[0115] 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.

[0116] To facilitate a better understanding of the embodiments of the present application, the relevant background of NRU and CG enhancement in NRU are first described below.

[0117] CG enhancement in URLLC:

[0118] (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.

[0119] (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.

[0120] (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. Among them, the use of automatic transmission can be determined by the automatic transmission parameter autonomousTx.

[0121] NRU related background:

[0122] NRU includes the following work scenarios:

[0123] Scenario A: Carrier aggregation scenario, the primary cell (PCell) corresponds to the authorized spectrum, and the secondary cell (SCell) corresponds to the NRU.

[0124] Scenario B: Dual-connection working scenario, PCell corresponds to LTE authorized spectrum, and primary secondary cell (PScell) corresponds to NRU.

[0125] Scenario C: Independent working scenario, an independent cell works on NRU.

[0126] Scenario D: NR single-cell scenario, the uplink (UL) works on the licensed spectrum and the downlink (DL) works on the NRU;

[0127] Scenario E: Dual-connectivity working scenario, PCell corresponds to NR licensed spectrum, and PScell ​​corresponds to NRU.

[0128] 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.

[0129] 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.

[0130] CG enhancements in NRU:

[0131] (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 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.

[0132] (2) NRU introduces multiple CG configurations, where multiple CG configurations can share the HARQ process.

[0133] (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.

[0134] The data transmission on the CG resource can be interrupted by the dynamic scheduling DCI and DFI. The details are shown in Table 1:

[0135] Table 1

[0136]

[0137] As described above, when a CG resource corresponds to multiple available HARQ processes, how to select one HARQ process from the multiple HARQ processes and perform data transmission is a technical problem that needs to be solved urgently in this application.

[0138] In order to solve the above technical problem, the present application proposes that a terminal device selects a HARQ process from multiple HARQ processes according to a HARQ process selection rule to perform data transmission.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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 licensed spectrum or unlicensed spectrum.

[0143] 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.

[0144] 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.

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.

[0147] 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.

[0148] 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.

[0149] 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 those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those 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.

The network device can be an access point (AP) in WLAN, a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device or base station (gNB) in the NR network, or a network device in a future evolved PLMN network, or a network device in an NRU, etc.

[0151] 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.

[0175] Optionally, the above data types can be used in combination or separately. For example, the data type for the initial transmission data can be further divided into data types, such as the initial transmission data is URLLC data. Similarly, the data type for the retransmission data can also be further divided into data types.

[0176] Optionally, the above HARQ process selection rule may be a HARQ process selection rule for an initially transmitted data type. It may also be a HARQ process selection rule for a retransmitted data type. It may also be a HARQ process selection rule for any data type, that is, the rule has no restrictions on the data type, for example: the rule is applicable to both initially transmitted data and retransmitted data, and for another example: the rule is applicable to both data of a URCCL service and data of a V2X service.

[0177] Optionally, the HARQ process selection rule for the initial transmission data type, the HARQ process selection rule for the retransmission data type, and the HARQ process selection rule for any data type may be completely the same, or not completely the same. For example: the HARQ process selection rule for the initial transmission data type performs data transmission according to the priority of the HARQ process, the HARQ process selection rule for the retransmission data type performs data transmission according to the priority of the resources corresponding to the HARQ process, and the HARQ process selection rule for any data type performs data transmission according to the process number corresponding to the HARQ process. That is, it indicates that the HARQ process selection rules in the three cases are completely different. For another example: the HARQ process selection rule for the initial transmission data type, the HARQ process selection rule for the retransmission data type, and the HARQ process selection rule for any data type all perform data transmission according to the priority of the HARQ process, that is, it indicates that the HARQ process selection rules in the three cases are completely the same. For another example: the HARQ process selection rule for the initial transmission data type and the retransmission data type all perform data transmission according to the priority of the HARQ process, and the HARQ process selection rule for any data type performs data transmission according to the process number corresponding to the HARQ process. This means that the HARQ process selection rules in the three cases are not exactly the same.

[0178] Optionally, the at least one HARQ process selection rule may be predefined, preconfigured, or indicated by the network.

[0179] Optionally, the data corresponding to the above-mentioned multiple HARQ processes may all be retransmission data, or all be initial transmission data, or part of the data may be retransmission data and part of the data may be initial transmission data.

[0180] It should be understood that if the data corresponding to the above-mentioned multiple HARQ processes are retransmission data, correspondingly, the above-mentioned HARQ process selection rule may be a HARQ process selection rule for the retransmission data type, or a HARQ process selection rule for any data type. If the data corresponding to the above-mentioned multiple HARQ processes are initial transmission data, correspondingly, the above-mentioned HARQ process selection rule may be a HARQ process selection rule for the initial transmission data type, or a HARQ process selection rule for any data type. If the data corresponding to the above-mentioned multiple HARQ processes are part of the initial transmission data and part of the retransmission data, correspondingly, the above-mentioned HARQ process selection rule may be a HARQ process selection rule for the initial transmission data type or the retransmission data type. Based on this, the terminal device needs to combine the HARQ process selection rule and other HARQ process selection rules to select a first HARQ process from multiple HARQ processes. The HARQ process selection rule here is, for example, a rule of transmitting retransmission data first and then transmitting initial transmission data. If the data corresponding to the above-mentioned multiple HARQ processes are part of the initially transmitted data and part of the retransmitted data, correspondingly, the above-mentioned HARQ process selection rule may also be a HARQ process selection rule for any data type.

[0181] It should be understood that the initially transmitted data in this application is also described as newly transmitted data, and this application does not impose any limitation on this.

[0182] Optionally, the terminal device obtains at least one of the following information, but is not limited to:

[0183] 1. Priority of multiple HARQ processes.

[0184] 2. The priority of resources corresponding to multiple HARQ processes.

[0185] 3. The priority of LCH in the MAC PDU corresponding to multiple HARQ processes.

[0186] 4. QoS requirements for data corresponding to multiple HARQ processes.

[0187] 5. Data types corresponding to multiple HARQ processes.

[0188] 6. HARQ process numbers corresponding to multiple HARQ processes.

[0189] Optionally, at least one of the above information is carried in the configuration information of the CG resource or in other information, and this application does not impose any restrictions on this.

[0190] The following is an exemplary description of selecting a HARQ process in conjunction with the HARQ process selection rule:

[0191] Example 1: If the HARQ process selection rule is a rule for selecting according to the priority of the HARQ process, and the priorities of the above-mentioned multiple HARQ processes are different, the terminal device preferentially selects the HARQ process with the highest HARQ process priority for transmission.

[0192] Example 2: If the HARQ process selection rule is based on the resource selection rule corresponding to the HARQ process, and the resource priorities corresponding to multiple HARQ processes are different, the terminal device will give priority to the HARQ process with the highest resource priority for transmission. For example: The CG resources corresponding to HARQ process 1 include: CG resource 1 and CG resource 2, and the CG resource corresponding to HARQ process 2 is CG resource 1, and the priority of CG resource 1 is lower than the priority of CG resource 2. In this case, the terminal device transmits the data of HARQ process 1 through CG resource 1 first.

[0193] Example 3: If the HARQ process selection rule is based on the LCH selection rule in the MAC PDU corresponding to the HARQ process, and the priorities of the LCHs in the MAC PDUs corresponding to multiple HARQ processes are different, the terminal device will prioritize the HARQ process with the highest LCH for transmission.

[0194] Example 4: If the HARQ process selection rule is a rule for selecting resources corresponding to the HARQ process, and the rule is a rule for retransmitted data, then if the resource priorities corresponding to multiple HARQ processes are different, and the data corresponding to multiple HARQ processes are all retransmitted data, the terminal device prioritizes the HARQ process with the highest resource priority for data transmission.

[0195] Example 5: If the HARQ process selection rule is a rule for selecting according to the data type corresponding to the HARQ process, and the data corresponding to multiple HARQ processes include retransmission data and initial transmission data, the terminal device gives priority to the HARQ process corresponding to the initial transmission data.

[0196] Example 6: If the HARQ process selection rule is a rule for selecting according to the data type corresponding to the HARQ process, and the data corresponding to multiple HARQ processes include retransmission data and initial transmission data, and the initial transmission data is data corresponding to the URLLC service, the UE gives priority to the HARQ process corresponding to the initial transmission data.

[0197] Example 7: If the HARQ process selection rule is a rule for selecting according to the lifetime of the data corresponding to the HARQ process, and the data corresponding to multiple HARQ processes include retransmission data and initial transmission data, the initial transmission data has a lifetime, while the retransmission data has no lifetime, then the terminal device gives priority to the HARQ process corresponding to the initial transmission data for transmission.

[0198] Example 8: If the HARQ process selection rule is a rule selected according to the lifetime of the data corresponding to the HARQ process, and the data corresponding to multiple HARQ processes are retransmitted data, the terminal device selects the HARQ process corresponding to the retransmitted data that first does not meet the lifetime for transmission.

[0199] In summary, in the present application, the terminal device can select a first HARQ process from multiple HARQ processes according to the HARQ process selection rule, and transmit the data on the first HARQ process through the CG resource, that is, transmit the data corresponding to the first HARQ process through the CG resource. Further, the HARQ process selection rule may include at least one of the following: selection according to the priority of the HARQ process, selection according to the priority of the resources corresponding to the HARQ process, selection according to the priority of the LCH in the MAC PDU corresponding to the HARQ process, selection according to the QoS requirement of the data corresponding to the HARQ process, selection according to the data type corresponding to the HARQ process, and selection according to the HARQ process number. In this way, data with a high priority corresponding to the HARQ process, or data with a high priority corresponding to the resource, or data with a high priority corresponding to the LCH, or data with a high QoS requirement can be transmitted preferentially, or retransmission data can be transmitted preferentially, or data corresponding to the HARQ process number preconfigured or predefined by the network device can be transmitted preferentially, so as to ensure the timely transmission of these data.

[0200] Optionally, when the first condition is met, the terminal device selects a first HARQ process from multiple HARQ processes according to a HARQ process selection rule.

[0201] Optionally, the first condition includes at least one of the following:

[0202] 1. The terminal device receives the first indication information.

[0203] 2. The terminal device is R17 or later version.

[0204] 3. Terminal equipment is a terminal equipment that supports specific services.

[0205] 4. The terminal device accesses specific services on the NRU.

[0206] 5. The terminal device has the ability to select the HARQ process according to the HARQ process selection rule.

[0207] The first indication information is used to indicate that the HARQ process is selected according to the HARQ process selection rule.

[0208] Optionally, if the network device determines that the terminal device has the ability to select the HARQ process according to the HARQ process selection rule, or the network device determines that the terminal device supports selecting the HARQ process according to the HARQ process selection rule, the network device sends the first indication information to the terminal device. That is, only when the network device determines that the terminal device has the ability to select the HARQ process according to the HARQ process selection rule, or the network device determines that the terminal device supports selecting the HARQ process according to the HARQ process selection rule, the network device is triggered to send the above-mentioned first indication information.

[0209] Optionally, the first indication information is indication information for an initially transmitted data type. Alternatively, the first indication information is indication information for a retransmitted data type. Alternatively, the first indication information is indication information for any data type. That is, the HARQ process selection rule indicated by the first indication information is indication information for an initially transmitted data type. Alternatively, the HARQ process selection rule indicated by the first indication information is indication information for a retransmitted data type. Alternatively, the HARQ process selection rule indicated by the first indication information is indication information for any data type.

[0210] Optionally, the HARQ process selection rules indicated by the first indication information for the initial transmission data type, the retransmission data type, and any data type are completely the same or not completely the same. For example: the HARQ process selection rule for the initial transmission data type indicated by the first indication information is to transmit data according to the priority of the HARQ process, the HARQ process selection rule for the retransmission data type indicated by the first indication information is to transmit data according to the priority of the resources corresponding to the HARQ process, and the HARQ process selection rule for any data type indicated by the first indication information is to transmit data according to the process number corresponding to the HARQ process. That is, it indicates that the HARQ process selection rules in the three cases are completely different. For another example: the HARQ process selection rule for the initial transmission data type indicated by the first indication information, the HARQ process selection rule for the retransmission data type indicated by the first indication information, and the HARQ process selection rule for any data type indicated by the first indication information are all to transmit data according to the priority of the HARQ process, that is, it indicates that the HARQ process selection rules in the three cases are completely the same. For another example, the HARQ process selection rules for the initial transmission data type and the retransmission data type indicated by the first indication information are all to transmit data according to the priority of the HARQ process, and the HARQ process selection rules for any data type indicated by the first indication information are to transmit data according to the process number corresponding to the HARQ process. This indicates that the HARQ process selection rules in the three cases are not exactly the same.

[0211] Optionally, the first indication information may be one or more. For example, the first indication information is indication information for any data type. In this case, only one first indication information is needed. However, when the data corresponding to the multiple HARQ processes include initial transmission data and retransmission data, and the first indication information is indication information for different types of data separately, in this case, multiple first indication information are needed.

[0212] Optionally, the first indication information is carried in the configuration information of the CG resource or in other information, but is not limited to this.

[0213] It should be understood that the initial transmission data type targeted by the first indication information refers to the initial transmission data type corresponding to the HARQ process, and the retransmission data type targeted by the first indication information refers to the retransmission data type corresponding to the HARQ process.

[0214] Optionally, the network device determines that the terminal device has the ability to select the HARQ process according to the HARQ process selection rule, or determines that the terminal device supports selecting the HARQ process according to the HARQ process selection rule according to at least one of the following, but is not limited to this:

[0215] 1. The terminal device is R17 or later version.

[0216] 2. Terminal equipment is a terminal equipment that supports specific services.

[0217] 3. The terminal device accesses specific services on the NRU.

[0218] 4. The network device receives capability information sent by the terminal device, where the capability information is used to indicate that the terminal device has the capability to select a HARQ process according to the HARQ process selection rule.

[0219] Optionally, the specific service includes at least one of the following, but is not limited thereto: a first service, a service with a specific priority.

[0220] Optionally, the first service includes at least one of the following, but is not limited to: V2X service, time sensitive communication (TSC) service, and URLLC service.

[0221] In summary, in the present application, when the terminal device satisfies the first condition, the terminal device selects the first HARQ process from multiple HARQ processes according to the HARQ process selection rule. Not in all cases, the terminal device selects the first HARQ process from multiple HARQ processes according to the HARQ process selection rule, thereby improving the flexibility of HARQ process selection.

[0222] As mentioned above, in the CG enhancement scheme in NRU, the status of the CG retransmission timer and the HARQ process are introduced to support data transmission or retransmission triggered when the CG resources cannot be transmitted or the transmission fails due to LBT failure. Among them, after the CG retransmission timer times out, if the CG timer has not timed out and no network feedback is received, the data of the corresponding HARQ process on the available CG resources can be transmitted. So when to start or restart the CG timer and / or CG retransmission timer is a technical problem that needs to be solved urgently in this application.

The resources of the terminal device may be CG resources of the terminal device or other resources of the terminal device.

The other resources may be other resources of the terminal device, such as other CG resources, DG resources, PUCCH resources, etc.; when the resources of the terminal device are CG resources, the other resources may be resources of other terminal devices; when the resources of the terminal device are not CG resources, the other resources may be resources of other terminal devices.

[0253] Optionally, in the present application, the CG resource may be replaced by an uplink authorization resource, that is, the uplink authorization resource may be a CG resource or other uplink authorization resource, and the present application does not impose any restrictions on this.

[0254] It should be understood that the priority of the terminal device's resources is lower than or equal to the priority of other resources and is also described as the terminal device's resources being low-priority resources.

[0255] Optionally, when the terminal device uses CG resources, and the reason why the CG resources are low-priority resources includes at least one of the following, but is not limited to: there is a conflict between the CG resources and other resources, the CG resources correspond to a MAC PDU that is not transmitted with priority, the data corresponding to the CG resources are not transmitted, the data corresponding to the CG resources are not transmitted by the physical layer, the data transmission corresponding to the CG resources is canceled, and the transmission of the CG resources is not executed.

[0256] Optionally, the other resources in conflict with the CG resources may be dynamic resources or other resources of the terminal device, or CG resources, dynamic resources, etc. of other terminal devices, and this application does not impose any restrictions on this.

That is, the first time can be the end time of the last time domain symbol of the CG resource, or can be later than the end time of the last time domain symbol of the CG resource.

[0260] Optionally, the method further includes: if the terminal device satisfies any of the following and satisfies the third condition, the terminal device suspends (pending) the HARQ process corresponding to the CG resource and / or determines that the data corresponding to the CG resource is transmitted. Any of the following situations includes: the terminal device is not configured with automatic transmission parameters, the terminal device is not configured with automatic transmission parameters and is configured with resource selection based on LCH priority, and the terminal device uses NRU automatic retransmission.

[0261] Optionally, the method further includes: if the terminal device satisfies any of the following and satisfies the third condition, the terminal device suspends (pending) the HARQ process corresponding to the CG resource and / or determines that the data corresponding to the CG resource has not been transmitted.

The other resources may be other resources of the terminal device, such as dynamic resources or another CG resource or PUCCH resource; when the resource of the terminal device is a CG resource, the other resource may be a resource of other terminal devices; when it is not a CG resource, the other resource may be a resource of other terminal devices.

[0279] In summary, the present application provides a solution for when to start or restart the CG timer and / or the CG retransmission timer, for example: to ensure that the most recent CG resource will not be unavailable because the CG timer is running, thereby causing a delay in the transmission of the low-priority MAC PDU. Another example: to ensure that the URLLC automatic transmission mechanism can operate normally. Therefore, when the CG timer runs, the transmission can be considered to be executed accordingly. Only when the transmission of low-priority resources is considered not to be executed can the URLLC automatic transmission mechanism operate normally.

[0324] In summary, the present application provides a solution for when to stop the CG timer and / or the CG retransmission timer, for example: to ensure that the most recent CG resource will not be unavailable because the CG timer is running, thereby causing a delay in the transmission of the low-priority MAC PDU. Another example: to ensure that the URLLC automatic transmission mechanism can operate normally. Therefore, when the CG timer runs, the transmission can be considered to be executed accordingly. Only when the transmission of low-priority resources is considered not to be executed can the URLLC automatic transmission mechanism operate normally.
