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. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

The first communications 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 an antenna 452.

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

In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller/processor 475. The controller/processor 475 implements the functionality of layer L2. In transmissions from the second 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, and radio resource allocation to the first communications device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets, and signaling to the first 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) at the second communication device 410, as well as mapping of signal constellation based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature 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, including codebook-based precoding and non-codebook based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate the physical channels carrying the time-domain multicarrier symbol streams. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In a transmission from the second communications apparatus 410 to the first communications apparatus 450, each receiver 454 receives a signal through its respective antenna 452 at the first communications apparatus 450. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. Receive processor 456 converts the baseband multicarrier symbol stream after the receive 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 signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communications device 410 on the physical channel. The upper layer data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the functionality of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In transmissions from the second communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the core network. The upper layer packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In a transmission from the first communications device 450 to the second communications device 410, a data source 467 is used at the first communications device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the send function at the second communications apparatus 410 described in the transmission from the second communications apparatus 410 to the first communications apparatus 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to said second communications device 410. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a transmitter 454 after analog precoding/beamforming in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the receiving functionality at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives an rf signal through its respective antenna 420, converts the received rf signal to a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multiple antenna receive processor 472 collectively implement the functionality of the L1 layer. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In transmission from the first communications device 450 to the second communications device 410, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the UE 450. Upper layer data packets from the controller/processor 475 may be provided to a core network.
