Beyond the basic example embodiment and mode mentioned above, FIG. 13 shows further example, optional, non-limiting, basic acts or steps that may be performed by the wireless access node 22-1 of FIG. 11 and FIG. 12. Act 13-1 comprises initiating a handover coordination with another node upon occurrence of a predetermined event. In the example scenario described herein, the other node to be involved in the handover is wireless access node 22-2. The handover coordination of act 13-1 may be performed by handover coordinator 62, which works through a wired backhaul link interface to wireless access node 22-2. The predetermined event may be, for example, receipt of a measurement report from the wireless terminal, e.g., from child node 30, including a measurement regarding a signal received by the wireless terminal from another node, such as wireless access node 22-2. Act 13-2 comprises generating the conditional handover preparation message 40 to include the information facilitating the conditional handover 44. The conditional handover preparation message 40 may be generated, e.g., by message generator 60 of node processor(s) 54-1. Act 13-3 comprises sending or transmitting the conditional handover preparation message to child node 30, e.g., over the wireless backhaul links 34A and 36A and thus via IAB-node 24A.
