PDSCH PROCESSING TIME CONSIDERATION FOR MULTI-CELL PDSCH SCHEDULING WITH A SINGLE DCI - A simplified explanation of the abstract

This abstract first appeared for US patent application 18365655 titled 'PDSCH PROCESSING TIME CONSIDERATION FOR MULTI-CELL PDSCH SCHEDULING WITH A SINGLE DCI

Simplified Explanation

The patent application describes processing time approaches for simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI in a wireless communication system.

  • Simultaneously scheduling multiple PDSCHs through a single DCI transmitted via a PDCCH, where each PDSCH is associated with a respective cell in a plurality of cells.
  • Transmitting data to or receiving data from a UE based on the scheduling information, with the PDSCHs occurring no earlier than a time offset following the PDCCH.
  • Receiving a HARQ-ACK via a PUCCH, sent by a UE in response to one of the PDSCHs, with the HARQ-ACK sent no earlier than a time offset following a reference time in one of the PDSCHs.
  • Transmitting data to or receiving data from a UE based on the scheduling information, with the PDSCHs occurring no earlier than a time offset following the PDCCH, allowing for analog beam switching by the UE.

Original Abstract Submitted

Described are processing time approaches to simultaneous multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In various approaches, simultaneously scheduling a plurality of physical downlink shared channels (PDSCHs) through a single DCI transmitted via a physical downlink control channel (PDCCH) occurs, wherein each of the plurality of PDSCHs is associated with a respective cell in a plurality of cells. The approaches further include transmitting data to or receiving data to a user equipment (UE) based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH. In other aspects, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) is received via a physical uplink control channel (PUCCH), the HARQ-ACK having been sent by a user equipment (UE) in response to one of the plurality of PDSCHs, wherein the HARQ-ACK is sent no earlier than a time offset following a reference time in one of the plurality of PDSCHs. In other aspects, transmitting data to or receiving data to a user equipment (UE) is based on the scheduling information, wherein the plurality of PDSCHs occurs no earlier than a time offset following the PDCCH, the time offset being configured to permit analog beam switching by a user equipment (UE).
