Master-Slave Link Initialization with Separate Sync and Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization process between master and slave nodes in a communication system is prolonged or fails due to bit negation information in scrambling codes, affecting synchronization efficiency.
Innovation Solution
A method where synchronization information is sent separately from training information frames, ensuring the synchronization information receiving node can quickly synchronize, and training information frames are structured to include specific parameters for efficient link training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If synchronization information is combined with training information frames, then link training can be performed efficiently, but synchronization efficiency deteriorates due to additional bit identification requirements
Solution Approach 1:
The patent divides the information transmission into two independent phases: a synchronization phase where only synchronization information is transmitted without training information, and a link training phase where training information frames are transmitted. This segmentation allows the receiving node to complete synchronization quickly without being delayed by training information processing, while still enabling efficient link training in the second phase.
Solution Approach 2:
The patent performs synchronization information transmission before link training. By completing the synchronization phase in advance, the receiving node is fully synchronized and ready to receive training information frames without delay. This preliminary synchronization action eliminates the need for the receiving node to identify additional bits during the training phase, as synchronization is already established.
2Adaptability or versatility
If additional bits are added to information frames for training purposes, then training functionality is enhanced, but synchronization reliability deteriorates due to bit identification difficulties
Solution Approach 1:
The patent separates synchronization information from training information into distinct transmission phases. During the synchronization phase, only synchronization information is transmitted without additional training bits, ensuring clear and reliable synchronization. The training functionality is then implemented in a separate phase using training information frames, which may include additional bits for training purposes but do not interfere with the already-established synchronization.
3Adaptability or versatility
If scrambling codes include bit negation information, then communication capabilities are enhanced, but synchronization efficiency deteriorates due to prolonged synchronization time
Solution Approach 1:
The patent transmits synchronization information before training information frames. This preliminary synchronization action allows the receiving node to establish synchronization using only the synchronization information without being affected by the bit negation information in subsequent training frames. The synchronization is completed in advance, so the training phase can proceed efficiently without prolonging synchronization time.

AI summary
A communication link initialization method includes that a master node sends a first information frame to a slave node. The first information frame includes first synchronization information. The slave node implements synchronization with the master node based on the first synchronization information. The slave node sends a second information frame to the master node. The second information frame includes second synchronization information. The master node implements synchronization with the slave node based on the second synchronization information. The master node sends a third information frame to the slave node. The third information frame is used to indicate a first training information frame. The slave node trains a link between the master node and the slave node based on the third information frame. The slave node sends a fourth information frame to the master node.
