DYNAMIC UPLINK CONTROL CHANNEL CARRIER SWITCHING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240235748 titled 'DYNAMIC UPLINK CONTROL CHANNEL CARRIER SWITCHING

The patent application involves a method for PUCCH (Physical Uplink Control Channel) carrier switching in a wireless communication system.

• Decoding of an RRC (Radio Resource Control) configuration to determine a reference cell slot numerology.
• Determination of a reference cell slot for PUCCH transmissions based on the reference cell slot numerology.
• Usage of the determined slot for transmission of SR (Scheduling Request), CSI (Channel State Information), or HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement), as well as a DCI (Downlink Control Information) indicating a candidate target PUCCH cell.
• Decoding of the slot of the candidate target PUCCH cell with a candidate target PUCCH cell slot numerology.
• Determination of a target PUCCH cell slot numerology for transmitting the SR, CSI, or HARQ-ACK.
• Mapping of the determined slot to a corresponding slot of the target PUCCH cell.
• Determination of a PUCCH resource for transmitting the SR, CSI, or HARQ-ACK using the corresponding slot of the target PUCCH cell, based on the PUCCH configuration of the target PUCCH cell.

Potential Applications: - This technology can be applied in various wireless communication systems to optimize PUCCH transmissions. - It can improve the efficiency and reliability of uplink control channel communications in cellular networks.

Problems Solved: - Efficient switching of PUCCH carriers based on cell configurations. - Enhanced transmission of control information in wireless networks.

Original Abstract Submitted

pucch carrier switching includes decoding an rrc configuration that indicates a reference cell having a reference cell slot numerology. a reference cell slot is determined for pucch transmissions based on the reference cell slot numerology. the determined slot is used for transmission of an sr, csi, or harq-ack, a dci indicating a candidate target pucch cell having a candidate target pucch cell slot numerology and a slot of the candidate target pucch cell is decoded. a target pucch cell having a target pucch cell slot numerology is determined for transmitting the sr, the csi, or the harq-ack. the determined slot is mapped to a corresponding slot of the target pucch cell. a pucch resource is determined for transmitting the sr, the csi, or the harq-ack using the corresponding slot of the target pucch cell. the pucch resource determination is based on a pucch configuration of the target pucch cell.
