Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.
In the embodiment of the present invention, semi-continuous scheduling transmission method can be applied to LTE (Long Term Evolution, length Phase evolution) or the mobile communication system such as 5G (5th-Generation, the 5th generation) NR (New Radio, wireless access) in.Specifically Ground, semi-continuous scheduling transmission method can be applied to the network side equipment in system, also can be applied to the UE (User in system Equipment, user equipment).
Wherein, network side equipment can be communicated with UE by network foundation.The network equipment can be evolved base station (Evolutional Node B, abbreviation eNB or eNodeB) perhaps the base station (abbreviation gNB) in 5G network or transfer point or Person's Home eNodeB etc.;UE can be mobile phone, tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital assistant, abbreviation PDA), mobile Internet access dress The terminal side equipments such as (Mobile Internet Device, MID) or wearable device (Wearable Device) are set, but It is not limited only to this.
The semi-continuous scheduling transmission method of the embodiment of the present invention is illustrated below.
Referring to Fig. 1, Fig. 1 is the flow chart of the first semi-continuous scheduling transmission method provided in an embodiment of the present invention, this The semi-continuous scheduling transmission method of embodiment can be applied to network side equipment.As shown in Figure 1, the semi-continuous scheduling of the present embodiment passes Transmission method the following steps are included:
101, semi-continuous scheduling Physical Downlink Shared Channel SPS PDSCH activation or reconfiguration confidence are sent to user equipment Breath.
In this step, SPS (Semi-Persistent Scheduling, semi-continuous scheduling) PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) it is activated or reconfigured by information and can show as dispatching PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) information of SPS PDSCH.Its In, PDCCH information can be understood as the information transmitted by PDCCH, such as DCI (Downlink Control Information, Downlink Control Information) etc..
In the present embodiment, network side equipment to UE be configured with SPS (Semi-Persistent Scheduling, it is semi-continuous Scheduling) after PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), need to pass through instruction The PDCCH of downlink SPS resource active triggers SPS PDSCH transmission.
Wherein, it can be identified by SPS C-RNTI corresponding to the PDCCH of SPS business, such as: SPS C-RNTI can With the PDCCH for identifying indicating downlink SPS resource active;It can be used for mark and update the configuration of SPS PDSCH transmission PDCCH;It can be used for the PDCCH that mark instruction scheduling SPS PDSCH is retransmitted, but be not limited only to this.
In order to distinguish the corresponding SPS type of service of PDCCH, can be carried in using the scrambled PDCCH of SPS C-RNTI NDI (New Data Indicator, new data indicator) field.
Wherein, if PDCCH carry NDI be configured to 0, i.e. NDI=0, then the PDCCH be instruction SPS resource active or The PDCCH reconfigured.It further, should if not being transmitted across SPS PDSCH active information before network side equipment PDCCH instruction activates SPS business;If being transmitted across SPS PDSCH active information before base station, PDCCH instruction The SPS business of activation is reconfigured, i.e., in the new SPS transmission opportunity determined according to the PDCCH, according to the PDCCH The relevant parameter that indicated information resets SPS PDSCH carries out SPS transmission, such as time-domain position, frequency domain resource, MCS (Modulation and Coding Scheme, modulation and coding strategy), HARQ feedback timing etc., i.e. indicated by the PDCCH Information replacement before be activated or reconfigured by instruction information in PDCCH.
If the NDI that PDCCH is carried is configured to 1, i.e. NDI=1, then the PDCCH is that instruction scheduling SPS PDSCH is retransmitted PDCCH。
Hence, it will be appreciated that, in specific practical application, SPS PDSCH that network side equipment is sent to user equipment Activation or reconfiguration information can show as scrambling using SPS C-RNTI, and the PDCCH information of NDI=0.
In LTE system, downlink transfer is this subframe scheduling, i.e. PDCCH is with corresponding PDSCH (i.e. scheduled in the PDCCH PDSCH) in the same subframe, therefore, the transmission location of first SPS PDSCH is indicating downlink SPS resource active PDCCH transmission where subframe.
In 5G NR system, downlink transfer supports across slot scheduling, i.e., the PDCCH transmitted in slot n can be with The PDSCH transmission in slot n is dispatched, the PDSCH transmission in slot n+k can also be dispatched, wherein k is greater than 0.Therefore, one Dispatching may in DCI (Downlink Control Information, Downlink Control Information) used in the PDCCH of PDSCH Comprising two instructions field, a time-domain position being used to indicate where PDSCH scheduled in the PDCCH, one is used to indicate this The HARQ feedback timing of PDSCH scheduled in PDCCH.
It should be noted that in the present embodiment, the SPS PDSCH activation or the mixing of reconfiguration information weigh automatically The HARQ feedback information for passing request HARQ feedback information and dynamic PDSCH transmissions is transmitted in different feedback positions.That is network side Equipment indicates different HARQ feedback positions for activating or reconfiguring SPS PDSCH transmission and other dynamic PDSCH transmissions.
Wherein, the feedback position of the HARQ feedback information of PDSCH transmission is anti-according to the time-domain position and HARQ of PDSCH transmission Timing (HARQ-ACK timing) is presented to determine.Specifically, HARQ feedback timing can predefine, i.e. downlink transfer Timing relationship between HARQ feedback information and the downlink transfer pre-defines, such as: for FDD (Frequency Division Duplexing, frequency division duplex) carrier wave, feeds back the HARQ feedback letter of the downlink transfer in subframe n-4 in subframe n Breath, for TDD (Time Division Duplexing, time division duplex) carrier wave, then be directed to different TDD uplink-downlink configurations, one The HARQ feedback information of downlink transfer in one downlink subframe set n-k of the corresponding feedback of a sub-frame of uplink n, wherein k ∈ K, K For for the different sub-frame of uplink downlink predetermined in different TDD uplink-downlink configuration and each TDD uplink-downlink configuration Index value;HARQ feedback timing can also be pre-configured with multiple HARQ feedback timing values by high-level signaling, then be referred to by DCI Show one of them, such as: it can be by indicating preconfigured 8 candidates of high-level signaling by 3 bit indication domains in DCI It one in HARQ feedback sequential value, can specifically determine according to actual needs, the embodiment of the present invention is not construed as limiting this.
It should be understood that in practical applications, network side equipment is logical to cannot get through scheduling and activation, or reconfigures and SPS The identical dynamic PDSCH transmissions of PDSCH transmission feedback position;Or the HARQ feedback timing of flexible modulation PDSCH transmission, with reality The hybrid automatic repeat-request HARQ feedback information and dynamic PDSCH of the existing SPS PDSCH activation or reconfiguration information pass Defeated HARQ feedback information is transmitted in different feedback positions.
Such as: if using predefined HARQ feedback timing, when network side equipment transmission SPS PDSCH activation or again When configuration information information, network side does not go to dispatch the dynamic PDSCH transmissions in the same feedback window.If using high-level signaling Multiple HARQ feedback timing values are pre-configured with, when then indicating one of them by DCI, then network side equipment can be by SPS PDSCH activation or reconfiguration information and the instruction of the HARQ feedback of dynamic PDSCH transmissions are transmitted on different time-domain positions, from And the hybrid automatic repeat-request HARQ feedback information and dynamic of SPS PDSCH activation or reconfiguration information can be made The case where HARQ feedback information of PDSCH transmission is transmitted in different feedback positions, and feedback position is avoided to be re-used.
In this way, not feeding back and appointing when SPS PDSCH activation or reconfiguration information that UE does not receive network side equipment transmission When what information, base station can be detected by DTX (Discontinuous Transmission, discontinuous transmission), that is, will test PUCCH (Physical Uplink Control Channel, the physical uplink control channel) energy arrived and a thresholding Value is compared, and that distinguish UE feedback is ACK/NACK or DTX.
Specifically, if the PUCCH energy that detects of network side equipment can determine that terminal does not exist without departing from thresholding Any information is sent on PUCCH, that is, determines that the HARQ feedback information of SPS PDSCH activation or reconfiguration information is DTX;If net The PUCCH energy that network side apparatus detects exceeds thresholding, then can determine that terminal has sent information on PUCCH, that is, determines SPS It is ACK (Acknowledgement affirmative acknowledgement (ACK)) or NACK that PDSCH, which activates the HARQ feedback information of perhaps reconfiguration information, (Negative Acknowledgement, negative response).Further, network side equipment can demodulate in PUCCH resource Information, that determine UE feedback is ACK or NACK.
As it can be seen that passing through the semi-continuous scheduling transmission method of present embodiment, for not receiving network side equipment transmission The feedback position pair of the case where SPS PDSCH activation or reconfiguration information, network side equipment and UE for SPS PDSCH transmission The feedback codebook size answered has consistent understanding, i.e. network side equipment and UE can determine the feedback in SPS PDSCH transmission Do not include the feedback information of 1 bit in the corresponding feedback code book in position, and then system data transmission performance can be improved.
Wherein, different feedback positions can show as different time slots, in the application scenarios, network side equipment for SPS PDSCH transmission and other dynamic PDSCH transmissions instruction HARQ feedback position are activated or reconfigured in different time slots; Alternatively, different feedback positions can show as that identical time slot but the nonoverlapping PUCCH resource of time-domain position can be shown as, In the application scenarios, network side equipment is indicated for activating or reconfiguring SPS PDSCH transmission and other dynamic PDSCH transmissions HARQ feedback position is in identical time slot but the nonoverlapping PUCCH resource of time-domain position.
In the present embodiment, it is contemplated that UE is receiving SPS PDSCH active information or SPS PDSCH reconfiguration information, will Different operations is executed, therefore, sends SPS PDSCH active information and SPS PDSCH weight to UE below for network side equipment The application scenarios of configuration information are illustrated respectively.
Scene one, network side equipment send SPS PDSCH active information to user equipment.
In the application scenarios, after step 101, the method also includes:
The HARQ feedback letter of the user equipment is received on the corresponding feedback position of the SPS PDSCH active information Breath;
If received HARQ feedback information is affirmative acknowledgement on the corresponding feedback position of the SPS PDSCH active information ACK or negative response NACK, it is determined that compare in the received HARQ feedback code book of feedback position of SPS PDSCH transmission comprising 1 Special SPS PDSCH feedback information;
If received HARQ feedback information is discontinuous transmission DTX on the feedback position, the SPS is retransmitted PDSCH active information, and determine and do not include 1 bit in the received HARQ feedback code book of feedback position of SPS PDSCH transmission SPS PDSCH feedback information.
In the present embodiment, due to the HARQ feedback information of SPS PDSCH active information and dynamic PDSCH transmissions HARQ feedback information is transmitted in different feedback positions, and therefore, network side equipment can be detected by DTX and distinguish UE feedback It is ACK/NACK or DTX.
In practical applications, if UE receives SPS PDSCH active information, in transmission SPS PDSCH active information Increase the SPS PDSCH feedback of 1 bit in the corresponding HARQ feedback code book (codebook) of the feedback position of HARQ feedback information Information, and to network side equipment feedback SPS PDSCH active information HARQ feedback information.Wherein, if UE is received and correctly translated Code SPS PDSCH active information is then ACK to the HARQ feedback information of network side equipment feedback SPS PDSCH active information;If UE is received but mistake decoding SPS PDSCH active information, then anti-to the HARQ of network side equipment feedback SPS PDSCH active information Feedforward information is NACK.
Network side equipment received HARQ feedback information on the corresponding feedback position of the SPS PDSCH active information is Affirmative acknowledgement ACK or negative response NACK, it is determined that in the received HARQ feedback code book of feedback position of SPS PDSCH transmission SPS PDSCH feedback information comprising 1 bit.
If UE does not receive SPS PDSCH active information, in the HARQ feedback information of transmission SPS PDSCH active information The corresponding HARQ feedback code book (codebook) of feedback position in do not increase by the SPS PDSCH feedback information of 1 bit, and to net The HARQ feedback information of network side apparatus feedback SPS PDSCH active information, it should be understood that the HARQ feedback information is shown as DTX。
Network side equipment received HARQ feedback information on the corresponding feedback position of the SPS PDSCH active information is DTX, it is determined that do not include the SPS PDSCH of 1 bit in the received HARQ feedback code book of feedback position of SPS PDSCH transmission Feedback information, and retransmit SPS PDSCH active information.It should be understood that the SPS PDSCH that network side equipment retransmits The HARQ feedback information of active information and the HARQ feedback information of dynamic PDSCH transmissions are transmitted in different feedback positions.
As it can be seen that by the above-mentioned means, network side equipment and UE can feedback position for SPS PDSCH transmission it is corresponding Feedback codebook size has consistent understanding, so as to improve system data transmission performance.
Wherein, HARQ feedback code book can be understood as carrying out the downlink transfer generation of HARQ feedback in same time domain position HARQ feedback sequence, is used to indicate whether UE has had correctly received downlink transfer, and in the present embodiment, downlink transfer can show For SPS PDSCH active information or SPS PDSCH reconfiguration information, but it is not limited only to this.
It should be noted that in embodiments of the present invention, SPS PDSCH transmission is subsequent transmission after SPS business is activated Periodic SPS PDSCH, subsequent SPS PDSCH does not have corresponding PDCCH to dispatch, but is not excluded in some cases may be used Can transmit has the SPS PDSCH of PDCCH to be used to indicate re-transmission.The feedback position of SPS PDSCH transmission is that SPS business is activated Afterwards, the feedback position of subsequent SPS PDSCH transmission.It is anti-for the corresponding HARQ of feedback position of SPS PDSCH active information The SPS PDSCH feedback information for not including 1 bit in code book is presented, but after being activated for SPS business, subsequent SPS PDSCH It include the SPS PDSCH feedback information of 1 bit in the corresponding HARQ feedback code book of the feedback position of transmission.
For convenience of understanding, it is assumed that the transmission intercal of the preconfigured SPS PDSCH of RRC signaling is 6 slot, and network side is set It is standby that a SPS PDSCH active information is had sent in the slot n of first radio frames, according to the SPS PDSCH active information And the transmission intercal of SPS PDSCH, it can determine the transmission opportunity of subsequent SPS PDSCH, i.e. transmission time-domain position is first Slot n+6 of a radio frames, slot n+2 of second radio frames, second radio frames slot n+8, and so on.Into One step, it is assumed that the SPS HARQ feedback timing of SPS PDSCH active information instruction is 4, i.e. the SPS transmitted in slot x PDSCH carries out AN feedback in slot x+4, then the SPS PDSCH active information in the slot n of first radio frames needs It is fed back in slot n+4, SPS PDSCH transmission in the slot n+6 of first radio frames is needed in second radio frames It is fed back in slot n, the SPS PDSCH transmission in the slot n+2 of second radio frames needs the slot in second radio frames It is fed back in n+6, and so on.It should be understood that above-mentioned first, second is used to characterize the timing of radio frames.
A and Fig. 2 b referring to Figure 2 together.In Fig. 2 a and Fig. 2 b, network side equipment cannot indicate other dynamics simultaneously PDSCH transmission and SPS PDSCH active information are carried out instead in the slot n+4 of first radio frames using identical PUCCH resource Feedback, in this way, since the feedback information for other dynamic PDSCH transmissions of getting along well is multiplexed the identical of the slot n+4 of first radio frames PUCCH resource, network side equipment receive UE to the feedback letter of the slot n SPS PDSCH active information transmitted in slot n+4 Breath, can distinguish the HARQ information received is ACK or NACK or DTX.
It will be appreciated that the feedback position of the subsequent SPS PDSCH transmission of network side equipment can be with other dynamics The feedback position of PDSCH transmission is identical, such as: the slot n of second radio frames in Fig. 2 a is simultaneously in first radio frames The SPS PDSCH transmission and first radio frames of slot n+6 in the dynamic PDSCH transmissions of slot n+5, first radio frames The feedback position of the dynamic PDSCH transmissions of middle slot n+8.
As shown in Figure 2 a, network side equipment is in the feedback information of the slot n+4 SPS PDSCH active information detected ACK or NACK, then network side equipment can determine the slot n of slot n+6 in first radio frames, second radio frames The corresponding HARQ feedback position the SPS PDSCH of+2 ... middle transmission, i.e., slot n of second radio frames, second radio frames The corresponding HARQ feedback code book of the middle SPS PDSCH transmission of slot n+6 ... in include 1 bit SPS PDSCH feedback letter Breath.
Assuming that using single codeword transmission mode on current carrier, then the feedback position of subsequent SPS PDSCH transmission is corresponding Feedback code this according to DAI (Downlink Assignment Index, downlink distribution index) determine codebook size add 1.
As shown in Figure 2 a, the dynamic PDSCH transmissions of slot n+5 in first radio frames, slot n in first radio frames The dynamic PDSCH transmissions of slot n+8 are simultaneously in second radio frames in+6 SPS PDSCH transmission and first radio frames Slot n in carry out HARQ feedback, and the DAI that the dynamic PDSCH transmissions of the slot n+8 of first radio frames carry is 2, then HARQ-ACK codebook size in the slot n of second radio frames is 3;Similarly, in second radio frames slot n+1 it is dynamic In state PDSCH transmission, second radio frames in the SPS PDSCH transmission, second radio frames of slot n+2 slot n+3 it is dynamic The dynamic PDSCH transmissions of slot n+4 are simultaneously in the slot of second radio frames in state PDSCH transmission and second radio frames HARQ feedback is carried out in n+6, and the DAI that the dynamic PDSCH transmissions of slot n+4 carry in second radio frames is 3, then second HARQ-ACK codebook size in a radio frames in slot n+6 is 4.
As shown in Figure 2 b, network side equipment receives UE to the slot n SPS active information transmitted in slot n+4 HARQ feedback information is DTX, and network side equipment will continue to retransmit SPS PDSCH active information, and network side equipment cannot Indicate that the SPS PDSCH activation of other dynamic PDSCH transmissions and retransmission is fed back in identical position.
In figure 2b, network side equipment retransmits SPS PDSCH activation letter in the slot n+6 of first radio frames Breath, then network side equipment cannot indicate that the SPS PDSCH active information retransmitted in dynamic PDSCH and slot n+6 uses phase Same HARQ feedback position.The dynamic PDSCH transmissions of the slot n+5 of first radio frames in Fig. 2 b, first radio frames Although the dynamic PDSCH transmissions of the SPS PDSCH active information of slot n+6 and the slot n+8 of first radio frames exist HARQ feedback is carried out on the slot n of second radio frames, but the SPS PDSCH of the slot n+6 of first radio frames activation is believed Breath and other dynamic PDSCH transmissions are fed back in the different PUCCH resources of the slot n of second radio frames.
It should be understood that if the slot n network side equipment in second radio frames does not still detect UE for weight The ACK/NACK of the SPS PDSCH active information feedback newly sent, then can be to send out again in the slot n+2 of second radio frames SPS PDSCH active information is sent, while cannot indicate to retransmit in the dynamic PDSCH and slot n+2 of second radio frames SPS PDSCH active information uses identical HARQ feedback position.The dynamic of the slot n+1 of second radio frames in Fig. 2 b The SPS PDSCH active information of the slot n+2 of PDSCH transmission, second radio frames and the slot n+3 of second radio frames Although dynamic PDSCH transmissions carry out HARQ feedback on the slot n+6 of the second radio frames, second radio frames Different PUCCHs of the SPS PDSCH active information and others dynamic PDSCH of slot n+2 in the slot n of second radio frames It is fed back in resource.
It should be noted that the slot for being used to retransmit SPS PDSCH active information in Fig. 2 b is merely illustrative, network side Equipment can retransmit SPS PDSCH in any slot after the slot n+4 of first radio frames according to the actual situation Active information, if network side equipment can retransmit SPS PDSCH active information in the slot n+5 of first radio frames, But it is not limited only to this.
Scene two, network side equipment send SPS PDSCH reconfiguration information to user equipment.
In the application scenarios, if the time-domain position of SPS PDSCH reconfiguration information instruction change SPS PDSCH transmission And/or the HARQ feedback timing of SPS PDSCH transmission, network side equipment send SPS PDSCH reconfiguration information to user equipment Afterwards, SPS PDSCH includes the first feedback position and the second feedback position, wherein the first feedback position is according to the SPS PDSCH The SPS PDSCH feedback timing of reconfiguration information instruction determines that the second feedback position is reconfigured according to the SPS PDSCH is sent SPS PDSCH feedback timing before information determines.
If the first feedback position and the second feedback position are identical, since the SPS business of UE has been activated, no matter UE whether The SPS PDSCH reconfiguration information of network side equipment transmission is received, therefore, network side equipment can be determined in SPS PDSCH It include the SPS PDSCH feedback information of 1 bit in the corresponding HARQ feedback code book of the feedback position of transmission.
If the first feedback position and the second feedback position are different, optionally, after step 101, the method also includes:
The HARQ that the user equipment feedback is received on the corresponding feedback position of the SPS PDSCH reconfiguration information is anti- Feedforward information;
If on the corresponding feedback position of the SPS PDSCH reconfiguration information received HARQ feedback information be ACK or NACK, it is determined that include the SPS of 1 bit in the received HARQ feedback code book of the first feedback position of SPS PDSCH transmission PDSCH feedback information, not comprising 1 bit in the received HARQ feedback code book of the second feedback position of SPS PDSCH transmission SPS PDSCH feedback information;
Alternatively,
If received HARQ feedback information is DTX on the corresponding feedback position of the SPS PDSCH reconfiguration information, Determine the SPS for not including 1 bit in the received HARQ feedback code book of the first feedback position of the SPS PDSCH transmission PDSCH feedback information includes 1 bit in the received HARQ feedback code book of the second feedback position of the SPS PDSCH transmission SPS PDSCH feedback information, and retransmit the SPS PDSCH reconfiguration information.
In the present embodiment, due to the HARQ feedback information of SPS PDSCH reconfiguration information and dynamic PDSCH transmissions HARQ feedback information is transmitted in different feedback positions, and therefore, network side equipment can be detected by DTX and distinguish UE feedback It is ACK/NACK or DTX.
In practical applications, if UE receives SPS PDSCH reconfiguration information, which refers to SPS PDSCH before replacement is activated or is reconfigured the information of instruction by the information shown.Therefore, UE can be the of SPS PDSCH Increase the SPS PDSCH feedback information of 1 bit in the corresponding HARQ feedback code book of one feedback position, and the first feedback position to Network side equipment feeding back ACK or NACK;Do not increase by 1 in the corresponding HARQ feedback code book of the second feedback position of SPS PDSCH The SPS PDSCH feedback information of bit, and DTX is fed back to network side equipment in the second feedback position.
Network side equipment received HARQ feedback information on the corresponding feedback position of the SPS PDSCH reconfiguration information For affirmative acknowledgement ACK or negative response NACK, it is determined that in the received HARQ feedback of the first feedback position of SPS PDSCH transmission It include the SPS PDSCH feedback information of 1 bit in code book, it is anti-in the received HARQ of the second feedback position of SPS PDSCH transmission Present the SPS PDSCH feedback information in code book comprising 1 bit.
If UE does not receive SPS PDSCH reconfiguration information, the opportunity of SPS PDSCH transmission and HARQ feedback timing are not Become, UE can increase the SPS PDSCH feedback of 1 bit in the corresponding HARQ feedback code book of the second feedback position of SPS PDSCH Information, and to network side equipment feeding back ACK or NACK;In the corresponding HARQ feedback code book of the first feedback position of SPS PDSCH In do not increase by the SPS PDSCH feedback information of 1 bit, and feed back DTX to network side equipment in the second feedback position.
Network side equipment received HARQ feedback information on the corresponding feedback position of the SPS PDSCH reconfiguration information For DTX, it is determined that do not include the SPS of 1 bit in the received HARQ feedback code book of the first feedback position of SPS PDSCH transmission PDSCH feedback information, and SPS PDSCH reconfiguration information is retransmitted, it is received in the second feedback position of SPS PDSCH transmission HARQ feedback code book in do not include the SPS PDSCH feedback information of 1 bit, and retransmit SPS PDSCH reconfiguration information. It should be understood that the HARQ feedback information and dynamic PDSCH of the SPS PDSCH reconfiguration information that network side equipment retransmits pass Defeated HARQ feedback information is transmitted in different feedback positions.
As it can be seen that by the above-mentioned means, network side equipment and UE can feedback position for SPS PDSCH transmission it is corresponding Feedback codebook size has consistent understanding, so as to improve system data transmission performance.
For convenience of understanding, it is assumed that the transmission intercal of the preconfigured SPS PDSCH of RRC signaling is 6 slot, and network side is set It is standby to have sent a SPS PDSCH reconfiguration information in the slot n of first radio frames, and in first radio frames SPS PDSCH transmission is carried out in slot n.Further, it is assumed that the SPS HARQ feedback of SPS PDSCH reconfiguration information instruction Timing is 3, and the SPS HARQ feedback timing before network side equipment sends SPS PDSCH reconfiguration information is 4.
Also referring to Fig. 3 a and Fig. 3 b.In Fig. 3 a and Fig. 3 b, network side equipment cannot indicate other dynamic PDSCH It transmits and carries out HARQ feedback in identical feedback position with the SPS PDSCH reconfiguration information sent in slot n, in this way, due to Get along well other dynamic PDSCH transmissions feedback information be multiplexed first radio frames slot n+4 identical PUCCH resource, network Side apparatus receives UE to the feedback information of the slot n SPS PDSCH reconfiguration information transmitted in slot n+3, can distinguish The HARQ information received out is ACK or NACK or DTX.
It will be appreciated that the feedback position of the subsequent SPS PDSCH transmission of network side equipment can be with other dynamics The feedback position of PDSCH transmission is identical, such as: the slot n+9 of first radio frames in Fig. 3 a is simultaneously first radio frames The feedback position of the SPS PDSCH transmission of slot n+6 in the dynamic PDSCH transmissions of middle slot n+5 and first radio frames.
Assuming that using single codeword transmission mode on current carrier, then the feedback position of subsequent SPS PDSCH transmission is corresponding Feedback code this according to DAI (Downlink Assignment Index, downlink distribution index) determine codebook size add 1.
As shown in Figure 3a, the SPS PDSCH reconfiguration information sent in slot n for network side equipment, if Slot n+3 receives the ACK or NACK that UE feeds back SPS PDSCH reconfiguration information, then it is assumed that SPS PDSCH is reconfigured Information is properly received by UE.
Network side equipment can determine not to be wrapped in the corresponding HARQ feedback code book of the second feedback position of SPS PDSCH transmission SPS PDSCH feedback information containing 1 bit, by taking the slot n+4 in first radio frames as an example, then the slot n+4 is corresponding HARQ feedback codebook size is 1.
Network side equipment can determine in the corresponding HARQ feedback code book of the first feedback position of SPS PDSCH transmission The SPS PDSCH feedback information of 1 bit, by taking the slot n+9 of first radio frames as an example, which is simultaneously first The feedback of the dynamic PDSCH transmissions of the slot n+6 of the SPS PDSCH transmission of the slot n+5 of radio frames and first radio frames Position, and the DAI that the dynamic PDSCH transmissions of the slot n+6 of first radio frames carry is 1, then the HARQ- of the slot n+9 ACK codebook size is 2.And first nothing determining for the HARQ feedback timing before sending SPS PDSCH reconfiguration information Corresponding second feedback position of the SPS PDSCH transmission of the slot n+6 of line frame, i.e., the slot n of second radio frames, network side Equipment can determine in the slot n include in corresponding HARQ feedback code book 1 bit SPS PDSCH feedback information, then should The corresponding HARQ-ACK feedback codebook size of slot n is 1.
As shown in Figure 3b, the SPS PDSCH reconfiguration information sent in slot n for base station, if in slot n+3 The information for not detecting UE feedback, i.e., receive the DTX that UE feeds back SPS PDSCH reconfiguration information in slot n+3, then Think that SPS PDSCH reconfiguration information is not properly received by UE.
Network side equipment can determine not to be wrapped in the corresponding HARQ feedback code book of the first feedback position of SPS PDSCH transmission SPS PDSCH feedback information containing 1 bit.
Network side equipment can determine in the corresponding HARQ feedback code book of the second feedback position of SPS PDSCH transmission The SPS PDSCH feedback information of 1 bit, by taking the slot n+4 of first radio frames as an example, which is simultaneously first The feedback bit of the dynamic PDSCH transmissions of the slot n+1 of the SPS PDSCH transmission of the slot n of radio frames and first radio frames It sets, and the DAI that the dynamic PDSCH transmissions of the slot n+6 of first radio frames carry is 1, then the HARQ-ACK of the slot n+4 Codebook size is 2.
Network side equipment can retransmit SPS reconfiguration information, and network in the slot n+6 of first radio frames It is identical that side apparatus cannot indicate that the SPS reconfiguration information retransmitted in dynamic PDSCH transmissions and the slot n+6 uses HARQ feedback position, in fig 3b, the dynamic PDSCH transmissions of the slot n+5 of the first radio frames and the slot n of the first radio frames + 6 SPS PDSCH reconfiguration information carries out HARQ feedback using the different PUCCH resources in the slot n+9 of the first radio frames.
Assuming that network side equipment detects what UE fed back SPS reconfiguration information in the slot n+9 of the first radio frames ACK or NACK, then network side equipment thinks the second feedback position of the SPS PDSCH transmission of the slot n+6 of the first radio frames SPS PDSCH feedback information not comprising 1 bit.By taking the slot n of second radio frames as an example, the slot of second radio frames The corresponding HARQ feedback code book of n does not include the SPS PDSCH feedback information of 1 bit, but due to the slot n of second radio frames It is simultaneously the feedback position of dynamic PDSCH transmissions in the slot n+8 of first radio frames, and dynamic PDSCH transmissions carrying DAI is 1, and therefore, the corresponding HARQ feedback code book of the slot n of second radio frames is 1.
In addition, network side equipment can determine the corresponding HARQ feedback code of the first feedback position in SPS PDSCH transmission This includes SPS PDSCH feedback information of 1 bit, by taking the slot n+5 of second radio frames as an example, second radio frames The corresponding HARQ feedback code book of slot n+5 includes the SPS PDSCH feedback information of 1 bit, in addition, second radio frames Slot n+5 is in the slot n+1 of second radio frames in dynamic PDSCH transmissions and the slot n+3 of second radio frames simultaneously The feedback position of dynamic PDSCH transmissions, and the DAI that dynamic PDSCH transmissions carry in the slot n+3 of second radio frames is 2, Then the HARQ-ACK codebook size of the slot n+4 is 3.
It should be noted that the slot for being used to retransmit SPS PDSCH reconfiguration information in Fig. 3 b is merely illustrative, network Side apparatus can retransmit SPS in any slot after the slot n+3 of first radio frames according to the actual situation PDSCH active information, as network side equipment can retransmit SPS PDSCH activation in the slot n+5 of first radio frames Information, but it is not limited only to this.
It should be understood that the application scenarios of SPS PDSCH reconfiguration information are sent to user equipment for network side equipment, If SPS PDSCH reconfiguration information does not indicate the time-domain position and/or SPS PDSCH transmission of change SPS PDSCH transmission HARQ feedback timing, frequency domain position or MCS etc. of instruction change SPS PDSCH, then network side equipment still can be according to still pressing The SPS PDSCH transmission position approved for distribution sent before SPS reconfiguration information and feedback timing are sent and received.
In the embodiment of the present invention, if network side equipment sends SPS PDSCH reconfiguration information to user equipment, and described The time-domain position of SPS PDSCH reconfiguration information instruction change SPS PDSCH transmission and/or the HARQ of SPS PDSCH transmission are anti- Timing is presented, then the corresponding HARQ feedback of the SPS PDSCH reconfiguration information is reconfigured earlier than the SPS PDSCH in time The corresponding HARQ feedback of SPS PDSCH transmission after information.
So as to avoid network side equipment and UE for the SPS PDSCH after the SPS PDSCH reconfiguration information The corresponding HARQ feedback codebook size of the feedback position of transmission generates different understanding, and then improves system data transmission Energy.
For convenience of understanding, a and Fig. 4 b referring to Figure 4 together.In Fig. 4 a and Fig. 4 b, network side equipment is sent out in slot n SPS PDSCH active information is sent, the HARQ feedback timing of instruction SPS PDSCH is 4, and SPS PDSCH is sent in slot n+5 Reconfiguration information, base station cannot indicate that confidence is reconfigured in the SPS PDSCH sent in other dynamic PDSCH transmissions and slot n+5 Breath identical position carry out HARQ feedback, and need to guarantee SPS PDSCH reconfiguration information instruction HARQ feedback when Between on earlier than the corresponding HARQ feedback of SPS PDSCH transmission after SPS PDSCH reconfiguration information.
As shown in fig. 4 a, it is assumed that single codeword transmission mode is used on current carrier, network side equipment is sent out in slot n+5 SPS PDSCH reconfiguration information is sent, the HARQ feedback time of SPS PDSCH reconfiguration information must reconfigure in SPS PDSCH SPS PDSCH transmission after information, i.e. the SPS PDSCH transmission of slot n+6 is corresponding in first radio frames in Fig. 4 a Feedback position, i.e., before the slot n of second radio frames.
Assuming that the HARQ feedback timing of SPS PDSCH reconfiguration information instruction is 4, if network side equipment is in first nothing UE is not received by the slot n+9 of line frame to the feedback of SPS PDSCH reconfiguration information, that is, detects DTX, then it can be true Determine SPS PDSCH reconfiguration information not to be properly received by UE, before network side equipment is still according to transmission SPS reconfiguration information SPS PDSCH transmission position and feedback timing sent and received.It should be understood that confidence is reconfigured for SPS PDSCH The transmission opportunity of breath, such as conveyer of the feedback information of slot n+5 to the SPS PDSCH reconfiguration information of first radio frames Meeting, as first radio frames slot n+9 between send SPS reconfiguration information before SPS PDSCH transmission chance, net Network side apparatus can independently select in the SPS PDSCH transmission chance carry out SPS PDSCH transmission, also can choose without SPS PDSCH transmission.
Such as: network side equipment, which can choose, in the slot n+6 of first radio frames does not transmit SPS PDSCH, still In the case where the SPS PDSCH reconfiguration information that UE is sent in the slot n+5 for being not received by first radio frames, still It will be considered that the slot n+6 of first radio frames is SPS PDSCH transmission chance, and anti-in the slot n of second radio frames Present ACK or NACK.Network side equipment also will be considered that the slot n in second radio frames is the slot n+ of first radio frames The 6 corresponding feedback position of SPS PDSCH transmission, according to the corresponding HARQ feedback code book of the slot n of second radio frames The codebook size that DAI is determined adds 1, i.e. the HARQ feedback codebook size in the slot n of second radio frames is 3.
As shown in Figure 4 b, it is assumed that use single codeword transmission mode on current carrier, base station is sent in slot n+5 Be SPS PDSCH reconfiguration information, it indicate HARQ-ACK feedback time must the slot n of second radio frames it Before.
Assuming that the HARQ feedback timing of SPS PDSCH reconfiguration information instruction is 4, if network side equipment is in first nothing The ACK/NACK that terminal feeds back SPS PDSCH reconfiguration information is received in the slot n+9 of line frame, then it is assumed that SPS PDSCH Reconfiguration information is properly received by UE, and network side equipment transmits position according to the SPSPDSCH that SPS PDSCH reconfiguration information indicates It sets and feeds back timing and sent and received.
Such as base station thinks that in the slot n of second radio frames be no longer the corresponding feedback position of SPS PDSCH transmission, HARQ feedback codebook size i.e. in the slot n of second radio frames is 2.Network side equipment is thought in second radio frames Slot n+1 be new SPS PDSCH transmission position, corresponding feedback position second radio frames slot n+5, then it is right The HARQ-ACK feedback code book answered is that the codebook size determined according to DAI adds 1, i.e., in the slot n+5 of next radio frames It is 4 that HARQ-ACK, which feeds back codebook size,.
In summary, the semi-continuous scheduling transmission method of the present embodiment is sent under semi-continuous scheduling physics to user equipment The shared channel SPS PDSCH activation of row or reconfiguration information;The SPS PDSCH activation or the mixing of reconfiguration information are certainly Dynamic retransmission request HARQ feedback information and the HARQ feedback information of dynamic PDSCH transmissions are transmitted in different feedback positions, can be with Guarantee that network side equipment and UE feedback codebook size corresponding for the feedback position of SPS PDSCH transmission have consistent understanding, It can guarantee guaranteeing correctly to transmit HARQ feedback information in the case where activating or reconfiguring SPS transmission, and then can be with Improve system data transmission performance.
It should be noted that the embodiment for the plurality of optional introduced in the embodiment of the present invention, can be combined with each other each other It realizes, can also be implemented separately, this embodiment of the present invention is not construed as limiting.
Referring to Fig. 5, Fig. 5 is the flow chart of second of semi-continuous scheduling transmission method provided in an embodiment of the present invention, answer For network side equipment.The main distinction of the present embodiment embodiment corresponding with Fig. 1 is:
One, in the corresponding embodiment of Fig. 1, SPS PDSCH activation or the mixing of reconfiguration information weigh automatically The HARQ feedback information for passing request HARQ feedback information and dynamic PDSCH transmissions is transmitted in different feedback positions.
But in the present embodiment, the hybrid automatic repeat-request HARQ of the SPS PDSCH activation or reconfiguration information The HARQ feedback information of feedback information and dynamic PDSCH transmissions can be transmitted in identical feedback position.
Secondly, in the corresponding embodiment of Fig. 1, UE feeding back ACK or NACK on the feedback position of SPS PDSCH transmission, UE and network side equipment think the SPS PDSCH feedback letter in the corresponding HARQ feedback code book of the feedback position comprising 1 bit Breath;UE feeds back NTX on the feedback position of SPS PDSCH transmission, and UE and network side equipment think that the feedback position is corresponding The SPS PDSCH feedback information of 1 bit is not included in HARQ feedback code book.
But in the present embodiment, UE feeding back ACK on the feedback position of SPS PDSCH transmission, UE and network side equipment are equal Think the SPS PDSCH feedback information in the corresponding HARQ feedback code book of the feedback position comprising 1 bit;UE is in SPS PDSCH NACK or NTX is fed back on the feedback position of transmission, UE and network side equipment think the corresponding HARQ feedback code of the feedback position The SPS PDSCH feedback information of 1 bit is not included in this.
As shown in figure 5, the semi-continuous scheduling transmission method of the present embodiment the following steps are included:
501, network side equipment to user equipment send semi-continuous scheduling Physical Downlink Shared Channel SPS PDSCH activation or Person's reconfiguration information.
502, the semi-continuous scheduling Physical Downlink Shared Channel SPS PDSCH that user equipment receives that network side equipment is sent swashs Living or reconfiguration information.
503, user equipment the SPS PDSCH activate or the corresponding feedback position of reconfiguration information on send mixing Automatic repeat request HARQ feedback information.
504, network side equipment the SPS PDSCH activate or the corresponding feedback position of reconfiguration information on receive institute State the hybrid automatic repeat-request HARQ feedback information of user equipment.
If 505, the user equipment HARQ feedback information is affirmative acknowledgement ACK, it is determined that in the anti-of SPS PDSCH transmission Present the SPS PDSCH feedback information in the HARQ feedback code book that position is sent comprising 1 bit;Alternatively, if the HARQ feedback is believed Breath is negative response NACK or discontinuous transmission DTX, it is determined that in the HARQ feedback that the feedback position of SPS PDSCH transmission is sent The SPS PDSCH feedback information of 1 bit is not included in code book.
If 506, the network side equipment HARQ feedback information is affirmative acknowledgement ACK, it is determined that in SPS PDSCH transmission It include the SPS PDSCH feedback information of 1 bit in the received HARQ feedback code book of feedback position;Alternatively, if the HARQ feedback Information is negative response NACK or discontinuous transmission DTX, it is determined that anti-in the received HARQ of the feedback position of SPS PDSCH transmission Present the SPS PDSCH feedback information for not including 1 bit in code book.
Wherein, the feedback position of the SPS PDSCH transmission is activated according to the SPS PDSCH or reconfiguration information refers to The SPS PDSCH feedback timing shown determines.
Specifically, in the scene that network side equipment sends SPS PDSCH active information to user equipment, described The HARQ feedback information of the user equipment is received on the corresponding feedback position of SPS PDSCH active information.If the HARQ feedback Information is ACK, then the SPS PDSCH that the feedback position of SPS PDSCH transmission can be indicated according to SPS PDSCH active information is anti- Timing is presented to determine.Certainly, if SPS PDSCH active information does not include the instructions field of SPS PDSCH feedback timing, SPS The feedback position of PDSCH transmission can be determining according to SPS PDSCH feedback timing that is predefined or being pre-configured, specifically can be according to reality Border it needs to be determined that, the embodiment of the present invention is not construed as limiting this.
In the scene that network side equipment sends SPS PDSCH reconfiguration information to user equipment, in the SPS PDSCH The HARQ feedback information of the user equipment is received on the corresponding feedback position of reconfiguration information.If the HARQ feedback information is ACK, then the SPS PDSCH feedback timing that the feedback position of SPS PDSCH transmission is indicated according to SPS PDSCH reconfiguration information are true It is fixed;If the HARQ feedback information is NACK or DTX, the feedback position of SPS PDSCH transmission is activated according to SPS PDSCH to be believed The SPS PDSCH feedback timing of breath instruction determines, alternatively, what the SPS PDSCH reconfiguration information was properly received by UE before The SPS PDSCH feedback timing of SPS PDSCH reconfiguration information instruction determines.
It should be noted that in the present embodiment, the SPS PDSCH activation or the mixing of reconfiguration information weigh automatically Passing request HARQ feedback information and the HARQ feedback information of dynamic PDSCH transmissions can be transmitted with identical different feedback positions, when So, it can also be transmitted in different feedback positions.In this way, network side equipment can accurately distinguish UE feedback be ACK, still NACK or DTX.
Therefore, in the present embodiment, if HARQ feedback information is affirmative acknowledgement ACK, network side equipment and UE can be true It is scheduled on the SPS PDSCH feedback information in the received HARQ feedback code book of feedback position of SPS PDSCH transmission comprising 1 bit; If HARQ feedback information is negative response NACK or discontinuous transmission DTX, network side equipment and UE can be determined in SPS The SPS PDSCH feedback information of 1 bit is not included in the received HARQ feedback code book of the feedback position of PDSCH transmission.
As it can be seen that by the above-mentioned means, network side equipment and UE can feedback position for SPS PDSCH transmission it is corresponding Feedback codebook size has consistent understanding, so as to improve system data transmission performance.
It should be noted that the implementation in the implementation of the present embodiment embodiment of the method corresponding with Fig. 1 is similar, The description in above method embodiment is specifically referred to, to avoid repeating, details are not described herein.
In the present embodiment, it is contemplated that UE is receiving SPS PDSCH active information or SPS PDSCH reconfiguration information, will Different operations is executed, therefore, sends SPS PDSCH active information and SPS PDSCH weight to UE below for network side equipment The application scenarios of configuration information are illustrated respectively.
Scene three, network side equipment send SPS PDSCH active information to user equipment.
For convenience of understanding, it is assumed that the transmission intercal of the preconfigured SPS PDSCH of RRC signaling is 6 slot, and network side is set It is standby that a SPS PDSCH active information is had sent in the slot n of first radio frames, the instruction of SPS PDSCH active information SPS HARQ feedback timing is 4.
A and Fig. 6 b referring to Figure 6 together.As shown in Figure 6 a, slot n+4 inspection of the network side equipment in first radio frames The feedback information of the SPS PDSCH active information measured is ACK, and UE has correctly received SPS PDSCH active information.Network side is set Standby UE thinks that the corresponding HARQ feedback code book of the feedback position of subsequent SPS PDSCH transmission includes the SPS PDSCH of 1 bit Feedback information, such as slot n+6 of first radio frames, second radio frames slot n+2 in SPS PDSCH transmission pair The HARQ feedback position answered, i.e., in the HARQ code book in the slot n of second radio frames and the slot n+6 of second radio frames It all include the SPS PDSCH feedback information of 1 bit.Assuming that use single codeword transmission mode on current carrier, then second it is wireless HARQ-ACK codebook size in the slot n of frame is 3, the HARQ-ACK codebook size in second radio frames in slot n+6 It is 4.
As shown in Figure 6 b, network side equipment receives what UE transmitted slot n in the slot n+4 of first radio frames The feedback information of SPS PDCCH active information is NACK or DTX, then UE thinks to be not properly received SPS PDCCH activation Information.Network side equipment UE thinks that the corresponding HARQ feedback code book of the feedback position of subsequent SPS PDSCH transmission includes 1 ratio Special SPS PDSCH feedback information.Assuming that using single codeword transmission mode on current carrier, then it is assumed that second radio frames HARQ-ACK codebook size in slot n is 3.
As shown in Figure 6 b, it is assumed that network side equipment has retransmitted SPS in the slot n+6 of first radio frames PDSCH active information, and network side equipment detects UE for the SPS of retransmission in the slot n of second radio frames The feeding back ACK of PDSCH active information, then it is assumed that corresponding anti-for SPS PDSCH transmission in the slot n+6 of second radio frames Position is presented, corresponding HARQ-ACK feedback code book is that the codebook size determined according to DAI adds 1, i.e., in next radio frames HARQ-ACK feedback codebook size in slot n+6 is 3.
Scene four, network side equipment send SPS PDSCH reconfiguration information to user equipment.
In the application scenarios, if the time-domain position of SPS PDSCH reconfiguration information instruction change SPS PDSCH transmission And/or the HARQ feedback timing of SPS PDSCH transmission, network side equipment send SPS PDSCH reconfiguration information to user equipment Afterwards, SPS PDSCH includes the first feedback position and the second feedback position, wherein the first feedback position is according to the SPS PDSCH The SPS PDSCH feedback timing of reconfiguration information instruction determines that the second feedback position is reconfigured according to the SPS PDSCH is sent SPS PDSCH feedback timing before information determines.
If the first feedback position and the second feedback position are identical, since the SPS business of UE has been activated, no matter UE whether The SPS PDSCH reconfiguration information of network side equipment transmission is received, therefore, network side equipment can be determined in SPS PDSCH It include the SPS PDSCH feedback information of 1 bit in the corresponding HARQ feedback code book of the feedback position of transmission.
If the first feedback position and the second feedback position are different, optionally, step 506 can specifically be showed themselves in that
If the HARQ feedback information is ACK, it is determined that in the received HARQ of third feedback position of SPS PDSCH transmission The SPS PDSCH feedback information in code book comprising 1 bit is fed back, it is received in the 4th feedback position of SPS PDSCH transmission The SPS PDSCH feedback information of 1 bit is not included in HARQ feedback code book;
Alternatively,
If the HARQ feedback information is NACK or DTX, it is determined that in the third feedback position of SPS PDSCH transmission The SPS PDSCH feedback information for not including 1 bit in received HARQ feedback code book, the described 4th of SPS PDSCH transmission the In the received HARQ feedback code book of feedback position include the SPS PDSCH feedback information of 1 bit, and retransmits the SPS PDSCH reconfiguration information;
Wherein, when the third feedback position is fed back according to the SPS PDSCH that the SPS PDSCH reconfiguration information indicates Sequence determines that the 4th feedback position feeds back timing according to the SPS PDSCH before sending the SPS PDSCH reconfiguration information It determines.
Step 505 can specifically show themselves in that
If the HARQ feedback information is ACK, it is determined that in the HARQ that the third feedback position of SPS PDSCH transmission is sent The SPS PDSCH feedback information in code book comprising 1 bit is fed back, is sent in the 4th feedback position of SPS PDSCH transmission The SPS PDSCH feedback information of 1 bit is not included in HARQ feedback code book;
Alternatively,
If the HARQ feedback information is NACK or DTX, sent in the third feedback position of SPS PDSCH transmission HARQ feedback code book in do not include 1 bit SPS PDSCH feedback information, SPS PDSCH transmission it is described 4th feedback It include the SPS PDSCH feedback information of 1 bit in the HARQ feedback code book that position is sent;
Wherein, the third feedback position is anti-according to the SPS PDSCH for receiving the SPS PDSCH reconfiguration information instruction It presents timing to determine, the 4th feedback position is fed back according to the SPS PDSCH before receiving the SPS PDSCH reconfiguration information Timing determines.
As it can be seen that by the above-mentioned means, network side equipment and UE can feedback position for SPS PDSCH transmission it is corresponding Feedback codebook size has consistent understanding, so as to improve system data transmission performance.
It should be noted that the implementation in the implementation of the present embodiment embodiment of the method corresponding with Fig. 1 is similar, The description in above method embodiment is specifically referred to, to avoid repeating, details are not described herein.
For convenience of understanding, it is assumed that the transmission intercal of the preconfigured SPS PDSCH of RRC signaling is 6 slot, and network side is set It is standby to have sent a SPS PDSCH reconfiguration information in the slot n of first radio frames, and in first radio frames SPS PDSCH transmission is carried out in slot n.Further, it is assumed that the SPS HARQ feedback of SPS PDSCH reconfiguration information instruction Timing is 3, and the SPS HARQ feedback timing before network side equipment sends SPS PDSCH reconfiguration information is 4.

If network side equipment detects UE for SPS PDSCH reconfiguration information in the slot n+3 of first radio frames The information of feedback is NACK or DTX, then it is assumed that SPS PDSCH reconfiguration information is not properly received by UE.
Network side equipment and UE can be determined in the corresponding HARQ feedback code book of the third feedback position of SPS PDSCH transmission SPS PDSCH feedback information not comprising 1 bit.
Network side equipment and UE can be determined in the corresponding HARQ feedback code book of the 4th feedback position of SPS PDSCH transmission SPS PDSCH feedback information comprising 1 bit, by taking the slot n+4 of first radio frames as an example, then the slot n+4 is corresponding It is 2 that HARQ-ACK, which feeds back codebook size,.
Network side equipment can retransmit SPS PDSCH reconfiguration information in the slot n+6 of first radio frames, The feedback position of SPS PDSCH reconfiguration information, i.e., the slot n+9 of first radio frames do not include the SPS PDSCH of 1 bit Feedback information, then its corresponding HARQ-ACK feedback codebook size is 2.
Assuming that network side equipment, which detects UE in the slot n+9 of first radio frames, is reconfigured confidence for SPS PDSCH The ACK of feedback is ceased, then network side equipment and UE think the 4th feedback of the SPS PDSCH transmission of the slot n+6 of the first radio frames Position, i.e., the slot n of second radio frames is corresponding to feed back the SPS PDSCH feedback information for not including 1 bit in code book, then The corresponding HARQ-ACK feedback codebook size of the slot n is 1.
In addition, network side equipment and UE can determine that the third feedback position in subsequent SPS PDSCH transmission is corresponding HARQ feedback code book includes the SPS PDSCH feedback information of 1 bit.By taking the slot n+5 of second radio frames as an example, second The corresponding HARQ feedback code book of the slot n+5 of radio frames includes the SPS PDSCH feedback information of 1 bit, then its is corresponding HARQ-ACK feedback code book is that the codebook size determined according to DAI adds 1, i.e., the HARQ- in the slot n+5 of second radio frames It is 3 that ACK, which feeds back codebook size,.
In the embodiment of the present invention, if network side equipment sends SPS PDSCH reconfiguration information to user equipment, and described The time-domain position of SPS PDSCH reconfiguration information instruction change SPS PDSCH transmission and/or the HARQ of SPS PDSCH transmission are anti- Timing is presented, then the corresponding HARQ feedback of the SPS PDSCH reconfiguration information is reconfigured earlier than the SPS PDSCH in time The corresponding HARQ feedback of SPS PDSCH transmission after information.
