Figure 3 Figure 3 is a schematic diagram illustrating one embodiment of a radio protocol architecture for user plane 350 and control plane 300, and Figure 3 shows the radio protocol architecture of control plane 300 between a first communication node device (UE, gNB, or RSU in V2X) and a second communication node device (gNB, UE, or RSU in V2X), or between two UEs using three layers, namely 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 is referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the links between the first communication node device and the second communication node device, and between the two UEs via PHY 301. The L2 layer 305 includes the MAC (Media Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which are terminated at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides handover support between the first communication node device and the second communication node device. The RLC sublayer 303 compensates for out-of-order reception due to HARQ by providing splitting and reconstruction of upper-layer data packets, retransmission of lost data packets, and reordering of data packets. The MAC sublayer 302 provides multiplexing between logical channels and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a single cell between the first communication node devices. The MAC sublayer 302 is also responsible for HARQ operation. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second communication node device and the first communication node device.The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer).

[0234] Embodiment 4 Embodiment 4, as shown in Figure 4, shows schematic diagrams of the first and second communication devices according to this application. Figure 4 is a block diagram of the first communication device 410 and the second communication device 450 communicating with each other within an access network.

[0235] The first communication device 410 comprises a controller / processor 475, memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitting / receiving device 418, and an antenna 420.

[0236] The second communication device 450 comprises a controller / processor 459, memory 460, data source 467, transmit processor 468, receive processor 456, multi-antenna transmit processor 457, multi-antenna receive processor 458, transmit / receive device 454, and antenna 452.

[0237] In transmission from the first communication device 410 to the second communication device 450, the first communication device 410 provides upper-layer data packets from the core network to the controller / processor 475. The controller / processor 475 implements L2 layer functions. In transmission from the first communication device 410 to the first communication device 450, the controller / processor 475 provides the second communication device 450 with header compression, encryption, packet splitting and reordering, multiplexing between logical channels and transport channels, and radio resource allocation based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) in the second communication device 450, as well as mapping of signal clusters based on various modulation schemes (e.g., two-phase-shifted modulation (BPSK), four-phase-shifted modulation (QPSK), M-phase-shifted modulation (M-PSK), and M-quadrature-amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing, on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes them with a reference signal in the time domain and / or frequency domain (e.g., a pilot frequency), and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel that carries the time-domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream.Each transmitting device 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency stream, which is then provided to different antennas 420.

[0238] In transmission from the first communication device 410 to the second communication device 450, each receiving device 454 in the second communication device 450 receives the signal via its corresponding antenna 452. Each receiving device 454 reconstructs the information modulated on the radio frequency carrier, converts the radio frequency stream into a baseband multicarrier symbol stream, and provides the baseband multicarrier symbol stream to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receive analog precoding / beamforming operation on the baseband multicarrier symbol stream from the receiving device 454. The receiving processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream from the time domain to the frequency domain after the receive analog precoding / beamforming operation. In the frequency domain, the physical layer data signal and reference signal are demultiplexed by the receiving processor 456. The reference signal is used for channel estimation, and the data signal is reconstructed after multi-antenna detection in the multi-antenna receiving processor 458 to reconstruct an arbitrary spatial stream destined for the second communication device 450. Symbols on each spatial stream are demodulated and reconstructed in the receiving processor 456 to generate a soft decision. The receiving processor 456 then decodes and deinterleaves the soft decision to reconstruct the upper layer data and control signals transmitted over the physical channel by the first communication device 410. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium.In transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between the transport channel and logical channel, packet reconstruction, decryption, header decompression, and control signal processing to reconstruct the upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0239] In transmission from the second communication device 450 to the first communication device 410, the second communication device 450 uses a data source 467 to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions in the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet splitting and reordering, and multiplexing between logical channels and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing. Next, the transmitting processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via transmitting devices 454 after analog precoding / beamforming operations in the multi-antenna transmitting processor 457. Each transmitting device 454 first converts the baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, which is then provided to the antenna 452.

[0240] In transmission from the second communication device 450 to the first communication device 410, the functions of the first communication device 410 are the same as the receiving functions of the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiving device 418 receives radio frequency signals via its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the functions of the L2 layer. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides demultiplexing between the transport channel and logical channel, packet reconstruction, decryption, header decompression, and control signal processing to recover the upper layer data packets from the UE 450. The upper layer data packets from the controller / processor 475 can then be provided to the core network.
