Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for a first type of communication node device (UE) and a second type of communication node device (gNB, eNB or RSU in V2X), or between two first type of communication node devices (UE) 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 PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for 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 PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second type of communication node device on the network side. Although not shown, the first type of communication node device may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., far end UE, server, etc.).

The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handoff support between communication node devices of the second type to communication node devices of the first type. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the first type of communication node devices. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the first type of communication node device and the second type of communication node device is substantially the same for the physical layer 301 and the L2 layer 305, but without header compression functionality for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e. radio bearers) and for configuring the lower layers using RRC signaling between the second type of communication node device and the first type of communication node device.

A data source 567 provides upper layer packets, which may include data or control information such as SL-SCH, to a controller/processor 590, the controller/processor 590 providing packet header compression decompression, encryption and decryption, packet segmentation concatenation and reordering, and multiplexing and demultiplexing between logical and transport channels to implement the L2 layer protocol. Transmit processor 555 performs various signal transmit processing functions for the L1 layer (i.e., the physical layer) including coding, interleaving, scrambling, modulation, power control/allocation, precoding, and physical layer control signaling generation, among others. Receive processor 552 performs various signal receive processing functions for the L1 layer (i.e., the physical layer) including decoding, deinterleaving, descrambling, demodulation, depredialing, physical layer control signaling extraction, and the like. The transmitter 556 is configured to convert the baseband signal provided by the transmission processor 555 into a radio frequency signal and transmit the radio frequency signal via the antenna 560, and the receiver 556 is configured to convert the radio frequency signal received by the antenna 560 into a baseband signal and provide the baseband signal to the reception processor 552. The composition in the second type of communication node device (500) is the same as the corresponding in the first type of communication node device 550.
In SL (Sidelink), upper layer packets (such as the information carried by the first signaling, the information carried by the first wireless signal, and the third information in this application) are provided to a controller/processor 540, and the controller/processor 540 implements the functions of the L2 layer.

The controller/processor 540 is also responsible for HARQ operations (if supported), repeated transmissions, and signaling to the first type of communication node device 550. Transmit processor 515 performs various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control/allocation, precoding, and physical layer control signaling generation, etc., where the generation of the physical layer signals for the first signaling, the first radio signal, and the third information is done at transmit processor 515, the modulation symbols are split into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and/or multi-carrier symbol, and then transmitted as a radio frequency signal by transmit processor 515 mapped to antenna 520 via transmitter 516. At the receiving end, each receiver 556 receives a radio frequency signal through its respective antenna 560, each receiver 556 recovers baseband information modulated onto a radio frequency carrier, and provides the baseband information to a receive processor 552. The receive processor 552 performs various signal receive processing functions of the L1 layer. The signal reception processing functions include, among others in this application, reception of physical layer signals of the first signaling, the first radio signal, and the third information, demodulation based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)) by means of multicarrier symbols in a multicarrier symbol stream, followed by descrambling, decoding, deinterleaving to recover data or control transmitted by the second type communication node apparatus 500 on a physical channel, followed by providing the data and control signals to the controller/processor 590.
