Satellite Soft Switch Resynchronization With Autonomous Timing Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, switching between satellite network entities results in increased signaling overhead due to synchronization timing adjustments, which can diminish user experience and efficiency.
Innovation Solution
User equipment (UE) autonomously adjusts synchronization timing using a time offset associated with a resynchronization operation, transmitting a capability message and receiving instructions to adjust timing before a reconfiguration message, thereby reducing the need for additional signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network entity controls synchronization timing adjustment through reconfiguration messages during satellite switches, then synchronization accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The UE autonomously adjusts synchronization timing before receiving the reconfiguration message by detecting the satellite switch and applying timing adjustment based on stored timing difference information. This preliminary action maintains synchronization accuracy while reducing the need for extensive network signaling during the switch.
Solution Approach 2:
The UE performs self-service by autonomously detecting satellite switches and adjusting its own synchronization timing without requiring real-time network control messages. The UE uses previously received timing difference information to make adjustments independently, thereby reducing signaling overhead while maintaining synchronization accuracy.
2Quantity of substance
If the UE autonomously adjusts synchronization timing without network instructions, then signaling overhead is reduced, but timing accuracy may deteriorate
Solution Approach 1:
The network entity performs preliminary action by providing timing difference information between satellites before the UE needs to make autonomous adjustments. This advance provision of timing data enables the UE to maintain accurate synchronization timing while operating autonomously, thus reducing signaling overhead without sacrificing timing precision.
Solution Approach 2:
The system implements feedback mechanisms where the UE monitors satellite signals and detects switches, then applies predetermined timing adjustments based on previously received timing difference information. This feedback-driven autonomous adjustment maintains timing accuracy while minimizing the need for continuous network signaling.
3Reliability
If reconfiguration messages are sent during satellite switches, then network control over synchronization is maintained, but communication efficiency decreases
Solution Approach 1:
The UE performs self-service by autonomously detecting satellite switches and adjusting synchronization timing using stored timing difference information. This self-service capability maintains network control reliability through predetermined timing parameters while significantly improving communication efficiency by eliminating the need for real-time reconfiguration messages during switches.
Solution Approach 2:
The network entity performs preliminary action by providing timing difference information in advance before switches occur. This advance preparation enables the UE to make autonomous adjustments without requiring real-time network control messages during switches, thereby maintaining reliability through pre-configured parameters while improving communication efficiency.

AI summary
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously adjust communication timings for resynchronization when performing a soft switch between satellite network entities. The UE may transmit a first message indicating a capability of the UE to autonomously adjust a synchronization timing in accordance with a resynchronization operation. Then, the UE may receive a second message based on the first message indicating the capability of the UE. The second message may instruct the UE to autonomously adjust the synchronization timing using a time offset associated with the resynchronization operation. The UE may autonomously adjust the synchronization timing in response to switching from communications with a first network entity to communications with a second network entity. The adjustment may occur prior to reception of a reconfiguration message.
