[0027] The signal transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0028] As shown in FIG2 , an embodiment of the present application provides a signal transmission method 200 , which can be executed by a communication device. In other words, the method can be executed by software or hardware installed in the communication device. The method includes the following steps.

[0029] S202: The first communication device sends a first signal to the second communication device;

[0032] In one embodiment, the first communication device can be a read / write device, a handheld or fixed device that reads (and sometimes writes) information from a transponder. It can also be a device that communicates with the transponder, such as a terminal, a base station, or a device with read / write capabilities, such as a reader / writer.

RFID technology can be categorized as active, passive, and semi-active. Passive tags can also be referred to as passive IoT devices.

Because the transponder's energy can be derived from the environment, such as ambient RF energy, thermal energy, wind energy, kinetic energy, etc., it can also be referred to as an ambient IoT. Therefore, the transponder can also be considered a terminal, or a terminal device.

[0033] In one embodiment, the first communication device may be a network side device, and the second communication device may be a terminal.

[0034] In a specific embodiment, the first communication device is a reading and writing device (Reader), and the second communication device is a Tag. The Reader can send a first signal to the Tag, and the Tag receives the first signal; wherein the Reader can be a terminal or a network side device (such as an access network device), etc.

[0035] In one embodiment, the modulation mode of the first signal may include, but is not limited to, OOK modulation, amplitude shift keying (ASK) modulation, frequency shift keying (PSK) modulation, or minimum frequency shift keying (MSK) modulation. The above-mentioned OOK modulation includes, for example, OOK1 modulation, OOK4 modulation, etc. The above-mentioned ASK modulation includes, for example, DSB-ASK modulation, SSB-ASK modulation, or PR-ASK modulation.

[0036] The following step may also be included before S202: the first communication device generates a first signal based on the above modulation mode. Optionally, signal parameters of the first signal corresponding to different modulation modes may be (partially) the same or (partially) different.

[0037] After S202, the following steps may be further included: the second communication device demodulates the received first signal using a demodulation technology corresponding to the above modulation method. The above demodulation technology may be envelope detection, coherent demodulation, incoherent demodulation, etc.

[0038] Optionally, the first signal includes an on signal and an off signal; wherein the on signal may also be referred to as an on pulse, a 1 signal, a 1 pulse, or a high level, and the off signal may also be referred to as an off pulse, a 0 signal, a 0 pulse, or a low level. It is understood that the two signals included in the first signal in this application essentially refer to signals with different characteristics, and the different characteristics may include, but are not limited to, different information carried, signal waveforms, and signal levels, such as carrying information bits "0" and "1".

[0039] In the signal transmission method provided in the embodiments of the present application, a first communication device transmits a first signal to a second communication device, and signal parameters of the first signal satisfy signal parameter specifications. By controlling the signal parameters of the first signal to satisfy the signal parameter specifications, a receiving end (e.g., the second communication device) is facilitated in correctly receiving the first signal transmitted by a transmitting end (the first communication device), thereby improving communication performance.

[0040] The following will describe in detail how the signal parameters of the first signal meet the signal parameter index in a number of embodiments. It is understood that the embodiments described below can be implemented individually or in combination.

[0041] In one embodiment, the signal parameter includes a first parameter jitter, and the signal parameter of the first signal meeting a signal parameter indicator includes: the first parameter jitter of an on signal of the first signal does not exceed a first range.

[0042] The first parameter jitter includes, for example, amplitude jitter, voltage jitter, current jitter, or power jitter.

[0043] The first parameter jitter may also be referred to as the first parameter flatness.

[0044] In this embodiment, the jitter of the first parameter of the on signal of the first signal does not exceed the first range, which includes at least one of the following:

[0045] 1) The difference between the maximum value and the minimum value of the first parameter of the on signal of the first signal is within a first range, for example, the difference is within +X1 or -Y1 dB, and X1 and Y1 may be the same or different.

[0046] It should be noted that, in the embodiments of the present application, dB is used as an example of the power unit. Other units, such as amplitude, can be V or A (or mV, mA, without order of magnitude restriction, the same below), voltage can be V (or mV, etc.), current can be A (or mA, etc.), and power can be dB, dBm, W, mW, etc.

[0047] 2) A ratio between a maximum value and a minimum value of a first parameter of the on signal of the first signal is within a first range, for example, the ratio is within X1%.

[0048] 3) A difference between a value of the first parameter of the on signal of the first signal and a maximum value is within a first range, for example, the difference is within +X2 or -Y2 dB.

[0049] 4) A ratio between a value of a first parameter of the on signal of the first signal and a maximum value is within a first range, for example, the ratio is within X2%.

[0050] In a specific embodiment, the Reader can use OOK-1 modulation to generate a first signal and send the first signal, and the amplitude jitter, voltage jitter, current jitter or power jitter on the "1" pulse does not exceed a specified range (first range), for example, the difference between the amplitude, voltage, current or power of the "on" pulse and the maximum amplitude, voltage, current or power is within +X2 or -Y2dB, and the amplitude, voltage, current or power on the "0" pulse is 0.

[0051] The related art does not take into account the first parameter jitter of the on signal of the first signal, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the first parameter jitter of the on signal of the first signal to not exceed the first range, which is beneficial for the receiving end to correctly receive the first signal sent by the transmitting end and improve communication performance.

[0052] In one embodiment, the signal parameter includes PAPR, cubic metric or MPR, and the signal parameter of the first signal meeting the signal parameter index includes: the PAPR, cubic metric or MPR value of the on signal of the first signal does not exceed a first threshold.

[0053] The related art does not take into account the PAPR, cubic metric or MPR of the on signal of the first signal, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the PAPR, cubic metric or MPR value of the on signal of the first signal to not exceed the first threshold, which is beneficial for the receiving end to correctly receive the first signal sent by the transmitting end and improve communication performance.

[0054] The thresholds mentioned in various embodiments of the present application, such as the first threshold, the second threshold, ..., the tenth threshold, can all be predefined, network configured, device preconfigured, or determined based on the transmission power (of the first signal).

[0055] In one embodiment, the signal parameter includes a duty cycle, and the signal parameter of the first signal satisfies a signal parameter indicator including at least one of the following:

[0056] 1) The duty cycle of the on signal of the first signal exceeds a second threshold.

[0057] Optionally, the duty cycle of the on signal of the first signal is: the ratio of the time during which the value of the first parameter of the on signal is higher than the fourth threshold value to the first time within a first time, and the first time may be a sampling period.

[0058] 2) The duty cycle of the off signal of the first signal exceeds a third threshold.

[0059] Optionally, the duty cycle of the off signal of the first signal is: the ratio of the time during which the value of the first parameter of the off signal is lower than the fifth threshold within the second time to the second time, and the second time may be a sampling period.

[0060] The related art does not take the duty cycle of the first signal into consideration, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the duty cycle of the on signal of the first signal to exceed the second threshold and the duty cycle of the off signal of the first signal to exceed the third threshold, which is beneficial for the receiving end to correctly receive the first signal sent by the transmitting end and improve communication performance.

[0061] In one embodiment, the signal parameter includes a difference or ratio between an average first parameter value of the on signal and an average first parameter value of the off signal, and the signal parameter of the first signal satisfies at least one of the following signal parameter indicators:

[0062] 1) The difference between the average first parameter value of the on signal and the average first parameter value of the off signal of the first signal is greater than a sixth threshold value. For example, the difference between the average power value of the "on" signal and the average power value of the "off" signal is greater than X3dB.

[0063] 2) The ratio of the average first parameter value of the on signal to the average first parameter value of the off signal of the first signal is greater than a seventh threshold value. For example, the ratio of the average power value of the "on" signal to the average power value of the "off" signal is greater than X4%.

[0064] The related art does not consider the difference or ratio between the value of the average first parameter of the on signal and the value of the average first parameter of the off signal, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the difference between the value of the average first parameter of the on signal of the first signal and the value of the average first parameter of the off signal to be greater than the sixth threshold, and the ratio of the value of the average first parameter of the on signal of the first signal to the value of the average first parameter of the off signal to be greater than the seventh threshold, which is beneficial for the receiving end to correctly receive the first signal sent by the transmitting end and improve communication performance.

[0065] In one embodiment, the signal parameter includes a dynamic range of the value of the first parameter within a frequency domain resource unit, and the signal parameter of the first signal meets the signal parameter indicator, including: the dynamic range of the value of the first parameter within a frequency domain resource unit of the first signal does not exceed an eighth threshold.

[0066] In this embodiment, one frequency domain resource unit may be one or more resource elements (RE) or one or more resource blocks (RB).

[0067] Optionally, the dynamic range of the value of the first parameter in one frequency domain resource unit of the first signal does not exceed an eighth threshold, which includes at least one of the following:

[0068] 1) The on signal or the off signal of the first signal, the difference between the value of the first parameter in a frequency domain resource unit and the average value of the first parameter in a frequency domain resource unit is within a second range, and the second range is related to the eighth threshold.

[0069] For example, the difference between the amplitude, voltage, current or power of the "on" signal or the "off" signal on an RE or RB and the average value of the amplitude, voltage, current or power within an RE or RB is within +X5 or -Y5dB.

[0070] 2) The on signal or the off signal of the first signal, the ratio between the value of the first parameter in a frequency domain resource unit and the average value of the first parameter in a frequency domain resource unit is within a third range, and the third range is related to the eighth threshold.

[0071] For example, the ratio between the amplitude, voltage, current or power of the "on" signal or the "off" signal on one RE or RB and the average value of the amplitude, voltage, current or power within one RE or RB is within X5%.

[0072] The related art does not take into account the dynamic range of the value of the first parameter in a frequency domain resource unit, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the on signal or off signal of the first signal, and the difference between the value of the first parameter in a frequency domain resource unit and the average value of the first parameter in a frequency domain resource unit is within the second range; the on signal or off signal of the first signal, and the ratio between the value of the first parameter in a frequency domain resource unit and the average value of the first parameter in a frequency domain resource unit is within the third range, which is conducive to the receiving end correctly receiving the first signal sent by the transmitting end and improving communication performance.

[0073] In one embodiment, the signal parameter includes EVM or EVM equalizer spectrum flatness, and the signal parameter of the first signal satisfies a signal parameter indicator including at least one of the following:

[0074] 1) The EVM value of the first signal does not exceed a ninth threshold value. For example, the EVM value of the first signal does not exceed 30%.

[0075] 2) The value of the EVM equalizer frequency domain flatness of the first signal does not exceed the tenth threshold, for example, the value of the EVM equalizer frequency domain flatness of the first signal does not exceed 6 dB.

[0076] The related art does not consider EVM or the frequency domain flatness of the EVM equalizer, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the EVM value of the first signal to not exceed the ninth threshold; the value of the frequency domain flatness of the EVM equalizer of the first signal does not exceed the tenth threshold, which is conducive to the receiving end correctly receiving the first signal sent by the transmitting end and improving communication performance.

[0077] In one embodiment, the signal parameter includes a first parameter, and the signal parameter of the first signal satisfies a signal parameter indicator including at least one of the following:

[0078] 1) The value of the first parameter of the on signal of the first signal is higher than the first parameter first target value.

[0079] Optionally, the amplitude, voltage, current or power of the "on" signal is more than X6dB higher than the first target value of the first parameter, where X6 can be a positive or negative number. A positive number means that the amplitude, voltage, current or power of the "on" signal is above the first target value of the first parameter, and a negative number means that the amplitude, voltage, current or power of the "on" signal can be below or above the first target value of the first parameter.

[0080] 2) The value of the first parameter of the off signal of the first signal is lower than the second target value of the first parameter.

[0081] Optionally, the amplitude, voltage, current or power of the "off" signal is more than X7dB lower than the second target value of the first parameter, where X7 can be a positive or negative number. A positive number means that the amplitude, voltage, current or power of the "off" signal is below the second target value of the first parameter, and a negative number means that the amplitude, voltage, current or power of the "on" signal can be above or below the second target value of the first parameter.

[0082] In this embodiment, the first target value of the first parameter and the second target value of the first parameter may be the same or different.

[0083] In this embodiment, the first target value of the first parameter and the second target value of the first parameter may be predefined, network configured, device preconfigured, or determined based on the transmit power (of the first signal). X6 and X7 may also be predefined, network configured, device preconfigured, or determined based on the transmit power.

[0084] In a specific embodiment, the Reader can use OOK-4 modulation to generate a first signal and send the first signal. For the amplitude, voltage, current or power of the "on" signal, it is higher than the first target value of the first parameter, and the amplitude, voltage, current or power of the "off" signal is lower than the second target value of the first parameter, so that the waveforms of the "on" signal and the "off" signal are distinguishable, and the tag can successfully detect the waveforms of the two signals through envelope detection.

[0085] The related art does not take the first parameter of the first signal into consideration, which may easily cause the receiving end to be unable to correctly demodulate and obtain the first signal. This embodiment sets the value of the first parameter of the on signal of the first signal to be higher than the first target value of the first parameter; the value of the first parameter of the off signal of the first signal is lower than the second target value of the first parameter, so that the waveforms of the "on" signal and the "off" signal are distinguishable, which is beneficial for the receiving end to correctly receive the first signal sent by the transmitting end and improve the communication performance.
