Description
Technical field
The present invention relates to the communications field, the transmission method and the subscriber equipment of response message under a kind of antenna system in many ways.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system is the essential planning of third generation partnership, Fig. 1 shows the structural representation of basic frame structure in the LTE system, as shown in Figure 1, frame structure is divided into radio frames, field, subframe, time slot and four grades of symbol, wherein, the length of a radio frames is 10ms, a radio frames is made up of two fields, the length of each field is 5ms, and a field is made up of 5 subframes, and the length of each subframe is 1ms, a subframe is made of two time slots, and the length of each time slot is 0.5ms.
When the LTE system adopts the regular circulation prefix, time slot comprise 7 length be 66.7us on/descending symbol, wherein, the circulating prefix-length of first symbol is 5.21us, the circulating prefix-length of other 6 symbols is 4.69us.When the LTE system adopts extended cyclic prefix, time slot comprise 6 length be 66.7us on/descending symbol, wherein, the circulating prefix-length of each symbol is 16.67us.
At the descending HARQ of LTE (Hybrid Automatic Repeat request, hybrid heavily referring to automatically asked) in, as UE (User Equipment, terminal) there is not PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) time, PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) ACK/NACK (Acknowledgement/Negative Acknowledgement, correct/error response message) response message upward sends at PUCCH (Physical Uplink ControlChannel, Physical Uplink Control Channel).
In the LTE system, defined multiple PUCCH format (form), comprise PUCCHformat 1/1a/1b and format 2/2a/2b, wherein format 1 is used for sending SR (the Scheduling Request of UE, dispatch request) signal, format 1a and 1b are used for feeding back the ACK/NACK response message of 1 bit and the ACK/NACK response message of 2 bits respectively, format 2 is used for sending CSI (Channel States Information, channel condition information), comprise: CQI (Channel Quality Information, channel quality information), PMI (Precoding matrix indicator, precoding information) and RI (Rank Indication, rank indication information), format 2a is used for sending the ACK/NACK response message of CSI and 1 bit, and format 2b is used for sending the ACK/NACK response message of CSI information and 2 bits.Wherein, format 2a/2b only is used for the scene that Cyclic Prefix is the regular circulation prefix.
In the LTE system, at FDD (Frequency Division Duplex, frequency division duplex system) in, because ascending-descending subframes is one to one, so when PDSCH only comprises a transmission block, UE need feed back the ACK/NACK response message of 1 bit, and when PDSCH comprised two transmission blocks, UE will feed back the ACK/NACK response message of 2 bits.At TDD (Time Division Duplex, tdd systems) in, because ascending-descending subframes is not one to one, the ACK/NACK response message that is to say a plurality of descending sub frame correspondences need send on the PUCCH of sub-frame of uplink channel, and wherein " bundling window (configuration window) " formed in the set of the descending sub frame of sub-frame of uplink correspondence.Among the TDD, the transmission main method of ACK/NACK response message has two kinds: a kind of bundling of being (binding method), the core concept of this method is carrying out logic and operation in the ACK/NACK response message of the transmission block of each descending sub frame correspondence of this sub-frame of uplink feedback, if a descending sub frame has 2 transmission blocks, UE will feed back the ACK/NACK response message of 2 bits, if each subframe has only a transmission block, UE will feed back the ACK/NACK response message of 1 bit; Another kind is multiplexing (multiplexing with channel selection, channel is selected) method, the core concept of this method be utilize different modulation symbol on different PUCCH channels and this channel to represent need be at the different feedback states of the descending sub frame of this sub-frame of uplink feedback, if a plurality of transmission blocks are arranged on the descending sub frame, the then first ACK/NACK that a plurality of transmission blocks of descending sub frame need be fed back carries out carrying out the channel selection again behind the logical AND (spatial bundling), uses PUCCH format1b to send then.
In order to satisfy (the International TelecommunicationUnion-Advanced of senior International Telecommunications Union, abbreviate ITU-Advanced as) requirement, senior Long Term Evolution (Long Term Evolution Advanced as the evolution standard of LTE, abbreviating LTE-A as) system need support bigger system bandwidth (reaching as high as 100MHz), and need the existing standard of backward compatibility LTE.On the basis of prior LTE system, the bandwidth of LTE system can be merged and obtain bigger bandwidth, this technology is called carrier aggregation (Carrier Aggregation abbreviates CA as) technology.In order to obtain higher peaks spectrum efficient, in the LTE-A system, many transmit antennas of up support, consider that the transmission diversity mode can improve the reliability of Channel Transmission, improve the signal to noise ratio of received signal, therefore, all be based on the transmission diversity mode at the discussion of the defeated pattern of PUCCH channel multi-antenna transmitting, orthogonal space resource transmission diversity (Space Orthogonal-Resource TransmitDiversity, abbreviate SORTD as) be under the multiaerial system, send one of candidate scheme of response message, the principle of SORTD is to use different resources to transmit identical signaling on different antennas, because for the scene of four antennas, the conclusion of this area all obtains by two antennas are virtual at present, so for multiaerial system, as long as determine two resources.
When LTE-A had adopted carrier aggregation technology, when UE had disposed 4 downlink component carriers, UE need feed back the ACK/NACK of these 4 downlink component carriers.If under the MIMO situation, UE need feed back the ACK/NACK of each code word, and then when UE had disposed 4 downlink component carriers, UE need feed back 8 ACK/NACK.Regulation about ACK/NACK response message feedback is at present: if the terminal of LTE-A is supported 4 bit ACK/NACK response message at most, then use channel selecting method; If support feedback greater than 4 bit ACK/NACK response message, can use the method for channel selection, also can use the method for DFT-s-OFDM structure, use which kind of method by the high-level signaling configuration.Under a single aerial system, the principle of the resource allocation methods that channel is selected is: if the PDCCH of PDSCH correspondence is in principal component carrier wave (perhaps main plot), then the resource of PUCCH use is by the implicit mapping of the CCE of PDCCH, otherwise by high level configuration or by ARI (ACK/NACK Resource Indicator replys the resource indication) indication.But system is not given under the multiaerial system at present, when UE adopts the method feeding back ACK that channel selects/NACK response message, the resource that transferring ACK/NACK response message uses, thus the method feeding back ACK/NACK response message that under multiaerial system, can't effectively adopt channel to select made.
Summary of the invention
