Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single transmit power is used for all transmission occasions in a PDU set, then the device complexity is reduced and power control is simplified, but resource utilization becomes suboptimal and interference increases
Solution Approach 1:
The PDU set is segmented into multiple transmission occasions, and the transmit power is segmented into different power levels (first transmit power and second transmit power). Each transmission occasion is assigned to a specific power level based on the PDU subset being transmitted, enabling differentiated power control that optimizes resource utilization while maintaining manageable complexity through structured segmentation.
Solution Approach 2:
The transmit power is made dynamic by allowing it to vary across different transmission occasions within the same PDU set. The system dynamically selects between first transmit power and second transmit power based on the specific transmission occasion and PDU subset, enabling adaptive power control that responds to changing channel conditions and traffic requirements, thereby improving resource utilization.
2Device complexity
If a single transmit power is used for all transmission occasions in a PDU set, then the power control mechanism is simplified, but interference to other users increases
Solution Approach 1:
Different transmit powers are applied to different transmission occasions based on local conditions. The first transmit power is used for certain PDU subsets while the second transmit power is used for other PDU subsets, allowing the system to apply appropriate power levels locally to each transmission occasion, thereby reducing unnecessary interference while maintaining sufficient signal quality where needed.
3Productivity
If different transmit powers are used for different subsets of PDUs, then resource utilization is improved and interference is reduced, but the device complexity and power control mechanism complexity increase
Solution Approach 1:
The system segments the PDU set into different subsets that can be transmitted with different power levels. This segmentation approach structures the complexity by creating clear boundaries and rules for power assignment, making the power control implementation more manageable while still achieving the benefits of differentiated power control for improved resource utilization.
Solution Approach 2:
The transmit power parameter is changed across different transmission occasions based on the PDU subset being transmitted. By systematically varying this key parameter according to predefined rules and conditions, the system achieves improved resource utilization and interference reduction while keeping the control logic structured and manageable through parameter-based differentiation.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of transmission resources that are associated with multiple transmission occasions associated with a packet data unit (PDU) set. The UE may transmit or receive the PDU set by: transmitting or receiving a first subset of one or more PDUs, of the PDU set, using a first subset of one or more transmission occasions, wherein the first subset of one or more PDUs is associated with a first transmit power; and transmitting or receiving a second subset of one or more PDUs, of the PDU set, using a second subset of one or more transmission occasions, wherein the second subset of one or more PDUs is associated with a second transmit power different than the first transmit power. Numerous other aspects are described.
