Abstract
A communication system is described. The communication system includes 5g base stations (gNodeB) which are communicatively coupled to a user equipment (UE) by a multiple radio access technology (multi-RAT) dual connectivity. A first of the gNodeBs is a master gNodeB which relays control signaling from a 5G network core to a secondary gNodeB. To avoid spectral interference of the control signals between the master gNodeB and the secondary gNodeB, the control signals are transmitted according to a tactical waveform protocol selected from the Department of Defense (DoD) Communication Waveform Inventory (2020), such as a common data link (CDL) protocol.
Claims13
A communication system comprising:
- a fifth generation (5G) core network communicatively coupled to at least one of a secret internet protocol router network (SIPRNet) or a non-classified internet protocol router network (NIPRNet);
- a master 5G base station node (gNodeB) communicatively coupled to the 5G core network by a control plane interface (N2) and a user traffic plane interface (N3);
- a first mobile platform including:
- a secondary gNodeB, wherein the secondary gNodeB is communicatively coupled to the master gNodeB by an Xn control plane (Xn-C) interface and an Xn user plane (Xn-U) interface, wherein at least the Xn-C interface is transmitted according to a protocol selected from the Department of Defense (DoD) Communications Waveform Inventory;
- and
- at least one user equipment (UE), wherein the at least one UE is communicatively coupled to the master gNodeB by a first Uu interface, wherein the at least one UE is communicatively coupled to the secondary gNodeB by a second Uu interface, wherein each of the first Uu interface and the second Uu interface include a control signaling plane and a user traffic plane, wherein the at least one UE is configured to generate an aggregated control signaling plane by aggregating the control signaling plane of the first Uu interface and the second Uu interface by multiple radio access technology (RAT) dual connectivity (MR-DC);
- wherein the protocol is a Bandwidth Efficient Common Data Link (BE-CDL) protocol, wherein the Xn-C interface is transmitted in a band, wherein the band is one of an L band, an S band, a C band, an X band, a Ku band, or a Ka band;
- wherein the band is outside of a 5G new radio frequency range 1 (FR1) of between 450 MHz to 6 GHz;
- wherein the band is outside of a 5G new radio frequency range 2 (FR2) of between 28 GHz to 71 GHz.
