Abstract

A method for transmitting a HARQ-ACK by a UE is provided. The method receives an SPS configuration. The method then receives a DCI format which activates the SPS configuration and also indicates a first offset for transmitting the HARQ-ACK. After receiving an SPS PDSCH associated with the SPS configuration in a first slot, the method identifies a second slot based on the first slot and the first offset for transmitting the HARQ-ACK. The method determines whether a first PUCCH for transmitting the HARQ-ACK is contained within uplink/flexible symbols of the second slot. When the first PUCCH is not contained within the uplink/flexible symbols and also a parameter that is included in the SPS configuration indicates a deferred HARQ transmission, the method identifies a third slot based on the first slot and a second offset and transmits the HARQ-ACK on a second PUCCH in the third slot.

Description

Transmission of Hybrid Automatic Repeat Request Acknowledgement in Next Generation Networks

The present disclosure relates generally to wireless communications, and more particularly, to the transmission of hybrid automatic repeat request (HARQ)-acknowledgement (ACK) (HARQ-ACK) by user equipment (UE).

With the huge increase in the number of connected devices and the rapid growth of user/network traffic, various efforts have been made to improve different aspects of wireless communication for next-generation wireless communication systems, such as Fifth Generation (5G) new Radio (New Radio, NR), by improving data rate, delay, reliability and mobility. 5G NR systems are designed to provide flexibility and configurability to optimize network services and types for various use cases such as enhanced Mobile Broadband (eMBB), massive Machine-Type Communication (mMTC) ) and Ultra-Reliable and Low-Latency Communication (URLLC).

In the Third Generation Partnership Project (3GPP) Rel-15, a Semi-Persistent Scheduling (SPS) configuration can be configured in the cell group to support periodic services in NR, For example, Voice over IP (Voice over IP, VoIP). In Rel-16, supporting Time Sensitive Networking (TSN) in NR use cases is one of the important goals. In order to support multiple TSN streams simultaneously, multiple semi-persistent scheduling configurations in the Bandwidth Part (BWP) of the User Equipment (UE) may be necessary to reduce the physical downlink control channel ( Physical Downlink Control Channel (PDCCH) signaling overhead. Additionally, the minimum period of the SPS configuration can be reduced (eg, to one slot) to better support TSN streams with shorter periods.

In order to report Hybrid Automatic Retransmission Request for SPS Physical Downlink Shared Channel (PDSCH) for multiple SPS configurations on Physical Uplink Control Channel (PUCCH) configured for SPS HARQ-ACK Acknowledgement (Hybrid Automatic Repeat Request Acknowledgement, HARQ-ACK), multiple PUCCH resources can be configured via SPS-PUCCH-AN-List of each HARQ-ACK codebook. The actual PUCCH resource to be used among the PUCCH resources may be determined based on the size of the HARQ-ACK payload. In such an embodiment, the index may be configured in ascending order of Downlink (DL) time slots for each {SPS configuration index, serving cell index}, and further according to the SPS configuration index for each {serving cell index} , and/or further determine the HARQ-ACK bit order for SPS PDSCH reception without corresponding PDCCH in ascending order of serving cell index.

For Industrial Internet of Thing (IIoT) or TSN use cases, services with low latency requirements and low periodicity can be transported using SPS PDSCH. Since the periodicity of the SPS configuration may be as small as one slot, many of the configured PUCCH resources for SPS PDSCH reception may not be transmitted (eg, may be discarded), for example, when This may affect service reliability and latency when operating in unpaired spectrum for to-UL and/or UL-to-DL switching periods. Therefore, there is room in next-generation networks to define new methods capable of transmitting such HARQ-ACKs in other (eg, delayed) PUCCHs.

As stated above, the present disclosure relates to a method for managing UE behavior in HARQ-ACK transmission associated with SPS PDSCH, the method may include delaying SPS HARQ-ACK feedback (eg, to subsequent time slots of PUCCH resources), A HARQ-ACK codebook is constructed and will be used for multiplexing of PUCCH and other PUCCH or PUSCH for SPS HARQ-ACK.

Memory, EPROM), Electronically Erasable Programmable Read-Only Memory (EEPROM), Flash Memory, Compact Disc Read-Only Memory (CD-ROM) , cassette, magnetic tape, disk storage, or any other equivalent medium capable of storing computer-readable instructions.

Radiocommunication NW architecture (eg, Long Term Evolution (LTE) system, LTE-Advanced (LTE-A) system, LTE-Pro system advanced, or 5G NR Radio Access Network (Radio Access Network) Access Network (RAN)) typically includes at least one base station, at least one UE, and one or more optional network components that provide connectivity to the network. The UE passes through the RAN and networks established by one or more base stations (eg, Core Network (CN), Evolved Packet Core (EPC) network, Evolved Universal Terrestrial Radio Access Network Road (Evolved Universal Terrestrial Radio Access network, e-UTRAN), 5G Core (5G Core, 5GC) or network) communication.

It should be noted that, in the present disclosure, the UE may include, but is not limited to, a mobile station, a mobile terminal or device, and a user communication radio terminal. For example, the UE may be a portable radio device including, but not limited to, a mobile phone with wireless communication capability, a tablet computer, a wearable device, a sensor, or a Personal Digital Assistant (PDA). The UE is configured to receive signals and transmit signals to one or more cells in the RAN through the air interface.

The base station can be configured to provide communication services according to at least one of the following Radio Access Technology (RAT): Worldwide Interoperability for Microwave Access (WiMAX), Global System for Mobile communication (Global System for Mobile communication, Global System for Mobile GSM, commonly referred to as 2G), GSM Enhanced Data rates for GSM Evolution (EDGE) Radio Access Network (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunication System (UMTS, commonly referred to as 3G), High-Speed Packet Access (High-Speed Packet Access, HSPA), LTE, LTE-A, eLTE (evolved LTE, eg, LTE connected to 5GC), NR (commonly referred to as 5G), and/or LTE-A Pro. However, the scope of the present disclosure should not be limited to the aforementioned agreements.

The base station may include but is not limited to a Node B ((Node B, NB) in UMTS, an evolved node B (evolved node B, eNB) in LTE or LTE-A, a Radio Network Controller (Radio Network Controller) in UMTS , RNC), GSM/GSM Enhanced Data Rates for GSM Evolution (Enhanced Data rates for GSM Evolution, EDGE) Radio Access Network (GERAN) Base Station Controller (Base Station Controller, BSC), next-generation eNB (next- generation eNB, ng-eNB) as in Evolved Universal Terrestrial Radio Access (E-UTRA) BS incorporating 5GC, as in 5G Access Network (5G-an) A generation Node B (gNB), and any other device capable of controlling wireless communication and managing wireless resources within a cell. A BS can connect to a network through a wireless interface to serve one or more UEs.

A base station may be operable to provide radio coverage for a particular geographic area using a plurality of cells included in the RAN. BS can support the operation of cells. Each cell is operable to provide service to at least one UE within its radio coverage. More specifically, each cell (commonly referred to as a serving cell) may provide service to serve one or more UEs within its radio coverage, (eg, each cell will downlink (DL) resources and Optional uplink (UL) resources are scheduled to at least one UE within its radio coverage for DL packet transmission and optional UL packet transmission). The BS may communicate with one or more UEs in the radio communication system through a plurality of cells.

Cells can allocate sidelink (SL) resources to support ProSe (ProSe) or Vehicle to Everything (V2X) services. Each cell can have overlapping coverage areas with other cells. In the case of Multi-RAT Dual Connectivity (MR-DC), the master cells of the Master Cell Group (MCG) or Secondary Cell Group (SCG) can be called Special Cells (Special Cell Group). Cell, SpCell). The primary cell (Primary Cell, PCell) may refer to the SpCell of the MCG. Primary SCG cell (PSCell) may refer to the SpCell of the SCG. An MCG may refer to a set of serving cells associated with a master node (MN), including a SpCell and optionally one or more secondary cells (SCell). An SCG may refer to a set of serving cells associated with a secondary node (SN), including a SpCell and optionally one or more SCells.

As previously disclosed, the frame structure for NR supports flexible configuration for accommodating various next-generation (eg, 5G) communication requirements such as Enhanced Mobile Broadband (eMBB), large-scale machine-based communication (Massive Machine Type Communication, mMTC) and ultra-reliable and low-latency communication (Reliable and Low-Latency Communication, URLLC), and meet the requirements of high reliability, high data rate and low delay at the same time. For example, the OFDM disclosed in 3GPP Orthogonal Frequency-Division Multiplexing (OFDM) techniques can be used as a baseline for NR waveforms. Scalable OFDM parameters such as adaptive subcarrier spacing, channel bandwidth, and CP can also be used. In addition, two coding schemes are considered for NR: ( 1) LDPC codes and (2) polar codes. Coding scheme adaptation can be configured based on channel conditions and/or service application.

In addition, it is also considered that the transmission time interval TX of a single NR frame should include at least downlink (DL) transmission data, guard period and uplink (UL) transmission data. The respective parts of the DL transmission data, guard period, UL transmission data should also be dynamically configurable, eg based on NW of NR. For example, NR-based network dynamics. In addition, sidelink resources can also be provided in the NR frame to support ProSe services, (E-UTRA/NR) sidechain services or (E-UTRA/NR) V2X services.

Furthermore, the terms "system" and "network" are used interchangeably herein. The term "and/or" herein is only used to describe the association relationship of the associated objects, and means that three kinds of relationships can exist. For example, A and/or B may mean: A alone, A and B both, or B alone. Also, the character "/" in this document generally indicates that the preceding and succeeding associated objects are in an "or" relationship.

As mentioned above, next-generation (eg, 5G NR) wireless networks are envisioned to support more capacity, data, and services. A UE configured with multiple connections can connect to a master node (Master Node, MN) as an anchor point and one or more secondary nodes (Secondary Node, SN) for data transmission. Each of these nodes may be formed by a cell group comprising one or more cells. For example, the Master Cell Group (MCG) can be formed by MN, and the Secondary Cell Group (SCG) can be formed by SN. In other words, for a UE configured with Dual Connectivity (DC), an MCG is a set of one or more serving cells including a PCell and zero or more secondary cells. Conversely, an SCG is a set of one or more service cells that includes a PSCell and zero or more secondary cells.

Also as described above, the primary cell (Primary Cell, PCell) may be an MCG cell operating on the primary frequency where the UE either performs an initial connection establishment procedure or initiates a connection re-establishment procedure. In MR-DC mode, PCell may belong to MN. A Primary SCG Cell (PSCell) may be an SCG cell in which the UE performs random access (eg, when performing reconfiguration with synchronization procedures). In MR-DC, PSCell may belong to SN. Depending on whether the MAC entity is associated with the MCG or with the SCG, a Special Cell (SpCell) may be referred to as the PCell of the MCG or the PSCell of the SCG. Otherwise, the term special cell may refer to PCell. Special cells can support Physical Uplink Control Channel (PUCCH) transmission and Contention-Based Random Access (CBRA) and can always be enabled. In addition, for the UE in the RRC_CONNECTED state that is not configured with the CA/DC, it may communicate with only one serving cell (Serving Cell, SCell), and the serving cell may be the master cell. Conversely, for a UE in RRC_CONNECTED state configured with CA/DC, a set of service cells including special cells and all secondary cells can communicate with the UE.

Furthermore, the term bandwidth fraction (BWP) may be a subset of the total cellular bandwidth of a cell. BWP adaptation may be achieved by configuring the UE with BWPs and informing the UE which of the configured BWPs are currently active BWPs. In some embodiments, in order to enable Bandwidth Adaptation (BA) on the PCell, the gNB may configure UL and DL BWP for the UE. In some such embodiments, to enable BA on SCell with Carrier Aggregation (CA), the gNB may configure the UE with at least one DL BWP (eg, a BWP that may not be configured in the UL). In some embodiments, for PCells, the initial BWP may be the BWP for initial access. In some embodiments, for one or more SCells, the initial BWP may be for the UE-configured BWP to operate first when the SCell is enabled. In some embodiments, the UE may be configured with the first Active Uplink BWP through a firstActiveUplinkBWP Information Element (IE). In some embodiments, if the first active UL BWP is configured for SpCell, the firstActiveUplinkBWP IE field may contain the ID of the UL BWP to be enabled when performing RRC configuration or RRC reconfiguration. In some embodiments, RRC configuration or RRC reconfiguration may not enforce BWP handover if this field is not present. In some embodiments, if the first active UL BWP is configured for the SCell, the firstActiveUplinkBWP IE field may contain the ID of the UL BWP to be used when the SCell's MAC is enabled.

As mentioned above, the term HARQ-ACK may include the term Hybrid Automatic Repeat Request (HARQ) and the term Acknowledgement/Non-Acknowledgement (ACK/NACK). The term HARQ may be a scheme combining an Automatic Repeat Request (ARQ) error control mechanism and Forward Error Correction (FEC) coding, where unsuccessful attempts are used in FEC decoding rather than discarded. In some embodiments, HARQ-ACK feedback may be used to indicate whether the HARQ process was performed successfully.

Furthermore, the term Code Block Group (CBG) may refer to code blocks of Transport Blocks (TB) grouped together. Each CBG may include the same or a different number of code blocks. In some embodiments, CBG-based retransmissions may be scheduled to carry multiple CBGs of a TB.

In some embodiments, HARQ-ACK corresponding to PDSCH dynamically scheduled by Downlink Control Information (DCI) or SPS release scheduled by DCI and SPS PDSCH for multiple SPS configurations The HARQ-ACK of the multiplexed, when reporting the HARQ-ACK for the SPS PDSCH for multiple SPS configurations, the PUCCH may be determined based on, for example, DCI. In some embodiments, the HARQ-ACK codebook used for the SPS configuration may be determined by Radio Resource Control (RRC) parameters configured in the SPS PDSCH configuration.

In some embodiments, if a Type 1 HARQ-ACK codebook is used to report HARQ-ACK for SPS configuration, the HARQ-ACK bit position (eg, the HARQ-ACK bit position within the HARQ-ACK codebook for SPS PDSCH) location) may be derived based on a Time Domain Resource Allocation (TDRA) table column index and an indicated offset (eg, K1 ), eg, in enabling DCI. In some such embodiments, for SPS PDSCH release with a separate release DCI (eg, release one SPS-configured DCI) based on the TDRA table list index indicated in the enable DCI and the offset K1 indicated in the release DCI The HARQ-ACK bit positions can be derived. In some embodiments, the HARQ-ACK bit position for SPS PDSCH release with joint release DCI may be based on the TDRA table column indicated in the enabled DCI of the SPS PDSCH with the lowest SPS configuration index in the joint release configuration The index and the offset K1 indicated in the release DCI are derived.

In some embodiments, if a Type 2 HARQ-ACK codebook is used to report SPS-configured HARQ-ACK, based on the Downlink Assignment Index (DAI) and the offset indicated in the release DCI (eg, K1) , the HARQ-ACK bit order for DCI SPS PDSCH release with individual/joint release can be derived. In some embodiments, the HARQ-ACK bit positions within the HARQ-ACK codebook for the SPS PDSCH with the associated PDCCH may be derived based on the offset (eg, K1 ) in DAI and enabled DCI. In some embodiments, HARQ-ACK bits for SPS PDSCHs without corresponding PDCCHs may be appended to HARQ-ACK bits for dynamically scheduled PDSCH and/or SPS PDSCH releases. In some embodiments, it may be in ascending order of DL slots per {SPS configuration index, serving cell index}, and further in ascending order of SPS configuration index per {serving cell index}, and/or further in accordance with The ascending order of the serving cell index determines the HARQ-ACK bit order.

In some embodiments, the HARQ-ACK codebook for SPS HARQ-ACK bits may also be referred to as Type 1 HARQ-ACK when transmitted in PUCCH resources configured to transmit only SPS HARQ-ACK bits codebook. The Type-1 HARQ-ACK codebook here may also be referred to as the Type-1 HARQ-ACK codebook transmitted in PUCCH resources scheduled by DCI formats (eg, DCI format 1_0, DCI format 1_1, and DCI format 1_2) ).

In Rel-16, the UE may be configured with two HARQ-ACK codebooks. In some embodiments, if the UE is provided with the pdsch-HARQ-ACK-Codebook-List, the UE may be instructed (eg, via the pdsch-HARQ-ACK-Codebook-List) to generate one or more HARQ-ACK codes Book. In some embodiments, if the UE is instructed to generate one HARQ-ACK codebook, the one HARQ-ACK codebook may be associated with the PUCCH with priority index "0". In some embodiments, if the UE is provided with a pdsch-HARQ-ACK-Codebook-List, the UE may multiplex the same HARQ-ACK codebook with HARQ-ACK information associated only with the same priority index. In some embodiments, if the UE is instructed to generate two HARQ-ACK codebooks, the first HARQ-ACK codebook may be associated with the PUCCH with priority index "0" (eg, low priority), and the Two HARQ-ACK codebooks may be associated with PUCCH with priority index "1" (eg, high priority), and the UE may provide { PUCCH- Config, UCI-OnPUSCH, PDSCH-codeBlockGroupTransmission } for use with the first and second HARQ-ACK codebooks.

In some embodiments, various methods may be implemented to determine PUCCH resources for transmitting HARQ-ACK bits. In some embodiments, if the UE transmits 0 _UCI UCI information bits including HARQ-ACK information bits, the UE may determine the PUCCH resource set to be one of the following four PUCCH resource sets: A PUCCH resource set that satisfies the following conditions: If O _UCI ≤ 2, UCI information includes 1 or 2 HARQ-ACK information bits, and includes a positive Schedule Request (SR) or negative SR on an SR transmission opportunity , if the transmission of HARQ-ACK information and SR occur simultaneously; a second PUCCH resource set with pucch-ResourceSetId = 1, and the following conditions are met: if pucch-ResourceSetId = 1 is provided by higher layers, and if 2 < O _UCI ≤ N ₂ , where N equals maxPayloadSize if maxPayloadSize is provided for the PUCCH resource set with pucch-ResourceSetId = ₁ , otherwise N equals 1706; the third PUCCH resource set with pucch-ResourceSetId = ₂ , and the following conditions are met: if pucch - ResourceSetId = 2 is provided by higher layers and if N ₂ < O _UCI ≤ N ₃ , where if maxPayloadSize is provided for a PUCCH resource set with pucch-ResourceSetId = 2, then N ₃ is equal to maxPayloadSize, otherwise N3 is equal to 1706; or with pucch - Fourth PUCCH resource set with ResourceSetId=3, and satisfy the following conditions: if pucch-ResourceSetId= ₃ is provided by higher layers, and if N3< O _UCI≤1706 .

In some embodiments, the UE may determine the PUCCH if the UE is provided with the SPS-PUCCH-AN-List and transmits 0 _UCI UCI information bits including only HARQ-ACK information bits in response to one or more SPS PDSCH receptions The resource is one of the following four kinds of PUCCH resources: PUCCH resource with SPS-PUCCH-AN-ResourceID=0, and satisfy the following conditions, if O _UCI ≤2; PUCCH resource with SPS-PUCCH-AN-ResourceID=1, and The following conditions are met: if SPS-PUCCH-AN-ResourceID = 1 is provided, if 2 < O _UCI ≤ N _1,SPS , where N _1,SPS consists of SPS-PUCCH- for SPS-PUCCH-AN-ResourceID = 1 maxPayloadSize in AN-List provided, or otherwise N _{1, SPS} equal to 1706; PUCCH resource with SPS-PUCCH-AN-ResourceID = 2, and the following conditions are met: if SPS-PUCCH-AN-ResourceID = 2 is provided, if N _1,SPS < O _UCI ≤ N _2,SPS , where N _2,SPS is provided by maxPayloadSize in SPS-PUCCH-AN-List for SPS-PUCCH-AN-ResourceID = 2, or otherwise N _2,SPS is equal to 1706; or PUCCH resources for SPS-PUCCH-AN-ResourceID=3, and the following conditions are met: if SPS-PUCCH-AN-ResourceID=3 is provided, if N _2,SPS < O _UCI ≤ N _3,SPS , where N _{3, SPS} is equal to 1706.

In Rel-15 and Rel-16, for unpaired spectrum, when the subset of symbols containing scheduled or configured PUCCH transmissions are semi-static DL symbols or contain Synchronization Signal Block (SSB) , the PUCCH may not be transmitted. In some embodiments, 14 symbols may be in one or more time slots, and the direction (eg, uplink or downlink) of each of the 14 symbols may be configured by time slot tdd - UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated semi-statically configured. FIG. 1 is a schematic diagram illustrating a typical 5G NR frame structure according to example embodiments of the present disclosure. For example, slot 100 may include 14 symbols (eg, symbol 0 to symbol 13), each configured as a symbol (eg, D, F, U), as shown in FIG. 1 . Symbol 0 to symbol 5 may be configured with symbols indicated as Downlink (DL) symbols (eg, D), and symbols 6 and 7 may be configured with symbols indicated as flexible Symbols of symbols (eg, F), and symbols 8 to 13 may be configured with symbols indicated as uplink (UL) symbols (eg, U). If PUCCH transmission is configured in symbols 4 to 13 (eg, patterned with oblique lines), as shown in FIG. 1, since PUCCH is contained in a DL symbol (eg, D), PUCCH may not be transmitted, At least because symbol 4 and symbol 5 can be pre-configured with a DL symbol (eg, D). In other words, PUCCH may collide with DL symbols (eg, D), at least in symbol 4 and symbol 5.

As described above, the present disclosure provides a UE and a method for managing UE behavior for HARQ-ACK transmission associated with SPS PDSCH, which may include delaying SPS HARQ-ACK feedback, constructing a HARQ-ACK codebook, and/or multiplexing of PUCCH and other PUCCH or PUSCH to be used for SPS HARQ-ACK.

In some embodiments, for a time slot initially configured for the PUCCH resource of the SPS HARQ-ACK, delaying the transmission of the SPS HARQ-ACK to any time slot after that time slot may facilitate unsuccessful rescheduling Received/decoded SPS PDSCH. In some embodiments, the UE may configure and/or indicate the PUCCH resources used to delay transmission of the SPS HARQ-ACK bits.

In some embodiments of the present disclosure, the UE may be provided with PUCCH resources for transmission of delayed HARQ-ACK bits corresponding to SPS PDSCH reception. In some embodiments, if subslotLength-ForPUCCH is provided to the UE, the slot may include sub-slots, which may indicate the number of symbols of the sub-slot used for the associated PUCCH transmission. To provide additional opportunities to transmit, for example, HARQ-ACK bits corresponding to SPS PDSCH reception configured in slot "n", PUCCH resources in slot "n+k+d" may be provided. The offset "k" may be the number of time slots indicated by the PDSCH-to-HARQ_feedback timing indicator field in the corresponding DCI format of the SPS configuration used to enable SPS PDSCH reception, or provided by the dl-DataToUL-ACK feedback, If the PDSCH-to-HARQ_feedback timing indicator field is not present in the corresponding DCI format. Another offset "d" may be greater than or equal to 0 and may be determined based on one or a combination of the following embodiments. In some such implementations, when offset "d"=0, the SPS HARQ-ACK bits may be treated as non-delayed SPS HARQ-ACK bits.

In some embodiments, the offset "d" may be a value or values selected from a set of values. In some such embodiments, the maximum value in the value set may be preconfigured or predefined and the value set may include all integers less than or equal to the maximum value. In some embodiments, the PUCCH resources configured by SPS-PUCCH-AN-List-r16 may be selected for transmitting only SPS HARQ-ACK bits and non-delayed SPS in the slot based on the delayed total payload size PUCCH resource for HARQ-ACK bits. An example of the above method can be shown in FIG. 2 .

FIG. 2 is a schematic diagram of delayed HARQ-ACK transmission based on PUCCH corresponding to SPS PDSCH according to an example embodiment of the present disclosure. In some embodiments, example time slots, as shown in FIG. 2 , may include time slot 202A (eg, time slot 0 ), time slot 202B (eg, time slot 1 ), time slot 202C (eg, time slot 2 ), time slot 202C (eg, time slot 2 ), 202D (eg, time slot 3) and time slot 202E (eg, time slot 4). Time slots 202A, time slots 202B, and time slots 202C may each be configured with one or more DL symbols (eg, causing them to become unpatterned time slots) while time slots 202D and time slots 202E may each be configured with one or more DL symbols. Multiple UL symbols (eg, cause them to be patterned slots). SPS PDSCH 204 may be transmitted in time slot 202A (eg, time slot "n") and PUCCH 206A corresponding to the HARQ-ACK of SPS PDSCH 204 may be configured in time slot 202B based on offset k=1. However, in some embodiments, PUCCH 206A configured in slot 202B may not be transmittable to the base station, eg, because PUCCH 206A collides with DL symbols in slot 202B (eg, PUCCH 206A is in unformatted slot 202B) or configured in slot 202B with DL symbols).

In some such embodiments, when PUCCH 206A is not transmittable in time slot 202B (eg, when the PUCCH collides with one or more DL symbols in time slot 202B), the UE may first determine certain parameters (eg, Also included in the SPS configuration) whether to indicate a delay in the corresponding HARQ transmission (eg, when a particular bit representing a parameter is set to 1). When certain parameters indicate to delay HARQ transmission, the UE may determine to configure another PUCCH 206B (eg, corresponding to the same SPS PDSCH 204 ) in time slot 202D based on offset k=1 and another offset d=2 for use in time slot 202D Transmission of HARQ-ACK. In some embodiments, the UE may determine the offset d, and may subsequently identify the time slot 202D as this time slot is (in the time domain) between the time slot 202B and the largest time slot (eg, time slot 202E) The earliest time slot that includes a sufficient number of uplink (and/or flexible) symbols to carry the PUCCH 206B.

In some implementations, even a PUCCH 206A configured in a slot 202B may be configured with a DL symbol in the slot 202B (eg, configured in a non-patterned slot 202B or a slot 202B with DL symbols) PUCCH 206A) collision, the UE may determine to discard HARQ if a certain parameter (eg, included in the SPS configuration) does not indicate delayed HARQ transmission (eg, when a certain bit representing the parameter is set to zero) - ACK, eg, instead of transmitting PUCCH 206A in the first available uplink time slot.

In some embodiments of the present disclosure, when one or more HARQ-ACK bits corresponding to (eg, the first) SPS PDSCH are delayed (eg, by delayed HARQ-ACK parameters included in the SPS configuration) indication), there may be other one or more HARQ-ACK bits corresponding to another (eg, second) SPS PDSCH configured in the same time slot. In some such embodiments, the other one or more HARQ-ACK bits corresponding to other SPS PDSCHs of the same or different SPS configuration may be one or more non-delayed HARQ-ACK bits. An example of some such implementations may be shown in Figure 3, which is a schematic diagram of delayed HARQ-ACK transmission based on PUCCH corresponding to multiple SPS PDSCHs of one or more SPS configurations.

In some embodiments, the example time slots shown in FIG. 3 may include time slot 302A (eg, time slot 0), time slot 302B (eg, time slot 1), time slot 302C (eg, time slot 2), time slot 302D (eg slot 3) and slot 302E (eg slot 4). Time slot 302A, time slot 302B, and time slot 302C may each be configured with one or more DL symbols (eg, causing them to become unpatterned time slots), while time slot 302D and time slot 302E may each be configured with one or multiple UL symbols (eg, causing them to be patterned time slots). The first SPS PDSCH 304A of SPS configuration 1 may be transmitted in time slot 302A, and the PUCCH corresponding to the HARQ-ACK of the first SPS PDSCH 304A of SPS configuration 1 may be based on offset k2=1 and another offset d1 = 2 is delayed to slot 302D. In other words, based on time slot 302A with offset k2=1 and offset d1=2, the HARQ-ACK bit corresponding to the first SPS PDSCH 304A of SPS configuration 1 in 302A may be delayed to time slot 302D . The second SPS PDSCH 304B of SPS configuration 2 may be transmitted in time slot 302B and the PUCCH for the HARQ-ACK corresponding to the second SPS PDSCH 304B of SPS configuration 2 may be based on offset k2=2 and offset d1 =0 is configured in the same slot 302D. In other words, based on the offset k2 = 2 and the offset d1 = 0, by correspondingly enabling the PDSCH-to-HARQ_feedback field in the DCI, the HARQ-ACK of the second SPS PDSCH 304B corresponding to the SPS configuration 2 in the time slot 302B The bit may be indicated to be transmitted 2 time slots after the second SPS PDSCH 304B (eg, in the same time slot 302D).

In this way, the delayed HARQ-ACK bits corresponding to the first SPS PDSCH 304A of SPS configuration 1 and the non-delayed HARQ-ACK bits corresponding to the second SPS PDSCHE 304B of SPS configuration 2 can be allocated to the same time slot 302D. In some embodiments, the UE may determine to transmit delayed HARQ-ACK bits corresponding to the first SPS PDSCH 304A of SPS configuration 1 and non-delayed HARQ-ACK bits corresponding to the second SPS PDSCH 304B of SPS configuration 2 The element is in the same slot 302D on a new PUCCH (eg, PUCCH 306). The new PUCCH corresponds to the first SPS PDSCH 304A and the second SPS PDSCH 304B. In some such embodiments, the UE may determine whether to transmit the delayed and non-delayed HARQ-ACK bits on the third PUCCH 306 based on the payload size of the delayed and non-delayed HARQ-ACK.

In some implementations, the new PUCCH resource (eg, third PUCCH 306) in slot 302D may be determined based on the total payload size of delayed and non-delayed HARQ-ACK bits. In some embodiments, when the total payload size is below a threshold number of bits (eg, 2 bits), the PUCCH resource may be in the SPS-PUCCH-AN-List with SPS-PUCCH-AN-ResourceID=0. Configured PUCCH resources. In some embodiments, when the total payload size is greater than a threshold number of bits and less than a second threshold number of bits, the PUCCH resource may be in the SPS-PUCCH-AN-List with SPS-PUCCH-AN-ResourceID=1 The configured PUCCH resource. In some embodiments, when the total payload size is greater than a second threshold number of bits and less than a third threshold number of bits, the PUCCH resource may be SPS-PUCCH-AN- at SPS-PUCCH-AN-ResourceID=2 The configured PUCCH resources in the List. In some embodiments, when the total payload size is greater than a third threshold number of bits and less than a fourth threshold number of bits, eg, 1706 bits, the PUCCH resource may be SPS at SPS-PUCCH-AN-ResourceID=3 - PUCCH resources configured in PUCCH-AN-List. It should be noted that the SPS-PUCCH-AN-List can be configured for PUCCH or not configured with SPS-PUCCH-AN-ResourceID = 1, SPS-PUCCH-AN-ResourceID = 2 and SPS-PUCCH-AN-ResourceID = 3 . In some such embodiments, if the total payload size exceeds the maximum allowed size (eg, above a threshold number of bits), the BS may configure the appropriate SPS configuration and PUCCH resources to accommodate both delayed and non-delayed HARQ-ACKs The PUCCH resources can always be available to the UE for transmission of delayed and non-delayed HARQ-ACK.

As mentioned above, in some embodiments of the present disclosure, the offset "d" may be a value or values selected from a set of values. In some embodiments, the maximum value in the value set may be preconfigured or predefined and the value set may include all integers less than or equal to the maximum value. An example of such an implementation may be shown in FIG. 4 . This is a schematic diagram of delaying HARQ-ACK transmission based on the PUCCH corresponding to the SPS PDSCH according to another embodiment of the disclosure. In some embodiments, the example slots shown in FIG. 4 may include slot 402A (eg, slot 0), slot 402B (eg, slot 1), slot 402C (eg, slot 2), slot 402D (eg, time slot 3) and time slot 402E (eg, time slot 4). Time slot 402A, time slot 402B, and time slot 402C may each be configured with one or more DL symbols (eg, causing them to become unpatterned time slots), while time slot 402D and time slot 402E may each be configured with one or multiple UL symbols (eg, causing them to be patterned time slots). In some embodiments, the offset "d" may be a value in a set of values {0, 1, 2, 3}. SPS PDSCH 404 may be transmitted in slot 402A and a PUCCH (eg, first PUCCH) 406A for HARQ-ACK corresponding to SPS PDSCH 404 may be configured in slot 402B based on offset k=1. However, in some embodiments, the first PUCCH 406A in the slot 402B may not be transmittable to the base station, eg, because the first PUCCH 406A collides with the DL symbol in the slot 402B (eg, is configured in a non-patterned slot 402B or first PUCCH 406A in slot 402B with DL symbols).

Therefore, the UE may not transmit HARQ-ACK on the first PUCCH 406A in slot 402B and may determine another PUCCH 406B in slot 402C based on offset k=1 and another offset d=1 (eg, , and transmit HARQ-ACK on the second PUCCH). Furthermore, in some embodiments, the second PUCCH 406B in slot 402C may also collide with a DL symbol in slot 402C (eg, a slot configured in unpatterned slot 402C or a slot with DL symbols) second PUCCH 406B in 402C). In some embodiments, the UE may iteratively check subsequent time slots until the UE reaches a time slot with UL symbols or flexible symbols, or until the UE reaches a threshold number of check iterations. For example, when the first PUCCH 406A corresponding to the HARQ-ACK of the SPS PDSCH 404 collides with one or more DL symbols in slot 402B, the UE may iteratively check subsequent slots until there are one or more UL symbols The next available slot (eg, slot 402D) for a symbol or flexible symbol is reached, or until the UE reaches a threshold number of check iterations (eg, the UE may be configured with a threshold number of two check iterations, which may allow The UE only checks the two subsequent time slots with UL symbols or flexible symbols after time slot 402B. Therefore, the UE may further determine not to transmit HARQ-ACK on the second PUCCH 406B in time slot 402C and determine in time slot 402D The HARQ-ACK is transmitted on the third PUCCH 406C in the HARQ-ACK because the third PUCCH 406C may be transmitted to the base station, for example, because the third PUCCH 406C may not match the UL symbol based on offset k=1 and another offset d=2 Element collision (eg, third PUCCH 406C to be transmitted in patterned time slot 402D, or in time slot 402D with UL symbols).

In some embodiments, the set of values may be an SPS configuration specific configuration. In other words, the set of values may be different for different SPS configurations. In some embodiments, the maximum value of the offset "d" may be a number of time slots that is a multiple of the period of the SPS configuration for SPS PDSCH reception. In some embodiments, the maximum value of the offset "d" may be a value of the number of time slots such that "k+d" is a multiple of the period of the SPS configuration for SPS PDSCH reception.

In some embodiments, the offset "d" may be based on slot configuration tdd-UL-DL-ConfigurationDedicated or tdd-UL-DL-ConfigurationCommon and PUCCH resource related configuration (eg, PUCCH-Config and SPS-Config or SPS-PUCCH-AN-List-r16 ).

5 is a flowchart illustrating a method/process for transmitting HARQ-ACK by a UE according to an example embodiment of the present disclosure. As shown in FIG. 5 , process 500 may begin by receiving a semi-persistent scheduling (SPS) configuration in act 502 . In some embodiments, receiving the SPS configuration may include receiving the SPS configuration via radio resource control (RRC) signaling. After receiving the SPS configuration, process 500 may receive, in act 504, an enabled downlink control information (DCI) format indicating the SPS configuration. In some such embodiments, the DCI format may also indicate a first offset (eg, offset k) for transmitting the HARQ-ACK. In act 506, process 500 may also receive an SPS entity downlink shared channel (PDSCH) associated with the SPS configuration in a first time slot (eg, time slot n).

After receiving the DCI format indicating the first offset, process 500 may, in act 508, identify a second time slot based on the first time slot (eg, time slot n) and the first offset (eg, time slot k) (eg, slot n+k) for transmission of HARQ-ACK on the first physical uplink control channel (PUCCH) corresponding to the SPS PDSCH. After identifying the second time slot for transmission of the HARQ-ACK on the first PUCCH, process 500 may determine in act 510 whether the first PUCCH is contained in one or more symbols in the second time slot, the first One or more symbols in two time slots are uplink symbols or flexible symbols. In some embodiments, when the first PUCCH is determined to be contained within one or more symbols, process 500 may proceed to act 520 described below. On the other hand, when it is determined that the first PUCCH is not included in one or more symbols, process 500 may proceed to act 512, which may further determine whether a particular parameter included in the SPS configuration indicates delayed HARQ transmission .

If a particular parameter included in the SPS configuration is determined to indicate non-delayed HARQ transmission (eg, the bit representing the parameter is set to zero), process 500 may proceed to act 518 described below. On the other hand, when a particular parameter included in the SPS configuration is determined to indicate delayed HARQ transmission (eg, the bit representing the parameter is set to 1), process 500 may be based on the first time slot and the second offset (eg, offset d), a third slot (eg, slot n+k+d) is identified in act 514 for transmission of HARQ-ACK on the second PUCCH corresponding to the SPS PDSCH.

In some embodiments, the second offset may be greater than the first offset (eg, d>k) and the second PUCCH may be contained in one or more symbols in the third time slot, in the third time slot One or more of the symbols are uplink symbols or flexible symbols. In some such embodiments, the one or more symbols in the third time slot may be semi-static uplink symbols or semi-static flexible symbols. In some embodiments, the second offset may be determined based on identifying the earliest particular time slot in time between the second time slot and the largest time slot. In some such embodiments, a particular time slot may include a sufficient number of uplink or flexible symbols for carrying the second PUCCH. In some embodiments, the second offset may be less than the maximum value, which is also included in the SPS configuration.

In some embodiments, after identifying the third time slot for transmitting the HARQ-ACK on the second PUCCH, the process 500 may also transmit, in act 516, the HARQ-ACK on the second PUCCH in the third time slot.

In some embodiments, as described above, when process 500 reaches act 510 and determines that the first PUCCH is not contained within one or more symbols, process 500 may proceed to act 512, which may further determine that the SPS is contained Whether a specific parameter in the configuration indicates delayed HARQ transmission. If certain parameters included in the SPS configuration are determined not to indicate delayed HARQ transmission, process 500 may proceed to act 518, where the UE may discard the HARQ-ACK.

In some embodiments, when process 500 reaches act 510 and determines that the first PUCCH is contained within one or more symbols, as described above, process 500 may proceed to act 520, where the UE may HARQ-ACK is transmitted on the first PUCCH in the slots. In this case, process 500 may transmit the HARQ-ACK on the first PUCCH in the second slot, regardless of whether the particular parameter indicates to delay the HARQ transmission. That is, when the first PUCCH is contained within one or more symbols, the process 500 may not investigate the status of a particular parameter and without knowing whether the parameter indicates delayed HARQ transmission, at the first time slot in the second slot HARQ-ACK is transmitted on a PUCCH.

FIG. 6 is a flow chart further illustrating the method/process of FIG. 5 . According to example embodiments of the present disclosure. In some embodiments, after identifying a third time slot for transmission of HARQ-ACK on the second PUCCH corresponding to the SPS PDSCH, as shown in act 514 of FIG. 5, process 500 may proceed to act 602 (eg, , instead of proceeding to act 516 shown in FIG. 5 ). In act 602, process 500 may receive a second SPS configuration. After receiving the second SPS configuration in act 602, process 500 may also receive, in act 604, a second DCI format enabling the second SPS configuration. In some embodiments, the second DCI format may also indicate a third offset for transmitting the second HARQ-ACK. Process 500 may also receive, in act 606, a second SPS PDSCH associated with the second SPS configuration in a fourth time slot.

In some embodiments, when the third time slot identified in act 514 for transmitting the HARQ-ACK is also identified based on the fourth time slot and the third offset for transmitting the second HARQ-ACK (eg, The third time slot identified for transmission of the HARQ-ACK in act 514 may be the same time slot configured for transmission of the second HARQ-ACK), the process 500 may be in act 608 in conjunction with the SPS PDSCH and the Instead of proceeding to action, the HARQ-ACK (eg, in act 514) and the second HARQ-ACK (eg, in act 604) are transmitted on the third PUCCH corresponding to the second SPS PDSCH in the third time slot 516, in which the UE may transmit only HARQ-ACK on the second PUCCH in the third time slot. In some embodiments, the third PUCCH may be determined based on the payload size of the second HARQ-ACK and the payload size of the HARQ-ACK.

As described above, the present disclosure may provide management of UE behavior for HARQ-ACK transmission of SPS PDSCH through HARQ-ACK codebook construction. Specifically, defining the size of the HARQ-ACK codebook for PUCCH resources that transmit only SPS HARQ-ACK bits and the ordering of the SPS HARQ-ACK bits are necessary to construct the HARQ-ACK codebook. It can be achieved by some examples This is achieved by constructing a HARQ-ACK codebook for the PUCCH resources provided by the UE to report only SPS HARQ-ACK bits. For example, the example pseudocode "m - n ≤ k + d _max "" may be used to construct a HARQ-ACK codebook for PUCCH resources in the UL slot "m" provided for the UE to report only SPS HARQ-ACK Bit(s). HARQ-ACK information received by SPS PDSCH in a DL slot that overlaps with UL slot "n" may be multiplexed in PUCCH resources in UL slot "m". In some embodiments , the offset "k" may be the number of UL time slots indicated by the PDSCH-to-HARQ_feedback timing indication field in the corresponding DCI format for the initiation of the SPS configuration for SPS PDSCH reception, or if the There is no PDSCH-to-HARQ_feedback timing indication field in the DCI format, then the offset "k" can be provided by dl-DataToUL-ACK, and the offset " _dmax " can be SPS PDSCH received HARQ-ACK information can be delayed The maximum number of _UL slots in ) and the corresponding HARQ-ACK information can be multiplexed in PUCCH resources.
