     The present application 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 
     In 5G systems, Enhance Mobile Broadband (eMBB) and Ultra Reliable and Low Latency Communication (URLLC) are two typical service types. Targeting requirements for lower target Block Error Ratio (BLER) of URLLC services, a new Modulation and Coding Scheme (MCS) table has been defined in 3rd Generation Partner Project (3GPP) New Radio (NR) Release 15. 
     1. In order to support higher reliability (for example: a target BLER is 10{circumflex over ( )}-6) and lower delay (for example: 0.5-1 ms) required by URLLC services, in 3GPP NR Release 16, a Downlink Control Information (DCI) signaling can indicate whether scheduled services are of low Priority or high Priority, where the high priority corresponds to URLLC services, and the low priority corresponds to eMBB services. 
     A Work Item (WI) of Ultra-reliable and Low Latency Communications (URLLC) enhancement in NR Release 17 was approved at 3GPP RAN Plenary, where the multiplexing of different Intra-User Equipment (UE) services is a focus to be researched. 
     2. 3GPP NR Release 16 has supported multiple repetition-based uplink transmission modes, comprising a transmission mode of PUSCH repetition type B. 
     A Work Item (WI) of URLLC enhancement in NR Release 17 was approved at 3GPP RAN Plenary, where URLLC services performed on the NR Unlicensed Spectrum (NR-U) is a focus to be researched. 
     SUMMARY 
     A. After introducing the multiplexing of different intra-UE priority services, the UE can multiplex Uplink Control Information (UCI) with different priorities onto a same Physical Uplink Control Channel (PUCCH) for transmission; the UE may need to reselect PUCCH resources during the multiplexing procedure. How to deal with the collision with other channels incurred by PUCCH resource reselection is a key problem to be solved. 
     To address the above problem, the present application provides a solution.

Additionally, the adoption of a unified solution for various scenarios (including but not limited to Uplink, Downlink and Sidelink) contributes to the reduction of hardcore complexity and costs.

     Embodiment 3 
     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 application, 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 an RSU in V2X) and a second communication node (gNB, UE or an 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 application. 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, as well as two UEs via the PHY  301 . 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 in the present application, 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 the transmission from the first communication device  410  to the first communication device  450 , the controller/processor  475  provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resources allocation to the second communication device  450  based on various priorities. The controller/processor  475  is also responsible for retransmission of a lost packet and a signaling to the second communication device  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 spatial streams. The transmitting processor  416  then maps each spatial 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 multicarrier symbol streams. After that the multi-antenna transmitting processor  471  performs transmission analog precoding/beamforming on the time-domain multicarrier 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 the second communication device-targeted spatial stream. Symbols on each spatial 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 the transmission from the first communication device  410  to the second communication device  450 , 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. 
     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 the transmission from the first communication device  410  to the second communication device  450 , 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 resources allocation 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 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 spatial 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. In the transmission from the second communication device  450  to the first communication device  410 , 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 UE  450 . The higher-layer packet coming from the controller/processor  475  may be provided to the core network.
