A relay node (34) which wirelessly communicates on a backhaul link over a first interface with a base station node (28) of a radio access technology network and which wirelessly communicates on an access link over a second interface with a wireless terminal (30). The relay node (34) comprises a transceiver (36) and a duplexer section (40). The transceiver (36) comprises a transmitter (42) and a receiver (44). The duplexer section (40) comprises plural transceiver ports (50, 52) and at least one antenna port (48). The relay node (34) is configured to provide a transmit signal from the transmitter (42) in a manner whereby a backhaul link portion of the transmit signal is conveyed through a different transceiver port (50) of the duplexer section than is an access link portion of the transmit signal.
