1Productivity
If time-frequency resources are shared between physical control channels and data channels, then resource utilization efficiency is improved, but resource overlap and interference occur
Solution Approach 1:
The patent segments time-frequency resources into distinct resource sets for control channels and data channels. By dividing the overall resource pool into separate controllable units, the system can allocate resources without overlap while maintaining high utilization efficiency. This segmentation allows independent management of control and data resources, preventing interference.
Solution Approach 2:
The patent implements dynamic resource allocation where the base station can flexibly adjust time-frequency resource assignments based on real-time traffic conditions and channel states. This dynamic approach allows the system to optimize resource utilization while avoiding conflicts through adaptive scheduling, rather than using fixed static allocation.
2Productivity
If the number of OFDM symbols for uplink and downlink is varied according to data traffic directions, then data processing efficiency is improved, but slot configuration complexity increases
Solution Approach 1:
The patent employs dynamic TDD where the number of OFDM symbols for uplink and downlink is flexibly adjusted based on real-time traffic demands. This allows the system to optimize data processing efficiency by allocating more symbols to the direction with higher traffic, while the base station manages the configuration complexity through centralized control.
Solution Approach 2:
The system uses feedback mechanisms where the base station monitors data traffic directions and dynamically adjusts slot configurations accordingly. This feedback loop allows efficient adaptation to changing traffic patterns while the base station handles the complexity of configuration management, keeping terminal devices simple.

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 achieve both extended transmission distance and high data rates in mmWave communication. By merging these techniques, the system leverages the directional gain of beamforming with the spatial multiplexing capability of massive MIMO, achieving superior performance while managing complexity through integrated design.
Solution Approach 2:
The system implements multi-functional antenna arrays that can perform both beamforming operations and MIMO spatial processing. This universal approach allows the same hardware infrastructure to provide multiple functions (directional transmission, spatial diversity, multiplexing), reducing overall system complexity compared to separate dedicated systems for each function.

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 a base 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.
