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 link between the first communication node device and the second communication node device, and between the two UEs through PHY 301.

[0224] 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.

[0225] The first communication device 410 comprises a controller / processor 475, memory 476, a receiving processor 470, a transmission processor 416, a multi-antenna receiving processor 472, a multi-antenna transmission processor 471, a transmission / receiving device 418, and an antenna 420.

[0226] The second communication device 450 comprises a controller / processor 459, memory 460, data source 467, transmission processor 468, receiving processor 456, multi-antenna transmission processor 457, multi-antenna receiving processor 458, transmission device / receiving device 454, and antenna 452.

[0227] 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 handles the L2 layer The following functions are implemented. In transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet splitting and reordering, multiplexing between logical channels and transport channels, and allocation of radio resources to the second communication device 450, based on various priority metrics. The controller / processor 475 is also responsible for loss retransmission and signaling to the second communication device 450. The transmission processor 416 and the multi-antenna transmission processor 471 implement various signal processing functions at the L1 layer (i.e., the physical layer). The transmission processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at 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 transmission processor 471 performs digital spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming, on encoded and modulated symbols to generate one or more spatial streams. The transmission processor 416 then maps each spatial stream to subcarriers, multiplexes them with a time-domain and / or frequency-domain reference signal (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 transmission processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmission device 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmission processor 471 into a radio frequency stream, which is then provided to different antennas 420.

[0228] 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 through 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 the logical channel, packet reconstruction, decoding, header decompression, and control signal processing to reconstruct the upper layer data packets from the core network. The upper layer data packets are then processed by all processors above the L2 layer. This is provided to the Tokor layer. Various control signals may also be provided to L3 for L3 processing.

[0229] 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 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 transmission processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmission processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, as well as beamforming processing. Next, the transmission processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which, after analog precoding / beamforming operations in the multi-antenna transmission processor 457, is provided to different antennas 452 via the transmission device 454. Each transmission device 454 first converts the baseband symbol stream provided by the multi-antenna transmission processor 457 into a radio frequency symbol stream, which is then provided to the antenna 452.

[0230] 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 through 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 a computer-readable medium. 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 the logical channel, packet reconstruction, decoding, header decompression, and control signal processing to reconstruct 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.
