logic configured to control the station, while the station is in an idle mode, to receive control information from the base station by scheduling a period of time for an on-duration interval. The scheduling logic is configured to control the station to listen to the one or more neighboring stations by scheduling a period of time for a measurement gap. The measurement gap is scheduled to avoid overlapping with the on-duration interval.
