Conditional handovers for wireless relay networks
摘要
說明書
In one example, a wireless access node of a radio access network (RAN) that communicates over a radio interface with a wireless node through an Integrated Access and Backhaul (IAB) node, the wireless access node comprising: processor circuitry configured to generate a reconfiguration message comprising a conditional handover configuration, the conditional handover configuration comprising a triggering condition and a configuration of a candidate target cell, the triggering condition comprising at least one threshold value; transmitter circuitry configured to transmit the reconfiguration message to the wireless node; wherein the triggering condition and information are used by the wireless node to perform a handover using the configuration of the candidate target cell, the information representing a radio condition measured on a path between the IAB node and the wireless access node, and; the information is included in a notification message sent to the wireless node by the IAB node.
