<p>The present invention relates to a control channel transmission method for increasing the capacity of a multi-user control channel in a wireless multi-antenna system. The control channel transmission method according to an embodiment of the present invention includes: a step of excluding resource elements regarding a demodulation reference signal (DM-RS) from each physical resource block pair of each sub-frame in a frequency-first-time-after order and sequentially maps enhanced resource element group (EREG) indexes on resource elements, forming an ECCE by four or eight EREGs from one physical resource block pair or two or more physical resource block pairs, and allocating a down-link control channel located in a data area comprising at least an ECCE; and a step of transmitting the down-link control channel located in the data area to a base station.</p> |
