[0002] This application claims priority to Chinese Patent Application No. 202311362010.5 filed in China on October 19, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to an information modulation method, a demodulation method, an apparatus and a communication device. Background Art

[0004] In related technologies, fixed-length pulse modulation or non-fixed-length pulse modulation is usually used to achieve the modulation of bit information. However, fixed-length pulse modulation has the problem of low spectral efficiency and requires symbol synchronization. Although non-fixed-length pulse modulation can improve spectral efficiency to a certain extent and does not require symbol synchronization, it has the disadvantage of representing bit information only by the pulse position within the information frame. Moreover, when the modulation order is large, the pulse position is significantly different from the starting time slot of the frame, resulting in a longer frame length, and thus the spectral efficiency is still not very high. It can be seen from this that the related technology cannot achieve efficient modulation of bit information.

Taking Figure 4 as an example, in the first information frame, the number of time units between the first pulse and the start time unit position of the corresponding information frame is 0, indicating that the transmitted bit is 00; in the second information frame, the number of time units between the first pulse and the start time unit position of the corresponding information frame is 2, indicating that the transmitted bit is 10; in the third information frame, the number of time units between the first pulse and the start time unit position of the corresponding information frame is 1, indicating that the transmitted bit is 01.

[0149] (2) The other two bits are modulated by the number of time units between the first and second pulses. Again, taking Figure 4 as an example, in the first information frame, the number of time units between the first and second pulses is 4, representing the transmitted bit 11; in the second information frame, the number of time units between the first and second pulses is 3, representing the transmitted bit 10; and in the third information frame, the number of time units between the first and second pulses is 2, representing the transmitted bit 01.

[0150] (3) The empty time unit after the second pulse is deleted, and the time unit after the time unit where the second pulse is located in the corresponding information frame is used as the starting time unit of the next information frame.

[0151] (4) Since each pulse in the information frame does not modulate bit information separately, the input bit 1010 is mapped to the modulation of the second information frame and the corresponding pulse modulation symbol is obtained.

[0152] (5) According to the modulation of (1) to (4) above, the modulation of other information frames is completed.

[0153] Demodulation process (second device):

[0154] The second device determines, based on the acquired fourth information (as described in detail in the above embodiment), demodulation parameters for differential double pulse position and interval modulation when k=4, l=16, m=n=2, and each pulse does not carry additional bit information (i.e., p=0), and performs demodulation according to the following principles:

[0155] (1) After system synchronization, the starting time unit position of the first information frame is determined and demodulation begins.

[0156] (2) For the information frame to be demodulated, first determine the starting time unit of the information frame to be demodulated, and determine the number of time units between the time unit where the first pulse in the information frame is located and the starting time unit, and complete the demodulation of the first part of the bits; at the same time, complete the demodulation of the second part of the bits based on the number of time units between the first pulse and the second pulse. Taking the second information frame in Figure 4 as an example, based on the number of time units between the first pulse and the starting time unit position of the corresponding information frame being 2, the demodulated bit information is 10; at the same time, based on the number of time units between the first pulse and the second pulse being 3, the demodulated bit information is 10.

[0157] (3) Since each pulse in the information frame does not modulate information separately, the demodulation of the second information frame is completed, and the bit information 1010 is obtained.

[0158] (4) According to the demodulation methods (1) to (3) above, complete the demodulation of other information frames.

[0159] Example 2

[0160] Different from the above-mentioned embodiment 1, which completes the modulation of part of the information by the number of time units between the first pulse and the starting time unit position of the corresponding information frame, the present embodiment 2 completes the modulation of part of the information by the number of time units between the second pulse and the ending time unit position of the corresponding information frame. Also taking k=4, l=16, m=n=2 as an example, the modulation and demodulation process in the scheme of the present application is explained. When the number of time units between the first pulse (which can be the above-mentioned first pulse or second pulse) and the second pulse (which can be the above-mentioned second pulse or first pulse) is 1, 2, 3 and 4 respectively, the bits 00, 01, 10 and 11 are represented respectively; when the number of time units between the second pulse and the ending time unit position of the corresponding information frame is 0, 1, 2 and 3, the bits 00, 01, 10 and 11 are represented respectively. The same method can be extended to other cases with arbitrary k, l, m, n values, and the way in which the pulse position or pulse interval represents the bit can also be based on Gray mapping or non-Gray mapping.

[0161] Modulation process (first device):

[0162] The first device determines, based on the acquired first information (as described in the above embodiment), parameters for differential double pulse position and interval modulation when k=4, l=16, m=n=2, and each pulse does not carry additional bit information (i.e., p=0), and performs modulation according to the following principles:

[0163] (1) In each information frame, the time unit of the first pulse is used as the starting time unit, and two bits are modulated by the number of units between the first and second pulses. Taking the third information frame in Figure 5 as an example, the number of time units between the first and second pulses is 2, and the bits representing the transmission are 01 (the first two bits).

[0164] (2) The remaining two bits are modulated by the number of time units between the time unit where the second pulse occurs and the end time unit of the corresponding information frame. Taking the third information frame in Figure 5 as an example, the number of time units between the time unit where the second pulse occurs and the end time unit of the corresponding information frame is 1, so the bits representing the transmission are 01 (the last two bits).

[0165] (3) Optionally, all empty time units before the first pulse in the information frame are deleted, and the time unit before the time unit where the first pulse of the information frame is located is used as the end time unit of the previous information frame, and the time unit where the first pulse of the information frame is located is used as the start time unit of the current information frame.

[0166] (4) Since each pulse in the information frame does not modulate bit information separately, the modulation of the bit 0101 in the third information frame is completed, and the corresponding pulse modulation symbol is obtained.

[0167] (5) According to the modulation of (1) to (4) above, the modulation of other information frames is completed.

[0168] Demodulation process (second device):

[0169] The second device determines, based on the acquired fourth information (as described in detail in the above embodiment), demodulation parameters for differential double pulse position and interval modulation when k=4, l=16, m=n=2, and each pulse does not carry additional bit information (i.e., p=0), and performs demodulation according to the following principles:

[0170] (1) After system synchronization, the starting time unit position of the first information frame is determined. The starting time unit position is the starting position of the first pulse in the corresponding information frame, and demodulation begins.

[0171] (2) For the information frame to be demodulated, first determine the starting time unit of the information frame to be demodulated, and then complete the demodulation of the first part of the bits based on the number of time units between the first pulse and the second pulse in the information frame. At the same time, complete the demodulation of the second part of the bits based on the number of time units between the time unit where the second pulse is located and the end time unit of the information frame. Taking the third information frame in Figure 2 as an example, based on the number of time units between the first pulse and the second pulse being 2, the demodulated bit information is 01; at the same time, based on the number of time units between the time unit where the second pulse is located and the end time unit of the information frame being 1, the demodulated bit information is 01.

[0172] (3) Since each pulse in the information frame does not modulate information separately, the demodulation of the third information frame is completed and the bit information 0101 is obtained.

[0173] (4) According to the demodulation methods (1) to (3) above, complete the demodulation of other information frames.

[0174] Example 3

[0175] In the solution of the present application, the two pulses in each information frame can also carry additional bit information through pulse amplitude, phase, etc., as shown in the following examples.

[0176] In one possible example, the pulse amplitude or intensity of each pulse also carries p bits of information. As shown in Figure 6A, the pulses within each information frame support four types of amplitude modulation, so each pulse can carry 2 bits of information in the amplitude dimension. If an information frame can carry 8 bits of information, then 4 bits can be modulated by the position and interval between two pulses, and 4 bits can be modulated by the amplitude of the two pulses.

[0177] In one possible example, the phase of each pulse also carries p bits of information. As shown in Figure 6B, the pulses within each information frame support two types of phase modulation, so each pulse can carry one bit of information in the phase dimension. If an information frame can carry six bits of information, then four bits can be modulated by the position and interval between two pulses, and two bits can be modulated by the phase of the two pulses.

[0178] In a possible example, the amplitude difference between two pulses can also carry p bits of information. As shown in Figure 7A, each pulse supports 4-order differential amplitude modulation 4DASK, with amplitudes of 1, α, α 2 ,α 3. This 4DASK is modulated according to the method shown in Table 1 below, thereby obtaining the pulse symbol shown in FIG7A. It is worth mentioning that in FIG7A, the amplitude of the pulse before the first pulse in the first information frame (i.e., the second pulse in the previous information frame) is 1, and the pulse amplitude of the first pulse is 1, which means that the first pulse in the first information frame can modulate bit 00; next, since the amplitude of the first pulse in the first information frame is 1, the amplitude of the second pulse in the first information frame is α 3 , the transformation coefficient of the two is γ k =α 3 , indicating that the second pulse in the first information frame can modulate bit 10; next, since the amplitude of the second pulse in the first information frame is α 3 , the amplitude of the first pulse in the second information frame is α, and the transformation coefficient of the two is γ k =1 / α 2 , indicating that the second pulse in the second information frame can modulate bit 11; next, since the amplitude of the first pulse in the second information frame is α, the amplitude of the second pulse is α 2 , the conversion coefficient of the two is α, so the second pulse in the second information frame can modulate the bit 01. According to the same modulation method, the bits that can be modulated by each pulse in other information frames can be obtained.

[0179] Table 1

[0180] In one possible example, the phase difference between the two pulses can also carry p bits of information. As shown in FIG7B , each pulse supports 8th-order differential phase modulation 8DPSK. This 8DPSK can be modulated in the manner shown in Table 2 below, thereby obtaining the pulse symbol shown in FIG7B . It is worth mentioning that in FIG7B , the phase of the pulse before the first pulse in the first information frame (i.e., the second pulse in the previous information frame) is 0, and the phase of the first pulse is π / 4, and the phase difference between the two is π / 4, which means that the first pulse in the first information frame can modulate bit 001; next, the phase of the second pulse in the first information frame is 5π / 4, and the phase difference with the previous pulse is π, which means that the second pulse in the first information frame can modulate bit 110; the phase of the first pulse in the second information frame is 2π / 4, and the phase difference between it and the previous pulse (i.e., the second pulse in the first information frame) is This means that the second pulse modulated bit in the second information frame is 111. According to the same modulation method, each pulse modulated bit in other information frames can be obtained.

[0181] Table 2

[0182] Example 4

[0183] In this fourth embodiment, a configuration and instruction process of completing data transmission by a first device and a second device based on differential multi-pulse position and interval modulation under several typical network deployment architectures is provided.

[0184] In a typical architecture, the first information and the fourth information are determined by the first device or the second device, and the fourth information is sent by the device (such as the first device) 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 the modulation symbol, that is, the modulation symbol is subjected to necessary synchronization, pilot insertion and other signal processing, as shown in Figures 8A and 8B. This typical architecture includes but is not limited to a base station-UE communication mode, a UE-UE communication mode without network control in sidelink, an AP station (Station, STA)-STA mode in WiFi, a STA-STA (i.e., WiFi direct connection mode), a communication mode in Bluetooth / Zigbee, etc. That is, one of the communicating devices (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.

[0185] 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:

[0186] Submode 1: As shown in Figure 9A, the third device configures or indicates the first information to the first device, and the first device is the subject that configures or indicates the fourth information to 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 to the master UE, and the master UE configures or indicates the fourth information to the slave UE.

[0187] Second sub-mode: As shown in Figure 9B, similar to the first sub-mode mentioned above, 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 master UE and slave UE in 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.

[0188] Sub-mode 3: As shown in FIG9C , 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 sidelink. The base station configures the first information or the fourth information for the two UEs at the same time.

[0189] In another architecture, the entity that configures or indicates the first information for the first device and the entity that configures or indicates the fourth information for the second device are not the same device. As shown in Figure 10A, the device that configures or indicates the fourth information for the second device can be the first device in addition to the third device. In one possible solution, the third device can 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, as shown in Figure 10B, the device that configures or indicates the first information for the first device can be the second device in addition to the third device. In one possible solution, the third device can 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 first information, and the second device configures or indicates part of the first information, and the two together constitute the complete first information.

[0190] It is worth noting that the first signal here is a signal generated by modulation symbols, which is a signal obtained by performing necessary signal processing such as synchronization and pilot signal insertion on the modulation symbols.
