Description

Information sending and receiving method and device

Technical Field

The embodiment of the invention relates to the communication technology, in particular to an information sending and receiving method and device.

Background

In the early stage of the 4th Generation mobile communication technology (abbreviated as 4G) Long Term Evolution (LTE) system, the user bandwidth needs to be greater than or equal to the system bandwidth to access the serving base station. In the subsequent LTE evolution process, as the service requirement of the ue is gradually refined, the user bandwidth of some low-cost Machine-Type Communication (MTC) terminals may be smaller than the system bandwidth.

In the prior art, a base station generally uses a constant bandwidth to transmit information, and if a user bandwidth is smaller than the constant bandwidth, a user equipment cannot receive the information. At this time, the base station needs to separately transmit a set of information for the bandwidth of the ue, so that the narrowband user can receive the information.

However, in the prior art, since the base station needs to transmit information to the broadband user and the narrowband user respectively, the transmission efficiency of the information is low.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The techniques described herein may be used in various communication systems, such as current 3G, 4G communication systems and next generation communication systems, such as Global System for Mobile communications (GSM), Code Division Multiple Access (Code Division Multiple Access; CDMA) systems, Time Division Multiple Access (TDMA) systems, Wideband Code Division Multiple Access (Wideband Code Division Multiple Access) systems, WCDMA systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, FDMA systems, general packet Radio Service (general packet Radio Service; GPRS) systems, and other LTE systems.

Fig. 1 is a flowchart illustrating a first method for sending information according to an embodiment of the present invention. The embodiment of the invention provides an information sending method, which can be executed by any device for executing the information sending method, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a sending device, and the sending device may be, for example, a network device. As shown in fig. 1, the method of this embodiment may include:

step 101: the transmitting device divides the information to be transmitted into at least two information blocks.

In this embodiment, the transmitting device may divide information to be transmitted into X information blocks. The information block may consist of information bits to be transmitted or channel coded bits or modulation symbols. For example, the sending device may divide information bits to be sent into information blocks and then perform channel coding and modulation on the information blocks, may perform channel coding on information to be sent first, divide bits after channel coding into information blocks, and then modulate each information block, and may further divide modulation symbols into information blocks after channel coding and modulation are performed on information to be sent. The sending device may divide the information to be sent by an equal division manner, and certainly, may also divide the information to be sent by other manners, and for a specific division manner, this embodiment is not limited herein.

Step 102: the sending equipment maps a first part of information blocks in at least two information blocks on a first frequency domain resource on a first time domain resource, and maps a second part of information blocks on a second frequency domain resource on the first time domain resource; wherein the first frequency domain resources are different from the second frequency domain resources; the second partial information block is the other information block of the at least two information blocks except the first partial information block.

In this embodiment, fig. 2 is a schematic diagram of a transmitting device mapping information blocks to time domain resources and frequency domain resources, and as shown in fig. 2, after dividing an information block into at least two information blocks, the transmitting device divides the information blocks into two parts, maps a first part of the information blocks to first frequency domain resources on first time domain resources, and maps a second part of the information blocks except the first part of the information blocks to second frequency domain resources on the first time domain resources. Thus, for a broadband receiving device having a bandwidth greater than or equal to the largest portion of the bandwidth of all signals, it will be able to receive all signals on the first time domain resource. The signal bandwidth is the width of the frequency domain resource occupied by the actual transmission signal corresponding to the information block in transmission.

Step 103: the sending equipment maps the second part information block on the first frequency domain resource on the second time domain resource; wherein the second time domain resource is different from the first time domain resource; the first frequency domain resource on the first time domain resource is the same as the frequency domain resource occupied by the first frequency domain resource on the second time domain resource.

In this embodiment, as shown with continued reference to fig. 2, the sending device further needs to map the second partial information block on the first frequency domain resource on the second time domain resource for sending, so that for a narrowband receiving device having a receiving bandwidth smaller than the maximum part of all signal bandwidths and larger than the minimum part of all signal bandwidths, complete information can be received by continuously receiving the information block. Fig. 3 is a schematic diagram of signal bandwidths, a horizontal axis in fig. 3 corresponds to time, a vertical axis in fig. 3 corresponds to frequency, as shown in fig. 3, a first bandwidth is a maximum portion of all the signal bandwidths, and a second bandwidth is a minimum portion of all the signal bandwidths.

Step 104: the sending device sends the information block on a first frequency domain resource on the first time domain resource, a second frequency domain resource on the first time domain resource and a first frequency domain resource on the second time domain resource respectively.

In this embodiment, after mapping each information block on different time domain resources and frequency domain resources, the sending device sends each information block on each time domain resource and frequency domain resource to the receiving device.

In addition, the sending device may further divide the information to be sent into four blocks, five blocks, six blocks, eight blocks, or the like, and certainly, in practical applications, the information to be sent may also be divided into other block numbers, where the number of the information blocks may be selected according to experience or practical situations, and the specific value of the number of the information blocks is not limited herein.

The following specifically explains an example that a sending device divides information to be sent into four blocks, where fig. 4 is a first schematic diagram of mapping time-frequency resources of the information block to be sent, and a horizontal axis in fig. 4 corresponds to time and a vertical axis corresponds to frequency. Fig. 4 shows the placement positions of the information blocks on the time-frequency resources, where the information blocks in a column are sent at the same time, and the information blocks in a row are distributed in the same frequency-domain resource and different time-domain resources. Those skilled in the art will understand that the information block No. 4 at the bottom left of the figure is the first part information block in fig. 2, and the information blocks No. 1, No. 2 and No. 3 at the top left and bottom right are the second part information blocks in fig. 2. As shown in fig. 4, for a receiving device with a receiving bandwidth greater than or equal to the first bandwidth, complete information can be received after receiving the first time domain resource once, and information blocks other than the first time domain resource can also be continuously received to increase the reliability of demodulation and decoding of the received signal. For a receiving device with a receiving bandwidth greater than or equal to the second bandwidth, four information blocks may be continuously received on the first frequency domain resource on the first time domain resource and the second time domain resource, that is, complete information may be received. It can be seen that a receiving device with a wider receiving bandwidth (hereinafter referred to as a wideband receiving device) can receive the complete information in a shorter time, and a receiving device with a narrower receiving bandwidth (hereinafter referred to as a narrowband receiving device) can receive the complete information by continuously receiving the information block for a longer time.

Fig. 5 is a schematic diagram of time-frequency resource mapping of an information block to be sent, and referring to fig. 4 and fig. 5, in fig. 5, the vertical direction is frequency domain distribution and the horizontal direction is time domain distribution, and the specific distribution form is similar to fig. 4 and will not be described again below. As shown in fig. 5, after the information block is sent in different time domain resources and frequency domain resources, for different receiving devices receiving the broadband, complete information can be received by receiving the information block in different time domain resources and frequency domain resources. For example: for the broadband receiving device, the complete information can be received in a short time, for example, in the duration of one information block, and for the narrowband receiving device, the complete information can be received in a narrow frequency domain resource, for example, in the frequency domain resource occupied by one information block, by increasing the duration of the receiving time, so that the phenomenon that the transmitting device needs to independently transmit information respectively for receiving devices with different receiving bandwidths in the prior art is avoided, and the efficiency of information transmission can be improved. It should be noted that, the present invention is not limited to the specific time-frequency mapping methods shown in fig. 4 and fig. 5, and any sending device maps a first part of information blocks of at least two information blocks on a first frequency domain resource on a first time domain resource, maps a second part of information blocks on a second frequency domain resource on the first time domain resource, and maps the second part of information blocks on the first frequency domain resource on a second time domain resource, so that a receiving device can satisfy a mapping method that can obtain complete information by receiving any row or any column of information blocks or by continuous reception using a receiving bandwidth narrower than a maximum signal bandwidth.

Fig. 6 is a diagram illustrating a transmitting apparatus transmitting a signal using the signal mapping method shown in fig. 4. As shown in fig. 6, the transmitting device periodically transmits the information to be transmitted in the time domain. Each time information to be transmitted is called a transmission sample of the information to be transmitted. In the method shown in fig. 6, each transmission sample contains complete information, and the relative positions of the at least two information blocks on the time-frequency resource in each transmission sample are the same. Both the broadband receiving terminal and the narrowband receiving terminal can obtain complete information by receiving an information block in one transmission sample, and can also improve the reliability of demodulation and decoding of a received signal by accumulatively receiving a plurality of transmission samples.

In the information sending method provided in the embodiment of the present invention, a sending device divides information to be sent into at least two information blocks, maps a first part of the at least two information blocks on a first frequency domain resource on a first time domain resource, maps a second part of the information blocks on a second frequency domain resource on the first time domain resource, maps the second part of the information blocks on a first frequency domain resource on a second time domain resource, and sends the information blocks on the first frequency domain resource on the first time domain resource, the second frequency domain resource on the first time domain resource, and the first frequency domain resource on the second time domain resource, respectively. The sending equipment maps the information blocks on the first frequency domain resource on the first time domain resource, the second frequency domain resource on the first time domain resource and the first frequency domain resource on the second time domain resource respectively, so that for the broadband receiving equipment, complete information can be received in a short time, such as the duration of one information block, and for the narrowband receiving equipment, all signals can be received on the narrower frequency domain resource, such as the frequency domain resource occupied by one information block, by increasing the continuous receiving time, the phenomenon that the sending equipment needs to independently send information respectively for the receiving equipment with different receiving bandwidths in the prior art is avoided, and the information sending efficiency can be improved.

Optionally, on the basis of the embodiment shown in fig. 2, the sending device may further send a fourth partial information block on a fifth frequency domain resource of the third time domain resource, where the fourth partial information block includes an information block that enables the receiving device to receive complete information on the first frequency domain resource and the second frequency domain resource on the first time domain resource, and also may receive complete information on the first frequency domain resource and the fifth frequency domain resource on the first time domain resource and the third time domain resource.

Specifically, fig. 7 is another schematic diagram of the sending device mapping the information block to the time domain resource and the frequency domain resource, as shown in fig. 7, after the sending device divides the information block, the sending device maps the first part of the information block to the first frequency domain resource on the first time domain resource, maps the second part of the information block to the second frequency domain resource on the first time domain resource, maps the second part of the information block to the first frequency domain resource on the second time domain resource, and maps the fourth part of the information block to the fifth frequency domain resource on the third time domain resource. In this way, for a wideband receiving device, that is, a device whose receiving bandwidth is greater than that of the device capable of supporting simultaneous reception of the first frequency domain resource and the second frequency domain resource, all signals may be received on the first time domain resource, and for a narrowband receiving device, that is, a device whose receiving bandwidth is greater than that of the first frequency domain resource or the first frequency domain resource and the fifth frequency domain resource, all signals may be obtained on the first frequency domain resource in a manner of continuously receiving the information block on the first time domain resource, or may be obtained on the first frequency domain resource and the fifth frequency domain resource in a manner of continuously receiving the information block on the first time domain resource and the second time domain resource. Therefore, the phenomenon that the sending equipment needs to respectively and independently send information aiming at the receiving equipment with different receiving bandwidths in the prior art is avoided, and the information sending efficiency can be improved.

Next, the information to be sent is divided into four blocks by a sending device, which is specifically described as an example, where fig. 8 is a first schematic diagram of mapping time-frequency resources of the information block to be sent, a horizontal axis in fig. 8 corresponds to time, and a vertical axis corresponds to frequency, and fig. 8 shows the placement positions of the information blocks on the time-frequency resources, where information blocks in a column are to be sent at the same time, information blocks in a row are to be distributed in the same frequency-domain resource and different time-domain resources, and each block with a sequence number represents an information block with a corresponding sequence number. Those skilled in the art will understand that the information block No. 4 in the lower left corner of fig. 8 may be the first partial information block in fig. 7, the information block No. 1, the information block No. 3 and the information block No. 2 in the upper left corner of the first column and the right part of the last row in the lower right corner of fig. 8 may be the second partial information block in fig. 7, and the information block No. 2 in the third row of fig. 8 may be the fourth partial information block in fig. 7. By using the information block time-frequency mapping method shown in fig. 8, for a receiving device with a receiving bandwidth greater than or equal to the first bandwidth, complete information can be received after receiving the information once on the first time domain resource, and information blocks other than the first time domain resource can also be continuously received to increase the reliability of demodulation and decoding of the received signal. For a receiving device with a receiving bandwidth greater than or equal to the second bandwidth, four information blocks may be continuously received on the first frequency domain resource on the first time domain resource and the second time domain resource to obtain complete information, or all information blocks may be continuously received on the first frequency domain resource and the fifth frequency domain resource on the first time domain resource and the third time domain resource to obtain complete information.

Fig. 9 is a schematic diagram of time-frequency resource mapping of an information block to be sent, and referring to fig. 8 and fig. 9, in fig. 9, the vertical direction is frequency domain distribution and the horizontal direction is time domain distribution, and the specific distribution form is similar to fig. 8 and will not be described again below. As shown in fig. 9, after the information block is sent in different time domain resources and frequency domain resources, for different receiving devices receiving the broadband, complete information can be received by receiving the information block in different time domain resources and frequency domain resources. For example: for a broadband receiving device, complete information can be received within a short time, for example, within the duration of one information block, and for a narrowband receiving device, complete information can be received on a narrower frequency domain resource, for example, the frequency domain resource occupied by one information block or the frequency domain resource occupied by two information blocks, by increasing the duration of receiving time, which avoids the phenomenon that a transmitting device in the prior art needs to transmit information separately for receiving devices with different receiving bandwidths, thereby improving the efficiency of information transmission. It should be noted that the present invention is not limited to the specific time-frequency mapping methods shown in fig. 8 and fig. 9, and any mapping method that can satisfy the requirement that the sending device maps a first partial information block of at least two information blocks on a first frequency domain resource on a first time domain resource, maps a second partial information block on a second frequency domain resource on the first time domain resource, maps the second partial information block on the first frequency domain resource on a second time domain resource, and maps a fourth partial information block on a fifth frequency domain resource on a third time domain resource is included in the present invention, so that the receiving device can obtain complete information by receiving any row or any column of information blocks or by continuous reception using a receiving bandwidth narrower than the maximum signal bandwidth.

In the information sending method provided in the embodiment of the present invention, the first part of the information blocks is mapped on the first frequency domain resource on the first time domain resource, the second part of the information blocks is mapped on the second frequency domain resource on the first time domain resource, the second part of the information blocks is mapped on the first frequency domain resource on the second time domain resource, and the fourth part of the information blocks is mapped on the fifth frequency domain resource on the third time domain resource, so that the receiving devices with different receiving bandwidths flexibly select different receiving modes, thereby avoiding a phenomenon that the sending device in the prior art needs to send information separately for the receiving devices with different receiving bandwidths, and thus improving the efficiency of information sending.

Optionally, on the basis of the embodiment shown in fig. 1, before the sending device sends the information block on the first frequency domain resource on the first time domain resource, on the second frequency domain resource on the first time domain resource, and on the first frequency domain resource on the second time domain resource, respectively, the sending device further includes: mapping the third partial information block on a second frequency domain resource of a second time domain resource; the second frequency domain resources on the first time domain resources are the same as the frequency domain resources occupied by the second frequency domain resources on the second time domain resources, and the third part of information blocks are information blocks at least comprising the first part of information blocks in at least two information blocks.

Specifically, fig. 10 is another schematic diagram of the sending device mapping the information blocks to the time domain resources and the frequency domain resources, as shown in fig. 10, the sending device may further map a third portion of the information blocks on a second frequency domain resource of a second time domain resource, and the sending device will send the information blocks on the first frequency domain resource on the first time domain resource, the second frequency domain resource on the first time domain resource, the first frequency domain resource on the second time domain resource, and the second frequency domain resource of the second time domain resource, respectively. Wherein the third partial information block is an information block including at least the first partial information block among the at least two information blocks. Thus, for a broadband receiving device, that is, a device whose receiving bandwidth is greater than that of the device capable of supporting receiving the first frequency domain resource and the second frequency domain resource simultaneously, complete information can be received and obtained in the first time domain resource or the second time domain resource, and for a narrowband receiving device, that is, a device whose receiving bandwidth is greater than that of the first frequency domain resource or the second frequency domain resource, all signals can be obtained on the first frequency domain resource or the second frequency domain resource in a manner of continuously receiving information blocks on the first time domain resource and the second time domain resource, thereby avoiding a phenomenon that a transmitting device needs to independently transmit information respectively for receiving devices with different receiving bandwidths in the prior art, and thus, improving the efficiency of information transmission.

Next, the information to be transmitted is divided into two information blocks by the transmitting device, which is specifically described as an example, where fig. 11 is a first schematic diagram of mapping time-frequency resources of the information block to be transmitted, a horizontal axis in fig. 11 corresponds to time, and a vertical axis corresponds to frequency, and each square with a sequence number represents an information block with a corresponding sequence number. The matrix in the figure is the placement position of the information blocks on the time-frequency resources, wherein the information blocks in each column are sent at the same time, and the information blocks in each row are distributed in the same frequency domain resources and different time domain resources. Those skilled in the art will understand that the information block No. 1 in the lower left corner of fig. 11 may be the first part information block in fig. 10, the information block No. 2 in the upper left corner and the lower right corner of fig. 11 may be the second part information block in fig. 10, and the information block No. 1 in the upper right corner of fig. 11 may be the third part information block in fig. 10, that is, in the example shown in fig. 11, the first part information block and the third part information block are the same. As shown in fig. 11, for the narrowband receiving device with the first bandwidth, all information blocks can be obtained by continuous reception in time on the frequency domain resource where any row of information blocks is located to obtain complete information. And for the broadband receiving equipment with the second bandwidth, all the information blocks can be obtained by receiving the broadband receiving equipment at one time on the time domain resources where any column of information blocks are located.

To illustrate the information to be transmitted is divided into four blocks by the transmitting device, wherein fig. 12 is a schematic diagram of mapping time-frequency resources of the information block to be transmitted, a horizontal axis in fig. 12 corresponds to time, a vertical axis corresponds to frequency, and each block with sequence numbers represents the information block with corresponding sequence numbers. Those skilled in the art will understand that the information block No. 4 in the lower left corner of fig. 12 may be the first part information block in fig. 10, the information blocks No. 1, No. 3 and No. 2 in the upper left corner of fig. 12 in the upper first column and the right part of the last row in the lower right corner may be the second part information block in fig. 10, and the information blocks 9 in the upper right corner of fig. 12 except the first column and the last row may be the third part information block in fig. 10, that is, in the example shown in fig. 12, the third part information block contains the first part information block and some other information blocks. By using the information block time-frequency mapping method shown in fig. 12, the narrowband receiving device can continuously receive information in any row shown in the figure, that is, in the frequency domain resource where any row of information blocks is located, and obtain all information blocks to obtain complete information; the broadband receiving device may implement one-time reception in any column shown in the figure, that is, in the time domain resource where information blocks in any column are located, with a reception bandwidth larger than the frequency domain where all information blocks are located, and obtain all information blocks to obtain complete information. Further, the receiving device may also use a receiving bandwidth larger than the frequency domain resource where the two adjacent information blocks are located to continuously receive in the time domain resource occupied by the two adjacent information blocks, so as to obtain complete information.

Fig. 13 is a third schematic diagram of mapping of time-frequency resources of an information block to be sent, and referring to fig. 12 and 13, a vertical direction in fig. 13 is frequency domain distribution, and a horizontal direction is time domain distribution, and a specific distribution form is similar to that in fig. 12 and will not be described again below. As shown in fig. 13, the sending device may further divide the information to be sent into five blocks, six blocks, eight blocks, and the like, and map the information blocks on the time-frequency resources by the method shown in the drawing, so that the receiving device can continuously receive the information blocks in any row shown in the drawing, that is, in the frequency-domain resources where the information blocks in any row are located, and obtain all the information blocks to obtain complete information; the receiving device may perform one-time reception on the time domain resources in any column shown in the figure, that is, in the time domain resources in which information blocks in any column are located, with a reception bandwidth larger than the frequency domain in which all information blocks are located, and obtain all information blocks to obtain complete information. Further, the receiving device may further obtain the complete information through proper continuous reception using a reception bandwidth larger than the frequency domain resource where one information block is located and smaller than the frequency domain resource where the maximum number of information blocks is located. Therefore, the invention provides a flexible signal transmission method, so that receiving equipment with different receiving bandwidth capabilities can utilize complete information of different receiving time. It should be noted that, the present invention is not limited to the specific time-frequency mapping methods shown in fig. 11 to fig. 13, and any mapping method that can satisfy the requirement that the sending device maps a first part of information blocks of at least two information blocks on a first frequency domain resource on a first time domain resource, maps a second part of information blocks on a second frequency domain resource on the first time domain resource, maps the second part of information blocks on the first frequency domain resource on a second time domain resource, and maps a third part of information blocks on the second frequency domain resource on the second time domain resource is included in the present invention, so that the receiving device can obtain complete information by receiving any row or any column of information blocks.

Fig. 14 is a diagram illustrating a transmitting apparatus transmitting a signal using the signal mapping method shown in fig. 12. The transmitting device transmits the signal of fig. 12 periodically, each time transmitting one column of the signal of fig. 12, i.e. one sample of the complete information. The broadband receiving terminal can obtain complete information by receiving one sample, and can also receive a plurality of samples to increase the reliability of demodulation and decoding after receiving. The narrowband terminal can obtain complete information by continuously receiving on the frequency domain resource where one or several continuous signal blocks are located.

In the information sending method provided in the embodiment of the present invention, the sending device maps the information blocks on the first frequency domain resource on the first time domain resource, the second frequency domain resource on the first time domain resource, the first frequency domain resource on the second time domain resource, and the second frequency domain resource on the second time domain resource, respectively, so that the receiving devices with different receiving bandwidth capabilities can obtain complete information by receiving any row or any column of information blocks, thereby avoiding a phenomenon that the sending device needs to send information separately for the receiving devices with different receiving bandwidths in the prior art, and thus improving the efficiency of information sending.

Optionally, on the basis of the embodiment shown in fig. 1, the second frequency domain resources on the first time domain resources include third frequency domain resources and fourth frequency domain resources; mapping the second partial information block on a second frequency domain resource on the first time domain resource, including: the sending equipment maps a part of information blocks in the second part of information blocks on third frequency domain resources and maps the rest information blocks in the second part of information blocks on fourth frequency domain resources; the third frequency domain resource is positioned on the side, with larger frequency, of the first frequency domain resource on the first time domain resource, and the fourth frequency domain resource is positioned on the side, with smaller frequency, of the first frequency domain resource on the first time domain resource; the rest information blocks are other information blocks except for a part of information blocks in the second part of information blocks.

Specifically, fig. 15 is another schematic diagram of the sending device mapping information blocks to time domain resources and frequency domain resources, as shown in fig. 15, the sending device may divide a second part of information blocks into a part of information blocks and remaining information blocks, so that the sending device may map the part of information blocks on a third frequency domain resource on the first time domain resource and map the remaining information blocks on a fourth frequency domain resource on the first time domain resource, and after the mapping is completed, the sending device will send the information blocks on the first frequency domain resource on the first time domain resource, the third frequency domain resource and the fourth frequency domain resource on the first time domain resource, the first frequency domain resource on the second time domain resource, and the second frequency domain resource on the second time domain resource, respectively. In this way, the wideband receiving device may receive all signals on the first time domain resource, and the narrowband receiving device may receive the complete information in a manner that the narrowband receiving device continuously receives the information block on the first time domain resource and the first frequency domain resource on the second time domain resource.

Next, the information to be sent is still specifically described by taking an example that the sending device divides the information to be sent into four blocks, where fig. 16 is a first schematic diagram of mapping time-frequency resources of the information block to be sent, and a horizontal axis in fig. 16 corresponds to time and a vertical axis corresponds to frequency. Fig. 16 shows the placement positions of the information blocks on the time-frequency resources, where the information blocks in a column are to be transmitted at the same time, and the information blocks in a row are to be distributed in the same frequency-domain resources and different time-domain resources. Those skilled in the art will understand that the information block No. 2 in the left column in fig. 16 is the first part information block in fig. 15, the information block No. 1, the information block No. 3 and the information block No. 4 on the right side of the same row are the second part information blocks in fig. 15, the information block No. 1 in the left column is a part of the information blocks contained in the second part information blocks in fig. 15, and the information block No. 3 and the information block No. 4 in the left column are the rest of the information blocks contained in the second part information blocks in fig. 15. Information block No. 2 in the second line in fig. 16 is the first partial information block in fig. 15, and information block No. 1, information block No. 4, and information block No. 3 in the second line are the second partial information blocks in fig. 15. As shown in fig. 16, the broadband receiving device may receive the complete information in a shorter time, e.g., the duration of the first column in the figure, while the narrowband receiving device may receive the complete information by continuously receiving the information block in a longer time, e.g., the duration of the second row in the figure.

Optionally, on the basis of the embodiment shown in fig. 15, the sending device may further map a fourth partial information block on a fifth frequency domain resource of the third time domain resource, where the fourth partial information block includes an information block that enables the receiving device to obtain complete information through receiving on the fifth frequency domain resource and the first frequency domain resource on the first time domain resource and the third time domain resource.

Specifically, fig. 17 is another schematic diagram of the sending device mapping the information block to the time domain resource and the frequency domain resource, as shown in fig. 17, the sending device may further map a fourth portion of the information block on a fifth frequency domain resource of a third time domain resource, and the sending device will send the information block on the first frequency domain resource on the first time domain resource, on the third frequency domain resource and the fourth frequency domain resource on the first time domain resource, on the first frequency domain resource on the second time domain resource, and on the fifth frequency domain resource of the third time domain resource, respectively. In this way, for a wideband receiving device, that is, a device whose receiving bandwidth is greater than that of the device capable of supporting simultaneous reception of the first frequency domain resource, the third frequency domain resource, and the fourth frequency domain resource, complete information may be obtained by reception in the first time domain resource, and for a narrowband receiving device, that is, a device whose receiving bandwidth is greater than that of the first frequency domain resource or that of the first frequency domain resource and the fifth frequency domain resource, all signals may be obtained by continuously receiving information blocks in the first time domain resource and the second time domain resource on the first frequency domain resource, or may be obtained by continuously receiving information blocks in the first time domain resource and the third time domain resource on the first frequency domain resource and the fifth frequency domain resource. Therefore, the phenomenon that the sending equipment needs to respectively and independently send information aiming at the receiving equipment with different receiving bandwidths in the prior art is avoided, and the information sending efficiency can be improved.

Next, the information to be sent is still specifically described by taking an example that the sending device divides the information to be sent into four blocks, where fig. 18 is a schematic diagram of mapping time-frequency resources of the information block to be sent, and a horizontal axis in fig. 18 corresponds to time and a vertical axis corresponds to frequency. Fig. 18 shows the placement of information blocks on time-frequency resources, where information blocks in a column are to be transmitted at the same time, and information blocks in a row are to be distributed in the same frequency-domain resource and different time-domain resources. Those skilled in the art will understand that the information block No. 2 in the left column in fig. 18 is the first partial information block in fig. 17, the information block No. 1, the information block No. 3 and the information block No. 4 on the right side of the same row are the second partial information blocks in fig. 17, the information block No. 1 in the left column is a part of the information blocks contained in the second partial information block in fig. 17, the information block No. 3 and the information block No. 4 in the left column are the rest of the information blocks contained in the second partial information block in fig. 17, and the information block No. 1 in the third row and the second column is the fourth partial information block in fig. 17. As shown in fig. 18, the broadband receiving device may receive the complete information in a shorter time, e.g., the duration of the first column in the figure, while the narrowband receiving device may receive the complete information by continuously receiving the information block in a longer time, e.g., the duration of the second row in the figure. In addition, the receiving device may receive the complete information with a receiving bandwidth larger than two continuous information block bandwidths, for example, as shown in fig. 18, the receiving device may receive the second row first column information block and the second row second column information block and the third row first column information block and the third row second column information block to obtain the complete information.

Optionally, on the basis of the embodiment shown in fig. 15, the sending device may further divide the fourth partial information block into two parts, which are a part of the fourth partial information block and the rest of the fourth partial information block, respectively, where the part of the fourth partial information block may be mapped on the sixth frequency domain resources of the third time domain resources, and the rest of the fourth partial information block may be mapped on the fifth frequency domain resources of the third time domain resources.

Specifically, fig. 19 is another schematic diagram of the sending device mapping the information blocks to the time domain resources and the frequency domain resources, as shown in fig. 19, the sending device may further map a part of the information blocks of the fourth part of the information blocks on sixth frequency domain resources of third time domain resources, map the rest of the information blocks of the fourth part of the information blocks on fifth frequency domain resources of the third time domain resources, and send the information blocks on the first frequency domain resources on the first time domain resources, on the third frequency domain resources and the fourth frequency domain resources on the first time domain resources, on the first frequency domain resources on the second time domain resources, and on the fifth frequency domain resources and the sixth frequency domain resources on the third time domain resources, respectively. In this way, for a wideband receiving device, that is, a device whose receiving bandwidth is greater than that of the device capable of supporting simultaneous reception of the first frequency domain resource, the third frequency domain resource, and the fourth frequency domain resource, complete information may be obtained by reception in the first time domain resource, and for a narrowband receiving device, that is, a device whose receiving bandwidth is greater than that of the first frequency domain resource or the first frequency domain resource, the fifth frequency domain resource, and the sixth frequency domain resource, all signals may be obtained by continuously receiving information blocks in the first time domain resource and the second time domain resource on the first frequency domain resource, or by continuously receiving information blocks in the first time domain resource and the third time domain resource on the first frequency domain resource, the fifth frequency domain resource, and the sixth frequency domain resource. Therefore, the phenomenon that the sending equipment needs to respectively and independently send information aiming at the receiving equipment with different receiving bandwidths in the prior art is avoided, and the information sending efficiency can be improved.

Next, the information to be sent is still specifically described by taking an example that the sending device divides the information to be sent into four blocks, where fig. 20 is a schematic diagram of mapping time-frequency resources of the information block to be sent, and a horizontal axis in fig. 20 corresponds to time and a vertical axis corresponds to frequency. Fig. 20 shows the placement positions of the information blocks on the time-frequency resources, where the information blocks in a column are to be transmitted at the same time, and the information blocks in a row are to be distributed in the same frequency-domain resources and different time-domain resources. Those skilled in the art will understand that the information block No. 2 in the left column in fig. 20 is the first partial information block in fig. 19, the information block No. 1 and the information block No. 3 and the information block No. 4 on the right side of the same row are the second partial information blocks in fig. 19, the information block No. 1 in the left column is a part of the information blocks contained in the second partial information block in fig. 19, the information block No. 3 and the information block No. 4 in the left column are the rest of the information blocks contained in the second partial information block in fig. 19, the information block No. 4 in the first row and the second column is a part of the information blocks in the fourth partial information block in fig. 19, and the information block No. 1 in the third row and the second column is the rest of the information blocks in the fourth partial information block in fig. 19. As shown in fig. 20, the broadband receiving device may receive the complete information in a shorter time, e.g., the duration of the first column in the figure, while the narrowband receiving device may receive the complete information by continuously receiving the information block in a longer time, e.g., the duration of the second row in the figure. Besides, the receiving device may also receive the complete information with a receiving bandwidth larger than two continuous information block bandwidths, for example, as shown in fig. 20, the receiving device may receive the second row first column information block and the second row second column information block and the third row first column information block and the third row second column information block to obtain the complete information, and may also receive the first row first column information block and the first row second column information block and the second row first column information block and the second row second column information block to obtain the complete information.

Fig. 21 is a schematic diagram of time-frequency resource mapping of an information block to be transmitted, and referring to fig. 18, 20 and 21, a vertical direction in fig. 21 is frequency domain distribution, and a horizontal direction in fig. 21 is time domain distribution, and a specific distribution form is similar to that in fig. 18 and 20, and will not be described again below. As shown in fig. 21, the sending device may further divide the information to be sent into six blocks, eight blocks, etc., and map the information blocks on the time-frequency resources in the method shown in the figure, so that the receiving devices with different receiving bandwidth capabilities may utilize different receiving times to receive the complete information. The receiving device can continuously receive the information blocks in any row shown in the figure, namely, the frequency domain resources where the information blocks in any row are located, and all the information blocks are obtained to obtain complete information; the receiving device may perform one-time reception on the time domain resources in any column shown in the figure, that is, in the time domain resources in which information blocks in any column are located, with a reception bandwidth larger than the frequency domain in which all information blocks are located, and obtain all information blocks to obtain complete information. It should be noted that the present invention is not limited by the specific time-frequency mapping methods shown in fig. 18, 20, and 21, and any method can be satisfied that the transmitting apparatus maps a first part of information blocks of at least two information blocks on a first frequency domain resource on the first time domain resource, maps a part of information blocks of a second part of information blocks on a third frequency domain resource on the first time domain resource, maps the rest of information blocks of the second part of information blocks on a fourth frequency domain resource on the first time domain resource, maps the second part of information blocks on the first frequency domain resource on the second time domain resource, maps a fourth part of information blocks on a fifth frequency domain resource on the third time domain resource, or maps a first part of information blocks of at least two information blocks on a first frequency domain resource on the first time domain resource, maps a part of information blocks of the second part of information blocks on a third frequency domain resource on the first time domain resource, mapping the rest information blocks of the second part information blocks on the fourth frequency domain resource on the first time domain resource, mapping the second part information blocks on the first frequency domain resource on the second time domain resource, mapping a part of information blocks of the fourth part information blocks on the sixth frequency domain resource on the third time domain resource, and mapping the rest information blocks of the fourth part information blocks on the fifth frequency domain resource on the third time domain resource, so that the mapping method that the receiving device can receive any row or any column of information blocks to obtain complete information is included in the present invention.

Fig. 22 is a schematic diagram of a transmitting device transmitting a signal by using the signal mapping method shown in fig. 17, and as shown in fig. 22, the transmitting device periodically transmits the information to be transmitted in the time domain. Each time information to be transmitted is called a transmission sample of the information to be transmitted. In the method shown in fig. 22, each transmission sample contains complete information, and the relative positions of the at least two information blocks on the time-frequency resource in each transmission sample are the same. Both the broadband receiving terminal and the narrowband receiving terminal can obtain complete information by receiving an information block in one transmission sample, and can also improve the reliability of demodulation and decoding of a received signal by accumulatively receiving a plurality of transmission samples.

In addition, it should be noted that the different time domain resources mentioned in the present invention may be continuous in the time domain, for example, the information blocks are transmitted in continuous symbols, time slots, or subframes, or may be discontinuous in the time domain, for example, several symbols, time slots, or subframes are used as cycles, and each transmission only occupies one or a part of the symbols, time slots, or subframes. Similarly, in the frequency domain, the frequency domain resources occupied by each information block may be continuous, for example, occupy several frequency domain subcarriers, subcarrier groups, resource blocks, or resource block groups, or may be discontinuous, for example, several subcarriers, one or several resource blocks, or one or several resource block groups are used as periods, and each period only occupies one or a part of the frequency domain resources for transmission. Of course, in the description of whether the time-frequency resources are continuous or not, the present invention is not limited to the examples given above.

In the information sending method provided by the embodiment of the present invention, the sending device maps the information blocks on the first frequency domain resource on the first time domain resource, the second frequency domain resource on the first time domain resource, the third frequency domain resource on the first time domain resource, and the first frequency domain resource on the second time domain resource, respectively, so that the broadband receiving device can receive the complete information at a certain transmission time, and the narrowband receiving device can receive the complete information in a manner that the receiving bandwidth of the frequency domain resource larger than that of any information block is in a proper frequency domain position and the information block is continuously received, thereby avoiding a phenomenon that the sending device needs to send information respectively for receiving devices with different bandwidths in the prior art, and improving the efficiency of information sending.

Optionally, on the basis of the foregoing embodiments, all or part of the time-frequency resources include other signals except the information block; the time frequency resources comprise time domain resources and frequency domain resources.

The other signal may be a demodulation pilot signal of the information block, or may be other identification signals. Fig. 23 is a schematic diagram of a transmitting device mapping an information block and other signals to time-frequency domain resources, and as shown in fig. 23, small blocks in the diagram are other signals except the information block, but the time-frequency resources in which the information block is located are included in the range of the time-frequency resources in which the information block is located. When other signals are demodulation pilot signals of the information block, the mapping sequence of the pilot signals can be irrelevant to the serial number of the information block, so that the complexity of system design can be reduced, namely decoupling information block transmission design and pilot design. It should be noted that the mapping order of the demodulation pilot signals may also be related to the sequence numbers of the information blocks, so that some indication information may be carried, i.e. information is carried by the predefined relationship between the demodulation pilot signals and the information blocks. For example, the demodulation pilot signal may be used to indicate that the signal is within the first transmission sample, that is, the receiving device may confirm the transmission sample number through detection of the pilot signal and accordingly confirm the mapping order of the signal blocks in the transmission samples in the time domain and/or the frequency domain.

In addition, with continued reference to fig. 23, each transmission sample may include only one other signal, or may include at least two other signals, and the types of the other signals may also be various, for example: measurement pilot signals, positioning pilot signals, physical control channel signals, and the like.

It should be noted that other signals are not limited to the information blocks shown in fig. 23, and when the information blocks are transmitted in other manners or the number of the information blocks is other than the number of the information blocks, other signals besides the information blocks may be included in all or part of the time-frequency resources. For example, if the transmission method shown in fig. 6 or fig. 14 is adopted, other signals besides the information block may be included in all or part of the time-frequency resources.

In addition, the specific transmission signals of the information blocks with the same sequence number may be the same or different in different transmission samples. In one example, the transmitting device divides the coded bits or modulated symbols into information blocks, and the transmitted signals of the information blocks with the same sequence number in different transmission samples are the same. In another example, although the transmitting device divides the coded bits or modulated symbols into information blocks, the transmitting device scrambles the signal to be transmitted according to the transmission sample number before retransmitting, and thus the last transmission number is different among different transmission samples. In another example, when the sending device divides information bits to be sent into information blocks and then performs channel coding and modulation on the information blocks respectively, the information blocks with the same sequence number may correspond to different coded bits and corresponding modulation symbols in different transmission samples, similar to different redundancy versions in the LTE system, so that the sending signals of the information blocks with the same sequence number in different transmission samples are different. In another case, although the time-frequency resources allocated to each information block are the same, the resources occupied by other signals in the time-frequency resources are different, in this case, the specific transmission resources used by each block are different, for example, the common signals included in different time scheduling transmission units and different resource blocks are different, and the common signals may be common pilots or common control channels that need to be avoided. In addition, in different transmission samples, the sending device may use time-frequency resources of different sizes according to the system load condition at that time when sending the information blocks with the same sequence number each time, and thus, specific sending signals carried by the time-frequency resources of different sizes may be different.

Besides, the sending device can map the common information required by different types of receiving devices within the receiving bandwidth capacity range. Taking fig. 18 as an example, the receiving devices with three different receiving bandwidth capabilities shown in the figure may be different types of receiving devices, for example, the receiving device with the first bandwidth may be a high-reliable and Low Latency Communication (URLLC) terminal device, the receiving device with the second bandwidth may be an enhanced multimedia BroadBand (eMBB) terminal device, and the receiving device with the third bandwidth may be a Machine-type Communication (MTC) terminal device. The information transmitted by the method of the invention can be common information which needs to be received by different types of receiving equipment together, besides, the transmitting equipment can also simultaneously transmit other common information which needs to be received by different types of receiving equipment respectively. Based on fig. 18, fig. 24 is a diagram illustrating the transmission of other common information. As shown in fig. 24, the information block 5 and the information block 6 are other common information required by the first bandwidth receiving apparatus, the information blocks 7 and 8 are other common information required by the second bandwidth receiving apparatus, and the information block 9 is other common information required by the third bandwidth receiving apparatus. In one example, the common information received in common may be a broadcast channel including a portion of the content and the other common information may be a broadcast channel including a portion of the content, and in one example, the common information received in common may also be a broadcast channel and the other common information may be a portion of the system information.

In the following, the transmission method of the information block in fig. 14 is taken as an example, and how the receiving device receives the information block transmitted by the transmitting device and demodulates each information block will be described in detail. The receiving device may be, for example, a terminal device.

Fig. 25 is a flowchart illustrating an information receiving method according to a first embodiment of the present invention. The embodiment of the invention provides an information receiving method, which can be executed by any device for executing the information receiving method, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a receiving device, and the receiving device may be, for example, a terminal device. As shown in fig. 25, the method of the present embodiment may include:

step 201: the receiving device determines time-frequency resource location information of information blocks in the received signal.

In this embodiment, before demodulating, decoding, and transmitting information sent by a sending device, a receiving device needs to determine a specific number of information blocks in a received signal, and a time-frequency resource position, and a frequency-frequency resource position of the information blocks in the received signal; the information block is obtained by dividing information to be transmitted by the transmitting device before transmission.

Specifically, the specific number of information blocks may be agreed in advance by the transmitting device and the receiving device, for example, as specified by a communication standard, or the transmitting device may also transmit a signaling indication information block number to the receiving device before transmitting the information blocks. For example, in fig. 14, the receiving device can determine that the number of information blocks is 4 by the above-described manner.

The method for the receiving device to determine the time domain resource location of each information block includes the following steps: the first method comprises the following steps: the receiving device and the sending device may agree on the time domain resource location in advance, and in practical application, may agree on the sending period and the time domain resource location occupied by the information block in each period. For example: if the sending information is a Physical Broadcast Channel (PBCH), the receiving device may determine the time domain resource location of the information block of the signal to be received according to the time domain resource location where the detected synchronization signal is located and the relative time domain location of the predetermined synchronization signal and the broadcast signal.

And the second method comprises the following steps: the sending equipment carries the configuration information in the notification message and sends the notification message to the receiving equipment, and the receiving equipment determines the time domain resource position information according to the received configuration information. The configuration information may be time domain resource location information explicitly indicated by the sending device, and at this time, the receiving device may directly determine the time domain resource location according to the configuration information. In addition, the configuration information may also be that the sending device selects one of the possible time domain resource locations from at least one possible time domain resource location pre-agreed by the sending device and the receiving device to indicate to the receiving device, or that the sending device configures more than one possible time domain resource location through a high-level signaling first, and then indicates one of the possible time domain resource locations to the receiving device through a dynamic signaling. The configuration information may be sent to a group of receiving devices, or may be sent to all receiving devices served by the sending device. The specific indication manner of the time domain resource location is not limited in this embodiment.

In addition, the frequency domain resource position is a frequency domain resource position occupied by the information block, for example, a central frequency point and a bandwidth of the frequency domain resource, or a starting subcarrier or a resource block sequence number and a receiving subcarrier or a resource block sequence number of the frequency domain resource, or a resource block sequence number included in the frequency domain resource. The frequency domain resource may also be periodically transmitted on the frequency domain resource of the same time domain resource, in this case, the frequency domain resource position may be the frequency domain period and the frequency domain position of the resource occupied in each period.

The method for the receiving device to determine the frequency domain resource location of each information block includes the following steps: the first method comprises the following steps: the receiving device and the sending device may agree on the frequency domain resource location in advance, and in practical application, may agree on the center frequency point and the bandwidth. For example: if the received signal is a PBCH signal, for the central frequency point, the receiving equipment can determine the position of the central frequency point of the signal to be received according to the frequency domain resource where the detected synchronous signal is located and the relative frequency domain position of the synchronous signal and the broadcast signal which are agreed in advance; for the bandwidth, the receiving device may agree to use its own maximum receiving bandwidth, or may determine the bandwidth according to the previously received synchronization signal, and in a specific implementation process, determining the bandwidth according to the previously received synchronization signal includes that the receiving device may use the same bandwidth as the synchronization signal, or indicate the bandwidth used by the receiving device according to the placement positions of different synchronization signals, or indicate the bandwidth used by the receiving device according to different synchronization signal sequences. The embodiment is not limited herein as to the specific manner how the bandwidth is determined from the previously received synchronization signal.

And the second method comprises the following steps: the receiving equipment carries the configuration information in the notification message and sends the notification message to the sending equipment, and the sending equipment determines the frequency domain resource location information according to the received configuration information. The configuration information may include a center frequency point and a bandwidth, a start position and an end position in a frequency domain, and a period and an offset in the frequency domain. In addition, the configuration information may also be that the sending device selects one of the frequency domain resource locations from at least one possible frequency domain resource location pre-agreed by the sending device and the receiving device to indicate to the receiving device, or that the sending device configures more than one possible frequency domain resource locations through a high-level signaling first, and then indicates one of the possible frequency domain resource locations to the receiving device through a dynamic signaling. The configuration information may be sent to a group of receiving devices, or may be sent to all receiving devices served by the sending device. For the specific indication manner of the frequency domain resource location, the embodiment is not limited herein

For example, in the transmission scheme shown in fig. 14, the receiving device may determine the specific frequency domain resource location information and time domain resource location information of the information block in the above-described manner.

Step 202: the receiving device receives the information block on the first frequency domain resource on the first time domain resource and the first frequency domain resource on the second time domain resource.

In this embodiment, the receiving device receives the information block on the first frequency domain resource on the first time domain resource and the first frequency domain resource on the second time domain resource, that is, the receiving device can receive the complete information on the narrower frequency domain resource, for example, the frequency domain resource occupied by one information block, by increasing the continuous receiving time.

Step 203: the receiving device demodulates the information block.

In this embodiment, after determining the time domain resource location and the frequency domain resource location of an information block in information to be received, the receiving device identifies the sequence number of each information block.

Specifically, the transmitting device may transmit different information blocks after scrambling with different scrambling codes or masks. Wherein, the generation of the scrambling code or the mask is related to the sequence number of the information block, and the related relationship can be predetermined by the standard. In addition, the generation of the scrambling code or the mask may also be related to the transmission sample number where the information block is located, referring to fig. 14, that is, the mapping order of the information blocks in different transmission samples may be different. Accordingly, the receiving device may determine the sequence number of the information block by detecting the scrambling code or the mask of the information block.

In addition, when receiving a broadcast signal, the receiving device may confirm a System Frame Number (SFN). One implementation method is that after the serial number of the information block is confirmed, the system frame number is confirmed, all or part of the information of the system frame number is indicated by the information block, or different mapping sequences of the information block or the serial number of the information block are related to the system frame number, that is, after the sequence of the information block or the serial number of the information block is confirmed, all or part of the information of the system frame number can be uniquely confirmed, wherein the related relationship can be agreed by the standard in advance. For example, the broadcast information is divided into 4 information blocks and transmitted by the method shown in fig. 14, the transmission period is 40ms and is transmitted every 10ms, the receiving end can determine the lowest two bits of the SFN according to the received signal being the signal in the 10 th ms, and the rest SFN bits are indicated in the information blocks. In yet another implementation, the receiving device may identify the SFN based on the scrambling code or mask of the information block, i.e. the generation of the scrambling code or mask is related to the SFN. Another implementation method is that the receiving device first confirms the SFN serial number, and may indicate the SFN through the dedicated indication information, and then the receiving device confirms the mapping order of the information blocks in the transmission samples, i.e. the serial numbers of the information blocks, according to the SFN serial number. The time frequency resource location where the dedicated indication information is located is predetermined by the sending device and the receiving device, for example, specified by a communication standard.

Finally, after identifying the serial number of each information block, the receiving device detects or demodulates the information block to obtain all or part of the transmitted information.

For example, in the transmission scheme shown in fig. 14, the receiving device may determine the sequence numbers of 4 information blocks in the above-described manner, and detect or demodulate the information blocks according to the determined sequence numbers to obtain all or part of the transmission information.

Fig. 26 is a flowchart illustrating a second embodiment of an information receiving method according to the present invention. The embodiment of the invention provides an information receiving method, which can be executed by any device for executing the information receiving method, and the device can be realized by software and/or hardware. In this embodiment, the apparatus may be integrated in a receiving device, and the receiving device may be, for example, a terminal device. As shown in fig. 26, the method of this embodiment may include:

step 301: the receiving device determines time-frequency resource location information of information blocks in the received signal.

In this embodiment, before demodulating, decoding, and transmitting information sent by a transmitting device, a receiving device needs to determine a specific number of information blocks in a received signal, and a time-frequency resource position, i.e., a time-frequency resource position and a frequency-frequency resource position, of the information blocks in the received signal; the information block is obtained by dividing information to be transmitted by the transmitting device before transmission.

The method for the receiving device to determine the time domain resource location of each information block includes the following steps: the first method comprises the following steps: the receiving device and the sending device may agree on the time domain resource location in advance, and in practical application, may agree on the sending period and the time domain resource location occupied by the information block in each period. For example: if the sending information is PBCH, the receiving device may determine the time domain resource location of the information block of the signal to be received according to the time domain resource location where the detected synchronization signal is located and the relative time domain location of the synchronization signal and the broadcast signal that is agreed in advance.

Step 302: the receiving device receives the information block on a first frequency domain resource on a first time domain resource and a second frequency domain resource on the first time domain resource.

In this embodiment, the receiving device may obtain the complete information in the first time domain resource through one-time reception on the wider frequency domain resource by receiving the information block on the first frequency domain resource on the first time domain resource and the second frequency domain resource on the first time domain resource, and receive the complete information.

Step 303: the receiving device demodulates the information block.

In addition, when receiving a broadcast signal, the receiving apparatus can confirm the SFN. One implementation method is that after the serial number of the information block is confirmed, the system frame number is confirmed, all or part of the information of the system frame number is indicated by the information block, or different mapping sequences of the information block or the serial number of the information block are related to the system frame number, that is, after the sequence of the information block or the serial number of the information block is confirmed, all or part of the information of the system frame number can be uniquely confirmed, wherein the related relationship can be agreed by the standard in advance. For example, the broadcast information is divided into 4 information blocks and transmitted by the method shown in fig. 14, the transmission period is 40ms and is transmitted every 10ms, the receiving end can determine the lowest two bits of the SFN according to the received signal being the signal in the 10 th ms, and the rest SFN bits are indicated in the information blocks. In yet another implementation, the receiving device may identify the SFN based on the scrambling code or mask of the information block, i.e. the generation of the scrambling code or mask is related to the SFN. Another implementation method is that the receiving device first confirms the SFN serial number, and may indicate the SFN through the dedicated indication information, and then the receiving device confirms the mapping order of the information blocks in the transmission samples, i.e. the serial numbers of the information blocks, according to the SFN serial number. The time frequency resource location where the dedicated indication information is located is predetermined by the sending device and the receiving device, for example, specified by a communication standard.

The program may be stored in a computer-readable storage medium. When executed, the program performs steps comprising the method embodiments described above; and the aforementioned storage medium includes: various media that can store program codes, such as ROM, RAM, magnetic or optical disks.
