Abstract: The present disclosure pertains to a method and an apparatus for generating a reference signal (RS) sequence and a data scrambling sequence. A method for a base station transmitting a reference signal according to an embodiment of the present disclosure may comprise the steps of: generating a reference signal sequence; and transmitting a reference signal corresponding to the generated reference signal sequence. The reference signal sequence can be generated using an initial sequence that is determined using a slot number in a transmission frame, a symbol number in a slot, and a scrambling identifier (ID).

Abstract: Disclosed are: a communication technique for merging, with the Internet of Things (IoT) technology, a 5th-generation (5G) communication system for supporting a data transmission rate higher than that of a 4th-generation (4G) system; and a system therefor. The disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retailing, security and safety related services) on the basis of 5G communication technology and IoT related technology. One embodiment of the present invention enables a terminal to receive at least one reference signal from a base station in a mobile communication system, and to generate channel state information on the basis of the at least one reference signal so as to transmit the channel state information to the base station, wherein the at least one reference signal is received in a downlink pilot time slot (DwPTS) by using a resource determined on the basis of a special subframe configuration.

Abstract: 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.
