Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be noted that, in the description and claims of the present application and in the above drawings, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. . It is to be understood that the data so used may be interchanged under appropriate circumstances such that the embodiments of the application described herein can be practiced in sequences other than those illustrated or described herein. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or server comprising a series of steps or elements is not necessarily limited to those steps or elements expressly listed, Rather, other steps or units not expressly listed or inherent to the process, method, product or apparatus may be included.

Please refer to FIG. 1. FIG. 1 is a scene diagram of a data transmission method provided by an embodiment of the present application. Specifically, as shown in FIG. 1, in this scenario, the near-end device 101 communicates with the far-end device 102 by using an information frame. The information frame includes a transport block, and the time domain position of the transport block corresponds to a bit (bit) of the data stream.

Wherein, the near-end device 101 refers to a cellular communication device that is closer to the base station 103 than the far-end device 102; The distance between the remote device 102 and the base station 103 is smaller than the distance between the remote device 102 and the base station 103; the near-end device 101 may also be referred to as the host, and the remote device 102 may be referred to as the slave.

Before the near-end device 101 communicates with the far-end device 102, the time synchronization between the near-end device 101 and the far-end device 102 needs to be performed, which specifically includes the following two processes:

The first process: the near-end device performs a cell search process to read the time synchronization information of the first cell in the process of the cell search process, and adjusts the near-end device 101 to the time synchronization information of the first cell according to the time synchronization information of the first cell Time synchronization with the base station 103 to which the first cell belongs.

The first cell refers to the cell with the largest RSRP (Reference Signal Receiving Power) searched by the near-end device 101 by performing the cell search process, and the RSRP of the first cell needs to be within the first RSRP threshold within the range to ensure that the near-end device 101 can communicate with the network side normally through the first cell. The time synchronization information may be different in different communication standards and communication systems; in the LTE (Long Term Evolution, Long Term Evolution) communication system, the time synchronization information of the first cell refers to the MIB (Master Information Block, master message of the first cell) piece).

The remote device 102 uses the same method as the near-end device 101 to adjust the time of the remote device 102 to synchronize with the base station 103 in the second cell, which is not repeated here. The second cell refers to the cell with the largest RSRP searched by the remote device 102 by performing the cell search process, and the RSRP of the second cell needs to be within the second RSRP threshold range to ensure that the remote device 102 can pass the second cell. The cell communicates normally with the network side.

The near-end device 101 and the far-end device 102 also need to exchange information to determine whether the base station 103 to which the first cell belongs and the base station to which the second cell belongs are the same base station, and whether the first cell and the second cell are the same cell ; If the base station 103 to which the first cell belongs and the base station to which the second cell belongs are the same base station, and the first cell and the second cell are the same cell, it can be determined that the near-end device 101 and the far-end device 102 are time-synchronized; if If the base station 103 to which the first cell belongs and the base station to which the second cell belongs are not the same base station, and/or the first cell and the second cell are not the same cell, it is determined that the time between the near-end device 101 and the far-end device 102 is not synchronized, The second cell is updated, the remote device 102 is adjusted to be time-synchronized with the base station 103 to which the updated second cell belongs, and the near-end device 101 exchanges information with the remote device 102. The remote device 102 is time synchronized.

In the embodiment of the present application, since the clock source of the near-end device 101 is different from the clock source of the base station to which the first cell belongs, and the clock source of the far-end device 102 is different from the clock source of the base station to which the second cell belongs, in the first process After that, time synchronization deviation and frequency deviation (frequency deviation) may occur between the near-end device 101 and the far-end device 102 and the corresponding base stations. Therefore, the time synchronization process between the near-end device 101 and the far-end device 102 also includes the second process. .

The second process: after the first process, the near-end device receives the (frequency) signal of the base station (to which the first cell belongs), and according to the signal of the base station, obtains the time synchronization deviation between the near-end device 101 and the base station and the Frequency offset (frequency offset), corrects the time synchronization offset and frequency offset between the near-end device 101 and the base station to which the first cell belongs, so that the near-end device 101 maintains time synchronization with the base station to which the first cell belongs. The near-end device 101 communicates with the far-end device 102 by using the information frame allocated to the near-end device; wherein, the information frame includes a transmission block, and the time domain position corresponding to the information frame includes the time domain position corresponding to the transmission block, the third time domain position, and the third time domain position. domain position and fourth time domain position, the time domain position corresponding to the transmission block includes the first time domain position and the second time domain position; the third time domain position is located before the time domain position corresponding to the transmission block; the fourth time domain position is located at The third time domain position is between the time domain position corresponding to the transport block, and/or the fourth time domain position is located after the time domain position corresponding to the transport block. The near-end device 101 receives the (frequency) signal of the base station 103 at the third time domain position, for example: the near-end device 101 receives the public network frequency signal in the LTE communication scenario at the third time domain position; The fourth time domain position calculates the time synchronization offset and frequency offset (frequency offset) between the near-end device 101 and the base station 103 according to the signal of the base station 103, and corrects the time synchronization offset and frequency offset between the near-end device 101 and the base station 103 to make The near-end device 101 maintains time synchronization with the base station 103 .

The remote device 102 receives the (frequency point) signal of the base station (to which the second cell belongs), obtains the time synchronization offset and frequency offset between the remote device 102 and the base station according to the signal of the base station, and compares the relationship between the remote device 102 and the base station. The time synchronization offset and frequency offset of the base station to which the second cell belongs are corrected, so that the remote device 102 maintains time synchronization with the base station to which the second cell belongs. The far-end device 102 communicates with the near-end device 101 using the information frame allocated to the far-end device; the sub-frame structure of the information frame allocated to the far-end device 102 and the sub-frame structure of the information frame allocated to the near-end device 101 same.

In this embodiment of the present application, the near-end device 101 and the far-end device 102 can communicate through wired communication, for example, through cables, optical fibers, or through wireless communication; if the near-end device 101 When communicating with the remote device 102 through wireless communication, the information frame is a wireless frame.

Specifically, as shown in FIG. 2, the communication period of the radio frame is 160ms, and each radio frame has the 0th subframe to the 9th subframe There are 10 subframes such as frame, and each radio frame corresponds to the time domain position of 10ms; in each radio frame, the time domain position corresponding to the transmission block is the time domain position corresponding to the second subframe to the seventh subframe, and the third time domain position The domain position is a time domain position corresponding to the 0th subframe, and the fourth time domain position is a time domain position corresponding to at least one of the first subframe, the eighth subframe, and the ninth subframe.

The fact that the third time domain position is located before the time domain position corresponding to the transmission block means that the third time domain position is located before the time domain position corresponding to the transmission block in the same information frame, for example: in the 0th subframe in the same radio frame The frame precedes the 2nd subframe (to the 7th subframe).

The fact that the fourth time domain position is located between the third time domain position and the time domain position corresponding to the transport block means that the fourth time domain position is located in the time domain corresponding to the transport block in the third time domain position in the same information frame Between positions, for example, the first subframe is located between the 0th subframe and the second subframe (to the 7th subframe) in the same radio frame.

The fact that the fourth time domain position is located after the time domain position corresponding to the transport block means that the fourth time domain position is located after the time domain position corresponding to the transport block in the same information frame, for example: in the same information frame In the radio frame, the 8th subframe and the 9th subframe are located after (the 2nd subframe to) the 7th subframe.

It should be noted that the communication period of the radio frame is not limited to 160 ms as shown in FIG. 2 , and the communication period of the radio frame may also be set to other time lengths. The near-end device 101 and the far-end device 102 can receive the signal of the base station 103 in a wired or wireless manner. The second process can also be performed after the near-end device 101 communicates with the far-end device 102. For example, after the near-end device 101 and the far-end device 102 communicate through the transmission block of the first radio frame, The 8th subframe and/or the 9th frame of the first radio frame calculates the time synchronization offset and frequency offset (frequency offset) between the near-end device 101 and the base station 103 according to the signal of the base station 103, and calculates the time synchronization offset and frequency offset. Modified to keep the near-end device 101 in time synchronization with the base station 103 . The communication between the near-end device 101 and the far-end device 102 can be specified to use the first wireless frame in each communication cycle, and one or more wireless frames can also be specified to be used for the near-end device 101 in each communication cycle as required. The communication with the remote device 102 is not repeated here.

The transmitting end device determines the transmission power corresponding to the transmission block in the information frame according to the bit value of the data stream; and transmits the data signal of the transmission block according to the determined transmission power, for example, periodically transmits the transmission by means of broadcasting. The data signal of the block; the receiving end device determines the bit value of the data stream according to the RSSI (Received Signal Strength Indication, received signal strength indication) corresponding to the data signal.

Specifically, as shown in Figure 2, each subframe in the transmission block can be divided into 15 OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) symbols, and each subframe no longer has a CP (Cyclic Prefix, cyclic prefix), Each OFDM symbol uses 2048Ts, and each transport block shown in Figure 2 can transmit 90 bits of information. The time domain position of the transport block corresponds to the bit of the data stream means that the OFDM symbol in the transport block corresponds to the bit of the data stream, and the determination of the transmit power corresponding to the transport block may be the determination of each transmission power in the transport block. The transmit power corresponding to the OFDM symbol.

It should be noted that the remote device 102 is not limited to one remote device 102 shown in FIG. 1 , but may also be multiple remote devices 102 . The near-end device 101 and the far-end device 102 may be Modem (modem) terminals, and may also be other types of cellular communication terminals, which are not limited herein. The near-end device 101 and the far-end device 102 are not limited to receiving signals from the same base station 103 shown in FIG. 1 , but they can also receive signals from different base stations. The signal of the base station is used for time synchronization, time synchronization deviation and frequency deviation correction, then the near-end device 101 and the far-end device 102 cannot achieve time synchronization; if the near-end device 101 and the far-end device 102 do not have time synchronization, then The receiving end device cannot accurately receive the data stream sent by the sending end device.

The value, for example: receiving the data signal, and determining the bit value of the data stream corresponding to the transport block in the information frame according to the RSSI corresponding to the received signal strength of the data signal.

S503: The transmitting end device determines the transmit power corresponding to the transport block in the first information frame according to the bit value of the data stream.

The sending end device communicates with the receiving end device by using a first information frame, that is, the first information frame is used for the sending end device to communicate with the receiving end device; the first information frame includes a transmission block, and the The time domain position of the transport block corresponds to the bit (bit) of the data stream, where the data stream is a plurality of consecutive pieces of data to be sent by the sender device to the receiver device.

and/or: determining the transmit power corresponding to the second time domain position as the second transmit power; the second time domain position refers to the difference between the transmission block of the first information frame and the bit value of 0 in the data stream; the corresponding time domain location.

Specifically, as shown in FIG. 2, the transmit power corresponding to the OFDM symbol corresponding to the bit value of 1 in the data stream in the transmission block of the first information frame is determined as the first transmit power; the transmission power of the first information frame is determined as the first transmit power. The transmit power corresponding to the OFDM symbol corresponding to the bit valued as 0 in the data stream in the block is determined as the second transmit power.

In this embodiment of the present application, the first transmit power is greater than the second transmit power; therefore, the RSSI of the data signal sent with the first transmit power received by the receiving end device is greater than the RSSI of the data signal sent with the second transmit power RSSI.

In the embodiment of the present application, the first N bits of the data stream are flag bits, and N is a positive integer; the flag bits are used to identify the data stream.

For example, the marker bit includes two bits, and the values of the two bits are 10 in turn; therefore, the transmit power corresponding to the first bit (the value of 1) in the marker bit can be determined as the first transmit power , and the transmit power corresponding to the second bit bit (valued as 0) is determined as the second transmit power.

In the embodiment of the present application, the last Q bits of the data stream are CRC (Cyclic Redundancy Check, cyclic redundancy check) codes, which are used for the receiving end device to perform a cyclic redundancy check on the bit value of the data stream. , to determine whether the bit value of the data stream is valid, and Q is a positive integer.

In this embodiment of the present application, an 8-bit CRC code can be used, that is, the last 8 bits of the data stream are the CRC code, and the 8-bit CRC code can be stored in the last 8 OFDMs of the seventh frame in the radio frame shown in FIG. 2 . symbol.

S504: The transmitting end device sends the data signal of the transport block according to each determined transmit power, so that the receiving end device indicates the RSSI according to the received signal strength corresponding to the data signal, and determines the bit value of the data stream. value.

Specifically, the transmitting end device continuously transmits multiple data signals of the transmission block according to the determined transmission powers, for example, continuously transmits M data signals of the transmission block, where M is a positive integer.

The data signal of the transport block may be a modulated signal modulated according to a preset modulation method. The preset modulation mode can be set according to the communication standard and communication standard used for data transmission between the transmitting end device and the receiving end device; for example: if the transmitting end device and the receiving end device use LTE (Long Term Evolution, Long Term Evolution) communication technology for data transmission, the data signal of the transmission block can be in accordance with QPSK (Quadrature Phase Shift Keying, quadrature phase shift keying), 16QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation) and 64QAM (Quadrature Amplitude Modulation, phase A signal modulated by one or more modulation methods in quadrature amplitude modulation); accordingly, if the transmitting end device and the receiving end device use 2G (2rd-Generation Wireless Telephone Technology, the second generation of wireless communication technology), 3G (3rd-Generation, third-generation wireless communication technology) or NR (New Radio, new air interface) communication technology for data transmission, the data signal of the transmission block may be performed according to the modulation method corresponding to the 2G, 3G or NR communication technology. Modulated modulated signal.

The data signal of the transport block may also be a monophonic signal, that is, a pure sinusoidal signal of a single frequency. As shown in FIG. 2 , according to each determined transmit power, the transmitting end device can continuously transmit a single tone signal of 6 ms. After receiving the data signal that is a modulated signal or a single tone signal, the receiving end device does not need to perform demodulation processing on the data signal or the single tone signal, but obtains the bits of the data stream according to the RSSI of the data signal.

In this embodiment of the present application, the sending of the data signal of the transport block according to the determined transmit powers includes the following steps:

S5041: The transmitting end device turns on the radio frequency function of the transmitting end device at the fourth time, so that the transmitting end device is in a state that is allowed to send data signals, and adjusts the APC (Automatic Power Control) GAIN (Gain) of the transmitting end device ) is set to the minimum value allowed by APC GAIN.

The fourth time is located before the start position of the time domain position corresponding to the transmission block and is a fourth time period from the start position of the time domain position corresponding to the transmission block.

In the embodiment of the present application, enabling the radio frequency function of the transmitting end device in advance may reserve a buffering time for the normal use of the radio frequency function, and the fourth time may be located in the first subframe shown in FIG. 2 .

Please refer to FIG. 7. FIG. 7 is a schematic diagram of a bit value corresponding to a state of an APC GAIN and a data signal according to an embodiment of the present application. Specifically, as shown in FIG. 7 , t0 in FIG. 7 is the fourth time, and t2 is the start position of the time domain position corresponding to the transport block, that is, the start position of the time domain position corresponding to the first bit of the data stream. In Figure 7, CW Amplitude represents the continuous wave signal amplitude (Continuous Wave).

S5042: The transmitting end device opens the APC GAIN corresponding to the transmitting power corresponding to the first bit value of the data stream at the third time;

The third time is located before the start position of the time domain position corresponding to the first bit of the data stream and is a third time period away from the start position.

In the embodiment of the present application, the APC GAIN corresponding to the transmission power corresponding to the first bit value of the data stream is opened in advance, so as to reserve the buffering time for the normal use of the APC GAIN of the terminal, and the third time can be located in Fig. 2 in the first subframe, and the third time is located after the fourth time.

Specifically, as shown in FIG. 7 , the terminal turns on the APC GAIN corresponding to the second transmit power corresponding to the second time domain position between t ₂ and t ₃ at t ₁ , t ₁ is located before t ₂ , and t ₁ is located at t ₀ after.

S5043: At the first time domain position, the transmitting end device turns on the automatic power control APC gain GAIN corresponding to the first transmit power, and transmits a data signal at the first transmit power;

And/or: at the second time domain position, the APC GAIN corresponding to the second transmission power is turned on, and the data signal is sent at the second transmission power.

It should be noted that when the automatic power control APC gain GAIN corresponding to the first transmission power is turned on, the APC GAIN corresponding to the second transmission power needs to be turned off, so as not to cause interference to the generation of the first transmission power, so that the data signal cannot be accurately , effectively transmit with the first transmission power; when the APC GAIN corresponding to the second transmission power is turned on, it is necessary to close the APC GAIN corresponding to the first transmission power, so as to avoid causing interference to the generation of the second transmission power, so that the data signal cannot be accurately, The effective second transmit power is transmitted.

Specifically, as shown in FIG. 7 , the data signal corresponding to the bit value of 1 corresponds to the first time domain position, and the data signal corresponding to the bit value of 0 corresponds to the second time domain position.

In this embodiment of the present application, the transmit power corresponding to the transport block in the first information frame is generated by using APC GAIN, and there is no need to configure a PA (Power Amplifier, power amplifier) on the transmitting end device, which reduces the difference between the transmitting end device and the receiving end device. The hardware cost of the end device.

In the embodiment of the present application, the enabling of the automatic power control APC gain GAIN corresponding to the first transmit power at the first time domain position includes:

If the previous time domain position of the first time domain position is the second time domain position, turn on the APC GAIN corresponding to the first transmit power at the first time;

Wherein, the first time is located after the starting position of the first time domain position and is a first duration away from the starting position of the first time domain position.

The first time is located between the start position and the end position of the first time domain position, and the first duration is less than the time duration of the first time domain position.

In this embodiment of the present application, after the automatic power control APC gain GAIN corresponding to the first transmit power is turned on, if the next time domain position of the first time domain position is the second time domain position, then Turn off the APC GAIN corresponding to the first transmit power at the second time;

Wherein, the second time is located before the end position of the first time domain position and is a second time period away from the end position of the first time domain position.

The second time is located between the start position and the end position of the first time domain position, and the second duration is less than the time duration of the first time domain position.

The RSSI value corresponding to each time domain position (each OFDM symbol) corresponds to the maximum RSSI value corresponding to the time domain position. Therefore, it is necessary to ensure that the transmit power corresponding to the second time domain position has no other valid signals. Based on this, for the two cases where the previous bit of the bit valued as 1 in the data stream is 0 and the next bit of the bit valued as 1 in the data stream is 0, set the transmission Power to do special treatment.

Specifically, for the value of the previous bit of the bit value of 1 in the data stream, the value of the previous bit is 0, even if the first time domain position corresponding to the bit value of 1 is reached, the first time will be delayed to open the first time. The APC GAIN corresponding to the transmit power can prevent the APC GAIN corresponding to the first transmit power from impacting the second time domain position corresponding to the previous bit with a value of 0, resulting in the receiving end device receiving the corresponding second time domain position. The RSSI of the data signal corresponds to the first transmission power.

For the next bit of the bit valued as 1 in the data stream, the value of the next bit is 0. Before reaching the second time domain position corresponding to the bit valued as 0, the APC GAIN corresponding to the first transmission power should be closed in advance. , to prevent the APC GAIN corresponding to the first transmit power from impacting the second time domain position corresponding to the latter bit with a value of 0, resulting in the RSSI of the data signal corresponding to the second time domain position being received by the receiving end device and the second time domain position. A transmit power corresponds.

Specifically, as shown in FIG. 7 , the first time domain position between t ₄ and t ₆ is the second time domain position between t ₃ and t ₄ . Therefore, the first time domain position is turned on at t 5 , which is the first time period from t ₄ . The APC GAIN corresponding to the transmit power, t ₅ is located after t ₄ ; the first time domain position between t ₆ and t ₈ is followed by the second time domain position between t ₈ and t _9. Therefore, at the distance t ₈ The APC GAIN corresponding to the first transmit power is turned off at t ₇ of two durations, and t ₇ is located before t ₈ .

In this embodiment of the present application, if the previous time domain position and the next time domain position of the current first time domain position (the corresponding bit value is 1) are also the first time domain position (the corresponding bit value is 1) , the APC GAIN corresponding to the first transmission power is kept in the open state from the starting position of the current first time domain position to the end position of the current first time domain position, and the APC GAIN corresponding to the second transmission power is kept in the closed state .

In the embodiment of the present application, if the previous time domain position and the next time domain position of the current second time domain position (the corresponding bit value is 0) are also the second time domain position (the corresponding bit value is 0) , the APC GAIN corresponding to the second transmission power is kept in the open state from the starting position of the current second time domain position to the end position of the current second time domain position, and the APC GAIN corresponding to the first transmission power is kept in the closed state .

S5044: The transmitting end device turns off the radio frequency function of the transmitting end device at the fifth time, and sets the APC GAIN of the transmitting end device to the minimum value allowed by the APC GAIN.

The fifth time coincides with the end position of the time domain position corresponding to the last bit of the data stream.

It should be noted that the time lengths of the first, second, third and fourth durations may be the same or different, and the durations of the first, second, third and fourth durations can be passed through RF (Radio Frequency, radio frequency) NV (Native Value, local parameter value) configuration of the sender device.
