Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: Examples provide a mobile communication system, a mobile device, user equipment, a network node, a NodeB, circuits, apparatuses, methods, machine readable media and computer programs for mobile device, user equipment, network nodes, NodeBs. An apparatus (10) for a user equipment, UE (100), configured to communicate in a mobile communication system (400) comprises one or more interfaces (12) configured to communicate within the mobile communication system (400). The apparatus (10) comprises a control module (14) configured to control the one or more interfaces (12). Then control module (14) is configured to process reference signal configuration information received by the one or more interfaces (12). The reference signal configuration information comprises information on a reference signal radio configuration information resource, the reference signal radio resource specifying at least one reference signal from a group of two or more reference signals. The two or more reference signals differ in at least one element of the group of a time-frequency resource, a sequence, and a cyclic shift. The control module (14) is configured to enable measurements based on the at least one reference signal.
