Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301.

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 410 and a second communication device 450 in communication with each other in an 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 an antenna 452.

In the transmission from the first communication device 410 to the second communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the first communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the first communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, 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 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., physical layer). Transmit processor 416 performs 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., 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 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, 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 a physical channel carrying the time domain multicarrier symbol stream. 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 multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the first communication device 410 to the second communication device 450, each receiver 454 receives a signal at the second communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier 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 for 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. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the 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 receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. A receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the first communication device 410 on the physical channel. 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 receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium.
