1. A method of receiving a control channel, which is received by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a physical broadcast channel (PBCH) in 4 frames from an eNodeB;
determining a transmission mode and a number of antenna ports based on a combination of a first cyclic redundancy check (CRC) masked to the PBCH in a first frame among the 4 frames and a second CRC masked to the PBCH in a second frame among the 4 frames; and
receiving the control channel based on the determined transmission mode and the determined number of antenna ports.

7. A user equipment (UE) in a wireless communication system, the UE comprising:
-
a wireless communication module configured to receive a signal from an eNode B; and a processor configured to; control the wireless communication module to receive a physical broadcast channel (PBCH) in 4 frames from the eNode B, determine a transmission mode and a number of antenna ports based on a combination of a first cyclic redundancy check (CRC) masked to the PBCH in a first frame among the 4 frames and a second CRC masked to the PBCH in a second frame among the 4 frames, and control the wireless communication module to receive a control channel based on the determined transmission mode and the determined number of antenna ports. - View Dependent Claims (8, 9, 10, 11, 12)
