Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, the inconsistent configuration of multiple types of time-domain units in sub-band full duplex (SBFD) technology leads to unclear data transmission protocols, causing potential transmission failures between terminal devices and network devices.
Innovation Solution
A method and apparatus that determine a single type of time-domain unit for data transmission, including determining a time-domain unit and transmission parameters based on the configured unit, ensuring consistent understanding between terminal and network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of time-domain units are configured in SBFD technology, then the system can support diverse transmission scenarios (uplink, downlink, flexible symbols), but the inconsistent configuration leads to unclear data transmission protocols and potential transmission failures
Solution Approach 1:
The patent segments the time-domain unit into distinct symbol types (uplink symbols, downlink symbols, flexible symbols) with clearly defined functions. Each symbol type is independently configured and managed, allowing the system to support diverse transmission scenarios while maintaining clear boundaries and protocols for each segment, thereby preventing configuration inconsistencies.
2Adaptability or versatility
If multiple types of time-domain units are configured, then the system can accommodate different transmission directions, but the terminal device and network device may have inconsistent understanding of the configuration
Solution Approach 1:
The patent implements a feedback mechanism where the network device provides configuration information to the terminal device through downlink control information (DCI), and the terminal device confirms receipt and understanding of the configuration. This feedback loop ensures both devices have consistent understanding of the time-domain unit configurations, preventing misinterpretation while maintaining flexible transmission directions.
3Reliability
If a single type of time-domain unit is used for data transmission, then transmission failures are prevented and reliable communication is maintained, but the system cannot support sub-band full duplex technology with multiple transmission directions
Solution Approach 1:
The patent applies local quality by assigning different properties to different symbols within the time-domain unit. Each symbol is designated with specific characteristics (uplink, downlink, or flexible) appropriate for its intended transmission direction. This allows the system to maintain high reliability for each individual symbol while supporting diverse transmission directions across the overall time-domain structure.

AI summary
This disclosure discloses a transmission method and apparatus, a device, a storage medium, and a product, and relates to the field of communication technology. The method includes the following. A time-domain unit configured for a first transmission is determined. The time-domain unit configured for the first transmission contains one type of time-domain unit. In this method, when one or more types of time-domain unit exist, the one type of time-domain unit for the first transmission is determined based on the time-domain unit configured for the first transmission. As such, during the first transmission, the transmission can be performed according to the determined one type of time-domain unit, thereby avoiding failure of the first transmission due to inconsistent understanding between a terminal device and a network device when multiple types of time-domain unit exist at the same time.
