The present disclosure provides a method implemented in a wireless communication device for determining an Angle of Arrival (AOA) of a wireless signal received at the wireless communication device. The method comprises estimating the AOA of the wireless signal, determining that the estimated AOA is ambiguous and acquiring signal strength measurements for the wireless signal received at two other wireless communication devices, which are located substantively symmetrically about a normal of the wireless communication device's antenna array. The method further comprises disambiguating the estimated AOA based on a comparison of the acquired signal strength measurements. The present disclosure also provides the wireless communication device as well as a Radio Base Station (RBS) comprising the wireless communication device.
