[0002] This application claims the benefit of U.S. non-provisional patent application No. 18 / 508,113, filed November 13, 2023, entitled "WIDEBAND UE POWER SAVING BYSWITCHING WIDEBAND DATA TO NARROWBAND DATA WITH WIDEBAND REFERENCE SIGNAL", the entire contents of which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure relates generally to communication systems, and more specifically to a method for energy management in wireless communication. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems 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.

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

[0028] In some aspects of wireless communication, networks or wireless devices may be able to use ultra-wide bandwidth for communication (e.g., a bandwidth of 400 MHz to 8 GHz in ultra-wideband operation mode). Channel estimation over ultra-wide bandwidth allows networks or wireless devices to scan a larger bandwidth to identify suitable or desired subbands for subsequent communication (e.g., subbands with the highest quality or received power). However, in some aspects, wireless devices may not support (or may determine not to use) ultra-wide bandwidth for one or more of the channel estimation or data transmission processes. For wireless devices that do not support (or are determined not to use) ultra-wide bandwidth operation, an FMCW reference signal can be used to allow channel estimation over ultra-wide bandwidth to be performed using an operating mode (or baseband processor) associated with a (narrower) bandwidth (e.g., 20 MHz–400 MHz or greater for higher frequency ranges such as 6 GHz or sub-THz).

[0029] For example, the power (or energy) consumption associated with ultra-wideband operation can be greater due to a larger analog-to-digital conversion (ADC) sampling rate, a larger Fast Fourier Transform (FFT) size, or other factors. Based on this increased power consumption, a wireless device may determine to use narrowband operation mode even when ultra-wideband operation mode is available. For example, a wireless device may determine to operate in narrowband mode based on one or more of the amount of energy stored in the device's battery and / or the energy consumption to acquisition ratio (ECHR).

[0030] Various aspects generally relate to power saving for wireless devices with broadband (or ultra-wideband) capabilities. Some aspects more specifically relate to switching between a normal (e.g., broadband) operating mode and a power-saving (e.g., broadband reference signal and narrowband data) operating mode for power saving associated with configured granted or semi-persistent scheduled transmissions, while maintaining a broadband FMCW-based RS to identify suitable or desired subbands. In some examples, the method may include: detecting a first trigger condition at the wireless device; and sending a first indication to the network device for switching from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth, wherein at least one of the following is true: the second data bandwidth is less than the first data bandwidth and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth and the second data bandwidth is less than the second reference signal bandwidth; or the first data bandwidth is less than the second data bandwidth and the first reference signal bandwidth is greater than the first data bandwidth.

[0031] Specific aspects of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques can be used to manage power consumption at broadband-capable wireless devices by enabling switching between a broadband mode and a narrowband mode for data transmission while maintaining a broadband mode for RS operation.

[0032] The detailed descriptions following, illustrated with reference to the accompanying drawings, describe various configurations and do not represent the only configurations in which the concepts described herein can be practiced. To provide a thorough understanding of the various concepts, the detailed descriptions include specific details. However, these concepts can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0033] Various apparatuses and methods are presented with reference to several aspects of a telecommunications system. These apparatuses and methods are described in detail below and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0034] As an example, an element, any part of an element, or any combination of elements may be implemented as a "processing system" including one or more processors. When multiple processors are implemented, the multiple processors may perform functions individually or in combination. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, system-on-a-chip (SoCs), baseband processors, field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionalities described throughout this disclosure. One or more processors in the processing system can execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other terms, software should be broadly interpreted as instructions, instruction sets, code, code segments, program code, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, or any combination thereof.

[0035] Therefore, in one or more example aspects, specific implementations, and / or use cases, the described functionality may be implemented in hardware, software, or any combination thereof. If implemented in software, the functionality may be stored or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium accessible to a computer. By way of example, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disc storage devices, magnetic disk storage devices, other magnetic storage devices, combinations of these 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 accessible to a computer.

[0036] While aspects, implementations, and / or use cases are described herein by way of example, additional or different aspects, implementations, and / or use cases may arise in many different arrangements and scenarios. The aspects, implementations, and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, aspects, implementations, and / or use cases may arise via integrated chip implementations and other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specific to a use case or application, the described examples may exhibit broad applicability. Aspects, implementations, and / or use cases can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more of the technologies described herein. In some practical settings, devices incorporating the described aspects and features may also include additional components and features for implementing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily involve multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The techniques described herein can be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or decomposed components, end-user equipment, etc., of various sizes, shapes, and configurations.

[0037] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, radio access network (RAN) nodes, core network nodes, network elements or network equipment (such as base stations (BS)) or one or more units (or components) performing base station functions can be implemented in aggregated or decomposed architectures. For example, BSs (such as Node B (NB), evolved NB (eNB), NR BS, 5G NB, access point (AP), transmit / receive point (TRP), or cell, etc.) can be implemented as aggregated base stations (also known as standalone BS or monolithic BS) or decomposed base stations.

[0038] Aggregated base stations can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. Decentralized base stations can be configured to utilize a protocol stack that is physically or logically distributed across 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 respects, the CU may be implemented within a RAN node, and one or more DUs may co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may be implemented as a virtual unit, namely a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0039] Base station operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in Integrated Access Backhaul (IAB) networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)). Decomposition can include distributing functionality across two or more units in various physical locations, as well as virtually distributing the functionality of at least one unit, which enables flexibility in network design. The various units of a decomposed base station or decomposed RAN architecture can be configured to communicate wirelessly with at least one other unit.

[0040] Figure 1 Figure 100 illustrates an example of a wireless communication system and access network. The illustrated wireless communication system includes a decomposed base station architecture. The decomposed base station architecture may include one or more CUs 110, which may communicate directly with the core network 120 via a backhaul link, or indirectly with the core network 120 via one or more decomposed 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. CUs 110 may communicate with one or more DUs 130 via a corresponding midhaul link (such as an F1 interface). DUs 130 may communicate with one or more RUs 140 via a corresponding fronthaul link. RUs 140 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0041] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO frame 105) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of these units, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally, these units may include wireless interfaces that may include receivers, transmitters, or transceivers (such as RF transceivers) configured to receive signals via wireless transmission media and / or transmit signals to one or more other units.

[0042] In some aspects, the CU 110 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 110. The CU 110 can be configured to handle user plane functionality (i.e., Central Unit-User Plane (CU-UP)), control plane functionality (i.e., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 110 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 110 can be implemented to communicate with the DU 130 for network control and signaling, as needed.

[0043] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 140s. In some aspects, DU 130 may at least partially host one or more of the Radio Link Control (RLC) layer, Media 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, etc.) according to functional splits (such as those defined by 3GPP). In some aspects, DU 130 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0044] Lower-layer functionality can be implemented by one or more RU 140s. In some deployments, an RU140 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 both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 140 may be controlled by the corresponding DU 130. In some scenarios, this configuration enables the implementation of the DU 130 and CU 110 in cloud-based RAN architectures such as vRAN architectures.

[0045] SMO framework 105 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 105 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 105 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 190 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 110, DU 130, RU 140, and near-RT RIC 125. In some implementations, SMO framework 105 can communicate with the hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 111) via the O1 interface. Additionally, in some implementations, SMO framework 105 can communicate directly with one or more RU 140s via the O1 interface. SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of SMO framework 105.

[0046] The non-RT RIC 115 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence (AI) / machine learning (ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 125. The non-RT RIC 115 can be coupled to or communicate with the near-RT RIC 125, such as via an A1 interface. The near-RT RIC 125 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and action, connecting one or more CU 110s, one or more DU 130s, or both, and O-eNBs to the near-RT RIC 125.

[0047] 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 an external server. This information can be utilized by the near-RT RIC 125 and may be received from non-network data sources or network functions at the SMO framework 105 or the non-RT RIC 115. 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 in performance and use AI / ML models to perform corrective actions via the SMO framework 105 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0048] At least one of CU 110, DU 130, and RU 140 may be referred to as base station 102. Therefore, base station 102 may include one or more of CU 110, DU 130, and RU 140 (each component is indicated by a dashed line to indicate that each component may or may not be included in base station 102). Base station 102 provides UE 104 with an access point to core network 120. Base station 102 may include macro cells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Small cells include femtocells, picocells, and microcells. A network that includes both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include an evolved home node B (eNB) (HeNB), which can provide service to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU140 and UE 104 may include uplink (UL) transmission (also known as reverse link) from UE 104 to RU 140 and / or downlink (DL) transmission (also known as forward link) transmission from RU 140 to UE 104. The communication link may utilize multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may use one or more carriers. For each direction, the total number of carriers used for transmission can be up to [number missing]. Yx MHz ( x For each carrier allocated in carrier aggregation (of component carriers), base station 102 / UE 104 can use up to [number] carriers. Y A spectrum with a bandwidth of MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.). Carriers may or may not be adjacent to each other. Carrier allocation can be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). Component carriers may include primary component carriers and one or more secondary component carriers. The primary component carrier may be referred to as the primary cell (PCell) and the secondary component carrier may be referred to as the secondary cell (SCell).

[0049] Some UEs 104 can communicate with each other using device-to-device (D2D) communication link 158. D2D communication link 158 can use DL / UL wireless wide area network (WWAN) spectrum. D2D communication link 158 can use one or more sidelink channels, such as Physical Sidelink Broadcast Channel (PSBCH), Physical Sidelink Discovery Channel (PSDCH), Physical Sidelink Shared Channel (PSSCH), and Physical Sidelink Control Channel (PSCCH). D2D communication can be performed through various wireless D2D communication systems, such as Bluetooth. ™ (Bluetooth is a trademark of the Bluetooth Special Interest Group (SIG), and is based on the IEEE 802.11 standard for Wi-Fi.) ™(Wi-Fi is a trademark of the Wi-Fi Alliance), LTE, or NR.

[0050] The wireless communication system may also include a Wi-Fi AP 150, which communicates with the UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in an unlicensed spectrum such as 5 GHz. When communicating in unlicensed spectrum, the UE 104 / AP 150 may perform a free channel assessment (CCA) to determine whether the channel is available before communication.

[0051] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc., based on frequency / wavelength. In 5G NR, two initial operating bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). Although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the "sub-6GHz" band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although this is distinct from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU).

[0052] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have designated the operating bands for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been designated as the frequency range designations FR2-2 (52.6 GHz to 71 GHz), FR4 (71 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher bands falls within the EHF band.

[0053] In view of the above, unless otherwise specifically stated, the term "below 6 GHz" as used herein can broadly refer to frequencies less than 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, the term "millimeter wave" as used herein can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR2-2 and / or FR5, or within the EHF band.

[0054] Base station 102 and UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. Base station 102 may transmit beamformed signals 182 to UE 104 in one or more transmit directions. UE 104 may receive beamformed signals from base station 102 in one or more receive directions. UE 104 may also transmit beamformed signals 184 to base station 102 in one or more transmit directions. Base station 102 may receive beamformed signals from UE 104 in one or more receive directions. Base station 102 / UE 104 may perform beamforming training to determine the optimal receive and transmit directions for each of base station 102 / UE 104. The transmit and receive directions of base station 102 may or may not be the same. The transmit and receive directions of UE 104 may or may not be the same.

[0055] Base station 102 may include and / or be referred to as gNB, Node B, eNB, access point, transceiver base station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), TRP, network node, network entity, network equipment, or some other suitable terminology. Base station 102 may be implemented as an integrated access and backhaul (IAB) node, relay node, sidelink node, aggregated (monolithic) base station with baseband units (BBU) (including CU and DU) and RU, or may be implemented as a decomposed base station including one or more of CU, DU, and / or RU. A collection of base stations that may include decomposed base stations and / or aggregated base stations may be referred to as Next Generation (NG) RAN (NG-RAN).

[0056] The core network 120 may include Access and Mobility Management Function (AMF) 161, Session Management Function (SMF) 162, User Plane Function (UPF) 163, Unified Data Management (UDM) 164, one or more location servers 168, and other functional entities. AMF 161 is the control node that handles signaling between UE 104 and the core network 120. AMF 161 supports registration management, connection management, mobility management, and other functions. SMF 162 supports session management and other functions. UPF 163 supports packet routing, packet forwarding, and other functions. UDM 164 supports authentication and key agreement (AKA) credential generation, user identity processing, access authorization, and subscription management. One or more location servers 168 are exemplified as including a Gateway Mobile Location Center (GMLC) 165 and a Location Management Function (LMF) 166. However, generally, one or more location servers 168 may include one or more location / positioning servers, which may include one or more of GMLC 165, LMF 166, Position Determination Entity (PDE), Serving Mobile Location Center (SMLC), Mobile Location Center (MPC), etc. GMLC 165 and LMF 166 support UE location services. GMLC 165 provides an interface for clients / applications (e.g., emergency services) to access UE location information. LMF 166 receives measurement and auxiliary information from NG-RAN and UE 104 via AMF 161 to calculate the location of UE 104. NG-RAN may use one or more positioning methods to determine the location of UE 104. Positioning UE 104 may involve signal measurement, location estimation, and optional speed calculation based on these measurements. Signal measurement may be performed by UE 104 and / or base station 102 serving UE 104. The measured signals may be based on one or more of the following systems / signals / sensors: Satellite Positioning System (SaPS) 170 (e.g., Global Navigation Satellite System (GNSS), Global Positioning System (GPS), Non-Terrestrial Network (NTN) or other position / location systems), LTE signals, Wireless Local Area Network (WLAN) signals, Bluetooth signals, Terrestrial Beacon System (TBS), sensor-based information (e.g., barometric pressure sensor, motion sensor), NR Enhanced Cell ID (NR E-CID) method, NR signals (e.g., multiple round-trip time (multiple RTT), DL departure angle (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.

[0057] Examples of UE 104 include cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, GPS devices, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet devices, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional device. Some UEs in UE 104 may be referred to as IoT devices (e.g., parking meters, air pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, mobile phone, user agent, mobile client, client, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and / or individually.

[0058] Refer again Figure 1In some respects, UE 104 may have a wideband to narrowband (WB to NB) mode adjustment component 198, which may be configured to: detect a first trigger condition at a radio device; and send a first indication to a network device for switching from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth, wherein at least one of the following is true: the second data bandwidth is less than the first data bandwidth and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth and the second data bandwidth is less than the second reference signal bandwidth; or the first data bandwidth is less than the second data bandwidth and the first reference signal bandwidth is greater than the first data bandwidth. In some aspects, base station 102 may have a WB-to-NB mode adjustment component 199, which may be configured to receive from a wireless device a first indication for switching from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth, wherein at least one of the following is true: the second data bandwidth is less than the first data bandwidth and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth and the second data bandwidth is less than the second reference signal bandwidth; or the first data bandwidth is less than the second data bandwidth and the first reference signal bandwidth is greater than the first data bandwidth. The WB-to-NB mode adjustment component 199 may be further configured to transmit data signals via the second data bandwidth and reference signals via the second reference signal bandwidth for the wireless device. While the following description may focus on 5G NR, the concepts described herein may be applicable to other similar fields, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0059] Figure 2A Figure 200 illustrates an example of the first subframe within a 5G NR frame structure. Figure 2B Figure 230 illustrates an example of a DL channel within a 5G NR subframe. Figure 2C Figure 250 is an example of a second subframe within a 5G NR frame structure. Figure 2D Figure 280 illustrates an example of a UL channel within a 5G NR subframe. The 5G NR frame structure can be Frequency Division Duplex (FDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to either DL or UL), or Time Division Duplex (TDD) (where subframes within a specific set of subcarriers (carrier system bandwidth) are dedicated to both DL and UL). Figure 2A , Figure 2CIn the provided example, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured using slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible and can be used between DL / UL, and subframe 3 is configured using slot format 1 (all of which are UL). Although subframes 3 and 4 are shown as having slot formats 1 and 28 respectively, any particular subframe can be configured using any of the various available slot formats 0-61. Slot formats 0 and 1 are both DL and UL, respectively. Other slot formats 2-61 include a mixture of DL, UL, and flexible symbols. The UE is configured using the slot format via the received Slot Format Indicator (SFI) (dynamically configured via DL Control Information (DCI) or semi-statically / statically configured via Radio Resource Control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0060] Figures 2A to 2D The frame structure is illustrated, and aspects of this disclosure are applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10 ms) can be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include micro-time slots, which may include 7, 4, or 2 symbols. Each time slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each time slot may include 14 symbols, and for extended CP, each time slot may include 12 symbols. Symbols on the DL may be CP Orthogonal Frequency Division Multiplexing (OFDM) (CP-OFDM) symbols. Symbols on the UL may be CP-OFDM symbols (for high-throughput scenarios) or Discrete Fourier Transform (DFT) Extended OFDM (DFT-s-OFDM) symbols (for power-constrained scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and a parameter set. The parameter set defines the subcarrier spacing (SCS) (see Table 1). Symbol length / duration can be scaled by 1 / SCS.

[0061]

[0062] Table 1: Parameter Set, SCS, and CP

[0063] For a normal CP (14 symbols / slot), different parameter sets µ 0 through 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For an extended CP, parameter set 2 allows 4 slots per subframe. Therefore, for a normal CP and parameter set µ, there are 14 symbols / slot and 2... µ One time slot / subframe. Subcarrier spacing can be equal to ,in The parameter sets are 0 to 4. Therefore, the subcarrier spacing is 15 kHz for parameter set µ=0 and 240 kHz for parameter set µ=4. The symbol length / duration is negatively correlated with the subcarrier spacing. Figures 2A to 2D Examples of a normal frequency division multiplexing (CP) with 14 symbols per time slot and a parameter set of µ=2 with 4 time slots per subframe are provided. The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within the frame set, there may be one or more distinct bandwidth portions (BWPs) of frequency division multiplexing (see [link to relevant documentation]). Figure 2B Each BWP can have a specific set of parameters and CP (normal or extended).

[0064] A resource grid can be used to represent the frame structure. Each time slot consists of a resource block (RB) extending for 12 consecutive subcarriers (also known as a physical RB (PRB)). The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0065] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. RS may include demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS).

[0066] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE comprising six RE Groups (REGs), each REG comprising 12 consecutive REs in the OFDM symbol of the RB. A PDCCH within a BWP can be referred to as a Control Resource Set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., a common search space, a UE-specific search space) during PDCCH monitoring timing on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The Primary Synchronization Signal (PSS) may be located within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identification. The Secondary Synchronization Signal (SSS) may be located within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the Physical Layer Cell Identifier Group Number and radio frame timing. Based on the Physical Layer Identifier and the Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block (also known as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted via the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0067] like Figure 2C As illustrated, some REs in 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 can transmit DM-RS for the Physical Uplink Control Channel (PUCCH) and DM-RS for the Physical Uplink Shared Channel (PUSCH). The PUSCH DM-RS can be transmitted in the first or first two symbols of the PUSCH. Depending on whether a short or long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS can be transmitted in different configurations. The UE can transmit a Sounding Reference Signal (SRS). The SRS can be transmitted in the last symbol of a subframe. The SRS can have a comb structure, and the UE can transmit the SRS on one of the comb teeth. The SRS can be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0068] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUCCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCIs.

[0069] Figure 3 This is a block diagram illustrating communication between base station 310 and UE 350 in the access network. In the DL, Internet Protocol (IP) packets can be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functionality. Layer 3 includes the Radio Resource Control (RRC) layer, and Layer 2 includes the Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, and Media Access Control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the delivery of upper-layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer 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 via HARQ, priority handling, and logical channel priority ordering.

[0070] Transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) decoding / decoding of the transport channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. TX processor 316 processes the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The decoded and modulated symbols can then be divided into parallel streams. Each stream can then be mapped to OFDM subcarriers, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently combined using inverse fast Fourier transform (IFFT) to produce a physical channel carrying a stream of time-domain OFDM symbols. The OFDM stream undergoes spatial pre-decoding to generate multiple spatial streams. A channel estimate from channel estimator 374 can be used to determine the decoding and modulation scheme, as well as for spatial processing. This channel estimate can be derived from a reference signal transmitted by UE 350 and / or channel condition feedback. Each spatial stream can then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx can use the corresponding spatial stream to modulate a radio frequency (RF) carrier for transmission.

[0071] At UE 350, each receiver 354Rx receives signals via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides that information to the receive (RX) processor 356. The TX processor 368 and RX processor 356 implement Layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for UE 350. If multiple spatial streams are destined for UE 350, the RX processor 356 can combine them into a single OFDM symbol stream. The RX processor 356 then uses a Fast Fourier Transform (FFT) to transform the OFDM symbol stream from the time domain to the frequency domain. The frequency domain signal consists of a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, along with the reference signal, are recovered and demodulated by determining the most probable signal constellation points transmitted by base station 310. These soft decisions can be based on a channel estimate calculated by channel estimator 358. Subsequently, the soft decision is decoded and deinterleaved to recover the data and control signals originally transmitted by base station 310 on the physical channel. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functionality.

[0072] The controller / processor 359 may be associated with at least one memory 360 storing program code and data. The at least one memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing between transport and logical channels to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0073] Similar to the functionality described in conjunction with DL transmission performed by base station 310, controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connectivity, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with upper-layer PDU delivery, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer 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 via HARQ, priority handling, and logical channel priority ordering.

[0074] The TX processor 368 can use the channel estimate derived from the reference signal or feedback transmitted by the channel estimator 358 from the base station 310 to select an appropriate decoding and modulation scheme and facilitate spatial processing. The spatial stream generated by the TX processor 368 can be provided to different antennas 352 via individual transmitters 354Tx. Each transmitter 354Tx can use the corresponding spatial stream to modulate an RF carrier for transmission.

[0075] UL transmission is processed at base station 310 in a manner similar to that described in conjunction with the receiver function at UE 350. Each receiver 318Rx receives signals via its corresponding antenna 320. Each receiver 318Rx recovers the information modulated onto the RF carrier and provides that information to RX processor 370.

[0076] The controller / processor 375 may be associated with at least one memory 376 storing program code and data. The at least one memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets between transport and logical channels. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0077] At least one of the TX processor 368, RX processor 356, and controller / processor 359 can be configured to perform coupling. Figure 1 The WB to NB mode adjustment components 199 198 in various aspects.

[0078] At least one of the TX processor 316, RX processor 370, and controller / processor 375 can be configured to perform coupling. Figure 1 The WB to NB mode adjustment component 199 199 in all aspects.

[0079] In some aspects of wireless communication, networks or wireless devices may be able to use ultra-wide bandwidth for communication (e.g., a bandwidth of 400 MHz to 8 GHz in ultra-wideband operation mode). Channel estimation over ultra-wide bandwidth allows networks or wireless devices to scan a larger bandwidth to identify suitable or desired subbands for subsequent communication (e.g., subbands with the highest quality or received power). However, in some aspects, wireless devices may not support (or may determine not to use) ultra-wide bandwidth for one or more of the channel estimation or data transmission processes. For wireless devices that do not support (or are determined not to use) ultra-wide bandwidth operation, an FMCW reference signal can be used to allow channel estimation over ultra-wide bandwidth to be performed using an operating mode (or baseband processor) associated with a (narrower) bandwidth (e.g., 20 MHz–400 MHz or greater for higher frequency ranges such as 6 GHz or sub-THz).

[0080] For example, the power (or energy) consumption associated with ultra-wideband operating mode may be greater due to a larger ADC sampling rate, a larger FFT size, or other factors. Based on the increased power consumption, a wireless device may determine to use narrowband operating mode even when ultra-wideband operating mode is available. For example, a wireless device may determine to operate in narrowband operating mode based on one or more of the amount of energy stored in the wireless device's battery and / or ECHR (the ratio between the energy consumption associated with the wireless device's planned or possible operation and the energy received or recovered at the wireless device based on energy harvesting operations, such as solar energy, thermal energy, or RF radiation).

[0081] Various aspects generally relate to power saving for wireless devices with broadband (or ultra-wideband) capabilities. Some aspects more specifically relate to switching between a broadband operating mode and a narrowband operating mode for power saving associated with configured granted or semi-persistent scheduled transmissions, while maintaining a broadband FMCW-based RS to identify suitable or desired subbands. In some examples, the method may include: detecting a first triggering condition (e.g., a triggering condition related to energy available at the wireless device); and sending a first indication to the network device for switching from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth, wherein at least one of the following is true: the second data bandwidth is less than the first data bandwidth and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth and the second data bandwidth is less than the second reference signal bandwidth; or the first data bandwidth is less than the second data bandwidth and the first reference signal bandwidth is greater than the first data bandwidth.

[0082] Figure 4 Figure 400 illustrates the use of FMCW RS on a wideband (or ultra-wideband) BWP 410 to determine an optimized or suitable set of REs for relevant data transmission, or on a narrowband BWP 420. In some aspects, FMCW RS can be used to estimate the channel. For example, FMCW RS can be used to generate information about the amplitude of the signal as a function of the REs in the WB BWP 410, as shown in Figure 430. This information can be used to determine one or more suitable or desired bandwidths (e.g., suitable or desired bandwidth 433) associated with large amplitude or high channel quality (e.g., as measured by Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Noise Ratio (SNR)) and / or unsuitable or undesirable bandwidths (e.g., unsuitable or undesirable bandwidth 435) associated with small amplitude or low channel quality. In some aspects, the use of FMCW allows wireless devices to use processing resources (e.g., narrowband baseband processors) associated with NB CG or SPS data transmission to process the WB RS.

[0083] Figure 5Figure 500 illustrates elements associated with a digital transmit architecture 510, a digital receive architecture 520, an analog transmit architecture 530, and an analog receive architecture 540 according to some aspects of this disclosure. Transmission of FMCW RS may be via digital transmission associated with either the digital transmit architecture 510 or the analog transmit architecture 530. In some aspects, when operating in WB operating mode (using a WB BWP for RS and / or data transmission), the wireless device may receive (and process) FMCW RS via the digital receive architecture 520. In some aspects, the wireless device may receive (and process) FMCW RS via the analog receive architecture 540. In some aspects, using the analog receive architecture 540 to receive and process FMCW RS reduces the resources and / or power associated with reception and processing (e.g., associated with a sampling rate that can be reduced to approximately 1 / 16) compared to using the digital receive architecture 520.

[0084] Figure 6 This is a set of diagrams, including diagram 600 (which illustrates a receiving architecture associated with a wireless device capable of switching between a normal (or WB RS and WBDL data) operating mode and a power-saving (WB RS and NB DL data) operating mode), and diagram 650 (which illustrates a time interval associated with switching between different operating modes), according to some aspects of this disclosure. In some aspects, in a normal operating mode (e.g., an operating mode in which the same BWP is used for transmissions associated with RS, DL data, and UL data), the wireless device can use a normal mode receiving architecture 610. In some aspects, when operating in a power-saving mode associated with using a WB BWP for transmissions associated with (FMCW) RS, while using an NB BWP for transmissions associated with at least DL data, the wireless device can switch to using a power-saving mode receiving architecture 620 (where UL data can be transmitted using either a WB BWP or an NB BWP even in the power-saving operating mode). In some aspects, the power-saving mode receiver architecture 620 may include a first sub-architecture (or processing pipeline) associated with processing data 630 and a second sub-architecture (or processing pipeline) associated with processing RS 640. For example, by using a local FMCW mixer 641 as input to a low-pass filter (LPF) 623 and providing the output to a low-rate ADC 625, the wireless device can reduce the processing power associated with channel estimation on WB BWP (e.g., reduce it to a level similar to the processing power associated with processing data 630 based on using the same components at the same sampling rate).

[0085] Figure 650 illustrates a set of time slots associated with switching between different modes or data types within a mode. For example, a transition from WB or normal operating mode 660 to power-saving operating mode 670 (or from power-saving operating mode 670 to WB or normal operating mode 680) may be associated with a minimum time slot T1 (or T2), respectively. When operating in power-saving operating mode 670, a transition from receiving WB FMCW RS 671 to receiving NB data 673 (or from NB data 673 to WBFMCW RS 675) may be associated with a minimum time slot T4 (or T3), respectively.

[0086] Figure 7 Figure 700 illustrates different configurations of RS and data transmission associated with SPS or CG timing, according to some aspects of this disclosure. In some aspects, a WB or normal operation mode may be associated with a first SPS and / or CG timing configuration 710, which is associated with a first reference signal bandwidth (e.g., the WB RS bandwidth or BWP associated with the FMCW RS) and a first data bandwidth (e.g., the WB data bandwidth or BWP associated with data transmission, which is the same as or has a similar size to the BWP associated with the WB RS). A power-saving mode may be associated with one of a second SPS and / or CG timing configuration 720, a third SPS and / or CG timing configuration 730, and / or a fourth SPS and / or CG timing configuration 740. The bandwidth or BWP associated with the RS (e.g., FMCW RS) during one of the SPS and / or CG timings in configurations 720-740 using SPS and / or CG may be the same as the bandwidth or BWP associated with the RS during the SPS and / or CG timings in configuration 710 using SPS and / or CG. However, the bandwidth or BWP associated with data transmission during one of the SPS and / or CG timings in configurations 720-740 using SPS and / or CG may be less than the bandwidth or BWP associated with the RS during the SPS and / or CG timings in configuration 710 using SPS and / or CG. In some aspects, the FMCW RS using WB BWP may be a single-symbol FMCW 750 or a multi-symbol FMCW RS 760. In some aspects, the CP for the multi-symbol FMCW RS 760 may involve frequency hopping.

[0087] Figure 8Figure 800 illustrates energy consumption and energy harvesting that can be associated with normal operating mode and power-saving operating mode according to some aspects of this disclosure. For example, for a first transmission associated with a first total power consumption, first graph 810 illustrates that in the first normal operating mode, the energy consumption rate may exceed the energy harvesting rate during a first time period, which may cause the wireless device to run out of power (or not have enough power) to complete the first transmission. Second graph 820 illustrates that in a power-saving operating mode (associated with a lower energy consumption rate), for the same total energy consumption (or total power consumption), the energy harvesting rate may exceed the energy consumption rate, making it less likely that the wireless device will run out of power (or not have enough power).

[0088] In some aspects, the expected energy consumption rate to energy harvesting rate (ECHR) ratio in a first, normal, or WB operating mode can be used to trigger a transition to a second, power-saving, or NB operating mode. In some aspects, one or more ECHR thresholds can be associated with one or more stored energy thresholds. For example, if the stored energy at the wireless device (e.g., associated with battery power) is below a first threshold (e.g., 10% or 20%), the ECHR threshold used to trigger a power-saving mode can be 1 (e.g., an expected ECHR value greater than 1 triggers a transition to power-saving mode), while for stored energy above the first threshold (and below the next threshold), the ECHR threshold can be set to a second value (an expected ECHR value greater than 1.25 triggers a transition to power-saving mode). In some aspects, the ECHR threshold can be a function of stored energy, energy harvesting rate, and the expected time for the wireless to operate (or the expected time before the wireless runs out of energy), rather than a predetermined threshold. For example, to utilize sufficient stored energy for 30 minutes of operation for 1 hour, the ECHR should not be greater than 2 (and can be determined based on an error margin or safety factor to account for deviations from expected energy consumption and / or energy harvesting). For indeterminate operations, ECHR can be set to no greater than 1 (or less than 1 to allow for error margin). In some respects, the stored energy (e.g., battery life) threshold can be associated with triggering a transition to power-saving mode, regardless of ECHR or other energy consumption or energy harvesting characteristics.

[0089] Figure 9 This is a call flow diagram 900 illustrating a method for power saving at a UE 904 (e.g., a wireless device) communicating with a base station 902 (e.g., as an example, a network device or network node that may include one or more components of a decomposed base station) according to some aspects of this disclosure. In some aspects, the functionality attributable to base station 902 may be provided by a network entity, network node, or network device (as described above regarding...). Figure 1The functions described herein are performed by one or more components of a single network entity / node / device or a decomposed network entity / node / device. Similarly, in some aspects, the functions attributable to UE 904 may be performed by one or more components of a wireless device that supports communication with the network entity / node / device. Therefore, the reference to “transmit” in the following description may be understood to mean that the first component of base station 902 (or UE 904) outputs (or provides) an indication of the content to be transmitted by different components of base station 902 (or UE 904). Similarly, the reference to “receive” in the following description may be understood to mean that the first component of base station 902 (or UE 904) receives the transmitted signal and outputs (or provides) the received signal (or information based on the received signal) to different components of base station 902 (or UE 904).

[0090] In some aspects, base station 902 may exchange a set of WB SPS / CG configuration messages 906 with UE 904. In some aspects, the set of WB SPS / CG configuration messages 906 may be associated with communication between base station 902 and UE 904. In some aspects, as part of configuration communication, UE 904 may send an indication of the ability to use a power-saving operating mode associated with WB FMCW RS and NB data transmission. In some aspects, the indication of capability may include instructions for use such as regarding... Figure 6 The minimum set of time intervals between the described operating modes and / or transmission types (e.g., Figure 6 Instructions for T1, T2, T3, and / or T4. (As per...) Figure 7 As described, in some aspects, the WB SPS / CG configuration message 906 may include RS BWP and data BWP having similar or equal size and / or location in the frequency domain. Based on the WB SPS / CG configuration message 906, UE 904 and base station 902 may exchange normal mode communication 908 including WB RS (e.g., FMCW RS or non-FMCW RS) and one or more WB data transmissions (DL transmission and / or UL transmission).

[0091] At position 910, UE 904 can detect triggered events. (See also: Regarding...) Figure 8 As explained, the triggering event may be based on one or more thresholds associated with ECHR and / or stored energy. For example, at 910, UE 904 may detect an ECHR higher than 1 and / or stored energy lower than a first threshold (e.g., associated with a duration of 30 minutes or some other configuration of operation). Based on the detection of the triggering event at 910, the UE may determine to instruct base station 902 to begin transmission using a power-saving operating mode.

[0092] Based on the detection of a trigger event at 910, UE 904 may send a transition indication and / or request 912, and base station 902 may receive the transition indication and / or request, which instructs base station 902 to send an updated SPS and / or CG timing configuration and / or indication associated with a power-saving operating mode and / or transition to a power-saving operating mode. In some aspects, the transition indication and / or request 912 may include an indication of a suitable or desired NB BWP (e.g., an indication of one or more RE sets within a WB BWP associated with a normal operating mode, the one or more RE sets having channel quality that satisfies a threshold quality value such as that measured by RSRP, RSRQ, or SNR). Based on the transition indication and / or request 912, the base station may determine a configuration for one or more BWPs associated with the power-saving operating mode (e.g., at least one WB BWP for channel measurement and at least one BWP for NB data transmission). Based on the determined configuration for the one or more BWPs, base station 902 may send a BWP configuration indication 914, and UE 904 may receive the BWP configuration indication. In some aspects, the BWP configuration indication 914 may include indications of the duration of implementing the BWP configuration indication 914 and / or the time at which the BWP configuration indication 914 is implemented. In some aspects, the BWP configuration indication 914 may include indications of a wideband reference signal bandwidth and a narrowband data bandwidth. In some aspects, the BWP configuration indication 914 may include indications for activating the wideband reference signal bandwidth during a first time period and / or for activating the narrowband data bandwidth during at least a portion of the first time period. In some aspects, the narrowband data bandwidth may be used for DL ​​data transmission or for both DL data transmission and UL data transmission.

[0093] At point 916, base station 902 and UE 904 can switch to a power-saving operation mode. In association with the power-saving mode, base station 902 can transmit data such as... Figure 7 At least one WB FMCW RS transmission 918 and NB SPS / CG data transmission 920 associated with one or more SPS / CG timings (e.g., one of SPS and / or CG configurations 720-740), and UE 904 is capable of receiving these transmissions. In some aspects, at 921, UE 904 can use [the technology related to] [the specific technology]. Figure 6 The same baseband processor described uses the power-saving mode receiver architecture 620 to handle WB FMCW RS transmit 918 and NB SPS / CG data transmit 920.

[0094] In some aspects, at 922, UE 904 may monitor the WB channel based on WB FMCW RS transmission 918 and determine an appropriate or desired NB BWP for data transmission updates. Based on the appropriate or desired NB BWP for data transmission determined at 922, UE 904 may transmit an NB BWP selection indication 924, which base station 902 may receive. This NB BWP selection indication instructs base station 902 to transmit updated SPS and / or CG timing configurations and / or indications associated with power-saving operating modes. In some aspects, NB BWP selection indication 924 may include an indication of an updated appropriate or desired NB BWP (e.g., an indication of an update to one or more RE sets within a WB BWP associated with the WB FMCW RS, the one or more RE sets having channel quality that satisfies a threshold quality value such as that measured by RSRP, RSRQ, or SNR). For example, refer to... Figure 7 The NB BWP selection indication 924 may indicate a transition between any of the second SPS and / or CG timing configuration 720, the third SPS and / or CG timing configuration 730, and / or the fourth SPS and / or CG timing configuration 740. Based on the NB BWP selection indication 924, the base station may determine an updated configuration for one or more BWPs associated with a power-saving operating mode (e.g., at least one WB BWP for channel measurement and at least one BWP for NB data transmission). Based on the determined configuration for one or more BWPs, the base station 902 may transmit an NB BWP reconfiguration indication 926, and the UE 904 may receive the NB BWP reconfiguration indication. In some aspects, the NB BWP reconfiguration indication 926 may include an indication of the duration of implementing the NB BWP reconfiguration indication 926 and / or the time at which the NB BWP reconfiguration indication 926 is implemented. In some aspects, the NB BWP reconfiguration indication 926 may include an indication of an updated wideband reference signal bandwidth and an updated narrowband data bandwidth. In some aspects, the NB BWP reconfiguration instruction 926 may include an instruction for activating updated broadband reference signal bandwidth during a first time period and / or an instruction for activating updated narrowband data bandwidth during at least a portion of the first time period.

[0095] In association with power saving mode and NB BWP reconfiguration indication 926, base station 902 may send information such as regarding power saving mode and NB BWP reconfiguration indication 926. Figure 7 At least one WB FMCW RS transmission 928 and NB SPS / CG data transmission 930 associated with one or more SPS / CG timings (e.g., one of SPS and / or CG configurations 720-740), and UE 904 is capable of receiving these transmissions.

[0096] At position 932, UE 904 can detect additional triggering events. (See also: Regarding...) Figure 8 As explained, the triggering event may be based on one or more thresholds associated with ECHR and / or storage energy. For example, at 932, UE 904 may detect an ECHR below 1 and / or storage energy above a first threshold (e.g., associated with a duration of 30 minutes or some other configuration of operation). Based on the detection of the triggering event at 932, the UE may determine that the power-saving mode is no longer appropriate or desired and may instruct base station 902 to begin transmission using normal operating mode. Alternatively, additional triggering events may be associated with different thresholds of ECHR and / or storage energy, indicating a smaller BWP associated with the NB data BWP. Based on the additional triggering event detected at 932, UE 904 may send a transition indication and / or request 934, and base station 902 may receive the transition indication and / or request to transition to normal operating mode and / or a power-saving operating mode with a smaller (or larger) BWP for data transmission. For example, refer to Figure 7 The transition instruction and / or request 934 may indicate a transition between the current SPS and / or CG timing configuration (e.g., any one of SPS and / or CG timing configurations 720-740) and a different SPS and / or CG timing configuration (e.g., another one of SPS and / or CG configurations 710-740).

[0097] Based on the transition indication and / or request 934, base station 902 may send a BWP reconfiguration indication 936, and UE 904 may receive the BWP reconfiguration indication. The BWP reconfiguration indication 936 may include indications of the WB RS and WB data BWP associated with the normal operating mode, or a newer NB data BWP (and in some aspects, a newer WB FMCW RS BWP). In some aspects, the BWP reconfiguration indication 936 may include indications of the duration for implementing the BWP reconfiguration indication 936 and / or the time for implementing the BWP reconfiguration indication 936. In some aspects, the BWP reconfiguration indication 936 may include indications of an updated wideband reference signal bandwidth and an updated narrowband data bandwidth. In some aspects, the BWP reconfiguration indication 936 may include indications for activating the updated wideband reference signal bandwidth within a first time period and / or for activating the updated narrowband data bandwidth during at least a portion of the first time period. Based on the BWP reconfiguration indication 936, base station 902 and UE 904 may exchange communications 938.

[0098] Figure 10This is a flowchart 1000 of a wireless communication method. The method can be performed by a UE (e.g., UE 104; device 1404). In some aspects, the UE can transmit an indication of the ability of the same baseband processor to process at least one reference signal using a bandwidth larger than that of the associated data signal. For example, 1002 can be performed by... Figure 14 The application processor 1406, cellular baseband processor 1424, transceiver 1422, antenna 1480, and / or WB to NB mode adjustment component 198 are executed. In some aspects, at least one reference signal may be an FMCW reference signal. (Refer to...) Figure 9 For example, as part of configuring resources for communication, UE 904 may send an indication of the ability to use a power-saving operating mode associated with WB FMCW RS and NB data transmission within a set of WB SPS / CG configuration messages 906.

[0099] In some aspects, the UE may transmit an indication of at least one timing gap associated with at least one of a first operating mode and a second operating mode. In some aspects, the UE may transmit at least one of the following: a second indication of a first minimum timing gap associated with a handover from the first operating mode to the second operating mode; a third indication of a second minimum timing gap associated with a handover from the second operating mode to the first operating mode; a fourth indication of a third minimum timing gap associated with a handover from data transmission to reference signal transmission (where the third data bandwidth associated with data transmission is less than the third reference signal bandwidth associated with reference signal transmission); or a fifth indication of a fourth minimum timing gap associated with a handover from reference signal transmission to data transmission (where the third data bandwidth associated with data transmission is less than the third reference signal bandwidth associated with reference signal transmission). For example, referencing... Figure 6 and Figure 9 UE 904 can send a set of minimum time slots (e.g., within the set of WB SPS / CG configuration messages 906) Figure 6 An indication of one or more minimum time intervals among T1, T2, T3 and / or T4.

[0100] At point 1006, the UE can detect the first trigger condition. In some aspects, the first trigger condition may be related to the energy available at the UE. For example, 1006 may be determined by... Figure 14The application processor 1406, cellular baseband processor 1424, transceiver 1422, antenna 1480, and / or WB to NB mode adjustment component 198 perform the operation. In some aspects, the first trigger condition may be associated with the available battery power at the UE being lower than a threshold power amount. In some aspects, the first trigger condition may be associated with the ECHR at the UE. In some aspects, the first trigger condition may be associated with both the available battery power at the UE and the ECHR at the UE. For example, refer to... Figure 8 and Figure 9 UE 904 can detect a triggering event at 910 (or 932), which can be based on one or more thresholds associated with ECHR and / or storage energy, such as regarding Figure 8 As described.

[0101] At 1008, based on the detection of a first trigger condition at the UE at 1006, the UE can send an indication to the network device for switching from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth. For example, 1008 can be... Figure 14 The application processor 1406, cellular baseband processor 1424, transceiver 1422, antenna 1480, and / or WB to NB mode adjustment component 198 are executed. In some aspects, at least one of the following occurs: the second data bandwidth is less than the first data bandwidth, and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth, and the second data bandwidth is less than the second reference signal bandwidth; and the first data bandwidth is less than the second data bandwidth, and the first reference signal bandwidth is greater than the first data bandwidth. In some aspects, if the second data bandwidth is less than the second reference signal bandwidth, the indication transmitted at 1008 may include an indication of the second data bandwidth from a set of one or more suitable or desired narrowband bandwidths. For example, referring to... Figure 9 UE904 may send a transition indication and / or request 912 or 934, which instructs base station 902 to send an updated SPS and / or CG timing configuration associated with the power saving operation mode and / or transition to (or from) the power saving operation mode.

[0102] In some aspects, the UE may receive an indication for activating a second reference signal bandwidth during a first time period. In some aspects, the UE may receive an indication for activating a second data bandwidth during at least a portion of the first time period. In some aspects, these indications may be received based on an indication sent at 1008 for switching from a first operating mode to a second operating mode. For example, reference... Figure 9UE 904 may receive BWP configuration indication 914, NB BWP reconfiguration indication 926 or BWP reconfiguration indication 936, which indicate the reference signal bandwidth and data bandwidth (such as the RS bandwidth and data bandwidth associated with one of the SPS and / or CG timing configurations 710, 720, 730 or 740) and the time of transition to different operating modes.

[0103] Based on the instruction sent at 1008, the UE can switch to a second operating mode and receive data signals via a second data bandwidth and reference signals via a second reference signal bandwidth. In some aspects, the reference signal may be an FMCW reference signal. In some aspects, the second reference signal bandwidth may be greater than the second data bandwidth, and the data signal may be associated with one or more periodic resource sets. In some aspects, each periodic resource set in the one or more periodic resource sets may include a first plurality of symbols, and the reference signal may be associated with one symbol in each periodic resource set of the one or more periodic resource sets or a second plurality of symbols in each periodic resource set of the one or more periodic resource sets.

[0104] In some aspects, the UE can process data signals and reference signals via a single baseband processor. In some aspects, the single baseband processor can be a first baseband processor capable of processing wideband data signals (e.g., if the second operating mode is the normal operating mode), or may be capable of (e.g., based on via such as...) Figure 6 The components of the local FMCW mixer 641 convert wideband FMCW reference signals to narrowband signals. A second baseband processor processes narrowband signals and wideband FMCW reference signals but cannot process wideband data signals (e.g., wideband data signals that are not easily converted to narrowband data signals without data loss). For example, refer to... Figure 6 and Figure 9 At 921 or 931, UE 904 can use the same baseband processor (such as power-saving mode receiver architecture 620) to handle WB FMCW RS transmission 918 and NB SPS / CG data transmission 920, WB FMCW RS transmission 928 and NB SPS / CG data transmission 930, or communication 938.

At 1102, the UE can transmit an indication of its ability to process at least one reference signal using a bandwidth greater than that of the associated data signal with the same baseband processor. For example, 1102 can be performed by...

Figure 9 For example, as part of configuring resources for communication, UE 904 may send an indication of the ability to use a power-saving operating mode associated with WB FMCW RS and NB data transmission within a set of WB SPS / CG configuration messages 906.

[0106] At 1104, the UE may transmit an indication of at least one timing interval associated with at least one of the first and second operating modes. For example, 1104 may be generated by...

[0107] At point 1106, the UE can detect the first trigger condition. In some aspects, the first trigger condition may be related to the energy available at the UE. For example, 1106 may be determined by...

[0109] At 1110, the UE can receive an indication for activating the second reference signal bandwidth during the first time period. At 1112, the UE can receive an indication for activating the second data bandwidth during at least a portion of the first time period. For example, 1110 and 1112 can be... Figure 14 The application processor 1406, cellular baseband processor 1424, transceiver 1422, antenna 1480, and / or WB to NB mode adjustment component 198 perform the operation. In some aspects, the indication received at 1110 and / or 1112 can be received based on the indication sent at 1108 for switching from a first operating mode to a second operating mode. For example, refer to Figure 9 UE 904 may receive BWP configuration indication 914, NB BWP reconfiguration indication 926 or BWP reconfiguration indication 936, which indicate the reference signal bandwidth and data bandwidth (such as the RS bandwidth and data bandwidth associated with one of the SPS and / or CG timing configurations 710, 720, 730 or 740) and the time of transition to different operating modes.

[0110] Based on the instruction transmitted at 1108 and / or received at 1110 and / or 1112, the UE may switch to a second operating mode and, at 1114, receive a data signal via a second data bandwidth and a reference signal via a second reference signal bandwidth. In some aspects, the reference signal may be an FMCW reference signal. For example, 1114 may be...

[0116] In some aspects, the network device may send an indication for activating the second reference signal bandwidth during a first time period. In some aspects, the sent indication may be received based on an indication received at 1206 for switching from a first operating mode to a second operating mode. For example, referring to...

At 1302, the network device can receive from the wireless device an indication of the wireless device's ability to process at least one reference signal using the same baseband processor with a bandwidth greater than that of the associated data signal. For example, 1302 can be performed by... Figure 15 The CU processor 1512, DU processor 1532, RU processor 1542, transceiver 1546, antenna 1580, and / or WB to NB mode adjustment assembly 199 perform this. In some aspects, at least one reference signal may be an FMCW reference signal. (Refer to...)

[0120] At 1304, the network device can receive an indication of at least one timing interval associated with at least one of a first operating mode and a second operating mode. For example, 1304 can be... Figure 15The CU processor 1512, DU processor 1532, RU processor 1542, transceiver 1546, antenna 1580, and / or WB to NB mode adjustment component 199 are executed. In some aspects, the network device may receive at least one of the following: a second indication of a first minimum timing gap associated with a switch from a first operating mode to a second operating mode; a third indication of a second minimum timing gap associated with a switch from a second operating mode to a first operating mode; a fourth indication of a third minimum timing gap associated with a switch from data transmission to reference signal transmission (where the third data bandwidth associated with data transmission is less than the third reference signal bandwidth associated with reference signal transmission); or a fifth indication of a fourth minimum timing gap associated with a switch from reference signal transmission to data transmission (where the third data bandwidth associated with data transmission is less than the third reference signal bandwidth associated with reference signal transmission). For example, refer to Figure 6 and Figure 9 Base station 902 can receive a set of minimum time intervals (e.g., within the set of WB SPS / CG configuration messages 906) Figure 6 An indication of one or more minimum time intervals among T1, T2, T3 and / or T4.

[0121] The wireless device can detect a first condition related to the energy available at the wireless device. In some aspects, the first condition related to the energy available at the network device can be associated with the battery power available at the network device being below a threshold power amount. In some aspects, the first condition related to the energy available at the network device can be associated with the ECHR (Electronic Energy Recovery Rate) at the network device. In some aspects, the first condition related to the energy available at the network device can be associated with both the battery power available at the network device and the ECHR at the network device. For example, refer to... Figure 8 and Figure 9 UE 904 can detect a triggering event at 910 (or 932), which can be based on one or more thresholds associated with ECHR and / or storage energy, such as regarding Figure 8 As described.

[0122] At 1306, based on a first condition detected by the wireless device related to the energy available at the wireless device, the network device can receive from the wireless device an instruction to switch from a first operating mode associated with a first data bandwidth and a first reference signal bandwidth to a second operating mode associated with a second data bandwidth and a second reference signal bandwidth. For example, 1306 may be... Figure 15The CU processor 1512, DU processor 1532, RU processor 1542, transceiver 1546, antenna 1580, and / or WB to NB mode adjustment component 199 perform this. In some aspects, at least one of the following occurs: the second data bandwidth is less than the first data bandwidth, and the second reference signal bandwidth is greater than the second data bandwidth; the first data bandwidth is less than the first reference signal bandwidth, and the second data bandwidth is less than the second reference signal bandwidth; and the first data bandwidth is less than the second data bandwidth, and the first reference signal bandwidth is greater than the first data bandwidth. In some aspects, if the second data bandwidth is less than the second reference signal bandwidth, the indication received at 1306 may include an indication of the second data bandwidth from a set of one or more suitable or desired narrowband bandwidths. For example, referring to... Figure 9 Base station 902 may receive a transition indication and / or request 912 or 934, which instructs base station 902 to send an updated SPS and / or CG timing configuration associated with a power-saving operation mode and / or transition to (or from) a power-saving operation mode.

[0123] At point 1308, the network device may send an indication for activating the second reference signal bandwidth during the first time period. At point 1310, the network device may send an indication for activating the second data bandwidth during at least a portion of the first time period. For example, points 1308 and 1310 may be... Figure 15 The CU processor 1512, DU processor 1532, RU processor 1542, transceiver 1546, antenna 1580, and / or WB to NB mode adjustment component 199 perform this. In some aspects, the instruction transmitted at 1308 and / or 1310 can be received based on the instruction received at 1306 for switching from a first operating mode to a second operating mode. For example, refer to Figure 9 Base station 902 may send BWP configuration indication 914, NB BWP reconfiguration indication 926 or BWP reconfiguration indication 936, which indicate the reference signal bandwidth and data bandwidth (such as the RS bandwidth and data bandwidth associated with one of the SPS and / or CG timing configurations 710, 720, 730 or 740) and the time to switch to different operating modes.

[0124] Based on the instruction received at 1306 and / or transmitted at 1308 and / or 1310, the network device may switch to a second operating mode and, at 1312, transmit a data signal via a second data bandwidth and a reference signal via a second reference signal bandwidth. In some aspects, the reference signal may be an FMCW reference signal. For example, 1312 may be... Figure 15The CU processor 1512, DU processor 1532, RU processor 1542, transceiver 1546, antenna 1580, and / or WB to NB mode adjustment component 199 perform the operation. In some aspects, the second reference signal bandwidth may be greater than the second data bandwidth, and the data signal may be associated with one or more periodic resource sets. In some aspects, each periodic resource set in one or more periodic resource sets may include a first plurality of symbols, and the reference signal may be associated with one symbol in each periodic resource set of one or more periodic resource sets or a second plurality of symbols in each periodic resource set of one or more periodic resource sets.

[0125] In some respects, wireless devices may process data signals and reference signals via a single baseband processor. In some respects, the single baseband processor may be a first baseband processor capable of processing wideband data signals (e.g., if the second operating mode is the normal operating mode), or a second baseband processor capable of processing narrowband signals (and wideband FMCW reference signals) but not wideband signals.
