A method for wireless communication by a terminal, a method for wireless communication by a base station, the terminal, and the base station, are provided. The method for wireless communication by the terminal includes receiving first information comprising a muting subframe interval, a subframe offset, and a muting position of a resource element in a resource block, checking presence of a data in a subframe, determining the resource element to be muted in the subframe based on the muting subframe interval, the subframe offset, and the muting position, if the data is present, and receiving the data on a physical downlink shared channel (PDSCH) based on the result of the determining step.

A resource mapping method of a transmitter in a wireless communication system includes precoding pairs of symbols, arranging the pairs of precoded symbols adjacently in a resource block, and transmitting the pairs of precoded symbols in the resource block.
Abstract:
A method of transmitting channel state information. The method includes receiving, from a base station, channel measurement information comprising a plurality of antenna ports to be measured for a serving cell; measuring signals related to the plurality of antenna ports based on the channel measurement information; transmitting reference signal received power (RSRP) information for the plurality of antenna ports based on the measured signals; receiving, from the base station, in response to transmission of the RSRP information, channel state information (CSI) report instruction information for a candidate of a distributed antenna port set including at least one antenna port; measuring a channel state of the at least one antenna port in the candidate; and transmitting the measured channel state to the base station, wherein the candidate of the distributed antenna port set among the plurality of antenna ports is determined based on the RSRP information by the base station.
