Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

In addition, the terms "and/or", only a kind of incidence relation for describing affiliated partner, indicates may exist Three kinds of relationships, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B.Separately Outside, character "/" herein typicallys represent the relationship that forward-backward correlation object is a kind of "or" in the case where not illustrating. In addition, it is necessary to understand, in the description of the embodiment of the present invention, the vocabulary such as " first ", " second " are only used for distinguishing description Purpose is not understood to indicate or imply relative importance, can not be interpreted as indication or suggestion sequence.

Firstly, the relevant technologies and application scenarios of the invention are introduced.

In LTE (Long Term Evolution, long term evolution) wireless communication system, when UE is needed in some subframe PUSCH on send upstream data, and at the same time when needing to send ascending control information (such as ACK/NACK, CQI, PMI, RI), If UE does not support PUCCH's (Physical Uplink Control CHannel, Physical Uplink Control Channel) and PUSCH Simultaneous transmission, then ascending control information will transmit on PUSCH jointly together with data-reusing.

In LTE, due to downlink data transmission and corresponding ACK/NACK (Acknowledgement/Negative ACKnowledgment determines answering/no answering) there are fixed sequential relationship, eNodeB (Evolved Node B, evolution Type Node B) it can know when to receive the ACK/NACK from UE, therefore ACK/NACK and data can be correctly decoded. But have sent the PDCCH for descending scheduling as eNodeB, and when UE is not received, UE can't feeding back ACK/NACK, ENodeB but it is expected to receive ACK/NACK, so as to cause the mismatch of UE coding and eNodeB decoding process.That is, if Whether rate-matched sends dependent on ACK/NACK at this time, then may cause data decoding failure.In order to avoid this mistake, In LTE, HARQ-ACK is mapped on PUSCH always by the mode of punching and is transmitted, thus those bits for not being perforated Information is not influenced by with the presence or absence of ACK/NACK.

But in 5G NR, due to supporting mini-slot (mini-slot) transmission, CBG-based is supported to feed back (Code Block Group based feedback, the feedback based on encoding block group) and the factors such as multi-carrier transmission, HARQ-ACK feedback Bit number may be bigger, if the mode to PUSCH punching is still used to transmit HARQ-ACK, will lead to many of PUSCH Information is all fallen by HARQ-ACK punching, is affected to the transmission performance of PUSCH, therefore can be for 1~2 bit in 5G NR HARQ-ACK using being transmitted to PUSCH mode punch, and the HARQ-ACK for being greater than 2 bits is used and PUSCH rate Matched mode is transmitted.For the PUSCH transmission for thering is UL grant (uplink scheduling instruction) to dispatch, include in UL grant DAI (Downlink Assignment Index, downlink distribution index) information field is used to indicate and transmits on PUSCH HARQ-ACK bit number.

In 5G NR, the PUSCH for also supporting the non-PUSCH by DCI control and being controlled by the DCI not comprising DAI, this Class PUSCH is properly termed as without index PUSCH, such as grant free PUSCH, SPS PUSCH etc..With grant-free For PUSCH transmission, base station does not send any scheduling information to grant-free PUSCH, and only configuring UE by RRC signaling can With carry out grant-free PUSCH transmission position and some configuration informations.UE basis in the preconfigured position in base station is matched Confidence breath carries out grant-free PUSCH transmission.

In 5G NR, downlink data transmission may be fixed sequential relationship either dynamic with corresponding ACK/NACK Determining sequential relationship, if it is the sequential relationship being dynamically determined, base station can be transmitted corresponding by DCI indicating downlink data The feedback position of ACK/NACK, if it is fixed sequential relationship, the feedback position of the corresponding ACK/NACK of downlink data transmission It is predetermined in a standard.

By taking grant-free PUSCH transmission as an example, base station does not send any scheduling information to grant-free PUSCH. If having used fixed sequential relationship and base station scheduled PDSCH transmission and it feeds back the HARQ-ACK that should be greater than 2 bits, And HARQ-ACK feedback and grant free PUSCH transmission be when taking place at the same instant, if UE be not received by it is any PDSCH transmission then only transmits grant free PUSCH.At this moment, base station is not aware that UE is not received by any PDSCH and passes It is defeated, detection HARQ-ACK feedback and grant free PUSCH are removed still according to the mode of rate-matched, base station side is caused to receive Mistake.

The core concept of the embodiment of the present invention is: using when between downlink data transmission and corresponding ACK/NACK transmission When fixed sequential relationship, if existed in system without index PUSCH transmission, delay without index PUSCH when that may transmit The HARQ-ACK of gap feeds back to other ascending time slots that can transmit HARQ-ACK feedback.

In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper Technical solution is stated to be described in detail.

It should be noted that following each embodiments be based on the same inventive concept, it is any understanding or explaining It, can be with reference to content documented by other embodiments when the content of embodiment.

Embodiment one

Referring to Figure 1, the embodiment of the present invention provides a kind of ACK/NACK transmission method, and this method can be used in equipment room ACK/NACK transmission is carried out, such as can be UE and carry out ACK/NACK transmission to base station.Wherein, UE can be PC (PC), notebook, mobile phone, internet of things equipment, wearable device etc., for the concrete type of UE, the embodiment of the present invention With no restrictions.

The process of ACK/NACK transmission method in the embodiment of the present invention is described as follows:

Step 101: the corresponding ACK/NACK institute of descending time slot fed back is determined using fixed sequential relationship The ascending time slot of occupancy.

Step 102: being used for transmission the cordless that cordless draws Physical Uplink Shared Channel PUSCH resource if being configured in radio frames Draw PUSCH ascending time slot, then will be needed according to fixed sequential relationship in the ACK/ without index PUSCH ascending time slot transmission NACK is delayed to the transmission of other ascending time slots in radio frames with preset rules；Wherein, no index PUSCH is non-by downlink control The PUSCH of information DCI control processed, or, the PUSCH controlled by the DCI not comprising downlink distribution index DAI；Other ascending time slots For the ascending time slot in radio frames in addition to without index PUSCH ascending time slot.

It should be noted that time slot described in the embodiment of the present invention can be slot, it is also possible to mini-slot.

In the specific implementation process, it will be needed according to fixed sequential relationship without index PUSCH uplink in step 102 The ACK/NACK of slot transmission, three portions can be divided by being delayed to the transmission of other ascending time slots in radio frames with preset rules Point, it respectively determines feedback slot part, determine delay position part and determines feedback codebook size and feedback resources part.With Under these three parts are illustrated:

First part: feedback slot is determined

In the embodiment of the present invention, in UE access wireless communication system, base station can issue uplink-downlink configuration information to UE With without index PUSCH configuration information.Wherein, the descending time slot and ascending time slot in radio frames are defined in uplink-downlink configuration information, Without index PUSCH configuration information in define be used for transmission in radio frames without index PUSCH without index PUSCH ascending time slot.

UE can determine all ascending time slots in radio frames according to the uplink-downlink configuration information being previously received, according to pre- First receive without index PUSCH configuration information determine be used for transmission in radio frames without index PUSCH without index PUSCH uplink Time slot.In turn, it can determine that the time slot in all ascending time slots in radio frames in addition to without index PUSCH ascending time slot is available In the feedback slot of transmission ACK/NACK.

When being transmitted, the ACK/NACK that UE can will need to postpone is delayed to feedback slot transmission with preset rules, and Base station then can receive the ACK/NACK that need to postpone after postponing in the feedback slot.Wherein, the ACK/NACK that need to postpone is i.e. To be needed according to fixed sequential relationship in the ACK/NACK without index PUSCH ascending time slot transmission.

Second part: delay position is determined

In the embodiment of the present invention, the ACK/NACK that will need to postpone is delayed to the specific of the feedback slot with preset rules Embodiment includes two kinds:

1, time delay shortest delay mode

The ACK/NACK that will need to postpone all is delayed to the former feedback slot in feedback slot with the ACK/NACK that need to postpone It is transmitted on the smallest nearest feedback slot of time interval.

Wherein, former feedback slot is the ascending time slot determined according to fixed sequential relationship, i.e., the ACK/NACK that need to postpone The corresponding ascending time slot before delay.

In transmission, UE can transmit the ACK/NACK that need to all postpone in the nearest feedback slot, and base station can be at this The ACK/NACK that need to all postpone is received on nearest feedback slot.

2, time delay is most short and bit isostatic lag mode

Firstly, according to the number of the descending time slot fed back in the quantity and radio frames of feedback slot in radio frames Amount is determined in each time slot in feedback slot and is divided in a manner of the descending time slot fed back in mean allocation radio frames The quantity for the descending time slot for not needing to feed back, to obtain the setting quantity allotted of each time slot in feedback slot.

In turn, the ACK/NACK that successively delay need to postpone is transmitted into feedback slot, makes each time slot in feedback slot The quantity of the corresponding descending time slot fed back is no more than the setting quantity allotted of itself, and each time slot in feedback slot Original feedback slot time interval corresponding with the ACK/NACK that need to postpone is minimum.

That is, being directed to any ACK/NACK that need to postpone, can be determined in all feedback slots in radio frames The quantity of the descending time slot fed back out be no more than itself setting quantity allotted feedback slot, determine these In feedback slot, the former the smallest feedback slot of feedback slot time interval with the ACK/NACK that need to postpone, as any need Corresponding feedback slot after the ACK/NACK delay of delay.

In the specific implementation process, for any ACK/NACK that need to postpone, can first judge nearest in radio frames The quantity for the descending time slot that feedback slot is fed back whether be more than itself setting quantity allotted feedback slot, such as not It is more than any ACK/NACK that need to postpone then to be delayed to the nearest feedback slot, if being more than, when judging the nearest feedback Whether the quantity for the descending time slot that next feedback slot after gap is fed back is more than itself setting quantity allotted Feedback slot, if not exceeded, any ACK/NACK that need to postpone then is delayed to next feedback slot, if being more than, Continue to judge subsequent feedback slot, it is known that determine that the quantity of the descending time slot fed back is less than itself The feedback slot for setting quantity allotted as this it is any need to postpone ACK/NACK delay after corresponding feedback slot.

In transmission, corresponding feedback slot after the ACK/NACK delay that UE need to can postpone each respectively transmits each need The ACK/NACK of delay；Corresponding feedback slot transmits and each need to postpone after the ACK/NACK delay that base station need to postpone each respectively ACK/NACK receives each ACK/NACK that need to postpone.

That is, base station can successively in each feedback slot each time slot, receive in each ACK/NACK that need to postpone It is not yet carried out in received each ACK/NACK, corresponding original feedback slot and the maximum ACK/ of feedback slot time interval NACK, wherein the quantity that each time slot in each feedback slot carries out received ACK/NACK is no more than setting for each time slot itself Determine quantity allotted.

Part III: feedback codebook size and feedback resources are determined

Determine feedback codebook size:

After the ACK/NACK delay that determination need to postpone when the feedback codebook size of corresponding feedback slot, it is divided into using quiet State codebook size and use dynamic codebook size both of these case:

Situation one: static codebook size is used

When using static codebook size, when any feedback after the ACK/NACK that need to postpone delay in corresponding feedback slot The feedback codebook size of gap is determined that a part is the codebook size of any feedback slot before postponing, another part by two parts For be delayed to any feedback slot ACK/NACK former feedback slot codebook size, this two parts codebook size and i.e. For the feedback codebook size of corresponding any feedback slot after delay.

Situation two: dynamic codebook size is used

When using dynamic codebook size, can be determined according to the total DAI (total downlink distribution index) indicated in DCI is needed The feedback codebook size of corresponding feedback slot after the ACK/NACK delay of delay.

Wherein:

If in total DAI indication feedback window 1, in DCI the descending time slot in need fed back quantity, According to any received in the feedback window of any time slot in corresponding feedback slot after the ACK/NACK delay that need to postpone The total DAI that DCI includes determines the feedback codebook size of any time slot.Wherein, feedback window includes needing same All descending time slots that ascending time slot is fed back.

That is, if in total DAI indication feedback window all scheduling downlink PDSCH slot/mini- Slot number, then comprising that should be dispatched by base station in the corresponding new feedback window of feedback slot after a delay in total DAI All PDSCH slot/mini-slot number, UE assume that base station owns in the corresponding new feedback window of feedback slot after a delay Identical total DAI is indicated in downlink DCI.

By base in feedback window when if the total DAI instruction 2, in DCI is in the descending time slot of the downlink transfer DCI Stand scheduling the descending time slot feed back quantity, then after being postponed according to the ACK/NACK that need to postpone when corresponding feedback The total DAI that the DCI finally received in the feedback window of any time slot in gap includes, determines any time slot Feed back codebook size.

That is, if the scheduled PDSCH slot/mini-slot in base station when total DAI indicating downlink DCI Number, then according to the total for including in the DCI finally received in the corresponding new feedback window of feedback slot after delay DAI determines the feedback codebook size of the feedback slot.

Determine feedback resources:

After the ACK/NACK delay that determination need to postpone when the feedback resources of corresponding feedback slot, it is divided into using quiet code This size and use dynamic codebook size both of these case:

Situation one: static codebook size is used

It is received according in the feedback window of any time slot in corresponding feedback slot after the ACK/NACK delay that need to postpone To any DCI include feedback resources instruction ARI (instruction of ACK Resource Indicator, ACK resource), determination this The Physical Uplink Control Channel PUCCH feedback resource location that ACK/NACK to be transmitted is occupied in one time slot, with anti-in the PUCCH ACK/NACK to be transmitted in any time slot is transmitted on feedback resource location.

That is, if using static codebook size, terminal thinks the corresponding new feedback window of feedback position after delay In include in all DCI ARI instructions field it is identical, feedback position is corresponding after the PUCCH resource of ARI instruction can carry delay New feedback window in all feedback information.

Situation two: dynamic codebook size is used

It, can be according to right after the ACK/NACK delay that the ARI determination indicated in DCI need to postpone when using dynamic codebook size The feedback resources for the feedback slot answered.

Wherein:
