DAI AND CODEBOOK UPDATING FOR DCI SCHEDULING MULTIPLE CCS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17788669 titled 'DAI AND CODEBOOK UPDATING FOR DCI SCHEDULING MULTIPLE CCS

Simplified Explanation

The patent application describes a method, apparatus, and computer-readable medium for wireless communication at a user equipment and a base station. The abstract provides a brief overview of the implementation.

  • The method involves receiving a first downlink control information (DCI) on a physical downlink control channel (PDCCH) during a monitoring occasion. The DCI schedules a physical downlink shared channel (PDSCH) for multiple component carriers.
  • The DCI includes a counter downlink assignment index (DAI) that indicates the number of scheduled PDSCHs up to a certain point and a total DAI indicating the number of scheduled PDSCHs across the component carriers.
  • The user equipment then transmits a physical uplink control channel (PUCCH) that includes a position for hybrid automatic repeat request (HARQ)-Acknowledgement (ACK) bits corresponding to the PDSCH for each component carrier.

Potential Applications

  • This technology can be applied in wireless communication systems, particularly in user equipment and base stations.
  • It can be used in various wireless communication standards and protocols, such as 4G LTE and 5G.

Problems Solved

  • The technology addresses the need for efficient scheduling of multiple component carriers in wireless communication systems.
  • It solves the problem of managing and coordinating the transmission and reception of PDSCHs across different component carriers.

Benefits

  • The method allows for effective scheduling of PDSCHs for multiple component carriers, optimizing the use of available resources.
  • It improves the overall performance and efficiency of wireless communication systems by reducing interference and maximizing throughput.
  • The technology enhances the reliability and quality of communication by incorporating hybrid automatic repeat request (HARQ) mechanisms.


Original Abstract Submitted

Example implementations include a method, apparatus and computer-readable medium of wireless communication at a user equipment, including receiving on a physical downlink control channel (PDCCH) during a first PDCCH monitoring occasion a first downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH) for each of at least two component carriers, wherein the DCI includes a counter downlink assignment index (DAI) that indicates a number of scheduled PDSCHs up to a point that the first DCI was received and a total DAI indicating a number of scheduled PDSCHs across the at least two component carriers. The implementations further include transmitting a physical uplink control channel (PUCCH) including a position for hybrid automatic repeat request (HARQ)-Acknowledgement (ACK) bits corresponding to the PDSCH for each of the at least two component carriers. Also included is a corresponding a method, apparatus and computer-readable medium of wireless communication at a base station.
