Method and device for transmitting control information in wireless communication system

The invention relates to a wireless communication system. More specifically, the present invention relates to a method and apparatus for transmitting control information in a wireless communication system.

In a mobile communication system, a user equipment can receive information from a base station via a downlink and can transmit information via an uplink. The information received or transmitted by the user device contains information and various control information. And there are various physical channels depending on the type and purpose of the information received or transmitted by the user device.

Figure 1 illustrates a Third Generation Partnership Project (3 ^rd Generation Partnership; 3GPP) Long Term Evolution (Long Term Evolution; LTE) physical channel system, 3GPP LTE system as a mobile communication system and the use of this system An example of a general signal transmission method.

When the power of the user device is turned off and subsequently turned on, or when the user device just enters (or accesses) a new cell service cell, the user device performs an initial cell service area search procedure, such as in steps S101 synchronizes itself with the base station. In this regard, the user equipment can receive a P-SCH (Primary Synchronization Channel) and an S-SCH (Secondary Synchronization Channel) from the base station to maintain synchronization with the base station, and the user equipment also Information such as a cell service area identifier (cell ID) can be acquired. Thereafter, the user equipment can receive a physical broadcast channel (Physical Broadcast Channel) to obtain broadcast information in the cell service area. At the same time, in the initial cell service area search step, the user equipment can receive a downlink reference signal (DL RS) to verify the downlink channel status.

In step S102, the user equipment that has completed the initial cell service area search may receive a physical downlink control channel (PDCCH), and receive a physical downlink shared channel (PDSCH) based on the PDCCH information to obtain more Detailed system information.

Meanwhile, the user equipment that has not completed the initial cell service area search may perform a random access procedure, such as steps S103 and S106 in the later procedure, to complete access to the base station. To this end, the user equipment transmits the feature sequence as a preamble (S103) via a physical random access channel (PRACH), and then the user equipment can receive the PDCCH and its respective PDSCH. The response message is different from the random access (S104). In the case of contention based random access (but excluding handover), the user equipment may perform Contention Resolution Procedures, such as transmitting additional PRACH (S105), and receiving the PDCCH and the PDSCH corresponding to the PDCCH. .

After performing the above procedure, the user equipment can receive the PDCCH/PDSCH (S107) as a general uplink/downlink signal transmission procedure, and then can implement a Physical Uplink Shared Channel (PUSCH). / Physical Uplink Control Channel (PUCCH) transmission (S108).

Figure 2 illustrates a signal processing procedure performed by the user equipment to transmit an uplink signal.

In order to transmit the uplink signal, the user equipment's shuffling module 201 can scramble the transmission signal by using the user equipment-specific scrambling signal. Subsequently, the scrambled signal is input to the modulation mapper 202 to use a Binary Phase Shift Keying (BPSK) scheme, quadrature phase shift keying (Quadrature Phase) based on the transmission signal type and/or channel state. The Shift Keying; QPSK scheme, or the 16 Quadrature Amplitude Modulation (16QAM) scheme, modulates the scrambled signal to a complex symbol. Thereafter, the modulated complex symbols are processed by the conversion precoder 203 and then input to the resource unit mapper 204. Here, the resource unit mapper can map the complex symbols to time-frequency resource units, which will be used in the actual transmission. The processed signal can then be transmitted to the base station via the antenna via a Single-Carrier Frequency-Division Multiple Access (SC-FDMA) signal generator 205.

Figure 3 illustrates a signal processing procedure performed by the base station to transmit downlink signals.

In a 3GPP LTE system, a base station can transmit one or more code words. Therefore, each of the one or more words can be processed into a complex symbol by the scrambling module 301 and the modulation mapper 302 as described above for the uplink procedure of FIG. Subsequently, each of the complex symbols can be mapped by the layer mapper 303 to the complex layer, and each layer can be multiplied by a precoding module 304 to a predetermined precoding matrix selected based on the channel state, thereby assigning each layer to each A transmitting antenna. Each signal of the processed transmission signal, which is separate from an antenna, is mapped to the time-frequency resource unit by a respective resource unit mapper 305, which will be used in the actual transmission. Thereafter, each processed transmission signal is transmitted through an Orthogonal Frequency Division Multiple Access (OFDMA) signal generator 306 for transmission via each antenna.

In the mobile communication system, the Peak-to-Average Ratio (PAPR) when the user equipment transmits signals via the uplink can be more disadvantageous than the base station transmitting via the downlink. Therefore, as described above with respect to FIGS. 2 and 3, unlike the OFDMA scheme used in downlink signal transmission, the SC-FDMA scheme is used in uplink signal transmission.

Figure 4 illustrates an SC-FDMA scheme for transmitting uplink signals in a mobile communication system, and an OFDMA scheme for transmitting downlink signals.

Here, the user equipment for uplink signal transmission has some similarities with the base station for downlink signal transmission: each user equipment and base station includes a sequence to parallel converter 401, subcarriers ( The subcarrier mapper 403, the M-point inverse Fourier transform (M-point IDFT) module 404, and the Cyclic Prefix (CP) are added to the module 406.

However, the user equipment transmitting the signal by using the SC-FDMA scheme additionally includes a parallel to sequence converter 405 and an N point IDFT module 402. Moreover, the N-point IDFT module 402 is configured to eliminate a predetermined portion of the IDFT processing effect generated by the M-point IDFT module such that the transmitted signal can have a single carrier nature. Figure 5 illustrates a time domain signal mapping method for satisfying single carrier characteristics in the frequency domain. In Fig. 5, (a) represents a localized mapping method, and (b) represents a distributed mapping method. The positioning mapping method has been defined in the current 3GPP LTE system.

At the same time, a clustered SC-FDMA will now be described which corresponds to a calibrated form of SC-FDMA. Among the sequential subcarrier mapping procedures between the DFT program and the fast inverse Fourier transform (IFFT) program, the clustered SC-FDMA divides the DFT program output samples into subgroups so that the IFFT sampling input unit can The subgroups are mapped to subcarrier regions, and the subcarrier regions are spaced apart from each other. And in some cases, the clustered SC-FDMA may include a filter and a loop extension. At this time, the subgroup can be called a cluster, and the cyclic extension can involve the process of interpolating the guard interval between the consecutive (or connected) symbols, and the guard interval is longer than the maximum delay of the channel. Frequency to prevent inter-symbol interference (ISI) from being generated while transmitting each sub-carrier symbol via a multi-path channel.

Accordingly, the present invention is directed to a method and apparatus for transmitting control information in a wireless communication system in a wireless communication system that substantially obviates one or more problems due to limitations and disadvantages of the prior art.

In order to achieve these and other advantages in accordance with the purpose of the present invention, a method for transmitting information in a wireless communication system by using a Reed-Muller (RM) coding scheme is widely practiced and widely described herein. The method for transmitting the information material includes the following steps: if the one-dimensional size O of the information material is greater than or equal to a predetermined quantity, the information material is divided into the first information material and the second information material; and the RM code is applied to Each of the first information material and the second information material; concatenating the encoded first information material and the encoded second information material; and transmitting the serialized information material.

In addition, the transmitting module can transmit the serialized first information material and the second information material by using the predetermined number of Q ′ resource units.

Here, the predetermined number may correspond to 12 bits, and wherein each bit size of the encoded first information material and the encoded second information material corresponds to 32 bits. In addition, the information material may correspond to Uplink Control Information (UCI), and the uplink control information may be transmitted via a physical uplink shared channel (PUSCH). And preferably, the uplink control information may include a Hybrid Automatic Retransmission reQuest (HARQ)-Acknowledgment/Negative Acknowledgment (ACK/NACK) data or a level indication ( Rank Indicator; RI).

More specifically, it is preferable that a size O ₁ of the first information material corresponds to a bit, and wherein a size O _{2 of} the second information material corresponds to Bit. Each Further, the number of resource units in Q 'is an even number, the number of the first resource _{units. 1} Q' and Q number of the second resource unit ₂ 'may correspond to . Moreover, when the number of resource units Q ' is an odd number, the first resource unit number Q ₁ ' may correspond to ( Q '+1)/2, and the second resource unit number Q ₂ ' may correspond to ( Q '-1)/2.

It is to be understood that both the foregoing general description of the invention,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments embodiments The embodiments of the present invention are provided to assist in understanding the configuration, the operation, and other features of the present invention, and the description of the exemplary embodiments of the present invention. The specific embodiments of the present invention described below correspond to an exemplary system to which the technical features of the present invention are applied. For the sake of simplicity, the present invention will be described with the IEEE 802.16 system as an example of the present invention. However, this is merely exemplary, and thus the present invention is applicable to various wireless communication systems included in the 3rd Generation Partnership Project (3GPP).

The invention is described below using specific terms to assist in understanding the invention. Therefore, the use of such specific terms may also be varied in different forms without departing from the spirit and scope of the invention.

Figure 6 illustrates a signal processing procedure in accordance with an embodiment of the present invention in which DFT program output samples are mapped to a single carrier in a clustered SC-FDMA. In addition, Figures 7 and 8 each illustrate a signal processing procedure in accordance with an embodiment of the present invention in which DFT program output samples are mapped to a multi-carrier in a clustered SC-FDMA.

Here, FIG. 6 corresponds to an example in which an application cluster SC-FDMA is applied to an intra-carrier. 7 and 8 correspond to an example of applying clustered SC-FDMA to an inter-carrier. Further, Fig. 7 represents a case where a signal is generated (or manufactured) via a single IFFT block when the subcarrier spacing between adjacent component carriers is aligned, while the component carriers are connected in the frequency domain in a connected manner. And Fig. 8 represents a case where signals are generated via a plurality of IFFT blocks because the component carriers are not adjacent to each other, and the component carriers are not allocated in the frequency domain.

Segmented SC-FDMA involves simple implementation of DFT spread spectrum of traditional SC-FDMA according to the one-to-one correspondence between DFT and IFFT when the same number of IFFTs as the number of random DFTs are applied. And extending the frequency subcarrier mapping configuration of the IFFT, where the segmented SC-FDMA is also referred to as NxSC-FDMA or NxDFT-s-OFDMA. In the description of the present invention, this will be collectively referred to as segmented SC-FDMA.

Figure 9 illustrates a signal processing procedure in a segmented SC-FDMA system in accordance with an embodiment of the present invention. As illustrated in FIG. 9, the segmentation SC-FDMA program involves a process of grouping the entire time domain modulation symbols into N groups (where N is an integer greater than 1) and executing the DFT program in group units. To mitigate the single carrier nature state (or specification).

Figure 10 illustrates a signal processing procedure for transmitting a reference signal (hereinafter referred to as RS) via the uplink. As illustrated in Figure 10, the data is generated from the time domain and frequency mapped via a DFT precoder for transmission via IFFT. Conversely, the RS bypasses the DFT precoder and generates directly in the frequency domain (S11), and is transmitted after being sequentially processed by the positioning map (S12) and IFFT (S13) programs, and then cyclically prefixes ( CP) is added to the program (S14).

Figure 11 illustrates a sub-frame structure for transmitting RS for the case of a normal cyclic prefix (CP). And Fig. 12 illustrates the sub-frame structure for transmitting the RS for the case of extending the cyclic prefix (CP). Referring to Fig. 11, the RS is transmitted via the fourth and eleventh OFDM symbols. Referring to Fig. 12, the RS is transmitted via the third and ninth OFDM symbols.

Meanwhile, a processing structure of an uplink shared channel as a transmission channel will now be described below. Figure 13 illustrates a block diagram illustrating the processing procedure for the transmit channel of the uplink shared channel. As shown in Figure 13, the data information of the control information multiplex is added to the TB of the Transport Block (hereinafter referred to as "TB") Cyclic Redundancy Check (CRC). It will be transmitted (130) via the uplink. Then, according to the TB size, the processed transport block is divided into a plurality of code blocks (hereinafter referred to as "CB"s), and the CB-dedicated CRC is added to a plurality of CBs (131). Thereafter, the resulting value is channel encoded (132). The channel encoded data is then rate matched (133) and then combined with CBs (134). Thereafter, the CBs are combined with the Channel Quality Information/Precoding Matrix Index (CQI/PMI) multiplex (135).

At the same time, a channel coding procedure (136) separate from the data encoding procedure is performed on the CQI/PMI. Subsequently, the channel coded CQI/PMI and data multiplex (135).

Furthermore, a channel coding program separated from the data encoding program is also performed on the Rank Indication (RI).

For the case of Acknowledgment/Negative Acknowledgment (ACK/NACK), a channel coding procedure (138) separate from the data, CQI/PMI and RI channel coding procedures is implemented. The multiplexed data is channel interleaved with the CQI/PMI, the separated channel-coded RI, and the ACK/NACK to generate an output signal (139).

Meanwhile, an entity resource unit (hereinafter referred to as "RE" s) for data and control information in the LTE uplink system will be described in detail.

Figure 14 illustrates an entity resource mapping method for uplink data and control channels.

As illustrated in Figure 14, the CQI/PMI and data are mapped onto the RE in a time-first manner. The encoded ACK/NACK is punctured and inserted around the Demodulation Variable Reference Signal (DM RS), and the RI is mapped to the RE located next to the RE with the ACK/NACK inserted therein. Resources for RI and ACK/NACK can occupy up to four SC-FDMA symbols. For the case where the data and control information are simultaneously transmitted to the uplink shared channel, the mapping order may correspond to the sequence of RI, CQI/PMI and data concatenation and ACK/NACK. More specifically, by using the time-first method, the RI is first mapped, then the CQI/PMI and the data are concatenated to the remaining REs, and the RE having the RI mapped thereto is excluded. The ACK/NACK is mapped by puncturing the CQI/PMI mapped to the respective REs in tandem with the data.

As described above, the single carrier property can be satisfied by multiplexing the data with uplink control information (UCI) such as CQI/PMI and the like. Therefore, uplink transmission maintaining a low cubic metric (CM) can be achieved.

In the enhanced system of the legacy system (for example, LTE Rel-10), for each user equipment, among the two transmission methods of SC-FDMA and cluster DFTs OFDMA in each carrier component, the uplink may be Transfer the application at least one transfer method. And the applied transmission method can be applied together with uplink multiple input multiple output (UL-MIMO) transmission.

Figure 15 illustrates a flow chart illustrating a method for efficiently multiplexing data and control channels within an uplink shared channel.

As illustrated in FIG. 15, the user equipment recognizes the level of data different from the physical uplink shared channel (PUSCH) (S150). Subsequently, the user equipment configures the level of the uplink control channel (here, the control channel relates to uplink control information (UCI), such as CQI, ACK/NACK, RI, etc.) to be the same level as the data (S151) ). Further, the user equipment multiplexes the data and the control information (S152). Subsequently, after mapping the data and the CQI by using the time-first method, channel interleaving may be performed to map the RI to the designated RE, and the ACK/NACK is mapped by puncturing the REs around the DM-RS (S153).

Thereafter, the data and control channels can be modulated to QPSK, 16QAM and 64QAM, etc. according to the MCS table (S154). The modulation step can now be moved (or shifted) to another location. (For example, a modulation block can be moved (or shifted) to a position prior to the multiplex step of the data and control channels.) Again, channel interleaving can be performed by word units, or can be performed by hierarchical units.

Figure 16 illustrates a block diagram illustrating a method for generating a transmission signal for a data and control channel.

Assuming two words, channel coding (160) is performed for each word, and rate matching is performed according to a given MCS level and resource size (161). Thereafter, the encoded bit (162) can be scrambled by using a cell service area specific method, a UE specific method, or a code specific method.

Subsequently, the word code is applied to the hierarchical map (163). During this procedure, a job of hierarchical shifting or permutation may be included.

Figure 17 illustrates the word-to-layer mapping method. The word-to-layer mapping can be performed by using the rules illustrated in FIG. The precoding position illustrated in Fig. 17 may be different from the precoding position illustrated in Fig. 13.

Control information such as CQI, RI, and ACK/NACK is channel encoded (165) based on a given specification. At this time, CQI, RI, and ACK/NACK can be encoded by using the same channel coding for all words, or encoding different channels for each word.

Thereafter, a plurality of encoded bits (166) can be varied by a bit size controller. The bit size controller can form a single body (155) with the channel coding block. The signal output from the bit size controller is shuffled (167). At this time, the scramble may be dedicated to the cell service area, dedicated to the layer, dedicated to the code, or dedicated to the UE.

The bit size controller can perform the following operations.

(1) The controller recognizes the data level (n_rank_pusch) that is different from the PUSCH.

(2) The level of the control channel (n_rank_control) is configured to be the same as the level of the data (ie, n_rank_control=n_rank_pusch), and the number of bits separately from the control channel is multiplied by the control channel level, thereby extending the number of bits .

One of the methods for performing the above operations is to simply copy and repeat the control channel. The control channel may now correspond to the information level prior to processing by the channel encoding, or to the encoded bit level after processing by the channel encoding. More specifically, for example, in the case where the control channel [a0, a1, a2, a3] has n_bit_crtl=4, and in the case of n_rank_pusch=2, the number of extension bits (n_ext_crtl) can be changed to 8 bits [a0, a1 , a2, a3, a0, a1, a2, a3].

For the case where the bit size controller and the channel coding unit are configured as a single body, the coded bits can be generated by adopting channel coding and rate matching, and the channel coding and rate matching are defined in a conventional system (for example, , LTE Rel-8).

Furthermore, to further provide randomization for each layer, a bit level interleaving procedure can be implemented in the bit size controller. Alternatively, as an equal method of the above method, an interleaving procedure may be performed at the level of the modulation symbol.

The CQI/PMI channel and data multiplex (164) can be separated by two data codes by means of a data/control multiplexer. Then, by making the ACK/NACK information mapped to the REs around the uplink DM-RS, in each slot of the subframe, the channel interleaver maps the CQI/ according to the time-first mapping method. PMI (168).

Next, modulation is performed on each layer (169), and DFT precoding (170), MIMO precoding (171), RE mapping (172), and the like are sequentially performed. Thereafter, an SC-FDMA signal is generated and transmitted via the antenna (173).

The functional blocks are not limited to the positions illustrated in Fig. 16. And in some cases, the corresponding location can be changed. For example, the shuffling blocks 162 and 167 can be placed after the channel interleaving block. Likewise, the word-to-layer mapping block 163 can be placed after the channel interleave block 168 or after the modulation mapper block 169.

The present invention is directed to a channel coding method for UCI and a corresponding resource allocation and transmission method thereof for transmitting UCI (such as CQI, ACK/NACK, and RI) on a PUSCH. Although the invention is described primarily based on transmissions within a SU-MIMO environment, the invention may also be applied to single antenna transmissions, which may correspond to the particular case of SU-MIMO.

In the case where the UCI and data currently corresponding to SU-MIMO are transmitted on the PUSCH, the transmission can be performed by using the following method. The location of the UCI within the PUSCH will now be described below.

The CQI is in series with the data and is mapped to the remaining REs (excluding REs with RI mappings therein) by a time-first mapping method and the same modulation order and constellation as the data. For the case of SU-MIMO, the CQI is transmitted by spreading the CQI to one word and the word to which the CQI is transferred among the two words corresponds to a word having a higher MCS level. And for the case where two words have the same MCS level, the CQI is transferred to the word code 0. In addition, by interpolating the CQI in series with the data to place the ACK/NACK, the CQI and data series are mapped to symbols located on both sides of the reference signal. And because the reference signal is placed in the third and tenth symbols, by starting at the bottom subcarriers of the second, fourth, ninth, and eleventh symbols and going up , to implement the mapping program. At this time, the ACK/NACK symbols are mapped in the order of the second, eleventh, ninth, and fourth symbols. The RI is mapped to symbols placed next to the ACK/NACK and is mapped earlier than any other information (material, CQI, ACK/NACK) that is transmitted to the PUSCH. More specifically, the mapping of the RI is performed by starting up the subcarriers at the bottom of the first, fifth, eighth, and twelfth symbols. At this time, the RI symbol is mapped by the order of the first, twelfth, eighth, and fifth symbols. Most specifically, when the information bit size is equal to one bit or two bits, ACK/NACK and RI are mapped by using the QPSK method and using only the four corners of the cluster. And when the information bit size is greater than or equal to three bits, ACK/NACK and RI can be mapped by using all clusters of the same modulation order as the modulation order of the data. Furthermore, ACK/NACK uses the same resources as the RI, which corresponds to the same location within each layer to convey the same information.

A method of calculating the number of resource elements for UCI in the PUSCH will now be described below. First, the number of resource elements used for CQI and ACK/NACK (or RI) (which is being transmitted in the PUSCH) can be calculated by Equation 1 and Equation 2 below.

[Equation 1]

[Equation 2]

Here, the number of resource elements for CQI and ACK/NACK (or RI) may also be represented as a number of coded modulation symbols.

The channel coding method for UCI transmitted in the PUSCH will now be described below. First, for CQI, when the payload size is less than or equal to 11 bits, the application uses the RM encoding procedure of Table 1 below to input the sequence (ie, information material) o ₀ , o ₁ , o ₂ ,. .., o _{O -1} to produce a 32-bit output sequence. In addition, for the case where the CQI payload size exceeds 11 bits, the Tail biting convolutional coding (TBCC) method can be applied after the 8-bit CRC is added.

Meanwhile, a channel coding method for ACK/NACK and RI transmitted in the PUSCH will now be described. If the size of the ACK/NACK and RI information is equal to 1 bit (ie, if the input sequence is [ ]), the channel coding procedure is performed according to the modulation order shown in Table 2 below. In addition, if the size of the ACK/NACK and RI information is equal to 2 bits (ie, if the input sequence is [ ]), then the channel coding procedure is performed according to the modulation order shown in Table 3 below. Most specifically, refer to Table 3, Corresponding to the ACK/NACK or RI data for word 0, Corresponds to ACK/NACK or RI data for word 1 Corresponding to ( ) mod2. More specifically, in Tables 2 and 3, x represents a value of 1, and y represents a repetition of a previous value.

Alternatively, when the information size of the ACK/NACK and RI is in the range of 3 to 11 bits, the RM encoding method of the following list 1 can be applied to generate a 32-bit output sequence.

[Table 1]

[Table 2]

[table 3]

Most specifically, for the case where the RM encoding program is performed using Table 1, the output data is represented as b ₀ , b ₁ , b ₂ , b ₃ , ..., b _{B -1} , and B = 32 as shown in the following Equation 3. .

[Equation 3]

Finally, the UCI is encoded into B bits, that is, the ACK/NACK or RI data can be rate matched according to Equation 4 below to be mapped to Q' resource elements, which are calculated according to Equation 1 and Equation 2.

[Equation 4]

q _i = b _{i mod B} , i =0,1,..., Q _m × Q '-1

The associated channel coding method techniques are known under the assumption that a single carrier environment is given. However, for the case where the multi-carrier method is applied, as in the LTE-A system, since the UCI is generally known to correspond to each component carrier, that is, the ACK/NACK or RI data is combined by a component carrier order. The UCI size can also increase in proportion to the number of component carriers. Most specifically, for the case of RI, a conventional single carrier can have a maximum of 3 bits of information. However, in an environment where five component carriers can be aggregated, the maximum information size can be equal to 15 bits. Therefore, because a maximum 11-bit information material can be encoded by using the currently known RM coding scheme, a new scheme (or method) capable of decoding UCI in a multi-carrier environment is needed. An encoding method and rate matching method for each UCI size will now be specifically proposed below.

<First embodiment - when the size of the information material is less than or equal to 11 bits>

In a single carrier environment and a multi-carrier environment, since RM encoding is used, when the RI or ACK/NACK has a size of 3 bits or more, the encoded output data has a bit size of 32 bits. However, for the case where the channel state is very good, and when the number of resource units is calculated by using Equation 1 and Equation 2, only a very small number of resource units can be allocated according to the bit size of the information material. In this case, in the rate matching step (which is performed using Equation 4), the encoded word may be over-punctured due to the RM encoding, thereby causing performance degradation.

More specifically, in order to perform robust transmission without being affected by the channel state, because RI or ACK/NACK transmits the word code (word code is encoded by RI or ACK/NACK by using the RM encoding scheme), by using only the cluster point Instead of using all clusters to perform modulation, it is generally known that only 2 bits are mapped to a single resource unit. Therefore, in order to transmit all the codes encoded to 32 bits, a total of 16 resource elements are required. At this time, if the calculated number of resource units is less than 16, the word code can be punctured as a rate matching program. However, when performing the puncturing procedure, a receiving end can determine the program as an error. Therefore, even if the word has a value of 16 (which corresponds to the maximum value of the minimum distance between the codes of the RM code), the performance cannot be guaranteed when the portion of the data corresponding to the four symbols is punctured. In addition, since the puncturing procedure is performed in a 2-bit unit starting from the last bit of the word, in order to maintain the performance of the puncturing process, the degree of degradation of the performance can be increased. In the following, as a first embodiment of the invention, the invention proposes to prevent such performance degradation caused by the perforation procedure described above.

1) When the ACK/NACK or RI has a size of information material corresponding to a specific number of bits, that is, when the ACK/NACK or RI corresponds to an information material having a size greater than or equal to 3 bits, the present invention A specific embodiment proposes a method for configuring the minimum value to the number of resource elements being allocated to an ACK/NACK or RI. For example, when the information size of the ACK/NACK or RI is greater than or equal to 3 bits, the number of resource units being allocated to transmit the information material of the ACK/NACK or RI is configured to be equal to the minimum number of 16 bits. Here, it is preferable that the minimum value of the number of resource units (which are allocated to ACK/NACK or RI) is greater than or equal to half the number of bits corresponding to the size of the information material. More specifically, the number of REs being allocated to ACK/NACK and RI, that is, the number of coded modulation symbols, can be calculated by Equation 6 and Equation 7 below.

[Equation 5]

[Equation 6]

Being allocated to the ACK / NACK resource units or RI number Q 'of the minimum value _min, 7 can be determined according to the following equation.

[Equation 7]

Here, O represents the size of the information material bit of the ACK/NACK or RI, and Q _m corresponds to the size of each symbol bit according to the modulation order. For the case of QPSK, Q _m is equal to 2, for 16QAM, Q _m is equal to 4, and for 64QAM, Q _m is equal to 6.

Meanwhile, for the case of ACK/NACK and RI, the coding rate standard for the RM encoding procedure is 1/3. Therefore, the minimum value Q ' _{min of the} number of resource units being allocated to ACK/NACK or RI can be determined by Equation 8 to Equation 10 below.

[Equation 8]

[Equation 9]

[Equation 10]

The following Tables 4 to 7 respectively correspond to an example of calculating the minimum value Q ' _min of the number of resource units being allocated to ACK/NACK or RI by using Equations 7 to 10 above.

[Table 4]

[table 5]

[Table 6]

[Table 7]

2) Further, in the first specific embodiment of the present invention, after ACK/NACK or RI is encoded by the RM code, when the ACK/NACK or RI is punctured by the rate matching procedure, it may be considered by a predetermined and specific order. Perform perforation. More specifically, when an ACK/NACK or RI is allocated to a given number of resource elements, the allocation order may be grouped by ACK/NACK or RI into 1-bit, 2-bit or a specific number of bit units. The allocation order is determined such that the ACK/NACK or RI can be assigned to the resource unit by the determined order. For example, if the output data has an encoded ACK/NACK or RI corresponding to c ₀ , c ₁ , . . . , c ₃₁ , the output data can be weighted by the ordering function π( i ), i =0, 1, . . . , 31 Aligning the output data, the ranking function corresponds to a predetermined criterion to exhibit the best performance when performing the puncturing procedure. Then, depending on the order of the order, the resource units can be allocated sequentially, or the puncturing program can be executed sequentially, by indexing the order or by indexing the order. More specifically, when eight encoded output data are allocated to resource elements, the located data becomes c _π(0) , c _π(1) ,..., c _π(7) instead of c ₀ , c ₁ ,..., c ₇ .

3) Furthermore, according to the first embodiment of the present invention, different information types may be used according to the size of the information materials different from ACK/NACK and RI. value. When puncturing the encoded output data (i.e., using the RM encoding scheme generated word), the effect of the puncturing procedure may vary depending on the bit size of the information material. Therefore, depending on the degree of influence affecting the minimum distance of the word caused by the perforation procedure, different configurations can be configured. value. For example, when punching a word, the fastest bit size of the information material is set relatively large. Value so that its minimum distance value is equal to zero.

Although the above procedures 1) to 3) describe a procedure for setting the minimum value of the number of resource units to be allocated to the UCI, in order to achieve the same purpose, the minimum bit size of the encoded output data after rate matching may be set. . More specifically, the minimum value shown in Equation 5 can be configured by the number of resource units as the minimum bit size of the output material, as shown in Equation 11 below.

<Second embodiment - when the size of the information material is equal to or greater than 12 bits>

When the size of the information data of ACK/NACK and RI is equal to or greater than 12 bits, the PUSCH groups the information materials into the same bit size or different bit sizes, which corresponds to at least two data sets. Channel coding can be performed for each group of grouped information data by using a (32, 0) RM coding scheme (which is used in each PUSCH).

More specifically, when UCI (such as RI or ACK/NACK) is multiplexed with data in a multi-carrier environment, UCI information material bits are grouped into at least two groups, and each group can be It is encoded into a single word. In this case, when the size of the information material bit is between 3 bits and 11 bits, if the size of the information data contained in each group is between 6 bits and 10 bits, Then, a (32, 0) RM coding scheme can be applied to each group, that is, a dual RM coding scheme. Hereinafter, a method for grouping information materials will first be described, and a method for calculating the number of resource units for allocating encoded information materials, and for applying dual (32, 0) RM encoding will be described later. A method of performing rate matching (ie, coding chain) at the time of the scheme. Hereinafter, a method for calculating the minimum number of resource units that can be allocated to each word code when applying the dual (32, 0) RM coding scheme according to the first embodiment of the present invention will be described.

1) Information data grouping method when performing double RM encoding

First, a method for grouping information materials having a size of 12 bits or more to apply a dual (32, 0) RM encoding scheme will be described with reference to FIGS. 18 and 19.

(1) Figure 18 illustrates a method for grouping information materials to apply a dual (32, 0) RM encoding scheme in accordance with a second embodiment of the present invention.

Referring to Fig. 18, all (or the entire) information material can be sequentially allocated as input data for each encoder of the dual (32,0) RM encoding scheme. For example, when the 12-bit information material d ₀ , d ₁ , d ₂ , . . . , d ₁₁ is encoded by two RM encoders, the information material being input to the first RM encoder can correspond to 6 bits d _{0 .} , d ₂ , d ₄ ,..., d ₁₀ , which correspond to even information data bits. The information material being input to the second (32, 0) RM encoder may correspond to 6 bits d ₁ , d ₃ , d ₅ , ..., d ₁₁ , which correspond to odd information data bits.

More specifically, for a given information material corresponding to o ₀ , o ₁ , o ₂ , ..., o _{Q -1} , the input data b ₀ , b ₁ , b ₂ ,..., b _Q at the RM encoder _-1 , if b ₀ , b ₁ , b ₂ ,..., versus Each is input to the first RM encoder and the second RM encoder. When i is an even number, then b _{i /2} = o _i . And when i is an odd number, then .

(2) FIG. 19 illustrates another method for grouping information materials to apply a dual (32, 0) RM encoding scheme in accordance with a second embodiment of the present invention.

Referring to Fig. 19, half of all information materials can be assigned as information material being input to the first RM encoder, and the other half of all information materials can be assigned to be input to the second RM encoder. Information materials. For example, when the 12-bit information material d ₀ , d ₁ , d ₂ , ..., d ₁₁ is encoded by two RM encoders, the 6 bits of the information material d ₀ , d ₁ , d ₂ ,... , d ₅ can be input to the first RM encoder, and the 6-bit d ₆ , d ₇ , d ₈ , ..., d _{11 of the} information material can be input to the second RM encoder.

Meanwhile, referring collectively to FIGS. 18 and 19, when the bit size O of all information materials corresponds to an odd number, ( O +1)/2 bits can be assigned to be input to the first RM code. The information of the device, and ( O -1)/2 bits can be assigned as the information material being input to the second RM encoder. Alternatively, ( O -1)/2 bits may be allocated as information material being input to the first RM encoder, and ( O +1)/2 bits may be allocated as being input to the second RM code Information.

(3) Among the component carriers, the information material corresponding to the main component carriers (primary CCs) can be configured as one group, and the information material corresponding to other component carriers (CCs) can be configured as another group. Here, the primary component carrier may correspond to a component carrier having the most significant index or the least significant index, or may correspond to a predetermined index. Alternatively, it may have the most component carrier or may correspond to a predetermined index. Alternatively, the component carrier having the most favorable channel state or having the least favorable channel state may also be configured as the primary component carrier. Furthermore, the component carrier having the information material of the largest or smallest bit size can be configured as the main component carrier. Also, for the coding rate and modulation order, the main component carrier can be configured using the same method.

2) Coding chain when applying dual RM coding scheme

(1) A method for calculating the number of resource elements for allocating encoded information when applying a dual RM coding scheme will now be defined below. In calculating the number of resource units, the present invention proposes a method for calculating the number of resource units by using Equation 1 and Equation 2, which is based on the bit size of all information materials, and not based on information materials that are divided into a plurality of groups. Bit size. More specifically, when ACK/NACK and RI are encoded by using a dual RM coding scheme, the number of resource elements being allocated to each RM word code is equally allocated by the number of resource elements from all information units. O cell size to the location is calculated.

Therefore, when the number of resource units Q ' calculated from the location element size O of all the information materials corresponds to an even number, Q '/2 resource units can be allocated to each word code according to the dual RM coding scheme. Generate each word.

In addition, when the number of resource units Q ' calculated from the location element size O of all the information materials corresponds to an odd number, ( Q '+1)/2 resource units can be allocated to the first word, first The word code is generated according to the dual RM coding scheme, and ( Q '-1)/2 resource units are allocated to the second word code, and the second word code is also generated according to the dual RM coding scheme. Alternatively, ( Q '-1)/2 resource elements may be allocated to the first word, and ( Q '+1)/2 resource elements may be allocated to the second word.

(2) However, in the rate matching step using Equation 4, rate matching (i.e., puncturing) may be performed for each word code, and each word code is generated according to the dual RM coding scheme, and the number of resource units simultaneously Matching the modulation order, where the resource elements are assigned to each word as described in 2).

(3) Figure 20 illustrates an encoding chain for dual RM encoding in accordance with a second embodiment of the present invention.

Referring to Fig. 20, a coding chain for dual RM coding according to the present invention can be generally regarded as a method for implementing a dual RM coding scheme, which is proposed in the present invention, wherein a single resource unit calculation system and each Rate matching program combination.

More specifically, for the case where the information size of ACK/NACK and RI is greater than or equal to 12 bits, the dual (32, 0) RM coding scheme of the present invention can be applied, and as described in 1), all information materials can be They are grouped and divided into the first information and the second information.

Then, as described in (1) or 2), when calculating the number of resource units to be allocated, the number of corresponding resource units can be calculated according to the bit size of all information materials, instead of being divided into a plurality of groups according to The bit size of the information material. Subsequently, the calculated number of resource units is allocated to each RM encoder. The rate output from each encoder can then be rate matched according to the given resource size. Thereafter, the processed data can be serially connected. Furthermore, although an interleaver can be applied to the serial data, the interleaver can be omitted in some cases.

3) Method for determining the minimum number of resource elements when applying a dual RM coding scheme

Meanwhile, as described in the first embodiment of the present invention, in the dual RM coding scheme, a minimum value is also required to be allocated in the number of resource units being allocated to UCI (ie, ACK/NACK or RI). Therefore, in the dual RM coding scheme according to the present invention, the minimum number of resource elements being allocated to ACK/NACK and RI can be configured by adding the minimum number of resource elements corresponding to each packetized information material bit. .

More specifically, if the equation for calculating the minimum number of resource elements (ie, Equations 5 to 7) is for the information of 0 bits (referred to as f ( O ) for simplicity), Calculating the minimum number of equations of resource elements to be assigned to each word during the dual RM encoding procedure may correspond to f ( O /2). And the number of resource units allocated to all (or the entire) ACK/NACK and RI may correspond to f ( O /2)+ f ( O /2). As a simple example, the minimum number of resource elements assigned to a 12-bit size information material corresponds to f (6) + f (6) instead of f (12).

Meanwhile, for the case where the size of the information material corresponds to an odd number, the size of each information data group used for calculating the minimum number of resource units can be allocated by ( O +1)/2 bits for the first word code, and for the first Two words can be assigned by ( O -1)/2 bits. Alternatively, the minimum number of resource elements may be allocated by ( O +1)/2 bits for the first word and by ( O -1)/2 bits for the second word. In this case, the minimum number of resource elements being allocated to all ACK/NACK and RI corresponds to f (( O +1)/2) + f (( O -1)/2). For example, for a 13-bit information, the minimum number of resource units calculated corresponds to f (7) + f (6) instead of f (13).

Therefore, Equation 7 can be changed to Equation 12 and Equation 13 below.

[Equation 12]

(where O is an even number)

[Equation 13]

(where O is an odd number)

The combination of Equation 12 and Equation 13 can be expressed as Equation 14 below.

[Equation 14]

If all information materials are divided into N groups so that the RM encoding scheme can be applied separately, and if the size of the information material being input during each RM encoding process is called O _i , it is being assigned to ACK/ NACK corresponds to the minimum number of resource units of the RI to .

At the same time, among the modulation orders of the transmission block, in which the PUSCH transmission is performed, Q _m can correspond to a lower modulation order. More specifically, when the modulation order of the first transfer block (TB) is QPSK, and when the modulation order of the second TB is 16QAM, Q _m is equal to 2, which corresponds to The lower modulation order of the modulation order of the two transfer blocks. Alternatively, Q _m may correspond to the average value of transport blocks modulation order, wherein the PUSCH transmission line purposes. More specifically, when the modulation order of the first transfer block (TB) is QPSK, and when the modulation order of the second TB is 16QAM, the Q _m system is equal to 3, which corresponds to two The average of the modulation block modulation order. Furthermore, among the modulation orders of the transmission block, in which PUSCH transmission is performed, Q _m can correspond to a higher modulation order. More specifically, when the modulation order of the first transfer block (TB) is QPSK, and when the modulation order of the second TB is 16QAM, the Q _m system is equal to 4, which corresponds to The 16QAM value of the higher modulation order of the modulation order of the two transfer blocks.

<Third Embodiment - Method for Mapping Encoded Information to Resource Units>

When the encoded UCI to PUSCH is mapped according to the first embodiment and the second embodiment of the present invention, each coded code may be mapped to one resource unit or mapped to a specific number of resources by a virtual carrier order. unit.

When performing sequential mapping, the encoded word code is mapped from the lowest (minimum) effective index of the virtual subcarrier in an incremental index direction. For example, when performing dual RM encoding, the first word may be mapped to each odd number of virtual subcarriers starting from an odd number of virtual subcarriers of the least significant index. Moreover, the second word can be mapped to each even number of virtual subcarriers from an even number of virtual subcarriers of the least significant index.

In addition, the mapping method can also be performed in a time-based order. For example, when the allocated resource units individually correspond to the second, fourth, ninth, and eleventh symbols, the first word can be mapped to the second and ninth symbols, and The second word can be mapped to the fourth and eleventh symbols. Alternatively, the first word code can be mapped to a resource unit corresponding to two symbols, and the second word code can be mapped to a resource unit corresponding to the remaining symbol.
