Physical Layer The R1 interface adopts Orthogonal Frequency Division Multiplex-
ing (OFDM) at the physical layer.

R6 Interface

R6 interface defines the processing flow between BS and ASN-GW.
The signaling between the BS and the ASN-GW is transmitted
through the R6 tunnel in the format of User Datagram Protocol
(UDP) plus the signaling format defined by NWG stage 3. The me-
dia plane data is borne over the encapsulation tunnel protocol.
UDP bears R6 signaling. Generic Routing Encapsulation (GRE),
Multiple Protocol Label Switching (MPLS) and Virtual Local Area
Network (VLAN) bears R6 data.
The ASN-GW terminates the R6 tunnel from the BS. The R6 tunnel
can adopt various encapsulation technologies, such as GRE, MPLS
and VLAN, and different tunnel granularities are allowed. The R6
data path supports encapsulation protocol and tunnel granularity
negotiation.
