Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a data rate higher than that of a 4G communication system, such as LTE, and subsequent communication systems. The present disclosure relates to a method for transmitting a reference signal (RS) in a wireless communication system, comprising the steps of: configuring a transmission resource by including at least one resource block (RB), which does not map the RS, between two RBs, which map the RS, in a first subframe; transmitting a first message for directing an RB offset indicating a gap between the two RBs, which map the RS, and locations of the RBs, which map the RS; and transmitting the RS through the configured transmission resource.

Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system, which is to be provided for supporting a higher data transmission rate after the 4th-generation (4G) communication system, such as long term evolution (LTE). The present invention provides a method for receiving a signal in a multi-carrier system, the method comprising the steps of: performing, with respect to an input signal, a waveform pre-processing operation on the basis of at least one of an equalizing operation and a filtering operation; checking whether the waveform pre-processed signal is a Gaussian proximity signal; and performing soft-de-mapping with respect to the waveform pre-processed signal on the basis of a result of the checking.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Exemplary embodiment of the present invention provide a scheme for reducing feedback overhead when quantizing and feeding back channel state information in a MIMO system. A method for operating a receiver in a MIMO system, according to one embodiment of the present invention, includes the steps of: performing trellis coded quantization for channel information by using a codebook selected from a plurality of codebooks; and transmitting, to a transmitter, feedback information including the quantization result. The step of performing trellis-coded quantization for the channel information includes a step of truncating the channel information and codewords included in the selected codebook into multiple groups of channel vectors and multiple groups of codewords, respectively, and performing trellis-coded quantization for each of the groups of the channel vectors by using each of the groups of the codewords.
