Radio Transceiver Chain Power Modes for Multi-RAT SIM Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face inefficiencies in power consumption and resource utilization due to frequent transitions between different radio access technologies (RATs), particularly when managing multiple subscriber identity modules (SIMs) supporting different RATs, leading to high processing costs and inefficient antenna element reconfiguration.
Innovation Solution
Implementing inter-SIM coordination techniques that allow devices to enter a light sleep mode instead of deep sleep, manage antenna subsets, and adjust active durations based on overlapping communication periods, thereby reducing unnecessary reconfigurations and optimizing power modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radio transceiver chain is frequently reconfigured for different RATs, then the device can support multiple radio access technologies, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the radio transceiver chain for different RATs and maintaining readiness through light sleep modes. The device monitors upcoming communication cycles in advance and keeps the transceiver in a low-power but ready state, avoiding full reconfiguration while ensuring rapid transition when needed. This resolves the contradiction by enabling multi-RAT support without frequent high-cost reconfigurations.
Solution Approach 2:
The patent implements dynamics by introducing multiple power modes (active, light sleep, deep sleep) that can be dynamically switched based on the operational state and upcoming communication cycles. The system adapts the power consumption level dynamically rather than using a fixed mode, allowing the transceiver to be fully configured when needed while minimizing power consumption during idle periods, thus resolving the adaptability-power consumption tradeoff.
2Adaptability or versatility
If antenna elements are frequently reconfigured, then the device can adapt to different communication technologies, but latency increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing configuration parameters for different RATs and keeping the antenna system in a partially configured state during light sleep modes. This allows the device to rapidly switch between technologies without performing full reconfiguration from scratch, thereby reducing latency while maintaining adaptability.
Solution Approach 2:
The patent segments the antenna configuration into essential components that remain active and non-essential components that can be quickly reconfigured. By maintaining the core antenna structure in a ready state while only adjusting specific configuration parameters, the system achieves rapid adaptation between RATs with minimal latency.
3Reliability
If communication cycles are managed independently, then each RAT can operate optimally, but resource utilization decreases
Solution Approach 1:
The patent merges the management of multiple RAT communication cycles into a unified framework that coordinates their operation. By combining the scheduling and power management functions, the system identifies overlapping cycles and consolidates operations, allowing multiple RATs to share common resources and reducing overall power consumption while maintaining optimal operation for each technology.
Solution Approach 2:
The patent implements feedback mechanisms that continuously monitor the operational status of different RATs and adjust the power modes and resource allocation accordingly. This feedback loop enables the system to optimize resource utilization by identifying when multiple RATs can operate simultaneously with shared resources versus when separate dedicated resources are needed, balancing reliability with productivity.

AI summary
A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.
