[0031] Such as figure 1 As shown, the embodiment of the present invention provides a data message transmission method, which is applied to a data message transmission device, including:

[0032] Step 11, determining a first sending rate and a first sending power for sending a first preset number of data packets.

[0033] It should be noted that, each time the transmission device of the data message sends data, it will select a modulation method to modulate the data packet. In this case, each data transmission will correspond to a transmission rate. It is noted that the transmission rate is preset, and in order to ensure the normal transmission of data, a transmission power will be set at each transmission rate, and the transmission device of the data message will transmit data according to the transmission power , it should be noted that the corresponding relationship between the transmission rate and the transmission power needs to be preset and stored in the data packet tra...

[0080] Such as Figure 6 and Figure 7 As shown, the transmission device of the data message in the embodiment of the present invention includes:

[0081] A determination module 601, configured to determine a first transmission rate and transmission power for transmitting a first preset number of data packets;

[0082] The first acquiring module 602 is configured to send a first preset number of data packets to the peer device according to the first sending rate and transmitting power, and acquire a first bit error rate for data sending;

[0083] The second obtaining module 603 is configured to obtain the second sending rate of the pre-sent data message after sending the first preset number of data messages;

[0084] A first adjustment module 604, configured to reduce the transmission power if the second transmission rate is the same as the first transmission rate and the first bit error rate is less than a first preset threshold;

[0085] The first sending module 605 is co...

[0101] Such as Figure 8 Shown is a structural block diagram of a device for transmitting data packets according to an embodiment of the present invention. The application entity of the data packet transmission method of the present invention will be specifically described below in conjunction with this figure.

[0102] Such as Figure 8 The shown data packet transmission apparatus 800 includes: at least one processor 801 , a memory 802 , at least one network interface 804 and a user interface 803 . The various components in the data message transmission device 800 are coupled together through the bus system 805 . It can be understood that the bus system 805 is used to realize connection and communication between these components. In addition to the data bus, the bus system 805 also includes a power bus, a control bus and a status signal bus. But for clarity, in Figure 8 The various buses are denoted as bus system 805 in FIG.

[0103] Wherein, the user interface 803 may...

Abstract

The invention provides a data message transmission method and device. The transmission method comprises the steps of determining a first sending rate and a transmitting power for sending the first preset number of data messages; sending the first preset number of data messages to an opposite end device according to the first sending rate and the transmitting power, and obtaining a first data sending bit error rate; after the first preset number of data messages are sent completely, obtaining a second sending rate for sending the data messages; if the second sending rate is the same to the second sending rate and the first bit error rate is smaller than a first preset threshold value, reducing the transmitting power; and continuing to send the data messages to the opposite end device according to the reduced transmitting power and the second sending rate. Under the condition that the sending rate is unchanged, when the data sending bit error rate is smaller than the preset value, the transmitting power of the data is reduced, thereby reducing the data sending power consumption when the bit error rate is relatively low.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data message transmission method and device. Background technique [0002] With the popularity of smart phones, Wi-Fi has become an indispensable part of people's lives, and social entertainment is ubiquitous. Therefore, people have higher requirements for the performance and power consumption of Wi-Fi. [0003] Before the wireless device leaves the factory, it will set the power corresponding to the rate for various specific modulation methods under the condition that the radio frequency index meets certain standard requirements, and finally generate a table corresponding to the rate set and the transmission power. When the wireless device sends data, A common practice is to find out the transmission power corresponding to the transmission rate according to the currently selected transmission rate, and use the transmission power to control the transmission of data. ...
