To make the object, technical solutions and advantages of the present invention clearer, right below in conjunction with the accompanying drawings and the specific embodiments The present invention is described in detail.

The some concepts being previously mentioned in the embodiment of the present invention are described as follows first.

At present in NR communication system, HARQ-ACK feedback is supported to use semi-static code book scheme.

When using semi-static code book scheme to user configuration, it is necessary first to determine that feedback window a M, M are defined as base In high-level signaling configuration minimum and maximum data to feed back between slot time and high-level signaling be allocated to UE (User Equipment, user equipment, also referred to as terminal) multiple data to the slot time value between feedback, UE can determine M For DCI (Downlink Control Information, Downlink Control Information) format 1_0 or DCI format 1_1 transmission PDCCH detection machine meeting, it is corresponding in the same PUCCH (Physical Uplink Control Channel, physical uplink control Channel) or PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) feedback HARQ-ACK.

When generating feedback code book, increased sequence can be indexed to every according to PDCCH detection machine after first carrier index increase Each PDCCH detection machine on one carrier wave can generate corresponding feedback bits, and detailed process is as follows:

Merge if carrier wave is configured HARQ-ACK without using space, is fed back without using the HARQ-ACK based on CBG, and work as Preceding carrier wave is configured for needing to receive two transmission blocks, then generates the feedback information of 1 bit respectively to each transmission block, to working as The preceding current PDCCH detection machine of carrier wave can the raw 2 bit feedback information of common property；

If carrier wave is configured the merging of HARQ-ACK use space, fed back without using the HARQ-ACK based on CBG, and current Carrier wave is configured for needing to receive two transmission blocks, then carries out logical AND operation to the feedback information of 1 bit of two transmission blocks, The feedback information of raw 1 bit of PDCCH detection machine meeting common property current to current carrier, if terminal only receives a transmission block, Assuming that the corresponding feedback information of second transmission block is ACK；

It is fed back if carrier wave is configured such that with the HARQ-ACK based on CBG, and current carrier is configured to need to receive one Transmission block, then the feedback information of the raw X bit of PDCCH detection machine meeting common property current to current carrier, X are that high-level signaling configures carrier wave On the maximum CBG number that uses.

The present invention determines scheme for existing semi-static feedback code book, and there is no consider in a PDCCH detection machine meeting In, it may transmit more than one for dispatching the downlink data transmission of different length in different time-gap or same time slot The problem of the case where PDCCH leads to the semi-static feedback code book generated inaccuracy, influences system transmission performance provides a kind of anti- Feedback code book determines method and device.

As shown in Fig. 2, the feedback code book of the embodiment of the present invention determines method, comprising:

Step 21, first transmitted in the physical downlink control channel PDCCH detection machine meeting of a carrier wave is obtained PDCCH quantity；

It should be noted that the first PDCCH quantity refers to transmit in the one PDCCH detection machine meeting of a carrier wave Maximum PDCCH number.

Step 22, according to the first PDCCH quantity, determine that the target of the PDCCH detection machine meeting of a carrier wave is anti- The length of feedforward information；

It should be noted that the length of the object feedback information is specially the bit number of object feedback information.

Step 23, according to the length of the object feedback information, feedback codebook information is determined.

The length of object feedback information is being obtained, the determination of feedback information is carried out, is obtaining final feedback codebook information, is being needed It is noted that the feedback code book determines that method can be applied to terminal, base station also can be applied to, i.e., terminal is according to the feedback Code book determines that method generates feedback codebook information, and is sent to base station, and base station determines that method determines eventually according to the feedback code book The feedback codebook information sent is held, and receives the feedback codebook information in corresponding position.

It should be noted that step 21 mode can be realized one of in the following way:

Mode one, the control information resources set number that will be configured in a PDCCH detection machine meeting of a carrier wave determine For the first PDCCH quantity；

Mode two will all control the use configured in information resources set in a PDCCH detection machine meeting of a carrier wave Need to carry out the sum of the search space number of PDCCH of mixed automatic retransfer response message (HARQ-ACK) feedback in transmission, really It is set to the first PDCCH quantity；

Mode three will all control the need configured in information resources set in a PDCCH detection machine meeting of a carrier wave The sum of the corresponding PDCCH candidate collection number in search space for carrying out HARQ-ACK feedback, is determined as the first PDCCH quantity；

It should be noted that the search space for needing to carry out HARQ-ACK feedback described in such implementation is corresponding PDCCH is by Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) or semi-persistent scheduling radio network temporary identifier (SPS-RNTI) It is scrambled.

Mode four will all control the control for including in information resources set in a PDCCH detection machine meeting of a carrier wave The sum of Channel Elements (CCE) number processed, is determined as the first PDCCH quantity；

Mode five obtains the predefined first PDCCH quantity of agreement；

It should be noted that in this way, the first PDCCH quantity is predefined in communication protocol standard, terminal or base Standing can directly acquire to obtain.

Mode six obtains the first PDCCH quantity that base station is configured by high-level signaling；

It should be noted that passing through high-level signaling (for example, wireless heterogeneous networks by base station in the first PDCCH quantity (RRC) signaling) when being allocated to terminal, the first PDCCH quantity be more than or equal to 1 and be less than or equal to 4 integer.

Mode seven understands the period according to PDCCH detection machine, determines the first PDCCH quantity.

Specifically, which seven mode can be realized one of in the following way:

Mode A1, PDCCH detection machine can be determined as the first PDCCH quantity in the period；

Under such implementation, the first PDCCH quantity is just equal to PDCCH detection machine can the period.For example, on a carrier wave PDCCH detection machine can the period be 2 time slots, then illustrate that there are a PDCCH detection machine meetings in every 2 time slots, in order to guarantee Downlink transfer in all time slots can be scheduled, then enable the first PDCCH quantity transmitted in a PDCCH detection machine meeting (i.e. maximum PDCCH number) is 2.

Mode A2, the Physical Downlink Shared Channel configured according to PDCCH detection machine meeting period and wireless heterogeneous networks (RRC) (PDSCH) resource allocation information determines the first PDCCH quantity；

Under such implementation, the first PDCCH quantity can period and RRC configuration PDSCH resource point by PDCCH detection machine It is determined with information, more preferably, the first PDCCH quantity is not to be overlapped in the maximum time domain that can be transmitted in the PDCCH detection machine meeting period PDSCH number, such as detection machine can the period be 1 time slot, but RRC configuration PDSCH resource allocation information in indicate The minimum length of PDSCH transmission is 7 orthogonal frequency division multiplexing (OFDM) symbols, then time slot is (it should be noted that at one Gap includes 14 OFDM symbols) at most transmit two PDSCH, then enable PDCCH detection machine can in the first PDCCH that transmits Quantity is 2.

Further, the specific implementation of step 22 are as follows:

Further, the specific implementation of step 23 are as follows:

Specifically, it is determined that a carrier wave a PDCCH detection machine can in each PDCCH feedback information implementation Including one in following implementation:

Mode B1, when carrier wave do not configure the HARQ-ACK based on CBG feedback when, a bit is determined to each transmission block The corresponding feedback information of at least one transmission block is cascaded each PDCCH by feedback information according to the sequence of transmission block Obtain the corresponding feedback information of PDCCH；

It is that this PDCCH is obtained according to the determination of the feedback information of each transmission block in a PDCCH in such implementation Corresponding feedback information, because each transmission block divides in order, so in cascade, it only need to be suitable according to the division of transmission block Sequence, which is one by one cascaded the corresponding feedback information of transmission block, just obtains the corresponding feedback information of a PDCCH.

Mode B2, when carrier wave be configured with the HARQ-ACK based on CBG feedback when, by the corresponding feedback letter of at least one CBG Breath is cascaded to obtain the corresponding feedback information of transmission block and is transmitted at least one to each PDCCH according to the sequence of CBG The corresponding feedback information of block is cascaded to obtain the corresponding feedback information of PDCCH according to the sequence of transmission block；

In this case, dividing in each transmission block has multiple CBG, because each CBG is divided in order, is carrying out When cascade, the corresponding feedback information of CBG is cascaded one by one according to the stripe sequence of CBG, it is corresponding to obtain each transmission block Then the corresponding feedback information of transmission block is cascaded one by one according still further to the stripe sequence of transmission block and just obtains one by feedback information The corresponding feedback information of a PDCCH.

Mode B3, when carrier wave be configured with the HARQ-ACK based on CBG feedback when, to each CBG cascade two transmission blocks Corresponding feedback information is cascaded the corresponding feedback information of at least one CBG to obtain PDCCH correspondence according to the sequence of CBG Feedback information.

In this case, dividing in each transmission block has multiple CBG, when being cascaded, two transmission blocks are corresponding Feedback information in the corresponding feedback information of CBG of corresponding position cascaded, then, CBG pairs after the completion of will cascade The corresponding feedback information of CBG after the completion of cascade is cascaded one by one according to the stripe sequence of CBG, obtains one by the feedback information answered The corresponding feedback information of a PDCCH.

After obtaining the corresponding feedback information of each PDCCH, a carrier wave can be carried out according to the sequence of PDCCH One PDCCH detection machine can feedback codebook information determination, specifically, the method for determination of the sequence of PDCCH can use with One under type:

If mode C1, the first PDCCH quantity provide for the control information configured in the PDCCH detection machine meeting of a carrier wave Number is gathered in source, according to the identification information of the corresponding control information resources set of PDCCH, determines the sequence of PDCCH；

It should be noted that if the first PDCCH quantity be a carrier wave a PDCCH detection machine can in the control that configures Information resources set number at most transmits a PDCCH in each control information resources set, then resource set according to the control information The identification information of conjunction can determine the sequence of PDCCH, and specifically, the identification information of the control information resources set can be control Information resources set ID.

If mode C2, the first PDCCH quantity are at least one control information in the PDCCH detection machine meeting of a carrier wave Being used for transmission for configuring in resource collection needs to carry out the sum of search space number of the PDCCH of HARQ-ACK feedback, according to The identification information of the corresponding control information resources set of PDCCH and the identification information of search space, determine the sequence of PDCCH；

It should be noted that if the first PDCCH quantity is at least one control in the PDCCH detection machine meeting of a carrier wave Being used for transmission for configuring in information resources set processed needs to carry out the sum of search space number of the PDCCH of HARQ-ACK feedback, A PDCCH is at most transmitted in each search space, then according to the identification information (example of the corresponding control information resources set of PDCCH For example control information resources set ID) and the identification information (for example, search space ID) of search space can determine PDCCH's Sequence, for example, being ranked up within each control information resources set according to the corresponding difference search space ID of PDCCH； Then the PDCCH within multiple control information resources set is carried out according to the sequence of control information resources set ID from small to large Sequence.

If mode C3, the first PDCCH quantity are at least one control information in the PDCCH detection machine meeting of a carrier wave The sum of corresponding PDCCH candidate collection number in the search space for needing to carry out HARQ-ACK feedback configured in resource collection, root According to the corresponding control identification information of information resources set of PDCCH, search space identification information and search space in PDCCH Order of candidates determines the sequence of PDCCH；

For example, determining PDCCH sequence according to the PDCCH order of candidates in search space within each search space； Then it within each control information resources set, is ranked up according to the corresponding difference search space ID of PDCCH；Then right PDCCH within multiple control information resources set is ranked up according to the sequence of control information resources set ID from small to large.

If mode C4, the first PDCCH quantity are at least one control information in the PDCCH detection machine meeting of a carrier wave The sum of CCE number for including in resource collection is believed according to the identification information of the corresponding control information resources set of PDCCH and control The sequence for ceasing the identification information of the CCE in resource collection, determines the sequence of PDCCH；

For example, believing within each control information resources set according to the mark of the CCE in control information resources set Breath (for example, CCE ID) determines PDCCH sequence；Then the PDCCH within multiple control information resources set is believed according to control The sequence of breath resource collection ID from small to large is ranked up.

If the first PDCCH quantity transmitted in the PDCCH detection machine meeting for the carrier wave that mode C5, base station configure is big When 1, according to PDCCH increased in Downlink Control Information (DCI) sort instruction information, according to PDCCH sort instruction information from As low as big sequence determines the sequence of PDCCH；

It should be noted that the bit number of PDCCH sequence instruction information is usually determined by the first PDCCH quantity, I.e.Wherein, A is the first PDCCH quantity.

It should also be noted that, in the length according to the object feedback information, during determining feedback codebook information, If detect that PDCCH number is less than the first PDCCH quantity, the corresponding PDCCH feedback information bit of PDCCH is being not detected Set the feedback information for filling non-response (NACK) or discontinuous transmission (DTX).
