Title:
DATA TRANSMISSION METHOD AND DATA TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/165206
Kind Code:
A1
Abstract:
A data transmission method and a data transmission device are disclosed. A method for receiving control data by a terminal can comprise the steps of: demodulating downlink control information (DCI) including an allocation flag and downlink (DL) resource allocation; and demodulating physical downlink shared channel (PDSCH) data by using the DL resource allocation, wherein when the PDSCH data is demodulated on the basis of a demodulation reference signal (DM-RS), the allocation flag indicates information on a reference signal (RS) used for the demodulation of the PDSCH data or information on a PDSCH transmission antenna port.
