Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

In the pre-scheduling mechanism, the network device actively issues Uplink (UL) grant (grant) information for the terminal device. The uplink grant information includes resource allocation (resource allocation) information and Modulation and Coding Scheme (MCS) 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 resource indicated by the resource allocation information, so as to reduce the data scheduling delay.

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

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

Disclosure of Invention

The embodiment of the application provides 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 above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, an execution subject of the method may be a network device, or a chip applied to the network device. The following description will be given taking as an example that the execution subject is a network device. The method comprises the following steps: the network device receives first pre-scheduled data from the terminal device. When the first pre-scheduling data includes padding data, the network device determines a first scheduling policy, where the first scheduling policy is used to instruct to stop scheduling the terminal device or reduce data volume for scheduling the terminal device. Here, the "first prescheduled data includes padding data" specifically means "the first prescheduled data includes padding data and does not include traffic data".

In the communication method provided in the embodiment of the present application, after receiving the first pre-scheduling data from the terminal device, the network device may determine a new first scheduling policy when the first pre-scheduling data includes padding data, so as to stop scheduling the terminal device or reduce the data amount for scheduling the terminal device, thereby reducing transmission resources of an air interface portion occupied by the padding data. Because the terminal device does not send the padding data any more, or the data volume of the sent padding data is reduced, the power consumption of the terminal device is reduced, and the uplink interference is reduced. In addition, the communication method provided by the embodiment of the application still conforms to the existing communication protocol, and the terminal device does not need to execute other processing steps, so that the implementation difficulty is reduced.

In one possible design, the network device determines a first scheduling policy, including: and the network equipment determines a first scheduling strategy according to the first ratio. The first ratio is a ratio of a first value to a second value, the first value is the number of times that the first pre-scheduling data received by the network device in the first preset time period is padding data, and the second value is the number of times that the first pre-scheduling data received by the network device in the first preset time period is padding data.

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

In one possible design, when the first ratio is greater than the first threshold and less than the second threshold, the first scheduling policy 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 the terminal device is scheduled and/or reduces the amount of transmission resources when the terminal device is scheduled, so as to improve the resource utilization rate and save the air interface resources. Or when the first ratio is greater than or equal to the second threshold, the first scheduling policy is used for indicating that the terminal equipment is stopped to be scheduled. At this time, the network device stops allocating transmission resources to the terminal device, thereby saving air interface resources.

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

In this way, the network device determines a corresponding second scheduling policy according to a status of second pre-scheduling data received within a second preset time period, so as to save air interface resources. And the third threshold and the fourth threshold can be adjusted according to the actual service scene to meet the requirement of the actual service scene and reduce the times of invalid scheduling.

In one possible design, when the second ratio is less than or equal to the third threshold, the second scheduling policy is a scheduling policy for transmitting the first pre-scheduled data. At this point, the network device resumes normal scheduling. Or when the second ratio is greater than the third threshold and smaller than the fourth threshold, the second scheduling policy is the first scheduling policy. At this time, the network device maintains the scheduling period and the amount of transmission resources when the terminal device is currently scheduled. 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 point, the network device stops allocating transmission resources for the terminal device.

In one possible design, the communication method according to the embodiment of the present application further includes: the network device records the first value and the second value so that the network device can count the first ratio.

In one possible design, when the first scheduling policy is used to indicate a reduction in the amount of data to schedule the terminal device, the first scheduling policy includes increasing a scheduling period when the terminal device is scheduled and/or reducing an amount of transmission resources when the terminal device is scheduled. Therefore, the period of sending the filling data to the network equipment by the terminal equipment is increased, and/or the data volume of the filling data sent to the network equipment by the terminal equipment each time is reduced, so that the empty resource occupied by the filling data is reduced, the transmission resource of the empty part is saved to a certain extent, and the power consumption and the uplink interference of the terminal equipment are reduced. Or when the first scheduling policy is used to instruct to stop scheduling the terminal device, the first scheduling policy includes stopping scheduling the terminal device. At this time, the network device does not need to allocate transmission resources to the terminal device, thereby saving air interface resources.

Detailed Description

The terms "first" and "second" and the like in the description and drawings of the present application are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of the objects. Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. In the embodiments of the present application, "a plurality" includes two or more. In the embodiments of the present application, the words "exemplary" or "such as" are used herein to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion.

First, technical terms involved in the related art are introduced:

1. uplink (UL) grant (grant) information

The uplink grant information is physical control channel information sent by the network device to the terminal device. The uplink grant information includes resource allocation (resource allocation) information for data scheduling and Modulation and Coding Scheme (MCS). The MCS is used to indicate a modulation scheme and coding efficiency of the service data, and the resource allocation information is used to indicate transmission resources of the service data, for example, the resource allocation information is used to indicate a location of a Resource Block (RB). In this way, after the terminal device receives a certain time duration (e.g., four Transmission Time Intervals (TTIs)) of the uplink grant information, the terminal device transmits the traffic data to the network device through the transmission resource.

2. 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 a BSR to the network device. After receiving the BSR from the terminal equipment, the network equipment determines a scheduling strategy according to the parameters indicating the data volume to be transmitted in the BSR and the self condition, and schedules the terminal equipment according to the determined scheduling strategy.

3. Scheduling Request (SR)

The SR is used to indicate service data to be transmitted by the terminal device, and the terminal device transmits the service data to the network device, so that the network device allocates transmission resources for the terminal device.

4. Padding data

Padding data is used to fill the transmission resource and is meaningless data. The padding data may be all zero or all null data, or other forms of data. If a certain data table includes padding data but no traffic data, the data packet is also called a null data packet.

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

first, the conventional uplink data scheduling procedure

Referring to fig. 1, a conventional uplink data scheduling process includes the following steps:

s10, the terminal equipment determines that the service data to be sent exist.

For example, the service data may be data of a low-latency and high-reliability communication (URLLC) service such as an automatic driving service.

S11, the terminal equipment sends the SR to the network equipment. Accordingly, the network device receives the SR from the terminal device.

The SR is used for indicating that the terminal equipment has service data to be transmitted.

S12, the network equipment sends uplink authorization information to the terminal equipment. Accordingly, the terminal device receives uplink grant information from the network device.

Wherein the uplink grant information includes position information of the RB and the MCS.

And 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. Accordingly, the network device receives the coded and modulated service data from the terminal device at the position of the RB.

Thus, 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 a discontinuous uplink service data frequent scenario, the terminal device frequently sends an SR to the network device, and the step of frequently transmitting the SR still does not reduce the data scheduling delay.

Second, uplink data scheduling procedure of pre-scheduling mechanism

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

s20, the network equipment determines that the terminal equipment has service data to be sent.

Illustratively, after receiving the service data from the network device, the terminal device feeds back an acknowledgement message to the network device. Therefore, after the network device sends the service data to the terminal device, the terminal device can be determined to have the service data to be sent, and then transmission resources are allocated to the terminal device.

S21, the network equipment sends uplink authorization information to the terminal equipment. Accordingly, the terminal device receives uplink grant 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. Accordingly, the network device receives the coded and modulated service data from the terminal device at the position of the RB.

Therefore, for a discontinuous uplink service data frequency transmission scene, the network device can actively allocate transmission resources to the terminal device, and reduce the transmission steps of the SR, so as to reduce the data scheduling delay. However, after the terminal device receives the uplink grant information, if the terminal device does not have the service data to be transmitted, the terminal device needs to send padding (padding) data to the network device one or more times to fill the transmission resource indicated by the resource allocation information until the terminal device has the service data to be transmitted. The problems of air interface resource waste, power consumption increase of the terminal equipment, uplink interference and the like are caused by the fact that the terminal equipment transmits the filling data for many times.

For the technical problems of air interface resource waste, power consumption increase of terminal equipment and uplink interference caused by transmission of padding data, two solutions in the related art are as follows:

in a first solution, the network device sends a blocking instruction to the terminal device to block the terminal device from sending filler data. The solution needs to modify the existing third generation partnership project (3 GPP) protocol standard, and needs to implement the network device and the terminal device at the same time, which increases the difficulty of implementation.

In a second solution, the network device releases the transmission resources when it determines that the terminal device has no traffic data. That is, the allocation and release of transmission resources by the network device and the terminal device are consistent in time. However, in the practical application process, it is difficult for the network device to accurately determine whether the terminal device sends the service data, and problems such as a long data scheduling delay and a waste of transmission resources are easily caused. In addition, the network device sends the uplink grant information to the terminal device, but the terminal device does not successfully receive the uplink grant information from the network device, and when the terminal device has service data to be transmitted, the terminal device still requests the network device for transmission resources through the SR, which still increases data scheduling delay and wastes transmission resources.

In view of this, an embodiment of the present application provides a communication method, which is applicable to various communication systems. The communication method provided by the embodiment of the 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. Fig. 3 is a schematic architecture diagram of a communication system applicable to the communication method according to the embodiment of the present application, and the communication system may include a terminal device 30 and a network device 31. Wherein, the terminal device 30 is wirelessly connected with the network device 31. The terminal device 30 may be one or more, and the network device 31 may be one or more. Only one network device and two terminal devices are shown in fig. 3. Fig. 3 is a schematic diagram only, and does not constitute a limitation to an applicable scenario of the communication method according to the embodiment of the present application.

The terminal device 30, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice/data connectivity to a user, for example, a handheld device or a vehicle-mounted device with a wireless connection function. The terminal device may specifically be: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a terminal in a future 5G communication network or a communication network after 5G, and the like, which are not limited in this embodiment.

The network device 31 is a device in a wireless communication network, for example, a Radio Access Network (RAN) node that accesses the terminal device 30 to the wireless communication network. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (WiFi) Access Point (AP), or a network side device in a future 5G communication network or a communication network after 5G, etc.

The communication system and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. As can be known to those skilled in the art, with the evolution of network architecture and the emergence of new service scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The following specifically explains the communication method provided in the embodiment of the present application.

It should be noted that, in the following embodiments of the present application, the names of messages between network elements or the names of parameters in messages, etc. are only examples, and other names may also be used in specific implementations, which are described in a unified manner herein and will not be described again below.

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

s400, the network equipment sends first uplink authorization information to the terminal equipment. Accordingly, the terminal device receives the first uplink grant information from the network device.

Wherein the first uplink grant information includes position information of the RB and the MCS.

Illustratively, the network device initiates a prescheduling procedure for a certain terminal device. The network device determines whether to allocate transmission resources to the terminal device based on a certain judgment condition. In the case where the network device determines to allocate transmission resources for the terminal device, the network device indicates the location of the RB through the uplink grant information.

S401, the terminal equipment encodes and modulates the first pre-scheduling data according to the MCS in the first uplink authorization information, and transmits the encoded and modulated first pre-scheduling data at the position of the RB indicated by the first uplink authorization information. Accordingly, 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-scheduled data comprises traffic data and/or padding data. The value of each bit in the service data is determined according to the actual service condition. The individual bits in the padding data may be all zeros or all nulls.

Here, after the terminal device receives the first uplink grant information, if the terminal device has service data to be transmitted, the first pre-scheduled data includes the service data but does not include padding data, or the first pre-scheduled data includes the service data and the padding data. If the terminal device does not have the service data to be transmitted, the first pre-scheduling data comprises the filling data and does not comprise the service data.

Correspondingly, after the network device receives the first pre-scheduling data, the network device performs validity detection on the received first pre-scheduling data, for example, performs feature recognition on the first pre-scheduling data to determine a specific condition of the first pre-scheduling data. The specific conditions of the first pre-scheduled data can be divided into the following three types: the first pre-scheduled data includes traffic data but no padding data, or the first pre-scheduled data includes traffic data and padding data, or the first pre-scheduled data includes padding data but no traffic data.

And when the first pre-scheduling data comprises the service data but does not comprise the filling data, or the first pre-scheduling data comprises the service data and the filling data, the network equipment determines that the pre-scheduling process performed on the terminal equipment at this time is normal scheduling. At this time, the network device still schedules the terminal device according to the current scheduling policy, or, in the case that the first pre-scheduling data includes a BSR, the network device determines a corresponding scheduling policy based on the BSR, such as determining a scheduling period and a transmission resource amount when the terminal device is scheduled. And the network equipment normally processes the received first pre-scheduling data.

In the case that the first pre-scheduling data includes padding data but does not include traffic data, the network device determines that the pre-scheduling process performed on the terminal device this time is invalid scheduling. And the network equipment discards the received first pre-scheduling data. In order to reduce the number of times of invalid scheduling and save air interface resources, the network device performs S402:

s402, when the first pre-scheduling data comprises filling data, the network equipment determines a first scheduling strategy.

The "first prescheduled data includes padding data" means "the first prescheduled data is padding data", and may also be expressed as "the first prescheduled data includes padding data and does not include traffic data". The "first pre-scheduled data includes padding data" does not include the case that the first pre-scheduled data includes traffic data and padding data ".

The first scheduling policy is used for indicating that the terminal equipment is stopped being scheduled or the data volume for scheduling the terminal equipment is reduced.

When the first scheduling policy is used for indicating to stop scheduling the terminal device, the first scheduling policy includes stopping scheduling the terminal device. Illustratively, the network device does not send the second uplink grant information to the terminal device any more. Accordingly, the terminal device does not receive the second uplink grant information from the network device, that is, the terminal device does not acquire the transmission resource allocated by the network device, and does not send the padding data, thereby saving the transmission resource of the air interface portion, and reducing the power consumption and uplink interference of the terminal device.

When the first scheduling policy is used to indicate to reduce the data amount for scheduling the terminal device, the first scheduling policy includes increasing a scheduling period when the terminal device is scheduled and/or reducing the amount of transmission resources when the terminal device is scheduled. Here, the scheduling period may refer to a period in which the second uplink grant information is transmitted, and the amount of transmission resources may refer to an amount of resources of transmission resources indicated by resource allocation information in the second uplink grant information. As such, the specific implementation manner of the first scheduling policy may be, for example and without limitation, the following three examples:

in an example, the period for the network device to send the second uplink grant information to the terminal device is increased. Accordingly, the period for the terminal device to receive the second uplink grant information from the network device is also increased. But 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 the amount of transmission resources indicated by the first uplink grant information. Therefore, although the data amount of the filling data sent to the network device by the terminal device each time does not change, the period of the filling data sent to the network device by the terminal device is increased, and the empty resource occupied by the filling data is reduced, so that the transmission resource of the empty part is saved to a certain extent, and the power consumption and uplink interference of the terminal device are reduced.

In example two, the period for the network device to send the second uplink grant information to the terminal device remains unchanged. Accordingly, the period of the terminal device receiving the second uplink grant information from the network device is also maintained. But the amount of transmission resources allocated by the second uplink grant information decreases. 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 smaller than the amount of transmission resources indicated by the first uplink grant information. Therefore, although the period of sending the filling data to the network device by the terminal device is not changed, the data volume of the filling data sent to the network device by the terminal device each time is reduced, and the empty resource occupied by the filling data is reduced, so that the transmission resource of the empty part is saved to a certain extent, and the power consumption and the uplink interference of the terminal device are reduced.

In example three, the period for the network device to send the second uplink grant information to the terminal device is increased. Accordingly, the period for the terminal device to receive the second uplink grant information from the network device is also increased. And, the amount of transmission resources allocated by the second uplink grant information decreases. 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 the amount of transmission resources indicated by the first uplink grant information. Therefore, the period of sending the filling data to the network equipment by the terminal equipment is increased, and the data volume of the filling data sent to the network equipment by the terminal equipment each time is reduced, so that the air interface resource occupied by the filling data is reduced, the transmission resource of the air interface part is saved, and the power consumption and the uplink interference of the terminal equipment are reduced.

It should be noted that, the scheduling period of the network device to the terminal device is increased, and correspondingly, the scheduling frequency of the network device to the terminal device is reduced. That is, the "increase of the scheduling cycle when scheduling the terminal device" may be replaced with the "decrease of the scheduling frequency when scheduling the terminal device". Accordingly, "the period for the network device to transmit the second uplink grant information to the terminal device is increased," or "the frequency for the network device to transmit the second uplink grant information to the terminal device is decreased. The "period of sending the padding data to the network device by the terminal device is increased", or "frequency of sending the padding data to the network device by the terminal device is reduced".

In the communication method provided in the embodiment of the present application, after the network device receives the first pre-scheduling data from the terminal device, the network device may determine a new scheduling policy, that is, the first scheduling policy, in a case that it is determined that the first pre-scheduling data includes padding data, so as to stop scheduling the terminal device or reduce data amount for scheduling the terminal device. Because the network equipment does not schedule the terminal equipment any more or the data amount scheduled by the terminal equipment is reduced, the air interface resource is saved. The power consumption and uplink interference of the terminal equipment are reduced because the terminal equipment does not send the filling data any more or the data volume of the sent filling data is reduced. In addition, the communication method provided by the embodiment of the application still complies with the existing communication protocol, and the terminal equipment does not need to execute other processing steps, so that the realization difficulty is reduced.

In some embodiments, the network device further determines a corresponding first scheduling policy in conjunction with a condition of the first pre-scheduled data received within the first preset time period. Referring to fig. 5, S402 may be implemented as the following steps:

s4021, when the first pre-scheduling data comprises padding data, the network device determines a first scheduling policy according to the first ratio.

The first ratio is a ratio of a first value to a second value, the first value is the number of times that the first pre-scheduling data received by the network device in the first preset time period is padding data, and the second value is the number of times that the first pre-scheduling data received by the network device in the first preset time period is padding data. The first preset time period may be a time period with the current time point as the starting time point and the duration of the time period being a preset duration (e.g., 10 ms). The current scheduling period may be 1 millisecond.

Illustratively, the network device is preconfigured with two thresholds, a first threshold and a 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%.

And when the first ratio is larger than the first threshold and smaller than the second threshold, the network equipment determines that the first scheduling strategy is used for indicating to reduce the data volume for scheduling the terminal equipment. That is, within the first preset time period, the probability that the network device receives the null data packet (the first prescheduled data in the null data packet includes the padding data and does not include the traffic data) is greater than the first threshold and less than the second threshold. At this time, the network device determines to reduce the data amount for scheduling the terminal device, that is, to increase the scheduling period for scheduling the terminal device and/or reduce the amount of transmission resources for scheduling the terminal device, so as to improve the utilization rate of the transmission resources and save the air interface resources.

And when the first ratio is larger than the second threshold, the network equipment determines that the first scheduling strategy is used for indicating to stop scheduling the terminal equipment. That is, the probability that the network device receives the null data packet is greater than the second threshold within the first preset time period. At this time, even if the network device allocates the transmission resource 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 the padding data is high, so that the network device determines to stop scheduling the terminal device, and the transmission resource does not need to be allocated to the terminal device again, thereby saving the air interface resource.

It should be noted that, when the first ratio is smaller than the first threshold, the network device determines that the first scheduling policy is the current scheduling policy, that is, the scheduling policy for transmitting the first pre-scheduled data. That is, the scheduling period and the amount of transmission resources when the network device schedules the terminal device remain unchanged. In addition, it is easily understood that the first scheduling policy corresponding to the "first ratio equal to the first threshold" and the "first ratio equal to the second threshold" may be divided into the following three cases:

in case one, when the first ratio is equal to the first threshold, the network device determines that the first scheduling policy is a current scheduling policy 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 for indicating reduction of data amount for scheduling the terminal device.

And in case two, when the first ratio is equal to the first threshold, the network equipment determines that the first scheduling policy is the current scheduling policy for transmitting the first pre-scheduled data. And when the first ratio is equal to the second threshold, the network equipment determines that the first scheduling strategy is used for indicating to stop scheduling the terminal equipment.

And in case III, when the first ratio is equal to the first threshold, the network device determines that the first scheduling policy is used for instructing to reduce the data amount for scheduling the terminal device. And when the first ratio is equal to the second threshold value, the network equipment determines that the first scheduling strategy is used for indicating to stop scheduling the terminal equipment.

Therefore, when the network device determines that the first pre-scheduling data is the padding data, the network device determines a corresponding first scheduling policy by combining the probability of the received null data packet within the first preset time period, and when the probability of the received null data packet is lower, the first scheduling policy determined by the network device is to reduce the data amount for scheduling the terminal device. And when the probability of the received empty data packet is higher, the network equipment stops scheduling the terminal equipment so as to save empty resources. And the first threshold value and the second threshold value can be adjusted according to the actual service scene so as to meet the requirement of the actual service scene and reduce the times of invalid scheduling.

In addition, in order to facilitate the network device to count the probability of receiving a null data packet (i.e. the first pre-scheduled data in the data packet includes padding data and does not include traffic data) within the first preset time period, referring to fig. 6, in the case where the network device receives the first pre-scheduled data from the terminal device, the network device performs S403. In case the network device determines that the first pre-scheduled data includes padding data and does not include traffic data, the network device performs S404. Wherein, the specific descriptions of S403 and S404 are as follows:

and S403, the network equipment records the second value.

The second value may refer to the related description of S4021, and is not described herein again.

Illustratively, the network device updates the second value after receiving the first pre-schedule data. And the network device stores the corresponding relation between the identifier of the terminal device and the second value to indicate that the second value is the number of times that the network device receives the first pre-scheduling data from the terminal device in the first preset time period.

S404, when the first pre-scheduling data is filling data, the network equipment records a first numerical value.

The first numerical value may refer to the related description of S4021, and is not described herein again.

Illustratively, after the network device receives the first pre-scheduled data, the network device further performs validity detection on the first pre-scheduled data, and when it is determined that the first pre-scheduled data includes padding data and does not include service data, the network device updates the first value, and the network device stores a correspondence between the identifier of the terminal device and the first value to indicate that the first value is the number of times that the network device receives the first pre-scheduled data from the terminal device as the padding data in the first preset time period.

It should be noted that the network device may perform S403 first and then perform S404. The network device may also perform S404 and then S403. The network device may also perform S403 and S404 simultaneously. The embodiment of the present application does not limit the execution sequence of S403 and S404.

Therefore, the network equipment updates the first value and the second value in real time, so that the network equipment can conveniently count the probability of receiving the empty data packet in the first preset time period.

It should be noted that, if the network device adopts the following counting method: and adding one to the first value on the original basis every time the first pre-scheduling data is determined to be filling data, and adding one to the second value on the original basis every time the first pre-scheduling data is received, deleting the first value and the second value once every time the network equipment is spaced by the duration of one first preset time period so as to re-count the first value and the second value in the next first preset time period, so that the network equipment accurately counts the probability of receiving empty data packets in the first preset time period. In addition, the network device may also adopt the following counting method: recording corresponding first time when the first pre-scheduling data is determined to be filling data every time, and taking the number of the first time in a first preset time period as a first numerical value; and recording corresponding second time every time the first pre-scheduling data is received, and taking the number of the second time in the first preset time period as a second numerical value.

In some embodiments, in the case that the first scheduling policy is used to instruct to reduce the data amount for scheduling the terminal device, referring to fig. 7, the communication method according to this embodiment further includes the following steps:

s405, the network equipment sends second uplink authorization information to the terminal equipment. Accordingly, the terminal device receives the second uplink grant 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 is determined by the first scheduling policy.

S406, the terminal equipment encodes and modulates the second pre-scheduling data according to the MCS in the second uplink authorization information, and transmits the encoded and modulated second pre-scheduling data at the position of the RB indicated by the second uplink authorization information. Accordingly, 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-scheduled data comprises traffic data and/or padding data.

Here, after the terminal device receives the second uplink grant information, if the terminal device has service data to be transmitted, the second pre-scheduled data includes the service data but does not include padding data, or the second pre-scheduled data includes the service data and the padding data. And if the terminal equipment does not have the service data to be transmitted, the second pre-scheduling data comprises the filling data and does not comprise the service data.

Correspondingly, after the network device receives the second pre-scheduled data, the network device still performs validity detection on the received second pre-scheduled data.

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

The second ratio is a ratio of a third value to a fourth value, the third value is the number of times that the second pre-scheduling data received by the network device in the second preset time period is padding data, and the fourth value is the number of times that the second pre-scheduling data received by the network device in the second preset time period is padding data. 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.

For example, in the case that the network device receives the second pre-scheduling data, the network device updates the fourth value, that is, the number of times that the network device receives the second pre-scheduling data in the second preset time period is increased by one. After the network device performs validity detection on the second pre-scheduling data, if the second pre-scheduling data includes padding data and does not include service data, the network device updates a third value, that is, the number of times that the second pre-scheduling data received by the network device within a second preset time period is padding data is increased by one.

And S408, the network equipment determines a second scheduling strategy according to the second ratio.

Illustratively, the network device presets a third threshold and a 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.

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

It should be noted that the scheduling policy corresponding to "the second ratio is equal to the third threshold" and "the second ratio is equal to the fourth threshold" may be divided into the following three cases:

in case one, when the second ratio is equal to the third threshold, the network device determines that the second scheduling policy is a scheduling policy 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 the first scheduling policy, that is, the scheduling policy for transmitting the second pre-scheduled data.

And in case two, when the second ratio is equal to the third threshold, the network device determines that the second scheduling policy is the scheduling policy for transmitting the first pre-scheduled data. And when the second ratio is equal to the fourth threshold, the network equipment determines that the second scheduling policy is used for indicating that the terminal equipment is stopped to be scheduled.

And in case three, when the second ratio is equal to the third threshold, the network device determines that the second scheduling policy is the first scheduling policy, that is, the scheduling policy for transmitting the second pre-scheduled data. And when the second ratio is equal to the fourth threshold, the network equipment determines that the second scheduling policy is used for indicating that the terminal equipment is stopped to be scheduled.

In this way, the network device determines the corresponding second scheduling policy according to the condition of the second pre-scheduled data (e.g., the probability of an empty data packet) received within the second preset time period, so as to save air interface resources. And the third threshold and the fourth threshold can be adjusted according to the actual service scene to meet the requirement of the actual service scene and reduce the times of invalid scheduling.

In addition, in order to facilitate the network device to count the probability of receiving a null data packet (i.e. the second pre-scheduled data in the data packet includes padding data and does not include traffic data) within the second preset time period, referring to fig. 8, in the case that the network device receives the second pre-scheduled data from the terminal device, the network device performs S409. In case the network device determines that the second pre-scheduled data includes padding data and does not include traffic data, the network device performs S410. Wherein, the specific description of S409 and S410 is as follows:

and S409, recording a fourth numerical value by the network equipment.

The fourth value can refer to the related description of S407, and is not described herein again.

Illustratively, the network device updates the fourth value after receiving the second pre-scheduled data. And the network device stores the corresponding relation between the identifier of the terminal device and the fourth value to indicate that the fourth value is the number of times that the network device receives second pre-scheduling data from the terminal device in a second preset time period.

And S410, when the second pre-scheduled data is the filling data, the network equipment records a third numerical value.

The third value can refer to the related description of S407, and is not described herein again.

Illustratively, after the network device receives the second pre-scheduled data, the network device further performs validity detection on the second pre-scheduled data, and when it is determined that the second pre-scheduled data is padding data and does not include service data, the network device updates the third value. And the network device stores the corresponding relation between the identifier of the terminal device and the third value to indicate that the third value is the number of times that the network device receives second pre-scheduling data from the terminal device in a second preset time period as filling data.

Therefore, the network equipment updates the third value and the fourth value in real time, so that the network equipment can count the probability of receiving the empty data packet in 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 can accurately count the probability of receiving the null data packet in the second preset time period.

In some embodiments, the network device further determines a corresponding scheduling policy according to a condition of the first pre-scheduled data. S402 may also be implemented specifically: when the first pre-scheduling data comprises the filling data and does not comprise the service data, the network equipment determines a scheduling policy for indicating that the terminal equipment is stopped to be scheduled. When the first pre-scheduled data includes the service data, or includes the padding data and the service data, the network device determines the scheduling policy as a current scheduling policy, that is, a scheduling policy for transmitting the first pre-scheduled data.

Therefore, the network equipment determines the corresponding scheduling strategy according to the current first pre-scheduling data, so that the air interface resources can be saved, the times of invalid scheduling are reduced, and the implementation complexity is reduced.
