WIRELESS COMMUNICATION METHODS AND USER DEVICES FOR TRANSMISSION ACROSS DIFFERENT BANDWIDTHS

Abstract

The invention relates to a method of wireless communication, performed by user equipment (UE), for transmitting over different bandwidth parts (BWP) including the following steps: receiving, radio resource control (RRC) information to configure the first physical uplink control channel configuration (PUCCH-Config) for the first bandwidth part (BWP) of the first cell and the second PUCCH-Config for the second BWP UL of the second cell; receiving, from the first cell, downlink control information (DC1) including fields to indicate the time interval and switching indication; and transmit the PUCCH on the BWP UL of the second cell after receiving the DCI if the switching indication indicates the second cell.
