Uplink Channel Repetition Across FD and HD Time Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with full duplex (FD) and half duplex (HD) operations, the transition of uplink data channels across different symbol types leads to inconsistencies in frequency resources, transmission power, and beam usage, complicating PUSCH transmission.
Innovation Solution
A method is provided where a user equipment (UE) and base station configure parameters for uplink data channels based on FD and HD time resources, allowing repetition transmission or reception to be skipped on specific symbols, ensuring consistent frequency resources, power, and beam usage.

Engineering Contradiction Analysis
1Adaptability or versatility
If uplink data channel transmission uses both SBFD and non-SBFD symbols, then frequency resources and transmission parameters change depending on symbol type, but this increases transmission flexibility; however, it causes complexity in managing varying frequency resources, power, and beams across different symbol types
Solution Approach 1:
The patent segments the uplink data channel transmission by separating SBFD symbols and non-SBFD symbols into distinct transmission groups. The UE determines whether to transmit based on the symbol type composition of the entire uplink data channel, ensuring that transmission parameters remain consistent within each segment rather than varying across mixed symbol types.
Solution Approach 2:
Instead of adapting transmission parameters to match varying symbol types (the conventional approach), the patent inverts the logic by requiring uniform transmission parameters across all symbols and using parameter uniformity as the criterion to determine whether transmission should occur at all. This inversion simplifies the decision-making process.
2Reliability
If repetition transmission is performed across multiple slots containing different symbol types, then coverage is improved, but the varying frequency resources and transmission parameters across symbol types increase system complexity
Solution Approach 1:
The patent applies homogeneity by requiring that repetition transmissions use consistent transmission parameters (frequency resources, power, beams) across all symbols regardless of their SBFD or non-SBFD classification. This uniformity approach ensures that repeated transmissions maintain identical characteristics, simplifying system management while preserving coverage enhancement benefits.
3Productivity
If the system supports both full duplex and half duplex operations, then resource utilization efficiency is improved, but the coexistence of FD and HD time resources creates complexity in determining transmission parameters
Solution Approach 1:
The patent changes the fundamental parameter from variable transmission parameters (frequency, power, beam) to a binary transmission decision parameter. By transforming the problem from 'how to adjust parameters for each symbol type' to 'whether to transmit at all based on symbol composition,' the system maintains support for both FD and HD operations while simplifying parameter configuration.

AI summary
Provided are a method for operating a device and a device using same in a wireless communication system. The method involves: receiving information used in configuring parameters, applicable to a specific frequency band, of an uplink data channel; and performing repetitive transmission of the uplink data channel on the basis of the information. When, in the repetitive transmission, both a full duplex (FD) time resource and a half duplex (HD) time resource are included among time resources configured in order to transmit a specific uplink data channel, the transmission of the specific uplink data channel is skipped.
