Abstract: An apparatus is configured to perform a method for providing a wireless communication service to at least one User Equipment (UE) from among a plurality of UEs having links established with a distributed small Base Station (BS) in a Virtual Cell Network (VCN) system in which a plurality of virtual cells exist within one macro cell. The method includes selecting at least one UE to which a wireless communication service is to be provided in a virtual cell, calculating a feedback allocation amount for each of the selected at least one UE, by sharing path losses and user characteristics measured and determined on a UE basis by each of the plurality of virtual cells, and providing information about the calculated feedback allocation amount to the selected at least one UE.

Abstract: Disclosed are a multi-antenna system and a transmission and method based on index coding and beamforming thereof. A transmitter including a plurality of antennas may be configured to classify a plurality of receivers into at least one group, determine an index code for the group, design a beamforming matrix for the group, and transmit at least one of a plurality of files to the group through the antennas based on the index code and the beamforming matrix.
