Relay Terminal Inter-System Communication Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional inter-system communication methods, the probability of correct receipt of relay information by a neighboring base station is low due to channel attenuation and the lack of synchronization and power adjustment between the relay terminal and the neighboring base station.
Innovation Solution
The relay terminal accesses the neighboring base station before transmitting relay information, performing synchronization and power adjustment to improve the probability of correct receipt, and maintains communication with both the serving and neighboring base stations using allocated resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay terminal transmits relay information directly to the neighboring base station without accessing synchronization and power adjustment, then the transmission process is simple and fast, but the probability of correct receipt is very low due to channel attenuation
Solution Approach 1:
The relay terminal performs access synchronization and power adjustment with the neighboring base station before transmitting the relay information. This preliminary action establishes the necessary communication parameters and optimization conditions in advance, ensuring that when the relay information is transmitted, the receiving end is already prepared with the correct synchronization state and power settings, thereby significantly improving the probability of correct receipt.
2Reliability
If the relay terminal performs access synchronization and power adjustment with the neighboring base station, then the probability of correct receipt is improved, but the time required for transmission increases
Solution Approach 1:
The access synchronization and power adjustment are performed in advance before the actual relay information transmission. By completing these preparatory actions beforehand, the system optimizes the transmission conditions so that the subsequent relay information can be transmitted efficiently without needing to repeat the synchronization and power adjustment processes during the actual data transmission phase.
3Ease of operation
If the serving base station allocates relay signal transmission resources including time and frequency resources, then the relay terminal can transmit uplink signals, but the neighboring base station cannot know where to receive and how to demodulate and decode the uplink signal
Solution Approach 1:
The relay terminal feeds back the allocated time and frequency resources to the neighboring base station through the access synchronization process. This feedback mechanism ensures that the neighboring base station receives accurate information about where and how to receive the relay information, enabling it to properly demodulate and decode the uplink signal from the relay terminal.
