As further shown in FIG. 28, node processor(s) 54 of wireless access node 22(27) may comprise message generator 60(27) and path activation controller 162(27). The message generator 60(27) serves to generate, e.g., one or more reconfiguration message(s) 200, shown as reconfiguration message 200 in FIG. 27. The reconfiguration message 200 serves to activate a first data path 202 and a second data path 204. As shown in FIG. 27, the first data path 202 is established between the wireless access node 22(27) and the wireless node 30(27); the second data path 204 is relayed by the wireless relay node 24(27). The message generator 60(27) may generate radio resource control, RRC, messages, such as a RRCReconfiguration message, and therefore may be included in or comprise an RRC entity of wireless access node 22(27).
