1Length of stationary object
If beam transmission is used for high-frequency communication, then transmission distance can be increased, but omnidirectional coverage cannot be achieved
Solution Approach 1:
The patent divides the coverage area into multiple sectors, each served by a separate beam transmission mode. Instead of using a single omnidirectional beam, the system segments the service area and assigns different transmission modes to different spatial regions, thereby achieving both extended transmission distance in each sector and comprehensive omnidirectional coverage through the combination of multiple sectors.
2Productivity
If different transmission modes are used for uplink and downlink signals, then signal transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the network device determines transmission modes for uplink signals based on the transmission modes used for downlink signals. The network device provides feedback information to the terminal device, enabling the terminal to select appropriate uplink transmission modes. This feedback-based approach optimizes signal transmission efficiency while reducing device complexity by centralizing the decision-making process in the network device.
