Description

UPLINK-BASED JOINT HANDLING OF CROSS-COMPONENT CARRIER SPS AND CGS

TECHNICAL FIELD

The present disclosure relates generally to communication systems, and more particularly, to wireless communications utilizing uplink signaling for configuration handling.

INTRODUCTION

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.

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.

DETAILED DESCRIPTION

Wireless communication networks, such as a 5G NR network, may enable traffic flows with specific characteristics. As an example, extended reality (XR) traffic for UL and DL may have characteristics such as application layer attributes, short timeframes for exchange where longer latency for traffic flows may reduce a user experience with an XR application or device, etc. Additionally, XR traffic bursts are periodic but may include some time jitter in their arrival, and the XR packet sizes, and the number of packets, for certain bursts may be variable. That is, XR service characteristics such as periodicity, multiple flows, jitter, latency, reliability, etc. , may affect power usage and operations at base stations and other devices on a wireless communication network.

A normal dynamic grant (DG) may be used to handle XR traffic, but this may include additional signaling (e.g., physical downlink control channel (PDCCH) ) and additional power consumption (e.g. , PDCCH decoding) to allocate resources for the traffic. Semi-persistent scheduling (SPS) and configured grant (CG) operations may be utilized as candidates for periodic XR traffic, however, because the number and sizes of packet per XR burst or period may not be constant, and at some instances, the network may not know beforehand the XR traffic details. Resources provided by a SPS and/or CG occasion may either be smaller or larger, than the data to be transmitted for a given XR burst. In some aspects, SPS and/or CG occasions for XR bursts may waste resources (e.g. , if more resources are allocated than the amount of XR data to be transmitted) . In some aspects, SPS and/or CG occasions for XR bursts may cause delays (e.g., if fewer resources are allocated than the XR data to be transmitted) . In some aspects, SPS and/or CG occasions for XR bursts may lead to unnecessary base station beam direction reservation for UL data (e.g., if more resources than XR data are allocated) . While wireless communication networks, may support dynamic indications of unused an CG physical uplink shared channel (PUSCH) occasion (s) based on uplink control information (UCI) from the UE and multiple CG PUSCH transmission occasions in a period of a single CG PUSCH configuration, as noted above, this may include involve additional signaling and power for encoding /decoding the dynamic indications.

Various aspects presented herein relate generally to wireless communications systems and user equipment utilization of UL transmissions. Some aspects more specifically relate to UL-based joint handling of cross-CC SPS and CGs. In some examples, a UE may receive multiple configurations for a CG configuration (s) for UL data signaling and/or a SPS configuration (s) for DL data signaling, and transmit a single control information message associated with the multiple configurations for the CG configuration (s) and/or the SPS configuration (s) .

Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by providing a single control information message for UL-based joint handling of cross-CC SPS and CGs, the described techniques can be used to reduce, or more efficiently use, processing resources for coding /decoding as well as UL/DL data signaling resources through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions. Additionally, when a UE provides a single control information message across one or more CCs for multiple SPS and/or CG occasions, the network (e.g., a base station) is efficiently made aware of traffic characteristics (e.g., periodicity, multiple flows, jitter, latency, reliability, etc. , in XR or other types of traffic) , and the network is thus enabled to further configure signaling and traffic with the UE, as indicated, for the described power and signaling efficiencies.

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.

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.

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. 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.

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.

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.

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.

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.g a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) .

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.

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.

Each of the units, i.e.g 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.

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.g Central Unit –User Plane (CU-UP) ) , control plane functionality (i.e.g 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.

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.

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.

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.

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.

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) .

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) .

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, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

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.

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.

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.

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.

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.

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) .

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.

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.

Referring again to FIG. 1, in certain aspects, the UE 104 may have a joint handling component 198 ( “component 198” ) that may be configured to receive multiple configurations for at least one of a configured grant (CG) configuration for uplink (UL) data signaling or a semi-persistent scheduling (SPS) configuration for downlink (DL) data signaling. The component 198 may be configured to transmit a single control information message for the multiple configurations for the at least one of the CG configuration or the SPS configuration. In some aspects, the component 198 may also be configured to receive, via RRC signaling, at least one parameter respectively associated with the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC, and to activate or deactivate the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC. In some aspects, the component 198 may also be configured to jointly code the single control information message across the first CC with a first portion of the single control information message and a second CC of the at least one additional CC with a second portion of the single control information message. In some aspects, the component 198 may also be configured to transmit the UL data signaling or receive the DL data signaling via at least one CC based on a configured time delay from the single control information message for the at least one of the CG configuration or the SPS configuration, where the configured time delay is associated with at least one of a number of CCs of the at least one CC or a respective frequency of the at least one CC. In some aspects, the component 198 may also be configured to receive, via RRC signaling, a set of one or more CCs, where each of the one or more CCs in the set is associated with an index for a respective combination of the at least one of the CG configuration or the SPS configuration, and to select at least one of the one or more CCs to transmit the single control information message based on the at least one of the CG configuration or the SPS configuration and a corresponding index. In certain aspects, the base station 102 may have a joint handling component 199 ( “component 199” ) that may be configured to transmit multiple configurations for at least one of a CG configuration for UL data signaling or a SPS configuration for DL data signaling. The component 199 may be configured to receive a single control information message for the multiple configurations for the at least one of the CG configuration or the SPS configuration. In some aspects, the component 199 may also be configured to transmit, via RRC signaling, at least one parameter respectively associated with the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC, where the at least one parameter is associated with an activation or a deactivation for the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC. In some aspects, the component 199 may also be configured to receive the UL data signaling or transmit the DL data signaling via at least one component carrier (CC) based on a configured time delay from the single control information message for the at least one of the CG configuration or the SPS configuration, where the configured time delay is associated with at least one of a number of CCs of the at least one CC or a respective frequency of the at least one CC. In some aspects, the component 199 may also be configured to transmit, via RRC signaling, a set of one or more CCs, where each of the one or more CCs in the set is associated with an index for a respective combination of the at least one of the CG configuration or the SPS configuration. That is, aspects provide for UL-based joint handling of cross-CC SPS and CG occasions that enables a UE to inform a network node (e.g., a base station) for characteristics of certain traffic and reduces processing for coding /decoding and utilization of signaling resources (both of which reduce power consumption) through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions.

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.

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.

Table 1: Numerology, SCS, and CP

For normal CP (14 symbols/slot) , different numerologies μ0 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 2^μ slots/subframe. The subcarrier spacing may be equal to 2^μ*15kHz, where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15kHz and the numerology μ=4 has a subcarrier spacing of 240kHz. 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 60kHz, 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) .

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.

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) .

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.

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.

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.g 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.

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.

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.

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.

The controller/processor 359 can be associated with a memory 360 that stores program codes and data. The 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.

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.

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.

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.

The controller/processor 375 can be associated with a memory 376 that stores program codes and data. The 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.

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 the joint handling component 198 of FIG. 1. 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 the joint handling component 199 of FIG. 1.

Traffic flows may have various characteristics in wireless communication networks, e.g. , including layer attributes, timeframes for latency, etc. As an example, XR traffic for UL and DL, may have characteristics such as application layer attributes, short timeframes for exchange where longer latency for traffic flows may reduce a user experience with an application or device, etc. Additionally, such traffic bursts may be periodic but may include some time jitter in their arrival, and the packet sizes, and the number of packets, for certain bursts may be variable. That is, service characteristics such as periodicity, multiple flows, jitter, latency, reliability, etc. , may affect power usage and operations at base stations and other devices on a wireless communication network.

A normal dynamic grant (DG) may be provided to allocate resources for XR traffic, but this may include additional signaling (e.g., physical downlink control channel (PDCCH) ) and additional power consumption (e.g., PDCCH decoding) to indicate or schedule the allocated resources. Semi-persistent scheduling (SPS) and configured grant (CG) operations may be utilized as candidates for periodic XR traffic. However, the number and sizes of packet per XR burst or period may not be constant, and at some instances, the network may not know beforehand the XR traffic details. An SPS and/or CG occasion may either be smaller or larger in terms of resources than for the data to be transmitted in a given XR burst. As a result, a regular application of SPS and/or CG occasions for XR bursts may waste resource (e.g., if more resources than XR data are allocated) , may cause delays (e.g., if fewer resources than XR data are allocated) , may lead to unnecessary base station beam direction reservation for UL data (e.g., if more resources than XR data are allocated) , etc. While wireless communication networks, such as 5G NR networks, may support dynamic indications of unused an CG physical uplink shared channel (PUSCH) occasion (s) based on uplink control information (UCI) from the UE and multiple CG PUSCH transmission occasions in a period of a single CG PUSCH configuration, as noted above, this may include an expense of additional signaling and power for encoding /decoding. Although examples are provided for XR traffic, the concepts presented herein may also be applied to other types of traffic.

Aspects described herein for UL-based joint handling of cross-CC SPS and CGs may provide enhancements to continuous discontinuous reception (C-DRX) and PDCCH monitoring for power savings, as well as enhancing SPS /CG and dynamic scheduling / grants for traffic capacity, and may also improve and/or reduce the use of processing resources for coding /decoding as well as UL /DL data signaling resources through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions. Aspects presented herein improve the efficient use of wireless resources and power resources for transmission of signaling while also providing for more efficient use of allocated wireless resources while providing resources that allow for variations in data traffic. For example, when a UE provides a single control information message across one or more CCs for multiple SPS and/or CG occasions, the network (e.g., a base station) is efficiently made aware of traffic characteristics (e.g., periodicity, multiple flows, jitter, latency, reliability, etc. , in XR) , and the network is thus enabled to further configure signaling and traffic with the UE, as indicated, for the described power and signaling efficiencies.

While various aspects may be described in the context of XR for descriptive and illustrative purposes, aspects are not so limited and are applicable to other types of applications, traffic, and/or data, as would be understood by persons of skill in the relevant art (s) having the benefit of this disclosure.

FIG. 4 is a diagram 400 illustrating example XR traffic, in various aspects. XR traffic may refer to wireless communications for technologies such as virtual reality (VR) , mixed reality (MR) , and/or augmented reality (AR) . VR may refer to technologies in which a user is immersed in a simulated experience that is similar or different from the real world. A user may interact with a VR system through a VR headset or a multi-projected environment that generates realistic images, sounds, and other sensations that simulate a user’s physical presence in a virtual environment. MR may refer to technologies in which aspects of a virtual environment and a real environment are mixed. AR may refer to technologies in which objects residing in the real world are enhanced via computer-generated perceptual information, sometimes across multiple sensory modalities, such as visual, auditory, haptic, somatosensory, and/or olfactory. An AR system may incorporate a combination of real and virtual worlds, real-time interaction, and accurate three-dimensional registration of virtual objects and real objects. In an example, an AR system may overlay sensory information (e.g., images) onto a natural environment and/or mask real objects from the natural environment. XR traffic may include video data and/or audio data. XR traffic may be transmitted by a base station and received by a UE or the XR traffic may be transmitted by a UE and received by a base station.

XR traffic may arrive in periodic traffic bursts ( “XR traffic bursts” ) . An XR traffic burst may vary in a number of packets per burst and/or a size of each pack in the burst. The diagram 400 illustrates a first XR flow 402 that includes a first XR traffic burst 404 and a second XR traffic burst 406. As illustrated in the diagram 400, the traffic bursts may include different numbers of packets, e.g., the first XR traffic burst 404 being shown with three packets (represented as rectangles in the diagram 400) and the second XR traffic burst 406 being shown with two packets. Furthermore, as illustrated in the diagram 400, the three packets in the first XR traffic burst 404 and the two packets in the second XR traffic burst 406 may vary in size, that is, packets within the first XR traffic burst 404 and the second XR traffic burst 406 may include varying amounts of data.

XR traffic bursts may arrive at non-integer periods (i.e.g in a non-integer cycle) . The periods may be different than an integer number of symbols, slots, etc. In an example, for 60 frames per second (FPS) video data, XR traffic bursts may arrive in 1/60=16.67 ms periods. In another example, for 120 FPS video data, XR traffic bursts may arrive in 1/120 = 8.33 ms periods.

Arrival times of XR traffic may vary. For example, XR traffic bursts may arrive and be available for transmission at a time that is earlier or later than a time at which a UE (or a base station) expects the XR traffic bursts. The variability of the packet arrival relative to the period (e.g., 16.76 ms period, 8.33 ms period, etc. ) may be referred to as “jitter. ” In an example, jitter for XR traffic may range from -4 ms (earlier than expected arrival) to +4 ms (later than expected arrival) . For instance, referring to the first XR flow 402, a UE may expect a first packet of the first XR traffic burst 404 to arrive at time t0, but the first packet of the first XR traffic burst 404 arrives at a time t1, as shown.

XR traffic may include multiple flows that arrive at a UE (or a base station) concurrently with one another (or within a threshold period of time) . For instance, the diagram 400 includes a second XR flow 408. The second XR flow 408 may have different characteristics than the first XR flow 402. For instance, the second XR flow 408 may have XR traffic bursts with different numbers of packets, different sizes of packets, etc. In an example, the first XR flow 402 may include video data and the second XR flow 408 may include audio data for the video data. In another example, the first XR flow 402 may include intra-coded picture frames (I-frames) that include complete images and the second XR flow 408 may include predicted picture frames (P-frames) that include changes from a previous image.

As noted herein, XR traffic may have an associated e2e PDB. If a packet does not arrive within the e2e PDB, a UE (or a base station) may discard the packet. In an example, if a packet corresponding to a video frame of a video does not arrive at a UE within an e2e PDB, the UE may discard the packet, as the video has advanced beyond the frame. However, the RDB at the UE may be unaccounted for in consideration of discarding packets. An example time diagram 450 shows a length of time corresponding to a PDB 454. At a particular point in time 456, the residual delay budget 452 is the remaining portion of the PDB 454.

An XR traffic overall PDB may include a portion to allow for communication delay of data (e2e PDB) between a UE and a computing device, e.g., a server, hosting an application, e.g., for XR, and a portion for additional time after the communication delay before the data is discarded, e.g., residual delay (e.g., RDB) . For instance, the diagram 400 includes a packet delay budget flow 410. Packet delay budget flow 410 illustrates a UE 412, a network entity 414 (e.g., a base station or portion thereof) , and a server 416 that hosts an application 418. In the illustrated aspect, a communication delay 420 is shown as including a RAN portion between the UE 502 and the network entity 414, as well as a CN portion between the network entity 414 and the server 416. The communication delay 420 may apply to both UL and DL communications. Additionally, a residual delay 422 is shown at the UE 412 for DL communications and a residual delay 424 is shown at the server 416 for UL communications. The communication delay 420 and the residual delay 422 may make up an overall PDB for DL XR communications, e.g., DL PDB 426. Likewise, the communication delay 420 and the residual delay 424 may make up an overall PDB for UL XR communications (not shown for illustrative clarity) .

In general, XR traffic may be characterized by relatively high data rates and low latency. The latency in XR traffic may affect the user experience. For instance, XR traffic may have applications in eMBB and URLLC services.

Various aspects may be employed to provide power saving and/or capacity improvement for wireless communication, e.g., including XR traffic. Joint control messaging for scheduling mechanisms such as semi-persistent scheduling (SPS) or a configured grant (CG) may be used to provide a single signaling mechanism for configurations, activations, deactivations, skips, frequency /time shifts, changes to beams, and/or the like, across one or multiple CCs, for such periodic resources for UL or DL communications.

FIG. 5 is a call flow diagram 500 for wireless communications, in various aspects. Call flow diagram 500 illustrates UL-based joint handling of cross-CC SPS and CGs by a UE (e.g., a UE 502) that may communicate with a network node (a base station 504, such as a gNB or other type of base station, by way of example, as shown) . Aspects described for the base station 504 may be performed by the base station in aggregated form and/or by one or more components of the base station 504 in disaggregated form. Additionally, or alternatively, the aspects may be performed by the UE 502 autonomously, in addition to, and/or in lieu of, operations of the base station 504.

In the illustrated aspect, the UE 502 may be configured to receive a set of CCs 506 provided/transmitted by the base station 504. In aspects, the configuration for the set of CCs 506 may be received at the UE 502 via RRC signaling and may include a list or other data structure having corresponding indexes for subsets of one or more CCs of the set of CCs 506 for which the UE may act upon accordingly for various configurations. The UE 502 may receive multiple configurations 508 provided/ transmitted by the base station 504. In aspects, the multiple configurations 508 may be received at the UE 502 via RRC signaling from the base station 504 and may be for one or more CG configurations for UL data signaling and/or one or more SPS configurations (e.g., the multiple configurations 508) provided/transmitted by the base station 504 for DL data signaling. As an example, the UE may receive multiple CG configurations. As another example, the UE may receive multiple SPS configurations. As another example, the UE may receive a single CG configuration and one or more SPS configurations. As another example, the UE may receive a single SPS configuration and one or more CG configurations. As another example, the UE may receive multiple CG configurations and multiple SPS configurations. The UE 502 may be further configured to receive one or more parameters 510, for the multiple configurations 508, provided /transmitted by the base station 504. In aspects, the one or more parameters 510 may be received at the UE 502 via RRC signaling and may include, without limitation, per-carrier parameters (e.g., parameters for SPS / CG configurations on a given CC that may be the same or different) , cross-carrier parameters (e.g., parameters for SPS /CG configurations across different CCs that may be the same or different) , and/or the like. In one configuration, the one or more parameters 510 may be received with the multiple configurations 508.

In aspects, the UE 502 may be configured, at 512, to select one or more CCs to transmit a single control information message 516 based on the multiple configurations 508 (e.g., one or more CG configurations and/or one or more SPS configurations) and a corresponding index (e.g., of the set of CCs 506) . At 514, the UE 502 may be configured to activate or deactivate ones of the multiple configurations 508 (e.g., one or more CG configurations and/or one or more SPS configurations) for the one or more CCs. In some aspects, the UE 502 may also be configured to perform other handling operations including, but without limitation, skipping, time /frequency shifting, changing of beams, etc. , ones of the multiple configurations 508 at 514, in addition to or in lieu of, the described activation or deactivation.

The UE 502 may be configured to provide or transmit a single control information message 516 to the base station 504. In aspects, the single control information message 516 may include information associated with handling any of the multiple configurations 508, as noted above, and/or may be comprised in uplink control information (UCI) or a medium access control (MAC) control element (MAC-CE) . In some aspects, the single control information message 516 may be included in a first signaling occasion for a CG that is based on at least one CG configuration of the multiple configurations 508 in a second signaling occasion for a PUCCH. In some aspects, the single control information message 516 may indicate or request at least one of configuration information, an activation, a deactivation, a first signaling occasion to be skipped, a second signaling occasion to be added, a time shift, a frequency shift, or a beam change, as described. In some aspects, the multiple configurations 508 (e.g., one or more CG configurations and/or one or more SPS configurations) may be associated with a single CC, where the single CC may be a CC on which the single control information message 516 is to be transmitted or may be another CC that is different from the CC on which the single control information message 516 is to be transmitted. In some aspects, the multiple configurations 508 may be associated with at least one CC that may include a first CC on which the single control information message 516 is to be transmitted and at least one additional CC that is different from the first CC on which the single control information message 516 is to be transmitted.

In some aspects, the single control information message 516 for the multiple configurations 508 may be associated with a single data stream over the first CC and a second CC of the at least one additional CC. In some aspects, the single control information message 516 for the multiple configurations 508 may be associated with a first data stream over the first CC and a second data stream over a second CC of the at least one additional CC. In some aspects, the single control information message 516 for the multiple configurations 508 may be a dynamic indication that indicates an unused portion of the UL data signaling, and in such aspects, the UE 502 may be further configured to jointly code the single control information message 516 across the first CC with a first portion of the single control information message 516 and a second CC of the at least one additional CC with a second portion of the single control information message 516.

The UE 502 may also be configured to transmit and/or receive signaling 518 to and/or from the base station 504. In aspects, signaling 518 may include the UL data signaling and/or or receiving the DL data signaling based on the control information provided at 516. As an example, the UL or DL data may include XR traffic, such as described in connection with FIG. 4, or may include other types of traffic. In some configurations, the signaling 518 may be transmitted and/or received via a CC (s) based on a configured time delay from the single control information message 516. In aspects, the time delay may be associated with at least one of a number of CCs of the at least one CC or a respective frequency of the at least one CC.

FIG. 6 is a diagram 600 illustrating examples of joint UL configuration handling across CCs, in various aspects relating to the communication flow in FIG. 5. Diagram 600 shows CG occasions on multiple CCs for a configuration 610 and a configuration 650. As noted herein, and as referenced in diagram 600, a UE may transmit a single control information message (e.g., single control information message 516 in FIG. 5) as UCI or a MAC-CE, and the control information message may be included in a signaling occasion for a PUCCH or may be multiplexed with a CG occasion. Additionally, CG instances are illustrated with a CG periodicity (which may be non-integer for XR) and example jitter, while the SPS occasions are illustrated with a SPS periodicity.

Configuration 610 illustrates several examples of joint UL configuration handling across CCs (afirst CC: CC1, and a second CC: CC2) . For illustrative clarity, two examples of CC2 are shown for CG occasions and for SPS occasions. A first single control information message, shown by example as UCI in a PUCCH in CC1 may be provided/transmitted by a UE to activate a first CG occasion in CC1, a first CG occasion in CC2, and/or a first SPS occasion in CC2. In some aspects, these described occasions may be indicated via multiple configurations from a base station, as noted herein. In the context of XR traffic, by way of example, if the UE determines that each of these described occasions may be utilized, the first single control information message may activate them. In some aspects, as shown by way of example, a CG occasion or an SPS occasion may follow the a single control information message based on a time delay (Delay) that may allow adequate time for a base station to act on the single control information message.

The first CG occasion on CC1 may also have a second single control information message multiplexed or otherwise included therein by the UE. In the illustrated example, in contrast to the first single control information message, the second single control information message may skip (or deactivate) a second CG occasion on CC1 and the second CG occasion on CC2. For instance, the UE may determine that there will be no traffic (e.g., XR UL data) for the second CG occasion on CC1 and the second CG occasion on CC2, and thus provide the second single control information message via UCI in the first CG occasion on CC1. Similarly, the UE may include a third single control information message in a third CG occasion on CC2. The third single control information message in the third CG occasion on CC2 may skip a third CG instance on CC1.

Configuration 610 also shows an aspect in which the first single control information message in the PUCCH may be in CC1, in CC2, or in both CC1 and CC2.

Referring to configuration 650, a single control information message that is jointly coded in PUCCHs across multiple CCs is illustrated, by way of example. For instance, CC1 in configuration 650 includes a first PUCCH with a first portion of a first single control information message and a second PUCCH with a second portion of the first single control information message. The first single control information message in CC1 and CC2 (e.g., via UCI or MAC-CE) may activate a first CG occasion for a first CG (CG1) and may activate a first CG occasion for a second CG (CG2) in CC1, while a second single control information message in the first CG occasion of CG1 on CC1 (e.g., via UCI or MAC-CE) may skip the second CG occasion of CG1 on CC1. Thus, a single control information message for multiple CG occasions and/or SPS occasions may jointly coded across different CCs respectively with a first portion and a second portion of the single control information message. The UE may be configured to determine if joint coding across CCs is utilized for the single control information message based on reliability of CCs, frequencies of CCs, and/or the like. Additionally, in aspects, a single control information message for two different CGs or two different SPSs on a single CC may be utilized, as shown.

FIG. 7 is a diagram 700 illustrating examples of joint UL configuration handling across CCs, in various aspects. Diagram 700 shows a configuration 710 and a configuration 750. As noted herein, and as referenced in diagram 700, a single control information message (e.g., single control information message 516 in FIG. 5) may be provided via UCI or MAC-CE and may be included in a signaling occasion for a PUCCH or may be multiplexed with a CG occasion. Additionally, CG instances are illustrated with a CG periodicity (which may be non-integer for XR) and example jitter.

Configuration 710 illustrates a configuration that may be similar to configuration 650 in FIG. 6, but where a single control information message coded in a PUCCH of one CC, by way of example, for different CGs. For instance, CC1 in configuration 710 includes a PUCCH with a first single control information message. The first single control information message in CC1 (e.g., via UCI or MAC-CE) may activate a first CG occasion for a first CG (CG1) and may activate a first CG occasion for a second CG (CG2) in CC1. A second single control information message in the first CG occasion of CG1 on CC1 (e.g., via UCI or MAC-CE) may cancel the second CG occasion of CG1 on CC1, and/or cancel CG2 entirely. Thus, a single control information message for two different CGs or two different SPSs on a single CC may be utilized, as shown.

Configuration 750, in contrast, illustrates a configuration by which an activation, a deactivation, a first signaling occasion to be skipped, a second signaling occasion to be added, a time shift, a frequency shift, a beam change, and/or the like for a CG or SPS in one CC may be indicated or requested in a single control information message in a different CC. For instance, CC1 in configuration 750 includes a PUCCH with a first single control information message. The first single control information message in CC1 (e.g., via UCI or MAC-CE) may activate a first CG occasion for a first CG (CG1) in CC2, which is a different CC than CC1. A second single control information message in the first CG occasion of CG1 on CC2 (e.g., via UCI or MAC-CE) may cancel the second CG occasion of CG1 on CC2, while also activating a first CG occasion for a second CG (CG2) on CC1 (which, as but one example, may be due to a frequency of CC1 and/or CC2) . Thus, a single control information message on a CC may be utilized for handling CG /SPS occasions on a different CC, as shown.

While FIGs. 6 and 7 show activations, skips, and cancellations, by way of illustrative examples for brevity and clarity, it is contemplated herein that a signaling occasion (s) to be added, a time shift and/or a frequency shift for an occasion (s) , a beam change, and/or the like for CG and/or SPS occasions may be included in addition to, or in lieu of, the illustrated aspects.

FIG. 8 is a flowchart 800 of a method of wireless communication, in various aspects. The method may be performed by a UE (e.g., the UE 104, 412, 502; the apparatus 1204) . In some aspects, the method may include aspects described in connection with the communication flow in FIG. 5 and/or aspects described in FIGs. 6, 7. The method provides for UL-based joint handling of cross-CC SPS and CG occasions that enables a UE to inform a network node (e.g., a base station) for characteristics of certain traffic and reduces processing for coding /decoding and utilization of signaling resources (both of which reduce power consumption) through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions.

At 802, the UE receives multiple configurations for at least one of a CG configuration for UL data signaling or a SPS configuration for DL data signaling. As an example, the reception may be performed by the component 198. FIGs. 5, 6, 7 illustrate an example of the UE 502 performing such a reception for multiple configurations, from a network node (e.g., the base station 504) .

The UE 502 may be configured to receive a set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) provided /transmitted by the base station 504. In aspects, the set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) may be received at the UE 502 via RRC signaling and may include a list or other data structure having corresponding indexes for subsets of one or more CCs of the set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) for which the UE may act upon accordingly for various configurations of CG /SPS occasions. The UE 502 may also be configured to receive multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) provided /transmitted by the base station 504. In aspects, the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be received at the UE 502 via RRC signaling and may be for one or more CG configurations for UL data signaling and/or one or more SPS configurations for DL data signaling, e.g., to receive multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) , provided /transmitted by the base station 504. The UE 502 may be further configured to receive one or more parameters 510, for the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) , provided /transmitted by the base station 504. In aspects, the one or more parameters 510 may be received at the UE 502 via RRC signaling and may include, without limitation, per-carrier parameters (e.g., parameters for SPS /CG configurations on a given CC that may be the same or different) , cross-carrier parameters (e.g., parameters for SPS /CG configurations across different CCs that may be the same or different) , and/or the like. In one configuration, the one or more parameters 510 may be received with the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) .

At 804, the UE transmits a single control information message for the multiple configurations for the at least one of the CG configuration or the SPS configuration. As an example, the transmission may be performed by the component 198. FIGs. 5, 6, 7 illustrate an example of the UE 502 performing such a transmission for a single control information message for a network node (e.g., the base station 504) .

The UE 502 may be configured, at 512, to select one or more CCs (e.g., from the set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) ) to transmit a single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) based on the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) (e.g., one or more CG configurations and/or one or more SPS configurations) and a corresponding index (e.g. , from the set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) ) . At 514, the UE 502 may be configured to activate or deactivate (e.g., 610, 650 in FIG. 6; 710, 750 in FIG. 7) ones of the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) (e.g. , one or more CG configurations and/or one or more SPS configurations) for the one or more CCs. In some aspects, the UE 502 may also be configured to perform other handling operations (e.g., 750 in FIG. 7) including, but without limitation, skipping, time /frequency shifting, changing of beams, etc. , ones of the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) at 514, in addition to or in lieu of, the described activation or deactivation (e.g., 610, 650 in FIG. 6; 710, 750 in FIG. 7) . The UE 502 may be configured to provide or transmit a single control information message 516 (e.g., control information (e.g., UCI /MAC-CE) in FIGS. 6, 7) to the base station 504. In aspects, the single control information message 516 (e.g. , control information (UCI /MAC-CE) in FIGS. 6, 7) may include information associated with handling any of the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) , as noted above, and/or may be comprised in uplink control information (UCI) or a medium access control (MAC) control element (MAC-CE) . In some aspects, the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) may be included in a first signaling occasion for a CG that is based on at least one CG configuration of the multiple configurations 508 (e.g. , CG /SPS occasions in FIGS. 6, 7) in a second signaling occasion for a PUCCH. In some aspects, the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) may indicate or request at least one of configuration information (e.g., 610, 650 in FIG. 6; 710, 750 in FIG. 7) , an activation, a deactivation, a first signaling occasion to be skipped, a second signaling occasion to be added, a time shift, a frequency shift, or a beam change, as described. In some aspects, the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) (e.g., one or more CG configurations and/or one or more SPS configurations) may be associated with a single CC, where the single CC may be a CC on which the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) is to be transmitted or may be another CC that is different from the CC on which the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) is to be transmitted. In some aspects, the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be associated with at least one CC that may include a first CC on which the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) is to be transmitted and at least one additional CC that is different from the first CC on which the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) is to be transmitted. In some aspects, the single control information message 516 (control information (e.g., UCI /MAC-CE) in FIGS. 6, 7) for the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be associated with a single data stream over the first CC and a second CC of the at least one additional CC (e.g., 610 in FIG. 6) . In some aspects, the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) for the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be associated with a first data stream over the first CC and a second data stream over a second CC of the at least one additional CC (e.g., 650 in FIG. 6; 750 in FIG. 7) . In some aspects, the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) for the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be a dynamic indication that indicates an unused portion of the UL data signaling (e.g., skipped occasions in FIGs. 6, 7) . In aspects, the UE 502 may be further configured to jointly code (e.g., 650 in FIG. 6) the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) across the first CC with a first portion of the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) and a second CC of the at least one additional CC with a second portion of the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) .

FIG. 9 is a flowchart 900 of a method of wireless communication, in various aspects. The method may be performed by a UE (e.g., the UE 104, 412, 502; the apparatus 1204) . In some aspects, the method may include aspects described in connection with the communication flow in FIG. 5 and/or aspects described in FIGs. 6, 7. The method provides for UL-based joint handling of cross-CC SPS and CG occasions that enables a UE to inform a network node (e.g., a base station) for characteristics of certain traffic and reduces processing for coding /decoding and utilization of signaling resources (both of which reduce power consumption) through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions.

At 902, the UE receives, via RRC signaling, a set of one or more CCs, where each of the one or more CCs in the set is associated with an index for a respective combination of the at least one of the CG configuration or the SPS configuration. As an example, the reception may be performed by the component 198.

The UE 502 may also be configured to receive multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) provided /transmitted by the base station 504. In aspects, the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) may be received at the UE 502 via RRC signaling and may be for one or more CG configurations for UL data signaling and/or one or more SPS configurations for DL data signaling, e.g., to receive multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) , provided /transmitted by the base station 504.

At 906, the UE receives, via RRC signaling, at least one parameter respectively associated with the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC. As an example, the reception may be performed by the component 198. FIG. 5 illustrates an example of the UE 502 performing such a reception for a parameter (s) from a network node (e.g., the base station 504) .

The UE 502 may be further configured to receive one or more parameters 510, for the multiple configurations 508, provided /transmitted by the base station 504. In aspects, the one or more parameters 510 may be received at the UE 502 via RRC signaling and may include, without limitation, per-carrier parameters (e.g., parameters for SPS /CG configurations on a given CC that may be the same or different) , cross-carrier parameters (e.g., parameters for SPS /CG configurations across different CCs that may be the same or different) , and/or the like. In one configuration, the one or more parameters 510 may be received with the multiple configurations 508.

At 908, the UE selects at least one of the one or more CCs for transmitting the single control information message based on the at least one of the CG configuration or the SPS configuration and a corresponding index. As an example, the selection may be performed by the component 198. FIGs. 5-7 illustrate an example of the UE 502 performing such a selection for a one or more CCs having SPS /CG occasions configured by a network node (e.g., the base station 504) .

The UE may be configured, at 512, to select one or more CCs to transmit a single control information message 516 based on the multiple configurations 508 (e.g., one or more CG configurations and/or one or more SPS configurations) and a corresponding index (e.g., of the set of CCs 506 (e.g., CC1 and CC2 in FIGs. 6, 7) ) .

At 910, the UE activates or deactivates the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC. As an example, the activation or deactivation may be performed by the component 198. FIGs. 5-7 illustrate an example of the UE 502 performing such activation or deactivation for CG /SPS occasions configured by a network node (e.g., the base station 504) .

The UE may be configured, at 514, to activate or deactivate (e.g., 610, 650 in FIG. 6; 710, 750 in FIG. 7) ones of the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) (e.g., one or more CG configurations and/or one or more SPS configurations) for the one or more CCs. In some aspects, the UE 502 may also be configured to perform other handling operations (e.g., 750 in FIG. 7) including, but without limitation, skipping, time /frequency shifting, changing of beams, etc. , ones of the multiple configurations 508 (e.g., CG /SPS occasions in FIGS. 6, 7) at 514, in addition to or in lieu of, the described activation or deactivation (e.g., 610, 650 in FIG. 6;710, 750 in FIG. 7) .

At 912, the UE determines if the single control information message is to be jointly coded across more than one CC. As an example, the determination may be performed by the component 198. FIGs. 5-7 illustrate an example of the UE 502 performing such a determination for transmission of the single control information message for a network node (e.g., the base station 504) .

The UE may be configured to determine if joint coding across CCs is utilized for the single control information message based on reliability of CCs, frequencies of CCs, and/or the like. If joint coding is utilized, flowchart 900 continues to 914; if not, flowchart 900 continues to 916.

At 914, the UE jointly codes the single control information message across the first CC with a first portion of the single control information message and a second CC of the at least one additional CC with a second portion of the single control information message. As an example, the joint coding may be performed by the component 198. FIGs. 5-7 illustrate an example of the UE 502 performing such joint coding for transmission of the single control information message for a network node (e.g., the base station 504) .

In aspects, the UE 502 may be configured to jointly code (e.g., 650 in FIG. 6) the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) across the first CC with a first portion of the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) and a second CC of the at least one additional CC with a second portion of the single control information message 516 (e.g., control information (UCI /MAC-CE) in FIGS. 6, 7) .

At 916, the UE transmits a single control information message for the multiple configurations for the at least one of the CG configuration or the SPS configuration. As an example, the transmission may be performed by the component 198.

In the configuration, the network entity 1302 may include means for receiving a single control information message for the multiple configurations for the at least one of the CG configuration or the SPS configuration. In one configuration, the network entity 1302 may also include means for transmitting, via RRC signaling, at least one parameter respectively associated with the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC, where the at least one parameter is associated with an activation or a deactivation for the multiple configurations for the at least one of the CG configuration or the SPS configuration for the at least one CC.

As described supra, the network entity 1302 may include the TX processor 316, the RX processor 370, and the controller/processor 375. As such, in one configuration, the means may be the TX processor 316, the RX processor 370, and/or the controller/processor 375 configured to perform the functions recited by the means.

A normal dynamic grant (DG) may be used to handle XR traffic, but this may include an expense of additional signaling (e.g., physical downlink control channel (PDCCH) ) and additional power consumption (e.g., PDCCH decoding) . Semi-persistent scheduling (SPS) and configured grant (CG) operations may be utilized as candidates for periodic XR traffic, however, because the number and sizes of packet per XR burst or period may not be constant, and at some instances, the network may not know beforehand the XR traffic details, a SPS and/or CG occasion may either be smaller or larger in terms of resources than what is include for a given XR burst. As a result, a regular application of SPS and/or CG occasions for XR bursts may wastes resource (e.g., if more resources than XR data are allocated) , may cause delays (e.g., if fewer resources than XR data are allocated) , may lead to unnecessary base station beam direction reservation for UL data (e.g., if more resources than XR data are allocated) , etc. While wireless communication networks, such as 5G NR networks, may support dynamic indications of unused an CG physical uplink shared channel (PUSCH) occasion (s) based on uplink control information (UCI) from the UE and multiple CG PUSCH transmission occasions in a period of a single CG PUSCH configuration, as noted above, this may include an expense of additional signaling and power for encoding /decoding.

The described aspects for UL-based joint handling of cross-CC SPS and CGs enable a UE and a base station (e.g., the network, generally) to each be aware of UL and DL characteristics, QoS metrics, and application layer attributes. In some examples, a UE may receive multiple configurations for a CG configuration (s) for UL data signaling and/or a SPS configuration (s) for DL data signaling, and transmit a single control information message associated with the multiple configurations for the CG configuration (s) and/or the SPS configuration (s) .

In some examples, by providing a single control information message for UL-based joint handling of cross-CC SPS and CGs, the described techniques can be used to reduce, or more efficiently use, processing resources for coding /decoding as well as UL /DL data signaling resources through joint activations, cancelations, and other configurations across one or more CCs for different numbers of SPS and/or CG occasions. Additionally, when a UE provides a single control information message across one or more CCs for multiple SPS and/or CG occasions, the network (e.g., a base station) is efficiently made aware of traffic characteristics (e.g., periodicity, multiple flows, jitter, latency, reliability, etc. , in XR) , and the network is thus enabled to further configure signaling and traffic with the UE, as indicated, for the described power and signaling efficiencies. In one example, this may enhance C-DRX and PDCCH monitoring for power savings, as well as enhancing SPS /CG and dynamic scheduling /grants for traffic capacity. Further, with respect to reliability, aspects may increase the reliability of the indicator (s) in the single control information message by providing it on or over multiple CCs or jointly coding across CCs.

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. 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. ”

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.
