Technical field

This application relates to the field of communication technology, and in particular to a communication method and device.

Background technique

In the pre-scheduling mechanism, the network device actively issues uplink (UL) grant information for the terminal device. Among them, the uplink authorization information includes resource allocation (resource allocation) information and modulation and coding scheme (MCS) used for data scheduling. After receiving the uplink authorization information, the terminal device encodes and modulates the service data to be transmitted according to the MCS, and transmits the encoded and modulated service data to the network device through the transmission resources indicated by the resource allocation information to reduce the data scheduling delay.

Among them, after the terminal device receives the uplink authorization information, if the terminal device does not have service data to be transmitted, the terminal device needs to send one or more padding data to the network device to fill the transmission indicated by the resource allocation information Resources, until the terminal device has service data to be transmitted.

However, the terminal device transmits the filling data multiple times, which will cause problems such as waste of air interface resources, increased power consumption of the terminal device, and uplink interference.

Summary of the invention

The embodiments of the present application provide a communication method and device, which can save air interface resources, reduce power consumption of terminal equipment, and reduce uplink interference.

In order to achieve the foregoing objectives, the following technical solutions are adopted in the embodiments of this application:

In the first aspect, an embodiment of the present application provides a communication method, and the execution subject of the method may be a network device or a chip applied to the network device. The following description will be given by taking a network device as the execution subject as an example. The method includes: a network device receives first pre-scheduled data from a terminal device. When the first pre-scheduled data includes padding data, the network device determines a first scheduling strategy, and the first scheduling strategy is used to instruct to stop scheduling the terminal device or reduce the amount of data scheduled for the terminal device. Here, "the first pre-scheduling data includes padding data" specifically refers to "the first pre-scheduling data includes padding data but does not include service data".

In the communication method provided by the embodiment of the present application, after the network device receives the first pre-scheduling data from the terminal device, in the case that the first pre-scheduling data includes padding data, the network device can determine a new first scheduling policy to stop the communication The terminal device performs scheduling or reduces the amount of data scheduled for the terminal device, thereby reducing the transmission resources of the air interface occupied by the filling data. Since the terminal device no longer sends padding data, or the amount of padding data sent is reduced, the power consumption of the terminal device is reduced, and uplink interference is reduced. In addition, the communication method provided by the embodiment of the present application still complies with the existing communication protocol, and the terminal device does not need to perform other processing steps, which reduces the difficulty of implementation.

In a possible design, the network device determining the first scheduling strategy includes: the network device determining the first scheduling strategy according to the first ratio. Wherein, the first ratio is the ratio of the first value to the second value, the first value is the number of times that the first pre-scheduled data received by the network device in the first preset time period is filled with data, and the second value is the number of times the network device is in The number of times the first pre-scheduled data is received in the first preset time period.

That is to say, when determining the first scheduling strategy, the network device also determines the corresponding first scheduling strategy in combination with the status of the first pre-scheduled data received within the first preset time period.

In a possible design, when the first ratio is greater than the first threshold and less than the second threshold, the first scheduling strategy is used to instruct to reduce the amount of data scheduled for the terminal device. At this time, the network device increases the scheduling period when scheduling the terminal device and/or reduces the amount of transmission resources when scheduling the terminal device, so as to improve resource utilization and save air interface resources. Or, when the first ratio is greater than or equal to the second threshold, the first scheduling policy is used to instruct to stop scheduling the terminal device. At this time, the network device stops allocating transmission resources to the terminal device, thereby saving air interface resources.

In a possible design, the first scheduling strategy is used to instruct to reduce the amount of data scheduled for the terminal device. The communication method in this embodiment of the application further includes: the network device receives second pre-scheduled data from the terminal device, and the second pre-scheduled data The scheduling data is transmitted according to the first scheduling strategy. The network device determines the second ratio according to the second pre-scheduling data, and then determines the second scheduling strategy according to the second ratio. Wherein, the second ratio is the ratio of the third value to the fourth value, the third value is the number of times that the second pre-scheduled data received by the network device in the second preset time period is filled with data, and the fourth value is the network device The number of second pre-scheduled data received in the second preset time period. The second scheduling strategy is a scheduling strategy for transmitting the first pre-scheduled data or the first scheduling strategy or is used to instruct to stop scheduling the terminal device.

In this way, the network device determines the corresponding second scheduling strategy based on the status of the second pre-scheduled data received within the second preset time period, so as to save air interface resources. In addition, the third threshold and the fourth threshold can be adjusted according to actual business scenarios to meet the requirements of actual business scenarios and reduce the number of invalid scheduling.

In a possible design, when the second ratio is less than or equal to the third threshold, the second scheduling strategy is a scheduling strategy for transmitting the first pre-scheduled data. At this time, the network equipment resumes normal scheduling. Or, when the second ratio is greater than the third threshold and less than the fourth threshold, the second scheduling strategy is the first scheduling strategy. At this time, the network device maintains the current scheduling period and transmission resource amount when scheduling the terminal device. Or, when the second ratio is greater than or equal to the fourth threshold, the second scheduling policy is used to instruct to stop scheduling the terminal device. At this time, the network device stops allocating transmission resources for the terminal device.

In a possible design, the communication method of the embodiment of the present application further includes: the network device records the first value and the second value, so that the network device counts the first ratio.

In a possible design, when the first scheduling strategy is used to indicate to reduce the amount of data scheduled for the terminal device, the first scheduling strategy includes increasing the scheduling period when the terminal device is scheduled and/or reducing the scheduling period for the terminal device. The amount of transmission resources during scheduling. In this way, the period for the terminal device to send filling data to the network device is increased, and/or the data volume of the filling data sent by the terminal device to the network device each time is reduced, which reduces the air interface resources occupied by the filling data, thereby to a certain extent The transmission resources of the air interface are saved, and the power consumption of the terminal equipment and the uplink interference are reduced. Alternatively, when the first scheduling policy is used to instruct to stop scheduling the terminal device, the first scheduling policy includes stopping the scheduling of the terminal device. At this time, the network device no longer needs to allocate transmission resources to the terminal device, thereby saving air interface resources.

In the embodiments of the present application, “a plurality of” includes two or more than two. In the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

First, introduce the technical terms involved in related technologies:

1. Uplink (UL) grant information

The uplink authorization information is the physical control channel information sent by the network device to the terminal device. The uplink authorization information includes resource allocation information and modulation and coding scheme (MCS) used for data scheduling. Among them, the MCS is used to indicate the modulation mode and coding efficiency of the service data, and the resource allocation information is used to indicate the transmission resources of the service data. For example, the resource allocation information is used to indicate the location of a resource block (RB). In this way, after a certain period of time (such as four transmission time intervals (TTI)) when the terminal device receives the uplink authorization information, the terminal device sends service data to the network device through the transmission resource.

2. Cache status report (buffer status report, BSR)

The BSR includes a parameter indicating the amount of data to be transmitted in the buffer of the current terminal device. The terminal device sends the BSR to the network device. After the network device receives the BSR from the terminal device, it determines the scheduling strategy according to the parameter indicating the amount of data to be transmitted in the BSR and its own status, and schedules the terminal device according to the determined scheduling strategy.

3. Scheduling request (SR)

SR is used to indicate that the terminal device has service data to be transmitted, which is transmitted from the terminal device to the network device, so that the network device allocates transmission resources for the terminal device.

4. Padding data

Filling data is used to fill transmission resources and is a kind of meaningless data. The padding data can be all zeros or all empty data, or other forms of data. If a data table includes filling data but does not include business data, the data packet is also called an empty data packet.

In the related art, in order to reduce the data scheduling delay of the wireless air interface part, the uplink data scheduling process includes the following two types:

The first is the traditional uplink data scheduling process

Referring to Figure 1, the traditional uplink data scheduling process includes the following steps:

S10. The terminal device determines that there is service data to be sent.

Exemplarily, the service data may be data of an ultra-reliable and low latency communication (URLLC) service such as automatic driving.

S11. The terminal device sends an SR to the network device. Correspondingly, the network device receives the SR from the terminal device.

Among them, SR is used to indicate that the terminal device has service data to be transmitted.

S12. The network device sends uplink authorization information to the terminal device. Correspondingly, the terminal device receives the uplink authorization information from the network device.

Among them, the uplink grant information includes RB location information and MCS.

S13. The terminal equipment encodes and modulates the service data according to the MCS, and transmits the encoded and modulated service data at the position of the RB. Correspondingly, the network device receives the coded and modulated service data from the terminal device at the position of the RB.

In this way, when the terminal device has service data to be sent, the terminal device requests the network device for transmission resources through the SR, and then transmits the service data through the transmission resources allocated by the network device. However, in the scenario of frequent discontinuous uplink service data transmission, the terminal device frequently sends SR to the network device, and the step of frequently transmitting the SR still does not reduce the data scheduling delay.

The second, the uplink data scheduling process of the pre-scheduling mechanism

Referring to Figure 2, the uplink data scheduling process of the pre-scheduling mechanism includes the following steps:

S20. The network device determines that there is service data to be sent in the terminal device.

Exemplarily, after receiving the service data from the network device, the terminal device feeds back a confirmation message to the network device. In this way, after the network device sends the service data to the terminal device, it can determine that the terminal device has service data to be sent, and then allocate transmission resources to the terminal device.

S21. The network device sends uplink authorization information to the terminal device. Correspondingly, the terminal device receives the uplink authorization information from the network device.

S22. The terminal equipment encodes and modulates the service data according to the MCS, and transmits the encoded and modulated service data at the position of the RB. Correspondingly, the network device receives the coded and modulated service data from the terminal device at the position of the RB.

In this way, for the scenario of discontinuous uplink service data frequent transmission, the network device can actively allocate transmission resources for the terminal device, reducing the transmission steps of the SR, and reducing the data scheduling delay. However, after the terminal device receives the uplink authorization information, if the terminal device does not have service data to be transmitted, the terminal device needs to send one or more padding data to the network device to fill the transmission indicated by the resource allocation information Resources, until the terminal device has service data to be transmitted. Since the terminal device transmits the filling data multiple times, problems such as waste of air interface resources, increased power consumption of the terminal device, and uplink interference are caused.

Aiming at the technical problem of "the waste of air interface resources caused by the transmission of filling data, the increase in power consumption of terminal equipment and the uplink interference", two solutions in related technologies are as follows:

In the first solution, the network device sends a blocking instruction to the terminal device to prevent the terminal device from sending padding data. Such a solution requires modification of the existing third generation partnership project (3GPP) protocol standards, and requires network equipment and terminal equipment to be implemented at the same time, which increases the difficulty of implementation.

In the second solution, the network device releases transmission resources when it determines that the terminal device has no service data. In other words, the allocation and release of transmission resources by network equipment and terminal equipment must be consistent in time. However, in actual applications, it is difficult for network devices to accurately determine whether a terminal device sends service data, and problems such as large data scheduling delays and waste of transmission resources are prone to occur. In addition, when the network device sends uplink authorization information to the terminal device, but the terminal device fails to receive the uplink authorization information from the network device, and the terminal device has service data to be transmitted, the terminal device still requests the network device through SR Transmission resources, which still increase the data scheduling delay and waste transmission resources.

In view of this, the embodiment of the present application provides a communication method, and the communication method of the embodiment of the present application is applicable to various communication systems. The communication method provided in the embodiments of the present application can be applied to a long term evolution (LTE) system, or a fifth-generation (5G) communication network, or other similar networks, or other networks in the future.

The communication systems and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art knows that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

The communication method provided by the embodiment of the present application will be described in detail below.

It should be noted that the name of the message between each network element or the name of each parameter in the message in the following embodiments of the present application is just an example, and other names may also be used in specific implementations, which are explained here in a unified manner and will not be described below. Go into details.

The embodiment of the present application provides a communication method, which is applied in the data transmission process of the pre-scheduling mechanism. Referring to Figure 4, the communication method includes the following steps:

S400: The network device sends the first uplink authorization information to the terminal device. Correspondingly, the terminal device receives the first uplink authorization information from the network device.

Wherein, the first uplink grant information includes RB location information and MCS.

Exemplarily, the network device initiates a pre-scheduling process for a certain terminal device. The network device determines whether to allocate transmission resources for the terminal device based on certain judgment conditions. When the network device determines to allocate transmission resources for the terminal device, the network device indicates the location of the RB through the uplink authorization information.

S401. The terminal device encodes and modulates the first pre-scheduled data according to the MCS in the first uplink grant information, and transmits the encoded and modulated first pre-scheduled data at the position of the RB indicated by the first uplink grant information. data. Correspondingly, the network device receives the encoded and modulated first pre-scheduling data from the terminal device at the position of the RB indicated by the first uplink grant information.

Wherein, the first pre-scheduling data includes service data and/or filling data. The value of each bit in the business data is determined according to the actual business conditions. Each bit in the padding data can be all zeros or all empty.

Here, after the terminal device receives the first uplink authorization information, if the terminal device has service data to be transmitted, the first pre-scheduled data includes service data but not padding data, or the first pre-scheduled data includes service data And fill in the data. If there is no service data to be transmitted in the terminal device, the first pre-scheduled data includes padding data, but does not include service data.

Correspondingly, after the network device receives the first pre-scheduled data, the network device performs a validity check on the received first pre-scheduled data, such as identifying characteristics of the first pre-scheduled data to determine the value of the first pre-scheduled data. The specific situation. Among them, the specific conditions of the first pre-scheduling data can be divided into the following three types: the first pre-scheduling data includes service data but does not include padding data, or the first pre-scheduling data includes service data and padding data, or the first pre-scheduling data includes service data and padding data. The data includes padding data, but does not include business data.

In the case where the first pre-scheduling data includes service data but does not include filling data, or the first pre-scheduling data includes service data and filling data, the network device determines that the pre-scheduling process performed on the terminal device this time is normal scheduling. At this time, the network device still schedules the terminal device according to the current scheduling strategy, or, in the case that the first pre-scheduled data includes the BSR, the network device determines the corresponding scheduling strategy based on the BSR, such as when determining to schedule the terminal device The scheduling period and the amount of transmission resources. The network device performs normal processing on the first pre-scheduled data received this time.

In the case where the first pre-scheduling data includes filling data but does not include service data, the network device determines that the pre-scheduling process performed on the terminal device this time is invalid scheduling. The network device discards the first pre-scheduled data received this time. In order to reduce the number of invalid scheduling and save air interface resources, the network device executes S402:

S402: When the first pre-scheduling data includes padding data, the network device determines a first scheduling strategy.

Wherein, "the first pre-scheduling data includes padding data" means "the first pre-scheduling data is padding data", and can also be expressed as "the first pre-scheduling data includes padding data and does not include service data". "The first pre-scheduled data includes padding data" does not include the case that "the first pre-scheduled data includes service data and padding data".

The first scheduling strategy is used to instruct to stop scheduling the terminal device or reduce the amount of data scheduled for the terminal device.

When the first scheduling policy is used to instruct to stop scheduling the terminal device, the first scheduling policy includes stopping the scheduling of the terminal device. Exemplarily, the network device no longer sends the second uplink authorization information to the terminal device. Correspondingly, the terminal device no longer receives the second uplink authorization information from the network device, that is, the terminal device does not obtain the transmission resource allocated by the network device, and therefore no longer sends the padding data, thereby saving the transmission resources of the air interface part. , To reduce the power consumption of terminal equipment and uplink interference.

When the first scheduling strategy is used to indicate to reduce the amount of data scheduled for the terminal device, the first scheduling strategy includes increasing the scheduling period when scheduling the terminal device and/or reducing the amount of transmission resources when scheduling the terminal device. Here, the scheduling period may refer to the period for transmitting the second uplink grant information, and the amount of transmission resources may refer to the resource amount of the transmission resources indicated by the resource allocation information in the second uplink grant information. In this way, the specific implementation of the first scheduling strategy can be, for example, but not limited to the following three examples:

Example 1: The period for the network device to send the second uplink authorization information to the terminal device is increased. Correspondingly, the period for the terminal device to receive the second uplink authorization information from the network device is also increased. However, the amount of transmission resources allocated by the second uplink grant information remains unchanged. That is, the period for transmitting the second uplink grant information is greater than the period for transmitting the first uplink grant information, and the amount of transmission resources indicated by the second uplink grant information is equal to that indicated by the first uplink grant information The amount of transmission resources. In this way, although the data volume of the padding data sent by the terminal device to the network device each time has not changed, the period of the padding data sent by the terminal device to the network device is increased, which reduces the air interface resources occupied by the padding data. To a certain extent, the transmission resources of the air interface are saved, and the power consumption and uplink interference of the terminal equipment are reduced.

Example 2: The period for the network device to send the second uplink authorization information to the terminal device remains unchanged. Correspondingly, the period for the terminal device to receive the second uplink grant information from the network device also remains unchanged. However, the amount of transmission resources allocated by the second uplink grant information is reduced. That is, the period of transmitting the second uplink grant information is equal to the period of transmitting the first uplink grant information, and the amount of transmission resources indicated by the second uplink grant information is less than that indicated by the first uplink grant information The amount of transmission resources. In this way, although the period for the terminal device to send the filling data to the network device has not changed, the data volume of the filling data sent by the terminal device to the network device each time is reduced, which reduces the air interface resources occupied by the filling data, thereby to a certain extent The transmission resources of the air interface are saved, and the power consumption of the terminal equipment and the uplink interference are reduced.

Example 3: The period for the network device to send the second uplink authorization information to the terminal device is increased. Correspondingly, the period for the terminal device to receive the second uplink authorization information from the network device is also increased. In addition, the amount of transmission resources allocated by the second uplink grant information is reduced. That is, the period for transmitting the second uplink grant information is greater than the period for transmitting the first uplink grant information, and the amount of transmission resources indicated by the second uplink grant information is less than that indicated by the first uplink grant information The amount of transmission resources. In this way, the period for the terminal device to send filling data to the network device is increased, and the amount of filling data sent by the terminal device to the network device each time is reduced, which reduces the air interface resources occupied by the filling data, thereby saving air interface transmission resources. , Which reduces the power consumption of terminal equipment and uplink interference.

It should be noted that the scheduling period of the network equipment to the terminal equipment increases, and accordingly, the scheduling frequency of the network equipment to the terminal equipment decreases. In other words, "increase the scheduling period when scheduling the terminal device" can also be replaced with "decrease the scheduling frequency when scheduling the terminal device". Correspondingly, "the period for the network device to send the second uplink authorization information to the terminal device is increased" can also be replaced with "the frequency for the network device to send the second uplink authorization information to the terminal device is reduced". "The period for terminal equipment to send padding data to network equipment increases" can also be replaced with "the frequency of terminal equipment to send padding data to network equipment decreases."

In the communication method provided by the embodiment of the present application, after the network device receives the first pre-scheduling data from the terminal device, in the case where it is determined that the first pre-scheduling data includes padding data, the network device can determine a new scheduling strategy, that is, the first scheduling Strategies to stop scheduling terminal equipment or reduce the amount of data scheduled for terminal equipment. Since the network device no longer schedules the terminal device, or the amount of data scheduled for the terminal device is reduced, air interface resources are saved. Since the terminal device no longer sends padding data, or the amount of padding data sent is reduced, the power consumption of the terminal device and the uplink interference problem are reduced. In addition, the communication method provided by the embodiment of the present application still complies with the existing communication protocol, and the terminal device does not need to perform other processing steps, which reduces the difficulty of implementation.

In some embodiments, the network device also determines the corresponding first scheduling strategy based on the status of the first pre-scheduled data received within the first preset time period. Referring to Figure 5, S402 can be specifically implemented as the following steps:

S4021. When the first pre-scheduled data includes padding data, the network device determines the first scheduling strategy according to the first ratio.

Wherein, the first ratio is the ratio of the first value to the second value, the first value is the number of times that the first pre-scheduled data received by the network device in the first preset time period is filled with data, and the second value is the number of times the network device is in The number of times the first pre-scheduled data is received in the first preset time period. The first preset time period may be a time period in which the current time point is the starting time point, and the time length is the preset time length (for example, 10 milliseconds). The current scheduling period can be 1 millisecond.

Exemplarily, the network device is pre-configured with two thresholds, that is, the first threshold and the second threshold. Wherein, the first threshold and the second threshold may be any value between 0% and 100%. The first threshold is less than the second threshold. The value of the first threshold may be 0%, and the value of the second threshold may be 100%.

When the first ratio is greater than the first threshold and less than the second threshold, the network device determines that the first scheduling policy is used to instruct to reduce the amount of data scheduled for the terminal device. That is to say, in the first preset time period, the probability that the network device receives an empty data packet (the first pre-scheduled data in the empty data packet includes padding data but does not include service data) is greater than the first threshold and less than the first Two thresholds. At this time, the network device determines to reduce the amount of data scheduled for the terminal device, that is, increase the scheduling period when scheduling the terminal device and/or reduce the amount of transmission resources when scheduling the terminal device, so as to improve the utilization of transmission resources, Save air interface resources.

When the first ratio is greater than the second threshold, the network device determines that the first scheduling policy is used to instruct to stop scheduling the terminal device. That is, in the first preset time period, the probability that the network device receives a null data packet is greater than the second threshold. At this time, even if the network device allocates transmission resources to the terminal device again, the probability that the first pre-scheduled data sent by the terminal device through the re-allocated transmission resource is filling data is relatively high. In this way, the network device determines to stop scheduling the terminal device. There is no need to allocate transmission resources for terminal devices, thereby saving air interface resources.

It should be noted that when the first ratio is less than the first threshold, the network device determines that the first scheduling strategy is the current scheduling strategy, that is, the scheduling strategy for transmitting the first pre-scheduled data. In other words, the scheduling period and the amount of transmission resources when the network device schedules the terminal device remain unchanged. In addition, it is easy to understand that the first scheduling strategy corresponding to "the first ratio is equal to the first threshold" and "the first ratio is equal to the second threshold" can be divided into the following three situations:

Case 1: When the first ratio is equal to the first threshold, the network device determines that the first scheduling strategy is the current scheduling strategy for transmitting the first pre-scheduled data. When the first ratio is equal to the second threshold, the network device determines that the first scheduling policy is used to instruct to reduce the amount of data scheduled for the terminal device.

Case 2: When the first ratio is equal to the first threshold, the network device determines that the first scheduling strategy is the current scheduling strategy for transmitting the first pre-scheduled data. When the first ratio is equal to the second threshold, the network device determines that the first scheduling policy is used to instruct to stop scheduling the terminal device.

Case 3: When the first ratio is equal to the first threshold, the network device determines that the first scheduling policy is used to instruct to reduce the amount of data scheduled for the terminal device. When the first ratio is equal to the second threshold, the network device determines that the first scheduling policy is used to instruct to stop scheduling the terminal device.

In this way, when the network device determines that the first pre-scheduled data is filling data, the network device determines the corresponding first scheduling strategy based on the probability of the received empty data packet within the first preset time period. The probability of the received empty data packet is When it is low, the first scheduling strategy determined by the network device is to reduce the amount of data for scheduling the terminal device. When the probability of the received empty data packet is high, the network device stops scheduling the terminal device to save air interface resources. In addition, the first threshold and the second threshold can be adjusted according to actual business scenarios to meet the requirements of actual business scenarios and reduce the number of invalid scheduling.

In addition, in order to facilitate the network device to count the probability of receiving an empty data packet (that is, the first pre-scheduled data in the data packet includes padding data but not service data) within the first preset time period, refer to Figure 6, where the network device receives In the case of the first pre-scheduled data from the terminal device, the network device executes S403. When the network device determines that the first pre-scheduled data includes filling data but does not include service data, the network device executes S404. Among them, the specific descriptions of S403 and S404 are as follows:

S403. The network device records the second value.

For the second value, please refer to the relevant description of S4021, which will not be repeated here.

Exemplarily, after the network device receives the first pre-scheduled data, the network device updates the second value. In addition, the network device stores the corresponding relationship between the identification of the terminal device and the second value to indicate that the second value is the number of times the network device receives the first pre-scheduled data from the terminal device within the first preset time period .

S404: When the first pre-scheduled data is filling data, the network device records the first value.

For the first value, please refer to the relevant description of S4021, which will not be repeated here.

Exemplarily, after the network device receives the first pre-scheduled data, the network device further checks the validity of the first pre-scheduled data, and when it is determined that the first pre-scheduled data includes padding data but does not include service data, the network device updates The first value, and the network device stores the corresponding relationship between the identification of the terminal device and the first value to indicate that the first value is the first preset value received by the network device from the terminal device within the first preset time period. The scheduling data is the number of filling data.

It should be noted that the network device may execute S403 first, and then execute S404. The network device may also execute S404 first, and then execute S403. The network device can also execute S403 and S404 at the same time. The embodiment of the present application does not limit the execution sequence of S403 and S404.

In this way, the network device updates the first value and the second value in real time, so that the network device can count the probability of receiving an empty data packet within the first preset time period.

It should be noted that if the counting method adopted by the network device is as follows: every time the first pre-scheduled data is determined to be filling data, the first value is increased by one on the original basis, and each time the first pre-scheduled data is received, the The second value is increased by one on the original basis, and the first value and the second value are deleted once every time the network device is separated by the first preset time period, so that the first value can be counted again in the next first preset time period And the second value, so that the network device accurately counts the probability of receiving a null data packet within the first preset time period. In addition, the network device may also use the following counting method: each time the first pre-scheduled data is determined to be filling data, the corresponding first time is recorded, and the number of the first time within the first preset time period is taken as the first value; Each time the first pre-scheduled data is received, the corresponding second time is recorded, and the number of the second time within the first preset time period is taken as the second value.

In some embodiments, when the first scheduling policy is used to instruct to reduce the amount of data scheduled for the terminal device, referring to FIG. 7, the communication method according to the embodiment of the present application further includes the following steps:

S405: The network device sends the second uplink authorization information to the terminal device. Correspondingly, the terminal device receives the second uplink authorization information from the network device.

Wherein, the amount of transmission resources indicated by the second uplink grant information and/or the transmission period of the second uplink grant information are determined by the first scheduling strategy.

S406. The terminal device encodes and modulates the second pre-scheduled data according to the MCS in the second uplink grant information, and transmits the encoded and modulated second pre-scheduled data at the position of the RB indicated by the second uplink grant information. data. Correspondingly, the network device receives the encoded and modulated second pre-scheduling data from the terminal device at the position of the RB indicated by the second uplink grant information.

Wherein, the second pre-scheduling data includes service data and/or filling data.

Here, after the terminal device receives the second uplink authorization information, if the terminal device has service data to be transmitted, the second pre-scheduled data includes service data but not padding data, or the second pre-scheduled data includes service data And fill in the data. If there is no service data to be transmitted in the terminal device, the second pre-scheduling data includes padding data but does not include service data.

Correspondingly, after the network device receives the second pre-scheduled data, the network device still checks the validity of the received second pre-scheduled data.

S407: The network device determines a second ratio according to the second pre-scheduling data.

Wherein, the second ratio is the ratio of the third value to the fourth value, the third value is the number of times that the second pre-scheduled data received by the network device in the second preset time period is filled with data, and the fourth value is the network device The number of second pre-scheduled data received in the second preset time period. The duration of the second preset time period may be the same as the duration of the first preset time period, or may be different from the duration of the first preset time period.

Exemplarily, when the network device receives the second pre-scheduled data, the network device updates the fourth value, that is, the number of times the network device receives the second pre-scheduled data within the second preset time period plus one. After the network device checks the validity of the second pre-scheduled data, if the second pre-scheduled data includes filling data but does not include service data, the network device updates the third value, that is, the network device receives the data within the second preset time period. The second pre-scheduled data is the number of filling data plus one.

S408: The network device determines a second scheduling strategy according to the second ratio.

Exemplarily, the network device presets the third threshold and the fourth threshold. Wherein, the third threshold is less than the fourth threshold. The third threshold may be the same as or different from the first threshold. The fourth threshold may be the same as or different from the second threshold.

When the second ratio is less than the third threshold, the network device determines that the second scheduling strategy is a scheduling strategy for transmitting the first pre-scheduled data. At this time, the network equipment resumes normal scheduling. When the first ratio is greater than the third threshold and less than the fourth threshold, the network device determines that the second scheduling strategy is the first scheduling strategy, that is, the scheduling strategy for transmitting the second pre-scheduled data. At this time, the network device maintains the current scheduling period and the amount of transmission resources. When the first ratio is greater than the fourth threshold, the network device determines that the second scheduling policy is used to instruct to stop scheduling the terminal device. At this time, the network device stops allocating transmission resources for the terminal device.

It should be noted that the scheduling strategies corresponding to "the second ratio is equal to the third threshold" and "the second ratio is equal to the fourth threshold" can be divided into the following three situations:

Case 1: When the second ratio is equal to the third threshold, the network device determines that the second scheduling strategy is a scheduling strategy for transmitting the first pre-scheduled data. When the second ratio is equal to the fourth threshold, the network device determines that the second scheduling strategy is the first scheduling strategy, that is, the scheduling strategy for transmitting the second pre-scheduled data.

Case 2: When the second ratio is equal to the third threshold, the network device determines that the second scheduling strategy is a scheduling strategy for transmitting the first pre-scheduled data. When the second ratio is equal to the fourth threshold, the network device determines that the second scheduling policy is used to instruct to stop scheduling the terminal device.

Case 3: When the second ratio is equal to the third threshold, the network device determines that the second scheduling strategy is the first scheduling strategy, that is, the scheduling strategy for transmitting the second pre-scheduled data. When the second ratio is equal to the fourth threshold, the network device determines that the second scheduling policy is used to instruct to stop scheduling the terminal device.

In this way, the network device determines the corresponding second scheduling strategy based on the status of the second pre-scheduled data received within the second preset time period (such as the probability of an empty data packet), so as to save air interface resources. In addition, the third threshold and the fourth threshold can be adjusted according to actual business scenarios to meet the requirements of actual business scenarios and reduce the number of invalid scheduling.

In addition, in order to facilitate the network device to calculate the probability of receiving an empty data packet (that is, the second pre-scheduled data in the data packet includes padding data but not service data) within the second preset time period, see FIG. In the case of the second pre-scheduled data from the terminal device, the network device executes S409. When the network device determines that the second pre-scheduled data includes filling data but does not include service data, the network device executes S410. Among them, the specific descriptions of S409 and S410 are as follows:

S409. The network device records the fourth value.

Among them, the fourth value can refer to the relevant description of S407, which will not be repeated here.

Exemplarily, after the network device receives the second pre-scheduled data, the network device updates the fourth value. In addition, the network device stores the corresponding relationship between the identification of the terminal device and the fourth value to indicate that the fourth value is the number of times the network device receives second pre-scheduled data from the terminal device within the second preset time period .

S410: When the second pre-scheduled data is filling data, the network device records the third value.

Among them, the third value can refer to the relevant description of S407, which will not be repeated here.

Exemplarily, after the network device receives the second pre-scheduled data, the network device further checks the validity of the second pre-scheduled data. When it is determined that the second pre-scheduled data is filling data and does not include service data, the network device updates The third value. In addition, the network device stores the corresponding relationship between the terminal device's identification and the third value to indicate that the third value is the second pre-scheduled data from the terminal device received by the network device within the second preset time period. The number of data.

In this way, the network device updates the third value and the fourth value in real time, so that the network device can count the probability of receiving an empty data packet within the second preset time period.

In addition, the network device can also delete the third value and the fourth value outside the second preset time period in time, so that the network device accurately counts the probability of receiving an empty data packet within the second preset time period.

In some embodiments, the network device also determines the corresponding scheduling strategy according to the status of the first pre-scheduled data. S402 can also be implemented specifically: when the first pre-scheduling data includes padding data but does not include service data, the network device determines a scheduling policy to instruct to stop scheduling the terminal device. When the first pre-scheduling data includes service data, or includes filling data and service data, the network device determines that the scheduling strategy is the current scheduling strategy, that is, the scheduling strategy for transmitting the first pre-scheduling data.

In this way, the network device determines the corresponding scheduling strategy according to the current first pre-scheduling data, which can save air interface resources, reduce the number of invalid scheduling, and reduce implementation complexity.
