Claim of US Patent No. 9,832,733

9. A user equipment, comprising a memory configured to store computer readable instructions and a processor, wherein the processor
executes the computer readable instructions to:
determine transmit power control-radio network temporary identifiers corresponding to respective sets of carriers and transmit
power control-indexes corresponding to the respective sets of carriers, wherein Physical Uplink Control Channels are transmitted
on different uplink carriers corresponding to different sets of carriers;

detect physical downlink control channels using the downlink control information format 3/3A and scrambled with the transmit
power control-radio network temporary identifiers corresponding to the respective sets of carriers in a common search space
of a primary component carrier; and

determine the locations, of uplink transmit power control commands corresponding to the respective sets of carriers, in the
detected physical downlink control channels scrambled with the transmit power control-radio network temporary identifiers
corresponding to the sets of carriers according to the transmit power control-indexes corresponding to the sets of carriers,
and obtain the uplink transmit power control commands corresponding to the sets of carriers at the corresponding locations.
