Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in FIG. 4 . Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in the access network.

The first communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418 and an antenna 420.

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

In transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to the controller/processor 475 at the first communication device 410. Controller/processor 475 implements the functionality of the L2 layer. In transmission from the first communications device 410 to the first communications device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels Multiplexing, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets, and signaling to the second communications device 450 . Transmit processor 416 and multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (ie, physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communications device 450, as well as based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift Mapping of signal clusters for M-phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (eg, a pilot) in the time and/or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate A physical channel carrying a stream of time-domain multi-carrier symbols. Then the multi-antenna transmit processor 471 performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, which is then provided to a different antenna 420.

In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each Receiver 454 receives the signal via its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receive processor 456 . The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions of the L1 layer. Multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from receiver 454. The receive processor 456 converts the baseband multi-carrier symbol stream after the received analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiving processor 456, where the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458. The second communication device 450 is any spatial stream that is the destination. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover upper layer data and control signals transmitted by the first communications device 410 on the physical channel. Upper layer data and control signals are then provided to controller/processor 459. Controller/processor 459 implements the functions of the L2 layer. Controller/processor 459 may be associated with memory 460 which stores program code and data. Memory 460 may be referred to as computer-readable media. In transmission from the first communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression , control signal processing to recover upper layer packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In transmission from the second communications device 450 to the first communications device 410, a data source 467 is used to provide upper layer data packets to a controller/processor 459 at the second communications device 450. Data source 467 represents all protocol layers above the L2 layer.
