  • Method and arrangement for positioning in a wireless communications system
    Patent number: 10212686
    Abstract: Systems and methods provide for an increase in hearability by a user equipment (UE, 116). This increase in hearability can be used to improve positioning results. Two different types of positioning subframes can be transmitted by cells in a radio access network (RAN) to improve hearability: measurement subframes and low-interference subframes. The selection of which type of positioning subframe to transmit can be determined algorithmically by the transmitting entity.
