     Embodiment 3

       FIG. 3  is a schematic diagram illustrating a radio protocol architecture of a user plane and a control plane. In  FIG. 3 , the radio protocol architecture for a UE and a gNB is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY  301  in the present disclosure. The layer 2 (L2)  305  is above the PHY  301 , and is in charge of the link between the UE and the gNB via the PHY  301 . In the user plane, L2  305  comprises a Medium Access Control (MAC) sublayer  302 , a Radio Link Control (RLC) sublayer  303  and a Packet Data Convergence Protocol (PDCP) sublayer  304 . All the three sublayers terminate at the gNBs of the network side. Although not described in  FIG. 3 , the UE may comprise several higher layers above the L2  305 , such as a network layer (i.e., IP layer) terminated at a P-GW  213  of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.). The PDCP sublayer  304  provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer  304  also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead. The PDCP sublayer  304  provides security by encrypting a packet and provides support for UE handover between gNBs. The RLC sublayer  303  provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by HARQ. The MAC sublayer  302  provides multiplexing between a logical channel and a transport channel. The MAC sublayer  302  is also responsible for allocating between UEs various radio resources (i.e., resource blocks) in a cell. The MAC sublayer  302  is also in charge of HARQ operation. In the control plane, the radio protocol architecture of the UE and the gNB is almost the same as the radio protocol architecture in the user plane on the PHY  301  and the L2  305 , but there is no header compression for the control plane. The control plane also comprises a Radio Resource Control (RRC) sublayer  306  in the layer 3 (L3). The RRC sublayer  306  is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the gNB and the UE.

In Downlink (DL) transmission, a higher layer packet from a core network is provided to a controller/processor  475 . The controller/processor  475  implements the functionality of the L2 layer. In DL transmission, the controller/processor  475  provides header compression, encrypting, packet segmentation and reordering, multiplexing between a logical channel and a transport channel, and radio resource allocation for the UE  450  based on various priorities. The controller/processor  475  is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the UE  450 . A transmitting processor  416  performs signal processing functions used for the L1 layer (that is, PHY). The signal processing functions include decoding and interleaving, so as to ensure a Forward Error Correction (FEC) at the UE  450  side and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM). The decoded and modulated signals are divided into parallel streams. Each of the parallel streams is mapped into multi-carrier subcarriers to be multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. The multi-carrier symbol streams are subjected to spatial precoding to generate multiple spatial streams. Each spatial stream is provided to different antennas  420  via the transmitter  418 . Each transmitter  418  modulates a Radio Frequency (RF) carrier using a corresponding spatial stream for transmitting. At the UE  450  side, every receiver  454  receives a signal via a corresponding antenna  452 . Each receiver  454  recovers information modulated onto the RF carrier and provides the information to a receiving processor  456 . The receiving processor  456  provides signal processing functions of the L1 layer. The receiving processor  456  performs spatial processing on the information to recover any UE  450 -targeted spatial stream. When a plurality of spatial streams are targeted at the UE  450 , then these spatial streams can be assembled into a single multicarrier symbol stream by the receiving processor  456 . The receiving processor  456  then converts the multi-carrier symbol stream from time domain into frequency domain using FFT. A frequency domain signal includes a single multi-carrier symbol stream of each subcarrier used for multi-carrier signals. The symbols and reference signal on each subcarrier are recovered and demodulated by determining the most possible signal cluster point transmitted by the gNB  410 , and a soft decision is generated. The soft decision is then decoded and de-interleaved so as to recover the data and control signal originally transmitted by the gNB  410  on the physical channel. The data and control signal are then provided to a controller/processor  459 . The controller/processor  459  performs functions of the L2 layer. The controller/processor can be associated with a memory  460  that stores program code and data. The memory  460  is a computer readable medium. In DL, the controller/processor  459  provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing. The controller/processor  459  also performs error detection using ACK and/or NACK protocols as a way to support HARQ operation. In uplink (UL) transmission, at the UE  450 , the data source  467  is configured to provide a higher-layer packet to the controller/processor  459 . The data source  467  represents all protocol layers above the L2 layer. Similar to a transmitting function of the gNB  410  described in DL transmission, the controller/processor  459  performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation of the gNB  410  so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor  459  is also responsible for HARQ operation, retransmission of a lost packet, and a signaling to the gNB  410 . The transmitting processor  468  selects an appropriate coding and modulation scheme to promote spatial processing. Spatial streams generated by the transmitting processor  468  are provided to different antennas  452  by a singular transmitter  454 . Each transmitter  454  modulates an RF with a corresponding spatial stream for transmitting. The transmitting function of the gNB  410  in UL transmission is similar to the function of the receiver at the UE  450 . Each receiver  418  receives a signal via a corresponding antenna  420 . Each receiver  418  recovers information modulated onto the RF carrier and then provides the information to a receiving processor  470 . The receiving processor  470  implements L1 layer functionality. The controller/processor  475  implements the L2 layer functionality. The controller/processor  475  can be associated with a memory  476  that stores program code and data. The memory  476  can be called a computer readable medium. In UL, the controller/processor  475  provides a demultiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, and control signal processing so as to recover a higher-layer packet from the UE  450 . The higher-layer packet from the controller/processor  475  can be provided to the core network. The controller/processor  475  is also in charge of error detection using ACK and/or NACK protocols to support HARQ operation.
