+The current state of the RAN (`develop` and  `master` branches) and the EPC is available at 
+[OAI Feature Sets](https://gitlab.eurecom.fr/oai/openairinterface5g/-/wikis/OpenAirFeatures/).
+
+# OpenAirInterface Roadmap / Work in progress #  
+
+The main phases are as follows:
+- Phase 1: "noS1" 5G-NR (with pre-configured gNB and OAI UE, no core network)
+- Phase 2: E-UTRA - NR dual connectivity (NSA architecture option 3x, with 4G CN) with COTS UE, **ETA Q2-2020**
+- Phase 3: StandAlone (with 5G CN) with COTS UE, **ETA Q4-2020**
+
+As intermediate steps to reach these goals, we can mention:
+
+- Full DL Transmission (ETA June 2020)
+    - Complete validation of DL-HARQ procedures
+    - Integration with higher layers to inject real traffic
+- Full UL Transmission (ETA July 2020)
+- Further Improvements (ETA Q3-2020)
+    - gNB: replace dummy scheduler with advanced scheduler
+        - support for multiple users, beamforming
+    - PHY: PTRS, multiple DMRS for PDSCH and PUSCH
+    - UE: Completion of random access procedure
+    - Support for Beamforming (mainly FR2)
+        - Multiple SSBs and RACH occasions
+        - RRC config and MAC scheduling of CSI-RS
+        - UE measurements of CSI-RS and feedback reporting
+        - RRC config and MAC handling of TCI states
+    - Support for MIMO
+- for SA Mode (ETA Q4-2020)
+    - RRC
+    - SDAP
+    - N2/N3 interface
