     BACKGROUND 
     Technical Field 
     The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a communication method and device that support data transmission on Unlicensed Spectrum. 
     Related Art 
     In 5G system, Enhance Mobile Broadband (eMBB) and Ultra Reliable and Low Latency Communication (URLLC) are two typical business types. In 3rd Generation Partner Project (3GPP) New Radio (NR) Release 15, a new Modulation and Coding Scheme (MCS) table targeting lower target Block Error Rate (BLER) required for URLLC business was defined. 
     With a purpose of supporting more demanding URLLC business, for example, with higher reliability (e.g., a target BLER is 10{circumflex over ( )}−6) or with lower delay (e.g., 0.5-1 ms), a Study Item (SI) on URLLC advancement in NR Release 16 was approved at the 3GPP Radio Access Network (RAN) #80th Plenary Session. In the SI, the advancement in Hybrid Automatic Repeat reQuest (HARQ) feedback/Channel State Information (CSI) feedback has been a focus of the study. 
     SUMMARY 
     The inventors have found through researches that Uplink Control Information (UCI) includes HARQ/CSI. When a PUCCH reserved for transmission of UCI and a PUSCH are not orthogonal in time domain, in order to support more reliable transmission in NR Release 16, how to transmit UCI becomes a significant problem needed to be reconsidered. 
     In view of the above problem, the present disclosure provides a solution. It should be noted that the embodiments of the present disclosure and the characteristics in the embodiments can be arbitrarily combined if there is no conflict. 
     The present disclosure discloses a method in a User Equipment (UE) for wireless communication, comprising: 
     receiving a first signaling, the first signaling being used for determining a first time-frequency resource; 
     receiving a second signaling, the second signaling being used for determining a second time-frequency resource; and 
     transmitting a first bit block in the first time-frequency resource, or, transmitting a first bit block in the second time-frequency resource; 
     herein, time domain resource occupied by the first time-frequency resource and time domain resource occupied by the second time-frequency resource are non-orthogonal; the first signaling carries a first identifier or a second identifier; whether the first signaling carries the first identifier or the second identifier is used to determine whether the first bit block is transmitted in the first time-frequency resource or transmitted in the second time-frequency resource. 
     In one embodiment, a problem needed to be solved in the present disclosure is how to achieve advancement in UCI transmission in order to meet the requirement for higher reliability in NR Release 16 when a PUCCH and a PUSCH are non-orthogonal in time domain. 
     In one embodiment, a problem needed to be solved in the present disclosure is: in the existing standards, when a PUCCH reserved for transmitting UCI is not orthogonal with a PUSCH in time domain, UCI will be shifted to be transmitted on the PUSCH. However, in the NR Release 16, a PUCCH reserved for transmitting UCI in URLLC business has higher transmission reliability. If the PUCCH is not orthogonal with a PUSCH (eMBB/URLLC business) in time domain, and methods in the present standards remain to be used, the UCI will be shifted to be transmitted on a PUSCH, and the transmission reliability of the UCI will probably not be guaranteed. Therefore, in order to support the requirement for higher reliability posed by NR Release 16, when a PUCCH and a PUSCH are non-orthogonal in time domain, how to transmit UCI becomes a crucial problem in need of reconsideration. 
     In one embodiment, the essence of the above method lies in that a first time-frequency resource is a PUCCH, a second time-frequency resource is a PUSCH, a first bit block is UCI, the PUCCH and the PUSCH are non-orthogonal in time domain, a first identifier and a second identifier are both Radio Network Temporary Identifiers (RNTIs) used for scrambling CRC of DCI, wherein the first identifier is for URLLC business, while the second identifier is for eMBB business. An advantage of using the above method is that whether UCI is transmitted on a PUCCH or a PUSCH can be determined based on an RNTI for scrambling the CRC of the DCI. 
     In one embodiment, the above method is characterized in that if the first signaling carries the first identifier, then the first bit block is transmitted in the first time-frequency resource or the first bit block is transmitted in the second time-frequency resource, if the first signaling carries the second identifier, then the first bit block is only transmitted in the second time-frequency resource between the first time-frequency resource and the second time-frequency resource. 
     In one embodiment, the essence of the above method lies in that when a PUCCH reserved for transmitting UCI is not orthogonal with a PUSCH in time domain, if the UCI is for eMBB, then the UCI is transmitted using methods in conformity with the present standards, namely, the UCI is transmitted on the PUSCH; or if the UCI is for URLLC, then the UCI may be transmitted either on the PUCCH or the PUSCH. 
     In one embodiment, the above method is characterized in that the first signaling carries the first identifier, a relative positional relation or a relative numerical relation between the time domain resource occupied by the first time-frequency resource and the time domain resource occupied by the second time-frequency resource is used for determining whether the first bit block is transmitted in the first time-frequency resource or is transmitted in the second time-frequency resource; or, the first signaling carries the first identifier, the second signaling carries the first identifier or the second identifier, whether the second signaling carries the first identifier or the second identifier is used for determining whether the first bit block is transmitted in the first time-frequency resource or is transmitted in the second time-frequency resource. 
     In one embodiment, the essence of the above method lies in that when a PUCCH reserved for URLLC UCI is not orthogonal with a PUSCH in time domain, whether URLLC UCI is transmitted on the PUCCH or on the PUSCH is related to a relative positional relation between time domain resource comprised in the PUCCH and time domain resource comprised in the PUSCH, or is related to a relative numerical relation between the time domain resource comprised in the PUCCH and the time domain resource comprised in the PUSCH, or is related to whether the PUSCH is for eMBB business or URLLC business.

     if the first bit block is transmitted in the second time-frequency resource, then a second radio signal is also transmitted in the second time-frequency resource;

An advantage of the above method is that if each bit in eMBB UCI or less demanding URLLC UCI is transmitted in each time-frequency resource of K time-frequency resources, then eMBB UCI or less demanding URLLC UCI will be repeatedly transmitted so as to enhance transmission reliability; if each bit in eMBB UCI or less demanding URLLC UCI is only transmitted in one or multiple time-frequency resources of the K time-frequency resources, a smaller PUCCH resource can be chosen to transmit UCI, thereby improving resource utilization, and increasing the system transmission capacity.

     To achieve higher transmission reliability and lower latency, transmitting the same URLLC UCI repeatedly on multiple PUCCHs within a slot is a research orientation of NR Release 16. If UCI needed to be transmitted within a slot includes demanding URLLC UCI, which needs to be transmitted multiple times, and eMBB UCI/less demanding URLLC UCI, which needs to be transmitted only once; the demanding URLLC UCI is transmitted on each PUCCH of the multiple PUCCHs; each bit in eMBB UCI or less demanding URLLC UCI is transmitted on each PUCCH of the multiple PUCCHs, or is only transmitted on one or multiple PUCCHs of the multiple PUCCHs. An advantage of the above method is that if each bit in eMBB UCI or less demanding URLLC UCI is transmitted on each PUCCH of the multiple PUCCHs, then the eMBB UCI or less demanding URLLC UCI will be repeatedly transmitted so as to enhance transmission reliability; if each bit in eMBB UCI or less demanding URLLC UCI is only transmitted in one or multiple PUCCHs of the multiple PUCCHs, a smaller PUCCH resource can be chosen to transmit the UCI, thereby improving resource utilization, and increasing the system transmission capacity.

     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 base station (gNB or 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 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 Hybrid Automatic Repeat reQuest (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 block) 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.
