Description

Technical Field

[0001] The present disclosure relates generally to communication systems and, more particularly, to methods of wireless communications including wireless energy transmission. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. 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.

[0003] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third 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). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0004] The following presents a summary of one or more aspects in order to provide a basic understanding of these aspects. This summary is not an extensive review of all envisioned aspects. This summary is neither intended to identify the key or important elements of all aspects, nor to describe the scope of any or all aspects. Its only purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description presented later.

[0005] In one aspect of the present disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may include a user equipment, an energy transmitter, and a network node. In one aspect, a UE may be configured to receive a first energy signal in a first frequency band or a first CC dedicated to a wireless energy transmission (WET) from one or more frequency bands or one or more component carriers (CCs) associated with the WET, and based on receiving the first energy signal in the first frequency band dedicated to the WET, a power collection circuit is used to collect radio frequency energy from the first energy signal. On the other hand, the energy transmitter may be configured to obtain an indication of a first frequency band or a first CC dedicated to the WET from one or more frequency bands or one or more CCs associated with the WET, and send a first energy signal to the UE in the first frequency band dedicated to the WET. On the other hand, the network entity may be configured to: configure a first frequency band or a first CC dedicated to the WET from one or more frequency bands or one or more CCs associated with the WET, so that the network entity sends a first energy signal to the UE in the first frequency band dedicated to the WET; configure at least one WIT frequency band including one or more of a DL WIT frequency band carrying a downlink (DL) channel, a UL WIT frequency band carrying an uplink (UL) channel, or a SL WIT frequency band carrying a sidelink (SL) channel, so that the UE communicates data signals with the network node or another UE; and communicate the data signal with the UE in the at least one WIT frequency band.

[0029] Some passive devices may include power collection circuits to collect radio frequency (RF) energy from ambient radio signals. However, the ambient radio signals of wireless communications may not be strong enough to support energy collection passive devices (or semi-passive devices with energy storage) within a wireless network. According to some aspects of the present disclosure, a dedicated wireless energy transmission band or subchannel may be configured, and an energy transmitter may be configured to send an energy signal to a passive device with a power collection circuit to turn on the passive device and communicate with the passive device. The various aspects presented herein can help provide a reliable energy source for such energy collection devices. A network entity may send energy signals and / or communication signals. The various aspects presented herein enable collaborative energy transfer signaling between a network entity and a UE to provide more continuous energy transfer transmission to one or more devices.

[0030] The detailed description set forth below in conjunction with the accompanying drawings is a description of various configurations and does not represent the only configurations with which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments 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 blurring these concepts.

[0031] Several aspects of the telecommunication system are also presented with reference to various apparatuses and methods. These apparatuses 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 can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] As an example, an element or any part of an element or any combination of elements can be implemented as a "processing system", which 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 chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic pieces, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout the present disclosure. One or more processors in a 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 meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, or any combination thereof.

[0033] Therefore, in one or more example aspects, specific implementations and / or use cases, the described functions may be implemented with hardware, software, or any combination thereof. In the case of being implemented with software, the functions may be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available medium that can be accessed by 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 disk storage, magnetic disk storage, 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 that can be accessed by a computer.

[0034] Although various aspects, specific implementations and / or use cases are described in this application by the illustration of some examples, additional or different aspects, specific implementations and use cases may be generated in many different arrangements and scenarios. The various aspects, specific implementations and / or use cases described herein can be implemented across many different platform types, devices, systems, shapes, sizes and packaging arrangements. For example, aspects, specific implementations and / or use cases can be generated via integrated chip specific implementations and other devices based on non-module components (e.g., end-user equipment, vehicles, communication equipment, computing equipment, industrial equipment, retail / purchase equipment, medical equipment, artificial intelligence (AI) enabled devices, etc.). Although some examples may be specifically for use cases or applications, or may not be specifically for use cases or applications, the described examples may have a wide range of applicability. Aspects, specific implementations and / or use cases may be in the range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed or original equipment manufacturer (OEM) devices or systems in conjunction with one or more technologies herein. In some practical environments, the equipment in conjunction with the various aspects and features described may also include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / accumulators, etc.) The various techniques described herein can be practiced in a wide variety of devices of various sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc.

[0035] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. 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 functions) can be implemented in an aggregated architecture or a decomposed architecture. For example, a BS (such as a Node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a transmit receive point (TRP) or a cell, etc.) can be implemented as an aggregated base station (also referred to as an independent BS or a monolithic BS) or a decomposed base station.

[0036] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack physically or logically distributed between 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 in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0037] Base station operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configurations such as those initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Various units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0038] Figure 1 1 is a diagram 100 illustrating an example of a wireless communication system and an access network. The illustrated wireless communication system includes a disaggregated base station architecture. The disaggregated base station architecture may include one or more CUs 110 that may 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. The CU 110 may communicate with one or more DUs 130 via corresponding midhaul links, such as an F1 interface. The DU 130 may communicate with one or more RUs 140 via corresponding fronthaul links. The RU 140 may communicate with corresponding UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 140.

[0039] Each of the units (i.e., CU 110, DU 130, RU 140, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive or send signals to one or more of the other units on a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0040] In some aspects, CU 110 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 110. CU 110 may be configured to handle user plane functions (i.e., central unit-user plane (CU-UP)), control plane functions (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 110 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 110 may be implemented to communicate with DU 130 for network control and signaling.

[0041] DU 130 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 140. In some aspects, 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 and demodulation, etc.) depending at least in part on a functional split such as that defined by 3GPP. In some aspects, DU 130 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 130 or with control functions hosted by CU 110.

[0042] The lower layer functions may be implemented by one or more RUs 140. In some deployments, the RU 140 controlled by the 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, etc.), or both, based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, the RU 140 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, 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 may enable the implementation of the DU 130 and the CU 110 in a cloud-based RAN architecture (such as a vRAN architecture).

[0043] The SMO framework 105 may be configured to support RAN deployment and provisioning of non-virtualized network elements 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, which may be managed via an operation 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 lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an 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 specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 111) via the O1 interface. Additionally, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs 140 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0044] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) / machine learning (ML) (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or in communication with the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 110, one or more DUs 130, or both, and the O-eNB with the near-RT RIC 125.

[0045] In some implementations, in order to generate an AI / ML model 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. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function 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 adjust RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0046] At least one of the CU 110, the DU 130, and the RU 140 may be referred to as a base station 102. Therefore, the base station 102 may include one or more of the CU 110, the DU 130, and the RU 140 (each component is indicated by a dotted line to indicate that each component may be included in the base station 102, or may not be included in the base station). The base station 102 provides an access point to the core network 120 for the UE 104. The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). Small cells include femto cells, pico cells, and micro cells. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a home evolved Node B (eNB) (HeNB), which may provide services to a restricted group referred to as a closed subscriber group (CSG). The communication link between RU 140 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to RU 140 and / or downlink (DL) (also known as forward link) transmission from RU 140 to UE 104. The communication link may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmission diversity. The communication link may be through one or more carriers. For each carrier allocated in a carrier aggregation of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 may use a spectrum of up to Y MHz (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz, etc.) bandwidth. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). The component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0047] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use 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). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, Bluetooth, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0048] Some UEs may be energy transmitters 104A that may transmit energy signals 156 to UE 104, and UE 104 may be energy receivers or passive devices having power harvesting circuits that may harvest radio frequency (RF) energy from energy signals 156 received from energy transmitter 104A. At least one dedicated frequency band or subchannel may be configured for energy transmitter 104A to transmit energy signals 156, and for UE 104 to receive energy signals 156 and harvest RF energy from received energy signals 156.

[0049] The wireless communication system may also include a Wi-Fi AP 150 that communicates with a UE 104 (also referred to as a Wi-Fi station (STA)) via a communication link 154, for example, in a 5 GHz unlicensed spectrum, etc. When communicating in an unlicensed spectrum, the UE 104 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0050] 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 identified as frequency range designations FRI (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 (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0051] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FRI characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6GHz-71GHz), FR4 (71GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0052] In view of the above, unless otherwise specifically stated, when the term "below 6 GHz" or the like is used in this document, it can broadly refer to frequencies that may be less than 6 GHz, may be within FR 1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, when the term "millimeter wave" or the like is used in this document, it can broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and / or FR5, or may be within the EHF band.

[0053] The base station 102 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and / or antenna arrays) to facilitate beamforming. The base station 102 may send 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 send 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 direction and transmit direction for each base station in the base station 102 / UE 104. The transmit direction and receive direction of the base station 102 may be the same or different. The transmit direction and receive direction of the UE 104 may be the same or different.

[0054] The base station 102 may include and / or be referred to as a gNB, a Node B, an 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 transmit receive point (TRP), a network node, a network entity, a network equipment, or some other suitable term. The base station 102 may be implemented as an integrated access 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 a RU, or as a disaggregated base station including one or more of a CU, a DU, and / or a RU. A set of base stations that may include disaggregated base stations and / or aggregated base stations may be referred to as a next generation (NG) RAN (NG-RAN).

[0055] 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. AMF 161 is a control node that handles signaling between UE 104 and 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 the generation of authentication and key agreement (AKA) credentials, user identity handling, access authorization, and subscription management. 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, in general, 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, LMF 166, positioning determination entity (PDE), serving mobile location center (SMLC), mobile positioning 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 positioning information. LMF 166 receives measurement results and auxiliary information from NG-RAN and UE 104 via AMF 161 to calculate the positioning of UE 104. NG-RAN may determine the positioning of UE 104 using one or more positioning methods. Positioning UE 104 may involve signal measurements, positioning estimates, and optional speed calculations based on these measurements. Signal measurements may be performed by UE 104 and / or serving base station 102. The measured signals may be based on a satellite positioning system (SPS) 170 (e.g., one or more of a global navigation satellite system (GNSS), a global positioning system (GPS), a non-terrestrial network (NTN), or other satellite positioning / location systems), LTE signals, wireless local area network (WLAN) signals, Bluetooth signals, a terrestrial beacon system (TBS), sensor-based information (e.g., an atmospheric pressure sensor, a motion sensor), an NR enhanced cell ID (NR E-CID) method, 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 one or more of other systems / signals / sensors.

[0056] Examples of UE 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as stations, mobile stations, subscriber stations, mobile units, subscriber units, wireless units, remote units, mobile devices, wireless devices, wireless communication devices, remote devices, mobile subscriber stations, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, user agents, mobile clients, clients, or some other suitable terminology. In some scenarios, the term UE may also be applied to one or more supporting devices, such as in a device cluster arrangement. One or more of these devices may access the network collectively and / or individually.

[0057] Reference again Figure 1In some aspects, the UE 104 may include a wireless energy receiving component 198 configured to receive a first energy signal in a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET, and based on receiving the first energy signal in the first frequency band dedicated to WET, collect radio frequency energy from the first energy signal using a power harvesting circuit. In some aspects, the energy transmitter 104A may include a wireless energy transmitting component 199A configured to obtain an indication of a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET, and transmit the first energy signal to the UE in the first frequency band dedicated to WET. In some aspects, the base station 102 may include: a wireless energy transmission component 199A, which is configured to obtain an indication of a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET, and send a first energy signal to the UE in the first frequency band dedicated to WET; or a wireless energy transmission configuration component 199B, which is configured to: configure the first frequency band or the first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET, so that the network entity sends the first energy signal to the UE in the first frequency band dedicated to WET; configure at least one WIT frequency band including one or more of a DL WIT frequency band carrying a DL channel, a UL WIT frequency band carrying a UL channel, or a SL WIT frequency band carrying a SL channel, so that the UE communicates a data signal with a network node or another UE; and communicate a data signal with the UE in at least one WIT frequency band. Although 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.

[0058] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG280 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or may be time division duplex (TDD), where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A , Figure 2CIn the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with 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 may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are both DL and both UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. The slot format is configured for the UE by a received slot format indicator (SFi) (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0059] FIG. 2A to FIG. 2D The frame structure is illustrated, and various aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 subframes of the same size (1ms). Each subframe may include one or more time slots. A subframe may also include a microslot, 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 conventional or extended. For a conventional CP, each time slot may include 14 symbols, and for an extended CP, each time slot may include 12 symbols. The symbol on the DL may be a CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) extended OFDM (DFT-s-OFDM) symbol (also known as a single carrier frequency division multiple access (SC-FDMA) symbol) (for power-limited scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the CP and parameter set. The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length / duration, which is equal to 1 / SCS.

[0060]

[0061]

[0062] For normal CP (14 symbols / slot), different parameter sets μ 0 to 4 allow 1, 2, 4, 8 and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Accordingly, for normal CP and parameter set μ, there are 14 symbols / slot and 2μ slots / subframe. The subcarrier spacing can be equal to 2μ*15kHz, where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=4 is 240kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example of a parameter set μ=2 with a normal CP of 14 symbols per slot and 4 slots per subframe is provided. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is about 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP may have a specific parameter set and CP (normal or extended).

[0063] A resource grid may be used to represent a frame structure. Each slot includes a resource block (RB) (also referred to as a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0064] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) (indicated as R for a particular configuration, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and a phase tracking RS (PT-RS).

[0065] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. A 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 a BWP may 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 a PDCCH monitoring opportunity on a CORESET, wherein 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. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and the radio frame timing. Based on the physical layer identity and the physical layer cell identity 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 referred to as an SS block (SSB)). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information such as system information blocks (SIBs) that are not sent via the PBCH, and paging messages.

[0066] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS may be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0067] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (Ri), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and / or negative ACKs (NACKs)). The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0068] Figure 3 370 is a block diagram of a base station 310 communicating 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 functions. 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 functions associated with broadcasting of 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 functions associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions associated with delivery 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 functions 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.

[0069] The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functions associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transmission channel, forward error correction (FEC) decoding / decoding of the transmission channel, interleaving, rate matching, mapping to the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 handles 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. Subsequently, each stream can be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived from reference signals and / or channel state feedback sent 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 for transmission using a corresponding spatial stream.

[0070] At the UE 350, each receiver 354Rx receives a signal through its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functions associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream to the UE 350. In the case where multiple spatial streams are to the UE 350, they can be merged into a single OFDM symbol stream by the RX processor 356. 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 point sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to controller / processor 359, which implements layer 3 and layer 2 functions.

[0071] The controller / processor 359 may 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 channels and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0072] Similar to the functions described in conjunction with DL transmission performed by the base station 310, the controller / processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0073] The TX processor 368 may use channel estimates derived by the channel estimator 358 from a reference signal or feedback sent by the base station 310 to select appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via corresponding transmitters 354Tx. Each transmitter 354Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0074] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to the RX processor 370.

[0075] The controller / processor 375 may 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 channels and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0076] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform a combined Figure 1 198. At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform a combined Figure 1 Various aspects of the wireless energy transmission component 199A.

[0077] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform a combined Figure 1 Various aspects of the wireless energy transmission configuration component 199B.

[0078] Figure 4 A diagram 400 of an RFID tag 402 receiving an energy transfer signal 406 from an RFID reader 404 is illustrated. Such an RFID tag 402 is an example of an energy receiver that can obtain energy from an energy transfer signal (or energy signal) from an energy transmitter (e.g., an RFID reader 404). The energy transfer signal 406 can be used in various industrial IoT (IIoT) applications. For example, RFID technology can be used for inventory / asset management inside and outside warehouses, network sensors in factories, logistics equipment, manufacturing environments, agricultural applications, smart homes, etc. RFID technology can also be deployed in association with cellular infrastructure for wireless applications. An RFID device may include a transponder (e.g., an RFID tag 402) that transmits an information-bearing signal, such as a backscatter modulated information signal 408, when receiving a signal from an RFID reader 404. That is, the RFID reader 404 can send an energy transfer signal 406 as well as an information signal to a passive RFID microchip (e.g., an RFID tag 402) operating without a battery source.

[0079] RFID tag 402 can be configured to operate with low operating expenditure (OPEX), low maintenance cost and / or increased life cycle without a battery source. Other types of RFID tags may include a battery source. For example, semi-passive RFID devices and active RFID devices may have a battery source, but may also be associated with higher costs. In the case where RFID reader 404 is able to provide sufficient received energy 410 to RFID tag 402, RFID tag 402 can collect received energy 410 to perform operations during the communication occasion, or can collect received energy 410 to charge an associated battery. Passive RFID tags can collect received energy 410 over the air to power the Tx / Rx circuit at RFID tag 402. The energy transfer signal 406 sent to RFID tag 402 can trigger a backscattered modulated information signal 408 from RFID tag 402. RFID tag 402 can absorb or reflect a signal from RFID reader 404 based on the information to be communicated between RFID tag 402 and RFID reader 404. In some cases, RFID tag 402 may include a reduced number of active RF components (eg, no active RF components). By increasing the coverage area of ​​energy transfer signal 406, RFID reader 404 and RFID tag 402 may communicate over a longer physical distance.

[0080] Wireless communication technologies associated with eMBB, URLLC, machine type communication (MTC), etc. may be supported for passive IoT devices. Passive IoT devices are energy receiving devices (such as Figure 4 405 in ). In the example, the RFID reader 404 may correspond to a base station or an entity at a base station, and the RFID tag 402 may correspond to or communicate with a UE. However, some wireless communication technologies may not support certain types of widespread RFID technologies, such as passive IoT devices used for asset management, logistics, warehousing, and manufacturing, etc. In other examples, the passive IoT devices may include timing devices, such as clocks, video equipment, household tools, construction tools, lighting systems, etc.

[0081] In some aspects, the wireless communication technology may support wireless energy transmission (WET) and / or wireless information transmission (WIT) to incorporate passive IoT devices into a wireless network. Using a cellular infrastructure, a base station / network entity may operate as an RFID reader 404 that sends an energy transfer signal 406 to an RFID tag 402 for communicating with a passive IoT device via RFID technology. The base station / network entity may provide energy to the passive IoT device via the energy transfer signal 406 (e.g., the energy transfer signal may correspond to 412a or 414) and may be configured to read / write information stored at the passive IoT device. The information-bearing signal may be reflected from the passive IoT device to the base station / network entity, which may read the reflected signal. For example, the base station / network entity may decode information included in an information-bearing signal (e.g., a backscatter modulated information signal 408) received from a passive IoT device (e.g., an RFID tag 402).

[0082] Figure 5 506. The power collection circuit 500 is a diagram of a power collection circuit. In an example, the power collection circuit may be included at an RFID tag and may include few or no active components. The power collection circuit may be configured to operate at low power during an energy transfer protocol for RF power collection. The energy transfer signal may be received by an antenna 502 and communicated to an impedance matching component 504. The impedance matching component 504 may be tuned to the impedance of the antenna 502 so that the input to the power collection component 506 may be based on the increased power from the impedance matching component. The output of the impedance matching component 504 may also be demodulated by a demodulator 512 and provided to a microcontroller unit (MCU).

[0083] The nonlinearity of the power collection component 506 may be generated at the output of the power collection component 506 based on the characteristics of the diode associated with the power collection component 506. For example, the power collection component 506 may include a diode that must receive a minimum voltage / power from the antenna 502 and the impedance matching component 504 in order to activate the diode. The minimum voltage / power input to the power collection component 506 to activate the diode may be greater than the power associated with the information signal. For example, the input power to the power collection component 506 may be greater than -20dBm, but in some cases, -10dBm may be the minimum power for activating the diode / power collection component 506. The power collection component 506 may be more efficient at lower frequencies when converting the energy transfer signal to power based on the capacitance and / or resistance of the diode at the power collection component 506. Compared to the energy transfer signal, the bits of the information signal may be decoded at a power input as low as -100dBm to -80dBm.

[0084] The regulator 508 may receive the output of the power collection component 506. The regulator 508 may adjust for nonlinearity of the power collection component 506 before providing the output of the power collection component 506 to the MCU 510. The MCU 510 may be configured to control a sensor 514 in communication with the MCU 510 based on the collected power and / or output a signal to a modulator 516 that modulates the output signal as feedback to the antenna 502 and / or the impedance matching component 504.

[0085] The power collection circuit may include a boost converter 520 to receive the output of the power collection component 506. The boost converter may increase (or boost) the voltage of the output of the power collection component. The output of the boost converter 520 having a boosted voltage may be supplied to an energy storage 522. The energy storage 522 may receive the boosted voltage and store energy collected by the power collection component 506. The energy storage 522 may provide the stored power to other components that may need to be turned on without the output of the power collection component 506. For example, the power collection circuit may determine that the energy signal received from the energy transmitter fails to meet a threshold value of the energy transmitter. In the event that the energy density of the received energy signal is lower than the turn-on voltage, the energy receiver may use the power stored in the energy storage to send an indication to the energy transmitter that the energy signal received from the energy transmitter fails to meet the threshold value.

[0086] In some aspects, a passive IoT device may be incorporated into a wireless network, and the ambient RF signal may not provide sufficient power density to send an energy signal having a power density greater than or equal to a threshold to activate (or switch on) the power harvesting circuit. In one example, the power density of an ambient RF signal (e.g., a digital television signal (DTV), a global system for mobile communications (GSM), 3G, or Wifi) may be less than 10 nW / cm 2- Here, the power level may vary over time and depend on the location.

[0087] Wireless communication technology may support wireless energy transmission (WET) and / or wireless information transmission (WIT) to incorporate passive IoT devices into wireless networks. That is, dedicated frequency bands may be configured for wireless energy transmission to PIoT applications. Frequency bands associated with WET may be reserved for at least one of WET, WIT, or WET+WIT. Dedicated frequency bands may provide energy coverage for pervasive or permanent wireless powered IoT devices.

[0088] Figure 6A WET band set 600 is illustrated. Here, a WET band set may refer to a band set or CC set dedicated to sending and receiving energy signals for WET operation. The WET band set 600 may include one or more WET bands or CCs. A network node may send an energy signal in one or more CCs in the CCs of the WET band set 600, and a UE may collect energy from the energy signal received in the WET band set 600. In one aspect, each WET band in the WET band set may be configured to have a relatively narrow bandwidth. For example, each WET band in the WET band set may be configured with a single carrier or a bandwidth of several kHz.

[0089] The WET band set 600 may include an anchor WET band 610. The anchor WET band 610 may be defined or configured to power up for UE to receive an energy signal. The anchor WET band 610 may be configured as a public WET band for a WET device (e.g., an energy receiver), which may, for example, support WET operations across multiple cells in common. In one aspect, the anchor WET band 610 may be supported by all WET devices / cells (e.g., IoT devices) configured with WET, and other WET bands (e.g., the first WET band 620 and the second WET band 630) may be defined or configured per cell. For example, the first cell may have a WET band 1620 configured as energy transfer, but not a WET band 2630, in addition to the anchor WET band 610. The second cell may include a WET band 2630 configured for energy transfer and does not include a WET band 1. The WET device may initially collect energy from the anchor WET band, and then identify other WET bands based on signaling or measurement for a specific cell. That is, the WET device may initially receive an energy signal on the anchor WET band to turn on an energy collection circuit (e.g., power collection circuit 500), and identify other WET bands (e.g., first WET band 620 or second WET band 630). In one example, the anchor WET band 610 may include an indication of a frequency band associated with the first WET band 620 or the second WET band 630, and the WET device may identify the first WET band 620 and the second WET band 630 based on the indication included in the anchor WET band 610. On the other hand, a frequency offset relative to the anchor WET band 610 may be used to indicate the WET band 620 or the second WET band 630. The WET device may identify the first WET band 620 and the second WET band 630 based on an indication of a frequency offset relative to the anchor WET band 610. The WET device may select one of the first WET band 620 or the second WET band 630 with relatively higher energy, and match the impedance of the power harvesting circuit of the WET device based on the relatively higher energy. For example, the WET device may measure that the energy signal received on the first WET band 620 has a relatively higher energy measurement than the second WET band 630, and the WET device may tune the impedance circuit or select the impedance circuit matching the first WET band 620 to receive the energy signal in the first WET band 620 and harvest radio frequency (RF) energy.

[0090] A WET band or WET CC may be associated with a WET frequency. Here, a WET frequency may refer to a certain amount of frequency reserved for or dedicated to sending and receiving energy signals for WET operation. A WET frequency may be associated with an anchor WET band or an anchor WET CC, and the WET frequency may be configured for a wireless power supply device so that the wireless power supply device can optimize its power collection circuit to a selected WET band (e.g., an impedance matching network). A WET device (e.g., an energy receiver) may collect RF energy from one or more WET bands or CCs depending on the capabilities of the UE. In one aspect, a WET device may not expect to receive information from an energy signal in a WET band or decode the information.

[0091] Fig. 7A The bandwidth 710 of the WET frequency band 700 is illustrated. The WET frequency band 700 dedicated to transmitting and receiving energy signals for WET operation and the WET frequency of the WET frequency band 700 (which may be a frequency of a reserved amount for WET) may be associated with the transmission bandwidth 710. In some aspects, the transmission bandwidth 710 of the WET frequency band 700 may include one or more WET sub-channels. The bandwidth of each of the one or more WET sub-channels or the bandwidth of a certain number of WET sub-channels may be configured based on the transmission bandwidth 710 of the WET frequency band 700.

[0092] The energy transmitter may select one or more WET subchannels to send an energy signal to the energy receiver. In one example, the energy transmitter may select the first WET subchannel 712 to send an energy signal to the energy receiver. In another example, the first WET subchannel 712 may be configured as a default WET subchannel for the energy transmitter and the energy receiver to send and receive energy signals.

[0093] In one aspect, the power spectral density (PSD) of the energy signal transmitted in one or more WET sub-channels of the WET frequency band 700 may be greater than the PSD of the energy signal transmitted in the WET frequency band 700. That is, the bandwidth of the first WET sub-channel 712 may be smaller than the transmission bandwidth 710 of the WET frequency band 700, and the PSD of the energy signal transmitted in the first WET sub-channel 712 of the WET frequency band 700 may be greater than the PSD of the energy signal transmitted in the WET frequency band 700.

[0094] On the other hand, the energy transmitter may be configured to hop or switch from one subchannel to another subchannel when some served energy receivers (ERs) are in poor positioning (e.g., due to multipath reflections). That is, the energy transmitter may be configured to serve multiple energy receivers using the first WET subchannel 712, and each of the multiple energy receivers may have a different channel quality associated with the first WET subchannel 712. In the case where one or more energy receivers indicate that the energy signal received in the first WET subchannel 712 is less than a threshold, the energy transmitter may determine to hop or switch from the first WET subchannel 712 to the second WET subchannel 714. In one example, the energy transmitter may select the second WET subchannel 714 based on receiving an indication from one or more energy receivers that the energy signal received in the first WET subchannel 712 is less than a threshold, and send an indication of the second WET subchannel 714 to the one or more energy receivers. In another example, the energy transmitter may be configured to use the second WET subchannel 714 in the case of frequency hopping or switching, and switch from the first WET subchannel 712 to the second WET subchannel 714.

[0095] The energy transmitter may adjust or define at least one transmission parameter of the energy signal transmitted in the WET band 700 according to at least one regional specification or base station category (e.g., specifications of wireless communication operation, energy transmitter, or network node including base station). In one example, the energy transmitter may define the effective isotropic radiated power (EIRP) and / or PSD of the energy signal transmitted in the WET band 700 based on the specifications of the wireless communication operation, energy transmitter, or network node including base station.

[0096] Figure 7B An adjacent channel leakage power ratio (ACLR) of a WET band 730 is illustrated. The WET band 730 may cause out-of-band emissions (e.g., spectrum emission mask, operating band unwanted emissions (OBUE), etc.) and spurious emissions. That is, the transmission of energy signals in the WET band 730 may cause leakage power in adjacent data channels for transmitting data signals, which may affect data transmission in adjacent channels. Here, a frequency band or CC associated with a data channel (e.g., at least one of a UL channel, a DL channel, or a sidelink (SL) channel) may be referred to as a radio access technology (RAT) band 752 or a RAT CC.

[0097] In one aspect, at least one transmission parameter of the energy signal transmitted in the WET band 730 may be configured based on the ACLR specification of the WET band (e.g., the first ACLR 740 and the second ACLR 742). That is, the energy transmitter may be configured to determine at least one transmission parameter of the energy signal transmitted in the WET band 730 based on the ACLR specification of the WET band 730, so that the power leaked into the RAT band 752 may not exceed a threshold value based on the first ACLR 740 and the second ACLR 742 and the parameters of the RAT band 752.

[0098] In one example, the ACLR specification of the WET band 730 may be based on an offset frequency 750 between at least one RAT band 752 and the WET band 730. That is, the ACLR specification (e.g., the first ACLR 740 and the second ACLR 742) associated with the energy signal of the WET band 730 may be defined or identified based on the offset frequency 750 between the WET band 730 and the RAT band 752.

[0099] In another example, the ACLR specification of the WET band 730 may be configured differently based on the RAT specification of the RAT band 752. That is, the ACLR specification of the WET band 730 may be defined depending on the RAT specification of the adjacent data channel (eg, NR, LTE, etc.).

[0100] On the other hand, the WET band may have relaxed out-of-band emission specifications for adjacent bands. That is, since the WET band 730 may be configured to transmit energy signals to transfer RF power rather than being configured for data transmission, adjacent channels may be configured with relaxed specifications for out-of-band emissions of the WET band. For example, the RAT band 752 may not have an ACLR specification for the WET band 730, and a network node that transmits a data signal in the RAT band 752 may ignore the impact of the data signal transmitted in the RAT band 752 on the WET band 730.

[0101] Figure 7C A WET band 770 and a RAT band 780 are illustrated. The WET band 770 may be associated with a WET frequency, which may refer to a frequency allocated a reserved amount for the WET band 770. The RAT band 780 may refer to a frequency band or CC for communicating a data channel (e.g., at least one of a UL channel, a DL channel, or a SL channel) between network entities.

[0102] The transmission of data signals or channels in the RAT band 780 may cause out-of-band emissions in the WET band 770. The RAT band 780 may have reduced or fewer specifications regarding out-of-band emissions in the WET band 770 caused by data signals in the RAT band 780. That is, the energy signal transmitted in the WET band 770 does not carry a data signal, and therefore, the interference leakage into the WET band 770 caused by the RAT band 780 may not be significant for WET operation. Therefore, the RAT band 780 may be configured to less consider the impact of the data signal transmitted in the RAT band 780 on the WET band 770. In some examples, the RAT band 780 may be configured with an ACLR specification, a windowing and / or filtering specification, or an intermodulation suppression to reduce power leakage into adjacent bands, and the configured ACLR specification, the windowing and / or filtering specification, or the intermodulation suppression may be relaxed or not applied with respect to the adjacent WET band 770.

[0103] In one aspect, the RAT band 780 may have a relaxed specification for transmissions into the WET band 770 by the adjacent RAT band 780. For example, the RAT band 780 adjacent to the WET band 770 may be configured to have a relaxed ACLR specification or no ACLR specification for transmissions of other channels into the WET band 770. In another aspect, a shorter RF filter may be applied to the adjacent RAT band 780 or to the signals of the WET band 770. In another aspect, a first windowing / filtering with higher transmissions in the WET band 770 and a second windowing / filtering with smaller transmissions in the non-WET band may be applied to the RAT band 780.

[0104] On the other hand, in the case where the intermodulation products fall into the WET band, due to nonlinearity, relaxed intermodulation suppression may be applied to the RAT band 780. Intermodulation suppression may include controlling power amplification and filtering to reduce intermodulation products entering adjacent bands. Therefore, the relaxed intermodulation products entering the adjacent WET band 770 may be applied to the adjacent RAT band 780 or not.

[0105] On the other hand, the RAT band 780 adjacent to the WET band 770 may perform multi-band transmission to achieve better emission suppression. For example, the network node may transmit a data signal S1(t) and a mitigation signal S2(t), wherein the data signal S1(t) may be a data signal transmitted in the RAT band 780, and the mitigation signal S2(t) may be transmitted in the WET band S2(t). Here, the mitigation signal S2(t) may be designed or optimized to minimize out-of-band emissions entering frequencies between the RAT band 780 and the WET band 770, or to eliminate / minimize total out-of-band emissions of the data signal S1(t) outside the frequency band of the RAT band 780.

[0106] In some aspects, one or more energy transmitters may access a WET frequency band (e.g., WET frequency band 700, 730, or 770) and / or a WET subchannel of a WET frequency band (e.g., the first WET subchannel 712 or the second WET subchannel 714). Various implementations may be configured for one or more energy transmitters to select a WET frequency band and / or a WET subchannel of a WET frequency band to transmit an energy signal to an associated WET device (e.g., an energy receiver).

[0107] In one aspect, access to the WET band / subchannel may be restricted for one or more energy transmitters and energy receivers. A network including a base station or a network node may reserve some WET bands / subchannels for dedicated energy signal transmission (e.g., a set of energy signals with a configuration waveform and / or power level for one or more groups of energy receivers). The WET band / subchannel reserved for dedicated energy signal transmission may be accessed by a configured energy transmitter (e.g., a network node, a base station, such as a gNB, an authenticated ET, or an ET scheduled by a gNB). In one example, an ET may receive a grant to transmit an energy signal on a WET band / subchannel for a certain duration and at a power level indicated in a grant received from a network node. In another example, an energy transmitter may use a dedicated reserved signaling resource or use a message (e.g., NR, LTE, SL, etc.) to send a message to a network node to reserve the WET band / subchannel.

[0108] On the other hand, one or more energy transmitters and energy receivers can access the WET band / subchannel without restriction. That is, one or more energy transmitters and energy receivers can access the WET channel at any time they need. In one example, the energy transmitter can be configured to receive a request from one or more energy receivers, and send an energy signal on the WET band / subchannel based on receiving a request from one or more energy receivers. In another example, the energy transmitter can also use the WET band / subchannel for out-of-band emission suppression. That is, the energy transmitter (or the network entity that sends the data signal) can be configured to send a mitigation signal in the WET band / subchannel to suppress the out-of-band emission caused by sending the data signal.

[0109] On the other hand, access to the WET band / subchannel can be based on a first-before-special (LBT) procedure. That is, the energy transmitter can perform the LBT procedure on the WET band / subchannel to detect the energy level of the WET band / subchannel, thereby determining whether the WET band / subchannel is used by another energy transmitter to send an energy signal. In the case where the detected energy level is less than a threshold, the energy transmitter can access and send an energy signal at a power level that can be determined by energy detection. That is, based on determining that the WET band / subchannel is not used by another energy transmitter based on energy detection, the energy transmitter can access the WET band / subchannel to send an energy signal. The power level of the energy signal can be determined based on energy detection.

[0110] One example of energy detection may be performed in a guard band of a WET band (i.e., measuring out-of-band emissions in the guard band caused by energy signals in the WET band). Another example of energy detection may be performed for the entire WET band. Another example of energy detection may be performed for each WET subchannel. In another example, the above examples of energy detection may be combined, and WET band / subchannel access may be determined based on one or more energy detection results of the combined examples of energy detection.

[0111] Fig. 8A , Figure 8B , Figure 8C and Fig.8D Examples 800, 820, 840, and 860 of WET bands / sub-channels and wireless information transmission (WIT) bands / sub-channels are illustrated. Fig. 8A A first example 800 is illustrated that includes a dedicated WET band / subchannel 802 and a dedicated WIT band / subchannel 804. In one aspect, TDD may be performed on the WET band / subchannel 802 and the WIT band / subchannel 804. That is, the WET band / subchannel 802 and the WIT band / subchannel 804 may be separated in time by a time gap 806 (which may be referred to as time division), and transmissions of the WET band / subchannel 802 and transmissions of the WIT band / subchannel 804 may not overlap each other in the time domain.

[0112] Figure 8B A second example 820 including a dedicated WET band 822 and a dedicated WIT band 824 is illustrated. Here, the WET band 822 and the WIT band 824 may be FDDed. That is, the WET band 822 and the WIT band 824 may be transmitted in different frequency bands. In one aspect, a duplex gap 826 may be configured (e.g., per-band) between the WET band 822 and the WIT band 824. In one example, a UE supporting WET operation may have different antennas configured for power collection from the WET band 822 and for transmitting / receiving information in the WIT band 824.

[0113] On the other hand, the UL WIT band and the DL WIT band may be TDDed. That is, the WET band and the WIT band may be FDDed with a duplex gap 826 between the WET band 822 and the WIT band 824, and the UL WIT band and the DL WIT band may be TDDed within the WIT band 824. That is, the UL WIT band and the DL WIT band may be configured to overlap in the frequency domain but not overlap in the time domain (e.g., transmitted in different time periods).

[0114] Figure 8C A third example 840 is illustrated that includes a dedicated WET and DL WIT band 842 that may overlap with a DL WIT band and a dedicated UL WIT band 844. Here, the WET band 842 may be used to transmit a DL channel including a DL signal, while the UL WIT band 844 may be used for UL data transmission. A duplex gap 826 may be configured between the WET and DL WIT band 842 and the UL WIT band 824 (e.g., in a per-band manner).

[0115] Fig.8D A fourth example 860 is illustrated including a dedicated WET band / subchannel 862, a dedicated DL WIT band / subchannel 866, and a dedicated UL WIT band / subchannel 864. Here, a guard band 863 between the WET band / subchannel 862 and the DL WIT band / subchannel 866 is used for interference leakage from the WET band / subchannel 862 to the DL WIT band / subchannel 866. The guard band 863 may be configured to be smaller so that the WET band / subchannel 862 and the DL WIT band / subchannel 866 can communicate using the same antenna at the UE.

[0116] On the other hand, the WET band and the WIT band may be configured in different subchannels in the same frequency band. That is, a single frequency band including a plurality of subchannels may be configured with a first subchannel set configured as a WET subchannel and a second subchannel set configured as a WIT subchannel. At least one guard band may be defined between the WET subchannel and the WIT subchannel.

[0117] In one example, FDD may be performed on the DL WIT subchannel and the UL WIT subchannel. That is, the DL WIT subchannel and the UL WIT subchannel may be allocated in different subchannels with a guard band between the DL WIT subchannel and the UL WIT subchannel. In another example, TDD may be performed on the DL WIT subchannel and the UL WIT subchannel. That is, the DL WIT subchannel and the UL WIT subchannel in the WIT subchannel may overlap in the frequency domain, but not in the time domain (e.g., transmitted in different time periods).

[0118] Fig. 9 900 is a call flow chart of a method of wireless communication. The call flow chart 900 may include a UE 902, an energy transmitter 903, and a network node 904 configured to support WET operation. Here, the UE 902 may be an energy receiver including a power collection circuit, and the energy transmitter 903 may be another UE or a network node (including the network node 904). In some aspects, a dedicated wireless energy transmission band or subchannel may be configured, and the energy transmitter 903 may be configured to send an energy signal to the UE 902 to connect the UE 902 and communicate with the UE. The network node 904 may configure at least one dedicated WET band / subchannel for the UE 902 and the energy transmitter 903. The energy transmitter 903 may send an energy signal to the UE 902 on at least one dedicated WET band / subchannel. The UE 902 may use the power collection circuit to collect RF energy from the energy signal received on at least one dedicated WET band / subchannel, and communicate a data signal with the network node 904.

[0119] The network node 904 may configure a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET, so that the network entity sends a first energy signal to the UE 902 in the first frequency band dedicated to WET.

[0120] At 905, the energy transmitter 903 may obtain an indication of a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET. Here, a guard band between each subchannel of the first frequency band dedicated to WET, the first frequency band dedicated to WET, or the first frequency band dedicated to WET may be configured. 907 may include 906, 908, 910, and 911.

[0121] At 906, the UE 902 may send a WET request to send a first energy signal in a first frequency band to at least one network entity. Here, the at least one network entity may be an energy transmitter 903 or a network node 904. The energy transmitter 903 may receive a WET request to send a first energy signal from the UE 902. The network node 904 may receive the WET request from the UE 902. A grant to the network entity to send the first energy signal on the first frequency band may be sent based on the WET request received from the UE 902.

[0122] At 908, the energy transmitter 903 may send a message to the network node 904 to reserve the first frequency band for sending the first energy signal. In one aspect, the message to reserve the first frequency band may be sent based on receiving the WET request from the UE 902 at 906. The network node 904 may receive the message from the energy transmitter 903 to reserve the first frequency band for sending the first energy signal.

[0123] At 910, the network node 904 may send a grant to send a first energy signal on a first frequency band from the network node 904. The energy transmitter 903 may receive a grant to send the first energy signal on the first frequency band from the network node 904. In one aspect, the grant may be received based on a message to reserve the first frequency band sent to the network node 904 at 908. In another aspect, the grant may be based on a WET request received from the UE 902 at 906.

[0124] At 911, the energy transmitter 903 may perform energy detection in the first frequency band. Here, at 914, a first energy signal may be transmitted in the first frequency band based on the result of the energy detection in the first frequency band being less than or equal to a threshold.

[0125] At 912, the network node 904 or the energy transmitter 903 may send a grant or WET instruction to send the first energy signal from the energy transmitter 903 to the UE 902. The UE 902 may receive a WET instruction for receiving the first energy signal in the first frequency band from the network entity. Here, the network entity may include the energy transmitter 903 or the network node 904. The first energy signal may be received in the first frequency band at 914 based on the received WET instruction. The grant or WET instruction may include that at least one configuration of the first energy signal is based on the first frequency band. In one aspect, at least one configuration of the first energy signal may include an EIRP or PSD of the first energy signal.

[0126] At 914, the energy transmitter 903 may send a first energy signal in a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET. The first energy signal may be sent in the first frequency band based on receiving a grant from the network node 904 at 910 or receiving a WET request from the UE 902 at 906. The UE 902 may receive the first energy signal in a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET. The first energy signal may be received in the first frequency band based on the received WET request. In one aspect, the first CC may be dedicated to WET across multiple cells, and the one or more CCs associated with WET may include at least one CC configured for WET in a specific cell. On the other hand, the first frequency band dedicated to WET includes multiple subchannels, and the first energy signal may be received in the first subchannel of the multiple subchannels.

[0127] At 916, the UE 902 may obtain an indication of a second CC in the one or more CCs associated with WET within the first CC. Here, the UE 902 may include a power harvesting circuit having a configurable impedance, and the configurable impedance may be configured based on a first frequency band dedicated to WET. At 918, the UE 902 may tune the configurable impedance of the power harvesting circuit based on the second CC.

[0128] At 920, the energy transmitter 903 may transmit a second energy signal in a second frequency CC dedicated to WET from one or more CCs associated with WET. The UE 902 may receive the second energy signal in a second CC dedicated to WET from one or more CCs associated with WET.

[0129] At 922, the UE 902 may indicate that the power density of the first energy signal received in the first subchannel is less than a threshold. The energy transmitter 903 may receive an indication that the power density of the first energy signal received in the first subchannel is less than a threshold.

[0130] At 924, the energy transmitter 903 may transmit a third energy signal in a second subchannel of the plurality of subchannels. Here, the third energy signal in the second subchannel of the plurality of subchannels may be based on receiving an indication that the power density of the first energy signal received in the first subchannel at the UE 902 is less than the threshold at 922. The UE 902 may receive the third energy signal in a second subchannel of the plurality of subchannels. Here, the transmission of the third energy signal in the second subchannel is based on an indication that the power density of the first energy signal received in the first subchannel is less than the threshold at 922.

[0131] At 926, UE 902 may collect RF energy from the first energy signal received at 914 based on receiving the first energy signal in the first frequency band dedicated to WET, or collect RF energy from the second energy signal received at 920 using a power collection circuit based on receiving the second energy signal in the second CC dedicated to WET.

[0132] In one aspect, the power harvesting circuit may have a configurable impedance configured based on a first frequency band dedicated to WET, and in response to UE 902 tuning the configurable impedance of the power harvesting circuit based on the second CC at 918, UE 902 may use the power harvesting circuit having the configurable impedance tuned based on the second CC to collect RF energy from a second energy signal received in the second CC.

[0133] At 927 , the network node 904 may configure at least one WIT band including one or more of a DL WIT band carrying a DL channel, a UL WIT band carrying a UL channel, or a SL WIT band carrying a SL channel for UE 902 to communicate data signals with the network node 904 or another UE 902 .

[0134] At 928, the network node 904 and the UE 902 may communicate the data signal in a RAT frequency band adjacent to the first frequency band in the frequency domain. In one example, the RAT frequency band may not be based on the ACLR caused by the data signal in the WET frequency band. In another example, at least one configuration of the first energy signal sent at 914 may be based on the ACLR caused by the first energy signal in the RAT frequency band.

[0135] The RAT band may be configured to carry a data signal and a mitigation signal configured to reduce ACLR caused by a data signal sent in the RAT band. The UE 902 may communicate a data signal in at least one of a DL channel, a UL channel, or a SL channel, and may communicate at least one of a DL channel, a UL channel, or a SL channel in at least one WIT band including one or more of a DL WIT band carrying a DL channel, a UL WIT band carrying a UL channel, or a SL WIT band carrying a SL channel. In one example, TDD may be performed on at least one WIT band and a first band dedicated to WET. In another example, FDD may be performed on at least one WIT band and a first band dedicated to WET.

[0136] In one aspect, a duplex gap may be configured between a first frequency band and at least one WIT frequency band, and the UE 902 may include a first antenna configured to receive the first frequency band dedicated to WET and a second antenna configured to receive at least a portion of the at least one WIT frequency band.

[0137] On the other hand, the DL WIT band may overlap with the first frequency band in the frequency domain. A guard band may be configured between the first frequency band and the DL WIT band, and a duplex gap may be configured between the first frequency band and the UL WIT band, the duplex gap being larger than the guard band. On the other hand, TDD may be performed on the UL WIT band and the DL WIT band. On the other hand, the first frequency band may include a plurality of subchannels, and the first energy signal may be received in a first subchannel of the plurality of subchannels, and at least one WIT band may overlap with a second subchannel of the plurality of subchannels. A guard band may be configured between the first subchannel and the second subchannel, and TDD may be performed on the UL WIT band and the DL WIT band in the second subchannel.

[0138] Fig.10 1000 is a flowchart of a method for wireless communication. The method may be performed by a UE (e.g., UE 104 / 902; device 1604). According to flowchart 1000, the UE, the energy transmitter, and the network node may be configured to support WET operations. Here, the UE may be an energy receiver including a power collection circuit, and the energy transmitter may be another UE or a network node. In some aspects, a dedicated wireless energy transmission band or subchannel may be configured, and the energy transmitter may be configured to send an energy signal to the UE to connect the UE and communicate with the UE. The network node may configure at least one dedicated WET band / subchannel for the UE and the energy transmitter. The energy transmitter may send an energy signal to the UE on at least one dedicated WET band / subchannel. The UE may use a power collection circuit to collect RF energy from an energy signal received on at least one dedicated WET band / subchannel, and communicate a data signal with the network node.

[0139] At 1006, the UE may send a WET request to at least one network entity for sending a first energy signal in a first frequency band. Here, the at least one network entity may be an energy transmitter or a network node. For example, at 906, the UE 902 may send a WET request to at least one network entity for sending a first energy signal in a first frequency band. In addition, 1006 may be performed by the wireless energy receiving component 198.

[0140] At 1012, the UE may receive a WET instruction for receiving a first energy signal in a first frequency band from a network entity. Here, the network entity may include an energy transmitter or a network node. The first energy signal may be received in the first frequency band at 1014 based on the received WET instruction. The grant or WET instruction may include that at least one configuration of the first energy signal is based on the first frequency band. In one aspect, at least one configuration of the first energy signal may include an EIRP or PSD of the first energy signal. For example, at 912, the UE 902 may receive a WET instruction for receiving a first energy signal in a first frequency band from a network entity. In addition, 1012 may be performed by a wireless energy receiving component 198.

[0141] At 1014, the UE may receive a first energy signal in a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET. The first energy signal may be received in the first frequency band based on the received WET request. In one aspect, the first CC may be dedicated to WET across multiple cells, and the one or more CCs associated with WET may include at least one CC configured for WET in a specific cell. On the other hand, the first frequency band dedicated to WET includes multiple subchannels, and the first energy signal may be received in the first subchannel of the multiple subchannels. For example, at 914, the UE 902 may receive a first energy signal in a first frequency band or a first CC dedicated to WET from one or more frequency bands or one or more CCs associated with WET. In addition, 1014 may be performed by a wireless energy receiving component 198.

[0142] At 1016, the UE may obtain an indication of a second CC in one or more CCs associated with WET within the first CC. Here, the UE may include a power collection circuit with a configurable impedance, and the configurable impedance may be configured based on a first frequency band dedicated to WET. For example, at 916, the UE 902 may obtain an indication of a second CC in one or more CCs associated with WET within the first CC. In addition, 1016 may be performed by the wireless energy receiving component 198.

[0143] At 1018 , the UE may tune the configurable impedance of the power harvesting circuit based on the second CC. For example, at 918 , the UE 902 may tune the configurable impedance of the power harvesting circuit based on the second CC. In addition, 1018 may be performed by the wireless energy receiving component 198 .

[0144] At 1020, the UE may receive a second energy signal in a second CC dedicated to WET from one or more CCs associated with WET.
