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: Disclosed is a method and an apparatus for transmitting and receiving data via a MAC protocol in a mobile communication system. The method includes inputting at least one Service Data Unit (SDU) containing transmission data through a corresponding logical channel and generating at least one first Protocol Data Unit (PDU) that includes said at least one SDU without including multiplexing information for identification of the logical channel, by a first transmission entity; acquiring the first PDU and generating a second PDU including the first PDU in a payload of the second PDU, by a second transmission entity that operates between the first transmission entity and a physical layer; inserting the multiplexing information for identification of the logical channel corresponding to said at least one first PDU into header information of the second PDU; and transmitting the second PDU through the physical layer. The method can reduce load due to additional processing, such as a bit operation or memory copying, in a receiver requiring high speed data transmission.

Abstract: A method is provided for when an allocation area of data indicated by control information overlaps a subsequent control information area occurring after a control information area is pre-configured by a higher layer signal or system information. A terminal may omit or partially perform a blind search for the subsequent control information area overlapping a data area. Additionally, a terminal may receive data based on an assumption that a data area has been mapped to the subsequent control information area, or a terminal may receive data based on an assumption that a data area has not been mapped to the subsequent control information area. Thus, the terminal may adaptively adjust a configuration area for a data area and prevent blind decoding to further reduce power consumption.

Abstract: A method, provided by the present disclosure, of transmitting a reference signal by means of a base station in a wireless communication system using a plurality of antenna ports comprises the steps of: mapping wireless resources, for transmitting a reference signal, to a plurality of antenna ports for transmitting the reference signal; and using the wireless resources and transmitting the reference signal to a terminal through the mapped antenna ports. The step of mapping to the antenna ports is characterized by being executed on the basis of a combination of a first mapping pattern between the wireless resources and the antenna ports and a second mapping pattern between the wireless resources and the antenna ports.
