Description

Technical Field

The application belongs to the technical field of communication, and particularly relates to an uplink transmission method, an uplink transmission device and a terminal.

Background

The transmission/reception timing of the frame-based device (Frame Based Equipment, FBE) adopts a periodic structure, the period of which is a fixed frame period (Fixed Frame Period, FFP).

The FBE node occupies the channel using a listen before talk (Listen Before Talk, LBT) based channel access mechanism and starts transmission at the start of a certain FFP after accessing the channel.

Specifically, the FBE originating node needs to perform channel idle estimation (Clear Channel Assess, CCA) before starting transmission at the starting time of a certain FFP, and if it determines to be idle, it may immediately transmit, otherwise, it is not allowed to transmit for the duration of the next FFP. And the FBE originating node may transmit multiple times on the designated channel without performing additional CCA within the channel occupancy time (Channel Occupation Timer, COT) of the FFP that has begun to transmit, as long as the time interval between adjacent ones of these transmissions does not exceed 16 mus.

However, in one transmission cluster, the FBE transmitting node needs to perform LBT for each transmission, which affects transmission performance.

The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation, 6G) communication system.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc.. Note that, the specific type of the terminal 11 is not limited in the embodiment of the present application. The network-side device 12 may comprise an access network device or a core network device, wherein the access network device 12 may also be referred to as a radio access network device, a radio access network (Radio Access Network, RAN), a radio access network function or a radio access network element. Access network device 12 may include a base station, a WLAN access point, a WiFi node, or the like, which may be referred to as a node B, an evolved node B (eNB), an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a home node B, a home evolved node B, a transmission and reception point (Transmitting Receiving Point, TRP), or some other suitable terminology in the art, and the base station is not limited to a particular technical vocabulary so long as the same technical effect is achieved, and it should be noted that in the embodiments of the present application, only a base station in an NR system is described as an example, and the specific type of the base station is not limited. In future communication systems, the shared spectrum, such as unlicensed band, may be used as a supplement to licensed band (licensed band) to help operators expand services. To keep pace with NR deployment and maximize as much as possible unlicensed access based on NR, unlicensed bands may operate in the 5GHz,37GHz and 60GHz bands. Since unlicensed frequency bands are shared by multiple radio access technologies (Radio Access Technologys, RATs), for example: wiFi, radar, licensed-Assisted Access (LTE-LAA) for LTE, etc., so in some countries or regions, unlicensed bands must meet rules (regulations) when used to ensure that all devices can use the resource fairly, for example: LBT, maximum channel occupation time (Maximum Channel Occupancy Time, MCOT), etc. When the transmission node needs to transmit information, it needs to make LBT first, perform power detection (ED) on surrounding nodes, and when the detected power is lower than a threshold, consider the channel as empty (idle), and the transmission node can transmit. Otherwise, the channel is considered as busy, and the transmission node cannot transmit. The transmission node may be a base station, a UE, a WiFi Access Point (AP), or the like. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT.

The FBE node occupies a channel using an LBT-based channel access mechanism. The node in which the transmission sequence comprising one or more consecutive transmissions is initiated is called the initiating node (Initiating Device), the other nodes being called responding nodes (Responding Device). The FBE node may be an initiating node, a responding node, or support both node functions.

As shown in fig. 2, the operational requirements of the FBE originating node include:

1) The Fixed Frame Period set of values supported by the node is declared by the device manufacturer, and each value requirement lies in the range of 1-10 ms. The transmission may only be initiated at the beginning of a certain Fixed Frame Period. The node may change Fixed Frame Period of its current application, but it cannot be more frequent than once a 200 ms.

2) Before starting the transmission at the beginning of a certain Fixed Frame Period, the initiating node will perform a channel idle estimation (Clear Channel Assess, CCA), if it decides to be idle, it can transmit immediately, otherwise it is not allowed to transmit for the immediately following Fixed Frame Period period (except for the short control signaling transmission (Short Control Signalling Transmissions) specified by regulatory requirements). That is, the originating node needs to do a one-shot LBT (one-shot LBT), i.e., cat.2lbt, before transmitting.

3) Within a certain started transmission Fixed Frame Period, the total duration that the corresponding originating node can transmit without re-estimating the availability of the channel is defined as the channel occupancy time (Channel Occupancy Time, COT). The FBE originating node may transmit multiple times on a designated channel within the COT without performing additional CCA as long as the time interval between adjacent ones of these transmissions does not exceed 16 mus. In other words, if the time interval between adjacent transmissions within the COT exceeds 16 μs, the FBE initiating node needs to perform an additional CCA before continuing the transmission after the 16 μs, and continues the transmission only when the CCA determines that the channel is idle. Wherein the time intervals between all adjacent transmissions are counted in the COT duration.

4) The FBE originating node may grant usage rights for specified channels for certain periods of time within the COT to one or more associated FBE responding nodes for transmission.

5) The COT cannot be longer than 95% of Fixed Frame Period and immediately follows the COT by an Idle Period (Idle Period) which is not ended until the beginning of the next Fixed Frame Period, such that the Idle Period is at least 5% of Fixed Frame Period and has a minimum of 100 mus.

6) A node may transmit a management and control frame (e.g., an ACK frame) corresponding to a data packet on a designated channel immediately after correctly receiving the data packet for it without CCA. This node needs to ensure that these consecutively transmitted frames cannot exceed the maximum COT duration mentioned above.

For the FBE responding node, after receiving the usage grant of a specified channel by a certain FBE originating node for a certain period of time, it will perform the following operations:

the FBE responding node does not need to perform CCA before transmitting if transmitting after the FBE originating node indicates that the last transmission of grant is completed by at most 16 μs, wherein the last transmission of grant and the transmission initiated by the FBE responding node are indicated by the FBE originating node to share the COT initiated by the FBE originating node; otherwise, the CCA is executed before the start of the authorized transmission period, if the channel is judged to be busy, the authorization is discarded, otherwise, the transmission can be started on the appointed channel, the residual part of COT in the current Fixed Frame Period can be occupied at most, the transmission can be started for a plurality of times within the time range of the residual part, as long as the time interval of the adjacent transmission is not more than 16 mu s, and the authorization is discarded after the transmission is finished.

From the above, it can be seen that, since the channel access mechanism of the FBE terminal in continuous transmission is not defined, for example: the 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 with intervening configured uplink transmissions in the continuous uplink transmission, and/or how to perform channel interception and channel access according to the LBT channel access mechanism before sending the scheduled uplink transmission or sending the configured uplink transmissions when there are at least two configured uplink transmissions with intervening configured uplink transmissions in the continuous uplink transmission, which is not defined in the prior art.

In the embodiment of the present application, a channel access mechanism is defined when the FBE terminal performs the continuous transmission.

The uplink transmission method, the uplink transmission device and the terminal provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by means of some embodiments and application scenarios thereof.

Referring to fig. 3, an uplink transmission method provided in the embodiment of the present application may be a frame-based device, for example: the terminal, FBE UE, or other FBE transmitting node is not particularly limited herein. As shown in fig. 3, the uplink transmission method may include the steps of:

Step 301, a terminal performs channel access and/or transmission on a second uplink transmission in an uplink transmission cluster according to a transmission condition of a first uplink transmission in the uplink transmission cluster, where the first uplink transmission is adjacent to the second uplink transmission, and an 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.

In a specific implementation, the uplink transmission cluster (UL transmission burst) may be a set of continuous uplink transmissions, where the continuous uplink transmission may be understood as at least two uplink transmission sequences, an interval between any adjacent uplink transmissions in the at least two uplink transmission sequences is less than or equal to a first preset time (for example, 16 μs), and the uplink transmission in the uplink transmission cluster may include at least one of PUSCH, PUCCH and SRS, and for convenience of explanation, in the following embodiments, the uplink transmission is exemplified by PUSCH, which is not limited specifically herein. For example: the UE is configured by the gNB to send a set of consecutive UL transmissions without gaps; or the UE is scheduled to transmit a set of consecutive, non-spaced UL transmissions using one or more Uplink (UL) grants; or the continuous uplink transmission of the UE comprises at least one scheduled uplink transmission and at least one configured uplink transmission; or there are at least two uplink transmissions of the intermediate alternate configuration of scheduled uplink transmissions in the continuous uplink transmission of the UE; or there are at least two uplink transmissions configured in the continuous uplink transmission of the UE interspersed with scheduled uplink transmissions. The uplink transmission of the scheduling is uplink transmission based on the scheduling grant DG, and the uplink transmission of the configuration is uplink transmission based on the configuration grant CG.

The COT where the uplink transmission cluster is located may be a COT (UE-initiated COT) initiated by the terminal, or may be a COT authorized to be shared by a network side device (e.g., a base station), that is, the terminal shares a COT (gNB-initiated COT) initiated by the network side device. In other words, the uplink transmission cluster may be continuous uplink transmission performed by the terminal in the COT initiated by the terminal; or, the uplink transmission cluster may be continuous uplink transmission performed by the terminal in the COT of the shared network side device.

In a specific implementation, the uplink transmission in the uplink transmission cluster may include a scheduled uplink transmission and/or a configured uplink transmission.

Wherein, the scheduled uplink transmission may be expressed as: and the network side equipment schedules the uplink transmission of the terminal through the DCI. The configured uplink transmission may be uplink transmission performed by the network side device configuring the terminal.

And for the scheduled uplink transmission, the terminal performs channel access according to the channel access type indicated in the DCI for scheduling the uplink transmission, and after the channel access is successful, the scheduled uplink transmission is sent, otherwise, the scheduled uplink transmission is not sent.

The gNB and the UE may employ different FFP periods and/or different FFP start positions, respectively. If the UE wants to perform uplink transmission, LBT may be performed in the idle period of its FFP, and if it is detected that the channel is empty, it initiates COT to perform uplink transmission. Meanwhile, the COT of the UE can be shared to the base station, and the base station can send downlink signals to the UE initiating the COT or other UEs in the shared COT, for example: control signals, broadcast signals, data, etc. The COT of the UE is the COT initiated by the UE, and the base station can share the COT initiated by the base station to the UE so that the UE can send uplink signals in the COT shared by the base station.

For example: for scheduled uplink transmission, the corresponding conditions of the index indicated in the corresponding DCI and the corresponding channel access type are shown in table 1 below:

TABLE 1

As can be seen from table 1 above, the gNB may inform the UE of the co of the shared base station or itself initiate the co by scheduling DCI indicating a different channel access type. In addition, if the protocol is otherwise agreed, 9 μs in Table 1 may be replaced by 16 μs. I.e. protocol-specified interception of 16 mus within 25 mus or protocol-specified interception of 16 mus.

In addition, for the configured uplink transmission, the terminal determines a channel access mode of the configured uplink transmission according to an initiator of the current COT before sending the uplink transmission, so as to realize channel access.

However, in the same uplink transmission cluster of the FBE terminal, the same uplink transmission cluster includes a plurality of consecutive scheduled uplink transmissions, a plurality of consecutive configured uplink transmissions, and uplink transmissions including both scheduled uplink transmissions and configured uplink transmissions, for example: if the first uplink transmission is configured uplink transmission, and the second uplink transmission is scheduled uplink transmission, the terminal may perform LBT on the first uplink transmission and the second uplink transmission respectively.

The uplink transmission cluster in the embodiment of the present application may include configured uplink transmissions, and even include both scheduled uplink transmissions and configured uplink transmissions.

In this embodiment of the present application, the channel access type of the current uplink transmission can be determined according to the transmission condition of the previous uplink transmission, or the current uplink transmission can be directly sent without channel interception, so as to reduce the LBT frequency, for example: when two adjacent uplink transmissions are configured uplink transmissions and scheduled uplink transmissions respectively, the method and the device can determine a channel access and/or transmission mechanism of the configured uplink transmissions according to transmission conditions of the adjacent scheduled uplink transmissions; the channel access and/or transmission mechanism of the scheduled uplink transmission can also be determined according to the transmission condition of the adjacent configured uplink transmission.

Optionally, the uplink transmission cluster includes at least one scheduled uplink transmission and at least one configured uplink transmission.

In an implementation, when the 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 on the second uplink transmission in the uplink transmission cluster according to a transmission condition of the first uplink transmission in the uplink transmission cluster, which may include the following cases:

case one

For scheduled uplink transmission in continuous uplink transmission (i.e. uplink transmission cluster), if there are other scheduled or configured uplink transmissions before the transmission and the previous transmission is successful, the terminal does not make LBT and directly transmits the scheduled uplink transmission.

Case two

For the configured uplink transmission in the continuous uplink transmission, if other scheduled or configured uplink transmission exists before the transmission and the last transmission is successful, the terminal does not make LBT, and directly transmits the configured uplink transmission.

Case three

For scheduled uplink transmission in continuous uplink transmission, if other scheduled or configured uplink transmission exists before the transmission and the last transmission is unsuccessful, if the UE shares the gNB-initiated COT, the UE performs channel access according to the channel access type indicated by DCI corresponding to the scheduled uplink transmission.

Case four

For a configured uplink transmission in a continuous uplink transmission, if the transmission is preceded by another scheduled or configured uplink transmission and the last transmission was unsuccessful, if the UE shares the gNB-initiated COT, the UE does channel listening (sending) for at least 9us within 25us before the transmission.

Case five

For scheduled uplink transmission in continuous uplink transmission, if other scheduled or configured uplink transmission exists before the transmission, and the last transmission is unsuccessful, if the UE initiates COT by itself, the UE performs channel access according to DCI indication.

Case six

For a configured uplink transmission in a continuous uplink transmission, if the transmission is preceded by another scheduled or configured uplink transmission and the last transmission is unsuccessful, if the UE itself initiates the COT, the UE does channel listening (sending) for at least 9us before the transmission.

Optionally, when the uplink transmission cluster includes at least two scheduled uplink transmissions, there is a configured uplink transmission between the at least two scheduled uplink transmissions; and/or the number of the groups of groups,

when the uplink transmission cluster includes at least two configured uplink transmissions, there is a scheduled uplink transmission between the at least two configured uplink transmissions.

When the uplink transmission cluster comprises at least two scheduled uplink transmissions, configured uplink transmissions exist between the at least two scheduled uplink transmissions; and/or when the uplink transmission cluster includes at least two configured uplink transmissions, there is a scheduled uplink transmission between the at least two configured uplink transmissions, which can be understood as: scheduled uplink transmissions and configured uplink transmissions in the uplink transmission cluster may occur in an interleaved manner, i.e. the interval between at least two scheduled uplink transmissions in the uplink transmission cluster may be greater than the first preset time (16 mus), for example: as shown in fig. 4, DG PUSCH1, DG PUSCH2 and DG PUSCH3 are 3 scheduled uplink transmissions, and there is a discontinuity between DG PUSCH1, DG PUSCH2 and DG PUSCH3, and/or an interval between uplink transmissions configured by at least two of the uplink transmission clusters may be greater than the first preset time (16 μs), for example: as shown in fig. 4, CG PUSCH1, CG PUSCH2, and CG PUSCH3 are uplink transmissions of 3 configurations, and CG PUSCH1 is discontinuous with CG PUSCH2 and CG PUSCH3, respectively, while CG PUSCH2 and CG PUSCH3 are continuous.

In a specific implementation, the performing, according to the transmission condition of the first uplink transmission in the uplink transmission cluster, channel access and/or transmission on the second uplink transmission in the uplink transmission cluster may be understood as: before the second uplink transmission starts, if the first uplink transmission is successful, the second uplink transmission may be directly performed without channel access-related interception (e.g., LBT or CCA, for convenience of explanation, LBT is taken as an example in the following embodiments). If the first uplink transmission fails, LBT can be performed, and the second uplink transmission is performed under the condition that the channel is successfully accessed through the LBT.

That is, the first uplink transmission is the last uplink transmission before the second uplink transmission in the uplink transmission cluster, and in case that the first uplink transmission is successful, the terminal does not listen before talk LBT and performs the second uplink transmission. In this way, the embodiment of the application can determine whether to need to monitor the channel corresponding to the second uplink transmission in relation to the access channel according to the transmission condition of the first uplink transmission, determine whether to perform the second uplink transmission according to the monitoring result when the monitoring is needed, and directly perform the second uplink transmission when the monitoring is not needed, so that the frequency of LBT can be reduced, thereby reducing the communication delay and achieving the effect of improving the transmission performance.

If the second uplink transmission is scheduled uplink transmission, the DCI scheduling the uplink transmission may indicate a channel access type of the second uplink transmission.

Optionally, the performing, by the terminal, the LBT and the second uplink transmission without the first uplink transmission being successful includes:

if the second uplink transmission is scheduled uplink transmission, under the condition that the first uplink transmission is successful, the terminal ignores the channel access type indicated in the DCI for scheduling the second uplink transmission, and directly performs the second uplink transmission.

In this embodiment, if the first uplink transmission is successful, the terminal may ignore the channel access type indicated in the DCI for scheduling the second uplink transmission, and directly send the second uplink transmission. Therefore, the problems of resource waste and increased transmission delay caused by the processes of channel access related interception and the like before the terminal sends the second uplink transmission can be reduced.

Under the condition that the first uplink transmission fails, a channel access mechanism before the second uplink transmission can be determined according to the type of the second uplink transmission and information such as an initiator of the COT where the uplink transmission cluster is located.

As an optional implementation manner, the terminal performs channel access and/or transmission on the second uplink transmission in the uplink transmission cluster according to the transmission condition of the first uplink transmission in the uplink transmission cluster, and further includes:

if the second uplink transmission is scheduled uplink transmission, under the condition that the first uplink transmission fails, the terminal performs channel access according to a channel access type indicated by DCI of the second uplink transmission.

In this embodiment, if the first uplink transmission fails, the terminal performs channel access according to an instruction in the corresponding DCI before sending the second uplink transmission, so as to reduce the probability of failure of the second uplink transmission.

As another optional implementation manner, the terminal performs channel access and/or transmission on the second uplink transmission in the uplink transmission cluster according to the transmission condition of the first uplink transmission in the uplink transmission cluster, and further includes:

if the second uplink transmission is configured uplink transmission, under the condition that the first uplink transmission fails, the terminal performs channel interception for a second preset time before performing the second uplink transmission, and performs channel access according to the channel interception result.

In an implementation manner, the second preset time may be greater than or equal to 9 μs or 16 μs, that is, the terminal may perform channel interception of at least 9 μs or 16 μs before the start time of the second uplink transmission, and the channel interception performed for the second preset time, and a channel access mechanism after the channel interception, and specific interception and channel idle estimation CCA processes are not described herein.

In this embodiment, when the first uplink transmission fails, the channel interception in response to the configured uplink transmission to be transmitted may be performed, so that when it is determined that the channel corresponding to the configured uplink transmission is idle, the configured uplink transmission may be transmitted.

After channel interception for a second preset time is performed before the terminal sends the second uplink transmission, if it is determined that the channel corresponding to the second uplink transmission is not in an idle state, the terminal does not send the second uplink transmission, so that interference to surrounding nodes is avoided. Further, after the second uplink transmission, the uplink transmission cluster may further include a third uplink transmission, and at this time, if it is determined that the channel corresponding to the second uplink transmission is not in an idle state, the second uplink transmission may be skipped, and the third uplink transmission is subjected to corresponding channel interception and access, which is not described herein.

Optionally, if the second uplink transmission is configured uplink transmission, in the case that the first uplink transmission fails, the terminal performs channel interception for a second preset time before performing the second uplink transmission, and performs channel access according to the channel interception result, where the method includes:

if the second uplink transmission is configured uplink transmission and the terminal initiates COT, under the condition that the first uplink transmission fails, the terminal monitors a channel for a second preset time before the second uplink transmission, and performs channel access according to the channel monitoring result;

If the second uplink transmission is configured uplink transmission and the terminal shares the COT initiated by the network side device, under the condition that the first uplink transmission fails, the terminal performs channel interception of the second preset time within a third preset time before the second uplink transmission, and performs channel access according to the channel interception result.

In a specific implementation, the third preset time may be 25 μs, that is, the terminal may perform channel listening for at least 9 μs or 16 μs within 25 μs before the start time of the second uplink transmission.

The present embodiment corresponds to the channel access type index fields "2" and "3" in the DCI shown in table 1, and is not described herein, except that the present embodiment is used for channel interception of configured uplink transmission, and table 1 is used for channel interception of scheduled uplink transmission according to an indication in the DCI.

In this embodiment, the channel interception mechanism for the configured uplink transmission may be determined according to the initiator of the COT where the uplink transmission cluster is located.

For a UE of a load-based device (Load Bearing Equipment, LBE) Type, if the gNB schedules continuous uplink transmission by using one downlink control information (Downlink Control Information, DCI), and if the UE cannot perform uplink transmission by using a Type1, type2 or Type2A access channel before the transmission ends, the UE continues to attempt channel access according to the channel access Type indicated by the DCI at the next transmission. If the UE cannot transmit through the Type2B access channel, the UE accesses the channel according to the Type2A at the next transmission. Wherein the scheduled uplink transmission may also be referred to as a dynamic grant uplink transmission (dynamic grant UL transmission).

If the gNB schedules continuous uplink transmission through a plurality of DCIs, if the UE cannot perform uplink transmission through a Type1, type2A or Type2B access channel before the transmission is finished, the UE continues to attempt channel access according to the channel access Type indicated by the DCIs in the next transmission.

If the UE accesses the channel and performs uplink transmission according to any one of Type1, type2A, type B, or Type 2C, the UE may continue the remaining uplink transmission without LBT.

If the UE is configured with a continuous uplink transmission, the UE may continue to access the channel through the Type1 channel access mechanism in a subsequent transmission if the UE cannot access the channel through the Type1 channel access mechanism before the transmission ends. If the UE successfully transmits any uplink channel, the UE can continue to transmit the subsequent uplink transmission without LBT.

If the UE adopts the Type1 channel access mechanism to access the channel and perform configured authorized uplink transmission (configured grant UL transmission), if the base station schedules uplink transmission (scheduled UL transmission) that the UE immediately schedules after configuring the uplink transmission, if the total transmission duration of the two transmissions does not exceed the Maximum Channel Occupation Time (MCOT) available for the UE to access the channel by adopting the Type1 channel access mechanism, the UE immediately performs scheduled uplink transmission after configuring the authorized uplink transmission.

From the above, the present protocol is defined only for the channel access machine of the LBE UE in three cases of continuous scheduled uplink transmission under the LBE channel access mechanism, continuous configured grant transmission, or continuous scheduled uplink transmission immediately after the continuous configured grant transmission. In the FBE channel access mechanism, the channel access mechanism when the FBE UE continuously transmits is not defined.

It is noted that, the channel access mechanism in the continuous transmission of the FBE UE in the uplink transmission method provided in the embodiment of the present application includes, but is not limited to:

1) The FBE UE may transmit within the COT of the shared base station or within the COT initiated by itself;

2) The successive transmissions may occur as configured uplink transmissions and as scheduled uplink transmission interlaces, for example: at least one scheduled uplink transmission is interspersed between two configured uplink transmissions, or at least one configured uplink transmission is interspersed between two scheduled uplink transmissions;

3) The channel access type of the FBE UE is shown in table 1, and is different from that of the LBE UE.

Therefore, the channel access mechanism of the LBE UE at the time of continuous transmission is not applicable to the channel access mechanism of the FBE UE at the time of continuous transmission. The embodiment of the application provides a channel access mechanism of the FBE UE in continuous transmission.

For convenience of explanation, taking an application scenario as an example as shown in fig. 4, an uplink transmission method provided in the embodiment of the present application is illustrated:

in the application scenario shown in fig. 4, before the FFP starts, that is, the idle period of the previous FFB is immediately adjacent to the target period 41 of the current FFP, the terminal performs LBT or CCA to perform channel access according to the channel interception result, and initiates a corresponding COT, where an uplink transmission cluster in the COT includes 3 scheduled uplink transmissions: DG PUSCH1, DG PUSCH2 and DG PUSCH3, and 3 configured uplink transmissions: CG PUSCH1, CG PUSCH2, and CG PUSCH3. And the time domain sequence of each uplink transmission is respectively as follows: DG PUSCH1, CG PUSCH1, DG PUSCH2, CG PUSCH3, and DG PUSCH3.

Example 1

For scheduled uplink transmissions in an uplink transmission cluster, for example: DG PUSCH2 and DG PUSCH3 as shown in fig. 4, which were preceded by other uplink transmissions, CG PUSCH1, CG PUSCH3, respectively. In the embodiment of the present application, if CG PUSCH1 is successfully transmitted, the terminal ignores channel access type indicated in DCI for scheduling DG PUSCH2 and directly transmits DG PUSCH2. If CG PUSCH3 is successfully transmitted, the terminal ignores channel access type indicated in DCI for scheduling DG PUSCH3, and directly transmits DG PUSCH3.

Correspondingly, for configured uplink transmissions in the uplink transmission cluster, for example: CG PUSCH1, CG PUSCH2, or CG PUSCH3, as shown in fig. 4, which were preceded by other uplink transmissions, correspond to DG PUSCH1, DG PUSCH2, and CG PUSCH2, respectively. If the DG PUSCH1 is successfully transmitted, the terminal does not make LBT to directly transmit the CG PUSCH1. If the DG PUSCH2 is successfully transmitted, the terminal does not make LBT to directly transmit the CG PUSCH2. After the CG PUSCH2 is transmitted, the terminal may directly transmit CG PUSCH3.

Example two

Scheduled uplink transmissions for an uplink transmission cluster, such as: DG PUSCH2 and DG PUSCH3 as shown in fig. 4, which were preceded by other uplink transmissions, CG PUSCH1, CG PUSCH3, respectively, and the terminals share the gNB-initiated COT. If CG PUSCH1 transmission is unsuccessful, the terminal performs LBT according to channel access type indicated in DCI scheduling DG PUSCH2, if the channel is empty, DG PUSCH2 is transmitted, and if the channel is busy, transmission of DG PUSCH2 is skipped. Similarly, if CG PUSCH3 transmission is unsuccessful, the terminal performs LBT according to channel access type indicated in DCI for scheduling DG PUSCH3, if the channel is empty, DG PUSCH3 is transmitted, and if the channel is busy, transmission of DG PUSCH3 is skipped. The channel access type indicated by DCI may be the channel access type corresponding to index 2 in table 1, i.e. listening for 9 μs or 16 μs in 25 μs.

Correspondingly, for configured uplink transmissions in the uplink transmission cluster, for example: CG PUSCH1, CG PUSCH2, or CG PUSCH3 as shown in fig. 4, which were preceded by other uplink transmissions, correspond to DG PUSCH1, DG PUSCH2, and CG PUSCH2, respectively, and the terminals share the gNB-initiated COT. If DG PUSCH1 transmission is unsuccessful, the terminal performs LBT within 25us before CG PUSCH1 transmission, where the second preset time, i.e. the listening slot length (sensing slot duration), is at least 9us or 16us. And if the channel is empty, the CG PUSCH1 is transmitted, and if the channel is busy, the transmission of the CG PUSCH1 is skipped. Similarly, if DG PUSCH2 transmission is unsuccessful, the terminal performs LBT within 25us before CG PUSCH2 transmission, where the listening slot length is at least 9us or 16us. And if the channel is empty, the CG PUSCH2 is transmitted, and if the channel is busy, the transmission of the CG PUSCH2 is skipped. And similarly, if the CG PUSCH2 transmission is unsuccessful, channel interception is carried out for at least 9us or 16us within 25us before the CG PUSCH3 transmission, and whether the CG PUSCH3 is transmitted is determined according to interception results.

Example III

For scheduled uplink transmissions in an uplink transmission cluster, for example: DG PUSCH2 and DG PUSCH3 as shown in fig. 4, they were preceded by other uplink transmissions, CG PUSCH1, CG PUSCH3, respectively, and the terminal transmits within its own initiated COT (i.e., UE-initiated COT). If CG PUSCH1 transmission is unsuccessful, the terminal performs LBT according to channel access type indicated in DCI scheduling DG PUSCH2, if the channel is empty, DG PUSCH2 is transmitted, and if the channel is busy, transmission of DG PUSCH2 is skipped. Similarly, if CG PUSCH3 transmission is unsuccessful, the UE performs LBT according to channel access type indicated in DCI scheduling DG PUSCH3, if the channel is empty, DG PUSCH3 is transmitted, and if the channel is busy, transmission of DG PUSCH3 is skipped. The channel access type indicated by DCI may be the channel access type corresponding to index 3 in table 1, i.e. interception of 9 μs or 16 μs specified in the protocol.

For uplink transmission of a configuration in an uplink transmission cluster, for example: CG PUSCH1, CG PUSCH2, or CG PUSCH3 as shown in fig. 4, which were preceded by other uplink transmissions, correspond to DG PUSCH1, DG PUSCH2, and CG PUSCH2, respectively, and the terminal transmits within its own initiated COT (i.e., UE-initiated COT). If the DG PUSCH1 transmission is unsuccessful, the terminal LBT before CG PUSCH1 transmission, with a listening slot length (sensing slot duration) of at least 9us or 16us, immediately adjacent to CG PUSCH1. And if the channel is empty, the CG PUSCH1 is transmitted, and if the channel is busy, the transmission of the CG PUSCH1 is skipped. Similarly, if DG PUSCH2 transmission is unsuccessful, the terminal performs LBT before CG PUSCH2 transmission, where the length of the listening slot is at least 9us or 16us, and the listening slot is immediately adjacent to CG PUSCH2. And if the channel is empty, the CG PUSCH2 is transmitted, and if the channel is busy, the transmission of the CG PUSCH2 is skipped. And similarly, if the CG PUSCH2 transmission is unsuccessful, the terminal listens for a channel of at least 9us or 16us immediately before the CG PUSCH3 transmission, and determines whether to transmit the CG PUSCH3 according to the interception result.
