Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic beam activation commands and bandwidth part configurations are implemented, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic beam activation commands that allow base stations to activate or deactivate specific beams based on real-time traffic conditions and device capabilities. The bandwidth part configurations are dynamically adjusted according to network load and device requirements, enabling the system to adapt beam management strategies dynamically rather than using fixed configurations, thereby improving communication efficiency while managing complexity through automation.
Solution Approach 2:
The system changes key parameters such as beam activation status, bandwidth part allocation, and resource configuration based on traffic conditions and device capabilities. By modifying these parameters dynamically through control signals exchanged between base stations and wireless devices, the system optimizes communication efficiency without requiring complex manual intervention, resolving the contradiction between improved performance and system complexity.
2Reliability
If advanced beam management techniques are implemented, then network performance is improved, but ease of operation deteriorates
Solution Approach 1:
The beam management system operates autonomously by automatically selecting and activating appropriate beams based on pre-configured device capabilities and real-time network conditions. The base station independently determines optimal beam configurations without requiring manual intervention or complex user-side configuration, thereby maintaining high network performance while significantly improving ease of operation through self-service automation.
Solution Approach 2:
The system incorporates feedback mechanisms where wireless devices report their capabilities and network conditions are continuously monitored. This feedback information is used to automatically adjust beam configurations and resource allocation, ensuring optimal network performance while keeping the operation simple for users. The feedback loop enables the system to adapt automatically without requiring user involvement in complex beam management tasks.
3Adaptability or versatility
If heterogeneous networks with varying traffic loads are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the network into different bandwidth parts and beam groups that can be independently managed and activated. This segmentation allows the system to handle heterogeneous traffic loads by allocating specific segments to different service types or priority levels, improving network adaptability to varying conditions while reducing overall device complexity through modular resource management.
Solution Approach 2:
The system dynamically adjusts resource allocation strategies based on real-time traffic conditions and device capabilities in heterogeneous networks. By implementing dynamic beam activation and bandwidth part configuration, the network can adapt to different service requirements without requiring complex static planning, thereby improving adaptability while managing complexity through automated dynamic resource management.

AI summary
A wireless device receive one or more radio resource control (RRC) messages comprising one or more configuration parameters for a cell. The one or more configuration parameters indicate a sounding reference signal (SRS) resource indicator (SRI) for a configured uplink grant. The SRI indicates an SRS resource in an SRS resource set. The one or more configuration parameters comprise a parameter that enables using default transmission parameters for SRS transmissions. The one or more configuration parameters indicate no pathloss reference signal for physical uplink shared channel (PUSCH) transmissions. In response to the one or more configuration parameters comprising the parameter and no pathloss reference signal for the PUSCH transmissions, the wireless device transmits, with a transmission power determined based on a pathloss reference signal associated with the SRS resource set, a PUSCH transmission of the configured uplink grant.
