1Reliability
If individual power settings are configured for each beam, then signal quality is improved and interference is reduced, but device complexity increases
Solution Approach 1:
The power control function is segmented into two parts: the network node determines power-related configurations for multiple beams and sends them to the relay apparatus via signaling. The relay apparatus then applies these configurations to its beam transmissions. This segmentation allows complex power control to be managed centrally while simplifying the relay's operation.
Solution Approach 2:
The network node acts as an intermediary that determines and distributes power-related configurations to the relay apparatus. This intermediary approach enables centralized control of beam power settings without requiring the relay to independently manage complex power control algorithms, thus improving signal quality while managing complexity through external coordination.
2Productivity
If individual power settings are configured for each beam, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The power control functionality is divided between the network node (which determines configurations) and the relay apparatus (which applies them). This segmentation enables efficient communication through optimized beam power settings while concentrating the computational complexity in the network node rather than the relay.
Solution Approach 2:
The system implements feedback mechanisms where the relay apparatus reports beam quality metrics to the network node, which then adjusts power-related configurations accordingly. This feedback loop enables continuous optimization of communication efficiency while maintaining manageable complexity through automated adjustment rather than manual configuration.
