Simultaneous transmission of delayed SPS HARQ feedback with current PUCCH

Abstract

Methods and apparatuses for delaying transmission of HARQ-ACK feedback overlapping with DL symbols. The apparatus determines to transmit PUCCH SPS HARQ-ACK feedback in response to receiving a semi-persistently scheduled PDSCH. The apparatus determines that transmission of the SPS PUCCH HARQ-ACK feedback will overlap with a DL symbol. The transmission of the SPS PUCCH HARQ-ACK feedback is delayed to another UL symbol if the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol. The apparatus transmits the delayed SPS PUCCH HARQ-ACK feedback in one of a next set of available UL symbols, or concurrently with PUCCH HARQ-ACK feedback transmission in a next dynamically scheduled PUCCH after the DL symbol based on a delay feedback configuration configured to define PUCCH content based on the determination that the SPS PUCCH HARQ-ACK feedback will overlap with the DL symbol.

[0001] Cross-reference to related applications

[0002] This application claims the benefit and priority of Greek application serial number 20210100055 entitled “Transmission of Deferred SPS HARQFeedback Coinciding with Current PUCCH”, filed on January 29, 2021, which is expressly incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to communication systems, and more specifically, to the configuration of semi-persistent scheduling (SPS) hybrid automatic repeat request (HARQ) feedback for transmitting delays in wireless communication systems. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources. Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, national, regional, and even global levels. An example telecommunications standard is 5G New Radio (NR). 5G NR is part of the Continuous Mobile Broadband Evolution program promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR can be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in 5G NR technology. These improvements can also be applied to other multiple access technologies and telecommunications standards that adopt these technologies. Summary of the Invention

[0006] Below is a simplified outline of one or more aspects to provide a basic understanding of these aspects. This outline is not a comprehensive overview of all anticipated aspects, nor is it intended to identify key or important elements of all aspects, nor to depict the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed descriptions that follow.

[0007] In one aspect of this disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a device at a UE. The device may be a processor and / or modem at the UE or the UE itself. In response to a received semi-persistent scheduling physical downlink shared channel (PDSCH), the apparatus determines to send a physical uplink control channel (PUCCH) semi-persistent scheduling (SPS) hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback. The apparatus determines that the transmission of the SPS PUCCH HARQ-ACK feedback will overlap with a downlink (DL) symbol, wherein if the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol, the transmission of the SPS PUCCH HARQ-ACK feedback is delayed until another uplink (UL) symbol. Based on the determination that the SPS PUCCH HARQ-ACK feedback will overlap with the DL symbol, the device transmits delayed SPS PUCCH HARQ-ACK feedback simultaneously with the PUCCH HARQ-ACK feedback transmission in one of the next set of available UL symbols, or with the PUCCH HARQ-ACK feedback transmission in the next dynamically scheduled PUCCH after the DL symbol, based on the delayed feedback configured to define the PUCCH content.

[0008] In one aspect of this disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a device at a base station. The device may be a processor and / or modem at the base station or the base station itself. The apparatus provides a user equipment (UE) with a delay feedback configuration for defining PUCCH content, the delay feedback configuration being configured to delay the transmission of a Physical Uplink Control Channel (PUCCH) Semi-Persistent Scheduling (SPS) Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) (HARQ-ACK) feedback in response to a semi-persistently scheduled Physical Downlink Shared Channel (PDSCH), wherein the transmission is delayed if the transmission of the PUCCH SPS HARQ-ACK feedback conflicts with the transmission of a subsequent PUCCH HARQ-ACK feedback in a downlink (DL) symbol or in the next dynamically scheduled PUCCH after the DL symbol. The apparatus transmits the semi-persistently scheduled PDSCH to the UE based on the delay feedback configuration. The apparatus monitors the delayed transmission of the PUCCH SPS HARQ-ACK feedback based on the delay feedback configuration.

[0029] The detailed description that follows, taken in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details for the purpose of providing a comprehensive understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0030] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and methods. These apparatuses and methods will be described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0031] As an example, an element, any part of an element, or any combination of elements can be implemented as a “processing system” including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuitry, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in a processing system can execute software. Software should be interpreted broadly as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, and / or functions, whether referred to as software, firmware, middleware, microcode, hardware description languages, or others.

[0032] Therefore, in one or more example embodiments, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, these functions may be stored on a computer-readable medium or encoded as one or more instructions or code on a computer-readable medium. A computer-readable medium includes a computer storage medium. The storage medium may be any available medium accessible to a computer. By way of example and not limitation, such a computer-readable medium may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage, magnetic disk storage, other magnetic storage devices, combinations of various types of computer-readable media, or any other medium that can be used to store computer-executable code accessible by a computer in the form of instructions or data structures.

[0033] While aspects and implementations are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may arise in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, implementations and / or uses may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchasing devices, medical devices, artificial intelligence (AI)-enabled devices, etc.). While some examples may or may not be specific to a particular use case or application, the broad applicability of the described innovations may be apparent. The range of implementations can extend from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, one or more processors, interleavers, adders / summers, etc.). The innovations described herein are expected to be implemented in devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of various sizes, shapes, and constructions.

[0034] Figure 1 A diagram illustrating an example of a wireless communication system and access network 100 is shown. The wireless communication system (also known as a wireless wide area network (WWAN)) includes a base station 102, a user interface unit (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macro cells include base stations. Small cells include femtocells, picocells, and microcells.

[0035] Base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). Base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with core network 190 via a second backhaul link 184. Among other functions, base station 102 can also perform one or more of the following functions: user data delivery, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, non-access stratum (NAS) message distribution, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, location, and warning message delivery. Base stations 102 can communicate directly or indirectly with each other (e.g., via EPC 160 or core network 190) via a third backhaul link 134 (e.g., an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 can be wired or wireless.

[0036] Base station 102 can wirelessly communicate with UE 104. Each of base stations 102 can provide communication coverage for a corresponding geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, small cell 102' may have coverage area 110' that overlaps with the coverage areas 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. The heterogeneous network may also include a Home Evolution Node B (eNB) (HeNB), which can provide service to a restricted group called a Closed Subscriber Group (CSG). The communication link 120 between base station 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to base station 102 and / or downlink (DL) (also known as forward link) transmission from base station 102 to UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. Base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz per carrier (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.), each carrier being allocated in carrier aggregation for transmission in each direction up to a total of Yx MHz (x component carriers). Carriers may be adjacent to each other or not. Carrier allocation may be asymmetric relative to DL and UL (e.g., more or fewer carriers may be allocated to DL than to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell), and the secondary component carrier may be referred to as the secondary cell (SCell).

[0037] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL WWAN spectrum. D2D communication link 158 can use one or more sidechain channels, such as the Physical Sidechain Broadcast Channel (PSBCH), Physical Sidechain Discovery Channel (PSDCH), Physical Sidechain Shared Channel (PSSCH), and Physical Sidechain Control Channel (PSCCH). D2D communication can be achieved through various wireless D2D communication systems, such as WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0038] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the STA 152 / AP 150 may perform a free channel assessment (CCA) before communication to determine whether the channel is available.

[0039] Cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, cell 102' can employ NR and use the same unlicensed spectrum (e.g., 5 GHz or similar) available to Wi-Fi AP 150. Employing NR in unlicensed spectrum can enhance coverage of the access network and / or increase the access network's capabilities.

[0040] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, the two initial operating bands have been designated as frequency range names FR1 (410 MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). Although a portion of FR1 is greater than 6 GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similar naming issues sometimes arise with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this differs from the Extremely High Frequency (EHF) band (30 GHz – 300 GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0041] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands used for these mid-band frequencies as the frequency range name FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the characteristics of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been designated as the frequency range names FR2-2 (52.6 GHz – 71 GHz), FR4 (71 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher bands falls within the EHF band.

[0042] In light of the foregoing, unless otherwise specified, it should be understood that the use of the term "sub-6 GHz" or similar terms herein can broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specified, it should be understood that the use of the term "millimeter wave" or similar terms herein can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0043] Base station 102, whether a small cell 102' or a larger cell (e.g., a macro base station), may include and / or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations (such as gNB 180) may operate in conventional sub-6 GHz spectrum, millimeter wave frequencies, and / or near-millimeter wave frequencies when communicating with UE 104. When gNB 180 operates at millimeter wave or near-millimeter wave frequencies, gNB 180 may be referred to as a millimeter wave base station. Millimeter wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short range. Base station 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0044] Base station 180 may transmit beamforming signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamforming signals from base station 180 in one or more receive directions 182''. UE 104 may also transmit beamforming signals to base station 180 in one or more transmit directions. Base station 180 may receive beamforming signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 180 / UE 104. The transmit and receive directions for base station 180 may be the same or different. The transmit and receive directions for UE 104 may be the same or different.

[0045] EPC 160 may include Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and Packet Data Network (PDN) Gateway 172. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Typically, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Service 176. IP Service 176 may include the Internet, intranet, IP Multimedia Subsystem (IMS), PS streaming service, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. It can serve as an entry point for content provider MBMS transmission, authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and schedule MBMS transmissions. The MBMS gateway 168 can distribute MBMS services to base station 102 within a Multicast-Broadcast Single Frequency Network (MBSFN) area belonging to a broadcast-specific service, and is responsible for session management (start / stop) and collecting billing information related to eMBMS.

[0046] The core network 190 may include Access and Mobility Management Functions (AMF) 192, other AMFs 193, Session Management Functions (SMF) 194, and User Plane Functions (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196. AMF 192 is the control node that handles signaling between UE 104 and the core network 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are delivered through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 connects to IP services 197. IP services 197 may include the Internet, intranets, IP Multimedia Subsystem (IMS), Packet Switched (PS) Streaming (PSS) services, and / or other IP services.

[0047] Base stations may include and / or be referred to as gNB, Node B, eNB, access point, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Service Set (BSS), Extended Service Set (ESS), Transmitter Receiver Point (TRP), or some other suitable terminology. Base station 102 provides UE 104 with access to EPC 160 or core network 190. Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, medical devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, radio terminal, remote terminal, handheld device, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more accompanying devices in a device constellation arrangement. One or more of these devices may jointly access the network and / or individually access the network.

[0048] Refer again Figure 1In some aspects, UE 104 can be configured to delay the transmission of HARQ-ACK feedback that overlaps with a DL symbol based on a delay feedback configuration. For example, UE 104 may include a delay feedback component 198 configured to delay the transmission of HARQ-ACK feedback that overlaps with a DL symbol based on a delay feedback configuration. UE 104 may determine to transmit PUCCH SPS HARQ-ACK feedback in response to a received semi-persistent PDSCH. UE 104 may determine that the transmission of SPS PUCCH HARQ-ACK feedback will overlap with a DL symbol, wherein if the transmission of SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol, the transmission of SPS PUCCH HARQ-ACK feedback is delayed until another UL symbol. The UE 104 can, based on the determination that the SPSPUCCH HARQ-ACK feedback will overlap with the DL symbol, transmit a delayed SPS PUCCH HARQ-ACK feedback simultaneously with the PUCCH HARQ-ACK feedback transmission in one of the next set of available UL symbols, or with the PUCCH HARQ-ACK feedback transmission in the next dynamically scheduled PUCCH after the DL symbol, based on the delayed feedback configuration configured to define the PUCCH content.

[0049] Refer again Figure 1 In some aspects, base station 180 can be configured to configure the UE to delay the transmission of HARQ-ACK feedback overlapping with DL symbols based on a delay feedback configuration. For example, base station 180 may include configuration component 199 configured to configure the UE to delay the transmission of HARQ-ACK feedback overlapping with DL symbols based on a delay feedback configuration. Base station 180 may provide UE 104 with a delay feedback configuration for defining PUCCH content, which is configured to delay the transmission of PUCCH SPS HARQ-ACK feedback in response to a semi-persistent PDSCH, wherein the transmission of PUCCH SPS HARQ-ACK feedback is delayed if the transmission conflicts with a DL symbol or with a subsequent PUCCH HARQ-ACK feedback transmission in the next dynamically scheduled PUCCH after the DL symbol. Base station 180 may transmit the semi-persistent PDSCH to UE 104 based on the delay feedback configuration. Base station 180 may monitor the delayed transmission of PUCCH SPS HARQ-ACK feedback based on the delay feedback configuration.

[0050] Although the following description may focus on 5G NR, the concepts described herein can be applied to other similar areas such as LTE, LTE-A, CDMA, GSM and other wireless technologies.

[0051] Figure 2AThis is a schematic diagram 200 showing an example of the first subframe within a 5G NR frame structure. Figure 2B This is a schematic diagram 230 illustrating an example of a DL channel within a 5G NR subframe. Figure 2C This is a schematic diagram 250 showing an example of a second subframe within a 5G NR frame structure. Figure 2D This is a schematic diagram 280 illustrating an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD), where for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to either DL or UL, or it can be Time Division Duplex (TDD), where for a given set of subcarriers (carrier system bandwidth), subframes within that set are dedicated to both DL and UL. Figure 2A , Figure 2C In the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (primarily DL), where D is DL, U is UL, and F can be flexibly used between DL / UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3 and 4 are shown with slot formats 1 and 28 respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and all UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and variable symbols. The UE is configured with slot formats via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to the TDD 5G NR frame structure.

[0052] Figures 2A to 2DThe frame structure is illustrated, and aspects of this disclosure can be applied to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is regular or extended. For regular CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL can be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL can be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (also known as Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration equal to 1 / SCS.

[0053]

[0054] For a standard CP (14 symbols / slot), different parameter sets μ 0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a standard CP and parameter set μ, there are 14 symbols / slot and 2... µ Time slot / subframe. Subcarrier spacing can be equal to 2. μ 15 kHz, where μ is the parameter set from 0 to 4. Thus, parameter set μ = 0 has a subcarrier spacing of 15 kHz, and parameter set μ = 4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely proportional to the subcarrier spacing. Figures 2A to 2D An example of a standard frequency division multiplexing (CP) with 14 symbols per slot is provided, along with a parameter set of μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there may be one or more different bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP may have a specific set of parameters and CP (regular or extended).

[0055] A resource grid is used to represent the frame structure. Each time slot consists of a resource block (RB) that extends 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0056] like Figure 2A As shown, some REs carry reference (pilot) signals (RS) for the UE. RSs may include demodulation RS (DM-RS) for channel estimation at the UE (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS). RSs may also include beam measurement RS (BRS), beam refinement RS (BRR), and phase tracking RS (PT-RS).

[0057] Figure 2B Examples of various DL channels within a subframe of a frame are shown. The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbols of an RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during PDCCH monitoring timing on the CORESET, where PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs can be located at higher and / or lower frequencies in the channel bandwidth. The Primary Synchronization Signal (PSS) can be within symbol 2 of a specific subframe of the frame. UE 104 uses the PSS to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) can be within symbol 4 of a specific subframe of the frame. The UE uses the SSS to determine the physical layer cell identification group number and radio frame timing. Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), which carries the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides multiple RBs and System Frame Numbers (SFNs) within the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data and broadcast system information not transmitted via the PBCH, such as System Information Blocks (SIBs) and paging messages.

[0058] like Figure 2CAs shown, some REs carry DM-RS for channel estimation at the base station (indicated as R for a specific configuration, but other DM-RS configurations are possible). The UE can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). PUSCH DM-RS can be transmitted in the first one or two symbols preceding the PUSCH. PUCCH DM-RS can be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and the specific PUCCH format used. The UE can transmit a Sounding Reference Signal (SRS). SRS can be transmitted in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the combs. SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

[0059] Figure 2D Examples of various UL channels within a subframe of a frame are shown. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs). The PUCCH carries data and can also be used to carry buffer status reports (BSR), power headroom reports (PHR), and / or UCI.

[0060] Figure 3This is a block diagram of base station 310 communicating with UE 350 in the access network. In the DL, IP packets from EPC160 can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Serving Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functions associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), mobility between radio access technologies (RATs), and measurement configuration for UE measurement reporting; PDCP layer functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority processing, and logical channel prioritization.

[0061] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1 (including the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domains, and then combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM streams are spatially precoded to produce multiple spatial streams. The channel estimate from channel estimator 374 can be used to determine the decoding and modulation scheme, as well as for spatial processing. The channel estimate can be derived from the reference signal and / or channel condition feedback transmitted by UE 350. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318 TX. Each transmitter 318 TX can modulate a radio frequency (RF) carrier with the corresponding spatial stream for transmission.

[0062] At UE 350, each receiver 354 RX receives signals through its corresponding antenna 352. Each receiver 354 RX recovers the information modulated onto the RF carrier and provides this information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on this information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols and reference signals on each subcarrier are recovered and demodulated by determining the most probable signal constellation point transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. The soft decision is then decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functions.

[0063] The controller / processor 359 may be associated with a memory 360 that stores program code and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0064] Similar to the functions described in conjunction with DL transmission of base station 310, controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with upper-layer PDU transmission, error correction via ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs on TB, demultiplexing of MAC SDUs from TB, scheduling information reporting, error correction via HARQ, priority processing, and logical channel prioritization.

[0065] The channel estimate derived by the channel estimator 358 from the reference signal or feedback transmitted by the base station 310 can be used by the TX processor 368 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354TX. Each transmitter 354TX can modulate an RF carrier with the corresponding spatial stream for transmission.

[0066] The UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318RX receives the signal through its corresponding antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides this information to the RX processor 370.

[0067] The controller / processor 375 may be associated with a memory 376 that stores program code and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transmission and logical channels to recover IP packets from the UE 350. IP packets from the controller / processor 375 can be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0068] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform operations related to... Figure 1 The 198-related aspects.

[0069] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform operations related to... Figure 1 The 199-related aspects.

[0070] Figure 4 This is a schematic diagram 400 illustrating an example of a HARQ feedback conflict with a DL symbol. Schematic diagram 400 includes an example of communication between base station 402 and UE 404. In some cases, base station 402 may send PDSCH 406 to UE 404. UE 404 may receive PDSCH 406 and may be configured to send PUCCH 408, including an acknowledgment (ACK) 414, to base station 402 to confirm whether PDSCH 406 has been received. UE 402 may be configured to send ACK 414 based on the HARQ-ACK feedback timeline or offset (e.g., K1). Figure 4 In the schematic diagram 400, UE 404 has a K1 with 20 symbols, such that UE 402 is scheduled to transmit ACK 414 with an offset of 20 symbols. UE 402 can operate using the time slot format that supports UE 402's K1, such that ACK 414 is scheduled to be transmitted on the uplink (UL) symbols.

[0071] In some cases, changes to the time slot format may occur due to predetermined patterns or scheduling. For example, via base station 402, the network may broadcast a time slot format change to the UE via an RRC information element (IE) (e.g., SlotFormatCombinationsPerCell). In this case, the time slot format may be changed from a first time slot format 410 (e.g., time slot format 42) to a second time slot format 412 (e.g., time slot format 33). For example, both the first and second time slot formats may include a total of 14 time slots, but may have different numbers of time slots (e.g., UL, DL, flexible). For example, the first time slot format (e.g., time slot format 42) may include 3 DL symbols, 3 flexible symbols, and 8 UL symbols, while the second time slot format (e.g., time slot format 33) may include 9 DL symbols, 3 flexible symbols, and 2 UL symbols. If UE 404 receives PDSCH 406 when operating in the second timeslot format, the K1 offset remains the same (e.g., 20 symbols), and HARQ ACK / NACK 416 can be scheduled at the DL symbol, causing HARQ ACK / NACK 416 to conflict with the DL symbol. Thus, UE 404 can avoid sending HARQ ACK / NACK 416 because the 20-symbol offset K1 schedules HARQ ACK / NACK 416 on the DL symbol used for downlink communication from the base station.

[0072] Figure 5 This is a schematic diagram 500 illustrating an example of a HARQ feedback conflict with a DL symbol. Schematic diagram 500 includes an example of communication between base station 502 and UE 504. In the example of schematic diagram 500, the timeslot format remains unchanged, which allows ACK 514 to be properly scheduled for transmission at the UL timeslot. However, in some cases, base station 502 may transmit a dedicated grant (DG) 518 with a PUCCH 522 schedule for transmission from the UE at the UL symbol. In some cases, UE 504 may receive a PDSCH 506 with a different SPS configuration, resulting in the UE being configured with a different K1 offset (e.g., 22 symbols). UE 504 may then receive another PDSCH 506, which configures the UE to revert to the original K1 offset of 20, causing a HARQ ACK / NACK 516 conflict with the DL symbol, preventing UE 504 from transmitting HARQ ACK / NACK 516. The DL symbol that conflicts with HARQ ACK / NACK 516 can be a DL symbol used for downlink transmission in DG microslot 520.

[0073] The aspects provided herein offer a configuration for delaying the transmission of HARQ-ACK feedback that overlaps with DL symbols. For example, a UE can be configured with a delay feedback configuration to delay the transmission of PUCCH SPS HARQ-ACK feedback. When the transmission of PUCCH SPS HARQ-ACK feedback would overlap with DL symbols, the delay feedback configuration can configure the UE to delay the transmission of PUCCH SPS HARQ-ACK under different conditions. At least one advantage of this disclosure is that the delay feedback configuration allows the UE to delay the transmission of PUCCH SPS HARQ-ACK feedback to the first available PUCCH and / or (one or more) UL symbols. At least another advantage of this disclosure is that the delay feedback configuration allows the UE to delay the transmission of PUCCH SPS HARQ-ACK feedback to the Nth available PUCCH resource or the Nth available UL slot, which can help avoid overloading the first available PUCCH and / or (one or more) UL symbols.

[0074] Figure 6 This is a schematic diagram 600 illustrating an example configuration for HARQ feedback used to transmit delays. Schematic diagram 600 is similar to schematic diagram 400. Base station 602 can send PDSCH 606 ​​to UE 604. UE 604 receives PDSCH 606 ​​and can send PUCCH 608, including ACK 614, to the base station. Schematic diagram 600 includes timeslot format changes (e.g., 610, 612), similar to... Figure 4The schematic diagram 400 shows that HARQ ACK / NACK 616 may conflict with DL symbols. However, UE 604 can be configured to delay the transmission of HARQ ACK / NACK 616 to the first available UL symbol. For example, in response to determining that HARQ ACK / NACK 616 overlaps or conflicts with DL symbols, UE 604 can delay the transmission of HARQ ACK / NACK 616 to the first available UL symbol 618. In such a case, UE 604 can delay the transmission of HARQ ACK / NACK 616 to the first available PUCCH resource, which could be the K1+7 symbol. The first available PUCCH resource may include the first available UL sub-slot or symbol, which can carry the exact same delayed HARQ ACK / NACK 616 PUCCH format and the same beam identifier (ID) on the exact PRB. For example, an SPS PUCCH configuration may include PUCCH format 0, length 2 symbols, 1 PRB (e.g., #11), and beam ID #3. The first available PUCCH resources may include the first two available UL symbols (after the time of the SPS HARQ delay) and the same PUB (e.g., #11) and the same beam ID #3 in the new time slot or TDD configuration.

[0075] In some aspects, if the first available UL symbol is incompatible or scheduled to send another uplink transmission, UE 604 can delay the transmission of HARQ ACK / NACK 616 to another available UL symbol. For example, UE 604 can delay the transmission of HARQ ACK / NACK 616 to a second available UL symbol 620. In still other aspects, UE 604 can be configured to delay the transmission of HARQ ACK / NACK 616 to an Nth available UL symbol.

[0076] Return to reference Figure 5 HARQ ACK / NACK 516 conflicts with the DL symbol used for downlink transmission of DG 518. UE 504 can be configured to delay the transmission of HARQ ACK / NACK 516 until the first available UL symbol. However, in Figure 5 In schematic diagram 500, the first available UL symbol overlaps with PUCCH 522 of DG 518. Thus, UE 504 can be configured to combine HARQ ACK / NACK 516 with PUCCH 522.

[0077] UE 504 can be configured with a delay feedback configuration, which uses a set of rules to configure the UE on how to handle instances where the first available PUCCH overlaps with the next scheduled PUCCH. For example, if the next scheduled PUCCH includes resources for transmitting CSI, the UE can replace the CSI with delay feedback (e.g., HARQ ACK / NACK 516 or 616). The UE can then transmit this delay feedback in the CSI resources simultaneously with the HARQ-ACK feedback for the next scheduled PUCCH.

[0078] In some aspects, if the next scheduled PUCCH includes HARQ resources and CSI resources for transmitting HARQ and CSI, the UE can replace the CSI with delay feedback and transmit a PUCCH that includes delay feedback multiplexed with the PUCCH HARQ for the next scheduled PUCCH.

[0079] In some aspects, if the next scheduled PUCCH only includes HARQ resources for transmitting HARQ, the UE can determine whether the PUCCH HARQ for the next scheduled PUCCH can be multiplexed with delay feedback based on whether the multiplexed payload is suitable for the existing PUCCH resources. When the PUCCH HARQ for the next scheduled PUCCH can be multiplexed with delay feedback, the UE can transmit the PUCCH HARQ for the next scheduled PUCCH multiplexed with delay feedback. In some aspects, for example, when the PUCCH HARQ for the next scheduled PUCCH cannot be multiplexed with delay feedback, the UE can replace the PUCCH HARQ for the next scheduled PUCCH with delay feedback and discard the PUCCH HARQ for the next scheduled PUCCH in order to transmit delay feedback in the PUCCH HARQ resources for the next scheduled PUCCH. In some aspects, if the PUCCH HARQ for the next scheduled PUCCH cannot be multiplexed with delay feedback because the multiplexed payload would be unsuitable for existing PUCCH resources, the UE can multiplex the PUCCH HARQ for the next scheduled PUCCH with delay feedback and then estimate the amount of PUCCH resources required for the new multiplexed payload. The UE can then transmit the new multiplexed payload in a PUCCH Resource Indicator (PRI) that can carry the new multiplexed payload or combination, which includes the PUCCH HARQ for the next scheduled PUCCH multiplexed with delay feedback. The base station can be configured to monitor different PRIs for each UE so that the base station can receive the new multiplexed payload or combination.

[0080] Figure 7This is a call flow diagram 700 showing the signaling between UE 702 and base station 704. Base station 704 can be configured to provide at least one cell. UE 702 can be configured to communicate with base station 704. For example, in Figure 1 In the context of this, base station 704 may correspond to base station 102 / 180, and accordingly, the cell may include a geographical coverage area 110 in which communication coverage is provided and / or a small cell 102' having coverage area 110'. Furthermore, UE 702 may at least correspond to UE 104. In another example, in Figure 3 In the context of UE 704, UE 704 can correspond to UE 310, and UE 702 can correspond to UE 350.

[0081] As shown at 706, base station 704 can provide UE 702 with a delay feedback configuration for defining PUCCH content. UE 702 can receive the delay feedback configuration from base station 704. The delay feedback configuration can configure UE 702 to delay the transmission of PUCCH SPS HARQ-ACK feedback in response to a semi-persistent PDSCH, as shown at 708. If the transmission of PUCCH SPS HARQ-ACK feedback conflicts with the transmission of feedback of subsequent PUCCH HARQ-ACK in the next dynamically scheduled PUCCH after the DL symbol, the transmission of PUCCH SPS HARQ-ACK feedback can be delayed based on the delay feedback configuration.

[0082] As shown at 708, base station 704 can send a semi-persistent scheduling PDSCH to UE 702. UE 702 can receive the semi-persistent scheduling PDSCH from base station 704. The transmission of the semi-persistent scheduling PDSCH from base station 704 to UE 702 can be based on delay feedback configuration.

[0083] In some aspects, such as shown at 710, base station 704 may reserve additional PUCCH resources to accommodate delayed transmission of PUCCH SPS HARQ-ACK feedback. In some aspects, the additional PUCCH resources may allow the transmission of different payloads, including PUCCH SPS HARQ-ACK feedback. In some aspects, the additional PUCCH resources may allow transmission of PRI-based PUCCH formats.

[0084] As shown at 712, base station 704 can monitor the delayed transmission of PUCCH SPS HARQ-ACK feedback. Base station 704 can monitor the delayed transmission of PUCCH SPS HARQ-ACK feedback based on the delayed feedback configuration.

[0085] As shown at 714, UE 702 can determine to send PUCCH SPS HARQ-ACK feedback. The UE can determine to send PUCCH SPS HARQ-ACK feedback in response to the received semi-persistent scheduling PDSCH.

[0086] As shown at 716, UE 702 can determine that the transmission of SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol. If the transmission of SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol, the transmission of SPS PUCCH HARQ-ACK feedback can be delayed to another UL symbol. In some aspects, the transmission of SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol in part due to a change in the slot format. The change in slot format may be based on a style or scheduling change in the slot format. For example, PDSCH may be received by a UE operating in a first slot format (e.g., slot format 42) and having a feedback offset (e.g., K1) compatible with the first slot format, such that the feedback is scheduled to be transmitted by the UE in a UL slot. However, in some cases, PDSCH may be received by the UE operating in a second slot format (e.g., slot format 33), such that the feedback offset (K1) is incompatible with the second slot format. In this way, the feedback can be scheduled to be transmitted in the DL time slot in the second time slot format, which will cause a conflict with the downlink transmission from the base station. In this case, the UE can delay the transmission of SPS PUCCH HARQ-ACK to another UL symbol based on the determination that the transmission of SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol.

[0087] As shown at 718, UE 702 can send delayed SPS PUCCH HARQ-ACK feedback. The UE can send delayed SPS PUCCH HARQ-ACK based on the determination of overlap between the SPS PUCCH HARQ-ACK feedback and the DL symbol. The UE can send delayed SPS PUCCH HARQ-ACK feedback in one of the next set of available UL symbols, or simultaneously with the transmission of PUCCH HARQ-ACK feedback in the next dynamically scheduled PUCCH after the DL symbol. The UE can send delayed SPS PUCCH HARQ-ACK feedback based on a delayed feedback configuration configured to define the PUCCH content.

[0088] In some aspects, UE 702 can transmit delayed SPS PUCCH HARQ-ACK feedback in the next set of available UL symbols. The UE can transmit delayed SPS PUCCH HARQ-ACK feedback based on a delayed feedback configuration. The delayed feedback configuration can configure the UE to define PUCCH content and transmit delayed SPS PUCCH HARQ-ACK feedback in the next set of available UL symbols. In some aspects, the next set of available UL symbols may include one or more symbols. In some aspects, delayed SPS PUCCH HARQ-ACK feedback can be transmitted in at least the first available UL symbol in the next set of available UL symbols, which has the same PUCCH format as the delayed SPS PUCCH HARQ-ACK feedback and has similar PRBs and similar beam IDs.

[0089] In some aspects, UE 702 can transmit delayed SPSPUCCH HARQ-ACK feedback simultaneously with PUCCH HARQ-ACK feedback transmission. The UE can also transmit delayed SPS PUCCH HARQ-ACK feedback simultaneously with PUCCH HARQ-ACK feedback transmission in the next scheduled PUCCH after the DL symbol. Delayed feedback configuration allows the UE to define the PUCCH content and transmit delayed SPS PUCCH HARQ-ACK feedback simultaneously with PUCCH HARQ-ACK feedback transmission in the next scheduled PUCCH after the DL symbol.

[0090] In some aspects, if the transmission of delayed SPS PUCCH HARQ-ACK feedback overlaps with the next scheduled PUCCH, UE 702 can determine that the next scheduled PUCCH includes CSI or HARQ resources. In some aspects, the UE can determine that the next scheduled PUCCH includes CSI resources for transmitting CSI. In some aspects, the UE can determine that the next scheduled PUCCH includes HARQ resources and CSI resources for transmitting HARQ and CSI. Delayed feedback configuration can configure the UE to determine whether the next scheduled PUCCH includes CSI or HARQ resources.

[0091] In some aspects, UE 702 can replace CSI with delayed SPS PUCCH HARQ-ACK feedback. If the UE determines that the next scheduled PUCCH includes CSI resources for transmitting the CSI, the UE can replace the CSI with delayed SPS PUCCH HARQ-ACK feedback. In some aspects, if the UE replaces the CSI with delayed SPS PUCCH HARQ-ACK feedback, the CSI is discarded. Delayed feedback configuration can configure the UE to replace CSI with delayed SPS PUCCH HARQ-ACK feedback.

[0092] In some aspects, UE 702 can transmit a delayed SPS PUCCH HARQ-ACK feedback in the CSI resource simultaneously with the PUCCH HARQ-ACK feedback in the scheduled PUCCH. If the next scheduled PUCCH only includes CSI resources for transmitting CSI, the UE can transmit a delayed SPS PUCCH HARQ-ACK feedback in the CSI resource simultaneously with the PUCCH HARQ-ACK feedback in the scheduled PUCCH. In some aspects, the UE can transmit a PUCCH that includes a delayed SPS PUCCH HARQ-ACK feedback multiplexed with the PUCCH HARQ for the next scheduled PUCCH. If the next scheduled PUCCH includes HARQ resources and CSI resources for transmitting HARQ and CSI, the UE can transmit a PUCCH that includes a delayed SPS PUCCH HARQ-ACK feedback multiplexed with the PUCCH HARQ for the next scheduled PUCCH. The UE can send delayed SPS PUCCH HARQ-ACK feedback based on the delay feedback configuration, either from the CSI resource or multiplexed with the PUCCH HARQ for the next scheduling.

[0093] In some aspects, if the transmission of delayed SPS PUCCH HARQ-ACK feedback overlaps with the next scheduled PUCCH, UE 702 can determine that the next scheduled PUCCH includes only the resources for PUCCH HARQ-ACK feedback for the next scheduled PUCCH. The UE can determine the resources for the next scheduled PUCCH based on the delayed feedback configuration.

[0094] In some aspects, UE 702 can determine whether delayed SPS PUCCH HARQ-ACK feedback can be multiplexed with PUCCH HARQ-ACK feedback for the next scheduled PUCCH based on whether the combination of delayed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback for the next scheduled PUCCH is suitable for existing PUCCH resources. The UE can also determine whether delayed SPS PUCCH HARQ-ACK feedback can be multiplexed with PUCCH HARQ-ACK feedback for the next scheduled PUCCH based on the delayed feedback configuration.

[0095] In some aspects, UE 702 can simultaneously transmit multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback within the scheduled PUCCH resources. The UE can transmit multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback simultaneously within the scheduled PUCCH resources, provided that both can be multiplexed into the same scheduled PUCCH resource.

[0096] In some aspects, when a delayed SPS PUCCH HARQ-ACK feedback cannot be multiplexed with a PUCCH HARQ-ACK feedback used for the next scheduled PUCCH, UE 702 can replace the PUCCH HARQ-ACK feedback used for the next scheduled PUCCH with the delayed SPS PUCCH HARQ-ACK feedback. In some aspects, the delayed SPS PUCCH HARQ-ACK feedback cannot be multiplexed with the PUCCH HARQ-ACK feedback used for the next scheduled PUCCH because the combination of feedbacks is incompatible or unsuitable within existing PUCCH resources. The UE can configure the delayed feedback to replace the PUCCH HARQ-ACK feedback used for the next scheduled PUCCH with the delayed SPS PUCCH HARQ-ACK feedback.

[0097] In some aspects, UE 702 can transmit delayed SPS PUCCH HARQ-ACK feedback in the PUCCH resources used for the next scheduled PUCCH. In such aspects, since the PUCCH HARQ-ACK feedback for the next scheduled PUCCH is replaced by delayed SPS PUCCH HARQ-ACK feedback, the PUCCH HARQ-ACK feedback for the next scheduled PUCCH can be discarded. The UE can configure the transmission of delayed SPS PUCCH HARQ-ACK feedback in the PUCCH resources used for the next scheduled PUCCH based on the delayed feedback configuration.

[0098] In some aspects, UE 702 can multiplex the PUCCH HARQ-ACK feedback for the next scheduled PUCCH and the delayed SPS PUCCH HARQ-ACK feedback. When it is determined that the delayed SPS PUCCH HARQ-ACK feedback can be multiplexed with the PUCCH HARQ-ACK feedback for the next scheduled PUCCH, the UE can multiplex the PUCCH HARQ-ACK feedback for the next scheduled PUCCH and the delayed SPS PUCCH HARQ-ACK feedback. The UE can multiplex the PUCCH HARQ-ACK feedback for the next scheduled PUCCH and the delayed SPS PUCCH HARQ-ACK feedback based on the delayed feedback configuration.

[0099] In some aspects, UE 702 can determine the amount of PUCCH resources required for transmitting and multiplexing the delayed SPS PUCCH HARQ-ACK feedback for the PUCCH used in the next scheduled PUCCH. In response to multiplexing the PUCCH HARQ-ACK feedback for the next scheduled PUCCH and the delayed SPS PUCCH HARQ-ACK feedback, the UE can determine the amount of PUCCH resources required for transmitting and multiplexing the delayed SPS PUCCH HARQ-ACK feedback for the PUCCH used in the next scheduled PUCCH. The UE can determine the required amount of PUCCH resources based on the delayed feedback configuration.

[0100] In some aspects, UE 702 can transmit PUCCH HARQ-ACK feedback multiplexed with delayed SPS PUCCH HARQ-ACK feedback for the next scheduled PUCCH in a new PUCCH resource based on the PRI. Where neither the SPS PUCCH HARQ-ACK feedback nor the PUCCH HARQ-ACK feedback can be multiplexed into the same scheduled PUCCH resource, the UE can utilize the new PUCCH resource to transmit PUCCH HARQ-ACK feedback multiplexed with delayed SPS PUCCH HARQ-ACK feedback for the next scheduled PUCCH. In some aspects, the PRI includes resources for multiple different payloads, wherein the PRI can support the transmission of PUCCH HARQ-ACK feedback multiplexed with delayed SPS PUCCH HARQ-ACK feedback for the next scheduled PUCCH. For example, a PRI may include new PUCCH resources, which may include resources for different payloads, enabling the transmission of PUCCH HARQ-ACK feedback for the next scheduled PUCCH that is multiplexed with delayed SPS PUCCH HARQ-ACK feedback.

[0101] In some aspects, base station 704 can simultaneously receive multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback. The base station can receive multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback in additional PUCCH resources. These additional PUCCH resources are reserved by the base station to accommodate delayed transmission of PUCCH SPS HARQ-ACK feedback.

[0102] In some aspects, base station 704 can simultaneously receive multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback. The base station can simultaneously receive multiplexed SPS PUCCH HARQ-ACK feedback and PUCCH HARQ-ACK feedback within the scheduled PUCCH resources.

[0103] Figure 8 This is a flowchart 800 of a wireless communication method. This method can be performed by a UE or a component of the UE (e.g., UE 104; device 1302). One or more of the operations shown can be omitted, rearranged, or performed simultaneously. This method allows the UE to configure the transmission of HARQ-ACK feedback with delays overlapping with DL symbols based on delay feedback.

[0104] At point 802, the UE can determine to send PUCCH SPS HARQ-ACK feedback. For example, 802 can be performed by the determination component 1340 of device 1302. The UE can determine to send PUCCH SPSHARQ-ACK feedback in response to the received semi-persistent scheduling PDSCH.

[0105] At 804, the UE can determine that the transmission of the SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol. For example, 804 can be performed by the overlap component 1342 of device 1302. If the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol, the transmission of the SPS PUCCH HARQ-ACK feedback can be delayed to another UL symbol. In some aspects, the transmission of the SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol in part due to a change in the slot format. The change in the slot format may be based on a style or scheduling change in the slot format. For example, the PDSCH may be received by a UE operating in a first slot format (e.g., slot format 42) and having a feedback offset (e.g., K1) compatible with the first slot format, such that the feedback is scheduled to be transmitted by the UE in a UL slot. However, in some cases, the PDSCH may be received by the UE operating in a second slot format (e.g., slot format 33), such that the feedback offset (K1) is incompatible with the second slot format. In this way, the feedback can be scheduled to be transmitted in the DL time slot of the second time slot format, which will cause a conflict with the downlink transmission from the base station. In this case, the UE can delay the transmission of SPS PUCCHHARQ-ACK to another UL symbol based on the determination that the transmission of SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol.

[0106] At point 806, the UE can send a delayed SPS PUCCH HARQ-ACK feedback. For example, 806 can be performed by the delay feedback component 1344 of device 1302. The UE can send the delayed SPS PUCCH HARQ-ACK based on the determination that the SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol. The UE can send the delayed SPS PUCCH HARQ-ACK feedback in one of the next set of available UL symbols, or simultaneously with the PUCCH HARQ-ACK feedback in the next dynamically scheduled PUCCH after the DL symbol. The UE can send the delayed SPS PUCCH HARQ-ACK feedback based on a delay feedback configuration configured to define the PUCCH content.

[0107] Figure 9This is a flowchart 900 of a wireless communication method. This method can be performed by a UE or a component of the UE (e.g., UE 104; device 1302).

[0109] At 904, the UE can determine that the transmission of the SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol. For example, 904 can be performed by the overlap component 1342 of device 1302. If the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with a DL symbol, the transmission of the SPS PUCCH HARQ-ACK feedback can be delayed to another UL symbol. In some aspects, the transmission of the SPS PUCCH HARQ-ACK feedback may overlap with a DL symbol in part due to a change in the slot format. The change in the slot format may be based on a style or scheduling change in the slot format. For example, the PDSCH may be received by a UE operating in a first slot format (e.g., slot format 42) and having a feedback offset (e.g., K1) compatible with the first slot format, such that the feedback is scheduled to be transmitted by the UE in a UL slot. However, in some cases, the PDSCH may be received by the UE operating in a second slot format (e.g., slot format 33), such that the feedback offset (K1) is incompatible with the second slot format. In this way, the feedback can be scheduled to be transmitted in the DL time slot of the second time slot format, which will cause a conflict with the downlink transmission from the base station. In this case, the UE can delay the transmission of SPS PUCCHHARQ-ACK to another UL symbol based on the determination that the transmission of SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol.

[0110] At 906, the UE can send a delayed SPS PUCCH HARQ-ACK feedback. For example, 906 can be performed by the delayed feedback component 1344 of device 1302. The UE can send the delayed SPS PUCCH HARQ-ACK based on the determination that the SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol. The UE can send the delayed SPS PUCCH HARQ-ACK feedback in one of the next set of available UL symbols, or simultaneously with the PUCCH HARQ-ACK feedback in the next dynamically scheduled PUCCH after the DL symbol. The UE can send the delayed SPS PUCCH HARQ-ACK feedback based on a delayed feedback configuration configured to define the PUCCH content.

[0111] At point 908, the UE can transmit delayed SPS PUCCH HARQ-ACK feedback in the next set of available UL symbols.

The delayed feedback configuration can configure the UE to define PUCCH content and transmit delayed SPS PUCCH HARQ-ACK feedback in the next set of available UL symbols. In some aspects, the next set of available UL symbols may include one or more symbols. In some aspects, the delayed SPS PUCCH HARQ-ACK feedback can be transmitted in at least a first available UL symbol in the next set of available UL symbols, which has the same PUCCH format as the delayed SPS PUCCH HARQ-ACK feedback and has similar PRBs and similar beam IDs.

[0112] At point 910, the UE can transmit a delayed SPS PUCCH HARQ-ACK feedback simultaneously with the PUCCH HARQ-ACK feedback transmission. For example, 910 can be performed by the delay feedback component 1344 of device 1302. The UE can transmit a delayed SPS PUCCH HARQ-ACK feedback simultaneously with the PUCCH HARQ-ACK feedback transmission in the next scheduled PUCCH after the DL symbol. The delay feedback configuration allows the UE to define the PUCCH content and transmit the delayed SPS PUCCH HARQ-ACK feedback simultaneously with the PUCCH HARQ-ACK feedback transmission in the next scheduled PUCCH after the DL symbol.

[0113] At point 912, if the transmission of delayed SPS PUCCH HARQ-ACK feedback overlaps with the next scheduled PUCCH, the UE can determine that the next scheduled PUCCH includes CSI or HARQ resources. For example, 912 can be performed by the determining component 1340 of device 1302. In some aspects, the UE can determine that the next scheduled PUCCH includes CSI resources for transmitting CSI. In some aspects, the UE can determine that the next scheduled PUCCH includes HARQ resources and CSI resources for transmitting HARQ and CSI. Delayed feedback configuration can configure the UE to determine whether the next scheduled PUCCH includes CSI or HARQ resources.

[0114] At point 914, the UE can replace the CSI with a delayed SPS PUCCH HARQ-ACK feedback. For example, 914 can be performed by the delayed feedback component 1344 of device 1302. If the UE determines that the next scheduled PUCCH includes CSI resources for transmitting the CSI, the UE can replace the CSI with a delayed SPS PUCCH HARQ-ACK feedback. In some aspects, if the UE replaces the CSI with a delayed SPS PUCCH HARQ-ACK feedback, the CSI is discarded. Delayed feedback configuration can configure the UE to replace the CSI with a delayed SPS PUCCH HARQ-ACK feedback.

[0115] At point 916, the UE can transmit a delayed SPS PUCCH HARQ-ACK feedback. For example, 916 can be performed by the delayed feedback component 1344 of device 1302. In some aspects, the UE can transmit the delayed SPS PUCCH HARQ-ACK feedback in CSI resources simultaneously with the PUCCH HARQ-ACK feedback in the scheduled PUCCH. If the next scheduled PUCCH only includes CSI resources for transmitting CSI, the UE can transmit the delayed SPS PUCCH HARQ-ACK feedback in CSI resources simultaneously with the PUCCH HARQ-ACK feedback in the scheduled PUCCH. In some aspects, the UE can transmit a PUCCH that includes delayed SPS PUCCH HARQ-ACK feedback multiplexed with the PUCCH HARQ for the next scheduled PUCCH. If the next scheduled PUCCH includes HARQ resources and CSI resources for transmitting HARQ and CSI, the UE can transmit a PUCCH that includes an SPS PUCCH HARQ-ACK feedback with a delay multiplexed with the PUCCH HARQ for the next scheduled PUCCH. The UE can transmit the SPS PUCCH HARQ-ACK feedback with a delay multiplexed with the PUCCH HARQ for the next scheduled PUCCH based on the delay feedback configuration.

[0116] Figure 10 This is a flowchart 1000 of a wireless communication method. The method can be performed by a UE or a component of the UE (e.g., UE 104; device 1302). One or more of the operations shown can be omitted, rearranged, or performed simultaneously.

However, in some cases, the PDSCH may be received by the UE operating in a second slot format (e.g., slot format 33), such that the feedback offset (K1) is incompatible with the second slot format. In this way, the feedback can be scheduled to be transmitted in the DL time slot of the second time slot format, which will cause a conflict with the downlink transmission from the base station. In this case, the UE can delay the transmission of SPS PUCCHHARQ-ACK to another UL symbol based on the determination that the transmission of SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol.
