Method of configuring resource blocks for search space of distributed downlink control channel in wireless communication system and apparatus thereof

PURPOSE: A method for composing a resource block for the searching area of a distributive type downlink control channel and a device thereof are provided to efficiently compose the resource block for the search area of the distributive type downlink control channel. CONSTITUTION: An enhanced resource element groups (EREG) of a first number are defined for each of resources blocks for an enhanced physical downlink control channel (EPDCCH). The EPDCCH is received by monitoring EPDCCH candidates composed of one or more enhanced control channel elements (ECCE) in the resource blocks. At least one of ECCE is composed of EREGs of a second number included in different resource blocks. The indices of the resource block including the EREG of the second number is determined based on a certain value of dividing the number of the resource blocks by the second number. [Reference numerals] (AA) PRB pair #0; (BB) PRB pair #1; (CC) PRB pair #p; (DD) Suppose n=p^*P+1 and suppose that [n/P] is p; (EE) PRB pair #q (=p+[N/K])
