Abstract
Embodiments of the present disclosure relate to wireless communication in an IAB network. According to some embodiments of the disclosure, a method may include: ciphering an uplink (UL) packet with a cipher configuration associated with a destination of the UL packet, wherein the UE is connected to a first integrated access and backhaul (IAB) donor and a second IAB donor via an IAB node, and the destination of the UL packet is either the first IAB donor or the second IAB donor; providing the ciphered UL packet with the destination of the UL packet; and transmitting the ciphered UL packet to the destination of the UL packet via the IAB node. By employing the solutions in the present disclosure, a UE can determine that the DL packet is from which IAB donor and thus can process the DL packet accordingly. Moreover, an IAB node can determine that the UL packet is to which IAB donor and can route the UL packet to the corresponding IAB donor.
