Abstract: An inter-cell cooperative transmission-based transmission and reception method is provided. According to an exemplary embodiment, the inter-cell cooperative transmission-based transmission and reception method includes acquiring data of a terminal from a macro base station without exchanging data between small base stations in an environment where an exchange of cooperation-related information between the small base stations or between the small base stations and the terminal is limited; and transmitting the control information and the data, which are acquired by the small base stations, to the terminal in a cooperative manner among the base stations.

Abstract: Disclosed are operation methods of communication nodes supporting superposition transmission in a cellular communication system. An operation method of a base station comprises dividing a transmission block used for communications in the communication system into a plurality of sub transmission blocks each of which includes at least one resource block; setting transmit power allocation coefficients respectively for the plurality of sub transmission blocks; and transmitting the transmission block to which a superimposed signal is mapped, the superimposed signal including information indicating a number of resource blocks included in each of the plurality of sub transmission blocks, information indicating the transmit power allocation coefficients, first data units for the first terminal, and second data units for the second terminal. The first data units and the second data units are mapped to a same resource in the transmission block.
