Methods and systems for providing channel estimation
Embodiments herein relate to a method performed by a radio-network node (110) for handling Beam Reference Signals, BRS, of a beam transmitted by the radio-network node (110) in a wireless communications network. The radio-network node creates BRS blocks, wherein each BRS block comprises a respective group of adjacent subcarriers for the BRS belonging to a port of the beam, wherein the BRS belonging to the port is carried over each subcarrier in the respective group of adjacent subcarriers of each BRS block. Furthermore, the radio-network node transmits the BRS blocks spread over a bandwidth in a same Orthogonal Frequency Division Multiplexing, OFDM, symbol.
