1Length of stationary object
If beamforming is applied to control channels in mmWave-band wireless communication, then transmission distance and coverage are improved, but device complexity and resource allocation difficulty increase
Solution Approach 1:
The patent divides the control channel resource pool into multiple beam-specific resource pools, where each pool corresponds to a specific transmit beam. This segmentation allows the system to manage beams independently, reducing the overall complexity by breaking down the large-scale beam management problem into smaller, more manageable subsets.
Solution Approach 2:
The patent performs beam management and resource allocation in advance by pre-configuring beam-specific resource pools and determining optimal beams before control channel transmission. This preliminary action reduces real-time complexity by avoiding dynamic beam selection during transmission.
2Object-generated harmful factors
If beamforming is applied to control channels, then signal directivity and interference reduction are improved, but resource allocation complexity and system overhead increase
Solution Approach 1:
The patent segments the control channel resources into beam-specific pools, where each pool is dedicated to a specific transmit beam. This segmentation reduces interference by isolating beams in separate resource pools while simplifying resource allocation by providing clear, pre-defined resource assignments for each beam, thereby reducing the complexity of managing beam-specific resources.
3Productivity
If conventional isotropic transmission is used for control channels, then system simplicity is maintained, but transmission efficiency and coverage in mmWave band deteriorate
Solution Approach 1:
The patent divides control channel resources into beam-specific segments, enabling efficient use of beamforming by directing resources along specific spatial paths. This segmentation improves transmission efficiency in mmWave band by utilizing the directional nature of beamforming while managing complexity through structured resource organization.
Solution Approach 2:
The patent changes the transmission parameter from isotropic (omnidirectional) to beamformed (directional) by introducing beam-specific resource pools and adjusting resource allocation based on beam characteristics. This parameter change improves transmission efficiency by matching the directional nature of mmWave propagation while maintaining manageable complexity through systematic resource organization.
