摘要
UE positioning is added by use of a reconfigurable reflecting surface (e.g., IRS). The IRS is configured to adjust elements of the surface. The configuration may include signal switching on or off, signal phase, group delay, or signal amplitude. Positioning reference signal transmissions are performed that have line of sight to the UE and that reflect off the IRS. The UE takes measurements for the transmissions and can determine measurement(s) of angle of arrival or time of arrival or reference signal received power, and/or determine a channel estimation. Multiple methods are proposed to provide UE positioning.
