Title:
METHOD AND APPARATUS FOR PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) CARRIER SWITCHING IN MOBILE COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2022/233315
Kind Code:
A1
Abstract:
Various solutions for physical uplink control channel (PUCCH) carrier switching for hybrid automatic repeat request (HARQ) feedback with respect to user equipment (UE) and network apparatus in mobile communications are described. An apparatus, such as a UE, may receive a physical downlink control channel (PDCCH) on a first component carrier (CC). The apparatus may receive a physical downlink shared channel (PDSCH) on the first CC scheduled by the PDCCH. The apparatus may determine a second CC to transmit a physical uplink control channel (PUCCH) according to a configuration for PUCCH carrier switching. The apparatus may determine a slot offset subsequent to the PDSCH reception according to a first numerology of the first CC or a second numerology of the second CC. The apparatus may transmit the PUCCH corresponding to the PDSCH on the second CC according to the slot offset.
