CHANNEL SOUNDING USING MULTIPLE ANTENNA PANELS

Abstract:

A method of operating a wireless communication device (102) includes generating (1001) a reference signal sequence (150) based on a base signal sequence and a shift signal sequence selected from a plurality of candidate shift signal sequences transmitting (1002) the reference signal sequence (150) via an antenna port (5031-5033) of a plurality of antenna ports (5031-5033) of the wireless communication device (102) and via an antenna panel (5023, 5024) of a plurality of antenna panels (5023, 5024) of the wireless communication device (102). The shift signal sequence is selected from the plurality of candidate shift signal sequences depending on the antenna panel (5023, 5024) used for transmitting the reference signal sequence (150).
