Splitting DCI for RedCap UE Power Saving

The patent segments the scheduling information into two distinct parts: common scheduling information transmitted via PDCCH and UE-specific scheduling information transmitted via PDSCH. RedCap UEs only need to monitor the PDCCH for common scheduling information, which is less frequent and requires less power, while UE-specific information is delivered through the PDSCH channel. This segmentation allows UEs to reduce PDCCH monitoring activity and thus lower power consumption while maintaining reliable scheduling through the combination of both channels.

The patent extracts the UE-specific scheduling information from the PDCCH channel and relocates it to the PDSCH channel. Only common scheduling information remains on the PDCCH. This extraction reduces the amount of data burden on the PDCCH, thereby lowering the blocking probability for control channel resources while ensuring that critical common scheduling information is reliably delivered. The UE-specific information is then transmitted through the data channel PDSCH, which has greater capacity and different resource allocation mechanisms.

The patent employs universal signaling mechanisms where the common scheduling information on PDCCH contains configuration parameters that apply to multiple UEs or groups of UEs. The UE-specific information on PDSCH uses standardized data channel processing procedures that are already widely implemented in 5G systems. By leveraging existing multi-functionality of the PDSCH channel (which can carry both user data and control information) and using standardized signaling formats, the patent achieves power saving through differentiated information delivery without introducing excessive system complexity.
