Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, a schematic diagram of a 5G network architecture is shown, where the 5G network architecture mainly includes the following network entity functions:

radio Access Network (RAN): the network, which is composed of at least one 5G-RAN node, implements wireless physical layer functions, resource scheduling and wireless resource management, radio access control, and mobility management functions. The 5G-RAN is connected with the UPF through a user plane interface N3 and is used for transmitting data of the terminal equipment; the 5G-RAN establishes a control plane signaling connection with the AMF through the control plane interface N2, and is used to implement functions such as radio access bearer control. The 5G-RAN Node may specifically be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) System or a Code Division Multiple Access (CDMA) System, may also be a Base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA) System, may also be an evolved Node B (eNB) in an LTE System, or may also be a Base Station device, a small Base Station device, a wireless Access Node (WiFi AP) in a future 5G network, and the present application is not limited thereto.

Access and Mobility Management Function (AMF): the method is mainly responsible for authentication of User Equipment (UE), mobility management of the UE, selection of network slices, selection of SMF and other functions. The AMF serves as an anchor point for the N1 and N2 signaling connections and provides the Session Management Function (SMF) with the routing of the N1/N2SM messages. The AMF maintains and manages state information of the UE.

SMF: all control Plane functions mainly responsible for UE session management include User Plane Function (UPF) selection, Internet Protocol (IP) address allocation, Quality of Service (QoS) management of a session, and acquisition of PCC policy from PCF.

User Plane Function (UPF): the serving as an anchor point of a Protocol Data Unit (PDU) session connection is responsible for filtering Data packets, transmitting/forwarding Data, controlling rate, generating charging information, and the like of a user equipment.

A Terminal device may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), and so on, and optionally, the Terminal may have a capability of communicating with one or more core networks via a Radio Access Network (RAN), for example, the Terminal may be a Mobile phone (or referred to as a "cellular" phone), a computer with Mobile property, and so on, for example, the Terminal may also be a portable, pocket, hand-held, computer-embedded, or vehicle-mounted Mobile device.

In a Long Term Evolution (LTE) system, only semi-static (semi-static) HARQ-ACK (Hybrid Automatic Repeat reQuest) transmission is supported, and a timing (i.e., HARQ-ACK timing) between HARQ-ACK feedback of one downlink transmission and the downlink transmission is predefined. For example, for a Frequency Division Duplex (FDD) carrier, the HARQ-ACK for downlink transmission in subframe n-4 is fed back in subframe n, and for a Time Division Duplex (TDD) carrier, for different TDD uplink and downlink configurations, one uplink subframe n correspondingly feeds back the HARQ-ACK for downlink transmission in one downlink subframe set n-K, where K belongs to K, and 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.

In the 5G NR system, two HARQ-ACK timing types, namely semi-static (semi-static) and dynamic (dynamic), are supported, that is, a timing relationship (i.e., HARQ-ACK timing) between HARQ-ACK feedback of one Downlink transmission and the Downlink transmission may be predefined or preconfigured by higher layer signaling, or may be notified in Downlink Control Information (DCI) used by PDCCH. Alternatively, it may also be dynamically changed between a plurality of candidate values pre-configured by the indication of DCI, i.e. dynamic HARQ-ACK timing. Cross slot (slot) scheduling is supported in the 5G NR, that is, a PDCCH transmitted in slot n may schedule PDSCH transmission in slot n, or may schedule PDSCH transmission in slot n + k, where k is greater than 0. Therefore, the DCI used by a PDCCH for scheduling a 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 HARQ-ACK timing of the PDSCH scheduled by the PDCCH.

In the 5G NR system, Semi-Persistent Scheduling (SPS) PDSCH transmission and PDSCH with corresponding PDCCH (i.e., dynamic PDSCH) transmission are also supported. When the SPS PDSCH service is configured, the higher layer signaling configures a Radio Network Temporary Identifier (RNTI) corresponding to the SPS correspondingly, and is used to scramble the PDCCH for the SPS PDSCH, and the higher layer signaling also configures a transmission interval of the SPS PDSCH correspondingly.

Wherein the HARQ-ACK timing for PDSCH with PDCCH (i.e., dynamic PDSCH) may be indicated by the HARQ-ACK timing indication field in PDCCH, e.g., one of 8 candidate HARQ-ACK timing preconfigured for higher layer signaling may be indicated for the 3-bit indication field, which may be dynamically changed for each PDSCH transmission, and is therefore referred to as dynamic HARQ-ACK timing. Under dynamic HARQ-ACK timing, two HARQ-ACK codebook (codebook) generation methods including semi-static and dynamic are included. The HARQ-ACK codebook is a HARQ-ACK feedback sequence generated by downlink transmission for HARQ-ACK feedback at the same time domain position.

Currently, in the 5G NR, how to transmit HARQ-ACK timing, resource location, etc. corresponding to SPS PDSCH is not clear.

In view of this, embodiments of the present application provide a transmission method and a device for HARQ-ACK after activation, so as to keep the feedback time domain position of HARQ-ACK corresponding to SPS PDSCH transmission unchanged after activation, and further ensure that the terminal and the network side understand the feedback content of HARQ-ACK consistently, thereby implementing HARQ-ACK transmission in a 5G network architecture.

The embodiment of the application can be applied to a 5G Communication System, and the 5G Communication System can be applied to applications in various industries, such as mobile broadband, multimedia, Machine Type Communication (MTC), industrial control, and Intelligent Transportation System (ITS).

As shown in fig. 2, the present application provides a schematic diagram of a network architecture that may be suitable for use. The network architecture includes a network-side device 21 and a terminal device 22. The network side equipment is the network side equipment of the terminal equipment which is accessed to the communication currently.

The terminal in the application can be a device with a wireless communication function, and can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). For example, the terminal in the present application may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving, a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like; but also UE in various forms, Mobile Station (MS), terminal equipment (terminal device). The UE in fig. 1 is a specific example of a terminal device of the present application.

The network side device in this application may be a base station, and includes a device for providing a wireless communication function for a terminal, including but not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home Base Station (e.g., home evolved Node B or home Node B, HNB), a baseband Unit (Base Band Unit, BBU), a transmission Point (TRP), a Transmission Point (TP), a mobile switching center, and the like. The base station in the present application may also be a device that provides a terminal with a wireless communication function in other communication systems that may appear in the future.

As shown in fig. 3, a method for transmitting a hybrid automatic repeat request response provided in an embodiment of the present application includes:

step 301, the network side device 21 determines the PDCCH scrambled by the first RNTI and sends the PDCCH scrambled by the first RNTI to the terminal device 22, so that the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH scrambled by the first RNTI is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH indicating activation of the SPS PDSCH;

optionally, the time domain position in this embodiment of the present application at least includes a time slot position or a time slot number.

Optionally, the first RNTI in the embodiment of the present application includes: RNTI or C-RNTI corresponding to SPS.

In particular, the SPS C-RNTI is used to identify the PDCCH corresponding to SPS traffic. For example, a PDCCH for indicating SPS resource activation, a PDCCH for indicating updating/resetting of SPS PDSCH transmission configuration. The RNTI corresponding to the SPS includes a Configured scheduled radio network temporary identity (CS-RNTI).

S302, the terminal device 302 receives the PDCCH scrambled by the first RNTI and sends the HARQ-ACK of the SPS PDSCH according to the PDCCH scrambled by the first RNTI.

It should be noted that, in the transmission method of the harq response provided in the embodiment of the present application, the default is performed when the SPS PDSCH corresponding to the terminal device is in an active state. Specifically, the SPS PDSCH being in an active state includes: when the terminal equipment receives a PDCCH indicating activation of the downlink SPS resources, the subsequent SPS transmission opportunities determined according to the PDCCH are all in an activated state; wherein, the subsequent SPS transmission opportunity in the embodiment of the present application does not include the first PDSCH transmission corresponding to the PDCCH. For example, if the PDCCH is sent in slot N and the scheduling timing is k, determining that one PDSCH transmission in slot N + k is scheduled, where slot N + k is not included in a subsequent SPS transmission opportunity determined according to the PDCCH, and the subsequent SPS transmission opportunity includes a slot start (e.g., slot N + k + N) that is N slots apart from slot N + k, where N is greater than 0.

Optionally, the SPS PDSCH in the embodiment of the present application may be one of the following PDCCHs:

PDSCH without corresponding PDCCH;

an SPS PDSCH transmitted in a subsequent SPS transmission opportunity determined from a PDCCH indicating downlink SPS activation;

an SPS PDSCH transmitted in a subsequent SPS transmission opportunity determined from a PDCCH indicating a downlink SPS update/reset.

Specifically, when the SPS PDSCH is transmitted in the SPS transmission opportunity determined in the activation process or in the SPS transmission opportunity determined in the update or reset process, it is required to ensure that the time domain position corresponding to the HARQ-ACK feedback of the SPS PDSCH is not changed, thereby avoiding the problem that the HARQ-ACK feedback content is inconsistent between the terminal and the network side.

Therefore, in the application, after the time domain position of the HARQ-ACK corresponding to the SPS PDSCH determined by the PDCCH scrambled by the first RNTI by the network side equipment and the terminal equipment is the same as the time domain position of the HARQ-ACK corresponding to the SPS PDSCH determined by the PDCCH indicating the activation of the SPS PDSCH, when the HARQ-ACK corresponding to the SPS PDSCH in a subsequent SPS transmission opportunity is transmitted, the problem that the HARQ-ACK feedback positions are different after the SPS is updated or reset, so that the HARQ-ACK codebook understanding of the terminal and the network side is inconsistent is avoided.

Optionally, in the embodiment of the present application, the time domain position of the HARQ-ACK of the SPS PDSCH determined by using the PDCCH scrambled by the first RNTI is determined, and there are various methods the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined by using the PDCCH indicating activation of the SPS PDSCH, and the following description is listed:

the method 1 further ensures that the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH scrambled by using the first RNTI is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH indicating activation of the SPS PDSCH according to the time domain indication domain included in a downlink control information DCI format used by the PDCCH or the feedback time sequence indication domain from the PDSCH to the HARQ-ACK.

Method 1-1, when a DCI format of downlink control information used by a PDCCH includes a time domain indicator, a time domain position of an SPS PDSCH determined according to a scheduling timing indicated by the time domain indicator in the DCI format used by the PDCCH scrambled using the first RNTI is the same as a time domain position of an SPS PDSCH determined according to a scheduling timing indicated by the time domain indicator in the DCI format used by the PDCCH indicating activation of the SPS PDSCH.

Or, when the downlink control information DCI format used by the PDCCH includes a time domain indicator field, the transmission opportunity of the SPS PDSCH determined according to the scheduling timing indicated by the time domain indicator field in the DCI format used by the PDCCH scrambled by using the first RNTI is the same as the transmission opportunity of the SPS PDSCH determined according to the scheduling timing indicated by the time domain indicator field in the DCI format used by the PDCCH indicating activation of the SPS PDSCH.

It should be noted that, in the embodiment of the present application, the scheduling timing indicated by the time domain indicator field in the DCI format refers to the number of time slots between the PDCCH and the scheduled PDSCH. For example, when PDCCH is transmitted in slot n, PDSCH transmission in slot n + K0 may be scheduled, where K0 belongs to one value in a pre-configured or defined set of scheduling timings, indicated by the time domain indicator field in PDCCH.

Method 1-2, when the DCI format used by the PDCCH includes a feedback timing indication field for indicating PDSCH-to-HARQ-ACK timing, the feedback timing indication field in the DCI format used by the PDCCH scrambled using the first RNTI is the same as the content indicated by the feedback timing indication field in the DCI format used by the PDCCH indicating SPS PDSCH activation.

It should be noted that the feedback timing indicated by the feedback timing indication field in the DCI format in the embodiment of the present application refers to the number of slots between the PDSCH and the HARQ-ACK transmission of the PDSCH. For example, when PDSCH is in slot n, HARQ-ACK feedback for PDSCH may be made in slot n + K1, where K1 belongs to one value of a preconfigured or defined set of feedback timings, indicated by the feedback timing indication field in PDCCH.

Specifically, the above methods may be used alone or in combination; when a time domain indication domain or a feedback timing indication domain of the PDSCH to HARQ-ACK timing included in a downlink control information DCI format used by the PDCCH:

for example, if the PDCCH indicating the SPS update and SPS activation does not include the feedback timing indication field (i.e. HARQ-ACK timing indication field) of the PDSCH-to-HARQ-ACK timing but includes the time domain indication field, the same pre-configured or agreed HARQ-ACK timing is used, so that the HARQ-ACK timing corresponding to the PDCCH indicating SPS update and activation is itself the same, to ensure that the "time domain position (e.g., slot position, but of course also specific symbol position, the same applies below) of the HARQ-ACK for SPS PDSCH determined from PDCCH scrambled with the first RNTI, the same as the time domain position of HARQ-ACK of SPS PDSCH determined according to PDCCH indicating SPS PDSCH activation, it is only necessary to guarantee the time domain position of the PDSCH determined according to the scheduling timing indicated by the time domain indication field in the scrambled PDCCH using the first RNTI, the time domain position of the PDSCH is the same as the time domain position of the PDSCH determined according to the scheduling timing indicated by the time domain indication domain in the PDCCH for indicating the activation of the SPS PDSCH. For example, the SPS may be updated and activated with the same scheduling timing and the same PDCCH transmission location; or, different PDCCH transmission positions and different scheduling timings are adopted when the SPS is updated and activated, but the time domain positions where the PDSCH is transmitted and determined by the scheduling timings are the same, that is, the transmission opportunities after the SPS is updated and when the SPS is activated are guaranteed to be the same, so that the same time domain feedback position (for example, the same slot) is determined according to the same HARQ-ACK timing, and the same time domain feedback position is guaranteed.

If the PDCCH for indicating updating of the SPS and indicating activation of the SPS comprises a HARQ-ACK timing indication domain but does not comprise a time domain indication domain, using the same pre-configured scheduling timing, namely the scheduling timing corresponding to the PDCCH for indicating updating of the SPS and activating of the SPS is the same, and if the PDCCH for indicating updating of the SPS and activating of the SPS is sent at the same time and the same PDSCH transmission time is determined, the SPS transmission opportunities for indicating updating of the SPS and activating of the SPS are the same; in order to ensure that the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH scrambled by using the first RNTI is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH for indicating activation of the SPS PDSCH, the timing of the indication SPS updating and the activated HARQ-ACK is also required to be ensured to be the same, namely the same feedback position is ensured; or, if the PDCCH indicating the SPS update and the activated SPS is transmitted at different times, the PDSCH indicating the SPS update and the activated PDSCH are determined to be transmitted at different times, and in order to ensure that "the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH scrambled using the first RNTI is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the PDCCH indicating the SPS PDSCH activated", it is also required to ensure that the HARQ-ACK timing indicating the SPS update and the activated PDSCH are different, so as to ensure the same feedback position.

If the PDCCHs for indicating updating the SPS and indicating activating the SPS do not contain the HARQ-ACK timing indication domain or the time domain indication domain, the same preset scheduling timing and the same HARQ-ACK timing are used, and the fact that the PDCCH for indicating updating the SPS and the activated SPS is sent at the same time is only required to be ensured; at this time, if it is determined that the PDSCH is transmitted at the same time, it is further determined that the transmission opportunities of the SPS during updating and activation are the same, thereby ensuring the same feedback position.

Method 2,

When the DCI format used by the PDCCH comprises a time domain indication domain and a feedback timing indication domain for indicating the PDSCH-to-HARQ-ACK timing, the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the feedback timing indication domain in the DCI format used by the PDCCH scrambled by using the first RNTI and the scheduling timing indicated by the time domain indication domain is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the feedback timing indication domain in the DCI format used by the PDCCH for indicating the activation of the SPS PDSCH and the scheduling timing indicated by the time domain indication domain.

It should be noted that, in the method 1 and the method 2, if it is determined that HARQ-ACK feedback is performed at the same time or on the same uplink control channel, it is also required to determine that the time domain positions of PUCCH resources indicated in the PDCCH are the same, that is, the symbol positions are the same, when the HARQ-ACK feedback time domain positions determined according to the SPS transmission opportunity and the HARQ-ACK timing are the same; of course, the HARQ-ACK feedback may be performed in the same slot without this limitation.

To further illustrate the above-described methods provided by embodiments of the present invention, the steps of the above-described methods are illustrated below by specific examples. In this embodiment, only 10 slots are included in one radio frame for example.

As shown in fig. 4, the UE has received a PDCCH scrambled with an RNTI (e.g., CS-RNTI, Configured Scheduling RNTI) corresponding to the SPS before slot n and having an NDI of 0, where the PDCCH instructs the UE to activate downlink SPS service transmission, and determines that a subsequent SPS transmission opportunity is slot +1 in each radio frame according to Scheduling timing in the PDCCH and a SPS transmission interval (e.g., 10 slots) pre-Configured by a higher layer signaling, and the SPS HARQ-ACK timing indicated in the activated PDCCH is 3, that is, a PDSCH transmitted in slot x performs HARQ-ACK feedback at slot x +3, an SPS PDSCH in slot n +1 needs to feedback HARQ-ACK in slot n +4, and there are other PDSCHs having corresponding PDCCHs in slot n +4 and perform HARQ-ACK feedback together with an SPS PDSCH in slot n + 1. In fig. 4, other PDSCHs having corresponding PDCCHs are referred to as dynamic PDSCHs, and the number of PDSCHs scheduled with a plurality of corresponding PDCCHs and PDCCHs indicating release of Downlink SPS resources up to now are counted by the value of a Downlink Assignment Index (DAI), which can be used to obtain HARQ-ACK codebooks corresponding to these transmissions. Since the DAI does not include the count information of the SPS PDSCH without the corresponding PDCCH, the SPS HARQ-ACK needs to be added to the first HARQ-ACK codebook determined according to the DAI in slot n + 4. For example, assuming that each PDSCH corresponds to 1-bit HARQ-ACK, 2-bit first HARQ-ACK codebook and 1-bit SPS HARQ-ACK need to be fed back in slot n +4, for a total of 3-bit HARQ-ACK. The PDSCH performing HARQ-ACK feedback in slot n +9 does not include SPS PDSCH, so that SPS HARQ-ACK does not need to be added to the first HARQ-ACK codebook generated based on DAI in slot n +9, namely the first 4-bit HARQ-ACK codebook is directly generated according to DAI for transmission. In the next radio frame, processed in a similar way, SPS HARQ-ACK always needs to be added in the first HARQ-ACK codebook in slot n +4, while SPS HARQ-ACK does not need to be added in slot n + 9.

When the base station needs to send a PDCCH indicating the configuration of SPS transmission to be updated, the PDCCH may be sent in a slot, where the PDCCH is scrambled with an RNTI (e.g., CS-RNTI, Configured Scheduling RNTI) corresponding to the SPS and has an NDI of 0, and since the UE is already in the SPS active state, the PDCCH may indicate the UE to update the configuration of the activated downlink SPS transmission, including various information such as update transmission opportunity, frequency domain resource, Modulation and Coding Scheme (MCS) level, and HARQ-ACK timing. When the base station updates the configuration of downlink SPS transmission through the PDCCH, in order to avoid the inconsistency of understanding of HARQ-ACK transmitted in each UL slot by the base station and the terminal and avoid the wrong HARQ-ACK transmission and analysis of the base station and the terminal, the HARQ-ACK feedback of the SPS before and after updating needs to be ensured at the same time.

The above-described method 1 is explained below by way of example:

it is required to ensure that the subsequent SPS transmission opportunity determined from the PDCCH indicating SPS update coincides with the subsequent SPS transmission opportunity determined from the PDCCH indicating SPS activation, and that the HARQ-ACK timing indicated by the PDCCH indicating SPS update is the same as the HARQ-ACK timing indicated by the PDCCH indicating SPS activation. As shown in fig. 5A or fig. 5B, for example, a PDCCH indicating SPS update is transmitted in slot n + x, where scheduling timing indicates PDSCH transmission in slot n +1 of radio frame i, and HARQ-ACK timing indicated by the PDCCH indicating SPS update is 3 (i.e., the same as HARQ-ACK timing indicated by the PDCCH indicating SPS activation). Wherein x may be equal to 1 or less than 1. For example, if x is 1, the scheduling timing is 0, i.e. the slot scheduling; for another example, if x is 0, then scheduling timing is 1, i.e., PDSCH in slot n +0+1 is scheduled; the SPS transmission opportunity and HARQ-ACK timing determined according to the PDCCH indicating SPS updating are the same as the original SPS, and the PDCCH indicating SPS updating may only change information such as MCS, frequency domain resource position/size, and the like of the SPS, so that the updated SPS transmission opportunity is also slot n +1 in each radio frame, and the corresponding HARQ-ACK feedback position is also slot n +4 in each radio frame.

Situation one,

If the UE does not receive the PDCCH indicating updating of the SPS in slot n +1 of the wireless frame i:

the UE side: generating NACK for slot n +1 position according to DAI and generating 2-bit first HARQ-ACK codebook transmitted in slot n +4 according to DAI as the PDCCH contains DAI; at this time, the UE still works according to the original SPS transmission opportunity and transmission configuration without receiving the SPS update instruction, as shown in fig. 5A, that is, the UE receives the SPS PDSCH in slot n +1 according to the SPS resources originally configured, generates 1-bit SPS HARQ-ACK, adds the 1-bit SPS HARQ-ACK to the first HARQ-ACK codebook, thereby obtaining 3-bit HARQ-ACK feedback information, and transmits the feedback information in slot n + 4.

A base station side: according to the understanding of the PDCCH which indicates the updating of the SPS, the SPS PDSCH is sent in the slot n +1 according to the updated SPS configuration instead of the original SPS configuration, namely HARQ-ACK of the SPS PDSCH using new frequency domain resources/MCS levels in the slot n +1, and the HARQ-ACK of the updated SPS PDSCH is added in the slot n +4 by the terminal, so that the HARQ-ACK feedback information according to 3 bits is also determined to be received in the slot n +4, and a first HARQ-ACK codebook with 2 bits and a SPS HARQ-ACK with 1 bit are obtained, as shown in FIG. 5B; therefore, even if the UE loses the PDCCH indicating SPS update, the reception of HARQ-ACK by the base station is not affected; the only difference is that for the inconsistent understanding of the 1-bit SPS HARQ-ACK, the terminal sends the HARQ-ACK of the original SPS, because the actual base station updates the SPS configuration, the base station will transmit the SPS PDSCH according to the new resource configuration, and the terminal will not correctly receive the SPS PDSCH when receiving the SPS PDSCH on the original SPS resource, so the 1-bit NACK obtained by the terminal is used as the HARQ-ACK of the original SPS, and the base station actually considers the received 1-bit SPS HARQ-ACK as placeholder information, because the PDSCH in slot n +1 itself is scheduled by the PDCCH indicating SPS update, and has DAI information, and its HARQ-ACK is already included in the first HARQ-ACK codebook according to DAI. Therefore, even if the terminal loses the PDCCH indicating SPS update, the base station does not affect the resolution of HARQ-ACK.

In the next radio frame i +1, if the UE does not receive a PDCCH indicating SPS update in slot n + 1:

the UE side: the execution process of the UE is the same as the execution process described above if the UE does not receive the PDCCH indicating to update the SPS in slot n +1 of radio frame i. Namely: if the UE still receives the SPS PDSCH according to the original SPS configuration, then in slot n +4 of the wireless frame i +1, a 3-bit first HARQ-ACK codebook is generated according to the DAI, and then 1-bit HARQ-ACK of the original SPS PDSCH is added, so that 4-bit HARQ-ACK is obtained and transmitted in slot n +4, as shown in fig. 5A.

A base station side: according to the understanding of the PDCCH which sends the indication SPS update, the SPS PDSCH is sent in slot n +1 according to the updated SPS resource, and the HARQ-ACK of the first HARQ-ACK codebook and the updated SPS PDSCH is determined to be contained in slot n +4, so that the HARQ-ACK is determined to be received in slot n +4 according to 4 bits, and then a 3-bit first HARQ-ACK codebook is obtained, and a 1-bit SPS HARQ-ACK is obtained, as shown in figure 5B; therefore, even if the UE loses the PDCCH indicating the SPS update, the HARQ-ACK receiving of the base station is not influenced because the feedback positions of the SPS HARQ-ACK before and after the update are the same. The only difference is that the base station understands inconsistent understanding of SPS transmission corresponding to 1-bit SPS PDSCH, the base station understands HARQ-ACK of SPS PDSCH transmitted according to updated SPS resources in slot n +1, the terminal understands HARQ-ACK of SPS PDSCH transmitted according to SPS resources before updating in slot n +1, if the UE loses PDCCH for indicating SPS updating, the base station transmits the SPS PDSCH according to information such as new frequency domain resources/MCS and the like, the terminal receives the SPS PDSCH according to the original frequency domain resources/MCS level, the SPS PDSCH received by the terminal cannot be decoded correctly, the feedback information is NACK, the terminal does not receive the SPS PDSCH transmitted according to the updated SPS frequency domain resources/MCS by the base station, the feedback information of the SPS PDSCH is also NACK, and the base station is not influenced to understand the NACK as the feedback information of the updated SPS PDSCH. If the UE receives a PDCCH indicating SPS update in slot n +1, refer to the following execution procedure in case two.

The second case,

If the UE receives the PDCCH indicating SPS update in slot n +1 of radio frame i:

the UE side: determining that the updated subsequent SPS transmission opportunity is the same as the original SPS transmission opportunity according to the PDCCH, and similarly configuring slot n +1 in each wireless frame, namely understanding that slot n +1 of the wireless frame i is the current SPS transmission opportunity, namely slot n +1 is the original SPS, wherein the SPS PDSCH in the subsequent SPS transmission opportunity determined by the PDCCH indicating SPS updating in slot n +1 of the wireless frame i is not contained in slot n +4 of the wireless frame i for HARQ-ACK feedback, and the HARQ-ACK of the PDSCH scheduled by the PDCCH indicating SPS updating is contained in the first HARQ-ACK codebook according to DAI count without additionally generating feedback information; another is that, because the UE receives the PDCCH indicating SPS update in slot n +1 of the radio frame i, it determines that SPS transmission configuration is updated in slot n +1 of the radio frame i, and generates 1-bit updated HARQ-ACK for the SPS PDSCH; as shown in FIG. 5B, no matter how to understand, it is not changed that the UE is already in the SPS active state and 1 SPS HARQ-ACK is included in slot n +4 of the wireless frame i and feedback is required, in slot n +4 of the wireless frame i, HARQ-ACK aiming at the SPS PDSCH needs to be added to the first HARQ-ACK codebook, so that 3-bit HARQ-ACK is obtained.

A base station side: the UE side can understand that the HARQ-ACK with 3 bits can also be determined in slot n +4 of a wireless frame i;

for slot n +1 in the subsequent radio frame i +1, both the terminal and the base station consider transmitting according to the updated SPS.

As can be seen from the above first and second cases in method 1, no matter whether the UE receives the PDCCH indicating SPS update, because the SPS HARQ-ACK feedback positions before and after update are consistent, the state that the UE is already in the SPS activation state and the slot n +4 contains the state that the SPS HARQ-ACK needs to be fed back is not changed, in the slot n +4, the HARQ-ACK aiming at the SPS PDSCH always needs to be added to the first HARQ-ACK codebook, thereby ensuring that the terminal and the base station understand the number of feedback bits consistently.

The above-described method 2 is explained below by way of example:

it is necessary to ensure that the HARQ-ACK feedback position corresponding to the subsequent SPS transmission opportunity determined from the PDCCH indicating SPS updating and the HARQ-ACK timing indicated by the PDCCH indicating SPS updating is the same as the HARQ-ACK feedback position corresponding to the SPS transmission before updating determined from the subsequent SPS transmission opportunity determined from the PDCCH indicating SPS activation and the HARQ-ACK timing indicated by the PDCCH indicating SPS updating.

As shown in fig. 6A, 6B, or 6C, for example, a PDCCH indicating SPS update is transmitted in slot n + x, where scheduling timing indicates PDSCH transmission in slot n (different from SPS transmission opportunities determined from the PDCCH indicating SPS activation), and HARQ-ACK timing indicated by the PDCCH indicating SPS update is 4 (i.e., different from HARQ-ACK timing indicated by the PDCCH indicating SPS activation), where x may be equal to 0 or less than 0. For example, if x is 0, then scheduling timing is 0, i.e., the slot scheduling, and if x is-1, then scheduling timing is 1, i.e., PDSCH in slot n + (-1) +1 is scheduled. Although the above information is different from the information determined according to the PDCCH indicating SPS activation, the SPS transmission opportunity and HARQ-ACK timing change simultaneously, and the final effect is to perform HARQ-ACK feedback in the slot corresponding to the original SPS PDSCH transmission.

Situation one,

If the terminal does not receive the PDCCH indicating SPS update in slot n of the wireless frame i:

the UE side: if the PDCCH contains DAI, generating NACK for slot n position according to DAI, and generating a first HARQ-ACK codebook which needs to be transmitted in slot n +4 by 2 bits according to DAI; at this time, the UE still works according to the original SPS transmission opportunity and transmission configuration without receiving the SPS update instruction, as shown in fig. 6A, that is, the UE receives the SPS PDSCH in slot n +1 according to the SPS resources originally configured, generates 1-bit SPS HARQ-ACK, and adds the 1-bit SPS HARQ-ACK to the first HARQ-ACK codebook, so that the obtained 3-bit HARQ-ACK feedback information is transmitted in slot n + 4.

A base station side: according to the understanding of the PDCCH which indicates the SPS update, the SPS PDSCH is transmitted in the updated SPS transmission opportunity slot n but not transmitted in slot n +1, and the HARQ-ACK of the updated SPS PDSCH is added in slot n +4 by the terminal, namely the HARQ-ACK of the SPS PDSCH in slot n is determined, as shown in FIG. 6B, therefore, the HARQ-ACK is also determined to be received in slot n +4 according to 3 bits, so that a 2-bit first HARQ-ACK codebook is obtained, and a 1-bit SPS HARQ-ACK is obtained; even if the UE loses the PDCCH for indicating the SPS updating, the receiving of the HARQ-ACK by the base station is not influenced; the only difference is that the understanding of 1-bit SPS HARQ-ACK is inconsistent, the terminal sends the HARQ-ACK of the original SPS, because the SPS configuration is updated by the actual base station, the base station can transmit the SPS PDSCH according to the new resource configuration on the new SPS opportunity, and the PDSCH cannot be correctly received when the terminal receives the SPS PDSCH on the original SPS resource, so that the 1-bit NACK obtained by the terminal is taken as the SPS HARQ-ACK, and the base station actually considers the received 1-bit SPS HARQ-ACK as the placeholder information because the PDSCH in slot n +5 is scheduled by the PDCCH indicating the SPS update and has DAI information, and the HARQ-ACK is already contained in the first HARQ-ACK codebook according to the DAI; therefore, even if the terminal loses the PDCCH indicating SPS activation, the base station does not affect the resolution of HARQ-ACK.

In the next radio frame i +1, if the UE does not receive a PDCCH indicating SPS update in slot n:

the UE side: if the UE performs the same procedure as above, or receives the SPS PDSCH according to the original SPS configuration, in slot n +4, a 3-bit first HARQ-ACK codebook is generated according to the DAI, and then 1-bit HARQ-ACK of the original SPS PDSCH is added, so that 4-bit HARQ-ACK is obtained and transmitted in slot n +4, as shown in fig. 6A.

A base station side: according to the understanding of the PDCCH which sends the indication SPS update, the SPS PDSCH is sent in slot n +1 according to the updated SPS resource, and the HARQ-ACK which comprises the first HARQ-ACK codebook and the updated SPS PDSCH is determined to be contained in slot n +4, as shown in figure 6B, therefore, the HARQ-ACK is determined to be received in slot n +4 according to 4 bits, so that a 3-bit first HARQ-ACK codebook is obtained, and a 1-bit SPS HARQ-ACK is obtained; even if the UE loses the PDCCH for indicating the SPS updating, the HARQ-ACK receiving of the base station is not influenced because the feedback positions of the SPS HARQ-ACK before and after the updating are the same; the only difference is that the base station understands the SPS transmission corresponding to the 1-bit SPS PDSCH to be inconsistent, the base station understands the HARQ-ACK of the SPS PDSCH transmitted according to the updated SPS resource in slot n, the terminal understands the HARQ-ACK of the SPS PDSCH transmitted according to the SPS resource before updating in slot n +1, if the UE loses the PDCCH for indicating the SPS updating, the base station transmits the SPS PDSCH according to a new position, the terminal receives the SPS PDSCH at an old position, the SPS PDSCH received by the terminal cannot be decoded correctly, the feedback information is NACK, the terminal does not receive the SPS PDSCH transmitted according to the updated SPS transmission opportunity and configuration, the feedback information of the SPS PDSCH is also NACK, and the base station is not influenced to understand the NACK as the feedback information of the updated SPS PDSCH; if the UE receives a PDCCH indicating SPS update in slot n, referring to the following execution process of receiving the PDCCH;

the second case,

If the UE receives the PDCCH indicating SPS update in slot n of radio frame i:

the UE side: determining the updated subsequent SPS transmission opportunity as slot n in each radio frame according to the PDCCH, i.e. an understanding may be considered as: slot n +1 is also the current SPS transmission opportunity, that is, in slot n +1, the SPS PDSCH in the subsequent SPS transmission opportunity determined according to the PDCCH indicating SPS update in slot n is not included in slot n +4 for HARQ-ACK feedback, the HARQ-ACK of the PDSCH scheduled by the PDCCH indicating SPS update itself is already included in the first HARQ-ACK codebook according to the DAI count, and no additional feedback information needs to be generated, as shown in fig. 6C; another understanding can be considered: since the UE receives the PDCCH indicating SPS update in slot n, it is determined that the base station will not send SPS PDSCH in slot n +1 (i.e. the original SPS has been updated, and the new SPS transmission opportunity is slot n), and there is updated HARQ-ACK of SPS in slot n +4, as shown in fig. 6B; no matter how to understand, the UE is in the SPS activation state, and 1 SPS HARQ-ACK included in slot n +4 needs to be fed back, so that in slot n +4, the HARQ-ACK aiming at the SPS PDSCH needs to be added to the first HARQ-ACK codebook, and thus 3-bit HARQ-ACK is obtained.

A base station side: in the same way, the UE side understands that the base station side can also determine to receive the HARQ-ACK according to the 3-bit HARQ-ACK in slot n + 4.

For the subsequent radio frame i +1, both the terminal and the base station are considered to transmit according to the updated SPS, i.e. there is SPS transmission in slot n.

As can be seen from the first and second cases in the method 2, no matter whether the UE receives the PDCCH indicating the SPS update, the UE is not changed to be in the SPS activation state and the slot n +4 contains the SPS HARQ-ACK to be fed back because the SPS HARQ-ACK feedback positions before and after the update are consistent, and in the slot n +4, the HARQ-ACK aiming at the SPS PDSCH is always required to be added to the first HARQ-ACK codebook, so that the understanding of the terminal and the base station on the feedback bit number is consistent.

It should be noted that, the above embodiment only uses slot-based scheduling and transmission as an example to explain how to transmit the feedback information of HARQ-ACK at the same time domain position, and makes the terminal and the network side understand the feedback information of HARQ-ACK consistently, but the embodiment is not limited to the above embodiment, and may also use other manners as an example, for example, when performing scheduling and transmission based on mini-slot, the above method may also be used. The same parts are not described herein again. In addition, in the above embodiment, only the addition of SPS HARQ-ACK to the first HARQ-ACK codebook is taken as an example for illustration, and the same applies when SPS HARQ-ACK needs to be reduced for the first HARQ-ACK codebook in a specific embodiment. In the above embodiment, taking the PDCCH as an example including both the HARQ-ACK indicator field and the time domain indicator field, if only one indication field is contained, and the content corresponding to the other indication field can be regarded as a fixed value, the above method is also applicable, if the PDCCH indicating SPS update and activation does not include the HARQ-ACK timing indication field but includes the time domain indication field, the same pre-configured or agreed HARQ-ACK timing is used, i.e. the HARQ-ACK timing corresponding to the PDCCH indicating SPS update and activation is itself the same, only the same time domain position of the PDSCH determined according to the scheduling timing indicated by the time domain indication field in the PDCCH is required to be ensured (at this time, the same PDCCH transmission position with the same scheduling timing, or different PDCCH transmission positions and different scheduling timings are required, but the scheduling result is the PDSCH in the same slot), so that the SPS transmission opportunities can be ensured to be the same, and the same feedback position is ensured; if the PDCCH for indicating the SPS updating and activating comprises the HARQ-ACK timing indication domain but not the time domain indication domain, using the same pre-configured scheduling timing, namely the scheduling timing corresponding to the SPS updating and activating PDCCH is indicated to be the same, if the SPS updating and activating PDCCH is indicated to be sent at the same time, determining the same PDSCH transmission time, namely ensuring the SPS transmission opportunities to be the same, at the moment, ensuring the same HARQ-ACK timing to be indicated, namely ensuring the same feedback position, if the SPS updating and activating PDCCH is indicated to be sent at different times, determining different PDSCH transmission times, at the moment, indicating different HARQ-ACK timing to achieve the purpose of ensuring the same feedback position; if the PDCCH indicating SPS update and activation does not include the HARQ-ACK timing indication domain and the time domain indication domain, the same HARQ-ACK timing and the same scheduling timing are used, and only the PDCCH indicating SPS update and activation needs to be guaranteed to be sent at the same time, the same PDSCH transmission time can be determined, and the SPS transmission opportunities can be guaranteed to be the same, so that the same feedback positions are guaranteed, which is not illustrated here.

In summary, on the terminal side, referring to fig. 7, an embodiment of the present invention provides a method for transmitting a harq response, where the method includes:

s601, receiving a PDCCH scrambled by using a first RNTI, wherein the time domain position of HARQ-ACK of the SPS PDSCH determined by the PDCCH scrambled by using the first RNTI is the same as the time domain position of HARQ-ACK of the SPS PDSCH determined by the PDCCH indicating activation of the SPS PDSCH;

s602, according to the PDCCH scrambled by the first RNTI, the HARQ-ACK of the SPS PDSCH is sent.

According to the transmission method of the hybrid automatic repeat request response, firstly, a terminal receives a PDCCH scrambled by using a first RNTI, and the time domain position of HARQ-ACK of an SPS PDSCH determined according to the PDCCH scrambled by using the first RNTI is the same as the time domain position of HARQ-ACK of the SPS PDSCH determined according to the PDCCH indicating activation of the SPS PDSCH; the terminal then transmits HARQ-ACK of the SPS PDSCH according to the PDCCH scrambled using the first RNTI. Therefore, in the application, the terminal receives the PDCCH scrambled by the first RNTI, so that the feedback time domain position of the HARQ-ACK corresponding to the SPS PDSCH determined according to the PDCCH scrambled by the first RNTI is kept unchanged, the terminal and the network side can be ensured to understand the feedback content of the HARQ-ACK consistently, and the transmission of the HARQ-ACK corresponding to the SPS PDSCH is realized in a 5G network architecture.

Optionally, the determining, in S601, the time domain position of the HARQ-ACK of the SPS PDSCH according to the PDCCH scrambled with the first RNTI and the time domain position of the HARQ-ACK of the SPS PDSCH according to the PDCCH indicating activation of the SPS PDSCH are the same, including:

when the DCI format used by the PDCCH includes a feedback timing indication field for indicating the timing from the PDSCH to the HARQ-ACK, the feedback timing indication field in the DCI format used by the PDCCH scrambled by using the first RNTI is the same as the content indicated by the feedback timing indication field in the DCI format used by the PDCCH for indicating the SPS PDSCH activation. For example, the method 1 of the above embodiments provides an example.

By the method, the embodiment of the application provides various modes for determining the time domain position of the HARQ-ACK of the SPS PDSCH by using the PDCCH scrambled by the first radio RNTI, and the mode for ensuring the time domain position of the HARQ-ACK of the SPS PDSCH to be unchanged is further improved to be more flexible.

Optionally, the determining, according to the PDCCH scrambled with the first RNTI, the time domain position of the HARQ-ACK of the SPS PDSCH is the same as the determining, according to the PDCCH indicating activation of the SPS PDSCH, of the HARQ-ACK of the SPS PDSCH, including:

when the DCI format used by the PDCCH comprises a time domain indication domain and a feedback timing indication domain for indicating the PDSCH-to-HARQ-ACK timing, the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the feedback timing indication domain in the DCI format used by the PDCCH scrambled by using the first RNTI and the scheduling timing indicated by the time domain indication domain is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined according to the feedback timing indication domain in the DCI format used by the PDCCH for indicating the activation of the SPS PDSCH and the scheduling timing indicated by the time domain indication domain. For example, the scheme provided in the above embodiment mode 1 or mode 2 may be adopted to determine that the HARQ-ACK feedback time domain positions before and after the SPS update are the same.

Optionally, the SPS PDSCH includes a PDSCH not corresponding to a PDCCH, or an SPS PDSCH transmitted in a subsequent SPS transmission opportunity determined from a PDCCH indicating SPS activation, or an SPS PDSCH transmitted in a subsequent SPS transmission opportunity determined from a PDCCH indicating SPS update/reset.

Optionally, new data in the PDCCH scrambled with the first RNTI indicates NDI field indication 0.

On the terminal side, referring to fig. 8, a method for transmitting a hybrid automatic repeat request response according to an embodiment of the present invention includes:

s701, transmitting the PDCCH scrambled by using the first RNTI, wherein the time domain position of the HARQ-ACK of the SPS PDSCH determined by the PDCCH scrambled by using the first RNTI is the same as the time domain position of the HARQ-ACK of the SPS PDSCH determined by the PDCCH indicating activation of the SPS PDSCH;

s702, receiving HARQ-ACK of SPS PDSCH according to PDCCH scrambled by using first RNTI.
