[0039] After introducing the implementation environment involved in the embodiments of the present application, the method for determining the environmental status provided in the embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0040] Please refer to Figure 2 ,Should Figure 2 is a flow chart of a method for determining an environmental state according to an exemplary embodiment. The method can be applied to the above Figure 1 In the implementation environment shown, the method is mainly executed by a terminal device, and may include but is not limited to part or all of the following contents:

[0041] Step 201: Receive an indication message sent by a network device, where the indication message is information related to the interference environment of an unlicensed frequency band covered by the network device.

[0042] Since the unlicensed frequency band is usually subject to interference from other systems, the interference to the unlicensed frequency band is referred to as interference environment.

[0043] Before conducting IIoT communication based on an unlicensed frequency band, it is necessary to determine the interference situation of the unlicensed frequency band. To this end, the network device determines an indication message related to the interference environment of the unlicensed frequency band it covers and sends the indication message to the terminal device. Correspondingly, the terminal device receives the indication message.

[0044] As an example, the indication message is carried in a system message. When the indication message is carried in a system message, the network device sends the indication message to the terminal device by broadcasting, so that the terminal devices in the cell covered by the network device can receive the indication message.

[0045] As another example, the indication message is carried in a specified configuration message. When the indication message is carried in a specified configuration message, the network device sends the indication message to one or part of the terminal devices. Optionally, the specified configuration message can be set by the network device according to actual needs, for example, the specified configuration message can be a specified reconfiguration message, that is, the indication message can be carried in a specified reconfiguration message.

[0046] Step 202: Based on the indication message, determine the interference state of the interference environment.

[0047] Since the indication message is related to the interference environment, the terminal device can determine the interference state of the interference environment based on the indication information. For example, the interference state may include controllable interference or uncontrollable interference, where controllable interference may mean not being seriously interfered with, and uncontrollable interference may mean being seriously interfered with. In this way, the terminal device can determine whether the unlicensed frequency band can be used to transmit IIoT services according to the interference state of the interference environment.

[0048] Optionally, if there is a response indication configured for the network device, respond to the indication message, where the response indication is used to indicate that responding to the indication message is allowed.

[0049] Optionally, if the response indication configured by the network device does not exist, responding to the indication message is prohibited.

[0050] The response indication may be pre-configured by the network device to the terminal device. For example, the network device may select some terminal devices and configure the response indication for these terminal devices. Thus, for these terminal devices configured with the response indication, if they receive the indication message sent by the network device, they may respond to the indication message. For terminal devices not configured with the response indication, even if they receive the indication message, they may ignore the indication message, that is, not respond to the indication message.

[0051] Optionally, the terminal device that is not configured with the response indication is a terminal device requesting an eMBB (Enhanced Mobile Broadband) type service.

[0052] That is, for terminal devices requesting eMBB type services, the network device may not configure a response indication for it. In this way, even if this type of terminal device receives an indication message, it does not respond to the indication message, but still needs to perform regular channel listening and other operations.

[0053] Optionally, if the interference level of the interference environment is lower than a first threshold, data transmission is performed through the designated channel based on the access parameters of the designated channel; or, if the interference level of the interference environment is lower than the first threshold, data transmission is performed through network resources of the unlicensed frequency band.

[0054] Among them, the first threshold can be set according to actual needs. For example, the first threshold can be configured by the network device, or can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0055] Among them, the designated channel can be set according to actual needs. For example, the designated channel can be configured by a network device, or the designated channel can also be determined by the terminal device itself. The embodiments of the present application do not limit this.

[0056] Exemplarily, if the interference level of the interference environment is lower than a first threshold, the interference environment can be considered to be interference controllable. In this case, the terminal device can adopt the access parameters of the designated channel and transmit data through the designated channel, thereby meeting the QoS (Quality of Service) requirements of some services, such as meeting the QoS requirements of URLLC (Ultra-Reliable And Low Latency Communications) services.

[0057] Exemplarily, if the interference level of the interference environment is lower than a first threshold, that is, the interference environment is interference controllable, the terminal device can use the network resources of the unlicensed frequency band for data transmission without adopting any channel access, thereby meeting the QoS requirements of some services such as URLLC.

[0058] Optionally, if the interference level of the interference environment is higher than a second threshold, a specified notification message is reported to the network device based on the reporting configuration information, where the specified notification message is used to indicate a service type that cannot meet the transmission requirement.

[0059] Among them, the second threshold can be set according to actual needs. For example, the second threshold can be configured by the network device, or the second threshold can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0060] In addition, the second threshold may be the same as the first threshold, or the second threshold may be different from the first threshold. When the second threshold is different from the first threshold, the second threshold is usually greater than the first threshold.

[0061] Exemplarily, the reporting configuration information may include but is not limited to at least one of a reporting indication, a reporting method, and a reporting type. The reporting indication is used to indicate whether reporting is required, the reporting method is used to indicate which method to use for reporting, and the reporting type can be used to indicate which types of information need to be reported.

[0062] If the interference level of the interference environment is higher than the second threshold, the interference environment can be considered to be severely interfered, and it can be determined that the interference environment is uncontrollable. In this case, the terminal device can report a specified notification message to the network device based on the reported configuration information to notify the network device which service types cannot meet the QoS requirements.

[0063] As an example, the designated notification message includes a first service type, and the first service type includes a service type of a URLLC service.

[0064] Furthermore, at least two sets of parameter configuration information configured for the network device are obtained, each set of parameter configuration information in the at least two sets of parameter configuration information corresponds to at least one interference state, and parameter configuration information for data transmission is determined based on the at least two sets of parameter configuration information and the interference state of the interference environment.

[0065] That is, the network device can indicate the parameters used by the terminal device for transmitting data under different interference states. To this end, the network device can send at least two sets of parameter configuration information to the terminal device, and each set of parameter configuration information can correspond to at least one interference state. Optionally, the network device can send the at least two sets of parameter configuration information to the terminal device in advance through high-level signaling, for example, through RRC signaling. Optionally, after receiving the at least two sets of parameter configuration information, the terminal device can store them locally.

[0066] In this way, after determining the interference state of the interference environment, the terminal device can determine a corresponding set of parameter configuration information from at least two sets of parameter configuration information pre-configured by the network device according to the interference state, thereby performing data transmission based on the determined parameter configuration information.

[0067] As an example, each group of parameter configuration information includes at least one of the following corresponding relationships (1)-(6):

[0068] (1) A correspondence between an interference level and data compression indication information, where the data compression indication information is used to indicate a corresponding compression algorithm, or the data compression indication information is used to indicate whether there is a corresponding compression algorithm.

[0069] Optionally, the data compression indication information may include a first indication or a second indication, the first indication is used to indicate a compression algorithm based on feedback, and the second indication is used to indicate a compression algorithm not based on feedback.

[0070] Optionally, when the interference level is lower than a first threshold, the correspondence between the interference level and the data compression indication information includes the correspondence between the interference level and the first indication; when the interference level is higher than a second threshold, the correspondence between the interference level and the data compression indication information includes the correspondence between the interference level and the second indication.

[0071] That is, if the interference level is low, a compression algorithm based on feedback may be used, and if the interference level is high, a compression algorithm not based on feedback may be used.

[0072] Optionally, the data compression indication information may include a third indication or a fourth indication, the third indication is used to indicate the use of a compression algorithm, and the fourth indication is used to indicate not to use a compression algorithm.

[0073] Optionally, when the interference level is higher than the second threshold, the correspondence between the interference level and the data compression indication information includes the correspondence between the interference level and the third indication; when the interference level is lower than the first threshold, the correspondence between the interference level and the data compression indication information includes the correspondence between the interference level and the fourth indication.

[0074] That is, if the interference level is high, a compression algorithm may be used to compress the data, and when the interference level is low, no compression algorithm may be used for the data.

[0075] Optionally, the data compression algorithm may include an HC (Header Compression) algorithm. Exemplarily, the HC algorithm may include an EHC (Ethernet Header Compression) algorithm and / or a ROHC (Robust Header Compression) algorithm.

[0076] (2) Correspondence between interference level and bearer transmission status.

[0077] Optionally, the bearer transmission status may include suspending at least one bearer or not suspending at least one bearer, wherein not suspending at least one bearer may also be understood as continuing to transmit at least one bearer.

[0078] Optionally, when the interference level is lower than the first threshold, the correspondence between the interference level and the bearer transmission state may include: a correspondence between the interference level and the bearer transmission state of not suspending at least one bearer. When the interference level is higher than the second threshold, the correspondence between the interference level and the bearer transmission state may include: a correspondence between the interference level and the bearer transmission state of suspending at least one bearer. That is, if the interference level of the interference environment is low, at least one bearer may not be suspended, or at least one bearer may continue to be transmitted; but if the interference level of the interference environment is high, at least one bearer may be suspended.

[0079] Optionally, when suspending at least one bearer, the terminal device may select which bearer or bearers to suspend according to actual needs, or the network device may instruct the terminal device to suspend which bearer or bearers.

[0080] (3) The correspondence between interference level and PBR (Prioritized Bit Rate).

[0081] Optionally, when the interference level is higher than the second threshold, the corresponding relationship between the interference level and the PBR may include: a corresponding relationship between the interference level and a first PBR value. When the interference level is lower than the first threshold, the corresponding relationship between the interference level and the PBR may include: a corresponding relationship between the interference level and a second PBR value, wherein the first PBR value is lower than the second PBR value. That is, if the interference level is higher, a lower PBR value may be used, and if the interference level is lower, a higher PBR value may be used.

[0082] (4) The correspondence between the interference level and BSD (Bucket Size Duration).

[0083] Optionally, when the interference level is higher than the second threshold, the correspondence between the interference level and the BSD may include: a correspondence between the interference level and a first BSD value. When the interference level is lower than the first threshold, the correspondence between the interference level and the BSD may include: a correspondence between the interference level and a second BSD value, wherein the first BSD value is less than the second BSD value. That is, if the interference level is higher, a smaller BSD value may be used, and if the interference level is lower, a larger BSD value may be used.

[0084] (5) The correspondence between interference level and unlicensed frequency band parameters.

[0085] As an example, the unlicensed band parameters may include channel access parameters.

[0086] Optionally, the unlicensed band parameters may include an FBE (Frame Based Equipment) channel access method or an LBE (Load Based Equipment) channel access method. For example, when the interference level is higher than the second threshold, the correspondence between the interference level and the unlicensed band parameters includes: the correspondence between the interference level and the FBE channel access method. When the interference level is lower than the first threshold, the correspondence between the interference level and the unlicensed band parameters includes: the correspondence between the interference level and the LBE channel access method. That is, if the interference level is high, the FBE channel access method can be used, and if the interference level is low, the LBE channel access method can be used.

[0087] Optionally, the unlicensed spectrum parameter may include a first parameter value or a second parameter value of a channel access method. For example, when the interference level is higher than the second threshold, the correspondence between the interference level and the unlicensed frequency band parameter includes: a correspondence between the interference level and the first parameter value of the channel access method. When the interference level is lower than the first threshold, the correspondence between the interference level and the unlicensed frequency band parameter includes: a correspondence between the interference level and the second parameter value of the channel access method. Among them, the channel access method may include an FBE channel access method and / or an LBE channel access method. That is, if the interference level is high, the first parameter value may be used when adopting the FBE channel access method and / or the LBR channel access method, and if the interference level is low, the second parameter value may be used when adopting the FBE channel access method and / or the LBR channel access method.

[0088] (6) Correspondence between interference level and data conflict configuration parameters.

[0089] Among them, the data conflict configuration parameter may include a priority.

[0090] Exemplarily, when the interference level is higher than the second threshold, the correspondence between the interference level and the data conflict configuration parameter may include: a correspondence between the interference level and the first priority. When the interference level is lower than the first threshold, the correspondence between the interference level and the data conflict configuration parameter may include: a correspondence between the interference level and the second priority. That is, if the interference level is high, the first priority may be configured for at least one bearer, and if the interference level is low, the second priority may be configured for at least one bearer.

[0091] In this way, the terminal device can determine which set of parameter configuration information to use for data transmission according to the interference state of the interference environment, or in other words, the terminal device can determine which set of parameter configuration information to use for data transmission according to the interference level of the interference environment.

[0092] In an embodiment of the present application, the network device sends an indication message related to the interference environment of the unlicensed spectrum it covers to the terminal device. In this way, the terminal device can determine the interference status of the interference environment based on the indication message, so as to determine whether IIoT communication can be performed in the unlicensed frequency band.

[0093] Depending on the different contents included in the indication message, the specific implementation process of the embodiments of the present application is different, and will be described in detail through the following embodiments.

[0094] Please refer to Figure 3 ,Should Figure 3 is a flow chart of a method for determining an environmental state according to an exemplary embodiment. The method can be applied to the above Figure 1 In the implementation environment shown, the method is executed by a terminal device and may include the following implementation steps:

[0095] Step 301: receiving an indication message sent by a network device, the indication message including an interference level, the interference level including one of at least two levels, and different levels of the at least two levels corresponding to different interference degrees.

[0096] That is, the interference level of the interference environment can be determined by the network device, and then the determined interference level is indicated to the terminal device through an indication message. The interference level includes one of at least two levels, and the number of levels in the at least two levels can be set according to actual needs.

[0097] Optionally, the at least two levels include a first level and a second level, the first level is used to indicate that the interference level of the interference environment is lower than a first threshold, and the second level is used to indicate that the interference level of the interference environment is higher than a second threshold, and the second threshold is greater than or equal to the first threshold.

[0098] That is, the at least two levels are binary, including the first level and the second level. When the interference level of the interference environment is the first level, it can be considered that the interference level of the interference environment is controllable, and when the interference level of the interference environment is the second level, it can be considered that the interference level of the interference environment is uncontrollable.

[0099] It should be noted that the at least two levels are binary, and in another embodiment, the at least two levels may also include multiple levels, for example, the at least two levels include a first level, a second level, and a third level, wherein the first level is less than the second level, and the second level is less than the third level, that is, the interference level of the interference environment may be divided into three levels: high, medium, and low. Of course, in another embodiment, the at least two levels may also include more multiple levels, and the embodiment of the present application does not limit this.

[0100] In addition, it should be noted that, in some embodiments, the interference level of the interference environment may be divided according to the interference intensity, that is, the interference level may be used to indicate the interference intensity associated with the interference environment.

[0101] Optionally, the indication message also includes an object identifier, which is associated with the interference level. Exemplarily, the object identifier may include at least one of a carrier identifier, a frequency band identifier, a PLMN (Public Land Mobile Network) identifier, a CAG (Closed Access Group) identifier, and a geographic area identifier.

[0102] The carrier identifier may be used to indicate a carrier or a group of carriers, the frequency band identifier may be used to indicate a frequency band, the PLMN identifier may be used to indicate a PLMN, the CAG identifier may be used to indicate a CAG, and the geographic area identifier may be used to indicate a geographic area.

[0103] For example, taking the object identifier including a carrier as an example, the network device can instruct the terminal device which carrier the interference level is specifically for, and associate the interference level with the carrier identifier, and then send the associated interference level and carrier identifier to the terminal device.

[0104] Step 302: Based on the indication message, determine the interference state of the interference environment.

[0105] Since the indication message includes the interference level, the interference state of the interference environment can be determined directly based on the interference level.

[0106] Optionally, if there is a response indication configured for the network device, respond to the indication message, where the response indication is used to indicate that responding to the indication message is allowed.

[0107] Optionally, if the response indication configured by the network device does not exist, responding to the indication message is prohibited.

[0108] The response indication may be pre-configured by the network device to the terminal device. For example, the network device may select some terminal devices and configure the response indication for these terminal devices. Thus, for these terminal devices configured with the response indication, if they receive the indication message sent by the network device, they may respond to the indication message. For terminal devices not configured with the response indication, even if they receive the indication message, they may ignore the indication message, that is, not respond to the indication message.

[0109] Optionally, the terminal device that is not configured with the response indication is a terminal device requesting eMBB type services.

[0110] That is, for terminal devices requesting eMBB type services, the network device may not configure a response indication for it. In this way, even if this type of terminal device receives an indication message, it does not respond to the indication message, but still needs to perform regular channel listening and other operations.

[0111] Optionally, if the interference level of the interference environment is lower than a first threshold, data transmission is performed through the designated channel based on the access parameters of the designated channel; or, if the interference level of the interference environment is lower than the first threshold, data transmission is performed through network resources of the unlicensed frequency band.

[0112] Among them, the first threshold can be set according to actual needs. For example, the first threshold can be configured by the network device, or can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0113] Among them, the designated channel can be set according to actual needs. For example, the designated channel can be configured by a network device, or the designated channel can also be determined by the terminal device itself. The embodiments of the present application do not limit this.

[0114] Exemplarily, if the interference level of the interference environment is lower than a first threshold, the interference environment can be considered to be interference controllable. In this case, the terminal device can adopt the access parameters of the designated channel and transmit data through the designated channel, thereby meeting the QoS (Quality of Service) requirements of some services, such as meeting the QoS requirements of URLLC (Ultra-Reliable And Low Latency Communications) services.

[0115] Exemplarily, if the interference level of the interference environment is lower than a first threshold, that is, the interference environment is interference controllable, the terminal device can use the network resources of the unlicensed frequency band for data transmission without adopting any channel access, thereby meeting the QoS requirements of some services such as URLLC.

[0116] Optionally, if the interference level of the interference environment is higher than a second threshold, a specified notification message is reported to the network device based on the reporting configuration information, where the specified notification message is used to indicate a service type that cannot meet the transmission requirement.

[0117] Among them, the second threshold can be set according to actual needs. For example, the second threshold can be configured by the network device, or the second threshold can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0118] In addition, the second threshold may be the same as the first threshold, or the second threshold may be different from the first threshold. When the second threshold is different from the first threshold, the second threshold is usually greater than the first threshold.

[0119] Exemplarily, the reporting configuration information may include but is not limited to at least one of a reporting indication, a reporting method, and a reporting type. The reporting indication is used to indicate whether reporting is required, the reporting method is used to indicate which method to use for reporting, and the reporting type can be used to indicate which types of information need to be reported.

[0120] If the interference level of the interference environment is higher than the second threshold, the interference environment can be considered to be severely interfered, and it can be determined that the interference environment is uncontrollable. In this case, the terminal device can report a specified notification message to the network device based on the reported configuration information to notify the network device which service types cannot meet the QoS requirements.

[0121] As an example, the designated notification message includes a first service type, and the first service type includes a service type of a URLLC service.

[0122] Step 303: Determine parameter configuration information for data transmission according to the interference state.

[0123] The specific implementation can be found in the above Figure 2 The relevant contents in the illustrated embodiment will not be repeated here.

[0124] In an embodiment of the present application, the network device sends an indication message related to the interference environment of the unlicensed spectrum it covers to the terminal device. In this way, the terminal device can determine the interference status of the interference environment based on the indication message, so as to determine whether IIoT communication can be performed in the unlicensed frequency band.

[0125] Please refer to Figure 4 ,Should Figure 4 is a flow chart of a method for determining an environmental state according to an exemplary embodiment. The method can be applied to the above Figure 1 In the implementation environment shown, the method is executed by a terminal device and may include but is not limited to part or all of the following contents:

[0126] Step 401: Receive indication information sent by a network device, the indication information including at least one of a judgment condition, a judgment strategy and a level quantity, wherein the judgment condition includes a measurement parameter related to the channel quality, the judgment strategy is used to indicate how to determine a judgment result based on the judgment condition, and the level quantity refers to the type of interference level included in the judgment result.

[0127] Optionally, the judgment condition may include at least one of the measurement parameters related to channel quality, such as RSSI (Received Signal Strength Indication), RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), LBT (Listen Before Talk) times, CO (Channel Occupancy), etc.

[0128] Optionally, the judgment strategy may include: how to determine the interference level when the judgment condition is higher than a first threshold, or how to determine the interference level when the judgment condition is lower than a second threshold. The first threshold and the second threshold may be set according to actual needs, for example, the first threshold and the second threshold may be set by default by the network device, and the first threshold and the second threshold may be the same or different, which is not limited in the embodiments of the present application.

[0129] Optionally, the number of levels may be used to indicate how many types of interference levels there are. For example, the number of levels may be 2, or the number of levels may be an integer greater than 2.

[0130] That is, in this embodiment, the network device may indicate the method information for determining the interference environment to the terminal device.

[0131] It should be noted that when the indication message includes one of the above-mentioned judgment conditions, judgment strategies and level numbers, the terminal device can combine other methods to make judgments. For example, when the indication message includes a judgment condition, the terminal device can use a default or pre-defined judgment strategy to determine the interference status of the interference environment based on the judgment condition.

[0132] Step 402: Based on the indication message, determine the interference state of the interference environment.

[0133] Exemplarily, when the indication message includes a judgment condition and a judgment strategy, measurements can be performed according to the judgment condition to obtain measurement results, and then based on the measurement results and the judgment strategy, the interference level of the interference environment is determined, thereby determining the interference state of the interference environment.

[0134] Optionally, the specific implementation of determining the interference state of the interference environment based on the indication message may further include: determining the interference state of the interference environment according to the indication message and the resources to be measured.

[0135] That is, the terminal device can determine the interference state of the interference environment based on the method information for determining the interference environment configured by the network device, combined with its own relevant information. Exemplarily, it is assumed that the above-mentioned indication message includes a judgment condition and a judgment strategy, the judgment condition includes RSRP, and the judgment strategy includes when the judgment condition is greater than the first threshold, determining the interference level to be the first level, and when the judgment condition is less than the second threshold, determining the interference level to be the second level. In this way, the terminal device can measure the RSRP of the resource to be measured. If the measured value of the RSRP is greater than the first threshold, it can be determined that the interference level of the interference environment is the first level, thereby determining the interference state of the interference environment.

[0136] Optionally, the resource to be measured includes at least one of a carrier, a frequency band, a PLMN, a CAG, and a geographical area.

[0137] That is, when measuring the resources to be measured, at least one of the carrier, frequency band, PLMN, CAG and geographical area may be measured. For example, if the judgment condition includes RSRQ and the resources to be measured include PLMN, the terminal device may measure the RSRQ of the PLMN.

[0138] Furthermore, indication information of the interference state of the interference environment is reported to the network device.

[0139] Since the interference state of the interference environment is determined by the terminal device, in order to facilitate the network device to also know the interference state of the interference environment, the terminal device sends the indication information of the interference state to the network device after determining the interference state. Exemplarily, the indication information may include the interference level.

[0140] Optionally, the implementation of reporting the indication information of the interference state of the interference environment to the network device may include any one of the following implementation methods:

[0141] The first implementation method is to report the interference status indication information of the interference environment to the network device at specified time intervals.

[0142] The designated duration may be set according to actual needs. For example, the designated duration may be set by default by the terminal device, or may be configured for the terminal device by the network device.

[0143] That is, the terminal device may periodically report indication information of the interference status of the interference environment to the network device.

[0144] The second implementation manner: when an event triggering condition is detected, the indication information of the interference state of the interference environment is reported to the network device.

[0145] The event triggering condition may be set according to actual needs, for example, may be set by default by the terminal device, or may be configured for the terminal device by the network device. Exemplarily, when the interference environment changes, the terminal device determines that the event triggering condition is detected.

[0146] A third implementation manner: when a trigger signaling sent by a network device is received, indication information of the interference state of the interference environment is reported to the network device.

[0147] That is, the terminal device may not actively report the indication information of the determined interference status, but when receiving the trigger signaling sent by the network device, it determines that the network device needs to know the interference status of the interference environment. At this time, the terminal device then reports the indication information of the determined interference status to the network device.

[0148] The indication information also includes an object identifier associated with the interference state, wherein the object identifier includes at least one of a carrier identifier, a frequency band identifier, a PLMN identifier, a CAG identifier, and an identifier of a geographical area.

[0149] Since the interference status of the determined interference environment may be for at least one of the carrier, frequency band, PLMN, CAG and geographical area, in order to facilitate the network device to know in detail which resource or resources the interference status of the interference environment is for, the terminal device reports the object identifier associated with the interference status to the network device.

[0150] Optionally, if there is a response indication configured for the network device, respond to the indication message, where the response indication is used to indicate that responding to the indication message is allowed.

[0151] Optionally, if the response indication configured by the network device does not exist, responding to the indication message is prohibited.

[0152] The response indication may be pre-configured by the network device to the terminal device. For example, the network device may select some terminal devices and configure the response indication for these terminal devices. Thus, for these terminal devices configured with the response indication, if they receive the indication message sent by the network device, they may respond to the indication message. For terminal devices not configured with the response indication, even if they receive the indication message, they may ignore the indication message, that is, not respond to the indication message.

[0153] Optionally, the terminal device that is not configured with the response indication is a terminal device requesting eMBB type services.

[0154] That is, for terminal devices requesting eMBB type services, the network device may not configure a response indication for it. In this way, even if this type of terminal device receives an indication message, it does not respond to the indication message, but still needs to perform regular channel listening and other operations.

[0155] Optionally, if the interference level of the interference environment is lower than a first threshold, data transmission is performed through the designated channel based on the access parameters of the designated channel; or, if the interference level of the interference environment is lower than the first threshold, data transmission is performed through network resources of the unlicensed frequency band.

[0156] Among them, the first threshold can be set according to actual needs. For example, the first threshold can be configured by the network device, or can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0157] Among them, the designated channel can be set according to actual needs. For example, the designated channel can be configured by a network device, or the designated channel can also be determined by the terminal device itself. The embodiments of the present application do not limit this.

[0158] Exemplarily, if the interference level of the interference environment is lower than a first threshold, the interference environment can be considered to be interference controllable. In this case, the terminal device can adopt the access parameters of the designated channel and transmit data through the designated channel, thereby meeting the QoS (Quality of Service) requirements of some services, such as meeting the QoS requirements of URLLC (Ultra-Reliable And Low Latency Communications) services.

[0159] Exemplarily, if the interference level of the interference environment is lower than a first threshold, that is, the interference environment is interference controllable, the terminal device can use the network resources of the unlicensed frequency band for data transmission without adopting any channel access, thereby meeting the QoS requirements of some services such as URLLC.

[0160] Optionally, if the interference level of the interference environment is higher than a second threshold, a specified notification message is reported to the network device based on the reporting configuration information, where the specified notification message is used to indicate a service type that cannot meet the transmission requirement.

[0161] Among them, the second threshold can be set according to actual needs. For example, the second threshold can be configured by the network device, or the second threshold can also be set by default by the terminal device. The embodiment of the present application does not limit this.

[0162] In addition, the second threshold may be the same as the first threshold, or the second threshold may be different from the first threshold. When the second threshold is different from the first threshold, the second threshold is usually greater than the first threshold.

[0163] Exemplarily, the reporting configuration information may include but is not limited to at least one of a reporting indication, a reporting method, and a reporting type. The reporting indication is used to indicate whether reporting is required, the reporting method is used to indicate which method to use for reporting, and the reporting type can be used to indicate which types of information need to be reported.

[0164] If the interference level of the interference environment is higher than the second threshold, the interference environment can be considered to be severely interfered, and it can be determined that the interference environment is uncontrollable. In this case, the terminal device can report a specified notification message to the network device based on the reported configuration information to notify the network device which service types cannot meet the QoS requirements.

[0165] As an example, the designated notification message includes a first service type, and the first service type includes a service type of a URLLC service.

[0166] Step 403: Determine a set of parameter configuration information for data transmission according to the interference state.
