Transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communications device 410, 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.

The controller/processor 459 is also responsible for retransmission of lost packets, and signaling to the second communications device 410 . The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beam forming processing, and then transmits The processor 468 modulates the generated spatial stream into a multi-carrier/single-carrier symbol stream, which undergoes analog precoding/beamforming operations in the multi-antenna transmit processor 457 and then is provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmission processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.
