    摘要： Disclosed in one embodiment is a downlink control channel decoding method of a wireless communication system, comprising the steps of: receiving setting information on a first resource and a second resource; blind-decoding reception signals on PDCCH resource candidates within the first resource determined by the setting information, so as to search for a PDCCH of the first resource; and blind-decoding reception signals on PDCCH resource candidates within the second resource determined by the setting information, and by blind-decoding, among the resource candidates, the remaining one or more resource candidates excluding one or more resource candidates, which include a resource area overlapping with the PDCCH having been searched for, so as to search for a PDCCH of the second resource. Therefore, since the number of PDCCH resource candidates required for blind-decoding is adjusted on the basis of an overlapping resource area, power consumption of a terminal can be reduced.

    摘要： The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. To this end, a base station using a large-scale antenna transmits, to a terminal, reference signal resource configuration information including multiple pieces of reference signal configuration information and reference signal port information, for transmission of a reference signal, and transmits the reference signal to the terminal using some or all of channel measurement resources indicated by the multiple pieces of reference signal configuration information and the reference signal port information included in the reference signal resource configuration information. In this case, the channel measurement resources may correspond to antenna ports, the number of which is indicated by a combination of the multiple pieces of reference signal configuration information and the reference signal port information.

    摘要： Disclosed is a communication scheme and a system therefor, the communication scheme for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system. The present disclosure can be applied to intelligent services (such as smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security, and safety related services) on the basis of 5G communication technology and IoT related technology. A method of receiving channel feedback information by an evolved node B (eNB) in a communication system using multiple antennas, provided in an embodiment of the present disclosure, includes generating reference signal configuration information comprising power boosting information associated with reference signals; transmitting the reference signal configuration information to a user equipment (UE); and receiving channel feedback information on a channel state estimated based on the reference signal configuration information from the UE.
