In the embodiment of the present invention, when the channel environment for transmitting the air interface frame becomes poor or the channel environment for transmitting the air interface frame becomes good, the transmitting end of the microwave device needs to adjust the modulation mode or the symbol rate for transmitting the air interface frame.

102. And the microwave equipment sending end determines at least three symbol rates of the air interface frame according to the symbol rate before the air interface frame is adjusted and the symbol rate switching direction.

103. And the microwave equipment sending end sends an air interface frame to the microwave equipment receiving end through at least three symbol rates.

Wherein, the air interface frame carries service data.

For the embodiment of the present invention, the sending end of the microwave device needs to gradually adjust the symbol rate of the sent air interface frame until the symbol rate is adjusted to a preset symbol rate or until the channel condition of the transmitted air interface frame is stable.

104. And the receiving end of the microwave equipment receives the air interface frame sent by the sending end of the microwave equipment.

105. And the receiving end of the microwave equipment determines the symbol rate of the demodulation air interface frame.

For the embodiment of the present invention, an air interface frame includes a frame header portion and a data portion. The service data is carried in the data portion. In the embodiment of the present invention, the receiving end of the microwave device receives the air interface frame sent by the sending end of the microwave device in real time, and after receiving the air interface frame sent by the sending end of the microwave device, the receiving end of the microwave device determines the symbol rate of the demodulated air interface frame according to the symbol rate information carried by the frame header part of the air interface frame.

106. And the receiving end of the microwave equipment demodulates the air interface frame according to the symbol rate of the demodulated air interface frame to obtain service data.

For the embodiment of the present invention, the receiving end of the microwave device demodulates the data portion of the received air interface frame according to the determined symbol rate of the demodulated air interface frame, and obtains the service data.

In the method for transmitting data according to the embodiment of the present invention, first, a sending end of a microwave device obtains a symbol rate switching direction, where the symbol rate switching direction includes: increasing the symbol rate of the transmitted air interface frame or reducing the symbol rate of the transmitted air interface frame, determining at least three symbol rates of the transmitted air interface frame according to the symbol rate before the adjustment of the air interface frame and the switching direction of the symbol rates, transmitting the air interface frame to a receiving end of the microwave equipment through the at least three symbol rates, wherein the air interface frame carries service data, receiving the air interface frame transmitted by a transmitting end of the microwave equipment by the receiving end of the microwave equipment, determining the symbol rate of a demodulated air interface frame, and finally demodulating the air interface frame by the receiving end of the microwave equipment according to the symbol rate of the demodulated air interface frame to obtain the service data. Compared with the prior art that the microwave equipment sends the transition frame first until the microwave equipment receiving end receives the transition frame, and the microwave equipment sending end sends the air interface frame carrying the service data, the embodiment of the invention sends the air interface frame carrying the service data to the microwave equipment receiving end through at least three determined symbol rates of the sent air interface frame, and the microwave equipment receiving end can determine and demodulate the symbol rate of the air interface frame according to the received air interface frame to obtain the service data, namely, the microwave equipment receiving end can always obtain the service data without sending the transition frame not carrying the service data first, and sends the air interface frame carrying the service data after the link is established to obtain the service data, thereby avoiding the interruption of the service data transmission.

The first indication information is used for indicating the sending end of the microwave equipment to adjust the symbol rate of the sending air interface frame.

201b, the microwave equipment receiving end sends second indication information to the microwave equipment sending end.

The second indication information carries a channel condition of a transmission air interface frame, and the second indication information is used for indicating a sending end of the microwave equipment to adjust a symbol rate of the transmission air interface frame.

For the embodiment of the present invention, the receiving end of the microwave device can firstly know the channel condition of the current transmission air interface frame, and send the indication information to the sending end of the microwave device according to the channel condition of the current transmission air interface frame, so as to indicate the sending end of the microwave device to adjust the symbol rate of the transmission air interface frame. In the embodiment of the invention, a receiving end of microwave equipment determines a symbol rate switching direction according to the channel condition of a current transmission air interface frame, and sends first indication information carrying the symbol rate switching direction to a sending end of the microwave equipment; or the microwave device carries the channel condition of the current transmission air interface frame to the second indication information, and sends the second indication information to the microwave device sending end, so that the microwave device sending end determines the symbol rate switching direction according to the channel condition of the current air interface frame carried in the second indication information.

If the channel condition of the current transmission air interface frame is poor, the sending end of the microwave equipment determines the switching direction of the symbol rate to reduce the symbol rate of the sending air interface frame; if the channel condition of the current transmission air interface frame becomes good, the sending end of the microwave equipment determines the switching direction of the symbol rate to increase the symbol rate of the sending air interface frame.

202b, the sending end of the microwave device receives the second indication information sent by the receiving end of the microwave device, and determines the symbol rate switching direction according to the second indication information.

And the second indication information carries the channel condition of the transmission air interface frame.

For the embodiment of the present invention, the receiving end of the microwave device sends the symbol rate switching direction to the sending end of the microwave device through the first indication information, or sends the channel condition of the currently transmitted air interface frame to the receiving end of the microwave device through the second indication information, so that the sending end of the microwave device can obtain the channel condition of the currently transmitted air interface frame, and can adjust the symbol rate of the sent air interface frame according to the channel condition of the currently transmitted air interface frame, so as to prevent the sending end of the microwave device from still sending the air interface frame according to the previous symbol rate, which causes the receiving end of the microwave device to be unable to demodulate the air interface frame, thereby further avoiding service transmission interruption.

Another possible implementation manner of the embodiment of the present invention is, on the basis as shown in fig. 2, that step 201a, the receiving end of the microwave device sends the first indication information carrying the symbol rate switching direction to the sending end of the microwave device, or step 201b, the receiving end of the microwave device sends the second indication information to the sending end of the microwave device, and before this, step 301 and step 305 shown in fig. 3 are further included.

301. And the microwave equipment receiving end sends modulation mode switching indication information to the microwave equipment sending end.

The modulation mode switching indication information is used for indicating the microwave equipment sending end to adjust the modulation mode of the sending air interface frame.

And the modulation mode switching indication information carries a modulation mode switching indication direction.

For the embodiment of the present invention, the modulation mode switching indication information sent by the microwave device receiving end to the microwave device sending end may carry the modulation mode switching direction, or only carry the channel condition of the currently transmitted air interface frame.

For the embodiment of the present invention, the receiving end of the microwave device may also send modulation mode switching indication information carrying the channel condition of the currently transmitted air interface frame to the sending end of the microwave device, and the sending end of the microwave device may determine the modulation mode switching direction according to the channel condition of the currently transmitted air interface frame carried in the modulation mode switching indication information, and adjust the modulation mode for sending the air interface frame according to the modulation mode switching direction and the modulation mode switching direction.

For the embodiment of the present invention, when the weather condition becomes good, that is, the channel condition of the currently transmitted air interface frame becomes good, the microwave device transmitting end or the microwave device receiving end determines that the modulation mode switching direction is the increased modulation mode; and when the weather condition becomes worse, namely the channel condition of the current transmission air interface frame becomes worse, the microwave equipment sending end or the microwave equipment receiving end determines that the modulation mode switching direction is the reduced modulation mode.

303. And the microwave equipment sending end adjusts the modulation mode of the air interface frame according to the switching direction of the modulation mode.

For the embodiment of the present invention, if the switching direction of the modulation mode is to increase the modulation mode of transmitting the air interface frame, step 303 may specifically include step 303 a; if the switching direction of the modulation mode is to decrease the modulation mode of sending the air interface frame, step 303 may specifically include step 303 b.

303b, the microwave device sending end gradually decreases the modulation mode of sending the air interface frame according to the switching direction of the modulation mode until the modulation mode of sending the air interface frame is adjusted to the preset modulation mode.

For the embodiment of the present invention, when the channel condition of the currently transmitted air interface frame becomes poor, the sending end of the microwave device first gradually decreases the modulation mode for sending the air interface frame until the modulation mode for sending the air interface frame is adjusted to the preset modulation mode, and then gradually decreases the symbol rate for sending the air interface frame. In the embodiment of the present invention, the preset modulation mode is any modulation mode, and when the modulation mode for sending the air interface frame is adjusted to the preset modulation mode, the channel condition for transmitting the air interface frame can be ensured to be stable.

304. And the receiving end of the microwave equipment receives the air interface frame sent by the sending end of the microwave equipment.

The air interface frame carries the modulation mode switching indication direction and the service data.

305. And the receiving end of the microwave equipment determines the modulation mode of the demodulation air interface frame according to the modulation mode switching indication direction, and demodulates the air interface frame according to the modulation mode of the demodulation air interface frame to obtain the service data.

For the embodiment of the present invention, the air interface frame includes: the Preamble header indication information, the first indication information or the second indication information, at least one set of pilot (global name: pilot) and Payload (Payload), the modulation mode switch indication information, and the Dummy (global name: Dummy) padding bit, as shown in fig. 4.

For the embodiment of the present invention, the receiving end of the microwave device receives the air interface frame sent by the sending end of the microwave device, determines the modulation mode of the demodulated air interface frame according to the modulation mode switching direction carried by the frame header part of the air interface frame, and demodulates the air interface frame according to the modulation mode to obtain the service data.

For the embodiment of the present invention, the modulation mode switching indication information carrying the modulation mode switching direction is sent to the microwave equipment sending end through the microwave equipment receiving end, so that the microwave equipment sending end adjusts the modulation mode for sending the air interface frame according to the modulation mode switching indication direction, and the problem that the microwave equipment sending end still sends the air interface frame according to the previous modulation mode, so that the microwave equipment receiving end cannot receive and demodulate the air interface frame is avoided, and thus the microwave equipment receiving end can receive and demodulate the air interface frame sent by the microwave equipment sending end, and further service transmission interruption can be avoided.

Another possible implementation manner of the embodiment of the present invention is, on the basis shown in fig. 3, that step 201a is performed by the microwave device receiving end to send first indication information carrying a symbol rate switching direction to the microwave device sending end, or step 201b is performed by the microwave device receiving end to send second indication information to the microwave device sending end, and before this, the method further includes step 501 shown in fig. 5, step 103 is performed by the microwave device sending end to send an air interface frame to the microwave device receiving end through at least three symbol rates, and before this, the method further includes step 502 shown in fig. 5, step 105 is performed by the microwave device receiving end to determine a symbol rate of a demodulated air interface frame, and specifically includes step 503 shown in fig. 5.

501. The receiving end of the microwave equipment configures a first symbol rate value and a second symbol rate value.

The first symbol rate value is the maximum value or the minimum value of the symbol rate of the sending empty frame, and the second symbol rate value is the change value of the symbol rate of each sending empty frame.

Specifically, the second symbol rate value is a ratio of the first symbol rate value to the number of frames of the air interface frame, and the second symbol rate value is smaller, that is, the sending end of the microwave device uniformly and slowly adjusts the symbol rate of the air interface frame.

Specifically, the symbol rate of the transmitted air interface frame must meet the requirement for the symbol rate in the spectrum template, so as to avoid that the symbol rate of the transmitted air interface frame exceeds the requirement of the spectrum template, causes interference with other devices, and affects communication, and therefore the maximum value of the transmitted air interface frame needs to be limited.

502. And the sending end of the microwave equipment switches the direction of the symbol rate and adds the symbol rate to an air interface frame.

503. And the receiving end of the microwave equipment determines the symbol rate of the demodulation air interface frame according to the symbol rate switching direction, the first symbol rate value and the second symbol rate value.

For the embodiment of the present invention, the microwave device sending end and the microwave device receiving end are preconfigured with the first symbol rate value and the second symbol rate value, the microwave device sending end may send the indication information only carrying the symbol rate switching direction to the microwave device receiving end, and the microwave device receiving end may determine the symbol rate for demodulating the air interface frame according to the symbol rate switching direction carried in the indication information and the first symbol rate value and the second symbol rate value preconfigured by the microwave device receiving end.
