Technical Field

The present application relates to the field of communication technology, and in particular to a communication modulation method, device and storage medium.

Background Art

In some communication systems, such as the fifth-generation (5G) system, in order to ensure communication effects and overcome problems in long-distance signal transmission, the signal spectrum is often moved to a high-frequency channel for transmission, such as converting various baseband signals into modulated signals suitable for channel transmission. This process of loading the signal to be sent into a high-frequency channel is called signal modulation. In the modulation technology of communication, when transmitting information, an activation resource can be determined from at least two pre-set candidate resources within a unit time (such as a symbol or a transmission cycle), and the information to be transmitted is represented by the activation resource.

However, in a unit time, an active resource is always determined to represent the information to be transmitted, which limits the transmission rate. If the transmission rate is increased by increasing the number of candidate resources, the total number of candidate resources will increase exponentially with the number of bits of the transmitted information, thus reducing the spectrum efficiency.

Therefore, how to perform signal modulation to increase the transmission rate without reducing the spectrum efficiency is a problem that needs to be solved urgently.

To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail in conjunction with FIG. 1. FIG. 1 shows a schematic diagram of a communication system applicable to the communication method of the embodiments of the present application. As shown in FIG. 1, a communication system 100 may include a network device and a terminal device. The number of network devices and terminal devices may be one or more, such as the network device 110 and terminal devices 121 to 123 shown in FIG. 1. In the communication system 100, the network device 110 may communicate with at least one of the terminal devices 121 to 123 through a wireless air interface.

Information, the terminal device 121 can send uplink information to the network device 110, and the terminal devices 121 and 122 can communicate through a sidelink to exchange sidelink information.

The communication modulation method provided in the present application can be applied to the modulation of uplink information, the modulation of downlink information or the modulation of side information. The uplink information, the downlink information and the side information can all include signaling and/or data. The candidate resources in the embodiments of the present application may include but are not limited to: at least one of: frequency resources, time resources, time-frequency two-dimensional resources (hereinafter referred to as time-frequency resources), and code channel resources. It should be noted that the candidate resources are resources agreed upon between the receiving end and the transmitting end for information transmission.

In the embodiment of the present application, activating a candidate resource in the signal modulation process means using this resource to send information, and the activated candidate resource or the resource to be activated can be called an activated resource. Activating a candidate resource from at least two candidate resources can be expressed as determining an activated resource from at least two candidate resources and sending information through the activated resource, or can be expressed as selecting an activated resource from at least two candidate resources and sending information through the activated resource. When different expressions are used for the convenience of expression below, their meanings are consistent.

In the embodiments of the present application, candidate resources and activation resources are defined to facilitate the distinction between whether they are used for information transmission. In fact, both candidate resources and activation resources are resources that can be used for information transmission as agreed between the sender and the receiver. The present application does not limit the naming of candidate resources and activation resources. For example, a candidate resource can be called a first resource, an activation resource can be called a second resource, and the first and second are only used to distinguish different resources, and are not used to limit the scope of the embodiments of the present application.

To facilitate understanding, the modulation technology related to the embodiments of the present application is first described.

1. Frequency shift keying (FSK) modulation. In FSK modulation, multiple frequency resources are agreed upon between the receiving end and the transmitting end. During the information transmission process, the transmitting end transmits information by activating one of the multiple frequency resources.

Referring to FIG. 2a, for example, the number of frequency resources agreed upon by the receiving end and the transmitting end is 4, including channels 1 to 4. The transmitting end activates channel 1 in an orthogonal frequency division multiplexing (OFDM) symbol to transmit to represent the first information state, such as 2 bits "00"; activates channel 2 in an OFDM symbol to transmit to represent the second information state, such as 2 bits "01"; activates channel 3 in an OFDM symbol to transmit to represent the third information state, such as 2 bits "10"; activates channel 4 in an OFDM symbol to transmit to represent the fourth information state, such as 2 bits "11".

2. Pulse position modulation (PPM) modulation. In PPM modulation, multiple time resources (such as multiple time slots) are agreed upon between the receiving end and the transmitting end. During the information transmission process, the transmitting end transmits information by activating one of the multiple time resources.

Referring to FIG. 2b , for example, in information transmission based on PPM modulation, time is divided into time slots, and each S slots (such as 4 slots) is a cycle, or a transmission cycle. Exemplarily, the information state represented by the transmission of time slot 3 in cycle 1 activated by the transmitter is 2 bits "10"; the information state represented by the transmission of time slot 1 in cycle 2 is 2 bits "00"; the information state represented by the transmission of time slot 4 in cycle 3 is 2 bits "11", and so on.

3. Joint time/frequency modulation. In joint time/frequency modulation, multiple time/frequency resources are agreed upon between the receiver and the transmitter. During information transmission, the transmitter transmits information by activating one of the multiple time/frequency resources.

Referring to FIG. 2c, for example, in information transmission based on time-frequency joint modulation, time is divided into time slots, and each S slots (such as 2 slots) is a period, or a carrier transmission period. In a period, there are multiple candidate frequencies (such as two candidate frequencies in each period), and each candidate frequency in each slot constitutes a time-frequency resource. For example, the information state represented by the time-frequency resource {candidate frequency 1, slot 2} activated by the transmitter in period 1 for transmission is 2 bits "01"; the information state represented by the time-frequency resource {candidate frequency 2, slot 1} activated in period 2 for transmission is 2 bits "10"; the information state represented by the time-frequency resource {candidate frequency 1, slot 2} activated in period 3 for transmission is 2 bits "01".

In the above modulation technology, the transmitter always activates one resource to express the information to be transmitted within a unit time (such as a time unit or a period). When the transmission efficiency needs to be improved, the number of resources agreed between the transmitter and the receiver will increase exponentially with the number of bits of the transmitted information, resulting in low spectrum efficiency. Taking FSK modulation as an example, if the number of bits of the information to be transmitted is 2, the number of frequency resources agreed between the receiver and the transmitter is 2 to the square, that is, 4 frequency resources. If the number of bits of the information to be transmitted is 3, the number of frequency resources that need to be agreed between the receiver and the transmitter is 2 to the cube, that is, 8 frequency resources. Similarly, if the number of bits of the information to be transmitted is 4, the number of frequency resources agreed between the receiver and the transmitter is 2 to the 4th power. power, that is, 16 parallel frequency resources; if the number of bits of information to be transmitted is 5, the number of frequency resources agreed between the receiving end and the transmitting end is 2 to the power of 5, that is, 32 parallel frequency resources. In this case, if the transmission rate increases by 1 bit per time unit, the number of parallel frequency resources used needs to be doubled, resulting in a decrease in the spectrum efficiency of the communication system.

It should be noted that the above-mentioned time unit may be a time slot, a sub-frame, a symbol, or other time units defined in the future. It should be noted that the time unit is a unit of measurement in the time domain and is not necessarily the smallest time unit. The method provided in the embodiment of the present application will be described below using a symbol as an example of a time unit. It is understandable that the description of the symbol in the following embodiment may also be replaced by other time units, such as a sub-frame, a symbol, etc. The embodiment of the present application does not limit this. The above-mentioned period may include one or more time units.

In response to the above technical problems, an embodiment of the present application provides a modulation scheme to determine one or more activation resources from at least two candidate resources in the same time unit, and the number of at least two candidate resources is less than 2 to the power of N, where N is the number of bits included in the information sent by the activation resource. This scheme can improve the transmission rate.

The communication method provided in the embodiments of the present application will be described below with reference to the accompanying drawings.

When the method provided by the embodiment of the present application is applied to downlink transmission, the first device may be a network device (such as the network device 110 in Figure 1), and the second device may be a terminal device (such as at least one of the terminal devices 121 to 123 in Figure 1). When the method provided by the embodiment of the present application is applied to uplink transmission, the first device may be a terminal device (such as any one of the terminal devices 121 to 123 in Figure 1), and the second device may be a network device (such as the network device 110 in Figure 1). When the method provided by the embodiment of the present application is applied to side transmission, the first device may be, for example, the terminal device 121 in Figure 1, and the second device may be, for example, the terminal device 122 in Figure 1.

Fig. 3 is a schematic interactive flow chart of a communication modulation method 200 provided in an embodiment of the present application. As shown in Fig. 3, the method 200 may include part or all of the processes from S210 to S230. Each step in the method 200 is described below.

S210, the first device determines m activation resources from M candidate resources, where m is an integer greater than or equal to 1 and less than or equal to M, and the m activation resources are used to represent the first information;

S220: The first device sends first information to the second device through the M candidate resources. Correspondingly, the second device receives the first information sent by the first device through the M candidate resources.

S230: The second device demodulates the first information.

Among them, the M candidate resources may be candidate resources agreed upon between the first device and the second device, and the M candidate resources belong to the same time unit or the same period. The time unit and period have been described in the previous text and will not be repeated for the sake of brevity.

The first information is the signaling and/or data that the first device needs to send to the second device. The first information may include N bits, where N is a positive integer. In this case, the first device and the second device may agree that M candidate resources are used for the transmission of N bits of information, where M is an integer greater than or equal to 2. Further, in order to increase the transmission rate, the number of candidate resources M agreed between the first device and the second device should also be less than 2 to the power of N.

When the number M of candidate resources is less than 2 to the power of N, information is always transmitted through one activation resource, and the transmission of N bits of information cannot be supported. See the examples shown in Figures 2a to 2c, which will not be repeated for the sake of brevity. Therefore, in an embodiment of the present application, the first device can determine one or more activation resources from the M candidate resources, and characterize the first information through one or more activation resources. It should be understood that when the first device can determine at least two activation resources from the M candidate resources, each different activation resource can express a different information state, every two different activation resource combinations can express different information states, and every three different activation resource combinations can express different information states. Therefore, the transmission capacity of the information transmitted by the M candidate resources is enhanced, and the transmission rate is increased without increasing the candidate resources.

For example, assuming that the number of bits of the first information is 2, the number of candidate frequency resources in the same symbol may be 3 (including frequency resources 1 to 3). See Table 1 below, y is a vector indicating N bits of information, x indicates an activated resource among the M candidate resources (x may be an activation vector hereinafter), each element in x corresponds to a candidate resource, and a value of 1 corresponds to a candidate resource. The candidate resource corresponding to the element is activated, or the candidate resource corresponding to the element with a value of 1 is determined as the activated resource. When the first information is [0 0], the first device can determine frequency resource 3 as the activated resource among frequency resources 1 to frequency resources 3, or the first device activates frequency resource 3; when the first information is [0 1], the first device can activate frequency resource 1 among frequency resources 1 to frequency resources 3; when the first information is [1 0], the first device can activate frequency resources 1 and 2 among frequency resources 1 to frequency resources 3; when the first information is [1 1], the first device can activate frequency resources 1, 2, and 3 among frequency resources 1 to frequency resources 3.

Table 1

It should be understood that Table 1 is only an example and not a limiting description. For example, when the first information is [0 1], the first device can activate frequency resource 2 among frequency resources 1 to frequency resources 3, etc., as long as the activation resources corresponding to different information states of the first information are different.

In another example, assuming that the number of bits of the first information is 3, the number of candidate frequency resources in the same symbol may be 4 (including frequency resource 1 to frequency resource 4). See Table 2 below. When the first information is [0 0 0], the first device may activate frequency resource 4 from frequency resource 1 to frequency resource 4. The corresponding relationship between other information states and activated resources in Table 2 is similar, and will not be repeated for brevity.

Table 2

The steps in method 200 are described below through three possible embodiments.

Embodiment 1:

The first device may determine an activation vector of the first information based on a first matrix, where the first matrix includes elements of N rows and M columns, and the activation vector is used to indicate m activation resources representing the first information.

The activation vector can be understood as the indication information of activating resources, and the activation vector is only one kind of indication information. The activation vector may include M elements, each of which corresponds to a candidate resource. When the element is a first value, it indicates that the candidate resource corresponding to the element is activated, or in other words, when the element is a first value, it indicates that the corresponding candidate resource is an activated resource. Among them, the first value can be "1", of course, this application is not limited to this, for example, the first value can be "0".

The above-mentioned first matrix can also be called a generation matrix. Through the first matrix, the vector of first information can be converted into a vector (such as an activation vector) indicating an activated resource among M candidate resources.

Exemplarily, the first matrix G may include a first submatrix I, and the first submatrix I may be an identity matrix. For example, if the number of bits of the first information is 3, the first submatrix I may be However, this application does not limit this, and the first submatrix I can also be any square matrix with elements on the diagonal being 1 and elements on the off-diagonal being 0, such as

Exemplarily, the first matrix may further include a second submatrix u, the elements of which are all 1. The sum of the number of columns of the second submatrix u and the number of columns of the first submatrix G is equal to M. For example, the first device and the second device agree on 4 candidate resource transmissions. 3 bits of first information, then the second sub-matrix First Matrix

For example, the vector y indicating the first information = [1 0 1], the activation vector can be obtained by calculation That is, it is determined that the m activated resources include frequency resources 1 and 3.

In some implementations of the above-mentioned embodiment 1, in order to increase the transmission difference between N bits of different information and improve the stability of information transmission, after converting the first information according to the first matrix, the first device determines the activation vector according to the second vector and the converted vector (such as the first vector), wherein the second vector is used to indicate the offset between the M elements in the activation vector and the M elements in the first vector.

Optionally, the last element in the second vector is 1, and all elements except the last element are 0.

Still taking the example of the first device and the second device agreeing to use 4 candidate resources to transmit 3 bits of first information, the vector indicating the first information y = [1 0 1], the activation vector can be obtained by calculation That is, it is determined that the m activated resources include frequency resources 1, 3 and 4. The relationship between the vector y and the activation vector x in different information states can be seen in Table 2 above.

The first device sends the first information to the second device through the M candidate resources. The second device can receive the first information sent by the first device through the M candidate resources, where the M candidate resources include the m activation resources, and then demodulate the first information.

In the above-mentioned first embodiment, the second device can demodulate the first information according to the first mapping relationship and the m activation resources, where the first mapping relationship is a mapping relationship between N bits of information and activation resources in the M candidate resources. It should be understood that the activation vector indicating the m activation resources corresponds to N bits of information in the first mapping relationship, which is the demodulated first information.

The first mapping relationship may be preset or configured, for example, the first mapping relationship may be preset in the first device and the second device, or the first mapping relationship may be configured from the first device to the second device, or the first mapping relationship may be configured from the second device to the first device; or the first mapping relationship may be agreed upon by a protocol.

Alternatively, the second device may generate the first mapping relationship based on the first matrix. The second device may generate the first mapping relationship based on the first matrix, which may include that the second device generates an activation vector corresponding to each information state of the N-bit information in the first mapping relationship based on the first matrix. Taking the example of the first device and the second device agreeing to transmit 3 bits of information on 4 candidate resources, the first mapping relationship can be found in Table 2 above. The second device generates an activation vector corresponding to an information state in the first mapping relationship based on the first matrix, which is the same or similar to the activation vector generated by the first device based on the first matrix for the first information, and will not be repeated for the sake of brevity. Of course, the second device can also determine the activation vector corresponding to each information state based on the first matrix and the second vector. The specific implementation method can refer to the first device determining the activation vector of the first information based on the first matrix and the second vector, which has the same or corresponding implementation method, and will not be repeated for the sake of brevity.

In addition to the demodulation process of the above example, the second device can also directly demodulate the first information based on the first matrix (or based on the first matrix and the second vector) and the m activation resources. The demodulation process can be the inverse process of the first device determining the m activation resources of the first information based on the first matrix (or based on the first matrix and the second vector).

Referring to FIG. 4 , in some embodiments, the method 200 further includes: S240, the first device sends indication information (such as the first indication information and/or the second indication information hereinafter) to the second device; correspondingly, the second device receives the indication information sent by the first device, so that the second device demodulates the first information according to the indication information. It should be noted that the embodiment of the present application does not limit the execution order between S240 and S210.

In the above S240, the first device may send first indication information to the second device, where the first indication information may be used to indicate at least one of the following:

First matrix;

The second vector;

The number of candidate resources M;

The number of bits N of the first information.

The second device may demodulate the first information based on the content of the first indication information. Optionally, the information not indicated in the first indication information may be preset information, preconfigured information, or information agreed upon by a protocol. For example, the second vector may be agreed upon by a protocol, in which case, the second vector does not need to be indicated by the first indication information.

In the above-mentioned embodiment 1, the first device and the second device can both modulate or demodulate the first information based on the first matrix (in some embodiments, based on the first matrix and the second vector). Therefore, there is no need to synchronize the mapping relationship between the information status and the activation resources between the first device and the second device, so as to avoid the synchronization mapping relationship causing a large communication overhead when the number of information bits transmitted is large.

Embodiment 2:

The first device may determine m activation resources according to the mapping relationship between the N bits of information and the activation resources in the M candidate resources, such as the mapping relationship embodied in the above Table 1 and Table 2. The mapping relationship may be preset or configured, for example, the mapping relationship may be preset in the first device and the second device, or the mapping relationship may be configured by the first device to the second device, or the mapping relationship may be configured by the second device to the first device; or the mapping relationship may be agreed upon by a protocol.

Optionally, the mapping relationship may be generated by the first device. Exemplarily, the first device may determine activation vectors corresponding to different information states of N bits according to the first matrix. It should be understood that when the first device generates a mapping relationship based on the first matrix, if the mapping relationship is not preset in the second device, the first device may indicate the first matrix to the second device without indicating the mapping relationship to the second device, which may reduce the overhead of data transmission.

The first matrix has been described in the above example and will not be described again here. The first device generates an activation vector corresponding to each information state in the mapping relationship based on the first matrix, which is the same or similar to the process in which the first device generates an activation vector for the first information based on the first matrix in the above first example and will not be described again here.

In some implementations of the above-mentioned embodiment 2, in order to increase the transmission difference between N bits of different information and improve the stability of transmission. The first device can generate an activation vector corresponding to each information state in the mapping relationship based on the first matrix and the second vector. Among them, the second vector has been described in the above-mentioned first example, and the activation vector corresponding to each information state is determined based on the first matrix and the second vector, which is similar to the first device determining the activation vector of the first information, and will not be repeated for the sake of brevity. Still taking the example of the first device and the second device agreeing to transmit 3 bits of information using 4 candidate resources, the mapping relationship can be seen in Table 2 above.

Similar to the first embodiment, the second device can receive the first information sent by the first device through M candidate resources, where the M candidate resources include m activation resources, and then demodulate the first information. The manner in which the second device demodulates the first information is referred to in the first embodiment above, which will not be described again for brevity.

In the above-mentioned embodiment 2, the first device may also send the first indication information to the second device; accordingly, the second device receives the first indication information sent by the first device, so that the second device demodulates the first information according to the first indication information. See S240 in FIG. 4. It should be noted that the embodiment of the present application does not limit the execution order between S240 and S210. The first indication information is described in the above-mentioned embodiment 1, and will not be repeated for the sake of brevity.

In the above-mentioned second embodiment, the first device determines m activation resources based on the mapping relationship between N bits of information and activation resources in M candidate resources, avoiding determining the activation vector of the information to be transmitted based on the first matrix (in some embodiments, based on the first matrix and the second vector) every time information is transmitted, but directly searching for the activation resources of the information to be transmitted from the mapping relationship, thereby improving processing efficiency and further improving data transmission efficiency.

Embodiment three:

M candidate resources can be divided into K resource groups, each of which includes at least one candidate resource. For example, the i-th resource group includes N _i candidate resources. Wherein, K is an integer greater than 1, and K is less than M. The first device can determine at least one activation resource from each resource group in the at least one resource group to obtain m activation resources. The at least one resource group is part or all of the K resource groups. The at least one activation resource determined by each resource group in the at least one resource group is used to represent the second information, and the second information represented by the at least one resource group respectively constitutes the first information, that is, the first information includes at least one second information.

It should be noted that the numbers of candidate resources respectively included in the K resource groups may be the same, different, or partially the same.

As an example, the number of candidate resources in most of the K resource groups is as consistent as possible. For example, if the remainder of M divided by L is equal to 0, the K resource groups all include L candidate resources, that is, the M candidate resources are evenly divided into each resource group, so that each resource group includes K candidate resources; if the remainder of M divided by L is equal to k, and k is not equal to 0, K-1 resource groups among the K resource groups all include L candidate resources, and the remaining resource groups among the K resource groups include k candidate resources. Dividing the candidate resources into K resource groups as evenly as possible can achieve better demodulation effect.

Optionally, when L is equal to 4, the second device has a better demodulation effect when demodulating the first information.

In an implementation of the third embodiment, the first device may determine a candidate resource from at least one resource group. For example, the first device may determine one of the frequency resources based on the FSK modulation technology for each resource group in the at least one resource group; or determine one of the time resources based on the PPM modulation technology; or determine one of the time-frequency two-dimensional resources based on the time-frequency joint modulation technology. The following is an exemplary description using FSK modulation as an example in conjunction with FIG. 5a and FIG. 5b.

Referring to FIG. 5a, 16 candidate resources (such as frequency resources 1 to 16) are divided into four resource groups (such as resource groups 1 to 4), and each resource group includes 4 candidate resources, such as resource group 1 includes frequency resources 1 to 4, resource group 2 includes frequency resources 5 to 8, resource group 3 includes frequency resources 9 to 12, and resource group 4 includes frequency resources 13 to 16. If one frequency resource is determined from each resource group, and the frequency resources activated in each of the four resource groups can transmit 2 bits of second information, then the frequency resources activated in the four resource groups can transmit 8 bits of first information. For example, if frequency resource 3 is determined in resource group 1, the information state of the second information transmitted by the activated frequency resource 3 in resource group 1 is 10; if frequency resource 5 is determined in resource group 2, the information state of the second information transmitted by the activated frequency resource 5 in resource group 2 is 00; if frequency resource 12 is determined in resource group 3, the information state of the second information transmitted by resource group 3 is 11; if frequency resource 14 is determined in resource group 4, the information state of the second information transmitted by resource group 4 is 01. The information state of the four second information transmitted by the four resource groups constituting the first information is [10001101].

Referring to FIG. 5b , 16 candidate resources (such as frequency resources 1 to 16) are divided into three resource groups (such as resource groups 1 to 3), resource group 1 includes frequency resources 1 to 8, resource group 2 includes frequency resources 9 to 12, and resource group 3 includes frequency resources 13 to 16. If one frequency resource is determined from each resource group, resource group 1 can transmit 3-bit second information, resource groups 2 and 3 can both transmit 2-bit second information, and the activated frequency resources in the three resource groups can transmit 7-bit first information. If frequency resource 5 is determined in resource group 1, the information state of the second information transmitted by the activated frequency resource 5 in resource group 1 is 100; if frequency resource 10 is determined in resource group 2, the information state of the second information transmitted by the activated frequency resource 10 in resource group 2 is 01; if frequency resource 15 is determined in resource group 3, the information state of the second information transmitted by resource group 3 is 10. The information state of the first information composed of the 3 second information transmitted by the three resource groups is [1000110].

It can be seen that when 16 parallel candidate resources are agreed upon between the first device and the second device, no matter which resource grouping method is adopted, the number of bits of the first information that can be transmitted by the first device within a unit time is greater than the number of bits that can be transmitted when an activated resource is always determined from the 16 candidate resources (log ₂ 16=4), thereby achieving an increase in the transmission rate.

Exemplarily, the first device may determine an activation resource from at least one candidate resource in the resource group according to the second mapping relationship for each resource group in the K resource groups. In the second mapping relationship, one information (or information state) corresponds to one activation resource. The first device may determine an activation resource corresponding to the second information to be transmitted based on the second information to be transmitted, and transmit the second information through the one activation resource.

Correspondingly, the second device receives the second information transmitted by the first device through the one activation resource, and can determine the second information in the second mapping relationship based on the one activation resource, that is, the second device demodulates the second information according to the second mapping relationship and an activation resource in the corresponding resource group.

In order to further improve the transmission rate, in an implementation of the above-mentioned embodiment 3, the first device can determine one or more activation resources from at least one resource group, so that the number of bits N′ of the second information that can be transmitted by the resource group is greater than log ₂ M′, where M′ is the number of candidate resources in the resource group, and N′ and M′ are both positive integers. The first device determines one or more activation resources from a resource group, which is similar to the first device determining m activation resources from M candidate resources in the above-mentioned embodiments 1 and 2, with the difference that the first device determines the activation resources from the resource group in embodiment 3, while embodiments 1 and 2 determine the activation resources from M candidate resources.

Exemplarily, the first device may determine the activated resources in the resource group based on the following two methods:

Method 1: The first device determines the activation resources of the second information according to the second mapping relationship. The second mapping relationship is a mapping relationship between N′ bits of information and activation resources in M′ candidate resources. The first device can search for activation resources that match the information state of the second information in the mapping relationship according to the N′ bits of second information to be transmitted. The second mapping relationship is similar to the first mapping relationship in the aforementioned example, and the difference between the two is that the M′ candidate resources in the second mapping relationship are part of the M candidate resources in the first mapping relationship.

In the first manner above, demodulating the first information by the second device may include: demodulating the second information according to the second mapping relationship and at least one activated resource in the corresponding resource group.

The second mapping relationship may be preset or configured, for example, the second mapping relationship may be preset in the first device and the second device. Device, or the first mapping relationship can be configured by the first device to the second device, or the first mapping relationship can be configured by the second device to the first device; or the second mapping relationship can be agreed upon by the protocol.

Alternatively, both the first device and the second device may generate the second mapping relationship according to the second matrix. Exemplarily, both the first device and the second device may generate activation vectors corresponding to each information state of the N′ bits of information in the second mapping relationship according to the second matrix. The second matrix may include elements of N′ rows by M′ columns. The second matrix is similar to the first matrix. The second matrix may include a first sub-matrix and a second sub-matrix, which will not be described in detail for the sake of brevity. The activation vector is used to indicate at least one activated resource in the resource group. The generation process of the second mapping relationship is similar to the generation process of the first mapping relationship, which will not be described in detail for the sake of brevity. In some embodiments, the first device and/or the second device may also generate activation vectors corresponding to each information state of the N′ bits of information in the second mapping relationship according to the second matrix and the second vector, and the second vector is a 1 by M′ dimensional vector.

Method 2: The first device determines the activation vector of the second information according to the second matrix. In this method 2, the process of the first device determining the activation vector of the second information according to the second matrix is similar to the process of the first device determining the activation vector of the first information according to the first matrix in the above embodiment 1, and will not be repeated for the sake of brevity.

In the above-mentioned method 2, the demodulation process of the first information by the second device is consistent with the demodulation process in the above-mentioned method 1, which will not be described again for the sake of brevity.

In addition, in the above-mentioned method 2, the second device can also directly demodulate the second information according to the second matrix (or based on the second matrix and the second vector) and the m activation resources. The demodulation process can be the inverse process of the first device determining the activation resources of the second information based on the second matrix (or based on the second matrix and the second vector).

In the above-mentioned third embodiment, the first device may also send the second indication information to the second device; accordingly, the second device receives the second indication information sent by the first device, so that the second device demodulates the first information according to the second indication information, or demodulates each second information in the first information according to the second indication information, see S240 in Figure 4. It should be noted that the embodiment of the present application does not limit the execution order between S240 and S210.

Exemplarily, the second indication information may be used to indicate K resource groups and candidate resources included in each of the K resource groups.

In some embodiments, the second indication information may further include at least one of the following:

Second matrix;

The second vector;

The number of candidate resources M′;

The number of bits of the second information is N'.

Optionally, the information not indicated in the second indication information may be preset information, preconfigured information or information agreed upon by a protocol. For example, the second vector may be agreed upon by a protocol, in which case, the second vector does not need to be indicated by the second indication information.
