BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission signal allocation and signaling method in a wireless communication system. In particular, the present invention relates to a Single Code Word Multiple Input Multiple Output (SCW-MIMO) and a Hybrid Automatic Repetition Request (HARQ) using an asynchronous ACK / NACK detection scheme. ACK / NACK (Positive Acknowledgment / Negative Acknowledgement) corresponding to a single codeword (hereinafter referred to as SCW) or multiple code words (hereinafter referred to as MCW) in a wireless communication system supporting MCW-MIMO (Multi Code Word-MIMO) technique Channel assignment and implicit signaling.

HARQ combines Forward Error Correction (FEC) and ARQ (Automatic Repeat reQuest) techniques, which are typical transmission error control technologies in data transmission systems. Basically, error correction is attempted on the encoded received data (hereinafter, referred to as HARQ packet) and a simple error detection code such as a cyclic redundancy check (CRC) is used to determine whether to request retransmission request of the HARQ packet. The HARQ positive acknowledgment (hereinafter, referred to as ACK) signal or the HARQ negative acknowledgment (hereinafter, referred to as NACK) signal is transmitted to the transmitter according to whether an error exists for the received HARQ packet. The transmitter performs a retransmission request or a new HARQ packet transmission of the HARQ packet according to the HARQ ACK / NACK signal.

In an orthogonal frequency division multiplexing (OFDM) based wireless communication system, the ACK / NACK information is carried by a plurality of subcarriers. In general, in one transmission time interval (hereinafter referred to as TTI) for packet data, since HARQ packets for multiple users are transmitted at the same time, ACK / NACK signals for the HARQ packets are also simultaneously transmitted.

Meanwhile, a multi-antenna technique (hereinafter referred to as MIMO technique) is applied as a method useful for high-speed data transmission in a wireless channel in a wireless communication system. As a representative example, EUTRA, which is the next generation mobile communication technology standard of the asynchronous cellular mobile communication standard organization 3GPP, also specifies the application of the MIMO scheme for the OFDMA-based downlink. The MIMO scheme is divided into SCW-MIMO or MCW-MIMO according to whether one or more codewords are transmitted. Here, the codeword means a data set that is independently decoded, and the above-described HARQ packet may also be regarded as a codeword. Each codeword needs to perform an HARQ process in association with a corresponding ACK / NACK channel, so that an ACK / NACK channel is required as many as the number of transmission codewords.

When the base station allocates an uplink ACK / NACK channel corresponding to each codeword every TTI and signals the terminal explicitly, only a required number of ACK / NACK channels are allocated. The UE transmits the ACK / NACK signal through the ACK / NACK channel resource notified by the base station for the downlink data channel, and the UE transmits the ACK / NACK signal from the base station at the ACK / NACK channel resource location signaled by the base station for the uplink data channel. Detects a NACK signal. As mentioned above, when the base station explicitly signals ACK / NACK channel resource allocation to the UE at every TTI, the amount of resources required for signaling that informs the UE of ACK / NACK channel resource information, that is, signaling overhead ), The resource consumption is severe. As a method for overcoming this, uplink ACK / NACK channel resource allocation without separate signaling by mapping the downlink channel resource index allocated from the base station to each terminal to the uplink ACK / NACK channel resource index according to a predefined rule between base station terminals. Implicit signaling is used to allow this to be performed.

In general, the amount of downlink resources that can be used in the system is limited and the downlink resources are allocated to data channels and control channels. For example, FIG. 1 illustrates an OFDM-based downlink frame structure of EUTRA (Enhanced Universal Terrestrial Radio Access), which is the next generation mobile communication technology standard of 3rd Generation Partnership Project (3GPP).

Referring to FIG. 1, the system bandwidth 100 is 10 MHz, and there are 50 resource blocks (RBs) 101 in total within the bandwidth 100. One RB 101 is composed of 12 subcarriers 102, each of which has one or more data channels transmitting seven OFDM symbol intervals 103 (without description) for each user's codeword. It may consist of a number of RBs. In the downlink frame structure of FIG. 1, up to 50 downlink data channels may be simultaneously scheduled in the 1 ms TTI 104. In this case, up to 50 ACK / NACK channels are required in the uplink, but the number of data channels scheduled simultaneously in one TTI is about 10 to 20 on average, so a corresponding number of uplink ACK / NACK channels are required. .

2 is a diagram illustrating an example of a mapping structure of a downlink control channel used for EUTRA. Referring to FIG. 2, six control channel elements 200 constitute one control channel 201 and are assigned (what) in the first three OFDMA symbol periods of a subframe, that is, in the control channel region. . The terminal monitors the control channel candidate group 203 composed of 11 control channel candidates 202 implicitly informed from the base station, and attempts blind decoding for detecting control information. The mapping of the control channel element to the resource element is performed according to a pre-defined rule between the base station and the terminal using the remaining resources except for the subcarrier symbol to which the common pilot is allocated in FIG. 2.

3 shows an example of an ACK / NACK channel allocation and implicit signaling structure for an SCW and two MCWs in a synchronous ACK / NACK detection environment in EUTRA. In the method illustrated in FIG. 3, Resource # 1 302 is used among K resources capable of transmitting ACK / NACK with respect to the first index RB # 1 301 of the RB 300 allocated to the corresponding user M during downlink data transmission. Implicit ACK / NACK channel assignment signaling is used, which gives a one-to-one mapping relationship. Accordingly, the user M looks at the downlink RB index allocated to the user M and transmits an uplink ACK / NACK signal through the corresponding ACK / NACK channel resource. The ACK / NACK channel resource index means an index of a communication resource used for ACK / NACK transmission, and may be different depending on system decisions such as an offset index or subcarrier index of an orthogonal code. In addition, 1-bit ACK / NACK (303) is transmitted by using BPSK (Binary Phase Shift Keying) symbol when SCW transmission, and 2-bit ACK / NACK (304) by applying quadrature phase shift keying (QPSK) symbol when two codewords are transmitted. Send it. Therefore, the receiver determines whether the ACK / NACK for each codeword after performing the synchronous detection for the ACK / NACK symbols, and if the number of transmitted codewords increases, the number of bits per ACK / NACK transmission symbol increases.

In the synchronous ACK / NACK detection method used in FIG. 3, when the accuracy of channel estimation cannot be guaranteed, the synchronous ACK / NACK detection reliability is drastically degraded and the transmission efficiency is reduced because pilot transmission for channel estimation is involved. On the other hand, since the asynchronous ACK / NACK detection method does not require a separate channel estimation, it does not suffer from degradation of detection performance due to channel estimation error and does not suffer a reduction in transmission efficiency due to pilot transmission. In general, since the asynchronous ACK / NACK channel is divided by transmission resources, an increase in allocated resources is required in proportion to the number of ACK / NACK channels.

In an environment using a HARQ transmission scheme using MIMO and asynchronous ACK / NACK detection, a concrete scheme for applying implicit ACK / NACK channel resource allocation signaling to ACK / NACK channel resources required in proportion to the number of transmission codewords This is required.

Accordingly, an object of the present invention is to provide a transmission codeword in an asynchronous ACK / NACK detection environment by providing a base station transmission signal allocation rule according to whether or not to transmit MCW in a wireless communication system using a HARQ transmission scheme using MIMO and asynchronous ACK / NACK detection scheme. The present invention provides a method and apparatus for enabling implicit ACK / NACK channel resource allocation signaling for ACK / NACK channel resources required in proportion to the number.

Another object of the present invention is to provide an implicit signaling method of uplink ACK / NACK channel allocation information, a base station, and a terminal transmitting / receiving apparatus supporting both downlink SCW and MCW transmission modes by appropriately using the above rule of the present invention. .

Hereinafter will be described with reference to the accompanying drawings in accordance with an embodiment of the present invention. Specific details are set forth in the following description, which is provided to aid a more general understanding of the invention. Those skilled in the art will recognize that the disclosed concept and specific embodiments of the invention described below may be changed or modified to achieve the technical problem to be achieved by the present invention. Those skilled in the art will also recognize that concepts and structures equivalent to the concepts and structures disclosed herein do not depart from the spirit and scope of the broadest form of the invention. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention provides an uplink ACK / NACK channel resource allocation and implicit signaling method supporting both downlink SCW and MCW transmission modes in a wireless communication system using HARQ and MIMO schemes using asynchronous ACK / NACK detection. . The present invention also provides a base station signal transmission allocation principle for performing the method.

The present invention corresponds to at least the number of codewords transmitted by the base station to the receiving terminal at the time of MCW transmission in consideration of an increase in transmission data due to high speed data transmission and an increase in transmission control information due to the use of multiple antennas. The downlink data channel RB or the downlink control channel CE is allocated. If two ACK / NACK channels are allocated to two codewords, if the base station assigns only one downlink RB or CE to the user, the same uplink ACK is assigned to the two ACK / NACK channels using the corresponding index. / NACK maps to a transmission resource. As described above, in this situation, it is impossible to distinguish the asynchronous ACK / NACK signal. That is, since the number of ACK / NACK channels required for asynchronous ACK / NACK detection is the same as the number of transmission MCWs, the number of downlink RBs or channel elements to be mapped to the uplink ACK / NACK channel resource index is also at least as large as the number of MCWs transmitted. Must be assigned. As a result, the base station transmission signal allocation principle of the present invention allows the number of RB indexes or channel element indexes to be mapped to multiple ACK / NACK channel resource indexes to be maintained at least above the required level.

Receiving UE notified of the SCW / MCW-related information and downlink resource allocation information from the base station identifies the downlink resource index assigned to the base station and ACK / NACK channel resource index and downlink based on a predetermined rule between the base station and the terminal. Map the allocation resource index. The terminal transmits a single ACK / NACK signal or a plurality of ACK / NACK signals in uplink using mapped ACK / NACK channel resources. Accordingly, the present invention efficiently supports uplink ACK / NACK channel resource allocation and implicit signaling supporting both downlink SCW and MCW transmission modes when asynchronous ACK / NACK is detected.

Hereinafter, exemplary embodiments of the present invention will be described under the assumption of an EUTRA system. The present invention is not limited to the below-described EUTRA system and embodiments, and is applicable to an OFDM-based system using an asynchronous ACK / MACK detection HARQ and MIMO technique. In addition, the first embodiment of the present invention described later specifies that it is applicable to downlink ACK / NACK transmission through some modifications. In addition, the mapping relationship between the downlink channel resource index and the uplink ACK / NACK channel resource index in the present invention covers all possible combinations and is not limited to the mapping method of the following embodiments.

Next, an example of an uplink ACK / NACK allocation and an implicit signaling structure according to the first embodiment of the present invention will be described with reference to FIG. 4. 4 illustrates an example of a mapping relationship between downlink data channel RB allocation resources and uplink ACK / NACK channel resource indexes when SCWs and 2 MCWs are transmitted under EUTRA system assumption with 10 MHz downlink transmission bandwidth. As described above, since the ACK / NACK signal is assumed to use OSK (please specify a full name), the ACK / NACK channel resource is regarded as a shift value of an orthogonal code.

Referring to FIG. 4, the base station 400 allocates downlink transmission resources for each terminal. At this time, the base station is equipped with multiple antennas for the MIMO scheme, and determines whether the MCW of the signal transmitted to each terminal.

If the single code word (SCW) mode transmission (401), the base station transmits a signal through the RB # 0 (403) scheduled to the corresponding terminal of the downlink RB (402) and the receiving terminal is assigned to itself Identify the RB index. The terminal transmits an ACK / NACK signal by using an orthogonal code transition index 406 one-to-one correspondence with the RB index allocated to itself among the orthogonal code transition index set, which is an uplink ACK / NACK channel transmission resource 405. do. In this case, the downlink allocation RB is not necessarily limited to one, and when a plurality of RBs are allocated, mapping is performed between the index of the first RB and the index of the ACK / NACK channel resource. In other words, there is no lower limit for the number of allocated RBs.

On the other hand, when using the 2 MCW mode 407 in which the base station transmits two codewords to the terminal, the base station limits the minimum allocated RB lower limit by scheduling a transmission signal for the terminal to at least two RBs. Through this, two ACK / NACK channel resource indexes and a number of RBs corresponding to one to one are maintained. In the present embodiment, it is assumed that a transmission signal is scheduled to two RBs of RB # 0 403 and RB # 1 408. The receiving terminal transmits two uplink ACK / NACK signals by using two orthogonal code transition indices 405 and 409 respectively corresponding to the two RB indexes 404. This embodiment shows that the ACK / NACK transmission for the MCW is stably performed even when the asynchronous ACK / NACK is applied by applying the principle of the base station scheduling RB according to whether the MCW is transmitted. Through this, the SCW transmission mode and the MCW transmission mode are described. All can be supported. The index mapping in the above description is not necessarily in an index order, and various combinations are possible.

5 is a diagram illustrating an apparatus for transmitting a base station according to the first embodiment of the present invention. In FIG. 5, a dotted line means a control signal, and a solid line indicates an actual data flow. The number of code word sector 500 of the base station determines whether to transmit SCW or MCW for each user. The codeword number selector 500 operates a code word generator 1 501 that performs bit generation, channel encoding, interleaving, and modulation during SCW transmission and generates another codeword. 2 (Code Word generator 2) 502 stops. If 2 MCW is transmitted, the codeword number selector 500 operates both codeword generators 501 and 502 to generate two codewords. The generated codeword is assigned to the RB by a resource mapper 504 via a serial / parallel converter (S / P) 503. At this time, the resource mapper 505 changes the mapping rule according to the SCW / MCW mode signaling of the codeword number selector 500. When the resource mapper 505 is not in the MCW transmission mode, the resource mapper 505 allocates the number of mapped RBs. However, the resource mapper 505 must allocate resources for the UE to at least two RBs during the MCW transmission. When the resource mapping is completed according to the above principle, it passes through an inverse fast fourier transform (IFFT) 506 and a parallel / serial converter 507 and passes through a cyclic prefix inserter 507. The final transmitted signal is transmitted using single or multiple transmit antennas. Although not shown in the figure, the IFFT 506, the bottle / serial converter 507, and the CP inserter 508 constitute a wireless signal processor.

6 is a diagram illustrating a terminal receiver according to a first embodiment of the present invention. The receiving terminal includes a wireless signal processor (not shown in the drawing), which is composed of a CP remover 600, a serial / parallel converter 601, and a fast fourier transform (FFT) 602. The resource index identifier 603 of the terminal identifies the RB index allocated to the terminal in the FFT output signal. One-to-One Mapping (605) 605 maps the resource index to transmit the uplink ACK / NACK channel according to a predetermined rule between the base station using the identified RB index. Based on the mapping result, the ACK / NACK channel allocator 606 allocates the ACK / NACK signal of the terminal to the mapped ACK / NCAK channel resource index.

7 is a flowchart illustrating an operation procedure of a base station according to the first embodiment of the present invention.

Referring to FIG. 7, the base station determines whether to perform SCW transmission or 2 MCW transmission to the target terminal in step 710. As a result of the determination of step 710, when determining the SCW transmission, the base station generates one code word in step 720, and allocates the code word to the RB in step 730. On the contrary, as a result of the determination of step 710, the base station generates two codewords in step 740 and allocates the generated codewords to at least two RBs in step 750. After the transmission mode determination, the codeword generation and the resource allocation according to the transmission mode are performed, the base station performs a final downlink transmission in step 760.

8 is a flowchart illustrating an operation procedure of a terminal according to the first embodiment of the present invention. The receiving terminal receives the SCW / MCW transmission mode and downlink RB information allocated to itself through a BCH (Broadcast Channel) or other L1 control channel from the base station to complete the pre-identification step 810. In step 820, the terminal checks whether the MCW is transmitted based on the identification result. As a result of the check in step 820, in the case of SCW transmission, the receiving terminal performs a one-to-one correspondence between the downlink allocation resources and the ACK / NACK channel resources according to a predetermined rule between the base station and the terminal in step 830. In step 830, the terminal transmits its ACK / NACK using an ACK / NACK channel resource having an index corresponding to the downlink RB. On the contrary, in the determination result of step 820, in case of MCW transmission, the UE maps two indices among downlink RBs allocated to the two ACK / NACK channel resource indexes according to a predetermined rule between the base station and the UE in step 840, respectively. do. Thereafter, in step 850, the UE transmits two ACk / NACK signals for two code words using two ACK / NACK channel resources having indexes corresponding to two downlink RB indexes. Since the MCW transmission assumes high speed data transmission, the RB allocated to the data transmission is also more likely to be increased than the SCW transmission. Therefore, the present invention applies the principle that the base station allocates at least two RBs during MCW transmission in consideration of both the data transmission amount and the implicit signaling of the ACK / NACK channel resource.

Next, a second embodiment of the present invention will be described. FIG. 9 illustrates an example of a mapping relationship between a channel element allocation resource index of a downlink control channel and an uplink ACK / NACK channel resource index when transmitting SCWs and 2 MCWs. Referring to FIG. 9, when the base station 900 is in the SCW transmission mode 901, the receiving terminal receives the CE # assigned to itself among the indexes 901 of the channel elements (CEs) constituting the downlink control channel. After identifying 0903, one-to-one mapping 904 between the index and orthogonal code transition index 906 is performed. In addition, in the MCW transmission mode 907, the base station allocates at least two control channels CE for the user. In this embodiment, this is shown as CE # 0 (903), CE # 1 (908). The receiving terminal performs one-to-one mapping 904 between the indexes of the two channel elements and the orthogonal code transition indexes 906 and 909 according to a predetermined rule between the base station and the terminal. MCW transmission presupposes multi-antenna transmission, and since it involves an increase in control information related thereto, using one channel element is insufficient in consideration of the amount of transmission control information. Therefore, the present invention applies the principle that the base station allocates at least two channel elements during MCW transmission. The base station and terminal transmission and reception structures and operation procedures of the present embodiment are almost the same as described above in the first embodiment, and thus will be omitted.

As described above, the present invention enables implicit signaling of a mapping between a plurality of ACK / NACK channel resource indexes and a plurality of RB or channel element indexes, which is proportional to the number of transmission code words in asynchronous ACK / NACK detection. It efficiently supports increasing ACK / NACK channel resource allocation and implicit signaling.
