METHOD, DEVICE AND COMPUTER STORAGE MEDIUM FOR COMMUNICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18029156 titled 'METHOD, DEVICE AND COMPUTER STORAGE MEDIUM FOR COMMUNICATION

Simplified Explanation

This patent application is about methods, devices, and computer storage media for communication. It introduces a method for transmitting downlink control information (DCI) from a network device to a terminal device, scheduling a Physical Downlink Shared Channel (PDSCH), and receiving a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook.

  • The method involves transmitting DCI over a first set of Physical Downlink Control Channel (PDCCH) candidates to schedule a PDSCH.
  • The DCI includes at least one of a counter downlink assignment indicator (DAI) value and a total DAI value.
  • The PDSCH is then transmitted from the network device to the terminal device.
  • The terminal device generates a HARQ-ACK codebook for the PDSCH based on a first configuration of a second set of PDCCH candidates and the counter DAI value or the total DAI value.
  • This allows for obtaining a dynamic HARQ-ACK codebook without the need for additional signaling overhead.


Original Abstract Submitted

Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device to a terminal device, downlink control information (DCI) over a first set of Physical Downlink Control Channel (PDCCH) candidates for scheduling a Physical Downlink Shared Channel (PDSCH), where the DCI includes at least one of a counter downlink assignment indicator (DAI) value and a total DAI value; transmitting the PDSCH from the network device to the terminal device; and receiving a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the PDSCH from the terminal device, where the HARQ-ACK codebook is generated at least based on a first configuration of a second set of PDCCH candidates, and at least one of the counter DAI value and the total DAI value. As such, the dynamic HARQ-ACK codebook can be obtained without introducing additional signaling overhead.
