Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a semi-persistent scheduling transmission method, a network side device, and a user terminal.

Background technique

Supports SPS (Semi-Persistent Scheduling) in mobile communication systems, such as LTE (Long Term Evolution) or 5G (5th-Generation, 4th Generation) NR (New Radio) systems. The PDSCH (Physical Downlink Shared Channel) transmission and the dynamic (dynamic) PDSCH transmission, wherein the dynamic PDSCH transmission may be represented as a PDSCH transmission having a corresponding PDCCH (Physical Downlink Control Channel).

In the current mobile communication system, when the UE (User Equipment, User Equipment) does not receive the SPS PDSCH activation or reconfiguration information, it will not be sent at the feedback position of the SPS PDSCH transmission when the SPS PDSCH is activated or reconfigured. The feedback codebook adds 1-bit feedback information, but the network side device cannot determine from the feedback information of the terminal whether the UE does not receive the SPS PDSCH activation or reconfiguration information or the erroneous demodulation of the SPS PDSCH activation or reconfiguration information. The network side device considers that the 1-bit feedback information is not included in the feedback codebook sent by the feedback position of the SPS PDSCH transmission. The UE and the network side device have different understandings of the codebook size of the SPS PDSCH transmission, thereby causing the system data transmission performance to be degraded.

Therefore, it is necessary to propose a semi-persistent scheduling transmission method, so that the UE and the network side device have the same understanding of the codebook size of the SPS PDSCH transmission.

Detailed ways

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

In the embodiment of the present disclosure, the semi-persistent scheduling transmission method may be applied to a mobile communication system such as LTE (Long Term Evolution) or 5G (5th-Generation, fifth generation) NR (New Radio). Specifically, the semi-persistent scheduling transmission method may be applied to a network side device in the system, or may be applied to a UE (User Equipment) in the system.

The network side device can establish communication with the UE through the network. The network device may be an evolved base station (eNB or eNodeB), or a base station (referred to as gNB) in a 5G network, or a transmission point or a home base station; the UE may be a mobile phone or a tablet (Tablet Personal Computer). A terminal device such as a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device (Wearable Device), but is not limited thereto.

The semi-persistent scheduling transmission method of the embodiment of the present disclosure will be described below.

Please refer to FIG. 1. FIG. 1 is a flowchart of a first semi-persistent scheduling transmission method according to an embodiment of the present disclosure. The semi-persistent scheduling transmission method in this embodiment may be applied to a network side device. As shown in FIG. 1, the semi-persistent scheduling transmission method of this embodiment includes the following steps:

101. Send a semi-persistent scheduling physical downlink shared channel SPS PDSCH activation or reconfiguration information to the user equipment.

In this step, the SPS (Physical Downlink Shared Channel) activation or reconfiguration information may be expressed as a PDCCH (Physical Downlink Control Channel) for scheduling the SPS PDSCH. Control channel) information. The PDCCH information can be understood as information transmitted through the PDCCH, such as DCI (Downlink Control Information).

In this embodiment, after the network side device configures the SPS (Physical Downlink Shared Channel) on the UE, the SPS PDSCH needs to be triggered by the PDCCH indicating the activation of the downlink SPS resource. transmission.

The PDCCH corresponding to the SPS service may be identified by the SPS C-RNTI, for example, the SPS C-RNTI may be used to identify the PDCCH indicating the activation of the downlink SPS resource, and may also be used to identify the PDCCH that updates the SPS PDSCH transmission configuration. It is used to identify a PDCCH indicating scheduling SPS PDSCH retransmission, but is not limited thereto.

In order to distinguish the SPS service type corresponding to the PDCCH, an NDI (New Data Indicator) field may be carried in the PDCCH scrambled using the SPS C-RNTI.

If the NDI configured by the PDCCH is 0, that is, NDI=0, the PDCCH is a PDCCH indicating SPS resource activation or reconfiguration. Further, if the network side device has not previously sent the SPS PDSCH activation information, the PDCCH indicates that the SPS service is activated; if the base station has previously sent the SPS PDSCH activation information, the PDCCH indicates that the activated SPS service is reconfigured, that is, In the new SPS transmission opportunity determined according to the PDCCH, SPS transmission is re-set according to the information indicated by the PDCCH, such as time domain location, frequency domain resource, MCS (Modulation and Coding Scheme), modulation and coding. Policy), HARQ feedback timing, etc., that is, the information indicated by the PDCCH is replaced with the indication information in the PDCCH before activation or reconfiguration.

If the NDI carried by the PDCCH is configured to be 1, that is, NDI=1, the PDCCH is a PDCCH indicating that the SPS PDSCH retransmission is scheduled.

Therefore, it can be understood that, in a specific practical application, the SPS PDSCH activation or reconfiguration information sent by the network side device to the user equipment may be expressed as PDCCH information that is scrambled by the SPS C-RNTI and has NDI=0.

In the LTE system, the downlink transmission is the subframe scheduling, that is, the PDCCH is in the same subframe as the corresponding PDSCH (that is, the PDSCH scheduled by the PDCCH), and therefore, the transmission position of the first SPS PDSCH is the indication of the downlink SPS resource activation. The subframe in which the PDCCH transmission is located.

In the 5G NR system, downlink transmission supports inter-slot scheduling, that is, one PDCCH transmitted in slot n can schedule PDSCH transmission in slot n, and can also schedule PDSCH transmission in slot n+k, where k is greater than zero. Therefore, the DCI (Downlink Control Information) used by the PDCCH for scheduling the PDSCH may include two indication fields, one for indicating the time domain location of the PDSCH scheduled by the PDCCH, and one for indicating the PDCCH. The HARQ feedback timing of the scheduled PDSCH.

It should be noted that, in this embodiment, the hybrid automatic repeat request HARQ feedback information of the SPS PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions. That is, the network side device indicates different HARQ feedback positions for activating or reconfiguring the SPS PDSCH transmission and other dynamic PDSCH transmissions.

The feedback position of the HARQ feedback information of the PDSCH transmission is determined according to the time domain location of the PDSCH transmission and the HARQ-ACK timing. Specifically, the HARQ feedback timing may be predefined, that is, the timing relationship between the downlink transmission HARQ feedback information and the downlink transmission is predefined, for example, for FDD (Frequency Division Duplexing) carrier, In the subframe n, the HARQ feedback information of the downlink transmission in the subframe n-4 is fed back. For the TDD (Time Division Duplexing) carrier, the uplink and downlink configurations are different for one TDD, and one downlink subframe n corresponds to a downlink. The downlink transmission HARQ feedback information in the subframe set nk, where k ∈ K, K is a predefined downlink index value for different TDD uplink and downlink configurations and different uplink subframes in each TDD uplink and downlink configuration; HARQ feedback The timing may also pre-configure a plurality of HARQ feedback timing values through the high layer signaling, and then indicate one of them through the DCI. For example, the eight candidate HARQ feedback sequence values pre-configured by the high-level signaling may be indicated by the 3-bit indication field in the DCI. The one of the embodiments of the present disclosure is not limited thereto.

It should be understood that, in practical applications, the network side device does not schedule and activate, or reconfigures the dynamic PDSCH transmission with the same SPS PDSCH transmission feedback position; or flexibly adjusts the HARQ feedback timing of the PDSCH transmission to implement the SPS. The hybrid automatic repeat request HARQ feedback information of the PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions.

For example, if the predefined HARQ feedback timing is used, when the network side device sends the SPS PDSCH activation or reconfiguration information, the network side does not schedule the dynamic PDSCH transmission in the same feedback window. If a plurality of HARQ feedback timing values are pre-configured using the high layer signaling, and then one of the DCI indications is indicated by the DCI, the network side device may indicate the SPS PDSCH activation or reconfiguration information and the HARQ feedback of the dynamic PDSCH transmission at different time domain locations. The transmission may be such that the hybrid automatic retransmission request HARQ feedback information of the SPS PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions, thereby avoiding occurrence of the feedback position being multiplexed.

In this way, when the UE does not receive the SPS PDSCH activation or reconfiguration information sent by the network side device and does not feed back any information, the base station can detect through the DTX (Discontinuous Transmission), that is, the detected PUCCH (Physical Uplink Control Channel). The physical uplink control channel) energy is compared with a threshold value to distinguish whether the UE feeds back ACK/NACK or DTX.

Specifically, if the detected PUCCH energy of the network side device does not exceed the threshold, it may be determined that the terminal does not send any information on the PUCCH, that is, the HARQ feedback information that determines the SPS PDSCH activation or reconfiguration information is DTX; if the network side device detects If the PUCCH energy exceeds the threshold, it may be determined that the terminal sends information on the PUCCH, that is, the HARQ feedback information that determines the SPS PDSCH activation or reconfiguration information is ACK (Acknowledgement) or NACK (Negative Acknowledgement). Further, the network side device may demodulate information on the PUCCH resource to determine whether the UE feeds back an ACK or a NACK.

It can be seen that, by using the semi-persistent scheduling transmission method of the present embodiment, for the case where the SPS PDSCH activation or reconfiguration information sent by the network side device is not received, the feedback codebook size corresponding to the feedback position of the SPS PDSCH transmission by the network side device and the UE is There is a consistent understanding that both the network side device and the UE can determine that the feedback codebook corresponding to the feedback position of the SPS PDSCH transmission does not include 1-bit feedback information, thereby improving system data transmission performance.

The different feedback positions may be represented by different time slots. In this application scenario, the network side device indicates that the HARQ feedback position is in different time slots for activating or reconfiguring the SPS PDSCH transmission and other dynamic PDSCH transmissions; or different The feedback location may be represented as a PUCCH resource that may behave as the same time slot but the time domain location does not overlap. In this application scenario, the network side device indicates that the HARQ feedback position is in response to activating or reconfiguring the SPS PDSCH transmission and other dynamic PDSCH transmissions. At the same time, the gaps but the time domain locations do not overlap in the PUCCH resources.

In this embodiment, it is considered that the UE performs different operations when receiving the SPS PDSCH activation information or the SPS PDSCH reconfiguration information. Therefore, the following applies to the network side device to send the SPS PDSCH activation information and the SPS PDSCH reconfiguration information to the UE. The scenes are explained separately.

Scenario 1: The network side device sends SPS PDSCH activation information to the user equipment.

In the application scenario, after step 101, the method further includes:

In this embodiment, since the HARQ feedback information of the SPS PDSCH activation information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions, the network side device can distinguish whether the UE feeds back ACK/NACK or DTX through DTX detection. .

In an actual application, if the UE receives the SPS PDSCH activation information, the UE adds a 1-bit SPS PDSCH feedback information to the HARQ feedback codebook corresponding to the feedback position of the HARQ feedback information of the SPS PDSCH activation information, and adds the information to the network. The side device feeds back the HARQ feedback information of the SPS PDSCH activation information. If the UE receives and correctly decodes the SPS PDSCH activation information, the HARQ feedback information of the SPS PDSCH activation information is fed back to the network side device as an ACK; if the UE receives but incorrectly decodes the SPS PDSCH activation information, the SPS is fed back to the network side device. The HARQ feedback information of the PDSCH activation information is NACK.

If the HARQ feedback information received by the network side device at the feedback position corresponding to the SPS PDSCH activation information is a positive acknowledgement ACK or a negative acknowledgement NACK, it is determined that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission includes a 1-bit SPS. PDSCH feedback information.

If the UE does not receive the SPS PDSCH activation information, the SPS PDSCH feedback information is not added to the HARQ feedback codebook (codebook) corresponding to the feedback location of the HARQ feedback information of the SPS PDSCH activation information, and the feedback is sent to the network side device. The HARQ feedback information of the SPS PDSCH activation information should be understood that the HARQ feedback information behaves as DTX.

If the HARQ feedback information received by the network side device at the feedback position corresponding to the SPS PDSCH activation information is DTX, it is determined that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission does not include the 1-bit SPS PDSCH feedback information, and Resend the SPS PDSCH activation information. It should be understood that the HARQ feedback information of the SPS PDSCH activation information retransmitted by the network side device and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions.

It can be seen that, in the foregoing manner, the network side device and the UE can have a consistent understanding of the feedback codebook size corresponding to the feedback position of the SPS PDSCH transmission, thereby improving system data transmission performance.

The HARQ feedback codebook can be used as the HARQ feedback sequence generated by the downlink transmission of the HARQ feedback in the same time domain position, and is used to indicate whether the UE correctly receives the downlink transmission. In this embodiment, the downlink transmission may be expressed as SPS PDSCH. Activation information or SPS PDSCH reconfiguration information, but is not limited to this.

It should be noted that, in the embodiment of the present disclosure, after the SPS PDSCH transmission is activated, the SPS PDSCH is subsequently transmitted, and the subsequent SPS PDSCH does not have a corresponding PDCCH scheduling, but it is not excluded that the transmission may be performed in some cases. The SPS PDSCH of the PDCCH is used to indicate retransmission. The feedback position of the SPS PDSCH transmission is the feedback position of the subsequent SPS PDSCH transmission after the SPS service is activated. The one-bit SPS PDSCH feedback information is not included in the HARQ feedback codebook corresponding to the feedback location of the SPS PDSCH activation information, but after the SPS service is activated, the HARQ feedback codebook corresponding to the feedback position of the subsequent SPS PDSCH transmission includes 1 Bit SPS PDSCH feedback information.

For ease of understanding, it is assumed that the transmission interval of the SPS PDSCH pre-configured by the RRC signaling is 6 slots, and the network side device transmits an SPS PDSCH activation information in the slot n of the first radio frame, according to the SPS PDSCH activation information and the SPS. The transmission interval of the PDSCH can determine the transmission opportunity of the subsequent SPS PDSCH, that is, the transmission time domain position is the slot n+6 of the first radio frame, the slot n+2 of the second radio frame, and the slot n of the second radio frame. +8, and so on. Further, assuming that the SPS HARQ feedback timing indicated by the SPS PDSCH activation information is 4, that is, the SPS PDSCH transmitted in the slot x performs AN feedback in slot x+4, the SPS PDSCH activation information in the slot n of the first radio frame is required. In slot n+4, the SPS PDSCH transmission in slot n+6 of the first radio frame needs to be fed back in the slot n of the second radio frame, and the SPS PDSCH in slot n+2 of the second radio frame. The transmission needs to be fed back in slot n+6 of the second radio frame, and so on. It should be understood that the first and second above are used to characterize the timing of the radio frame.

Please refer to Figure 2a and Figure 2b together. In FIG. 2a and FIG. 2b, the network side device cannot simultaneously indicate that other dynamic PDSCH transmissions and SPS PDSCH activation information are fed back in the slot n+4 of the first radio frame using the same PUCCH resource, so that The feedback information of the PDSCH transmission multiplexes the same PUCCH resource of the slot n+4 of the first radio frame, and the network side device receives the feedback information of the SPS PDSCH activation information transmitted by the UE to the slot n in the slot n+4, and can distinguish the reception. The HARQ information to be sent is ACK or NACK, or DTX.

However, it should be understood that the feedback position of the subsequent SPS PDSCH transmission of the network side device may be the same as the feedback position of other dynamic PDSCH transmissions, for example, the slot n of the second radio frame in FIG. 2a is the first radio frame at the same time. The dynamic PDSCH transmission of the slot n+5, the SPS PDSCH transmission of the slot n+6 in the first radio frame, and the feedback position of the dynamic PDSCH transmission of the slot n+8 in the first radio frame.

As shown in FIG. 2a, the feedback information of the SPS PDSCH activation information detected by the network side device in the slot n+4 is ACK or NACK, and the network side device can determine the slot n+6 and the second in the first radio frame. The HARQ feedback position corresponding to the SPS PDSCH transmitted in the slot n+2 of the radio frame, that is, the HARQ feedback corresponding to the SPS PDSCH transmission in the slot n of the second radio frame, the slot n+6 of the second radio frame... The codebook contains 1 bit of SPS PDSCH feedback information.

Assuming that the single codeword transmission mode is used on the current carrier, the feedback codebook corresponding to the feedback position of the subsequent SPS PDSCH transmission is incremented by one according to the codebook size determined by the DAI (Downlink Assignment Index).

As shown in Figure 2a, the dynamic PDSCH transmission of slot n+5 in the first radio frame, the SPS PDSCH transmission of slot n+6 in the first radio frame, and the dynamic PDSCH transmission of slot n+8 in the first radio frame At the same time, the HARQ feedback is performed in the slot n of the second radio frame, and the dynamic PDSCH transmission of the slot n+8 of the first radio frame carries the DAI of 2, and the HARQ-ACK in the slot n of the second radio frame The codebook size is 3; similarly, the dynamic PDSCH transmission of slot n+1 in the second radio frame, the SPS PDSCH transmission of slot n+2 in the second radio frame, and the slot n+3 in the second radio frame Dynamic PDSCH transmission and dynamic PDSCH transmission of slot n+4 in the second radio frame simultaneously perform HARQ feedback in slot n+6 of the second radio frame, and dynamic PDSCH transmission of slot n+4 in the second radio frame The carried DAI is 3, and the HARQ-ACK codebook size in slot n+6 in the second radio frame is 4.

As shown in FIG. 2b, the HARQ feedback information that the network side device receives the SPS activation information transmitted by the UE to the slot n in the slot n+4 is DTX, and the network side device continues to resend the SPS PDSCH activation information, and the network side device cannot indicate Other dynamic PDSCH transmissions and retransmitted SPS PDSCH activations are fed back at the same location.

In FIG. 2b, the network side device resends the SPS PDSCH activation information in the slot n+6 of the first radio frame, and the network side device cannot indicate that the dynamic PDSCH and the retransmitted SPS PDSCH activation information in the slot n+6 are the same. The location of the HARQ feedback. The dynamic PDSCH transmission of slot n+5 of the first radio frame in FIG. 2b, the SPS PDSCH activation information of slot n+6 of the first radio frame, and the dynamic PDSCH transmission of slot n+8 of the first radio frame are both Performing HARQ feedback on slot n of the second radio frame, but SPS PDSCH activation information of slot n+6 of the first radio frame and other dynamic PDSCH transmissions are fed back on different PUCCH resources of slot n of the second radio frame .

It can be understood that if the slot n network side device of the second radio frame still does not detect the ACK/NACK of the UE for the retransmitted SPS PDSCH activation information feedback, the second radio frame may be in the slot n+2 again. The SPS PDSCH activation information is transmitted while not indicating that the dynamic PDSCH and the retransmitted SPS PDSCH activation information in the slot n+2 of the second radio frame use the same HARQ feedback position. The dynamic PDSCH transmission of slot n+1 of the second radio frame in FIG. 2b, the SPS PDSCH activation information of slot n+2 of the second radio frame, and the dynamic PDSCH transmission of slot n+3 of the second radio frame are both Performing HARQ feedback on slot n+6 of the second radio frame, but SPS PDSCH activation information of slot n+2 of the second radio frame and other dynamic PDSCH are on different PUCCH resources of slot n of the second radio frame Give feedback.

It should be noted that the slot for resending the SPS PDSCH activation information in FIG. 2b is only an example, and the network side device may resend the SPS PDSCH in any slot after the slot n+4 of the first radio frame according to actual conditions. The activation information, such as the network side device, may resend the SPS PDSCH activation information in slot n+5 of the first radio frame, but is not limited thereto.

Scenario 2: The network side device sends SPS PDSCH reconfiguration information to the user equipment.

In this application scenario, if the SPS PDSCH reconfiguration information indicates that the time domain location of the SPS PDSCH transmission and/or the HARQ feedback timing of the SPS PDSCH transmission is changed, and the network side device sends the SPS PDSCH reconfiguration information to the user equipment, the SPS PDSCH includes the first a feedback position and a second feedback position, wherein the first feedback position is determined according to an SPS PDSCH feedback timing indicated by the SPS PDSCH reconfiguration information, and the second feedback position is in accordance with an SPS PDSCH feedback timing before the SPS PDSCH reconfiguration information is sent. determine.

If the first feedback location and the second feedback location are the same, since the SPS service of the UE has been activated, whether the UE receives the SPS PDSCH reconfiguration information sent by the network side device, the network side device may determine the SPS PDSCH transmission. The HARQ feedback codebook corresponding to the feedback location includes 1-bit SPS PDSCH feedback information.

If the first feedback location and the second feedback location are different, optionally, after step 101, the method further includes:

or,

If the HARQ feedback information received at the feedback position corresponding to the SPS PDSCH reconfiguration information is DTX, determining that the HARQ feedback codebook received at the first feedback position of the SPS PDSCH transmission does not include the 1-bit SPS PDSCH feedback And transmitting, in the HARQ feedback codebook received by the second feedback position of the SPS PDSCH transmission, 1-bit SPS PDSCH feedback information, and resending the SPS PDSCH reconfiguration information.

In this embodiment, the HARQ feedback information of the SPS PDSCH reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions. Therefore, the network side device can distinguish whether the UE feeds back ACK/NACK or the DTX detection. DTX.

In an actual application, if the UE receives the SPS PDSCH reconfiguration information, the information indicated by the SPS PDSCH reconfiguration information will replace the information of the previous SPS PDSCH activation or reconfiguration indication. Therefore, the UE adds 1 bit of SPS PDSCH feedback information to the HARQ feedback codebook corresponding to the first feedback position of the SPS PDSCH, and feeds back ACK or NACK to the network side device at the first feedback position; the second feedback of the SPS PDSCH The 1-bit SPS PDSCH feedback information is not added to the HARQ feedback codebook corresponding to the location, and the DTX is fed back to the network side device at the second feedback location.

The HARQ feedback information received by the network side device at the feedback position corresponding to the SPS PDSCH reconfiguration information is a positive acknowledgment ACK or a negative acknowledgment NACK, and the HARQ feedback codebook received at the first feedback position of the SPS PDSCH transmission is determined to include 1 The SPS PDSCH feedback information of the bit includes 1-bit SPS PDSCH feedback information in the HARQ feedback codebook received at the second feedback position of the SPS PDSCH transmission.

If the UE does not receive the SPS PDSCH reconfiguration information, the timing of the SPS PDSCH transmission and the HARQ feedback timing are unchanged, and the UE adds 1 bit of SPS PDSCH feedback information to the HARQ feedback codebook corresponding to the second feedback position of the SPS PDSCH. The ACK or the NACK is fed back to the network side device; the SPS PDSCH feedback information of the 1-bit is not added to the HARQ feedback codebook corresponding to the first feedback position of the SPS PDSCH, and the DTX is fed back to the network side device at the second feedback position.

The HARQ feedback information received by the network side device at the feedback position corresponding to the SPS PDSCH reconfiguration information is DTX, and then determining that the HARQ feedback codebook received at the first feedback position of the SPS PDSCH transmission does not include the 1-bit SPS PDSCH feedback. Information, and resending the SPS PDSCH reconfiguration information, does not include 1-bit SPS PDSCH feedback information in the HARQ feedback codebook received at the second feedback position of the SPS PDSCH transmission, and retransmits the SPS PDSCH reconfiguration information. It should be understood that the HARQ feedback information of the SPS PDSCH reconfiguration information retransmitted by the network side device and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions.

For ease of understanding, it is assumed that the transmission interval of the SPS PDSCH pre-configured by the RRC signaling is 6 slots, and the network side device transmits one SPS PDSCH reconfiguration information in the slot n of the first radio frame, and is in the first radio frame. SPS PDSCH transmission is performed in slot n. Further, it is assumed that the SPS HARQ feedback timing indicated by the SPS PDSCH reconfiguration information is 3, and the SPS HARQ feedback timing before the network side device transmits the SPS PDSCH reconfiguration information is 4.

Please refer to Figure 3a and Figure 3b together. In FIG. 3a and FIG. 3b, the network side device cannot indicate that other dynamic PDSCH transmissions and SPS PDSCH reconfiguration information sent in the slot n perform HARQ feedback at the same feedback position, such that feedback information is not transmitted due to other dynamic PDSCHs. The same PUCCH resource of the slot n+4 of the first radio frame is multiplexed, and the network side device receives the feedback information of the SPS PDSCH reconfiguration information transmitted by the UE to the slot n in the slot n+3, and can distinguish the received HARQ information. Is ACK or NACK, or DTX.

However, it should be understood that the feedback position of the subsequent SPS PDSCH transmission of the network side device may be the same as the feedback position of other dynamic PDSCH transmissions. For example, the slot n+9 of the first radio frame in FIG. 3a is the first one. The dynamic PDSCH transmission of slot n+5 in the radio frame and the feedback position of the SPS PDSCH transmission of slot n+6 in the first radio frame.

As shown in FIG. 3a, for the SPS PDSCH reconfiguration information sent by the network side device in the slot n, if the ACK or NACK fed back by the UE to the SPS PDSCH reconfiguration information is received in the slot n+3, the SPS PDSCH reconfiguration information is considered. Has been correctly received by the UE.

The network side device may determine that the SPS PDSCH feedback information does not include one bit in the HARQ feedback codebook corresponding to the second feedback position of the SPS PDSCH transmission, and the slot n+4 in the first radio frame is taken as an example, then the slot n+ 4 The corresponding HARQ feedback codebook size is 1.

The network side device may determine that the HARQ feedback code corresponding to the first feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, and the slot n+9 of the first radio frame is taken as an example, and the slot n+9 is simultaneously The feedback position of the SPS PDSCH transmission of the slot n+5 of the first radio frame and the dynamic PDSCH transmission of the slot n+6 of the first radio frame, and the dynamic PDSCH transmission carried by the slot n+6 of the first radio frame When the DAI is 1, the HARQ-ACK codebook size of the slot n+9 is 2. And the second feedback position corresponding to the SPS PDSCH transmission of the slot n+6 of the first radio frame determined by the HARQ feedback timing before the SPS PDSCH reconfiguration information is sent, that is, the slot n of the second radio frame, the network side device may And determining that the corresponding HARQ feedback codebook in the slot n includes 1-bit SPS PDSCH feedback information, and the size of the HARQ-ACK feedback codebook corresponding to the slot n is 1.

As shown in FIG. 3b, for the SPS PDSCH reconfiguration information sent by the base station in the slot n, if the UE feedback information is not detected in the slot n+3, the UE receives the SPS PDSCH reconfiguration information feedback in the slot n+3. The DTX is considered to be that the SPS PDSCH reconfiguration information is not correctly received by the UE.

The network side device may determine that the SPS PDSCH feedback information does not include 1 bit in the HARQ feedback codebook corresponding to the first feedback position of the SPS PDSCH transmission.

The network side device may determine that the HARQ feedback code corresponding to the second feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, and the slot n+4 of the first radio frame is taken as an example, and the slot n+4 is simultaneously The feedback position of the SPS PDSCH transmission of the slot n of the first radio frame and the dynamic PDSCH transmission of the slot n+1 of the first radio frame, and the DAI carried by the dynamic PDSCH transmission of the slot n+6 of the first radio frame is 1, the size of the HARQ-ACK codebook of the slot n+4 is 2.

The network side device may resend the SPS reconfiguration information in the slot n+6 of the first radio frame, and the network side device cannot indicate that the dynamic PDSCH transmission and the retransmitted SPS reconfiguration information in the slot n+6 use the same HARQ. Feedback position, in FIG. 3b, the dynamic PDSCH transmission of slot n+5 of the first radio frame and the SPS PDSCH reconfiguration information of slot n+6 of the first radio frame use different slots n+9 of the first radio frame The PUCCH resource performs HARQ feedback.

It is assumed that the network side device detects the ACK or NACK fed back by the UE for the SPS reconfiguration information in the slot n+9 of the first radio frame, and the network side device considers the second feedback of the SPS PDSCH transmission of the slot n+6 of the first radio frame. The location does not contain 1 bit of SPS PDSCH feedback information. Taking the slot n of the second radio frame as an example, the HARQ feedback code corresponding to the slot n of the second radio frame does not include the 1-bit SPS PDSCH feedback information, but since the slot n of the second radio frame is the first The feedback position of the dynamic PDSCH transmission in the slot n+8 of the radio frame, and the DAI carried in the dynamic PDSCH transmission is 1, therefore, the HARQ feedback codebook corresponding to the slot n of the second radio frame is 1.

In addition, the network side device may determine that the HARQ feedback codebook corresponding to the first feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, and takes the slot n+5 of the second radio frame as an example, the second radio frame. The HARQ feedback codebook corresponding to the slot n+5 includes 1-bit SPS PDSCH feedback information, and in addition, the slot n+5 of the second radio frame is simultaneously the dynamic PDSCH transmission and the first slot n+1 of the second radio frame. The feedback position of the dynamic PDSCH transmission in the slot n+3 of the two radio frames, and the DAI carried in the dynamic PDSCH transmission in the slot n+3 of the second radio frame is 2, then the HARQ-ACK codebook of the slot n+4 The size is 3.

It should be noted that the slot for resending the SPS PDSCH reconfiguration information in FIG. 3b is only an example, and the network side device may resend the SPS in any slot after the slot n+3 of the first radio frame according to actual conditions. The PDSCH activation information, for example, the network side device may resend the SPS PDSCH activation information in the slot n+5 of the first radio frame, but is not limited thereto.

It should be understood that, for an application scenario in which the network side device sends the SPS PDSCH reconfiguration information to the user equipment, if the SPS PDSCH reconfiguration information does not indicate changing the time domain location of the SPS PDSCH transmission and/or the HARQ feedback timing of the SPS PDSCH transmission, the indication When the frequency domain location or MCS of the SPS PDSCH is changed, the network side device can still transmit and receive according to the SPS PDSCH transmission position and feedback timing before the SPS reconfiguration information is transmitted.

In the embodiment of the present disclosure, if the network side device sends the SPS PDSCH reconfiguration information to the user equipment, and the SPS PDSCH reconfiguration information indicates to change the time domain location of the SPS PDSCH transmission and/or the HARQ feedback timing of the SPS PDSCH transmission, The HARQ feedback corresponding to the SPS PDSCH reconfiguration information is earlier than the HARQ feedback corresponding to the SPS PDSCH transmission after the SPS PDSCH reconfiguration information.

Therefore, it can be avoided that the network side device and the UE have different understandings of the HARQ feedback codebook size corresponding to the feedback position of the SPS PDSCH transmission after the SPS PDSCH reconfiguration information, thereby improving system data transmission performance.

For ease of understanding, please refer to Figure 4a and Figure 4b together. In FIG. 4a and FIG. 4b, the network side device sends SPS PDSCH activation information in slot n, indicating that the HARQ feedback timing of the SPS PDSCH is 4, and the SPS PDSCH reconfiguration information is sent in slot n+5, and the base station cannot indicate other dynamics. The PDSCH transmission and the SPS PDSCH reconfiguration information transmitted in the slot n+5 perform HARQ feedback at the same location, and it is necessary to ensure that the HARQ feedback indicated by the SPS PDSCH reconfiguration information is earlier than the SPS PDSCH transmission after the SPS PDSCH reconfiguration information. Corresponding HARQ feedback.

As shown in FIG. 4a, assuming that a single codeword transmission mode is used on the current carrier, the network side device transmits the SPS PDSCH reconfiguration information in slot n+5, and the HARQ feedback time of the SPS PDSCH reconfiguration information must be after the SPS PDSCH reconfiguration information. The SPS PDSCH transmission, that is, the feedback position corresponding to the SPS PDSCH transmission of slot n+6 in the first radio frame in FIG. 4a, that is, before the slot n of the second radio frame.

It is assumed that the HARQ feedback timing indicated by the SPS PDSCH reconfiguration information is 4. If the network side device does not receive feedback from the UE on the SPS PDSCH reconfiguration information in the slot n+9 of the first radio frame, that is, DTX is detected, It is determined that the SPS PDSCH reconfiguration information is not correctly received by the UE, and the network side device still transmits and receives according to the SPS PDSCH transmission position and feedback timing before the SPS reconfiguration information is transmitted. It should be understood that for the transmission opportunity of the SPS PDSCH reconfiguration information, the transmission opportunity of the feedback information of the slot n+5 to the SPS PDSCH reconfiguration information of the first radio frame, such as the slot n+9 of the first radio frame. Between the SPS PDSCH transmission opportunities before the SPS reconfiguration information is transmitted, the network side device may autonomously select to perform SPS PDSCH transmission in the SPS PDSCH transmission opportunity, or may not select to perform SPS PDSCH transmission.

For example, in the slot n+6 of the first radio frame, the network side device may select not to transmit the SPS PDSCH, but the UE does not receive the SPS PDSCH reconfiguration information sent in the slot n+5 of the first radio frame. Next, slot n+6 of the first radio frame is still considered to be an SPS PDSCH transmission opportunity, and an ACK or NACK is fed back in the slot n of the second radio frame. The network side device also considers that the slot n of the second radio frame is the feedback position corresponding to the SPS PDSCH transmission of the slot n+6 of the first radio frame, and the HARQ feedback codebook corresponding to the slot n of the second radio frame is The codebook size determined according to the DAI is incremented by 1, that is, the HARQ feedback codebook size in the slot n of the second radio frame is 3.

As shown in FIG. 4b, assuming that a single codeword transmission mode is used on the current carrier, the base station transmits the SPS PDSCH reconfiguration information in slot n+5, and the HARQ-ACK feedback time indicated by the base station must be in the second radio frame. Before slot n.

It is assumed that the HARQ feedback timing indicated by the SPS PDSCH reconfiguration information is 4, and if the network side device receives the ACK/NACK of the feedback of the SPS PDSCH reconfiguration information by the terminal in the slot n+9 of the first radio frame, the SPS PDSCH is considered to be heavy. The configuration information is correctly received by the UE, and the network side device transmits and receives according to the SPSPDSCH transmission position and the feedback timing indicated by the SPS PDSCH reconfiguration information.

For example, the base station considers that the slot n in the second radio frame is no longer the feedback position corresponding to the SPS PDSCH transmission, that is, the HARQ feedback codebook size in the slot n of the second radio frame is 2. The network side device considers that the slot n+1 of the second radio frame is a new SPS PDSCH transmission position, and the corresponding feedback position is in the slot n+5 of the second radio frame, and the corresponding HARQ-ACK feedback codebook is based on The codebook size determined by the DAI is incremented by 1, that is, the HARQ-ACK feedback codebook size in the slot n+5 of the next radio frame is 4.

In summary, the semi-persistent scheduling transmission method of the embodiment sends a semi-persistent scheduling physical downlink shared channel SPS PDSCH activation or reconfiguration information to the user equipment; the hybrid automatic retransmission request HARQ feedback of the SPS PDSCH activation or reconfiguration information The information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions, which can ensure that the network side device and the UE have a consistent understanding of the feedback codebook size corresponding to the feedback position of the SPS PDSCH transmission, and can ensure that the SPS transmission is activated or reconfigured. In the case of correct transmission of HARQ feedback information, the system data transmission performance can be improved.

It should be noted that the various optional embodiments described in the embodiments of the present disclosure may be implemented in combination with each other, or may be implemented separately, and the embodiments of the present disclosure are not limited thereto.

Referring to FIG. 5, FIG. 5 is a flowchart of a second semi-persistent scheduling transmission method according to an embodiment of the present disclosure, which is applied to a network side device. The main differences between the embodiment and the embodiment corresponding to FIG. 1 are:

For example, in the embodiment corresponding to FIG. 1, the hybrid automatic repeat request HARQ feedback information of the SPS PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission are transmitted at different feedback positions.

However, in this embodiment, the hybrid automatic repeat request HARQ feedback information of the SPS PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission may be transmitted at the same feedback position.

Second, in the embodiment corresponding to FIG. 1, the UE feeds back an ACK or a NACK at the feedback position of the SPS PDSCH transmission, and both the UE and the network side device consider that the HARQ feedback codebook corresponding to the feedback position includes 1-bit SPS PDSCH feedback. Information: The UE feeds back the NTX at the feedback position of the SPS PDSCH transmission, and both the UE and the network side device consider that the HARQ feedback codebook corresponding to the feedback location does not include 1-bit SPS PDSCH feedback information.

However, in this embodiment, the UE feeds back an ACK at the feedback position of the SPS PDSCH transmission, and both the UE and the network side device consider that the HARQ feedback codebook corresponding to the feedback location includes 1-bit SPS PDSCH feedback information; the UE transmits in the SPS PDSCH. The NQ or NTX is fed back to the feedback location. The UE and the network side device both consider that the HARQ feedback codebook corresponding to the feedback location does not include 1-bit SPS PDSCH feedback information.

As shown in FIG. 5, the semi-persistent scheduling transmission method of this embodiment includes the following steps:

501. The network side device sends a semi-persistent scheduling physical downlink shared channel SPS PDSCH activation or reconfiguration information to the user equipment.

502. The user equipment receives the semi-persistent scheduling physical downlink shared channel SPS PDSCH activation or reconfiguration information sent by the network side device.

503. The user equipment sends the hybrid automatic repeat request HARQ feedback information at a feedback position corresponding to the SPS PDSCH activation or reconfiguration information.

504. The network side device receives the hybrid automatic repeat request HARQ feedback information of the user equipment at a feedback position corresponding to the SPS PDSCH activation or reconfiguration information.

505. If the HARQ feedback information is a positive acknowledgment ACK, the user equipment determines that the HARQ feedback codebook sent in the feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information; or, if the HARQ feedback information is negative In response to the NACK or the discontinuous transmission of the DTX, the user equipment determines that the 1-bit SPS PDSCH feedback information is not included in the HARQ feedback codebook transmitted at the feedback position of the SPS PDSCH transmission.

506. If the HARQ feedback information is a positive acknowledgment ACK, the network side device determines that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information; or, if the HARQ feedback information is If the NACK is negatively acknowledged or the DTX is not continuously transmitted, the network side device determines that the SPS PDSCH feedback information of the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission does not include one bit.

Specifically, in the scenario in which the network side device sends the SPS PDSCH activation information to the user equipment, the HARQ feedback information of the user equipment is received at a feedback position corresponding to the SPS PDSCH activation information. If the HARQ feedback information is ACK, the feedback position of the SPS PDSCH transmission may be determined according to the SPS PDSCH feedback timing indicated by the SPS PDSCH activation information. Of course, if the SPS PDSCH activation information does not include the indication field of the SPS PDSCH feedback timing, the feedback location of the SPS PDSCH transmission may be determined according to the predefined or pre-configured SPS PDSCH feedback timing, which may be determined according to actual needs, and the embodiment of the present disclosure is This is not limited.

In a scenario in which the network side device sends the SPS PDSCH reconfiguration information to the user equipment, the HARQ feedback information of the user equipment is received at a feedback position corresponding to the SPS PDSCH reconfiguration information. If the HARQ feedback information is ACK, the feedback position of the SPS PDSCH transmission is determined according to the SPS PDSCH feedback timing indicated by the SPS PDSCH reconfiguration information; if the HARQ feedback information is NACK or DTX, the feedback position of the SPS PDSCH transmission is activated according to the SPS PDSCH. The SPS PDSCH feedback timing determination indicated by the information, or the SPS PDSCH feedback timing indicated by the SPS PDSCH reconfiguration information successfully received by the UE before the SPS PDSCH reconfiguration information is determined.

It should be noted that, in this embodiment, the hybrid automatic repeat request HARQ feedback information of the SPS PDSCH activation or reconfiguration information and the HARQ feedback information of the dynamic PDSCH transmission may be transmitted in the same different feedback position. Different feedback position transmissions. In this way, the network side device can accurately distinguish whether the UE feeds back an ACK or a NACK or DTX.

Therefore, in this embodiment, if the HARQ feedback information is a positive acknowledgment ACK, the network side device and the UE may determine that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information; if HARQ The feedback information is a negative acknowledgement NACK or a discontinuous transmission DTX, and the network side device and the UE may determine that the SPS PDSCH feedback information is not included in the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission.

It should be noted that the implementation manner of this embodiment is similar to the implementation manner of the method embodiment corresponding to FIG. 1 . For details, refer to the description in the foregoing method embodiments. To avoid repetition, details are not described herein again.

Scenario 3: The network side device sends the SPS PDSCH activation information to the user equipment.

For ease of understanding, it is assumed that the transmission interval of the SPS PDSCH pre-configured by the RRC signaling is 6 slots, and the network side device transmits one SPS PDSCH activation information in the slot n of the first radio frame, and the SPS HARQ indicated by the SPS PDSCH activation information. The feedback timing is 4.

Please refer to Figure 6a and Figure 6b together. As shown in FIG. 6a, the feedback information of the SPS PDSCH activation information detected by the network side device in the slot n+4 of the first radio frame is ACK, and the UE correctly receives the SPS PDSCH activation information. Both the network side device and the UE consider that the HARQ feedback code corresponding to the feedback position of the subsequent SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, such as slot n+6 in the first radio frame and slot in the second radio frame. The SPS PDSCH in n+2 transmits the corresponding HARQ feedback position, that is, the slot 1 of the second radio frame and the HARQ codebook of the slot n+6 of the second radio frame contain 1-bit SPS PDSCH feedback information. Assuming that the single codeword transmission mode is used on the current carrier, the size of the HARQ-ACK codebook in the slot n of the second radio frame is 3, and the size of the HARQ-ACK codebook in the slot n+6 in the second radio frame is 4.

As shown in FIG. 6b, when the network side device receives the feedback information of the SPS PDCCH activation information transmitted by the UE to the slot n in the slot n+4 of the first radio frame, which is NACK or DTX, the UE considers that the SPS PDCCH activation is not correctly received. information. Both the network side device and the UE consider that the HARQ feedback code corresponding to the feedback position of the subsequent SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information. Assuming that the single codeword transmission mode is used on the current carrier, the HARQ-ACK codebook size in the slot n of the second radio frame is considered to be three.

As shown in FIG. 6b, it is assumed that the network side device resends the SPS PDSCH activation information in the slot n+6 of the first radio frame, and the network side device detects that the UE retransmits in the slot n of the second radio frame. The feedback ACK of the SPS PDSCH activation information is considered to be the feedback position corresponding to the SPS PDSCH transmission in the slot n+6 of the second radio frame, and the corresponding HARQ-ACK feedback codebook is the codebook size determined according to the DAI plus 1, that is, The HARQ-ACK feedback codebook size in slot n+6 of the next radio frame is 3.

Scenario 4: The network side device sends SPS PDSCH reconfiguration information to the user equipment.

If the first feedback position and the second feedback position are different, the optional step 506 may be:

or,

Step 505 can be specifically expressed as:

or,

As shown in FIG. 7a, it is assumed that the single-codeword transmission mode is used on the current carrier, and the SPS PDSCH reconfiguration information sent by the network side device in the slot n of the first radio frame is due to the slot n+ in the first radio frame. 1 and the dynamic SPS PDSCH transmission sent in slot n+2 of the first radio frame includes DAI, and the UE may not receive the SPS PDSCH reconfiguration information, so the network side device considers the slot in the first radio frame. The nQ3 feedback code of the n+3 does not need to include the feedback information of the 1-bit SPS transmission, and the size of the HARQ-ACK feedback codebook corresponding to the slot n+3 of the first radio frame is 2.

If the network side device receives the ACK of the UE feedback on the SPS PDSCH reconfiguration information in the slot n+3 of the first radio frame, it is considered that the SPS PDSCH reconfiguration information has been correctly received by the UE.

The network side device and the UE may determine that the HARQ feedback code corresponding to the fourth feedback position of the SPS PDSCH transmission does not include the 1-bit SPS PDSCH feedback information, and the slot n+4 in the first radio frame is taken as an example. The size of the HARQ feedback codebook corresponding to n+4 is 1.

The network side device and the UE may determine that the HARQ feedback code corresponding to the third feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, and transmit the corresponding feedback position by using the SPS PDSCH in the slot n+6 of the first radio frame. For example, the slot n+9 of the first radio frame is taken as an example, and the size of the HARQ feedback codebook corresponding to the slot n+9 is 2. And the second feedback position corresponding to the SPS PDSCH transmission of the slot n+6 of the first radio frame determined by the HARQ feedback timing before the SPS PDSCH reconfiguration information is sent, that is, the slot n of the second radio frame, the network side device may And determining that the corresponding HARQ feedback codebook in the slot n includes 1-bit SPS PDSCH feedback information, and the size of the HARQ-ACK feedback codebook corresponding to the slot n is 1.

As shown in FIG. 7b, it is assumed that the single-codeword transmission mode is used on the current carrier, and the SPS PDSCH reconfiguration information sent by the network side device in the slot n of the first radio frame is due to the slot n+ in the first radio frame. 1 and the dynamic SPS PDSCH transmission sent in slot n+2 of the first radio frame includes DAI, and the UE may not receive the SPS PDSCH reconfiguration information, so the network side device considers the slot in the first radio frame. The nQ3 feedback code of the n+3 does not need to include the feedback information of the 1-bit SPS transmission, and the size of the HARQ-ACK feedback codebook corresponding to the slot n+3 of the first radio frame is 2.

If the network side device detects that the UE feedback information for the SPS PDSCH reconfiguration information is NACK or DTX in the slot n+3 of the first radio frame, it is considered that the SPS PDSCH reconfiguration information is not correctly received by the UE.

The network side device and the UE may determine that the one-bit SPS PDSCH feedback information is not included in the HARQ feedback codebook corresponding to the third feedback position of the SPS PDSCH transmission.

The network side device and the UE may determine that the HARQ feedback codebook corresponding to the fourth feedback position of the SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information, and the slot n+4 of the first radio frame is taken as an example, then the slot n+ 4 The corresponding HARQ-ACK feedback codebook size is 2.

The network side device may resend the SPS PDSCH reconfiguration information in the slot n+6 of the first radio frame, and the feedback position of the SPS PDSCH reconfiguration information, that is, the slot n+9 of the first radio frame does not include the 1-bit SPS. For the PDSCH feedback information, the corresponding HARQ-ACK feedback codebook size is 2.

It is assumed that the network side device detects the ACK of the feedback of the SPS PDSCH reconfiguration information by the UE in the slot n+9 of the first radio frame, and the network side device and the UE consider the SPS PDSCH transmission of the slot n+6 of the first radio frame. The feedback position code corresponding to the slot n of the second radio frame does not include the 1-bit SPS PDSCH feedback information, and the size of the HARQ-ACK feedback codebook corresponding to the slot n is 1.

In addition, the network side device and the UE may determine that the HARQ feedback codebook corresponding to the third feedback position of the subsequent SPS PDSCH transmission includes 1-bit SPS PDSCH feedback information. Taking slot n+5 of the second radio frame as an example, the HARQ feedback codebook corresponding to slot n+5 of the second radio frame includes 1-bit SPS PDSCH feedback information, and the corresponding HARQ-ACK feedback codebook is The size of the codebook determined according to the DAI is increased by 1, that is, the size of the HARQ-ACK feedback codebook in the slot n+5 of the second radio frame is 3.

As described above, in the semi-persistent scheduling transmission method of the present embodiment, if the HARQ feedback information is a positive acknowledgment ACK, the network side device and the UE determine that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission includes a 1-bit SPS. The PDSCH feedback information; if the HARQ feedback information is a negative acknowledgement NACK or a discontinuous transmission DTX, it is determined that the HARQ feedback codebook received at the feedback position of the SPS PDSCH transmission does not include the 1-bit SPS PDSCH feedback information, thereby ensuring the network side device The UE has a consistent understanding of the feedback codebook size corresponding to the feedback position of the SPS PDSCH transmission, and can ensure that the HARQ feedback information is correctly transmitted in the case of activating or reconfiguring the SPS transmission, thereby improving the system data transmission performance.
