Description

Data transmission method and terminal equipment

Technical Field

The present application relates to the field of communications, and in particular, to a method and a terminal device for transmitting data.

Background

To better serve periodic traffic, the concept of pre-configured resources is introduced, including, for example, Semi-Persistent Scheduling (SPS) (for downlink) and Configured Grant (CG) (for uplink). For the UE, the number of maximum Hybrid Automatic Repeat reQuest (HARQ) processes is 16, for each CG configuration, the network configures a limited number of HARQ process numbers for the CG, and the HARQ process number of the CG resource at time t0 is the same as the HARQ process number of the CG resource at time t1, where time t0 and time t1 are corresponding times of any two CG resources in the periodic CG resources configured for the terminal device by the network device.

In addition, when a Media Access Control (MAC) Protocol Data Unit (PDU) 1 is packaged at time t0, an MAC PDU1 is stored in HARQ process a; after time t1, MAC PDU1 will be emptied (flush) due to the same HARQ process, even if MAC PDU1 has not been transmitted correctly at this time. Therefore, a mechanism of configuring a granted Timer (CG Timer) is introduced for each HARQ process.

In addition, in order to prevent CG resources from overwriting Transport Blocks (TBs) or MAC PDUs generated due to previous dynamic scheduling, a timer for CG automatic retransmission, called CG retransmission timer (CG Retx timer), is also introduced.

However, the prior art only defines the CG timer, and does not consider the problem of how to handle when configuring the CG timer and the CG Retx timer at the same time.

Fig. 1 exemplarily shows one network device and two terminal devices, and optionally, the communication system 100 may include a plurality of network devices and may include other numbers of terminal devices within the coverage of each network device, which is not limited in this embodiment of the present application.

Optionally, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The NR operating in the Unlicensed frequency band (NR in Unlicensed Spectrum, NR-U) includes the following operating scenarios: a carrier aggregation scenario: a Primary cell (PCell) is an authorized spectrum, and Secondary cells (scells) operating on an unauthorized spectrum are aggregated in a carrier aggregation manner; double-connection working scene: the PCell is an LTE authorized spectrum, and a Primary Secondary Cell (PScell) is an NR unauthorized spectrum; independent working scene: the NR operates as an independent cell in unlicensed spectrum.

Generally, the operating Band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum, for example, 5925-7125 MHz in the United States (US) or 5925-6425 MHz in Europe (European). On unlicensed spectrum, the design of NR-U should guarantee fairness with other systems already operating on these unlicensed spectrum, such as wireless (WiFi) and the like. The principle of fairness is that the impact of NR-U on systems already deployed on unlicensed spectrum (e.g., 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 a Listen Before Talk (Listen Before Talk, LBT) mechanism. The basic principle of the mechanism is as follows: 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 continues to intercept the channel until the channel interception result is in an idle state, and data can not be transmitted to the receiving end.

To better serve periodic traffic, the concept of pre-configured resources is introduced, including, for example, SPS (for downlink) and CG (for uplink). Since the maximum number of HARQ processes for the UE is 16, for each CG configuration, the network configures a limited number of HARQ process numbers for the UE, and the HARQ process number of the CG resource at time t0 is the same as the HARQ process number of the CG resource at time t1, where time t0 and time t1 are corresponding times of any two CG resources in the periodic CG resources configured for the terminal device by the network device.

In addition, when the MAC PDU1 is packaged at time t0, the MAC PDU1 is stored in the HARQ process A; after time t1, MAC PDU1 will be emptied (flush) due to the same HARQ process, even if MAC PDU1 has not been transmitted correctly at this time. Therefore, a CG timer mechanism is introduced for each HARQ process. Before the CG Timer times out, the MAC PDU stored in the HARQ process cannot be flushed. The timer is started or restarted when the transmission is scheduled, or when the transmission is performed, by the C-RNTI.

In addition, to prevent CG resources from covering TBs or MAC PDUs generated due to previous dynamic scheduling, in a 105bis conference, the following conclusion is reached on CG transmission issues: a timer for automatic retransmission of CG, called CG retransmission timer (CG Retx timer), is introduced and the existing CG timer is adopted.

However, the prior art only defines the CG timer, and does not consider the problem of how to handle when configuring the CG timer and the CG Retx timer at the same time. In addition, the current definition of CG Retx timer may cause the UE to continuously perform unnecessary automatic retransmission, resulting in resource waste.

Therefore, the present application provides a method for transmitting data, which can solve the above problem.

Fig. 2 is a schematic flow chart of a method 200 for transmitting data according to an embodiment of the present disclosure. The method 200 may be performed by a terminal device, which may be, for example, the terminal device shown in fig. 1. As shown in fig. 2, the method 200 includes: s210, a terminal device receives configuration authorized resource indication information sent by a network device, where the configuration authorized resource indication information is used to indicate a configuration authorized resource set configured for the terminal device by the network device, and the configuration authorized resource set includes a target HARQ process.

Specifically, the network device configures CG resources for the connected terminal device, that is, the network device sends CG resource indication information to the terminal device, where the CG resource indication information is used to indicate a CG resource set, the CG resource set includes at least one group of CG resources, and each group of CG resources in the at least one group of CG resources is a periodic CG resource, that is, the interval periods of the CG resources in the same group are equal.

It should be understood that the CG resource indication information sent by the network device to the terminal device may include a cycle of the CG resource and additionally include a target HARQ process corresponding to the CG resource.

As shown in fig. 2, the method 200 further includes: s220, if the terminal device receives a first dynamic resource indication message sent by the network device, the terminal device starts a configuration authorization timer, where the first dynamic resource indication message is used to indicate a first dynamic resource allocated by the network device for the target HARQ of the terminal device, and the configuration authorization timer corresponds to the dynamic resource.

It should be understood that the configuration authorization timer (CG timer) in the embodiment of the present application may also be referred to by other names, where the CG timer represents a timer corresponding to a dynamic resource, that is, the CG timer is used for a terminal device to time a process of using the dynamic resource.

As shown in fig. 2, the method 200 further includes: s230, if the terminal device transmits data by using the first configuration authorized resource in the configuration authorized resource set, the terminal device starts a configuration authorized retransmission timer, where the configuration authorized retransmission timer and the configuration authorized retransmission timer do not operate simultaneously, and the configuration authorized retransmission timer corresponds to the configuration authorized resource.

It should be understood that the configuration authorization retransmission timer (CG Retx timer) in the embodiment of the present application may also be referred to by other names, where the CG Retx timer represents a timer corresponding to a CG resource, that is, the CG Retx timer is used for a terminal device to time a process using the CG resource.

In this embodiment, the CG resource indication information sent by the network device to the terminal device may further include a duration of the CG timer and/or a duration of the CG Retx timer. Wherein, the time length of the CG timer can be integer times of the CG resource period; and/or the length of the CG Retx timer can be integer times of the CG resource period. In addition, the CG timer and the CG Retx timer may be the same or different.

In the embodiment of the application, the CG timer and the CG Retx timer are not operated at the same time, that is, at most, only one of the two timers can be operated at any time. The opening, operation and timeout of the CG timer and CG Retx timer will be described in detail below with reference to FIG. 3.

Fig. 3 shows a schematic diagram of a time axis of a method of transmitting data according to an embodiment of the application. As shown in fig. 3, it is assumed that at an arbitrary time in the time domain, that is, at time t0, the terminal device receives CG resource indication information sent by the network device, where the CG resource indication information is used to indicate a CG resource set, and it is assumed that a plurality of CG resources with a certain period are included in the CG resource set.

It should be appreciated that the configuration grant means generally includes a first type of configuration grant (type-1 configured grant) and a second type of configuration grant (type-2 configured grant).

First type configuration authorization: the network device configures transmission resources for the terminal device through Radio Resource Control (RRC) signaling. For example, the RRC signaling configuration may include: time domain resources, frequency domain resources, Demodulation Reference signals (DMRSs), power control, Modulation and Coding Scheme (MCS), Waveform (Waveform), Redundancy Version (RV), number of repetitions, frequency hopping, number of HARQ processes, and other all transmission resources and transmission parameters. After receiving the higher layer parameter, the terminal device may immediately use the configured transmission parameter to perform data transmission on the configured time-frequency resource, for example, perform Physical Uplink Shared Channel (PUSCH) transmission.

The second type of configuration authorization: firstly, configuring part of transmission resources and transmission parameters, such as transmission resources and transmission parameters including the period of time-frequency resources, open-loop power control, waveform, redundancy version, retransmission times, frequency hopping, HARQ process number and the like, by using high-level parameters (such as configuredGrantConfig); and then activating data transmission of a second type of configuration grant, such as PUSCH transmission, by Downlink Control Information (DCI), and simultaneously configuring other transmission resources and transmission parameters including time domain resources, frequency domain resources, DMRS, MCS, and the like. When receiving the higher-layer parameter ConfiguredGrantConfig, the terminal device cannot immediately use the resource and parameter configured by the higher-layer parameter to perform PUSCH transmission, and must wait for receiving corresponding DCI activation and configuring other resources and transmission parameters to perform PUSCH transmission. In addition, the network device may deactivate the configuration transmission through the DCI, and when the terminal device receives the deactivated DCI, the terminal device may no longer use the transmission resource for transmission.

In this embodiment of the application, at time t0, the CG resource indication information received by the terminal device may be a first-type configuration authorization or a second-type configuration authorization. When the terminal equipment receives the CG resource indication information, the relevant configuration is stored. If the CG is the CG of type2 (i.e. RRC configuration is required first, and then DCI indicates activation), the terminal device activates or starts to use the CG resource in the CG resource set according to DCI indication of the network device.

It should be understood that, the terminal device receives the CG resource indication information at time t0, and the starting time of the first CG resource in the time domain, among the multiple CG resources indicated by the CG resource indication information in the periodicity, may be any time after time t0 or time t0, and the embodiment of the present application is not limited thereto.

It should be understood that the CG resource indication information received by the terminal device is also used to indicate the target HARQ process. Specifically, the CG resource indication information may indicate one or more HARQ processes, and for convenience of description, any one of the HARQ processes is taken as an example here, that is, a target HARQ process is taken as an example.

In the embodiment of the present application, two types of resources, namely, dynamic resources and CG resources, are mainly involved, and the following description will be made separately for the two types of resources and the use of corresponding timers.

First, for dynamic resources. As shown in fig. 3, assuming that the terminal device receives the first dynamic resource indication information sent by the network device at any time t1 after time t0, the terminal device starts a CG timer. Wherein, the first dynamic resource indication information is used to indicate the first dynamic resource allocated by the network device for the target HARQ of the terminal device; in addition, the first dynamic resource indication information may also be used to indicate that the first dynamic resource is used for scheduling a new transmission or a retransmission. For example, the first dynamic resource indication information may be a DCI indication.

Optionally, the specific time when the CG timer is started by the terminal device may be any one of the following: when the terminal device receives the first dynamic resource indication information, namely at time t1, the terminal device starts the CG timer; the terminal equipment starts a Physical Downlink Control Channel (PDCCH) CG timer for uplink transmission resources received on an occasion (Scheduling) of the PDCCH, wherein the PDCCH includes the first dynamic resource indication information, and the PDCCH is scrambled by a Cell-Radio Network Temporary Identifier (C-RNTI) or a Configured scheduled Radio Network Temporary Identifier (CS-RNTI); when the terminal device executes transmission corresponding to the uplink transmission resource indicated by the first dynamic resource indication information, that is, at the starting time of the first dynamic resource indicated by the black square after the time t1 in fig. 3, the terminal device starts the CG timer. In addition, the CG timer may be activated by the terminal device when receiving and transmitting the DCI.

Alternatively, assuming here that the CG timer has started and is running, for example, the CG timer started at time t1, after time t1, there may be at least one of the following.

In case that the CG timer is running and has not timed out, for example, at time t2 in fig. 3, assuming that time t2 corresponds to a time of using a second CG resource in a CG resource set configured by the network device, or t2 is a starting time of the second CG resource, since the CG timer is still running at this time and the MAC does not want the target HARQ process to deliver an authorized resource, the terminal device determines not to use the second CG resource in the CG resource set, that is, the second CG resource is skip or is not used. Wherein, the second CG resource may refer to: any one of the start times is located at a CG resource subsequent to the start time of the first dynamic resource while the CG timer is running.

In case that the CG timer is running and not timed out, for example, at time t3 in fig. 3, it is assumed that at time t3, the terminal device receives second dynamic resource indication information sent by the network device, where the second dynamic resource indication information is used to indicate a second dynamic resource allocated by the network device for the target HARQ of the terminal device, for example, a PDCCP scrambled by a C-RNTI or a CS-RNTI includes the second dynamic resource indication information; in addition, the second dynamic resource indication information may also be used to indicate a new transmission or a retransmission for the target HARQ process. At this time, the terminal device stops the timing of the CG timer on the first dynamic resource no matter whether a new transmission or a retransmission is scheduled; further, the terminal device may restart the CG timer, that is, the time t3 is consistent with the time t1, and restart the CG timer to time a process in which the terminal device uses the second dynamic resource, where the specific process is consistent with the first dynamic resource, and is not described herein again for brevity.

In case three, as shown in fig. 3, assuming that the CG timer times out at time t4, the terminal device determines that the data transmission transmitted through the first dynamic resource is successful, and/or the terminal device determines that the data transmission of the target HARQ is successful. Namely, the terminal device completes the data transmission of the first dynamic resource, and the CG timer completes the timing of the first dynamic resource.

The above description is directed to the dynamic resource and the starting and using process of the CG timer corresponding to the dynamic resource, and the following description is directed to the CG resource.

As shown in fig. 3, it is assumed that at any time t5 after time t0, a first CG resource in a CG resource set configured by a network device is available, that is, time t5 is the available time of the first CG resource, or time t5 is the starting time of the first CG resource; and assuming that the CG timer is not running at this time, the terminal device determines that data can be transmitted using the first CG resource, and starts the CG Retx timer.

It should be understood that the time t5 may be any time after the time t0, and it is assumed that the CG timer is not running at the time t 5; correspondingly, the first CG resource may be any one CG resource in the set of CG resources indicated by the CG resource indication information.

Optionally, the specific time when the CG Retx timer is started by the terminal device may be: the CG Retx timer is started at the starting time of the first CG resource, namely, the CG Retx timer is started by the terminal equipment at the resource transmission time.

It should be understood that the terminal device may use the first CG resource for data new transmission or retransmission. To avoid the problem of performing automatic retransmission an unlimited number of times, a retransmission Counter (COUTNER) or a preset timer is introduced to limit the number of automatic retransmissions or the time of the CG resource.

Specifically, for the case of using COUTNER, the maximum value of the COUTNER record is set here to a preset value representing the maximum number of times of automatic retransmission by the terminal device. Optionally, the preset value of the COUTNER and/or whether to use the COUTNER may be configured for the network device, or may also be predefined, or may also be determined by the terminal device itself, which is not limited in this embodiment of the present application. For example, the CG resource indication information sent by the network device may include the preset value and/or information indicating whether to use the COUTNER; the preset value may be set for the target HARQ or may also be set for the terminal device. For example, if the network device configures COUNTER with a preset value of 3, it implicitly represents that COUTNER is used and/or the preset value is 3. As another example, the explicitly configured information of whether to use COUNTER of the network device is True, which represents that COUNTER is used, otherwise, COUNTER counting is not used.

Similarly, for the case of using a preset timer, the duration of the preset timer indicates that the number of automatic retransmissions is limited. Optionally, the duration of the preset timer and/or whether to use the preset timer may be configured for the network device; alternatively, it may be predefined; alternatively, the determination may be made by the terminal device, and the embodiment of the present application is not limited to this. For example, the CG resource indication information transmitted by the network device includes: the duration of the preset timer and/or information for indicating whether to use the preset timer; the duration of the preset timer may be a multiple of the CG timer, or may also be a multiple of the CG Retx timer. For another example, the information configured by the network device whether to use the preset time is True, which represents that the preset time is used, otherwise, the preset timer is not used.

In the embodiment of the application, the terminal device determines to use the first CG resource for data transmission at time t5, and starts a CG Retx timer, at which time, the COUTNER may not be started or may start counting; similarly, the preset timer may not have started or may have started counting. In either case, it is assumed here that at time t5, the COUTNER has not reached the preset value, and the preset timer has not timed out.

Optionally, first, for a case that the COUTNER may not be started yet, or the counting has been stopped, in a case that the terminal device determines to transmit data using the first CG resource, the CG Retx timer is started, and the COUTNER is also started to record the transmission data of the first CG resource this time.

For example, the COUTNER may be initiated when one of the following conditions is met: after the terminal equipment adopts the dynamic resources to transmit data, the COUTNER is started when the CG resources corresponding to the target HARQ process are adopted to transmit newly transmitted data; when the terminal equipment adopts CG resources to transmit data for the first time, starting the COUTNER; when the terminal equipment has no data in the target HARQ process, the COUTNER is started when CG resources are adopted or adopted for the first time to transmit data; and when the terminal equipment adopts the CG resource corresponding to the target HARQ process to transmit newly transmitted data, starting the COUTNER.

Wherein, the COUTNER start in the embodiment of the present application may indicate that the value of COUTNER is increased from 0 to 1, that is, counted from 1; alternatively, the COUTNER start may also indicate that the value of COUTNER is set to 0 and then 1 is added after one transmission, that is, the COUTNER counts from 0, and the embodiment of the present application is not limited thereto. If the COUTNER starts counting from 1 after being started, the preset value of the COUTNER represents the total number of first transmission and retransmission of data, for example, if the first transmission and the retransmission need to be limited to be performed at most, the corresponding preset value of the COUTNER is set to 3; however, if the COUTNER starts counting from 0 after starting, the preset value of the COUTNER indicates the number of retransmissions of the data, for example, the first transmission and the second retransmission are also limited to be performed at most, and the corresponding preset value of the COUTNER is set to 2.

Similarly, in the case that the preset timer has not been started, or the timing has been stopped, in the case that the terminal device determines to transmit data using the first CG resource, the CG Retx timer is started, and the preset timer is also started.

For example, the preset timer may be started when one of the following conditions is satisfied: after the terminal equipment adopts dynamic resources to transmit data, when the CG resources corresponding to the target HARQ process are adopted to transmit newly transmitted data, a preset timer is started; when the terminal equipment adopts CG resources to transmit data for the first time, starting a preset timer; when the terminal equipment does not have data in the target HARQ process, a preset timer is started when CG resources are adopted or adopted for the first time to transmit the data; and the terminal equipment starts a preset timer when the CG resource corresponding to the target HARQ process is adopted to transmit newly transmitted data.

On the contrary, if the terminal device determines that the COUTNER has started counting when the terminal device transmits data using the first CG resource, but the COUTNER has not reached the preset value, e.g., the COUTNER is smaller than the preset value, the terminal device may start the CG Retx timer, and in addition, may add 1 to the COUTNER record value.

Similarly, if the terminal device determines that the data is transmitted by using the first CG resource, the preset timer has started to time, that is, the preset timer is running and has not timed out, the terminal device may start the CG Retx timer (specifically, if the data transmitted by the first CG resource is not newly transmitted data, or the CG Retx timer is timed out, etc.), and in addition, the terminal device keeps the preset timer to continue to time.

Alternatively, it is assumed here that the CG Retx timer for this first CG resource has been started and is running while COUTNER is also running, or that the preset timer is also running, i.e. after time t5, there may be at least one of the following.

In case one, at a time t6 after the time t5, when the CG Retx timer is running and is not overtime, if the terminal device receives the third dynamic resource indication information sent by the network device, the terminal device stops the CG Retx timer and resets the COUTNER or the preset timer. The third dynamic resource indication information is used to indicate the third dynamic resource allocated by the network device for the target HARQ of the terminal device, and/or the third dynamic resource indication information is used to indicate whether to perform new transmission or retransmission on the target HARQ process.

That is, when the terminal device receives the dynamic resource allocated by the network device, the terminal device will stop the CG Retx timer and also stop the COUTNER or the preset timer, no matter whether the dynamic resource is used for new transmission or retransmission of the target HARQ process.

Optionally, the terminal device receives the third dynamic resource at the time t6, and the use of the third dynamic resource and the corresponding CG timer may be consistent with the use of the first dynamic resource at the time t1, which is not described herein again for brevity.

For the sake of distinction, in other cases than the first case, it is assumed that the terminal device has not received the scheduling of the dynamic resources of the target HARQ by the network device.

In case two, for the time t7 after the time t5, assuming that the time t7 corresponds to a time of use of a second CG resource in the CG resource set configured by the network device, or that t7 is a starting time of the second CG resource, and assuming that the CG Retx timer is running and has not timed out at this time, and likewise, COUTNER is less than or equal to a preset value, and the preset timer has not timed out, the terminal device may determine not to use the second CG resource in the CG resource set, that is, the second CG resource is skip, or is not used. Wherein, the second CG resource may refer to: any one of the start times is located at a CG resource subsequent to the start time of the first CG source during the period that the CG Retx timer and/or preset timer is running.

In case three, for the case that the CG Retx timer is running and not timed out at the time t8 after the time t5, if the terminal device receives Downlink Feedback Information (DCI) sent by the network device and the DFI is Acknowledgement (ACK), the terminal device may suspend the CG Retx timer, for example, the terminal device may execute the first procedure or the second procedure.

Specifically, the time t8 of case three may be set to a time at which any one of the following conditions is satisfied: the method comprises the following steps that a first condition is that the CG Retx timer is running and not overtime, COUTNER is used, and the running is less than or equal to a preset value; a second condition, the CG Retx timer is running and not overtime, a preset timer is used and the preset timer is not overtime either; conditional three, the CG Retx timer is running and not time out, using a preset timer, but not limited to whether the preset timer times out, that is, the preset timer may or may not time out at time t 8. The fourth condition, that is, the CG Retx timer is running and not overtime, uses COUTNER, but does not limit the relationship between COUTNER and the preset value, that is, the COUTNER may be greater than or equal to or less than the preset value at time t 8.

It should be understood that no matter which of the above four conditions, if the terminal device receives the DFI sent by the network device as ACK, it considers that the network device has correctly received the data, and therefore, the terminal device may suspend the CG Retx timer, and at the same time, the terminal device may also suspend the COUTNER or preset the timer.

Specifically, the first process in the embodiment of the present application may include at least one of the following steps: the terminal equipment determines the data transmission block capable of flushing in the target HARQ process; the terminal equipment determines that the data transmission block in the target HARQ process is successfully transmitted; the terminal equipment overturns a New Data Indication (NDI) in the target HARQ process; the terminal equipment determines that the target HARQ process is used for new transmission of data; the terminal equipment indicates the uplink resource to the target HARQ; the terminal equipment restarts the CG Retx timer; the terminal device resets the COUTNER or a preset timer.

This second process in the embodiments of the present application may include at least one of the following steps: pause the CG Retx timer; the terminal equipment determines that the data transmission block in the target HARQ process can be deleted; the terminal equipment determines that the data transmission block in the target HARQ process is successfully transmitted; the terminal equipment adopts a fourth CG resource in the CG resource set to perform new data transmission; the terminal device determines the NDI to be turned over at the time when the fourth CG transmission resource is available, or during the process of determining the new transmission of the data; the terminal device indicates the fourth CG transmission resource to the target HARQ process; restarting the CG Retx timer at a time when the fourth CG transmission resource is available; the COUTNER is reset at the time when the fourth CG transmission resource is available.

The fourth CG resource is any CG resource located after the first CG resource in the time domain, and the starting time of the fourth CG resource may be located before or after the CG Retx timer expires, which is not limited in this embodiment of the application. For example, the fourth CG resource may be a CG resource with a start time t10 as shown in fig. 3.

In case four, also for the time t8 after the time t5, if the CG Retx timer is running and not timed out, and if the terminal device receives the DCI sent by the network device and the DFI is Negative Acknowledgement (NACK) when the COUTNER is used and is less than or equal to the preset value, the terminal device may adopt the third CG resource in the CG resource set, retransmit the data on the first CG resource, restart the CG Retx timer, and add 1 to the COUTNER.

That is, if the terminal device receives the NACK indicating that the DFI sent by the network device is NACK, it may be determined that the network device has not correctly received the data. Therefore, the terminal device will pause the CG Retx timer; in addition, since COUTNER does not reach the preset value at time t8, the terminal device retransmits data on the first CG resource on the next CG resource in the CG resource set, that is, the third CG resource, and restarts the CG Retx timer; the terminal device further adds 1 to COUTNER to indicate the number of retransmissions of data on the third CG resource.

It should be understood that the starting time of the third CG resource is located after the starting time of the first CG resource; the starting time of the third CG resource may be before the CG Retx timer times out or after the CG Retx timer times out, and the embodiment of the present application is not limited thereto. For example, the third CG resource may be a CG resource with a start time t10 as shown in fig. 3.

In a fifth case, similar to the fourth case, also for a time t8 after the time t5, when the CG Retx timer is running and has not timed out, and the COUTNER used in limited use is less than or equal to a preset value, or the value of the COUTNER is not limited, if the terminal device receives DCI sent by the network device and the DFI is NACK, the terminal device may use a third CG resource in the CG resource set to retransmit data on the first CG resource, and restart the CG Retx timer and the COUTNER, that is, start the CG Retx timer to start a new round of timing, and start the COUTNER to start a new round of counting. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

That is, if the terminal device receives the NACK indicating that the DFI sent by the network device is NACK, it may be determined that the network device has not correctly received the data. Therefore, the terminal device will pause the CG Retx timer; in addition, since the terminal device receives the feedback of the network device, the terminal device may also reset COUTNER, and retransmit the data on the first CG resource on the next CG resource in the CG resource set, that is, on the third CG resource, and restart the CG Retx timer and COUTNER, that is, start the CG Retx timer to start a new round of timing, and start the COUTNER to start a new round of counting.

In a sixth case, also for a time t8 after the time t5, the CG Retx timer is running and is not timed out, at this time, without limiting the value of the COUTNER, if the terminal device receives that the DFI sent by the network device is NACK, the terminal device may add 1 to COUTNER, and determine whether to adopt the third CG resource, retransmit the data on the first CG resource, and restart the CG Retx timer when retransmitting. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

Specifically, since the current value of COUTNER is not limited, at time t8, the COUTNER may or may not have reached the preset value. Optionally, if the COUTNER does not reach the preset value at time t8, the terminal device receives the NACK, may retransmit the data using the third CG resource, and restart the CG Retx timer and add 1 to the COUTNER.

If the COUTNER has reached the preset value at time t8, that is, the COUTNER is equal to the preset value, the terminal device may add 1 to the COUTNER when receiving NACK, that is, the terminal device may select to suspend the CG Retx timer and not retransmit the data on the first CG resource. Specifically, for the case that the value of COUTNER is greater than a preset value, the terminal device may suspend the CG Retx timer and perform the first procedure or the second procedure when receiving the NACK; alternatively, the terminal device may not pause the CG Retx timer when receiving the NACK, and may perform the first procedure or the second procedure until the CG Retx timer times out. The first process and the second process are the first process and the second process in case three, and are not described herein again for brevity.

The above cases four to six are explained for the case of using COUTNER, and correspondingly, if a preset timer is used, there are the following cases seven to nine.

In a seventh case, similarly to the fourth case, for a time t8 after the time t5, the CG Retx timer is running and is not overtime, and in a case that a used preset timer is also running and is not overtime, if the terminal device receives that the DFI sent by the network device is NACK, the terminal device determines to adopt a third CG resource in the CG resource set, retransmits the data on the first CG resource, restarts the CG Retx timer, and otherwise, does not reset the preset timer, and keeps the preset timer to continue timing. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

That is, if the terminal device receives the NACK indicating that the DFI sent by the network device is NACK, it may be determined that the network device has not correctly received the data. Therefore, the terminal device will pause the CG Retx timer; in addition, since the preset timer is running at the time t8 and is not timed out, the terminal device retransmits the data on the first CG resource on the next CG resource in the CG resource set, that is, the third CG resource, and restarts the CG Retx timer while keeping the preset time for timing.

Case eight, similarly to case five, also for the case where the CG Retx timer is running and has not timed out at time t8 after time t5, and the preset timer defined for use has not timed out; or at time t8, if the CG Retx timer is running and not overtime, but without limiting whether the preset timer is overtime, if the terminal device receives DCI sent by the network device and the DFI is NACK, the terminal device may retransmit the data on the first CG resource by using a third CG resource in the CG resource set, and restart the CG Retx timer and the preset timer. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

That is, if the terminal device receives the NACK indicating that the DFI sent by the network device is NACK, it may be determined that the network device has not correctly received the data. Therefore, the terminal device will pause the CG Retx timer; in addition, since the terminal device receives the feedback from the network device, the terminal device may also pause the preset timer, and retransmit the data on the first CG resource on the next CG resource in the CG resource set, that is, on the third CG resource, and restart the CG Retx timer and the preset timer.

In case nine, similarly to case six, also for the time t8 after the time t5, if the CG Retx timer is running and has not timed out, and if the terminal device receives that the DFI sent by the network device is NACK without limiting whether the preset timer has timed out, the terminal device may determine whether to adopt a third CG resource in the CG resource set, retransmit the data on the first CG resource, and restart the CG Retx timer when retransmitting.

Specifically, since it is not limited whether the preset timer expires at time t8, the preset timer may or may not have expired at time t 8. Alternatively, if the preset timer does not time out at time t8, the terminal device receives NACK, and may retransmit the data using the third CG resource, and restart the CG Retx timer and keep the preset timer running.

If the predetermined timer has expired at time t8, then the terminal device may choose to pause the CG Retx timer if the terminal device receives a NACK, and no further retransmission of data on the first CG resource is performed. Specifically, for the case that the preset timer is overtime, the terminal device may suspend the CG Retx timer and perform the first procedure or the second procedure when receiving the NACK; alternatively, the terminal device may not pause the CG Retx timer when receiving the NACK, and may perform the first procedure or the second procedure until the CG Retx timer times out. The first process and the second process are the first process and the second process in case three, and are not described herein again for brevity.

In case ten, at time t9 after time t5, the CG Retx timer times out, that is, between time t5 and time t9, the terminal device does not receive the DFI and does not receive the indication information of the dynamic resource until time t9, and the CG Retx timer times out. At this time, if the used COUTNER is less than or equal to the preset value, the terminal device retransmits the data on the first CG resource by using the third CG resource, restarts the CG Retx timer, and adds 1 to the COUTNER. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

In case eleven, similarly to the case eleven, also at the time t9, the CG Retx timer times out, and for the case where the preset timer is used, and assuming that the preset timer is running and has not timed out, the terminal device uses the third CG resource, retransmits the data on the first CG resource, and restarts the CG Retx timer. The third CG resource is the third CG resource described in case four, and for brevity, will not be described herein again.

In the twelfth case, also at the time t9 after the time t5, the CG Retx timer times out, and for the case of using the COUTNER, if the COUTNER is greater than or equal to the preset value, the terminal device executes the first procedure or the second procedure. The first process and the second process are the first process and the second process in case three, and are not described herein again for brevity.

Thirteenth, similarly to the twelfth case, also at the time t9 after the time t5, the CG Retx timer times out, and for the case of using the preset timer, if the preset timer also times out, that is, the time when the preset timer times out is earlier than the CG Retx timer timeout time t9, the terminal device may execute the first procedure or the second procedure after the CG Retx timer times out. The first process and the second process are the first process and the second process in case three, and are not described herein again for brevity.

In a fourteenth case, for a time t9 after the time t5, assuming that the time t9 represents that the preset timer has expired and it is not limited whether the CG Retx timer has expired at this time, the terminal device may execute the first procedure or the second procedure when the preset timer at the time t9 has expired. The first process and the second process are the first process and the second process in case three, and are not described herein again for brevity.

That is, regardless of whether the CG Retx timer times out, the terminal device may select to perform the first procedure or the second procedure as long as the preset timer times out.

It should be understood that, as for any one of the timers (for example, any one of the CG timer, the CG Retx timer, and the preset timer) referred to in the embodiments of the present application, it may be any kind of timer, for example, the timer may adopt a gradually increasing timing manner from zero, and when the preset duration is reached, the timer is over-timed; or, the timer may also start to decrease gradually from a preset duration in a countdown manner, and when the time decreases to zero, the timer is overtime, which is not present in the embodiment of the present application.

It should be understood that, in the method 200 in the embodiment of the present application, the CG timer is for a dynamic resource, and the CG Retx timer is for a CG resource, and conversely, if the CG timer is set for a CG resource, and the CG Retx timer is set for a dynamic resource, the same may be true, and the embodiment of the present application is not limited thereto. That is, all of the dynamic resources in the method 200 may be replaced with CG resources, and all of the CG resources in the method 200 may be replaced with dynamic resources, which may be applied as well.

Therefore, in the method for transmitting data according to the embodiment of the present application, especially for an NR-U scenario, when two timers (CG timer and CG Retx timer) are configured for a given HARQ process configured for a CG resource, timing is performed for a dynamic resource and the CG resource respectively, and the two timers are not simultaneously involved in a car sickness, so that a behavior of how the terminal device uses the two timers is defined. Meanwhile, in order to avoid the problem of executing automatic retransmission for unlimited times, a counter or a timer is introduced in the retransmission process to limit the times of automatic retransmission, so that the problem that the air interface resource is wasted due to the fact that TB which does not meet the QoS still needs to be transmitted and occupies the air interface resource inefficiently is solved.

It should be understood that, in the various embodiments of the present application, neither the size of the serial numbers of the above-mentioned processes nor the reference number of the time t on the time axis imply the execution sequence, and the execution sequence of the processes should be determined by their functions and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
