Technical Field

The present disclosure relates to the field of communication technologies, and in particular, to an information transmission method, an information transmission device, a computer readable storage medium, and an electronic apparatus.

Background

The network broadcasts network configuration information related to the target modulation mode in an SIB2 (system information 2, SIB2 comprises common sub-line resource configuration information) message to enable the terminal to determine whether the target modulation mode is enabled.

However, in this method, when the network configuration is wrong, misjudgment of whether to enable the target modulation mode by the terminal is caused, so that the modulation mode finally determined by the terminal is inaccurate, and at this time, if the network schedules an MCS (Modulation and Coding Scheme, modulation coding scheme) greater than the MCS corresponding to the modulation mode finally determined by the terminal, the code rate is greater than 1, and decoding failure occurs, so that RLF (Radio Link Failure ) frequently occurs.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The network makes the terminal determine whether to enable the target modulation scheme by broadcasting configuration information related to the target modulation scheme in SIB2 (system message 2, SIB2 includes common sub-line resource configuration information) message.

Taking 64QAM (64Quadrature Amplitude Modulation,64-phase quadrature amplitude modulation) as an example of the target modulation scheme, the uplink 64QAM is a high-order modulation technique using 64QAM in the uplink transmission, and can improve the transmission rate, spectrum utilization, user peak rate, and the like. The network may let the terminal determine whether 64QAM is enabled by broadcasting the values of enable64QAM and enable64QAM v1270 in SIB2 message.

According to the 3gpp SPEC 36.331, the values of enable64QAM and enable64 qam_v1270 are true when the terminal resolves that the network supports 64QAM, and enables 64QAM. Therefore, when the values of the enable64QAM and the enable64 qam_v1270 are inconsistent, for example, if one is true and one is false, the terminal parses that the network does not support 64QAM, and the terminal disables 64QAM and degrades to 16QAM.

Since the values of the enable64QAM and the enable64 qam_v1270 should be configured as true when the network supports 64QAM, and the values of the enable64QAM and the enable64 qam_v1270 should be configured as false when the network does not support 64QAM, it can be understood that an error occurs in the network configuration when the enable64QAM and the enable64 qam_v1270 do not coincide.

The network configuration is wrong, but the network cannot really support 64QAM, so that the MCS scheduled by the network is still possibly larger, for example, larger than 20, but in this case, the terminal analyzes that the network does not support 64QAM according to the wrong network configuration, so that the terminal can disable 64QAM, use 16QAM for modulation, and the MCS scheduled by the network is larger, so that the code rate (code rate) is larger than 1, decoding failure occurs, thereby causing radio link failure, and the network connected by the terminal can drop from 4G to 2G, thereby influencing the user Internet surfing experience.

In other words, in the related art, whether to enable the target modulation scheme is determined only according to the broadcasting of the network, if 64QAM is enabled, and if the network configuration is wrong, it is still based on the network broadcasting, so that the modulation scheme determined by the terminal may be inaccurate, and further, the problem of frequent RLF may occur due to mismatching of the modulation scheme of the terminal and the MCS scheduled by the network.

In view of the above, exemplary embodiments of the present disclosure provide an information transmission method.

Next, a system architecture of the operating environment of the present exemplary embodiment will be described with reference to fig. 1.

An information transmission method in the present exemplary embodiment will be described below with reference to fig. 3, and fig. 3 shows an exemplary flow of the information transmission method, which may include:

Step S310, receiving network configuration information and a modulation coding scheme of network scheduling;

Step S320, determining a network configuration state characterized by the network configuration information, wherein the network configuration state is used for indicating the configuration state of the network to a first target modulation mode;

step S330, determining whether the terminal uses the first target modulation mode to perform information transmission according to whether the terminal supports the first target modulation mode, the network configuration state and the modulation coding scheme.

Based on the method, on one hand, the method can determine whether the terminal uses the first target modulation mode or not based on a plurality of pieces of information, so that the accuracy of enabling the first target modulation mode by the terminal can be improved; on the other hand, when determining whether the terminal enables the first target modulation mode, the method and the device use the MCS of the network scheduling, so that mismatching of the modulation mode of the terminal and the MCS of the network scheduling can be avoided to the greatest extent, and further radio link failure caused by mismatching of the modulation mode of the terminal and the MCS of the network scheduling can be avoided to the greatest extent. In combination with the above aspects, the present disclosure can improve information transmission quality.

Each step in fig. 3 is specifically described below.

Referring to fig. 3, in step S310, network configuration information and a modulation coding scheme of network scheduling are received.

In an exemplary embodiment, the network configuration information may include information for informing the terminal whether the network to which the terminal is currently connected supports the first target modulation scheme. I.e. the network configuration information corresponds to the first target modulation scheme, which may be determined based on the first target modulation scheme. The first target modulation scheme may include a modulation scheme that needs to be determined whether the terminal is to be activated.

If it is to be determined whether the terminal is 64QAM enabled, the first target modulation scheme is 64QAM. Taking the example that the first target modulation mode is 64QAM, the network configuration information includes two parameter information, which are respectively enable64QAM and enable_64qam_v1270. When the values of the enable64QAM and the enable64 qam_v1270 are true, the terminal may parse out that the network supports 64QAM.

In an exemplary embodiment, the network may send its corresponding network configuration information to the terminal upon or after the terminal accesses the network.

The network may transmit its corresponding network configuration information to the terminal in the form of a broadcast, for example. The network may broadcast its configuration information for the first target modulation scheme in a SIB2 (system message 2) message, for example. Continuing to take 64QAM as an example, the network may broadcast the values of enable64QAM and enable_64qam_v1270 in SIB1 message to send its configuration information for 64QAM to the terminal, so that the terminal may receive the configuration information of the network for the first target modulation mode.

Of course, the network may send the network configuration information to the terminal in other manners, so that the terminal receives the network configuration information. If the terminal requests uplink data transmission, the network sends the corresponding network configuration information to the terminal according to the received uplink data transmission request sent by the terminal, so that the terminal receives the network configuration information. The present exemplary embodiment is not particularly limited thereto.

In an exemplary embodiment, the modulation coding scheme of the network schedule may include an MCS (Modulation and Coding Scheme ).

The configuration of the rate in the LTE (Long Term Evolution ) network is achieved by MCS index values. The MCS uses the factor affecting the communication rate of interest as a column of the table and the MCS index as a row to form a rate table. Each MCS index corresponds to a physical transmission rate under a set of parameters.

In an exemplary embodiment, the modulation coding scheme may include an index value of the modulation coding scheme, such as an index value of the MCS.

When the terminal needs to perform uplink data transmission, the terminal can send an uplink transmission request to the network, and after receiving the uplink transmission request, the network can schedule a modulation and coding scheme according to information such as distance between the terminal and the network, and then send the currently scheduled modulation and coding scheme to the terminal, so that the terminal can receive the modulation and coding scheme scheduled by the network.

Next, in step S320, a network configuration state characterized by the network configuration information is determined.

The network configuration state is used for indicating the configuration state of the network to the first target modulation mode.

In an exemplary embodiment, the first target modulation scheme may include a 64-phase quadrature amplitude modulation scheme, namely 64QAM as described above. Of course, the first target modulation scheme may also include other modulation schemes that need to determine whether to enable at the terminal according to the configuration information of the network, which is not limited in particular in the present exemplary embodiment.

In an exemplary embodiment, the network configuration state may include 3 states, namely, a first state, a second state, and a third state.

The first state is used for indicating that the configuration state of the network for the first target modulation mode is not supported, i.e. the network does not support the first target modulation mode, the second state is used for indicating that the configuration state of the network for the first target modulation mode is supported, i.e. the network supports the first target modulation mode, and the third state is used for indicating that the configuration state of the network for the first target modulation mode is pending, i.e. the network does not configure an effective value for the first target modulation mode, i.e. whether the network supports the first target modulation mode cannot be determined according to the network configuration information at this time.

In an exemplary embodiment, the network configuration information may include a first parameter and a second parameter. That is, whether the network supports the first target modulation scheme needs to be determined by the first parameter and the second parameter together. The first parameter may be used to characterize whether an Uplink Physical shared channel (PUSCH) SHARE CHANNEL of the network supports the first target modulation scheme, and the second parameter may be used to characterize whether a terminal of the target transmission capability level supports the first target modulation scheme.

In the 3GPP 36.306 protocol, there are specified UE (User Equipment, i.e., terminal) transmission capability classes (UEcategory) for a total of 10 UE capability classes, category1 through category10 respectively, and that only category5 and category8 terminals can support uplink 64QAM. Therefore, when the first target modulation scheme is 64QAM, the target transmission capability level may include category5 and category8.

In the protocol before R12, only terminals with transmission capability levels of category 5 and category 8 are specified to support UL 64QAM (uplink 64 QAM), that is, in the protocol before R12, the network configures an enable64 qam=true in SIB2 as long as the network configures a parameter QAM64Enabled, which characterizes whether the network supports 64QAM, as a bootean_true, and both the network and the terminals simultaneously take effect of 64QAM.

The protocols after R12, terminal capability is separated up and down, and more terminals support UL 64QAM except for category 5 and category8 terminals. After R12, if the non-category 5 and non-category 8 terminals can support 64QAM, they cannot only see enable64 qam=true, but also need to see newly added cell enable_64qam_v1270, and enable64 qam=true and enable_64qam_v1270=true need to be configured in sib2 at the same time, and at this time, both the network and the terminal can take effect of 64QAM. The enable_64qam_v1270 is configured as a bootean_true depending on the base station side parameter R12QAM64 Enabled.

In the case that the network configuration information includes the first parameter and the second parameter, the specific embodiment of step S120 may include: and determining the network configuration state represented by the network configuration information according to whether the terminal supports the first target modulation mode, the state value of the first parameter and the state value of the second parameter.

A method for determining a network configuration status in an exemplary embodiment of the present disclosure is further described below in conjunction with fig. 4. Referring to fig. 4, the method may include steps S410 to S460.

In step S410, it is determined whether the terminal supports the first target modulation scheme, if not, the step S440 is performed, and if yes, the step S420 is performed;

in step S420, it is determined whether the state value of the first parameter and the state value of the second parameter are the same, if yes, the process goes to step S430, and if no, the process goes to step S460;

in step S430, it is determined whether the state value of the first parameter and the state value of the second parameter are the first state values, if yes, the process goes to step S440, otherwise the process goes to step S450;

in step S440, determining the network configuration state as a first state;

In step S450, determining the network configuration state as a second state;

In step S460, the network configuration state is determined to be a third state.

For example, when the terminal supports the first target modulation mode, the network configuration state represented by the network configuration information may be determined according to whether the state value of the first parameter and the state value of the second parameter are the same; when the terminal does not support the first target modulation mode, the network configuration state represented by the network configuration information can be directly determined to be the first state.

And when the terminal supports the first target modulation mode, determining that the network configuration state is the first state if the state value of the first parameter and the state value of the second parameter are both first state values, and determining that the network configuration state is the second state if the state value of the first parameter and the state value of the second parameter are both second state values. The first state value is false, and the second state value is true.

And when the terminal supports the first target modulation mode, if the state value of the first parameter is different from the state value of the second data parameter, determining that the network configuration state is the third state.

Taking the example that the first target modulation mode is 64QAM, the parameter 64QAM.support can be used for representing whether the terminal supports 64QAM, when the value is true, the terminal indicates support, and when the value is false, the terminal indicates non-support. Parameters 64QAMenable are used to indicate whether the network supports 64QAM, when the value is true, the network configuration supports 64QAM, and when the value is false, the network configuration does not support 64QAM; the current value null indicates that the network has not configured a valid value for whether 64QAM is supported. When the terminal supports 64QAM and the values of the enable64QAM and the enable64 QAM_v1270 are inconsistent, the value of 64QAMenable is null.

When the value of the parameter 64QAMenable is false, the network configuration state is indicated as the first state, when the value is true, the network configuration state is indicated as the second state, and when the value is null, the network configuration state is indicated as the third state.

In other words, if 64QAM. Provider=false, then 64QAMenable takes on the value false regardless of the values of enable64QAM and enable_64qam_v 1270; if 64qam.support is true, enable64 qam=true, enable_64qam_v 1270=true, then 64QAMenable =true; if 64QAM. Support=true, enable64 qam=false, enable_64qam_v 1270=false, then 64QAMenable =false; if 64QAM. Support=true, enable64 qam=false, enable_64qam_v 1270=true, then 64QAMenable =null; if 64QAM. Support=true, enable64 qam=true, enable_64qam_v 1270=false, then 64QAMenable =null. For example, the determination rules of 64QAMenable may be determined according to table 1.

Table 1 64 QAMeable determination rules

Parameters (parameters)	64QAM.support	enable64QAM	enable_64QAM_v1270	64QAMenable
					Value taking	false	true/false	true/false	false

					Value taking	true	false	false	false

					Value taking	true	true	false	null

With continued reference to fig. 3, in step S330, it is determined whether the terminal uses the first target modulation scheme for information transmission according to whether the terminal supports the first target modulation scheme, the network configuration state, and the modulation coding scheme.

Next, a specific embodiment of step S330 will be described in detail with reference to fig. 5 to 8.

Fig. 5 illustrates a flowchart of a method of determining whether a terminal uses a first target modulation scheme in an exemplary embodiment of the present disclosure. Referring to fig. 5, the method may include steps S510 to S530.

In step S510, it is determined whether the terminal supports the first target modulation scheme, if yes, the step S520 is shifted, and if not, the step S530 is shifted;

In step S520, determining whether the terminal uses the first target modulation mode for information transmission according to the network configuration state and the modulation coding scheme;

In step S530, it is determined that the terminal does not use the first target modulation scheme for information transmission.

Next, an exemplary embodiment of step S520 will be described with reference to fig. 6 to 7.

Fig. 6 is a flowchart illustrating a method for determining whether a terminal uses a first target modulation scheme according to a network configuration state and a modulation coding scheme when the terminal supports the first target modulation scheme in an exemplary embodiment of the present disclosure. The method may include steps S610 to S630. Wherein:

In step S610, the network configuration state and the priority of the modulation coding scheme are determined according to the network configuration state and the modulation coding scheme.

In an exemplary embodiment, the specific embodiment of step S610 may include: and when the network configuration state is the third state, determining that the priority of the modulation and coding scheme is higher than that of the network configuration state.

For example, when the terminal supports the first target modulation mode and the network configuration state is the third state, it may be directly determined that the priority of the modulation coding scheme is higher than the priority of the network configuration state. In this way, in the subsequent step S630, it may be determined whether the terminal uses the first target modulation scheme directly according to the modulation and coding scheme.

When the terminal supports the first target modulation mode and the network configuration state is the third state, whether the terminal uses the first target modulation mode or not is determined according to the modulation coding scheme, so that the modulation mode used by the terminal and the modulation coding scheme are matched with each other under the condition that the terminal supports the first target modulation mode, and the problem that the terminal disables the first target modulation mode because the network state is in the third state, but the network possibly calls an MCS with a large MCS corresponding to the first target modulation mode, so that decoding is failed and radio link failure frequently occurs is avoided.

In an exemplary embodiment, the specific embodiment of step S610 may further include: and when the network configuration state is the first state or the second state, determining the priority of the network configuration state and the modulation coding scheme according to the modulation coding scheme.

Specifically, it may include: when the network configuration state is the first state and the value of the modulation and coding scheme is larger than a first preset value and smaller than a second preset value, determining that the priority of the network configuration state is higher than that of the modulation and coding scheme; when the network configuration state is the first state and the value of the modulation coding scheme is greater than or equal to the second preset value, determining that the priority of the modulation coding scheme is higher than that of the network configuration state; when the network configuration state is the second state and the value of the modulation coding scheme is smaller than or equal to the first preset value, determining that the priority of the modulation coding scheme is higher than the priority of the network configuration state; the first preset value is smaller than the second preset value, and the value of the modulation coding scheme can be understood as an index value corresponding to the modulation coding scheme.

In an exemplary embodiment, the first preset value may be determined according to a correspondence between the MCS index value in the MCS table and the first target modulation scheme, and the first preset value may be understood as a minimum value of the corresponding MCS index value when the first target modulation scheme may be used. For example, when the MCS is greater than or equal to 20, the first target modulation scheme may be supported, and the first preset value may be 20. When the MCS is greater than or equal to 15, the first target modulation scheme may be supported, and the first preset value may be 15.

The second preset value may be determined empirically or in actual condition. For example, when the MCS value is greater than 20, if the probability of the radio link failure caused by the terminal not enabling the first target modulation scheme is less than a preset error value, such as 1%, in a range where the MCS is greater than 20 and less than a certain value a (the value is greater than 20), the value a may be determined as the second preset value.

The inventors of the present application found in the study that, for 64QAM, 64QAM can be used when MCS is more than 20 according to its corresponding MCS table, but when MCS is more than 20 and less than 24, the terminal uses 16QAM and uses 64QAM have little influence on the user's internet experience. Therefore, when the first target modulation scheme is 64QAM, the second preset value may be 24.

In the disclosure, when a terminal supports a first target modulation mode, if the network configuration state is the first state and the value of the modulation and coding scheme is greater than a first preset value and less than a second preset value, determining that the priority of the network configuration state is higher than the modulation and coding scheme. In other words, when the terminal supports the first target modulation mode, but the network configuration state indicates that the network does not support the first target modulation mode, even if the network invokes an MCS matching the first target modulation mode, if the MCS is within the second preset value, determining whether the terminal uses the first target modulation mode according to the indication of the network configuration state. As described above, since whether the first target modulation scheme is started has little influence on the user experience and does not cause frequent radio link failure when the MCS is within the range of the first preset value and the second preset value, if it is determined that the priority of the network configuration state is higher than the modulation and coding scheme, the indication of the network can be followed as much as possible while avoiding frequent radio link failure.

As described above, in the present disclosure, when a terminal supports a first target modulation scheme, if the value of the modulation coding scheme is greater than or equal to the second preset value in the network configuration state is the first state, it is determined that the priority of the modulation coding scheme is higher than the network configuration state. This is because when the modulation and coding scheme is greater than the second preset value, it means that the network schedules a larger MCS, and based on what will be described in step S620, if the network configuration state is the first state according to the indication of the network configuration state, the terminal disables the first target modulation scheme. At this time, the terminal may degrade the use of other modulation schemes, and the aforementioned problem of frequent radio link failure may occur. Therefore, in order to avoid frequent radio link failure, the terminal should enable a modulation scheme matching with the MCS, and thus, in this case, it may be determined that the priority of the modulation coding scheme is higher than the network configuration state, so that the terminal enables a modulation scheme matching with the terminal according to the current value of the MCS.

As described above, in the present disclosure, when the terminal supports the first target modulation scheme, if the network configuration state is the second state and the value of the modulation coding scheme is less than or equal to the first preset value, it is determined that the priority of the modulation coding scheme is higher than the priority of the network configuration state. This is because, in this case, if the inventor of the present application indicates whether the terminal starts the first target modulation mode according to the network configuration state, it can be known based on the following content in step S620 that, since the network configuration state is the second state, the terminal starts the first target modulation mode, but at this time, the MCS of the network scheduling is smaller, which is not matched with the first target modulation mode, and packet loss occurs, and decoding fails, which also affects the internet surfing experience of the user. Therefore, at this time, it may be determined that the priority of the modulation and coding scheme is higher than the network configuration state so that the modulation scheme used by the terminal matches the modulation and coding scheme.

It should be noted that, in the present application, when the terminal supports the first target modulation mode and the network configuration state is the second state, and the value of the modulation and coding scheme is smaller than or equal to the first preset value, if the priority of the network configuration state is higher than the priority of the modulation and coding scheme, that is, the terminal enables the first target modulation mode, although the packet loss occurs due to the mismatch between the MCS of the network scheduling and the first target modulation mode used by the terminal, the probability of the packet loss is smaller, so that it may also be determined that the priority of the network configuration state is higher than the modulation and coding scheme. In this way, the indication of the network can be followed as much as possible while avoiding frequent radio link failures.

Next, step S610 described above is further described with reference to fig. 7. Fig. 7 illustrates a flowchart of a method of determining network configuration status and priority of modulation coding schemes in an exemplary embodiment of the present disclosure. Referring to fig. 7, the method may include steps S701 to S708.

In step S701, it is determined whether the network configuration state is the third state, if so, the process goes to step S707, and if not, the process goes to step S702;

In step S702, it is determined whether the network configuration state is the first state, if so, the process goes to step S703, and if not, the process goes to step S706;

In step S703, it is determined whether the value of the modulation and coding scheme is greater than or equal to a second preset value, if yes, the step S707 is shifted, and if no, the step S704 is shifted;

in step S704, it is determined whether the value of the modulation and coding scheme is greater than a first preset value, if yes, the step is transferred to step S705, and if not, the step is transferred to step S708;

in step S705, it is determined that the priority of the network configuration state is higher than the priority of the modulation coding scheme;

In step S706, it is determined whether the value of the modulation and coding scheme is less than or equal to the first preset value, if yes, the step S707 is proceeded to, if no, the step S708 is proceeded to;

in step S707, it is determined that the priority of the modulation coding scheme is higher than the priority of the network configuration state;

In step S708, it is determined that the priority of the modulation coding scheme and the priority of the network configuration state are the same.

When the terminal supports the first target modulation mode, the network configuration state is the second state, and the value of the modulation and coding scheme is greater than the first preset value, the indication result of whether the first target modulation mode is used by the terminal by the modulation and coding scheme is the same as the indication result of whether the first target modulation mode is used by the terminal by the network configuration state, and when the terminal supports the first target modulation mode, the network configuration state is the first state, and the value of the modulation and coding scheme is less than or equal to the first preset value, the indication result of whether the first target modulation mode is used by the terminal by the modulation and coding scheme is the same as the indication result of whether the first target modulation mode is used by the terminal by the network configuration state. At this time, the priorities of the two may be configured to be the same in step S708, or may be arbitrarily configured (e.g., the modulation coding scheme priority is higher than the network configuration state or the network configuration state priority is higher than the modulation coding scheme), or the priority may be determined when the two indication results are the same, and the priority may be determined when the two indication results are different, which is not particularly limited in this exemplary embodiment.

Next, with continued reference to fig. 6, in step S620, if the priority of the network configuration state is higher than the priority of the modulation and coding scheme, it is determined whether the terminal uses the first target modulation scheme for information transmission according to the network configuration state.

In an exemplary embodiment, the determining, according to the network configuration state, whether the terminal uses the first target modulation mode to perform information transmission includes: when the network configuration state is the first state, determining that the terminal does not use the first target modulation mode for information transmission; and when the network configuration state is the second state, determining that the terminal uses the first target modulation mode to transmit information.

For example, when the network configuration state is the first state, the network does not support the first target modulation mode, so the terminal may be instructed not to use the first target modulation mode at this time; when the network configuration state is the second state, the network supports the first target modulation scheme, so that the terminal can be instructed to use the first target modulation scheme at this time.

With continued reference to fig. 6, in step S630, if the priority of the modulation and coding scheme is higher than the priority of the network configuration state, it is determined whether the terminal uses the first target modulation scheme for information transmission according to the modulation and coding scheme.

In an exemplary embodiment, determining whether the terminal uses the first target modulation mode for information transmission according to the modulation coding scheme includes: when the value of the modulation and coding scheme is smaller than or equal to the first preset value, the terminal is instructed not to use the first target modulation mode for information transmission; and when the value of the modulation and coding scheme is larger than the first preset value, the terminal is instructed to use the first target modulation mode to transmit information.

Fig. 8 illustrates a flowchart of a method of determining a modulation scheme used by a terminal according to a modulation coding scheme in an exemplary embodiment of the present disclosure, and referring to fig. 8, the method may include steps S810 to S850.

In step S810, it is determined whether the value of the modulation and coding scheme is greater than a first preset value, if yes, the step is transferred to step S820, and if not, the step is transferred to step S830;

in step S820, the terminal is instructed to perform information transmission using the first target modulation method;

In step S830, it is determined whether the value of the modulation and coding scheme is greater than a third preset value, if yes, the step is turned to step S840, if not, the step is turned to step S850;

in step S840, the terminal is instructed to perform information transmission using a second target modulation scheme;

in step S850, the terminal is instructed to perform information transmission using the third target modulation scheme.

In an exemplary embodiment, the third preset value is smaller than the first preset value. The third preset value may be determined according to a minimum index value in the MCS table, which may use the second target modulation scheme. If the second target modulation scheme may be used when the MCS index value is greater than or equal to 10 and less than 20, the third preset value may be 10. The modulation order of the second target modulation mode is smaller than that of the first target modulation mode, and the modulation order of the third target modulation mode is smaller than that of the second target modulation mode.

For example, when the first target modulation scheme is 64QAM, the second target modulation scheme may be 16QAM, and the third target modulation scheme may be QPSK.

For example, another embodiment of step S520 may include: and when the network configuration state is the second state and the value of the modulation and coding scheme is smaller than or equal to the first preset value, determining that the terminal does not use the first target modulation mode for information transmission.

For example, as can be seen from the foregoing descriptions in steps S620 and 630, when the network configuration state is the second state and the value of the modulation and coding scheme is greater than or equal to the foregoing predetermined value, the terminal is required to use the first target modulation scheme according to the network configuration state, the terminal is required to not use the first target modulation scheme according to the value of the coding and modulation scheme, and the indication results of the two are inconsistent. However, considering that the code modulation scheme of the network scheduling is smaller at this time, if the terminal is instructed to use the first target modulation mode to perform information transmission, the packet loss situation occurs, so that decoding failure is also caused, and the problem of radio link failure occurs. Therefore, at this time, in order to avoid this, the terminal is instructed not to use the first target modulation scheme for information transmission.

However, as described above, according to the studies of the present inventors, it was found that, at this time, although packet loss occurs, the frequency of occurrence of packet loss is not large, so that the terminal may be determined to use the first target modulation scheme following the network instruction, and this is not particularly limited in this exemplary embodiment.

For example, another embodiment of step S520 may include: and when the network configuration state is the second state and the value of the modulation and coding scheme is larger than the first preset value, determining that the terminal uses the first target modulation mode to transmit information.

For example, as can be seen from the foregoing descriptions in steps S620 and 630, when the network configuration state is the second state and the value of the modulation and coding scheme is greater than the first preset value, the terminal is instructed to use the first target modulation scheme according to the network configuration state, and the terminal is instructed to use the first target modulation scheme according to the modulation and coding scheme, and the two instruction results are the same, so that it can be finally determined that the terminal uses the first target modulation scheme for information transmission.

For example, another embodiment of step S520 may include: and when the network configuration state is the first state and the value of the modulation and coding scheme is smaller than a second preset value, determining that the terminal does not use the first target modulation mode for information transmission.

For example, as can be seen from the foregoing contents of steps S620 and 630, when the network configuration state is the first state and the value of the modulation and coding scheme is smaller than the second preset value, the terminal is instructed not to use the first target modulation scheme according to the network configuration state, and when the modulation and coding scheme is greater than the first preset value and smaller than the second preset value, the terminal is instructed to use the first target modulation scheme according to the modulation and coding scheme, but as described above, since whether the terminal uses the first target modulation scheme at this time has little influence on the user' S internet surfing experience, that is, even if the first target modulation scheme is not used, the frequency of occurrence of radio link failure is small, so that at this time, the terminal can follow the network instruction as much as possible and determine that the terminal does not use the first target modulation scheme. In this way, network indications can be followed as much as possible while avoiding frequent radio link failures.

For example, another embodiment of step S520 may include: and when the network configuration state is the first state and the value of the modulation and coding scheme is greater than or equal to the second preset value, determining that the terminal uses the first target modulation mode to transmit information.

For example, as can be seen from the foregoing descriptions in steps S620 and 630, when the network configuration state is the first state and the value of the modulation and coding scheme is greater than or equal to the second preset value, the terminal is instructed not to use the first target modulation scheme according to the network configuration state, and the terminal is instructed to use the first target modulation scheme according to the modulation and coding scheme, and the two instruction results are inconsistent. If the terminal does not use the first target modulation scheme, the problem of frequent failure of the wireless link as described above occurs due to a large modulation and coding scheme of network scheduling, and in order to avoid this problem, it is determined that the terminal uses the first target modulation scheme at this time.

For example, another embodiment of step S520 may include: and when the network configuration state is the third state and the value of the modulation and coding scheme is smaller than or equal to the first preset value, determining that the terminal does not use the first target modulation mode for information transmission.

For example, another embodiment of step S520 may include: and when the network configuration state is the third state and the value of the modulation and coding scheme is larger than the first preset value, determining that the terminal uses the first target modulation mode to transmit information.

For example, when the network configuration state is the third state, that is, when a network configuration error occurs, at this time, whether the first target modulation mode is used or not may be determined according to the code modulation scheme, that is, when the code modulation scheme is smaller than the first preset value, it is determined that the terminal does not use the first target modulation mode, and when the value of the code modulation scheme is greater than the first preset value, it is determined that the terminal uses the first target modulation mode, so that the code modulation scheme and the modulation mode used by the terminal may be matched, and the problem that the terminal cannot start the first target modulation mode according to the network configuration state and thus causes frequent radio link failure due to the large MCS of the network schedule is avoided.

Next, the information transmission method of the present disclosure will be further described by taking the example that the first target modulation scheme is 64 QAM.

For example, the coded modulation scheme may be divided into a first level, a second level, and a third level according to the first preset value and the second preset value, and the corresponding MCS _L、MCS_M、MCS_H is used. Taking the first preset value of 20 and the second preset value of 24 as an example, the range of values of each level of MCS can be as shown in table 2.

Table 2 range of MCS level values

Grade	MCS_L	MCS_M	MCS_H
				Value range	MCS<＝20	20<MCS<24	MCS>＝24

Taking the example that the parameters 64QAM _.support are used for representing whether the terminal supports 64QAM and the parameters 64QAM _enable are used for representing the network configuration state, whether the terminal starts 64QAM currently can be determined according to the 64QAM _.support、64QAM_enable and the MCS level.

Specifically, when 64QAM _.support is false, that is, the terminal does not support 64QAM, it may be directly determined that the terminal does not use 64QAM, and directly degraded to use 16QAM, and specific rules corresponding to the method are shown in table 3. That is, at this time, the 64QAM _enable and MCS level are not judged, and it is directly determined that the terminal does not use 64QAM.

TABLE 3 64QAM dynamic switch State Table for terminal 64QAM when the support is false

Parameters (parameters)	64QAM_.support	64QAM_enable	MCS level	64QAM
					Value taking	false	true/false/null	MCS_L/MCS_M/MCS_H	disable

When 64QAM _.support is true, i.e., the terminal supports 64QAM, and 64QAMenable is not null, i.e., the network broadcasts a valid value configured by the network for 64QAM in SIB2 message, it may be determined whether the terminal uses 64QAM based on table 4.

Table 464 QAM support is true,64QAMenable is not null,64QAM dynamic switch State Table

Parameters (parameters)	64QAM_.support	64QAM_enable	MCS level	64QAM
					Value taking	true	true	MCS_L	disable
Value taking	true	true	MCS_M	enable
					Value taking	true	true	MCS_H	enable
Value taking	true	false	MCS_L	disable
					Value taking	true	false	MCS_M	disable
Value taking	true	false	MCS_H	enable

At 64qam.support is true and 64QAMenable is null, i.e. the network can determine whether the terminal uses 64QAM based on table 5 when SIB2 message broadcasts invalid configuration information for the network configuration for 64QAM.

Table 5 64QAM support is true,64QAMenable is null,64QAM dynamic handoff status table

Parameters (parameters)	64QAM_.support	64QAM_enable	MCS level	64QAM
					Value taking	true	null	MCS_L	disable
Value taking	true	null	MCS_M	enable
					Value taking	true	null	MCS_H	enable

In tables 3 to 5, when the 64QAM value is disable, the terminal is not used, and when the 64QAM value is enable, the terminal is used with 64QAM.

Taking the example of the value of 64QAM _.support being true, the value of enable64QAM being false, the value of enable64 QAM_v1270 being true, the value of MCS being 26, the value of 64QAM _.support being true, the value of enable64QAM being false, the value of enable64 QAM_v1270 being true, the value of 64QAM _enable should be null according to Table 1. If the value of MCS is 26, the level of MCS is MCS _H.64QAM_support, the value of 64QAM _enable is true, and the level of MCS is MCS _H according to table 2, and if the level of MCS is 64QAM is enabled according to table 5, it is determined that the terminal uses the first target modulation scheme.

Next, fig. 9 shows a flowchart of a method of determining whether a terminal enables 64QAM in an exemplary embodiment of the present disclosure. Referring to fig. 9, the method may include steps S901 to S908.

In step S901, it is determined whether the terminal supports 64QAM, if yes, the process goes to step S902, and if no, the process goes to step S908;

In step S902, it is determined whether the values of enable64QAM and enable64 qam_v1270 are identical, if yes, the process goes to step S903, if no, the process goes to step S906;

In step S903, it is determined whether the values of the enable64QAM and the enable64 qam_v1270 are true, if not, the process goes to step S904, if yes, the process goes to step S905;

In step S904, it is determined whether the MCS level is MCS _H, if yes, the process goes to step S907, otherwise, the process goes to step S908;

In step S905, it is determined whether the MCS level is MCS _L, and if not, the process proceeds to step S907; if yes, go to step S908;

In step S906, it is determined whether the MCS level is MCS _L, if yes, the process goes to step S908, and if no, the process goes to step S907;

In step S907, it is determined that the terminal uses 64QAM;

In step S908, it is determined that the terminal does not use 64QAM.

In the method, whether the terminal uses the first target modulation mode is determined by whether the terminal supports the first target modulation mode, the network configuration state and the code modulation scheme, so that accuracy of determining whether the terminal uses the first target modulation mode can be improved, the problem of frequent radio link failure caused by mismatching of the modulation mode used by the terminal and the modulation coding scheme of network scheduling is avoided, the terminal drops to 2G, and user experience is affected.

Meanwhile, when the network configures an effective value for the first target modulation scheme, that is, when the network configuration state is the first state or the second state, the network instruction is followed as much as possible. For example, in the case where the MCS is greater than 20 and less than 24, for example, the frequency of occurrence of radio link failure is low even if the terminal does not use 64QAM, so that the terminal may follow the network instruction at this time, that is, if the network configuration status indicates that the terminal uses the first target modulation scheme, the terminal starts the first target modulation scheme, and if the network status indicates that the terminal does not use the first target modulation scheme, the terminal does not start the first target modulation scheme. Therefore, network configuration is met as much as possible while ensuring the user surfing experience.

Further, in the present disclosure, based on the third state of the network configuration state, that is, in the case where the network does not configure a valid value for the first target modulation scheme, that is, in the case where the network has an erroneous configuration, whether the terminal uses the first target modulation scheme may be indicated by the value of the MCS. That is, the present disclosure may recover from a network configuration error to reasonably determine whether the terminal uses the first target modulation scheme.

In summary, the information transmission method of the present disclosure improves user experience and satisfies network configuration.
