Patent attributes
An integrated access backhaul (IAB) node with an unknown position may use the mobile terminated (MT) function to send or receive reference signals to or from multiple base stations in one or more positioning sessions for positioning of the IAB node. The distributed unit (DU) function may be used additionally, or alternatively, to send or receive reference signals to or from multiple nodes, e.g., user equipments (UEs) or MT functions of downstream IAB nodes. Positioning measurements from the reference signals may be sent to a location server, which may determine the position of the IAB node. The location server may further receive an indication of the mobility of the IAB node, which may be used for positioning of UEs, e.g., by excluding information about a mobile IAB node during positioning.
