  • Publication number: 20190123870
    Abstract: 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.

  • Patent number: 10271309
    Abstract: Systems and methods are disclosed for transmission and reception of an uplink grant during a gap created in radio resources assigned by a previous multiple Transmit Time Interval (multi-TTI) uplink grant in a system operating according to a Time Division Duplexing (TDD) scheme. In one embodiment, a method of operation of a radio network node in a cellular communications network is provided. The method includes transmitting a first uplink grant that assigns radio resources for a multi-TTI uplink transmission, and transmitting a second uplink grant during a gap in the radio resources assigned by the first uplink grant. In one embodiment, by utilizing the gap to transmit the second uplink grant, uplink radio resources assigned for uplink transmission can be maximized, which is particularly beneficial in high uplink traffic conditions.
