Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the priority benefit of Chinese Patent Application 202110029619.5, filed on Jan. 11, 2021, the full disclosure of which is incorporated herein by reference. 
     BACKGROUND 
     Technical Field 
     The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a method and device of radio signal transmission in a wireless communication system supporting cellular networks. 
     Related Art 
     How to support transmission of multicast and broadcast services under 5G architecture was discussed in New Radio (NR) Release (R) 17. In traditional Long-Term Evolution (LIE) and Long-Term Evolution Advanced (LTE-A) systems, a base station supports a terminal in receiving multicast and groupcast services through methods of Multicast Broadcast Single Frequency Network (MBSFN) and Single-Cell Point-To-Multipoint (SC-PTM). 
     In NR system, large-scale Massive Multiple Input Multiple Output (MIMO) is an important technical feature. For the massive MIMO, large-scale antenna matrix forms a relatively narrow beam to point to a specific direction to improve the quality of communications. Since beams formed by the large-scale antenna matrix are generally narrow, beams from both sides of communications shall be aligned to enable effective communications. For this purpose, the NR system introduces a beam management mechanism, including beam measurement, feedback, update, indication, beam failure recovery and other functions. 
     SUMMARY 
     Inventors found through researches that compared with the traditional multicast groupcast services, differences of PTM/multicast groupcast services in the NR system include that beam gain of large-scale antenna matrix can be used to improve the performance of PTM/multicast groupcast services. How to enhance the existing beam management mechanism to support the PTM/multicast groucast services is a problem to be solved. 
     To address the above problem, the present disclosure provides a solution. It should be noted that although the above description uses large-scale MIMO and beam-based communication scenarios as examples, the application is also applicable to other scenarios, such as LIE multi-antenna systems, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios (including but not limited to large-scale MIMO, beam-based communications and LIE multi-antenna systems) contributes to the reduction of hardware complexity and costs. If no conflict is incurred, embodiments in any node in the present disclosure and the characteristics of the embodiments are also applicable to any other node, and vice versa. And the embodiments in the present disclosure and the characteristics in the embodiments can be arbitrarily combined if there is no conflict.

     Embodiment 3 illustrates a schematic diagram of an example of a radio protocol architecture of a user plane and a control plane according to one embodiment of the present disclosure, as shown in  FIG. 3 .  FIG. 3  is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane  350  and a control plane  300 . In  FIG. 3 , the radio protocol architecture for a first communication node (UE, gNB or RSU in V2X) and a second communication node (gNB, UE or RSU in V2X), or between two UEs 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 a link between a first communication node and a second communication node, or between two UEs. 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 second communication node. The PDCP sublayer  304  provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer  304  provides security by encrypting a packet and provides support for a first communication node handover between second communication nodes. The RLC sublayer  303  provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a data 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 first communication nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer  302  is also in charge of HARQ operation. The Radio Resource Control (RRC) sublayer  306  in layer 3 (L3) of the control plane  300  is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer with an RRC signaling between a second communication node and a first communication node device. The radio protocol architecture of the user plane  350  comprises layer 1 (L1) and layer 2 (L2). In the user plane  350 , the radio protocol architecture for the first communication node and the second communication node is almost the same as the corresponding layer and sublayer in the control plane  300  for physical layer  351 , PDCP sublayer  354 , RLC sublayer  353  and MAC sublayer  352  in L2 layer  355 , but the PDCP sublayer  354  also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead. The L2 layer  355  in the user plane  350  also includes Service Data Adaptation Protocol (SDAP) sublayer  356 , which is responsible for the mapping between QoS flow and Data Radio Bearer (DRB) to support the diversity of traffic. Although not described in  FIG. 3 , the first communication node may comprise several higher layers above the L2 layer  355 , such as a network layer (e.g., IP layer) terminated at a P-GW of the network side and an application layer terminated at the other side of the connection (e.g., a peer UE, a server, etc.).

     Embodiment 4 
     Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to one embodiment of the present disclosure, as shown in  FIG. 4 .  FIG. 4  is a block diagram of a first communication device  410  in communication with a second communication device  450  in an access network. 
     The first communication device  410  comprises a controller/processor  475 , a memory  476 , a receiving processor  470 , a transmitting processor  416 , a multi-antenna receiving processor  472 , a multi-antenna transmitting processor  471 , a transmitter/receiver  418  and an antenna  420 . 
     The second communication device  450  comprises a controller/processor  459 , a memory  460 , a data source  467 , a transmitting processor  468 , a receiving processor  456 , a multi-antenna transmitting processor  457 , a multi-antenna receiving processor  458 , a transmitter/receiver  454  and an antenna  452 . 
     In a transmission from the first communication device  410  to the second communication device  450 , at the first communication device  410 , a higher layer packet from the core network is provided to a controller/processor  475 . The controller/processor  475  provides a function of the L2 layer. In DL transmission, the controller/processor  475  provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation for the second communication device  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 second communication node  450 . The transmitting processor  416  and the multi-antenna transmitting processor  471  perform various signal processing functions used for the L1 layer (that is, PHY). The transmitting processor  416  performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device  450 , and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor  471  performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more parallel streams. The transmitting processor  416  then maps each parallel stream into a subcarrier. The mapped symbols are 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. After that the multi-antenna transmitting processor  471  performs transmission analog precoding/beamforming on the time-domain multi-carrier symbol streams. Each transmitter  418  converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor  471  into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas  420 . 
     In a transmission from the first communication device  410  to the second communication device  450 , at the second communication device  450 , each receiver  454  receives a signal via a corresponding antenna  452 . Each receiver  454  recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor  456 . The receiving processor  456  and the multi-antenna receiving processor  458  perform signal processing functions of the L1 layer. The multi-antenna receiving processor  458  performs receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver  454 . The receiving processor  456  converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor  456 , wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor  458  to recover any second communication device  450 -targeted parallel stream. Symbols on each parallel stream are demodulated and recovered in the receiving processor  456  to generate a soft decision. Then the receiving processor  456  decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the first communication node  410 . Next, the higher-layer data and control signal are provided to the controller/processor  459 . The controller/processor  459  performs functions of the L2 layer. The controller/processor  459  can be connected to a memory  460  that stores program code and data. The memory  460  can be called a computer readable medium. In downlink (DL) transmission, 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 a transmission from the second communication device  450  to the first communication device  410 , at the second communication device  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 first communication device  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 first communication device  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 first communication device  410 . The transmitting processor  468  performs modulation mapping and channel coding. The multi-antenna transmitting processor  457  implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated parallel streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor  468 , and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor  457  and provided from the transmitters  454  to each antenna  452 . Each transmitter  454  first converts a baseband symbol stream provided by the multi-antenna transmitting processor  457  into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna  452 . 
     In the transmission from the second communication device  450  to the first communication device  410 , the function of the first communication device  410  is similar to the receiving function of the second communication device  450  described in the transmission from the first communication device  410  to the second communication device  450 . Each receiver  418  receives a radio frequency signal via a corresponding antenna  420 , converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor  472  and the receiving processor  470 . The receiving processor  470  and multi-antenna receiving processor  472  collectively provide functions of the L1 layer. The controller/processor  475  provides functions of the L2 layer. The controller/processor  475  can be connected with the memory  476  that stores program code and data. The memory  476  can be called a computer readable medium. the controller/processor  475  provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the second communication device  450 . The higher-layer packet coming from the controller/processor  475  may be provided to the core network. The controller/processor  475  can also perform error detection using ACK and/or NACK protocols to support HARQ operation.
