For example, it may be a terminal, a base station, or a device with reading and writing functions, such as a reader. The second communication device may be a response device. In one possible implementation, the second communication device may be a tag, that is, a Radio Frequency Identification (RFID) tag, which is the common name of RFID.

For passive tags, they can also be referred to as passive Internet of Things devices (passive IOT).

[0031] In one embodiment, the first communication device may be a network-side device, and the second communication device may be a terminal.

[0032] In a specific embodiment, the first communication device is a reader, and the second communication device is a tag.

[0034] Before S202, the following steps may also be included: The first communication device generates a first signal based on the above modulation method. Optionally, the signal parameters of the first signal corresponding to different modulation methods may be (partially) the same or (partially) different.

[0035] After S202, the following steps may also be included: The second communication device demodulates the received first signal using a demodulation technique corresponding to the above modulation method.

The different characteristics may include, but are not limited to, carrying information, signal waveform, and signal level being different. For example, carrying information bits "0" and "1".

[0037] In the signal transmission method provided by the embodiment of the present application, the first communication device sends a first signal to the second communication device, and the signal parameters of the first signal meet the signal parameter index. By controlling the signal parameters of the first signal to meet the signal parameter index, it is beneficial for the receiving end (such as the second communication device) to correctly receive the first signal sent by the sending end (the first communication device), and improve the communication performance.

[0038] In the following, multiple embodiments will be used to introduce in detail how the signal parameters of the first signal meet the signal parameter index. It can be understood that the embodiments introduced below can be implemented separately or in combination.

[0039] In one embodiment, the signal parameter includes a first parameter jitter, and the signal parameters of the first signal meeting the signal parameter index include: the first parameter jitter of the on signal of the first signal does not exceed the first range.

[0040] The first parameter jitter includes, for example, amplitude jitter, voltage jitter, current jitter, or power jitter.

[0041] The first parameter jitter can also be referred to as the first parameter flatness.

[0042] In this embodiment, the first parameter jitter of the on signal of the first signal not exceeding the first range includes at least one of the following:

[0043] 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 the first range. For example, the above difference is within +X1 or -Y1 dB, and X1 and Y1 can be the same or different.

[0044] 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 (it can also be mV, mA, without limiting the order of magnitude, the same below), the unit of voltage can be V (or mV, etc.), the unit of current can be A (or mA, etc.), and the unit of power can be dB, dBm, W, mW, etc.

[0045] 2) The ratio between the maximum value and the minimum value of the first parameter of the on signal of the first signal is within the first range. For example, the above ratio is within X1%.

[0046] 3) The difference between the value of the first parameter of the on signal of the first signal and the maximum value is within the first range. For example, the above difference is within +X2 or -Y2 dB.

[0047] 4) The ratio between the value of the first parameter of the on signal of the first signal and the maximum value is within the first range. For example, the above ratio is within X2%.

[0048] In a specific embodiment, the Reader can generate the first signal by using OOK-1 modulation and send the first signal. The amplitude jitter, voltage jitter, current jitter, or power jitter on the "1" pulse does not exceed the specified range (the 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 -Y2 dB, and the amplitude, voltage, current, or power on the "0" pulse is 0.

[0049] In the related art, the first parameter jitter of the on signal of the first signal is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. By setting the first parameter jitter of the on signal of the first signal not to exceed the first range in this embodiment, it is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0050] In one embodiment, the signal parameter includes PAPR, cubic metric, or MPR. That the signal parameter of the first signal meets the signal parameter index includes: the value of PAPR, cubic metric, or MPR of the on-signal of the first signal does not exceed a first threshold.

[0051] In the related art, the PAPR, cubic metric, or MPR of the on-signal of the first signal is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. By setting the value of PAPR, cubic metric, or MPR of the on-signal of the first signal not to exceed the first threshold, this embodiment is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0052] The thresholds mentioned in the 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 according to the transmission power (of the first signal).

[0053] In one embodiment, the signal parameter includes the duty cycle. That the signal parameter of the first signal meets the signal parameter index includes at least one of the following:

[0054] 1) The duty cycle of the on-signal of the first signal exceeds a second threshold.

[0055] Optionally, the duty cycle of the on-signal of the first signal is: the ratio of the time when the value of the first parameter of the on-signal is higher than a fourth threshold within a first time to the first time, and the first time can be a sampling period.

[0056] 2) The duty cycle of the off-signal of the first signal exceeds a third threshold.

[0057] Optionally, the duty cycle of the off-signal of the first signal is: the ratio of the time when the value of the first parameter of the off-signal is lower than a fifth threshold within a second time to the second time, and the second time can be a sampling period.

[0058] In the related art, the duty cycle of the first signal is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. By setting 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, this embodiment is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0059] In one embodiment, the signal parameter includes the difference or ratio between the average value of the first parameter of the on-signal and the average value of the first parameter of the off-signal. That the signal parameter of the first signal meets the signal parameter index includes at least one of the following:

[0060] 1) The difference between the average value of the first parameter of the on-signal of the first signal and the average value of the first parameter of the off-signal is greater than the sixth threshold. 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 X3 dB.

[0061] 2) The ratio of the average value of the first parameter of the on-signal of the first signal to the average value of the first parameter of the off-signal is greater than the seventh threshold. 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%.

[0062] In the related art, the difference or ratio between the average value of the first parameter of the on-signal and the average value of the first parameter of the off-signal is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. In this embodiment, by setting the difference between the average value of the first parameter of the on-signal of the first signal and the average value of the first parameter of the off-signal to be greater than the sixth threshold, and the ratio of the average value of the first parameter of the on-signal of the first signal to the average value of the first parameter of the off-signal to be greater than the seventh threshold, it is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0063] In one embodiment, the signal parameter includes the dynamic range of the value of the first parameter within a frequency domain resource unit, and the signal parameter of the first signal satisfying the signal parameter index includes: the dynamic range of the value of the first parameter within a frequency domain resource unit of the first signal does not exceed the eighth threshold.

[0064] In this embodiment, a frequency domain resource unit may be one or more resource elements (REs) or one or more resource blocks (RBs).

[0065] Optionally, the dynamic range of the value of the first parameter within a frequency domain resource unit of the first signal not exceeding the eighth threshold includes at least one of the following:

[0066] 1) For the on-signal or off-signal of the first signal, the difference between the value of the first parameter within a frequency domain resource unit and the average value of the first parameter within a frequency domain resource unit is within the second range, and the second range is related to the eighth threshold.

[0067] For example, the difference between the amplitude, voltage, current or power of the "on" signal or "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 or -Y5 dB.

[0068] 2) The ratio between the value of the first parameter within one frequency-domain resource unit and the average value of the first parameter within one frequency-domain resource unit for the on-signal or off-signal of the first signal is within a third range, and the third range is related to the eighth threshold.

[0069] For example, the ratio between the amplitude, voltage, current, or power of the "on" signal or "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%.

[0070] In the related art, the dynamic range of the value of the first parameter within one frequency-domain resource unit is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. In this embodiment, by setting that the difference between the value of the first parameter within one frequency-domain resource unit and the average value of the first parameter within one frequency-domain resource unit for the on-signal or off-signal of the first signal is within a second range; and the ratio between the value of the first parameter within one frequency-domain resource unit and the average value of the first parameter within one frequency-domain resource unit for the on-signal or off-signal of the first signal is within a third range, it is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0073] 2) The value of the EVM equalizer spectrum flatness of the first signal does not exceed the tenth threshold. For example, the value of the EVM equalizer spectrum flatness of the first signal does not exceed 6 dB.

[0074] In the related art, EVM or EVM equalizer spectrum flatness is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. In this embodiment, by setting that the value of the EVM of the first signal does not exceed the ninth threshold; and the value of the EVM equalizer spectrum flatness of the first signal does not exceed the tenth threshold, it is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improve the communication performance.

[0075] In one embodiment, the signal parameter includes the first parameter, and the signal parameter of the first signal satisfying the signal parameter index includes at least one of the following:

[0076] 1) The value of the first parameter of the on-signal of the first signal is higher than the first target value of the first parameter.

[0077] Optionally, the amplitude, voltage, current, or power of the "on" signal is higher than the first target value X6dB of the first parameter. X6 can be a positive number or a 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 and above the first target value of the first parameter.

[0078] 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.

[0079] Optionally, the amplitude, voltage, current, or power of the "off" signal is lower than the second target value X7dB of the first parameter. X7 can be a positive number or a 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 and below the second target value of the first parameter.

[0080] 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.

The above X6 and X7 may also be predefined, network-configured, device-preconfigured, or determined according to the transmit power.

For the amplitude, voltage, current, or power of the "on" signal to be higher than the first target value of the first parameter and the amplitude, voltage, current, or power of the "off" signal to be lower than the second target value of the first parameter, so that the waveforms of the "on" signal and the "off" signal have distinctiveness, and the Tag can smoothly detect the waveforms of the two signals through envelope detection.

[0083] In the related art, the first parameter of the first signal is not considered, which easily causes the receiving end to be unable to correctly demodulate the first signal. In this embodiment, by setting 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 and the value of the first parameter of the off signal of the first signal to be lower than the second target value of the first parameter, the waveforms of the "on" signal and the "off" signal have distinctiveness, which is beneficial for the receiving end to correctly receive the first signal sent by the sending end and improves the communication performance.
