  • Reporting of Coefficients for Channel State Information
    Publication number: 20220052734
    Abstract: A method performed by a wireless device (510, 800, 1200) for reporting channel state information (CSI) for a downlink channel is disclosed. The method comprises transmitting (601, 705) a CSI report for the downlink channel to a network node (560, 1100), the CSI report comprising: a set of reported coefficients; an indication of how the network node is to interpret the set of reported coefficients; and an indication of a payload size of the set of the reported coefficients.

  • TRANSMISSION OF REFERENCE SIGNALS FROM A TERMINAL DEVICE
    Publication number: 20210359805
    Abstract: There is provided mechanisms for transmission of reference signals. A method is performed by a terminal device. The terminal device comprises at least two physical antenna ports. The method comprises obtaining channel information. The method comprises determining, for at least one given precoder in a codebook, an uplink reference signal to physical antenna port mapping based on the channel information. The method comprises transmitting uplink reference signals in the physical antenna ports according to the determined mapping.

  • Transmission of reference signals from a terminal device
    Patent number: 11012129
    Abstract: There is provided mechanisms for transmission of reference signals. A method is performed by a terminal device. The terminal device comprises at least two physical antenna ports. Each physical antenna port is fed by its own power amplifier. The method comprises transmitting, in only the physical antenna port is fed by the power amplifier configured for highest total output power of all the power amplifiers, as many uplink reference signals as there are physical antenna ports in total.
