Abstract
A method of operating a wireless communication device (102) configured to communicate with a communications network (100) using frequency duplex transmission in an uplink frequency band (601) and in a downlink frequency band (602) is provided. The method includes monitoring for first downlink reference signals (445, 6052) transmitted by an access node (101) of the communications network (100) in the uplink frequency band (601) and using multiple first downlink transmit beams (351-354); and monitoring for second downlink reference signals (411, 446) transmitted by the access node (101) of the communications network (100) in the downlink frequency band (602) and using multiple second downlink transmit beams (361-364).
