By above method, the disclosure, which can determine not being triggered according to DCI, carries out the PDSCH triggering of HARQ-ACK feedback Group.

In a kind of possible embodiment, the DCI can also include that PDSCH scheduling group identification field and PDSCH are triggered Group identification field.

The disclosure to the size of PDSCH scheduling group identification field and PDSCH triggering group identification field (including number of bits) no It limits, those skilled in the art, which can according to need, is set (such as setting by high-level signaling).

In a kind of possible embodiment, when using Arabic numerals with the form numbered to PDSCH scheduling group, In the case that PDSCH triggering group is identified, the size of PDSCH scheduling group identification field and PDSCH triggering group identification field can root It is determined according to following formula:Wherein, B is the ratio that PDSCH scheduling group identification field and PDSCH triggering group identification field include Special number, N are the number of PDSCH group.That is, the size of PDSCH scheduling group identification field and PDSCH triggering group identification field can pass through Following methods obtain: obtaining the logarithm of the number N of PDSCH group the bottom of for 2, then round up, obtain to the logarithm of acquisition The size B of PDSCH scheduling group identification field and PDSCH triggering group identification field.Certainly, although the disclosure by take it is upper it is whole for carry out Illustrate, it is to be understood, however, that in other implementations, it can also be by the way of removing whole wait to pair of acquisition Number is handled, obtain PDSCH scheduling group identification field and PDSCH triggering group identification field size (for example,)。

Certainly, in other implementations, the size of PDSCH scheduling group identification field and PDSCH triggering group identification field It can be determined according to other modes, how the disclosure is to determining the big of PDSCH scheduling group identification field and PDSCH triggering group identification field Small mode is without limitation.

In a kind of possible embodiment, step S130 is determined in the PDSCH triggering group according to the DCI and is not touched Hair carries out the PDSCH triggering group of HARQ-ACK feedback, may include:

It determines not being triggered according to the identification information of the identification information of PDSCH triggering group, PDSCH scheduling group and carries out HARQ- The PDSCH triggering group of ACK feedback can carry out exemplary retouch to a variety of possible implementations below there are many implementation It states.

In a kind of possible embodiment, according in the PDSCH triggering group identification field identification information with it is described Identification information in PDSCH scheduling group identification field, which determines not to be triggered, carries out the PDSCH triggering group of HARQ-ACK feedback, can wrap It includes:

In an example it is assumed that the identification information in PDSCH scheduling group identification field be 0 (or be number be 0, group number For 0), while the identification information in PDSCH triggering group identification field is also 0, then it was determined that PDSCH triggering group be not triggered into Row HARQ-ACK feedback, in such a case, it is possible to be determined using the 2nd domain DAI of PDSCH triggering group (such as number is 1) The DAI of PDSCH scheduling group.

Certainly, in another case, when the identification information and PDSCH triggering group mark in PDSCH scheduling group identification field (for example, the identification information in PDSCH scheduling group identification field is 1, PDSCH triggering group in the case where identification information difference in domain Identification information in identification field is 0), then it was determined that the PDSCH triggering group that identification information is 0 is triggered and carries out HARQ-ACK Feedback, therefore, in this case, the 2nd domain DAI can serve to indicate that the DAI of PDSCH triggering group, and the first domain DAI can be used In the DAI of instruction PDSCH scheduling group.

In a kind of possible embodiment, the DCI can also include feedback instructions field, and the feedback instructions field can be with It is used to indicate and HARQ-ACK feedback is carried out to target PDSCH group.

In a kind of possible embodiment, the identification information and institute according in the PDSCH triggering group identification field It states identification information in PDSCH scheduling group identification field and determines not to be triggered and carry out the PDSCH triggering group of HARQ-ACK feedback, it can be with Include:

It is described to be triggered according to the instruction information of the feedback instructions field, the PDSCH in a kind of possible embodiment Identification information in group identification field and the identification information in the PDSCH scheduling group identification field determine not to be triggered and carry out HARQ- ACK feedback PDSCH triggering group, may include:

In one example, feedback instructions field may include 1 bit, when feedback instructions field instruction information be 1 (or 0) when, it can determine that DCI carries out HARQ-ACK feedback only for PDSCH scheduling group, in such a case, it is possible to which PDSCH is touched The 2nd DAI (can be one, or more than two) of hair group is used to indicate the DAI of PDSCH scheduling group.Conversely, when feedback instruction When the instruction information in domain is 0 (or 1), it can determine that DCI is applied not only to scheduling PDSCH scheduling group and carries out HARQ-ACK feedback, also HARQ-ACK feedback (can be one, be also possible to two or more) is carried out for dispatching PDSCH triggering group.

In this case, the instruction information in feedback instructions field, which can serve to indicate that, is instructed to carry out HARQ-ACK feedback PDSCH group number.

In this illustration, when indicating information is 0, it is anti-can to indicate that DCI indicates that a PDSCH group carries out HARQ-ACK Feedback, that is, specified PDSCH scheduling group carries out HARQ-ACK feedback, and PDSCH triggering group is not triggered that carry out HARQ-ACK anti- Feedback.

When indicating information is 1, it can indicate that DCI indicates all PDSCH groups progress HARQ-ACK feedbacks (including one PDSCH scheduling group and one or more PDSCH triggering group).

In one example, feedback instructions field may include more than two bits, each bit can with it is each PDSCH group corresponds to, and each bit that DCI can use in feedback instructions field indicates whether that dispatching corresponding PDSCH group carries out HARQ-ACK feedback.

For example, feedback instructions field may include 3 bits, indicate respectively PDSCH scheduling group, PDSCH triggering group 1, Whether PDSCH triggering group 2 carries out HARQ-ACK feedback, it is assumed that 0 indicates to feed back without HARQ-ACK, and 1 indicates to carry out HARQ- ACK feedback, then it is 111 that feedback instructions field, which can be set, to indicate PDSCH scheduling group, PDSCH triggering group 1, PDSCH triggering Group 2 all carries out HARQ-ACK feedback, and in this case, PDSCH scheduling group, PDSCH triggering group 1, PDSCH triggering group 2 are respective The domain DAI be used to indicate respective DAI；Or,

It is 101 that feedback instructions field, which can be set, to indicate that PDSCH scheduling group, PDSCH triggering group 2 carry out HARQ-ACK Feedback, PDSCH triggering group 1 are fed back without HARQ-ACK, and in this case, the 2nd domain DAI of PDSCH triggering group 2 can be with With the first DAI of the PDSCH scheduling group and DAI of joint instructions PDSCH scheduling group, the 2nd DAI of PDSCH triggering group 1 can be used In the DAI of instruction PDSCH triggering group 1；Or,

It is 100 that feedback instructions field, which can be set, to indicate that PDSCH scheduling group carries out HARQ-ACK feedback, PDSCH triggering Group 1 and PDSCH triggering group 2 is fed back without HARQ-ACK, and in this case, the 2nd domain DAI of PDSCH triggering group 1/2 can With the DAI of the first DAI and joint instructions PDSCH scheduling group with PDSCH scheduling group.

Certainly, above description is exemplary, and is not considered as the limitation to the disclosure.

In a kind of possible embodiment, the feedback instructions field is also used to indicate to be used to indicate progress HARQ-ACK anti- The number of the PDSCH triggering group of feedback carries out HARQ-ACK feedback to indicate that how many PDSCH triggering group is triggered.

The identification information according in the feedback instruction information of instructions field, the PDSCH triggering group identification field and Identification information in the PDSCH scheduling group identification field, which determines not to be triggered, carries out the PDSCH triggering group of HARQ-ACK feedback, also May include:

The PDSCH triggering group for not being instructed to carry out HARQ-ACK feedback in the PDSCH triggering group identification field is determined as It is not triggered and carries out the PDSCH triggering group of HARQ-ACK feedback.In one example, feedback instructions field may include 2 bits Position.

Feedback instructions field can be set to 00, and having 0 PDSCH triggering group to be triggered with instruction, to carry out HARQ-ACK anti- Feedback.In this case, the 2nd domain DAI of each PDSCH triggering group may be used to indicate the DAI of PDSCH scheduling group.

Feedback instructions field can be set to 01, and having 1 PDSCH triggering group to be triggered with instruction, to carry out HARQ-ACK anti- Feedback.In this case, in addition to 1 PDSCH triggering group being instructed to, the 2nd DAI of other PDSCH triggering groups is ok It is used to indicate PDSCH scheduling group DAI.

DCI can only indicate to be triggered in feedback instructions field carries out the number of the PDSCH triggering group of HARQ-ACK feedback, HARQ-ACK feedback is carried out without specifically indicating which PDSCH triggering group is triggered, in this case, user equipment can be with Judge which PDSCH triggering group is triggered according to preset rules (such as agreement regulation) and carries out HARQ-ACK feedback.

In a kind of possible embodiment, user equipment can determine to be triggered according to the sequence of number carries out HARQ- The PDSCH triggering group of ACK feedback.

Assuming that the number of PDSCH scheduling group is 0, HARQ-ACK feedback is carried out when feedback instructions field instruction is triggered In the case that the number of PDSCH triggering group is 1 (feedback instructions field is 01), user equipment can increase or reduce according to number Sequence determine PDSCH triggering group.For example, user equipment, which can determine to be triggered, carries out the PDSCH triggering of HARQ-ACK feedback Group is the PDSCH group 1 (according to increased sequence is numbered) that number is 1, in such a case, it is possible to be 2 and number using number The DAI of PDSCH scheduling group is indicated for 3 PDSCH group 2, the 2nd domain DAI of PDSCH group 3.

Alternatively, can determine be triggered carry out HARQ-ACK feedback PDSCH triggering group be number be 3 PDSCH group 3 (according to the sequence of number reduction, it is assumed that total PDSCH group number is 4, is determined by the way of group circulation in this example, i.e., The previous group of PDSCH group 0 is PDSCH group 3).In such a case, it is possible to using number be 1 and number be 2 PDSCH group 1, The DAI of the 2nd domain the DAI instruction PDSCH scheduling group of PDSCH group 2.

It is to be understood that above description is exemplary, it is not construed as the limitation to the disclosure, is implemented in others In mode, increase according to number, the sequence of reduction determines when being triggered the PDSCH triggering group for carrying out HARQ-ACK feedback, increase, The step-length of reduction can be 2, or other (preceding example step-length is 1), alternatively, can also be determined using other modes The PDSCH triggering group that HARQ-ACK feedback Chu Fa not carried out, in this regard, the disclosure is without limitation.

Feedback instructions field can be set to 10, and having 2 PDSCH triggering groups to be triggered with instruction, to carry out HARQ-ACK anti- Feedback.

When feedback instructions field instruction, which there are 2 PDSCH triggering groups to be triggered, carries out HARQ-ACK feedback, touched according to PDSCH The number determination of hair group is the method for which PDSCH triggering group, the description before please referring to.

Example in undertaking, it is assumed that the number of PDSCH scheduling group is 0, and in one example, user equipment can be determined and is triggered The triggering group for carrying out HARQ-ACK feedback be that (number is 1 and numbers to be 2, increased according to number for PDSCH group 1 and PDSCH group 2 Sequentially).In such a case, it is possible to which the 2nd domain DAI of the PDSCH triggering group for being 3 using number indicates PDSCH scheduling group DAI。

Feedback instructions field also can be set to 11, and having 3 PDSCH triggering groups to be triggered with instruction, to carry out HARQ-ACK anti- Feedback.

In this example, as it is assumed that the number of total PDSCH group is 4, when there are three PDSCH for the instruction of feedback instructions field Triggering group is triggered carry out HARQ-ACK feedback in the case where, then merely with PDSCH scheduling group the first domain DAI indicate PDSCH The 2nd domain DAI of the DAI of scheduling group, other PDSCH triggering groups are used to indicate respective DAI.
