Description

HARQ-ACK transmission method, terminal equipment and network equipment

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on September 21, 2018, with application number 201811110560.7, and the invention name is "A HARQ-ACK transmission method, terminal device, and network device." Incorporated by reference in this application.

Technical field

The present application relates to the field of communication technologies, and in particular, to a HARQ-ACK transmission method, a terminal device, and a network device.

Background technique

In the fifth generation mobile communication technology (5Generation, 5G) network, the wireless air interface technology (NR) supports the repeated transmission of the Physical Uplink Shared Channel (PUSCH), and also supports the physical uplink control channel (Physical Uplink). When the time domain resources of the Control Channel (PUCCH) and the PUSCH overlap, the uplink control information (Uplink Control Information) (UCI) carried on the PUCCH is transferred to the PUSCH for transmission, thereby preventing multiple channels from being transmitted in parallel.

For multiple PUSCH transmissions scheduled by an Uplink (UL) grant, this UL grant can only be used for Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) transmission on the first PUSCH It is determined that, for subsequent PUSCHs, it is currently not supported to transmit HARQ-ACKs for downlink transmissions that occur after the UL grant on these PUSCHs, which will cause excessive downlink transmission delays, thereby affecting system throughput.

For PUSCHs that do not have a physical downlink control channel (Physical Downlink Control Channel, PDCCH), there is currently no mechanism to define which downlink transmissions can be HARQ-ACK feedback on the PUSCH. According to the existing mechanism, as long as it is determined according to the HARQ-ACK feedback timing that feedback needs to be performed on the PUSCH time slot, if the PUCCH carrying the HARQ-ACK and the PUSCH overlap, the HARQ-ACK will be transmitted on the PUSCH. The occurrence time is later than the time when the PUSCH starts to prepare, and the PUSCH cannot obtain the final number of HARQ-ACK bits when preparing. As a result, the data and the final HARQ-ACK cannot be correctly rate-matched.

detailed description

In order to make the purpose, technical solution, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

The following describes the background technology of the embodiments of the present application.

In a Long Term Evolution (LTE) wireless communication system, when terminal equipment, such as user equipment (UE), has both PUSCH and UCI transmission in a certain subframe, the time domain of the PUCCH and PUSCH carrying the UCI There may be overlapping resources. If the UE supports simultaneous transmission of PUCCH and PUSCH and the high-level signaling configuration can perform simultaneous transmission of PUCCH and PUSCH, then PUCCH and PUSCH can be transmitted at the same time, such as transmitting UCI on PUCCH and transmitting data on PUSCH. If the UE does not support the simultaneous transmission of PUCCH and PUSCH or the high-level signaling configuration cannot perform simultaneous transmission of PUCCH and PUSCH, the UCI carried on the PUCCH will be transferred to the PUSCH and the information originally carried on the PUSCH will be multiplexed and transmitted on the PUSCH. The UCI includes at least Hybrid Automatic Repeat Request (ARQ-ACK), Channel State Information (CSI), and Scheduling Request (SR).

In particular, for a PUSCH that does not use repeated transmission, when the PUSCH has a corresponding PDCCH (that is, scheduled by UL grant) and the PDCCH uses Downlink Control Information (DCI) format 0_1, the DCI format 0_1 contains 1 bit or 2 The Bit Downlink Assignment Index (DAI), commonly referred to as UL DAI, is used to indicate the transmission of HARQ-ACK on the PUSCH. This is because if there is no DAI indication in the DCI format 0_1, when the UE does not receive any downlink transmission that requires HARQ-ACK feedback at the time domain location where the PUSCH is located, the UE will determine that there is no HARQ-ACK transmission on the PUSCH; when When the UE receives downlink transmission that requires HARQ-ACK feedback at the time domain location where the PUSCH is located, the UE determines that there is a HARQ-ACK transmission determined on the PUSCH according to the configured codebook.

When HARQ-ACK is configured to use Semi-Static Codebook for transmission, 1-bit DAI is included in DCI format 0_1 to indicate whether HARQ-ACK transmission exists on PUSCH, that is, to avoid packet loss due to downlink transmission As a result, the terminal device and the network device have different understandings on whether there is HARQ-ACK transmission on the PUSCH. When HARQ-ACK is configured to use a dynamic codebook (Dynamic Codebook) for transmission, DCI format 0_1 contains 2 or 4 bits of DAI, which is used to indicate the total number of bits of HARQ-ACK transmission on the PUSCH. If a subcodebook ( For downlink transmission based on Transport Block (TB) and downlink codebook based on Coding Block Group (CBG), each sub-codebook corresponds to a 2-bit DAI for a total of 4-bit DAI. For the dynamic codebook, the DCI used by the PDCCH in the PDCCH monitoring opportunity (Monitoring Occasion) set corresponding to the dynamic codebook (used to schedule PDSCH or PDCCH indicating the release of downlink-Persistent Scheduling (SPS) resources) For example, DCI format 1_0 or 1_1) also contains DAI, which is usually called DL DAI. When single carrier is used, it only contains 2 bit DAI, and when it is multi carrier, it includes 4 bit DAI. It is divided into 2 bit C-DAI and 2 bit T-DAI. Used to indicate the order and size of the codebook.

At present, the 5G NR system supports the repeated transmission of the PUSCH, and also supports the transfer of UCI carried on the PUCCH to the PUSCH for transmission when the time domain resources of the PUCCH and the PUSCH overlap, thereby avoiding the simultaneous transmission of multiple channels.

Considering that when transmitting HARQ-ACK on PUSCH, when HARQ-ACK adopts rate matching and data multiplexing transmission, the uplink data (ie, UL-SCH) carried on PUSCH needs to be prepared before the rate matching, for example, before rate matching. The number of HARQ-ACK bits transmitted on the PUSCH, so as to determine the resources occupied by the HARQ-ACK on the PUSCH, and then determine the resources used for data transmission, and then perform rate matching on the data. Therefore, it is defined that downlink transmissions that occur after UL grant cannot perform HARQ-ACK feedback on the PUSCH scheduled by the UL grant. These downlink transmissions refer to the indicated semi-persistent scheduling detected in PDCCH detection opportunity monitoring after UL grant. Semi-Persistent Scheduling (SPS) resource release or PDSCH scheduled by the PDCCH detected in the PDCCH monitoring after UL grant. The purpose is to ensure that when the UL grant is received, the PUSCH scheduled by the UL grant can be determined. The number of HARQ-ACK bits transmitted on the network to ensure timely data preparation. In addition, when the DAI is included in the UL grant, the DAI may indicate a value for determining the number of HARQ-ACK bits transmitted on the PUSCH. For example, the value of the DAI indicates that HARQ needs to be performed in the time slot of the PUSCH scheduled by the UL grant. -The total number of downlink transmissions of the ACK transmission. Because the network device cannot predict the number of downlink transmissions that occur after the UL grant, the DAI in the UL grant cannot include the downlink transmissions that occur after the UL grant. Preferably, the network device should not schedule the downlink transmission after the UL grant to perform HARQ-ACK feedback in the time slot scheduled by the UL grant. For example, you can set a larger HARQ-ACK feedback timing (instruct PDSCH or SPS to release the PDCCH). The interval from the time slot to the time slot where the HARQ-ACK transmission is located) K0 value to avoid the HARQ-ACK feedback of these downlink transmissions that occur after the UL grant falls in the time slot scheduled by the UL grant. Since this definition is for a single PUSCH transmission, the maximum transmission delay may be a time slot.

In addition, for a case where multiple PUSCH transmissions are scheduled by one PDCCH at the same time, for example, the PDCCH in slot n simultaneously schedules N PUSCH transmissions in N slots starting from slot n + K2, or given N K2 values, Scheduling N PUSCH transmissions in N time slots determined based on N K2 values. The PUSCH scheduling information in each time slot can be the same or different. The PUSCH in each time slot carries independent transport blocks (Transport Block , TB) instead of one TB of repeated transmission, that is, one PDCCH carries scheduling information for scheduling multiple PUSCH transmissions in multiple time slots simultaneously. In this case, there is also the transmission problem of the HARQ-ACK on the PUSCH when the similar PUSCH is repeatedly transmitted.

In addition, for PUSCH transmissions in the 5G NR system that do not have corresponding PDCCHs, such as SPS PUSCH, grant-free PUSCH, and PUSCH carrying SP-CSI, etc., because there is no corresponding UL grant, the relative position of downlink transmission and UL grant cannot be determined. Determine which downlink HARQ-ACKs cannot be transmitted on this PUSCH. If any HARQ-ACK that is determined according to the HARQ-ACK feedback timing and needs to be used for downlink transmission of HARQ-ACK in the time slot where these PUSCH transmissions are located is transmitted on these PUSCH, there may be these downlink transmissions at a distance from this The near time domain location of the PUSCH occurs, resulting in that the terminal has not yet obtained the final HARQ-ACK codebook size when it needs to start preparing uplink data on the PUSCH. This is because, for a dynamic codebook, only the UE receives the corresponding The number of HARQ-ACK bits transmitted in this time slot can only be determined during the last downlink transmission of HARQ-ACK feedback.

Therefore, in 5G NR, for multiple PUSCH transmissions scheduled by one UL grant, the UL grant can only be used to determine the HARQ-ACK transmission on the first PUSCH. For subsequent PUSCH, if the existing mechanism is still used, no HARQ-ACK supporting the transmission of downlink transmissions that occur after the UL grant on these PUSCHs will cause excessive downlink transmission delays, which may be delays of multiple time slots, thereby affecting system throughput. For example, when HARQ-ACK is transmitted on the PUSCH, considering the processing delay of the PUSCH, the PDSCH scheduled by the PDCCH after the PDCCH scheduling the PUSCH or the PDCCH indicating the release of downlink SPS resources (also known as SPS PDSCH release), which HARQ-ACK cannot be transmitted on this PUSCH. For multiple PUSCHs scheduled by the same PDCCH, if the PDCCH scheduling the multiple PUSCHs is used as a demarcation point, it is determined that the downlink transmission set of HARQ-ACK can be transmitted on each PUSCH, which will result in a longer period of downlink. Transmission could not get HARQ-ACK feedback in time. As shown in Figure 1, for PUSCH in time slots n + 1, n + 2, and n + 3, if the PDCCH in time slot n-1 is used as a reference, None of the downlink transmissions scheduled by the PDCCH can perform HARQ-ACK feedback on these PUSCHs, thereby affecting downlink throughput.

For a PUSCH without a corresponding PDCCH, there is currently no mechanism to define which downlink transmissions can be HARQ-ACK feedback on the PUSCH. According to the existing mechanism, as long as it is determined according to the HARQ-ACK feedback timing that feedback needs to be performed in the time slot where the PUSCH is located, if the bearer The PUCCH of the HARQ-ACK and the PUSCH overlap, and the HARQ-ACK will be transmitted on the PUSCH. A potential problem with this scheme is that a certain downlink transmission occurs later (later than the time when the PUSCH starts to prepare), and the PUSCH cannot be prepared during the preparation. Obtain the final number of HARQ-ACK bits, so that the data and the final HARQ-ACK cannot be correctly rate-matched.

In view of this, the embodiment of the present application provides a new mechanism. In the embodiment of the present application, when the PUCCH carrying the HARQ-ACK and the PUSCH of the first type overlap, the HARQ of the downlink transmission corresponding to the PDCCH of the first type is determined. -ACK is not transmitted on the first type of PUSCH. That is, when HARQ-ACK is transmitted on the first type of PUSCH, a reference time is determined according to a predetermined processing delay. PDSCH scheduled by the PDCCH after the reference time cannot transmit HARQ-ACK on the first type of PUSCH, thereby determining Which PDSCH can perform HARQ-ACK in each time slot, thereby avoiding the delay of transmitting the HARQ-ACK feedback of PDSCH to another time slot, which greatly compresses the feedback delay of downlink transmission, improves system transmission efficiency, and makes data and final HARQ-ACK enables correct rate matching.

The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings of the description.

Referring to FIG. 2, an embodiment of the present application provides a HARQ-ACK transmission method, and a flow of the method is described as follows. Since the HARQ-ACK transmission method involves the interaction process between the network device and the terminal device, in the following flow description, the processes performed by the network device and the terminal device will be described together.

S201. If there is an overlap between the PUCCH carrying the HARQ-ACK and the PUSCH of the first type, determine that HARQ-ACK for downlink transmission corresponding to the PDCCH of the first type is not transmitted on the PUSCH of the first type.

In the embodiment of the present application, the first type of PUSCH may include at least one of the following three types of PUSCH:

First, there is no PUSCH corresponding to PDCCH scheduling;

A second type of PUSCH other than the first PUSCH among at least two independent PUSCHs scheduled by the same PDCCH;

Third, PUSCHs other than the first PUSCH among PUSCHs that are repeatedly transmitted.

The downlink transmission corresponding to the first type of PDCCH may include: a PDSCH scheduled by the first type of PDCCH, and an SPS PDSCH released by the first type of PDCCH, and a PDCCH indicating the release of downlink SPS resources and The PDCCH is at least one of three types of downlink transmissions of the first type of PDCCH. The SPS PDSCH release is equivalent to the PDCCH indicating the release of the downlink SPS resources. Therefore, it means the PDCCH indicating the release of the downlink SPS resources and the PDCCH is the first type of PDCCH, and the HARQ-ACK corresponding to the SPS PDSCH release indicates. HARQ-ACK of the first type of PDCCH released by the SPS PDSCH.

If the PUCCH carrying the HARQ-ACK overlaps with the first type of PUSCH, the HARQ-ACK carried on the PUCCH may be transferred to the PUSCH for transmission. In this embodiment of the present application, it is determined that HARQ-ACKs for downlink transmission corresponding to the first type of PDCCH are not transmitted on the first type of PUSCH. This embodiment of the present application determines that the HARQ-ACK for downlink transmission corresponding to the first type of PDCCH is not transmitted on the first type of PUSCH, which can be implemented in the following ways:

Method 1: Generate a non-acknowledgement (Negative Acknowledgement, NACK) at a position corresponding to the downlink transmission corresponding to the first type of PDCCH in the HARQ-ACK codebook transmitted on the PUSCH.

Manner 2: Remove the HARQ-ACK corresponding to the downlink transmission corresponding to the first type of PDCCH from the HARQ-ACK codebook transmitted on the PUSCH.

Method 3: When the HARQ-ACK codebook transmitted on the PUSCH is generated, the HARQ-ACK for downlink transmission corresponding to the first type of PDCCH is not included.

In the embodiment of the present application, before determining that the HARQ-ACK for downlink transmission corresponding to the first type of PDCCH is not transmitted on the first type of PUSCH, it may also be determined that the terminal device does not support or is not configured for simultaneous transmission of PUCCH and PUSCH. Alternatively, the embodiment of the present application may also determine that the PUCCH and the first type of PUSCH meet the time condition for transferring the HARQ-ACK carried on the PUCCH to the PUSCH for transmission. That is, when the HARQ-ACK is transmitted on the first type of PUSCH in the embodiment of the present application, a reference time may be determined first, and the PDSCH scheduled by the PDCCH after the reference time cannot transmit the HARQ-ACK on the first type of PUSCH. Among them, the PUCCH and the first type of PUSCH meet the time condition for transferring the HARQ-ACK carried on the PUCCH to the PUSCH for transmission, that is, the first symbol of the earliest channel in the PUCCH and PUSCH with the first symbol meeting the following conditions, including The following conditions:

Condition one, no earlier than the first uplink symbol at T1 time after the last symbol of HARQ-ACK feedback on the PUCCH, or no later than the last of any PDSCH that requires HARQ-ACK feedback on the PUCCH The first upstream symbol at T1 time after one symbol.

Condition two, no earlier than the first uplink symbol of T2 time after the last symbol in the PDSCH or SPS PDSCH release corresponding to the HARQ-ACK feedback on the PUCCH, or no earlier than the PUCCH The first uplink symbol at T2 time after the last symbol of any PDCCH in the PDSCH or SPS PDSCH feedback corresponding to HARQ-ACK feedback.

Among them, T1 and T2 can be determined according to parameters such as UE capability and transmission configuration. When the starting symbols of PUCCH and PUSCH are aligned, the channel with the longest transmission length is selected for the above judgment. When both the starting symbol and the transmission length are consistent, the terminal device autonomously selects a time condition.

In the embodiment of the present application, the first type of PDCCH may be a PDCCH transmitted after the first time domain position. Among them, the first time domain position may be:

(1) The position of the virtual PDCCH corresponding to the PUSCH.

(2) T-th symbol before the first symbol of the PUSCH, where T is a predetermined delay.

(3) A predetermined downlink symbol or Flexible symbol or a PDCCH detection opportunity that meets a preset condition. The preset condition may be any one of the following preset conditions:

(31) Prior to the first symbol of the PUSCH and not less than T symbols apart from the first symbol, where T is a predetermined delay.

(32) In the Kth slot before the slot where the PUSCH is located, where K is a scheduling timing value corresponding to the first PUSCH. That is, K2 notified in the PDCCH scheduling the first PUSCH, or a K2 value pre-configured by high-level signaling. K2 represents the time slot interval between the PDCCH scheduling PUSCH and PUSCH, that is, the PDCCH scheduling slot n + K2 transmitted in time slot n. PUSCH transmission in.

(33) Prior to the time slot in which the PUSCH is located, and in a time slot that is not less than K slots in the time slot where the PUSCH is located, where K is a scheduling timing value corresponding to the first PUSCH.

Further, the predetermined downlink symbol is the latest downlink symbol that satisfies the preset condition, or the predetermined downlink symbol is the first downlink symbol in a time slot that satisfies the preset condition. The Flexible symbol is the latest Flexible symbol that meets the preset condition, or the Flexible symbol is the first Flexible symbol in the time slot that meets the preset condition. The PDCCH detection opportunity is the latest PDCCH detection opportunity that satisfies a preset condition, or the PDCCH detection opportunity is the first PDCCH detection opportunity in a time slot that satisfies the preset condition.

The virtual PDCCH position can be:

(11) The Tth symbol before the first symbol of the PUSCH, where T is a predetermined delay.

(12) A predetermined downlink symbol or Flexible symbol or a PDCCH detection opportunity that meets a preset condition. The preset condition may be any one of the following preset conditions:

(121) Prior to the first symbol of the PUSCH and not less than T symbols apart from the first symbol, where T is a predetermined delay.

(122) In the Kth slot before the slot where the PUSCH is located, where K is a scheduling timing value corresponding to the first PUSCH. That is, K2 notified in the PDCCH scheduling the first PUSCH, or a K2 value pre-configured by high-level signaling. K2 represents the time slot interval between the PDCCH scheduling PUSCH and PUSCH, that is, the PDCCH scheduling slot n + K2 transmitted in time slot n. PUSCH transmission in.

(123) Prior to the time slot where the PUSCH is located, and in a time slot whose interval with the PUSCH is not less than K time slots, where K is a scheduling timing value corresponding to the first PUSCH.

In the embodiment of the present application, the above definition of T may be one of the following definitions:

Among them, μ is the number of the smallest subcarrier interval among PDCCH, PUCCH, and PUSCH. Of course, if there are multiple PUCCH and / or multiple PUSCH, here is the smallest subcarrier interval among multiple channels; Determine the smallest subcarrier interval in multiple PUCCHs and / or multiple PUSCHs, and then compare it with the subcarrier interval of the PDCCH, and choose the smallest one. Z is the required delay of A-CSI; d is the number of symbols overlapped between the PDCCH and the scheduled PDSCH; if the first symbol of the PUSCH contains only the demodulation reference signal DMRS, then d2,1 = 0, otherwise d2 , 1 = 1; if a PDCCH scheduling PUSCH bandwidth part BWP trigger switch is switched to a predetermined d2,2 BWP time required otherwise d2,2 = 0; T _c is the elementary time unit in NR (e.g. sampling time Interval), κ is the ratio between the basic time unit of Long Term Evolution LTE and the basic time unit of NR.

If the PUSCH of the first type is a PUSCH corresponding to the PDCCH scheduling, T is a scheduling timing value indicated in the PDCCH that activates the PUSCH transmission of the first type;

If the PUSCH of the first type is a PUSCH other than the first PUSCH among the PUSCHs that are repeatedly transmitted repeatedly, T is the scheduling timing value indicated in the PDCCH that schedules the PUSCH transmission of the repeated transmissions.

In order to facilitate understanding, the following describes the technical solutions provided by the embodiments of the present application with specific embodiments.

Embodiment 1. Please refer to FIG. 3, which is a schematic diagram of scheduling and feedback in Embodiment 1. Figure 3 uses a Frequency Division Duplex (FDD) system as an example. There are uplink resources and downlink resources in each time slot. Depending on the pre-configuration of high-level signaling, there may be different numbers of PDSCH scheduled transmissions in different time slots, and there may be different numbers of PDCCH monitoring. Or, there may be the same number of PDSCH scheduled transmissions in different time slots, and there may be the same number of PDCCH monitoring. The network device sends a UL grant in the second monitoring occasion in time slot n-3, that is, a PDCCH using DCI format 0_0 or 0_1, which is used to schedule the terminal in four consecutive time slots beginning with time slot n. Repeated PUSCH transmission. Among them, K2 represents the uplink scheduling timing, which is used to express that the interval between the time slot for transmitting UL grant and the time slot where the scheduled PUSCH is located is K2, that is, the PUSCH is transmitted in the K2th time slot after the time slot for transmitting UL grant. When the HARQ_ACK needs to be transmitted on the PUSCH, for example, the HARQ-ACK needs to be transmitted over the PUCCH in the time slot where the PUSCH transmission is needed, and the PUCCH carrying the HARQ-ACK and the PUSCH time domain resources overlap, and the PUCCH and PUSCH meet the reservation When the UCI multiplexing time condition is not supported or configured for simultaneous transmission of PUCCH and PUSCH, it is determined that HARQ-ACK for downlink transmission corresponding to the first type of PDCCH is not transmitted on the first type of PUSCH, and is determined as follows:

For the PUSCH in time slot n, it is obvious that the PDSCH in time slot n-3 and the PDSCH in time slot before time slot n-3 are both no later than the UL grant corresponding to the PUSCH in time slot n. For example, The DL grant scheduling of the second PDCCH monitoring transmission in slot n-3, for example, uses a PDCCH of DCI format 1_0 or 1_1 for scheduling a PDCCH released by PDSCH or SPS PDSCH. Therefore, HARQ-ACK feedback can be performed on the PUSCH in time slot n. Whether or not HARQ-ACK feedback is actually performed depends on the feedback timing K1 of these PDSCHs. Among them, K1 indicates that HARQ-ACK is transmitted in K1 slots after the PDSCH slot. When K1 corresponding to these PDSCHs indicates that HARQ-ACK feedback is performed in slot n, for example, PDSCH corresponding to PDSCH in slot n-5 K1 = 5, if the PUCCH resources carrying these HARQ-ACKs overlap with the PUSCH resources in slot n, and simultaneous transmission of PUCCH and PUSCH is not supported, the actual HARQ-ACK corresponding to these PDSCHs can be fed back in slot n Transmission on PUSCH. The PDSCH in the time slot after the time slot n-3 is due to the position of the UL grant corresponding to the PUSCH in the time slot n, for example, the DL of the second PDCCH monitoring in the time slot n-3 The grant is scheduled, therefore, HARQ-ACK transmission cannot be performed on the PUSCH in slot n.

For the PUSCH in time slot n + 1, if it is also determined which PDSCH can perform HARQ-ACK transmission on this PUSCH based on the UL grant position in time slot n-3, the UL grant and The interval between PUSCHs in slot n + 1 far exceeds the scheduling timing and processing delay of the PUSCH, which will cause some downlink transmissions to increase feedback delays, which is not conducive to downlink transmission efficiency. For example, if the UL grant position in time slot n-3 is used, the PDSCH in the time slot after time slot n-3 cannot perform HARQ-ACK transmission on the PUSCH in time slot n + 1. But in fact, PDSCH in some time slots can satisfy the transmission of HARQ-ACK on PUSCH in time slot n + 1. For example, PDSCH in time slot n-2, assuming UL in time slot n-3 The time interval between grant and the first PUSCH is used as the PUSCH preparation time. It only needs to start the PUSCH preparation in the time slot n + 1 at the end of the second PDCCH monitoring in the time slot n-2. Generally, the actual preparation time may be smaller than the time interval between the UL grant in the time slot n-3 and the first PUSCH. For a PDSCH scheduled by a PDCCH no later than this time, the terminal device can always At this moment, the number of PDSCHs that have been scheduled and need to be HARQ-ACK feedback in slot n + 1 is known. Even though the PDSCH reception and analysis may not be completed, as long as the PDCCH scheduling PDSCH is received, the number of HARQ-ACK bits can be known, and how many bits of HARQ-ACK transmission exist in the time slot n + 1, thereby ensuring the network When the device sends a UL grant, it can set the correct number of HARQ-ACK bits (if there is a UL DAI field), and it can also ensure that the UE and the network device can estimate the resources occupied by the uplink data on the PUSCH according to the number of HARQ-ACK bits. Uplink data, such as coding and rate matching. Therefore, all PDSCHs scheduled by the PDCCH monitoring no later than the second PDCCH in time slot n-2 can perform HARQ-ACK transmission on the PUSCH in time slot n + 1. For example, both PDSCHs in time slot n-2 can perform HARQ-ACK transmission on the PUSCH in time slot n + 1. Of course, PDSCHs that can perform HARQ-ACK transmission on the PUSCH in time slot n can certainly be performed on HARQ-ACK transmission is performed on PUSCH in slot n + 1. Specifically, it can be implemented in the following ways.

Method 1. The terminal device may determine a time domain position based on a predetermined processing delay T, and use this time domain position to define which PDSCHs can transmit HARQ-ACK on the PUSCH in the time slot n + 1.

The predetermined processing delay may be a symbol-level length or a time length. For example, the processing delay when the PUSCH carries UCI, such as N2 + Y symbols, where N2 is the PUSCH related to the subcarrier interval and the terminal equipment capability. Processing delay. Y is the predetermined additional processing delay to carry UCI, and T can also be the length of time, which may have several definitions:

In the above (1)-(4), μ is the number of the smallest subcarrier interval among the PDCCH, PUCCH, and PUSCH; if the first symbol of the PUSCH contains only DMRS, d _2,1 = 0, otherwise d _{2, 1} = 1; if the PDCCH scheduling PUSCH triggers a bandwidth BWP handover, then d _2,2 is the time required for the scheduled BWP handover, otherwise d _2,2 = 0; T _c is the basic time unit in NR, that is, The sampling time interval may be a predetermined value; κ is a ratio between a basic time unit of LTE and a basic time unit of NR, or may be a predetermined fixed value. For (2), Z is the required delay of A-CSI, and d is the number of symbols overlapping between the PDCCH and the scheduled PDSCH.

For example, as shown in FIG. 3, based on the first symbol of the PUSCH in the time slot n + 1, determine the Tth symbol before the first symbol or the first interval not less than T symbols from the first symbol. Each PDCCH monitoring is a reference time. For example, if it is determined that the second PDCCH monitoring in slot n-2 is the reference time (specifically its ending position), then it can be determined that the PDSCH in slot n-2 and the slot before slot n-2 are both HARQ-ACK feedback can be performed on the PUSCH in time slot n + 1, and PDSCH in the time slot after time slot n-2 cannot perform HARQ-ACK feedback on the PUSCH in time slot n + 1. Of course, it is also possible to define the first symbol as the first downward symbol or flexible symbol.

In the embodiment of the present application, the predetermined processing delay may also be a slot level, for example, it is equivalent to a K2 value indicated in a UL grant that triggers repeated transmission of PUSCH. In this first embodiment, when K = 3, the nearest PDCCH monitoring in the third time slot before time slot n + 1 can be determined, that is, the second PDCCH monitoring in time slot n-2 is the reference time (specifically Its end position). Definitely define a specific symbol in the third slot before the slot n + 1, such as the first symbol, or the last symbol, or the first DL or flexible symbol, or the last DL or flexible symbol, etc. That is, the second specific coincidence in the time slot n-2 is also a reference time (specifically, its ending position). Therefore, it can be determined that the PDSCH in the time slot n-2 and the time slot before the time slot n-2 can both perform HARQ-ACK feedback on the PUSCH in the time slot n + 1, and the time slot after the time slot n-2 The PDSCH in the middle cannot perform HARQ-ACK feedback on the PUSCH in the slot n + 1.

Method 2: A virtual UL grant corresponding to the PUSCH in the time slot n + 1 is defined. Specifically, a nearest PDCCH monitoring can be determined according to the above T or K value. Assume that there is a virtual UL grant for scheduling PUSCH in time slot n + 1. After the virtual grant is defined, the PUSCH in time slot n is processed to determine that no later than the PDCCH monitoring where the virtual grant is located. The PDSCH scheduled by the PDCCH can perform HARQ-ACK feedback on slot n + 1. For example, for PDSCH in timeslot n-2 and timeslots before timeslot n-2, it is determined that the PDSCH scheduled by the PDCCH transmitted after the PDCCH monitoring and occasion of the virtual grant cannot be HARQ-ACK on timeslot n + 1 Feedback, such as PDSCH in time slots after time slot n-2.

It can be seen that, according to the foregoing manner 1 and manner 2, as compared to the UL grant in slot n-3, which PDSCHs can be HARQ-ACK, and the PUSCH in slot n + 1 can support the PDSCH in slot n-2. The PDSCH performs HARQ-ACK feedback, thereby avoiding delaying the HARQ-ACK feedback of the PDSCH in the slot n-2 to be transmitted after the slot n + 3, which greatly compresses the feedback delay of downlink transmission and improves system transmission efficiency.

For the PUSCH in the time slot n + 2, a method similar to the PUSCH in the time slot n + 1 can also be used to determine a reference time. If it is determined that the Tth symbol before the first symbol is the reference time, it is a time slot. A symbol in PDSCH in n-1. It can also be determined that the PDSCH in slot n-1 is scheduled by the DL grant that was transmitted before this time, so it is possible to transmit HARQ-ACK on the PUSCH in slot n + 2, that is, any symbol that meets T time Can be used as a reference moment. If it is determined that the first PDCCH that is not less than T symbols apart from the first symbol is monitored (of course, it is also possible to define the first DL or flexible symbol) as the reference time or virtual UL location, because it is determined according to T There is no PDCCH monitoring occasion at the time, and then the search for the first PDCCH monitoring occasion in the time slot n-1 is further advanced as a reference time. The rest of the processing is similar to that in time slot n + 1, and is not repeated here.

For the PUSCH in the time slot n + 3, a method in which the PUSCH in the time slot n + 2 is consistent may be adopted, and details are not described herein again.

In the above process, it is assumed that the HARQ-ACK feedback timing set K1 = {2,3,4,5}, K1 is a time slot unit, and is used to determine a PUCCH carrying the HARQ-ACK of the PDSCH according to the time slot where a PDSCH is transmitted. The time slot in which the transmission occurred. When the semi-static HARQ-ACK codebook is configured to be used, the position of the semi-static HARQ-ACK codebook in a time slot corresponding to the PDSCH that cannot perform HARQ-ACK transmission on the PUSCH in the time slot is set to NACK. For example, taking slot n + 1 as an example, according to the definition of semi-static HARQ-ACK codebook, the PDSCH candidate set corresponding to semi-static HARQ-ACK codebook in slot n + 1 can be determined as slot n-4 The PDSCH transmissions in, n-3, n-2, and n-1 include a total of six PDSCH transmissions. However, according to the above method, it is determined that the PDSCH in the slot n-1 cannot perform HARQ-ACK feedback on the PUSCH in the slot n + 1, then the HARQ-ACK codebook transmitted on the PUSCH in the slot n + 1 will The HARQ-ACK position of the PDSCH in the corresponding time slot n-1 is set to NACK, and if the PDSCH in the time slot n-2 and the time slot before n-2 is based on its corresponding K1 value (indicated in its corresponding DL grant) ) It is determined that HARQ-ACK feedback needs to be performed in time slot n + 1, and then its HARQ-ACK is generated according to the PDSCH receiving situation. If the conditions for semi-static codebook rollback are not met (that is, when only one downlink transmission is received and the downlink transmission is scheduled by DCI format 1_0 and DAI = 1), it is mapped to the semi-static corresponding to time slot n + 1 The corresponding position in the HARQ-ACK codebook, and the HARQ-ACK codebook is transmitted on the PUSCH in the time slot n + 1. If the conditions of the semi-static codebook fallback are met, HARQ-ACK is generated for only one downlink transmission received and transmitted on the PUSCH in slot n + 1.

When the dynamic HARQ-ACK codebook is configured to be used, the HARQ-ACK of the PDSCH that cannot perform HARQ-ACK transmission on the PUSCH in the time slot is removed from the codebook. Also taking time slot n + 1 as an example, according to the definition of dynamic HARQ-ACK codebook, the PDCCH monitoring set corresponding to dynamic HARQ-ACK codebook in time slot n + 1 can be determined as time slots n-4, n-3 PDCCH monitoring in n-2, n-2, and n-1 (here for simplicity, it is assumed that the scheduling timings K0 in the candidate PDSCH set are all 0, and K0 represents the time slot interval between the PDCCH scheduling the PDSCH and the PDSCH, that is, Downlink uses intra-time slot scheduling. Of course, if K0 is not zero, the PDCCH monitoring set may be changed.), According to the DAI value carried in the PDCCH received in the PDCCH monitoring (that is, the DL grant in Figure 2). Determine the size of the dynamic HARQ-ACK codebook and the order of HARQ-ACK.

If the network device schedules the PDSCH in slot n-1 to perform HARQ-ACK feedback in slot n + 1 (that is, K1 = 2), then the dynamic codebook in slot n + 1 corresponds to its PDCCH monitoring The last PDCCH received by the set is the PDCCH in time slot n-1. According to the DAI in the PDCCH in time slot n-1, for example, it is determined that HARQ-ACK feedback needs to be performed on 6 PDSCHs. However, due to time slot n-1, The PDSCH in time slot cannot perform HARQ-ACK feedback on the PUSCH in time slot n + 1, and the HARQ-ACK corresponding to the PDSCH in time slot n-1 needs to be removed from the dynamic HARQ-ACK codebook. Of course, better, the network device should not give such a schedule, that is, the network device can prevent the terminal device from discarding the HARQ-ACK feedback of the PDSCH by setting a K1 value greater than 2 to the PDSCH in the time slot n-1. For example, if K1 = 3 is set, the PDSCH in time slot n-1 can perform HARQ-ACK feedback in time slot n + 2. At this time, the dynamic codebook in time slot n + 1 corresponds to its PDCCH monitoring set. The last PDCCH received is not the PDCCH in time slot n-1, but the PDCCH in time slot n-2. If the size of the codebook is determined according to the PDCCH in time slot n-2, there will be no A case where a PDSCH transmission discards HARQ_ACK.

In the embodiment of the present application, the network device determines whether there is HARQ-ACK on the PUSCH and how many bits of HARQ-ACK exist in each slot in the same manner as described above, and then performs HARQ-ACK reception on the PUSCH.

It should be noted that, in the first embodiment, only the value of the dynamic indication of the indication field in the PDCCH corresponding to the downlink transmission is taken as K1 as an example. In addition, K1 can also be pre-defined or pre-configured by high-level signaling. At this time, there is only one fixed feedback timing for each downlink transmission, but the change in this timing definition does not affect the implementation of the above scheme. In the first embodiment above, only FDD is used as an example. If it is time division duplex (TDD), the only difference is that the PDSCH candidate set determined by the semi-static codebook is not necessarily a continuous time slot. For dynamic The PDCCH monitoring set of the codebook may not be in consecutive time slots. These time slots may be excluded because there are no downlink transmission resources in some time slots or the downlink transmission resources are insufficient to support the candidate PDSCH time domain resource size.

It should be noted that, in the first embodiment, the HARQ-ACK transmission method provided in the embodiment of the present application is also applicable to a case where the same PDCCH jointly schedules N independent PUSCH transmissions. Replacing all or any of the above PDSCHs with SPS PDSCH release (ie, PDCCH indicating SPS resource release) is also applicable. It is also applicable to replace the above-mentioned one PDCCH scheduling one PUSCH repeated transmission with SPS PUSCH transmission or PUSCH transmission carrying SP-CSI. The difference is that each SPS PUSCH or SP-CSI PUSCH is not transmitted in continuous time slots. It is transmitted according to a pre-configured period in time-slots at periodic intervals. The UL grant scheduling PUSCH in the first embodiment can be replaced with a PDCCH that activates SPS PUSCH or SP-CSI PUSCH.

In summary, when the PUCCH carrying the HARQ-ACK overlaps with the PUSCH of the first type, it is determined that the HARQ-ACK of the downlink transmission corresponding to the PDCCH of the first type is not transmitted on the PUSCH of the first type. That is, when HARQ-ACK is transmitted on the first type PUSCH, a reference time is determined according to a predetermined processing delay. After the reference time, the PDCCH indicating the SPS PDSCH release and the PDSCH scheduled by the PDCCH cannot transmit HARQ on the first type PUSCH. -ACK to determine which PDSCH and PDCCH indicating SPS PDSCH release in the HARQ-ACK feedback sequence (in codebook) in a time slot can be HARQ-ACK, which PDSCH and PDCCH indicating SPS PDSCH release are not included HARQ-ACK, so as to avoid determining which part of the PDCCH indicating SPS PDSCH release and PDSCH cannot be HARQ-ACK in the current slot according to a UL grant that is further away from the current PUSCH, it will determine too many PDCCH indicating SPS PDSCH release The PDQ and PDSCH cannot perform HARQ-ACK feedback in the current time slot and have to delay the HARQ-ACK feedback of these downlink transmissions to the subsequent time slot transmissions, which greatly reduces the feedback delay of the downlink transmissions, improves system transmission efficiency, and makes The uplink data on the PUSCH and the final HARQ-ACK can perform correct rate matching.
