CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/CN2017/115345, filed on Dec. 8, 2017, claiming the priority benefit of International Application PCT/CN2017/115345, filed on Dec. 8, 2017, the full disclosure of which is incorporated herein by reference. 
    
    
     BACKGROUND 
     Technical Field 
     The present disclosure relates to methods and devices of radio signal transmission in wireless communication systems, and in particular to a method and device of radio signal transmission in a wireless communication system that supports cellular networks. 
     Related Art 
     In a traditional 3 rd  Generation Partner Project (3GPP) Long-term Evolution (LTE) system, data transmission only occurs on Licensed Spectrum. However, as traffic flow began to skyrocket, particularly in some urban areas, the Licensed Spectrum may hardly meet growing demands for traffic, therefore, in Release 13 and Release 14 communications on Unlicensed Spectrum is introduced into a cellular system and used for downlink and uplink data transmissions. To ensure compatibility with other access technologies on Unlicensed Spectrum, the technique of Listen Before Talk (LBT) is adopted by Licensed Assisted Access (LAA) so as to prevent interference caused by multiple transmitters occupying a same frequency resource at the same time. A transmitter in LTE system adopts quasi-omnidirectional antennas in performing LBT. 
     At present, technical discussions about 5G New Radio (NR) are in progress, which include Massive Multi-Input-Multi-Output (MIMO), a new hot topic of study on next generation mobile communications. In Massive MIMO, a plurality of antennas form through beamforming a beam pointing in a specific spatial direction to improve communication quality. When considering characteristics of coverage brought about by beamforming, a traditional LAA technology needs to be reconsidered, such as an LBT scheme. 
     SUMMARY 
     Inventors find through researches that beamforming will be applied in large-scale in 5G systems, and beamforming-based LBT scheme will influence the transmission of control information and data. Since measurements on a plurality of beams will lead to more than one LBT process, and these LBT processes correspond to multiple transmissions of control information and data, how to manage the control information and data transmissions corresponding to the multiple LBTs with high efficiency becomes a key issue to be solved. 
     To address the above problem, the present disclosure provides a solution.

     Embodiment 3 
     Embodiment 3 illustrates a schematic diagram of a radio protocol architecture of a user plane and a control plane, as shown in  FIG. 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 base station (gNB, eNB) 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 protocol 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 an 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.
