FIELD: radio engineering and communications.
SUBSTANCE: invention relates to wireless communication. Method and an apparatus are provided for transmitting and receiving control information in wireless communication system. eNB generates control information, and transmits control information using at least one enhanced control channel element (eCCE) and at least one antenna port. At least one antenna port is determined according to at least one of a starting index of at least one eCCE and an aggregation level of at least one eCCE.
EFFECT: obtaining mapping between eCCH and reference signals before demodulation.
