Abstract
Method and apparatus of primary cell indication for enhanced control channel demodulation method and apparatus are disclosed. Control information receiving method in a multi-distributed node system includes demodulating a first cell identification (ID) based on a synchronization signal (SS), demodulating information indicating a second cell ID based on a radio resource control (RRC) message and demodulating enhanced physical downlink control channel (e-PDCCH) based on the second cell ID, Accordingly, it may be possible to reduce complexity that occurs when the optimal prediction motion vector is induced and to enhance efficiency.

13. A method for receiving a downlink control channel in a wireless communication system, the method performed by a user equipment comprising:
-
receiving synchronization signals from a serving cell; determining a physical cell identity of the serving cell based on the synchronization signals; performing blind decoding in a first search space to find a first Physical Downlink Control Channel (PDCCH); receiving a Radio Resource Control (RRC) message including configuration information from the serving cell, the configuration information including information on a second search space and identity information, performing blind decoding in the second search space to find a second PDCCH, wherein the first PDCCH is demodulated based on the physical cell identity, and wherein the second PDCCH is demodulated based on the identity information. - View Dependent Claims (14, 15, 16, 17, 18)
