Abstract
A method of monitoring search space of enhanced downlink control channel (EPDCCH) for a user equipment in an orthogonal frequency-division multiple access (OFDMA) system includes determining whether to blind decode a monitoring downlink control information (DCI) candidate in a search space of a EPDCCH according to a code rate of the monitoring DCI decoding candidate, wherein the search space is determined according to a fixed threshold associated to a number of available resource element in a physical resource block pair for the EPDCCH.
