Uplink Resource Selection for PUSCH-PUCCH Collision in Terminals

The patent segments the resource selection process into two independent stages: first determining whether PUSCH resources can be used based on collision conditions, then selecting specific PUSCH resources based on priority. This segmentation allows PUSCH resources to be utilized whenever possible (improving utilization) while still applying priority rules in the selection stage (ensuring transmission priority).

The patent introduces dynamic adjustment of resource selection based on collision detection. When PUSCH and PUCCH resources collide, the system dynamically evaluates whether the PUSCH resource can be used instead of automatically prioritizing PUCCH, allowing flexible adaptation to different scenarios while maintaining priority requirements.

The patent inverts the traditional priority comparison approach. Instead of comparing PUSCH and PUCCH priorities and selecting the higher priority resource, it first checks whether PUSCH resources can be used (inverting the traditional PUCCH-first approach), and only if they cannot be used does it fall back to PUCCH transmission. This inversion allows PUSCH resources to be utilized whenever possible while still ensuring control channel transmission when necessary.

The patent converts the potential harm of resource collision into benefit by allowing PUSCH resources to be used even when they collide with PUCCH resources, under certain conditions. This transforms the previously harmful collision scenario into an opportunity for improved resource utilization, while still maintaining the reliability of control channel transmission when absolutely necessary.
