APERIODIC ZERO POWER CHANNEL STATE INFORMATION REFERENCE SIGNAL ENHANCEMENT FOR MULTI-SLOT PDSCH RATE MATCHING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240113831 titled 'APERIODIC ZERO POWER CHANNEL STATE INFORMATION REFERENCE SIGNAL ENHANCEMENT FOR MULTI-SLOT PDSCH RATE MATCHING
Simplified Explanation
The present disclosure introduces a more efficient rate matching technique by utilizing a triggered a-zp-csi-rs set to support rate matching around multiple slots. Additionally, the disclosure allows for the application of a triggered a-zp csi-rs set to less than all scheduled pdsch slots when dci schedules pdsch on multiple slots. The CSI-RS resource mapping can be extended to span multiple adjacent slots, and a resource mapping configuration can indicate an initial symbol of a plurality of symbols spanning the slots for a respective a-zp-csi-rs resource. This configuration enables a PDSCH transmission in a slot among the plurality of slots using a rate matching pattern associated with a set of a-zp-csi-re resources to be received. Furthermore, periodicity can be added to a-zp-csi-rs resource set configuration.
- Efficient rate matching using triggered a-zp-csi-rs set
