Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] An embodiment of the present invention provides a method for transmitting data packets. see figure 1 , the method includes the following.

[0048] 101. Calculate the retransmission rate of the data packet according to the number of times the data packet is sent and the number of times the data packet is retransmitted in the first cycle;

[0049] 102. If the calculated retransmission rate of the data packet is greater than or equal to the preset first retransmission rate, reduce the air interface modulation coding order;

[0050] 103. Send the data packet according to the air interface modulation and coding order in a second period, where the second period is the next period closest to the first period.

[0051] In the embodim...

Abstract

Provided are a method and device for transmitting a data packet, which relate to the field of communications. The method comprises: according to the number of times of transmitting a data packet and the number of times of retransmitting the data packet within a first cycle, calculating the retransmission rate of the data packet; if the retransmission rate of the data packet is greater than or equal to a preset first retransmission rate, reducing an air interface modulation and encoding order; and within a second cycle, transmitting the data packet according to the air interface modulation and encoding order, the second cycle being the next cycle closest to the first cycle. The device comprises: a calculation unit, a reduction unit and a transmission unit. By means of the present invention, an appropriate air interface modulation and encoding order is obtained according to the retransmission rate of a data packet, and the data packet is transmitted according to the air interface modulation and encoding order, so that the probability of transmission failure of the data packet can be reduced, thereby saving air interface resources, and improving the efficiency of transmitting the data packet.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for transmitting data packets. Background technique [0002] The air interface technology is a key technology in the communication system, for example, during the transmission of the data packet, the data packet can be transmitted through the air interface. [0003] At present, the specific process of transmitting data packets through the existing technology is: the first terminal encodes the data packets to be sent according to the air interface modulation coding order, and sends the encoded data packets to the second terminal. If it fails, the first terminal will re-encode the data packet to be sent according to the air interface modulation coding order and send it until the sending is successful or the link is released. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art...
