Background

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

However, in the case of an error in network configuration, the method may cause a misjudgment of whether the terminal enables the target Modulation Scheme, so that the Modulation Scheme finally determined by the terminal is inaccurate, and at this time, if the network schedules a Modulation and Coding Scheme (MCS) larger than an MCS corresponding to the Modulation Scheme finally determined by the terminal, a Coding rate (code rate) may be larger than 1, a decoding Failure may occur, and Radio Link Failure (RLF) may frequently occur.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different 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 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 their repetitive description 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 the form of 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 lets the terminal determine whether to enable the target modulation scheme by broadcasting configuration information related to the target modulation scheme in a 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 method, uplink 64QAM is a high-order Modulation technique that adopts 64QAM in uplink transmission, and can improve transmission rate, spectrum utilization rate, user peak rate, and the like. The network may let the terminal determine whether 64QAM is enabled by broadcasting the values of enable64QAM and enable _64QAM _ v1270 in the SIB2 message.

According to the 3gpp SPEC 36.331, supporting UL64QAM (uplink 64QAM), the values of enable64QAM and enable _64QAM _ v1270 are both true (true), at this time, the terminal analyzes that the network supports 64QAM, and then 64QAM is enabled. Therefore, when the values of enable64QAM and enable _64QAM _ v1270 are not consistent, such as one is true and one is false, the terminal resolves that the network does not support 64QAM, and the terminal disables 64QAM and downgrades to 16 QAM.

Since the values of enable64QAM and enable _64QAM _ v1270 should be configured to true when the network supports 64QAM and configured to false when 64QAM is not supported, it can be understood that an error occurs in the network configuration when the enable64QAM and the enable _64QAM _ v1270 are not identical.

However, in this case, the terminal analyzes that the network does not support 64QAM according to the wrong network configuration, so that the terminal disables 64QAM and uses 16QAM for modulation, and the MCS for network scheduling is large, so that a code rate (code rate) is greater than 1, decoding failure occurs, and a radio link fails, and a network connected to the terminal falls from 4G to 2G, which affects user experience on the internet.

In other words, in the related art, it is determined whether to enable the target modulation scheme, for example, whether to enable64QAM, only according to the broadcast of the network, and if the network configuration is incorrect, it still takes the broadcast of the network as the standard, so that the modulation scheme determined by the terminal may be inaccurate, and the modulation scheme of the terminal may not match with the MCS scheduled by the network, thereby causing a problem of frequent RLF.

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

Next, the system architecture of the operating environment of the exemplary embodiment will be described in conjunction with fig. 1.

Fig. 1 shows a schematic diagram of a system architecture, which system architecture 100 may include a terminal 110 and a network device 120.

The terminal 110 and the network device 120 may form a connection through a wired or wireless communication link to perform data interaction.

In an exemplary embodiment, the method described above may be performed by the terminal 110. For example, the terminal may receive the network configuration information and the MCS scheduled by the network, then determine the configuration state of the network for the first target modulation scheme according to the network configuration information, and then determine whether the terminal enables the first target modulation scheme for information transmission according to whether the terminal supports the first target modulation scheme, the configuration state of the network for the first target modulation scheme, and the MCS scheduled by the network.

The information transmission method in the present exemplary embodiment is described below with reference to fig. 3, where 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 represented by the network configuration information, where the network configuration state is used to indicate a configuration state of the network for a first target modulation mode;

step S330, determining whether the terminal uses the first target modulation mode for 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 based on a plurality of pieces of information, so that the accuracy of enabling the terminal to the first target modulation mode can be improved; on the other hand, when determining whether the terminal enables the first target modulation scheme, the present disclosure uses the network scheduled MCS, so that the modulation scheme of the terminal and the network scheduled MCS may be prevented from being mismatched to the maximum extent, and further, the radio link failure due to the mismatch between the modulation scheme of the terminal and the network scheduled MCS may be prevented to the maximum extent. In sum, the present disclosure may improve information transmission quality.

Each step in fig. 3 is explained in detail below.

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

In an exemplary embodiment, the network configuration information may include information for informing the terminal whether a network to which the terminal currently accesses 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 enabled.

If it is determined whether the terminal enables 64QAM, the first target modulation scheme is 64QAM. Taking 64QAM as an example as the first target modulation scheme, the network configuration information includes two pieces of parameter information, which are enable64QAM and enable _64QAM _ v1270 respectively. When the values of enable64QAM and enable _64QAM _ v1270 are both true, the terminal can analyze that the network supports 64QAM.

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

Illustratively, the network may transmit its corresponding network configuration information to the terminal in a broadcast manner. For example, the network may broadcast its configuration information for the first target modulation scheme in a SIB2 (system message 2) message. Continuing with the 64QAM example, the network may broadcast the values of enable64QAM and enable _64QAM _ v1270 in a 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 scheme.

Of course, the network may also send the network configuration information to the terminal in other manners, so that the terminal receives the network configuration information. If the terminal requests to perform 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 in this regard.

In an exemplary embodiment, the Modulation and Coding Scheme scheduled by the network may include MCS (Modulation and Coding Scheme).

The rate configuration in an LTE (Long Term Evolution) network is implemented by an MCS index value. The MCS forms a rate table by using the MCS index as a row and the column of a table of factors that affect the communication rate. Therefore, each MCS index actually 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.

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

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

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

In an exemplary embodiment, the first target modulation scheme may include a 64-phase quadrature amplitude modulation scheme, i.e., 64QAM described above. Of course, the first target modulation scheme may also include other modulation schemes that need to be determined according to the configuration information of the network, and this exemplary embodiment is not particularly limited in this respect.

In an exemplary embodiment, the network configuration state may include 3 states of the first state, the second state, and the 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, that is, 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, that is, 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, that is, the network does not configure an effective value for the first target modulation mode, that is, at this time, whether the network supports the first target modulation mode cannot be determined according to the network configuration information.

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 or not needs to be determined by the first parameter and the second parameter together. The first parameter may be used to characterize whether a PUSCH (Physical Uplink shared 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.

The 3GPP 36.306 protocol specifies transmission capability classes (UEcategory) of UEs (User Equipment, i.e. terminals), which have 10 UE capability classes, i.e. category1 to category10, respectively, and specifies 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 category 8.

In the previous protocol of R12, only terminals with transmission capability levels of category5 and category8 are specified to support UL64QAM (uplink 64QAM), that is, in the previous protocol of R12, as long as the network configures a parameter QAM64Enabled, which characterizes whether the network supports 64QAM, as bold _ TRUE, the network configures enable64QAM in SIB2 as TRUE, and at this time, both the network and the terminal take effect of 64QAM at the same time.

R12 later, the terminal capability is separated up and down, and more terminals support UL64QAM except for category5 and category8 terminals. After R12, whether non-category 5 and non-category 8 terminals can support 64QAM cannot only see enable64QAM, but also needs to see newly added cell enable _64QAM _ v1270, and SIB2 needs to configure enable64QAM _ true and enable _64QAM _ v1270 at the same time, at this time, both the network and the terminal can validate 64QAM. The enable _64QAM _ v1270 is configured to be BOOLEAN _ TRUE only by being configured according to a base station side parameter R12QAM64 Enable.

In the case that the network configuration information includes the first parameter and the second parameter, a specific implementation 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 with reference to 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, go to step S440, and if yes, go to step S420;

in step S420, determining whether the state value of the first parameter is the same as the state value of the second parameter, if yes, going to step S430, and if no, going to step S460;

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

in step S440, determining that the network configuration status is a first status;

in step S450, determining that the network configuration status is a second status;

in step S460, the network configuration status is determined to be a third status.

For example, when the terminal supports the first target modulation scheme, the network configuration state represented by the network configuration information may be determined according to whether the state value of the first parameter is the same as the state value of the second parameter; when the terminal does not support the first target modulation mode, it may directly determine that the network configuration state represented by the network configuration information is the first state.

When the terminal supports the first target modulation mode, if the state value of the first parameter and the state value of the second parameter are both first state values, the network configuration state is determined to be the first state, and if the state value of the first parameter and the state value of the second parameter are both second state values, the network configuration state is determined to be the second state. 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 64QAM as an example as the first target modulation mode, a parameter 64qam.support may be used to represent whether the terminal supports 64QAM, which indicates support when the value is true, and indicates support when the value is false. Using a parameter 64QAMENABLE to represent whether the network supports 64QAM, when the value is true, representing that the network configuration supports 64QAM, and when the value is false, representing that the network configuration does not support 64 QAM; when the current value is null, the network is not configured with a valid value for whether 64QAM is supported. When the terminal supports 64QAM and the values of enable64QAM and enable _64QAM _ v1270 are inconsistent, the value of 64 QAMonable is null.

The parameter 64QAMenable may correspond to different network configuration states when it takes different values, and when it takes false, it indicates that the network configuration state is the first state, when it takes true, it indicates that the network configuration state is the second state, and when it takes null, it indicates that the network configuration state is the third state.

In other words, if 64 qam.super is false, the value of 64QAMenable is false regardless of the values of enable64QAM and enable _64QAM _ v 1270; if the support is true 64QAM, enable64QAM is true, enable _64QAM _ v1270 is true, then 64QAMenable is true; if 64QAM, supported, enabled 64QAM, enabled _64QAM _ v1270 is false, 64QAMenable is false; if 64QAM, supported, enabled 64QAM, enabled _64QAM _ v1270, then 64QAMenable is null; if 64 qam.supported is true, enable64QAM is true, enable _64QAM _ v1270 is false, 64QAMenable is null. For example, the determination rule of 64QAMenable may be determined according to table 1.

Table 164 QAMENABLE determination rules

Parameter(s)	64QAM.support	enable64QAM	enable_64QAM_v1270	64QAMenable
					Value taking	false	true/false	true/false	false
Value taking	true	true	true	true
					Value taking	true	false	false	false
Value taking	true	false	true	null
					Value taking	true	true	false	null

With 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 status, and the modulation and coding scheme.

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

Fig. 5 shows a flowchart of a method for 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, go to step S520, and if no, go to step S530;

in step S520, determining whether the terminal uses the first target modulation scheme for information transmission according to the network configuration status and the modulation and 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 is described with reference to fig. 6 to 7.

Exemplarily, fig. 6 shows a flowchart of a method for determining whether a terminal uses a first target modulation scheme according to a network configuration state and a modulation and 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, priorities of the network configuration status and the modulation and coding scheme are determined according to the network configuration status and the modulation and coding scheme.

In an exemplary embodiment, the specific implementation manner 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 scheme and the network configuration state is the third state, it may be directly determined that the priority of the modulation and 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 is determined according to the modulation coding scheme, and under the condition that the terminal supports the first target modulation mode, the modulation mode and the modulation coding scheme used by the terminal can be matched with each other, so that the problem that the terminal disables the first target modulation mode due to the fact that the network state is in the third state, but the network may call a MCS which is large in MCS and corresponds to the first target modulation mode, decoding failure is caused, and radio link failure frequently occurs is avoided.

In an exemplary embodiment, the specific implementation manner 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, the method may include: when 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; 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 priority of the modulation and coding scheme is higher than the network configuration state; 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 priority of the modulation and coding scheme is higher than that of the network configuration state; wherein, 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 corresponding relationship 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 then 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 then the first preset value may be 15.

The second preset value may be determined empirically or as a practical matter. For example, when the MCS value is greater than 20, if the probability of radio link failure caused by the terminal not enabling the first target modulation scheme is less than a preset error value, such as 1%, within a range that 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 inventor of the present application finds in research that for 64QAM, according to the corresponding MCS table, when the MCS is greater than 20, 64QAM may be used, but when the MCS is greater than 20 and less than 24, the influence of using 16QAM and using 64QAM by the terminal on the user internet experience is not great. Therefore, when the first target modulation scheme is 64QAM, the second preset value may be 24.

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

As described above, in this disclosure, when a terminal supports a first target modulation scheme, if the network configuration state is the first state, and a value of the modulation and coding scheme is greater than or equal to the second preset value, it is determined that a priority of the modulation and 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 the following content in step S620, if the network configuration status is the first status according to the indication of the network configuration status, 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 the MCS, and therefore, in this case, it may be determined that the priority of the modulation and coding scheme is higher than the network configuration state, so that the terminal enables a modulation scheme matching the terminal according to the current value of the MCS.

As described above, in the present disclosure, when a terminal supports a first target modulation scheme, if the network configuration state is the second state and the value of the modulation and coding scheme is less than or equal to the first preset value, it is determined that the priority of the modulation and coding scheme is higher than the priority of the network configuration state. This is because, the inventor of the present application finds in research that, in this case, if whether the terminal enables the first target modulation scheme is indicated according to the network configuration state, based on the content in step S620 described below, the terminal enables the first target modulation scheme because the network configuration state is the second state, but the MCS of the network scheduling is smaller, which is not matched with the first target modulation scheme, a packet loss occurs, a decoding failure also occurs, and the internet access experience of the user is also affected. Therefore, at this time, it may be determined that the modulation and coding scheme has a higher priority than the network configuration state, so that the modulation scheme and the modulation and coding scheme used by the terminal are matched.

It should be noted that, in a study, the inventor of the present application finds that, when the terminal supports the first target modulation scheme, 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, if the priority of the network configuration state is higher than the priority of the modulation coding scheme, the terminal is enabled to use the first target modulation scheme, although the MCS for network scheduling is not matched with the first target modulation scheme used by the terminal, a situation of packet loss occurs, but the probability of packet loss is small, so that it may also be determined that the priority of the network configuration state is higher than the modulation coding scheme at this time. In this way, it is possible to try to follow the network's instructions while avoiding frequent radio link failures.

Next, the above step S610 will be further described with reference to fig. 7. Fig. 7 shows a flowchart of a method of determining a network configuration status and a priority of a modulation coding scheme 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 status is the third status, if yes, go to step S707, and if no, go to step S702;

in step S702, determining whether the network configuration state is the first state, if so, going to step S703, and if not, going to step S706;

in step S703, determining whether the value of the modulation and coding scheme is greater than or equal to a second preset value, if so, going to step S707, and if not, going to step S704;

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

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

in step S706, determining whether the value of the modulation and coding scheme is less than or equal to the first preset value, if so, going to step S707, otherwise, going to step S708;

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

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

It should be noted that, when the terminal supports the first target modulation scheme, the network configuration state is the second state, and the value of the modulation coding scheme is greater than the first preset value, the result of indicating whether the terminal uses the first target modulation scheme by the modulation coding scheme is the same as the result of indicating whether the terminal uses the first target modulation scheme by the network configuration state, and similarly, when the terminal supports the first target modulation scheme, the network configuration state is the first state, and the value of the modulation coding scheme is less than or equal to the first preset value, the result of indicating whether the terminal uses the first target modulation scheme by the modulation coding scheme is the same as the result of indicating whether the terminal uses the first target modulation scheme by the network configuration state. At this time, the priorities of the two may be configured to be the same in step S708, or configured arbitrarily (for example, the modulation and coding scheme has a higher priority than the network configuration state or the network configuration state has a higher priority than the modulation and coding scheme), or when the indication results of the two are the same, the priorities are not determined, and when the indication results of the two are different, the priorities are determined, which is not particularly limited in the present exemplary embodiment.

Next, with continuing reference to fig. 6, in step S620, if the priority of the network configuration status 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 status.

In an exemplary embodiment, the determining whether the terminal uses the first target modulation scheme for information transmission according to the network configuration status 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 for information transmission.

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

With 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 scheme for information transmission according to the modulation and coding scheme includes: when the value of the modulation coding scheme is smaller than or equal to the first preset value, indicating the terminal not to use the first target modulation mode for information transmission; and when the value of the modulation coding scheme is greater than the first preset value, indicating the terminal to use the first target modulation mode for information transmission.

Fig. 8 shows a flowchart of a method for determining a modulation scheme used by a terminal according to a modulation and 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, determining whether a value of the modulation and coding scheme is greater than a first preset value, if yes, going to step S820, and if not, going to step S830;

in step S820, instructing the terminal to use the first target modulation method for information transmission;

in step S830, it is determined whether the value of the modulation and coding scheme is greater than a third preset value, if so, go to step S840, otherwise, go to step S850;

in step S840, instructing the terminal to use a second target modulation scheme for information transmission;

in step S850, the terminal is instructed to use a third target modulation scheme for information transmission.

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 of the MCS table that may use the second target modulation scheme. If the second target modulation scheme can 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 less 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, based on the above-mentioned contents in steps S620 and S630, when the network configuration status is the second status and the value of the modulation and coding scheme is greater than or equal to the preset value, the terminal is required to use the first target modulation scheme according to the network configuration status, and the terminal is required not to use the first target modulation scheme according to the value of the modulation and coding scheme, and the indication results of the two are inconsistent. However, considering that the coding modulation scheme of the network scheduling is small at this time, if the terminal is instructed to use the first target modulation scheme for information transmission, packet loss occurs, which may also cause decoding failure and radio link failure. Therefore, in this case, in order to avoid this, the terminal is instructed not to transmit information using the first target modulation scheme.

However, as described above, the inventors of the present application have found that, although packet loss may occur at this time, the frequency of occurrence of packet loss is not large, and therefore, it may be determined that the terminal uses the first target modulation scheme according to a network instruction, which is not particularly limited in the present 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 greater than the first preset value, determining that the terminal uses the first target modulation mode for information transmission.

For example, based on the content in the above steps S620 and S630, when the network configuration status is the second status 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 status, and the terminal is also instructed to use the first target modulation scheme according to the modulation and coding scheme, and the instruction results of the two 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, based on the content in the above steps S620 and S630, 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. In this way, it is possible to try to follow the network indication 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 for information transmission.

For example, based on the content in the above steps S620 and S630, when the network configuration status is the first status 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 status, 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 that the radio link frequently fails as described above occurs because the modulation and coding scheme scheduled by the network is large, and in order to avoid the problem, the terminal is determined to use the first target modulation scheme at this time.

Illustratively, another implementation 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 less 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 greater than the first preset value, determining that the terminal uses the first target modulation mode for information transmission.

For example, when the network configuration state is the third state, that is, when a network configuration error occurs, it may be determined whether to use the first target modulation scheme according to the coding modulation scheme, that is, when the coding modulation scheme is smaller than the first preset value, it is determined that the terminal does not use the first target modulation scheme, and when the value of the coding modulation scheme is greater than the first preset value, it is determined that the terminal uses the first target modulation scheme, so that the coding modulation scheme and the modulation scheme used by the terminal may be matched, thereby avoiding a problem that the terminal cannot start the first target modulation scheme according to the network configuration state, which may cause frequent radio link failure.

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

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 MCS is used correspondingly _L 、MCS _M 、MCS _H And (4) showing. Taking the first preset value of 20 and the second preset value of 24 as an example, the value ranges of the MCS levels can be as shown in table 2.

TABLE 2 value ranges of MCS levels

Grade	MCS _L	MCS _M	MCS _H
				Value range	MCS<＝20	20<MCS<24	MCS>＝24

With parameter 64QAM _.support For representing whether the terminal supports 64QAM and 64QAM _enable For example, for characterizing the network configuration state, the method may be based on 64QAM _.support 、64QAM _enable MCS level together to determine whether the terminal currently activates 64QAM.

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

When table 364 QAM.support is false, terminal 64QAM dynamic switching state table

Parameter(s)	64QAM _.support	64QAM _enable	MCS level	64QAM
					Value taking	false	true/false/null	MCS _L /MCS _M /MCS _H	disable

At 64QAM _.support To true, i.e., the terminal supports 64QAM, and 64QAMenable is not null, i.e., the network may determine whether the terminal uses 64QAM based on table 4 when the SIB2 message broadcasts a valid value configured by the network for 64QAM.

Table 464 QAM. support is true,64QAMenable is not null,64QAM dynamic switching status table

Parameter(s)	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

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

Table 564 QAM. supported is true,64QAMenable is null,64QAM dynamic switching status table

Parameter(s)	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 value of 64QAM is disable, it indicates that the terminal does not use 64QAM, and when the value of 64QAM is enable, it indicates that the terminal uses 64QAM.

At 64QAM _.support For example, the value of (1) is true, the value of enable64QAM is false, the value of enable _64QAM _ v1270 is true, and the value of MCS is 26, and 64QAM _.support Value of (1) is true, value of enable64QAM is false, value of enable _64QAM _ v1270 is falseFor true, then 64QAM is according to Table 1 _enable Should be null. The value of MCS is 26, the level of MCS is MCS according to Table 2 _H 。64QAM _support Has a value of true,64QAM _enable The value of (1) is null, and the level of MCS is MCS _H Then, according to table 5, at this time 64QAM should be in the enabled state, so it is determined that the terminal uses the first target modulation scheme at this time.

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, go to step S902, if no, go to step S908;

in step S902, it is determined whether or not the values of enable64QAM and enable _64QAM _ v1270 are the same, and if yes, the process proceeds to step S903, and if no, the process proceeds to step S906;

in step S903, it is determined whether both the enable64QAM and the enable _64QAM _ v1270 are true, and if not, the process goes to step S904, and if so, the process goes to step S905;

in step S904, it is determined whether or not the MCS level is MCS _H If yes, go to step S907, otherwise, go to step S908;

in step S905, it is determined whether or not the MCS level is MCS _L If not, go to step S907; if yes, go to step S908;

in step S906, it is determined whether or not the MCS level is MCS _L If yes, go to step S908, otherwise go to step S907;

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

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

In the disclosure, 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 coding modulation scheme, so that the accuracy of determining whether the terminal uses the first target modulation mode can be improved, and the problem of frequent radio link failure caused by mismatching of the modulation mode used by the terminal and the modulation coding scheme scheduled by the network is avoided, so that the terminal falls to 2G and user experience is influenced.

Meanwhile, when the network configures the effective value for the first target modulation mode, that is, when the network configuration state is the first state or the second state, the network indication is followed as much as possible. For example, taking 64QAM as an example, when the MCS is greater than 20 and less than 24, since the frequency of radio link failure is low even if the terminal does not use 64QAM, at this time, the terminal may follow the network indication, that is, in the case where the network configuration status indicates that the terminal uses the first target modulation scheme, the terminal activates the first target modulation scheme, and in the case where the network status indicates that the terminal does not use the first target modulation scheme, the terminal does not activate the first target modulation scheme. Therefore, the user internet experience is guaranteed, and the network configuration is met as much as possible.

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, the network is misconfigured, whether the terminal uses the first target modulation scheme may be indicated by the value of the MCS. That is, the present disclosure can 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 not only improves user experience, but also satisfies network configuration.
