Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink control channel multiplexing is implemented across multiple TRPs/panels, then communication efficiency and resource utilization are improved, but device complexity increases
Solution Approach 1:
The patent segments the uplink control channel transmission by dividing it into multiple parts that can be transmitted through different TRPs/panels. Each segment carries control information for specific downlink transmissions, allowing parallel processing and improving overall communication efficiency without requiring a complete system redesign.
Solution Approach 2:
The patent creates a universal multiplexing mechanism that can handle multiple TRPs/panels through a single control channel structure. The same control channel format and multiplexing procedure work across different TRP configurations, reducing device complexity while maintaining high efficiency through flexible resource allocation.
2Quantity of substance
If uplink control channel multiplexing is implemented across multiple TRPs/panels, then resource utilization is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation where the control channel can adaptively select which TRPs/panels to multiplex based on current system conditions. This dynamic approach optimizes resource utilization by activating only the necessary TRPs for each transmission scenario, avoiding the complexity of managing all TRPs simultaneously.
Solution Approach 2:
The patent uses parameter changes in the control channel format and multiplexing configuration to adapt to different TRP/panel setups. By modifying parameters such as time-frequency resource allocation and multiplexing patterns rather than changing the fundamental system architecture, the patent achieves high resource utilization with minimal increase in device complexity.

AI summary
A method for uplink control multiplexing of a physical uplink control channel (PUCCH) repetition may include transmitting, by a base station to a wireless device, a first message indicating PUCCHs for repetitions of uplink control information (UCI). The method may also include transmitting, by the base station, a second message indicating a number of repetitions of a transport block via physical uplink shared channels (PUSCHs) and indicating a beta offset for multiplexing the UCI via a PUSCH of the PUSCHs. The method may further include receiving, based on a coding rate that has been determined, based on the beta offset and the number of repetitions, and in response to the PUCCHs overlapping with the PUSCHs in at least one symbol, the UCI and the transport block multiplexed in the PUSCHs.
