Title: A RADIO NETWORK NODE, A WIRELESS DEVICE AND METHODS THEREIN FOR REFERENCE SIGNAL CONFIGURATION
Abstract:
A Radio Network Node (RNN) 210 and a method therein for configuration of Demodulation Reference Signals (DMRSs) of a wireless device 208. The RNN 210 and the wireless device 208 are operating in a wireless communications network 200. The RNN indicates a DMRS configuration to the wireless device, which DMRS configuration is dynamically configurable to relate to one or more out of a first Orthogonal Frequency- Division Multiplexing (OFDM) symbol comprising DMRSs for a first transmission; and a second OFDM symbol comprising DMRSs for the first transmission.
