Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an uplink transmission method, uplink transmission device, and terminal. Background Technology

[0002] Frame-based equipment (FBE) uses a periodic structure for its transmit / receive timing, with a period of a fixed frame period (FFP).

[0003] The FBE node occupies the channel using a Listen Before Talk (LBT) channel access mechanism and starts transmission at the beginning of a certain FFP after accessing the channel.

[0004] Specifically, the FBE initiating node needs to perform Clear Channel Assessment (CCA) before initiating transmission at the start of a certain FFP. If the channel is determined to be idle, transmission can begin immediately; otherwise, transmission is not allowed for the subsequent FFP duration. Furthermore, the FBE initiating node can transmit multiple times on a specified channel within the Channel Occupation Timer (COT) of an already started FFP without performing additional CCA, as long as the time interval between adjacent transmissions does not exceed 16 μs.

[0005] However, within a transport cluster, the FBE sending node needs to perform LBT for each transport, which affects transport performance. Summary of the Invention

[0006] This application provides an uplink transmission method, uplink transmission device, and terminal, which can solve the problem of reduced transmission performance caused by the need for the FBE transmitting node to perform LBT for each transmission in a transmission cluster.

[0007] Firstly, an uplink transmission method is provided, the method comprising:

The first uplink transmission and the second uplink transmission are adjacent, and the interval between the first uplink transmission and the second uplink transmission is less than or equal to a first preset time. The terminal is a frame-based device (FBE).

[0009] Secondly, an uplink transmission apparatus is provided for use in a terminal, wherein the terminal is a frame-based device (FBE), and the apparatus includes:

[0010] The transmission module is used to perform channel access and / or transmission of the second uplink transmission in the uplink transmission cluster according to the transmission status of the first uplink transmission in the uplink transmission cluster, wherein the first uplink transmission and the second uplink transmission are adjacent, and the interval between the first uplink transmission and the second uplink transmission is less than or equal to a first preset time, and the terminal is a frame-based device (FBE).

[0011] Thirdly, a terminal is provided, comprising a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the method described in the first aspect.

[0012] Fourthly, a terminal is provided, including a processor and a communication interface, wherein the communication interface is used to perform channel access and / or transmission of a second uplink transmission in the uplink transmission cluster according to the transmission status of a first uplink transmission in the uplink transmission cluster, wherein the first uplink transmission and the second uplink transmission are adjacent, and the interval between the first uplink transmission and the second uplink transmission is less than or equal to a first preset time, and the terminal is a frame-based device (FBE).

[0013] Fifthly, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect.

[0014] In a sixth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being used to run programs or instructions to implement the method as described in the first aspect.

[0016] In this embodiment, the terminal performs channel access and / or transmission for a second uplink transmission in the uplink transmission cluster based on the transmission status of a first uplink transmission in the uplink transmission cluster. The first and second uplink transmissions are adjacent, and the interval between them is less than or equal to a first preset time. The terminal is a frame-based device (FBE). Thus, during continuous uplink transmission, the FBE terminal can determine the channel access mechanism before the next uplink transmission based on the transmission status of an already executed uplink transmission in an adjacent uplink transmission, and / or perform uplink transmission after channel access, or perform uplink transmission without channel access-related monitoring, thereby improving channel access and transmission performance.

The following description describes New Radio (NR) systems for illustrative purposes, and NR terminology is used in most of the following description; however, these technologies can also be applied to applications beyond NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0027] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. Terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment. Network-side equipment 12 may include access network equipment or core network equipment. Access network equipment 12 may also be referred to as radio access network equipment, radio access network (RAN), radio access network function, or radio access network unit. Access network equipment 12 may include base stations, WLAN access points, or WiFi nodes, etc. Base stations may be referred to as Node B, evolved Node B (eNB), access point, base transceiver station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home B node, home evolved B node, Transmitting Receiving Point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.In future communication systems, shared spectrum, such as unlicensed bands, can supplement licensed bands to help operators expand service capacity. To maintain consistency with NR deployments and maximize NR-based unlicensed access, unlicensed bands can operate in the 5GHz, 37GHz, and 60GHz bands. Because unlicensed bands are shared by various Radio Access Technologies (RATs), such as WiFi, radar, and LTE-Licensed-Assisted Access (LTE-LAA), in some countries or regions, their use must comply with regulations to ensure fair resource allocation for all devices. These regulations include LBT (Local Power Bypass) and Maximum Channel Occupancy Time (MCOT). When a transmitting node needs to send information, it first performs an LBT, checking the power of surrounding nodes (energy detection, ED). If the detected power is below a threshold, the channel is considered idle, and the transmitting node can then send data. Conversely, if the channel is busy, the transmission node cannot send data. The transmission node can be a base station, UE, WiFi access point (AP), etc. Once the transmission node begins transmission, the channel time occupied (COT) cannot exceed the MCOT.

[0028] FBE nodes occupy channels using a channel access mechanism based on LBT. The node that initiates a transmission sequence containing one or more consecutive transmissions is called the initiating device, and the other nodes are called responding devices. An FBE node can be an initiating device, a responding device, or support both functions simultaneously.

[0029] like Figure 2 As shown, the operational requirements for the FBE initiating node include:

[0030] 1) The set of Fixed Frame Period values ​​supported by the node is declared by the device manufacturer, and each value must be within the range of 1 to 10 ms. Transmission can only be initiated at the beginning of a Fixed Frame Period. The node can change its currently applied Fixed Frame Period, but the frequency cannot exceed once every 200 ms.

[0031] 2) Before initiating transmission at the beginning of a Fixed Frame Period, the initiating node will perform Clear Channel Assessment (CCA). If the channel is determined to be idle, transmission can begin immediately; otherwise, transmission is not permitted for the subsequent Fixed Frame Period (except for Short Control Signalling Transmissions as required by regulations). In other words, the initiating node needs to perform a one-shot LBT (Cat.2LBT) before transmission.

[0032] 3) The total duration during which the initiating node can transmit without re-estimating channel availability within a Fixed Frame Period that has already begun transmission is defined as the Channel Occupancy Time (COT). The FBE initiating node can transmit multiple times on a designated channel within the COT without performing additional CCA, as long as the time interval between adjacent transmissions does not exceed 16 μs. In other words, if the time interval between adjacent transmissions within the COT exceeds 16 μs, the FBE initiating node needs to perform additional CCA before continuing transmission after that 16 μs, and will only continue transmission if the CCA determines that the channel is idle. All time intervals between adjacent transmissions are included in the COT duration.

[0033] 4) The FBE initiating node can authorize the use of a designated channel within a certain time period in the COT to one or more associated FBE responding nodes for transmission.

[0034] 5) The COT cannot be longer than 95% of the Fixed Frame Period, and an Idle Period immediately follows the COT. The Idle Period lasts until the start of the next Fixed Frame Period. The length of the Idle Period is at least 5% of the Fixed Frame Period, and the minimum value is 100 μs.

[0035] 6) After a node correctly receives a data packet for it, it can immediately transmit the corresponding management and control frame (e.g., ACK frame) on the designated channel without performing a CCA. This node needs to ensure that these continuously transmitted frames do not exceed the maximum COT duration mentioned above.

[0036] For an FBE response node, after receiving authorization from an FBE initiating node to use a specified channel for a certain period of time, it will perform the following operations:

[0037] If an FBE responding node initiates a transmission at most 16 μs after the last authorized transmission indicated by the FBE initiating node, it does not need to perform a CCA before transmission. The last authorized transmission indicated by the FBE initiating node and the transmission initiated by the FBE responding node share the COT initiated by the FBE initiating node. Otherwise, it performs a CCA before the start of the authorized transmission period. If the channel is busy, the authorization is discarded. Otherwise, transmission can be started on the designated channel, occupying up to the remaining portion of the COT within the current Fixed Frame Period. Multiple transmissions can be started within the remaining time range, as long as the time interval between adjacent transmissions does not exceed 16 μs. The authorization is discarded after transmission is completed.

[0038] As can be seen from the above, since the channel access mechanism of the FBE terminal during continuous transmission is not defined, for example, when continuous uplink transmission includes at least one scheduled uplink transmission and at least one configured uplink transmission, and there are at least two scheduled uplink transmissions interspersed with configured uplink transmissions in continuous uplink transmission, and / or there are at least two configured uplink transmissions interspersed with scheduled uplink transmissions in continuous uplink transmission, how to perform channel listening and channel access according to the LBT channel access mechanism before sending the scheduled uplink transmission or the configured uplink transmission is not defined in the prior art.

[0039] In this embodiment of the application, a channel access mechanism for the FBE terminal during the aforementioned continuous transmission is defined.

[0040] The uplink transmission method, uplink transmission device, and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0041] Please see Figure 3 The uplink transmission method provided in this application embodiment can be executed by a frame-based device, such as a terminal, an FBE UE, or other FBE transmitting nodes, without specific limitations. Figure 3 As shown, the uplink transmission method may include the following steps:

[0042] Step 301: The terminal performs channel access and / or transmission for the second uplink transmission in the uplink transmission cluster according to the transmission status of the first uplink transmission in the uplink transmission cluster, wherein the first uplink transmission and the second uplink transmission are adjacent, and the interval between the first uplink transmission and the second uplink transmission is less than or equal to a first preset time, and the terminal is a frame-based device (FBE).

[0043] In specific implementations, the aforementioned uplink transmission burst (UL transmission burst) can be a group of continuous uplink transmissions. A continuous uplink transmission can be understood as at least two uplink transmission sequences, and the interval between any adjacent uplink transmissions in these at least two uplink transmission sequences is less than or equal to a first preset time (e.g., 16 μs). The uplink transmissions in the uplink transmission burst can include at least one of PUSCH, PUCCH, and SRS. For ease of explanation, the following embodiments use PUSCH as an example of uplink transmission, which is not intended to be a specific limitation. For example: the UE is configured by the gNB to send a group of continuous, gapless UL transmissions; or the UE is scheduled to use one or more uplink (UL) grants to send a group of continuous, gapless UL transmissions; or the UE's continuous uplink transmissions include at least one scheduled uplink transmission and at least one configured uplink transmission; or at least two scheduled uplink transmissions are interspersed with configured uplink transmissions in the UE's continuous uplink transmissions; or at least two configured uplink transmissions are interspersed with scheduled uplink transmissions in the UE's continuous uplink transmissions. Among them, the scheduled uplink transmission is the uplink transmission based on the scheduling authorization DG, and the configured uplink transmission is the uplink transmission based on the configuration authorization CG.

[0044] The COT containing the aforementioned uplink transmission cluster can be a COT initiated by the terminal itself (UE-initiated COT) or a COT authorized and shared by network-side equipment (e.g., a base station), meaning the terminal shares a COT initiated by the network-side equipment (gNB-initiated COT). In other words, the uplink transmission cluster can be continuous uplink transmission performed by the terminal within its own initiated COT; or, the uplink transmission cluster can be continuous uplink transmission performed by the terminal within a shared COT of a network-side equipment.

[0045] In specific implementation, the uplink transmission in the aforementioned uplink transmission cluster may include scheduled uplink transmission and / or configured uplink transmission.

[0046] The scheduled uplink transmission can be defined as: the uplink transmission performed by the terminal by the network-side device through DCI scheduling. The configured uplink transmission can be the uplink transmission configured by the network-side device for the terminal.

[0047] For scheduled uplink transmissions, the terminal accesses the channel according to the channel access type indicated in the DCI that schedules the uplink transmission, and sends the scheduled uplink transmission after successful channel access; otherwise, it does not send the scheduled uplink transmission.

[0048] The gNB and UE can use different FFP periods and / or different FFP start positions. If the UE wants to perform uplink transmission, it can perform LBT during its own FFP idle period. If it detects that the channel is empty, it will initiate COT to perform uplink transmission. Simultaneously, the UE's COT can also be shared with the base station. The base station can send downlink signals, such as control signals, broadcast signals, and data, to the UE that initiated the COT or other UEs within the shared COT. Here, the UE's COT refers to the COT initiated by the UE. Of course, the base station can also share its own initiated COT with the UE, allowing the UE to send uplink signals within the base station's shared COT.

[0049] For example, the correspondence between the index indicated in the DCI and the corresponding channel access type for the scheduled uplink transmission is shown in Table 1 below:

[0050] Table 1

[0051]

[0052]

[0053] As shown in Table 1 above, the gNB can notify the UE to share the base station's COT or initiate COT itself by scheduling the DCI to indicate different channel access types. Furthermore, if the protocol specifies otherwise, the 9μs in Table 1 can be replaced by 16μs. That is, the protocol specifies either 16μs of listening within 25μs or 16μs of listening as specified in the protocol.

[0054] In addition, for the configured uplink transmission, the terminal determines the channel access method of the configured uplink transmission according to the initiator of the current COT before sending the uplink transmission, so as to realize channel access.

[0055] However, in cases where the same uplink transmission cluster of an FBE terminal includes multiple consecutive scheduled uplink transmissions, multiple consecutive configured uplink transmissions, or both scheduled and configured uplink transmissions, for example, if the first uplink transmission is a configured uplink transmission and the second uplink transmission is a scheduled uplink transmission, the terminal may perform LBT on the first uplink transmission and the second uplink transmission respectively.

[0056] The uplink transmission cluster in this application embodiment may include configured uplink transmission, or even simultaneously scheduled uplink transmission and configured uplink transmission.

[0057] In this embodiment, the channel access type of the current uplink transmission can be determined based on the transmission status of the previous uplink transmission, or the current uplink transmission can be sent directly without channel sensing to reduce the LBT frequency. For example, when two adjacent uplink transmissions are configured uplink transmission and scheduled uplink transmission, this application can determine the channel access and / or transmission mechanism of the configured uplink transmission based on the transmission status of the adjacent scheduled uplink transmission; it can also determine the channel access and / or transmission mechanism of the scheduled uplink transmission based on the transmission status of the adjacent configured uplink transmission.

[0058] Optionally, the uplink transport cluster includes at least one scheduled uplink transport and at least one configured uplink transport.

[0059] In implementation, when the aforementioned uplink transmission cluster includes at least one scheduled uplink transmission and at least one configured uplink transmission, the terminal performs channel access and / or transmission for the second uplink transmission in the uplink transmission cluster based on the transmission status of the first uplink transmission in the uplink transmission cluster. This can include the following scenarios:

[0060] Scenario 1

[0061] For a scheduled uplink transmission within a continuous uplink transmission (i.e., an uplink transmission cluster), if there are other scheduled or configured uplink transmissions preceding this transmission, and the previous transmission was successful, the terminal will not perform LBT and will directly transmit the scheduled uplink transmission.

[0062] Scenario 2

[0063] For a configured uplink transmission in a continuous uplink transmission, if there are other scheduled or configured uplink transmissions before this transmission and the previous transmission was successful, the terminal will not perform LBT and will directly transmit the configured uplink transmission.

[0064] Scenario 3

[0065] For scheduled uplink transmissions in a continuous uplink transmission, if there are other scheduled or configured uplink transmissions preceding this transmission, and the previous transmission failed, if the UE shares gNB-initiated COT, the UE will access the channel according to the channel access type indicated by the DCI corresponding to the scheduled uplink transmission.

[0066] Scenario 4

[0067] For a configured uplink transmission in a continuous uplink transmission, if there are other scheduled or configured uplink transmissions preceding the transmission and the previous transmission failed, if the UE shares gNB-initiated COT, the UE will perform at least 9us of channel sensing within 25us before the transmission.

[0068] Case 5

[0069] For scheduled uplink transmissions in continuous uplink transmissions, if there are other scheduled or configured uplink transmissions preceding this transmission, and the previous transmission failed, if the UE initiates COT itself, the UE will access the channel according to the DCI indication.

[0070] Case 6

[0071] For a configured uplink transmission in a continuous uplink transmission, if there are other scheduled or configured uplink transmissions before this transmission and the previous transmission failed, if the UE initiates COT itself, the UE will perform at least 9us of channel sensing before the transmission.

[0072] Optionally, when the uplink transport cluster contains at least two scheduled uplink transports, there is a configured uplink transport between the at least two scheduled uplink transports; and / or,

[0073] When the uplink transport cluster contains at least two configured uplink transports, there is a scheduled uplink transport between the at least two configured uplink transports.

[0074] Wherein, when the uplink transmission cluster contains at least two scheduled uplink transmissions, there is a configured uplink transmission between the at least two scheduled uplink transmissions; and / or, when the uplink transmission cluster contains at least two configured uplink transmissions, there is a scheduled uplink transmission between the at least two configured uplink transmissions. This can be understood as: the scheduled uplink transmissions and configured uplink transmissions in the uplink transmission cluster can appear alternately, that is, the interval between at least two scheduled uplink transmissions in the uplink transmission cluster can be greater than the first preset time (16μs), for example: Figure 4 As shown, DGPUSCH1, DG PUSCH2, and DG PUSCH3 are three scheduled uplink transmissions, and DG PUSCH1, DG PUSCH2, and DGPUSCH3 are not contiguous, and / or, the interval between at least two configured uplink transmissions in the uplink transmission cluster can be greater than the first preset time (16μs), for example: Figure 4 As shown, CG PUSCH1, CG PUSCH2 and CG PUSCH3 are three uplink transmissions in configuration. CG PUSCH1 is not contiguous with CG PUSCH2 and CG PUSCH3, while CG PUSCH2 and CG PUSCH3 are contiguous.

[0075] In specific implementation, the step of performing channel access and / or transmission for the second uplink transmission in the uplink transmission cluster based on the transmission status of the first uplink transmission in the uplink transmission cluster can be understood as follows: before the transmission of the second uplink transmission begins, if the first uplink transmission is successful, the second uplink transmission can proceed directly without performing channel access-related listening (e.g., LBT or CCA; for ease of explanation, LBT is used as an example in the following embodiments). If the first uplink transmission fails, LBT can be performed, and if the channel access is successfully achieved through LBT, the second uplink transmission can proceed.

[0076] In other words, the first uplink transmission is the last uplink transmission in the uplink transmission cluster before the second uplink transmission. If the first uplink transmission is successful, the terminal does not perform Listen-Before-Speak (LBT) and proceeds with the second uplink transmission. Thus, this embodiment can determine whether access channel related listening (ABS) is needed on the channel corresponding to the second uplink transmission based on the transmission status of the first uplink transmission. If listening is needed, the terminal determines whether to proceed with the second uplink transmission based on the listening results; otherwise, it can directly proceed with the second uplink transmission. This reduces the frequency of LBT, thereby reducing communication latency and improving transmission performance.

[0077] If the second uplink transmission is a scheduled uplink transmission, the DCI that schedules the uplink transmission may indicate the channel access type of the second uplink transmission.

[0078] Optionally, if the first uplink transmission is successful, the terminal does not perform LBT and performs the second uplink transmission, including:

[0079] If the second uplink transmission is a scheduled uplink transmission, then if the first uplink transmission is successful, the terminal ignores the channel access type indicated in the DCI that schedules the second uplink transmission and directly performs the second uplink transmission.

[0080] In this embodiment, if the first uplink transmission is successful, the terminal can ignore the channel access type indicated in the DCI for scheduling the second uplink transmission and directly send the second uplink transmission. This reduces resource waste and increased transmission latency caused by the terminal performing channel access-related listening processes before sending the second uplink transmission.

[0081] In the event of a failure of the first uplink transmission, the channel access mechanism prior to the second uplink transmission can be determined based on the type of the second uplink transmission and the initiator of the COT to which the uplink transmission cluster belongs.

[0082] As an optional implementation, the terminal performs channel access and / or transmission for the second uplink transmission in the uplink transmission cluster based on the transmission status of the first uplink transmission in the uplink transmission cluster, further comprising:

[0083] If the second uplink transmission is a scheduled uplink transmission, then in the event of a failure of the first uplink transmission, the terminal performs channel access according to the channel access type indicated by the DCI of the second uplink transmission.

[0084] In this embodiment, if the first uplink transmission fails, the terminal performs channel access according to the instructions in the corresponding DCI before sending the second uplink transmission, so as to reduce the probability of the second uplink transmission failing.

[0085] As another optional implementation, the terminal performs channel access and / or transmission for the second uplink transmission in the uplink transmission cluster based on the transmission status of the first uplink transmission in the uplink transmission cluster, further comprising:

[0086] If the second uplink transmission is a configured uplink transmission, then in the event of a failure of the first uplink transmission, the terminal performs channel listening for a second preset time before performing the second uplink transmission, and performs channel access based on the channel listening result.

[0087] In specific implementation, the aforementioned second preset time can be greater than or equal to 9μs or 16μs, that is, the terminal can perform channel listening for at least 9μs or 16μs before the start time of the second uplink transmission. The aforementioned channel listening for the second preset time, as well as the channel access mechanism after channel listening, and the specific listening and channel idle estimation (CCA) process will not be described in detail here.

[0088] In this embodiment, if the first uplink transmission fails, channel listening can be performed on the configured uplink transmission to be transmitted, so that if it is determined that the channel corresponding to the configured uplink transmission is idle, the configured uplink transmission can be sent.

[0089] It should be noted that after performing channel listening for a second preset time before sending the second uplink transmission, if the terminal determines that the channel corresponding to the second uplink transmission is not idle, it will not send the second uplink transmission to avoid interference with surrounding nodes. Furthermore, the uplink transmission cluster after the second uplink transmission may also include a third uplink transmission, etc. In this case, if it is determined that the channel corresponding to the second uplink transmission is not idle, the second uplink transmission can be skipped, and the third uplink transmission can be listened to and accessed accordingly; this will not be elaborated further here.

[0090] Optionally, if the second uplink transmission is a configured uplink transmission, then in the event of a failure of the first uplink transmission, the terminal performs channel listening for a second preset time before performing the second uplink transmission, and performs channel access based on the channel listening result, including:

[0091] If the second uplink transmission is a configured uplink transmission and the terminal initiates COT, then in the event that the first uplink transmission fails, the terminal performs channel listening for a second preset time before performing the second uplink transmission, and performs channel access based on the channel listening result.

[0092] If the second uplink transmission is a configured uplink transmission, and the terminal shares the COT initiated by the network-side device, then in the event of the first uplink transmission failure, the terminal performs channel listening for a second preset time within a third preset time before performing the second uplink transmission, and performs channel access based on the channel listening result.

[0093] In a specific implementation, the aforementioned third preset time can be 25μs, meaning that the terminal can perform channel listening for at least 9μs or 16μs within 25μs before the start time of the second uplink transmission.

[0094] This implementation corresponds to the channel access type index fields “2” and “3” in the DCI shown in Table 1, and will not be repeated here. The difference is that this implementation is used to perform channel listening on the configured uplink transmission, while Table 1 is used to perform channel listening on the scheduled uplink transmission according to the instructions in the DCI.

[0095] In this embodiment, the channel sniffing mechanism for the configured uplink transmission can be determined based on the initiator of the COT to which the uplink transmission cluster is located.

[0096] It should be noted that for Load Bearing Equipment (LBE) type UEs, if the gNB schedules continuous uplink transmissions via a Downlink Control Information (DCI), and the UE cannot access the uplink channel via Type 1, Type 2, or Type 2A before the transmission ends, the UE will continue to attempt channel access according to the channel access type indicated by the DCI in the next transmission. If the UE cannot access the channel via Type 2B, the UE will access the channel via Type 2A in the next transmission. This scheduled uplink transmission can also be referred to as dynamic grant UL transmission.

[0097] If the gNB schedules continuous uplink transmissions through multiple DCIs, and the UE cannot access the channel for uplink transmission through Type 1, Type 2, Type 2A, or Type 2B before the transmission ends, the UE will continue to attempt channel access according to the channel access type indicated by the DCI in the next transmission.

[0098] If the UE accesses the channel and performs uplink transmission according to any one of Type 1, Type 2, Type 2A, Type 2B or Type 2C, the UE can continue the remaining uplink transmission without performing LBT.

[0099] If the UE is configured for continuous uplink transmission, and if the UE cannot access the channel via the Type 1 channel access mechanism before the transmission ends, the UE can continue to access the channel via the Type 1 channel access mechanism in subsequent transmissions. If the UE successfully transmits any uplink channel, the UE can continue transmitting subsequent uplink transmissions without performing LBT.

[0100] If the UE accesses the channel using the Type 1 channel access mechanism and performs configured grant UL transmission, and if the base station schedules the UE to perform scheduled uplink transmission immediately after configuring uplink transmission, and if the total transmission time of both does not exceed the maximum channel occupancy time (MCOT) available for the UE to access the channel using the Type 1 channel access mechanism, then the UE will perform scheduled uplink transmission immediately after configuring grant uplink transmission.

[0101] As can be seen from the above, the current protocol only defines the channel access mechanism for LBE UEs in three scenarios: continuous scheduled uplink transmissions, continuous configured licensed transmissions, or continuous configured licensed transmissions followed immediately by continuous scheduled uplink transmissions. However, the channel access mechanism for FBE UEs during continuous transmissions is not defined.

[0102] It is worth noting that the channel access mechanism for continuous transmission of the FBE UE in the uplink transmission method provided in this application includes, but is not limited to:

[0103] 1) FBE UEs can transmit within a shared base station's COT or within their own self-initiated COT;

[0104] 2) Continuous transmission can be interleaved between configured uplink transmissions and scheduled uplink transmissions. For example, at least one scheduled uplink transmission may be interleaved between two configured uplink transmissions, or at least one configured uplink transmission may be interleaved between two scheduled uplink transmissions.

[0105] 3) The channel access type of FBE UE is shown in Table 1, which is different from the channel access type of LBE UE.

[0106] Therefore, the channel access mechanism for LBE UE during continuous transmission is not applicable to the channel access mechanism for FBE UE during continuous transmission. However, this application proposes a channel access mechanism for FBE UE during continuous transmission.

[0107] For ease of explanation, as follows Figure 4 As shown, taking an application scenario as an example, the uplink transmission method provided in this application embodiment will be illustrated:

[0108] like Figure 4 In the application scenario shown, before the start of FFP, i.e., within the idle period of the previous FFB immediately adjacent to the target period 41 of the current FFP, the terminal performs LBT or CCA to access the channel based on the channel sensing results and initiates the corresponding COT. The uplink transmission cluster within this COT includes three scheduled uplink transmissions: DG PUSCH1, DG PUSCH2, and DG PUSCH3, and three configured uplink transmissions: CG PUSCH1, CG PUSCH2, and CG PUSCH3. The time-domain order of each uplink transmission is: DG PUSCH1, CG PUSCH1, DG PUSCH2, CG PUSCH2, CG PUSCH3, and DG PUSCH3.

[0109] Example 1

[0110] For uplink transmissions scheduled within an uplink transmission cluster, for example: Figure 4 The DG PUSCH2 and DGPUSCH3 shown have previously been transmitted via other uplink transmissions, namely CG PUSCH1 and CG PUSCH3. In this embodiment, if CG PUSCH1 is successfully transmitted, the terminal ignores the channel access type indicated in the DCI of DG PUSCH2 and directly transmits DG PUSCH2. If CG PUSCH3 is successfully transmitted, the terminal ignores the channel access type indicated in the DCI of DG PUSCH3 and directly transmits DG PUSCH3.

[0111] Correspondingly, for the uplink transmission configured in the uplink transmission cluster, for example: Figure 4The CGPUSCH1, CG PUSCH2, or CG PUSCH3 shown represent previous uplink transmissions, corresponding to DG PUSCH1, DGPUSCH2, and CG PUSCH2, respectively. If DG PUSCH1 is successfully transmitted, the terminal directly transmits CG PUSCH1 without performing an uplink passthrough (LBT). If DGPUSCH2 is successfully transmitted, the terminal directly transmits CG PUSCH2 without performing an LBT. After CG PUSCH2 is transmitted, the terminal can directly transmit CG PUSCH3.

[0112] Example 2

[0113] Uplink transmissions scheduled for uplink transmission clusters, for example: Figure 4 The DG PUSCH2 and DGPUSCH3 shown have previously had other uplink transmissions, namely CG PUSCH1 and CG PUSCH3, and the terminals share the gNB-initiated COT. If the CG PUSCH1 transmission fails, the terminal performs LBT according to the channel access type indicated in the DCI of the DG PUSCH2 scheduler. If the channel is empty, DG PUSCH2 is transmitted; if the channel is busy, the transmission of DGPUSCH2 is skipped. Similarly, if the CG PUSCH3 transmission fails, the terminal performs LBT according to the channel access type indicated in the DCI of the DG PUSCH3 scheduler. If the channel is empty, DG PUSCH3 is transmitted; if the channel is busy, the transmission of DGPUSCH3 is skipped. The channel access type indicated in the DCI can be the channel access type corresponding to index 2 in Table 1, i.e., listening for 9μs or 16μs within a 25μs interval.

[0114] Correspondingly, for the uplink transmission configured in the uplink transmission cluster, for example: Figure 4The CGPUSCH1, CG PUSCH2, and CG PUSCH3 shown are preceded by other uplink transmissions, corresponding to DG PUSCH1, DGPUSCH2, and CG PUSCH2 respectively, and the terminals share the gNB-initiated COT. If the DG PUSCH1 transmission fails, the terminal performs LBT within 25µs before the CG PUSCH1 transmission, where the second preset time, i.e., the sensing slot duration, is at least 9µs or 16µs. If the channel is empty, CG PUSCH1 is transmitted; if the channel is busy, the CGPUSCH1 transmission is skipped. Similarly, if the DG PUSCH2 transmission fails, the terminal performs LBT within 25µs before the CG PUSCH2 transmission, where the sensing slot duration is at least 9µs or 16µs. If the channel is empty, CG PUSCH2 is transmitted; if the channel is busy, the CG PUSCH2 transmission is skipped. Similarly, if CG PUSCH2 transmission fails, at least 9us or 16us of channel listening will be performed within 25us before CG PUSCH3 transmission, and the transmission of CG PUSCH3 will be determined based on the listening results.

[0115] Example 3

[0116] For uplink transmissions scheduled within an uplink transmission cluster, for example: Figure 4 As shown, DG PUSCH2 and DGPUSCH3 have previous uplink transmissions, namely CG PUSCH1 and CG PUSCH3, and the terminal performs these transmissions within its own initiated COT (i.e., UE-initiated COT). If CG PUSCH1 transmission fails, the terminal performs LBT according to the channel access type indicated in the DCI of DG PUSCH2. If the channel is empty, DG PUSCH2 is transmitted; if the channel is busy, the transmission of DG PUSCH2 is skipped. Similarly, if CG PUSCH3 transmission fails, the UE performs LBT according to the channel access type indicated in the DCI of DG PUSCH3. If the channel is empty, DG PUSCH3 is transmitted; if the channel is busy, the transmission of DG PUSCH3 is skipped. The channel access type indicated by the DCI can be the channel access type corresponding to index 3 in Table 1, i.e., listening for 9μs or 16μs as specified in the protocol.

[0117] Uplink transmissions configured within the uplink transmission cluster, for example: Figure 4The CG PUSCH1, CGPUSCH2, and CG PUSCH3 shown in the diagram have been preceded by other uplink transmissions, corresponding to DG PUSCH1, DG PUSCH2, and CGPUSCH2 respectively, and the terminal performs the transmissions within its own initiated COT (i.e., UE-initiated COT). If the DG PUSCH1 transmission fails, the terminal performs an LBT before transmitting CG PUSCH1, where the sensing slot duration is at least 9µs or 16µs, and this sensing slot is immediately adjacent to CG PUSCH1. If the channel is empty, CG PUSCH1 is transmitted; if the channel is busy, the transmission of CG PUSCH1 is skipped. Similarly, if the DG PUSCH2 transmission fails, the terminal performs an LBT before transmitting CG PUSCH2, where the sensing slot duration is at least 9µs or 16µs, and this sensing slot is immediately adjacent to CG PUSCH2. If the channel is empty, CG PUSCH2 is transmitted; if the channel is busy, CG PUSCH2 transmission is skipped. This continues until CG PUSCH2 transmission fails. The terminal then listens for at least 9µs or 16µs before transmitting CG PUSCH3, determining whether to transmit CG PUSCH3 based on the listening result.

[0118] In this embodiment, the terminal performs channel access and / or transmission for a second uplink transmission in the uplink transmission cluster based on the transmission status of a first uplink transmission in the uplink transmission cluster. The first and second uplink transmissions are adjacent, and the interval between them is less than or equal to a first preset time. The terminal is a frame-based device (FBE). Thus, during continuous uplink transmission, the FBE terminal can determine the channel access mechanism before the next uplink transmission based on the transmission status of an already executed uplink transmission in an adjacent uplink transmission, and / or perform uplink transmission after channel access, or perform uplink transmission without channel access, thereby improving channel access and transmission performance.
