Wireless Re-synchronization Control for Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in efficiently managing power consumption and service quality due to asynchronous communication modes between communications apparatus and peer devices, particularly in scenarios with prolonged periods of no uplink or downlink data transmission, leading to potential misinterpretation by peer devices and increased power usage.
Innovation Solution
A communications apparatus equipped with a radio transceiver and processor that determines the need for re-synchronization based on specific rules, such as receipt of paging messages or lack of data transmission, and triggers procedures like extended service requests, random access requests, or tracking area updates to maintain synchronized communication modes and conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communications apparatus maintains continuous communication mode synchronization with the peer device, then service quality is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic synchronization checks at specific events (paging message reception, data transmission completion, timer expiration) rather than continuous monitoring. This event-driven periodic approach maintains synchronization reliability while significantly reducing power consumption by keeping the device in idle mode during non-critical periods.
Solution Approach 2:
The communications apparatus autonomously determines whether re-synchronization is needed based on pre-defined determination rules and automatically triggers re-synchronization procedures when necessary. This self-service mechanism eliminates the need for continuous peer device intervention while maintaining synchronization, thereby reducing overall power consumption.
2Reliability
If the communications apparatus frequently initiates re-synchronization procedures, then communication mode synchronization is improved, but service efficiency deteriorates
Solution Approach 1:
The patent pre-establishes determination rules that identify specific conditions triggering re-synchronization needs (paging message reception, data transmission completion, timer expiration). By preparing these rules in advance, the system avoids unnecessary re-synchronization procedures and triggers only when genuinely needed, thus maintaining synchronization reliability while preserving service efficiency.
3Device complexity
If the communications apparatus waits for peer device initiation of re-synchronization, then device complexity is reduced, but loss of information increases
Solution Approach 1:
The patent implements a feedback mechanism where the communications apparatus monitors its own communication state and peer device responses (paging messages, data transmissions) to determine when re-synchronization is needed. This self-feedback approach maintains synchronization without requiring complex peer-device-initiated control mechanisms, preventing communication mode asynchrony while keeping device complexity manageable.
Data Source
AI summary
A communications apparatus includes a radio transceiver and a processor. The radio transceiver is configured for transmitting or receiving wireless radio frequency signals to or from a peer device. The processor determines whether re-synchronization in a communication mode with the peer device is required according to a determination rule. When the re-synchronization is required, the processor transmits a message to the peer device via the radio transceiver to trigger a re-synchronization procedure. The processor determines whether the re-synchronization is required in a connected mode.
