Terminal Uplink Resource Selection in Cross-Duplex Sub-Bands

The patent segments the frequency spectrum into multiple sub-bands and divides transmission resources into different types (first type for UL, second type for DL, third type for flexible use). This segmentation allows simultaneous UL and DL transmissions in different sub-bands while maintaining reliable communication by avoiding conflicts in critical sub-bands.

The patent introduces dynamic resource allocation where the network device can flexibly configure transmission resources based on actual communication conditions. The terminal adapts its transmission parameters dynamically according to received configuration information, enabling the system to balance spectral efficiency and transmission reliability in real-time.

The patent uses parameter-based resource configuration where the network device configures transmission resources by changing parameters such as sub-band assignments, resource block allocations, and transmission timing. This approach enables flexible resource utilization while keeping the system manageable through standardized parameter interfaces.

The patent creates a universal resource configuration framework that can handle multiple transmission scenarios (UL, DL, flexible) using a unified set of configuration parameters. The third type transmission resource can be flexibly assigned to different purposes based on network conditions, providing multi-functionality without requiring separate dedicated mechanisms for each case.
