@@ -36,13 +36,24 @@ The following features are valid for the gNB and the 5G-NR UE.
* Encoder and decoder for short blocks
* Support for UL transform precoding (SC-FDMA)
Furthermore, the gNB and UE support
These modes of operation are supported:
* "noS1" mode (DL and UL):
* "phy-test" mode (gNB, nrUE):
- gNB and nrUE have hardcoded RNTI and radio configuration
- gNB schedules the nrUE all the time, even if no UE connected
- can be used for performance evaluation
* "noS1" mode (DL and UL, gNB, nrUE):
- Connection setup stops after RA; RRC configuration is exchanged through
files
- Creates TUN interface to PDCP to inject and receive user-place traffic
- No connection to the core network
* Standalone (SA) mode:
- UE can register with the 5G Core Network through the gNB, establish a PDU Session and exchange user-plane traffic
* Standalone (SA) mode (gNB, nrUE):
- UE can register with the 5G Core Network through the gNB, establish a PDU
Session and exchange user-plane traffic
- Reestablishment supported
* Non-standalone (NSA) mode (gNB):
- UE can use the gNB for user plane traffic while connected to the 4G eNB
- is unstable (only one UE connection)
