The technical FIELD

[0001] the Present invention relates to a system for wireless mobile communications and, more in detail, the device for data transmission uplink communication and control information in wireless mobile communications, multiple transmitting antennas and multiple receiving antennas (MIMO), and transfer method.

The LEVEL of TECHNOLOGY

[0002] In the mobile communication system user equipment can receive information in downlink from the base station, and may transmit information in uplink communication. Information transmitted or received by user equipment may include data and various kinds of control information. Various physical channels exist in accordance with the type or frequency of use of information transmitted or received by user equipment.

[0003] figure 1 presents a diagram for the explanation of the physical channels used for a system partner of the project on systems of the 3rd generation (3GPP), and transmission signals using these channels.

[0004] If the power is turned on the user equipment or the user equipment moves into a new cell, the user equipment can perform the initial search cell for coordination of sin is anizatio with the base station or similar operation [step S101]. To do this, the user equipment may receive from the base station of the primary sync channel (primary synchronization channel P-SCH) and a secondary sync channel (secondary synchronization channel S-SCH)may coordinate the synchronization with the base station and may then obtain information such as the identifier (ID) of a cell and similar information. Then the user equipment may receive from the base station a physical broadcast channel and then may be able to receive broadcast information in a cell. In addition, the user equipment may receive the reference signal downlink (downlink reference signal, DL RS) and then may be able to check the status of the channel downlink (DL).

[0005] After the initial search of the cell, the user equipment can take physical control channel downlink physical downlink control channel, PDCCH) and a physical shared control channel downlink physical downlink shared control channel, PDSCH) in accordance with the physical control channel downlink physical downlink control channel, PDCCH) and then may be able to get detailed system information [step S102].

[0006] in Addition, the user equipment which has failed in the completion of the access to the base station, can the be able to perform a random search procedure (procedure RACH) to the base station for complete access [steps S103 through S106]. To do this, the user equipment may transmit a specific sequence as a preamble through a physical random access channel (PRACH) [step S103] and then you may be able to receive the response message through the physical downlink control channel (PDCCH) and a physical shared downlink control channel (PDSCH) in response to a random access [step S104]. In the case of random access based on the conflict resolution user equipment may be able to perform this procedure for the resolution of conflicts, as the transfer (step S105) additional physical random access channel and the reception (step S106) physical downward control channel and corresponding physical shared downstream channel.

[0007] using the above procedure, the user equipment may be able to execute reception (step S107) channels PDCCH/PDSCH (physical downlink control channel/physical shared downlink control channel) and transmit (step S108) channels PUSCH/PUCCH (physical shared uplink channel/physical uplink control channel) as the primary transfer process of the ascending/descending signals.

[0008] figure 2 presents a diagram for describing processing of signals for the user is skogo equipment for signal transmission of the upward communication channel (UL).

[0009] First, transmission of the upward communication channel (UL) scramblase module 210 of the user equipment is able to scramble the transmission signals using a signal scrambling for a specific user equipment (UE). This scrambled signal received at the input of the modulating display device 220, and then is modulated in a complex symbol by binary phase modulation (BPSK, binary phase shift keying, quadrature phase modulation (QPSK, a quadrature phase shift keying) or 16-point quadrature amplitude modulation (QAM, a quadrature amplitude modulation) in accordance with the type and/or condition of the channel signal transmission. Then the complex symbol is processed by the device 230 preliminary coding conversion, and then is fed to the input device 240 display of resource elements. In this case, the device 240 display of resource elements has the ability to display complex symbol in the time-frequency resource element to be actually used for transmission. This processed signal is fed to the input of the generator 250 signal multiple access frequency division on single-carrier (SC-FDMA), and may then be transmitted to the base station through the antenna.

[0010] figure 3 presents a diagram for describing% the SAR signal processing to the base station for signal transmission of a downward communication channel (DL).

[0011] In the system of long-term development partner of the project on systems of the third generation (3GPP LTE) base station is able to transmit at least one code word in a top-down link (DL). Therefore, each of this at least one code word can be processed in a complex symbol by scrambling module 310 and the modulating device 302 display similar to the upward communication line shown in figure 2. Next, a complex symbol can appear on multiple levels through device 303 display levels. Then any of the many levels can be assigned to any of the transmitting antenna by multiplying on the assigned matrix pre-coding selected by module 304 pre-coding in accordance with the state of the channel. The transmission signals for each antenna that are processed in the way described above, is displayed on the time-frequency resource element that will be used for transmission, via any device 305 display of resource elements, is fed to the generator 306 signals multiple access orthogonal frequency division (OFDMA, orthogonal frequency division multiple access) and then can be transmitted via a corresponding antenna.

[0012] If the user equipment is the W in the mobile communication system transmits a signal on the rising channel (UL), this can cause the problem of the correlation peak value signal to the average signal value (PAPR, peak-to-average ratio), more serious than the case for the base station to transmit a signal in a top-down link (DL). Unlike schemes multiple access orthogonal frequency division (OFDMA)is used for signal transmission of a downward communication channel (DL), as described with reference to Figure 2 and Figure 3, for signal transmission of the upward communication channel (UL) can be used multiple access frequency division on single-carrier (SC-FDMA single carrier-frequency division multiple access).

[0013] figure 4 presents a drawing for describing the schema of multiple access frequency division on single-carrier (SC-FDMA) transmission of the upward communication channel (UL) and schemes multiple access orthogonal frequency division (OFDMA) transmission of a downward communication channel (DL) in the mobile communication system.

[0014] the First user equipment to transmit a signal of the upward communication channel (UL) and a base station for signal transmission of a downward communication channel (DL) are identical to each other in that they include a series-parallel Converter 410, the unit 403 of the display sub-module 404 inverse discrete Fourier transform (IDFT) with M points and the module 46 adding a cyclic prefix (CP).

[0015] in Addition, a user equipment for transmission of signal through a scheme SC-FDMA may further include a parallel-to-serial Converter 405 and the module 402 of the discrete Fourier transform (DFT) with N points. This module 402 of the discrete Fourier transform (DFT) with N points can be characterized by the fact that allows signal transmission to be set to one of the bearing by removing the influence of processing discrete inverse Fourier transform (IDFT) module 404 inverse discrete Fourier transform (IDFT) with M points. Figure 5 presents a drawing describing the mapping of signals in the frequency domain, to fit in the frequency domain properties of a single frequency. Figure 5 (a) shows a diagram of the localized display, while Figure 5 (b) shows a diagram of a distributed display. Currently, the scheme localized display is determined by the standards of long-term development of systems partner of the project on systems of the 3rd generation (3GPP LTE).

[0016] In the following description cluster multiple access frequency division on the same carrier (clustered SC-FDMA) will be considered as a modified form of multiple access frequency division on the same carrier (SCFDMA). First of all cluster multiple access often the major division on the same carrier (clustered SC-FDMA) is characterized by the division of the output samples of the process of the discrete Fourier transform (DFT) in the process of mapping subcarriers into subgroups, and subgroups are in the field of subcarriers located at a distance from each other, in the input block of samples of the inverse fast Fourier transform (IFFT), respectively, between the process of the discrete Fourier transform (DFT) and the inverse process of the fast Fourier transform (IFFT). Thus clustered SC-FDMA can sometimes enable the filtering process and the process of cyclic extensions.

[0017] In this case, the subset may be referred to as a cluster. This cyclic extension may indicate that the guard interval is longer than the maximum interval (range) delay of the channel is placed between adjacent symbols to avoid intersymbol interference (inter-symbol interference, ISI), while the symbol of each subcarrier is transmitted through a multi-band channel.

[0018] figure 6 shows a diagram of the process of signal processing to display the output timing of the process of the discrete Fourier transform (DFT) in one carrier in a clustered SC-FDMA.

[0019] figure 7 and Fig presents a process diagram of signal processing to display the output timing of the process of the discrete Fourier transform (DFT) on a lot of bearing in a clustered SC-FDMA. In particular, figure 6 shows an example of the application of clustered SC-FDMA inside the carrier and 7 and Fig shows examples of the application of clustered SC-FDMA between carriers.

p> [0020] in Addition, figure 7 shows an example of generating a signal using a single block of the inverse fast Fourier transform (IFFT), if the allocation of subcarriers between the component carriers (frequencies), adjacent to each other, aligned in a situation where the components of the bearing adjacent to each other, are distributed in the frequency domain. In addition, Fig shows an example of generating a signal using multiple units of inverse fast Fourier transform (IFFT)as components of the carrier frequencies are not adjacent to each other in a situation where the components of the carrier frequencies are in the frequency domain is not continuous.

[0021] Cluster multiple access frequency division on the same carrier (clustered SC-FDMA) can easily expand the extension of the discrete Fourier transform (DFT) traditional multiple access frequency division on single-carrier (SC-FDMA) and frequency configuration display subcarriers inverse fast Fourier transform (IFFT), because the configuration of the relationship between the discrete Fourier transform (DFT) and inverse fast Fourier transform (IFFT) is one-to-one relationship when using the inverse fast Fourier transform (IFFT), the number of which is equal to an arbitrary number of discrete Fourier transform (DFT). When atomiclearning multiple access frequency division on the same carrier (clustered SC-FDMA) can be represented as NxSC-FDMA or NxDFT-s-OFDMA, and he can inclusively be called segmented multiple access frequency division on the same carrier (segmented SC-FDMA) in accordance with the present invention.

[0022] figure 9 presents a process diagram of the signal processing in the segmented SC-FDMA. According to Fig.9 segmented SC-FDMA can be characterized by the process of the discrete Fourier transform (DFT) using the group setting by way of combining all modulated in the time domain symbols into N groups (N is an integer greater than 1) to alleviate conditions match the properties of a single carrier frequency.

[0023] figure 10 shows a diagram for describing processing of signals for transmitting a reference signal (RS) in the uplink channel (UL). As shown in Figure 10, the data is transferred as follows. First of all, the signal is generated in the time domain, is converted by pre-coding with discrete Fourier transform (DFT), is displayed in frequency and then transmitted using inverse fast Fourier transform (IFFT). In addition, the reference signal (RS) is directly generated in the frequency domain and with the exception of step input at the pre-coding with discrete Fourier transform (DFT) (step S11), sequentially fed to the lo phase is Lisovenko display (step S12), phase inverse fast Fourier transform (IFFT) (step S13) and the step of attaching a cyclic prefix (CP) (step S14) and then passed.

[0024] figure 11 shows a diagram of the structure of Subhadra for RS transmission signal in the case of normal cyclic prefix (CP). On Fig shows a diagram of the structure of Subhadra for RS transmission signal in the case of an extended cyclic prefix (extended CP). In accordance with 11 reference signal (RS signal) is transmitted to the 4th OFDM-symbol and 11th OFDM-symbol. In accordance with Fig reference signal (RS signal) is transmitted to the 3rd OFDM-symbol and the 9th OFDM-symbol.

[0025] in Addition, the structure of the processing shared upstream channel (UL) as a transport channel can be described as follows. On Fig presents a block diagram of a process for processing a transport channel for the shared upstream channel (UL). In accordance with Fig after cyclic control redundancy check (CRC) for the transport block (TB) is attached to the transport unit, intended for transmission in the uplink channel (UL) [130], information in the form of data, which is multiplexed with control information, is divided into multiple code blocks (hereinafter referred to as SW) in accordance with the size of the transport block (TB), and cyclic control redundancy check (CRC) code for the block is (SV) is then attached to each of the multiple code blocks (CB) [131]. Next, channel coding is performed on the corresponding result value [132]. In addition, after performing speed negotiation over subjected to encoding data [133] code blocks (CB) are combined together [set s134]. The combined code blocks (CB) then multiplexed with information about the quality of the channel/index matrix pre-coding (CQI/PMI) [135].

[0026] the information about the quality of the channel/index matrix pre-coding (CQI/PMI) is a coding channel separate from the data [136]. Subjected to encoding information about the quality of the channel/index matrix pre-coding (CQI/PMI) and then is multiplexed with the data [135].

[0027] the indication of rank RI (rank indication) is a coding channel separate from the data [137].

[0028] the Acknowledgement/non-acknowledgment (ACK/NACK) is a coding channel separately from the data quality information channel/index matrix pre-coding (CQI/PMI) and display rank (RI) [138]. Multiplexed data and information about the quality of the channel/index matrix pre-coding (CQI/PMI), separately subjected to channel coding indication of rank (RI) and separately subjected to channel coding of the ACK/not acknowledge received (ACK/NACK) experience the fast channel interleaving to generate the output signal [139].

[0029] In the following description will explain a physical item [hereinafter referred to as a resource element, abbreviated to (RE)] for data and control channel in the uplink communication system for long-term development(LTE). On Fig shows a diagram for describing how to display the physical resources for transmitting uplink data communications channel (UL) and the control channel.

[0030] As shown in Fig, information about the quality of the channel/index matrix pre-coding (CQI/PMI) and the data is displayed on the resource element (RE) by the time of the first circuit. The encoded acknowledgement/non-acknowledgment (ACK/NACK) is placed around the reference signal demodulation (DM RS) using punching. Indicator rank (RI) represents a consensus parameter to the resource element, which is an acknowledgement/non-acknowledgment (ACK/NACK). Resources for indicator RI and receiving acknowledgement/no acknowledgement reception (ACK/NACK) can take a maximum of 4 SC-FDMA symbol.

[0031] As mentioned in the description above, this may be enough to match the properties of a single carrier frequency by multiplexing data with such control information of the upward communication channel (UL control information is control information UCI), as information about the qualities of the channel/index matrix pre-coding (CQI/PMI) and similar information. Thus, it can be enough to transmit upstream communications channel, which caters to a small volume (CM).

[0032] In the system (for example, the system of long-term development (e.g., LTE Rel-10)), the resulting improvement of the current system, at least one transmission scheme selected from a system with multiple access frequency division on single-carrier (SC-FDMA) and systems with clustered multiple access orthogonal frequency division (clustered OFDMA) with discrete Fourier transform (DFT)can be applied to each component of the carrier frequency of the user equipment to transmit upstream communications channel (UL) and can be used together with the transfer on the rising communication channel (UL) via multiple transmitting antennas and multiple receiving antennas (UL-MIMO).

[0033] regarding the structure of the transmission bottom-up link (UL) method of multiplexing data and control information of the upward communication channel (UCI) with each other together when passing through multiple transmitting antennas and multiple receiving antennas (UL-MIMO) has so far not been discussed.

EXAMPLES of carrying out the INVENTION

[0064] embodiments of the present invention are supported by the standards documents, uncovered in at least one of wireless access systems including IEEE 802.16m standard (Institute of electrical engineers and electronics), system Partnership project 3GPP systems of the 3rd generation, the system of Long-term development of systems 3GPP (3GPP LTE/LTE-A) and the 3GPP2 system. In particular, operations or components that are not required to describe technical idea of the present invention in embodiments implementing the present invention can be confirmed by the above-mentioned documents.

[0065] in Addition, in the following description provides specific terminology, to assist in understanding the present invention. The use of special terminology can be changed n the other terms within the scope of technical idea of the present invention.

[0066] In the following description explains the method efficient multiplexing of data and control channel on a shared channel of the uplink communication (UL) by maintaining the properties of a single carrier frequency and compatibility with the existing system and apparatus for carrying out the method in accordance with the present invention.

[0067] On Fig shows the block diagram of a method of efficient multiplexing of data and control channel simultaneously on the ascending line (UL) in accordance with the present invention.

[0068] As shown in Fig, the user equipment recognizes grade for physical data shared upstream channel (UL) channel (PUSCH) [step S150]. Next, the user equipment sets the rank of the control channel of the upward communication channel (UL) (i.e., the control channel can mean a rising control information of the upward communication channel (UL) (abbreviated UCI), as an indication of channel quality (CQI), the acknowledgement/non-acknowledgment (ACK/NACK)indicator rank (RI) and similar information) is same as the rank data [step S151]. Next, the user equipment multiplexes the data and control information with each other (step S152]. Next, after the data and the indicator of channel quality (CQI) on each other is through the time the first circuit, can be made channel interleaving to facilitate the display of the indicator rank (RI) assigned to a resource element (RE) and to facilitate the display of the confirmation of acceptance/lack of acknowledgment (ACK/NACK) through the perforation of the resource element in the vicinity of a reference signal demodulation (DM-RS) [step S153].

[0069] After that, the data and control channel can be modulated by one of the modulation schemes: QPSK, 16QAM, 64QAM and similar modulation scheme in accordance with the table of modulation and coding (MCS) [step S154]. In this implementation, the phase modulation can be moved to another position (for example, a modulating unit can be shifted before the step of multiplexing data and control channel). Channel interleaving may be performed through a block of code words or block levels.

[0070] As mentioned in the foregoing description, if the rank of the control channel limit to have the same rank as the rank of the data, this can provide several advantages from the point of view of overhead on the system. If the data and the control channel are different from each other by rank, then the reference signal demodulation of the upward communication channel (UL) (UL DM RS) will be subjected to pre-coding by the same pre-coding of data. So the WMD additional alarm indicator matrix pre-coding (PMI) may be required for the control channel. The same indicator rank (RI) for both data and control channel can simplify the chain of multiplexing and may be useful for removal of additional signaling. Although there is one effective grade for the control channel transmitted grade control channel may be the rank of the data. From the point of view of the stage of acceptance after applying the decoder multiple transmitting antennas and multiple receiving antennas (MIMO) to each level, each output of the logarithmic likelihood ratio (LLR) can be accumulated by combining maximum ratio (MRC, maximum ratio combining). In this case, the logarithmic likelihood ratio (LLR) can mean the output signal of the device opposite the display modulation PSK/QAM (phase shift keying/quadrature amplitude modulation) and may indicate a logarithmic operation probability that indicates whether the corresponding bit to 0 or 1.

For example, a logarithmic likelihood ratio (LLR) can be determined by Formula 1.

[0071] [Formula 1]

LLR(bI,k)=logP[bI,k=1|r[i] ]P[bI,k=0|r[i]]

[0072] the Present invention does not put any restrictions on the data multiplexing and channel management. In particular, the same above-mentioned principle can be applied in the case of multiplexing time division (TDM) data and control channel.

[0073] the Present invention will be described hereinafter in more detail.

[0074] For clarity and convenience, the following description will assume 2 code words for data. Although limited data directly 2 code words for clarity, the following description that the number of code words is not limited. In particular, the present invention is referred to in the following description may be equally applicable to at least two or more code words. In addition, the present invention is referred to in the following description may be equally applicable for the code word. For example, if there are the first codeword and the second codeword, the present invention can be applied only to the first code word.

[0075] On Fig presents the block diagram for describing the method of generating system is of signal data and control channel in accordance with the present invention. On Fig the position of each block can be changed in accordance with the scheme implementation.

[0076] on the Basis of two code words, the channel coding can be performed for each of the two code words [160] and matching the transmission speed can then be carried out in accordance with the specified table of modulation and coding (MCS) [161]. After that, the coded bits may scribblenauts through a scheme designed for the particular cell, a specific user equipment (UE) or a certain code words [162].

[0077] Next, may be the display of code words on the levels [163]. When performing this process may include the operation of the offset or displacement levels.

[0078] On Fig presents a diagram for describing how to display code words on the levels. Display code words on the levels can be performed using standard shown in Fig. On Fig the location of the pre-coding may be different from the location of the former (pre-coding depicted in Fig.

[0079] Such control information as the indication of channel quality (CQI), indicator rank (RI) and an acknowledgement/non-acknowledgment (ACK/NACK)may be subjected to channel coding in accordance with this description [165]. When implementing the AI that each of the governors of information: the quality indicator channel (CQI), indicator rank (RI) and an acknowledgement/non-acknowledgment (ACK/NACK)may be encoded using the same channel code for all code words or may be encoded using different channel codes in a code word.

[0080] Further, the number of coded bits can be changed through the control unit size bits [166]. The control unit of bit sizes can be combined with unit 165 encoding channel. The signal coming from the output of the control block size bits can scribblenauts [167]. When performing the scrambling may be performed separately for cells, separately for levels, separately for code words or separately for user equipment (UE).

[0081] the control Unit of bit sizes may work as follows.

[0082] (1) the control Unit detects rank (n_rank_pusch) data for physical shared upstream channel (PUSCH).

[0083] (2) Grade (n_rank_control) the control channel is set equal to the rank of the data (i.e., n_rank_control=n_rank_pusch). The number of bits for the control channel is increased by multiplying the rank of the control channel.

[0084] One way to accomplish this may simply include the copy phase and repetition of the control channel. In this case, the control channel may correspond to the information level is prior to channel coding or bit level, encoded after channel coding.
