Title: METHOD FOR TRANSMITTING UPLINK SIGNAL IN DISTRIBUTED ANTENNA COMMUNICATION SYSTEM AND DEVICE FOR SAME
Abstract:
Disclosed is a method for a terminal, which comprises a plurality of distributed antenna units, transmitting an uplink signal comprising a plurality of codewords in a wireless communication system. More particularly, the method comprises the steps of: receiving, from a base station, control information for an uplink signal; mapping a plurality of codewords to a plurality of layers in accordance with an indicator comprised in the control information; precoding the layer-mapped codewords; and transmitting the uplink signal comprising the precoded codewords to the base station, wherein the indicator indicates one of the two or more codeword-to-layer mapping rules corresponding to the number of the layers.
