Transceiver Status Signaling Using Known Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing status signaling methods fail to function when one or both transceiver link partners are at bad operating points, preventing effective communication and data exchange due to inability to receive data.
Innovation Solution
A communication system that utilizes transmissions of known sequences to indicate the quality of operating points, where transceivers transmit specific sequences for predefined durations to signal good or bad operating conditions, allowing for faster recovery and maintaining data exchange performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If status signaling is used to control transceiver functions and monitor health information, then communication control and monitoring are improved, but the system fails when link partners are at bad operating points and cannot receive data
Solution Approach 1:
The patent applies preliminary action by transmitting known sequences before attempting normal data communication. These known sequences are sent in advance to establish a reliable communication baseline and enable the receiving transceiver to synchronize and equalize its receiver, ensuring the system is prepared for subsequent data exchange even when operating conditions are marginal or degraded.
Solution Approach 2:
The patent uses known sequences as an intermediary between the transmitting and receiving transceivers. These sequences serve as a mediator that facilitates the establishment of communication by providing a controlled, predictable signal that enables the receiving end to adjust its parameters and achieve proper synchronization before actual data transmission begins.
2Adaptability or versatility
If transceivers operate at bad operating points, then device operation flexibility is maintained, but data reception capability is lost
Solution Approach 1:
The transmitting transceiver sends known sequences in advance to enable the receiving transceiver to synchronize and equalize its receiver before data transmission. This preliminary action ensures that even when operating at degraded or marginal points, the receiving end can properly establish communication parameters and reliably receive subsequent data.
Solution Approach 2:
The patent implements feedback mechanisms where the receiving transceiver monitors the quality of received known sequences and provides status information back to the transmitting transceiver. This feedback loop allows the system to detect when operating points are degraded and trigger appropriate recovery actions, maintaining reliable data reception despite operating condition variations.
3Reliability
If known sequences are transmitted for synchronization and equalization, then communication establishment is improved, but transmission time and bandwidth usage increase
Solution Approach 1:
The patent employs periodic transmission of known sequences at strategically chosen intervals rather than continuous transmission. The sequences are sent periodically during link establishment phases or when recovery from degraded states is needed, balancing the need for reliable synchronization against the cost of transmission time and bandwidth consumption.

AI summary
System and method for utilizing transmission of known sequences to indicate qualities of operating points and fast recovery. One method includes the following steps: transmitting, by a first transceiver upon identifying quality degradation in operating point of the first transceiver, a 1st known sequence for a 1st duration; replying, by a second transceiver with a 2nd known sequence for a 2nd duration; transmitting, by the second transceiver upon identifying a quality degradation in operating point of the second transceiver, the 2nd known sequence for the 2nd duration, and replying, by the first transceiver, with the 1st known sequence for the 1st duration. Wherein the transceivers utilize the known sequences for recovering from the quality degradations faster than they could recover without receiving the known sequences.
