    摘要： 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). A channel information feedback in a wireless communication system and a method of a receiving node of a wireless communication system are provided. The method includes transmitting an indication representing an indexing rule for channel values and block-wise quantized channel information, and receiving beamformed signals mapped to an antenna based on the indexing rule.

    摘要： 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.

    摘要： A method and apparatus for transmitting and receiving a signal using a channel output feedback in a wireless communication system and Hybrid-Automatic Repeat Request (ARQ) are provided. The method and apparatus include a transmitter configured to transmit to a base station and a first packet on a precoder received from the base station. A receiver configured to receive, from the base station, a Channel Output Feedback (COF) of the transmitted first packet and information for transmitting a second packet. A controller configured to prepare a variant of the second packet using the COF and the received information for transmitting the second packet, and to control to transmit the prepared variant to the base station.
