Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those using multiple-access technologies like LTE and NR, face challenges in efficiently managing communication periods for multi-SIM user equipment (UE) to avoid interference and ensure reliable data transmission across multiple access links.
Innovation Solution
A method where a multi-SIM UE identifies specific time durations to use a second access link, transmits this information to a base station, and tunes to that link during designated times, allowing for reduced interference and improved communication by allocating processing resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-SIM UE establishes multiple access links simultaneously, then communication versatility is improved, but interference and reliability deteriorate due to resource conflicts
Solution Approach 1:
The patent implements periodic action by configuring specific time durations during which the UE tunes to the second access link. These time durations are periodically scheduled, allowing the UE to alternate between first and second access links in a structured manner, thereby maintaining multiple access link capabilities while avoiding simultaneous resource conflicts that cause interference
Solution Approach 2:
The patent applies dynamics by making the access link configuration adaptive and time-varying. The UE dynamically switches between different access links based on configured time durations, and the base station dynamically adjusts these time duration configurations based on traffic conditions and interference levels, enabling the system to adapt to changing communication requirements while maintaining reliability
2Productivity
If a multi-SIM UE uses multiple access links concurrently, then data transmission capability is improved, but resource interference increases
Solution Approach 1:
The patent applies segmentation by dividing the time resource into distinct time durations, each allocated to specific access links. Instead of allowing concurrent access on multiple links which causes interference, the time resources are segmented and assigned to different SIMs sequentially, enabling the UE to maintain multiple access link capabilities while eliminating resource interference through time-division multiplexing
Solution Approach 2:
The patent uses periodic action to structure the time durations for accessing different links in a repeating pattern. This periodic scheduling ensures that each access link receives dedicated time slots regularly, maximizing data transmission capability over time while preventing interference by ensuring that resource-intensive operations on different links do not occur simultaneously
3Productivity
If a multi-SIM UE allocates processing resources to multiple access links, then communication efficiency is improved, but resource management complexity increases
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously manage its own resource allocation across multiple access links based on pre-configured time durations. The UE independently switches between access links according to the configured schedule without requiring continuous network control, thereby improving communication efficiency while reducing the complexity of real-time resource management coordination

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first access link associated with a first subscriber identification module (SIM) of the UE. The UE may establish a second access link associated with a second SIM of the UE. The UE may identify a set of time durations during which to use the second access link. The UE may transmit an indication of the set of time durations to a base station. The UE may tune to the second access link to communicate with the base station during at least one of the set of time durations. Numerous other aspects are provided.
