Method for transmitting acknowledgement/negative acknowledgement and terminal for implementing the same

A right / wrong answer transmission method messages and achieve end FIELD

The present invention relates to the field of communications, in particular, to use carrier aggregation technology, time division duplex system a right / wrong answer (Acknowledgement / Negative Acknowledgement ACK / NACK) message transmission method and implement end of the process. Background technique

In the hybrid automatic repeat request (HybridAutomatic Repeat Request, HARQ) mode, the originator sends a code word, not only error detection, but also have some error correction capability. After the receiver decoder receives the code word, the first test error conditions within the code word error correction capability, automatic error correction, if a lot of errors, more than the code word error correction capability, but it can detect errors , the receiver to send the originator of a decision by a feedback channel signal, retransmission of information requirements originating. In an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplex, OFDM) system, through the correct / error response message to indicate that transmit true / false, in order to determine the need for retransmission.

In the long term evolution (Long Term Evolution, LTE, it corresponds to the standard protocol for the Rel-8/9) system, ACK / NACK acknowledgment message may be sent individually in a physical uplink control channel (Physical Uplink Control Channel, PUCCH) on, and in physical uplink shared channel (physical uplink shared channel, PUSCH) on together with the data sent.

In a frequency division duplex (Frequency Division Duplex, FDD) system, since the uplink and downlink subframes are - correspondence, so when the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) contains only one code word stream, UE to feedback 1-bit ACK / NACK response message when PDSCH comprises two codewords stream, UE to feedback 2-bit ACK / NACK reply message when the UE in the current sub-frame is no PUSCH to be transmitted when, UE will PUCCH on adoption format la / lb to send the 1 or 2-bit ACK / NACK response message; when the UE Current sub-frame has PUSCH transmission, the UE these 1 or 2-bit information, after a certain ACK / NACK state to the corresponding bit mapping, channel coding, scrambling, modulated with the data multiplexed together and then on PUSCH send.

In time division duplex (Time Division Duplex, TDD) system, since uplink and downlink sub-frame is not - correspond, i.e. a plurality of downlink subframes corresponding to the ACK / NACK reply message requires a uplink subframe PUCCH / PUSCH transmitted on the channel, wherein the uplink subframe corresponding downlink subframe collection of bindings window (bundling window). In LTE TDD, the definition of the two ACK / NACK response message feedback modes: ACK / NACK binding (ACK / NACK bundling), shown in Figure 1, the feedback mode basic idea is to require the uplink subframe feedback of each downlink subframe in a code word stream ACK / NACK message is a logical aND operation, if a downlink subframe PDSCH transmission comprises two yards word stream, UE to be fed through a sub-frame logic operation corresponding to each code word stream of 2-bit ACK / NACK reply message, PDSCH transmit if each sub-frame of only one code word stream, UE to be fed through the corresponding sub-frame logic operation in the codeword stream 1 bit ACK / NACK response message when the UE in the current sub-frame is no PUSCH to be transmitted, UE will use the format la / lb on the PUCCH to send the 1 or 2-bit ACK / NACK response message; and when the UE in the current sub frame has PUSCH transmission, the UE these 1 or 2 bits of information, after a certain channel coding, channel interleaving and data multiplexed together and then in the PUSCH transmitted. Another is the ACK / NACK multiplexing (ACK / NACK multiplexing) feedback mode, shown in Figure 2, the feedback mode is required for each downlink subframe feedback an ACK / NACK response message, a plurality of sub-frames is required to feed back multiple ACK / NACK reply message, and when a downlink subframe PDSCH transmission comprises two yards word stream, the first for each codeword stream ACK / NACK reply message logical aND operation, and ultimately each downlink subframe corresponds to only one ACK / NACK reply message. When the UE in the current sub-frame is no PUSCH to be transmitted, UE will use the format lb joint channel selection (format lb with channel selection) manner on the PUCCH to transmit the plurality of ACK / NACK reply message, the core idea of ​​this method is the use of different The PUCCH channel and the channel different modulation symbols to indicate different ACK / NACK reply message. In this method, the channel selection combined control channel format lb way to make the portable ACK / NACK reply message up to four bits. LTE defines the different uplink and downlink sub-frame configuration, i.e. uplink and downlink sub-frame allocation were 1:2 / 3/4 (M = 2/3/4) when ACK / NACK acknowledgment message state combination and selection of PUCCH channels and this channel carries 2-bit information b (0) b (l) between the mapping table (abbreviated mapping table, as described later in the LTE-a mapping table distinguish, where a mapping table may also be referred to as LTE mapping table)

UE using the ACK / NACK bundling or ACK / NACK multiplexing to feedback ACK / NACK configured by higher layers. Later discussion only for ACK / NACK in the PUCCH sent.

In order to meet the advanced ITU (International Telecommunication Union- Advanced, ITU-Advanced) requirements, as the evolution of LTE standard advanced LTE (Long Term Evolution Advanced, LTE-A, which corresponds to the standard protocol for the Rel-10) system the need to support larger system bandwidth (up to 100MHz), and requires backward compatible LTE existing standards. In the existing LTE system, based on may be an LTE system bandwidth combined to obtain greater bandwidth, a technique called Carrier Aggregation (Carrier Aggregation, CA) technology, which can improve the IMT-Advance System Spectrum efficiency, ease of spectrum scarcity of resources, to optimize the spectrum resources.

Carrier aggregation is introduced in a system, the polymerization is called a carrier component carrier (Component Carrier, CC), also referred to as a serving cell (Serving Cell). At the same time, also made the main component carrier / cell (Primary Component Carrier / Cell, PCC / PCell) secondary component carrier / cell (Secondary Component Carrier / Cell, SCC / SCell) concept and, during the carrier aggregation system, contains at least one primary serving cell and secondary serving cell, wherein the main serving cell remains active.

When the LTE-A using carrier aggregation, when the base station is configured with a plurality of downlink services for UE When a cell, UE needs to feed the plurality of downlink serving cell corresponding codeword stream ACK / NACK reply message. In the LTE-A where, when ACK / NACK reply message is sent on a physical uplink control channel, defines two feedback method: PUCCH format lb joint channel selection (Format lb with channel selection) and based on DFT-s-OFDM of feedback. Because based on DFT-s-OFDM feedback manner which channel structure and PUCCH format l / la / lb / 2 / 2a / 2b are different, and therefore in the conventional LTE-A protocol, this structure is referred to PUCCH format 3 ( PUCCH format 3). For configured with multiple serving cell UE, if the UE can only support 4-bit ACK / NACK feedback, then the UE will use the PUCCH format lb joint channel selection mode feedback ACK / NACK; if the UE can support more than 4 bits ACK / NACK feedback, then the base station further by high-level signaling configuration of the UE is using PUCCH format lb joint channel selection mode or using the PUCCH format 3 to feedback ACK / NAC:.

For LTE-A in the PUCCH format lb joint channel selection mode, the current agreement were TDD system and the FDD system defines the different mapping tables, and are different from the LTE mapping table, as shown in Figures 3 to 9, wherein FIG 3 ~ FIG. 5 is a LTE mapping table (corresponding to M = 2, 3, 4), FIG. 6 ~ FIG. 8 is a LTE-a FDD system mapping table (corresponding to a = 2, 3, 4, a to LTE-AFDD carrier aggregation system, configure the total number to the UE serving cell transport block), FIG. 9 is a LTE- a TDD system mapping table.

In an FDD system, when the UE is configured to use PUCCH format 3 mode to feedback ACK / NACK, due to channel resources for transmitting PUCCH format 3 used are based on ACK / NACK resource indicator Scell ​​on (ACK / NACK Resource Indicator, ARI) dynamically indicating UE to use high-level configuration of 4 or 4 pairs (PUCCH format 3 uses transmit diversity time) in which a / p, so when UE received only Pcell the PDSCH when, PUCCH format 3 channel resources not available at this time, the agreement, UE will use the PUCCH format la / lb to feedback their ACK / NAC:. When the UE using PUCCH format lb joint channel selection Way feedback ACK / NACK, since the channel to the selected map in the design when it has been considered if received only primary service area, which send forms such as PUCCH format la / lb. Therefore, the use of PUCCH format lb joint channel selection mode feedback of ACK / NACK UE, its ACK / NACK feedback mode always uses PUCCH format lb joint channel selection, without having to receive only PCell the PDSCH situation, and so special deal with.

In a TDD system, when the UE is configured with only when a serving cell (the LTE Rel-8/9 the same), the base station requires further through a high layer signaling indicating that the UE is using ACK / NACK bundling or the use ACK / NACK multiplexing manner to feedback ACK / NAC:. When the UE configured with multiple serving cell, UE will use PUCCH format lb joint channel selection or PUCCH format 3 to feedback ACK / NAC:. When configured with multiple serving and using PUCCH format 3 to feedback ACK / NACK the UE, when it receives only Pcell the PDSCH when, how feedback ACK / NACK is a serious problem.

In addition, taking into account the introduction of the multi-antenna uplink LTE-A's, PUCCH spatial orthogonal resource transmit diversity (Spatial Orthogonal Resource Transmit Diversity, SORTD) as transmit diversity scheme also provides that different PUCCH formats whether to adopt transmit diversity is stand-alone configuration, ie PUCCH format la / lb and PUCCH format transmit diversity scheme 3 may be different. Therefore, when the PUCCH format 3 transmit diversity scheme and PUCCH format la / lb transmission scheme inconsistent, when receiving only Pcell the PDSCH and the UE will use the PUCCH format la / lb feedback, UE what kind of multi-antenna transmitting scheme feedback ACK / NACK is also a serious problem. SUMMARY
