TECHNIQUES FOR PDSCH/PUSCH PROCESSING FOR MULTI-TRP - A simplified explanation of the abstract

This abstract first appeared for US patent application 18670190 titled 'TECHNIQUES FOR PDSCH/PUSCH PROCESSING FOR MULTI-TRP

The patent application discusses techniques for processing the Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH) for multiple Transmission and Reception Points (multi-TRP).

• Determining PDSCH Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) processing timing involves identifying if a User Equipment (UE) is set up for single Downlink Control Information (single-DCI) multi-TRP PDSCH operation.
• The method includes determining the first PDSCH and second PDSCH within a slot, used in the single-DCI multi-TRP PDSCH operation.
• Minimum HARQ-ACK processing timing for the first and second PDSCH is determined using symbols from the first PDSCH or both the first and second PDSCH.

Original Abstract Submitted

Techniques for physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) processing for multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PDSCH hybrid automatic repeat request-acknowledgement (HARQ-ACK) processing timing may include determining that a user equipment (UE) is configured for single downlink control information (single-DCI) multi-TRP PDSCH operation, determining a first PDSCH and a second PDSCH within a slot, wherein the first PDSCH and the second PDSCH are used in the single-DCI multi-TRP PDSCH operation, and determining a minimum HARQ-ACK processing timing for the first PDSCH and the second PDSCH using one or more symbols of the first PDSCH or one or more symbols of both the first PDSCH and the second PDSCH.
