[0028] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] To facilitate a better understanding of the embodiments of the present application, the CG enhancement in URLLC, the relevant background of NRU, and the CG enhancement in NRU are first described below.

[0030] CG enhancement in URLLC:

[0031] (1) In order to support the high latency requirements of URLLC services, the CG cycle is enhanced for URLLC services, that is, it supports service cycles at any slot level.

[0032] (2) In order to support various URLLC service scenarios and high latency requirements of URLLC services, multiple CG configurations are introduced for URLLC, namely CG resources. Different CG configurations have different HARQ processes, where the parameter harq-ProcID-Offset2 can be used to ensure that the HARQ processes of different CG configurations are different.

[0033] (3) Due to the conflict between CG resources and other resources, in order to ensure that the Media Access Control Control Element (MAC) Protocol Data Unit (PDU) that has been packaged in the CG resources is not discarded or transmitted as soon as possible, automatic transmission of CG resources (i.e., data on CG resources) is introduced. For the CG resources that package the MAC PDU and cannot be transmitted due to resource conflicts, the CG resources of the subsequent same HARQ process and with the same CG configuration as the CG resources can be used for automatic transmission of data. The use of automatic transmission can be determined by the parameter autonomousTx.

[0034] NRU related background:

[0035] NRU includes the following work scenarios:

[0036] Scenario A: Carrier aggregation scenario, the primary cell (PCell) corresponds to the authorized spectrum, and the secondary cell (SCell) corresponds to the NRU.

[0037] Scenario B: Dual-connection working scenario, PCell corresponds to LTE authorized spectrum, and primary secondary cell (PScell) corresponds to NRU.

[0038] Scenario C: Independent working scenario, an independent cell works on NRU.

[0039] Scenario D: NR single-cell scenario, the uplink (UL) works on the licensed spectrum and the downlink (DL) works on the NRU;

[0040] Scenario E: Dual-connectivity working scenario, PCell corresponds to NR licensed spectrum, and PScell ​​corresponds to NRU.

[0041] Generally speaking, the operating frequency bands of NRU are 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. In the unlicensed spectrum, the design of NRU should ensure fairness with other systems that have already worked in these unlicensed spectrums, such as Wireless Fidelity (WiFi). The principle of fairness is that the impact of NRU on systems that have already been deployed in the unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

[0042] In order to ensure fair coexistence between systems on the unlicensed spectrum, energy detection has been agreed upon as a basic coexistence mechanism. The general energy detection mechanism is the Listen Before Talk (LBT) mechanism. The basic principle of this mechanism is that before a network device or terminal device, as a transmitter, transmits data on the unlicensed spectrum, it needs to listen for a period of time as specified. If the listening result indicates that the channel is idle, the transmitter can transmit data to the receiver. If the listening result indicates that the channel is occupied, the transmitter needs to back off for a period of time according to the regulations and continue to listen to the channel until the channel listening result shows that it is idle before transmitting data to the receiver.

[0043] CG enhancements in NRU:

[0044] (1) For flexible resource selection, the HARQ process of the NRU CG is not calculated according to a formula, but is selected by the terminal device itself. For a CG resource, the network device configures a HARQ process set for the CG resource through Radio Resource Control (RRC) signaling, and the terminal device can select a HARQ process from the set for this CG transmission. The HARQ process set can be determined by the parameters harq-ProcID-Offset and nrofHARQ-Processes.

[0045] (2) NRU introduces multiple CG configurations, where multiple CG configurations can share the HARQ process.

[0046] (3) The CG retransmission timer (cg-Retransmission Timer) is introduced to support data transmission triggered when the CG resource cannot be transmitted due to LBT failure. After the cg-RetransmissionTimer times out, if the CG timer (configured Grant Timer) has not timed out, the data on the corresponding HARQ process or CG resource can be transmitted.

[0047] The data transmission on the CG resource can be interrupted by the dynamic scheduling DCI and DFI. The details are shown in Table 1:

[0048] Table 1

[0049]

[0050] As mentioned above, R17 considers supporting URLLC services in NRU scenarios. However, the configuration method of URLLC CG resources is different from the configuration method of the above-mentioned NRU CG resources. Therefore, in this case, how to determine whether to process the data on the URLLC CG resources and / or NRU CG resources, such as whether to perform automatic transmission, is a technical problem to be solved in this application.

[0051] It should be noted that the technical solution of the present application is not only applicable to the NRU system, but the embodiments of the present application can also be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, NR system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), WiFi, next generation communication system or other communication systems, etc.

[0052] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (Device to Device, D2D) communication, machine to machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), and vehicle to vehicle (Vehicle to Vehicle, V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0053] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0054] The embodiments of the present application do not limit the spectrum to which they are applied. For example, the embodiments of the present application can be applied to authorized spectrum or unauthorized spectrum. Accordingly, the resources to be referred to below in the present application can be NRU resources or authorized spectrum resources, and the present application does not limit this.

[0055] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located in the coverage area.

[0056] Figure 1 One network device and two terminal devices are shown exemplarily. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0057] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0058] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0059] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0060] The embodiments of the present application describe various embodiments in combination with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, for example, a terminal device in an NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0061] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0062] The network device can be a device used to communicate with a mobile device.

[0063] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell may be a cell corresponding to a network device (e.g., a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: a metro cell, a micro cell, a picocell, a femtocell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0064] In addition, the resources involved in this application can be CG resources or dynamic configuration (DynamicConfigure, DG) resources, and this application does not impose any restrictions on this.

[0065] Embodiment 1

[0066] Figure 2 The present invention provides a wireless communication method interaction flow chart according to an embodiment of the present invention, wherein the method comprises the following steps:

[0067] Step S210: The network device sends indication information to the terminal device. The indication information is an ACK / NACK indication of at least one HARQ process, and the HARQ process is a HARQ process corresponding to the first resource and / or the second resource, wherein the first resource and the second resource are configured differently.

[0068] Step S220: the terminal device processes or does not process the data transmission on the second resource according to the indication information, and / or processes the data transmission on the first resource according to the indication information.

[0069] Optionally, the function of the indication information is any of the following, but not limited to:

[0070] The indication information is an ACK / NACK indication for at least one HARQ process of one carrier.

[0071] The indication information is an ACK / NACK indication for at least one HARQ process of multiple carriers.

[0072] The indication information is an ACK / NACK indication for at least one HARQ process of a partial bandwidth (Bandwidth Part, BWP).

[0073] The indication information is an ACK / NACK indication for at least one HARQ process of multiple BWPs.

[0074] It should be noted that the ACK / NACK indication of at least one HARQ process refers to the ACK / NACK indication of each of the at least one HARQ process.

[0075] Optionally, the network device may be configured with only the first resource or the second resource for the terminal device.

[0076] Optionally, the network device may instruct to activate or use only the configured first resource or second resource.

[0077] Optionally, the network device may instruct to activate or use only the transmission mechanism corresponding to the configured first resource (ie, the third transmission mechanism hereinafter) or the transmission mechanism corresponding to the second resource (ie, the first transmission mechanism or the second transmission mechanism hereinafter).

[0078] Optionally, the network device may be configured with both the first resource and the second resource for the terminal device.

[0079] Optionally, the network device may instruct to activate or use the configured first resource and second resource simultaneously.

[0080] Optionally, the network device may instruct to simultaneously activate or use the transmission mechanism corresponding to the configured first resource (ie, the third transmission mechanism hereinafter) and the transmission mechanism corresponding to the second resource (ie, the first transmission mechanism or the second transmission mechanism hereinafter).

[0081] It should be understood that, in the present application, the HARQ process corresponding to the first resource is also described as the HARQ process corresponding to the first resource only.

[0082] It should be understood that, in the present application, the HARQ process corresponding to the second resource is also described as the HARQ process corresponding to the second resource only.

[0083] It should be understood that the HARQ process corresponding to the first resource and the second resource is also described as a HARQ process shared by the first resource and the second resource.

[0084] Optionally, the first resource may be an NRU CG resource, and the second resource may be a URLLC CG resource, but is not limited thereto. In the present application, as long as the configuration methods of the first resource and the second resource are different, it will suffice.

[0085] The so-called NRU CG resources refer to any CG resources under NRU, or CG resources configured by R16 NRU configuration mode / parameters, or CG resources configured by NRU configuration mode / parameters after R16. The so-called URLLC CG resources refer to any CG resources corresponding to URLLC services under NR or NRU, or CG resources configured by R16 NR configuration mode / parameters, or CG resources configured by NR / NRU configuration mode / parameters after R16, where the configuration methods of NRU CG resources and URLLC CG resources are different.

[0086] It should be noted that NRU CG resources can also carry URLLC services. In this case, the CG resources corresponding to the URLLC services are not referred to as URLLC CG resources. That is, in this application, the URLLC CG resources must meet the conditions that their configuration mode is different from the configuration mode of the NRU CG resources.

[0087] The following is an exemplary description of the different configuration methods of NRU CG resources and URLLC CG resources, but is not limited to this:

[0088] Exemplarily, for NRU CG resources, at least one of the following parameters is not configured: harq-ProcID-Offset2, redundant version number repK_RV during repeated transmission, autonomousTX. At least one of the following parameters is configured: harq-ProcID-Offset, cg-RetransmissionTimer. For URLLC CG resources, at least one of the following parameters is not configured: harq-ProcID-Offset, cg-RetransmissionTimer. At least one of the following parameters is configured: harq-ProcID-Offset2, repK_RV, autonomousTX.

[0089] Among them, harq-ProcID-Offset2 and autonomousTX are parameters in the CG enhancement in URLLC. harq-ProcID-Offset2 can ensure that the HARQ processes of different CG configurations are different. autonomousTX is used to determine the use of automatic transmission. repK_RV is used to determine the redundant version (Redundancy Version, RV) during repeated transmission. harq-ProcID-Offset and cg-RetransmissionTimer are parameters in the CG enhancement in NRU. harq-ProcID-Offset is used to determine the HARQ process set, and cg-RetransmissionTimer represents the CG retransmission timer. As mentioned above, after the CG retransmission timer times out, if the CG timer has not timed out, the data on the corresponding HARQ process or CG resource can be transmitted.

[0090] Exemplarily, assume that there are 5 CG resources, CG1, CG2 and CG3 with indexes 1, 2 and 3 respectively, which are all NRUCG resources, and CG4 and CG5 with indexes 4 and 5, which are all URLLC CGs. For CG1, CG2 and CG3, they are all configured with parameters configured Grant Timer, cg-RetransmissionTimer and HARQ process ID, where configured Grant Timer represents the CG timer, the meaning of cg-RetransmissionTimer can refer to the above definition of cg-RetransmissionTimer, and HARQ process ID represents the HART process identifier. Optionally, CG1 and CG2 can share the HARQ process ID, and CG3 does not share the HARQ process ID with CG1 and CG2. For CG4 and CG5, they are all configured with configured Grant Timer, HARQ process ID and autonomousTX. The definition of each parameter here can refer to the above content, which will not be repeated here. Optionally, the HARQ process IDs corresponding to CG4 and CG5 may be different.

[0091] Optionally, the terminal device processes data transmission on the second resource according to the indication information, including but not limited to: the terminal device transmits data on the second resource according to the indication information, or the terminal device does not transmit data on the second resource, that is, determines not to transmit data on the second resource.

[0092] Optionally, the terminal device may not transmit the data on the second resource according to the indication information, or the terminal device may ignore the indication information for the data on the second resource.

[0093] Optionally, the terminal device processes data transmission on the first resource according to the indication information, including but not limited to the following situations: the terminal device transmits data on the first resource according to the indication information, or the terminal device does not transmit data on the first resource, that is, determines not to transmit data on the first resource.

[0094] Optionally, the terminal device may not transmit the data on the first resource according to the indication information, or the terminal device may ignore the indication information for the data on the first resource.

[0095] In summary, in the present application, when the terminal device is configured with a first resource and a second resource at the same time, the terminal device can determine whether to process the data transmission of the first resource based on the above-mentioned indication information, and / or process the data transmission on the first resource based on the indication information.

[0096] Embodiment 2

[0097] The following is a detailed description of the processing of the data transmission on the first resource by the terminal device according to the indication information in the above step S220:

[0098] Optionally, the terminal device processes the data transmission on the first resource according to the indication information, which may be implemented in the following manner, but is not limited thereto:

[0099] The terminal device processes the data transmission on the first resource according to the third transmission mechanism according to the indication information, and the third transmission mechanism is the transmission mechanism of the first resource. Of course, the terminal device can process the data transmission on the first resource according to other transmission mechanisms, such as the first transmission mechanism or the second transmission mechanism, the first transmission mechanism is the automatic transmission mechanism of the second resource, and the second transmission mechanism is the enhanced automatic transmission mechanism of the second resource. This application does not limit what transmission mechanism the terminal device uses to process the data transmission on the first resource.

[0100] Optionally, when the second resource is a URLLC CG resource, the first transmission mechanism may be an automatic transmission mechanism in R16, wherein the automatic transmission mechanism in R16 uses the same HARQ process as the second resource and resources with the same configuration (ie, CG configuration) to automatically transmit data.

[0101] Optionally, the terminal device may process the data transmission on the first resource according to the first transmission mechanism according to the indication information in the following optional ways, but is not limited thereto:

[0102] Option 1: If the indication information includes a NACK indication of the second HARQ process corresponding to the first resource, the terminal device transmits the data on the first resource according to the first transmission mechanism. If the indication information includes an ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0103] Option 2: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the second HARQ process, and the first resource is a resource for data transmission determined according to a priority rule among the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the first resource according to the first transmission mechanism. If the indication information includes an ACK indication of the first resource, the terminal device does not transmit the data on the first resource.

[0104] Optional method three: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the second HARQ process, and the PDU on the first resource is the PDU to be transmitted according to the priority rule among the PDUs on the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the first resource according to the first transmission mechanism. If the indication information includes an ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0105] Option 4: If the indication information includes NACK indications of multiple HARQ processes, one HARQ process is selected as the second HARQ process from the multiple HARQ processes, and the terminal device transmits the data on the first resource according to the first transmission mechanism. If the indication information includes ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0106] Among them, optional method 1 is for the case where the indication information only includes the NACK indication of the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource. Optional methods 2 to 4 are for the case where the indication information includes the NACK indication of multiple HARQ processes, wherein the multiple HARQ processes include the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource.

[0107] It should be noted that the “transmission” in the above-mentioned optional methods 1 to 4 is also described as “automatic transmission” or “automatic retransmission”.

[0108] The following are descriptions of the four optional methods:

[0109] Description of optional method 1: When the indication information includes a NACK indication of the second HARQ process corresponding to the first resource, it indicates that the data reception on the first resource has failed, and the terminal device needs to automatically transmit the data on the first resource. The terminal device can automatically transmit data according to the first transmission mechanism. When the indication information includes an ACK indication of the second HARQ process corresponding to the first resource, it indicates that the data reception on the first resource has been successful, and the terminal device does not need to automatically transmit the data on the first resource.

[0110] Optional method 2 is described below: Assuming that the first resource is an NRU CG resource, the above multiple HARQ processes have the following situations:

[0111] Case 1: Multiple HARQ processes include: HARQ processes corresponding to multiple NRU CG resources.

[0112] Case 2: Multiple HARQ processes include: a HARQ process corresponding to at least one NRU CG resource, and at least one other HARQ process.

[0113] The other HARQ processes here can be any of the following: the HARQ process corresponding to the URLLC CG resources, and the HARQ process shared by the URLLCCG resources and the NRU CG resources.

[0114] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the resource determined according to the first transmission mechanism is unique, and the resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource that needs to automatically transmit data according to the priority rule. Here, when the above-mentioned first resource is the resource that the terminal device selects according to the priority rule for automatic data transmission, the terminal device transmits the data on the first resource according to the first transmission mechanism. It should be noted that the number of times the resource is determined for automatically transmitting the above-mentioned data is not limited. In other words, for one HARQ process or resource, automatic transmission can occur multiple times.

Here, when the above-mentioned first resource is the resource corresponding to the PDU that needs to automatically transmit data selected by the terminal device according to the PDU priority rule, the terminal device transmits the data on the first resource according to the first transmission mechanism. It should be noted that the number of times the resource is determined for automatically transmitting the above-mentioned data is not limited. In other words, for a HARQ process or resource, automatic transmission can occur multiple times.

In Optional Method 1, the indication information only includes the NACK indication of the second HARQ process, or includes the ACK indication of the second HARQ process. Therefore, its content can refer to Optional Method 1, and it will not be repeated here.

[0122] Optionally, when the second resource is a URLLC CG resource, the second transmission mechanism may be an enhanced automatic transmission mechanism in R17, wherein the enhanced automatic transmission mechanism in R17 uses a HARQ process different from that of the second resource, and / or a resource with a different configuration (i.e., CG configuration) for automatic data transmission.

If the indication information includes ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0128] Among them, optional method 1 is for the case where the indication information only includes the NACK indication of the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource. Optional methods 2 to 4 are for the case where the indication information includes the NACK indication of multiple HARQ processes, wherein the multiple HARQ processes include the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource.

In Optional Method 1, the indication information only includes the NACK indication of the second HARQ process, or includes the ACK indication of the second HARQ process. Therefore, its content can refer to Optional Method 1, and it will not be repeated here.

[0144] Optionally, the third transmission mechanism is to use the first resource (i.e., the seventh resource in this application) after receiving the indication information to automatically transmit data. Based on this, the seventh resource is the resource whose data transmission time is closest to the reception time of the indication information after receiving the indication information. Optionally, the seventh resource is an available / valid resource, or a resource when LBT is successful.

[0145] It should be understood that the third transmission mechanism is also described as using the first available / valid first resource after receiving the indication information for automatic data transmission. Alternatively, the third transmission mechanism is using the latest resource after receiving the indication information for automatic data transmission. Alternatively, the third transmission mechanism is using the latest available / valid resource after receiving the indication information for automatic data transmission.

[0146] Optionally, the seventh resource is a resource that shares the first HARQ process with the first resource and has the same or different configuration as the first resource. Alternatively, the seventh resource is a resource that has a different configuration from the first resource.

[0147] Exemplarily, when the first resource is an NRU CG resource, the seventh resource is also an NRU CG resource.

[0148] Optionally, when the first resource is an NRU CG resource, the third transmission mechanism is to use the first NRU resource after receiving the indication information for automatic data transmission. Alternatively, the third transmission mechanism is to use the first available / valid first NRU resource after receiving the indication information for automatic data transmission.

If the indication information includes an ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0151] Option 2: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the second HARQ process, and the first resource is a resource for data transmission determined according to a priority rule among the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the first resource according to the third transmission mechanism. If the indication information includes an ACK indication of the first resource, the terminal device does not transmit the data on the first resource.

[0152] Optional method three: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the second HARQ process, and the PDU on the first resource is the PDU to be transmitted according to the priority rule among the PDUs on the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the first resource according to the third transmission mechanism.

If the indication information includes ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource.

[0154] Among them, optional method 1 is for the case where the indication information only includes the NACK indication of the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource. Optional methods 2 to 4 are for the case where the indication information includes the NACK indication of multiple HARQ processes, wherein the multiple HARQ processes include the second HARQ process, or the indication information includes the ACK indication of the second HARQ process, to introduce how the terminal device processes the data transmission on the first resource.

[0155] It should be noted that the “transmission” in the above-mentioned optional methods 1 to 4 is also described as “automatic transmission” or “automatic retransmission”.

[0156] The following are descriptions of the four optional methods:

[0157] Description of optional method 1: When the indication information includes a NACK indication of the second HARQ process corresponding to the first resource, it indicates that the data reception on the first resource has failed, and the terminal device needs to automatically transmit the data on the first resource. The terminal device can automatically transmit data according to the third transmission mechanism. When the indication information includes an ACK indication of the second HARQ process corresponding to the first resource, it indicates that the data reception on the first resource has been successful, and the terminal device does not need to automatically transmit the data on the first resource.

[0158] Optional method 2 is described below: Assuming that the first resource is an NRU CG resource, the above multiple HARQ processes have the following situations:

[0159] Case 1: Multiple HARQ processes include: HARQ processes corresponding to multiple NRU CG resources.

[0160] Case 2: Multiple HARQ processes include: a HARQ process corresponding to at least one NRU CG resource, and at least one other HARQ process.

[0161] The other HARQ processes here can be any of the following: the HARQ process corresponding to the URLLC CG resources, and the HARQ process shared by the URLLCCG resources and the NRU CG resources.

[0162] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the seventh resource determined according to the third transmission mechanism is unique, and the seventh resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource that needs to automatically transmit data according to the priority rule. Here, when the above-mentioned first resource is the resource that the terminal device selects according to the priority rule for automatic data transmission, the terminal device transmits the data on the first resource according to the third transmission mechanism. It should be noted that the number of times the seventh resource is determined is not limited. In other words, there can be multiple automatic transmissions for one HARQ process or resource.

[0163] Optionally, the above priority rules include any of the following, but are not limited to: a physical layer priority rule, a logical channel priority rule, or a priority rule for a resource type.

[0164] Optionally, when the indication information includes an ACK indication of the second HARQ process corresponding to the first resource, it indicates that the data on the first resource is received successfully, and the terminal device does not need to automatically transmit the data on the first resource.

[0165] Description of Optional Method 3: For the description of multiple HARQ processes, please refer to the contents of Optional Method 2, and this application will not go into details.

[0166] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the seventh resource determined according to the third transmission mechanism is unique, and the seventh resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource corresponding to the PDU that needs to automatically transmit data according to the PDU priority rule. Here, when the above-mentioned first resource is the resource corresponding to the PDU that needs to automatically transmit data selected by the terminal device according to the PDU priority rule, the terminal device transmits the data on the first resource according to the third transmission mechanism. It should be noted that there is no limit on the number of times the seventh resource is determined. In other words, there can be multiple automatic transmissions for one HARQ process or resource.

[0167] Optionally, the above-mentioned PDU priority rules include any of the following items, but are not limited to: priority rules for transmission according to the identification size of the PDU, priority rules for transmission according to the length of the PDU, priority rules for transmission according to the size of the data carried by the PDU, and priority rules determined according to the priority of the logical channel in the PDU.

[0168] Optionally, when the indication information includes an ACK indication of the second HARQ process corresponding to the first resource, it indicates that the data on the first resource is received successfully, and the terminal device does not need to automatically transmit the data on the first resource.

[0169] Description of Optional Method 4: The difference between Optional Method 4 and Optional Method 1 is that: in Optional Method 4, the indication information includes NACK indications of multiple HARQ processes, or includes ACK indications of the second HARQ process, and the multiple HARQ processes include the second HARQ process, but the second HARQ process is a HARQ process randomly selected by the terminal device. In Optional Method 1, the indication information only includes the NACK indication of the second HARQ process, or includes the ACK indication of the second HARQ process. Therefore, its content can refer to Optional Method 1, and it will not be repeated here.

[0170] It should be noted that when the terminal device transmits data on the first resource according to the third transmission mechanism, the terminal device can also stop the cg-Retransmission Timer, and when performing automatic transmission, the cg-Retransmission Timer can be restarted. When the terminal device does not transmit data on the first resource, the terminal device can stop the cg-Retransmission Timer and the configured Grant Timer. When the terminal device receives the indication information, the terminal device can stop the cg-Retransmission Timer.

[0171] As an example, if the second process corresponds to the second resource and the first resource, the terminal device may also process or not process the data transmission on the first resource according to one of the first transmission mechanism, the second transmission mechanism, or the third transmission mechanism.

[0172] As another example, if the second process corresponds to the second resource and the first resource, the terminal device may also process or not process the data transmission on the first resource according to the indication information and the data transmission method on the third resource before receiving the indication information.

[0173] Exemplarily, if the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an NRU CG resource, the shared second HARQ process of the first resource and the second resource is understood according to the HARQ process of the first resource, that is, the data transmission method of the first resource is the same as the data transmission method of the third resource. In this case, the terminal device processes the data on the first resource. If the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an URLLC CG resource, the shared second HARQ process of the first resource and the second resource is understood according to the HARQ process of the second resource. In this case, the terminal device does not process the data on the first resource.

[0174] Exemplarily, if the NRU CG and URLLC CG configuration parameters or methods are configured at the same time, and if the first resource is an NRUCG resource, the second resource is a URLLC CG resource, and the third resource is also a CG resource, the first resource and the second resource share the second HARQ process. In this case, if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the NRU CG resource transmission method, the third resource is transmitted in accordance with the NRU CG transmission method; if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the URLLC CG resource transmission method, the third resource is transmitted in accordance with the URLLC CG transmission method.

[0175] It should be understood that in the present application, if the indication information includes an ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource, which can also be described as: if the indication information includes an ACK indication of the second HARQ process, the terminal device does not transmit the data on the first resource according to the third transmission mechanism.

[0176] In summary, in the present application, the terminal device can process the data on the first resource according to the above indication information.

[0177] Embodiment 3

[0178] The following is a detailed description of whether the terminal device processes or does not process the data transmission on the second resource according to the indication information in the above step S220:

[0179] Optionally, if the first HARQ process corresponds to the second resource, the terminal device does not process the data transmission on the second resource, or the terminal device ignores the indication information; if the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission method on the third resource before receiving the indication information.

[0180] Optionally, the third resource is a resource whose data transmission time is closest to the reception time of the indication information before the indication information is received.

[0181] It should be understood that the third resource can also be described as an available / valid resource whose data transmission time is closest to the reception time of the indication information before the indication information is received. Alternatively, the third resource is the first resource before the indication information is received. Alternatively, the third resource is the first available / valid resource before the indication information is received. Alternatively, the third resource is the closest resource before the indication information is received. Alternatively, the third resource is the closest available / valid resource before the indication information is received. Optionally, the resource is an available / valid resource, or a resource when LBT is successful.

[0182] Exemplarily, if the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an NRU CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the first resource, in which case the terminal device does not process the data on the second resource. If the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an URLLC CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the second resource, in which case, when the first HARQ process corresponds to the second resource, the terminal device does not process the data transmission on the second resource, or the terminal device ignores the indication information.

[0183] Exemplarily, if the NRU CG and URLLC CG configuration parameters or methods are configured at the same time, and if the first resource is an NRUCG resource, the second resource is a URLLC CG resource, and the third resource is also a CG resource, the first resource and the second resource share the second HARQ process. In this case, if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the NRU CG resource transmission method, the third resource is transmitted in accordance with the NRU CG transmission method; if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the URLLC CG resource transmission method, the third resource is transmitted in accordance with the URLLC CG transmission method.

[0184] In summary, in the present application, if the first HARQ process corresponds to the second resource, the terminal device does not process the data transmission on the second resource, or the terminal device ignores the indication information, based on which the complexity of data processing by the terminal device can be reduced. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission mode on the third resource before receiving the indication information, so that it can be clear whether the second resource is processed, and, if it is processed, the data processing mode adopted.

[0185] Embodiment 4

[0186] The following is a detailed description of whether the terminal device processes or does not process the data transmission on the second resource according to the indication information in the above step S220:

[0187] Optionally, if the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the first transmission mechanism or the second transmission mechanism according to the indication information. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission mode on the third resource before receiving the indication information. Alternatively, if the first process corresponds to the second resource and the first resource, the terminal device may also process or not process the data transmission on the second resource according to one of the first transmission mechanism, the second transmission mechanism, or the third transmission mechanism.

[0188] Optionally, the terminal device may process the data transmission on the second resource according to the first transmission mechanism or the second transmission mechanism according to the indication information in the following optional ways, but is not limited thereto:

[0190] Option 2: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the first HARQ process, and the second resource is a resource for data transmission determined according to a priority rule among the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the second resource according to the first transmission mechanism or the second transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0191] Optional method three: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the first HARQ process, and the packet data unit PDU on the second resource is the PDU to be transmitted according to the priority rule among the PDUs on the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the second resource according to the first transmission mechanism or the second transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0192] Option 4: If the indication information includes NACK indications of multiple HARQ processes, one HARQ process is selected as the first HARQ process from the multiple HARQ processes, and the terminal device transmits the data on the second resource according to the first transmission mechanism or the second transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0193] It is worth mentioning that the first optional method is to introduce how the terminal device processes the data transmission on the second resource for the case where the indication information only includes the NACK indication of the first HARQ process, or the indication information includes the ACK indication of the first HARQ process. The second to fourth optional methods are to introduce how the terminal device processes the data transmission on the second resource for the case where the indication information includes the NACK indication of multiple HARQ processes, wherein the multiple HARQ processes include the first HARQ process, or the indication information includes the ACK indication of the first HARQ process.

[0194] It should be noted that the “transmission” in the above-mentioned optional methods 1 to 4 is also described as “automatic transmission” or “automatic retransmission”.

[0195] The following are descriptions of the four optional methods:

[0196] Description of optional method 1: When the indication information includes a NACK indication of the first HARQ process corresponding to the second resource, it indicates that the data reception on the second resource has failed, and the terminal device needs to automatically transmit the data on the second resource. The terminal device can automatically transmit data according to the first or second transmission mechanism. When the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data reception on the second resource has been successful, and the terminal device does not need to automatically transmit the data on the second resource.

[0197] For optional method 2, it is described as follows: Assuming that the second resource is a URLLC CG resource, the above multiple HARQ processes have the following situations:

[0199] Case 2: Multiple HARQ processes include: a HARQ process corresponding to at least one URLLC CG resource, and at least one other HARQ process.

[0200] The other HARQ processes here can be any of the following: the HARQ process corresponding to the NRU CG resources, and the HARQ process shared by the URLLC CG resources and the NRU CG resources.

[0201] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the resource determined according to the first transmission mechanism or the second transmission mechanism is unique, and the resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource that needs to automatically transmit data according to the priority rule. Here, when the second resource is the resource that the terminal device selects according to the priority rule for automatic data transmission, the terminal device transmits the data on the second resource according to the first transmission mechanism or the second transmission mechanism. It should be noted that there is no limit on the number of times the resource is determined for automatically transmitting the above data. In other words, there can be multiple automatic transmissions for one HARQ process or resource.

[0202] Optionally, the above priority rules include any of the following, but are not limited to: a physical layer priority rule, a logical channel priority rule, or a priority rule for a resource type.

[0203] Optionally, when the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data on the second resource is received successfully, and the terminal device does not need to automatically transmit the data on the second resource.

[0204] Description of Optional Method 3: For the description of multiple HARQ processes, please refer to the contents of Optional Method 2, and this application will not go into details.

[0205] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the resource determined according to the first or second transmission mechanism is unique, and the resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource corresponding to the PDU that needs to automatically transmit data according to the PDU priority rule. Here, when the above-mentioned second resource is the resource corresponding to the PDU that needs to automatically transmit data selected by the terminal device according to the PDU priority rule, the terminal device transmits the data on the second resource according to the first or second transmission mechanism. It should be noted that there is no limit on the number of times the resource is determined for automatically transmitting the above-mentioned data. In other words, for one HARQ process or resource, automatic transmission can occur multiple times.

[0206] Optionally, the above-mentioned PDU priority rules include any of the following items, but are not limited to: priority rules for transmission according to the identification size of the PDU, priority rules for transmission according to the length of the PDU, priority rules for transmission according to the size of the data carried by the PDU, and priority rules determined according to the priority of the logical channel in the PDU.

[0207] Optionally, when the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data on the second resource is received successfully, and the terminal device does not need to automatically transmit the data on the second resource.

[0208] Description of Optional Method 4: The difference between Optional Method 4 and Optional Method 1 is that: in Optional Method 4, the indication information includes NACK indications of multiple HARQ processes, or includes ACK indications of the first HARQ process, and the multiple HARQ processes include the first HARQ process, but the first HARQ process is a HARQ process randomly selected by the terminal device. In Optional Method 1, the indication information only includes the NACK indication of the first HARQ process, or includes the ACK indication of the first HARQ process. Therefore, its content can refer to Optional Method 1, and it will not be repeated here.

[0209] Optionally, the terminal device transmits data on the second resource according to the first transmission mechanism, including: the terminal device transmits data on the second resource using the first HARQ process and a fourth resource with the same configuration as the second resource.

[0210] That is, the fourth resource shares the first HARQ process with the second resource and has the same configuration as the second resource.

[0211] In this application, as long as the indexes of any two resources are the same, their configurations are the same.

[0212] Optionally, the configuration of a resource includes at least one of the following: the time-frequency position of the resource, information on whether frequency hopping is performed, etc.

[0213] Optionally, since there may be multiple resources that share the first HARQ process with the second resource and have the same configuration as the second resource or the resources may appear periodically, in the present application, the fourth resource is a resource that shares the first HARQ process with the second resource and has the same configuration as the second resource, and after receiving the indication information, the data transmission time is closest to the reception time of the indication information. It should be noted that the number of times the fourth resource is determined is not limited. That is, for one HARQ process or resource, there can be multiple automatic transmissions.

[0214] It should be understood that: the fourth resource can also be described as: the fourth resource is a resource that shares the first HARQ process with the second resource and has the same configuration as the second resource, and after receiving the indication information, the data transmission time is the closest available / valid resource to the reception time of the indication information. Alternatively, the fourth resource is the first resource after receiving the indication information in the resource that shares the first HARQ process with the second resource and has the same configuration as the second resource. Alternatively, the fourth resource is the first available / valid resource after receiving the indication information in the resource that shares the first HARQ process with the second resource and has the same configuration as the second resource. Alternatively, the fourth resource is the most recent resource after receiving the indication information in the resource that shares the first HARQ process with the second resource and has the same configuration as the second resource. Alternatively, the fourth resource is the most recent available / valid resource after receiving the indication information in the resource that shares the first HARQ process with the second resource and has the same configuration as the second resource. Optionally, the resource is an available / valid resource, or a resource when LBT is successful.

[0215] Exemplarily, when the second resource is a URLLC CG resource, the fourth resource here should also be a URLLC CG resource.

[0216] Optionally, the terminal device transmits data on the second resource according to the second transmission mechanism, including: the terminal device uses a HARQ process different from the first HARQ process, and / or a fifth resource configured differently from the second resource to transmit data on the second resource.

[0217] That is, the fifth resource and the second resource correspond to different HARQ processes, and / or the fifth resource and the second resource have different configurations.

[0218] Optionally, since there may be multiple or periodic occurrences of a first HARQ process different from the second resource and / or a resource with a different configuration from the second resource, in the present application, the fifth resource is a resource whose data transmission time is closest to the reception time of the indication information after receiving the indication information in a HARQ process different from the second resource and / or a resource with a different configuration from the second resource. It should be noted that the number of times the fifth resource is determined is not limited. That is, for one HARQ process or resource, automatic transmission can occur multiple times.

[0219] It should be understood that: the fifth resource can also be described as: the fifth resource is a HARQ process different from the second resource, and / or, in a resource with a different configuration from the second resource, after receiving the indication information, the data transmission time is the closest available / valid resource to the reception time of the indication information. Alternatively, the fifth resource can also be described as: the fifth resource is a HARQ process different from the second resource, and / or, in a resource with a different configuration from the second resource, the first resource after receiving the indication information. Alternatively, the fifth resource can also be described as: the fifth resource is a HARQ process different from the second resource, and / or, in a resource with a different configuration from the second resource, the first available / valid resource after receiving the indication information. Alternatively, the fifth resource is a HARQ process different from the second resource, and / or, in a resource with a different configuration from the second resource, the most recent resource after receiving the indication information. Alternatively, the fifth resource is a HARQ process different from the second resource, and / or, in a resource with a different configuration from the second resource, the most recent available / valid resource after receiving the indication information. Optionally, the resource is an available / valid resource, or a resource when LBT succeeds.

[0220] Exemplarily, when the second resource is a URLLC CG resource, the fifth resource here should also be a URLLC CG resource.

[0221] The following is a description of whether the terminal device processes or does not process the data transmission on the second resource according to the data transmission mode on the third resource before receiving the indication information if the first HARQ process corresponds to the second resource and the first resource:

[0222] Among them, the definition of the third resource can refer to Example 3, and this application will not explain it further.

[0223] Exemplarily, if the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an NRU CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the first resource, in which case the terminal device does not process the data on the second resource. If the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an URLLC CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the second resource, in which case, when the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the first transmission mechanism or the second transmission mechanism according to the indication information.

[0224] Exemplarily, if the NRU CG and URLLC CG configuration parameters or methods are configured at the same time, and if the first resource is an NRUCG resource, the second resource is a URLLC CG resource, and the third resource is also a CG resource, the first resource and the second resource share the second HARQ process. In this case, if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the NRU CG resource transmission method, the third resource is transmitted in accordance with the NRU CG transmission method; if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the URLLC CG resource transmission method, the third resource is transmitted in accordance with the URLLC CG transmission method.

[0225] It should be understood that in the present application, if the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource, which can also be described as: if the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource according to the first transmission mechanism or the second transmission mechanism.

[0226] In summary, in the present application, if the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the first transmission mechanism or the second transmission mechanism according to the indication information. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information according to the data transmission method on the third resource before receiving the indication information. Therefore, the indication information can be applied not only to the first resource, but also to the second resource, thereby expanding the scope of use of the indication information and introducing a non-adaptive data transmission indication method for the second resource to a certain extent.

[0227] Embodiment 5

[0228] The following is a detailed description of whether the terminal device processes or does not process the data transmission on the second resource according to the indication information in the above step S220:

[0229] Optionally, if the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the third transmission mechanism according to the indication information, and the third transmission mechanism is the transmission mechanism of the first resource. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission mode on the third resource before receiving the indication information. Alternatively, if the first process corresponds to the second resource and the first resource, the terminal device may also process or not process the data transmission on the second resource according to one of the first transmission mechanism, the second transmission mechanism, or the third transmission mechanism.

[0230] Optionally, if the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the third transmission mechanism and / or according to the indication information, and the third transmission mechanism is the transmission mechanism of the first resource. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission mode on the third resource before receiving the indication information.

[0231] Optionally, the terminal device may process the data transmission on the second resource according to the third transmission mechanism according to the indication information in the following optional ways, but is not limited thereto:

[0232] Option 1: If the indication information includes a NACK indication of the first HARQ process, the terminal device transmits the data on the second resource according to the third transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0233] Option 2: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the first HARQ process, and the second resource is a resource for data transmission determined according to a priority rule among the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the second resource according to the third transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0234] Option three: If the indication information includes NACK indications of multiple HARQ processes, the multiple HARQ processes include the first HARQ process, and the PDU on the second resource is the PDU to be transmitted according to the priority rule among the PDUs on the resources corresponding to the multiple HARQ processes, the terminal device transmits the data on the second resource according to the third transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0235] Option 4: If the indication information includes NACK indications of multiple HARQ processes, one HARQ process is selected as the first HARQ process from the multiple HARQ processes, and the terminal device transmits the data on the second resource according to the third transmission mechanism. If the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource.

[0236] It is worth mentioning that the first optional method is to introduce how the terminal device processes the data transmission on the second resource for the case where the indication information only includes the NACK indication of the first HARQ process, or the indication information includes the ACK indication of the first HARQ process. The second to fourth optional methods are to introduce how the terminal device processes the data transmission on the second resource for the case where the indication information includes the NACK indication of multiple HARQ processes, wherein the multiple HARQ processes include the first HARQ process, or the indication information includes the ACK indication of the first HARQ process.

[0237] It should be noted that the “transmission” in the above-mentioned optional methods 1 to 4 is also described as “automatic transmission” or “automatic retransmission”.

[0238] The following are descriptions of the four optional methods:

[0239] Description of optional method 1: When the indication information includes a NACK indication of the first HARQ process corresponding to the second resource, it indicates that the data reception on the second resource has failed, and the terminal device needs to automatically transmit the data on the second resource. The terminal device can automatically transmit data according to the third transmission mechanism. When the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data reception on the second resource has succeeded, and the terminal device does not need to automatically transmit the data on the second resource.

[0240] For optional method 2, it is described as follows: Assuming that the second resource is a URLLC CG resource, the above multiple HARQ processes have the following situations:

[0241] Case 1: Multiple HARQ processes include: HARQ processes corresponding to multiple URLLC CG resources.

[0242] Case 2: Multiple HARQ processes include: a HARQ process corresponding to at least one URLLC CG resource, and at least one other HARQ process.

[0243] The other HARQ processes here can be any of the following: the HARQ process corresponding to the NRU CG resources, and the HARQ process shared by the URLLC CG resources and the NRU CG resources.

[0244] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the resource determined according to the third transmission mechanism is unique, and the resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource that needs to automatically transmit data according to the priority rule. Here, when the second resource is the resource that the terminal device selects according to the priority rule for automatic data transmission, the terminal device transmits the data on the second resource according to the third transmission mechanism. It should be noted that the number of times the resource is determined for automatically transmitting the above data is not limited. In other words, there can be multiple automatic transmissions for one HARQ process or resource.

[0245] Optionally, the above priority rules include any of the following, but are not limited to: a physical layer priority rule, a logical channel priority rule, or a priority rule for a resource type.

[0246] Optionally, when the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data on the second resource is received successfully, and the terminal device does not need to automatically transmit the data on the second resource.

[0247] Description of Optional Method 3: For the description of multiple HARQ processes, please refer to the contents of Optional Method 2, and this application will not go into details.

[0248] Optionally, when the indication information includes NACK indications of multiple HARQ processes, since the resource determined according to the third transmission mechanism is unique, and the resource can only transmit data corresponding to one resource at a time, the terminal device can select the resource corresponding to the PDU that needs to automatically transmit data according to the PDU priority rule. Here, when the above-mentioned second resource is the resource corresponding to the PDU that needs to automatically transmit data selected by the terminal device according to the PDU priority rule, the terminal device transmits the data on the second resource according to the third transmission mechanism. It should be noted that the number of times the resource is determined for automatically transmitting the above-mentioned data is not limited. In other words, for one HARQ process or resource, automatic transmission can occur multiple times.

[0249] Optionally, the above-mentioned PDU priority rules include any of the following items, but are not limited to: priority rules for transmission according to the identification size of the PDU, priority rules for transmission according to the length of the PDU, priority rules for transmission according to the size of the data carried by the PDU, and priority rules determined according to the priority of the logical channel in the PDU.

[0250] Optionally, when the indication information includes an ACK indication of the first HARQ process corresponding to the second resource, it indicates that the data on the second resource is received successfully, and the terminal device does not need to automatically transmit the data on the second resource.

[0251] Description of Optional Method 4: The difference between Optional Method 4 and Optional Method 1 is that: in Optional Method 4, the indication information includes NACK indications of multiple HARQ processes, or includes ACK indications of the first HARQ process, and the multiple HARQ processes include the first HARQ process, but the first HARQ process is a HARQ process randomly selected by the terminal device. In Optional Method 1, the indication information only includes the NACK indication of the first HARQ process, or includes the ACK indication of the first HARQ process. Therefore, its content can refer to Optional Method 1, and it will not be repeated here.

[0252] Optionally, the terminal device transmits the data on the second resource according to the third transmission mechanism, including: the terminal device transmits the data on the second resource on the sixth resource after receiving the indication information.

[0253] Optionally, the sixth resource is a resource whose data transmission time is closest to the reception time of the indication information after the indication information is received.

[0254] It should be understood that: the sixth resource can also be described as: the sixth resource is the available / valid resource whose data transmission time is closest to the reception time of the indication information after the indication information is received. Or, the sixth resource is the first resource after the indication information is received. Or, the sixth resource is the first available / valid resource after the indication information is received. Or, the sixth resource is the most recent resource after the indication information is received. Or, the sixth resource is the most recent available / valid resource after the indication information is received. Optionally, the resource is an available / valid resource, or a resource when LBT is successful.

[0255] Optionally, the sixth resource is a resource that shares the first HARQ process with the second resource and has a different configuration from the second resource. That is, the sixth resource shares the first HARQ process with the second resource and has a different configuration from the second resource.

[0256] Exemplarily, when the second resource is a URLLC CG resource, the sixth resource here should be a NRU CG resource.

[0257] The following is a description of whether the terminal device processes or does not process the data transmission on the second resource according to the data transmission mode on the third resource before receiving the indication information if the first HARQ process corresponds to the second resource and the first resource:

[0258] Among them, the definition of the third resource can refer to Example 3, and this application will not explain it further.

[0259] Exemplarily, if the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an NRU CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the first resource, in which case the terminal device does not process the data on the second resource. If the first resource is an NRU CG resource, the second resource is an URLLC CG resource, and the third resource is also an URLLC CG resource, the shared first HARQ process of the first resource and the second resource is understood according to the HARQ process of the second resource, in which case, when the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the third transmission mechanism according to the indication information.

[0260] Exemplarily, if the NRU CG and URLLC CG configuration parameters or methods are configured at the same time, and if the first resource is an NRUCG resource, the second resource is a URLLC CG resource, and the third resource is also a CG resource, the first resource and the second resource share the second HARQ process. In this case, if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the NRU CG resource transmission method, the third resource is transmitted in accordance with the NRU CG transmission method; if the HARQ process corresponding to the third resource is a shared HARQ process, and the last resource transmission of the shared HARQ process is the URLLC CG resource transmission method, the third resource is transmitted in accordance with the URLLC CG transmission method.

[0261] Optionally, when the terminal device transmits data on the second resource according to the third transmission mechanism, the terminal device at least sends an identifier of the first HARQ process to the network device. In addition, the terminal device may also send other information, such as RV, etc. to the network device, and this application does not limit other information.

[0262] It should be understood that in the present application, if the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource, which can also be described as: if the indication information includes an ACK indication of the first HARQ process, the terminal device does not transmit the data on the second resource according to the third transmission mechanism.

[0263] It should be noted that, assuming that the first resource is an NRU CG and the second resource is an URLLC CG, the terminal device can process the data transmission on the second resource according to the third transmission mechanism and / or on the URLLC CG resource according to the indication information. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information and the data transmission mode on the third resource before receiving the indication information.

[0264] In summary, in the present application, if the first HARQ process corresponds to the second resource, the terminal device processes the data transmission on the second resource according to the third transmission mechanism according to the indication information. If the first HARQ process corresponds to the second resource and the first resource, the terminal device processes or does not process the data transmission on the second resource according to the indication information according to the data transmission mode on the third resource before receiving the indication information. Therefore, the indication information can be applied not only to the first resource, but also to the second resource, thereby expanding the scope of use of the indication information and introducing a non-adaptive data transmission indication mode for the second resource to a certain extent.

The indication information is an ACK / NACK indication for at least one HARQ process, where the HARQ process is a HARQ process corresponding to the first resource, or a HARQ process shared by the first resource and the second resource, wherein the first resource and the second resource are configured differently.

[0268] Step S320: the terminal device processes or does not process the data transmission on the second resource according to the indication information, and / or the terminal device processes the data transmission on the first resource according to the indication information.

The indication information in Embodiment 1 is an ACK / NACK indication for at least one HARQ process, and the HARQ process is a HARQ process corresponding to the first resource and / or the second resource, wherein the configuration modes of the first resource and the second resource are different. The rest of the contents are the same, therefore, Embodiment 6 may refer to the contents of Embodiment 1, and this application will not repeat them.

[0270] For the description of the terminal device processing the data transmission on the first resource according to the indication information in step S320, please refer to Example 2.
