Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system and NR (New Radio) system. By configuring multiple antennas at a communication node, such as a base station or a UE (User Equipment, user equipment), additional spatial freedom is obtained. Multiple antennas are beam-forming to form beams pointing to a specific direction to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of the two communication parties need to be aligned in order to carry out effective communication. When the sending/receiving beam is out of sync due to UE movement, etc., the communication quality will be greatly reduced or even communication will not be possible.

The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and 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)) constellation mapping. The multi-antenna transmission 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 parallel streams. The transmit processor 416 then maps each parallel stream to subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilot) in the time and/or frequency domain, and then uses inverse fast Fourier transform (IFFT) ) To generate a physical channel carrying a multi-carrier symbol stream in the time domain. Subsequently, the multi-antenna transmission processor 471 performs transmission simulation 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 transmission processor 471 into a radio frequency stream, and then provides it to a different antenna 420.

Each receiver 454 recovers the information modulated on the radio frequency carrier, and converts the radio frequency stream into a baseband multi-carrier symbol stream and provides it 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 reception analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454.
