1Productivity
If dynamic TDD is used to vary the number of OFDM symbols according to data traffic directions, then data throughput is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic TDD by allowing the base station to vary the number of downlink and uplink OFDM symbols in different slots according to real-time data traffic conditions. The slot configuration is dynamically adjusted based on traffic direction (downlink-heavy or uplink-heavy), enabling the system to adapt resource allocation to changing data throughput requirements without fixed rigid structures.

If beamforming and massive MIMO technologies are used to alleviate path loss in mmWave band, then transmission distance is improved, but system complexity increases
Solution Approach 1:
The patent combines beamforming and massive MIMO technologies to address path loss in the mmWave band. By merging these two techniques, the system achieves extended transmission distance through directional beam focusing while utilizing multiple antennas for spatial diversity and multiplexing, thereby overcoming the limitations of single-technique approaches in high-frequency wireless communication.
3Productivity
If time-frequency resources are optimized for physical data channel reception, then data transmission efficiency is improved, but resource overlap handling complexity increases
Solution Approach 1:
The patent segments time-frequency resources into distinct resource sets for different purposes (e.g., control channels, data channels, reference signals). By dividing the overall resource space into manageable segments with specific functions, the system can optimize each segment independently while handling overlaps through predefined segmentation rules, thereby improving data transmission efficiency without excessive complexity.

AI summary
A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module; and a processor configured to control the communication module. The processor receives a radio resource control (RRC) signal from abase station of the wireless communication system through the communication module and determines a time-frequency resource corresponding to at least one resource-set indicated by the RRC signal. The processor receives a physical control channel from the base station through the communication module, determines a time-frequency resource domain in which physical data channel reception of the terminal is scheduled by the physical control channel, and receives a physical data channel based on a time-frequency resource in which the physical data channel reception of the terminal is scheduled and a time-frequency resource in which the at least one resource-set overlap. The resource-set is a set of time-frequency resources.
