Abstract: Methods, systems, apparatuses, evolved NodeB (EnBs), User Equipment (UE), and chip sets for all of the same, in cellular communication systems are described. One method for a UE includes receiving a Channel State Information Reference Signal (CSI-RS) transmitted by an eNB according to a pattern in a time-frequency resource grid determined based on the transmission scheme of the eNB, measuring the state of the transmission channel using the CSI-RS, generating channel state information based on the measuring, and transmitting the channel state information as feedback. The UE receives a downlink signal including data and a Cell-specific Reference Signal (CRS) from the eNB and estimates the transmission channel using the CRS and then acquires the data using the estimated channel.

Abstract: Disclosed is a method for transmitting a sounding reference signal (SRS) in a cooperative communication system. The method comprises receiving, from a macro base station, SRS resource information indicating transmission resources of an SRS to be transmitted by a user equipment (UE); transmitting the SRS and uplink data based on a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes the UE-specific SRS subframe configuration information; and transmitting the SRS and the uplink data based on a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the UE-specific SRS subframe configuration information. When a destination of the SRS to be transmitted by the UE is selected as a base station related to the macro base station, the SRS resource information includes the UE-specific SRS subframe configuration information of the base station selected as the destination of the SRS.
