Page 4: Overview
Kumu Self Backhaul UE Relay User Guide v1.1 1 Overview The document describes the product requirements for a Full Duplex UE Relay based on Kumu Networks’ cancellation module. The product is designed to be paired with an external eNB, and backhaul the eNB data to the nearest macro base station using the same access frequencies used by the eNB (and the macro network). -
Page 5: Product Architecture
Kumu Self Backhaul UE Relay User Guide v1.1 2.2 Product Architecture Conceptually an LTE self-backhaul Relay is an eNodeB with its Ethernet connection connected to a well provisioned cellphone that talks to a base station. In the case of the Kumu Relay product the EnodeB is external vendor equipment. - Page 6 Kumu Self Backhaul UE Relay User Guide v1.1 Figure 3 Relay control plane block diagram To summarize, the UE Relay connects to the eNB via Ethernet port, for data transport, and via the antenna port, to enable self-interface cancellation for full-duplex operation. The UE Relay provides backhaul connectivity for the eNB in the form of LTE that transports the data through the operator commercial wireless network.

Page 8: Connectivity To Management
Kumu Self Backhaul UE Relay User Guide v1.1 2.5 Connectivity to Management There are two options for connectivity of management/monitoring for the Kumu relay backhaul: 1) Provide out of band backhaul. The secondary Ethernet connection provides this functionality when connected to a microwave or other similar link 2) Use the in-band backhaul over the UE connection. -
Page 9: Physical Ethernet Connectivity
Kumu Self Backhaul UE Relay User Guide v1.1 2.5.2 Physical Ethernet Connectivity The UE Relay exposes two Ethernet ports – one for local configuration/bring-up and the other for connectivity to the small cell. Each interface is pre-allocated an IP address that can be reprogrammed through the management interface. -
