With the development of relay technology, cache assisted relay is more and more concerned by academia and industry. The relay base station is provided with a certain amount of buffer space, so that the relay base station can buffer the received data firstly and then send the data out in a proper time.

Due to the time-varying nature of the wireless channel, no matter the relay base station chooses to receive or transmit the data packet, there is a certain probability of failure (packet loss) in a certain time slot.
In view of the above problems in the related art, no effective solution has been proposed.

In this embodiment, a relay transmission scheduling method is provided, and fig. 2 is a flowchart of a relay transmission scheduling method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, acquiring a random number in an idle time slot, wherein the value range of the random number is [0,1 ];
in this embodiment, the idle time slot includes a time slot before the relay base station does not perform the operation of transmitting or receiving the data packet, where the time slot before the operation of transmitting or receiving the data packet is not performed may be after the last transmission or reception of the data packet is performed, or may be a time slot when the relay base station is used for the first time.
X represents a random number for representing the probability of successfully receiving or transmitting a data packet when the simulated relay base station operates normally, for example, when the random number x is 0.32, the probability of successfully receiving or transmitting a data packet by the simulated relay base station may be represented as 0.32; since the relay base station may or may not successfully receive or transmit the data packet, the value range of the random number x is [0,1 ].
It should be noted that the random number x is only used to indicate the probability of successful transmission or reception of the data packet of the relay base station in the analog state, and is not the probability of successful reception or transmission of the actual data packet of the relay base station; the random number may be generated by a random number generation algorithm, such as a Python random number generation algorithm, or may be generated by a hardware random number generator, such as by an RDRAND instruction in a chip, and the generated random number may be repeated or not, and the random number may be transmitted in the form of an analog signal or a digital signal, which is not described herein again.
Step S204, acquiring the number m of data packets stored in the relay base station, and comparing the m with a first preset threshold value to obtain a first comparison result, wherein the m is greater than or equal to 0;
in this embodiment, the manner of obtaining the number m of the data packets stored in the relay base station may be obtained by scanning the data packets in the relay base station, or by reading the data packets stored in the relay base station, or by recording the number of the received and transmitted data packets in real time and performing calculation based on the number, or by other manners, as long as the number m of the data packets stored in the relay base station can be obtained, which is not described herein again.
The first preset threshold h is represented by h, and the first preset threshold may be determined according to the maximum storage amount of the data packet in the relay base station, or may be determined according to a data packet transceiving policy of the relay base station, that is, the first preset threshold h may be used to represent the maximum allowable storage amount of the data packet in the relay base station, or may be an alert value representing the storage amount of the data packet in the relay base station.
For example, when the number m of data packets in the relay base station reaches the first preset threshold h, the ratio of the working state of the relay base station for sending the data packets to the working time in unit time is increased; similarly, when the number m of the data packets in the relay base station does not reach the first preset threshold h, the ratio of the working state of the relay base station for receiving the data packets to the working time in unit time is increased.
It should be noted that, since the relay base station is a relay device for data transmission, the number m of data packets stored in the relay base station may be greater than 0, or equal to 0, where when the number m of data packets is equal to 0, it indicates that no data packet is stored in the relay base station, and when m is greater than 0, it indicates that a certain number of data packets to be transmitted are stored in the relay base station.
Step S206, determining a target condition based on the first comparison result;
in this embodiment, when the first comparison result is that the number m of the data packets is greater than the first preset threshold h, it indicates that the number m of the data packets in the relay base station exceeds the first preset threshold h, which may cause the relay base station not to receive the data packets in time, thereby causing data packet loss, and therefore, it is determined that the target condition is the first target condition at this time, so that the working state of the relay base station is mainly based on sending the data packets, thereby enabling the relay base station to receive the data packets in time; on the contrary, the number of the data packets in the relay base station is not enough to support the relay base station to continuously send the data packets, which may cause data packet loss, and at this time, the target condition is determined to be a second target condition so that the working state of the relay base station is mainly based on receiving the data packets, so that the relay base station can send the data packets in time; by the method, the data packet in the relay base station is dynamically kept near the first preset threshold h to ensure that the relay base station can continuously keep the state of normally receiving or sending the data packet, and the data packet caused by untimely data receiving or sending due to the relay base station being in a certain state continuously is avoided.
Step S208, judging whether the random number meets the target condition;
in this embodiment, since the random number is used to simulate the probability of receiving or transmitting a data packet by the relay base station in the normal operating state, whether the probability of transmitting or receiving a data packet by the relay base station in the normal operating state satisfies the target condition is simulated by determining whether the random number satisfies the target condition.
For example, when the random number x satisfies the first target condition, it is determined that the probability of receiving the packet by the relay base station in the state satisfies the first target condition, so that the relay base station performs the packet receiving operation, and similarly, when the random number x does not satisfy the first target condition, it is determined that the probability of receiving the packet by the relay base station in the state does not satisfy the first target condition, so that the relay base station performs the datagram transmitting operation, and so on.
It should be noted that, because the relay base station may receive or transmit a large number of data packets simultaneously in a unit time, fixing the number of data packets of the relay station to the first preset threshold h may cause the relay base station to be in a state of receiving or transmitting data packets continuously in a period of time, and at this time, may cause the relay base station to be unable to receive or transmit data packets in the period of time, thereby causing a data packet loss.
Step S210, determining the data transmission direction of the relay base station based on the determination result.
In this embodiment, when the determination result is that the random number x satisfies the first target condition, determining that the data transmission direction of the relay base station is to receive the data packet from the macro base station, and otherwise determining that the data transmission direction of the relay base station is to send the data packet to the user terminal; similarly, when the judgment result is that the random number x does not satisfy the second target condition, determining that the data transmission direction of the relay base station is to receive the data packet from the macro base station, and otherwise, determining that the data transmission direction of the relay base station is to send the data packet to the user terminal.
It should be noted that the data transmission direction determined based on the determination result may be adjusted according to an actual use situation, that is, when the determination result is that the random number x satisfies the first target condition, the data transmission direction of the relay base station is determined to be sending the data packet to the user side, otherwise, the data transmission direction of the relay base station is determined to be receiving the data packet from the macro base station, or other data transmission directions, which is not the only solution in this embodiment.
Through the steps, the relay base station sends and receives the data packets under the condition of meeting a certain condition through the preset threshold and the random number, and the quantity m of the data packets stored on the random number by the relay base station is ensured to float near the first preset threshold h, so that the problem of low data transmission precision caused by packet loss when the relay base station receives or sends the data packets in the related technology is solved, and the data distortion and the data transmission precision are improved and reduced.
The main body of the above steps may be a base station, a terminal, etc., but is not limited thereto.
In an alternative embodiment, determining the target condition based on the first comparison result comprises:
step S2062, determining that the target condition is a first target condition under the condition that the first comparison result is used for indicating that m is greater than a first preset threshold value;
step S2064 determines that the target condition is the second target condition when the first comparison result indicates that m is smaller than the first preset threshold.
In the present embodiment, in the case where the target condition is the first target condition, the first target condition is that the random number x is smaller than
In the formula, p1The probability that the relay base station successfully receives the data packet from the macro base station is p2, and the probability that the user terminal successfully receives the data packet from the relay base station is p 2; in the case where the target condition is a second target condition, the second target condition is that the random number x is smaller than
From the above conditions, when m is less than 2h,
has a value of
When m is 0, the compound (A) is,
has a value of 1.
In an optional embodiment, in a case where the target condition is determined to be the first target condition, determining the data transmission direction of the relay base station based on the determination result includes:
step S2066, under the condition that the judgment result is used for indicating that the random number meets the first target condition, the transmission direction is determined to be receiving the data packet from the macro base station;
step S2068, in the case that the determination result is used to indicate that the random number does not satisfy the first target condition, determining that the transmission direction is to transmit the data packet stored in the relay base station to the user end.
In this embodiment, when the number m of data packets in the relay base station is close to (greater than or less than) the first preset threshold h, in order to ensure that the number m of data packets in the relay base station floats around the first preset threshold h, the operating state of the relay base station needs to be mainly based on the sending of the data packets, and at this time, the relay base station needs to be in a working state mainly based on the sending of the data packets
Has a value of
Then judging whether the random number x is larger than
And when the random number is larger than x, indicating the relay base station to send the data packet, otherwise, indicating the relay base station to receive the data packet.
Since the random number is randomly generated, x may be greater than
May also be less than
So that the number m of data packets stored in the relay base station is floated with the change of the random number x, but at this time, p can be preset2And p1X is greater than
The probability of (2) is greater, so that the working state of the relay base station is mainly to transmit data packets.
For example, when p1＝0.8，p2When h is 0.5, h is 10 and m is 12, the formula
The value of (a) is equal to about 0.3, and the probability that x is greater than 0.3 is 0.7, so that the relay base station can be guaranteed to be mainly in the working state of sending the data packet.
In an optional embodiment, in a case that the target condition is determined to be the second target condition, determining the data transmission direction of the relay base station based on the determination result includes:
step S2070, determining the transmission direction as receiving the data packet from the macro base station under the condition that the determination result is used for indicating that the random number meets the second target condition;
step S2072, determining the transmission direction as sending the data packet stored in the relay base station to the user terminal when the determination result is used to indicate that the random number does not satisfy the second target condition.
In this embodiment, when the number m of data packets in the relay base station is far away from (far less than) the first preset threshold h, in order to ensure that the number m of data packets in the relay base station floats near the first preset threshold h, the working state of the relay base station needs to be mainly the received data packets, and at this time, it is determined whether the random number x is greater than or equal to the first preset threshold h, where the random number x is greater than or equal to the second preset threshold h
And when the random number is smaller than x, indicating the relay base station to send the data packet, otherwise, indicating the relay base station to receive the data packet.
Since the random number is randomly generated, x may be greater than
May also be less than
So that the number m of data packets stored in the relay base station is floated with the change of the random number x, but at this time, p can be preset2And p1X is less than
The probability of (2) is greater, so that the working state of the relay base station is mainly to transmit data packets.
For example, when p1＝0.8，p2When h is 0.5, h is 10 and m is 2, the formula
The value of (a) is equal to about 0.8, and the probability that x is greater than 0.8 is 0.2, and the probability that x is less than 0.8 is 0.8, so that the relay base station can be guaranteed to be mainly in the working state of receiving the data packet.

It should be noted that, the above modules may be implemented by software or hardware, and for the latter, the following may be implemented, but not limited to: the modules are all positioned in the same processor; alternatively, the modules are respectively located in different processors in any combination.
The present invention will be described with reference to specific examples.
As shown in fig. 4 and 5, assuming that the macro base station has K1000 data packets to send to the mobile user through the relay base station, the probability p that the channel between the macro base station and the relay base station successfully transmits one data packet is assumed to be10.8, probability p of successful transmission of one packet of data on the channel between the relay base station and the user20.5. Before transmission, let m be 0, n be 0, and a first preset threshold h be 10, where n is the number of packets received by the ue (corresponding to S501 in fig. 5).
In the first time slot, a random number x is randomly generated (corresponding to S502 in fig. 5), and x is assumed to be 0.312. Since m is 0<h is 10 (corresponding to S503 in fig. 5), we need to sum x with x
Is compared (corresponding to S508 in fig. 5). Due to the fact that
Obviously x is
Small, therefore, the relay base station will choose to receive the data packet from the macro base station (corresponding to S505 in fig. 5), otherwise the relay base station will choose to send one data packet to the user terminal (corresponding to S509 in fig. 5). If the packet is successfully received (corresponding to S506 in fig. 5), m is 0+1 is 1 (corresponding to S507 in fig. 5), and if the ue successfully receives a packet (corresponding to S511 in fig. 5), n is 0+1 is 1 (corresponding to S512 in fig. 5).
In the next time slot, the relay base station selects between receiving the data packet and sending the data packet according to the current buffer size m in the same way.
Let us assume that in the 30 th slot, we have m 15 and n 5. A random number x is randomly generated, assuming that x is 0.891. Due to m>h, we need to sum x with
Is compared (corresponding to S504 in fig. 5). Due to the fact that
Obviously x is
Larger, the relay base station will therefore choose to send one packet to the user (corresponding to S509 in fig. 5). If the user successfully receives the packet (corresponding to S506 in fig. 5), n-5 + 1-6 and m-15-1-14. Since n is<Since K is 1000, the user has not completed receiving all packets and transmission continues.
According to the above transmission method, when the users all receive 1000 packets, i.e., when n is 1000, the transmission ends.
