Description

Method and device for transmitting data

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting data.

Background

Because of interference and fading in mobile communication, errors will occur during signal transmission, and therefore, an error correction technique or an error detection technique (or, an error correction coding technique or an error detection coding technique) must be applied to digital signals to enhance the capability of data to resist various interferences during transmission in a channel and improve the reliability of the system, and the error correction coding technique or the error detection coding technique may also be referred to as a channel coding technique.

Conventionally, there are known a plurality of coding schemes used in the above channel coding technique, and error correction capabilities of different coding schemes (which may be referred to as channel coding schemes) are different.

In addition, in the prior art, the same coding scheme is used in the transmission process for the same service.

With the development of communication technology, frequency domain resources available for wireless communication are more and more flexible, for example, for data of one service, frequency domain resources reserved by a system for another service can be used for transmission. Accordingly, the requirements of wireless communication on different frequency domain resources for error correction capability may be different, and the requirements of wireless communication on accuracy and reliability cannot be met by using a single coding scheme for the same service.

Disclosure of Invention

The embodiment of the invention provides a method and a device for transmitting data, which can improve the accuracy and reliability of transmission.

In a first aspect, a method for transmitting data is provided, the method comprising: the sending equipment sends first data of a first service through a first time-frequency resource by adopting a first coding mode, wherein the first time-frequency resource comprises a candidate time-frequency resource for transmitting data of a second service; the sending device sends second data of the first service through a second time frequency resource by adopting a second coding mode, wherein the second time frequency resource does not comprise a candidate time frequency resource for transmitting the data of the second service, and the first coding mode is different from the second coding mode.

Or, the first time-frequency resource belongs to a time-frequency resource reserved for the second service; the second time-frequency resource does not belong to the time-frequency resources reserved for the second service.

Therefore, by using the coding modes with different error correction capabilities on different time frequency resources, a proper coding mode can be selected based on the communication conditions on different time frequency resources, so that the accuracy and the reliability of transmission can be improved.

With reference to the first aspect, in a first implementation manner of the first aspect, the method further includes: the sending equipment sends first indication information, wherein the first indication information is used for indicating that the data of the first service transmitted on the time-frequency resource reserved for the second service is transmitted by adopting a first coding mode; or the sending device receives second indication information, where the second indication information is used to indicate that the first service data needs to be transmitted in a first coding mode when the first service data is transmitted on the time-frequency resource reserved for the second service, or the sending device sends first indication information, where the first indication information is used to indicate that the first service data transmitted on the first time-frequency resource is transmitted in the first coding mode; or the sending device receives second indication information, where the second indication information is used to indicate that the first coding mode needs to be adopted for transmission when the data of the first service is transmitted on the first time-frequency resource.

By making the sending device and the receiving device negotiate to make both sides determine that the data of the first service needs to be transmitted on the time-frequency resource reserved for the second service based on the first coding mode, the sending device and the receiving device can transmit the data of the first service on the first time-frequency resource by using the same coding mode, thereby further improving the reliability and accuracy of transmission.

With reference to the first aspect and the foregoing implementation manner of the first aspect, in a second implementation manner of the first aspect, the sending device sends the first data of the first service through the first time-frequency resource in a first coding manner, where the sending device includes: the sending device encodes the first data by adopting a first encoding mode to generate M first code blocks, wherein the M first code blocks comprise N redundant first code blocks and M-N original first code blocks, the original first code blocks are generated according to the first data, the redundant first code blocks are generated according to the original first code blocks, and M & gtN is more than or equal to 1; the transmitting device transmits part or all of the M first code blocks through the first time-frequency resources.

That is, since the first time-frequency resource belongs to the time-frequency resource reserved for the second service, when data of the second service needs to be transmitted, a part of code blocks in M first code blocks formed by the M-N original first code blocks and N redundant first code blocks may be punctured, and then a receiving end may not receive one or more code blocks in the M first code blocks, for this, the first encoding method is: the further encoding process is performed on the basis of the M-N original first code blocks generated from the first data to generate N redundant first code blocks, so that the receiving device can obtain the first data through a redundancy algorithm without receiving one or more of the M first code blocks, thereby further improving the reliability and accuracy of transmission.

With reference to the first aspect and the foregoing implementation manner of the first aspect, in a third implementation manner of the first aspect, the method further includes: the transmitting device transmits third indication information indicating positions of the N redundant first code blocks in the first time-frequency resources.

By causing the transmitting device to notify the receiving device of the positions of the N redundant first code blocks in the first time-frequency resources, the receiving device can be caused to easily determine the original first code block and the redundant first code block of the M first code blocks, and further, the receiving device can be caused to easily recover the first data based on the original first code block and the redundant first code block.

The second time-frequency resource does not belong to the time-frequency resource reserved for the second service, so that when the second code block is transmitted through the second time-frequency resource, the situation that part of the code block is punched does not occur, and therefore a redundant code block does not need to be generated, namely, the second code block can be completely generated according to the second data, thereby reducing the cost on the transmission resource and improving the transmission efficiency.

With reference to the first aspect and the foregoing implementation manner of the first aspect, in a fifth implementation manner of the first aspect, the method further includes: and the sending equipment sends the data of the second service through a third time-frequency resource, wherein the third time-frequency resource belongs to the time-frequency resources reserved for the second service except the first time-frequency resource.

That is, when the data of the first service is transmitted on the time-frequency resource reserved for the second service, other coding schemes, such as the second coding scheme described above, may be used in addition to the first coding scheme.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As used in this specification, the terms "component," "module," "system," and the like are intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components can reside within a process and/or thread of execution and a component can be localized on one computer and/or distributed between 2 or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from two components interacting with another component in a local system, distributed system, and/or across a network such as the internet with other systems by way of the signal).

The scheme of the embodiment of the invention can be applied to the existing cellular Communication systems, such as Global System for Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), and other systems, and the supported Communication is mainly directed to voice and data Communication. The solution of the embodiment of the present invention may also be applied to a next generation communication system, such as a 5G communication system.

The next generation mobile communication system will not only support the traditional communication service, but also support URLLC service (english name: Ultra-Reliable and Low Latency Communications), which is generally an emergency service, and has high requirements for transmission reliability and transmission delay, generally requiring 99.999% transmission reliability within 1 ms. In order to meet the service requirements of the URLLC service on ultra-high reliability and ultra-low delay, the system needs to allocate sufficient frequency domain resources for the URLLC service to transmit the URLLC service, but the URLLC service is generally a sudden emergency service, and the service data packet is generally small, so that when no service arrives, the resources allocated for the URLLC service will cause a certain waste of resources. Meanwhile, for the eMBB service (English name: enhanced Mobile BroadBand band), a large frequency domain resource is required due to the huge service data. Meanwhile, the available bandwidth of the wireless communication system is limited, the total frequency domain resources and the frequency band requirements of different services and the frequency band allocation schemes of different services have the problems of deficiency and redundancy, and the scheme according to the embodiment of the invention can effectively solve the problem of resource allocation.

118 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which a network device transmits through a single antenna to all its terminal devices.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. 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 (PLMN) Network, a D2D Network, an M2M Network, or other networks, and fig. 1 is a simplified schematic diagram for example, and the Network may further include other Network devices, which are not shown in fig. 1.

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

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

In the embodiment of the present invention, "the time-frequency resource reserved for the second service" may be understood as that the communication system or the communication protocol specifies that the time-frequency resource reserved for the second service is only used for transmitting data of the second service; in other words, the communication system or the communication protocol provides that the time-frequency resources reserved for the second service are prohibited from being used for transmitting data of services (e.g., the first service) other than the second service.

Alternatively, the term "reserved time-frequency resources for the second service" may also be understood as that the communication system or the communication protocol specifies that the reserved time-frequency resources for the second service are preferentially used for transmitting the data of the second service, for example, when the data of the second service does not need to be transmitted, the reserved time-frequency resources for the second service may be used for transmitting the data of other services (for example, the first service); when the data of the second service needs to be transmitted, the time-frequency resource reserved for the second service needs to ensure the transmission of the data of the second service first, and on the premise of meeting the transmission of the data of the second service, the remaining time-frequency resources in the time-frequency resource reserved for the second service can be utilized to transmit the data of other services (for example, the first service).

Or, the "time-frequency resource reserved for the second service" may also be understood as a candidate time-frequency resource for transmitting data of the second service, where data that can be transmitted through the candidate time-frequency resource may include data of the first service and data of the second service, and a transmission priority of the second service is higher than a transmission priority of the first service, or in other words, when data of the first service and data of the second service that need to be transmitted through the candidate time-frequency resource in the same time period occur, data of the second service that is transmitted through the candidate time-frequency resource is preferentially used, specifically, data of the second service may be transmitted through the candidate time-frequency resource first, and after data of the second service that is transmitted through the candidate time-frequency resource is completed, data of the first service may be transmitted through the candidate time-frequency resource; or, when a part of the candidate time-frequency resource can satisfy the transmission of the data of the second service, the data of the first service can be transmitted through the rest of the candidate time-frequency resource.

By way of example and not limitation, the first service may be enhanced mobile internet (eMBB) service. The second service may be an ultra reliable and ultra Low Latency (URLLC) service.

Specifically, the international telecommunication Union Radio Communication commission (ITU-R) defines 3 major application scenarios of the future 5G, which are Enhanced Mobile internet service (eMBB), mass connected internet of things service (mtc), and Ultra high reliability and Ultra Low delay service (URLLC), and defines capability requirements for the 5G network from 8 dimensions, such as throughput, delay, connection density, and spectral efficiency. The eMBB service mainly requires a high rate, a wide coverage, a transmission delay, and mobility. The main requirements of URLLC service are very high reliability, very low mobility and transmission delay, which generally requires that the wireless air interface reaches 99.999% of transmission reliability within 1 millisecond (ms).

For URLLC service, in order to guarantee the time delay requirement, the service is required to be transmitted immediately after reaching the base station, and a certain time-frequency resource is required for transmitting URLLC data. In a 5G system, different services may be multiplexed in one carrier, and the Multiplexing mode may be Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM). In order to ensure the service requirement of the URLLC, in the present research and standard discussion, a band resource (i.e., an example of a time-frequency resource reserved for the second service) is intended to be reserved for the URLLC, and it is ensured that the URLLC always transmits a time-frequency resource when the service arrives, i.e., as shown in fig. 2, the URLLC is frequency-division multiplexed with other services (e.g., eMBB services) in the same carrier.

In the embodiment of the invention, the URLLC service and the eMMC service are subjected to frequency division multiplexing, the eMMC service can temporarily use resources reserved for the URLLC service, and on the resources reserved for the URLLC service, when the URLLC service (specifically, data of the service) arrives, if the eMMC service is transmitted on the resources reserved for the URLLC service, the eMMC service which is being transmitted is punched, and the URLLC service is transmitted at the punching position.

For convenience of understanding and explanation, the method for transmitting data according to the embodiment of the present invention will be described in detail below with the eMBB service as the first service and the URLLC service as the second service.

Fig. 3 is a schematic interaction diagram of a method 300 of transmitting data in an embodiment of the invention.

Specifically, in S210, the transmitting device (or the encoding end) may encode the data of the eMBB service (i.e., an example of the first data of the first service, which will be referred to as data # a for ease of understanding and distinction hereinafter) that needs to be transmitted to the receiving device (or the decoding end) by using the encoding method # a (i.e., an example of the first encoding method).

By way of example and not limitation, in the embodiment of the present invention, the encoding scheme # a may be the following encoding scheme.

Here, the object to be encoded in the encoding scheme # a may be data subjected to source encoding processing. That is, the coding scheme # a may be a channel coding scheme.

In particular, source coding is a transformation of source symbols for the purpose of improving communication efficiency, or for reducing or eliminating source redundancy. Specifically, a method is found for the statistical characteristics of the source output symbol sequence, the source output symbol sequence is converted into the shortest code word sequence, the average information amount loaded by each code element of the shortest code word sequence is maximized, and simultaneously, the original symbol sequence can be recovered without distortion.

One of the roles of source coding is to try to reduce the number of symbols and to reduce the symbol rate, known as data compression; the other function is to convert the analog signal of the information source into a digital signal so as to realize the digital transmission of the analog signal.

Channel coding is a theory and method implemented by channel encoders and decoders for improving channel reliability. Channel coding is roughly divided into two categories:

① the theorem of channel coding theoretically solves the existing problems of an ideal encoder and decoder, namely the possibility of the maximum information rate that the channel can transmit and the transmission problem when the maximum information rate is exceeded.

② constructive encoding methods and the performance limits that these methods can achieve.

In transmission, digital signals often cause errors in transmitted data streams due to various reasons, and thus, the receiving end generates phenomena such as image jump, discontinuity, mosaic, and the like. Therefore, through the link of channel coding, the digital stream is correspondingly processed, so that the system has certain error correction capability and anti-interference capability, and the occurrence of error codes in code stream transmission can be greatly avoided. The error code processing techniques include error correction, interleaving, linear interpolation, and the like.

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

The essence of channel coding is to increase the reliability of the communication. However, the channel coding reduces the transmission of useful information data, and the process of channel coding is to add some code elements in the source data code stream, so as to achieve the purpose of error judgment and correction at the receiving end, which is the overhead that we often say. In a channel with a fixed bandwidth, the total transmission code rate is also fixed, and since the channel coding increases the data amount, the result can only be at the cost of reducing the transmission useful information code rate. The useful bit number is divided by the total bit number to obtain the coding efficiency, which is different for different coding modes.

By way of example and not limitation, in the embodiment of the present invention, the encoding scheme # a may be as follows:

for example, the transmitting device may use the existing channel coding scheme (hereinafter, for ease of understanding, referred to as coding scheme # A-1) to encode data (e.g., data # A after source coding processing)) The encoding process is performed to generate a plurality of original code blocks (i.e., an example of M-N original first code blocks, which will be referred to below for ease of understanding and distinction: original code Block # A₁Original code Block # A_M-N)。

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

By way of example and not limitation, the coding scheme # a-1 may be, for example, a block code coding scheme, a convolutional code coding scheme, a polar code coding scheme, a turbo code coding scheme, or the like.

The process of the transmitting device performing the encoding process on the data # a based on the encoding method # a-1 may be similar to the prior art, and a detailed description thereof is omitted here to avoid redundancy.

Thereafter, the transmitting device may encode the original code block # A in the coding mode # A-2₁Original code Block # A_M-NFurther processing is performed to obtain a plurality of redundancy code blocks (i.e., an example of N redundancy first code blocks, hereinafter, for ease of understanding and distinction, denoted as redundancy code block # A)_M-N+1Redundancy code Block # A_M)。

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

By way of example, and not limitation, in embodiments of the invention, the original code block # A may be encoded₁Original code Block # A_M-NAs the input parameters, for example, a predetermined weight may be assigned to each input parameter, and each input parameter may be subjected to arithmetic processing (for example, addition or subtraction) using a predetermined algorithm to output the redundancy code block # a_M-N+1Redundancy code Block # A_M。

In addition, in the embodiment of the present invention, the redundancy code blocks may include the original code block # a₁Original code Block # A_M-NOr the redundancy code block may be based on the original code block # a₁Original code Block # A_M-NGenerated such that a portion (e.g., one) of the code blocks in the original code block is missing (e.g., typed by a transmitting device) during transmissionHole-induced loss), the missing code block can be recovered based on the original code block without the loss and the redundant code block, and thus, the receiving apparatus can accurately and reliably recover the data # a that the transmitting apparatus needs to transmit.

It should be noted that, in the embodiment of the present invention, the number of the redundancy code blocks may be one or more, and the embodiment of the present invention is not particularly limited, and when the redundancy code block is one, the one redundancy code block may include the original code block # a₁Original code Block # A_M-NThe component of each original code block (or, data generated by processing the component of each original code block by a predetermined algorithm); when the redundancy code block is plural, the plural redundancy code blocks may include an original code block # A₁Original code Block # A_M-NFor example, each redundancy code block may include the original code block # a (or data generated by subjecting the components of each original code block to a prescribed algorithm)₁Original code Block # A_M-NOr one redundancy code block may include the original code block # a₁Original code Block # A_M-NA portion of the original code block (or data generated by subjecting the portion of the original code block to a predetermined algorithm), and another redundancy code block may include the original code block # a₁Original code Block # A_M-NOf the code block (or, data generated by subjecting the component of the code block to a predetermined algorithm).

By way of example and not limitation, the encoding scheme # a (or encoding scheme # a-2) may be an outer code (outer code) encoding scheme. The specific process and method of the outer code encoding method may be similar to those of the prior art, and detailed descriptions thereof are omitted here for avoiding redundancy.

It should be understood that the specific processes of the above-mentioned encoding mode # a are only exemplary, and the embodiments of the present invention are not limited thereto.

By way of example and not limitation, in the embodiment of the present invention, the coding scheme # a may be a joint coding scheme (i.e., an example of the first coding scheme), that is, a plurality of coding units (or code blocks) may be generated by encoding certain data (hereinafter, referred to as data # β for easy understanding and distinction) by using the joint coding scheme, and the data # β may be decoded without passing through all of the coding units in the plurality of coding units, or the data # β may be decoded by passing through only a part of the coding units in the plurality of coding units.

In addition, as a coding scheme different from the joint coding scheme, in the embodiment of the present invention, an individual coding scheme (i.e., an example of the second coding scheme) may be mentioned, in which a plurality of coding units (or code blocks) can be generated after coding data (hereinafter, referred to as data # γ for easy understanding and distinction) in the individual coding scheme, and the data # γ can be decoded only by all of the coding units in the plurality of coding units, or the data # γ cannot be decoded only by some of the coding units in the plurality of coding units.

For example, in the embodiment of the present invention, the encoding scheme # a may be the following encoding scheme:

the transmitting device may first divide the data into multiple original code blocks, (i.e., an example of M-N original first code blocks, denoted as original code block # B)₁Original code block # B_M-N) Here, the M-N may be an integer greater than or equal to 1, that is, the number of original code blocks may be at least one.

Thereafter, the transmitting device can encode the original code block # B in the coding scheme # A-2₁Original code block # B_M-NFurther processing is performed to obtain a plurality of redundancy code blocks (i.e., an example of N redundancy first code blocks, denoted as redundancy code block # B)_M-N+1Redundant code Block # B_M). Here, N may be an integer greater than or equal to 1, that is, the number of redundancy code blocks may be at least one.

Also, by way of example and not limitation, in embodiments of the invention, the original code block # B may be encoded₁Original code block # B_M-NAs the input parameters, and for example, a prescribed weight may be assigned to each input parameter, and each input parameter may be subjected to a predetermined algorithmThe input parameter is subjected to arithmetic processing (for example, addition or subtraction) to output a redundant code block # B_M-N+1Redundant code Block # B_M。

Thereafter, as an example and not by way of limitation, the transmitting device may perform encoding processing on the M first code blocks by using the existing channel coding scheme (coding scheme # a-1) to generate M first code blocks (denoted as code block # a)₁Code Block # A_M) The coding scheme # A-1 may be, for example, a block code coding scheme, a convolutional code coding scheme, a polar code coding scheme, a turbo code coding scheme, or the like.

Moreover, the process of the transmitting device performing the encoding processing on the M first code blocks based on the encoding mode # a-1 may be similar to that in the prior art, and here, detailed description thereof is omitted to avoid redundancy.

For another example, in the embodiment of the present invention, for example, the communication system or the communication protocol may provide that the first code block of the first service transmitted on the time-frequency resources reserved for the second service is not punctured, in which case, the transmitting device may also only puncture the original code block # a₂Original code Block # A_M-NAs the input parameters, for example, a predetermined weight may be assigned to each input parameter, and each input parameter may be subjected to arithmetic processing (for example, addition operation, subtraction operation, or the like) using a predetermined algorithm to output the redundancy code block # a_M-N+1Redundancy code Block # A_M. I.e., the original code block # A₁Or may not participate in outer code encoding, in which case the redundancy code block may not include the original code block # A₁May be based on the original code block # a₂Original code Block # A_M-NAnd (4) generating.

Thus, the M code blocks (i.e., an example of the M first code blocks, hereinafter referred to as code block # A for ease of understanding and distinction) generated by encoding the data # A by the encoding system # A₁Code Block # A_M) Including the original code block # A₁Original code Block # A_M-NAnd redundancy code Block # A_M-N+1Redundancy code Block # A_M。

Thereafter, the transmitting device may be secondary to the URLLC service (i.e., of the second service)Example) is determined to carry the code block # a in reserved time-frequency resources (hereinafter, reserved resources are referred to for ease of understanding and distinction)₁Code Block # A_MTime frequency resource (hereinafter, for convenience of understanding and distinction, denoted as time frequency resource # A)₁Time-frequency resource # A_M). And code block # A₁Code Block # A_MLoaded in the time frequency resource # A₁Time-frequency resource # A_MWherein the code block # A₁Code Block # A_MAnd the time frequency resource # A₁Time-frequency resource # A_MThere may be a one-to-one correspondence, i.e., each code block may be carried on the corresponding time-frequency resource.

It should be noted that, in the embodiment of the present invention, the time-frequency resource # a₁Time-frequency resource # A_MMay be all of the reserved resources, or the time-frequency resource # A₁Time-frequency resource # A_MOr may be a part of the reserved resources, and the embodiment of the present invention is not particularly limited.

At S220, the transmitting device may transmit over time-frequency resource # a₁Time-frequency resource # A_MSome or all of the time-frequency resources in (1), transmit code block # A₁Code Block # A_MOf the code block(s).

Specifically, in the embodiment of the present invention, the code block # A is transmitted₁Code Block # A_MThere may be a case where data of URLLC service (i.e., an example of data of the second service) needs to be transmitted due to time-frequency resource # a₁Time-frequency resource # A_MBelongs to the time-frequency resource reserved for URLLC service, therefore, the time-frequency resource # A may exist₁Time-frequency resource # A_MIs needed for transmitting data of URLLC traffic. Thus, for code block # A₁Code Block # A_MMay include the following:

case 1

The transmitting device may use the time-frequency resource # a when there is no need to transmit data of the URLLC service₁Time-frequency resource # A_MIs transmitted (i.e., an example of the first time-frequency resource)Code block # A₁Code Block # A_MAll code blocks in (2).

Case 2

When data of URLLC service needs to be transmitted and time frequency resource # A is removed from reserved resources₁Time-frequency resource # A_MWhen the other time-frequency resources (hereinafter, for convenience of understanding and distinction, referred to as the remaining time-frequency resources) can meet the transmission requirement of the URLLC service, the sending device may use the time-frequency resource # a₁Time-frequency resource # A_MTransmits the code block # a on all time-frequency resources (i.e., an example of the first time-frequency resource) of₁Code Block # A_MAnd the sending device may send data of the URLLC service through part or all of the remaining time-frequency resources (i.e., an example of the third time-frequency resource), where a process of the generating device sending the data of the URLLC service may be similar to that in the prior art, and here, detailed descriptions thereof are omitted to avoid redundancy.

Case 3

When 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 transmitting device may use the remaining time-frequency resources and time-frequency resource # a₁Time-frequency resource # A_MThe data of the URLLC service is transmitted by part of the time-frequency resources in (a), i.e., the transmitting device can transmit data to the code block # a₁Code Block # A_MSome (for example, 1) code blocks are punctured, and data of the URLLC service is carried in the time-frequency resources corresponding to the punctured code blocks. Thus, in this case, the transmitting device uses time-frequency resource # A₁Time-frequency resource # A_MTransmits the code block # a using a portion of the time-frequency resources (i.e., another instance of the first time-frequency resources)₁Code Block # A_MIs selected. And, the transmitting device can pass the remaining time-frequency resource and time-frequency resource # A₁Time-frequency resource # A_MWherein, a process of the generating device based on sending the data of the URLLC service may be similar to the prior art, and a detailed description thereof is omitted here for avoiding redundancy。

In the above case, the code block punctured by the transmitting device may belong to code block # a₁Code Block # A_MThe original code block in (1) may also belong to code block # A₁Code Block # A_MRedundant code blocks in (1) embodiments of the present invention are not particularly limited.

The number of code blocks punctured by the transmitting device is merely an exemplary description, and the embodiments of the present invention are not particularly limited as long as the receiving device can accurately recover the data that the generating device needs to transmit based on the code blocks that are not punctured.

Next, the acquisition process of the data # a by the receiving apparatus will be described in detail.

As described above, the transmitting device passes through time-frequency resource # A₁Time-frequency resource # A_MTransmits a code block # a using some or all of the time-frequency resources (i.e., an example of the first time-frequency resources)₁Code Block # A_MAfter part or all of the code blocks, the receiving device may detect the reserved resources and receive the code block of the eMBB service carried in the reserved resources, i.e., the code block # a, in S220₁Code Block # A_MOf the code block(s).

It should be noted that, in the embodiment of the present invention, the sending device and the receiving device may determine, through Downlink Control Information (DCI): the location of the code block of the eMBB service carried in the reserved resource, or the time-frequency resource (i.e., an example of the first time-frequency resource) of the code block for carrying the eMBB service is reserved.

When encoding data of the eMBB service using the outer code encoding scheme (i.e., the encoding scheme # a), the receiving device needs to distinguish between the original code block and the redundant code block of the transmitted eMBB service.

By way of example and not limitation, the transmitting device may also transmit indication information indicating a location of time-frequency resources for carrying a redundancy code block (i.e., an example of the third indication information) to the receiving device.

Or, for example, the transmitting device may also transmit indication information (i.e., another example of the third indication information) indicating a location of time-frequency resources for carrying the original code block to the receiving device.

Thus, the receiving device can receive the code block # A from the third indication information₁Code Block # A_MWhere redundant code blocks and original code blocks are identified.

It should be understood that the above-listed method and process for the receiving device to distinguish the original code blocks and the redundant code blocks of the transmitted eMBB service are only exemplary, and the present invention is not limited thereto, for example, the communication system or the communication protocol may also specify the arrangement or the position relationship of the original code blocks and the redundant code blocks in advance, so that the transmitting device may transmit the original code blocks and the redundant code blocks according to the above specification, and the receiving device may identify the original code blocks and the redundant code blocks according to the above specification.

At S230, the receiving device may be based on the received code block of the eMBB traffic (i.e., the code block # a described above)₁Code Block # A_MSome or all of the code blocks) of the code blocks, the code block # a is coded according to a coding scheme # a (e.g., coding scheme # a-1 and/or coding scheme # a2)₁Code Block # A_MDecoding processing is performed to acquire the above data # a.

By way of example and not limitation, for example, the receiving device may first attempt to perform decoding processing on an original code block among code blocks of the received eMBB traffic using coding scheme # a-1.

If normal decoding is possible, the receiving device may determine to be code block # A₁Code Block # A_MHas not been lost (e.g., not punctured), and thus the decoded data can be considered as the numberAccording to # A.

If it cannot decode normally, the receiving device may determine that code block # A₁Code Block # A_MIn this case, the receiving device may recover the original code block # a based on the received original code block and the redundant code block in the code block of the eMBB service according to the coding scheme # a-2₁Original code Block # A_M-NFurther, the original code block # A is coded based on the coding scheme # A-1₁Original code Block # A_M-NDecoding processing is performed, thereby acquiring the above data # a.

For another example, the receiving device may recover the original code block # a based on the original code block and the redundant code block in the code blocks of the received eMBB service directly according to the coding scheme # a-2₁Original code Block # A_M-NFurther, the original code block # A is coded based on the coding scheme # A-1₁Original code Block # A_M-NDecoding processing is performed, thereby acquiring the above data # a.

The receiving device recovers the original code block # a from the original code block and the redundant code block among the code blocks of the coding scheme # a-2 and the received eMBB service₁Original code Block # A_M-NMay be that the transmitting device is according to the coding scheme # a-2 and the original code block # a₁Original code Block # A_M-NGenerating an original code block and a redundant code block among code blocks of the received eMBB traffic to recover a redundant code block # A_M-N+1Redundancy code Block # A_MThe reverse process of (1) is omitted here for the sake of avoiding redundancy.

By way of example and not limitation, in the embodiment of the present invention, when the transmitting device and the receiving device transmit data of the eMBB service (i.e., an example of the first service) using the time-frequency resources reserved for the URLLC service (i.e., an example of the second service), the used coding scheme (e.g., the coding scheme # a described above) may be specified by a communication system or a 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 resource reserved for the URLLC service, so that the sending device and the receiving device can determine whether the coding scheme adopted on the resource reserved for the URLLC service is different from the coding scheme adopted on the resource allocated to the eMBB service by system predefining or by system message, and further, can indicate which coding scheme is specifically adopted on the resource reserved for the URLLC service by system predefining or by system message.

Alternatively, in the embodiment of the present invention, the sending device and the receiving device may also determine (e.g., through signaling) a coding scheme used when sending data of the eMBB service using the time-frequency resources reserved for the URLLC service.

For example, one of the transmitting apparatus and the receiving apparatus (e.g., a network apparatus of the transmitting apparatus and the receiving apparatus) may transmit, to the other of the transmitting apparatus and the receiving apparatus (e.g., a terminal apparatus of the transmitting apparatus and the receiving apparatus), indication information indicating a coding scheme used when transmitting data of the eMBB service using the time-frequency resources reserved for the URLLC service (i.e., an example of the first indication information or the second indication information).

Alternatively, one of the transmitting device and the receiving device (e.g., a network device of the transmitting device and the receiving device) may transmit an indication indicating that the first time-frequency resource (e.g., time-frequency resource # a) is being used to the other of the transmitting device and the receiving device (e.g., a terminal device of the transmitting device and the receiving device)₁Time-frequency resource # A_M) Indication information of a coding scheme used when transmitting data of the eMBB service (i.e., an example of the first indication information or the second indication information). Note that, in this case, the first time-frequency resource may be determined by an indication of 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 may indicate, for example, through Downlink Control Information (DCI), a coding scheme adopted by the terminal device for data transmission scheduled by the DCI, for example, for the eMBB service, a system defaults to a channel coding scheme, such as coding scheme # a-1, and notify, in the DCI, whether the coding scheme adopted for data transmission scheduled by the DCI is different from coding scheme # a-1, and further, may indicate, through the DCI or a system message, which coding scheme is different from the default channel coding scheme.

The data of the first service is transmitted on the time-frequency resource reserved for the second service by the transmitting equipment and the receiving equipment based on the first coding mode, so that the transmitting equipment and the receiving equipment can transmit the data of the first service on the first time-frequency resource by using the same coding mode, and the reliability and the accuracy of transmission can be further improved.

According to the method for transmitting data of the embodiment of the 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, may cause a portion of the M first code blocks, which are composed of the M-N original first code blocks and the N redundant first code blocks, to be punctured, thereby causing the receiving end to fail to receive one or more of the M first code blocks, in this case, the first encoding scheme is further performed on the basis of the M-N original first code blocks generated from the first data, to generate N redundant first code blocks, enabling the receiving device to, without receiving one or more of 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 transmitting device may encode data of the eMBB service (i.e., an example of the second data of the first service, hereinafter referred to as data # B for ease of understanding and distinction) that needs to be transmitted to the receiving device, using an encoding method # B (i.e., an example of the second encoding method).

Here, the object to be encoded by the encoding method # B may be data subjected to source encoding processing. That is, the coding scheme # B may be a channel coding scheme.

For example, the transmitting device may perform encoding processing on data (e.g., data # B subjected to source encoding processing) in the encoding scheme # B to generate a plurality of original code blocks (i.e., an example of the second code block).

By way of example and not limitation, the coding scheme # B may be, for example, a block code coding scheme, a convolutional code coding scheme, a polar code coding scheme, a turbo code coding scheme, or the like.

The process of the transmitting device encoding the data # B based on the encoding method # B may be similar to that of the prior art, and a detailed description thereof is omitted here to avoid redundancy.

In the embodiment of the present invention, the encoding scheme # B may be the same as or different from the encoding scheme # a-1, and the embodiment of the present invention is not particularly limited.

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

At S250, the transmitting device transmits a second code block to the receiving device through the second time-frequency resource.

Accordingly, in S250, the receiving device may receive the second code block through the second time-frequency resource, and in S260, the receiving device may perform decoding processing on the second code block based on the coding mode # B, so as to obtain the data # B.

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

That is, in the embodiment of the present invention, the coding scheme # B is different from the coding scheme # a, or, for the eMBB service, the coding scheme used in the transmission process on the time-frequency resource reserved for the URLLC service is different from the coding scheme used in the transmission process on the time-frequency resource other than the time-frequency resource reserved for the URLLC service.

It should be understood that the above-mentioned coding scheme # a is only an example of the first coding scheme of the embodiment of the present invention, the first coding scheme of the embodiment of the present invention is not particularly limited, and the first coding scheme of the embodiment of the present invention may be another channel coding scheme in the prior art as long as the first coding scheme of the embodiment of the present invention is different from the second coding scheme.

For example, in another embodiment of the present invention, the encoding method # a may also be an encoding method, where a sending device (or an encoding device) may encode the data # a by using an encoder (for example, a fountain code encoding method) to generate a plurality of (i.e., M, where the value of M may be infinite) encoding units, or an infinitely long codeword sequence, where the M encoding units may be divided into a plurality of encoding unit combinations, where any one encoding unit combination may include some or all of the M encoding units, and an intersection between any two encoding unit combinations in the plurality of encoding unit combinations is an empty set, or at least one different encoding unit exists between any two encoding unit combinations in the plurality of encoding unit combinations. Data # a can be obtained by decoding any combination of the encoding units.

Thereafter, the transmitting device may determine, from the time-frequency resources (or candidate time-frequency resources) reserved for the URLLC service (i.e., an example of the second service), the time-frequency resources for carrying any one coding unit combination of the above-mentioned multiple coding unit combinations (hereinafter, for convenience of understanding and distinction, it is noted that coding unit combination # a, i.e., the coding unit combination # a includes some or all of the M coding units), and transmit coding unit combination # a. Alternatively, the transmitting device may transmit the partial codeword (or the sub-codeword sequence) in the infinite codeword sequence to the receiving device until receiving the acknowledgement message fed back by the receiving device.

Additionally, optionally, the method further comprises:

and the sending equipment sends third data of the first service through a third time-frequency resource in a second coding mode, wherein the third time-frequency resource belongs to the time-frequency resource reserved for the second service.

And the receiving equipment receives third data of the first service through a third time-frequency resource by adopting a second coding mode, wherein 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 may determine that the URLLC service does not need to be transmitted, the sending device may also send the data of the eMBB service on the time-frequency resource reserved for the URLLC service by using the coding method B.

Accordingly, in the embodiment of the present invention, before the transmitting device and the receiving device use the coding scheme # a to transmit the data of the eMBB service on the time-frequency resources reserved for the URLLC service, the transmitting device and the receiving device may further first determine whether the data of the URLLC service will be transmitted on the time-frequency resources reserved for the URLLC service.

If yes, the sending device and the receiving device may use the coding mode # a to transmit data of the eMBB service on the time-frequency resource reserved for the URLLC service.

If the judgment result is no, the sending device and the receiving device can use the coding mode # B to transmit the data of the eMBB service on the time-frequency resource reserved for the URLLC service.
