[0042] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0043] In order to support the transmission of URLLC services, the CG (Configured Grant) has been enhanced, that is, multiple CG configurations have been introduced, as well as the specific configuration and use of CG (such as supporting slot-level cycles, supporting automatic transmission of CG, etc.). It is necessary to consider supporting URLLC services in interference-controlled NRU (New Radio Unlicensed) scenarios. Specifically, the enhanced usage of NRU CG and ULRRC CG in NRU scenarios can be considered; the UE-initial COT for FBE triggered by the UE can also be considered in the frame-based equipment mode.

[0044] The following introduces the CG enhancement in URLLC:

[0045] In order to support the high latency requirements of URLLC services, URLLC enhances the CG cycle and supports any slot-level service cycle.

[0046] In order to support multiple URLLC services and high latency requirements of URLLC services, URLLC introduces multiple CGs. Different CGs have different HARQ (Hybrid Automatic Repeat Request) processes, and HARQ-ProcID-Offset2 (HARQ process identifier-offset 2) is used to ensure that the processes of different CGs are different.

[0047] Due to the conflict between CG resources and other resources, automatic transmission for CG is introduced to ensure that the MAC (Medium Access Control) PDU (Protocol Data Unit) (such as Deprioritized MAC PDU) that has been packaged in the CG resources is not discarded / transmitted as soon as possible. For the CG that cannot be transmitted due to resource conflict, the subsequent CG resources in the same HARQ process and the same CG configuration can be used for new transmission. The use of automatic transmission is determined by automatic transmission parameters (such as autonomousTx).

[0048] If the physical layer priorities are different: there is a conflict between CG and CG, the UE's MAC (Medium Access Control) can indicate one or more MAC PDUs (Protocol Data Units) to the physical layer. Similarly, if there is a conflict between data and SR (Scheduling Request), the MAC can also indicate SR and MAC PDU to the physical layer.

[0049] The following is the relevant content of NRU:

[0050] The goal of the NR unlicensed (NRU) mode is to enable NR to operate in unlicensed frequency bands, for example, including the following operating scenarios:

[0051] Scenario A: Carrier aggregation scenario, PCell (Primary cell) is the licensed spectrum, and SCell (Secondary Cell) working on the unlicensed spectrum is aggregated through carrier aggregation;

[0052] Scenario B: Dual-connectivity working scenario, PCell is LTE licensed spectrum, PScell ​​(Primary Secondary Cell) is NR unlicensed spectrum;

[0053] Scenario C: Independent working scenario, NR works as an independent cell in unlicensed spectrum;

[0054] Scenario D: NR single-cell scenario, UL (Uplink) works in the licensed spectrum, and DL (Downlink) works in the unlicensed spectrum;

[0055] Scenario E: Dual-connectivity working scenario, PCell is NR licensed spectrum, and PScell ​​is NR unlicensed spectrum.

[0056] Generally speaking, the operating frequency bands of NRU are 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. In the unlicensed spectrum, the design of NRU should ensure fairness with other systems that have already worked in these unlicensed spectrums, such as WiFi (Wireless Fidelity). The principle of fairness includes that the impact of NRU on systems that have already been deployed in the unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

[0057] In order to ensure fair coexistence between systems on the unlicensed spectrum, energy detection has been agreed upon as a basic coexistence mechanism. The general energy detection mechanism is the LBT (Listen Before Talk) mechanism. The basic principle of this mechanism is that before a base station or terminal (transmitter) transmits data on the unlicensed spectrum, it needs to listen for a period of time as specified. If the listening result indicates that the channel is idle, the transmitter can transmit data to the receiver. If the listening result indicates that the channel is occupied, the transmitter needs to back off for a period of time as specified and continue to listen to the channel until the channel listening result shows that it is idle before transmitting data to the receiver.

[0058] Currently, NRU includes four channel access mechanisms (category):

[0059] Mechanism (Category) 1: Direct transmission mechanism

[0060] This mechanism allows the TX side to transmit quickly after the switching gap within the COT; the switching gap refers to the switching time from receiving to transmitting, and the typical value is no more than 16us.

[0061] Category 2: LBT mechanism without random back-off

[0062] This mechanism means that the time for UE to monitor the channel is fixed, usually short, such as 25us.

[0063] Mechanism (Category) 3: LBT mechanism with random back-off (fixed contention window)

[0064] In the LBT process, the transmission side randomly selects a random value in the contention window to determine the time to listen to the channel.

[0065] Mechanism (Category) 4: LBT mechanism with random back-off (contention window is not fixed)

[0066] In the LBT process, the transmission side randomly takes a random value in the contention window to determine the time to listen to the channel. The contention window is variable.

[0067] In summary, for the terminal, the base station needs to transmit data to the terminal within the Maximum Channel Occupancy Time (MCOT). If the base station does not seize the channel, that is, outside the MCOT time, the terminal will not receive the scheduling data from the base station to the terminal.

[0068] The following describes the failure of uplink LBT in NRU:

[0069] The uplink transmission initiated by the UE mainly includes the following categories:

[0070] SR (Scheduling Request): used to request uplink resources;

[0071] PRACH (Physical Random Access Channel) transmission: Due to RACH (Random Access Channel) triggering, UE needs to send msg1 (message 1);

[0072] PUSCH (Physical Uplink Shared Channel) transmission: including uplink data transmission based on CG and uplink data transmission based on DG (Dynamic Grant);

[0073] Physical layer signaling transmission: including ACK / NACK (acknowledgement / non-acknowledgement) feedback, CSI (Channel State Information) reporting, etc.

[0074] On unlicensed bands, before transmitting SR, PRACH or PUSCH, the UE needs to use LBT to detect whether the channel is available. If it is not available, that is, LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the MAC layer needs to be notified of the LBT failure.

[0075] For example, in R16, the UE assumes that there will be only one resource that needs to be transmitted indicated from the MAC layer to the physical layer.

[0076] When resources conflict, the high priority resource may not be successfully LBTed, resulting in the failure of resource transmission and waste of resources. Therefore, the embodiment of the present application can reduce the waste of resources.

[0077] Figure 2 is a schematic flow chart of a transmission method 200 according to an embodiment of the present application. The method may optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0082] Optionally, the resources are network configured or indicated.

[0083] Exemplarily, the resource may be configured by the network through RRC signaling, or indicated through PDCCH. After receiving the configuration information in the RRC signaling or the indication information in the PDCCH, the UE may determine the transmission resource.

[0084] Optionally, the resource conflict determination method includes at least one of the following:

[0085] determining whether a resource conflict exists based on the configuration and / or the indication;

[0086] Determine whether there is a resource conflict based on the first indication information;

[0087] Whether there is a resource conflict is determined based on at least one of resource configuration, whether the data is valid, and the LBT detection result.

[0088] Exemplarily, the network may configure through RRC signaling, or indicate through PDCCH whether there is a resource conflict. After the UE receives the configuration information in the RRC signaling or the indication information in the PDCCH, it can determine whether there is a resource conflict. Optionally, the network may carry information on whether there is a resource conflict while configuring and / or indicating the resources. After the UE receives the configuration information in the RRC signaling or the indication information in the PDCCH, it can determine whether there is a resource conflict.

[0089] Exemplarily, if the UE receives the first indication information, it may indicate that there is a resource conflict.

[0090] Optionally, the first indication information includes a packaging method and / or a transmission method.

[0101] Exemplarily, the first indication information may be configured by the network through RRC signaling, or indicated through PDCCH. For example, the network may carry the first indication information while configuring and / or indicating resources. For another example, the network may carry the first indication information while configuring and / or indicating whether there is a resource conflict. For another example, the network may also send the first indication information to the UE alone.

[0102] Optionally, transmitting the target object based on the LBT detection result includes:

[0103] The target object is transmitted based on the LBT detection result and the first indication information.

[0108] In the embodiments of the present application, some information can be directly indicated to the physical layer or the physical layer can be instructed to transmit, and some information needs to be packaged before being indicated to the physical layer or the physical layer can be instructed to transmit. For example, if SR is triggered, SR can be transmitted to the physical layer. For another example, for data, the data needs to be packaged into MAC PDU, and then the MAC PDU is transmitted to the physical layer.

[0109] When grouping is required, the target objects may be grouped based only on the LBT detection result, the target objects may be grouped based only on the first indication information, or the target objects may be grouped based on the LBT detection result and the first indication information.

[0110] Optionally, the method further comprises:

[0111] The MAC layer of the terminal device sends the information to be transmitted to the physical layer of the terminal device, and the physical layer is used to transmit the information to be transmitted.

[0112] Exemplarily, the MAC layer may only perform packetization, and send the information to be transmitted obtained after packetization to the physical layer for transmission.

[0113] For example, in the case of resource conflict, the MAC layer of the UE packages the resources to be transmitted, such as PUSCH, DG, and CG, to generate a MAC PDU. Then, the packaged information to be transmitted, such as the MAC PDU, is sent to the physical layer of the UE. The physical layer transmits the packaged information to be transmitted.

[0114] For example, in the case of resource conflict, the MAC layer of the UE will instruct the physical layer to transmit the PUCCH resources corresponding to the SR when the SR is triggered. The physical layer transmits the PUCCH.

[0115] Optionally, the information to be transmitted includes at least one of the following:

[0116] MAC PDU;

[0132] Optionally, transmitting the high priority resource and / or the corresponding information to be transmitted includes:

[0133] If the LBT of a high-priority resource fails, the to-be-transmitted information corresponding to the high-priority resource will be transmitted through the resource whose LBT succeeds.

[0134] Exemplarily, the LBT of the high priority resource A fails, and the LBT of the low priority resource B succeeds. The MAC PDU, SR or HARQ-ACK feedback indication corresponding to the high priority resource A may be transmitted through the low priority resource B.

[0138] Exemplarily, the LBT of the high-priority resource A fails, and the LBT of the low-priority resource B succeeds. The MAC PDU corresponding to the high-priority resource A may be reassembled and transmitted through the low-priority resource B; or the SR or HARQ-ACK feedback corresponding to the high-priority resource A may be carried and transmitted through the low-priority resource B.

[0139] For example, the LBT of the high-priority resource A fails, and the LBT of the low-priority resource B succeeds. If the resource sizes of resource A and resource B are the same, there is no need to reassemble the packet, and the MAC PDU corresponding to the high-priority resource A can be directly transmitted through the low-priority resource B.

[0140] Optionally, transmitting each resource and / or its corresponding information to be transmitted includes:

[0141] If the LBT of the higher priority resource fails, transfer the LBT of the lower priority resource that succeeds.

[0157] Exemplarily, when the packaging method is to package the resources that have successfully passed LBT, it is necessary to obtain the LBT detection result or perform the LBT detection before determining the priority of the resource or performing the resource priority processing.

[0158] Exemplarily, when the transmission method is to transmit the LBT successful resources and / or their corresponding information to be transmitted, it is necessary to obtain the LBT detection result or perform LBT detection before determining the priority of the resource or performing resource priority processing.

[0173] Exemplarily, when the transmission method is to transmit each resource and / or its corresponding information to be transmitted, it is necessary to obtain the LBT detection result or perform LBT detection after determining the priority of the resource to be transmitted or performing resource priority processing.

[0174] Optionally, the method further comprises:

[0175] Transmit or group low-priority resources that have succeeded in LBT.

[0176] Optionally, under at least one of the following first conditions, the low priority resources for which LBT is successful are transmitted or packaged:

[0177] Low-priority resources start at the back;

[0178] The starting position of low priority resources is after the resources that failed LBT;

[0179] The starting position of low-priority resources is after high-priority resources;

[0180] The starting position of the low priority resource is after the starting position of the resource that failed LBT;

[0181] The starting position of the low priority resource is after the starting position of the high priority resource;

[0182] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the LBT failed resource;

[0183] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the high priority resource;

[0184] The starting position of the low priority resource is after the position of the first repeated transmission included in the LBT failed resource;

[0185] The starting position of the low priority resource is after the position of the first repeated transmission included in the high priority resource;

[0186] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the high priority resource;

[0187] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the resource that failed LBT;

[0188] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the high priority resource;

[0189] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the resource for which the LBT failed;

[0190] The time to perform LBT for low priority resources.

[0191] Exemplarily, the first repeated transmission mentioned above may be the last repeated transmission, the first repeated transmission, or any repeated transmission.

[0192] The transmission method of the embodiment of the present application can reduce the resources and waste caused by resource conflicts by transmitting the target object based on the LBT detection result in the case of resource conflicts. For example, in the case of resource conflicts, if the LBT of a high-priority resource fails, the information to be transmitted corresponding to the high-priority resource can also be transmitted through other resources with successful LBT, so that the resource or its corresponding information can be transmitted even in the case of LBT failure, thereby reducing or even avoiding the waste of resources caused by LBT failure.

[0193] Example 1:

[0194] In the unlicensed spectrum, in case of resource conflict, the UE packages or transmits the target object.

[0195] For example, Figure 3 As shown, the process of this method is as follows:

[0196] S310: In the unlicensed spectrum, the network configures or indicates resources to the UE, wherein the resources may be PRACH, DG, CG, PUCCH, etc.

[0197] Furthermore, the network may also send a first indication message to the UE. The first indication message is used to indicate a packetization or transmission mode. The packetization mode may include which resources the UE performs packetization on. For example, all packets, only packets with successful LBT, only packets with high priority services, packetization for specific resources, etc. The transmission mode may include how the UE transmits, for example, whether low priority resources can be transmitted in the event of a failure in LBT of high priority resources. For another example, when using resources with successful LBT for transmission, the information to be transmitted corresponding to the resources with successful LBT or the information to be transmitted corresponding to the high priority resources is transmitted. The information to be transmitted may include at least one of MAC PDU, SR and HARQ-ACK feedback indication, HARQ-ACK, and CSI-RS.

[0198] Optionally, the first indication information may be configured or indicated by the network. For example, the first indication information is carried when the network configures or indicates resources to the UE. For another example, the network configures or indicates the first indication information to the UE separately. When the network does not indicate the configuration, it may also be predefined by the protocol.

[0199] Further, there are multiple ways to determine whether there is a resource conflict. For example, the network indicates whether there is a resource conflict. For another example, the UE determines whether there is a resource conflict based on the first indication information, and specifically, for example, the UE receiving the first indication information may indicate that there is a resource conflict. For another example, the UE determines whether there is a resource conflict based on whether the resource configuration and / or data are valid.

[0200] S320: In case of resource conflict, the UE packages or transmits the target object.

[0201] For example, in the case of resource conflict, the resources of PUSCH, CG, and DG need to be packaged. Specifically, for example, the MAC layer of the UE packages the resources of PUSCH, CG, and DG and sends them to the physical layer of the UE. The physical layer transmits the packaged data.

[0202] Exemplarily, in case of resource conflict, when SR is triggered, the SR is indicated to the physical layer for transmission.

[0203] Optionally, the UE performs packet assembly according to the LBT detection result, or the UE determines / obtains transmission resources according to the LBT detection result.

[0204] Optionally, the UE determines how to assemble or transmit according to the first indication information.

[0205] Optionally, a specific example of the UE packaging or transmitting the target object may include at least one of the following:

[0206] (1) The UE only packages or transmits the resources for which LBT is successful.

[0207] i. If there are multiple resources with successful LBT or information to be transmitted corresponding to the resources with successful LBT, the UE transmits the resource with the highest priority or the information to be transmitted corresponding to the resource with the highest priority.

[0208] Exemplarily, the resources to be transmitted may include low-priority resources and high-priority resources. Among these resources, if there are multiple resources with successful LBT, the resource with the highest priority among the resources with successful LBT can be used for transmission. That is, the resource with the highest priority or the information to be transmitted corresponding to the resource with the highest priority is transmitted.

[0209] Exemplarily, if there is information to be transmitted corresponding to multiple resources with successful LBT, the resource with the highest priority among the resources with successful LBT may be used to transmit the information to be transmitted corresponding to the resource with the highest priority.

[0210] ii. Optionally, if the LBT detection result is obtained or the LBT detection is performed before determining the priority (prioritization) of the resources to be transmitted or before performing the priority processing, the UE only packages or transmits the resources for which the LBT is successful.

[0211] (2) The UE only packages or transmits high-priority resources.

[0212] i. If the LBT of the high-priority resource fails, the UE transmits the to-be-transmitted information corresponding to the high-priority resource through the resource with successful LBT. For example, when the size of the high-priority resource is the same as that of the resource with successful LBT, the to-be-transmitted information corresponding to the high-priority resource is transmitted through the resource with successful LBT. For another example, the high-priority resource is reassembled. In one case, when the size of the high-priority resource is different from that of the resource with successful LBT, the MAC PDU of the high-priority resource is reassembled and transmitted through the resource with successful LBT.

[0213] ii. Optionally, the UE may obtain the LBT detection result or perform LBT detection before determining the priority (prioritization) of the resources to be transmitted or before performing priority processing, or obtain the LBT detection result or perform LBT detection after determining the priority (prioritization) of the resources to be transmitted or after performing priority processing.

[0214] (3) The UE packages or transmits each resource.

[0215] Specifically, each resource is packaged, and the physical layer transmits part of the resources (such as one resource); or, the information to be transmitted corresponding to each resource is indicated to the physical layer, and the physical layer transmits part of the information to be transmitted (such as one information to be transmitted).

[0216] Furthermore, when certain conditions are met, the UE may package or transmit each resource. The first condition is at least one of the following:

[0217] Low-priority resources start at the back;

[0218] The starting position of low priority resources is after the resources that failed LBT;

[0219] The starting position of low-priority resources is after high-priority resources;

[0220] The starting position of the low priority resource is after the starting position of the resource that failed LBT;

[0221] The starting position of the low priority resource is after the starting position of the high priority resource;

[0222] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the LBT failed resource;

[0223] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the high priority resource;

[0224] The starting position of the low priority resource is after the position of the first repeated transmission included in the LBT failed resource;

[0225] The starting position of the low priority resource is after the position of the first repeated transmission included in the high priority resource;

[0226] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the high priority resource;

[0227] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the resource that failed LBT;

[0228] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the high priority resource;

[0229] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the resource for which the LBT failed;

[0230] The time to perform LBT for low priority resources.

[0231] i. If the LBT of the high-priority resource fails, the UE transmits the low-priority resource (in this case, the LBT of the low-priority resource is successful), or the UE transmits the to-be-transmitted information corresponding to the high-priority resource through the resource with successful LBT. For example, when the size of the high-priority resource is the same as that of the resource with successful LBT, the to-be-transmitted information corresponding to the high-priority resource is transmitted through the resource with successful LBT. For another example, the high-priority resource is reassembled. In one case, when the size of the high-priority resource is different from that of the resource with successful LBT, the MAC PDU reassembled packet of the high-priority resource is transmitted through the resource with successful LBT.

[0232] ii. Optionally, if the LBT detection result is obtained or the LBT detection is performed after determining the priority of the resource to be transmitted or after performing the priority processing, the UE packages each resource. If the LBT of the high-priority resource fails, the UE transmits the low-priority resource, or the UE transmits the information to be transmitted corresponding to the high-priority resource through the resource with successful LBT.

[0233] (4) The UE may or may also package or transmit low priority resources.

[0234] i. If there are multiple low-priority resources, the resources in which LBT is successfully transmitted are grouped or transmitted.

[0235] ii. If there are multiple low-priority resources, the resource with the highest priority is packaged or transmitted.

[0236] iii. Optionally, if the LBT detection result is obtained or the LBT detection is performed after determining the priority (prioritization) of the resources to be transmitted or after performing priority processing, or if the resource priority processing and the LBT detection are performed in no particular order, the UE can also package or transmit low-priority resources.

[0237] Further, when certain conditions are met, the UE may or may also package or transmit low-priority resources. The first condition is at least one of the following:

[0238] Low-priority resources start at the back;

[0239] The starting position of low priority resources is after the resources that failed LBT;

[0240] The starting position of low-priority resources is after high-priority resources;

[0241] The starting position of the low priority resource is after the starting position of the resource that failed LBT;

[0242] The starting position of the low priority resource is after the starting position of the high priority resource;

[0243] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the LBT failed resource;

[0244] The starting position of the low priority resource is after the starting position of the first repeated transmission included in the high priority resource;

[0245] The starting position of the low priority resource is after the position of the first repeated transmission included in the LBT failed resource;

[0246] The starting position of the low priority resource is after the position of the first repeated transmission included in the high priority resource;

[0247] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the high priority resource;

[0248] The DCI scheduling time of the low priority resource is after the DCI scheduling time of the resource that failed LBT;

[0249] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the high priority resource;

[0250] The reception time of the DCI scheduling of the low priority resource is after the reception time of the DCI scheduling of the resource for which the LBT failed;

[0251] The time to perform LBT for low priority resources.

[0252] The transmission method of the embodiment of the present application is a packet assembly and / or resource transmission method when there is a resource conflict on an unlicensed frequency band, which can reduce or even avoid resource waste caused by LBT failure.
