Title:
TERMINAL, BASE STATION, INTEGRATED CIRCUIT, AND COMMUNICATIONS METHOD
Document Type and Number:
WIPO Patent Application WO/2015/020108
Kind Code:
A1
Abstract:
A terminal, a base station, an integrated circuit, and a communications method, whereby: search spaces for control channels monitored by the terminal are determined for each sub-frame, on the basis of a first uplink-downlink setting unique to the base station, a second uplink-downlink setting unique to the terminal, and at least one EPDCCH sub-frame setting; and scramble sequence parameters used for scrambling control channels in accordance with the search spaces for the control channels are switched. The terminal switches scramble sequence parameters in accordance with the search spaces and the sub-frame settings, and receives DMRS and descrambles EPDCCH by using the switched scramble sequence parameters.
