Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted through multiple component carriers to improve reliability, then data transmission reliability is improved, but device complexity increases due to the need to configure and manage multiple logical paths and identifiers
Solution Approach 1:
The patent segments the data transmission path by introducing separate logical paths for different data streams. Each logical path is identified by a unique identifier (LPI) and can be configured independently, allowing the system to manage multiple transmission paths through structured segmentation rather than monolithic complexity
Solution Approach 2:
The patent introduces control information as an intermediary mechanism that carries indicators about duplicated data transmission. This control information acts as a mediator between the base station and user equipment, enabling them to identify and properly process duplicated data without requiring complex direct coordination protocols
2Reliability
If duplicate data transmission is implemented across multiple carriers, then data decoding reliability is improved, but energy consumption increases due to transmitting the same data multiple times
Solution Approach 1:
The patent changes the transmission parameter by introducing a duplication indicator that specifies which data should be transmitted in duplicate. This allows flexible control over which data streams receive redundant transmission, enabling the system to optimize energy consumption by applying duplication only where necessary rather than universally
3Productivity
If multiple component carriers are used for data transmission, then transmission rate is improved, but latency increases due to the complexity of managing multiple carriers and logical paths
Solution Approach 1:
The patent applies preliminary action by pre-configuring logical paths and their identifiers before actual data transmission begins. The base station and user equipment establish the mapping between logical paths and component carriers in advance, eliminating the need for real-time path selection decisions that would cause latency

AI summary
The present invention relates to a method and a device for a base station transmitting/receiving data in a wireless communication system. According to the present invention, a method and a device may be provided by which a first message comprising first control information is received from a base station, wherein the first control information comprises a logical path identifier (ID) indicating a logical path for transmitting/receiving first data and second data, which is the same as the first data; as a response to the first message, a reply message is transmitted to the base station; and the first data and the second data are received on multiple component carriers (CC) associated with the logical path corresponding to the logical path ID.
