Confirmation feedback method and terminal

Technical field

The present invention relates to the communications field, in particular to a kind of confirmation feedback method and terminal.

Background technology

Long Term Evolution (Long Term Evolution, referred to as LTE) radio frames (Radio Frame) in system comprises Frequency Division Duplexing (FDD) (Frequency Division Duplex, referred to as FDD) frame structure of pattern and time division duplex (Time Division Duplex, referred to as TDD) pattern.Fig. 1 is frame structure schematic diagram in the FDD system according to correlation technique, as shown in Figure 1, in the frame structure of fdd mode, the radio frames of one 10 milliseconds (ms) is 0.5ms by 20 length, is numbered the time slot of 0 ~ 19 (slot) and forms, time slot 2i and 2i+1 forms subframe (subframe) i (wherein, 0≤i≤9) that length is 1ms.Fig. 2 is frame structure schematic diagram in the TDD system according to correlation technique, as shown in Figure 2, in the frame structure of tdd mode, the radio frames of a 10ms is made up of two long fields (half frame) for 5ms, it is the subframe of 1ms that a field comprises 5 length, subframe i is defined as the combination (wherein, 0≤i≤9) of 2 long time slot 2i and 2i+1 for 0.5ms.

In above-mentioned two kinds of frame structures, adopt standard cyclic prefix (Normal Cyclic Prefix, referred to as Normal CP) time, the symbol that 7 length are 66.7 microseconds (us) is comprised in a time slot, wherein the CP length of first symbol is 5.21us, and the CP length of all the other 6 symbols is 4.69us; When adopting extended cyclic prefix (Extended Cyclic Prefix, referred to as Extended CP), comprise 6 symbols in a time slot, the CP length of each symbol is 16.67us.

The uplink-downlink configuration that each subframe is supported is as shown in table 1.Wherein, " D " represents the subframe being exclusively used in downlink transfer; " U " represents the subframe being exclusively used in uplink; " S " represents for DwPTS (Downlink Pilot Time Slot; descending pilot frequency time slot); the special subframe in protection interval (Guard Period, referred to as GP) and UpPTS (Uplink PilotTime Slot, uplink pilot time slot) these three territories.

The uplink-downlink configuration signal table that each subframe of table 1 is supported

As can be seen from the above table, LTE TDD supports the up-downgoing switching cycle of 5ms and 10ms.If the downstream-to-upstream transfer point cycle is 5ms, special subframe can be present in two fields; If the downstream-to-upstream transfer point cycle is 10ms, special subframe is only present in first field; Subframe #0 and subframe #5 and DwPTS is always for downlink transfer; UpPTS and be exclusively used in uplink immediately following subframe after special subframe.

In LTE system, PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) for bearing downlink control information (Downlink Control Information, referred to as DCI), comprising: uplink and downlink schedule information and uplink power control information.The form (DCI format) of DCI is divided into following several: DCI format 0, DCI format1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format2A, DCI format 3 and DCI format 3A etc.The physical resource of transmission PDCCH is with control channel element (ControlChannel Element, referred to as CCE) be unit, the size of a CCE is 9 resource element group (ResourceElement Group, referred to as REG), i.e. 36 resource elements (Resource Element), a PDCCH may take 1,2,4 or 8 CCE.

In the FDD system of LTE, because ascending-descending subframes is one to one, so as PDSCH (PhysicalDownlink Shared Channel, Physical Downlink Shared Channel) when only comprising a transmission block, UE will feed back the ACK (Acknowledge of 1 bit, correct response)/NACK (Non-Acknowledge, wrong responses) response message; When PDSCH comprises two transmission blocks, UE will feed back the ACK/NACK response message of 2 bits.But in a tdd system, ascending-descending subframes is not one to one, that is the ACK/NACK response message that multiple descending sub frame is corresponding needs PUCCH (the Physical Uplink Control Channel at a sub-frame of uplink, Physical Uplink Control Channel) upper to send, the set of wherein corresponding with sub-frame of uplink multiple descending sub frames constitutes " bundling window (binding window) ".

Therefore, the sending method of ACK/NACK response message has two kinds in a tdd system: one is binding (bundling) method, the core concept of the method is that ACK/NACK response message corresponding for each descending sub frame transmission block needing to feed back at this sub-frame of uplink is carried out logic and operation according to streams of code words index, if wherein comprise 2 transmission blocks at least one descending sub frame, then UE will feed back the ACK/NACK response message of 2 bits, if all comprise a transmission block in each subframe, then UE will feed back the ACK/NACK response message of 1 bit, another kind is Channel assignment (multiplexing with channelselection, be called for short multiplexing) method, the core concept of the method is the different feedback states utilizing different modulation symbol on different PUCCH channels and this channel to represent the descending sub frame that needs feed back at this sub-frame of uplink, if comprise multiple transmission block in descending sub frame, Channel assignment is carried out again after so first the ACK/NACK response message of multiple transmission block feedbacks of this descending sub frame being carried out logical AND (being also called spatial bundling) operation, then PUCCH format1b is used to send, the ACK/NACK information of 4 bits can be transmitted at most.

In order to meet senior International Telecommunication Union (International Telecommunication Union-Advanced, referred to as ITU-Advanced) requirement, as senior Long Term Evolution (the Long Term EvolutionAdvanced of LTE evolution standard, referred to as LTE-A) system needs to support larger system bandwidth (reaching as high as 100MHz), and needs the existing standard of backward compatibility LTE.On the basis of existing LTE system, can obtain larger bandwidth by the bandwidth of LTE system being carried out merging, this technology is called carrier aggregation (Carrier Aggregation, referred to as CA) technology.This technology can improve IMT-Advance system the availability of frequency spectrum, to alleviate frequency spectrum resource in short supply, and then optimizes the utilization of frequency spectrum resource.The LTE system bandwidth of described carrier aggregation can regard component carrier frequency (Component Carrier as, referred to as frequency spectrum), each component carrier frequency also can be called a community (Cell), and that is a frequency spectrum can be polymerized by n component carrier frequency (Cell).A R10 UE (User Equipment, subscriber equipment) resource be made up of n community (component carrier frequency) of frequency domain, wherein, a community is called main plot (Primary cell), and all the other communities are called auxiliary community (Secondary cell).

Sub-frame of uplink can corresponding multiple descending sub frame, and each descending sub frame has multiple community, and Fig. 3 is according to the next sub-frame of uplink of the carrier aggregation scene of correlation technique corresponding downstream arrangements window schematic diagram as shown in Figure 3.Each community can by a transport block transmission according to transmission mode difference, also can by two transport block transmission.In lte-a system, UE needs confirmation (ACK/NACK) information content of feedback can increase at double.
