     Embodiment 3 
     Embodiment 3 illustrates a schematic diagram of a radio protocol architecture of a user plane and a control plane according to the present disclosure, as shown in  FIG. 3 .  FIG. 3  is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane  350  and a control plane  300 . In  FIG. 3 , the radio protocol architecture for a control plane  300  between a first communication node (UE, gNB or, RSU in V2X) and a second communication node (gNB, UE, or RSU in V2X), or between two UEs, is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer which performs signal processing functions of various PHY layers. The L1 is called PHY  301  in the present disclosure. The layer 2 (L2)  305  is above the PHY  301 , and is in charge of the link between the first communication node and the second communication node or between two UEs via the PHY  301 . The L2  305  comprises a Medium Access Control (MAC) sublayer  302 , a Radio Link Control (RLC) sublayer  303  and a Packet Data Convergence Protocol (PDCP) sublayer  304 . All the three sublayers terminate at the second communication nodes of the network side. The PDCP sublayer  304  provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer  304  provides security by encrypting a packet and provides support for handover of a first communication node between second communication nodes. The RLC sublayer  303  provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer  302  provides multiplexing between a logical channel and a transport channel. The MAC sublayer  302  is also responsible for allocating between first communication nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer  302  is also in charge of HARQ operation. In the control plane  300 , The RRC sublayer  306  in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second communication node and the first communication node. The radio protocol architecture in the user plane  350  comprises the L1 layer and the L2 layer. In the user plane  350 , the radio protocol architecture used for the first communication node and the second communication node in a PHY layer  351 , a PDCP sublayer  354  of the L2 layer  355 , an RLC sublayer  353  of the L2 layer  355  and a MAC sublayer  352  of the L2 layer  355  is almost the same as the radio protocol architecture used for corresponding layers and sublayers in the control plane  300 , but the PDCP sublayer  354  also provides header compression used for higher-layer packet to reduce radio transmission overhead. The L2 layer  355  in the user plane  350  also comprises a Service Data Adaptation Protocol (SDAP) sublayer  356 , which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversified traffics. Although not described in  FIG. 3 , the first communication node may comprise several higher layers above the L2  355 , such as a network layer (i.e., IP layer) terminated at a P-GW  213  of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.).

In the transmission from the first communication device  410  to the second communication device  450 , the controller/processor  475  provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation of the second communication device  450  based on various priorities. The controller/processor  475  is also in charge of a retransmission of a lost packet and a signaling to the second communication device  450 . The transmitting processor  416  and the multi-antenna transmitting processor  471  perform various signal processing functions used for the L1 layer (i.e., PHY). The transmitting processor  416  performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device  450  side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor  471  performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals to generate one or more spatial streams. The transmitting processor  416  then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor  471  performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter  418  converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor  471  into a radio frequency (RF) stream, which is later provided to different antennas  420 . 
     In a transmission from the first communication device  410  to the second communication device  450 , at the second communication device  450 , each receiver  454  receives a signal via a corresponding antenna  452 . Each receiver  454  recovers information modulated to the RF carrier, and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor  456 . The receiving processor  456  and the multi-antenna receiving processor  458  perform signal processing functions of the L1 layer. The multi-antenna receiving processor  458  performs reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver  454 . The receiving processor  456  converts the processed baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor  456 , wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor  458  to recover any second communication device  450 -targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor  456  to generate a soft decision. Then the receiving processor  456  decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted by the first communication device  410  on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor  459 . The controller/processor  459  provides functions of the L2 layer. The controller/processor  459  can be associated with a memory  460  that stores program code and data. The memory  460  can be called a computer readable medium. In the transmission from the first communication device  410  to the second communication device  450 , the controller/processor  459  provides demultiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer. Or various control signals can be provided to the L3 for processing. 
     In a transmission from the second communication device  450  to the first communication device  410 , at the second communication device  450 , the data source  467  is configured to provide a higher-layer packet to the controller/processor  459 . The data source  467  represents all protocol layers above the L2 layer. Similar to a transmitting function of the first communication device  410  described in the transmission from the first communication node  410  to the second communication node  450 , the controller/processor  459  performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the first communication device  410  so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor  459  is also responsible for a retransmission of a lost packet, and a signaling to the first communication device  410 . The transmitting processor  468  performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor  457  performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor  468  then modulates generated spatial streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor  457 , are provided from the transmitter  454  to each antenna  452 . Each transmitter  454  first converts a baseband symbol stream provided by the multi-antenna transmitting processor  457  into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna  452 . 
     In a transmission from the second communication device  450  to the first communication device  410 , the function of the first communication device  410  is similar to the receiving function of the second communication device  450  described in the transmission from the first communication device  410  to the second communication device  450 . Each receiver  418  receives a radio frequency signal via a corresponding antenna  420 , converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor  472  and the receiving processor  470 . The receiving processor  470  and the multi-antenna receiving processor  472  jointly provide functions of the L1 layer. The controller/processor  475  provides functions of the L2 layer. The controller/processor  475  can be associated with the memory  476  that stores program code and data. The memory  476  can be called a computer readable medium. In the transmission between the second communication device  450  and the first communication device  410 , the controller/processor  475  provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the second communication device (UE)  450 . The higher-layer packet coming from the controller/processor  475  may be provided to the core network.
