Method for establishing uplink data channel on basis of shared demodulation reference signal, and device therefor

Abstract:

Provided are an sTTI setting method for an sPUSCH in a short ITT frame structure and a specific operating method for an sPUSCH based on a shared DM-RS. In the method, a shared DM-RS within an SPUSCH is allocated only to a specific symbol included in a partial sTTI and is used in all sPUSCHs within a legacy TTI (=1 ms).
