Multi-Panel UE PUSCH Mapping for Simultaneous Codeword Transmission

The patent segments the resource element mapping process into two distinct mapping schemes: a first mapping scheme that maps coded bits to resource elements in order of antenna panel number, and a second mapping scheme that maps coded bits to resource elements in order of frequency. This segmentation allows the UE to handle different transmission scenarios (single codeword vs. multiple codewords, overlapping PUSCHs) by selecting the appropriate mapping scheme, thereby enabling simultaneous transmission of multiple codewords and overlapping PUSCHs while maintaining compliance with existing 3GPP standards.

The patent introduces dynamic selection capability between two mapping schemes based on the transmission scenario. The UE can dynamically determine which mapping scheme to use depending on whether it is transmitting a single codeword or multiple codewords simultaneously, and whether overlapping PUSCHs are present. This dynamic adaptability enables multi-panel UEs to efficiently utilize multi-TRP operations and improve network coverage and reliability while maintaining compatibility with existing specifications.

The patent changes the mapping parameter (order of resource element allocation) based on the transmission scenario. Instead of using a fixed mapping approach, the system switches between two parameter sets: panel-number-based ordering for certain scenarios and frequency-based ordering for other scenarios. This parameter change approach provides flexibility in resource element mapping while keeping the implementation relatively simple by only introducing two distinct mapping schemes rather than multiple complex ones.
