Description

[Technical field]

[0001] The present invention relates to communication coding techniques, but is not limited thereto, and more particularly to a method and apparatus for implementing code block partitioning. [Background technology]

[0002] Fig. 1 is a structural block diagram of a digital communication system in the related art. As shown in Fig. 1, the digital communication system includes a transmitting side and a receiving side, and the transmitting side and the receiving side communicate with each other through a channel. In general, the transmitting side mainly includes an information source, a source encoder, a channel encoder and a modulator, and the receiving side mainly includes a demodulator, a channel decoder, a source decoder and a sink. The channel encoder mainly functions to introduce redundant information into information bits according to a certain rule, so that the channel decoder of the receiving side can correct errors that occur when information is transmitted through the channel to a certain extent.

[0003] Baseband processing plays an important role in wireless Internet technology, and the baseband processing up to physical channel mapping is mainly to process the channel coding chain in the channel encoder. Figure 2 is a flow chart of the processing of the channel coding chain in the related art. As shown in Figure 2, the processing of the channel coding chain performs the division of the code block of the input transport block, that is, the transport block entered into the channel encoder is divided into coding blocks according to the size of the largest coding block, and the transport block is the basic input of the channel coding chain, and generally, the data of one transport block has roughly the same coding and modulation method. Then, the obtained multiple coding blocks are subjected to operations such as cyclic redundancy check code (simply referred to as CRC), channel coding, rate matching, modulation, physical channel mapping, etc.

[0004] FIG. 3 is a diagram showing the division of code blocks in the related art. As shown in FIG. 3, when encoding by a channel encoder, information bits of a transport block are divided into coding blocks of a certain length and then coded. In FIG. 3, the transport block is divided into three code blocks, namely, code block 1, code block 2, and code block 3. In general, the larger the coding block, the better the error correction performance. On the other hand, as the code block becomes larger, the complexity of encoding / decoding increases and the decoding delay time increases. Therefore, when designing a channel encoder, it is necessary to limit the size of the largest code block, that is, to set the maximum value of the largest code block. In channel coding, the size of the largest code block allowed is restricted, and one transport block cannot be channel coded unless it is divided into multiple code blocks. Currently, in the process of dividing a transport block into multiple code blocks (i.e., a code block division technique), one transport block needs to be divided into multiple code blocks of approximately the same size. For example, in the Long Term Evolution (LTE) and LTE-A systems of the Third Generation Partnership Project (3GPP), the division of code blocks is in units of 6144 bits, and if the length of a transport block (including a CRC) exceeds 6144 bits, one transport block is divided into multiple code blocks. In addition, the lengths of the coding blocks and the CRC must be within the range of the code length supported by a Turbo channel encoder, and code blocks outside the range of the code length supported by the channel encoder cannot be directly encoded, so stuff bits must be added to these code blocks.

[0005] LTE and LTE-A systems are based on Orthogonal Frequency Division Multiplexing (OFDM), and in the OFDM system, a physical time-frequency resource block (RB), abbreviated as resource block, is a time-frequency two-dimensional unit consisting of a plurality of OFDM symbols that are consecutive in time and a plurality of subcarriers that are consecutive in frequency. FIG. 4 is a diagram showing a resource block whose time length is one time slot in the OFDM system, and as shown in FIG. 4, one resource block occupies 12 subcarriers in the frequency domain. In LTE and LTE-A, the basic time granularity for resource allocation is an integer multiple of one subframe, and the frequency domain granularity is an integer multiple of one RB (i.e., 12 subcarriers). In the RB structure in FIG. 4, one time slot includes 7 consecutive OFDM symbols, and one subframe includes 2 time slots, i.e., 14 consecutive OFDM symbols. Also, each small rectangle in FIG. 4 represents one resource element (RE), and there are 12*7=84 REs on one RB in one time slot. When the length of each time slot is 0.5 ms, two consecutive time slots constitute one subframe, so the length of each subframe is 1 ms. Since one transport block occupies at least one subframe in the time domain, one transport block occupies multiple OFDM symbols in the time domain. Considering that a control channel (e.g., a PDCC channel) also occupies some OFDM symbols, the number of OFDM symbols actually occupied by one transport block is less than 14, but usually exceeds 10.

[0006] FIG. 5 is a diagram showing a physical channel mapping method in an LTE system of the related art. As shown in FIG. 5, in an OFDM system, information transmission is usually in units of one transport block (transfer block, simply TB), one TB usually includes one or more code blocks, each of which generates one coded code block after being coded and rate matched, and each of which generates one symbol stream after being modulated, that is, one transport block can correspond to multiple symbol streams: J1, J2,..., Jn. In LTE and LTE-A, one transport block occupies at most four layers, and each layer occupies the same time-frequency resource area. The transport layer is the concept of a multi-antenna "layer" in LTE and LTE-A, which indicates the number of effective independent channels in spatial multiplexing, and "layer" represents a dimension other than time and frequency.

[0007] In LTE and LTE-A, nine different transmission modes are defined for data transmission, and the different transmission modes correspond to transmission by single antenna transmission, antenna diversity, beamforming, spatial multiplexing, etc., respectively, and in different transmission modes, the transmitter uses different transmission policies and parameters. Downlink control information format (DCI format) is a command word related to the transmission mode. DCI includes signaling related to downlink scheduling assignment and uplink scheduling request, physical channel resource allocation information, transmission format (e.g., rate, modulation order, etc.), spatial multiplexing (e.g., precoding matrix, number of spatial layers, etc.), information on hybrid automatic repeat request (HARQ), and information on power control. DCI is generally transmitted on the downlink physical control channel (PDCCH).

[0008] In LTE, Radio Network Temporary Identifiers (RNTIs) are divided into multiple types of RNTIs according to their functions, and each UE can simultaneously support multiple RNTIs. By scrambling PDCCH control messages with RNTIs, functions such as system broadcasting and specific user scheduling can be realized.

[0009] Block coding is an inter-data packet coding technique, that is, a process of coding a plurality of source data packets to generate a check data packet. Block coding is a process of generating a check sequence at a corresponding position in a check data packet from an information sequence at a corresponding position in the source data packet. Each check data packet contains data at a corresponding position in each check sequence. There are various methods of block coding, for example, the check data packet can be generated by performing an XOR operation, a Reed-Solomon code, a Fountain code, or a network code on each source data packet, and block coding increases the coding constraint between each data packet, thereby providing better transmission performance.

[0010] Code block division is an essential process in the channel coding chain processing process. However, in the application of code block division, delay time is not sufficiently considered. Similarly, take the code block division method of 3GPP LTE as an example. After code block division, the length of each code block is generally 3000 to 6120 bits. When the bandwidth is small, each code block occupies multiple consecutive OFDM symbols in the time domain. The receiving side cannot decode the code block unless it receives all of these OFDM symbols. If the system is sensitive to delay time (e.g., Internet of Vehicles), decoding the data after code block division tends to generate delay time that is unacceptable to the system. Therefore, the code block division technology of the related art will interfere with the operation of a system with high delay time requirements.

[0143] In this embodiment, B is (K max -L), and the number of code blocks C is JPEG0007631453000093.jpg34128 It can be shown by however, JPEG0007631453000094.jpg23128 indicates that x should be rounded up.

[0144] Then, the set of information block lengths supported by the encoder is {K} interleaver Based on this, the information block length of each code block is determined.

[0145] The size of the transport block B is (K max-L) or the number of code blocks C cannot be completely divided, and the coding blocks of coding block C are divided into a first type code block and a second type code block having different code block information block lengths.

II This code block is a type II code block, and then C I This code block is a Type I code block.

[0151] 9 is a diagram showing the division of code blocks according to the second embodiment of the present invention, and the coding block in the left-hand shaded box in the figure is a type II code block. In this embodiment, the number of OFDM symbols each code block occupies in the time domain is limited to achieve the purpose of controlling the delay time. At the same time, the code block division method provided in this embodiment is adapted to the situation where the length of the transport block cannot be completely divided by the number of code blocks.

[0152] Example 3 This embodiment defines the maximum number of OFDM symbols that all coding blocks are allowed to occupy in the time domain, N cb This embodiment differs from the first and second embodiments in that the transmission mode is specified by a transmission mode instruction.

[0153] For example, for a system, new transmission modes A, B, and C are defined, which respectively indicate transmission modes in three scenarios with different delay time requirements. When transmission mode A is used, the delay time requirement is the highest, and the number of OFDM symbols occupied by a single code block cannot exceed one. When transmission mode B is used, the delay time requirement is the second highest, and the number of OFDM symbols occupied by a single code block cannot exceed three. When transmission mode C is used, the delay time requirement is the lowest, and the number of OFDM symbols occupied by a single code block cannot exceed 14.

[0154] The base station semi-statically configures transmission mode A, B or C through higher layer signaling, that is, the transmission mode indication implicitly indicates the maximum number of OFDM symbols that a single code block can occupy.

[0155] Example 4 Compared with the third embodiment, the maximum information block length K max is dictated by the transmission mode.

[0156] Example 5 This embodiment defines the maximum number of OFDM symbols that all code blocks are allowed to occupy in the time domain, N cb This embodiment differs from the third embodiment in that the above is indicated by the downlink control information format (DCI format).

[0157] For example, DCI formats X, Y, and Z are defined for a system, each of which indicates a transmission mode in three different cases with different delay time requirements. When DCI format X is used, the delay time requirement is the highest and the number of OFDM symbols occupied by a single code block cannot exceed one. When DCI format Y is used, the delay time requirement is the second highest and the number of OFDM symbols occupied by a single code block cannot exceed three. When DCI format Z is used, the delay time requirement is the lowest and the number of OFDM symbols occupied by a single code block cannot exceed 14.

[0158] The DCI format can be transmitted from the base station to the relay station or the terminal, or from the relay station to the terminal, on a physical downlink control channel.

[0159] Example 6 In this embodiment, the maximum information block length K of the code block is max This embodiment differs from the fifth embodiment in that the above is indicated by the downlink control information format (DCI format).

[0160] Example 7 This embodiment defines the maximum number of OFDM symbols that all code blocks are allowed to occupy in the time domain, N cb is implicitly indicated by the Radio Network Temporary Identifier (RNTI).

[0161] For example, for a system, RNTIs 1, 2, and 3 are defined to indicate transmission modes in three scenarios with different delay time requirements. When RNTI 1 is used, the delay time requirement is the highest and the number of OFDM symbols occupied by a single code block cannot exceed one. When RNTI 2 is used, the delay time requirement is the second highest and the number of OFDM symbols occupied by a single code block cannot exceed three. When RNTI 3 is used, the delay time requirement is the lowest and the number of OFDM symbols occupied by a single code block cannot exceed 14.

[0162] The RNTI is assigned from the base station to a relay station or a terminal, or from the relay station to a terminal, and can scramble the physical downlink control channel.

[0163] Example 8 In this embodiment, the maximum information block length K of the code block is max This embodiment differs from the seventh embodiment in that the UE number is indicated by a radio network temporary identifier (RNTI).

[0164] Example 9 In this embodiment, a parameter UE Category that can indicate a buffer size of a terminal, a number N of OFDM symbols in the time domain occupied by a transport block, tb , the maximum number of OFDM symbols that all coding blocks are allowed to occupy in the time domain, N cb , and the maximum information block length K of the coding block based on the coding rate R. max This embodiment differs from the first and second embodiments in that:

[0165] Optionally, the maximum number of soft bits N that can be occupied by one transport block can be determined based on the UE Category parameter that can indicate the buffer size of the terminal. Softbits and the number of OFDM symbols in the time domain occupied by the transport block, N tb , the maximum number of OFDM symbols that all coding blocks are allowed to occupy in the time domain, N cb Based on the above, the minimum number of code blocks included in a transport block is JPEG0007631453000099.jpg31128 Then, based on the coding rate R, the reference information block length of the code block is obtained. JPEG0007631453000100.jpg39128 may be determined.

[0166] If the coding method is a convolutional code, K max =K R become.

[0167] If the encoding method is Turbo coding, the maximum information block length K supported by the encoder is encoder , the set of information block lengths supported by the encoder {K} interleaver Based on this, the maximum information block length K max Determine.

[0168] If the transport block coding method is a convolutional code, the maximum information block length K max but, JPEG0007631453000101.jpg21148 is determined as:

[0169] If the transport block coding method is Turbo coding, the maximum information block length K max but, JPEG0007631453000102.jpg32170 is determined as:
