15 Claims

1. A method for transmitting data on a physical shared channel in a wireless communication system, the method performed by a user equipment and comprising:

receiving, from a base station, configuration information including mapping information;

receiving, from the base station, resource allocation information related to a first physical shared channel allocated to transmit the data; and

transmitting, to the base station, the data using the allocated first physical shared channel,

wherein the data is transmitted repeatedly as much as a number of the first physical shared channel on a physical shared channel group including a predetermined number of the first physical shared channels,

wherein a first dedicated demodulation-Reference Signal (DMRS) for the data is mapped to a symbol constructing the physical shared channel group according to the mapping information and transmitted to the base station,

wherein the mapping information is information regarding mapping a second DMRS for a second physical shared channel including symbols of a same number as a symbol number constructing the physical shared channel group, and

wherein the second DMRS is transmitted only for the second physical shared channel related to a configured redundancy version (RV), and the second physical shared channel not related to the configured RV shares the first DMRS with the first physical shared channel.
