Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UL transmission is performed using multiple panels to improve throughput, then system capacity and data rate are improved, but control complexity and difficulty of managing transmission timing increase
Solution Approach 1:
The patent segments the uplink transmission control into separate UE operations for different panels. Each panel's transmission is controlled independently with specific timing rules, allowing the terminal to manage multiple panels without overwhelming complexity. The control section divides the transmission management into discrete operational units that can be handled separately.
Solution Approach 2:
The patent implements dynamic control of uplink transmission timing based on the specific configuration of each panel and the current transmission state. The control section adapts the transmission timing and ordering dynamically according to the panel configuration indicated by downlink control information, allowing flexible adjustment without fixed rigid constraints.
2Productivity
If simultaneous UL transmission using multiple panels is supported to increase capacity, then system capacity is improved, but reliability of transmission control deteriorates due to insufficient control mechanisms
Solution Approach 1:
The patent employs feedback mechanisms where the base station provides downlink control information that indicates the configuration of each panel. The terminal uses this feedback to determine the appropriate UE operations and transmission timing for each panel, ensuring reliable control through continuous information exchange and adaptation based on network instructions.
Solution Approach 2:
The terminal's control section autonomously determines the transmission timing and ordering for multiple panels based on the received downlink control information and predefined UE operations. This self-service capability allows the terminal to independently manage its own multi-panel transmissions without requiring complex external coordination for each transmission event.
3Productivity
If multiple UE operations are defined for multi-panel transmission to improve throughput, then data rate is improved, but difficulty of detecting and measuring transmission timing increases
Solution Approach 1:
The patent changes the parameter of transmission timing by defining specific UE operations that alter timing behavior based on panel configuration. Different UE operations correspond to different timing parameters, allowing the system to adjust transmission timing as a variable parameter rather than a fixed value, thereby simplifying detection and measurement through standardized operational modes.

AI summary
A terminal according to an aspect of the present disclosure includes: a receiving section that receives first downlink control information for scheduling a first UL channel and second downlink control information for scheduling a second UL channel; and a control section that controls at least one of application of first UE operation related to transmission of the first channel and transmission of the second channel in a time domain and application of second UE operation related to order of transmission of each of the downlink control information and each of the UL channels, based on whether or not respective panels or transmission/reception points (TRPs) corresponding to the first downlink control information and the second downlink control information are same.
