Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

URLLC related background

The URLLC supports transmission of services such as industrial automation (Factory automation), transport automation (Transport Industry), and intelligent Power (Electrical Power Distribution) in a 5G system. In order to support the transmission of URLLC traffic, the CG is enhanced, that is, at least one CG configuration is introduced, and the specific configuration and use of CG resources (such as a period supporting slot granularity, automatic transmission supporting CG, etc.) are enhanced.

CG enhancement in URLLC

In order to support the high delay requirement of the URLLC service, the URLLC enhances the CG period, and supports a service period of any slot-level granularity.

To support multiple URLLC services and the high latency requirements of URLLC services, URLLC introduced multiple types of CGs (multiplex CG). Hybrid Automatic Repeat reQuest (HARQ) processes configured by different CGs are different, and the different CG processes are guaranteed by configuring a parameter HARQ-ProcID-Offset 2.

Because there is a CG resource and other resource conflict situation, in order to ensure that the grouped mac Data Unit (prioritized medium Access control protocol Data Unit, prioritized mac pdu) in the CG resource is not discarded/transmitted as soon as possible, automatic transmission for CG is introduced. For the CG which is packaged with the mac pdu and cannot be transmitted due to resource collision, the CG resources in the subsequent same HARQ process and the same CG configuration may be used for new transmission. The UE determines to use automatic transmission by configuring a parameter autonomousTx.

NR-U related background

The Third Generation Partnership Project (3 GPP) working group agreed to the establishment of the NR unlicensed operation mode in 12 months in 2018, and the Project aims to enable NR to operate in an unlicensed frequency band, and includes the following operation scenarios:

scene A: in a carrier aggregation scenario, a Primary Cell (PCell) is a licensed spectrum, and secondary cells (scells) working on an unlicensed spectrum are aggregated in a carrier aggregation manner;

scene B: in a dual-connection working scene, a PCell is a Long-Term Evolution (LTE) authorized spectrum, and a Primary and Secondary Cell (PScell) is an NR unauthorized spectrum;

scene C: in an independent working scene, NR is used as an independent cell to work in an unauthorized frequency spectrum;

scene D: in the NR single-cell scenario, an UpLink (UpLink, UL) works in an authorized spectrum, and a DownLink (DownLink, DL) works in an unauthorized spectrum;

scene E: in a double-connection working scene, PCell is an NR authorized spectrum, and PScell is an NR unauthorized spectrum.

Generally, the operating Band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On unlicensed spectrum, the design of NR-U should guarantee fairness with other systems already operating on these unlicensed spectrum, such as WiFi and the like. The principle of fairness is that the impact of NR-U on systems already deployed on unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems over unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. A general energy detection mechanism is an LBT mechanism, and the basic principle of the mechanism is: a base station or a terminal (transmission end) needs to listen for a certain period of time according to a specification before transmitting data on an unlicensed spectrum. If the sensed result indicates that the channel is in an idle state, the transmitting end may transmit data to the receiving end. If the interception result indicates that the channel is in an occupied state, the transmission end needs to back off for a period of time according to the specification and then continue to intercept the channel, and the data can be transmitted to the receiving end only if the channel interception result is in an idle state.

Four channel access mechanisms (categories) are currently defined in NR-U:

category 1: the direct transmission mechanism comprises:

this mechanism is used for the transmission side to transmit quickly after a switching gap (switching gap) within a Channel Occupancy Time (COT); wherein, switching gap refers to the Switching time of received transmission, and the typical value is not more than 16us;

category 2: LBT mechanism without random backoff (back-off)

This mechanism means that the time for which the UE listens to the channel is certain, and is generally short, for example, 25us;

category 3: LBT mechanism (contention window fixed) for random backoff (back-off)

In the LBT process, a transmission side randomly removes a random value in a contention window to determine the time for monitoring a channel;

category 4: LBT mechanism of random backoff (back-off) (contention window is not fixed)

In the LBT procedure, the transmitting side randomly takes a random value in a contention window to decide the time for listening to the channel, and the contention window is variable.

In summary, for a terminal, it is necessary for the base station to transmit data to the terminal within the Maximum Channel Occupation Time (MCOT), and if the base station does not occupy the channel, that is, outside the MCOT, the terminal does not receive the scheduling data from the base station to the terminal.

Uplink LBT failure in NR-U

For uplink transmission initiated by the UE, the following categories are mainly included:

SR (scheduling request): for requesting uplink resources;

physical Random Access Channel (PRACH) transmission: due to RACH trigger, the UE needs to send msg1;

physical Uplink Shared Channel (PUSCH) transmission: the method comprises the steps of CG-based uplink data transmission and Dynamic scheduling (DG) -based uplink data transmission;

physical layer signaling transmission: the method comprises the steps of acknowledgement/negative acknowledgement (ACK/NACK) feedback, channel-state Information (CSI) reporting and the like;

in the unlicensed band, the UE needs to listen to whether the channel is available or not by LBT before transmitting SR, PRACH or PUSCH. If the channel is not available, i.e., LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If detecting the LBT failure, the physical layer needs to notify the MAC layer of the LBT failure information.

CG enhancement in NR-U

For flexible resource selection, the HARQ process of the NR-UCG is not calculated according to a formula, but is selected by the UE itself. For a CG resource, the RRC configures a HARQ process set, and the UE can select one HARQ process in the HARQ process set for the CG transmission. The specifically configured HARQ process interval is determined by a parameter HARQ-ProcID-Offset and a parameter nrofHARQ-Processes.

To support the back-to-back resource configuration, NR-U introduces multiple types of CG (multiplex CG). At least one CG configuration may share HARQ processes.

A CG retransmission timer (CG-retransmission timer) is introduced to support automatic retransmission of resources when CG resources cannot be transmitted due to LBT failure. After the CG retransmission timer expires, if the CG timer (ConfiguredGrantTimer) does not expire, the corresponding HARQ process may be retransmitted.

CG transmission may be interrupted by Downlink Control Information (DCI) and Downlink Feedback Information (DFI) in dynamic scheduling. The specific behavior is shown in the following table one:

Optionally, for one UE or one CG, the network device configures only the CG resource of the first type CG or the CG resource of the second type CG to the terminal; alternatively, the network device configures only the CG parameter of the first-type CG and the CG parameter of the second-type CG to the terminal.

Optionally, for one CG, the network device configures a corresponding HARQ process resource, or HARQ process parameter, to the terminal.

Optionally, the network device configures, to the terminal, a corresponding HARQ process resource for the CG resource.

Optionally, for one HARQ process, the HARQ process is shared by the first type CG and the second type CG. Alternatively, the first type CG and the second type CG share at least part of the HARQ process.

Optionally, the network device configures, to the terminal, an indication indicating whether the HARQ process is shared, or an indication indicating whether the HARQ process is shared by URLLC and NRUCG.

For example, the network device sends first indication information to the terminal, where the first indication information is used to indicate that the HARQ process of the CG resource is determined by using the first HARQ process determining manner and/or the second HARQ process determining manner;

the first HARQ process determining mode is a HARQ process determining mode corresponding to the first type CG, and the second HARQ process determining mode is a HARQ process determining mode corresponding to the second type CG.

Step 340: under the condition that the terminal is configured with the first type configuration authorization CG and the second type CG at the same time, HARQ processes of the first type CG and the second type CG are not shared, or at least one HARQ process is shared between the HARQ processes of the first type CG and the second type CG;

step 360: and the terminal determines the HARQ process of the CG resource according to a first rule.

When determining the HARQ process of the CG resource according to the first rule, the method includes, but is not limited to, at least one of the following ways:

determining the HARQ process of the CG resource by adopting a first HARQ process determination mode;

determining the HARQ process of the CG resource by the second HARQ process determination method.

In one possible design, the terminal determines the HARQ process of the CG resource according to a first HARQ process determination mode, which is a HARQ process determination mode corresponding to the first type CG; or determining the HARQ process of the CG resource according to a second HARQ process determination mode, wherein the second HARQ process determination mode is the HARQ process determination mode corresponding to the second type CG.

For example, for a CG resource configured by a first type CG, an HARQ process of the CG resource is determined according to an HARQ process determination manner of an NR system; or, determining the HARQ process of the CG resource according to the HARQ process determination mode corresponding to the URLLC service transmission; or, determining the HARQ process of the CG resource according to the HARQ process calculation formula.

For example, for the CG resources configured by the second type CG, determining the HARQ process of the CG resources according to the HARQ process determination mode in the unlicensed bandwidth or the NR-U system; or, determining the HARQ process of the CG resource according to the HARQ process determination mode when the unauthorized bandwidth or the NR-U system supports the uplink service; or, determining the HARQ process of the CG resource according to the mode selected by the UE.

In one possible design, according to predefined or default settings or first indication information or first CG configuration information, determining HARQ processes of CG resources in a first HARQ process determination manner;

or the like, or, alternatively,

and determining the HARQ process of the CG resources according to a second HARQ process determination mode according to predefined or default setting or first indication information or first CG configuration information.

Optionally, as shown in fig. 4, the indication manner of the first indication information includes, but is not limited to, at least one of the following:

1. the network equipment sends a system broadcast, the terminal receives the system broadcast, and the system broadcast carries first indication information;

the System broadcast includes a System Information Block (SIB). The network equipment sends a certain SIB, and the SIB carries first indication information.

2. The network equipment receives a special signaling, and the special signaling carries first indication information;

the proprietary signaling is UE-specific signaling such as RRC messages, MAC CEs, or DCI. The network equipment sends a special signaling, and the special signaling carries the first indication information.

Optionally, the first indication information is configured for each terminal or a single terminal; or, the first indication information is configured for each CG or a single CG; or, the first indication information is configured for each CG group or a single CG group; or, the first indication information is configured for each HARQ process or a single CG.

For example, for CG index 1, the network device indicates, to the UE, CG resources for CG index 1, and preferentially selects the first HARQ process determining manner to determine the corresponding HARQ process when the CG resources are transmitted.

For another example, for CG index 3, the network device indicates the resource for CG index 3 to the UE, and preferentially selects the second HARQ process determination method to determine the corresponding HARQ process when CG resource transmission is performed.

For another example, the UE receives the first CG configuration information of the network, configures the corresponding CG resource according to the first CG configuration information, and transmits the CG resource using the corresponding CG resource. For one available CG resource:

if the network equipment only configures one type of CG for the UE, for example, the first type of CG is configured, determining the HARQ process of the CG resource according to a first HARQ determining mode; for another example, a second type CG is configured, and the HARQ process is determined according to a second HARQ determining method.

For another example, the UE receives the first CG configuration information of the network, configures the corresponding CG resource according to the first CG configuration information, and transmits the CG resource using the corresponding CG resource. And determining the HARQ process according to the second HARQ determining mode for one available CG resource, whether the CG resource is the first type CG or the second type CG, or whether the parameter of the first type CG or the parameter of the second type CG is configured.

For another example, the UE receives the first CG configuration information of the network, configures the corresponding CG resource according to the first CG configuration information, and transmits the CG resource using the corresponding CG resource. For an available CG resource, whether the CG resource is the first type CG or the second type CG, or whether the parameter of the first type CG or the parameter of the second type CG is configured, determining the HARQ process according to the first HARQ determining mode.

For another example, the UE receives first CG configuration information of the network, and determines the HARQ determination method according to whether the NR or NR-U system is accessed. For example, if the NR system is accessed, the HARQ process is determined according to the first HARQ determining method. For example, if the access is an NR-U system, the HARQ process is determined according to the second HARQ determination mode.

If the (all) HARQ processes are not shared by the CG resource, or if the (all) HARQ processes are not shared by the first type CG and the second type CG, determining the HARQ processes according to the following rule:

and if the first condition is met, using a first HARQ process determination mode, namely the HARQ process calculated according to the HARQ calculation formula. The first condition is at least one of:

3. At least one of the following configuration parameters is not configured for the CG resources: a CG retransmission timer (CG-retransmission timer), a first HARQ process Offset HARQ-ProcID-Offset, a COT related parameter, a number of CGs per slot (nroflcg-slot), a number of PUSCHs per slot (nroflsch), at least one of the number of PUSCHs per slot (nroflusch). These parameters are used to configure CG transmission resources.

4. At least a CG resource or a MAC entity corresponding to the CG resource is configured with a logical channel-based priority determination (lch-based priority). The lch-based priority is used to select the resources for preferential transmission.

And if the second condition is met, a second HARQ process determining mode is used, namely the UE autonomously selects the used HARQ process in the configured HARQ resource pool. The second condition is at least one of:

the CG resource is a second type CG;

and 2, the CG resource configuration mode is a second type CG configuration mode, namely, the configuration mode comprises specific configuration parameters of the second type CG configuration, such as at least one of CG retransmission timer CG-retransmission timer, harq-ProcID-Offset, COT related parameters, nroflcg-slot and nroflPUSCH.

4. not configuring at least a second HARQ process Offset (HARQ-ProcID-Offset 2) for CG resources;

In one possible design, for one or a group of CG resources, the terminal preferentially determines the first HARQ process using the first HARQ process determination method; and if the first HARQ process meets the first judgment condition, determining a second HARQ process by using a second HARQ process determination mode to serve as the HARQ process of the CG resource.

In one possible design, for one or a group of CG resources, the terminal preferentially determines the first HARQ process using the first HARQ process determination method; and if the first HARQ process meets the second judgment condition, taking the first HARQ process as the HARQ process of the CG resource.

In one possible design, for one or a group of CG resources, the terminal determines the HARQ process with priority using the second HARQ process determination method; if the preferentially selected HARQ process meets the third judgment condition, determining the first HARQ process by using a first HARQ process determination mode; and determining the first HARQ process as the HARQ process of the CG resource.

Wherein the third decision condition includes any one of the following conditions:

the number of HARQ processes to be preferentially selected is plural;

the preferred HARQ process is multiple and includes a first HARQ process;

the terminal determines the HARQ process which is selected preferentially by using a second HARQ process determination mode; if the HARQ process selected preferentially is multiple (multiple retransmissions are to be transmitted or multiple new transmissions are to be transmitted), determining a first HARQ process by using a first HARQ process determination mode; and if the preferentially selected HARQ process comprises a first HARQ process, determining the first HARQ process as the HARQ process of the CG resource.

There is a low priority mac pdu in the first HARQ process;

there is no data that fails to be transmitted due to LBT failure;

there is no data shared by the corresponding CG process that fails to transmit due to LBT failure.

In one possible design, for one or a group of CG resources, the terminal determines the HARQ process of the priority selection using a second HARQ process determination manner; if a plurality of preferentially selected HARQ processes exist, determining a first HARQ process by using a first HARQ process determination mode; and if the preferentially selected HARQ process does not comprise the first HARQ process, selecting one HARQ process by adopting an autonomous selection mode to determine the HARQ process as the CG resource.

In one possible design, for one or a group of CG resources, the terminal determines the HARQ process of the priority selection using a second HARQ process determination manner; and if the preferentially selected HARQ process meets the fourth judgment condition, determining the preferentially selected HARQ process as the HARQ process of the CG resource.

Wherein the fourth decision condition includes any one of the following conditions:

the presence of data that failed LBT resulting in failure to transmit;

there is data corresponding to the CG process that failed to transmit due to LBT failure;

there is no low priority mac pdu.

In a possible design, when the terminal receives the downlink feedback information DFI to stop the CG retransmission timer or the CG retransmission timer is overtime, the terminal preferentially selects the second HARQ process determined by the second HARQ process determining method to be the HARQ process of the CG resource. The second HARQ process is also referred to as a preferred HARQ process.

Further, if there are multiple HARQ processes (multiple retransmissions waiting for transmission, or multiple new transmissions waiting for transmission) meeting the priority selection, the UE preferentially uses the HARQ processes calculated according to the HARQ calculation formula; or if a plurality of HARQ processes meeting the priority selection include the HARQ processes calculated according to the HARQ calculation formula, the UE preferentially uses the HARQ processes calculated according to the HARQ calculation formula; or if a plurality of HARQ processes meeting the preference selection are available and do not contain the HARQ processes calculated according to the HARQ calculation formula, the UE autonomously selects one HARQ process.

In one possible design, when the CG resource is a CG resource corresponding to a second type CG, the terminal determines an HARQ process of the CG resource by using a second HARQ process determining manner; and when the CG resources are the CG resources corresponding to the first type CG, the terminal determines the HARQ process of the CG resources by adopting a first HARQ process determination mode.

In one possible design, when the CG resources are configured by CG resource configuration parameters corresponding to a second type of CG, the terminal determines the HARQ process of the CG resources by using a second HARQ process determination manner; and when the CG resources are configured according to the CG resource configuration parameters corresponding to the first type of CG, the terminal determines the HARQ process of the CG resources by adopting a first HARQ process determination mode.

In one possible design, the HARQ process of the CG resource is determined using a second HARQ process determination. For example, when the first type CG and the second type CG do not share the HARQ process, the second HARQ process determining method is always used to determine the HARQ process of the CG resource.

In one possible design, the HARQ process of the CG resource is determined using a second HARQ process determination. For example, in the NR-U system, no matter which type of CG is used, or the CG configured according to the configuration parameters of which type of CG is used, the HARQ process of the CG resource is always determined by using the second HARQ process determining method.

It should be noted that the first rule is configured for each terminal or a single terminal; or, the above-mentioned first rule is configured for each CG or a single CG; or, the first rule is configured for each CG group or a single CG group; alternatively, the first rule is configured for each HARQ process or a single HARQ process.

The following are some illustrative examples:

if an available CG resource of CG index 1 is shared by HARQ process 1 configured by the network device, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula and uses the HARQ process for transmission. For any CG resource of CG index 1, or HARQ process 1 (shared process) of CG index 1, exemplarily, if the CG timer is not running, transmitting according to a new transmission; if the CGtimer is running, but the CG retransmission timer configuration is not running, according to retransmission transmission.

If one available CG resource of CG index 1 is shared by the HARQ process 1 configured for the network equipment, and for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. And if the determined HARQ processes are the non-shared HARQ processes 2 and 3, transmitting according to the HARQ process determined by the HARQ process calculation formula. If the determined HARQ process is the shared HARQ process 1, finally determining which one of the used HARQ processes is 1/4/5 according to an NRU mode, or if the HARQ process 1 is occupied and the MAC PDU carried in the occupied process is not low priority, determining the HARQ process by the UE according to an NRUHARQ process calculation mode.

If an available CG resource of CG index 1 is shared by HARQ process 1 configured by the network device, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process determination method corresponding to the NRU.

If an available CG resource of CG index 1 is configured in an NRU system or frequency band, for any available CG resource, the UE preferentially determines an HARQ process according to an HARQ process determination mode corresponding to the NRU.

If one available CG resource of the CG index 3 is shared by the HARQ process 1 configured by the network device, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process determination manner corresponding to the NR system.

If an available CG resource of CG index 3 is shared by HARQ process 1 configured by the network device, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. And the HARQ process transmission determined by the HARQ process formula is used no matter whether the determined HARQ process is the HARQ process supported by the CG resource.

If one available CG resource of CG index 3 is shared by HARQ process 1 configured by the network device, for any available CG resource, the UE preferentially determines the HARQ process according to the HARQ process calculation formula. And if the HARQ process determined according to the HARQ process formula is not the HARQ process supported by the CG, the UE determines the HARQ process according to the HARQ process determination mode corresponding to the NRU.

In summary, the method provided in this embodiment provides a method for determining how to determine the HARQ process for the CG resource under the condition of configuring the first-type CG and the second-type CG at the same time, so as to ensure consistent understanding of the network device and the terminal, and to make clear the behavior of the terminal.

Fig. 5 shows a flowchart of a HARQ determining method according to an embodiment of the present application. Fig. 5 is illustrated as the method is applied to the communication system shown in fig. 1. The method comprises the following steps:

For example, CG index 1 and CG index 2 correspond to a first type CG, and the corresponding HARQ processes are process 1, process 2, and process 5.CG index 5 and CG index 4 correspond to the second type CG, and the corresponding HARQ processes are process 1, process 4 and process 5. The first type CG and the second type CG share the HARQ process 1.

The network equipment sends third CG configuration information to the terminal, wherein the third CG configuration information is used for simultaneously configuring the first type CG and the second type CG or simultaneously configuring the first type CG configuration parameter and the second type CG configuration parameter. Optionally, the third CG configuration information is an RRC message for CG configuration, also called RRCCG configuration information.

Optionally, the network device configures, to the terminal, an indication indicating whether different types of CGs are configured at the same time, or an indication indicating whether parameters of different types of CG configurations may occur at the same time.

Optionally, the network device further configures a second rule to the terminal, where the second rule is used to determine a transmission manner of the CG resource. The second rule may be carried in the third CG configuration information, or in the second indication information, or in other information, such as broadcast, mac ce, DCI, other dedicated RRC message, and the like. For example, the network device sends second indication information to the terminal, where the second indication information is used to indicate that the transmission method of the first-type CG and/or the transmission method of the second-type CG are/is determined as the transmission method of the CG resource.

Step 540: under the condition that the terminal is configured with the first type configuration authorization CG and the second type CG at the same time, HARQ processes of the first type CG and the second type CG are not shared, or at least one HARQ process is shared between the HARQ processes of the first type CG and the second type CG;

determining the transmission mode of the CG resource by adopting the transmission mode of the first type CG;

the transmission method of the CG resource is determined by using the transmission method of the second type CG.

In one possible design, the terminal determines a transmission mode of the CG resource according to a transmission mode of a first type CG, where the transmission mode of the first type CG is a transmission mode corresponding to the first type CG; or, determining the transmission mode of the CG resource according to the transmission mode of the second-type CG, where the transmission mode of the second-type CG is a transmission mode corresponding to the second-type CG.

In one possible design, the transmission mode of the CG resources is determined according to the transmission mode of the first type CG according to predefined or default setting or second indication information or third CG configuration information;

or the like, or a combination thereof,

3. Fourth CG configuration information is received. Optionally, the fourth CG configuration information carries second indication information.

Optionally, the fourth CG configuration information is an RRC message.

Optionally, the CG resource transmission method is determined according to the CG resource configuration parameter or the configuration method in the first CG configuration information.

Optionally, when there is a HARQ process shared by the first type CG and the second type CG, the network device sends second indication information to the UE, indicating a transmission manner of the CG resource.

When the second indication information indicates that the transmission mode of the CG resource is the transmission mode of the first type CG, adopting a CG transmission mode corresponding to high reliability and low time delay, wherein the CG transmission mode comprises at least one of the following modes: the method comprises the steps of carrying no UpLink Control Information (UCI) Information, adopting a high-reliability low-delay (such as URLLC) format for transmission, adopting CG resources configured in a CG resource configuration mode corresponding to the high-reliability low-delay (such as URLLC) for transmission, and carrying out transmission according to specific configuration parameters of the first type of CG.

For example, for CG index 1, the network device indicates the CG resource for CG index 1 to the UE, and when the CG resource is transmitted, a CG transmission method corresponding to NRU is used, and when the CG is transmitted, NRU format is used for transmitting all CGs of CG index 1, and UCI information is carried during transmission.

For example, for CG index 1, the network device indicates, to the UE, CG resources corresponding to CG index 1 and HARQ process 1, and when the CG resources are transmitted, a CG transmission mode corresponding to NRU is adopted, and then the HARQ process 1 is selected from the CG index 1 to transmit CG, and when the CG is transmitted, the CG is transmitted in NRU format, and carries UCI information. And other rest CG resources adopt a CG transmission mode corresponding to the URLLC.

For example, for CG index 3, the network device indicates, to the UE, CG resources for CG index 3, and when the CG resources are transmitted, a CG transmission method corresponding to NRU is adopted, and when the CG resources are transmitted, all CGs for CG index 3 are transmitted in NRU format, and when the CG resources are transmitted, UCI information is carried.

And when the network equipment does not send the second indication information to the terminal, the terminal determines the transmission mode of the CG resources according to the transmission mode of the first type CG or the second type CG according to a predefined mode. The predefined manner includes, but is not limited to, at least one of the following:

For example, if only one CG mode is configured for the UE, such as the second type CG or the first type CG, the transmission is performed according to the second type CG transmission mode, or the transmission is performed according to the first type CG transmission mode; or, if only one CG mode is configured for the UE, for example, the second type CG or the first type CG is transmitted according to the second type CG transmission mode.

2. If multiple CG configuration modes exist for the UE at the same time, for example, the second type CG and the first type CG are transmitted according to a second type CG transmission mode. Or if the CG resources are configured on the NRU system or the frequency point, adopting a transmission mode of the second type CG.

3. If multiple CG configuration modes exist for the UE at the same time, such as a second type CG and a first type CG, the second type CG is transmitted according to a second type CG transmission mode, and the first type CG is transmitted according to a first type CG transmission mode. Optionally, the CG resource transmission manner is determined according to the CG resource configuration parameter or configuration manner in the CG configuration information. Optionally, the method is applicable to a scenario in which all HARQ processes are not shared by the first type CG and the second type CG.

In one possible design, a second type of CG transmission scheme is employed. For example, when the first-type CG and the second-type CG do not share the HARQ process, the transmission scheme of the second-type CG is always used.

In one possible design, if CG resources are allocated in NR-U systems or frequency bins, a second type of CG transmission scheme is used.

(scenario: for a UE, HARQ processes of partial CG resources are not shared, HARQ processes of partial CG resources are shared.
