In the future 5g NR Phase 2 and the following evolution, one base station will support an application scenario with a number greatly increased compared with the number of terminals in the existing system. When the number of terminals is large, grant-free uplink transmission can more embody the advantages of small air interface signaling overhead and high frequency spectrum efficiency. Meanwhile, considering the adoption of a Multi-antenna system in which carrier frequencies become high and Massive (Massive) MIMO (Multi-Input Multi-output), the grant-free transmission scheme in the existing Phase 1 needs to be enhanced.

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 the radio protocol architecture for a User Equipment (UE) and a base station device (gNB or eNB) in three layers: 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 link between the UE and the gNB 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 terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., remote UE, server, etc.).

The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest ). The MAC sublayer 302 provides multiplexing between logical and transport channels.

In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control ) sublayer 306 in layer 3 (L3 layer).
