Description

The present invention relates to the field of communications, and in particular to a method and apparatus for processing a correct/error response message. BACKGROUND In a Hybrid Automatic Repeat Request (HARQ) mode, a codeword sent by a transmitting end can not only detect errors but also have a certain error correction capability. After receiving the codeword, the receiver decoder first checks the error condition. If the error correction capability of the codeword is within, the error correction is automatically performed. If there are many errors, the error correction capability of the codeword is exceeded, but the error can be detected. Then, the receiving end sends a decision signal to the sending end through the feedback channel, and requests the originating end to resend the information. In the Orthogonal Frequency Division Multiplex (OFDM) system, the correct/error response (Acknowledged/Non-acknowledged, ACK/NACK) message is used to indicate the correct/error of the transmission. Whether you need to retransmit. In a Long Term Evolution (LTE) system, an ACK/NACK response message may be sent separately on a Physical Uplink Control Channel (PUCCH) or a physical uplink shared channel (Physical Uplink). Shared Channel, referred to as PUSCH) is sent with the data. In a frequency division duplex (FDD) system, since the uplink and downlink subframes are corresponding, when the physical downlink shared channel (PDSCH) contains only one codeword stream, A User Equipment (UE) is to feed back a 1-bit ACK/NACK response message. When the PDSCH contains two codeword streams, the UE needs to feed back a 2-bit ACK/NACK response message. When the UE does not have a PUSCH in the current subframe. To transmit, the UE will transmit the 1/2-bit ACK/NACK response message on the PUCCH in the format la/lb; and when the UE has PUSCH transmission in the current subframe, the UE will use the 1/2-bit information. After a certain ACK/NACK state to the corresponding bit mapping, the channel coding, scrambling, and modulation are multiplexed with the data, and then transmitted on the PUSCH. In a Time Division Duplex (TDD) system, the uplink/downlink subframes are not—corresponding, that is, the ACK/NACK response messages corresponding to multiple downlink subframes need to be in one uplink subframe PUCCH/ Transmitted on the PUSCH channel, where the downlink subframe corresponding to the uplink subframe is set Formed a binding window ( bundling window ). In LTE TDD, the transmission of two ACK/NACK response messages is defined. This will be explained separately below. One is an ACK/NACK bundling method, and the basic idea of the method is to perform logical AND operations on ACK/NACK messages of codeword streams corresponding to respective downlink subframes that are fed back in the uplink subframe. If the PDSCH transmission of one downlink subframe includes 2 codeword streams, the UE feeds back a 2-bit ACK/NACK response message corresponding to each codeword stream that has passed through the subframe logic and operation, if the PDSCH of each subframe The transmission has only one codeword stream, and the UE feeds back a 1-bit ACK/NACK response message corresponding to the codeword stream after the subframe logic and operation. When the UE does not transmit the PUSCH in the current subframe, the UE will The PUCCH uses the format la/lb to transmit the 1/2-bit ACK/NACK response message; and when the UE has the PUSCH transmission in the current subframe, the UE passes the 1/2-bit information through a certain channel coding. The channel interleaving is multiplexed with the data and then transmitted on the PUSCH. The other is an ACK/NACK multiplexing (ACK/NACK multiplexing) method, which needs to feed back an ACK/NACK response message for each downlink subframe, and multiple subframes need to feed back multiple ACK/NACK response messages, and When a PDSCH transmission of a downlink subframe includes two codeword streams, the ACK/NACK response message of each codeword stream is first logically ANDed, and finally each downlink subframe corresponds to only one ACK/NACK response message. When the UE does not have a PUSCH to transmit in the current subframe, the UE will send the multiple ACK/NACK response messages by using the format lb with channel selection on the PUCCH. The core idea of the method is Different ACK/NACK response messages are represented by different PUCCHs and different modulation symbols on the channel. The method enables a portable ACK/NACK response message to be up to 4 bits by channel selection in combination with the control channel format lb.

Whether the UE uses ACK/NACK bundling or ACK/NACK multiplexing to feed back ACK/NACK is configured by the upper layer. In order to meet the advanced international telecommunications alliance (International Telecommunication

The requirements of Union-Advanced (referred to as ITU-Advanced), the Long Term Evolution Advanced (LTE-A) system, which is the evolution standard of LTE, needs to support larger system bandwidth (up to 100MHz), and Need to be backward compatible with existing LTE standards. Based on the existing LTE system, the bandwidth of the LTE system can be combined to obtain a larger bandwidth. This technology is called Carrier Aggregation (CA) technology, which can improve the IMT-Advance system. The spectrum utilization, mitigation of spectrum resources shortage, and optimize the utilization of spectrum resources. When the LTE-A uses the carrier aggregation technology, when the base station configures multiple downlink component carriers for the UE, the UE needs to feed back the ACK/NACK response messages of the corresponding codeword streams of the multiple downlink component carriers. In LTE-A, when an ACK/NACK response message is sent on the physical uplink control channel, two feedback methods are defined: PU PUCCH format lb (format lb) joint channel selection (Format lb with channel selection), and based on A feedback method for DFT-s-OFDM. In the related art, although the PUCCH format lb can be used for feedback, a specific feedback method is not disclosed, that is, an idea that the PUCCH format lb can be used for feedback is pointed out in the related art, and there is no specific achieve. In addition, in the related art, when feedback is performed in the manner of PUCCH format lb joint channel selection, there is currently no solution for its corresponding mapping table design.

Here, the state of the correct/error response message of the downlink component carrier corresponding to the PUCCH for transmitting the PUCCH format lb may be referred to as non-DTX. When the terminal only detects the primary downlink component carrier or the cell, the terminal uses the PUCCH format la or lb to feed back the ACK/NACK response message in the PUCCH corresponding to the primary downlink component carrier or the cell;

For example, the downlink component carrier or the cell configured for the terminal is 2, and the transmission modes of the two downlink component carriers or cells are required. In the case of feeding back a correct error response message, the correct error response message of the primary downlink component carrier or the cell corresponds to ^d, and the correct error response message of the secondary downlink component carrier (or cell) corresponds to ^HAR Q - ^ACK ( ¹ ); The downlink component carrier or cell configured by the terminal is

2, and the transmission mode of one of the downlink component carriers or the cell needs to feed back two correct error response messages, and when the transmission mode of another downlink component carrier (or cell) needs to feed back one correct error response message, two correct feedbacks are needed. The two correct error response messages of the downlink component carrier of the error response message correspond to ^-HW and ^-HW, and the correct error response message of the downlink component carrier that needs to feed back one correct error response message corresponds to ^HARQ - ^ACK(2) ; When the downlink component carrier or the cell configured for the terminal is 2 and the transmission modes of the two component carriers or the cell need to feed back two correct error response messages, the two correct error response messages of the primary downlink component carrier or the cell correspond to HARQ_ACK (0). And 3⁄4Re_H(l), the auxiliary downlink component carrier or the 2 correct error response messages of the cell correspond to magic Q - ^A CK (2) and HARQ - ACK (3). The following describes the design principles that the above mapping relationship and state combination are satisfied. It should be noted that the following principles can be combined freely or fully. The design principles are described separately below.原贝' J 1: When the number of ACKs in CX(0), 4Wg-CX(l),...,4Wg-CX(Ml)} is N ( 0<N<M ), then It distinguishes whether the remaining (MN) correct error response messages are in NACK or DTX state, that is, the NACK and DTX states of other ACK/NACK response messages are combined. Principle 2: When {HARQ- ACK (0), HARQ- ACK (1), ..., HARQ- ACK (M -1)} If the number is ₀ in _{the ACK,} if the terminal is properly on the primary downlink component carrier The PDCCH is detected, and the corresponding PDSCH detection error (feedback is NACK), the terminal feeds back the corresponding ^f , HARQ-AC, leg Q-AC, ..., leg Q-ACK on the PUCCH channel corresponding to the PDCCH of the primary component carrier. M - ; If the terminal does not correctly detect the PDCCH on the primary component carrier, the terminal does not send any signal to the base station. Principle 3: When the configured downlink component carrier (or cell) is 2 and the transmission mode of two component carriers (or cells) needs to feed back a correct error response message, the correct error response message of the primary downlink component carrier (or cell) Corresponding to HARQ-ACK (0), the correct error response message of the secondary downlink component carrier (or cell) corresponds to HARQ-ACK (1); when the configured downlink component carrier (or cell) is 2 and its The transmission mode of one component carrier (or cell) needs to feed back two correct error response messages. When the transmission mode of another component carrier (or cell) needs to feed back one correct error response message, two correct error response messages need to be fed back. The two correct error response messages of the component carriers correspond to HARQ-ACK(O) and HARQ-ACK(l), and the correct error response message of the component carrier that needs to feed back one correct error response message corresponds to HARQ-ACK(2) When the configured downlink component carrier (or cell) is 2 and the transmission modes of the two component carriers (or cells) need to feed back 2 correct error response messages, 2 correct error response messages of the primary downlink component carrier (or cell) Corresponding to HARQ-ACK(O) and HARQ-ACK(1), the two correct error response messages of the secondary downlink component carrier (or cell) correspond to HARQ-ACK (2) and HARQ-ACK (3). Principle 4: When the terminal only detects the primary downlink component carrier, the terminal will use the PUCCH format la or lb to feed back the PUCCH channel corresponding to the primary downlink component carrier (or cell). Principle 5: For a downlink component carrier configured to feed back two correct error response messages, if the current subframe detects the corresponding PDSCH transmission on only one codeword stream, the correct error response message corresponding to the PDSCH transmission is mapped to The first HARQ-ACK of the two HARQ-ACKs corresponding to the component carrier, and another HARQ-ACK corresponding to the component carrier is set to NACK or DTX. Principle 6: When the constellation points corresponding to (b0, bl) are adjacent, only one of the corresponding correct error response messages is different. In addition to the above principles, one principle to be followed is: The available PUCCH channel is what the UE should be able to obtain, that is, according to the implicitly received or passed between the physically received physical downlink control channel and the PUCCH channel index. The manner of the command is obtained, that is, the ACK/NACK response message of the downlink component carrier corresponding to the PUCCH channel is in a non-DTX state.
