1. A method comprising:
transmitting, by a base station, configuration parameters indicating:
a first index for determining a first position of a first bit of a first transmit power control (TPC) command, in a first downlink control information (DCI), that is applicable to a first cell; and
a second index for determining a second position of a first bit of a second TPC command, in the first DCI, that is applicable to a second cell;
wherein:
the first cell and the second cell are in a physical uplink control channel (PUCCH) group;
the first cell is:
a primary cell (PCell) in case the PUCCH group is a primary PUCCH group; and
is a PUCCH secondary cell (PUCCH-SCell) in case the PUCCH group is a secondary PUCCH group;
the second cell:
is not the PCell and is not the PUCCH-SCell; and
is configured on top of the first cell for PUCCH cell switching in the PUCCH group; and
based on the PUCCH cell switching and in a transmission timing, one of the first cell and the second cell is the cell for PUCCH transmission in the PUCCH group;
transmitting the first DCI;
receiving uplink control information via a PUCCH, wherein a transmission power of the PUCCH is based on:
the first TPC command in response to the first cell being the cell for uplink control channel transmission in the transmission timing; and
the second TPC command in response to the second cell being the cell for uplink control channel transmission in the transmission timing.
