Description

Multiplexing method of data information and control information {METHOD FOR MULTIPLEXING DATA AND CONTROL INFORMATION}

The present invention relates to a method of multiplexing data and control sequences onto a physical channel in a wireless mobile communication system.

The data and control sequences transferred from the media access control layer to the physical layer are encoded and then transmitted over a radio transmission link to a transport and control service. To provide. The channel coding scheme may include error detection, error correction, rate matching, interleaving, and transport channel information or control information in physical channels. This is done by combining the processes that map to. Data transmitted from the MAC layer is configured to include information bits (systematic bits) and non-system bits (bits) by the above channel coding scheme (channel coding scheme). In this case, the non-information bit may be a parity bit.

In 3GPP, the UL-SCH and RACH in the uplink transport channel may be mapped to the PUSCH and PRACH in the physical channel, respectively. In addition, UCI in uplink control channel information may be mapped to a PUCCH and / or a PUSCH. DL-SCH, BCH, PCH, and MCH in the downlink transport channel are mapped to PDSCH, PBCH, PDSCH, and PMCH in the physical channel, respectively. In addition, CFI, HI, and DCI in downlink control channel information are mapped to PCFICH, PHICH, and PDCCH, respectively, in the physical channel. In order for each of the above-described transport channels to be mapped to a physical channel, various processes are performed. In particular, in a channel such as UL-SCH, processing for cyclic redundancy check (CRC) calculation, code block division, channel coding, rate matching, and code block concatenation is performed on one or more transport channels or control information.

1 illustrates a process for a transport channel and / or control information. Data in the form of a maximum of one transport block is input at every transmission time interval (TTI). This transport block can be processed as follows. First, in a CRC attachment block, a CRC is added to data having a form of a transport block. In the code block segmentation block, the CRC added data is divided into one or more code blocks. In the channel coding block, channel coding is performed on a code block data stream of each divided code block. In a rate matching block, rate matching is performed on each channel coded data stream. In a code block concatenation block, one or more rate matched data streams are concatenated to form a sequence of encoded data bits. Meanwhile, the separate channel coding unit performs channel coding on the control information to form a sequence of encoded control bits. The data and control multiplexing block multiplexes the sequence of encoded data bits and the sequence of encoded control bits and outputs the sequence of multiplexed bits.

Here, one or more bits may constitute one symbol according to a modulation order (Qm). For example, BPSK, QPSK, 16QAM, and 64QAM each constitute one symbol of one bit, two bits, three bits, and four bits. Since one symbol is mapped to one resource element (RE) in a system using SC-FDMA, it can be described in units of symbols. Thus, in this document, the terms 'coded data bits', 'coded control bits', and 'multiplexed bits' are referred to as 'coded data symbols' and 'encoded' respectively in consideration of the modulation class. Control symbols, 'and' multiplexed symbols'. Also, the terms' coded data bits', 'coded data symbols',' coded control bits', and 'coded control symbols' are respectively used for the purpose of explanation,' data bits', 'data symbols',' Control bits' and 'control symbols'.

The control information may be classified into one or more types according to its characteristics, and various multiplexing schemes may be considered according to the number of classified types. If only one type of control information exists, the control information may or may not overwrite the data information when the data information and the control information are multiplexed. When two types of control information exist, it may be divided into a first type of control information and a second type of control information. When the second type of control information is more important than the first type of control information, first, when the data information and the control information are multiplexed, the first type of control information may or may not be multiplexed in such a manner as to overwrite the data information. Thereafter, the second type of control information may or may not overwrite the multiplexed data information and / or the first type of control information as above.

2 shows an embodiment of a transport channel processing procedure for UL-SCH of 3GPP. 2 can be understood as a matrix structure of C * R (eg, C = 14), hereinafter referred to as "set of resource elements". Here, C symbols consecutive in the time domain are arranged in the horizontal direction, and R virtual subcarriers are arranged in the frequency domain in the vertical direction. In the set of resource elements, the virtual subcarriers are arranged adjacent to each other, but the carriers on each physical channel corresponding to each virtual subcarrier may be discontinuous in the frequency domain. Hereinafter, in this document, a virtual subcarrier related to a set of resource elements is used in the term of subcarrier. In the standard CP (normal cyclic prefix) structure, 14 symbols (C = 14) constitute one subframe, but in the extended CP (extended cyclic prefix) structure, 12 symbols (C = 12) ) May configure one subframe. That is, FIG. 2 assumes a standard CP structure, and if it has an extended CP structure, FIG. 2 may have a matrix structure of C = 12. Referring to FIG. 2, 'number of symbols' * 'number of subcarriers' = C * R = M symbols per subframe may be mapped. That is, M symbols may be mapped to M resource elements per one subframe. However, in the M resource elements, not only the multiplexed symbol generated by multiplexing the data symbol and the control symbol, but also a reference signal (RS) symbol and / or a sounding RS (SRS) symbol may be mapped. Therefore, when K reference signal (RS) symbols and / or sounding RS (SRS) symbols are mapped, M-K multiplexed symbols may be mapped.

2 shows an example in which two kinds of control information, that is, control information 1 and control information 2 are mapped to a set of resource elements. Referring to FIG. 2, a sequence of multiplexed symbols is mapped by a time-first mapping method. That is, they are sequentially mapped to the right from the first symbol position of the first subcarrier. After the mapping of one subcarrier is completed, the mapping is sequentially performed from the first symbol position of the next subcarrier to the right. Hereinafter, 'symbol' may refer to 'SC-FDMA symbol'. The control information 1 and the data information are mapped in a time-first mapping method in the order of 'control information 1' to 'data information'. Control information 2 is mapped to only the symbols next to the RS symbol in the order of 'last subcarrier' to 'first subcarrier'. Here, the last subcarrier refers to the lowest subcarrier in the set of resource elements of FIG. 2, and the first subcarrier refers to the uppermost subcarrier. Here, the control information 1 is mapped by rate matching with the data information, and the control information 2 is mapped by puncturing the above-matched and matched control information 1 and / or data information. In this case, the data information may be formed by sequentially concatenating a plurality of code blocks divided from one transport block.

When multiplexing data information and control information, consider the following: First, the multiplexing rule should not be changed by the amount, type, and presence of control information. Second, there should be no impact on the transmission of other data in the circular buffer if the control information is multiplexed with the data by rate matching, or if the control information punctures the data and / or other types of control information. Third, the start time of the circular buffer for the next redundant version should not be affected by the presence or absence of control information. Fourth, HARQ buffer corruption should be avoided in a hybrid automatic repeat request (HARQ) transmission scheme. In addition, in the method of mapping the multiplexed information to the data channel, a certain kind of control information should be mapped to a resource element close to RS capable of exhibiting good performance.

In the method of Fig. 2, two types of control information are mapped to the virtual physical channel together with the data information, so a new rule is required to map another type of control information together. In addition, in the method of FIG. 2, when control information 2 punctures data information and / or control information 1, the last code block is performed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of mapping control information by a predetermined rule in consideration of the presence and type of control information, in order to solve the above-mentioned problems of the prior art and shape the performance of a wireless mobile communication system.

It may be written in the order of the index '1', '7', '6', '2'. In this case, when QPSK is used, the above Qm = 2, when 16QAM is used, the above Qm = 4, and when 64QAM is used, the above Qm = 6. In this case, the total number of elements of the matrix is the total number of encoded bits for all RI blocks encoded in the total number H of encoded bits allocated for UL-SCH data and CQI / PMI data (Q). May be equal to the result of multiplying _RI ). In this case, step (a) is performed only when rank information is transmitted in a subframe in which the above data information is transmitted, and step (c) above is HARQ-ACK information in a subframe in which the above data information is transmitted. Can only be performed when is transmitted. In this case, the first vector sequence, the second vector sequence, and the third vector sequence may be sequentially recorded from the first vector element in the sequence.

At this time, in the above step (a), the first control information is mapped in the upward direction starting from the last row of the matrix, or the first control information is included in the above column including the last column of the matrix. Starting in a specific column of the matrix above and mapping in the downward direction so that the first control information of is mapped, in step (b) above, the sequence is mapped in the downward direction starting from the first row of the matrix above, In step (c) above, the third control information above maps in the upward direction starting from the last row of the matrix above, or the third control information above includes the last column of the matrix above. 3 control information may be mapped in a downward direction starting from a specific column of the above matrix. Further, in step (b) above, the symbols of the above sequence that are mapped in each row may be mapped in the left direction, the right direction, or in a specific order in each row above. Further, in the above step (a), the symbol of the above first control information mapped to each row is the above matrix corresponding to the resource element spaced apart by the above one resource element in each row above.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The detailed description set forth below in conjunction with the appended drawings is intended to explain exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced. The following detailed description includes specific details to assist in a thorough understanding of the present invention. However, those skilled in the art will appreciate that the invention may be practiced without these specific details. For example, the following description will focus on certain terms, but need not be limited to these terms and may refer to the same meaning even when referred to as any term. In addition, the same or similar components throughout the present specification will be described using the same reference numerals.

The suffixes "module" and "unit" for components used in the following description are merely given in consideration of ease of preparation of the present specification, and do not impart any particular meaning or role by themselves. Therefore, it should be noted that the "module" and "unit" may be used interchangeably with each other.

In an actual implementation, each of the components on the block diagram may be divided into two or more hardware chips, or two or more components may be integrated into one hardware chip.

Embodiments according to the present invention described below can be used for transport channel processing for 3GPP, in particular for the UL-SCH.

Control information can be classified into various types. In this case, the classification criteria may be based on any criteria, or may be based on the importance of the control information. In this case, the importance may be determined by evaluating the degree of influence on the performance of the wireless mobile communication system when transmission of some type of control information fails. When multiple types of control information exist, a new multiplexing scheme is required to improve the performance of a wireless mobile communication system. For example, more important types of control information may be multiplexed in a way that is not overwritten by less important types of control information.

In the present invention, the control information 1 is, for example, a combination of channel quality information (CQI), which is information indicating channel quality, and a precoding matrix index (PMI), which is index information of a codebook used for precoding. It may be CQI / PMI. This control information 1 can be multiplexed with the data information by rate matching. In the present invention, the control information 2 may be, for example, ACK / NACK (ACKnowledgement / Negative ACKnowledgement) which is an HARQ response. The control information 2 may be multiplexed by puncturing the data information or the control information 1. In the present invention, the control information 3 may be, for example, RI (Rank Indication or Rank Information) which is information indicating the number of transport streams. The control information 3 may be multiplexed in a manner that flattens the data information or the control information 1 or is rate matched with the data information and / or the control information 1.

Embodiments presented in the present invention can be modified and applied to the up, down, left and right structure with respect to the sub-carrier axis and the symbol axis (time axis) on the set of resource elements. Hereinafter, in the embodiment of the present invention, the 'symbol' may be an SC-FDMA symbol.

In the present invention, 'puncturing' refers to a process of removing a specific bit (or symbol) and inserting a new bit (or symbol) in a sequence consisting of several bits (or symbols). That is, by replacing part of the information with other information, when data information or control information is multiplexed, the puncturing information replaces a bit (or symbol) of the punctured information. According to the puncturing method, even when new information is inserted, the length of the entire bit (or symbol) is maintained and affects the code rate of the punctured information.

In the present invention, 'rate matching' is to adjust the coding rate of data information. When data information or control information is multiplexed, the bits before the multiplexing may be changed even though the position of each information may be changed. Symbol) does not affect itself. That is, here, the "rate matching" of the control information 1 and the data information means processing so that the sum of the amount of the control information and the data information that is rate matched has a constant size. Therefore, when the amount of control information 1 to be transmitted increases, the amount of data information that is rate matched with the control information 1 decreases by that amount.

3 to 6 are diagrams for defining terms commonly used to describe the embodiment according to FIG. 7 of the present invention.

The set of resource elements illustrated in FIGS. 3 to 7 described below is based on the configuration of a standard CP, and for the sake of explanation, it is assumed that C * R = M resource elements. Here, 'C' represents the number of 'symbol intervals' arranged in the time axis direction, and 'R' represents the number of R subcarriers arranged in the virtual frequency direction. Here, the 'symbol period' means a time period in which one symbol exists, and therefore, the length of one symbol period is equal to the length of one symbol.

In addition, for the following description, in the entire area of the set of resource elements, the subcarrier located in the first row above is defined as 'subcarrier 0', and the subcarrier located in the last row is defined as 'subcarrier R-1'. do. That is, the first subcarrier in the transmission band is defined as 'subcarrier 0', and is defined as 'subcarrier 1', 'subcarrier 2', etc. in the downward direction, and the last subcarrier is defined as 'subcarrier R-1'. Can be defined as

3 (a), 3 (b), 4 (a), and 4 (b) are diagrams for explaining a concept for describing an embodiment of the present invention. Hereinafter, in this document, the terms 'first subcarrier' and 'last subcarrier' are used in reference to a specific time-frequency domain (hereinafter, 'region A') defined for some or all of the entire set of resource elements. The region A refers to any region in the entire set of resource elements, and each resource element in the region A may be spaced apart from each other in time or frequency, as shown in FIG. The first subcarrier in region A refers to the subcarriers in the top row of region A, and the last subcarrier in region A refers to the subcarriers in the bottom row in region A. In addition, the 'first resource element' ('F') and 'last resource element' ('L') are used in relation to the area A. That is, the 'first resource element' of the area A refers to the resource element that is the most advanced resource element in time, that is, the leftmost row of the first subcarriers of the area A, and the 'last resource element' of the area A is the last subcarrier of the area A. Refers to the resource element that is located last in time, that is, the resource element in the rightmost row. In addition, within one subcarrier, a first resource element refers to a resource element that advances in time within that subcarrier, and a last resource element refers to a resource element that is located last in time within the subcarrier.

Referring to (a) of FIG. 5, the RS is mapped to an 'RS symbol interval' composed of 'RS symbol interval 0' and 'RS symbol interval 1' which are not adjacent to each other. The 'RS symbol interval area' is an area including 2 * R resource elements located in the RS symbol period. The RS symbol interval region may be divided into an 'RS symbol interval region 0' and a 'RS symbol interval region 1'. The 'RS symbol interval region 0' and the 'RS symbol interval region 1' each have N resource elements in the frequency direction.

Referring to FIG. 5B, the 'first symbol interval' is defined as four symbol intervals spaced by zero symbol intervals from the RS symbol interval. The first symbol interval region is an area including 4 * R resource elements located in the first symbol interval. Accordingly, in FIGS. 3 to 6, the 'first symbol interval region' refers to 'first symbol interval region 0', 'first symbol interval region 1', 'first symbol interval region 2', and ' It may be defined again by dividing into the first symbol period region 3 '.

Referring to FIG. 5C, the 'second symbol interval' is defined as four symbol intervals spaced by one symbol interval from the RS symbol interval. The 'second symbol interval area' is an area including 4 * R resource elements located in the second symbol period. Accordingly, in FIGS. 3 to 6, the 'second symbol interval region' refers to a 'second symbol interval region 0', 'second symbol interval region 1', 'second symbol interval region 2', and It may be defined again by dividing into the 'second symbol interval region 3'.

Since the positions of the RS symbol sections shown in FIGS. 3 to 7 may be changed while keeping the RS symbol section 0 and the RS symbol section 1 spaced apart from each other, the first symbol section and the second symbol section are changed. Should be understood in the relative position with respect to the RS symbol interval.

The above 'RS symbol interval region', 'first symbol interval region' and 'second symbol interval region' may be regarded as examples of the above-described 'region A'.

In the description of the present invention, the term 'forward mapping order' is used in connection with the above-mentioned area A. The mapping in the forward mapping order from a specific resource element in the region A means that in the region A, it is mapped from the subcarrier to which the above specific resource element belongs in the order of top to bottom, and in each subcarrier is mapped over time. That is, the two-dimensional mapping method which maps in the order of the direction from the left row to the right row. For example, when the mapping is performed in the forward mapping order from the first resource element of the entire region of the set of resource elements in FIG. 3A, the direction of the arrow (dotted line) is in the order of subcarrier 0 to subcarrier N-1. Mapping (see FIG. 6A). In contrast, the term 'reverse mapping order' is intended to indicate a method of mapping in a reverse order to the above forward mapping order. That is, the mapping in the reverse mapping order from a specific resource element in the area A means the mapping from the subcarrier to which the above specific resource element belongs in the order from the bottom to the upward direction. It refers to a two-dimensional mapping method that maps back, that is, maps in the order of the right row to the left row. For example, when mapping from the last first resource element of the entire area of the set of resource elements of FIG. 3 (a) in reverse mapping order, mapping is performed according to the direction of an arrow (dotted line) in the order of subcarrier N-1 to subcarrier 0. (See (b) of FIG. 6).

Although the set of resource elements shown in FIGS. 3 to 7 described below is based on the configuration of the standard CP, it can be understood that the same method can be described even under the configuration of the extended CP including 12 symbols. have.

7 illustrates a method of multiplexing and mapping data information and control information onto a set of resource elements according to an embodiment of the present invention.

In FIG. 7, control information 1 may be mapped to one or more consecutive first or more resource elements including the first resource element, except for the resource element to which the RS is mapped in the entire set of resource elements. Control information 2 is mapped to the above-described first symbol interval region, and control information 3 is mapped to the above-mentioned second symbol interval region. That is, the control information 2 is mapped to the symbol section adjacent to before and after the symbol section in which the RS is mapped, and the control information 3 is mapped to the symbol section separated by one symbol section from the symbol section in which the RS is mapped. The control information 2 may be mapped in a forward or reverse direction or a specific mapping order in the first symbol interval region. The control information 3 may be mapped in a forward or reverse direction or a specific mapping order in the second symbol interval region.

At this time, if the control information 3 is multiplexed in a puncturing manner, the control information 3 is mapped to the second symbol interval region, that is, the control information 1 is mapped to the resource element next to the resource element to which the control information 2 is mapped. There is an advantage that can reduce the puncture.

In FIG. 7, the control information 1 does not puncture data information. That is, control information 1 is rate matched with data information. In addition, the control information of different characteristics may be configured in a concatenated form. The control information 2 may puncture the data information and / or the control information 1 in the first symbol interval region. The control information 3 may puncture the data information and / or the control information 1 in the second symbol period region. Alternatively, the control information 2 and / or the control information 3 may be transmitted through a resource element obtained through rate matching with respect to the data information. For example, the control information 2 punctures the data information and the control information 1, and the control information 3 is mapped in the form of being rate matched with the data information and / or the control information 1 and inserted between the data information and / or the control information 1. Can be.

If the number of symbols of the control information 2 is larger than the number of resource elements in the first symbol interval region, the control information 2 may puncture the control information 1 even outside the first symbol interval region. When the number of symbols of the control information 3 is larger than the number of resource elements in the second symbol interval region, the control information 3 may puncture the control information 1 even outside the second symbol interval region.

 In the above-described embodiment according to FIG. 7, the above control information 1 may be multiplexed with data information before being mapped on the set of resource elements. That is, the multiplexed stream can be generated by multiplexing the control information 1 and the data information so that the data information is arranged after the control information 1. Then, the above multiplexed streams are mapped in a forward mapping order from the first resource element of the entire area of the set of resource elements, or vice versa in a backward mapping order from the last resource element of the entire area of the set of resource elements. can do. In this way, the control information 1 is one or more consecutive resource elements including the first resource element or the last resource element, except for the resource element to which the RS is mapped, in the entire area of the set of resource elements as described above. Can be mapped to. Also, it can be understood that the above-described embodiments can be used even when the control information 1 does not exist. If the control information 2 does not exist, the control information 1 and the control information 3 are mapped to the state in which the control information 2 is omitted in FIG. 7, and when the control information 3 does not exist, the control information 1 and the control information 2 In FIG. 7, the control information 3 may be missing.

In the method according to FIG. 7, the position of the control information 3 will be described in more detail with reference to Tables 1 to 9 below.

In the method of FIG. 7, the position of the control information 3, that is, the second symbol interval may be defined by any one of Tables 1 to 9 listed below by way of example. Tables 1 to 9 show symbol periods in which control information 3 can be mapped according to a CP configuration and an SRS configuration. Although FIG. 7 assumes a standard CP, the same method may be used for an extended CP.

FIG. 8A illustrates a configuration according to an embodiment in which a standard CP is used, and FIG. 8B illustrates a configuration according to an embodiment in which an extended CP is used.

In general, the symbol period in which the data information and the control information are available may be changed by the configuration of the CP and the configuration of the SRS. When a standard CP is used, as shown in FIG. 8A, one subframe includes 14 symbol sections. In this case, in Tables 1 to 9, it is assumed that RS is positioned in the fourth ('④') and the eleventh ('⑪') symbol periods of the 14 symbol periods. In addition, when the extended CP is used, as shown in FIG. 8B, one subframe includes 12 symbol sections. In this case, it is assumed in Tables 1 to 7 that RS is positioned in the fourth ('④') and tenth ('⑩') symbol periods of the twelve symbol periods. On the other hand, unlike the above assumption, the symbol section in which the RS is located may be changed differently from those in Tables 1 to 9, and at this time, the symbol sections in which data information and control information can be mapped are shown in Tables 1 to 9 It is to be understood that the changes may be different from the case.

In Tables 1 to 9, a number written in '{}' of a row labeled "Column Set" represents a symbol section in which control information 3 can be mapped. However, this number is allocated except for the symbol period in which the RS is mapped in FIGS. 8A and 8B. That is, the number written in '{}' indicates a symbol section corresponding to the number arranged at the bottom of (a) and / or (b) of FIG. 8. The number written in '{}' may have a value of '0' to '11' in the case of the standard CP, and a value of '0' to '9' in the case of the extended CP.

In addition, Tables 1 to 9 include a configuration in which the SRS is mapped in the first symbol interval and a configuration in the last symbol interval. "First SC-FDMA symbol" described in Tables 1 to 9 refers to the case where the SRS is mapped to the first symbol, "Last SC-FDMA symbol" refers to the case where the SRS is mapped to the last symbol, "No SRS "refers to the case where the SRS is not mapped.

In Table 1, in the Last SC-FDMA symbol of the extended CP, one of several "Column set" can be used.

In case of the extended CP, exceptionally, the SRS may not be mapped in the last symbol period, or the SRS may be dropped even if allowed. In this case, as shown in Table 2, the "Last SC-FDMA symbol" may have the same "Column set" as "No SRS".

The configuration of the " Last SC-FDMA symbol " of the extended CP of Table 3 indicates that the position of the symbol section in which the control information 3 is mapped may change due to the SRS.

In case of the extended CP, exceptionally, the SRS may not be mapped in the last symbol period, or the SRS may be dropped even if allowed. In Table 4, the "Last SC-FDMA symbol" SRS may be used in the extended CP when the "Last SC-FDMA symbol" SRS can be dropped even if it is not exceptionally allowed or allowed, and the first SC-FDMA symbol SRS is not used. If not, the first SC-FDMA symbol portion (including "Column set") may be omitted.

Referring to FIGS. 8A and 8B, it can be seen that the configuration of each "Column set" in Table 5 corresponds to the above-described second symbol interval region. That is, in each configuration, it can be seen that the control information 3 is mapped to a symbol section that is separated by one symbol section from the symbol section to be mapped. In this case, in the case of the configuration of the "Last SC-FDMA symbol" in the extended CP, the number 9 indicates the position of the SRS. However, the SRS is dropped even if the SRS is not allowed to be mapped in the last symbol section or is allowed. In such a case, such a configuration can be used. In addition, regardless of the SRS configuration, since the position of the "Column set" in each CP configuration is the same, when configuring Table 5, it can be displayed in a form without the SRS configuration.

Referring to FIGS. 8A and 8B, it can be seen from Table 6 that each configuration except for the "Last SC-FDMA symbol" configuration in the extended CP corresponds to the above-described second symbol interval region. . In addition, according to each configuration of Table 6, it can be seen that the control information 3 is not mapped to the above-described resource element of the first symbol interval. In Table 6, the control information 3 in the "Last SC-FDMA symbol" configuration in the extended CP is It is not mapped to the symbol section '9'. The reason is that the SRS is mapped to the position of the symbol section '9'. Comparing Table 6 with Table 5, it can be seen that the configuration of the "Last SC-FDMA symbol" is different in the extended CP. That is, in Table 5, the control symbol 3 located in the symbol section '9' is mapped to the symbol section '5', which is a symbol section not adjacent to the symbol section in which the RS is mapped in Table 6. In the extended CP of Table 6, in the "Last SC-FDMA symbol" configuration, "Column set" is displayed in the order of {1, 4, 6, 5}, where the symbol section '6' is mapped to the symbol section '5'. Since it is closer to the symbol interval, the symbol interval '6' may have priority over the symbol interval '5'. That is, in the process of uniformly filling control information in each symbol section, if the control information should be filled in only one symbol section of symbol section '6' and symbol section '5', the symbol section '6' may have priority. to be. However, even if "Column set" is indicated in the order of {1, 4, 6, 5}, the priority may have the order of {1, 4, 5, 6}. What is important is the position of the symbol section in which control information 3 is mapped.

Referring to FIGS. 8A and 8B, it can be seen from Table 7 that each configuration of the extended CP corresponds to the aforementioned second symbol interval region. In addition, according to each structure of Table 7, it turns out that control information 3 does not map to the resource element of a 1st symbol period mentioned above. Unlike Table 5 and Table 6, in Table 7, the extended CP has the same "Column set" configuration regardless of the SRS configuration. In the extended CP of Table 6, in the "Last SC-FDMA symbol" configuration, "Column set" is displayed in the order of {1, 4, 6, 5}, where the symbol section '6' is mapped to the symbol section '5'. Since it is closer to the symbol interval, the symbol interval '6' may have priority over the symbol interval '5'. That is, in the process of uniformly filling control information in each symbol section, if the control information should be filled in only one symbol section of symbol section '6' and symbol section '5', the symbol section '6' may have priority. to be. However, even if "Column set" is indicated in the order of {1, 4, 6, 5}, the priority may have the order of {1, 4, 5, 6}. What is important is the position of the symbol section in which control information 3 is mapped. In Table 7, regardless of the configuration of the SRS, since it has the same "Column set" in each CP, Table 7 can be displayed in a form without the configuration of the SRS.

9 (a) and 9 (b) are structures in an exemplary extended CP. This is a figure for explaining the structure by following Table 8 and Table 9.

Table 8 shows a configuration when the symbol section in which RS is mapped in the extended CP is changed. In particular, in Table 8, it is assumed that RS is positioned in the third ('③') and the ninth ('⑨') symbol periods of the symbol period (see FIG. 9A). According to the configuration of the extended CP shown in Table 8, the control information 3 is mapped to the symbol interval separated by one symbol interval from the symbol interval on which the RS is mapped. That is, it is mapped to the above-described second symbol period. Referring to the configuration of Table 8, it can be seen that the position of the symbol section in which the control information 3 is mapped may be modified according to the positions of the RS and the SRS.

Table 9 shows a configuration when the symbol section in which RS is mapped in the extended CP is changed. In particular, in Table 9, it is assumed that the RS is located in the fourth ('④') and the ninth ('⑨') symbol period of the symbol interval (see Fig. 9 (b)).

10 and 11 illustrate examples of positions where an SRS and an RS are allocated in one subframe in the case of a standard CP and an extended CP, respectively.

10 and 11 correspond to (a) and (b) of FIG. 8, respectively, and illustrate a case in which the SRS is not mapped or the SRS is mapped to the last symbol. The control information 3 is mapped by a symbol length apart from the symbol interval in which the RS is mapped in consideration of the modulation class on the basis of the symbol. Therefore, in FIG. 10, control information 3 is mapped to symbol sections having indices of 1, 4, 7, and 10, and in FIG. 11, control information 3 is mapped to symbol sections having indexes of 1, 4, 6, and 9. do.

12 illustrates a sequence in which control information 2 and / or control information 3 are mapped in the time direction within one subcarrier.

Control information 2 and control information 3 may be mapped to up to four resource elements for each subcarrier, respectively. 12 shows an order in which symbols are mapped for four resource elements in one subcarrier. Although the number of the symbol where each control information is mapped according to the type of CP may be changed, the indexing order may be relatively determined as shown in FIG. 12. In FIG. 12, the number of symbols after encoding is 10 and a standard CP without SRS is shown as an example.

Hereinafter, FIGS. 12A to 12F will be described based on control information 2.

In (a) of FIG. 12, the sub-carriers of the first symbol interval region are mapped in the upward direction, and are mapped over time in each sub-carrier. In this case, all of the control information 2 is mapped to the four available resource elements in the last subcarrier of the first symbol interval region.

FIG. 12B illustrates a method of mapping down from a specific subcarrier in the first symbol interval region in consideration of the number of symbols of control information 2, and over time within each subcarrier. In this case, all of the control information 2 is mapped to the four mappable resource elements in the specific subcarrier, and the control information 2 is mapped to the resource element in the last subcarrier of the first symbol interval region.

FIG. 12C illustrates a method of mapping down from a specific subcarrier of the first symbol interval region in consideration of the number of symbols of control information 2, and over time within each subcarrier. In this case, the control information 2 is mapped to all four mapable resource elements in the last subcarrier of the first symbol interval region.

FIG. 12D illustrates a method of mapping from the last subcarrier of the first symbol interval region in the order of upward direction, and mapping the flow of time within each subcarrier. In this case, the control information 2 is mapped to all four mapable resource elements in the last subcarrier of the first symbol interval region.

FIG. 12E illustrates a method of mapping from the last subcarrier of the first symbol interval region in the upward direction in consideration of the number of symbols of control information 2, and mapping the flow of time within each subcarrier. At this time, the control information 2 is all mapped to the four potential resource elements in the uppermost subcarrier.

FIG. 12F is a method in which the method of FIG. 12D is modified to modify the order of mapping to four resource elements in each subcarrier. That is, the arrangement method for mapping against the passage of time within each subcarrier is a method for cyclic shifting by one to the right. It may also be cyclically shifted by 2 or 3 for mapping.

12A to 12F have been described with reference to the control information 2, it can be understood that the control information 3 can be applied in the same manner.

FIG. 13 to FIG. 15 illustrate the method of FIG. 12 in more detail. FIG. 12 illustrates an example of applying the method of FIG. 12 to a set of resource elements having a matrix structure of C * R. 13 (a) and 13 (b) correspond to FIGS. 12 (a) and 12 (b), respectively, and FIGS. 14 (a) and 14 (b) are respectively shown in FIG. 12. (c) and (d) of FIG. 12, and (a) and (b) of FIG. 15 correspond to (e) and (f) of FIG. 12, respectively.

2 to 15 have been described using a set of physical resource elements including resource elements mapped to RS in order to indicate a relative relationship between a location where data information and control information are mapped and a location where an RS is mapped. . Here, it can be understood that the above-described embodiments can be described using the structure of the time-frequency matrix excluding the resource element where RS is mapped in the set of physical resource elements.

Data and control information mapped and output on the above-described set of physical resource elements of FIGS. 2 to 15 may be scrambled and modulated mapped, as described with respect to the processing of the PUSCH of 3GPP TS 36.211. After that, it may be input to a resource element mapper through a transform precoder. In addition, the abbreviations in this application refer to the abbreviations described in 3GPP TS 36.212.

Hereinafter, in the method of FIG. 7 according to the present invention, an embodiment of multiplexing control information CQI / PMI and RI with data information will be described for 3GPP TS 36.212 V8.2.0.

Below, Represents input data, Represents input rank information (RI), Denotes the multiplexed output. here to be.

Multiplexing is possible through the processing steps described below.

1. The number of symbols per subframe is determined by the following formula.

here, Is the number of symbols of SC-FDMA carrying PUSCH in one subframe. And, Is the number of symbols in one uplink slot. And Is the number of symbols used for SRS transmission in one subframe.

2. The number G 'of modulation symbols of data information is determined by the following formula.

G '= G / Qm1 (Qm1: modulation order of the data)

3. The number Q 'of modulation symbols of rank information is determined by the following formula.

Q '= Q / Qm2 (Qm2 is the modulation class of rank information)

4. Determine the number K of subcarriers occupied by the modulation symbol of the rank information.

K = ceil (Q '/ maximum number of resources for rank information)

5. Determine the number of modulation symbols of rank information per symbol.

Calculate the amount that can be entered per symbol where the rank information is located.Based on Q ',' floor 'and' ceil 'can be combined at the symbol position where each rank information is located or divided by the number that can be included in the symbol. The number of modulation symbols of rank information that each symbol in which rank information may be located may be determined using a method such as a method. At this time, it can be divided equally into two slots as much as possible, and also can be allocated in the direction of the rear slot or the reverse direction from the front slot.

6. Multiplex modulation symbols of data information and rank information.

Ultimately, since the rank information should be stacked from the bottom of the subcarrier, the data information should be mapped in a time-first manner, and the rank information should be mapped in the corresponding symbol. At this time, since the data information is mapped from the subcarriers of the top part, subtracting two results from the total number of subcarriers indicates the location of the subcarriers where the rank information can be located. Therefore, the rank information is considered in consideration of the number of symbols determined in step 3 from this time. Map it. This is expressed as pseudo code as follows.

================================================== ===========================

For (from subcarrier 0 to the last subcarrier) {

   If (if current subcarrier number is less than total subcarrier minus K)

{

      for (from SC-FDMA symbol 0 to the number of SC-FDMA symbols per subframe)

      {

         Map data to output one symbol

         SC-FDMA symbol count increment

         Increment data symbol count

      }

   else {

      for (from SC-FDMA symbol 0 to the number of SC-FDMA symbols per subframe)

        {

         if (if the number of modulation symbols of rank information in the corresponding SC-FDMA symbol calculated in step 4 is zero) {

            Map data to output one symbol

            SC-FDMA symbol count increment

            Increment data symbol count

         }

         else {

            Map rank information to output by 1 symbol

            SC-FDMA symbol count increment

            Rank information count increases

            The number of modulation symbols of rank information is deleted by 1 from the corresponding SC-FDMA symbol calculated in step 4.

         }

      }

   }

   Increment count of subcarriers

}

================================================== ===========================

Details of how the rank information is located between data due to a rate matching method other than puncturing may be used in whole or in part.

Hereinafter, in the method of FIG. 7 according to the present invention, another method of applying an embodiment of multiplexing control information CQI / PMI and RI with data information to 3GPP TS 36.212 V8.2.0 will be described.

The following method is an example, when the amount of RI does not invade resources occupied by CQI / PMI (the number of subcarriers including symbols occupied by RI and the number of subcarriers occupied by CQI / PMI are transmitted per subframe. It does not exceed the total number of subcarriers used for Therefore, the amount of RI, CQI / PMI, and data information should be considered as a size that does not interfere with each other. If there is a case of invading each other, the RI may use a method of puncturing the CQI / PMI and modify the following method.

here, Represents the CQI / PMI input, Indicates input of data information, (Code bits) or (Vector sequence, symbol form considering modulation class) represents an RI input. And, Indicates output. Here, H = (G + Q + Q _RANK ) and H '= H / Qm when RI is a code bit, and H' = H / Qm + Q ' _RANK when RI is a vector sequence.

The number of subcarriers used for rank information in one subcarrier may be divided into two types as follows. That is, if RI is a code bit It may be displayed as follows. Here, 4 is the maximum number of resources for the RI, and if it is just divided by the number, it may not use the sign up / down. Otherwise, if RI is a vector sequence Can be displayed as: Here, 4 is the maximum number of resources for the RI, and if it is just divided by the number, it may not use the sign up / down.

The number of rank information encoded in the bit / vector sequence in the i-th symbol carrying the PUSCH in one subframe is represented by ni.

For the number of coded bit / vector sequences for rank information mapped to each symbol carrying a PUSCH for a subframe having a standard CP, see Tables 10 to 12. Table 10 shows the values of ni in subframes with standard CPs. Table 11 shows ni values in a subframe having an extended CP without SRS. Table 12 shows ni values in a subframe having an extended CP having an SRS in the last symbol.

In Table 10, it is aimed at dividing the two slots and the RI where symbols can be located as evenly as possible (even). In this case, the method of using uniformly may be performed by using up / down / modulo or the like, and may be changed according to the position priority of the symbol where the RI may be located if necessary. In other words, the number of i may vary from 1 by 1>4>7> 10 or 1>7>4> 10 or 4>7>1> 10, and so on. Can be modified. In addition, two cases of Q _RANK and Q ' _RANK are mentioned. If RI is a coded bit, an equation using Q _RANK can be used, and if RI is a vector sequence, an equation using Q' _RANK can be used.

In Table 11, the purpose is to divide the two slots and the symbols where the RI can be located as evenly as possible. In this case, the uniformly used method may be performed by using up / down / modulo and the like, and may be changed according to the position priority of a symbol where RI may be located if necessary. That is, the number of i may vary from about 1 by 1>4>6> 9 or 1>6>4> 9 or 4>6>1> 9, and so on. Can be modified. In addition, two cases of Q _RANK and Q ' _RANK are mentioned. If RI is a code bit, an equation using Q _RANK can be used, and if RI is a vector sequence, an equation using Q' _RANK can be used.

In Table 12, the purpose is to divide the two slots and the symbols where the RI can be located as evenly as possible. In this case, the method of uniformly using may be performed by using up / down / modulo and the like, and may be changed according to the position priority of the SC-FDMA symbol where RI may be located if necessary. That is, the number i may vary from about 1 by 1>4>6> 5 or 1>6>4> 5 or 4>6>1> 5, and so on. Can be modified. In addition, two cases of Q _RANK and Q ' _RANK are mentioned. If RI is a code bit, an equation using Q _RANK can be used, and if RI is a vector sequence, an equation using Q' _RANK can be used.

The control information, rank information and data information can be multiplexed as follows.

================================

==================================

The control data arrives at the coding unit in the form of channel quality information (CQI and / or PMI), HARQ-ACK and rank indication. By assigning different numbers of coded symbols for transmission of control information, different coding rates for control information can be obtained. When control data is transmitted in the PUSCH, channel coding, rank indicator, and channel quality information for HARQ-ACK Channel coding for is performed independently.
