Dual Subscription Prioritization in Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems with dual subscriptions face interference and reduced performance due to conflicting time slots, leading to increased latency and reduced transmission capacity when communicating with multiple networks simultaneously.
Innovation Solution
A wireless device prioritizes one subscriber over another in conflicting time slots by configuring semi-static or dynamic scheduling, allowing for uplink or downlink transmissions based on the prioritization, and reports this information to the base station for adjusted scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless device communicates with multiple networks simultaneously using dual subscriptions, then the device can access multiple channels and improve communication versatility, but interference increases and communication performance deteriorates
Solution Approach 1:
The patent segments the communication resources by dividing time slots into different categories (first set of slots for first subscription, second set of slots for second subscription) and assigns different communication directions (uplink/downlink) to different segments. This segmentation prevents simultaneous conflicting transmissions and reduces interference while maintaining dual subscription capability.
2Productivity
If the device communicates in different directions at the same time for different subscriptions, then transmission capacity increases, but interference increases and performance reduces
Solution Approach 1:
The patent segments time resources into distinct sets of slots assigned to different subscriptions with specific communication directions. By controlling which subscription communicates in which direction during specific time segments, the system maintains high transmission capacity while preventing harmful interference from simultaneous bidirectional communications.
3Reliability
If the device prioritizes one subscriber over another in conflicting time slots, then communication reliability for the prioritized subscriber improves, but the non-prioritized subscriber experiences increased latency
Solution Approach 1:
The patent applies preliminary action by pre-configuring slot sets and communication directions for each subscription before conflicts occur. The device determines in advance which subscription should communicate in which direction during specific time slots, allowing proactive resolution of potential conflicts and ensuring reliable communication for prioritized subscriptions while minimizing latency through预先 arranged schedules.
4Productivity
If the device uses semi-static or dynamic scheduling configurations, then communication performance improves through optimized slot allocation, but device complexity increases
Solution Approach 1:
The patent implements dynamics by providing both semi-static and dynamic scheduling options. The device can adapt its slot configuration and communication direction assignments based on current network conditions and subscription priorities. This dynamic approach optimizes communication performance while managing device complexity through flexible, condition-based adjustment rather than rigid fixed configurations.

AI summary
Methods, systems, and devices for wireless communications are described that provide for a wireless device with dual subscriptions to prioritize a subscriber. A user equipment (UE) may configure a first channel for a first subscription and a second channel for a second subscription. The UE may determine one or more slots for the first subscription for communicating in a first direction and for the second subscription for communicating in a second direction, where the first and second directions are different. The UE may prioritize communications of the first subscription according to the determined slots. The prioritizing may be based on the direction, whether the communications are scheduled or configured, or whether the slot includes a monitoring occasion. The UE may communicate in the first direction according to the first subscription.
