Abstract

A search space of a control channel which is monitored by a terminal is determined based on a first uplink-downlink configuration specific to a base station, a second uplink-downlink configuration specific to a terminal, and one or more EPDCCH subframe configuration, for each subframe. A scrambling sequence parameter which corresponds to the search space of the control channel and is used in scrambling of the control channel is switched. The terminal switches the scrambling sequence parameter, corresponding to the search space and a subframe configuration, and the terminal receives a DMRS and descrambles an EPDCCH by using the switched scrambling sequence parameter.
