The first communication equipment450includes a controller/processor459, a memory460, a data source467, a transmitting processor468, a receiving processor456, a multi-antenna transmitting processor457, a multi-antenna receiving processor458, a transmitter/receiver454and an antenna452.

In a transmission from the second communication equipment410to the first communication equipment450, at the second communication equipment410, a higher-layer packet from a core network is provided to the controller/processor475. The controller/processor475provides functions of Layer 2. In the transmission from the second communication equipment410to the first communication equipment450, the controller/processor475provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel, and a radio resource allocation for the first communication equipment450based on various priority metrics. The controller/processor475is also in charge of retransmission of lost packets, and signalings to the first communication equipment450. The transmitting processor416and the multi-antenna transmitting processor471perform various signal processing functions used for Layer 1 (that is, PHY). The transmitting processor416performs encoding and interleaving so as to ensure FEC (Forward Error Correction) at the second communication equipment410and mappings to signal clusters corresponding to different modulation schemes (i.e., BPSK, QPSK, M-PSK M-QAM, etc.). The multi-antenna transmitting processor471processes the encoded and modulated symbols by digital spatial precoding (including precoding based on codebook and precoding based on non-codebook) and beamforming to generate one or more spatial streams. The transmitting processor416subsequently maps each spatial stream into a subcarrier to be multiplexed with a reference signal (i.e., pilot) in time domain and/or frequency domain, and then processes it with Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. Then, the multi-antenna transmitting processor471processes the time-domain multicarrier symbol streams by a transmitting analog precoding/beamforming operation. Each transmitter418converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor471into a radio frequency stream and then provides it to different antennas420.

In a transmission from the second communication equipment410to the first communication equipment450, at the first communication equipment450, each receiver454receives a signal via the corresponding antenna452.

The receiving processor456and the multi-antenna receiving processor458perform various signal processing functions of Layer 1. The multi-antenna receiving processor458processes the baseband multicarrier symbol stream coming from the receiver454by a receiving analog precoding/beamforming operation. The receiving processor458converts the baseband multicarrier symbol stream subjected to the receiving analog precoding/beamforming operation from time domain into frequency domain using FFT (Fast Fourier Transform). In frequency domain, a physical layer data signal and a reference signal are demultiplexed by the receiving processor456, wherein the reference signal is used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor458to recover any spatial stream targeting the UE450. Symbols on each spatial stream are demodulated and recovered in the receiving processor456to generate a soft decision. Then, the receiving processor456decodes and de-interleaves the soft decision to recover the higher-layer data and control signal on the physical channel transmitted by the second communication equipment410. Next, the higher-layer data and control signal are provided to the controller/processor459. The controller/processor459performs functions of Layer 2.

The controller/processor459is also in charge of retransmission of lost packets, and signalings to the second communication equipment410. The transmitting processor468conducts modulation mapping and channel encoding processing; the multi-antenna transmitting processor457performs digital multi-antenna spatial precoding (including precoding based on codebook and precoding based on non-codebook) and beaming processing; and subsequently, the transmitting processor468modulates the generated spatial streams into a multicarrier/single-carrier symbol stream, which is subjected to an analog precoding/beamforming operation in the multi-antenna transmitting processor457and then is provided to different antennas452via the transmitter454. Each transmitter452first converts the baseband symbol stream provided by the multi-antenna transmitting processor457into a radio frequency symbol stream and then provides the radio frequency symbol stream to the antenna452.

In a transmission from the first communication equipment450to the second communication equipment410, the function of the second communication equipment410is similar as the receiving function of the first communication equipment450described in the transmission from second communication equipment410to the first communication equipment450.
