Dual-SIM Beam Management Threshold Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-SIM dual standby devices face issues with beam alignment due to alternating allocation of RF resources, leading to skipped beam management operations and potential beam failure recovery disruptions, especially in high mobility scenarios.
Innovation Solution
A method that allocates radio transceivers for alternative active periods between SIMs, allowing the SIM in connected mode to perform beam management operations and monitor paging messages, with mechanisms to determine a threshold for skipped operations and adjust resource allocation to maintain beam alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RF resources are allocated to both SIMs in alternating manner, then both SIMs can share the single RF resource, but the SIM in connected mode may skip beam management operations and lose beam alignment
Solution Approach 1:
The system monitors the number of skipped beam management operations and uses this feedback to dynamically adjust RF resource allocation. When the threshold is reached, the system switches to prioritizing the connected mode SIM, ensuring beam alignment is maintained through continuous feedback and adjustment
Solution Approach 2:
The RF resource allocation is made dynamic rather than static. The system can switch between different allocation modes (alternating vs. prioritized) based on the operational state and beam alignment status, allowing adaptive response to changing conditions
2Ease of operation
If RF resources are allocated to SIM in idle mode for paging monitoring, then paging messages can be monitored, but beam management operations of SIM in connected mode are skipped
Solution Approach 1:
The system automatically monitors skipped operations and self-adjusts the resource allocation without external intervention. When beam management operations are skipped, the system autonomously switches to prioritizing that SIM, ensuring self-correction of the allocation strategy
3Reliability
If beam management operations are performed frequently, then beam alignment is maintained, but RF resources are consumed and may conflict with paging monitoring
Solution Approach 1:
The system changes the allocation parameter (time slot distribution) based on the threshold condition. When skipped operations are below threshold, alternating allocation is used; when threshold is reached, prioritized allocation is applied, dynamically adjusting parameters to balance beam management and paging monitoring

AI summary
An apparatus may include a processor and computer program code, and may be configured to cause the apparatus to allocate a radio transceiver for a communication of a first SIM and a second SIM for alternative active periods, wherein the first SIM is configured to at least monitor paging messages during its active periods and the second SIM is configured to perform beam management operations during its active periods; monitor a number of scheduled beam management operations of the second SIM skipped during the active periods of the radio transceiver allocated for the first SIM; determine, based on at least data from the performed beam management operations, a threshold value for the skipped beam management operations; and adjust, in response to the number of the skipped beam management operations reaching the threshold value, allocation of the active periods of the radio transceiver between the first SIM and the second SIM.
