In addition, the network device 102 may additionally include a transmitter chain and a receiver chain, and those of ordinary skill in the art may understand that they may include multiple components related to signal transmission and reception (such as processors, modulators, multiplexers, etc.) , demodulator, demultiplexer or antenna, etc.).

Network device 102 may communicate with a plurality of end devices (eg, end device 116 and end device 122 ). However, it is understood that network device 102 may communicate with any number of end devices similar to end devices 116 or 122 . Terminal devices 116 and 122 may be, for example, cellular phones, smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable devices for communicating over wireless communication system 100. equipment.

As shown in FIG. 1 , terminal device 116 communicates with antennas 112 and 114 , which transmit information to terminal device 116 via forward link 118 and receive information from terminal device 116 via reverse link 120 . Additionally, terminal device 122 is in communication with antennas 104 and 106 , wherein antennas 104 and 106 transmit information to terminal device 122 via forward link 124 and receive information from terminal device 122 via reverse link 126 .

For example, in a Frequency Division Duplex (FDD, Frequency Division Duplex) system, for example, the forward link 118 can utilize a frequency band different from that used by the reverse link 120, and the forward link 124 can utilize the same frequency band as the reverse link. 126 different frequency bands used.

For another example, in a time division duplex (TDD, Time Division Duplex) system and a full duplex (Full Duplex) system, the forward link 118 and the reverse link 120 can use a common frequency band, and the forward link 124 and the reverse Link 126 may use a common frequency band.

Each antenna (or group of antennas) and/or area designed for communication is referred to as a sector of network device 102 . For example, antenna groups may be designed to communicate with terminal devices in sectors of the coverage area of network device 102 . During communication between network device 102 and terminal devices 116 and 122 over forward links 118 and 124, respectively, the transmit antennas of network device 102 may utilize beamforming to improve the signal-to-noise ratio of forward links 118 and 124. Furthermore, when the network device 102 uses beamforming to transmit signals to randomly dispersed terminal devices 116 and 122 in the relevant coverage area, compared to the way in which the network device transmits signals to all its terminal devices through a single antenna, the Mobile devices experience less interference.

At a given time, the network device 102, the terminal device 116, or the terminal device 122 may be a wireless communication sending device and/or a wireless communication receiving device. When transmitting data, the wireless communication transmitting device may encode the data for transmission. Specifically, a wireless communication sending device may obtain (eg, generate, receive from another communication device, or store in memory, etc.) a certain number of data bits to be sent to a wireless communication receiving device through a channel. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

In addition, the communication system 100 may be a public land mobile network (English full name may be: Public LandMobile Network, English abbreviation may be: PLMN) network or a D2D network or an M2M network or other networks. FIG. 1 is only a simplified schematic diagram of an example. It may also include other network devices, which are not shown in FIG. 1 .

It should be noted that, in this embodiment of the present invention, the sending device may be the above-mentioned network device 102 or a terminal device (for example, terminal device 116 or terminal device 122), and correspondingly, the receiving device may be the above-mentioned terminal device ( For example, the terminal device 116 or the terminal device 122) may also be the network device 102, which is not particularly limited in this embodiment of the present invention.

In an embodiment of the present invention, at least two services may be transmitted in the communication system, wherein, in the communication system, a reserved time-frequency is configured for one of the at least two services (for example, the second service) resource.

In the embodiment of the present invention, "the time-frequency resource reserved for the second service" can be understood as that the communication system or the communication protocol stipulates that the time-frequency resource reserved for the second service is only used to transmit the data of the second service; In other words, the communication system or the communication protocol stipulates that the time-frequency resources reserved for the second service are prohibited from being used to transmit data of services other than the second service (eg, the first service).

Alternatively, "the time-frequency resources reserved for the second service" can also be understood as that the communication system or communication protocol stipulates that the time-frequency resources reserved for the second service are preferentially used to transmit the data of the second service, for example, when there is no need When transmitting data of the second service, the time-frequency resources reserved for the second service can be used to transmit data of other services (for example, the first service); The reserved time-frequency resources need to first ensure the transmission of the data of the second service. On the premise that the data transmission of the second service is satisfied, the remaining time-frequency resources in the time-frequency resources reserved for the second service can be used for transmission Data of other services (for example, the first service).

Alternatively, "time-frequency resources reserved for the second service" can also be understood as candidate time-frequency resources for transmitting data of the second service, and the data that can be transmitted through the candidate time-frequency resources may include data of the first service and The data of the second service, and the transmission priority of the second service is higher than the transmission priority of the first service, or in other words, when the data of the first service and the second service need to be transmitted through candidate time-frequency resources within the same period of time, When the data of the second service is transmitted, the data of the second service transmitted by the candidate time-frequency resource is given priority. After receiving the data of the service, the data of the first service can be transmitted through the candidate time-frequency resource; or, when a part of the candidate time-frequency resource can meet the data transmission of the second service, the remaining part of the candidate time-frequency resource can be used to transmit the data of the second service Data of the first business.

As an example but not a limitation, the first service may be an enhanced mobile Internet (eMBB, enhancedMobile BroadBand) service. The second service may be an Ultra Reliable & Low Latency Communication (URLLC, Ultra Reliable & Low Latency Communication) service.

Specifically, the International Telecommunications Union Radio Communications Committee (ITU-R, International Telecommunications Union-Radio Communications Sector) has defined three types of application scenarios for 5G in the future, namely enhanced mobile Internet services (eMBB, Enhanced Mobile Broadband), mass connection Internet of Things business (mMTC, Massive Machine Type Communication) and ultra-high reliability and ultra-low latency business (URLLC, Ultra Reliable&Low Latency Communication), and from 8 dimensions of throughput, delay, connection density and spectral efficiency improvement Defines the capability requirements for 5G networks. Among them, the eMBB service mainly requires high speed, wide coverage, transmission delay and mobility. The main requirements of the URLLC service are extremely high reliability, low mobility, and transmission delay. Generally, the wireless air interface is required to achieve 99.999% transmission reliability within 1 millisecond (ms).

For the URLLC service, in order to ensure the delay requirement, the service is required to be sent immediately after arriving at the base station, and certain time-frequency resources are required for sending URLLC data. In the 5G system, different services can be multiplexed in one carrier, and the multiplexing method can be frequency division multiplexing (FDM, Frequency Division Multiplexing) or time division multiplexing (TDM, Time Division Multiplexing). In order to ensure the service requirements of URLLC, in the current research and standard discussion, it tends to reserve a section of frequency band resources for URLLC (that is, an example of time-frequency resources reserved for the second service), so as to ensure that when the service of URLLC arrives, there will always be Frequency resources are used for transmission, that is, as shown in Figure 2, URLLC and other services (such as eMBB services) are frequency division multiplexed on the same carrier.

In the embodiment of the present invention, the URLLC service and the eMBB service are frequency division multiplexed, and the eMBB service can temporarily use the resources reserved for the URLLC service. On the resources reserved for the URLLC service, the URLLC service (specifically, the data) arrives, if the eMBB service is being transmitted on the resources reserved by the URLLC service, the eMBB service being transmitted is punched, and the URLLC service is transmitted at the punched position.

Hereinafter, for ease of understanding and description, the eMBB service is taken as the first service and the URLLC service is taken as the second service, and the method for transmitting data according to the embodiment of the present invention is described in detail.

Fig. 3 is a schematic interaction diagram of a method 300 for transmitting data according to an embodiment of the present invention.

Specifically, at S210, the sending device (or encoding end) may use encoding mode #A (that is, an example of the first encoding mode) to encode the eMBB service data that needs to be sent to the receiving device (or decoding end) (That is, an example of the first data of the first service, hereinafter, for ease of understanding and distinction, is referred to as: data #A) and coded.

As an example but not a limitation, in this embodiment of the present invention, the encoding manner #A may be the following encoding manner.

Here, the object encoded by the encoding mode #A may be the data processed by information source encoding. That is, this coding scheme #A may be a channel coding scheme.

Specifically, source coding is a transformation of source symbols for the purpose of improving communication effectiveness, or in other words, a transformation of source symbols to reduce or eliminate source margins. Specifically, it is to find a method according to the statistical characteristics of the source output symbol sequence, and transform the source output symbol sequence into the shortest codeword sequence, so that the average amount of information carried by each symbol of the latter is the largest, and at the same time It is guaranteed to restore the original symbol sequence without distortion.

One of the functions of source coding is to try to reduce the number of symbols and reduce the rate of symbols, which is commonly referred to as data compression; the second function is to convert the analog signal of the source into a digital signal to realize the digital transmission of the analog signal.

Channel coding is a theory and method for improving channel reliability realized by channel encoder and decoder. Channel coding can be roughly divided into two categories:

①The channel coding theorem solves the existence problem of ideal encoder and decoder theoretically, that is, solves the possibility of the maximum information rate that the channel can transmit and the transmission problem when it exceeds this maximum value.

② Constructive coding methods and the performance limits that these methods can achieve.

During the transmission of digital signals, due to various reasons, bit errors occur in the transmitted data stream, which causes phenomena such as image jumping, discontinuity, and mosaics at the receiving end. Therefore, through the link of channel coding, the digital stream is processed accordingly, so that the system has certain error correction capabilities and anti-interference capabilities, which can greatly avoid the occurrence of bit errors in the transmission of code streams. Error processing techniques include error correction, interleaving, and linear interpolation.

Moreover, data transmission efficiency can be improved through channel coding, and the task of channel coding is to reduce the bit error rate.

The essence of channel coding is to increase the reliability of communication. However, channel coding will reduce the transmission of useful information data. The process of channel coding is to insert some symbols into the source data stream, so as to achieve the purpose of error judgment and error correction at the receiving end. This is what we often call overhead. . In a channel with a fixed bandwidth, the total transmission code rate is also fixed. Since channel coding increases the amount of data, the result can only be at the cost of reducing the code rate for transmitting useful information. Dividing the number of useful bits by the total number of bits is equal to the coding efficiency. Different coding methods have different coding efficiencies.

As an example but not a limitation, in the embodiment of the present invention, the encoding method #A can be encoded in the following manner:

For example, the sending device may use an existing channel coding method (hereinafter, for ease of understanding, denoted as: coding method #A-1) to encode data (for example, data #A after information source coding processing), so as to Generate a plurality of original code blocks (that is, an example of MN original first code blocks, hereinafter referred to as: original code block #A ₁ -original code block #A _MN ) for ease of understanding and distinction.

Here, the M-N may be an integer greater than or equal to 2, that is, the number of original code blocks may be at least two.

As an example but not a limitation, the coding method #A-1 may be, for example, a block code coding method, a convolutional code coding method, a polar code coding method, a turbo code coding method, and the like.

Moreover, the process of the sending device encoding the data #A based on the encoding mode #A-1 may be similar to that of the prior art, and here, in order to avoid redundant description, its detailed description is omitted.

Afterwards, the sending device can further process the original code block #A ₁ ~ original code block #A _MN in the encoding mode #A-2, so as to obtain multiple redundant code blocks (that is, N redundant first code blocks One example, below, for the convenience of understanding and distinction, is recorded as: redundant code block #A _M-N+1 to redundant code block #A _M ).

Here, the N may be an integer greater than or equal to 1, that is, the number of redundant code blocks may be at least one.

As an example but not a limitation, in this embodiment of the present invention, the original code block #A ₁ ~ original code block #A _MN can be used as input parameters, and, for example, a prescribed weight can be assigned to each input parameter, and a preset The established algorithm performs operation processing (for example, addition operation or subtraction operation, etc.) on each input parameter, so as to output redundant code block #A _M-N+1 ˜redundant code block #A _M .

In addition, in the embodiment of the present invention, the redundant code block may include the component of each original code block in the original code block #A ₁ ~ original code block #A _MN , or in other words, the redundant code block may be based on the original code block #A ₁ ~ original code block #A _MN generated, thus, when part (for example, one) code block in the original code block is missing during transmission (for example, being punctured by the sending device and causing the missing), The missing code block can be recovered based on the original code block that is not missing and the redundant code block, so that the receiving device can accurately and reliably recover the data #A that the sending device needs to send.

It should be noted that, in the embodiment of the present invention, the number of redundant code blocks may be one or more, which is not particularly limited in the embodiment of the present invention. When there is one redundant code block, the one redundant code block It may include the components of each original code block in the original code block #A ₁ ~ the original code block #A _MN (or, the data generated after the components of each original code block are processed by a specified algorithm); when the redundant code When there are multiple blocks, the multiple redundant code blocks may include the components of each original code block in the original code block #A ₁ ~ original code block #A _MN (or, the components of each original code block are specified data generated after algorithm processing), for example, each redundant code block can include the components of each original code block in the original code block #A ₁ ~ original code block #A _MN , or a redundant code block can Including the components of a part of the original code blocks in the original code block #A ₁ ~ the original code block #A _MN (or, the data generated after the components of this part of the original code block are processed by the specified algorithm), another redundant code block can be It includes the components of another part of the original code blocks among the original code blocks #A ₁ -the original code blocks #A _MN (or the data generated after the components of this part of the original code blocks are processed by a prescribed algorithm).

As an example but not a limitation, the encoding mode #A (or in other words, the encoding mode #A-2) may be an outer code (outercode) encoding mode. Moreover, the specific process and method of the outer code encoding method may be similar to the prior art, and here, in order to avoid redundant description, its detailed description is omitted.

It should be understood that the specific process of the encoding manner #A listed above is only for illustration, and this embodiment of the present invention is not limited thereto.

As an example and not a limitation, in the embodiment of the present invention, the coding method #A may be a joint coding method (that is, an example of the first coding method), that is, a joint coding method is used for certain data (hereinafter, for convenience Understanding and distinction, recorded as: Data #β) can produce multiple coding units (or code blocks) after encoding, and the data #β can be decoded without passing through all the coding units in the multiple coding units. In other words, the data #β can be decoded by only a part of the coding units in the plurality of coding units.

In addition, as an encoding method different from the joint encoding method, in the embodiment of the present invention, an individual encoding method (that is, an example of the second encoding method) can be cited, that is, a certain data using the individual encoding method (hereinafter, for It is easy to understand and distinguish, and it is recorded as: data #γ) can produce multiple coding units (or code blocks) after encoding, and only through all the coding units in the multiple coding units can the data #γ be decoded , or in other words, the data #γ cannot be decoded by only a part of the coding units in the plurality of coding units.

For example, in this embodiment of the present invention, the encoding mode #A can be encoded as follows:

The sending device can first divide the data into multiple original code blocks (that is, an example of MN original first code blocks, denoted as: original code block #B ₁ ~ original code block #B _MN ), here, the MN can be An integer greater than or equal to 1, that is, the number of original code blocks may be at least one.

Afterwards, the sending device can further process the original code block #B ₁ ~ original code block #B _MN in the encoding mode #A-2, so as to obtain multiple redundant code blocks (that is, N redundant first code blocks For example, it is recorded as: redundant code block #B _M-N+1 to redundant code block #B _M ). Here, the N may be an integer greater than or equal to 1, that is, the number of redundant code blocks may be at least one.

And, as an example but not a limitation, in the embodiment of the present invention, the original code block #B ₁ to original code block #B _MN can be used as input parameters, and, for example, a prescribed weight can be assigned to each input parameter, and A preset algorithm is used to perform arithmetic processing (for example, addition or subtraction) on each input parameter, so as to output redundant code blocks #B _M-N+1 to #B _M .

Afterwards, as an example and not a limitation, the sending device may use the existing channel coding method (coding method #A-1) to perform encoding processing on the M first code blocks respectively, and generate M first code blocks (denoted as code block #A ₁ to code block #A _M ), the coding method #A-1 may be, for example, a block code coding method, a convolutional code coding method, a polar code coding method or a turbo code coding method, etc.

Moreover, the process of encoding the M first code blocks by the sending device based on the encoding mode #A-1 may be similar to that in the prior art, and detailed description thereof is omitted here to avoid redundant description.

For another example, in the embodiment of the present invention, for example, the communication system or the communication protocol may stipulate that the first code block of the first service transmitted on the time-frequency resources reserved for the second service will not be punctured. In this case , the sending device can also only use the original code block #A ₂ ~ original code block #A _MN as input parameters, and, for example, can assign a prescribed weight to each input parameter, and use a preset algorithm to perform Operation processing (for example, addition operation, subtraction operation, etc.), so as to output redundant code block #A _M-N+1 ˜redundant code block #A _M . That is, the original code block #A ₁ may not participate in the outer code encoding. In this case, the redundant code block may not include the components of the original code block #A ₁ , or in other words, the redundant code block may be based on the original code block #A ₂ ～Original code block #A generated by _MN .

Thus, the M code blocks (that is, an example of M first code blocks) generated after encoding the data #A via the encoding method #A are hereinafter referred to as: code block #A ₁ ~code Block #A _M ) includes original code block #A ₁ -original code block #A _MN and redundant code block #A _M-N+1 -redundant code block #A _M .

Thereafter, the sending device may determine the code block used to carry the code block from the time-frequency resources reserved for the URLLC service (that is, an example of the second service) (hereinafter, for ease of understanding and distinction, denoted as reserved resources). Time-frequency resources of #A ₁ -code block #A _M (hereinafter, for ease of understanding and distinction, referred to as: time-frequency resource #A ₁ -time-frequency resource #A _M ). And the code block #A ₁ ~code block #A _M is carried on the time-frequency resource #A ₁ ~time-frequency resource #A _M , wherein, the code block #A ₁ ~code block #A _M and the time-frequency resource # A ₁ to time-frequency resource #A _M can be in one-to-one correspondence, that is, each code block can be borne on the corresponding time-frequency resource.

It should be noted that, in this embodiment of the present invention, the time-frequency resource #A ₁ to the time-frequency resource #A _M may be all resources in the reserved resources, or the time-frequency resource #A ₁ to the time-frequency resource # A _M may also be a part of reserved resources, which is not particularly limited in this embodiment of the present invention.

In S220, the sending device may send some or all of the code blocks in the code block #A ₁ to the code block #A _M through some or all of the time-frequency resources in the time-frequency resource #A ₁ to the time-frequency resource #A _M.

Specifically, in the embodiment of the present invention, during the process of transmitting the code block #A ₁ to the code block #A _M , there may be situations where it is necessary to transmit the data of the URLLC service (that is, an example of the data of the second service), Since the time-frequency resource #A ₁ to the time-frequency resource #A _M belong to the time-frequency resource reserved for the URLLC service, there may be some of the time-frequency resource #A ₁ to the time-frequency resource #A _M (for example, a ) The time-frequency resource needs to be used to transmit the data of the URLLC service. Therefore, the transmission of code block #A ₁ to code block #A _M may include the following situations:

Case 1

When there is no need to transmit the data of the URLLC service, the sending device can use all the time-frequency resources (that is, an example of the first time-frequency resource) in the time-frequency resource #A ₁ to the time-frequency resource #A _M to send the code block #A ₁ ~ All code blocks in code block #A _M.

Case 2

When the data of the URLLC service needs to be transmitted, and the time-frequency resources other than the time-frequency resource #A ₁ to the time-frequency resource #A _M in the reserved resources (hereinafter, for the sake of understanding and distinction, referred to as: remaining time-frequency resources) can be When the transmission requirements of the URLLC service are met, the sending device can use all the time-frequency resources (that is, an example of the first time-frequency resource) in the time-frequency resource #A ₁ to the time-frequency resource #A _M to send the code block #A ₁ to All the code blocks in the code block #A _M , and the sending device can use some or all of the time-frequency resources in the remaining time-frequency resources (that is, an example of the third time-frequency resource) to send URLLC service data, wherein The process of the device sending the data of the URLLC service may be similar to that of the prior art, and here, to avoid redundant description, its detailed description is omitted.

Case 3

When the data of the URLLC service needs to be transmitted, and the remaining time-frequency resources in the reserved resources cannot meet the transmission requirements of the URLLC service, the sending device can use the above-mentioned remaining time-frequency resources and time-frequency resources #A ₁ to time-frequency resources #A _M Part of the time-frequency resources in the URLLC service data, that is, the sending device can puncture part (for example, 1) of the code blocks in the code block #A ₁ to code block #A _M , and the data of the URLLC service It is carried in the time-frequency resource corresponding to the punctured code block. Therefore, in this case, the sending device uses part of the time-frequency resources (that is, another example of the first time-frequency resource) among the time-frequency resources #A ₁ to time-frequency resources #A _M to transmit the code block #A ₁ to the code block Partial code blocks in #A _M. In addition, the sending device may use the remaining time-frequency resources and some time-frequency resources (that is, another example of the third time-frequency resource) among time-frequency resources #A ₁ to time-frequency resources #A _M to send URLLC service data, where The process by which the generating device sends the data of the URLLC service may be similar to that of the prior art, and here, to avoid redundant description, its detailed description is omitted.

It should be noted that, in the above case, the code blocks punctured by the sending device may belong to the original code blocks in code blocks #A ₁ to code blocks #A _M , or may belong to code blocks #A ₁ to code blocks #A The redundant code blocks in _M are not particularly limited in this embodiment of the present invention.

In addition, the number of code blocks punctured by the transmitting device listed above is only an example, and the embodiment of the present invention is not particularly limited, as long as the receiving device can accurately recover the required code blocks of the generating device based on the unpunctured code blocks. The data sent can be.

Next, the process of obtaining data #A by the receiving device will be described in detail.

As described above, the transmitting device transmits the code block #A ₁ to the code block # through some or all of the time-frequency resources (that is, an example of the first time-frequency resource) in the time-frequency resource #A ₁ to the time-frequency resource #A _M After part or all of the code blocks in A _M , at S220, the receiving device may detect the above-mentioned reserved resource, and receive the code block of the eMBB service carried in the reserved resource, that is, the above-mentioned code block #A ₁ ~ some or all of the code blocks in the code block #A _M.

It should be noted that, in the embodiment of the present invention, the downlink control information (DCI, Downlink Control Information) can be used between the sending device and the receiving device to determine: the code block of the eMBB service carried in the reserved resource, or in other words, A location of a time-frequency resource (that is, an example of the first time-frequency resource) of a code block used to carry an eMBB service.

In addition, when encoding the eMBB service data using the above-mentioned outer code encoding method (that is, the above-mentioned encoding method #A), the receiving device also needs to distinguish between the original code block and the redundant code block of the transmitted eMBB service code block .

As an example but not a limitation, for example, the sending device may also send indication information (that is, an example of the third indication information) used to indicate the location of the time-frequency resource used to bear the redundant code block to the receiving device.

Or, for example, the sending device may also send indication information (that is, another example of the third indication information) for indicating the position of the time-frequency resource used to bear the original code block to the receiving device.

Therefore, the receiving device can identify the redundant code block and the original code block from the code block #A ₁ to code block #A _M according to the third indication information.

By making the sending device notify the receiving device of the positions of the N redundant first code blocks in the first time-frequency resource, the receiving device can easily determine the original first code block and the redundant The remaining first code blocks can further enable the receiving device to easily restore the first data based on the original first code blocks and the redundant first code blocks.

It should be understood that the method and process for the receiving device to distinguish the original code block and the redundant code block of the code block of the eMBB service listed above are only illustrative, and the embodiments of the present invention are not limited thereto. For example, the communication system Or the communication protocol can also pre-determine the arrangement or positional relationship of the original code block and the redundant code block, so that the sending device can transmit the original code block and the redundant code block according to the above-mentioned regulations, and the receiving device can identify the original code block according to the above-mentioned regulations and redundant code blocks.

In S230, the receiving device may base on the original code blocks and redundant code blocks in the received code blocks of the eMBB service (that is, some or all of the above-mentioned code blocks #A ₁ to code blocks #A _M ) , perform decoding processing on the code block #A ₁ -code block #A _M according to the encoding method #A (for example, the encoding method #A-1 and/or the encoding method #A2), so as to obtain the above-mentioned data #A.

As an example but not a limitation, for example, the receiving device may first try to decode the original code blocks in the code blocks of the received eMBB service by using the encoding mode #A-1.

If it can be decoded normally, the receiving device can determine that the original code blocks in the code block #A ₁ to code block #A _M are not missing (for example, not punctured), so the decoded data can be regarded as the above data #A.

If it cannot be decoded normally, the receiving device may determine that some code blocks in the original code blocks in the code block #A ₁ to code block #A _M are missing (for example, punctured). In this case, the receiving device may be based on Coding method #A-2, based on the original code block and redundant code block in the code block of the eMBB service received, restore the above original code block #A ₁ ~ original code block #A _MN , and then based on the coding method# A-1 performs decoding processing on original code block #A ₁ to original code block #A _MN to obtain the above-mentioned data #A.

For another example, the receiving device can also directly restore the original code block #A 1 to the original code block based on the received original code block and redundant code block in the code block of the eMBB service according to the encoding method #A _-2 #A _MN , and then decode the original code block #A ₁ -original code block #A _MN based on the encoding method #A-1, so as to obtain the above data #A.

It should be noted that the receiving device restores the original code block #A ₁ to the original code block #A _MN according to the encoding method #A-2 and the original code block and redundant code block in the received code block of the eMBB service The process can be that the sending device generates the original code block and the redundant code block in the code blocks of the received eMBB service according to the encoding method #A-2 and the original code block #A ₁ ~ original code block #A _MN to recover The reverse process of generating redundant code block #A _M-N+1 ~ redundant code block #A _M , here, in order to avoid redundant description, its detailed description is omitted.

As an example but not a limitation, in this embodiment of the present invention, the sending device and the receiving device are sending eMBB services (that is, an example of the first service) using time-frequency resources reserved for URLLC services (that is, an example of the second service) For the data, the encoding method used (for example, the above-mentioned encoding method #A) may be specified by the communication system or communication protocol.

That is, when the system fixes the frequency band division between the eMBB service and the URLLC service, the sending device and the receiving device can clearly know the resources reserved for the URLLC service, so that the sending device and the receiving device can determine Whether the encoding method used on resources reserved for URLLC services is different from the encoding method adopted on resources allocated to eMBB services; furthermore, it can also be pre-defined by the system or indicated by system messages in the resources reserved for URLLC services The specific encoding method used on the resource.

Alternatively, in the embodiment of the present invention, the sending device and the receiving device may also determine (for example, through signaling) the encoding mode used when sending eMBB service data using the time-frequency resource reserved for the URLLC service.

For example, one of the sending device and the receiving device (for example, a network device in the sending device and the receiving device) may send a message to the other of the sending device and the receiving device (for example, a terminal device in the sending device and the receiving device) for Indication information indicating the encoding mode used when sending eMBB service data using the time-frequency resources reserved for the URLLC service (that is, an example of the first indication information or the second indication information).

Alternatively, one of the sending device and the receiving device (for example, a network device in the sending device and the receiving device) may send a message to the other of the sending device and the receiving device (for example, a terminal device in the sending device and the receiving device) for _Indication information (that is, the _first indication information or the second indication An example of information). It should be noted that in this case, the first time-frequency resource may be determined through an indication of the DCI.

That is, when the frequency band division of the eMBB service and the URLLC service is dynamically changed, in each subframe, the network device can use, for example, downlink control information (DCI, Downlink Control Information) to instruct the terminal device to use the downlink control information DCI to schedule The coding method used for data transmission. For example, for eMBB service, the system defaults to a channel coding method, such as coding method #A-1. In the downlink control information DCI, notify whether the coding method used for the data transmission scheduled by the downlink control information DCI is Different from the coding method #A-1, further, the coding method that is different from the system default channel coding method may be indicated through downlink control information DCI or a system message.

By determining that the sending device and the receiving device need to transmit the data of the first service on the time-frequency resource reserved for the second service based on the first coding method, the sending device and the receiving device can use the same coding method on the first time-frequency resource The data of the first service is uploaded, so that the reliability and accuracy of the transmission can be further improved.

According to the data transmission method of the embodiment of the present invention, since the first time-frequency resource belongs to the time-frequency resource reserved for the second service, when the data of the second service needs to be transmitted, the M-N original first code blocks may be Part of the code blocks in the M first code blocks formed with the N redundant first code blocks are punctured, so that the receiving end cannot receive one or more code blocks in the M first code blocks. , by using the first encoding method to further perform encoding processing on the basis of the M-N original first code blocks generated according to the first data, so as to generate N redundant first code blocks, it is possible for the receiving device to receive In the case of one or more code blocks in the M first code blocks, the first data can still be obtained through a redundancy algorithm, so that the reliability and accuracy of transmission can be improved.

In S240, the sending device may use the coding method #B (that is, an example of the second coding method) to encode the data of the eMBB service that needs to be sent to the receiving device (that is, an example of the second data of the first service, hereinafter, for the sake of understanding And distinguish, record as: data #B) encode.

Here, the object encoded by the encoding method #B may be the data processed by information source encoding. That is, this coding method #B may be a channel coding method.

For example, the sending device may encode data (eg, data #B after information source encoding processing) by using encoding mode #B to generate multiple original code blocks (ie, an example of the second code block).

As an example but not a limitation, the coding method #B may be, for example, a block code coding method, a convolutional code coding method, a polar code coding method, a turbo code coding method, and the like.

Moreover, the process of the sending device encoding the data #B based on the encoding method #B may be similar to that of the prior art, and here, in order to avoid redundant description, its detailed description is omitted.

In addition, in the embodiment of the present invention, the encoding method #B may be the same as or different from the above encoding method #A-1, which is not particularly limited in the embodiment of the present invention.

Thereafter, the sending device determines the time-frequency resource (that is, an example of the second time-frequency resource) used to bear the second code block from the time-frequency resources allocated for the eMBB service (that is, an example of the first service) . That is, the second time-frequency resource belongs to the time-frequency resource that can be used to transmit the eMBB service specified by the communication system or the communication protocol, or in other words, the second time-frequency resource does not belong to the URLLC service (that is, an example of the second service ) reserved time-frequency resources.

At S250, the sending device sends the second code block to the receiving device through the second time-frequency resource.

Correspondingly, at S250, the receiving device may receive the second code block through the second time-frequency resource, and at S260, the receiving device may decode the second code block based on the coding method #B, and then obtain data #B.

It should be noted that the transmission process of data #B described in the above S240-S260 may be similar to the prior art, and here, in order to avoid redundant description, its detailed description is omitted.

That is, in the embodiment of the present invention, the encoding method #B is different from the encoding method #A, or in other words, for the eMBB service, the encoding method used in the transmission process on the time-frequency resources reserved for the URLLC service is different from that used in the The encoding methods used in the transmission process on the time-frequency resources other than the time-frequency resources reserved for the URLLC service are different.

Therefore, by using coding methods with different error correction capabilities on different time-frequency resources, an appropriate coding method can be selected based on communication conditions on different time-frequency resources, thereby improving transmission accuracy and reliability.

It should be understood that the encoding method #A listed above is only an example of the first encoding method in the embodiment of the present invention, and the first encoding method in the embodiment of the present invention is not particularly limited, and the first encoding method in the embodiment of the present invention may also be For other channel coding methods in the prior art, only the first coding method and the second coding method in the embodiment of the present invention are different.

For example, in another embodiment of the present invention, the encoding method #A can also be the following encoding method, and the sending device (or encoding device) can encode data #A through an encoder (for example, using a fountain code encoding method) , so as to generate multiple (that is, M, the value of M can be infinitely large) coding units, or in other words, generate an infinitely long codeword sequence, wherein, the M coding units can be divided into a plurality of coding unit combinations , where any one coding unit combination may include some or all of the M coding unit combinations, and the intersection between any two coding unit combinations in the multiple coding unit combinations is an empty set, or in other words, the multiple coding unit combinations There is at least one different coding unit between any two coding unit combinations in the coding unit combinations. Also, data #A can be obtained by decoding any combination of coding units.

Afterwards, the sending device may determine from the time-frequency resources (or candidate time-frequency resources) reserved for the URLLC service (that is, an example of the second service) to carry any one of the combinations of the above-mentioned coding units. The time-frequency resource of the unit combination (hereinafter, for ease of understanding and distinction, denoted as coding unit combination #A, that is, the coding unit combination #A includes some or all of the M coding units), and sends the coding unit Combination #A. In other words, the sending device may send part of codewords (or sub-codeword sequences) in the infinitely long codeword sequence to the receiving device until receiving a confirmation message fed back by the receiving device.

In addition, optionally, the method also includes:

The sending device uses the second encoding method to send the third data of the first service through the third time-frequency resource, where the third time-frequency resource belongs to the time-frequency resource reserved for the second service.

Specifically, in the embodiment of the present invention, when the sending device and the receiving device can determine that there is no need to transmit the URLLC service, the sending device can also use encoding mode B to send eMBB service data on the time-frequency resources reserved for the URLLC service.

Correspondingly, in this embodiment of the present invention, before the sending device and the receiving device transmit the data of the eMBB service on the time-frequency resources reserved for the URLLC service using the encoding mode #A, the sending device and the receiving device may first determine whether The data of the URLLC service is transmitted on the time-frequency resource reserved for the URLLC service.

If it is determined to be yes, the sending device and the receiving device can use the encoding mode #A to transmit eMBB service data on the time-frequency resource reserved for the URLLC service.

If the determination is no, the sending device and the receiving device may transmit eMBB service data on the time-frequency resources reserved for the URLLC service by using the encoding method #B.

That is, when sending the data of the first service on the time-frequency resource reserved for the second service, other coding methods may be used besides the first coding method, for example, the above-mentioned second coding method. Therefore, when it is determined that the data of the second service needs to be transmitted on the time-frequency resource reserved for the second service, the first coding method can be used to send the data of the first service on the time-frequency resource reserved for the second service. data, and when it is determined that the time-frequency resources reserved for the second service do not need to be transmitted on the time-frequency resources reserved for the second service, other coding methods (for example, the second coding method) may be used to transmit the data reserved for the second service The data of the first service is sent on the time-frequency resource, so that the overhead on transmission resources can be reduced and the transmission efficiency can be improved.
