Having described the implementation environment related to the embodiments of the present application, a detailed description will be given of a method for determining an environmental state provided by the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a method for determining an environmental status according to an exemplary embodiment, where the method may be applied to the implementation environment shown in fig. 1 and is mainly performed by a terminal device, and the method may include, but is not limited to, part or all of the following:

step 201, receiving an indication message sent by a network device, wherein the indication message is information related to an interference environment of an unlicensed frequency band covered by the network device.

Among them, since the unlicensed band is generally subject to interference from other systems, the interference to which the unlicensed band is subject is referred to herein as an interference environment.

Before IIoT communication is performed based on the unlicensed band, an interference condition of the unlicensed band needs to be determined, for this purpose, the network device determines an indication message related to an interference environment of the unlicensed band covered by the network device, and sends the indication message to the terminal device, and correspondingly, the terminal device receives the indication message.

As an example, the indication message is carried in a system message. When the indication message is carried in the system message, the network device sends the indication message to the terminal device in a broadcast mode, so that the terminal device in the cell covered by the network device can receive the indication message.

As another example, the indication message is carried in a specified configuration message. When the indication message is carried in the specified configuration message, the network device sends the indication message to one or a part of the terminal devices. Alternatively, the specific configuration message may be set by the network device according to actual requirements, for example, the specific configuration message may be a specific reconfiguration message, i.e. the indication message may be carried in the specific reconfiguration message.

Step 202, determining the interference state of the interference environment based on the indication message.

Since the indication message is related to the interference environment, the terminal device may determine an interference state of the interference environment based on the indication information, and the interference state may include, for example, interference controllable or interference uncontrollable, where interference controllable may mean not severely interfered, and interference uncontrollable may mean severely interfered. Thus, the terminal device can determine whether the unlicensed band can be used for transmitting IIoT services according to the interference state of the interference environment.

Optionally, if there is a response indication configured by the network device, responding to the indication message, where the response indication is used to indicate that the response to the indication message is allowed.

Optionally, if the response indication of the network device configuration does not exist, disabling the response indication message.

Wherein the response indication may be pre-configured to the terminal devices by the network device, the network device may select some terminal devices and configure the response indication for the terminal devices, so that for the terminal devices configured with the response indication, if an indication message sent by the network device is received, the response may be performed in response to the indication message. And for the terminal device not configured with the response instruction, even if the instruction message is received, the instruction message can be ignored, i.e. the instruction message is not responded.

Optionally, the terminal device not configured with the response indication is a terminal device requesting eMBB (Enhanced Mobile Broadband, enhanced mobile bandwidth) type services.

That is, for a terminal device requesting eMBB type services, the network device may not configure a response indication for it, and thus, for this type of terminal device, even when receiving an indication message, it does not respond to the indication message, but still needs to perform operations such as regular channel listening.

Optionally, if the interference degree of the interference environment is lower than a first threshold, performing data transmission through the designated channel based on the access parameter of the designated channel, or if the interference degree of the interference environment is lower than the first threshold, performing data transmission through the network resource of the unlicensed frequency band.

The first threshold may be set according to actual requirements, for example, the first threshold may be configured by a network device, or may be set by default by the terminal device, which is not limited in the embodiment of the present application.

The designated channel may be set according to actual requirements, for example, the designated channel may be configured by a network device, or the designated channel may be determined by a terminal device itself, which is not limited in the embodiment of the present application.

For example, if the interference level of the interference environment is below the first threshold, the interference environment may be considered interference controllable, in which case the terminal device may take access parameters of a designated channel over which to transmit data, thereby meeting QoS (Quality of Service ) requirements of some traffic, such as meeting QoS requirements of URLLC (Ultra-Reliable And Low Latency Communications, high reliability and low latency communication) traffic.

For example, if the interference level of the interference environment is below the first threshold, i.e. the interference environment is interference controllable, the terminal device may not use any channel access to use the network resources of the unlicensed band for data transmission, thereby meeting QoS requirements of some traffic such as URLLC.

Optionally, if the interference degree of the interference environment is higher than the second threshold, reporting a specified notification message 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.

The second threshold may be set according to actual requirements, for example, the second threshold may be configured by a network device, or the second threshold may be set by default by the terminal device, which is not limited in the embodiment of the present application.

The second threshold value may be the same as the first threshold value, or may be different from the first threshold value, and is generally larger than the first threshold value when the second threshold value is different from the first threshold value.

The reporting configuration information may include, but is not limited to, at least one of a reporting instruction, a reporting mode, and a reporting type, where the reporting instruction is used to indicate whether reporting is needed, the reporting mode is used to indicate what mode is used to report, and the reporting type may be used to indicate what types of information need to be reported.

If the interference level of the interference environment is above the second threshold, the interference environment may be considered severely interfered, at which point it may be determined that the interference environment is interference uncontrollable. In this case, the terminal device may report a specified notification message to the network device based on the reporting configuration information, so as to notify the network device which service types of services cannot meet the QoS requirement.

As an example, the specified notification message includes a first service type that includes a service type of URLLC services.

Further, at least two sets of parameter configuration information configured by 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 according to the at least two sets of parameter configuration information and the interference state of the interference environment.

That is, the network device may instruct the terminal device to use parameters for transmitting data in different interference states, and for this purpose, the network device may issue at least two sets of parameter configuration information to the terminal device, where each set of parameter configuration information may correspond to at least one interference state. Alternatively, the network device may issue the at least two sets of parameter configuration information to the terminal device through higher layer signaling in advance, for example, the network device may issue the parameter configuration information through RRC signaling. Optionally, after receiving the at least two sets of parameter configuration information, the terminal device may store the parameter configuration information locally.

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 preconfigured by the network device according to the interference state, so as to perform data transmission based on the determined parameter configuration information.

As an example, the each set of parameter configuration information includes at least one of the following (1) - (6) correspondence relations:

(1) The interference level and the data compression indication information are used for indicating the corresponding compression algorithm or the data compression indication information is used for indicating whether the compression algorithm corresponds or not.

Alternatively, the data compression indication information may include a first indication for indicating a compression algorithm based on feedback or a second indication for indicating a compression algorithm not based on feedback.

Optionally, when the interference level is lower than a first threshold, the corresponding relation between the interference level and the data compression indication information comprises a corresponding relation between the interference level and the first indication, and when the interference level is higher than a second threshold, the corresponding relation between the interference level and the data compression indication information comprises a corresponding relation between the interference level and the second indication.

That is, if the interference level is low, a feedback-based compression algorithm may be employed, and if the interference level is high, a non-feedback-based compression algorithm may be employed.

Alternatively, the data compression indication information may include a third indication for indicating that the compression algorithm is adopted or a fourth indication for indicating that the compression algorithm is not adopted.

Optionally, when the interference level is higher than the second threshold, the corresponding relation between the interference level and the data compression indication information comprises a corresponding relation between the interference level and the third indication, and when the interference level is lower than the first threshold, the corresponding relation between the interference level and the data compression indication information comprises a corresponding relation between the interference equal to and the fourth indication.

That is, if the interference level is high, the data may be compressed using a compression algorithm, and when the interference level is low, the data may not be compressed using any compression algorithm.

Alternatively, the data Compression algorithm may include an HC (Header Compression ) algorithm, which may include an EHC (ETHERNET HEADER Compression ) algorithm and/or an ROHC (Robust Header Compression, robust header Compression) algorithm, as examples.

(2) The correspondence between interference level and bearer transmission state.

Alternatively, the bearer transport state may comprise suspending or not suspending at least one bearer, wherein not suspending at least one bearer may also be understood as continuing to transport at least one bearer.

Optionally, when the interference level is below the first threshold, the correspondence between the interference level and the bearer transmission state may comprise a correspondence between the interference level and a bearer transmission state in which at least one bearer is not suspended. 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 a bearer transmission state in which at least one bearer is suspended. That is, at least one bearer may not be suspended, or may continue to be transmitted, if the interference level of the interference environment is low, but may be suspended if the interference level of the interference environment is high.

Alternatively, when suspending at least one bearer, the terminal device may choose which bearer or bearers to suspend according to actual requirements, or the network device may instruct the terminal device which bearer or bearers to suspend.

(3) Correspondence between interference level and PBR (Prioritized Bit Rate, priority rate).

Optionally, when the interference level is higher than the second threshold, the correspondence between the interference level and the PBR may include a correspondence between the interference level and the first PBR value. When the interference level is below the first threshold, the correspondence between the interference level and the PBR may include a correspondence between the interference level and a second PBR value, wherein the first PBR value is below the second PBR value. That is, a lower PBR value may be used if the number of scrambling levels is higher, and a higher PBR value may be used if the number of scrambling levels is lower.

(4) The correspondence between interference level and BSD (Bucket Size Duration, token bucket size duration).

Optionally, when the interference level is above the second threshold, the correspondence between the interference level and the BSD may include a correspondence between the interference level and the first BSD value. When the interference level is below 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, where the first BSD value is less than the second BSD value. That is, a smaller BSD value may be used if the number of scrambling levels is higher, and a larger BSD value may be used if the number of scrambling levels is lower.

(5) The correspondence between interference level and unlicensed band parameters.

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

Alternatively, the unlicensed band parameters may include FBE (Frame Based Equipment, frame-based) channel access mode or LBE (Load Based Equipment, load-based) channel access mode. For example, when the interference level is higher than the second threshold, the correspondence between the interference level and the unlicensed band parameter includes a correspondence between the interference level and the FBE channel access mode. When the interference level is lower than the first threshold, the corresponding relation between the interference level and the unlicensed band parameter comprises the corresponding relation between the interference level and the LBE channel access mode. That is, if the interference level is high, the FBE channel access method may be used, and if the interference level is low, the LBE channel access method may be used.

Optionally, the unlicensed spectrum parameter may include a first parameter value or a second parameter value of the channel access mode. For example, when the interference level is higher than the second threshold, the corresponding relation between the interference level and the unlicensed band parameter includes a corresponding relation between the interference level and a first parameter value of the channel access mode. When the interference level is lower than the first threshold, the corresponding relation between the interference level and the unlicensed band parameter comprises a corresponding relation between the interference level and a second parameter value of the channel access mode. The channel access mode may include an FBE channel access mode and/or an LBE channel access mode. That is, if the interference level is high, the first parameter value may be used when the FBE channel access scheme and/or the LBR channel access scheme is employed, and if the interference level is low, the second parameter value may be used when the FBE channel access scheme and/or the LBR channel access scheme is employed.

(6) The corresponding relation between the interference level and the data conflict configuration parameter.

Wherein the data collision configuration parameter may include a priority.

For example, when the interference level is higher than the second threshold, the correspondence between the interference level and the data collision configuration parameter may include a correspondence between the interference level and the first priority. When the interference level is below the first threshold, the correspondence between the interference level and the data collision configuration parameter may include a correspondence between the interference level and the second priority. That is, if the interference level is higher, a first priority may be configured for at least one bearer, and if the interference level is lower, a second priority may be configured for at least one bearer.

In this way, the terminal device can determine which set of parameter configuration information is used for data transmission according to the interference state of the interference environment, or the terminal device determines which set of parameter configuration information is used for data transmission according to the interference level of the interference environment.

In the embodiment of the application, the network device sends the indication message related to the interference environment of the covered unlicensed spectrum to the terminal device, so that the terminal device can determine the interference state of the interference environment according to the indication message, so as to determine whether IIoT communication can be performed in the unlicensed frequency band.

The specific implementation process of the embodiment of the present application is different according to the content included in the indication message, and the following detailed description will be provided by the following several embodiments respectively.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining an environmental status according to an exemplary embodiment, where the method may be applied to the implementation environment shown in fig. 1 and executed by a terminal device, and the method may include the following implementation steps:

Step 301, receiving an indication message sent by a network device, where the indication message includes an interference level, and the interference level includes one of at least two levels, and interference levels corresponding to different levels in the at least two levels are different.

That is, the interference level of the interference environment may be determined by the network device, after which the determined interference level is indicated to the terminal device by means of an indication message. The interference level comprises one of at least two levels, the number of levels of which may be set according to actual requirements.

Optionally, the at least two levels include a first level for indicating that the interference level of the interference environment is below a first threshold and a second level for indicating that the interference level of the interference environment is above a second threshold, the second threshold being greater than or equal to the first threshold.

That is, the at least two classes are binary, including a first class and a second class. The interference level of the interfering environment may be considered to be interference controllable when the interference level of the interfering environment is a first level and the interference of the interfering environment may be considered to be uncontrollable when the interference level of the interfering environment is a second level.

It should be noted that, here, only the at least two levels are described as binary, and in another embodiment, the at least two levels may further include multiple levels, for example, the at least two levels include a first level, a second level and a third level, where 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 classified into three levels of high, medium and low. Of course, in another embodiment, the at least two levels may include more elements, which is not limited by the embodiment of the present application.

In addition, it should be noted that in some embodiments, the interference level of the interference environment may be classified according to the interference strength, i.e. the interference level may be used to indicate the interference strength related to the interference environment.

Optionally, the indication message further includes an object identifier, where the object identifier is associated with the interference level, where the object identifier may include at least one of an identifier of a carrier, an identifier of a frequency band, an identifier of a PLMN (Public Land Mobile Network ), an identifier of a CAG (Closed Access Group, closed access group), and an identifier of a geographic area, for example.

Wherein the identification of a carrier may be used to indicate a carrier or a group of carriers and the identification of a frequency band may be used to indicate a frequency band. The identity of the PLMN may be used to indicate a PLMN, the identity of the CAG may be used to indicate a CAG, and the identity of the geographic area may be used to indicate a geographic area.

For example, taking the example that the object identifier includes a carrier, the network device may instruct the terminal device to which carrier the interference level is specific to, associate the interference level with the carrier identifier, and then send the associated interference level and carrier identifier to the terminal device.

Step 302, determining an interference state of the interference environment based on the indication message.

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

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

Step 303, determining parameter configuration information for data transmission according to the interference state.

The specific implementation of this may be referred to the relevant content in the embodiment shown in fig. 2, and the detailed description is not repeated here.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for determining an environmental status according to an exemplary embodiment, where the method may be applied to the implementation environment shown in fig. 1 and executed by a terminal device, and the method may include, but is not limited to, part or all of the following:

Step 401, receiving indication information sent by a network device, where the indication information includes at least one of a judgment condition, a judgment policy, and a rank number, where the judgment condition includes a measurement parameter related to channel quality, the judgment policy is used to indicate how to determine a judgment result based on the judgment condition, and the rank number refers to a category of interference rank included in the judgment result.

Optionally, the judging condition may include at least one of RSSI (RECEIVED SIGNAL STRENGTH Indication of received channel strength), RSRP (REFERENCE SIGNAL RECEIVING Power, reference signal received Power), RSRQ (REFERENCE SIGNAL RECEIVING Quality, reference signal received Quality), LBT (Listen Before Talk ) times, CO (Channel Occupancy, channel occupancy) and other channel Quality related measurement parameters.

Alternatively, the decision strategy may comprise how to determine the interference level when the above decision condition is above a first threshold or how to determine the interference level when the above decision condition is below a second threshold. The first threshold and the second threshold may be set according to actual requirements, 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 embodiment of the present application.

Alternatively, the number of levels may be used to indicate how many interference levels are included altogether, for example, the number of levels may be 2, or the number of levels may be an integer greater than 2.

That is, in the present embodiment, the network device may indicate the method information for judging the interference environment to the terminal device.

It should be noted that, when the indication message includes one of the above-mentioned judgment condition, judgment policy and number of levels, the terminal device may perform judgment in combination with other manners, for example, when the indication message includes the judgment condition, the terminal device may determine the interference state of the interference environment by using a default or predefined judgment policy based on the judgment condition.

Step 402, determining an interference state of the interference environment based on the indication message.

For example, when the indication message includes a judgment condition and a judgment policy, measurement may be performed according to the judgment condition to obtain a measurement result, and then, based on the measurement result and the judgment policy, an interference level of the interference environment is determined, so as to determine an interference state of the interference environment.

Optionally, based on the indication message, determining the interference state of the interference environment may further include determining the interference state of the interference environment according to the indication message and the resource to be measured.

That is, the terminal device may determine the interference state of the interference environment based on the method information configured by the network device for determining the interference environment in combination with the related information of the terminal device. For example, it is assumed that the above indication message includes a judgment condition and a judgment policy, the judgment condition includes RSRP, and the judgment policy includes determining the interference level as a first level when the judgment condition is greater than a first threshold, and determining the interference level as a second level when the judgment condition is less than a second threshold. In this way, the terminal device may measure the RSRP of the resource to be measured, and if the measured value of the RSRP is greater than the first threshold, it may determine that the interference level of the interference environment is the first level, thereby determining the interference state of the interference environment.
