Description

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, abbreviating LTE as) radio frames (Radio Frame) in the system comprises Frequency Division Duplexing (FDD) (Frequency Division Duplex, abbreviate FDD as) frame structure of pattern and time division duplex (Time Division Duplex abbreviates TDD as) pattern.Fig. 1 is according to frame structure schematic diagram in the FDD system of 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, is numbered 0～19 time slot (slot) and forms by 20 length, it is subframe (subframe) i (wherein, 0≤i≤9) of 1ms that time slot 2i and 2i+1 form length.Fig. 2 is according to frame structure schematic diagram in the TDD system of correlation technique, as shown in Figure 2, in the frame structure of tdd mode, the radio frames of a 10ms is longly formed for the field of 5ms (half frame) by two, comprise in the field that 5 length are the subframe of 1ms, subframe i is defined as 2 long combinations for the time slot 2i of 0.5ms and 2i+1 (wherein, 0≤i≤9).

In above-mentioned two kinds of frame structures, adopt standard cyclic prefix (Normal Cyclic Prefix, abbreviate Normal CP as) time, the symbol that to comprise 7 length in time slot be 66.7 microseconds (us), 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 abbreviates Extended CP as), comprise 6 symbols in the 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 " expression is exclusively used in the subframe of downlink transfer; " U " expression is exclusively used in the subframe of uplink; " S " expression is used for DwPTS (Downlink Pilot Time Slot; descending pilot frequency time slot); protection is the special subframe in these three territories of (Guard Period abbreviates GP as) and UpPTS (Uplink PilotTime Slot, uplink pilot time slot) at interval.

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 only is present in first field; Subframe #0 and subframe #5 and DwPTS always are used for downlink transfer; UpPTS and the subframe of closelying follow behind special subframe are exclusively used in uplink.

In the LTE system, PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) is used for bearing downlink control information (Downlink Control Information abbreviates DCI as), comprises: uplink and downlink schedule information and uplink power control information.The form of DCI (DCI format) 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 (Control Channel Element, abbreviate CCE as) be unit, the size of a CCE is 9 resource element groups (Resource Element Group, abbreviate REG as), i.e. 36 resource elements (Resource Element), a PDCCH may take 1,2,4 or 8 CCE.

Embodiment two

Present embodiment provides a kind of confirmation feedback method.Present embodiment combines embodiment one and preferred implementation wherein, and in the present embodiment, the corresponding configuration of a sub-frame of uplink window is a P descending sub frame, and the Serving cell quantity of UE configuration is Q, and the transmission block quantity that descending sub frame i goes up allocating cell j transmission is Z _{I, j}, wherein, P can be 1,2,3,4,9, Q can 1,2,3,4,5, Z _{I, j}Can be 1,2.

Work as P=4, during Q=5, suppose, base station scheduling all PDSCH in the corresponding configuration of sub-frame of uplink window, Fig. 5 is a schematic diagram one of representing sum according to the DAI of the embodiment of the invention, as shown in Figure 5, the DAI of corresponding first descending sub frame is 00, represent that its value is that the DAI of 5, the second descending sub frames is 10, represents that its value is 10, the DAI of the 3rd descending sub frame is 01, represent that its value is that the DAI of 15, the four descending sub frames is 11, represents that its value is 20.

When P was 4, M was 4, and the affirmation information of each subframe correspondence is divided into 1 group, and the affirmation information of every group of correspondence is mapped as 1 information by logical AND, and described information is ACK, NACK, DTX or ACK, NACK.

DAI value that the UE basis receives and the PDSCH quantity that receives are judged the value of the DAI correspondence that receives.

For example: UE detects PDSCH on first descending sub frame be 3, and detected DAI is 00 on first descending sub frame, so, the value that this DAI represents must be 5, can not be 1 or 9 to wait other values, because, as shown in Table 2,00 value corresponding is 1/5/9/13/17 etc., and UE has detected 3, so, just can not be 1, and, giving the PDSCH quantity of UE at most on the subframe is 5, can not be greater than 5, so, can not be 9 to wait other greater than 5 value.

By as can be known top, according to the DAI on first descending sub frame, to send to the PDSCH quantity of UE be 5 in the base station on first descending sub frame, and still, UE only receives 3 PDSCH, has 2 PDSCH to lose, and first descending sub frame correspondence mappings information is NACK.

UE detects PDSCH on second descending sub frame be 2, detected DAI is 10 on second descending sub frame, so, the value that this DAI represents must be 10, can not be 6 or 14 to wait other values, because as shown in Table 2,10 value corresponding are 2/6/10/14/18 etc., UE has known that the PDSCH quantity that sends on first subframe is 5, and detected PDSCH quantity is 2 on second subframe, so, the PDSCH quantity that sends on preceding 2 subframes is necessarily greater than 5+2=7, so the DAI on second descending sub frame can not be 6, and, giving the PDSCH quantity of UE at most on the subframe is 5, two subframes can not be greater than 10, so, can not be 14 to wait other greater than 10 value.

In like manner, according to the DAI on second descending sub frame, as can be known, to send to the PDSCH quantity of UE be 5 in the base station on second descending sub frame, and still, UE only receives 2 PDSCH, has 3 PDSCH to lose, and second descending sub frame correspondence mappings information is NACK.

UE detects PDSCH on the 3rd descending sub frame be 5, detected DAI is 01 on the 3rd descending sub frame, so, the value that this DAI represents must be 15, because, UE has known that it is 10 that preceding two subframes are uploaded defeated PDSCH quantity, it is 5 by detecting PDSCH on the 3rd descending sub frame again, so, the DAI value of the 3rd subframe correspondence must be 15, and the PDSCH quantity that receives on the 3rd descending sub frame is 5, do not have PDSCH to lose, it is an information that the affirmation information of 5 PDSCH is carried out the logical AND operation map.

The logical AND operation is exactly when the affirmation information of all logical AND operations all is ACK, and the result of logical AND operation is ACK, is NACK as long as in the affirmation information of all logical AND operations a confirmation is arranged, and the result of logical AND operation is NACK.

Suppose that corresponding affirmation message all is ACK on the 3rd descending sub frame, then, the information of the 3rd subframe mapping is ACK.

UE detects PDSCH on the 4th descending sub frame be 5, detected DAI is 11 on the 3rd descending sub frame, so, the value that this DAI represents must be 20, because, UE has known that it is 15 that first three subframe is uploaded defeated PDSCH quantity, it is 5 by detecting PDSCH on the 4th descending sub frame again, so, the DAI value of the 4th subframe correspondence must be 20, and the PDSCH quantity that receives on the 3rd descending sub frame is 5, do not have PDSCH to lose, it is an information that the affirmation information of 5 PDSCH is carried out the logical AND operation map;

Suppose that in the corresponding affirmation message confirmation being arranged on the 4th descending sub frame is NACK, then, the information of the 4th subframe mapping is NACK;

The information that UE sends is NACK, NACK, ACK, NACK; Send described information by channel selective mode;

Implement three

When P is 3, M is 4, and the affirmation information of last descending sub frame correspondence is divided into 2 groups, and the affirmation information of main plot correspondence is one group in the described descending sub frame, the affirmation information of auxilliary sub-district correspondence is another group, and the affirmation information of each subframe correspondence is divided into 1 group in the residue descending sub frame; The affirmation information of every group of correspondence is mapped as 1 information by logical AND, and described information is ACK, NACK, DTX or ACK, NACK.

For example: UE does not have to detect the PDSCH that PDCCH is arranged on first descending sub frame, received a PDSCH who does not have the SPS of PDCCH, so, U E does not receive DAI on first descending sub frame, do not know on first descending sub frame to send PDSCH quantity, and to detect PDSCH be 2 to UE on second descending sub frame, detected DAI is 00 on second descending sub frame, so, the value that this DAI represents must be 5, can not be 1 or 9 to wait other values, because, as shown in Table 2,00 value corresponding is 1/5/9/13/17 etc., and UE has known that a PDSCH is arranged on first subframe, and, detected PDSCH quantity is 2 on second subframe, and so, the PDSCH quantity that sends on preceding 2 subframes is necessarily greater than 1+2=3, so, DAI on second descending sub frame can not be 1, and UE can suppose to take place that probability that 4 and 4 above PDCCH lose is very little can not occur, if DAI represents 9, so, be equivalent to have 4 PDCCH to lose, so, can not be 9 to wait other greater than 9 value.

According to the DAI on second descending sub frame, UE as can be known, to send to the PDSCH quantity of UE be 5 in the base station on preceding two descending sub frames, and still, UE only receives 3 PDSCH, there are 2 PDSCH to lose, lose PDSCH and may occur in first descending sub frame, also may occur in second descending sub frame, so, first descending sub frame correspondence mappings information is NACK, and second descending sub frame correspondence mappings information is NACK.

UE detects PDSCH on the 3rd descending sub frame be 3, detected DAI is 11 on the 3rd descending sub frame, so, the value that this DAI represents must be 8, because, UE has known that it is 5 that preceding two subframes are uploaded defeated PDSCH quantity, be 3 by detecting PDSCH on the 3rd descending sub frame again, so, the DAI value of the 3rd subframe correspondence must be 8, and, the PDSCH quantity that receives on the 3rd descending sub frame is 3, does not have PDSCH to lose, and the affirmation information of main plot correspondence is one group, the affirmation information of auxilliary sub-district correspondence is another group, and the affirmation information of each subframe correspondence is divided into 1 group in the residue descending sub frame; With the affirmation information of 3 PDSCH logical AND operation map of dividing into groups is two information.

Suppose that corresponding affirmation message all is ACK on the 3rd descending sub frame, then, the information of the 3rd subframe mapping is ACK, ACK.

The information that UE sends is NACK, NACK, ACK, ACK; Send this information by channel selective mode.
