Abstract

A method for transmitting hybrid automatic repeat request acknowledgement HARQ-ACK by a UE is provided. The method includes receiving a semi-persistent scheduling, SPS, configuration. The method then receives a downlink control information, DCI, format that activates the SPS configuration, the DCI format further indicating a first offset for transmitting the HARQ-ACK. When receiving an SPS PDSCH associated with the SPS configuration in a first time slot, the method identifies a second time slot for transmitting the HARQ-ACK on a first physical uplink control channel PUCCH corresponding to the SPS PDSCH based on the first time slot and the first offset. The method determines whether a first PUCCH for transmitting the HARQ-ACK is included within an uplink symbol or a flexible symbol in the second slot. When the first PUCCH is not included within the uplink symbol or flexible symbol and the parameter included in the SPS configuration indicates a delayed HARQ transmission, the method identifies a third slot for transmitting the HARQ-ACK on a second PUCCH corresponding to the SPS PDSCH based on the first slot and a second offset.

Description

Transmission of hybrid automatic repeat request acknowledgements in next generation networks

Cross Reference to Related Applications

The present application requests the benefit and priority of U.S. provisional application serial No. 63/104,915, entitled "SPS HARQ-ACK TRANSMISSION ENHANCEMENTS," attorney docket No. US82822, filed on even 23, 10/2020, the contents of which are hereby fully incorporated by reference herein.

Technical Field

The present disclosure relates generally to wireless communications, and more particularly, to transmission of hybrid automatic repeat request acknowledgements (hybrid automatic repeat request (HARQ) -Acknowledgement (ACK) HARQ-ACKs) by User Equipment (UEs).

Background

With the tremendous increase in the number of connected devices and the rapid increase in user/network traffic, various efforts have been made to improve various aspects of wireless communication for next generation wireless communication systems, such as fifth generation (5G) New Radios (NRs), by increasing data rates, delays, reliability, and mobility. The 5G NR system aims to provide flexibility and configurability to optimize network services and types, adapting to various use cases, such as enhanced mobile broadband (eMBB), large-scale machine type communication (mMTC), and ultra-reliable low-latency communication (URLLC).

In release 15 of the third generation partnership project (3 GPP), a semi-persistent scheduling (SPS) configuration may be configured in a cell group to support periodic services, such as voice over IP (VoIP), NR. In release 16, supporting a time sensitive network (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 (SPS) configurations may need to be performed in a bandwidth portion (BWP) of a User Equipment (UE) to reduce signaling overhead of a Physical Downlink Control Channel (PDCCH). Furthermore, the minimum period of the SPS configuration may be reduced (e.g., to one slot) to better support shorter period TSN streams.

In order to report hybrid automatic repeat request acknowledgements (HARQ-ACKs) for SPS Physical Downlink Shared Channels (PDSCH) configured for SPS HARQ-ACKs on Physical Uplink Control Channels (PUCCHs), multiple PUCCH resources may be configured by 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 implementation, the HARQ-ACK bit order for SPS PDSCH reception without a corresponding PDCCH may be determined in ascending order of Downlink (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 ascending order of serving cell index.

Regarding industrial internet of things (industrial internet of things, IIoT) or TSN use cases, SPS PDSCH may be used to transmit traffic with low latency requirements and low periodicity. Since the period of SPS configuration may be as small as one slot, many configured PUCCH resources for SPS PDSCH reception may not be transmitted (e.g., may be dropped), for example, when having longer DL-to-UL and/or UL-to-DL switching periods, which may affect reliability and latency of traffic. Thus, there is room in the next generation network to define new methods, such HARQ-ACKs can be transmitted in other (e.g., delayed) PUCCHs.

Disclosure of Invention

As described above, the present disclosure relates to a method for managing UE behavior in HARQ-ACK transmissions associated with SPS PDSCH, which may include delaying SPS HARQ-ACK feedback (e.g., delaying time slots to subsequent PUCCH resources), constructing HARQ-ACK codebook, and multiplexing PUCCH for SPS HARQ-ACK and other PUCCH or PUSCH.

A first aspect of the present disclosure provides a method of UE transmitting HARQ-ACKs. The method includes receiving a semi-persistent scheduling, SPS, configuration. The method receives a DCI format indicating activation of the SPS configuration. The DCI format also indicates a first offset for transmitting the HARQ-ACK. The method receives an SPS PDSCH associated with the SPS configuration in a first time slot. The method identifies a second slot for transmitting the HARQ-ACK on a first physical uplink control channel PUCCH corresponding to the SPS PDSCH based on the first slot and the first offset. The method determines whether the first PUCCH is included within an uplink symbol or a flexible symbol in the second slot. When the first PUCCH is not included within the one or more symbols and a particular parameter included in the SPS configuration indicates a delayed HARQ transmission, the method identifies a third slot for transmitting the HARQ-ACK on a second PUCCH corresponding to the SPS PDSCH based on the first slot and a second offset. The second offset is greater than the first offset and the second PUCCH is contained within one or more symbols in the third slot, the one or more symbols in the third slot being uplink symbols or flexible symbols. The method also transmits a HARQ-ACK on the second PUCCH in the third slot. The method further discards the HARQ-ACK when the first PUCCH is not included within the one or more symbols and the particular parameter does not indicate a delayed HARQ transmission.

In one embodiment of the first aspect, the one or more symbols in the third slot are semi-static uplink symbols or semi-static flexible symbols.

In another embodiment of the first aspect, the method further receives the SPS configuration via radio resource control, RRC, signaling.

In another embodiment of the first aspect, the second offset is less than a maximum value included in the SPS configuration.

In another embodiment of the first aspect, the method further transmits the HARQ-ACK on the first PUCCH in the second slot when the first PUCCH is contained within the one or more symbols, regardless of whether the particular parameter indicates the delayed HARQ transmission.

In another embodiment of the first aspect, the second offset is determined based on identifying a particular slot that is earliest in time between the second slot and a largest slot, wherein the particular slot includes a sufficient number of uplink symbols or flexible symbols for carrying the second PUCCH.

In another embodiment of the first aspect, the method further receives a second SPS configuration. The method also receives a second DCI format activating the second SPS configuration. The second DCI format further indicates a third offset for transmitting a second HARQ-ACK. The method also receives a second SPS PDSCH associated with the second SPS configuration in a fourth time slot. When the third slot is previously identified as being used for transmitting the HARQ-ACK, and is also identified as being used for transmitting the second HARQ-ACK based on the fourth slot and the third offset, the method also transmits the HARQ-ACK and the second HARQ-ACK on a third PUCCH corresponding to the SPS PDSCH and the second SPS PDSCH in the third slot, instead of transmitting the HARQ-ACK on the second PUCCH in the third slot. The third PUCCH is determined based on a payload size of the second HARQ-ACK and a payload size of the HARQ-ACK.

In a second aspect, a UE is provided. The UE includes one or more non-transitory computer-readable media storing computer-executable instructions for transmitting HARQ-ACKs. The UE further includes at least one processor coupled with the one or more non-transitory computer-readable media, the at least one processor configured to execute the computer-executable instructions to receive a semi-persistent scheduling, SPS, configuration. The UE is further configured to receive a downlink control information, DCI, format indicating activation of the SPS configuration. The DCI format also indicates a first offset for transmitting the HARQ-ACK. The UE is also configured to receive an SPS PDSCH associated with the SPS configuration in a first time slot. The UE is further configured to identify a second slot for transmitting the HARQ-ACK on a first physical uplink control channel, PUCCH, corresponding to the SPS PDSCH based on the first slot and the first offset. The UE is further configured to determine whether the first PUCCH is contained within one or more symbols in the second slot, the one or more symbols being uplink symbols or flexible symbols. The UE is further configured to identify a third slot for transmitting the HARQ-ACK on a second PUCCH corresponding to the SPS PDSCH based on the first slot and a second offset when the first PUCCH is not included within the one or more symbols and the particular parameter included in the SPS configuration indicates a delayed HARQ transmission, and transmit the HARQ-ACK on a second PUCCH in the third slot when the first PUCCH is not included within the one or more symbols and the particular parameter included in the SPS configuration indicates a delayed HARQ transmission. The second offset is greater than the first offset and the second PUCCH is contained within one or more symbols in the third slot, the one or more symbols in the third slot being uplink symbols or flexible symbols. The UE is further configured to discard the HARQ-ACK when the first PUCCH is not included within the one or more symbols and the particular parameter is not indicative of the delayed HARQ transmission.

In one implementation of the second aspect, the one or more symbols in the third slot are semi-static uplink symbols or semi-static flexible symbols.

In one implementation of the second aspect, the at least one processor is further configured to receive the SPS configuration via radio resource control, RRC, signaling.

In one implementation of the second aspect, the second offset is less than a maximum value included in the SPS configuration.

In one implementation of the second aspect, the at least one processor is further configured to execute the computer-executable instructions to transmit the HARQ-ACK on the first PUCCH in the second slot when the first PUCCH is contained within the one or more symbols, regardless of whether the particular parameter indicates the delayed HARQ transmission.

In one implementation of the second aspect, the second offset is determined based on identifying a particular slot that is earliest in time between the second slot and a largest slot, wherein the particular slot includes a sufficient number of uplink symbols or flexible symbols for carrying the second PUCCH.

In one implementation of the second aspect, the at least one processor is further configured to execute the computer-executable instructions to receive a second SPS configuration. The UE including the at least one processor is further configured to receive a second DCI format activating the second SPS configuration, the second DCI format further indicating a third offset for transmission of a second HARQ-ACK. The UE is also referred to as receiving a second SPS PDSCH associated with the second SPS configuration in a fourth time slot. When the third slot is previously identified as being used for transmitting the HARQ-ACK, and is also identified as being used for transmitting the second HARQ-ACK based on the fourth slot and the third offset, the UE is further configured to transmit the HARQ-ACK and the second HARQ-ACK on a third PUCCH corresponding to the SPS PDSCH and the second SPS PDSCH in the third slot, instead of transmitting the HARQ-ACK on the second PUCCH in the third slot. The third PUCCH is determined based on a payload size of the second HARQ-ACK and a payload size of the HARQ-ACK.

A wireless communication network architecture, such as a long term evolution (Long Term Evolution, LTE) system, an LTE-advanced (LTE-a) system, an LTE-advanced Pro system, or a 5G NR radio access network (Radio 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 communicates with a Network (e.g., core Network (CN), evolved packet Core (Evolved Packet Core, EPC) Network, evolved universal terrestrial radio access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), 5G Core (5 gcore,5 gc), or the internet) via a RAN established by one or more base stations.

It should be noted that, in this application, a UE may include, but is not limited to, a mobile station, a mobile terminal or an apparatus or a user communication radio terminal. For example: the UE may be a portable radio, including but not limited to a mobile phone, tablet computer, wearable device, sensor, vehicle, or personal digital assistant (Personal Digital Assistant, PDA) with wireless communication capability. The UE may be configured to receive and transmit signals over an air interface to one or more cells in a radio access network.

Configuring the base station to provide communication services according to at least one of the following radio access technologies (Radio Access Technology, RAT): worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX), global system for mobile communications (Global System for Mobile Communications, GSM, commonly referred to as 2G), GSM enhanced data rates for GSM Evolution (Enhanced Data rates for GSM Evolution, EDGE) radio access network (GERAN), general packet radio service (General Packet Radio Service, GPRS), wideband code division multiple access (W-CDMA) based universal mobile communication system (Universal Mobile Telecommunications System, UMTS, commonly referred to as 3G), high-speed packet access (High-Speed Packet Access, HSPA), LTE-a, evolved Long-Term Evolution (ehte), such as LTE linked to 5GC, NR (commonly referred to as 5G) and/or LTE-a Pro. However, the scope of the present application should not be limited to the above protocols.

The base stations may include, but are not limited to, node B (NB) in UMTS, evolved node B (eNB) in LTE or LTE-a, radio network controller (Radio Network Controller, RNC) in UMTS, base station controller (Base Station Controller, BSC) in GSM/GSM enhanced GSM evolution data rates (Enhanced Data rates for GSM Evolution, EDGE) radio access network (GERAN), next generation eNB (ng-eNB) in evolved universal terrestrial radio access (E-UTRA) BS coupled to 5GC, next generation node B (gNB) in 5G access network (5G-AN), and any other device capable of controlling radio communications and managing radio resources within a cell. The BS may serve one or more UEs over a radio interface to the network.

A base station may be operable to provide radio coverage to a particular geographic area using a plurality of cells included in the RAN. The BS may support operation of the cell. Each cell may be operable to provide service to at least one UE within its radio coverage area. Specifically, each cell (commonly referred to as a serving cell) may provide services to serve one or more UEs within its radio coverage (e.g., each cell schedules Downlink (DL) resources and optional Uplink (UL) resources to at least one UE within its radio coverage for DL and optional UL packet transmissions). The BS may communicate with one or more UEs in a radio communication system through a plurality of cells.

The cell may allocate Sidelink (SL) resources to support proximity services (Proximity Service, proSe) or internet of vehicles (Vehicle to Everything, V2X) services. Each cell may have a coverage area overlapping with other cells. In the case of Multi-RAT dual connectivity (Multi-RAT Dual Connectivity, MR-DC), the primary cell of the primary cell group (Master Cell Group, MCG) or secondary cell group (Secondary Cell Group, SCG) may be referred to as a special cell (SpCell). A Primary Cell (PCell) may refer to the SpCell of the MCG. A primary SCG cell (PSCell) may refer to the SpCell of an SCG. 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 (scells). 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 described above, the frame structure of the NR supports flexible configuration to accommodate various next generation (e.g., 5G) communication requirements, such as: enhanced mobile broadband (enhanced Mobile Broadband, emmbb), large-scale machine type communication (Massive Machine Type Communication, mctc), ultra-Reliable and Low-delay communication (URLLC), while meeting high reliability, high data rate and Low-delay requirements. As agreed in 3GPP, orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) techniques can be used as a baseline for NR waveforms. An extensible OFDM parameter set may also be used, such as: adaptive subcarrier spacing, channel bandwidth and Cyclic Prefix (CP). In addition, two coding schemes for NR are considered: (1) Low-Density Parity-Check (LDPC) and (2) polarization codes. Coding scheme adaptation may be configured based on channel conditions and/or service applications.

Furthermore, it is also contemplated that at least Downlink (DL) transmission data, guard-time segmentation and Uplink (UL) transmission data should be included in the transmission time interval TX of a single NR frame, wherein the respective parts of DL transmission data, guard-time segmentation, UL transmission data should also be configurable, for example: NR based network dynamics. In addition, side link resources may also be provided in NR frames to support ProSe services, (E-UTRA/NR) side link services or (E-UTRA/NR) V2X services.

In addition, the terms "system" and "network" are used interchangeably herein. The term "and/or" is used herein merely to describe the association of associated objects and indicates that there may be three relationships. For example: a and/or B may indicate: a is present alone, A and B are present simultaneously, or B is present alone. In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.

As described above, the next generation (e.g., 5G NR) wireless network will support more capacity, data, and services. A UE configured with multiple connections may be connected to a Master Node (MN) as an anchor and one or more Secondary Nodes (SN) for data transfer. Each of these nodes may be formed by a group of cells including one or more cells. For example, a primary cell group (Master Cell Group, MCG) may be formed by MN and a secondary cell group (Secondary Cell Group, SCG) may be formed by SN. In other words, for a UE configured with dual connectivity (dual connectivity, DC), the MCG is a set of one or more serving cells, including a PCell and zero or more secondary cells. In contrast, an SCG is a set of one or more serving cells that includes a PSCell and zero or more secondary cells.

As described above, a Primary Cell (PCell) may be an MCG Cell operating on a Primary frequency, in which a UE performs an initial connection establishment procedure or initiates a connection re-establishment procedure. In MR-DC mode, the PCell may belong to the MN. A Primary SCG Cell (PSCell) may be an SCG Cell in which a UE performs random access (e.g., when performing reconfiguration using a synchronization procedure). In MR-DC, PScell may belong to SN. A Special Cell (SpCell) may refer to a PCell of an MCG or a PSCell of an SCG, depending on whether a MAC entity is associated with the MCG or the SCG. Otherwise, the term special unit may refer to a PCell. The special cell may support physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission and contention-based random access (CBRA), and may be activated all the time. In addition, for a UE in an rrc_connected state without CA/DC configuration, it may communicate with only one serving cell (SCell) that is a primary cell. In contrast, for a UE in rrc_connected state using CA/DC configuration, a set of serving cells including a special cell and all secondary cells may communicate with the UE.

Furthermore, the term bandwidth part (BWP) may be a subset of the total cell bandwidth of a cell. BWP adaptation may be achieved by configuring BWP for the UE and informing the UE which configured BWP is currently active. In some implementations, to enable Bandwidth Adaptation (BA) on the PCell, the gNB may configure UL and DL BWP for the UE. In some such implementations, to enable BA on the SCell in the case of Carrier Aggregation (CA), the gNB may configure at least one DL BWP for the UE (e.g., BWP may not be configured in UL). In some implementations, for the PCell, the initial BWP may be a BWP for initial access. In some implementations, for the SCell, the initial BWP may be a BWP configured for the UE to operate first upon SCell activation. In some implementations, the UE may be configured with the first active uplink UL BWP through a first actionuplinkbwp Information Element (IE). In some implementations, if the first active UL BWP is configured for SpCell, the firstActiveUplinkBWP IE field may contain an ID of the UL BWP to be activated when performing RRC configuration or RRC reconfiguration. In some implementations, if this field does not exist, the RRC configuration or RRC reconfiguration may not force BWP handover. In some implementations, if the first active UL BWP is configured for the SCell, the firstActiveUplinkBWP IE field may contain an ID of the UL BWP to be used upon MAC activation of the SCell.

As described above, the term HARQ-ACK may include the term hybrid automatic repeat request (HARQ) and the term acknowledgement/not 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 for FEC decoding instead of being discarded. In some implementations, HARQ-ACK feedback may be used to indicate whether the HARQ process performed successfully.

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

In some embodiments, HARQ-ACKs for SPS PDSCH configured for multiple SPS are reported, multiplexed with HARQ-ACKs corresponding to dynamically scheduled PDSCH or SPS release scheduled by Downlink Control Information (DCI), e.g., PUCCH may be determined based on the DCI. In some implementations, the HARQ-ACK codebook for SPS configuration may be determined by Radio Resource Control (RRC) parameters configured in SPS PDSCH configuration.

In some implementations, if a type 1HARQ-ACK codebook is used to report HARQ-ACKs for SPS configuration, the location of HARQ-ACK bits for SPS PDSCH (e.g., a location within the HARQ-ACK codebook) may be derived based on, for example, a Time Domain Resource Allocation (TDRA) table row index indicated in the activation DCI and an offset (e.g., K1). In some such implementations, the location of the HARQ-ACK bit issued by the SPS PDSCH with the release DCI alone (e.g., the DCI issuing one SPS configuration) may be derived from the TDRA table row index indicated in the activation DCI and the offset K1 indicated in the release DCI. In some implementations, the location of the HARQ-ACK bit of the SPS PDSCH grant with the joint release DCI may be derived based on the TDRA table row index indicated in the activation DCI of the SPS PDSCH with the lowest SPS configuration index in the joint grant configuration and the offset K1 indicated in the release DCI.

In some implementations, if HARQ-ACKs for SPS configuration are reported using a type 2HARQ-ACK codebook, the HARQ-ACK bit order for SPS PDSCH release with individual/joint release DCI may be derived based on a Downlink Allocation Index (DAI) and an offset (e.g., K1) indicated in the release DCI. In some such implementations, the location of the HARQ-ACK bits within the HARQ-ACK codebook of the SPS PDSCH with associated PDCCH may be derived based on the DAI indicated in the activation DCI and an offset (e.g., K1). In some implementations, HARQ-ACK bits for SPS PDSCH without corresponding PDCCH may be appended after PDSCH for dynamic scheduling and/or HARQ-ACK bits for SPS PDSCH release. In some implementations, the HARQ-ACK bit order may be determined in terms of an ascending order of DL slots per { SPS configuration index, serving cell index }, an ascending order of SPS configuration index per { serving cell index }, and/or an ascending order of serving cell index.

In some implementations, the HARQ-ACK codebook for SPS HARQ-ACK bits when transmitted in PUCCH resources configured to transmit only SPS HARQ-ACK bits may also be referred to as a type 1HARQ-ACK codebook. The type 1HARQ-ACK codebook herein may also be referred to as a type 1HARQ-ACK codebook transmitted in PUCCH resources scheduled by DCI formats (e.g., DCI format 1_0, DCI format 1_1, DCI format 1_2).

In Rel-16, the UE may be configured with two HARQ-ACK codebooks. In some embodiments, if the pdsch-HARQ-ACK-codebook list is provided to the UE, the UE may be instructed to generate one or more HARQ-ACK codebooks (e.g., via the pdsch-HARQ-ACK-codebook list). In some implementations, if the UE is instructed to generate one HARQ-ACK codebook, the one HARQ-ACK codebook may be associated with PUCCH with priority index "0". In some implementations, if a pdsch-HARQ-ACK-codebook list is provided to the UE, the UE may multiplex the same HARQ-ACK codebook, with only HARQ-ACK information associated with the same priority index. In some implementations, if the UE is instructed to generate two HARQ-ACK codebooks, a first HARQ-ACK codebook may be associated with PUCCH with priority index "0" (e.g., low priority) and a second HARQ-ACK codebook may be associated with PUCCH with priority index "1" (e.g., high priority), the UE may provide { PUCCH-Config, UCI-OnPUSCH, PDSCH-codeblockgrouptransision } through { PUCCHConfigurationList, UCI-on pusch-List and PDSCH-codeblockgrouptransision } for each of the first HARQ-ACK codebook and the second HARQ-ACK codebook.

In some embodiments, various methods may be implemented to determine PUCCH resources for transmitting HARQ-ACK bits. In some implementations, if the UE sends an O including HARQ-ACK information bits _UCI UCI information bits, the UE mayThe PUCCH resource set is determined as one of the following four PUCCH resource sets: a first set of PUCCH resources with PUCCH-resource estid=0 and the following condition is satisfied: if O _UCI Less than or equal to 2 comprises 1 or 2 HARQ-ACK information bits, and when the transmission of the HARQ-ACK information and the SR simultaneously happens, positive or negative Scheduling Request (SR) on one SR transmission occasion is carried out; a second set of PUCCH resources with PUCCH-resource estid=1, satisfying the following condition: if provided by a higher layer, if 2<O _UCI ≤N ₂ And N2 is equal to maxpaylo ad size if maxpaalyloadsize is provided for PUCCH resource set of PUCCH-resource id=1, otherwise N ₂ Equal to 1706; a third set of PUCCH resources with PUCCH-resource estid=2, satisfying the following condition: if provided by a higher layer, if N ₂ <O _UCI ≤N ₃ And if maxPayloadSize is provided for PUCCH resource set for PUCCH-resource id=2, then N ₃ Equal to maxPayloadSize, otherwise N ₃ Equal to 1706; or a fourth set of PUCCH resources with PUCCH-resource estid=3, satisfying the following condition: if provided by a higher layer, if N ₃ <O _UCI ≤1706。

In some embodiments, if the UE is provided with AN SPS-PUCCH-AN-List and transmits AN O including only HARQ-ACK information bits in response to one or more SPS PDSCH receptions _UCI UCI information bits, the UE may determine the PUCCH resource to be one of the following four PUCCH resources: PUCCH resource with SPS-PUCCH-AN-resource id=0, satisfies the following condition if O _UCI 2 or less; PUCCH resource of SPS-PUCCH-AN-resource id=1, and the following condition is satisfied: if provided, if 2<O _UCI ≤N _1,SPS Wherein N is _1,SPs Provided by maxPayloadSize in SPS-PUCCH-AN-List for SPS-PUCCH-AN-resource id=1, or N _1,SPS Equal to 1706; PUCCH resources with SPS-PUCCH-AN-resource id=2, and the following condition is satisfied: if provided, if N _1,SPS <O _UCI ≤N _2,SPS Wherein N is _2,SPS Provided by maxPayloadSize in SPS-PUCCH-AN-List for SPS-PUCCH-AN-resource id=2, or N _2,SPS Equal to 1706; or PUCCH resource of SPS-PUCCH-AN-resource id=3And the following conditions are satisfied: if provided, if N _2,SPS <O _UCI ≤N _3,SPS Wherein N is _3,SPS Equal to 1706.

In Rel-15 and Rel-16, with respect to unpaired spectrum, PUCCH may not be transmitted when the subset of symbols containing scheduled or configured PUCCH transmissions are semi-static DL symbols or symbols containing Synchronization Signal Blocks (SSBs). In some implementations, 14 symbols may be in one or more slots, and the direction (e.g., uplink or downlink) of each of the 14 symbols may be configured by a slot configuration tdd-UL-DL-configuration common or tdd-UL semi-statically-DL-configuration determined. Fig. 1 is a schematic diagram of a typical 5G NR frame structure implemented according to an example of the present disclosure. For example, slot 100 may include 14 symbols (e.g., symbol 0 through symbol 13), each configured as one symbol (e.g., D, F, U) as shown in fig. 1. Symbols 0 through 5 may be configured with symbols indicated as Downlink (DL) symbols (e.g., D), symbols 6 and 7 may be configured with symbols indicated as flexible symbols (e.g., F), and symbols 8 through 13 may be configured with symbols indicated as Uplink (UL) symbols (e.g., U). If PUCCH transmission is configured (e.g., patterned with diagonal lines) in symbols 4 to 13 as shown in fig. 1, PUCCH may not be transmitted because PUCCH is included in DL symbols (e.g., D), at least because symbol 4 and symbol 5 may be preconfigured with DL symbols (e.g., D). In other words, the PUCCH may collide with a DL symbol (e.g., D) at least in symbol 4 and symbol 5.

As described above, the present disclosure provides a UE and a method for managing the behavior of the UE for HARQ-ACK transmissions associated with SPS PDSCH, which may include delaying SPS HARQ-ACK feedback, constructing HARQ-ACK codebooks, and/or multiplexing PUCCHs for SPS HARQ-ACKs and other PUCCHs or PUSCHs.

In some embodiments, delaying SPS HARQ-ACK bits to be transmitted in any slot after the slot for the PUCCH resource for SPS HARQ-ACK is initially configured may be advantageous for rescheduling SPS PDSCH that was not successfully received/decoded. In some implementations, the UE may configure and/or indicate PUCCH resources for SPS HARQ-ACK bits for transmission delay.

In some embodiments of the present disclosure, PUCCH resources may be provided to a UE for transmitting delayed HARQ-ACK bits corresponding to SPS PDSCH reception. In some implementations, if the UE is provided with a subslotLength-ForPUCCH, the slot may include a sub-slot, which may indicate the number of symbols of the sub-slot for the associated PUCCH transmission. To provide additional transmission opportunities, for example, HARQ-ACK bits received corresponding to SPS PDSCH configured in slot "n", PUCCH resources in slot "n+k+d" may be provided. The offset "k" may be the number of slots indicated by the PDSCH-to-harq_feedback timing indicator field in the corresponding DCI format of the SPS configuration for activating SPS PDSCH reception, or provided by 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 implementations. In some such implementations, when the offset "d" =0, the SPS HARQ-ACK bit may be considered to be a non-delayed SPS HARQ-ACK bit.

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

Fig. 2 is a schematic diagram of a delayed HARQ-ACK transmission based on a PUCCH corresponding to an SPS PDSCH, according to an example implementation of the present disclosure. In some implementations, example slots are shown in fig. 2, which may include slot 202A (e.g., slot 0), slot 202B (e.g., slot 1), slot 202C (e.g., slot 2), slot 202D (e.g., slot 3), and slot 202E (e.g., slot 4). Slots 202A, 202B, and 202C may each be configured with one or more DL symbols (e.g., causing them to become non-patterned slots), while slots 202D and 202E may each be configured with one or more UL symbols (e.g., causing them to become patterned slots). SPS PDSCH 204 may be transmitted in slot 202A (e.g., slot "n"), and PUCCH 206A for HARQ-ACK corresponding to SPS PDSCH 204 may be configured in slot 202B based on offset k=1. However, in some implementations, PUCCH 206A configured in slot 202B may not be transmitted to the base station, e.g., because PUCCH 206A collides with DL symbols in slot 202B (e.g., PUCCH 206A configured in a non-slot patterns slot 202B or slot 202B with DL symbols).

In some such implementations, when PUCCH 206A is not transmittable in slot 202B (e.g., when PUCCH collides with one or more DL symbols in slot 202B), the UE may first determine whether a particular parameter (e.g., it is also included in the SPS configuration) indicates a delay in the corresponding HARQ transmission (e.g., when a particular bit representing the parameter is set to 1). When a particular parameter indicates a delay of HARQ transmission, the UE may determine to configure another PUCCH 206B (e.g., corresponding to the same SPS PDSCH 204) in slot 202D for transmission of HARQ-ACK based on offset k=1 and another offset d=2. In some implementations, the UE may determine the offset D and may then identify the slot 202D because this slot is the earliest (in the time domain) between the slot 202B and the largest slot (e.g., slot 202E) that includes a sufficient number of uplink (and/or flexible) symbols for carrying the PUCCH 206B.

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

In some embodiments of the present disclosure, when the HARQ-ACK bits corresponding to (e.g., the first) SPS PDSCH are delayed (e.g., indicated by different HARQ-ACK parameters included in the SPS configuration), there may be other HARQ-ACK bits corresponding to another (e.g., the second) SPS PDSCH configured in the same time slot. In some such implementations, other HARQ-ACK bits of other SPS PDSCH corresponding to the same or different SPS configuration may be non-delayed HARQ-ACK bits. An example of such an implementation is shown in fig. 3. Fig. 3 is a diagram of PUCCH delayed HARQ-ACK transmissions corresponding to multiple SPS PDSCH of one or more SPS configurations.

In some implementations, example slots as shown in fig. 3 may include slot 302A (e.g., slot 0), slot 302B (e.g., slot 1), slot 302C (e.g., slot 2), slot 302D (e.g., slot 3), and slot 302E (e.g., slot 4). Slots 302A, 302B, and 302C may each be configured with one or more DL symbols (e.g., resulting in them becoming non-patterned slots), while slots 302D and 302E may each be configured with one or more UL symbols (e.g., resulting in them becoming patterned slots). The first SPS PDSCH 304A of SPS configuration 1 may be transmitted in the slot 302A and the PUCCH of the HARQ-ACK corresponding to the first SPS PDSCH 304A of SPS configuration 1 may be delayed to the slot 302D based on the offset k2=1 and another offset d1=2. In other words, the HARQ-ACK bits of the first SPS PDSCH 304A corresponding to SPS configuration 1 in the slot 302A may be delayed to the slot 302D based on the offset k2=1 and the offset d1=2. The second SPS PDSCH 304B of SPS configuration 2 may be transmitted in slot 302B and, based on the offset k2=2 and the offset d1=0, the PUCCH of the HARQ-ACK corresponding to the second SPS PDSCH 304B of SPS configuration 2 may be configured in the same slot 302D. In other words, according to the offset k2=2 and the offset d1=0, the HARQ-ACK bit of the second SPS PDSCH 304B corresponding to SPS configuration 2 in the slot 302B may be indicated as being transmitted by the PDSCH-to-harq_feedback field in the corresponding active DCI 2 slots (e.g., in the same slot 302D) after the second SPS PDSCH 304B.

Thus, delayed HARQ-ACK bits for the first SPS PDSCH 304A of SPS configuration 1 and non-delayed HARQ-ACK bits for the second SPS PDSCH 304B of SPS configuration 2 may be allocated to the same time slot 302D. In some implementations, the UE may determine to transmit delayed HARQ-ACK bits for the first SPS PDSCH 304A corresponding to SPS configuration 1 and non-delayed HARQ-ACK bits for the second SPS PDSCH 304B corresponding to SPS configuration 2 in the same slot 302D of a new PUCCH (e.g., PUCCH 306) corresponding to the first SPS PDSCH 304A and the second SPS PDSCH 304B. In some such implementations, the UE may determine whether to transmit delayed HARQ-ACK bits and non-delayed HARQ-ACK bits on the third PUCCH 306 based on the payload sizes of the delayed HARQ-ACK and non-delayed HARQ-ACK.

In some implementations, the new PUCCH resource (e.g., the third PUCCH 306) in the slot 302D may be determined based on the total payload size of the delayed HARQ-ACK bits and the non-delayed HARQ-ACK bits. In some implementations, when the total payload size is below a threshold number of bits (e.g., 2 bits), the PUCCH resource may be a PUCCH resource with SPS-PUCCH-AN-resource id=0 configured in SPS-PUCCH-AN-List, where. In some implementations, when the total payload size is greater than the threshold number of bits and less than the second threshold number of bits, the PUCCH resource may be a PUCCH resource with SPS-PUCCH-AN-resource id=1 configured in AN SPS-PUCCH-AN-List. In some implementations, when the total payload size is greater than the second threshold number of bits and less than the third threshold number of bits, the PUCCH resource may be a PUCCH resource with SPS-PUCCH-AN-resource id=2 configured in AN SPS-PUCCH-AN-List. In some implementations, when the total payload size is greater than the third threshold number of bits and less than the fourth threshold number of bits, e.g., 1706 bits, the PUCCH resource may be a PUCCH resource with SPS-PUCCH-AN-resource id=3 configured in SPS-PUCCH-AN-List. Note that SPS-PUCCH-AN-List may or may not configure PUCCH resources of SPS-PUCCH-AN-resource eid=1, SPS-PUCCH-AN-resource eid=2, and SPS-PUCCH-AN-resource eid=3. In some such implementations, if the total load size exceeds a maximum allowed size (e.g., above a threshold number of bits), the BS may configure the appropriate SPS configuration and PUCCH resources such that PUCCH resources capable of accommodating delayed HARQ-ACKs and non-delayed HARQ-ACKs may always be available for the UE to transmit delayed HARQ-ACKs and non-delayed HARQ-ACKs.

As described 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 implementations, the maximum value in the set of values may be pre-configured or predefined, and the set of values may include all integers less than or equal to the maximum value. An example of such an implementation may be shown in fig. 4. Referring to fig. 4, a schematic diagram of PUCCH delayed HARQ-ACK transmission based on SPS PDSCH according to another embodiment of the present invention is shown. In some implementations, example slots as shown may include slot 402A (e.g., slot 0), slot 402B (e.g., slot 1), slot 402C (e.g., slot 2), slot 402D (e.g., slot 3), and slot 402E (e.g., slot 4). Slots 402A, 402B, and 402C may each be configured with one or more DL symbols (e.g., causing them to become non-patterned slots), while slots 402D and 402E may each be configured with one or more UL symbols (e.g., causing them to become patterned slots). In some implementations, the offset "d" may be one value in the set of values {0, 1, 2, 3 }. SPS PDSCH 404 may be transmitted in slot 402A and PUCCH (e.g., 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 implementations, the first PUCCH 406A in the slot 402B may not be transmitted to the base station, for example, because the first PUCCH 406A collides with DL symbols in the slot 402B (e.g., in the non-patterned slot 402B or the slot 402B with DL symbols).

Thus, based on offset k=1 and the other offset d=1, the ue may not transmit HARQ-ACKs on the first PUCCH 406A in the slot 402B and may determine to transmit HARQ-ACKs 402C on the other PUCCH 406B (e.g., the second PUCCH) in the slot. Further, in some implementations, the second PUCCH 406B in slot 402C may also collide with DL symbols in slot 402C (e.g., the second PUCCH 406B configured in the non-patterned slot 402C or the slot 402C with DL symbols). In some implementations, the UE may iteratively check for subsequent slots until the UE reaches a 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 for HARQ-ACK corresponding to SPS PDSCH 404 collides with a DL symbol in slot 402B, the UE may iteratively check for a subsequent slot until the next available slot with UL symbol or flexible symbol (e.g., slot 402D) is reached, or until the UE reaches a threshold of the number of check iterations (e.g., the UE may be configured with a threshold number of two check iterations, which may allow the UE to check only two subsequent slots with UL symbols or flexible symbols after slot 402B). Thus, the UE may further determine not to transmit HARQ-ACKs on the second PUCCH 406B in slot 402C and determine to transmit HARQ-ACKs on the third PUCCH 406C in slot 402D because the third PUCCH 406C may not collide with UL symbols based on offset k=1 and another offset d=2 (e.g., the third PUCCH 406C would be transmitted in the patterned slot 402D or the slot 402D has UL symbols).

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

In some implementations, the offset "d" may be a value determined based on the slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration com and PUCCH resource related configurations (e.g., PUCCH-Config and SPS-Config or SPS-PUCCH-AN-List-r 16).

In some embodiments, when only one SPS configuration is configured, or when only one SPS configuration is configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a minimum value such that a symbol containing PUCCH resources indicated in the slot "n+k+d" by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH-configuration may be indicated as uplink by the slot configuration tdd-UL-DL-configuration de-ded or tdd-UL-DL-configuration command. In some implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception, as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception.

In some embodiments, when multiple SPS configurations are configured or are configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a minimum value such that a symbol containing PUCCH resources indicated in slot "n+k+d" by SPS-PUCCH-AN-r16 in PUCCH-configuration may be indicated as uplink by slot configuration tdd-UL-DL-configuration de-configured or tdd-UL-DL-configuration command. In some implementations, SPS-PUCCH-AN-r16 may indicate the PUCCH resource, which may accommodate delayed (or non-delayed) HARQ-ACK bits corresponding to SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a minimum value such that a symbol containing PUCCH resources indicated in the slot "n+k+d" by the SPS-PUCCH-AN in the n1PUCCH-AN in the SPS-Config or the SPS-PUCCH-AN-r16 in the PUCCH-Config may be indicated as AN uplink symbol or a flexible symbol by the slot configuration tdd-UL-DL-configuration de-ded or tdd-UL-DL-configuration command. In some implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception.

In some embodiments, when there are multiple SPS configurations configured or there are multiple SPS configurations configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a minimum value such that a symbol containing PUCCH resources indicated in the slot "n+k+d" by SPS-PUCCH-AN-r16 in PUCCH-configuration may be indicated as AN uplink symbol or a flexible symbol by the slot configuration tdd-UL-DL-configuration de-ded or tdd-UL-DL-configuration command. In some implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol containing PUCCH resources indicated in slot "n+k+d" by SPS-PUCCH-AN-n 16 in SPS-Config or by SPS-PUCCH-AN-n 16 in PUCCH-Config may be indicated as AN uplink symbol or a flexible symbol by a slot configuration tdd-UL-DL-configuration de-divided or tdd-UL-DL-configuration command. In some implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated in the slot "n+k+d" by either n1PUCCH-AN in SPS-configuration or SPS-PUCCH-AN-r16 in PUCCH-configuration may be indicated as uplink by the slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration common. In some such implementations, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot that follows the first slot may be set to NACK.

In some embodiments, when multiple SPS configurations or configurations are configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol containing PUCCH resources indicated in slot "n+k+d" by SPS-PUCCH-AN-r16 in PUCCH-Config is indicated as AN uplink symbol or a flexible symbol by slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration command. In some such implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated in slot "n+k+d" by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as uplink by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common. In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot subsequent to the first slot may be set to NACK. In some such implementations, the HARQ-ACK bits in the second slot may be considered delayed HARQ-ACK bits.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol, which contains one or more PUCCH resources among PUCCH resources indicated by n1PUCCH-AN in SPS-Config or SPS-PUCCH-AN-r16 in PUCCH resource set and PUCCH resources overlapping with the PUCCH resources indicated by n1PUCCH-AN in SPS-Config or PUCCH-AN-r16 in SPS-Config, is indicated by slot configuration tdd-UL-DL-configuration-dedicated or tdd-UL-DL-configuration command in slot "n+k+d", may be dynamically scheduled and may accommodate AN SPS HARQ-ACK codebook. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by n1PUCCH-AN in SPS-Config or by SPS-PUCCH-AN-r16 in PUCCH may be indicated as upstream or flexible by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common in slot "n+k+d". In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot located after the first slot may be set to NACK.

In some embodiments, when there are multiple SPS configurations configured or there are multiple SPS configurations configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol, which is indicated as uplink or flexible by the slot configuration tdd-UL-DL-configuration decoded or tdd-UL-DL-configuration command in slot "n+k+d", is included in one or more of PUCCH resources in the PUCCH resource set indicated by SPS-PUCCH-AN-r16 in PUCCH-Config and PUCCH resources overlapping with PUCCH resources indicated by SPS-PUCCH-AN-r16 in the PUCCH-Config, may be dynamically scheduled and may accommodate AN SPS HARQ-ACK codebook. In some implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as upstream or flexible by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common in slot "n+k+d". In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot located after the first slot may be set to NACK.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol, which contains one or more PUCCH resources among PUCCH resources indicated by n1PUCCH-AN in SPS-Config or SPS-PUCCH-AN-r16 in PUCCH resource set and PUCCH resources overlapping with the PUCCH resources indicated by n1PUCCH-AN in SPS-Config or PUCCH-AN-r16 in SPS-Config, is indicated by slot configuration tdd-UL-DL-configuration-dedicated or tdd-UL-DL-configuration command in slot "n+k+d", may be dynamically scheduled and may accommodate AN SPS HARQ-ACK codebook. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH-configuration may be indicated as upstream by a slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration command in slot "n+k+d". In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot located after the first slot may be set to NACK.

In some embodiments, when multiple SPS configurations are configured or multiple SPS configurations are configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that a symbol, which contains one or more of PUCCH resources indicated by SPS-PUCCH-AN-n-r 16 in PUCCH-Config and PUCCH resources overlapping with PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config, is indicated as uplink or flexible by slot configuration tdd-UL-DL-configuration-scheduled or tdd-UL-DL-configuration command in slot "n+k+d", may be dynamically scheduled and may accommodate AN SPS-ACK codebook. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as upstream by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common in slot "n+k+d". In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot located after the first slot may be set to NACK.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that symbols in time slot "n+k+d" are indicated as uplink or flexible by time slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration command, the symbols contain PUCCH resources indicated by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH resource set and PUCCH resources in PUCCH resource set overlapping with SPS-PUCCH resources in n1PUCCH-AN in PUCCH-configuration or PUCCH-AN-r16, and SPS resources in SPS-configuration can be accommodated as SPS resources in PUCCH-PUCCH or PUCCH in PUCCH-PUCCH and the HARQ priority can be accommodated as a plurality of SPS-resources in PUCCH, and the same HARQ-PUCCH resource set can be received as the SPS-PUCCH resources in the PUCCH. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by n1PUCCH-AN in SPS-Config or by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as upstream or flexible by slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration common in slot "n+k+d". In some embodiments, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, HARQ-ACK bits corresponding to SPS PDSCH reception in a second PUCCH provided for HARQ-ACK bits in a second slot located after the first slot may be set to NACK.

In some embodiments, when multiple SPS configurations are configured or multiple SPS configurations are configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that symbols in slot "n+k+d" are indicated as uplink or flexible by slot configuration tdd-UL-DL-configuration de-allocated or tdd-UL-configuration command, the symbols contain PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-configuration in a set of PUCCH resources and PUCCH resources in a set of PUCCH resources overlapping with the PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-configuration, and PUCCH resources in a set of PUCCH resources overlapping with the PUCCH resources indicated by SPS-AN-r 16 in PUCCH-configuration may be configured as priority as indicated by the HARQ-codebook id in PDSCH received SPS-configuration, and one or more of the PUCCH resources may be accommodated and the PUCCH resources may be encoded with the same SPS-ACK code. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by n1PUCCH-AN in SPS-Config or by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as upstream or flexible by slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration common in slot "n+k+d".

In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception.

In some embodiments, when there are multiple SPS configurations configured or there are multiple SPS configurations configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that symbols in slot "n+k+d" are indicated as uplink or flexible by slot configuration tdd-UL-DL-configuration de-allocated or tdd-UL-configuration command, the symbols contain PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-configuration in a set of PUCCH resources and PUCCH resources in a set of PUCCH resources overlapping with the PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-configuration, and PUCCH resources in a set of PUCCH resources overlapping with the PUCCH resources indicated by SPS-AN-r 16 in PUCCH-configuration may be configured as priority as indicated by the HARQ-codebook id in PDSCH received SPS-configuration, and one or more of the PUCCH resources may be accommodated and the PUCCH resources may be coded as a set of SPS-HARQ resources. In some implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate HARQ-ACK bits corresponding to delayed (or non-delayed) SPS PDSCH reception as well as other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config may be indicated as upstream by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common in slot "n+k+d".

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), "d" is a set of values such that symbols containing one or more of the PUCCH resources indicated by n1PUCCH-AN in SPS-Config or by SPS-PUCCH-AN-r16 in PUCCH-Config and symbols of the PUCCH resources in the PUCCH resource set may be dynamically scheduled and SPS HARQ-ACK codebooks may be accommodated in time slots "n+k+d", the symbols of these PUCCH resources being indicated as uplink symbols or flexible symbols by the time slot configuration tdd-UL-DL-configuration de-allocation or tdd-UL-DL-configuration command. In some such implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate delayed (or non-delayed) HARQ-ACK bits corresponding to SPS PDSCH reception and other delayed and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols of the PUCCH resources indicated by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH-configuration contained in the slot "n+k+d" may be indicated as uplink symbols or flexible symbols by the slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration common. In some such implementations, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, SPS PDSCH reception corresponding HARQ-ACK bits in a second PUCCH provided for HARQ-ACK bits in a second slot that follows the first slot may be set to NACK.

In some embodiments, when there are multiple SPS configurations configured or there are multiple SPS configurations configured and activated, and when the UE is not configured to monitor DCI (e.g., DCI format 2_0), the offset "d" may be a set of values such that symbols containing one or more of the PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config and symbols of the PUCCH resources in the PUCCH resource set may be dynamically scheduled and SPS HARQ-ACK codebook may be accommodated in time slot "n+k+d", the symbols of these PUCCH resources being indicated as uplink symbols or flexible symbols by the time slot configuration tdd-UL-DL-configuration determined or tdd-UL-DL-configuration command. In some such implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate delayed (or non-delayed) HARQ-ACK bits corresponding to SPS PDSCH reception and other delayed HARQ-ACK bits and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config in slot "n+k+d" are indicated as uplink symbols or flexible symbols by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common. If the HARQ-ACK bit corresponding to SPS PDSCH reception is reported in the first PUCCH provided for the HARQ-ACK bit in the first slot, the corresponding HARQ-ACK bit may be set to NACK in the second PUCCH provided for the HARQ-ACK bit in the second slot located after the first slot. In some such implementations, the HARQ-ACK bits in the second slot may be considered delayed HARQ-ACK bits.

In some embodiments, when only one SPS configuration is configured or only one SPS configuration is configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), "d" is a set of values such that symbols containing one or more of the PUCCH resources indicated by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH-configuration and symbols of PUCCH resources in the PUCCH resource set may be dynamically scheduled and SPS HARQ-ACK codebook may be accommodated in slot "n+k+d", the symbols of these PUCCH resources being indicated as uplink symbols or flexible symbols by slot configuration tdd-UL-DL-configuration de-or tdul-DL-configuration command. In some such implementations, SPS-PUCCH-AN-r16 may indicate a PUCCH resource that may accommodate delayed (or non-delayed) HARQ-ACK bits corresponding to SPS PDSCH reception and other delayed HARQ-ACK bits and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols of the PUCCH resources indicated by n1PUCCH-AN in SPS-configuration or by SPS-PUCCH-AN-r16 in PUCCH-configuration contained in the slot "n+k+d" may be indicated as uplink by the slot configuration tdd-UL-DL-configuration defined or tdd-UL-DL-configuration command. In some such implementations, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, SPS PDSCH reception corresponding HARQ-ACK bits in a second PUCCH provided for HARQ-ACK bits in a second slot that follows the first slot may be set to NACK.

In some embodiments, when more than one SPS configuration is configured or more than one SPS configuration is configured and activated, and when the UE is configured to monitor DCI (e.g., DCI format 2_0), d is a set of values such that symbols containing one or more of the PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config and symbols of PUCCH resources in the PUCCH resource set may be dynamically scheduled and SPS HARQ-ACK codebooks may be accommodated in time slots "n+k+d", the symbols of these PUCCH resources being indicated as uplink symbols or flexible symbols by the time slot configuration tdd-UL-DL-configuration de-transmitted or tdd-DL-configuration command. In some such implementations, SPS-PUCCH-AN-r16 may indicate PUCCH resources that may accommodate delayed (or non-delayed) HARQ-ACK bits corresponding to SPS PDSCH reception and other delayed HARQ-ACK bits and non-delayed HARQ-ACK bits corresponding to other SPS PDSCH reception. In some such implementations, the maximum value of the offset "d" may be a value such that all symbols containing PUCCH resources indicated by SPS-PUCCH-AN-r16 in PUCCH-Config in slot "n+k+d" are indicated as uplink by slot configuration tdd-UL-DL-configuration dedicated or tdd-UL-DL-configuration common. In some such implementations, if HARQ-ACK bits corresponding to SPS PDSCH reception are reported in a first PUCCH provided for HARQ-ACK bits in a first slot, SPS PDSCH reception corresponding HARQ-ACK bits in a second PUCCH provided for HARQ-ACK bits in a second slot that follows the first slot may be set to NACK. In some such implementations, the HARQ-ACK bits in the second slot may be considered delayed HARQ-ACK bits.

In some embodiments, if the HARQ-codebook id in SPS-Config received by SPS PDSCH indicates a low priority HARQ-ACK codebook and a high priority HARQ-ACK codebook, respectively, the maximum value of offset "d" may be limited such that the value of "k+d" may be less than or equal to the maximum offset "K1" value in dl-DataToUL-ACKs in the first PUCCH-Config and the second PUCCH-Config. In some implementations, the above feature may apply when the type of HARQ-ACK codebook with the same priority as indicated by the HARQ-codebook id in SPS-Config received by SPS PDSCH is a type 1HARQ-ACK codebook, where the type of HARQ-ACK is configured by PDSCH-HARQ-ACK-codebook list-r 16. In some implementations, when the type of HARQ-ACK codebook with the same priority as indicated by the HARQ-codebook id in SPS-Config received by SPS PDSCH is a type 1HARQ-ACK codebook or a type 2HARQ-ACK codebook, the type of HARQ-ACK is configured by PDSCH-HARQ-ACK-codebook list-r 16.

In some implementations, all symbols may be determined as flexible symbols or uplink symbols when the slot configuration tdd-UL-DL-configuration de-configured and tdd-UL-DL-configuration common are not configured.

In some implementations, if the HARQ-Codebook ID in SPS-Config indicates a priority, then a sub-slot may be used instead of a slot for transmitting HARQ-ACK bits received by SPS PDSCH of SPS configuration, the priority corresponding to which is configured with subslotLengthForPUCCH-r16. In some implementations, the first PUCCH-Config may correspond to a low priority and the second PUCCH-Config may correspond to a high priority.

In some implementations, whether the HARQ-ACK may be delayed, may be configured or indicated by RRC configuration and/or by SPS configuration using an active DCI.

In some implementations, PUCCH resources provided for SPS HARQ-ACK transmissions may be determined based on the payload sizes of delayed and non-delayed HARQ-ACK bits.

In some implementations, PUCCH resources provided for SPS HARQ-ACK transmission may be determined based on the payload size of non-delayed HARQ-ACK bits.

Fig. 5 is a flow chart of a method/process for transmitting HARQ-ACKs by a UE, according to an example implementation of the present disclosure. As shown in fig. 5, process 500 may begin with receiving a semi-persistent scheduling (SPS) configuration in act 502. In some implementations, 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 a Downlink Control Information (DCI) format indicating activation of the SPS configuration in act 504. In some such implementations, the DCI format may further indicate a first offset (e.g., offset k) for transmitting the HARQ-ACK. In act 506, process 500 may also receive an SPS Physical Downlink Shared Channel (PDSCH) associated with the SPS configuration in a first time slot (e.g., time slot n).

After receiving the DCI format indicating the first offset, process 500 may identify a second slot (e.g., slot n+k) based on the first slot (e.g., slot n) and an offset (e.g., k) for transmitting the HARQ-ACK on a first Physical Uplink Control Channel (PUCCH) corresponding to the SPS PDSCH in act 508. After identifying the second slot for transmitting the HARQ-ACK on the first PUCCH, the process may determine whether the first PUCCH is contained within one or more symbols in the second slot, the one or more symbols being uplink symbols or flexible symbols in act 510. In some implementations, when the first PUCCH is determined to be included 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 within one or more symbols, process 500 may proceed to act 512, which may further determine whether the particular parameter included in the SPS configuration indicates a delayed HARQ transmission.

If it is determined that the particular parameter included in the SPS configuration indicates a HARQ transmission without delay (e.g., the bit representing the parameter is set to zero), process 500 may proceed to act 518, described below. On the other hand, when it is determined that the particular parameter included in the SPS configuration indicates a delayed HARQ transmission (e.g., the bit representing the parameter is set to 1), process 500 may identify a third slot (e.g., slot n+k+d) in act 514 based on the first slot and a second offset (e.g., offset d) for transmitting the HARQ-ACK on a second PUCCH corresponding to the SPS PDSCH.

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

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

In some embodiments, as described above, when process 500 reaches act 510 and it is determined that the first PUCCH is not included within 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 a delayed HARQ transmission. If it is determined that the particular parameters included in the SPS configuration do not indicate a delayed HARQ transmission, process 500 may proceed to act 518, where the UE may discard the HARQ-ACK.

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

Fig. 6 is a flow chart further illustrating the method/process of fig. 5, implemented according to an example of the present disclosure. In some embodiments, after identifying the third slot for transmitting the HARQ-ACK on the second PUCCH corresponding to the SPS PDSCH, act 514 is shown in fig. 5. Process 500 may proceed to act 602 (e.g., rather than 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 a second DCI format in act 604 that activates the second SPS configuration. In some embodiments, the second DCI format may further indicate a third offset for transmitting the second HARQ-ACK. In act 606, process 500 may also receive a second SPS PDSCH associated with the second SPS configuration in a fourth time slot.

In some embodiments, when the third slot identified for transmitting HARQ-ACKs in act 514 is also identified for transmitting second HARQ-ACKs based on the fourth slot and the third offset (e.g., the third slot identified for transmitting HARQ-ACKs in act 514 is the same slot as the slot configured for transmitting second HARQ-ACKs), process 500 may transmit HARQ-ACKs (e.g., in act 514) and second HARQ-ACKs (e.g., in act 604) on a third PUCCH corresponding to SPS PDSCH and second SPS PDSCH in the third slot instead of proceeding to act 516, the ue may transmit only HARQ-ACKs on the second PUCCH in the third slot in act 516. 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. In particular, defining the size of the HARQ-ACK codebook for PUCCH resources for transmitting only SPS HARQ-ACK bits and ordering of SPS HARQ-ACK bits may be necessary to construct the HARQ-ACK codebook. Constructing HARQ-ACK codebook for PUCCH resources provided to UE Reporting only SPS HARQ-ACK bits may be implemented by some examples. For example, the example pseudocode "m-n.ltoreq.k+d _max "may be used to construct a HARQ-ACK codebook for PUCCH resources of a UE in UL slot" m "to report only SPS HARQ-ACK bits. HARQ-ACK information received by the SPS PDSCH in the DL slot overlapping with UL slot "n" may be multiplexed in PUCCH resources in UL slot "m". In some implementations, the offset "k" may be the number of UL slots indicated by the PDSCH-to-harq_feedback timing indicator field configured in the corresponding DCI format by SPS for activating SPS PDSCH reception, or the offset "d" provided by dl-DataToUL-ACK if there is no PDSCH-to-harq_feedback timing indicator field in the DCI format _max "may be the maximum UL slot number of HARQ-ACK information that may be received by the delayed SPS PDSCH. In some implementations, HARQ-ACK codebook construction may start with the earliest DL slot in serving cell "c" configuring SPS PDSCH reception (e.g., may correspond to "n _D =0), and the corresponding HARQ-ACK information may be multiplexed in the PUCCH resource.

In some embodiments, the delayed HARQ-ACK bits for { SPS configuration index, serving cell index } may be appended after or before the non-delayed HARQ-ACK bits for { SPS configuration index, serving cell index }. In some embodiments, the bit ordering of the delayed HARQ-ACK bits may be an ascending order of DL slots for each { SPS configuration index, serving cell index } followed by an ascending order of SPS configuration index for each { serving cell index } followed by an ascending order of serving cell index.

In some implementations, for all { DL slots, SPS configuration index, serving cell index } delayed HARQ-ACK bits, all { DL slots, SPS configuration index, serving cell index } delayed HARQ-ACK bits may be appended after or before non-delayed HARQ-ACK bits.

In some embodiments, the delayed HARQ-ACK bit of the serving cell may be appended after or before the non-delayed HARQ-ACK bit of the serving cell. In some embodiments, the bit ordering of the delayed HARQ-ACK bits may be an ascending order of DL slots per { SPS configuration index, serving cell index } followed by an ascending order of SPS configuration index per { serving cell index }. In some implementations, the bit ordering of the non-delayed HARQ-ACK bits may be an ascending order of DL slots per { SPS configuration index, serving cell index } followed by an ascending order of SPS configuration index per { serving cell index }.

In some embodiments, discarding of some delayed SPS HARQ-ACK bits may be performed when the total payload size of delayed and non-delayed SPS HARQ-ACK bits exceeds the maxPayloadSize of the PUCCH resources provided for SPS HARQ-ACK bits or where the dynamically scheduled PUCCH resources SPS HARQ-ACK bits are multiplexed or may result in a code rate of the total number of HARQ-ACK bits being higher than the maximum code rate of the PUCCH resources.

In some embodiments, when the total payload size of delayed and non-delayed SPS HARQ-ACK bits exceeds the maxPayloadSize of the PUCCH resource provided for SPS HARQ-ACK bits, the PUCCH resource is based on the total payload size of non-delayed SPS HARQ-ACK bits, some dropping of the delayed SPS HARQ-ACK bits may be performed.

In some embodiments, the dropping of the delayed SPS HARQ-ACK bits may be arranged in ascending order of DL slot number for each { SPS configuration index, serving cell index } received by the corresponding SPS PDSCH, and/or in descending order of SPS configuration index for each serving cell index, and/or in descending order of serving cell index.

As described above, the present disclosure may provide management of UE behavior for HARQ-ACK transmission of SPS PDSCH by multiplexing PUCCH only for SPS HARQ-ACK and other PUCCHs or PUSCHs.

In some implementations, when PUCCH resources used only for transmitting SPS HARQ-ACK bits overlap with other PUCCHs or PUSCHs, a manner/mechanism of defining UCI to multiplex SPS HARQ-ACK bits and the overlapping PUCCHs may be required.

In some implementations, when PUCCH resources are used for SPS HARQ-ACK transmission only, and symbols containing PUCCH resources are indicated as uplink symbols or flexible symbols by slot configuration tdd-UL-DL-configuration command or tdd-UL-DL-configuration de-tected, the PUCCH resources are contained in resource set "Q" for a group of PUCCH resources with the same priority indicated by HARQ-codebook id in SPS-configuration received by SPS PDSCH corresponding to SPS HARQ-ACK bits. In some implementations, the UCI multiplexing procedure may be performed as specified in clause 9.2.5 in TS 38.213V15.3.0.

In some implementations, for serving cell c, when the UCI multiplexing procedure results in SPS HARQ-ACK bits being multiplexed in dynamically scheduled PUCCH resources for transmission of the HARQ-ACK codebook, and if the HARQ-ACK codebook is a type 1HARQ-ACK codebook, if specified in clause 9.1.2.1 of TS 38.213V15.3.0, the SPS PDSCH corresponding to the SPS HARQ-ACK bits receives M received at candidate PDSCH corresponding to HARQ-ACK bits of the type 1HARQ-ACK codebook _A,c Within an opportunity, SPS HARQ-ACK bits may be reported in the HARQ-ACK bits of the type 1HARQ-ACK codebook. In some implementations, if SPS PDSCH reception corresponding to SPS HARQ-ACK bits is not M of candidate PDSCH reception corresponding to HARQ-ACK bits of the type 1HARQ-ACK codebook _A,c During the opportunity, SPS HARQ-ACK bits may not be reported in the HARQ-ACK bits of the type 1HARQ-ACK codebook.

In some implementations, if there is an SPS containing delayed SPS HARQ-ACK bits that may be multiplexed in PUCCH resourcesHARQ-ACK bits, the type 1HARQ-ACK codebook in the dynamically scheduled PUCCH resource may be extended, and the number of delay slots "d" may result in "k+d" being greater than the maximum value of the offset "k". In some implementations, "k" may be the number of slots indicated by a PDSCH-to-harq_feedback timing indicator field in the corresponding DCI format for an SPS configuration for activating SPS PDSCH reception, or provided by dl-DataToUL-ACK if a PDSCH-to-harq_feedback timing indicator field is not present in the DCI format. In some implementations, the maximum value of "k" is the maximum value configured in dl-DataToUL-ACK. In some implementations, an additional number of HARQ-ACK bits may be added or appended to the type 1HARQ-ACK codebook, the number of HARQ-ACK bits may be the number of occasions of candidate PDSCH reception in a slot where there is a corresponding SPS PDSCH reception for the delayed SPS HARQ-ACK bits, and SPS PDSCH reception may not be M of candidate PDSCH reception corresponding to HARQ-ACK bits of the type 1HARQ-ACK codebook _A,c Within a single occasion.

In some embodiments, a type 1HARQ-ACK codebook may be extended for candidate PDSCH reception in multiple slots, which may be preconfigured or predefined. In some embodiments, the extended number of slots is in DL slots. For example, when the most delayed UL slot results in "k+d" being greater than the maximum value of "k" by "X" UL slots, the number of extensions of DL slots may be equal to or less than

And each time slot. In some implementations, the parameters PDSCH-codeblockgrouptransmsision and/or maxnrofcodewordsschedule bydci may be considered not configured to determine the number of HARQ-ACK bits for the extended number of DL slots.

In some implementations, when the UCI multiplexing process results in SPS HARQ-ACK bits being multiplexed in dynamically scheduled PUCCH resources to transmit the HARQ-ACK codebook, and if the HARQ-ACK codebook is a type 2HARQ-ACK codebook, the SPS HARQ-ACK bits may be reported by appending the SPS HARQ-ACK bits to the type 2HARQ-ACK codebook.

In some implementations, when SPS HARQ-ACK bits are multiplexed in a type 1HARQ-ACK codebook or a type 2HARQ-ACK codebook of a dynamically scheduled PUCCH, and the PUCCH overlaps a PUSCH in a slot, the SPS HARQ-ACK bits may be multiplexed in a PUSCH in the slot. When SPS HARQ-ACK bits are not multiplexed in the type 1HARQ-ACK codebook or the type 2HARQ-ACK codebook of the dynamically scheduled PUCCH in a slot, and the PUCCH configured to transmit only SPS HARQ-ACK bits overlaps with the PUSCH in the slot, SPS HARQ-ACK bits may be multiplexed in the PUSCH in the slot.
