Title: SIGNALING OF DEMODULATION REFERENCE SIGNAL CONFIGURATION FOR UPLINK SHORT TTI TRANSMISSIONS
Abstract:
A method, wireless device and network node for multiplexing demodulation reference signals, DMRS, during short transmission time intervals, sTTIs. According to one aspect, a method includes generating an indication of an interleaved frequency division multiple access, IFDMA, subcarrier configuration for DMRS transmission. The method further includes transmitting to the wireless device (16) the indication of IFDMA subcarrier configuration.
