PHYSICAL UPLINK CONTROL CHANNEL CARRIER SWITCH WITH MULTIPLE HYBRID AUTOMATIC REPEAT REQUEST ACKNOWLEDGEMENT CODEBOOKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18055963 titled 'PHYSICAL UPLINK CONTROL CHANNEL CARRIER SWITCH WITH MULTIPLE HYBRID AUTOMATIC REPEAT REQUEST ACKNOWLEDGEMENT CODEBOOKS

Simplified Explanation

The patent application relates to wireless communication and specifically to a method for enabling physical uplink control channel (PUCCH) carrier switching in a user equipment (UE).

  • The UE receives a configuration of two HARQ-ACK codebooks, indicating that PUCCH carrier switching is enabled for at least one of them.
  • The UE receives an indication of a PUCCH carrier switch for the enabled codebook.
  • The UE receives a downlink communication associated with the enabled codebook.
  • The UE transmits HARQ feedback to a target PUCCH carrier based on the indication of the PUCCH carrier switch.

Potential applications of this technology:

  • Improved wireless communication in scenarios where PUCCH carrier switching is necessary.
  • Enhanced reliability and efficiency of HARQ feedback transmission in wireless networks.

Problems solved by this technology:

  • Addressing the need for PUCCH carrier switching in certain wireless communication scenarios.
  • Ensuring accurate and timely HARQ feedback transmission in the presence of PUCCH carrier switching.

Benefits of this technology:

  • Improved overall performance and reliability of wireless communication systems.
  • Enhanced flexibility in managing PUCCH carrier switching for HARQ-ACK codebooks.
  • Increased efficiency in HARQ feedback transmission.


Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook and a second HARQ-ACK codebook, wherein the configuration indicates that physical uplink control channel (PUCCH) carrier switching is enabled for at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive an indication of a PUCCH carrier switch for the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may receive a downlink communication associated with the at least one of the first HARQ-ACK codebook or the second HARQ-ACK codebook. The UE may transmit HARQ feedback a target PUCCH carrier based at least in part on the indication of the PUCCH carrier switch. Numerous other aspects are described.
