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

This abstract first appeared for US patent application 17905215 titled 'METHODS FOR UPLINK CONTROL CHANNEL CARRIER SWITCHING

Simplified Explanation

The patent application discusses a method for PUCCH carrier switching at a UE, involving decoding an RRC configuration to determine a reference cell and a target PUCCH cell for PUCCH transmissions. The reference cell and target PUCCH cell have specific slot numerologies, and the determined slot is used for transmitting SR, CSI, or HARQ-ACK. The slot of the reference cell is mapped to the corresponding slot of the target PUCCH cell, and a PUCCH resource is determined for the transmission based on the target PUCCH cell's configuration.

Original Abstract Submitted

PUCCH carrier switching at a UE may include decoding an RRC configuration including a time-domain pattern indicating a reference cell and a target PUCCH cell for one or more PUCCH transmissions at a given point in time. The reference cell may include a reference cell slot numerology and the target PUCCH cell may include a target PUCCH cell slot numerology. A slot for PUCCH transmissions may be determined based on the reference cell slot numerology. The determined slot may be used for transmission of at least one of an SR, a CSI, and a HARQ-ACK. The determined slot of the reference cell may be mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource may be determined for performing a PUCCH transmission using the corresponding slot of the target PUCCH cell. The PUCCH resource determination may be based on a PUCCH configuration of the target PUCCH cell.
