Conditional handovers for wireless relay networks
摘要
說明書
Example Embodiment 57: A wireless node that communicates over a radio interface with a wireless access node of a radio access network (RAN) through an Integrated Access and Backhaul (IAB) node, the wireless node comprising: receiver circuitry configured to: receive from the wireless access node 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; receive from the IAB node a notification message comprising information representing a radio condition measured on a path between the IAB node and the wireless access node, and; processor circuitry configured to perform, based on the triggering condition and the information, a handover using the configuration of the candidate target cell.
Example Embodiment 58: The wireless node of Example Embodiment 57, wherein the information corresponds to signal strength/quality, and the handover is performed by evaluating the signal strength/quality and/or the at least one threshold value.
Example Embodiment 59: The wireless node of Example Embodiment 57, wherein the information corresponds to a radio link failure (RLF), and the handover is performed by evaluating a pre-determined value of signal quality/strength and/or the at least one threshold value.
Example Embodiment 60: The wireless node Example Embodiment 57, wherein the triggering condition further comprises an applicability indication indicating whether or not the triggering condition is applicable to the notification message.
