Hybrid automatic repeat-request confirms the transmission method and terminal of response message

Technical field

The present invention relates to wireless communication technology, more particularly to a kind of hybrid automatic repeat-request to confirm (HARQ-ACK) response The transmission method and terminal of information.

Background technology

Long Term Evolution (Long Term Evolution, referred to as LTE) system and senior long term evolution (LTE- Advanced, referred to as LTE-A) radio frames (radio frame) in system include FDD (Frequency Division Duplex, referred to as FDD) pattern and time division duplex (Time Division Duplex, referred to as TDD) pattern Frame structure.

Fig. 1 is the schematic diagram of the frame structure in the LTE/LTE-A FDD systems according to correlation technique, as shown in figure 1, one The radio frames of 10 milliseconds (ms) are 0.5ms by 20 length, and the time slot (slot) of numbering 0~19 forms, time slot 2i and 2i+1 Form the subframe (subframe) that length is 1ms.

Fig. 2 is the schematic diagram of the frame structure in the LTE/LTE-A TDD systems according to correlation technique, as shown in Fig. 2 one 10ms radio frames are made up of two a length of 5ms field (half frame), and a field includes the son that 5 length are 1ms Frame, subframe i are defined as 2 a length of 0.5ms time slot 2i and 2i+1.The uplink-downlink configuration supported in TDD system is as shown in table 1.

The uplink-downlink configuration that the TDD system of table 1 is supported

Wherein, to each subframe in a radio frames, " D " represents to be exclusively used in the subframe of downlink transfer, and " U " represents special In the subframe of uplink, " S " represents special subframe, its include descending pilot frequency time slot (Downlink Pilot Time Slot, Referred to as DwPTS), protection interval (Guard Period, referred to as GP) and uplink pilot time slot (Uplink Pilot Time Slot, referred to as UpPTS) three parts.

TDD supports 5ms and 10ms up-downgoing switching cycle.If the downstream-to-upstream transfer point cycle is 5ms, special son Frame can be present in two fields；If downstream-to-upstream transfer point cycle 10ms, special subframe exists only in first field In.Subframe 0 and subframe 5 and DwPTS are always used for downlink transfer.UpPTS and it is exclusively used in immediately following the subframe after special subframe Uplink.

The down mixing self-retransmission request of LTE system (Hybrid Automatic Repeat Request, is referred to as HARQ in), when terminal (User Equipment, referred to as UE) does not have Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH) transmission when, Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH) hybrid automatic repeat-request confirm (Hybrid Automatic Repeat Request Acknowledge, referred to as HARQ-ACK) response message is physically row control channel (Physical Uplink Control Channel, referred to as PUCCH) on transmit, otherwise transmitted on PUSCH.

In LTE TDD systems, because ascending-descending subframes are not one-to-one, that is to say, that multiple descending sub frames HARQ-ACK response messages need to send on the PUCCH channels of a sub-frame of uplink, descending son wherein corresponding to sub-frame of uplink Frame set constitutes feedback window.The sending method of HARQ-ACK response messages has two kinds：One kind is to bind (bundling), the party The core concept of method is the HARQ-ACK responses transmission block corresponding to each descending sub frame for needing to feed back in the sub-frame of uplink Message carries out logic and operation, if a descending sub frame has 2 transmission blocks, UE will feed back the HARQ-ACK responses letter of 2 bits Breath, if each subframe only has a transmission block, UE will feed back the HARQ-ACK response messages of 1 bit；Another kind is multiplexing (multiplexing), this method refers mainly to PUCCH format 1b combined channels selection (PUCCH format 1b in LTE With channel selection) method, the core concept of this method is to utilize on different PUCCH channels and the channel not With modulation symbol come represent need the sub-frame of uplink feedback descending sub frame different feedback states, if on descending sub frame There are multiple transmission blocks, then the HARQ-ACK for first feeding back multiple streams of code words of descending sub frame carries out spatial logic with (being also referred to as Spatial domain bind) after carry out Channel assignment again, then using PUCCH format 1b send.Wherein, bind in window (on namely Row subframe needs the descending sub frame set fed back) HARQ-ACK (i) response messages and the PUCCH channels of selection of each descending sub frame And the relation between the dibit information sent is referred to as the mapping table of Channel assignment, the size for the binding window that existing protocol defines For 2,3,4 when mapping table difference it is as shown in the table, wherein M represent binding window size.
