[0005] The present application relates to a transmission method and apparatus in a wireless communication system, and in particular to a communication method and apparatus supporting data transmission on an unlicensed spectrum. Background Art

[0006] In the 5G system, eMBB (Enhance Mobile Broadband) and URLLC (Ultra Reliable and Low Latency Communication) are two typical service types. In the 3GPP (3rd Generation Partner Project) new air interface Release 15, a new modulation and coding scheme (MCS) table has been defined for the lower target BLER requirement (10^-5) of URLLC services.

[0007] In order to support URLLC services with higher requirements, such as higher reliability (for example, target BLER is 10^-6), lower latency (for example, 0.5-1ms), etc., the URLLC enhanced SI (Study Item) of the new air interface Release 16 was passed at the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #80 plenary meeting. Among them, the enhancement of HARQ (Hybrid Automatic RepeatreQuest) feedback / CSI (Channel State Information) feedback is a key point to be studied. Summary of the invention

[0008] The inventors have found through research that UCI includes HARQ / CSI. When a PUCCH reserved for sending UCI (Uplink Control Information) is not orthogonal to PUSCH in the time domain, in order to support higher reliability transmission in the new air interface Release 16, how to send UCI is a key issue that needs to be reconsidered.

[0009] In view of the above problems, the present application discloses a solution. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other.

[0010] The present application discloses a method in a user equipment for wireless communication, characterized by comprising:

[0011] - receiving a first signaling, where the first signaling is used to determine a first time-frequency resource group, where the first time-frequency resource group is reserved for transmission of a first bit block;

[0012] -sending K wireless signals and the first bit block in K time-frequency resource groups;

[0013] Among them, the time domain resources occupied by the first time-frequency resource group and the time domain resources occupied by at least one of the K time-frequency resource groups are overlapping, and any two of the K time-frequency resource groups are mutually orthogonal in the time domain; the K wireless signals are sent in the K time-frequency resource groups respectively, and the first bit block is sent in only K1 time-frequency resource groups among the K time-frequency resource groups; the first signaling corresponds to the first type or the second type, and whether the first type or the second type corresponding to the first signaling is used to determine the K1 time-frequency resource groups from the K time-frequency resource groups; the K is a positive integer greater than 1, and the K1 is a positive integer not greater than the K.

[0014] As an embodiment, the problem to be solved by the present application is: in view of the requirement of the new air interface Release 16 for higher reliability, when the PUCCH is not orthogonal to the PUSCH in the time domain, how to enhance the transmission of UCI.

[0015] As an embodiment, the problem to be solved by the present application is: in the existing standard, when the PUCCH reserved for sending UCI is not orthogonal to a PUSCH in the time domain, the UCI is sent on this PUSCH instead. In the new air interface Release 16, a PUSCH may occupy only a few time domain resources, such as 1 or several multi-carrier symbols, and there may be multiple PUSCHs sent in the same time slot or subframe of the same carrier. These multiple PUSCHs may be multiple repeated transmissions of a TB (Transport Block) or may be transmissions of multiple different TBs; when UCI is not orthogonal to at least one of the multiple PUSCHs, which PUSCH or PUSCHs to place the UCI on for transmission is a key issue that needs to be reconsidered.

[0016] As an embodiment, the problem to be solved by the present application is: in the existing standard, when the PUCCH reserved for sending UCI is not orthogonal to a PUSCH in the time domain, the UCI is sent on this PUSCH instead. In the new air interface Release 16, a URLLC PUSCH may occupy only a small amount of time domain resources, such as 1 or several multi-carrier symbols. There may be multiple URLLC PUSCHs sent in the same time slot or subframe of the same carrier. These multiple URLLC PUSCHs may be multiple repeated transmissions of a TB or may be transmissions of multiple different TBs; since the eMBB UCI and URLLC UCI have different requirements for transmission delay, when the UCI is not orthogonal to at least one of the multiple URLLC PUSCHs, the service type corresponding to the UCI needs to be considered when placing the UCI on which one or which PUSCHs to transmit.

[0017] As an embodiment, the essence of the above method is that the first time-frequency resource group is PUCCH, K time-frequency resource groups are K PUSCHs, the first bit block is UCI, the PUCCH and at least one PUSCH of the K PUSCHs are not orthogonal in the time domain, the first type is for URLLC services, and the second type is for eMBB services. The advantage of using the above method is that it is determined on which PUSCH or PUSCHs of the K PUSCHs the UCI is sent according to the service type corresponding to the UCI.

[0018] According to one aspect of the present application, the above method is characterized in that if the first signaling corresponds to the first type, the K1 time-frequency resource groups are respectively the earliest K1 time-frequency resource groups in the time domain among the K2 time-frequency resource groups; each time-frequency resource group in the K2 time-frequency resource groups is a time-frequency resource group among the K time-frequency resource groups, and the K2 is a positive integer not less than the K1 and not greater than the K; the K2 is equal to the K and the K2 time-frequency resource groups are respectively the K time-frequency resource groups, or the K2 time-frequency resource groups are all time-frequency resource groups among the K time-frequency resource groups that overlap with the first time-frequency resource group in the time domain.

[0019] As an embodiment, the essence of the above method is that the K2 time-frequency resource groups are K2 PUSCHs among the K PUSCHs, and the URLLC UCI is sent in the earliest K1 PUSCHs in the time domain among the K2 PUSCHs. The advantage of adopting the above method is that it ensures low transmission delay of the URLLC UCI.

[0020] According to one aspect of the present application, the above method is characterized in that if the first signaling corresponds to the second type, the K1 time-frequency resource groups are respectively the latest K1 time-frequency resource groups in the time domain among the K3 time-frequency resource groups; each time-frequency resource group in the K3 time-frequency resource groups is a time-frequency resource group among the K time-frequency resource groups, and the K3 is a positive integer not less than the K1 and not greater than the K; the K3 is equal to the K and the K3 time-frequency resource groups are respectively the K time-frequency resource groups, or the K3 time-frequency resource groups are all time-frequency resource groups among the K time-frequency resource groups that overlap with the first time-frequency resource group in the time domain.

[0021] As an embodiment, the essence of the above method is that the K time-frequency resource groups are K URLLC PUSCHs, and in order to ensure the high transmission reliability of URLLC PUSCH, these K URLLC PUSCHs are repeated transmissions of the same TB, and the K3 time-frequency resource groups are K3 PUSCHs among the K URLLC PUSCHs, and the eMBB UCI is sent in the latest K1 PUSCH in the time domain among the K3 PUSCHs. The advantage of using the above method is that when K3 is greater than K1, the eMBB UCI will not affect the transmission of the earliest K3-K1 PUSCHs among the K3 URLLCPUSCHs, and the receiving end may successfully decode this TB earlier based on multiple repeated transmissions, which is beneficial to the low transmission delay of URLLC PUSCH.

[0282] Example 3

[0283] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown.

[0284] Attached Figure 3is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, Figure 3 The radio protocol architecture for user equipment (UE) and base station equipment (gNB or eNB) is shown in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between UE and gNB through PHY301. In the user plane, L2 layer 305 includes MAC (Medium Access Control) sublayer 302, RLC (Radio Link Control) sublayer 303, and PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, provides security by encrypting data packets, and provides handover support for UEs between gNBs. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell between UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for UE and gNB is substantially the same for the physical layer 301 and L2 layer 305, but there is no header compression function for the control plane. The control plane also includes the RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configuring lower layers using RRC signaling between the gNB and the UE.
