ABSTRACT:
A method for determining direction of transmission using an antenna array having a number of panels is disclosed. Each panel is configured to receive signals. According to one aspect of the method, each of the panels is directed to receive signals from a transmitting node. For each panel, a first table having data representing received signal power difference between the panel and a first neighboring panel and a second table having data representing received signal power difference between the panel and a second neighboring panel are built. The panel with the maximum received power is identified. For the identified panel, a first gain table and a second gain table corresponding to its first and second neighboring panels are searched to identify a first transmission angle and a second transmission angle, if any. A transmission angle relative to the transmitting node is determined using the first and second transmission angles.
