In order to facilitate understanding of the embodiments of the present application, a communication network system on which the terminal device of the present application is based is described below. Please refer to fig. 2.

As shown in fig. 2, the communication network system is a non-terrestrial network (NTN) system, and the NTN system includes: user Equipment (UE) 201, a satellite 202, and a network device 203, which are in turn in communication connection.

In some implementations, for the delay-sensitive service, because there is no fixed mapping between the process identifier of the HARQ process and the retransmission policy, the network device sends the identifier of the HARQ process and the retransmission policy to the terminal device each time, which results in a large transmission overhead. In this application, the inventor thinks of mapping between the process identifier of the fixed HARQ process and the retransmission policy, and the network device only sends an indication of a small number of times to the terminal device, so that the terminal device can send data of the delay-sensitive service to the network device.

In the related art, the network device sends the identifier of the HARQ process and the retransmission policy to the terminal device each time, which results in a large transmission overhead.

In order to reduce transmission overhead, the present application provides various embodiments based on the above-mentioned hardware structure of the terminal device and the communication network system.

Fig. 3 is a first flowchart of a communication method according to an embodiment of the present application. As shown in fig. 3, the communication method includes:

s31, the network device determines the transmission resource of the terminal device for sending the first data according to the network parameter and/or the data volume of the first data.

Optionally, the network parameters include at least one of: an air interface rate; transport block size.

Optionally, the first data is data to be sent by the terminal device to the network device. Optionally, the data amount may be included in a Buffer Status Report (BSR) sent by the terminal device, or may be included in other signaling. The BSR is a report sent by the terminal device to the network device before sending the first data to the network device.

Optionally, the transmission resource comprises at least one of: a first number of transmissions; a first transmission duration.

For example, when the network parameter includes an air interface rate and the transmission resource includes a first transmission duration, determining the transmission resource according to the network parameter and the data volume of the first data includes: and determining the ratio of the data volume to the air interface rate as a first transmission time length.

For example, when the data amount is 2MB (megabyte) and the air interface rate is 1Mbps (megabyte per second), the ratio of the data amount to the air interface rate is equal to 2, and thus the first transmission duration is 2 seconds.

For example, when the network parameter includes a transport block size and the transmission resource includes a first transmission number, determining the transmission resource according to the network parameter and a data amount of the first data includes: determining the ratio of the data volume to the size of the transmission block; if the ratio is an integer, determining the ratio as a first transmission frequency; and/or if the ratio is a non-integer, determining an integer which is larger than the ratio and has the smallest difference with the ratio as the first transmission time.

For example, if the data amount is 2MB and the transport block size is 1MB, the ratio of the data amount to the transport block size is 2 (i.e., 2/1= 2), and since the ratio 2 is an integer, the first transmission number is equal to 2.

For example, if the data amount is 2.5MB and the transport block size is 1MB, the ratio of the data amount to the transport block size is equal to 2.5 (i.e., 2.5/1= 2.5), and since the ratio of 2.5 is a non-integer, the first transmission number is equal to 3 (3 is an integer greater than 2.5 and having the smallest difference from 2.5).

S32, the network device sends a first instruction to the terminal device according to the transmission resource, where the first instruction is used to instruct the terminal device to send a sending policy of the first data to the network device.

Optionally, the retransmission policy of the N HARQ processes and/or the retransmission policy of the logical channel is to prohibit retransmission. The logical channel is a logical channel to which the BSR belongs.

Optionally, the first indication is contained in at least one of the following information: radio Resource Control (RRC) signaling (e.g., RRC Reconfiguration), Media Access Control (MAC) Control Element (CE) signaling, or Downlink Control Information (DCI). Alternatively, the MAC CE signaling is usually transmitted on a Physical Uplink Shared Channel (PUSCH), and the DCI is usually transmitted on a Physical Downlink Control Channel (PDCCH).

a table index;

and the N process identifications respectively correspond to second transmission time lengths.

Optionally, the table index indicates a configuration table, and the configuration table may include N process identifiers.

Optionally, the N process identifiers may indicate N HARQ processes, and each of the N process identifiers indicates one HARQ process. The product of N and the second number of transmissions equals the first number of transmissions. The second transmission duration is equal to the product of the second transmission times and the preset duration.

It should be noted that, when the transmission resource is the first transmission number, the first indication may be sent to the terminal device according to the first transmission number in the following 3 manners (manners 11, 12, and 13).

Mode 11, when the first indication comprises a table index; sending a first indication to the terminal device according to the transmission resource, comprising:

judging whether to send a first instruction to the terminal equipment or not according to the transmission resources; if so, updating the first configuration table currently used as a second configuration table, determining a table index of the second configuration table as a first indication, and sending the first indication to the terminal equipment; and/or if not, not sending the first indication to the terminal equipment.

For example, when the transmission resource includes a first transmission number, determining whether to send a first instruction to the terminal device according to the transmission resource includes: acquiring a first number of process identifiers corresponding to the retransmission prohibition from a first configuration table; if the first number is not equal to the first transmission times, sending a first indication to the terminal equipment; and/or if the first number is equal to the first transmission times, not sending the first indication to the terminal equipment. Alternatively, "not equal to" may be greater or less than. When the transmission resource comprises the first transmission times, in the second configuration table, the retransmission strategy is that the number of the process identifications for prohibiting retransmission is equal to the first transmission times.

For example, when the transmission resource includes a first transmission duration, determining whether to send a first indication to the terminal device according to the transmission resource includes: acquiring a first number of process identifiers corresponding to the retransmission prohibition from a first configuration table; if the total transmission time length corresponding to the first quantity is not equal to the first transmission time length, sending a first indication to the terminal equipment; and/or if the total transmission time length corresponding to the first number is equal to the first transmission time length, not sending the first indication to the terminal equipment. Alternatively, "not equal to" may be greater or less than. When the transmission resource comprises a first transmission duration, in the second configuration table, the retransmission strategy is that the total transmission duration corresponding to the number of the process identifiers for prohibiting retransmission is equal to the first transmission duration.

When the first indication includes the table index, the network device may transmit the configuration information to the terminal device before S31. Optionally, the configuration information may be included in RRC signaling (e.g., RRC Setup).

The configuration information comprises at least one table index and configuration tables corresponding to the at least one table index, each configuration table comprises at least one process identifier and a retransmission strategy corresponding to the at least one process identifier, and the retransmission strategy is to prohibit retransmission and start retransmission. For example, the total number of at least one table index is 3, and the 3 table indexes may be 01, 02, and 03, respectively. Optionally, the total number of the at least one process identifier included in the configuration table corresponding to the table index may be 7, and the 7 process identifiers are 0, 1, 2, 3, 4, 5, and 6, respectively.

Exemplarily, the configuration table 1 indicated by 01 is as follows.

Configuration table 1

Process identification	0	1	2	3	4	5	6
								Retransmission strategy	Initiating retransmission	Initiating retransmission	Initiating retransmission	Initiating retransmission	Inhibiting retransmission	Inhibiting retransmission	Inhibiting retransmission

Exemplarily, the configuration table 2 indicated by 02 is as follows.

Configuration table 2

Process identification	0	1	2	3	4	5	6
								Retransmission strategy	Initiating retransmission	Initiating retransmission	Initiating retransmission	Initiating retransmission	Initiating retransmission	Inhibiting retransmission	Inhibiting retransmission

Exemplarily, the configuration indicated by 03 is shown in table 3 below.

Configuration table 3

Process identification	0	1	2	3	4	5	6
								Retransmission strategy	Initiating retransmission	Initiating retransmission	Inhibiting retransmission	Inhibiting retransmission	Inhibiting retransmission	Inhibiting retransmission	Inhibiting retransmission

For example, when the first configuration table is configuration table 2, the first number of process identifiers (i.e., process identifiers 5 and 6) corresponding to the retransmission prohibition is obtained from the first configuration table and is equal to 2.

For example, when the network device determines that the first transmission number is equal to 5 and the first configuration table is the configuration table 2, only the HARQ processes indicated by the process identifiers 5 and 6 respectively may be used for transmission of the first data, and when the HARQ processes indicated by the process identifiers 5 and 6 respectively are both occupied, because the number of the HARQ processes is not enough (less than 5, that is, retransmission is prohibited in the first transmission number and the first configuration table), even if an air interface of the network device has sufficient resources, the terminal device may not be scheduled again, but only after the HARQ processes indicated by the process identifiers 5 and 6 respectively are in an idle state, the terminal device may be scheduled again, so that a time delay for the terminal device to send the first data is increased. Therefore, in order to reduce the delay of the terminal device for sending the first data, the network device changes the first configuration table to a second configuration table (for example, configuration table 3). In the second configuration table, the process identifier of which the retransmission policy is prohibited includes 5 retransmission policies, namely the

process identifiers

2, 3, 4, 5, and 6, which are prohibited from being retransmitted, so that when the network device schedules the terminal device by using the processes respectively indicated by the

process identifiers

2, 3, 4, 5, and 6, it is not necessary to wait for the HARQ process to be in an idle state, and the time delay for the terminal device to send the first data is reduced.

In the mode 12, the transmission resource includes a first transmission frequency, and the first indication includes N process identifiers and second transmission frequencies corresponding to the N process identifiers; according to the transmission resource, sending a first indication to the terminal equipment, wherein the first indication comprises:

determining N process identifications and/or second transmission times corresponding to the N process identifications according to the first transmission times; if N is larger than or equal to a preset value, determining the second transmission times corresponding to the N process identifications and the N process identifications as first instructions, and sending the first instructions to the terminal equipment; and/or if the N is smaller than the preset value, not sending the first indication to the terminal equipment.

In this manner, the retransmission policy corresponding to the N process identifiers is to prohibit retransmission.

Alternatively, when the first number of transmissions is 6, N may be equal to 1, 2, 3, 6.

For example, when N is equal to 1, it may be determined that the second number of transmissions corresponding to 1 process identification is equal to 6.

For example, when N is equal to 2, it may be determined that the second transmission times corresponding to 2 process identifiers are equal to 3.

For example, when N is equal to 3, it may be determined that the second transmission times corresponding to 3 process identifiers are equal to 2.

For example, when N is equal to 6, it may be determined that the second transmission times corresponding to the 6 process identifications are equal to 1.

Alternatively, the preset value may be 0.

When the preset values are 0, N is equal to 1, and the second transmission number is equal to 6, the network device may determine any one process identifier (for example, process identifier 2) whose retransmission policy is to prohibit retransmission at this time as the process identifier included in the first indication.

When the preset values are 0, N is equal to 2, and the second transmission number is equal to 3, the network device may determine any two process identifiers (for example, process identifier 2 and process identifier 3) whose retransmission policy is to prohibit retransmission at this time as the process identifiers included in the first indication.

Alternatively, the second number of transmissions may be a number of transmissions that are only effective at the current scheduling time.

For example, when the second transmission number is effective at the current scheduling time, if N is equal to 1 and the second transmission number is equal to 6, the network device needs to send the first indication 6 times to the terminal device. After the network device sends the first indication to the terminal device each time, the terminal device performs data transmission by using an HARQ process corresponding to one process identifier (e.g., process identifier 2).

Optionally, the 6 times of the first indication sent by the network device to the terminal device may be the same or different.

For example, when the first instructions sent by the network device to the terminal device 6 times are the same, the first instructions sent each time include: 1 (N) and 1 (number of transmissions).

For example, when the 6 times of first indications sent by the network device to the terminal device are different, the 6 times of first indications sent sequentially include: 1 (representing the first indication sent for the first time) and 1 (the number of transmissions), 2 (representing the first indication sent for the second time) and 1 (the number of transmissions), 3 (representing the first indication sent for the third time) and 1 (the number of transmissions), 4 (representing the first indication sent for the fourth time) and 1 (the number of transmissions), 5 (representing the first indication sent for the fifth time) and 1 (the number of transmissions), and 6 (representing the first indication sent for the sixth time) and 1 (the number of transmissions).

In the mode 13, the transmission resource includes a first transmission frequency, and the first indication includes N process identifiers and second transmission durations corresponding to the N process identifiers, respectively; according to the transmission resource, sending a first indication to the terminal equipment, wherein the first indication comprises:

determining N process identifications and/or second transmission times corresponding to the N process identifications according to the first transmission times; if N is larger than or equal to a preset value, determining second transmission time length corresponding to the N process identifications according to the preset time length and second transmission times corresponding to the N process identifications; determining the second transmission duration corresponding to the N process identifications and the N process identifications as a first indication, and sending the first indication to the terminal equipment; and/or if the N is smaller than the preset value, not sending the first indication to the terminal equipment.

It should be noted that, in the manner 12 and the manner 13, the methods for determining the N process identifiers and/or the second transmission times corresponding to the N process identifiers are the same, and details are not described here again.

The preset time length is the time length required by one HARQ process for transmitting data once. Alternatively, the preset time period may be 10 milliseconds, 9 milliseconds, or the like. For example, when the preset time length is 10 ms, if N is equal to 1 and the second transmission number is equal to 6, the transmission time length corresponding to 1 process identifier is equal to 60 ms.

Optionally, on the basis of the method 13, a total duration of the second transmission durations corresponding to the N process identifiers and the N process identifiers may be determined as the first indication. For example, when the preset time duration is 10 ms, if N is equal to 2 and the second transmission number is equal to 3, the total time durations of the second transmission time durations corresponding to the 2 process identifiers are respectively equal to 30 ms.

Optionally, on the basis of the modes 12 and 13, the S31 specifically includes: the network equipment judges whether the retransmission strategy corresponding to the logic channel is retransmission prohibition; if so, determining transmission resources for the terminal equipment to send the first data according to the network parameters and/or the data volume of the first data; and/or if not, determining the transmission resource for the terminal equipment to send the first data according to the network parameter and/or the data volume of the first data.

And S33, the terminal equipment sends the first data to the network equipment according to the sending strategy indicated by the first indication.

For example, when the first indication includes a table index, on the basis of the foregoing manner 11, the terminal device may determine, in at least one configuration table stored in advance, a second configuration table corresponding to the table index, where the second configuration table includes N process identifiers whose retransmission policy is to prohibit retransmission; and sending first data to the network equipment by adopting the N HARQ processes indicated by the N process identifiers.

Illustratively, when the table index is 03, then the configuration table 3 indicated by the table index 03 is determined to be the second configuration table. In the configuration table 3, since the N process identifiers whose retransmission policy is to prohibit retransmission include the

process identifiers

2, 3, 4, 5, and 6, the HARQ processes respectively indicated by the

process identifiers

2, 3, 4, 5, and 6 may be used to send the first data to the network device.

When the first instruction includes the table index, on the basis of the above-described mode 11, before S33, the method further includes: and the terminal equipment receives the configuration information sent by the network equipment.

For example, when the first indication includes N process identifiers and respective corresponding second transmission times of the N process identifiers, on the basis of the foregoing manner 12, the terminal device sets the retransmission policy of the N HARQ processes indicated by the N process identifiers as a retransmission prohibition; and according to the second transmission times corresponding to the N process identifications, sequentially sending the first data through N HARQ processes with retransmission strategy setting as retransmission prohibition.

The following describes a schematic structure diagram of sending the first data by taking N equal to 1 and the second transmission number equal to 6 as an example, with reference to fig. 4. Fig. 4 is a first schematic structural diagram of sending first data provided in the present application. As shown in fig. 4, for example, the network device sends a first indication to the terminal device through DCI, where the first indication includes a process identifier 2(ID =2) and a first transmission number (T = 6). And modifying the retransmission strategy corresponding to the process identifier 2 into a retransmission prohibition strategy. After receiving the first indication, the terminal device adopts the HARQ process indicated by the process identifier 2 to completely send the first data to the network device on the PUSCH through 6 transmissions. During the 6 transmissions, repeated transmission of data is prohibited.

The following describes a schematic structure diagram of sending the first data by taking N equal to 2 and the second transmission number equal to 3 as an example, with reference to fig. 5. Fig. 5 is a second schematic structural diagram of sending first data provided in the present application. As shown in fig. 5, for example, the network device sends a first indication to the terminal device through one DCI, where the first indication includes a process identifier 2(ID =2) and a second transmission number (T =3), and the network device sends the first indication to the terminal device through another DCI, where the first indication includes a process identifier 3(ID =3) and a second transmission number (T = 3). After the terminal device receives the process identifier 2(ID =2) and the second transmission number (T =3), and the process identifier 3(ID =3) and the second transmission number (T =3), according to the second transmission number, the terminal device transmits the first data completely to the network device on the PUSCH by using the HARQ process indicated by the process identifier 2 and the HARQ process indicated by the process identifier 3, respectively.

Fig. 4 and 5 are illustrated with a first indication included in DCI.

It should be noted that, when N is greater than 1, a first indication needs to be sent through a plurality of DCIs, where each first indication includes a process identifier and a second transmission frequency corresponding to the process identifier. For example, in fig. 5, N =2, so 2 first indications are transmitted to the network device over 2 DCIs. And/or, when N is greater than 1, a first indication may also be sent to the terminal device by one MAC CE, where the first indication may include a plurality of process identifiers and a second number of transmission times corresponding to each process identifier.

For example, when the first indication includes N process identifiers and second transmission durations corresponding to the N process identifiers, on the basis of the foregoing manner 13, the retransmission policy of the N HARQ processes indicated by the N process identifiers is set to prohibit retransmission; and respectively transmitting the first data through N HARQ processes of which the retransmission strategies are forbidden in sequence in second transmission time lengths corresponding to the N process identifications respectively.

For example, when N is equal to 1, the second transmission number is equal to 6, and the transmission duration corresponding to 1 process identifier (e.g., process identifier 2) is equal to 60 milliseconds, the first data is sent in the HARQ process indicated by the process identifier 2 whose retransmission is prohibited using the retransmission policy within 60 milliseconds.

For example, when N is equal to 2, the second transmission number is equal to 3, and the transmission duration corresponding to each of 2 process identifiers (e.g., process identifier 2 and process identifier 3) is equal to 30 milliseconds, in one 30 milliseconds, a part of the first data is transmitted by using the HARQ process indicated by the process identifier 2 whose retransmission is prohibited, and in another 30 milliseconds, another part of the first data is transmitted by using the HARQ process indicated by the process identifier 3 whose retransmission is prohibited.

Optionally, after the first data is sent by using the HARQ process, the retransmission policy of the HARQ process is set to start retransmission. For example, in fig. 4, after the first data is completely transmitted, the retransmission policy corresponding to the process identifier 2 is modified to start retransmission. And/or, for example, in fig. 5, after the first data is completely transmitted, the retransmission policy corresponding to each of the process identifier 2 and the process identifier 3 is set to start retransmission.

The communication method provided by the embodiment of fig. 3 comprises the following steps: the network equipment determines transmission resources for the terminal equipment to send the first data according to the network parameters and/or the data volume of the first data; the network equipment sends a first instruction to the terminal equipment according to the transmission resource, wherein the first instruction is used for instructing the terminal equipment to send a sending strategy of first data to the network equipment; and the terminal equipment sends the first data to the network equipment according to the sending strategy indicated by the first indication. In the method, the network equipment sends the first indication to the terminal equipment according to the transmission resource, and the terminal equipment sends the first data to the network equipment according to the sending strategy of the first indication, so that the network equipment is prevented from sending the identifier of the HARQ process and the retransmission strategy to the terminal equipment every time, and the transmission overhead between the transmission network equipment and the terminal equipment is reduced.

Fig. 6 is a second flowchart of a communication method according to an embodiment of the present application. As shown in fig. 6, the method includes:

s61, the network device responds to the data volume of the first data meeting a first preset condition and/or the current network parameter meeting a second preset condition.

Optionally, the data amount satisfies a first preset condition, and includes at least one of: the data amount is greater than a first threshold; alternatively, the amount of data is less than or equal to the first threshold.

The current network parameters are network parameters of the network device. Optionally, the network parameter satisfies a second preset condition, including at least one of: the network parameter is greater than a second threshold; or the network parameter is less than or equal to the second threshold.

For example, the network device may respond to the amount of data being greater than a first threshold and the network parameter being less than or equal to a second threshold,

for example, the network device may respond to the amount of data being less than or equal to a first threshold and the network parameter being greater than a second threshold.

It should be noted that, in the present application, the air interface rate and the transport block size may be switched with each other. For example, the transport block size may be translated to an air rate.

S62, the network equipment determines the transmission resource of the terminal equipment for sending the first data.

For example, when the transmission resource includes the first transmission duration and the network parameter includes an air interface rate, determining the transmission resource for the terminal device to send the first data includes:

For example, when the transmission resource includes a first transmission number and the network parameter includes a transport block size, determining the transmission resource for the terminal device to transmit the first data includes:

determining the ratio of the data volume to the size of the transmission block; if the ratio is an integer, determining the ratio as a first transmission frequency; and/or if the ratio is a non-integer, determining an integer which is larger than the ratio and has the smallest difference with the ratio as the first transmission time.

S63, the network device sends a first instruction to the terminal device according to the transmission resource, where the first instruction is used to instruct the terminal device to send a sending policy of the first data to the network device.

Optionally, the first indication is contained in at least one of the following information: RRC signaling, MAC CE signaling, or DCI.

Optionally, the first indication comprises at least one of the following information: a table index; n process identifications and N corresponding second transmission times of the process identifications; or the N process identifications and the N process identifications respectively correspond to a second transmission time length.

Alternatively, the first indication may be sent in 3 ways (ways 21, 22, 23) as follows.

Mode 21, when the first indication includes a table index, sending the first indication to the terminal device according to the transmission resource, including:

For example, when the transmission resource includes a first transmission number, determining whether to send a first instruction to the terminal device according to the transmission resource includes: acquiring a first number of process identifiers corresponding to the retransmission prohibition from a first configuration table; if the first number is not equal to the first transmission times, sending a first indication to the terminal equipment; and/or if the first number is equal to the first transmission times, not sending the first indication to the terminal equipment.

If the first instruction is sent to the terminal device by the method 21, before S61, the method further includes: and sending the configuration information to the terminal equipment. It should be noted that the implementation method of the mode 21 is the same as the implementation method of the mode 11, and the implementation process of the mode 21 is not described herein again.

The method 22, when the transmission resource includes a first transmission frequency, and the first indication includes N process identifiers and second transmission frequencies corresponding to the N process identifiers, sending the first indication to the terminal device according to the transmission resource, including:

It should be noted that the implementation method of the manner 22 is the same as the implementation method of the manner 12, and the implementation process of the manner 22 is not described herein again.

Mode 23, when the transmission resource includes the first transmission frequency, and the first indication includes N process identifiers and second transmission durations corresponding to the N process identifiers, sending the first indication to the terminal device according to the transmission resource, including:

determining N process identifications and/or second transmission times corresponding to the N process identifications according to the first transmission times; if N is larger than or equal to a preset value, determining second transmission time length corresponding to the N process identifiers according to a preset time length and second transmission times corresponding to the N process identifiers, determining the second transmission time length corresponding to the N process identifiers and the second transmission times corresponding to the N process identifiers as a first indication, and sending the first indication to the terminal equipment; and/or if the N is smaller than the preset value, not sending the first indication to the terminal equipment.

It should be noted that the implementation method of the manner 23 is the same as the implementation method of the manner 13, and the implementation process of the manner 22 is not described herein again.

Optionally, on the basis of the foregoing manners 22 and 23, in response to that the data amount in response to the first data satisfies the first preset condition and/or that the current network parameter satisfies the second preset condition, the method specifically includes:

the network device needs to judge whether the retransmission strategy corresponding to the logical channel is to prohibit retransmission; if so, executing the first step that the data volume responding to the first data meets a first preset condition and/or the current network parameter meets a second preset condition; and/or the presence of a gas in the gas,

if not, the first data is not responded, the data volume of the first data meets the first preset condition, and/or the current network parameter meets the second preset condition.

Optionally, the retransmission policy of the N HARQ processes and/or the retransmission policy of the logical channel is to prohibit retransmission.
