Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 3 shows, in three layers, a radio protocol architecture for a first type of communication node device (UE) and a second type of communication node device (RSU in gNB, eNB or V2X), or between two first type of communication node devices (UE): layer 1, layer 2 and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the links between the first type of communication node device and the second type of communication node device and the two first type of communication node devices (UEs) through PHY301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303 and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which are terminated at the second type of communication node device on the network side.
