In-band deployment for wireless energy and information transfer

Abstract

Methods, systems, and devices for wireless communication are described. Some wireless communication systems can support energy harvesting devices that can harvest power from received radio frequency (RF) signaling. To support energy harvesting, a network entity can configure one or more frequency resources for wireless energy transfer (WET) within a channel bandwidth. The network entity can send a broadcast signal indicating the configuration to a plurality of devices. An energy harvesting device can receive the broadcast signal, identify the frequency resource configured for the WET, and perform energy harvesting using signaling received in the frequency resource. For example, the network entity, user equipment (UE), or any combination of these or other energy providing devices can send signaling in the frequency resource configured for the WET to provide power to an energy harvesting device. In some examples, the network entity can further configure other frequency resources within the channel bandwidth for wireless information transfer (WIT).

Description

Technical Field

[0001] The following relates to wireless communications, including in-band deployments for wireless energy and information transfer. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication of communication devices, which may be referred to as user equipment (UE).

[0003] Some wireless communication systems may support energy harvesting devices. For example, an energy harvesting device may harvest power from radio frequency (RF) signaling received over the air to charge a battery at the energy harvesting device, a power circuit at the energy harvesting device, or both. However, in some cases, the energy harvesting device may not receive enough RF signaling (e.g., a threshold amount of power from the RF signaling) to power the energy harvesting device. In such cases, the battery of the energy harvesting device may decay, or the energy harvesting device may otherwise lose power, potentially resulting in missed communications, dropped connections, lost stored information, or any combination thereof for the energy harvesting device. Summary of the invention

[0004] The described technology relates to improved methods, systems, devices and apparatuses supporting in-band deployment for wireless energy and information transfer. For example, the described technology provides improved resource allocation for wireless energy transfer (WET) within a channel bandwidth. Some wireless communication systems may support energy collection devices that can collect power from received radio frequency (RF) signaling. In order to support effective energy collection, a network entity may configure one or more frequency resources for WET within a channel bandwidth. The network entity may send a broadcast signal indicating the configuration to multiple devices (e.g., energy collection devices, user equipment (UE)). The energy collection device may receive a broadcast signal, identify the frequency resources configured for WET, and perform energy collection using the signaling received in the frequency resources. For example, a network entity, a UE, or any combination of these or other energy providing devices may send signaling in a frequency resource configured for WET to provide power to one or more energy collection devices. Such signaling received in a resource configured for WET may provide sufficient power (e.g., a threshold amount of power from RF signaling) to power the energy collection device. In some examples, the network entity may further configure other frequency resources within the channel bandwidth for wireless information transfer (WIT). For example, the network entity may configure WET signaling to coexist with WIT signaling in the channel bandwidth by mitigating interference caused by WET signaling to WIT signaling, by managing bandwidth transmission for both WET signaling and WIT signaling, or both.

[0051] Some wireless communication systems may include energy harvesting devices. The energy harvesting device may collect power from radio frequency (RF) signaling received in the air to charge a battery at the energy harvesting device, a power circuit at the energy harvesting device, or both. In some systems, the energy harvesting device may collect energy from surrounding RF signals. For example, the energy harvesting device may monitor signals (e.g., on a channel, on a carrier), and may perform energy harvesting operations on the detected signals received by the energy harvesting device. However, such signals may not be intended for energy harvesting use. For example, the surrounding RF signals may include information signals or other RF signals transmitted between devices. Because such signals are not intended for energy harvesting use, these signals may not be optimized or otherwise configured to support efficient energy harvesting procedures. Therefore, relying on surrounding RF signals to power the energy harvesting device may not be enough (e.g., a threshold power level may not be met to power the energy harvesting device). For example, the energy harvesting device may not receive enough power from the surrounding RF signals to charge the battery, the power circuit, or perform one or more other operations.

[0052] In order to support power collection technology, the wireless communication system may be configured with in-band resources for wireless energy transfer (WET). For example, a network entity may configure one or more frequency resources for WET signaling within a channel bandwidth. The network entity may send a broadcast signal indicating the configuration to multiple devices (e.g., a master information block (MIB), a system information block (SIB)). The energy collection device may receive the broadcast signal and identify the frequency resources configured for WET signaling. In some examples, an energy providing device (e.g., a user equipment (UE) or an energy transmitter) may also receive a broadcast signal and identify the frequency resources configured for WET signaling. The network entity or any other energy providing device (e.g., UE, energy transmitter) may send signaling in a frequency resource configured for WET to provide power to one or more energy collection devices. The energy collection device may perform energy collection using signaling received in the frequency resource (e.g., signaling configured for WET). Such signaling configured for WET may provide sufficient power—such as a threshold amount of power from RF signaling—to power the energy collection device. For example, by harvesting energy from resources and signaling configured for WET, an energy harvesting device may charge a battery, power circuits, or perform one or more other operations at the energy harvesting device.

[0053] In some examples, the network entity may additionally configure in-band resources for wireless information transfer (WIT). For example, a wireless device may communicate information in resources configured for WIT. In some cases, an energy harvesting device may use WIT signaling (e.g., received in resources configured for WIT) to perform additional energy harvesting. The network entity may configure WET signaling to coexist with WIT signaling within the channel bandwidth. For example, the network entity may configure a subcarrier spacing (SCS) for a WET signaling waveform to mitigate interference with WIT signaling in the channel. Additionally or alternatively, the network entity may configure one or more guard bands between resources configured for WET and resources configured for WIT to mitigate interference from WET signaling to WIT signaling. In some cases, the network entity may manage transmissions within and outside the channel bandwidth by accounting for transmissions from both WET signaling and WIT signaling.

[0054] Aspects of the present disclosure are first described in the context of a wireless communication system. Additional aspects of the present disclosure are described with respect to in-band resource allocation and process flow. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to in-band deployment for wireless energy and information transfer.

[0055] Figure 1An example of a wireless communication system 100 supporting in-band deployment for wireless energy and information transfer according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, a new radio (NR) network, or a network operating according to other systems and radio technologies (including future systems and radio technologies not explicitly mentioned herein).

[0056] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, etc. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., RF access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0057] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices that take different form factors or have different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as Figure 1 105 or other UEs 115 or network entities 105 shown in FIG.

[0058] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0059] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other on the backhaul links 120 (e.g., according to X2, Xn, or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), and other examples or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0060] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next-generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0061] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0062] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, and RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may both be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 communicating over those communication links.

[0063] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such a case, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0064] Where the techniques described herein are applied to the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support in-band deployment for wireless energy and information transfer as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0065] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.

[0066] like Figure 1 As shown, the UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as repeaters, as well as network entities 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc.

[0067] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) on one or more carriers. The term "carrier" may refer to a set of RF spectrum resources having a defined physical layer structure to support the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0068] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be located based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0069] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0070] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz) of a carrier of a particular radio access technology. A device (e.g., a network entity 105, a UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth or may be configurable to support communication on one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0071] The signal waveform sent on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may refer to a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that the more resource elements a device receives and the higher the order of the modulation scheme, the higher the data rate for the device may be. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0072] One or more numerologies of a carrier may be supported, where the numerologies may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP of a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0073] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0074] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro time slots including one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0075] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0076] Physical channels may be multiplexed on a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed on a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of the control channel candidates may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coding information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0077] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0078] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power network entity 105 (e.g., a lower power base station 140) (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with a small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells, and may also use one or more component carriers to support communications on one or more cells.

[0079] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0080] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0081] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may allow automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0082] Some UEs 115 may be configured to employ a mode of operation that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power conservation techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0083] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency may be used interchangeably herein.

[0084] In some examples, UE 115 may be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communications may be within a coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communications configured or scheduled by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, multiple groups of UEs 115 communicating via D2D communications may support a one-to-many (1:M) system in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, the network entity 105 may facilitate scheduling resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105 .

[0085] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW)), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. The IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0086] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range length is about one decimeter to one meter. The UHF waves may be blocked or redirected by buildings and environmental features, and these waves may be referred to as clusters, but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmission using smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0087] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ licensed assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a carrier aggregation configuration (e.g., LAA) combined with component carriers operating in licensed bands. Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0088] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may have an antenna array having a set of rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0089] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0090] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reorganization to communicate on the logical channel. The MAC layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer that supports user plane data between the UE 115 and the network entity 105 or the core network 130. At the PHY layer, the transport channel can be mapped to the physical channel.

[0091] UE 115 and network entity 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data through a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0092] The wireless communication system 100 may include devices (e.g., UE 115, network entity 105) that support energy harvesting techniques. For example, UE 115, which may be an example of an energy harvesting device, may use energy from RF signaling, solar energy, vibration energy, or any combination thereof to charge a battery or another power circuit at UE 115. Examples of energy harvesting devices may include radio frequency identification (RFID) tags, passive IoT devices, and UE 115 (e.g., relatively low power or low complexity UE 115), as well as other energy harvesting devices. As described herein, an energy harvesting device may receive a signal and may use the RF energy of the signal to harvest energy (e.g., to power one or more operations at the energy harvesting device).

[0093] For example, the wireless communication system 100 may support RFID technology. Some example systems (e.g., RFID systems) using RFID technology may include inventory management, asset management, or both for warehouses (e.g., inside a warehouse, outside a warehouse), IoT systems, sustainable sensor networks (e.g., in a factory, in an agricultural system), smart homes, or any combination of these or other systems including RFID devices. RFID systems may include relatively small transponders (e.g., microchips), which may be referred to as RFID tags, which transmit information-bearing signals in response to received signals. RFID tags may work with relatively low operating expenses (OPEX), relatively low maintenance costs, and long life cycles without batteries based on the use of energy harvesting techniques. Alternatively, RFID tags may work as semi-passive or active RFID devices with batteries (e.g., at relatively high costs), and energy harvesting techniques may be used to support charging the batteries. For example, RFID tags (e.g., passive, semi-passive, or active RFID devices) may collect energy in the air to power circuits (e.g., transmit / receive circuits) at RFID tags. The RFID tag may receive the first signal in the air, collect energy from the signal, and transmit a second signal in response to the received signal, which second signal may be an example of a backscatter modulated information signal. In some examples, the first signal may be transmitted by an RFID reader, the second signal may be received at the RFID reader, or both.

[0094] Additionally or alternatively, the wireless communication system 100 may support passive IoT technology. For example, URLLC systems, MTC systems or other systems (e.g., 5G systems, 6G systems and later systems) may support passive IoT technology. In some examples, the wireless communication system 100 may support MTC devices, NB-IoT devices, reduced capability (RedCap) devices, or some combination thereof for MTC operations, wherein such devices may work using energy harvesting technology. Additionally or alternatively, the wireless communication system 100 may support RFID-type sensors (e.g., passive IoT devices) for asset management, logistics, warehousing, manufacturing, or any other use case. The popularity of such passive IoT devices in some wireless communication systems 100 may affect energy usage within the wireless communication system 100. For example, in order to support passive IoT devices throughout the system, passive IoT devices may collect energy from signaling (e.g., surrounding RF signaling, dedicated RF signaling) to efficiently maintain power at the passive IoT device.

[0095] In some cases, the network (e.g., via a network entity 105 such as a base station 140 or RU 170) may manage passive IoT devices (e.g., one or more UEs 115). For example, the network entity 105 may read information from the passive IoT device, write information to the passive IoT device, or both. The network entity 105 may also provide energy to the passive IoT device (e.g., using over-the-air RF signaling). Additionally or alternatively, some UEs 115 (e.g., energy providing devices) may provide energy to other UEs 115 (e.g., energy harvesting devices, such as passive IoT devices). In some examples, the passive IoT device may reflect an information-bearing signal to the network entity 105 (e.g., as part of, as a result of, or as a substitute for an energy harvesting operation at the passive IoT device). The network entity 105 may receive the reflected signal from the passive IoT device and decode the information in the reflected signal (e.g., sent by the passive IoT device).

[0096] An energy harvesting device (e.g., an RFID tag, a passive IoT device, a UE 115) may include a power harvesting circuit. For example, due to diodes in the circuit, power harvesting may be nonlinear with respect to input power at the power harvesting circuit. For example, an energy harvesting device may receive a signal at an antenna and may transmit the signal for impedance matching. After impedance matching, the signal may be transmitted to a power harvesting circuit (e.g., for energy harvesting), a demodulator (e.g., for demodulation if the signal includes information for an energy harvesting device), or both. In some cases, the power harvesting circuit may include a threshold input power (e.g., for a received signal) at which the circuit turns on and performs a power harvesting operation on the signal. The threshold input power may be based on the turn-on voltage of one or more diodes in the power harvesting circuit. For example, the threshold input power may be -20 decibel-milliwatts (dBm), -10 dBm, or some other value for triggering activation of the power harvesting circuit. If the input power of the received signal (e.g., at reception, after impedance matching) meets the threshold input power (e.g., is greater than or equal to the threshold input power), the received signal may be processed by the power harvesting circuit to harvest energy from the signal. In some cases, the power harvesting circuit may be relatively more efficient at lower frequencies due to diode junction capacitance and resistance (e.g., based on frequency selective conversion efficiency). The power harvesting circuit may transfer the resulting harvested energy to a voltage regulator, a boost converter, or both. The voltage regulator may provide energy (e.g., based on energy received from the power harvesting circuit) to one or more microcontroller units (MCUs), one or more sensors, or both to power such components. The boost converter may transfer energy (e.g., based on energy received from the power harvesting circuit) to an energy reservoir or other energy storage mechanism (e.g., a battery) for later use.

[0097] In some systems, an energy harvesting device may harvest energy from ambient RF signals. For example, the energy harvesting device may monitor signals (e.g., on a channel, on a carrier), and may perform energy harvesting operations on detected signals received by the energy harvesting device. Such signals may not be intended for energy harvesting use; that is, the energy harvesting device may perform energy harvesting on information signals or other RF signals that are transmitted between different devices, transmitted to the energy harvesting device, or both. Because such signals (e.g., digital television (DTV) signals, global system for mobile communications (GSM) signals, 3G signals, Wi-Fi signals, or other ambient RF signals) are not dedicated to energy harvesting, these signals may not be optimized or otherwise configured to support efficient energy harvesting. For example, the power density of the ambient RF signal may be lower than a threshold density (e.g., 10 nanowatts per square centimeter (nW / cm2)) that supports effective charging for the energy harvesting device. 2 )). Additionally or alternatively, the power level of the ambient RF signal may vary over time, by location, or both. Therefore, relying on the ambient RF signal to power the energy harvesting device may be insufficient. For example, the energy harvesting device may not receive enough power from the ambient RF signal to charge a battery, power circuit, perform one or more operations, or any combination thereof.

[0098] To support energy harvesting devices (e.g., RFID tags, passive IoT devices, UE 115), the wireless communication system 100 may use dedicated energy sources, dedicated energy harvesting signals, or both. For example, a first signal type may be dedicated to WIT. Such signaling may carry information between devices in the wireless communication system 100 (e.g., between UE 115, network entity 105, or some combination thereof). In some cases, signaling dedicated to WIT (e.g., NR signaling) may be additionally used for energy harvesting (e.g., ambient energy harvesting). The second signal type may be dedicated to WET. Such signaling may refrain from carrying information between devices in the wireless communication system 100 and may instead include RF energy to be used for energy harvesting. Therefore, the second signal type may be configured to optimize—or otherwise improve—the efficiency of harvesting energy from the second signal type.

[0099] Frequency bands may be reserved for WET, WIT, or a combination of WET and WIT. For example, a network (e.g., via network entity 105) may be configured for WET signaling, WIT signaling, or a frequency band for both. In some cases, a network may be configured for a frequency band dedicated to WET. Such a dedicated frequency band may provide energy coverage for multiple energy harvesting devices (e.g., ubiquitous uninterrupted wireless power IoT devices) in the wireless communication system 100. By using dedicated WET signaling, the wireless communication system 100 may improve the effective power density for energy harvesting, thereby allowing the energy harvesting device (e.g., from RF signaling) to receive enough power to charge a battery, a power circuit, perform one or more operations, or any combination thereof. Specifically, the in-band deployment of WET (e.g., together with WIT) may support improved energy harvesting of energy harvesting devices, thereby reducing the possibility of energy harvesting devices losing power, improving communication with energy harvesting devices, and improving the reliability of energy harvesting devices.

[0100] Figure 2 An example of a wireless communication system 200 supporting in-band deployment for wireless energy and information transfer according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may support aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a network entity 105-a, a UE 115-a, and an energy harvesting device 205, which may be related to Figure 1 An example of a corresponding device described. The energy harvesting device 205 can be an example of a UE 115, a network entity 105, or any other device using energy harvesting technology (e.g., an RFID tag, a passive IoT device). The network entity 105-a, the UE 115-a, or both can use dedicated WET signaling 230 to provide energy to the energy harvesting device 205. Additionally, the network entity 105-a, the UE 115-a, the energy harvesting device 205, or any combination thereof can use WIT signaling 235 to convey information. The wireless communication system 200 can support in-band deployment of both WET signaling 230 and WIT signaling 235 to support efficient resource usage of channel bandwidth.

[0101] The network entity 105-a may reserve one or more frequency resources (e.g., RBs) within the channel bandwidth for WET signaling 230. In some examples, the reserved frequency resources may be cell-specific. For example, the network entity 105-a may configure frequency resources for WET signaling 230 for a specific cell (e.g., in one or more BWPs). In some cases, the network entity 105-a may send broadcast signaling 225 indicating the configuration of frequency resources for WET signaling 230. For example, the network entity 105-a may broadcast the configuration (e.g., in the MIB, in the SIB) to multiple devices such as the energy collection device 205 via the downlink channel 210-a, and broadcast the configuration to the UE 115-a via the downlink channel 210-b. Additionally or alternatively, the network entity 105-a may configure the frequency resources for WET signaling 235. The network entity 105-a may broadcast an indication (e.g., configuration) of the WIT resources to the energy harvesting device 205, the UE 115-a, or both in the MIB, the SIB, or both. For example, the network entity 105-a may broadcast the WET resources and the configuration of the WIT resources for the channel bandwidth to multiple devices in the wireless communication system 200.

[0102] Devices residing on the cell (e.g., energy collection devices 205 and UE 115-a connected to the network via a network entity 105-a serving the cell) can identify frequency resources configured for WET signaling 230 based on broadcast signaling 225. The energy collection device 205 can tune the power collection circuit to the frequency resources in the band, can activate the power collection circuit for WET signaling 230, or both to support efficient power collection for specific frequency resources. Therefore, the energy collection device 205 can collect energy from a licensed spectrum (e.g., a portion of a licensed spectrum configured for WET and WIT). The licensed spectrum can support relatively more controllable interference than other spectrums (e.g., UHF spectrum). Additionally or alternatively, the licensed spectrum can support relatively higher transmission power for WET signaling 230 than other spectrums (e.g., UHF spectrum). In order to support efficient deployment, a software update at the network entity 105-a can allow the network entity 105-a to configure in-band resources for WET signaling 230.

[0103] The energy collection device 205 may receive the broadcast signaling 225-a and may determine one or more frequency resources for monitoring energy collection. In some examples, the energy collection device 205 may collect energy from WET signaling 230 (e.g., based on a configuration performed by the network) sent in a frequency resource dedicated to WET. In some cases, the network entity 105-a may send WET signaling 230-a in one or more frequency resources dedicated to WET on the downlink channel 210-a. That is, the network entity 105-a may send a configuration to the energy collection device 205, and may also send WET signaling 230-a to the energy collection device 205 in a resource dedicated to WET signaling 230 in the configuration.

[0104] Additionally or alternatively, the UE 115-a may send WET signaling 230-b on the sidelink channel 220-a in one or more frequency resources dedicated to WET. For example, the UE 115-a may receive a configuration from the network entity 105-a (e.g., in broadcast signaling 225-a) and may determine whether to send the WET signaling 230 in the frequency resources allocated for the WET signaling 230. In some examples, the UE 115-a may determine whether to send the WET signaling 230 based on a communication schedule for the UE 115-a (e.g., if the UE 115-a is not scheduled for other transmission or reception in the frequency resources), an available power at the UE 115-a (e.g., if the available power at the UE 115-a satisfies a power threshold), or one or more other parameters or decision metrics.

[0105] Additionally or alternatively, the energy transmitter may send WET signaling 230 in the frequency resources allocated for WET signaling 230. The energy transmitter may be an example of a device configured to perform WET for energy harvesting purposes. The energy transmitter may be deployed in the wireless communication system 200 to support WET. The energy transmitter may (e.g., based on a configuration from broadcast signaling or based on a configuration of the energy transmitter) identify the frequency resources allocated for WET signaling 230, and may access the allocated frequency resources to supply power to one or more energy harvesting devices 205.

[0106] The energy collection device 205 may receive WET signaling 230 (e.g., from a network entity 105-a, a UE 115-a, an energy transmitter, or some combination of these devices or other devices configured for WET), and may use a power collection circuit at the energy collection device 205 to collect power from the WET signaling 230. Additionally or alternatively, the energy collection device 205 may collect energy from other transmissions (e.g., RF signaling) in the wireless communication system 200. For example, the energy collection device 205 may collect energy from WIT signaling 235 (e.g., an RF signal used to convey information between wireless devices). In some examples, the energy collection device 205 may collect energy from WIT signaling 235 without using WIT signaling 235 for information communication. For example, the energy collection device 205 may refrain from demodulating the WIT signaling 235, refrain from decoding the WIT signaling 235, or both. For example, the UE 115-a and the network entity 105-a may communicate information to each other using WIT signaling 235. The energy harvesting device 205 may detect the WIT signaling 235 (eg, between the UE 115-a and the network entity 105-a) and may harvest energy from the WIT signaling 235.

[0107] In some other examples, the energy harvesting device 205 may receive WIT signaling 235 and decode the WIT signaling 235 to obtain information in addition to collecting energy from the WIT signaling 235. The WIT signaling 235 may be sent by the network in resources (e.g., frequency resources) configured for the WIT signaling 235. For example, the channel bandwidth may be configured to include a first subset of frequency resources configured for WIT signaling 230, a second subset of frequency resources configured for WIT signaling 235, and—in some cases—a third subset of frequency resources configured to support WET signaling 230, WIT signaling 235, or a combination of both. The network entity 105-a may send the WIT signaling 235-a to the energy harvesting device 205 on the downlink channel 210-a. Additionally or alternatively, the UE 115-a may send the WIT signaling 235-c to the energy harvesting device 205 on the sidelink channel 220-a. The energy harvesting device 205 may determine information from the WIT signaling 235, harvest energy from the WIT signaling 235, or both.

[0108] Additionally or alternatively, the energy collection device 205 may use resources configured for WIT signaling 235 for transmission. For example, the energy collection device 205 may send WIT signaling 235-b to the network entity 105-a on the uplink channel 215. In some cases, the energy collection device 205 may send WIT signaling 235-d to the UE 115-a on the sidelink channel 220-b. In some cases, the energy collection device 205 may send WIT signaling 235 to request WET signaling 230 (e.g., from a specific device such as the network entity 105-a or UE 115-a or from any device that receives the WIT signaling 235 and is capable of providing energy). In some other cases, the energy collection device 205 may send other information (e.g., confirmation signaling, backscatter modulation information signaling, sensor data). Thus, wireless devices in the wireless communication system 200 may communicate information within the same band (eg, same frequency band, same BWP, same channel bandwidth, same carrier bandwidth) and send signaling dedicated to energy harvesting.

[0109] In some examples, WET signaling 230 and WIT signaling 235 may occupy the same resource. For example, one or more devices may use the same resource to send an information signal and an energy signal. In some other examples, WET signaling 230 and WIT signaling 235 may occupy different resources. For example, the network entity 105-a may configure one or more WIT BWPs and one or more WET bands (e.g., WET BWPs). Resources configured for WIT may be reserved for downlink transmissions, uplink transmissions, or both (e.g., in the time domain, in the frequency domain, in the spatial domain). In some cases, WIT resources may occupy different subcarriers, different subchannels, or both in different RBs. For example, the network entity 105-a may select a downlink subcarrier for WIT signaling 235 so that the downlink subcarriers are separated by a value Δf in frequency. DL . Value Δf DL may be selected so that multipath destructive interference can be resolved when the device hops between subcarriers. For example, if the first downlink subcarrier configured for WIT signaling 235 is at frequency f1, destructive multipath interference may occur if the first path and the second path differ by 0.5×c / f1. Therefore, the network may select a second downlink subcarrier to be configured for WIT signaling 235 at frequency f2 such that f2=f1+Δf DL, where 0.5×f2 / f1≠0.5. The network may select uplink subcarriers for WIT signaling 235 based on one or more downlink subcarriers for WIT signaling 235 to support backscattering with subcarrier modulation. For example, the network may apply a relatively small frequency shift to the downlink subcarriers for WIT signaling 235 to determine the uplink subcarriers for WIT signaling 235. In some cases, to reduce hardware complexity, the network may select uplink subcarriers for WIT signaling 235 such that the additional frequency separated from the downlink subcarriers for WIT signaling 235 satisfies Δf 分开 =f1 / N, where N can be selected as an integer or a power of 2 (e.g., 8, 16, 32, 64, 128).

[0110] Figure 3 An example of in-band resource allocation 300 for supporting in-band deployment for wireless energy and information transfer according to one or more aspects of the present disclosure is illustrated. In-band resource allocation 300 may be used in wireless communication system 100, wireless communication system 200, or both. For example, network entity 105 (such as reference Figure 1 and Figure 2 The network entity 105 (eg, base station 140 or other network device) described herein may configure in-band resource allocation 300 to support WET and WIT. UE 115 (eg, a base station 140 or other network device) described herein may configure in-band resource allocation 300 to support WET and WIT. Figure 1 and Figure 2 10. The UE 115 described herein may identify the in-band resource allocation 300 (e.g., by receiving an indication of the configuration from the network entity 105) and determine the resources 315 allocated for WIT, the resources 320 allocated for WET, or both. In some cases, the UE 115 may be an example of an energy providing device and may identify the resources 320 allocated for WET so as to send WET signaling in the resources 320 allocated for WET. In some other cases, the UE 115 may be an example of an energy harvesting device and may identify the resources 320 allocated for WET so as to receive WET signaling in the resources 320 allocated for WET to perform energy harvesting.

[0111] The in-band resource allocation 300 may support in-band deployment of WET (e.g., resources 320 allocated for WET). The in-band resource allocation 300 may configure frequency resources dedicated to WIT signaling, frequency resources dedicated to WET signaling, or a combination thereof. The network (e.g., the network entity 105) may determine (e.g., configure) the in-band resource allocation 300 for a channel bandwidth (e.g., a specific frequency band, a specific BWP). In some cases, the in-band resource allocation 300 may correspond to a specific cell.

[0112] As illustrated, resources 320 allocated for WET and resources 315 allocated for WIT may be frequency division duplexed (FDDed) within a channel bandwidth 305 (e.g., an NR channel bandwidth or other channel bandwidth). The channel bandwidth 305 may be organized according to frequency resources such as RBs 310, subcarriers, or other frequency units. The frequency resources of the channel bandwidth 305 may be configured for WET signaling, WIT signaling, both (e.g., concurrently or at different times according to a time division duplex (TDD) framework), or neither (e.g., gaps in the frequency domain). For example, the network (e.g., via the network entity 105) may configure one or more resources 320 allocated for WET and one or more resources 315 allocated for WIT within the channel bandwidth 305 (e.g., in-band).

[0113] In some cases, the WET subcarrier or subchannel, the WIT subcarrier or subchannel, or both may be smaller than one RB 310. Additionally or alternatively, the network (e.g., via the network entity 105) may configure the WIT resources to avoid synchronization signal block (SSB) resources, physical random access channel (PRACH) resources, or both. In some examples, the UE 115 may avoid or puncture transmissions on the WIT subcarrier or subchannel.

[0114] An energy harvesting device (e.g., UE 115 or other device) operating on a channel bandwidth 305, operating on a cell specific to an in-band resource allocation 300, or both may harvest energy from resources 320 allocated for WET. For example, an energy harvesting device may monitor resources 320 allocated for WET for WET signaling, and may transmit signaling received on resources 320 allocated for WET to a power harvesting circuit for energy harvesting. Additionally or alternatively, an energy harvesting device may harvest energy from resources 315 allocated for WIT. For example, an energy harvesting device may harvest energy from an RB 310 (e.g., based on SSB) adjacent to an RB 310 configured for WET signaling, or may harvest energy from any other RB 310 in the channel bandwidth 305. However, signaling received on resources 315 allocated for WIT may not be optimized for energy harvesting as signaling received on resources 320 allocated for WET. Specifically, the WET signal may be configured or otherwise designed to improve energy harvesting at the energy harvesting device.

[0115] For example, WET signaling (e.g., signaling sent in resources 320 allocated for WET) can be sent using a dedicated waveform for energy collection. In some examples, the WET signaling waveform can support energy with potential power boost. For example, a device (e.g., network entity 105, UE 115) can support a first transmit power 325-a as an average power for a carrier (e.g., an average value for WET signaling and WIT signaling in a channel bandwidth 305). The device can increase the transmit power 325-b used for WET signaling to above the first transmit power 325-a (e.g., average transmit power) to increase the power available for energy collection in resources 320 allocated for WET. In some cases, a power boost amount 330 (e.g., defined as the ratio of the transmit power for WET to the average transmit power for WET and WIT) can be configured as a set value (e.g., +6 decibels (dB), +9dB) to ensure coverage of energy delivery. In some examples, the power boost can be based on the configuration of the transmitting device. For example, the network entity 105 (e.g., the base station 140) may perform FDM WET and WIT transmissions using a transmit power that satisfies a rated output power threshold, power dynamics, or both for a particular class of network entities 105. In some cases, the network may configure multiple WET bands in-band (e.g., a collection of resources 320 that are consecutively allocated for WET). In some such cases, the network entity 105—or the UE 115—may support power boosting for one of the multiple WET bands at a time in the channel bandwidth 305.

[0116] The waveform used for in-band WET signaling may adopt an OFDM waveform with a specific SCS. For example, the SCS used for the OFDM waveform may support WET signaling on the downlink to be orthogonal to WIT signaling (e.g., NR signaling) on ​​the downlink (e.g., continuous with WET signaling within the channel bandwidth 305 or in the frequency domain).

[0117] As an example, the resources 320 allocated for WET may be contiguous with the first BWP 335-a, the second BWP 335-b, or both. The first BWP 335-a, the second BWP 335-b, or both may be configured for WIT signaling (e.g., NR signaling or other signaling). In some cases, the first BWP 335-a and the second BWP 335-b may use the same SCS. For example, the first BWP 335-a and the second BWP 335-b may be the same BWP or may be different BWPs configured according to the same SCS. In some such cases, WET signaling (e.g., OFDM waveforms for WET signaling) may use the same SCS as the adjacent BWP to support signaling in adjacent BWPs (e.g., the first BWP 335-a and the second BWP 335-b)) orthogonal to WET signaling in the resources 320 allocated for WET. The in-band resource allocation 300 may use the same SCS as the waveform used for WET signaling and be orthogonal to the waveform used for WIT signaling without including guard subcarriers (e.g., guard bands) between the resources 320 allocated for WET and the resources 315 allocated for WIT (e.g., in the first BWP 335-a, in the second BWP 335-b).

[0118] In some cases, the network may refrain from configuring resources allocated for WET between BWPs with different BWP parameter sets (e.g., different SCSs) 320. That is, the network may deploy WET in-band according to a set of rules so that the WET resources use the same SCS as the WIT resources adjacent to the WET resources in the frequency domain.

[0119] In some other cases, the first BWP 335-a and the second BWP 335-b may use different SCSs. For example, the first BWP 335-a may be configured with a first BWP parameter set corresponding to a first SCS for WIT signaling and the second BWP 335-b may be configured with a second BWP parameter set corresponding to a second SCS for WIT signaling. In a first example, WET signaling (e.g., an OFDM waveform used for WET signaling) may use the same SCS as one of the BWPs, for example, according to a rule (e.g., WET signaling uses a smaller SCS, WET signaling uses a larger SCS). Therefore, WET signaling may be orthogonal to WIT signaling in one BWP of the BWP but not in another BWP. The network may apply a guard subcarrier (e.g., a guard band) between the resources 320 allocated for WET and the resources 315 allocated for WIT of a BWP that is not orthogonal to WET signaling. For example, if WET signaling is configured according to the first SCS, the network may apply a guard band between the resources 320 allocated for WET and the second BWP 335-b. The guard band may mitigate interference (e.g., inter-parameter set interference) between WET signaling and WIT signaling in the second BWP 335-b that is non-orthogonal to the WET signaling.

[0120] In a second example, WET signaling (e.g., an OFDM waveform used for WET signaling) may use a third SCS that is different from the first SCS used for the first BWP 335-a and different from the second SCS used for the second BWP 335-b. Thus, WET signaling may be non-orthogonal to WIT signaling in both the first BWP 335-a and the second BWP 335-b. The network may apply a guard band between the first BWP 335-a and the resources 320 allocated for WET and between the second BWP 335-b and the resources 320 allocated for WET to mitigate interference (e.g., inter-parameter set interference) between WET signaling and WIT signaling using different SCSs.

[0121] In a third example, WET signaling (e.g., an OFDM waveform used for WET signaling) may use multiple SCSs. For example, different parts of the WET signaling may use different SCSs. In some cases, a first group of frequency resources in the resources 320 allocated for WET adjacent to the first BWP 335-a may use a first SCS (e.g., the same SCS as the first BWP 335-a). Similarly, a second group of frequency resources in the resources 320 allocated for WET adjacent to the second BWP 335-b may use a second SCS (e.g., the same SCS as the second BWP 335-b). In some examples, a third group of frequency resources between the first group of frequency resources and the second group of frequency resources in the resources 320 allocated for WET may use a third SCS (e.g., an SCS value between the first SCS value and the second SCS value). A device (e.g., network entity 105) that sends WET signaling may apply reduced transmit power to WET signaling in the third set of frequency resources to reduce interference to the first BWP 335-a, the second BWP 335-b, or both. In some cases, the device may reduce the transmit power in the third set of frequency resources to zero. Interference (e.g., inter-parameter set interference) within the resources 320 allocated for WET may not affect WET signaling because WET signaling is used to carry energy for energy harvesting and not for information transfer. However, the techniques described herein can effectively reduce or mitigate interference from WET signaling to WIT signaling in adjacent or nearby BWPs.

[0122] Additionally or alternatively, in-band resource allocation 300 may manage transmissions from WET signaling. WET transmissions into adjacent BWPs (e.g., BWPs directly bordering resources 320 allocated for WET or BWPs separated from resources 320 allocated for WET by a guard band) may be defined by spectral emission masking, total in-band emission (IBE), or both. The network may configure WET signaling so that energy emissions outside resources 320 allocated for WET may meet a threshold (e.g., not exceed a threshold) and may be attenuated for frequencies farther from resources 320 allocated for WET (e.g., according to one or more additional emission thresholds). Because interference may not negatively affect WET signaling, the network may relax the IBE threshold into resources 320 allocated for WET (e.g., WIT signaling may be allowed to have larger transmissions into resources 320 allocated for WET). However, the network may apply the IBE threshold outside resources 320 allocated for WET and into resources 315 allocated for WIT. Additionally or alternatively, the network may ensure that the total transmission of WET signaling and WIT signaling from outside the carrier (e.g., channel bandwidth 305) satisfies an out-of-band (OOB) threshold, an adjacent channel leakage ratio (ACLR) threshold, or both. Additionally or alternatively, in a paired spectrum, the transmission threshold may be different for different channels, different devices, or both. For example, UE 115 and network entity 105 may apply different transmission thresholds. Additionally or alternatively, a device may apply different transmission thresholds for an uplink channel, a downlink channel, a sidelink channel, or some combination thereof. In an unpaired spectrum, in some cases, multiple devices (e.g., network entity 105 and UE 115) may concurrently access resources 320 allocated for WET.

[0123] For example, based on the configuration of the device in the channel, resource, network or any combination thereof, the resource 320 allocated for WET can be used for different processes. In some examples, the network entity 105, UE 115 or both can send a dedicated energy signal (e.g., optimized for WET or otherwise configured) in the resource 320 allocated for WET. For example, the dedicated energy signal can be a multi-sine signal. In some examples, the UE 115 can be scheduled by a dedicated energy signal (e.g., in a paired or unpaired spectrum) from the network entity 105. In some cases, the resource 320 allocated for WET can be configured for general WET or for device-specific WET. For example, for general WET, the device sending WET signaling can broadcast WET signaling, send WET signaling in multiple directions (e.g., using beam scanning) or send WET signaling in pseudo-random directions. For device-specific WET, different parts of the resource 320 allocated for WET can be allocated for WET to a specific energy collection device. For example, a first subset of frequency resources in the resources 320 allocated for WET may be allocated for energy transfer to a first energy harvesting device, and a second subset of frequency resources in the resources 320 allocated for WET may be allocated for energy transfer to a second energy harvesting device. Thus, WET signaling may be sent in different subsets of frequency resources in a particular direction to support energy harvesting at a particular device. Additionally or alternatively, WET signaling for different energy harvesting devices may be time division duplexed (TDDed) in the resources 320 allocated for WET.

[0124] In some examples, the WET signaling in the resources 320 allocated for WET may also include information. For example, the WET signaling may include NR signaling (e.g., using an NR waveform), NB-IoT signaling, or other signaling that carries information. The network entity 105, the UE 115, or both may use the WET signaling for communication—potentially at a relatively high transmit power—while the energy harvesting device may harvest power from the WET signaling.

[0125] In some examples, WET signaling may support the transmission of repeated information signals (e.g., NR or NB-IoT signals). Devices (e.g., UE 115, network entity 105) may opportunistically receive WET signaling to recover missed messages, improve communication reliability, improve decoding success rate, or any combination thereof. Additionally, energy harvesting devices may use WET signaling for energy harvesting. In some cases, repeated transmissions in resources 320 allocated for WET may include physical uplink shared channel (PUSCH) transmissions, physical uplink control channel (PUCCH) transmissions, physical downlink shared channel (PDSCH) transmissions, physical downlink control channel (PDCCH) transmissions, physical sidelink shared channel (PSSCH) transmissions, physical sidelink control channel (PSCCH) transmissions, or any other repeated transmissions. In some examples, a device that transmits repeated transmissions may modify one or more transmission parameters (e.g., transmit power) when opportunistically transmitting repeated transmissions in resources 320 allocated for WET. Additionally or alternatively, the repeated transmissions may be examples of reference signals used to support improved channel estimation, phase noise cancellation, or both. For example, the device may transmit SSB, a channel state information reference signal (CSI-RS), or another reference signal in resources 320 allocated for WET for reference signal measurement and energy collection.

[0126] In some examples, WET signaling may support a signal shaping signal. For example, the network entity 105 may send a signal shaping signal in the resources 320 allocated for WET on the downlink. Additionally or alternatively, the UE 115 may send a signal shaping signal in the resources 320 allocated for WET on the uplink. For example, the resources 320 allocated for WET may be used for tone reservation (TR) for peak-to-average power ratio (PAPR) reduction, for active interference cancellation (AIC) for emission reduction, or both.

[0127] Figure 4 An example of a process flow 400 for supporting in-band deployment for wireless energy and information transfer in accordance with one or more aspects of the present disclosure is illustrated. The process flow 400 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, or both. The process flow 400 may include a UE 115-b, a network entity 105-b, and an energy harvesting device 405 (e.g., an RFID tag, a passive IoT device, another UE 115), which may be as described herein with reference to Figures 1 to 3 For example, the UE 115-b, the network entity 105-b, and the energy harvesting device 405 may be configured based on in-band deployment of WET signaling and WIT signaling (e.g., based on in-band resource allocation, such as described in reference Figure 3 In the following description of process flow 400, the operations performed by the device may be performed in a different order or at a different time. Additionally or alternatively, some operations may be omitted from process flow 400 and other operations may be added to process flow 400.

[0128] At 410, the network entity 105-b may allocate frequency resources for WET, WIT, or both. For example, the network entity 105-b may allocate one or more frequency resources within a channel bandwidth (e.g., in a licensed spectrum) in a cellular network for WET. Additionally, the network entity 105-b may allocate one or more additional frequency resources for WIT (e.g., on an uplink channel, a downlink channel, a sidelink channel, or some combination thereof).

[0129] At 415, the network entity 105-b may send a broadcast signal indicating resource allocation (e.g., resource configuration). For example, the network entity 105-b may broadcast signaling indicating one or more frequency resources configured for WET, one or more additional frequency resources configured for WIT, or both. In some cases, the broadcast signal may be an example of a MIB or a SIB. Additionally or alternatively, the network entity 105-b may send other configuration information for resource allocation in control signaling such as a MIB, a SIB, a MAC control element (CE), a downlink control information (DCI), or any combination thereof. The broadcast signal may include a bitmap or an index to a bitmap identifying at least one or more frequency resources configured for WET. Alternatively, the broadcast signal may indicate a corresponding set of one or more frequency resources configured for WET within a corresponding BWP.

[0130] The energy collection device 405 may receive a broadcast signal and determine resource allocation. For example, the energy collection device 405 may receive a broadcast signal indicating one or more frequency resources allocated for WET within a channel bandwidth. Additionally or alternatively, UE 115-b (e.g., an energy providing device) may receive a broadcast signal and determine resource allocation. In some examples, resources allocated for WET may be allocated for a specific energy collection device. For example, a subset of one or more frequency resources allocated for WET may be allocated for WET specifically to the energy collection device 405 (e.g., a collection of multiple energy collection devices from a wireless communication system).

[0131] In some examples, UE 115-b may provide energy to energy harvesting device 405 (e.g., using RF signaling) for energy harvesting. In some cases, at 420, UE 115-b may perform power boosting. For example, UE 115-b may power boost a signal for WET based on a power boost threshold. At 425, UE 115-b may send a signal for WET in one or more frequency resources allocated for WET (e.g., based on the broadcast signal received at 415).

[0132] Additionally or alternatively, the network entity 105-b may provide energy to the energy harvesting device 405 (e.g., using RF signaling) for energy harvesting. In some cases, at 430, the network entity 105-b may power boost the signal for WET based on the power boost threshold. At 435, the network entity 105-b may send the signal for WET to the energy harvesting device 405 in one or more frequency resources allocated for WET (e.g., based on configuration by the network entity 105-b).

[0133] The signal used for WET (e.g., from UE 115-b or from network entity 105-b) can be an example of a signal dedicated to energy transfer or can be an example of PUCCH signaling, PUSCH signaling, sidelink signaling, signal shaping signaling, PDCCH signaling, PDSCH signaling, or any combination thereof.

[0134] At 440, the energy harvesting device 405 may perform energy harvesting. For example, the energy harvesting device 405 may receive a signal within one or more frequency resources allocated for WET. The signal may be usable for performing WET according to the broadcast signal received at 415. The energy harvesting device 405 may receive signaling for WET from the UE 115-b (e.g., at 425), from the network entity 105-b (e.g., at 435), or both. The energy harvesting device 405 may perform energy harvesting using the signal received within one or more frequency resources allocated for WET.

[0135] In some cases, the energy collection device 405 may use one or more additional signals (e.g., where the one or more additional signals may be WIT signaling) received outside of one or more frequency resources allocated for WET to additionally perform energy collection. For example, at 445, the device may communicate using WIT signaling. For example, the network entity 105-b may communicate with the energy collection device 405, the UE 115-b, or both. Additionally or alternatively, the energy collection device 405 may communicate with the UE 115-b. At 450, in some cases, the energy collection device 405 may perform additional energy collection using WIT signaling detected by the energy collection device 405.
