Abstract: A method is provided for determining transmit power of an uplink control channel of a user equipment to which two cells having different uplink (UL)-downlink (DL) configurations are assigned. A larger value between N1, the number of downlink subframes corresponding to a subframe n of a first cell having a first UL-DL configuration, and N2, the number of downlink subframes corresponding to a subframe n of a second cell having a second UL-DL configuration is chosen. A parameter value is determined based on the chosen value.

Abstract: A method and user equipment (UE) are provided for use in a time division duplexing (TDD)-based wireless communication system. A primary component carrier (PCC) and a secondary component carrier (SCC) are configured. The PCC and the SCC have different uplink-downlink (UL-DL) configurations. UE operations are performed under assumption that a physical downlink shared channel (PDSCH) is not received through any part of a downlink subframe in the SCC regardless of a length of a downlink pilot time slot (DwPTS) of a special subframe of the PCC, for a subframe #k where the PCC is the special subframe including the DwPTS, a guard period (GP), and an uplink pilot time slot (UpPTS), and the SCC is a downlink subframe.
