Title: PROCESSING UPLINK SIGNALS IN HIGH SPEED SCENARIO
Abstract:
A network node is connected to a plurality of antenna nodes that are located along a path where a plurality of wireless communication devices are located. The antenna nodes are controlled (302) to maintain reception radio lobes substantially along the path such that the wireless communication devices can communicate with the network node via the reception radio lobes. From a detected (304) radio frequency signal, a determination (306) is made that a UE belongs to a group of UEs having common Doppler radio frequency characteristics. This determination then enables processing (308) of the received signal involving the common Doppler characteristics.
