This invention provides an arrangement and method for estimating network traffic based on angle of arrival determination in a cellular network, in which the cell is served by a base station and the base station transmits RF signals to a plurality of user equipments (UEs) via a downlink channel and receives RF signals from a plurality of UEs via an uplink channel within the cell. The arrangement comprises an antenna array, a downlink receiving antenna, a combiner and an angle processing unit (APU) that is communicatively linked to the base station. The angle processing unit determines the angle of arrival (AoA) of signals from user equipments by monitoring the usage of the frequency band. The method for determining AoA includes: selecting a specific time slot from the downlink signals; calculating the received signal strength indication (RSSI) values for each of the resource blocks (RBs) at the specific time slot from the uplink signals; delivering the RSSI values of all the antennas to the angle processing unit (APU); and determining AoA by monitoring RSSI values. |
