METHOD FOR SENDING OR RECEIVING DATA AND COMMUNICATION DEVICE

Description

TECHNICAL FIELD

[0001] This application relates to the field of communications technologies, and more specifically, to a data sending method and an apparatus.BACKGROUND

[0002] In a long term evolution (Long Term Evolution, LTE) system, a base station does not know channel quality before sending downlink data to a terminal device. As wireless communications systems continuously evolve, increasingly high data transmission reliability is required. For example, in a fifth-generation mobile communications technology (also referred to as 5G), ultra-reliable data transmission is required in an ultra-reliable and low latency communications (Ultra-reliable and low latency communications, URLLC) scenario, and a block error rate needs to be even less than 1e-9 in some application scenarios. It is readily to figure out that it is difficult to ensure transmission reliability when the base station sends downlink data without knowing channel quality at all.

[0003] There is currently no feasible solution in the industry to meet a high requirement of data transmission reliability in a future communications system.

[0004] The invention is defined by the appended claims. Examples, aspects and technical descriptions of methods and / or apparatuses in the description and / or drawings which are not covered by the claims are presented not as embodiments of the invention but as background art or examples useful for understanding the invention.

[0005] According to a first aspect, this application provides a data sending method, where the method includes: obtaining, by a terminal device, a modulation order, a code rate, or spectral efficiency; selecting, by the terminal device, an index of a reference channel quality indicator (CQI) from a prestored mapping table based on the obtained modulation order, code rate, or spectral efficiency, where the mapping table includes a mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency; sending, by the terminal device, first indication information to a network device, where the first indication information is used to indicate the index of the reference CQI; receiving, by the terminal device, second indication information from the network device, where the second indication information is used to indicate an index of a target channel quality indicator (CQI); and determining, by the terminal device from the mapping table based on the index of the target CQI, at least one of a modulation order, a code rate, and a coding scheme that are corresponding to the target CQI.

[0006] In this embodiment of this application, the terminal device and the network device prestore the mapping table that records at least a mapping relationship between a CQI index and a modulation order, a code rate, and / or spectral efficiency. The CQI index is a sequence number obtained after channel quality is quantified, and therefore each CQI index can reflect the channel quality. The terminal device first measures channel quality, selects a CQI index that reflects current channel quality from the prestored mapping table, and feeds back the CQI index to the network device. In this way, with reference to the index, of the reference CQI, fed back by the terminal device and with reference to a current network resource status, the network device determines a resource allocation and modulation manner, a coding scheme, and the like that are used to send downlink data, and returns the index of the finally selected target CQI to the terminal device. Subsequently, the network device may send data to the terminal device by using the code rate, the modulation order, the coding scheme, and the like that are corresponding to the index of the target CQI, thereby improving data transmission reliability.

[0007] In addition, a process of measuring the channel quality by the terminal device may be implemented according to the prior art, and is not described in detail herein.

[0008] With reference to the first aspect, in some implementations of the first aspect, the mapping table further records a mapping relationship between a CQI index and a coding scheme.

[0009] A coding scheme is a code that is used to code a data channel. Optionally, the coding scheme in this embodiment of this application may include a polar code (Polar code), a low density parity check (LDPC) BG2, and an LDPC BG1. Specifically, the LDPC BG2 represents an LDPC code obtained based on a base graph BG2. The LDPC BG1 represents an LDPC code obtained based on a base graph BG1.

[0010] According to a second aspect, this application provides a data sending method, where the method includes: determining, by a network device, a modulation order, a code rate, or spectral efficiency that needs to be used to send data; selecting, by the network device, an index of a target CQI from a prestored mapping table based on the determined modulation order, code rate, or spectral efficiency, where the mapping table includes a mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency; and sending, by the network device, second indication information, where the second indication information is used to indicate the index of the target CQI.

[0012] With reference to the second aspect, in some implementations of the second aspect, the mapping table further includes a mapping relationship between a CQI index and a coding scheme.

[0013] With reference to the second aspect, in some implementations of the second aspect, the modulation order, the code rate, or the spectral efficiency that needs to be used to send data is determined by the network device based on an index of a reference CQI.

[0014] Further, in some implementations of the second aspect, the method further includes: receiving, by the network device, first indication information from a terminal device, where the first indication information is used to indicate the index of the reference CQI.

[0015] It is applicable to both the data sending methods of the first aspect and the second aspect that, in some implementations, any mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency in the mapping table meets a mapping relationship shown in Table A or Table B.

[0017] It should be noted that a code rate, in each table provided in this embodiment of this application, divided by 1024 is an actual code rate.

[0018] Further, a plurality of mapping tables designed in this embodiment of this application may be applied to different reliability requirements. A simple and feasible solution is provided for a plurality of scenarios with different block error rate BLER requirements.

[0019] It is applicable to both the data sending methods of the first aspect and the second aspect that, in some implementations, a first value set of the modulation order in the mapping table corresponds to a first coding scheme in the coding scheme, a second value set of the modulation order corresponds to a second coding scheme in the coding scheme, and the first value set and the second value set include at least one value of the modulation order.

[0020] In this implementation, there may be a mapping relationship between the coding scheme and a value of the modulation order. For example, when the value of the modulation order is equal to 2 and 4, the coding scheme uses the LDPC BG2; when the modulation order is equal to 6, the coding scheme uses the LDPC BG1. For another example, when the value of the modulation order is equal to 2, the coding scheme uses the polar code; when the value of the modulation order is equal to 4 and 6, the coding scheme uses the LDPC BG2. Certainly, there may be other mapping relationships that are not enumerated one by one herein.

[0021] It should be understood that the first coding scheme and the second coding scheme herein only represent two different coding schemes, but specific codes used by the first coding scheme and the second coding scheme are not limited. Similarly, the first value set and the second value set only represent two different value sets, and each value set includes at least one value of the modulation order. Apparently, the modulation order may not be limited to have only two value sets, for example, may have three or four value sets. A relationship between any two value sets meets a relationship between the first value set and the second value set herein.

[0023] In this embodiment of this application, the terminal device and the network device prestore the mapping table that records at least a mapping relationship between a CQI index and a modulation order, a code rate, and / or spectral efficiency. The CQI index is a sequence number obtained after channel quality is quantified, and therefore each CQI index can reflect the channel quality. The terminal device first measures channel quality, selects a CQI index that reflects current channel quality from the prestored mapping table, and feeds back the CQI index to the network device. In this way, data transmission reliability can be improved.

[0069] For ease of understanding, related concepts in the embodiments of this application are first described briefly.

[0070] As a next-generation wireless communication technology, 5G has gained extensive attention and is widely researched by the 3GPP and other international organizations for standardization. A channel coding technology is a commonly used method in the field of communications technologies to improve data transmission reliability. It is proposed in 5G that a low density parity check (Low Density Parity Check, LDPC) code is used for a data channel, and a polar code is used for a control channel.

[0071] The LDPC code is a type of linear block code with a sparse parity check matrix, to be specific, there are far more zero elements than non-zero elements in a parity check matrix of the LDPC code, and the non-zero elements are irregularly distributed. A linear block code with a code length equal to N and an information sequence length equal to K may be uniquely determined by a parity check matrix of the linear block code. The LDPC code not only has good performance close to a Shannon limit, but also has relatively low decoding complexity and a flexible structure. The LDPC code is a research hotspot in the field of channel coding in recent years, and has been widely used in fields such as deep space communications, fiber optic communications, and a satellite digital video and audio radio service. A quasi-cyclic low-density parity-check (Quasi-Cyclic Low-Density Parity-Check, QC-LDPC) code is a subclass of the LDPC code. A parity check matrix (parity check matrix) of the QC-LDPC code is obtained by extending a base graph, and the parity check matrix of the QC-LDPC is characterized by simple description and easy construction. In 3GPP TS38.212.V15.0.0 (2017-12), two different base graphs (base graph, BG) of the LDPC code are introduced for LDPC coding: a BG 1 and a BG 2. For details, refer to the document 3GPP TS38.212.V15.0.0 (2017-12).

[0072] The polar code is also a linear block code with a coding matrix (also referred to as a generation matrix) G N and a coding process x 1 N = u 1 N ⋅ G N . μ 1 N = μ 1 , μ 2 , … , μ N is a binary row vector with a length (a code length) of N, and is also referred to as a to-be-coded vector. N=2 n< , and n is a positive integer. x 1 N is a coded mother codeword. G N is an N × N matrix, and G N = F 2 ⊗ log 2 N . is F 2 ⊗ log 2 N defined as a kronecker (Kronecker) product of log2 N< matrices F 2 , where . F 2 = 1 0 1 1 Addition and multiplication operations in the foregoing formulas are all addition and multiplication operations in a binary Galois field. In the coding process of the polar code, some bits in u 1 N are used to carry information, and are referred to as an information bit set. A set of indexes of these bits is denoted as A. Other bits are set as fixed values predetermined on a receive end and a transmit end and are referred to as a fixed bit set or a frozen bit (frozen bits) set, and a set of indexes of the frozen bit set is denoted as a complementary set A c< of A. The coding process of the polar code is equivalent to x 1 N = μ A F N A ⊕ μ A c F N A C . Herein, F N (A) is a submatrix, in F N , derived from rows corresponding to the indexes in the set A. F N (A C< ) is a submatrix, in F N , derived from rows corresponding to the indexes in the set A C< . u A is a set of information bits in u 1 N , and a quantity of the information bits is K. u AC is a set of fixed bits in u 1 N , a quantity of the fixed bits is (N-K), and the fixed bits are known bits. These fixed bits are generally set to 0. However, the fixed bits may be set to any value provided that the receive end and the transmit end pre-agree on the value. Therefore, coding output of the polar code may be simplified as: x 1 N = μ A ⋅ F N A . Herein, u A is the set of information bits in u 1 N , u A is a row vector with a length of K, that is, |A| = K, a symbol | | represents a quantity of elements in a set, K is a size of an information block, F N (A) is the submatrix that is in the matrix F N and that is derived from the rows corresponding to the indexes in the set A, and F N (A) is an N × N matrix. A construction process of the polar code is a selection process of the set A. This determines performance of the polar code.

[0073] The technical solution in the embodiments of this application is applicable to a scenario in which a terminal device reports a channel quality indicator (CQI) to a network device, to improve data transmission reliability. The following uses a URLLC scenario in a new radio (new radio, NR) technology in 5G as an example to describe a process of a data sending method in the embodiments of this application.

[0074] FIG. 2 is a schematic interaction diagram of a data sending method 200 according to an embodiment of this application. It should be understood that steps 210 to 260 are merely intended to illustrate a process of the data sending method 200, and should not constitute any limitation on the method 200. These steps may also be split into more steps or merged into fewer steps.

[0075] 210. A terminal device obtains a modulation order, a code rate, or spectral efficiency, and selects an index of a reference CQI from a prestored mapping table based on the obtained modulation order, code rate, or spectral efficiency.

[0076] The modulation order, the code rate, or the spectral efficiency that is obtained by the terminal device can reflect current channel quality. Channel quality may be quantified as and represented by a channel quality indicator (Channel Quality Indicator, CQI) index.

[0077] The mapping table in this specification may also be referred to as a CQI table or a modulation and coding scheme (modulation and coding scheme, MCS) table. The mapping table includes a mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency.

[0078] The modulation order determines a quantity of bits transmitted in one symbol. For example, QPSK corresponds to a modulation order 2, 16QAM corresponds to a modulation order 4, and 64QAM corresponds to a modulation order 6.

[0079] The code rate is a ratio of a quantity of information bits in a transport block to a total quantity of bits on a physical channel.

[0080] The spectral efficiency represents information bits that can be carried in one resource element (resource element, RE).

[0081] It may be understood that before sending downlink data, a network device does not know a data channel condition. To improve data transmission reliability, the terminal device may measure channel quality and feed back the channel quality to the network device. The channel quality is quantified as a sequence of 0 to 15 in communication protocols and is defined as a CQI. Each CQI corresponds to one index (referred to as a CQI index below). A CQI that the terminal device feeds back to the network device is only used as a reference. Therefore, an index of the CQI that the terminal device feeds back to the network device is referred to as an index of a reference CQI in this specification.

[0082] 220. The terminal device sends first indication information to a network device, and the network device receives the first indication information from the terminal device, where the first indication information is used to indicate the index of the reference CQI.

[0083] A form of the first indication information is not limited in this specification, and a person skilled in the art can easily figure out a plurality of feasible manners in which the terminal device reports the index of the reference CQI to the network device. For example, the terminal device may indicate the index of the reference CQI to the network device by using 4 bits.

[0084] 230. The network device determines a modulation order, a code rate, or spectral efficiency that actually needs to be used to send data.

[0085] In step 230, the network device may determine, based on a network resource status, the modulation order, the code rate, or the spectral efficiency that actually needs to be used to send data. Alternatively, the network device may determine, from a mapping table with reference to the index, of the reference CQI, reported by the terminal device, a modulation order, a code rate, or spectral efficiency that is corresponding to the reference CQI. In this way, the network device can learn of the current channel quality, to determine the modulation order, the code rate, or the spectral efficiency that actually needs to be used to send data.

[0086] 240. The network device selects an index of a target CQI from a prestored mapping table based on the modulation order, the code rate, or the spectral efficiency that actually needs to be used to send data.

[0087] Similarly, the mapping table includes the mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency.

[0088] 250. The network device sends second indication information to the terminal device, and the terminal device receives the second indication information from the network device.

[0089] The second indication information indicates the index of the target CQI.

[0090] 260. The terminal device determines, from the mapping table based on the index of the target CQI, at least one of a modulation order, a code rate, and a coding scheme that are corresponding to the index of the target CQI. Subsequently, the terminal device processes received data based on the determined modulation order, code rate, and / or coding scheme.

[0091] It may be understood that the target CQI may be the same as or different from the reference CQI. The network device may determine, based on a current network resource status, the modulation order, the code rate, or the spectral efficiency that actually needs to be used to send data, to select, from the mapping table, the index of the target CQI corresponding to the modulation order, the code rate, or the spectral efficiency that actually needs to be used. Alternatively, the network device may select the index of the target CQI with reference to a current network resource status and the index of the reference CQI. Finally, the network device notifies the terminal device of the selected index of the target CQI by using the second indication information. According to the method in this embodiment of this application, before sending data, the network device makes reference to the current channel quality, so that data transmission reliability can be improved.

[0092] Actually, the mapping table is applied to uplink data sending according to a similar principle, except that the terminal device does not need to feed back an index of a reference CQI. The network device may directly determine, based on an uplink channel, at least one of a modulation order, a code rate, and a coding scheme that are used in uplink, determine, according to the mapping table, an index of a target CQI for uplink data sending, and send the index to the terminal device by using indication information. The terminal device may determine, based on the received index of the target CQI and the mapping table, a modulation order, a code rate, or a coding scheme that is corresponding to the received index of the target CQI, and process to-be-sent uplink data based on the determined modulation order, code rate, and / or coding scheme.

[0093] Currently, as a next-generation wireless communication technology, 5G has gained extensive attention and is widely researched by the 3GPP and other international organizations for standardization. 5G can meet a customization requirement of an operator on various industries, vertical industries, and virtual operation services. Three application scenarios of 5G include enhanced mobile broadband (Enhanced Mobile BroadBand, eMBB), ultra-reliable and low latency communications (Ultra-reliable low latency communications, URLLC), and massive machine type communications (Massive Machine type communications, mMTC). A target BLER in the URLLC scenario is accepted to be less than 10%, and needs to be at least 10 -5< or even lower. Considering that the URLLC scenario includes a plurality of different use cases (use case), BLER requirements in different use cases are different and have a relatively large span. It is not proper to design only one CQI table. For example, if a same CQI table is used for data transmission in a plurality of use cases, BLERs may be unable to be ensured in some use cases, while BLERs are excessively strict and are not necessary in some use cases.

[0094] For this, further, this application proposes a CQI table design scheme, to design a CQI table that meets different BLER requirements. In use cases with different BLER requirements, the data transmission reliability can be ensured to some extent.

[0095] The following describes in detail CQI tables designed in this application.

[0096] BLERs required in different use cases are referred to as target BLERs below. In view of a plurality of feasible forms of CQI tables provided in this specification, for clarity, the CQI tables are described one by one based on coding schemes in the CQI tables. In each coding scheme, some forms of CQI tables are provided depending on a target BLER and limitations of a system on a code rate.

[0097] The coding schemes in the CQI tables provided in the following include: Polar, LDPC BG1, and LDPC BG2. As is known from the descriptions above, the BG1 and the BG2 represent two different base graphs. Therefore, the LDPC BG1 represents LDPC obtained based on the base graph BG1. The LDPC BG2 represents LDPC obtained based on the base graph BG2. For description of the BG1 and the BG2, refer to the document 3GPP TS 38.212.V15.0.0 (2017-12).

[0098] The limitations of the system on the code rate below include: no limitation on a code rate, limitation on a minimum code rate without limitation on a maximum code rate, limitation on a highest code rate without limitation on a lowest code rate, limitations on both a lowest code rate and a highest code rate.

[0099] The following provides the CQI tables designed in this application.

[0100] For brevity, the CQI index is denoted as an index below. SE represents spectral efficiency, CR represents a code rate, Mod represents a modulation scheme (namely, a modulation order), and Code represents a used coding scheme.

[0101] It should be noted that a CR in each table in this specification is not an actual code rate, and an actual code rate should be a value of a CR in the table divided by 1024. This is also common practice in the industry. 1. A coding scheme relates to only the polar code. 1.1 No limitation on a code rate.1.1.1 Target BLER=10 -1<

[0103] Table 1 is used to provide an example of selecting a CQI index based on SE and a CR. This is applicable to all tables in this specification. For example, SE=0.07 is obtained based on channel quality or by using another calculation method, and then a CQI index corresponding to an SE value that is less than or equal to 0.07 and that is closest to 0.07 is selected from Table 1, that is, the corresponding CQI index is 1. For another example, CR=60 is obtained based on channel quality or by using another calculation method, and then a CQI index corresponding to a CR value that is less than or equal to 60 and that is closest to 60 is selected from Table 1, that is, the corresponding CQI index is 2. In this embodiment of this application, the terminal device selects the index of the reference CQI according to this rule, or the network device selects the index of the target CQI according to this rule.1.1.2 Target BLER=10 -2<

[0152] 3. A coding scheme includes the LDPC BG2 and the LDPC BG1.

[0153] This section may allow some adjustments to a given mapping table for engineering use, for example, the LDPC BG2 is used for quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) and 16QAM (quadrature amplitude modulation, Quadrature Amplitude Modulation), and the LDPC BG1 is used for 64QAM. In other words, an idea of adjusting the mapping table is to correspond a value of the modulation order to the coding scheme, or to map the modulation order to the coding scheme.3.1 No limitation on a code rate3.1.1 Target BLER=10 -1<

[0202] 4. A coding scheme includes the LDPC BG2 and the polar code.

[0203] This section may also allow some adjustments to a mapping table for engineering use, for example, the polar code is used for QPSK, and the LDPC BG2 is used for 16QAM and 64QAM. In other words, an idea of adjusting the mapping table is to map a value of the modulation order to the coding scheme.4.1 No limitation on a code rate4.1.1 Target BLER=10 -1<

[0304] The foregoing describes in detail the CQI tables provided in this application. The following provides another design idea of the CQI table.

[0305] To reduce design complexity of CQI tables in the URLLC scenario, CQI tables in an eMBB scenario may be reused as many as possible.

[0306] Specifically, because the URLLC scenario requires higher data transmission reliability, in this embodiment of this application, N entries with highest CQI indexes (referred to as an index below) in the CQI tables in the eMBB scenario are deleted, and N entries with lower code rates are added between entries index=0 and index = 1. The following provides possible designs of a CQI table in three scenarios with N = 1, 2, and 3. (1) Target BLER=10 -1<

[0320] The following provides another design idea of the CQI table. A CQI table corresponding to another target BLER is generated by using a signal-to-noise ratio point the same as that of the target BLER=10 -5< .

[0322] The following provides another design idea of the CQI table. Considering that a highest code rate in a CQI table in the eMBB scenario in the 5G standard is 948, a highest code rate of a CQI table used in the URLLC scenario may be limited to 948, and considering that different target BLERs correspond to a same signal-to-noise ratio range of CQI tables, a corresponding CQI table is generated. By using examples in which only the LDPC BG2 is used for channel coding and both the polar code code and the LDPC BG2 are used for channel coding, the following provides possible CQI table designs when the target BLER is 10 -3< and 10 -5< . (1) The LDPC BG2 is used for channel coding.

[0328] Any mapping relationship between a CQI index and spectral efficiency, a code rate, or a coding scheme in the mapping tables shown above may meet all mapping relationships shown in a table above, or may meet only some mapping relationships in a table. For example, a mapping relationship between a CQI index in the first column and parameters in other columns of a mapping table may only meet a mapping relationship shown in a row or mapping relationships in several rows, or may meet a mapping relationship shown in each row in the entire table. For another example, from a row of a table above, there may be the mapping relationship shown in the table between a CQI index and only one column or several columns in the row. This is not limited in this embodiment of this application.

[0329] The foregoing describes in detail the data sending method in this embodiment of this application. According to the data sending method provided in this embodiment of this application, data transmission reliability can be improved.

[0330] Further, the plurality of mapping tables (or referred to as CQI tables) in this embodiment of this application may meet different reliability requirements. A simple and feasible solution is provided for use cases with different BLER requirements, for example, may be applied to different use cases in the URLLC scenario in the NR.

[0331] The following describes a data sending apparatus in the embodiments of this application with reference to FIG. 3 to FIG. 6.

[0332] FIG. 3 is a schematic block diagram of a data sending apparatus 300 according to an embodiment of this application. The apparatus 300 mainly includes a processing unit 310 and a transceiver unit 320.

[0333] The processing unit 310 is configured to obtain a modulation order, a code rate, or spectral efficiency, and select an index of a reference channel quality indicator (CQI) from a prestored mapping table based on the obtained modulation order, code rate, or spectral efficiency, where the mapping table includes a mapping relationship between a CQI index and a modulation order, a code rate, or spectral efficiency.

[0334] The transceiver unit 320 is configured to send first indication information to a network device, where the first indication information is used to indicate the index of the reference CQI.
