[0002] In the related art, fixed-length pulse modulation or non-fixed-length pulse modulation is usually used to realize the modulation of bit information. However, fixed-length pulse modulation has the problem of low spectrum efficiency and requires symbol synchronization. Although non-fixed-length pulse modulation can improve the spectrum efficiency to a certain extent and does not require symbol synchronization, it has the disadvantage of representing the bit information only by the pulse position in the information frame, and when the modulation order is large, the pulse position is greatly different from the starting time slot of the frame, resulting in a longer frame length, so the spectrum efficiency is still not very high.

[0045] See also Figure 2 , Figure 2 1 is a flowchart of an information modulation method provided by an embodiment of the present application, the method is executed by a first device, and the first device may be a terminal or a network side device. Figure 2 As shown, the method comprises the following steps:

[0046] Step 21: The first device modulates the bit information to be modulated using a first pulse characteristic to obtain a modulation symbol; the first pulse characteristic includes any one of the following: a pulse interval between a first pulse and a second pulse in an information frame, a pulse interval between a first pulse and a second pulse in an information frame, and a pulse characteristic of the second pulse;

[0047] Step 22: The first device sends the modulation symbol.

[0048] In the embodiment of the present application, the first pulse and the second pulse have different pulse characteristics. The first pulse can be understood as a fixed reference pulse, and the second pulse can be understood as a variable data pulse.

[0049] Optionally, the information frame may include l (l ≥ 2) time units, that is, an information frame with a length of l (l ≥ 2) time units. The pulse interval between the first pulse and the second pulse can be understood as the number of time units. The specific length of the information frame can be determined according to the number of bits of the bit information to be modulated; for example, if the number of bits of the bit information to be modulated is large, the length of the information frame used for modulation can be increased accordingly.

[0050] Optionally, the number of information frames used for modulation is the same as the number of bit information to be modulated, that is, one information frame is used to modulate one bit information.

[0051] Optionally, the time unit in this embodiment may include but is not limited to at least one of the following: resource element (RE), symbol, time slot, subframe, frame.

[0052] Optionally, when modulating the bit information to be modulated, modulation can be performed using only the pulse interval (or the number of time units) between the first pulse and the second pulse in an information frame, or modulation can be performed jointly using the pulse interval (or the number of time units) between the first pulse and the second pulse in an information frame and the pulse characteristics of the second pulse.

[0053] Through the scheme in the embodiment of the present application, it is possible to modulate the bit information to be modulated by utilizing the pulse interval between two pulses in an information frame, thereby improving the spectrum efficiency of the system, and having good power utilization and bit error rate performance, thereby efficiently realizing the modulation of the bit information.

[0054] Optionally, if the bit information to be modulated has k bits, then: m bits among the k bits are modulated / mapped using the pulse interval between the first pulse and the second pulse in the information frame, and n bits among the k bits are modulated / mapped using the pulse characteristics of the second pulse; wherein, m+n=k, 1≤m≤k, 0≤n<k.

[0055] Optionally, the pulse characteristics of the first pulse and the second pulse may include at least one of the following:

[0056] Pulse width; this pulse width can be understood as the number of time units;

[0057] Pulse amplitude; this pulse amplitude can be understood as the power of the corresponding pulse;

[0058] Pulse phase.

[0059] Optionally, at least one pulse characteristic of the first pulse and the second pulse is different. The first pulse and the second pulse satisfy at least one of the following:

[0060] The pulse width of the first pulse is different from the pulse width of the second pulse;

[0061] The pulse amplitude / power of the first pulse is different from the pulse amplitude / power of the second pulse;

[0062] The pulse phase of the first pulse and the pulse phase of the second pulse are different.

[0063] Optionally, when multiple information frames are used to modulate multiple bits of information to be modulated, the pulse characteristics of the first pulses in the multiple information frames are the same, so as to serve as a reference and reduce the modulation complexity. For example, the pulse characteristics of the first pulses in the multiple information frames, such as pulse width, pulse amplitude, and pulse phase, are the same.

[0064] Optionally, the first pulse may be located at a start time unit position or an end time unit position of the information frame.

[0065] Optionally, the pulse characteristic of the second pulse is related to the n bits to be modulated. When different information frames are used to modulate the multiple bits of information to be modulated, the pulse characteristics of the second pulses in the different information frames may satisfy any of the following:

[0066] In the case where the pulse characteristics of the second pulse are not used to modulate the bit information to be modulated, that is, when n=0, the pulse characteristics of the second pulses in the different information frames are the same; for example, the pulse characteristics of the second pulses in the different information frames, such as the pulse width, pulse amplitude and pulse phase, are the same; in this case, the target modulation method can be determined first, and if the target modulation method includes not using the pulse characteristics of the second pulse to modulate the bit information to be modulated, then when multiple information frames are used to modulate multiple bits of information to be modulated, the pulse characteristics of the second pulses in different information frames are the same, and only the pulse interval between the first pulse and the second pulse is used to modulate the bit information to be modulated; in this way, the modulation process can be simplified, and the demodulation process can be simplified at the same time;

[0067] When the pulse characteristics of the second pulse are used to modulate the bit information to be modulated, that is, when n≥0, the pulse characteristics of the second pulses in different information frames are different; in this case, the target modulation method can be determined first. If the target modulation method includes modulating the bit information to be modulated by the pulse characteristics of the second pulse, then when multiple information frames are used to modulate multiple bits of information to be modulated, the pulse characteristics of the second pulses in different information frames are respectively used to modulate the corresponding parts of the bit information.

[0068] Optionally, when the pulse characteristics of the second pulses in the different information frames are different, at least one pulse characteristic of the second pulses in the different information frames is different, and at least one of the following items may be satisfied:

[0069] The pulse width is different;

[0070] The pulse amplitude is different;

[0071] The pulse phase is different.

[0072] Optionally, when the number of time units in the information frame is not fixed, that is, the number of time units in each information frame used for modulation is not fixed, the first pulse and the second pulse in the information frame may satisfy at least one of the following:

[0073] 1) The first pulse is located at the start time unit position of the information frame, and the number of time units between the second pulse and the end time unit position of the information frame is fixed, for example, a fixed number of c (c ≥ 0) time units;

[0074] 2) The first pulse is located at the end time unit position of the information frame, and the number of time units between the second pulse and the start time unit position of the information frame is fixed, for example, a fixed number of c (c ≥ 0) time units;

[0075] 3) There are a preset number of protection time units between the first pulse and the second pulse, for example, there are x (x≥0) protection time units.

[0076] In this way, through the parameter design of the non-fixed-length information frame, a balance between spectrum efficiency, power efficiency and bit error rate performance can be achieved during pulse modulation.

[0077] Optionally, when the number of time units in the information frame is fixed, that is, the number of time units in each information frame used for modulation is fixed, the first pulse and the second pulse in the information frame satisfy at least one of the following:

[0078] a) The first pulse is located at the starting time unit position of the information frame, and the number of time units between the second pulse and the ending time unit position of the information frame is determined according to at least one of the following: the number of time units l of the information frame, the number of time units i (i≥0) of the first pulse, the number of time units j (j≥0) of the second pulse, the number of protection time units x (x≥0) between the first pulse and the second pulse, the number of time units c (c≥0) between the second pulse and the starting time unit position or the ending time unit position of the information frame, and the pulse interval (number of time units) between the first pulse carrying bit information and the second pulse m -1, m represents the number of bits of the bit information carried by this pulse interval. That is to say, the number of time units between the second pulse and the end time unit position of the information frame is not fixed, and is determined according to parameters such as i, x or c. For example, the number of time units y (y ≥ 0) between the second pulse and the end time unit position of the information frame can be expressed as: y = l-(i+j+x+c+2 m -1).

[0079] b) The first pulse is located at the end time unit position of the information frame, and the number of time units between the second pulse and the start time unit position of the information frame is determined according to at least one of the following: the number of time units l of the information frame, the number of time units i (i≥0) of the first pulse, the number of time units j (j≥0) of the second pulse, the number of protection time units x (x≥0) between the first pulse and the second pulse, the number of time units c (c≥0) between the second pulse and the start time unit position or the end time unit position of the information frame, and the pulse interval (number of time units) between the first pulse carrying bit information and the second pulse m -1, m represents the number of bits of the bit information carried by this pulse interval. That is to say, the number of time units between the second pulse and the starting time unit position of the information frame is not fixed, and is determined according to parameters such as i, x or c. For example, the number of time units y (y ≥ 0) between the second pulse and the starting time unit position of the information frame can be expressed as: y = l-(i+j+x+c+2 m -1).

[0080] In this way, through the parameter design of the fixed-length information frame, a balance among spectrum efficiency, power efficiency and bit error rate performance can be achieved during pulse modulation.

[0163] The present application is described below in conjunction with specific embodiments.

[0164] Embodiment 1

[0165] In the first embodiment, different pulse characteristic dimensions are used to identify the first pulse (or referred to as: reference pulse) and the second pulse (or referred to as: data pulse) for modulating bit information, wherein the first pulse is identified by the pulse amplitude dimension, and the second pulse is characterized by the pulse phase dimension. Without loss of generality, the first pulse may also be identified by pulse width and pulse phase, and the second pulse may also be characterized by pulse amplitude and pulse width dimensions for bit information.

[0166] Modulation process (first device):

[0167] The first device determines the modulation parameters and pulse characteristic dimensions according to the first information obtained (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 1.2 (normalized value) and the phase is 0; the pulse amplitude of the second pulse is 1 (normalized value), the phase representing the bit "0" is 0, and the phase representing the bit "1" is π; a non-fixed-length information frame mode is adopted, and the number of protection time units between the first pulse and the second pulse is x=0 time units; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=0 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=0 time unit. Afterwards, the first device can perform modulation according to the following principles:

[0168] (1) Modulate the first bit by the phase of the second pulse. Figure 4 Option 1 (the first pulse is located at the beginning of the information frame), or Figure 4 Taking scheme 2 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the first bit "0" in the bit "010", and the phase mapped to the second pulse is 0; the second information frame needs to modulate the first bit "1" in the bit "100", and the phase mapped to the second pulse is π; the third information frame needs to modulate the first bit "1" in the bit "111", and the phase mapped to the second pulse is π.

[0169] (2) The last two bits are modulated by the pulse interval (i.e., the number of time units) between the first pulse and the second pulse. Figure 4 Option 1 (the first pulse is located at the beginning of the information frame), or Figure 4 Taking scheme 2 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the last two bits "10" in the bit "010", and the number of time units mapped to the first pulse and the second pulse is 2; the second information frame needs to modulate the last two bits "00" in the bit "100", and the number of time units mapped to the first pulse and the second pulse is 0 (that is, the first pulse and the second pulse are two adjacent pulses), and the third information frame needs to modulate the last two bits "11" in the bit "111", and the number of time units mapped to the first pulse and the second pulse is 3.

[0170] (3) If the mode of first pulse followed by second pulse is adopted (i.e. corresponding to Figure 4In solution 1), the empty time unit after the second pulse can be deleted; at this time, the next time unit of the time unit where the second pulse in the information frame is located is used as the starting time unit of the next information frame, that is, the time unit position where the first pulse of the next information frame is located.

[0171] (4) If the mode of first second pulse and then first pulse is adopted (i.e. corresponding to Figure 4 In scheme 2, the first pulse is located at the end position of the information frame), the empty time unit before the second pulse can be deleted; at this time, the next time unit of the time unit where the first pulse in the information frame is located is used as the starting time unit of the next information frame, that is, the time unit position where the second pulse of the next information frame is located.

[0172] (5) According to the modulation of (1) to (4) above, complete the modulation of other information frames.

[0173] Demodulation process (second device):

[0174] The second device determines the demodulation parameters and pulse characteristic dimensions according to the fourth information obtained (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 1.2 (normalized value) and the phase is 0; the pulse amplitude of the second pulse is 1 (normalized value), the phase representing the bit "0" is 0, and the phase representing the bit "1" is π; a non-fixed-length information frame mode is adopted, and the number of protection time units between the first pulse and the second pulse is x=0 time units; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=0 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=0 time unit. Afterwards, the second device can perform demodulation according to the following principles:

[0175] (1) After system synchronization, determine the starting time unit position of the first information frame and start demodulation.

[0176] (2) According to the fourth information, determine whether the mode is a first pulse followed by a second pulse or a second pulse followed by a first pulse, and determine the number of time units of the information frame according to the corresponding mode, that is, the number of time units between a first pulse and the next first pulse. The first pulse is a pulse with an amplitude of 1.2, and the second device can determine whether the corresponding pulse is the first pulse according to the pulse amplitude / power.

[0177] (3) Demodulate according to the phase of the second pulse. If the phase is 0, it is demodulated to bit "0"; if the phase is π, it is demodulated to bit "1".

[0178] (4) Demodulation is performed according to the number of time units between the first pulse and the second pulse in the information frame. If the number of time units between the first pulse and the second pulse is 0, the demodulation is bit "00"; if the number of time units between the first pulse and the second pulse is 1, the demodulation is bit "01"; if the number of time units between the first pulse and the second pulse is 2, the demodulation is bit "10"; if the number of time units between the first pulse and the second pulse is 3, the demodulation is bit "11".

[0179] (5) According to the demodulation methods (1) to (4) above, complete the demodulation of other information frames.

[0180] This embodiment 1 provides a dual pulse interval modulation in which the first pulse and the second pulse are modulated using the characteristics of different pulse dimensions under a non-fixed-length information frame. The advantage is that compared with the traditional digital pulse interval modulation (Dynamic Packing Injection Molding, DPIM) modulation, since some bits are modulated by the pulse characteristics of the second pulse, it is not necessary to use a lot of space time units / pulse intervals to represent the bit information, thereby making the average length of the information frame smaller, and thus effectively improving the spectrum efficiency of the system. In addition, the first pulse and the second pulse are modulated using the characteristics of different pulse dimensions, so that the detection accuracy of the first pulse is higher, and the insertion of the first pulse can make the first device and the second device perform frame synchronization according to the first pulse, thereby further improving the bit error rate performance of the system.

[0181] Embodiment 2

[0182] Similar to the above-mentioned first embodiment, in the second embodiment, the first pulse and the second pulse are respectively identified based on different pulse characteristic dimensions, wherein the first pulse is identified by the pulse amplitude dimension, and the second pulse is identified by the phase dimension to characterize the bit information. However, different from the above-mentioned first embodiment, an empty time unit is inserted between the first pulse and the second pulse, or an empty time unit is also inserted between the second pulse and the end time unit position / start time unit position of the corresponding information frame, evolving into a double pulse interval modulation with a protection time unit.

[0183] like Figure 5 As shown, the pulse amplitude of the first pulse is 1.2 (normalized value) and the phase is 0; the pulse amplitude of the second pulse is 1 (normalized value), the phase representing the bit "0" is 0, and the phase representing the bit "1" is π; a non-fixed-length information frame mode is adopted, and the number of protection time units between the first pulse and the second pulse is x = 1 time unit; the number of time units between the second pulse and the end time unit position of the corresponding information frame is fixed c = 1 time unit, that is, Figure 5Scheme 1 with a guard time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is fixed c = 1 time unit, that is, Figure 5 Scheme 2 with protection time unit.

[0184] The modulation and demodulation scheme in the second embodiment is the same as that in the first embodiment, except that the modulation and demodulation corresponding to the two protection time units c=1 and x=1 need to be considered in the present embodiment. The specific process includes:

[0185] (1) First device modulation: The last two bits are modulated by the pulse interval (i.e., the number of time units) between the first pulse and the second pulse, and a protection time unit is inserted between the first pulse and the second pulse. Figure 5 Scheme 1 with a guard time unit (the first pulse is located at the beginning of the information frame), or Figure 5 Taking scheme 2 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the last two bits "10" of the bit "010", and the number of time units mapped to the first pulse and the second pulse is 3 (plus 1 protection time unit), and an empty protection time unit is inserted after the second pulse; the second information frame needs to modulate the last two bits "00" of the bit "100", and the number of time units mapped to the first pulse and the second pulse is 1 (plus 1 protection time unit), and an empty protection time unit is inserted after the second pulse; the third information frame needs to modulate the last two bits "11" of the bit "111", and the number of time units mapped to the first pulse and the second pulse is 4 (plus 1 protection time unit), and an empty protection time unit is inserted after the second pulse.

[0186] (2) The second device demodulates: demodulates using the number of time units between the first pulse and the second pulse, and considers that the number of protection time units between the first pulse and the second pulse is 1 (1 protection time unit is added), and inserts an empty protection time unit after the second pulse. If the number of time units between the first pulse and the second pulse is 1, the demodulation is bit "00"; if the number of time units between the first pulse and the second pulse is 2, the demodulation is bit "01"; if the number of time units between the first pulse and the second pulse is 3, the demodulation is bit "10"; if the number of time units between the first pulse and the second pulse is 4, the demodulation is bit "11".

[0187] In the second embodiment, by inserting a protection time unit between the first pulse and the second pulse, or inserting a protection time unit between the second pulse and the start time unit position / end time unit position of the corresponding information frame, the synchronization reliability of the system can be improved, the ability of the system to resist multipath interference can be improved, and the pulse detection false detection rate can be reduced, thereby improving the system bit error rate performance.

[0188] Embodiment 3

[0189] In the third embodiment, the first pulse and the second pulse are respectively identified based on the same pulse characteristic dimension, wherein the first pulse is identified by the pulse amplitude dimension, and the second pulse also uses the pulse amplitude dimension to characterize the bit information. Without loss of generality, the first pulse can also be identified by the pulse width dimension, and the second pulse also uses the pulse width dimension to characterize the bit information; or, the first pulse can also be identified by the pulse phase dimension, and the second pulse also uses the pulse phase dimension to characterize the bit information.

[0190] Modulation process (first device):

[0191] The first device determines the modulation parameters and pulse characteristic dimensions according to the acquired first information (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 2 (normalized value); the pulse amplitude of the second pulse is 1 (normalized value), and the phase representing the bit "0" is 0; the pulse amplitude of the second pulse is 1.5 (normalized value), and the phase representing the bit "1" is π; and the pulse phases of the first pulse and the second pulse representing the bits "1" and "0" are the same; a non-fixed-length information frame mode is adopted, and the number of protection time units between the first pulse and the second pulse is x=0 time units; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=1 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=1 time unit. Afterwards, the first device can perform modulation according to the following principles:

[0192] (1) Modulate the first bit by the amplitude of the second pulse. Figure 6 Option 3 in (the first pulse is located at the beginning of the information frame), or Figure 6 Taking scheme 4 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the first bit "0" in the bit "010", and the amplitude mapped to the second pulse is 1; the second information frame needs to modulate the first bit "1" in the bit "100", and the amplitude mapped to the second pulse is 1.5; the third information frame needs to modulate the first bit "1" in the bit "111", and the amplitude mapped to the second pulse is 1.5.

[0193] (2) The last two bits are modulated by the pulse interval (i.e., the number of time units) between the first pulse and the second pulse. Figure 6 Option 3 in (the first pulse is located at the beginning of the information frame), or Figure 6 Taking scheme 4 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the last two bits "10" in the bit "010", and the number of time units mapped to the first pulse and the second pulse is 2; the second information frame needs to modulate the last two bits "00" in the bit "100", and the number of time units mapped to the first pulse and the second pulse is 0 (that is, it means that the first pulse and the second pulse are two adjacent pulses); the third information frame needs to modulate the last two bits "11" in the bit "111", and the number of time units mapped to the first pulse and the second pulse is 3.

[0194] (3) If the mode of first pulse followed by second pulse is adopted (i.e. corresponding to Figure 6 In solution 3), since the number of time units between the second pulse and the end time unit position of the corresponding information frame is fixed at c = 1 time unit, the time unit after the first protection time unit after the second pulse is deleted; at this time, the second time unit after the time unit where the second pulse in the information frame is located is used as the starting time unit of the next information frame, that is, the time unit position where the first pulse of the next information frame is located.

[0195] (4) If the mode of first second pulse and then first pulse is adopted (i.e. corresponding to Figure 6 In scheme 4, the first pulse is located at the end position of the information frame), since the number of time units between the second pulse and the starting time unit position of the corresponding information frame is fixed c = 1 time unit, the time unit before the first protection time unit before the second pulse is deleted; at this time, the next time unit of the time unit where the first pulse in the information frame is located is used as the starting time unit of the next information frame, that is, the time unit position where the second pulse of the next information frame is located.

[0196] (5) According to the modulation of (1) to (4) above, complete the modulation of other information frames.

[0197] Demodulation process (second device)

[0198] The second device determines the demodulation parameters and pulse characteristic dimensions according to the fourth information obtained (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 2 (normalized value); the pulse amplitude of the second pulse is 1 (normalized value), and the phase representing the bit "0" is 0; the pulse amplitude of the second pulse is 1.5 (normalized value), and the phase representing the bit "1" is π; and the pulse phases of the first pulse and the second pulse representing the bits "1" and "0" are the same; a non-fixed-length information frame mode is adopted, and the number of protection time units between the first pulse and the second pulse is x=0 time units; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=1 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=1 time unit. Afterwards, the second device can perform demodulation according to the following principles:

[0199] (1) After system synchronization, determine the starting time unit position of the first information frame and start demodulation.

[0200] (2) According to the fourth information, determine whether the mode is a first pulse followed by a second pulse or a second pulse followed by a first pulse, and determine the number of time units of the information frame according to the corresponding mode, that is, the number of time units between a first pulse and the next first pulse. The first pulse is a pulse with an amplitude of 2, and the second device can determine whether the corresponding pulse is the first pulse according to the pulse amplitude / power.

[0201] (3) Demodulate according to the amplitude of the second pulse. If the pulse amplitude is 1, it is demodulated to bit "0"; if the pulse amplitude is 1.5, it is demodulated to bit "1".

[0202] (4) Demodulation is performed according to the number of time units between the first pulse and the second pulse in the information frame. If the number of time units between the first pulse and the second pulse is 0, the demodulation is bit "00"; if the number of time units between the first pulse and the second pulse is 1, the demodulation is bit "01"; if the number of time units between the first pulse and the second pulse is 2, the demodulation is bit "10"; if the number of time units between the first pulse and the second pulse is 3, the demodulation is bit "11".

[0203] (5) According to the demodulation methods (1) to (4) above, complete the demodulation of other information frames.

[0204] According to the same principle, it can be extended to the case where the first pulse can also be identified by the pulse width dimension, and the second pulse also uses the pulse width dimension to characterize the bit information; or, the first pulse can also be identified by the pulse phase dimension, and the second pulse also uses the pulse phase dimension to characterize the bit information. In addition, it can also be extended to any x (the number of protection time units between the first pulse and the second pulse is x) and c (the number of time units between the second pulse and the start / end time unit position of the corresponding information frame is a fixed c protection time units). The specific modulation / demodulation process is similar and will not be repeated here.

[0205] This third embodiment provides a double pulse interval modulation in which the first pulse and the second pulse are modulated using the same pulse dimension characteristics under a non-fixed length information frame. The advantage is that the modulation end of the first device only needs to support one modulation dimension characteristic, thereby reducing the implementation complexity.

[0206] Embodiment 4

[0207] Different from the above-mentioned embodiments, the length of the information frame (the number of time units) is not fixed. In the fourth embodiment, the length of each information frame is fixed. Specifically, different schemes can be formed according to whether the first pulse and the second pulse adopt the same pulse characteristic dimension, the front and back patterns of the second pulse and the first pulse in the information frame, whether x protection time units are inserted between the first pulse and the second pulse, whether c protection time units are inserted before the second pulse and the start / end time unit position of the corresponding information frame, etc. Without loss of generality, in the fourth embodiment, different pulse characteristic dimensions are used to respectively identify the first pulse and the second pulse of the modulated bit information, and the number of protection time units between the first pulse and the second pulse is x time units; the number of time units between the second pulse and the start / end time unit position of the corresponding information frame is a fixed c time units; the length of the information frame is set to l time units; and y=l-(i+j+x+c+2 m -1)(y≥0) empty time units are used to keep the length of each information frame fixed at l; i (i≥0) represents the number of time units of the first pulse (pulse width), and j (j≥0) represents the number of time units of the second pulse (pulse width).

[0208] Modulation process (first device):

[0209] The first device determines the modulation parameters and pulse characteristic dimensions according to the first information obtained (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 1.5 (normalized value), the phase is 0, and the pulse width i of the first pulse is 1 time unit; the pulse amplitude of the second pulse is 1 (normalized value), the phase representing the bit "0" is 0, the phase representing the bit "1" is π, and the pulse width j of the second pulse is 1 time unit; a fixed-length information frame mode is adopted, and the length of the information frame is set to l=6; the number of protection time units between the first pulse and the second pulse is x=1 time unit; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=0 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=0 time unit. Afterwards, the first device can perform modulation according to the following principles:

[0210] (1) Modulate the first bit by the phase of the second pulse. Figure 7 Scheme 5 in (the first pulse is located at the beginning of the information frame), or Figure 7 Taking scheme 6 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the first bit "0" in the bit "010", and the phase mapped to the second pulse is 0; the second information frame needs to modulate the first bit "1" in the bit "100", and the phase mapped to the second pulse is π; the third information frame needs to modulate the first bit "1" in the bit "111", and the phase mapped to the second pulse is π.

[0211] (2) The last two bits are modulated by the pulse interval (i.e., the number of time units) between the first pulse and the second pulse, and the number of protection time units between the first pulse and the second pulse is considered to be x=1. Figure 7 Scheme 5 in (the first pulse is located at the beginning of the information frame), or Figure 7 Taking scheme 6 (the first pulse is located at the end position of the information frame) as an example, the first information frame needs to modulate the last two bits "10" in the bit "010", and the number of time units mapped to the first pulse and the second pulse is 3; the second information frame needs to modulate the last two bits "00" in the bit "100", and the number of time units mapped to the first pulse and the second pulse is 1; the third information frame needs to modulate the last two bits "11" in the bit "111", and the number of time units mapped to the first pulse and the second pulse is 4.

[0212] (3) If the mode of first pulse followed by second pulse is adopted (i.e. corresponding to Figure 7In solution 5), since a fixed-length information frame of length l=6 is used, it is necessary to insert an empty time unit after each second pulse in the non-fixed-length information frame to ensure that the length of each information frame is l=6. Figure 7 Taking the first information frame in scheme 5 as an example, the pulse interval between the first pulse and the second pulse is 3 time units, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 1 time unit after the second pulse; in the second information frame, the pulse interval between the first pulse and the second pulse is 1 time unit, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 3 time units after the second pulse; in the third information frame, the pulse interval between the first pulse and the second pulse is 4 time units, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 0 time unit after the second pulse, that is, no time unit is inserted.

[0213] (3) If the mode of first second pulse and then first pulse is adopted (i.e. corresponding to Figure 7 In solution 6), since a fixed-length information frame of length l=6 is used, it is necessary to insert an empty time unit before each second pulse in the non-fixed-length information frame to ensure that the length of each information frame is l=6. Figure 7 Taking the first information frame in Scheme 6 as an example, the pulse interval between the first pulse and the second pulse is 3 time units, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 1 time unit in front of the second pulse; in the second information frame, the pulse interval between the first pulse and the second pulse is 1 time unit, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 3 time units in front of the second pulse; in the third information frame, the pulse interval between the first pulse and the second pulse is 4 time units, the pulse width of the first pulse is 1 time unit, and the pulse width of the second pulse is 1 time unit, so it is necessary to insert 0 time unit in front of the second pulse, that is, no time unit is inserted.

[0214] (5) According to the modulation of (1) to (4) above, complete the modulation of other information frames.

[0215] Demodulation process (second device)

[0216] The second device determines the modulation parameters and pulse characteristic dimensions according to the fourth information obtained (specifically as described in the above embodiment); wherein the pulse amplitude of the first pulse is 1.5 (normalized value), the phase is 0, and the pulse width i of the first pulse is 1 time unit; the pulse amplitude of the second pulse is 1 (normalized value), the phase representing the bit "0" is 0, the phase representing the bit "1" is π, and the pulse width j of the second pulse is 1 time unit; a fixed-length information frame mode is adopted, and the length of the information frame is set to l=6; the number of protection time units between the first pulse and the second pulse is x=1 time unit; the number of time units between the second pulse and the end time unit position of the corresponding information frame is a fixed c=0 time unit, or the number of time units between the second pulse and the start time unit position of the corresponding information frame is a fixed c=0 time unit. Afterwards, the second device can perform modulation according to the following principles:

[0217] (1) After system synchronization, determine the starting time unit position of the first information frame and start demodulation.

[0218] (2) According to the fourth information, determine whether the mode is a first pulse followed by a second pulse or a second pulse followed by a first pulse, and perform demodulation according to every 6 time units as an information frame, that is, the number of time units between a first pulse and the next first pulse. The first pulse is a pulse with an amplitude of 1.5 and a phase of 0, and the second device can determine whether the pulse is the first pulse according to the pulse amplitude / power.

[0219] (3) Demodulate according to the phase of the second pulse. If the phase is 0, it is demodulated to bit "0"; if the phase is π, it is demodulated to bit "1".

[0220] (4) Demodulation is performed according to the number of time units between the first pulse and the second pulse in the information frame, while considering that the number of protection time units between the first pulse and the second pulse is x = 1. If the number of time units between the first pulse and the second pulse is 1, the demodulation is bit "00"; if the number of time units between the first pulse and the second pulse is 2, the demodulation is bit "01"; if the number of time units between the first pulse and the second pulse is 3, the demodulation is bit "10"; if the number of time units between the first pulse and the second pulse is 4, the demodulation is bit "11".

[0221] (5) According to the demodulation methods (1) to (4) above, complete the demodulation of other information frames.

[0222] This embodiment provides a solution under a fixed-length information frame. The greatest advantage is that due to the use of a fixed-length information frame, the information frame in this format has a built-in symbol synchronization capability, thereby reducing the information frame detection error rate, thereby effectively improving the system's bit error rate performance.

[0223] According to the same principle, it can be extended to the case where the first pulse can also be identified by the pulse width dimension, and the second pulse also uses the pulse width dimension to characterize the bit information; or, the first pulse can also be identified by the pulse phase dimension, and the second pulse also uses the pulse phase dimension to characterize the bit information; or, the first pulse and the second pulse are respectively identified by different pulse dimension characteristics. In addition, it can also be extended to the case of arbitrary x (the number of protection time units between the first pulse and the second pulse is x) and c (the number of time units between the second pulse and the start / end time unit position of the corresponding information frame is a fixed c protection time units).

[0224] Embodiment 5

[0225] In the fifth embodiment, the configuration and indication process of the first device and the second device completing data transmission based on differential multi-pulse position and interval modulation under several typical network deployment architectures is given.

[0226] In a typical architecture, the first device or the second device determines the first information and the fourth information, and the device (such as the first device) sends the fourth information to another device (such as the second device), but the device sending the first signal can be either the first device or the second device, wherein the first signal is a signal generated by modulation symbols, that is, a signal after the modulation symbols are subjected to necessary synchronization, pilot insertion and other signal processing, such as Fig. 8A and Figure 8B As shown. This typical architecture includes but is not limited to the base station-UE communication mode, the UE-UE communication mode without network control in the sidelink, the AP STA-STA mode in WiFi, the STA-STA (ie, WiFi direct connection mode), the communication mode in Bluetooth / Zigbee, etc. That is, one device of the communication (here taking the first device as an example) has the ability to determine the modulation and demodulation parameters, and sends the fourth information to the opposite device. It is worth noting that in this architecture, the second device can also determine the first information and the fourth information, and send the first information to the first device. Since the process is similar to the above, it will not be repeated here.

[0227] In another architecture, in addition to the first device and the second device, a third device is also included, and the third device determines and configures the first information / fourth information. Depending on whether the device that configures or indicates the first information / fourth information is the first device, the second device, or the third device, it can be divided into three sub-modes:

[0228] Sub-mode 1: Fig.9A As shown, the third device configures or indicates the first information of the first device, and the subject that configures or indicates the fourth information to the second device is the first device. This scenario is similar to the scenario in which there are a master UE and a slave UE in the sidelink. The base station configures or indicates the first information of the master UE, and the master UE configures or indicates the fourth information of the slave UE.

[0229] Second sub-mode: Fig. 9B As shown, similar to the above-mentioned first sub-mode, the third device configures or indicates the fourth information of the second device, and the subject that configures the first information for the first device is the second device. This scenario is similar to the scenario in which there are a master UE and a slave UE in the sidelink. The base station configures or indicates the first information of the master UE, and the master UE configures or indicates the fourth information of the slave UE.

[0230] The third sub-mode: Fig. 9C As shown, the entity that configures the fourth information for the second device is the third device. This scenario is similar to the scenario in which there are UEs with equal capabilities in the sidelink, and the base station configures the first information or the fourth information for the two UEs at the same time.

[0231] In another architecture, the subject that configures or indicates the first information for the first device and the subject that configures or indicates the fourth information for the second device are not the same device. Fig. 10A As shown, the device that configures or indicates the fourth information for the second device may be the first device in addition to the third device. In one possible solution, the third device may first configure multiple modulation parameter modes in the second device through RRC signaling, and the first device activates one of the parameter modes through MAC-CE, DCI, SCI or L1 signaling. Alternatively, the third device configures or indicates part of the fourth information, and the first device configures or indicates part of the fourth information, and the two together constitute the complete fourth information. Similarly, Fig. 10B As shown, the device that configures or indicates the first information for the first device may be the second device in addition to the third device. In one possible solution, the third device may first configure multiple modulation parameter modes in the first device through RRC signaling, and the second device activates one of the parameter modes through MAC-CE, DCI, SCI or L1 signaling. Alternatively, the third device configures or indicates part of the content in the first information, and the second device configures or indicates part of the content in the first information, and the two together constitute the complete first information.

[0232] It is worth noting that the first signal here is a signal generated by modulation symbols, which is a signal after the modulation symbols have undergone necessary synchronization, pilot insertion and other signal processing.
