1Object-affected harmful factors
If conventional precoder determination methods are used, then device complexity is reduced, but interference between D2D and cellular communications increases
Solution Approach 1:
The system performs preliminary channel estimation and precoder determination before actual communication begins. By acquiring channel information and determining optimal precoders in advance, the system can minimize interference during resource sharing without increasing real-time processing complexity
Solution Approach 2:
The method incorporates feedback mechanisms where channel information is continuously monitored and used to adjust precoders. This feedback loop enables dynamic interference management while maintaining systematic complexity through automated closed-loop control
2Productivity
If wireless communication resources are shared between D2D and cellular communications, then productivity increases, but interference between different communication types worsens
Solution Approach 1:
The system applies different precoder strategies tailored to specific communication pairs and channels. By customizing precoders for individual D2D and cellular links based on their unique channel characteristics, the system maximizes resource sharing efficiency while minimizing pairwise interference
Solution Approach 2:
The method dynamically adjusts precoder parameters based on channel conditions, transmission power levels, and interference levels. By continuously optimizing these parameters, the system enables efficient resource sharing between D2D and cellular communications while maintaining low interference through adaptive parameter modification
