AI Technical Summary
Existing wireless communication systems face challenges in efficiently managing configured grant (CG) physical uplink shared channel (PUSCH) occasions, particularly in avoiding collisions with synchronization signal blocks (SSBs) or transient periods, which leads to invalid CG PUSCH occasions and increased computational complexity and signaling overhead.
A method where a user equipment (UE) receives a configuration of CG PUSCH occasions from a network entity and transmits unused transmission occasions indicated by uplink control information (UCI), excluding invalid CG PUSCH occasions that collide with SSBs or transient periods, thereby refraining from determining hybrid automatic repeat request identifiers (HARQ-IDs) for these invalid occasions.
This approach reduces computational complexity at the UE and signaling overhead in the wireless communication system by avoiding the processing of invalid CG PUSCH occasions and optimizing the usage indications in UCI, leading to more efficient HARQ management.

Abstract
Description
INVALID CG PUSCH TO FOR HD-FDD UETECHNICAL FIELD
[0001] The present disclosure relates generally to communication systems, and more particularly, to wireless communication systems with configured grant (CG) physical uplink shared channel (PUSCH) occasions.
[0002] INTRODUCTION
[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting 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.
[0004] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with 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 may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

[0027] The detailed description set forth below in connection with the drawings describes various configurations and does not represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0028] Several aspects of telecommunication systems are presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0029] By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. When multiple processors are implemented, the multiple processors may perform the functions individually or in combination. 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, systems on a chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise, shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.
[0030] A network may provide a user equipment (UE) with a configured grant (CG) of periodic or semi-static resources that the UE can use for uplink transmissions. For example, based on the CG, the UE may transmit uplink transmissions in transmission occasions (TOs) of the CG without a separate grant for different TOs. In some aspects, the network may indicate a CG for the UE in radio resource control (RRC) signaling. In some aspects, the UE may receive an activation or deactivation of the CG, e.g., in a medium access control-control element (MAC-CE) or downlink control information (DCI) . In some aspects, the UE may be able to use the resources of the CG based on the RRC configuration and without a further activation. In some aspects, a UE may provide an indication, e.g., in uplink control information (UCI) (UTO-UCI) , informing the network that the UE will not use one or more TOs of the CG. Such a notification enables the network to use the TOs for other communication.
[0031] One or more of the TOs may not be valid for a UE to use, e.g., based on a collision with other resources or signals. In some wireless communication systems, the UE may still determine a hybrid automatic repeat request identifier (HARQ-ID) for invalid CG physical uplink shared channel (PUSCH) TOs and may still inform the network in the UTO-UCI regarding whether an invalid CG PUSCH TO will be used. The UE may determine a HARQ-ID for the first configured CG PUSCH TO (regardless of whether it is valid or not) within a multi-CG PUSCH PO period and determine HARQ-ID for subsequent valid CG PUSCH occasions within the CG period. In some aspects, the UE may not indicate whether invalid CG PUSCH occasion (s) are used or not used in the UTO-UCI. Aspects provided herein enable a UE to refrain from determining HARQ-ID for a CG PUSCH TO and refrain from indicating whether the CG PUSCH TO is used or not used in the UTO-UCI when the CG PUSCH TO collides with a transient period of an SSB so that computational complexity at the UE and the signaling overhead in the wireless communication system may be reduced.
[0032] Accordingly, in one or more example aspects, implementations, and / or use cases, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, such computer-readable media can include a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.
[0033] While aspects, implementations, and / or use cases are described in this application by illustration to some examples, additional or different aspects, implementations and / or use cases may come about in many different arrangements and scenarios. Aspects, implementations, and / or use cases described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, aspects, implementations, and / or use cases may come about via integrated chip implementations and other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, artificial intelligence (AI) -enabled devices, etc. ) . While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described examples may occur. Aspects, implementations, and / or use cases may range a spectrum from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more techniques herein. In some practical settings, devices incorporating described aspects and features may also include additional components and features for implementation and practice of claimed and described aspect. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes (e.g., hardware components including antenna, RF-chains, power amplifiers, modulators, buffer, processor (s) , interleaver, adders / summers, etc. ) . Techniques described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. of varying sizes, shapes, and constitution.
[0034] Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element, or a network equipment, such as a base station (BS) , or one or more units (or one or more components) performing base station functionality, may be implemented in an aggregated or disaggregated architecture. For example, a BS (such as a Node B (NB) , evolved NB (eNB) , NR BS, 5G NB, access point (AP) , a transmission reception point (TRP) , or a cell, etc. ) may be implemented as an aggregated base station (also known as a standalone BS or a monolithic BS) or a disaggregated base station.
[0035] An aggregated base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A disaggregated base station may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more central or centralized units (CUs) , one or more distributed units (DUs) , or one or more radio units (RUs)) . In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other RAN nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU and RU can be implemented as virtual units, i.e., a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) .
[0036] Base station operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (such as the network configuration sponsored by the O-RAN Alliance)) , or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN) ) . Disaggregation may include distributing functionality across two or more units at various physical locations, as well as distributing functionality for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station, or disaggregated RAN architecture, can be configured for wired or wireless communication with at least one other unit.
[0037] FIG. 1 is a diagram 100 illustrating an example of a wireless communications system and an access network. The illustrated wireless communications system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that can communicate directly with a core network 120 via a backhaul link, or indirectly with the core network 120 through one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 125 via an E2 link, or a Non-Real Time (Non-RT) RIC 115 associated with a Service Management and Orchestration (SMO) Framework 105, or both) . A CU 110 may communicate with one or more DUs 130 via respective midhaul links, such as an F1 interface. The DUs 130 may communicate with one or more RUs 140 via respective fronthaul links. The RUs 140 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 140.
[0038] Each of the units, i.e., the CUs 110, the DUs 130, the RUs 140, as well as the Near-RT RICs 125, the Non-RT RICs 115, and the SMO Framework 105, may include one or more interfaces or be coupled to one or more interfaces configured to receive or to transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or to transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units can include a wireless interface, which may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) , configured to receive or to transmit signals, or both, over a wireless transmission medium to one or more of the other units.
[0039] In some aspects, the CU 110 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) , packet data convergence protocol (PDCP) , service data adaptation protocol (SDAP) , or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 110. The CU 110 may be configured to handle user plane functionality (i.e., Central Unit –User Plane (CU-UP) ) , control plane functionality (i.e., Central Unit –Control Plane (CU-CP)) , or a combination thereof. In some implementations, the CU 110 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as an E1 interface when implemented in an O-RAN configuration. The CU 110 can be implemented to communicate with the DU 130, as necessary, for network control and signaling.
[0040] The DU 130 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 140. In some aspects, the DU 130 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation, demodulation, or the like) depending, at least in part, on a functional split, such as those defined by 3GPP. In some aspects, the DU 130 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 130, or with the control functions hosted by the CU 110.
[0041] Lower-layer functionality can be implemented by one or more RUs 140. In some deployments, an RU 140, controlled by a DU 130, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT) , inverse FFT (iFFT) , digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like) , or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU (s) 140 can be implemented to handle over the air (OTA) communication with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU (s) 140 can be controlled by the corresponding DU 130. In some scenarios, this configuration can enable the DU (s) 130 and the CU 110 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0042] The SMO Framework 105 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements that may be managed via an operations and maintenance interface (such as an O1 interface) . For virtualized network elements, the SMO Framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 190) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface) . Such virtualized network elements can include, but are not limited to, CUs 110, DUs 130, RUs 140 and Near-RT RICs 125. In some implementations, the SMO Framework 105 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 111, via an O1 interface. Additionally, in some implementations, the SMO Framework 105 can communicate directly with one or more RUs 140 via an O1 interface. The SMO Framework 105 also may include a Non-RT RIC 115 configured to support functionality of the SMO Framework 105.
[0043] The Non-RT RIC 115 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 125. The Non-RT RIC 115 may be coupled to or communicate with (such as via an A1 interface) the Near-RT RIC 125. The Near-RT RIC 125 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 110, one or more DUs 130, or both, as well as an O-eNB, with the Near-RT RIC 125.
[0044] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 125, the Non-RT RIC 115 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 125 and may be received at the SMO Framework 105 or the Non-RT RIC 115 from non-network data sources or from network functions. In some examples, the Non-RT RIC 115 or the Near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 115 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 105 (such as reconfiguration via O1) or via creation of RAN management policies (such as A1 policies) .
[0045] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Accordingly, a base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component indicated with dotted lines to signify that each component may or may not be included in the base station 102) . The base station 102 provides an access point to the core network 120 for a UE 104. The base station 102 may include macrocells (high power cellular base station) and / or small cells (low power cellular base station) . The small cells include femtocells, picocells, and microcells. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs) , which may provide service to a restricted group known as a closed subscriber group (CSG) . The communication links between the RUs 140 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to an RU 140 and / or downlink (DL) (also referred to as forward link) transmissions from an RU 140 to a UE 104. The communication links may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication links may be through one or more carriers. The base station 102 / UEs 104 may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) . The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell) .
[0046] Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL / UL wireless wide area network (WWAN) spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH) , a physical sidelink discovery channel (PSDCH) , a physical sidelink shared channel (PSSCH) , and a physical sidelink control channel (PSCCH) . D2D communication may be through a variety of wireless D2D communications systems, such as for example, BluetoothTM (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG) ) , Wi-FiTM (Wi-Fi is a trademark of the Wi-Fi Alliance) based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.
[0047] The wireless communications system may further include a Wi-Fi AP 150 in communication with UEs 104 (also referred to as Wi-Fi stations (STAs)) via communication link 154, e.g., in a 5 GHz unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the UEs 104 / AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.
[0048] The electromagnetic spectrum is often subdivided, based on frequency / wavelength, into various classes, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz –7.125 GHz) and FR2 (24.25 GHz –52.6 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.
[0049] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz –24.25 GHz) . Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend features of FR1 and / or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6 GHz –71 GHz) , FR4 (71 GHz –114.25 GHz) , and FR5 (114.25 GHz –300 GHz) . Each of these higher frequency bands falls within the EHF band.
[0050] With the above aspects in mind, unless specifically stated otherwise, the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.
[0051] The base station 102 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate beamforming. The base station 102 may transmit a beamformed signal 182 to the UE 104 in one or more transmit directions. The UE 104 may receive the beamformed signal from the base station 102 in one or more receive directions. The UE 104 may also transmit a beamformed signal 184 to the base station 102 in one or more transmit directions. The base station 102 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 102 / UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 102 / UE 104. The transmit and receive directions for the base station 102 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.
[0052] The base station 102 may include and / or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a TRP, network node, network entity, network equipment, or some other suitable terminology. The base station 102 can be implemented as an integrated access and backhaul (IAB) node, a relay node, a sidelink node, an aggregated (monolithic) base station with a baseband unit (BBU) (including a CU and a DU) and an RU, or as a disaggregated base station including one or more of a CU, a DU, and / or an RU. The set of base stations, which may include disaggregated base stations and / or aggregated base stations, may be referred to as next generation (NG) RAN (NG-RAN) .
[0053] The core network 120 may include an Access and Mobility Management Function (AMF) 161, a Session Management Function (SMF) 162, a User Plane Function (UPF) 163, a Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. The AMF 161 is the control node that processes the signaling between the UEs 104 and the core network 120. The AMF 161 supports registration management, connection management, mobility management, and other functions. The SMF 162 supports session management and other functions. The UPF 163 supports packet routing, packet forwarding, and other functions. The UDM 164 supports the generation of authentication and key agreement (AKA) credentials, user identification handling, access authorization, and subscription management. The one or more location servers 168 are illustrated as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, the one or more location servers 168 may include one or more location / positioning servers, which may include one or more of the GMLC 165, the LMF 166, a position determination entity (PDE) , a serving mobile location center (SMLC) , a mobile positioning center (MPC) , or the like. The GMLC 165 and the LMF 166 support UE location services. The GMLC 165 provides an interface for clients / applications (e.g., emergency services) for accessing UE positioning information. The LMF 166 receives measurements and assistance information from the NG-RAN and the UE 104 via the AMF 161 to compute the position of the UE 104. The NG-RAN may utilize one or more positioning methods in order to determine the position of the UE 104. Positioning the UE 104 may involve signal measurements, a position estimate, and an optional velocity computation based on the measurements. The signal measurements may be made by the UE 104 and / or the base station 102 serving the UE 104. The signals measured may be based on one or more of a satellite positioning system (SPS) 170 (e.g., one or more of a Global Navigation Satellite System (GNSS) , global position system (GPS) , non-terrestrial network (NTN) , or other satellite position / location system) , LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS) , sensor-based information (e.g., barometric pressure sensor, motion sensor) , NR enhanced cell ID (NR E-CID) methods, NR signals (e.g., multi-round trip time (Multi-RTT) , DL angle-of-departure (DL-AoD) , DL time difference of arrival (DL-TDOA) , UL time difference of arrival (UL-TDOA) , and UL angle-of-arrival (UL-AoA) positioning) , and / or other systems / signals / sensors.
[0054] Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA) , a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player) , a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc. ) . The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices such as in a device constellation arrangement. One or more of these devices may collectively access the network and / or individually access the network.
[0055] Referring again to FIG. 1, in some aspects, the UE 104 may include a CG component 198. In some aspects, the CG component 198 may be configured to receive, from a network entity, a configuration of a set of CG PUSCH occasions. In some aspects, the CG component 198 may be further configured to transmit, to the network entity, UTO-UCI including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one HARQ-ID associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB.
[0056] In certain aspects, the base station 102 may include a CG component 199. In some aspects, the CG component 199 may be configured to transmit, for a UE, a configuration of a set of CG PUSCH occasions. In some aspects, the CG component 199 may be further configured to receive UTO-UCI including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one HARQ-ID associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB.
[0057] Although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.
[0058] As described herein, a node (which may be referred to as a node, a network node, a network entity, or a wireless node) may include, be, or be included in (e.g., be a component of) a base station (e.g., any base station described herein) , a UE (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, an integrated access and backhauling (IAB) node, a distributed unit (DU) , a central unit (CU) , a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU) ) , and / or another processing entity configured to perform any of the techniques described herein. For example, a network node may be a UE. As another example, a network node may be a base station or network entity. As another example, a first network node may be configured to communicate with a second network node or a third network node. In one aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a UE. In another aspect of this example, the first network node may be a UE, the second network node may be a base station, and the third network node may be a base station. In yet other aspects of this example, the first, second, and third network nodes may be different relative to these examples. Similarly, reference to a UE, base station, apparatus, device, computing system, or the like may include disclosure of the UE, base station, apparatus, device, computing system, or the like being a network node. For example, disclosure that a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node. Consistent with this disclosure, once a specific example is broadened in accordance with this disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node) , the broader example of the narrower example may be interpreted in the reverse, but in a broad open-ended way. In the example above where a UE is configured to receive information from a base station also discloses that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more one or more components, a first processing entity, or the like configured to receive the information; and the second network node may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, or the like.
[0059] As described herein, communication of information (e.g., any information, signal, or the like) may be described in various aspects using different terminology. Disclosure of one communication term includes disclosure of other communication terms. For example, a first network node may be described as being configured to transmit information to a second network node. In this example and consistent with this disclosure, disclosure that the first network node is configured to transmit information to the second network node includes disclosure that the first network node is configured to provide, send, output, communicate, or transmit information to the second network node. Similarly, in this example and consistent with this disclosure, disclosure that the first network node is configured to transmit information to the second network node includes disclosure that the second network node is configured to receive, obtain, or decode the information that is provided, sent, output, communicated, or transmitted by the first network node.
[0060] FIG. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by FIGs. 2A, 2C, the 5G NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL) , where D is DL, U is UL, and F is flexible for use between DL / UL, and subframe 3 being configured with slot format 1 (with all UL) . While subframes 3, 4 are shown with slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI) , or semi-statically / statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI) . Note that the description infra applies also to a 5G NR frame structure that is TDD.
[0061] FIGs. 2A-2D illustrate a frame structure, and the aspects of the present disclosure may be applicable to other wireless communication technologies, which may have a different frame structure and / or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms) . Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot may include 14 symbols, and for extended CP, each slot may include 12 symbols. The symbols on DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (for power limited scenarios; limited to a single stream transmission) . The number of slots within a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) (see Table 1) . The symbol length / duration may scale with 1 / SCS.
[0062] Table 1: Numerology, SCS, and CP
[0063] For normal CP (14 symbols / slot) , different numerologies μ 0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For extended CP, the numerology 2 allows for 4 slots per subframe. Accordingly, for normal CP and numerology μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing may be equal to 2μ*15 kHz, where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIGs. 2A-2D provide an example of normal CP with 14 symbols per slot and numerology 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 parts (BWPs) (see FIG. 2B) that are frequency division multiplexed. Each BWP may have a particular numerology and CP (normal or extended) .
[0064] A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs) ) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs) . The number of bits carried by each RE depends on the modulation scheme.
[0065] As illustrated in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE.The RS may include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS) , beam refinement RS (BRRS) , and phase tracking RS (PT-RS) .
[0066] FIG. 2B illustrates an example of various DL channels within a subframe of a frame. 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 including six RE groups (REGs) , each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET) . A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater and / or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe / symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI) . Based on the PCI, the UE can determine the locations of the DM-RS. The physical broadcast channel (PBCH) , which carries a master information block (MIB) , may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as SS block (SSB) ) . The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN) . The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs) , and paging messages.
[0067] As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH) . The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS) . The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
[0068] FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) , such as scheduling requests, a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a rank indicator (RI) , and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACK and / or negative ACK (NACK) ) . The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR) , a power headroom report (PHR) , and / or UCI.
[0069] FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, Internet protocol (IP) packets may be provided to a controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs) , RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release) , inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification) , and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs) , error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs) , re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) , demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0070] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding / decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations 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 coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate a radio frequency (RF) carrier with a respective spatial stream for transmission.
[0071] At the UE 350, each receiver 354Rx receives a signal through its respective antenna 352. Each receiver 354Rx recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT) . The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.
[0072] The controller / processor 359 can be associated with at least one memory 360 that stores program codes and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0073] Similar to the functionality described in connection with the DL transmission by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression / decompression, and security (ciphering, deciphering, integrity protection, integrity verification) ; RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.
[0074] Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antenna 352 via separate transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a respective spatial stream for transmission.
[0075] The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318Rx receives a signal through its respective antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to a RX processor 370.
[0076] The controller / processor 375 can be associated with at least one memory 376 that stores program codes and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
[0077] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform aspects in connection with CG component 198 of FIG. 1.
[0078] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform aspects in connection with CG component 199 of FIG. 1.
[0079] A configured grant provides a UE with periodic or semi-persistent resources that the UE may use for uplink transmissions to the network. For example, the network may transmit a configuration to a UE for one or more CGs of recurring resources for uplink transmission in RRC signaling to the UE. For some types of CGs, the UE may use the allocated resources based on the RRC configuration and without activation or control signaling from the network. In other types of CGs, the UE may further receive an indication that the configured grant is activated or enabled for the UE to use, e.g., in a MAC-CE or DCI. The UE may then use the recurring resources of the configured grant for uplink transmissions, e.g., until the UE receives signaling from the network that the configured grant is deactivated. In some aspects, the UE may receive RRC signaling configuring multiple configured grants for the UE, and the UE may then receive a MAC-CE that activates one or more of the configured grants from the RRC signaling. The configured grant provides the UE with an allocation of resources that the UE can use for uplink transmissions without individual grants, e.g., in DCI, for individual uplink transmissions. The configured grant can reduce the overhead for signaling grants to the UE and can reduce latency for the UE to transmit uplink transmissions.
[0080] In some wireless communication systems, a CG may be configured for PUSCH transmissions of the UE such that multiple PUSCH transmission occasions (TOs) may be included in each period (e.g., for licensed spectrum) and the UE may transmit an UTO-UCI to the network to indicate whether or not the UE will use each of the multiple PUSCH TOs, e.g., with a separate indication for each of the TOs. As used herein, the term “PUSCH occasion” may be used interchangeably with “PUSCH TO” and may refer to a frequency resource and a time resource that may be used for PUSCH transmission. The PUSCH occasion may be associated with a DM-RS resource which may be provided by a DM-RS configuration. In some wireless communication systems, configured CG resources may be used to reduce UL transmission latency that may be caused by scheduling request (SR) and buffer status report (BSR) based resource request for UL high data rate and low latency periodic traffic. For example, the network may configure multiple CG PUSCH TOs in each cycle (e.g., which may be determined based on an application associated with the UE, such as extended reality (XR) or other types of applications) of UL traffic and the UE may be able to immediately start transmitting PUSCH on the CG PUSCH TOs when data arrives in the UL data buffer. The UE may indicate the unused CG PUSCH TOs that the UE is not planning to use for UL data transmission in UTO-UCI so that the network may reallocate these resources to other UEs.
[0081] As used herein, the term “collide” may refer to an overlap in the time domain. As used herein, the term “transient period” may refer to a specified period of time (e.g., in one or more symbols) before a start (e.g., a first) of an SSB or a Tx / Rx switch or a specified period of time (e.g., in one or more symbols) after an end (e.g., a last symbol) of an SSB or a Tx / Rx switch. As used herein, the term “invalid CG PUSCH occasion” may refer to a CG PUSCH occasion that is configured by the network but not valid for the UE to transmit uplink data due to the CG PUSCH occasion being colliding with another type of resource, such as an SSB or a transient period associated with the SSB. As used herein, the term “usage indication” may refer to an indication (e.g., in the form of a bitmap, a codepoint, an information element (IE) , or the like) , that may be used to indicate whether a CG PUSCH occasion would be used or not used. If the UE would transmit uplink data in the CG PUSCH occasion, the CG PUSCH occasion would be used and the UE may indicate (e.g., in an usage indication in the UTO-UCI) that the CG PUSCH occasion may be used. If the UE do not have uplink data to transmit in the CG PUSCH occasion, the CG PUSCH occasion would be not used and the UE may indicate (e.g., in an usage indication in the UTO-UCI) that the CG PUSCH occasion may be not used (which may also be referred to as “non-usage” ) . As used herein, the term “Tx / Rx switch” may refer to a switch from Tx to Rx or from Rx to Tx for a half-duplex (HD) UE that is not capable of simultaneous transmissions and receptions on a serving cell in the paired spectrum. There may be an non-zero dynamic switching time from Rx to Tx or from Tx to Rx.
[0082] FIG. 4 is a diagram 400 illustrating example CG PUSCH occasions, in accordance with various aspects of the present disclosure. As illustrated in FIG. 4, multiple CG PUSCH TOs, including PUSCH TO 0 404A, PUSCH TO 1 404B, PUSCH TO 2 404C, PUSCH TO 3 404D are allocated in a CG period 402. A start of the CG period 402 may be aligned with a data (e.g., AR UL video) generation cycle. In some aspects, the configured CG PUSCH TOs may be consecutive in time. In some aspects, the configured CG PUSCH TOs may not be consecutive in time.
[0083] The network may configure the UE to send UTO-UCI to indicate whether the UE uses each of the configured CG PUSCH TOs. The UTO-UCI may be sent in every transmitted PUSCH (every CG PUSCH TO that the UE transmits UL data) of the CG. FIG. 5 is a diagram 500 illustrating example CG PUSCH occasions and UTO-UCI, in accordance with various aspects of the present disclosure. As illustrated in FIG. 5, there may be multiple CG PUSCH TOs, including PUSCH TO 0 504A, PUSCH TO 1 504B, PUSCH TO 2 504C, and PUSCH TO 3 504D. The UE may transmit UL data in the PUSCH TO 0 504A, the PUSCH TO 1 504B, and the PUSCH TO 2 504C, which may each then include a respective UTO-UCI indicating usage. For example, the PUSCH TO 0 504A may include UTO-UCI 514A, the PUSCH TO 1 504B may include UTO-UCI 514B, and the PUSCH TO 2 504C may include UTO-UCI 514C. Because the UE does not transmit UL data in the PUSCH TO 3 504D, the UE would not include UTO-UCI in the PUSCH TO 3 504D. In some aspects, each of the UTO-UCI 514A, the UTO-UCI 514B, and the UTO-UCI 514C, may indicate whether the UE would use the subsequent configured CG PUSCH TOs. For example, the UTO-UCI 514A may indicate whether the UE would use the PUSCH TO 1 504B, the PUSCH TO 2 504C, and the PUSCH TO 3 504D. The UTO-UCI 514B may indicate whether the UE would use the PUSCH TO 2 504C and the PUSCH TO 3 504D. The UTO-UCI 514C may indicate whether the UE would use the PUSCH TO 3 504D.
[0084] Among configured CG PUSCH TOs, there may some TOs that would collide (e.g., overlap in time and / or frequency) with other resources or signals. In some aspects, the UE may determine that the TOs are invalid CG PUSCH TO (s) and not available for use by the UE to transmit PUSCH. As one example, for the unpaired spectrum (e.g., for time division duplexing (TDD) ) , a CG PUSCH TO may be considered as invalid if it collides with DL symbol (s) indicated by a semi-static TDD uplink and downlink configuration (e.g., which may be indicated in parameters based on tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) or symbol (s) of an SS / PBCH block with index provided by an SSB configuration (e.g., ssb-PositionsInBurst that informs the UE about the SSBs being transmitted and the time domain locations of the SSB being transmitted) . The collision may also be considered to occur based on a time period between CG PUSCH TO and SSBs for inter-cell multi-TRP.
[0085] Aspects presented herein provide for more efficient signaling by having a UE consider dynamic collision and dynamic cancellation of CG PUSCH for determining whether a CG PUSCH TO is invalid. Aspects presented herein avoid having the UE use invalid CG PUSCH TOs in automatic repeat request identifier (HARQ-ID) determination for CG PUSCH TOs and UTO-UCI indication for unused CG PUSCH TOs. Aspects presented herein provide for more efficient HARQ management by having the UE avoid determining a HARQ-ID for invalid CG PUSCH TOs and more efficient signaling of UTO-UCI by excluding an indication regarding whether an invalid CG PUSCH TO is used or not in the UTO-UCI. In some wireless communication systems, a UE may determine HARQ-ID for the first configured CG PUSCH TO (regardless of whether it is valid or not) within a multi-PUSCH CGperiod and determine HARQ-ID for subsequent valid CG PUSCH occasions within the CG period. In some aspects, the UE may not indicate whether invalid CG PUSCH occasion (s) are used or not used in the UTO-UCI. Aspects provided herein may enable a UE to refrain from determining HARQ-ID for a CG PUSCH TO and refrain from indicating whether the CG PUSCH TO is used or not used in the UTO-UCI when the CG PUSCH TO collides with a transient period of an SSB so that computational complexity at the UE and the signaling overhead in the wireless communication system may be reduced. Invalid CG PUSCH TOs may be excluded from HARQ ID determination and UTO-UCI for more efficient HARQ ID management and reducing UTO-UCI payload size.
[0086] In addition to higher capability devices, wireless communication may support reduced capability (RedCap) devices (may otherwise be referred as reduced capability UE or RedCap UE) . Among others, examples of higher capability devices include premium smartphones, V2X devices, URLLC devices, eMBB devices, etc. Among other examples, RedCap devices may include wearables, industrial wireless sensor networks (IWSN) , surveillance cameras, low-end smartphones, etc. For example, NR communication systems may support both higher capability devices and reduced capability devices. A RedCap UE may be referred to as an NR light device, a low-tier device, a lower tier device, etc. Reduced capability UEs may communicate based on various types of wireless communication. For example, smart wearables may transmit or receive communication based on low power wide area (LPWA) / mMTC, relaxed IoT devices may transmit or receive communication based on URLLC, sensors / cameras may transmit or receive communication based on eMBB, etc.
[0087] In some examples, a reduced capability UE may have reduced transmission bandwidth or reception bandwidth than other UEs. For instance, a reduced capability UE may have a smaller bandwidth of 5 MHz or 20 MHz BWP in FR1 or 100 MHz in FR2. In some aspects, the reduced capability UE may have an operating bandwidth between 5 MHz and 20MHz (such as 20 MHz) for both transmission and reception, in contrast to other UEs which may have a bandwidth of up to 100 MHz or more than 100 MHz. As a further example, a reduced capability UE may have a reduced number of reception antennas (e.g., 2 reception antennas) in comparison to other UEs that may have a larger number of reception antennas. For instance, a reduced capability UE may have a single receive antenna, or two receive antennas, and may experience a lower equivalent receive signal to noise ratio (SNR) in comparison to higher capability UEs that may have additional antennas. Reduced capability UEs may also have reduced computational complexity than other UEs. As reduced capability UEs may have 20 MHz BWP, if the number of reduced capability UEs served by a base station is large, these UEs may be assigned with different BWPs so that the cell traffic load may be balanced in a cell with a larger bandwidth. Reduced capability UEs may also have a reduced bandwidth for PDSCH or PUSCH and reduced peak data rate for FR1. A particular example of a reduced capability UE may be a wearable device for XR applications. Some reduced capability UE (s) may be HD UE (such as type A HD FDD UE that supports HD-FDD and able to perform DL reception in subframes where it does not perform UL transmission) , where the UE is not capable of simultaneous transmissions and receptions on a serving cell in the paired spectrum.
[0088] FIG. 6 is a diagram 600 illustrating example aspects of a transient period, in accordance with various aspects of the present disclosure. The general ON / OFF time mask defines the observation period allowed between transmit OFF and ON power. ON / OFF scenarios include: the beginning or end of discontinuous transmission (DTX) , measurement gap, contiguous, and non-contiguous transmission, or the like. The OFF power measurement period may be in a duration of at least one slot excluding any transient periods, e.g., a period of time between an OFF power measurement period and an ON power period. The ON power may be the mean power over one slot excluding any transient period. As illustrated in FIG. 6, before the UE starts to transmit in a start slot 602, after the power reaches a particular level, it may be an end of OFF power at 604, after a transient period 608, the power may reach another particular level, and it may be a strat of ON power at 606. Similarly, after an UE transmits in an end slot 612, after the power reaches a particular level, it may be an end of ON power at 614, after a transient period 618, the power may reach another particular level, and it may be a start of OFF power 616. The period in which the power level is above OFF power but below ON power may be considered to be the transient period.
[0089] In some wireless communication systems, as an example, collision handling for HD-FDD reduced capability may be based on various types of configurations, such as: (1) dedicated RRC configuration for DL for PDCCH in UE specific search space (USS) , semi-persistent scheduling (SPS) PDSCH, CSI-RS, or positioning reference signal (PRS) , (2) dedicated RRC configuration for UL for CG PUSCH, PRACH and message A for contention free random access (CFRA) , SRS, or PUCCH, (3) dynamically scheduled UL for PUCCH (including HARQ feedback for message 4 or message B in RACH procedure) , PUSCH, SRS, PDCCH ordered PRACH, (4) cell specific DL for SSB or PDCCH in Type-0 / 0A / 1 / 2 common search space (CSS) , or (5) cell specific UL for valid PRACH occasion (e.g., in message 1 or message A preamble) , and valid message A PUSCH occasion. For collisions between signaling based on a dedicated RRC configuration for UL and DL SSB, the DL SSB may be prioritized. For collision between dynamically scheduled signaling for UL and DL SSB, the DL SSB may be prioritized. For HD-FDD RedCap UE, many UL / DL collision handling rules may be defined such that the UE would transmit or receive at a time, but not both transmit / receive at a same time. CG PUSCH may be based on dedicated RRC configuration for UL. Therefore, the UE may not transmit CG PUSCH when the CG PUSCH collides with dynamically scheduled DL signaling or SSB.
[0090] In some wireless communication systems, the invalid CG PUSCH may include semi-static conditions for TDD in an unpaired spectrum, but CG PUSCH TO overlapping with a transient period is not considered to be invalid. Aspects provided herein may further include CG PUSCH TO overlapping with a transient period to be invalid CG PUSCH TO to reduce computational complexity at the UE and reduce signaling overhead for a UTO-UCI transmitted by the UE.
[0091] In some aspects, for HD-FDD UEs, in paired spectrum and SUL band, a CG PUSCH TO may be considered as invalid if the CG PUSCH TO collides (e.g., in time) with the SSB or a transient period before or after the SSB, e.g., a threshold amount of time prior to or after an SSB. In some aspects, HARQ ID is determined for the first configured CG PUSCH TO (valid or invalid) within the multi-PUSCH CG period and the subsequent valid CG PUSCH occasions within the CG period, but not determined for invalid CG PUSCH TO (s) (e.g., that collides with the SSB or the transient period) that are not the first configured CG PUSCH TO. In some aspects, the UTO-UCI do not indicate whether invalid CG PUSCH TO (s) that collides (e.g., in time) with the SSB or a transient period before or after the SSB is used or not used. For example, if a HD UE is configured with a CG PUSCH TO and the HD UE is indicated presence of SS / PBCH blocks within the active DL BWP by a SSB configuration (e.g., ssb-PositionsInBurst in SIB1 or in ServingCellConfigCommon or by NonCellDefiningSSB) , the HD UE would not transmit PUSCH in the CG PUSCH TO.In some aspects, if a last symbol of the CG PUSCH TO would not be at least a specific quantity of symbols (e.g., based on NTx-Rx·Tc, where Tc is a basic time unit and NTx-Rx is a minimum time from reception to transmission) prior to a first symbol of the next earliest SS / PBCH block or if a first symbol of the CG PUSCH TO would not be at least a specific quantity of symbols (e.g., based on NRx-Tx·Tc, where Tc is a basic time unit and NRx-Tx is a minimum time from reception to transmission) after a last symbol of the previous latest SS / PBCH block. In some aspects, for TDD, a CG PUSCH TO may be skipped if there is a collision with non-cell defining (NCD) SSBs. In some aspects, for TDD in unpaired spectrum, a CG PUSCH TO is considered as invalid if it collides with the non-cell-defining SSB.
[0092] FIG. 7 is a diagram 700 illustrating example communications between a network entity 704 and a UE 702, in accordance with various aspects of the present disclosure. As illustrated in FIG. 7, the UE 702 may receive, from the network entity 704, a CG PUSCH configuration 706 configuring a set of CG PUSCH TOs and an SSB configuration 708 configuring a set of SSBs. When the UE 702 has uplink data to transmit, the UE 702 may transmit the uplink data in one or more valid CG PUSCH TOs of the set of CG PUSCH TOs. The UE 702 may transmit UTO-UCI 710 to indicate whether one or more valid CG PUSCH TOs will be used (used for transmitting data) or not used (not used for transmitting data) and the UTO-UCI 710 may be multiplexed in a valid and used CG PUSCH TO. In some aspects, the UE 702 may not include (e.g., may skip or exclude) a usage indication that indicates whether invalid CG PUSCH TO is used or not used in the UTO-UCI 710. In some aspects, based on the usage indication in the UTO-UCI 710, the network entity 704 may reallocate unused CG PUSCH TOs to other UEs. In some aspects, a valid CG PUSCH TO may be a CG PUSCH TO that does not collide in time with (1) SSB, (2) transient period associated with SSB, (3) transient period associated with Tx / Rx switch, or (4) one or more particular types of DL symbols. In some aspects, the UE 702 may determine, at 712, HARQ-ID for a first configured CG PUSCH TO (regardless of whether it’s valid or invalid) and subsequent CG PUSCH TO (s) that are valid and may refrain from determining HARQ-ID for subsequent CG PUSCH TO (s) that are invalid. As illustrated at 714, the network entity 704 may receive the UTO-UCI from the UE and may interpret the UTO-UCI based on a HARQ-ID determined in the same manner as determined by the UE 702 at 712.
[0093] FIG. 8 is a diagram 800 illustrating example CG PUSCH occasions, UTO-UCI, and HARQ-ID, in accordance with various aspects of the present disclosure. As illustrated in FIG. 8, within a particular data cycle 802, there may be four PUSCH TOs configured, including CG PUSCH TO 0 804A, CG PUSCH TO 1 804B, CG PUSCH TO 2 804C, and CG PUSCH TO 3 804D. Based on an SSB configuration, there may be two SSBs configured, including SSB 806A and SSB 806B, which may be each associated with a transient period before the SSB and a transient period after the SSB. Because the CG PUSCH TO 0 804A and the CG PUSCH TO 2 804C do not collide with any of the SSB or the transient period, the CG PUSCH TO 0 804A and the CG PUSCH TO 2 804C may be valid and the UE may include usage indication for the CG PUSCH TO 0 804A and the CG PUSCH TO 2 804C in the UTO-UCI (e.g., which may be multiplexed with the CG PUSCH TO 0 804A) to indicate whether the valid CG PUSCH TO (s) are used or not used. The UE may determine HARQ-ID for the CG PUSCH TO 0 804A and the CG PUSCH TO 2 804C because the CG PUSCH TO 0 804A and the CG PUSCH TO 2 804C are valid. Because the CG PUSCH TO 1 804B collides with SSB 806A and the CG PUSCH TO 3 804D collides with the SSB 806B or the transient period, the CG PUSCH TO 1 804B or the CG PUSCH TO 3 804D are invalid. In some aspects, the UE may not include usage indication for the CG PUSCH TO 1 804B or the CG PUSCH TO 3 804D in the UTO-UCI to indicate whether the invalid CG PUSCH TO (s) are used or not used. In some aspects, the UE may not determine HARQ-ID for the CG PUSCH TO 1 804B or the CG PUSCH TO 3 804D.
[0094] FIG. 9 is a diagram 900 illustrating example CG PUSCH occasions, UTO-UCI, and HARQ-ID, in accordance with various aspects of the present disclosure. As illustrated in FIG. 9, within a particular data cycle 902, there may be four PUSCH TOs configured, including CG PUSCH TO 0 904A, CG PUSCH TO 1 904B, CG PUSCH TO 2 904C, and CG PUSCH TO 3 904D. Based on an SSB configuration, there may be two SSBs configured, including SSB 906A and SSB 906B, which may be each associated with a transient period before the SSB and a transient period after the SSB. Because the CG PUSCH TO 1 904B and the CG PUSCH TO 3 904D do not collide with any of the SSB or the transient period, the CG PUSCH TO 1 904B and the CG PUSCH TO 3 904D may be valid and the UE may include usage indication for the CG PUSCH TO 1 904B and the CG PUSCH TO 3 904D in the UTO-UCI (e.g., which may be multiplexed with the CG PUSCH TO 1 804B) to indicate whether the valid CG PUSCH TO (s) are used or not used. The UE may determine HARQ-ID for the CG PUSCH TO 1 904B and the CG PUSCH TO 3 904D because the CG PUSCH TO 1 904B and the CG PUSCH TO 3 904D are valid. Because the CG PUSCH TO 0 904A collides with SSB 906A and the CG PUSCH TO 2 904C collides with the SSB 906B or the transient period, the CG PUSCH TO 0 904A and the CG PUSCH TO 2 904C are invalid. In some aspects, the UE may not include usage indication for the CG PUSCH TO 0 904A and the CG PUSCH TO 2 904C in the UTO-UCI to indicate whether the invalid CG PUSCH TO (s) are used or not used. In some aspects, the UE may not determine HARQ-ID for the CG PUSCH TO 2 904C. In some aspects, the UE may still determine HARQ-ID for the CG PUSCH TO 0 904A due to the CG PUSCH TO 0 904A being the first configured CG PUSCH in the data cycle 902.
[0095] In some aspects, to determine HARQ-ID, the UE may increment for valid CG PUSCH TOs after the first configured CG PUSCH TO in the CG period and the first configured CG PUSCH TO may be assigned with HARQ-ID equal to 0 or configured by network.
[0096] In some aspects, if the UE is provided a configuration of the number of bits used for UTO-UCI (e.g., which may be referred to as “nrof_UTO_UCI” ) with value equal to OUTO-UCI in configuredGrantConfig of a CG-PUSCH configuration, the UE multiplexes UTO-UCI represented by a bitmap of OUTO-UCI bits in each CG-PUSCH transmission for the CG-PUSCH configuration.
[0097] In some aspects, the OUTO-UCI bits of UTO-UCI, have a one-to-one mapping to OUTO-UCI subsequent CG-PUSCH TOs in ascending order of start time. For unpaired spectrum operation, the OUTO-UCI subsequent CG-PUSCH TOs exclude invalid ones where a UE does not transmit a PUSCH due to collision of the PUSCH with the DL symbol (s) indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated if provided, or a symbol (s) of an SS / PBCH block with index provided by ssb-PositionsInBurst based on the procedures in or by NonCellDefiningSSB. For HD-UE in paired spectrum and SUL band, the OUTO-UCI subsequent CG-PUSCH TOs exclude invalid ones where a UE does not transmit a PUSCH due to collision of the PUSCH with a symbol (s) of an SS / PBCH block with index provided by ssb-PositionsInBurst in SIB1 or in ServingCellConfigCommon or by NonCellDefiningSSB, or if a last symbol of the CG-PUSCH TO would not be at least NTx-Rx·Tc prior to a first symbol of the next earliest SS / PBCH block or if a first symbol of the CG-PUSCH TO would not be at least NRx-Tx·Tc after a last symbol of the previous latest SS / PBCH block. A bit value of ‘0’ indicates that the UE may transmit CG-PUSCH, and a bit value of ‘1’ indicates that the UE will not transmit CG-PUSCH, in a corresponding CG-PUSCH TO. When the UE indicates by UTO- UCI a value of ‘1’ for a CG-PUSCH TO, the UE continues to indicate the value of ‘1’ for the CG-PUSCH TO by UTO-UCI multiplexed in subsequent CG-PUSCH transmissions, and the UE does not transmit CG-PUSCH in the CG-PUSCH TO.
[0098] In some aspects, when the number of slots for PUSCH transmission in a multi-PUSCH CG period nrofSlots_InCGperiod is configured for Type 1 CG or Type 2 CG, HARQ process ID for the Kth (1 < K ≤ nrofSlots_InCGperiod) valid CG PUSCH TO is determined, excluding invalid CG PUSCH TOs that are not transmitted due to collision with the DL symbol (s) indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated if provided, or a symbol (s) of an SS / PBCH block with index provided by ssb-PositionsInBurst or by NonCellDefiningSSB, or for HD-UE in paired spectrum and SUL band, due to the collision with a symbol (s) of an SS / PBCH block with index provided by ssb-PositionsInBurst in SIB1 or in ServingCellConfigCommon or by NonCellDefiningSSB, or if a last symbol of the CG-PUSCH TO would not be at least NTx-Rx·Tc prior to a first symbol of the next earliest SS / PBCH block or if a first symbol of the CG-PUSCH TO would not be at least NRx-Tx·Tc after a last symbol of the previous latest SS / PBCH block.
[0099] FIG. 10 is a flowchart 1000 of a method of wireless communication. The method may be performed by a UE (e.g., the UE 104, the UE 702; the apparatus 1304) . The method may enable a UE to reduce signaling overhead and reduce computational complexity at a modem of the UE by not indicating usage for invalid CG PUSCH occasions and not determining HARQ-ID for subsequent invalid CG PUSCH occasions after the first CG PUSCH occasion (which may be valid or invalid) .
[0100] At 1002, the UE may receive, from a network entity, a configuration of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. For example, the UE 702 may receive, from a network entity 704, a configuration (e.g., 706) of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. In some aspects, 1002 may be performed by CG component 198.
[0101] At 1004, the UE may transmit, to the network entity, unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB. For example, the UE 702 may transmit, to the network entity 704, unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) (e.g., 710) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB. In some aspects, 1004 may be performed by CG component 198.
[0102] FIG. 11 is a flowchart 1100 of a method of wireless communication. The method may be performed by a UE (e.g., the UE 104, the UE 702; the apparatus 1304) . The method may enable a UE to reduce signaling overhead and reduce computational complexity at a modem of the UE by not indicating usage for invalid CG PUSCH occasions and not determining HARQ-ID for subsequent invalid CG PUSCH occasions after the first CG PUSCH occasion (which may be valid or invalid) .
[0103] At 1102, the UE may receive, from a network entity, a configuration of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. For example, the UE 702 may receive, from a network entity 704, a configuration (e.g., 706) of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. In some aspects, 1102 may be performed by CG component 198.
[0104] At 1104, the UE may transmit, to the network entity, unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB. For example, the UE 702 may transmit, to the network entity 704, unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) (e.g., 710) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB. In some aspects, 1104 may be performed by CG component 198. In some aspects, the transient period before or after the SSB may be the same as a transient period for Rx and Tx switching. In some aspects, the transient period before or after the SSB may be different (e.g., longer or shorter) from a transient period for Rx and Tx switching.
[0105] At 1106, the UE may refrain from indicating a usage associated with the one or more invalid CG PUSCH occasions that collides with the SSB or the transient period before or after the SSB in the UTO-UCI. For example, the UE 702 may refrain from indicating a usage associated with the one or more invalid CG PUSCH occasions that collides with the SSB or the transient period before or after the SSB in the UTO-UCI. In some aspects, 1106 may be performed by CG component 198.
[0106] At 1108, the UE may refrain from indicating a usage associated with the one or more invalid CG PUSCH occasions that collides with the SSB or the transient period before or after the SSB in the UTO-UCI. For example, the UE 702 may refrain from determining a HARQ-ID associated with the one or more invalid CG PUSCH occasions that collides with the SSB or the transient period before or after the SSB, where the one or more invalid CG PUSCH occasions are subsequent CG PUSCH occasions after a first configured CG PUSCH occasions of the set of CG PUSCH occasions.
[0107] In some aspects, the transient period includes a first quantity of symbols before a first symbol of a next earliest SSB or a second quantity of symbols after a last symbol of a previous latest SSB. In some aspects, the one or more invalid CG PUSCH occasions are considered to be invalid when the one or more invalid CG PUSCH occasions collides with the SSB or the transient period before or after the SSB and when the UE is operating in a half-duplex frequency division duplex (HD-FDD) mode. In some aspects, the one or more invalid CG PUSCH occasions are considered to be invalid when the one or more invalid CG PUSCH occasions collides with the SSB when the UE is operating in a time division duplex (TDD) mode and the SSB is a non-cell defining SSB (NCD-SSB) . In some aspects, the TDD mode is associated with an unpaired spectrum. In some aspects, the one or more invalid CG PUSCH occasions includes an invalid CG PUSCH occasion that collides with a transient period for transmission (Tx) or reception (Rx) switching. In some aspects, the UTO-UCI does not indicate a usage associated with the one or more invalid CG PUSCH occasions that collides with the SSB or the transient period before or after the SSB in the UTO-UCI. In some aspects, the at least one HARQ-ID is associated with one or more valid CG PUSCH occasion of the set of CG PUSCH occasions or a first configured CG PUSCH occasion of the set of CG PUSCH occasions, the first configured CG PUSCH occasion being valid or invalid.
[0108] FIG. 12 is a flowchart 1200 of a method of wireless communication. The method may be performed by a network entity (e.g., the base station 102, the network entity 1302, the network entity 1402) .
[0109] At 1202, the network entity may transmit, for a user equipment (UE) , a configuration of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. For example, the network entity 704 may transmit, for a user equipment (UE) 702, a configuration (e.g., 706) of a set of configured grant (CG) physical uplink shared channel (PUSCH) occasions. In some aspects, 1202 may be performed by CG component 199.
[0110] At 1204, the network entity may receive unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) (e.g., 710) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB. For example, the network entity [ [may receive unused transmission occasion (s) indicated by uplink control information (UCI) (UTO-UCI) including a set of usage indications indicating at least one CG PUSCH occasion of the set of CG PUSCH occasions or determine at least one hybrid automatic repeat request identifier (HARQ-ID) associated with the at least one CG PUSCH occasion of the set of CG PUSCH occasions, the at least one CG PUSCH occasion excluding one or more invalid CG PUSCH occasions that collides with a synchronization signal block (SSB) or a transient period before or after the SSB.

[0116] It is understood that the specific order or hierarchy of blocks in the processes / flowcharts disclosed is an illustration of example approaches. Based upon design preferences, it is understood that the specific order or hierarchy of blocks in the processes / flowcharts may be rearranged. Further, some blocks may be combined or omitted.

[0117] The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims. Reference to an element in the singular does not mean “one and only one” unless specifically so stated, but rather “one or more. ” Terms such as “if, ” “when, ” and “while” do not imply an immediate temporal relationship or reaction. That is, these phrases, e.g., “when, ” do not imply an immediate action in response to or during the occurrence of an action, but simply imply that if a condition is met then an action will occur, but without requiring a specific or immediate time constraint for the action to occur. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration. ” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects. Unless specifically stated otherwise, the term “some” refers to one or more. Combinations such as “at least one of A, B, or C, ” “one or more of A, B, or C, ” “at least one of A, B, and C, ” “one or more of A, B, and C, ” and “A, B, C, or any combination thereof” include any combination of A, B, and / or C, and may include multiples of A, multiples of B, or multiples of C. Specifically, combinations such as “at least one of A, B, or C, ” “one or more of A, B, or C, ” “at least one of A, B, and C, ” “one or more of A, B, and C, ” and “A, B, C, or any combination thereof” may be A only, B only, C only, A and B, A and C, B and C, or A and B and C, where any such combinations may contain one or more member or members of A, B, or C. Sets should be interpreted as a set of elements where the elements number one or more. Accordingly, for a set of X, X would include one or more elements. When at least one processor is configured to perform a set of functions, the at least one processor, individually or in any combination, is configured to perform the set of functions. Accordingly, each processor of the at least one processor may be configured to perform a particular subset of the set of functions, where the subset is the full set, a proper subset of the set, or an empty subset of the set. If a first apparatus receives data from or transmits data to a second apparatus, the data may be received / transmitted directly between the first and second apparatuses, or indirectly between the first and second apparatuses through a set of apparatuses. A device configured to “output” data, such as a transmission, signal, or message, may transmit the data, for example with a transceiver, or may send the data to a device that transmits the data. A device configured to “obtain” data, such as a transmission, signal, or message, may receive, for example with a transceiver, or may obtain the data from a device that receives the data. Information stored in a memory includes instructions and / or data. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are encompassed by the claims. Moreover, nothing disclosed herein is dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. The words “module, ” “mechanism, ” “element, ” “device, ” and the like may not be a substitute for the word “means. ” As such, no claim element is to be construed as a means plus function unless the element is expressly recited using the phrase “means for. ”
[0118] As used herein, the phrase “based on” shall not be construed as a reference to a closed set of information, one or more conditions, one or more factors, or the like. In other words, the phrase “based on A” (where “A” may be information, a condition, a factor, or the like) shall be construed as “based at least on A” unless specifically recited differently.
