Description

The present invention relates to terminals and base stations in wireless communication systems.

In 3GPP (3rd Generation Partnership Project), in order to further increase system capacity, further increase data transmission speed, further reduce delay in wireless sections, etc., 5G or NR (New Radio) is being developed. Studies are progressing on a wireless communication system called "NR" (hereinafter referred to as "NR"). In 5G, various wireless technologies and network architectures are being studied in order to meet the requirements of achieving a throughput of 10 Gbps or more while reducing the delay in the wireless section to 1 ms or less.

In addition, NR specifies downlink SPS (Semi-Persistent Scheduling) in which PDSCH resources are set in advance in the terminal and activation/release is performed by the DCI, which makes it possible to receive data with low delay. (For example, Non-Patent Documents 1 and 2).

3GPP TS 38.213 V16.3.0 (2020-09) 3GPP TS 38.331 V16.2.0 (2020-09)

If a UL slot is placed after multiple consecutive DL slots, the terminal may transmit multiple HARQ-ACKs corresponding to reception of multiple data in the UL slot after the DL slot. If the payload load (density of information included in the payload) of HARQ-ACK is high, the reliability of HARQ-ACK may decrease.

Furthermore, in the case of postponing HARQ-ACK transmission, the next first available PUCCH resource is selected autonomously by the terminal without being instructed by the base station. Collisions between the transmission of HARQ-ACK and the deferred transmission of HARQ-ACK by other terminals may occur.

When using UL cancellation indication (CI) to avoid collisions between the transmission of a deferred HARQ-ACK by one terminal and the transmission of a deferred HARQ-ACK by another terminal, The deferred HARQ-ACK transmission will be dropped rather than being further deferred. That is, it is not intended to use UL CI to avoid collisions between the transmission of a deferred HARQ-ACK by one terminal and the transmission of a deferred HARQ-ACK by another terminal. .

The present invention has been made in view of the above points, and an object of the present invention is to provide a technique that allows a terminal that has received data to appropriately transmit feedback information regarding data reception to a base station.

Embodiments of the present invention will be described below with reference to the drawings. Note that the embodiment described below is an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

Existing technology may be used as appropriate for the operation of the wireless communication system according to the embodiment of the present invention. The existing technology is, for example, existing NR or LTE, but is not limited to existing NR or LTE.

(System configuration)
FIG. 1 is a diagram for explaining a wireless communication system according to an embodiment of the present invention. A wireless communication system according to an embodiment of the present invention includes a base station 10 and a terminal 20, as shown in FIG. Although FIG. 1 shows one base station 10 and one terminal 20, this is just an example, and there may be a plurality of each.

The base station 10 is a communication device that provides one or more cells and performs wireless communication with the terminal 20. The physical resources of a radio signal are defined in the time domain and the frequency domain, and the time domain may be defined by the number of OFDM symbols, and the frequency domain may be defined by the number of subcarriers or the number of resource blocks. Further, a TTI (Transmission Time Interval) in the time domain may be a slot, or a TTI may be a subframe.

The base station 10 can perform carrier aggregation in which a plurality of cells (a plurality of CCs (component carriers)) are bundled to communicate with the terminal 20. In carrier aggregation, one PCell (primary cell) and one or more SCells (secondary cells) are used.

The base station 10 transmits a synchronization signal, system information, etc. to the terminal 20. The synchronization signals are, for example, NR-PSS and NR-SSS. System information is transmitted, for example, on NR-PBCH or PDSCH, and is also referred to as broadcast information. As shown in FIG. 1, the base station 10 transmits a control signal or data to the terminal 20 via DL (Downlink), and receives the control signal or data from the terminal 20 via UL (Uplink). Note that here, what is transmitted on control channels such as PUCCH and PDCCH is called a control signal, and what is transmitted on shared channels such as PUSCH and PDSCH is called data. It is.

The terminal 20 is a communication device equipped with a wireless communication function, such as a smartphone, a mobile phone, a tablet, a wearable terminal, or a communication module for M2M (Machine-to-Machine). As shown in FIG. 1, the terminal 20 receives control signals or data from the base station 10 via DL, and transmits control signals or data to the base station 10 via UL, thereby receiving various types of information provided by the wireless communication system. Use communication services. Note that the terminal 20 may be called a UE, and the base station 10 may be called a gNB.

The terminal 20 can perform carrier aggregation in which a plurality of cells (a plurality of CCs (component carriers)) are bundled to communicate with the base station 10. In carrier aggregation, one PCell (primary cell) and one or more SCells (secondary cells) are used. Also, a PUCCH-SCell with PUCCH may be used.

FIG. 2 shows a configuration example of a wireless communication system when DC (dual connectivity) is implemented. As shown in FIG. 2, a base station 10A serving as an MN (Master Node) and a base station 10B serving as an SN (Secondary Node) are provided. Base station 10A and base station 10B are each connected to a core network. Terminal 20 can communicate with both base station 10A and base station 10B.

A cell group provided by the base station 10A, which is an MN, is called an MCG (Master Cell Group), and a cell group provided by the base station 10B, which is an SN, is called an SCG (Secondary Cell Group). Furthermore, in the DC, the MCG is composed of one PCell and one or more SCells, and the SCG is composed of one PSCell (Primary SCell) and one or more SCells.

The processing operations in this embodiment may be executed with the system configuration shown in FIG. 1, with the system configuration shown in FIG. 2, or with a system configuration other than these.

(Basic operation example)
With reference to FIG. 3, a basic operational example of the communication system according to the embodiment of the present invention will be described. This operation is basically common to Examples 1 to 10, which will be described later.

In S101, the base station 10 transmits downlink SPS configuration information, PUCCH resource configuration information, slot format configuration information, etc. to the terminal 20 by RRC signaling, and the terminal 20 receives these configuration information. Note that since this embodiment is directed to downlink SPS, "SPS" hereinafter means downlink SPS.

The configuration information of the slot format is, for example, tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, and this configuration information allows the TDD configuration of each symbol of each slot in one or more slots to be DL, UL, It is set whether it is flexible or not. Hereinafter, this configuration information will be referred to as semi-static TDD configuration information. Also, flexible may be written as F. The terminal 20 basically determines the DL/UL/F of each symbol of each slot according to the semi-static TDD setting information.

Further, as the setting information in S101, a plurality of slot format candidates may be notified to enable dynamic switching of slot formats. This setting information is, for example, SlotFormatCombinationsPerCell. Since this information is information consisting of a slot format (SF) ID, it will be referred to as SFI setting information hereinafter.

In S102, the terminal 20 receives a DCI that activates the SPS settings from the base station 10, and in S103 receives data using the PDSCH resource according to the SPS settings. In S104, the terminal 20 transmits SPS HARQ-ACK to the base station 10 using the PUCCH resource (or the PUSCH resource if there is UL scheduling) in the slot at the time position specified by the DCI. Note that SPS HARQ-ACK is sometimes referred to as HARQ-ACK. Furthermore, HARQ-ACK may be called HARQ information, feedback information, or the like.

The terminal 20 may receive a DCI that dynamically specifies the slot format from the base station 10 at or before S102. This DCI is control information that specifies the ID to be actually used among the plurality of slot format IDs set in the SFI setting information. When the slot format is specified by this DCI, the terminal 20 determines the DL/UL/F of each symbol of each slot according to the slot format instead of the semi-static TDD setting information. This DCI information is called dynamic SFI designation information (or dynamic SFI, or SFI).

(About the assignment)
As described above, each time the terminal 20 receives data by SPS, the activation DCI specifies the time position (slot) at which the terminal 20 transmits HARQ-ACK using the PUCCH resource.

However, especially when multiple short-cycle SPSs are configured in the terminal 20, TDD DL/UL configuration in a slot at a specified time position (configuration based on semi-static TDD configuration information or dynamic SFI specification information) In some cases, the symbol position where the PUCCH resource is set may collide with the DL symbol or the F symbol, making it impossible to transmit HARQ-ACK.

When a PUCCH resource collides with a DL symbol or an F symbol, it is possible to drop HARQ-ACK, but dropping HARQ-ACK requires retransmission of PDSCH. Therefore, dropping HARQ-ACK increases the delay, which is undesirable.

(Summary of embodiment)
FIG. 4 shows an example of a collision as described above. In the example of FIG. 4, the third slot from the slot immediately after the slot in which the PDSCH is received is designated as a slot for HARQ-ACK transmission. ACK is dropped.

In this embodiment, it is possible to avoid dropping HARQ-ACK due to collision between PUCCH resources and DL symbols/F symbols.

Specifically, for example, as shown in FIG. 4, when the terminal 20 determines that a collision between the PUCCH resource and the DL symbol/F symbol will occur, the terminal 20 postpones HARQ until the next available UL resource. - Send an ACK.

(Detailed issues related to embodiment)
At the 3GPP meeting, R. It has been agreed that 17 enhancements will be made.

Candidates A to G below can be considered as enhancement methods to avoid dropping SPS HARQ-ACK due to collision of PUCCH with at least one "DL or F symbol".

Candidate A: The terminal 20 postpones HARQ-ACK until the first available valid PUCCH resource.

Candidate B: The terminal 20 selects the first applicable K1 value from the set of configured K1 values to enable HARQ-ACK load balancing.

Candidate C: The base station 10 dynamically notifies the terminal 20 of one or more transmission opportunities for postponed HARQ-ACK.

Candidate D: The base station 10 notifies the terminal 20 of the K1 value of each SPS transmission within the time window set by RRC.

Candidate E: Supports one-shot HARQ-ACK requests (ie, Type 3 HARQ-ACK Codebook) for a group of SPS HARQ processes.

Candidate F: Supports non-numeric values (ie, Non Numerical K1) for DL SPS operations in the licensed spectrum.

Candidate G: Autonomously retransmit HARQ-ACK or multiplex dropped HARQ-ACK information with another HARQ-ACK information.

Regarding at least Candidate A and Candidate B, the terminal 20 needs to determine whether a collision between HARQ-ACK and "DL symbol or F symbol" will occur by applying the K1 value specified in the activation DCI. Since the HARQ-ACK is transmitted on the first available valid PUCCH resource, the terminal 20 also needs to determine the validity of the PUCCH resource.

However, in the existing technology, the exact meaning of "DL symbol or F symbol" is unclear. In other words, it is unclear for the terminal 20 how to determine whether the PUCCH resource is valid. This will be referred to as "Problem 1."

Hereinafter, the DL, UL, and F set by the semi-static TDD setting information will be referred to as semi-static DL, semi-static UL, and semi-static F, respectively. Further, DL, UL, and F designated by the dynamic SFI designation information will be described as dynamic DL, dynamic UL, and dynamic F, respectively. Further, UL set by scheduling is referred to as dynamic UL scheduling or the like.

Hereinafter, an example of determining the validity of PUCCH regarding the above-mentioned "DL symbol or F symbol" will be explained in more detail by case.

(1) When there is no dynamic UL scheduling on semi-static F symbol <1-1: When SFI is not set>
If SFI is not configured (if there is no configuration in SFI configuration information), there is a possibility of SSB/CORESET#0 configuration or dynamic DL scheduling, so if PUCCH can be transmitted in semi-static F symbol, It may not be possible.

That is, if SSB/CORESET #0 reception is set for the symbol, or if DL reception by DCI is scheduled for the symbol, the PUCCH in the symbol is invalid and the PUCCH is dropped. In other cases, the PUCCH resource in the symbol is valid.

<1-2: When SFI is set>
When SFI is configured, even if the base station 10 instructs the semi-static F symbol as a dynamic UL, there is a possibility that the terminal 20 will not receive the dynamic SFI (because there is a possibility of SFI missing). , PUCCH may or may not be transmitted. That is, when the terminal 20 detects SFI, the symbol is valid for PUCCH. If the terminal 20 cannot detect the SFI, the symbol is invalid for the PUCCH, and the PUCCH is dropped.

If the base station 10 indicates semi-static F symbols as dynamic DL, PUCCH is dropped. If the base station 10 indicates a semi-static F symbol as a dynamic F, the PUCCH is dropped.

(2) When there is dynamic UL scheduling on a semi-static F symbol The symbol is always valid for PUCCH, regardless of the presence or absence of SFI setting. Note that when SFI is set, it is not assumed that dynamic DL is set for the symbol.

<About detailed assignments>
Regarding Ultra-Reliable and Low Latency Communication (URLLC) of Release 16 of 3GPP, when one or more short-cycle downlink Semi-Persistent Scheduling (SPS) settings are performed for the terminal 20, in the activation DCI , since a single HARQ-ACK feedback timing value is indicated, multiple Physical Uplink Control Channels for SPS Hybrid Automatic Repeat Request (HARQ) transmission can be used, especially when downlink communication is congested. Conflicts between (PUCCH) resources and slot formats specified by quasi-static time division multiplexing configurations or dynamic slot format identifiers (SFIs) may occur.

When reusing the New Radio (NR) Release 15 mechanism for multiple SPS configurations, physical downloads associated with dropping colliding HARQ-ACK transmissions (transmission of HARQ acknowledgment information) It is assumed that retransmission of the Shared Channel (PDSCH) will be performed.

3GPP meeting avoids dropping SPS HARQ-ACK in case of TDD due to PUCCH collision (e.g. collision between downlink (DL) or flexible symbol (F) and resource transmitting PUCCH) It is envisaged that an extension of Release 17 will be made in order to do so.

(Assignment 1)
When the payload load of HARQ-ACK (density of information included in the payload) is high, the reliability of HARQ-ACK may decrease.

FIG. 5 is a diagram illustrating an example of a case where the reliability of HARQ-ACK may deteriorate. In the example of FIG. 5, five consecutive DL slots are set in the time domain, followed by two UL slots.

Regarding SPS PDSCH1 in the first DL slot in the time domain in the example of FIG. 5, the terminal 20 attempts to transmit HARQ-ACK in the second slot from the beginning in the time domain based on the K1 value. Since the second slot is a DL slot, the terminal 20 postpones the transmission of HARQ-ACK until the next available first UL slot, which is the sixth slot from the first in the time domain.

Similarly, the terminal 20 postpones the transmission of HARQ-ACK for SPS PDSCH3 and SPS PDSCH5, shown in the example of FIG. 5, until the sixth slot from the first in the time domain.

Furthermore, the terminal 20 transmits SPS PDSCH 2, SPS PDSCH 4, and SPS PDSCH 6 in the sixth slot from the beginning in the time domain based on the K1 value.

As a result, in the example of FIG. 5, the payload load of HARQ-ACK transmitted in the UL resource, which is the sixth slot from the first in the time domain, becomes high, which may reduce the reliability of HARQ-ACK. .

(Assignment 2)
The PUCCH load of the first available UL slot/subslot after one DL slot/subslot or a plurality of consecutive DL slots/subslots is such that the plurality of terminals 20 transmit the deferred HARQ-ACK to the corresponding It can be high because there is a possibility of transmitting in the first available UL slot/subslot.

(Assignment 3)
In the case of postponing the transmission of SPS HARQ-ACK, the next first available PUCCH resource is selected autonomously by the terminal 20 without being instructed by the base station 10. , a collision between the transmission of the deferred HARQ-ACK and the transmission of the deferred HARQ-ACK by another terminal 20 may occur (if HARQ-ACK for dynamic PDSCH and SPS HARQ are not multiplexed) , or multiplexing SPS HARQ with other PUCCHs or PUSCHs).

FIG. 6 is a diagram illustrating an example of a collision between a postponed transmission of HARQ-ACK by one terminal 20 and a postponed transmission of HARQ-ACK by another terminal 20.

In the example of FIG. 6, in the time domain, the first slot to the fifth slot in the time direction are set as DL slots. In the time direction, the first to sixth slots are set as UL slots.

In the first slot in the time direction, the terminal 20#1 receives the SPS PDSCH. Based on the K1 value, the terminal 20#1 attempts to transmit HARQ-ACK regarding reception of the SPS PDSCH in the first to third slots in the time direction. However, in the time direction, the first to third slots are DL slots. Therefore, the terminal 20#1 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 6, the terminal 20#1 transmits HARQ-ACK in the sixth slot from the first slot in the time direction.

Furthermore, in the slot following the first slot in the time direction, the terminal 20#2 receives the SPS PDSCH. Based on the K1 value, the terminal 20#2 attempts to transmit HARQ-ACK regarding reception of the SPS PDSCH in the first to fifth slots in the time direction. However, in the time direction, the first to fifth slots are DL slots. Therefore, the terminal 20#2 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 6, the terminal 20#2 transmits HARQ-ACK in the sixth slot from the first slot in the time direction.

As a result, a collision may occur between the transmission of HARQ-ACK by terminal 20#1 and the transmission of HARQ-ACK by terminal 20#2.

FIG. 7 is a diagram showing an example of using UL cancellation indication (CI).

As shown in the example of Figure 7, when using Downlink Control Information (DCI) format 2_4 (UL cancellation indication (CI)), the postponed HARQ-ACK transmission is dropped instead of being further postponed. It turns out. The purpose of the UL CI is to give priority to the URLLC terminal 20 over the eMBB terminal 20. In the case of SPS HARQ, the UL CI is used to avoid collisions between the transmission of a deferred HARQ-ACK by one terminal 20 and the transmission of a deferred HARQ-ACK by another terminal 20. This is not expected.

(Proposal 1)
A pattern of resource regions applicable to the transmission of HARQ-ACK for the SPS PDSCH (hereinafter may be referred to as "applicable resource region pattern") is used to set the time and frequency domain resource regions to the SPS PDSCH. It may be indicated to the terminal 20 whether or not the terminal can be used for transmitting HARQ-ACK for.

SPS HARQ resources (resources for transmitting HARQ-ACK for SPS PDSCH) are available because the symbol direction is UL, and additional conditions for deferring SPS HARQ transmission (transmission of HARQ-ACK for SPS PDSCH) (For example, the max K1 limitation, which states that PUCCH resources exceeding the maximum value of K1 are not valid), the SPS HARQ resource can be used by the terminal 20 to transmit HARQ-ACK for the SPS PDSCH. It may be.

If the SPS HARQ resource according to the SPS HARQ resource pattern overlaps with an inappropriate resource area, the terminal 20 cannot use the SPS HARQ resource for SPS HARQ transmission, and the terminal 20 cannot use the SPS HARQ resource for SPS HARQ transmission. , may be deferred until the next SPS HARQ resource that satisfies the conditions for sending the HARQ-ACK for the SPS PDSCH.

If the SPS HARQ resource according to the SPS HARQ resource pattern does not overlap with an inappropriate resource area, the terminal 20 may use the SPS HARQ resource for SPS HARQ transmission.

If the SPS HARQ resource is invalid because the symbol direction is DL, the terminal 20 is not expected to use the SPS HARQ resource for SPS HARQ transmission. If the SPS HARQ resources are invalid because the symbol direction is DL, the terminal 20 determines whether to further postpone SPS HARQ transmission based on whether the max K1 limitation is satisfied. Good too.

For example, based on the max K1 limitation condition that PUCCH resources that exceed the maximum value of K1 are not valid, the time interval between the resource that received the SPS PDSCH and the next available SPS HARQ resource is set to the maximum value of K1. If the value is not exceeded, the terminal 20 may postpone the transmission of SPS HARQ to the next available SPS HARQ resource, and the terminal 20 may postpone the transmission of SPS HARQ to the next available SPS HARQ resource, and the terminal 20 may postpone the transmission of SPS HARQ to the next available SPS HARQ resource, and The SPS HARQ transmission may be dropped if the time interval between the two times exceeds the maximum value of K1.

The applicable resource region pattern may only operate on SPS HARQ resources. In other words, if the resources for the transmission of deferred SPS HARQ are multiplexed with other PUCCH resources (e.g., if deferred SPS HARQ is transmitted together with dynamic HARQ in dynamic HARQ resources, or if the channel state information If the CSI of the resource and the resource for the postponed SPS HARQ transmission are multiplexed), the applicable resource area pattern is set so as not to affect the transmission of other PUCCH resources. May be set.

FIG. 8 is a diagram illustrating an example of an applicable resource area pattern. In the example of FIG. 8, in the time domain, the first slot to the fifth slot in the time direction are set as DL slots. In the time direction, the 6th and 7th slots from the first slot are set as UL slots.

In the example of FIG. 8, the first to sixth slots in the time direction are the first available UL slots after the DL slots. However, in the first to sixth slots in the time direction, the higher resource regions in the frequency direction are inappropriate resources for SPS HARQ transmission. Therefore, the applicable resource area pattern is a resource area with a lower frequency in the first slot to the sixth slot in the time direction, and a resource area with a lower frequency in the first slot to the seventh slot in the time direction. region and a resource region with a higher frequency. In the example of FIG. 8, the terminal 20 receives the SPS PDSCH in the first slot in the time domain, and determines the reception of the SPS PDSCH in the third slot from the first slot in the time domain based on the K1 value. Attempt to send HARQ-ACK. However, in the time direction, the first to third slots are DL slots. Therefore, the terminal 20 selects a resource area applicable to transmission of HARQ-ACK regarding reception of PS PDSCH based on the applicable resource area pattern, and performs SPS HARQ transmission in the selected resource area. In the example of FIG. 8, the terminal 20 selects a resource region with a lower frequency in the first to seventh slots in the time direction as a resource for performing SPS HARQ transmission.

A bitmap may be used by the base station 10 to indicate to the terminal 20 a resource area pattern applicable to SPS HARQ transmission. For example, one bit may be used for one resource area.

When the base station 10 notifies the terminal 20 of the bitmap, it is possible to use, for example, the DCI format and/or RRC signaling. In the following, the configuration of SPS PDSCH transmission to which the bitmap indicating the resource area pattern applicable to SPS HARQ transmission is applied may be referred to as "SPS configuration".

(Example of terminal operation)
When postponing SPS HARQ-ACK, the following three conditions may be defined for SPS HARQ resources.

Condition A: SPS HARQ resources are effective when considering the symbol direction.

Condition B: If there is an additional condition regarding the postponement of SPS HARQ (for example, max K1 limitation that states that PUCCH resources exceeding the maximum value of K1 are not valid), the additional condition is satisfied.

Condition C: The applicable resource area pattern does not overlap with an inappropriate resource area. Here, the inappropriate resource area may be, for example, a PUCCH resource in which dynamic HARQ-ACK transmission is performed using a dynamic HARQ resource, or a PUCCH resource in which channel state information (CSI) is transmitted.

Note that in the following embodiments, it is assumed that SPS HARQ-ACK and dynamic HARQ are not multiplexed, or SPS HARQ-ACK and other PUCCHs are not multiplexed.

Case 1 and Case 2 below are considered as operations when the terminal 20 uses the applicable resource area pattern for SPS settings.

Case 1: The terminal 20 applies the same applicable resource area pattern to all SPS configurations in which SPS HARQ-ACK deferral is enabled.

Case 2: The terminal 20 applies a plurality of corresponding different applicable area patterns to a plurality of SPS settings in which SPS HARQ-ACK postponement is enabled.

Condition C above may only be considered for SPS configurations where HARQ-ACK must be sent on SPS HARQ resources. In other words, if one SPS configuration is activated but no HARQ-ACK is transmitted for that SPS configuration in the SPS HARQ resources, condition C need not be considered for that SPS configuration. .

In the following, case 1 will be described, which is a case where the terminal 20 applies the same applicable resource area pattern to all SPS configurations in which SPS HARQ-ACK deferral is enabled. Case 1 may be classified into case 1-1 and case 1-2.

Case 1-1: For multiple SPS HARQ-ACKs (e.g., with X bits, which may or may not include deferred/non-deferred HARQ-ACKs), the first used in the time direction If possible SPS HARQ resources satisfy Condition A, Condition B, and Condition C at the same time. In this case, the terminal 20 may transmit a HARQ Codebook (CB) including multiple SPS HARQ-ACKs of X bits using the first available SPS HARQ resource.

FIG. 9 is a diagram showing an example of case 1-1. In the example of FIG. 9, in the time domain, the first slot to the fifth slot in the time direction are set as DL slots. In the time direction, the first to sixth slots are set as UL slots.

In the first slot in the time direction, the terminal 20 receives SPS PDSCH1. Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK for reception of SPS PDSCH1 in the slot following the first slot in the time direction. However, in the time direction, the next slot after the first slot is a DL slot. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 9, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH1 in the sixth slot from the first slot in the time direction.

Furthermore, in the third slot from the first slot in the time direction, the terminal 20 receives SPS PDSCH2. Based on the K1 value, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH2 in the first to sixth slots in the time direction.

Furthermore, in the fourth slot from the first slot in the time direction, the terminal 20 receives SPS PDSCH3. Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH3 in the first to fifth slots in the time direction. However, in the time direction, the first to fifth slots are DL slots. Therefore, the terminal 20 postpones the transmission of HARQ-ACK for reception of SPS PDSCH3 until the first available UL slot after the DL slot. In the example of FIG. 9, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH3 in the sixth slot from the first slot in the time direction.

In this case, the first to sixth slots satisfy Condition A, Condition B, and Condition C at the same time in the time direction. Therefore, the terminal 20 transmits the HARQ CB including HARQ-ACK for reception of SPS PDSCH1, HARQ-ACK for reception of SPS PDSCH2, and HARQ-ACK for reception of SPS PDSCH3 from the first slot to the sixth slot. You can also send it by .

Case 1-2: For multiple SPS HARQ-ACKs (e.g., may or may not include deferred HARQ-ACK/non-deferred HARQ-ACK), the first available SPS HARQ in the time direction A case where the resource satisfies conditions A and B, but does not satisfy condition C. In this case, the terminal 20 transmits the HARQ CB including multiple SPS HARQ-ACKs of X bits using the earliest in the time direction among the SPS HARQ resources that simultaneously satisfy conditions A, B, and C. It may be deferred until the SPS HARQ resources of the location. If there is no SPS HARQ resource that satisfies conditions A, B, and C at the same time, the terminal 20 may drop the transmission of the HARQ CB (eg, may drop it according to condition B).

In the first slot in the time direction, the terminal 20 receives SPS PDSCH1. Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK for reception of SPS PDSCH1 in the slot following the first slot in the time direction. However, in the time direction, the next slot after the first slot is a DL slot. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 10, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH1 in the sixth slot from the first slot in the time direction. However, the sixth slot from the first slot in the time direction satisfies condition A and condition B, but does not satisfy condition C.

Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK for reception of SPS PDSCH1 in the slot following the first slot in the time direction. However, in the time direction, the next slot after the first slot is a DL slot. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 11, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH1 in the sixth slot from the first slot in the time direction.

However, in the time direction, the next slot after the first slot is a DL slot. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 12, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH1 in the sixth slot from the first slot in the time direction. However, the sixth slot from the first slot in the time direction satisfies condition A and condition B, but does not satisfy condition C.

Furthermore, in the third slot from the first slot in the time direction, the terminal 20 receives SPS PDSCH2. Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH2 in the first to fifth slots in the time direction. However, the first to fifth slots in the time direction are DL slots. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 12, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH2 in the sixth slot from the first slot in the time direction. However, the sixth slot from the first slot in the time direction satisfies condition A and condition B, but does not satisfy condition C.

Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK for reception of SPS PDSCH1 in the slot following the first slot in the time direction. However, in the time direction, the next slot after the first slot is a DL slot. Therefore, the terminal 20 postpones the transmission of HARQ-ACK until the first available UL slot after the DL slot. In the example of FIG. 13, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH1 in the sixth slot from the first slot in the time direction. The first to sixth slots in the time direction satisfy Condition A, Condition B, and Condition C for the applicable resource area pattern of SPS configuration 1. However, the first to sixth slots in the time direction satisfy conditions A and B for the applicable resource area pattern of SPS configuration 3, but do not satisfy condition C.

Based on the K1 value, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH3 in the first to fifth slots in the time direction. However, in the time direction, the first to fifth slots are DL slots. Therefore, the terminal 20 postpones the transmission of HARQ-ACK for reception of SPS PDSCH3 until the first available UL slot after the DL slot. In the example of FIG. 13, the terminal 20 attempts to transmit HARQ-ACK regarding reception of SPS PDSCH3 in the sixth slot from the first slot in the time direction. However, the first to sixth slots in the time direction satisfy conditions A and B for the applicable resource area pattern of SPS configuration 3, but do not satisfy condition C. Therefore, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH3 based on conditions A, B, and C for the applicable resource area pattern of each SPS configuration among SPS configurations 1, 2, and 3. Defer from the first slot to the seventh slot in the time direction, filling simultaneously.

(Option 2)
In option 2 of case 2-3 above, the terminal 20 determines that the first available SPS HARQ resource in the time domain is the remaining SPS settings (for example, SPS setting 1, Conditions A and B for the applicable resource area pattern of SPS configuration 3) of 2 and 3 are satisfied, but condition C is not satisfied, so condition A is used for HARQ-ACK transmission for the remaining SPS configurations. , Condition B, and Condition C may be postponed until the SPS HARQ resource satisfies Condition B and Condition C at the same time.

The terminal 20 transmits HARQ-ACK for some of the SPS configurations in the same slot/subslot (i.e., in consideration of reducing the payload load of HARQ-ACK). , without changing the current K1 value), reselection of SPS HARQ resources may be performed.

In the example of FIG. 14, the first to sixth slots in the time direction are UL slots, and satisfy conditions A, B, and C for the applicable resource area patterns of SPS settings 1 and 2. Therefore, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH1 and SPS PDSCH2 in the sixth slot from the first slot.

Further, the sixth slot from the first slot in the time direction is a UL slot, and satisfies conditions A and B for the applicable resource area pattern of SPS setting 3, but does not satisfy condition C. Therefore, the terminal 20 transmits HARQ-ACK regarding reception of SPS PDSCH3 from the first slot in the time direction that simultaneously satisfies conditions A, B, and C for the applicable resource area pattern of SPS configuration 3. Postponed to 7th slot.

Case 2-4: For multiple SPS HARQ-ACKs (e.g., with X bits, including deferred and non-deferred HARQ-ACKs), the first available PUCCH resource in the time direction is Conditions A and B for the applicable resource area pattern of at least one of the SPS settings are satisfied, but condition C is not satisfied.

(Option 1) In this case, the terminal 20 transmits HARQ-ACK as in Case 2-2 or Case 2-3 above, without distinguishing between HARQ that has not been postponed and HARQ that has been postponed. You may go.

(Option 2)
The terminal 20 may transmit a non-postponed HARQ-ACK with priority over a postponed HARQ-ACK. In other words, the terminal 20 may further postpone the postponed HARQ-ACK. In consideration of reducing the payload of HARQ-ACK, the terminal 20 may reselect SPS HARQ resources only for HARQ-ACKs that have not been postponed.

If the reselected SPS HARQ resource satisfies conditions A, B, and C of the applicable resource area pattern of each SPS configuration corresponding to the HARQ-ACK that has not been postponed, the terminal 20 determines that the reselected SPS HARQ resource has not been postponed. HARQ-ACK may be sent on the reselected SPS HARQ resources.

If the reselected SPS HARQ resource satisfies conditions A and B of the applicable resource area pattern of each SPS configuration corresponding to the HARQ-ACK that has not been postponed, but does not satisfy condition C, the terminal 20 postpones the reselected SPS HARQ resource. The transmission of unused HARQ-ACKs may be further postponed together with the transmission of postponed HARQ-ACKs.

(Option 3)
The terminal 20 may transmit the postponed HARQ-ACK with priority over the non-postponed HARQ-ACK. In other words, the terminal 20 may further postpone the HARQ-ACK that has not been postponed. The terminal 20 may reselect SPS HARQ resources only for the postponed HARQ-ACK in consideration of reducing the payload of the HARQ-ACK.

If the reselected SPS HARQ resource satisfies conditions A, B, and C of the applicable resource area pattern of each SPS configuration corresponding to the postponed HARQ-ACK, the terminal 20 transmits the postponed HARQ-ACK. Transmission may be performed using the reselected SPS HARQ resource.

If the reselected SPS HARQ resource satisfies conditions A and B of the applicable resource area pattern of each SPS configuration corresponding to the postponed HARQ-ACK, but does not satisfy condition C, the terminal 20 uses the postponed HARQ-ACK. The transmission of the ACK may be further postponed along with the transmission of the non-postponed HARQ-ACK.

A radio frame may be composed of one or more frames in the time domain. Each frame or frames in the time domain may be called a subframe. A subframe may also be composed of one or more slots in the time domain. A subframe may have a fixed time length (eg, 1 ms) that does not depend on numerology.

Numerology may be a communication parameter applied to the transmission and/or reception of a signal or channel. Numerology includes, for example, subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, and transceiver It may also indicate at least one of a specific filtering process performed in the frequency domain, a specific windowing process performed by the transceiver in the time domain, and the like.

A slot consists of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbol, SC-FDMA (Single Carrier Frequency Division Multiple Access)) in the time domain. s) symbols, etc.). A slot may be a unit of time based on numerology.

A slot may include multiple minislots. Each minislot may be made up of one or more symbols in the time domain. Furthermore, a mini-slot may also be called a sub-slot. A minislot may be made up of fewer symbols than a slot. PDSCH (or PUSCH) transmitted in time units larger than minislots may be referred to as PDSCH (or PUSCH) mapping type A. PDSCH (or PUSCH) transmitted using minislots may be referred to as PDSCH (or PUSCH) mapping type B.

Radio frames, subframes, slots, minislots, and symbols all represent time units for transmitting signals. Other names may be used for the radio frame, subframe, slot, minislot, and symbol.

In other words, at least one of the subframe and TTI may be a subframe (1ms) in existing LTE, a period shorter than 1ms (for example, 1-13 symbols), or a period longer than 1ms. It may be. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, a base station performs scheduling to allocate radio resources (frequency bandwidth, transmission power, etc. that can be used by each terminal 20) to each terminal 20 on a TTI basis. Note that the definition of TTI is not limited to this.

The TTI may be a transmission time unit of a channel-coded data packet (transport block), a code block, a codeword, etc., or may be a processing unit of scheduling, link adaptation, etc. Note that when a TTI is given, the time interval (for example, the number of symbols) to which transport blocks, code blocks, code words, etc. are actually mapped may be shorter than the TTI.

Note that when one slot or one minislot is called a TTI, one or more TTIs (that is, one or more slots or one or more minislots) may be the minimum time unit for scheduling. Further, the number of slots (minislot number) that constitutes the minimum time unit of the scheduling may be controlled.

A TTI having a time length of 1 ms may be called a normal TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, normal subframe, normal subframe, long subframe, slot, etc. A TTI that is shorter than a normal TTI may be referred to as an abbreviated TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, or the like.

Note that long TTI (for example, normal TTI, subframe, etc.) may be read as TTI with a time length exceeding 1 ms, and short TTI (for example, short TTI, etc.) It may also be read as a TTI having the above TTI length.

A resource block (RB) is a resource allocation unit in a time domain and a frequency domain, and may include one or more continuous subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of the numerology, and may be 12, for example. The number of subcarriers included in an RB may be determined based on newerology.

Additionally, the time domain of an RB may include one or more symbols and may be one slot, one minislot, one subframe, or one TTI long. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

Note that one or more RBs include a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc. May be called.

Further, a resource block may be configured by one or more resource elements (REs). For example, 1 RE may be a radio resource region of 1 subcarrier and 1 symbol.

A Bandwidth Part (BWP) (which may also be referred to as a partial bandwidth, etc.) may refer to a subset of contiguous common resource blocks (RB) for a certain numerology in a certain carrier. Here, the common RB may be specified by an RB index based on a common reference point of the carrier. PRBs may be defined in a BWP and numbered within that BWP.

The BWP may include a UL BWP (UL BWP) and a DL BWP (DL BWP). One or more BWPs may be configured within one carrier for a UE.

At least one of the configured BWPs may be active and the UE may not expect to transmit or receive a given signal/channel outside of the active BWP. Note that "cell", "carrier", etc. in the present disclosure may be replaced with "BWP".
