Abstract:
Systems and methods for wireless communications with control and user plane separation includes radio units. The radio units include a central unit (CU) which includes a central unit user plane (CU-UP) located in at least one of the radio units. The central unit user plane (CU-UP) includes a first Packet Data Convergence Protocol (PDCP) layer and a Service Data Adaptation Protocol (SDAP) layer connected to the first Packet Data Convergence Protocol (PDCP) layer. The central unit (CU) also includes a central unit control plane (CU-CP) located remotely from the central unit user plane (CU-UP). The central unit control plane (CU-CP) includes a second Packet Data Convergence Protocol (PDCP) layer and a Radio Resource Control (RRC) layer connected to the second Packet Data Convergence Protocol (PDCP) layer. The central unit user plane (CU-UP) and the central unit control plane (CU-CP) are virtualized and shared by the radio units.

Claim (Index 18):
A virtualized radio base station node, comprising:\n a plurality of radio units comprising: a remote radio head including a lower physical layer (PHY-Low), an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), MIMO antenna arrays, and a radio frequency (RF) transceiver; a distributed unit connected to the remote radio head, the distributed unit including a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a higher physical (PHY-high) layer; and a central unit (CU) connected to the distributed unit, the central unit comprising a central unit user plane (CU-UP) and a central unit control plane (CU-CP), wherein the central unit user plane (CU-UP) includes a first Packet Data Convergence Protocol (PDCP) layer and a Service Data Adaptation Protocol (SDAP) layer, and wherein the central unit control plane (CU-CP) includes a second Packet Data Convergence Protocol (PDCP) layer and a Radio Resource Control (RRC) layer, wherein the remote radio head (RRH), the distributed unit (DU), and the central unit user plane (CU-UP) are located in at least one of the radio units, and wherein the central unit control plane (CU-CP) is physically separated from the central unit user plane (CU-UP) and is located remotely from the central unit user plane (CU-CP), and wherein the central unit user plane (CU-UP) and the central unit control plane (CU-CP) communicate with each other via an interface protocol, and wherein the remote radio head, the distributed unit and the central unit are virtualized and shared by the plurality of radio units.
