Abstract
An access node in a wireless communication system includes a transceiver configured to receive one or more uplink pilots associated with a user node via a radio link, and a processor configured to determine, based on the one or more uplink pilots, a location of the user node and whether the radio link is a line of sight radio link or a non-line of sight radio link. When the radio link is a line of sight radio link, the processor determines a position based precoding vector based on the location of the user node, and generates a precoded downlink control signal based on the determined position based precoding vector. The transceiver transmits the precoded downlink control signal to the user node.
