[0002] This patent application claims the benefit of Greek patent application No. 20220100609, entitled “TIME-DOMAINBEHAVIOR AND ENERGYREQUESTINDICATIONS FOR ENERGY HARVESTING DEVICES,” filed by ELSHAFIE et al. on July 27, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications, including the time domain behavior of energy harvesting (EH) devices and energy request indications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, 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 communications for communication devices, which may be referred to as user equipment (UE). Summary of the invention

[0005] The described technology relates to improved methods, systems, devices and apparatuses for supporting time domain behavior and energy request indication of energy harvesting (EH) devices (which may also be or be referred to as energy receiver devices herein). For example, the described technology allows a network to prioritize charging a set of EH UEs using a collection of energy transmitter (ET) user equipment (UE) (which may also be or be referred to as energy transmitter devices herein). For example, an EH UE may indicate multiple time offsets (e.g., each time offset includes multiple time slots), where each offset may be associated with an EH UE behavior. In some examples, the EH UE may indicate multiple time offsets directly to one or more ET UEs or to a network entity associated with one or more ET UEs. Additionally or alternatively, the EH UE may indicate a timing limit that indicates a time interval during which the EH UE requests to receive a certain amount of energy from the ET UE. In some examples, in the case where the ET UE receives multiple charging requests from multiple EH UEs, the network entity may configure a charging scheme to the ET UE via radio resource control (RRC) signaling. For example, if the ET UE concurrently receives EH requests from two EH UEs such that both EH requests can be satisfied within the corresponding time interval indicated by each EH UE, the ET UE prioritizes the order of charging based on which EH requests greater energy, has a lower request time interval, or a combination thereof.

[0006] In some cases, the ET UE may report an energy capability message to the network entity, which indicates the energy budget that the ET UE can allocate over a duration. For example, the ET UE may indicate how many energy requests it can supply during the configured duration and how many units of energy the ET UE can provide for each request. Thus, the ET UE may receive one or more energy requests such that the requested aggregate energy satisfies the energy budget of the ET UE.

[0007] A method for wireless communication at an energy receiver device is described. The method may include: sending a first indication of a duration for performing an EH procedure with an ET device to the energy receiver device; sending a second indication of a set of time offsets, each time offset in the set of time offsets being associated with an operating mode in a set of operating modes of the energy receiver device; and performing the EH procedure during the duration according to the set of time offsets and the associated operating mode in the set of operating modes.

The apparatus may include a processor, a memory coupled to the processor (e.g., operatively, communicatively, functionally, electronically, or electrically), and instructions stored in the memory.

[0059] In some examples of wireless communications, one or more wireless devices (e.g., user equipment (UE)) may participate in an energy harvesting (EH) procedure or process to collect energy from various sources (e.g., heat sources, vibration sources, motion sources, radio frequency (RF) sources, other sources, or any combination thereof) for operation. For example, if an EH UE (e.g., an energy receiver device) does not have sufficient energy for communication or other operations, the EH UE may participate in an EH procedure to accumulate energy from an energy transmitter (ET) device (e.g., an ET UE) for communication or other operations.

[0060] In some examples, multiple EH UEs (which may also be or be referred to as energy receiver devices herein) and ET UEs (which may also be or be referred to as energy transmitter devices herein) may operate in a wireless communication system, wherein each EH UE may use a different level of energy over a period of time, and each ET UE may be able to provide a different level of energy over a period of time. Thus, a first ET UE may not be able to provide the energy requested by the first EH UE, while a second ET UE may have sufficient energy to perform multiple EH procedures with multiple EH UEs. Additionally or alternatively, the first EH UE may have a lower time constraint for receiving energy than the second EH UE, but may not have the ability to indicate the time constraint to the ET UE. In the absence of capability messaging from the EH UE indicating the amount of energy and the duration of receiving the energy, the ET UE may not be able to determine how to prioritize multiple EH procedures. Additionally or alternatively, the ET UE may not be able to indicate the amount of energy that the corresponding ET UE may send during a time period.

[0061] Thus, the network may prioritize charging a set of EH UEs using a set of ET UEs according to the techniques described herein. For example, an EH UE may indicate multiple time offsets (e.g., each time offset includes multiple time slots), each of which is associated with an EH UE behavior. In some examples, the EH UE may indicate multiple time offsets directly to one or more ET UEs or to a network entity associated with one or more ET UEs. Additionally or alternatively, the EH UE may indicate a timing limit that indicates a time interval in which the EH UE requests to receive a certain amount of energy from the ET UE. In some examples, in the case where the ET UE receives multiple charging requests from multiple EH UEs, the network entity may configure a charging scheme to the ET UE via radio resource control (RRC) signaling. For example, if the ET UE concurrently receives an EH request from two EH UEs, so that both EH requests can be satisfied within the corresponding time interval indicated by each EH UE, the ET UE prioritizes the order of charging based on which EH requests a larger amount of energy, has a lower request time interval, or a combination thereof.

[0062] In some cases, the ET UE may report an energy capability message to the network entity, which indicates the energy budget that the ET UE can allocate over a duration. For example, the ET UE may indicate how many energy requests it can supply during the configured duration and how many units of energy the ET UE can provide for each request. Thus, the ET UE may receive one or more energy requests such that the requested aggregate energy satisfies the energy budget of the ET UE.

[0063] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated by and described with reference to timing diagrams and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to time domain behavior of EH devices and energy request indications.

[0064] Figure 1 An example of a wireless communication system 100 supporting time domain behavior and energy request indication of an EH device 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.

[0065] 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, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within 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 within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0066] 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 in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 Communicate with other UEs 115 or network entities 105 as shown.

[0067] 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.

[0068] In some examples, the network entities 105 may communicate with the core network 130, or communicate with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication 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 via the backhaul communication link 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), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0069] 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 giga-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).

[0070] 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)).

[0071] 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, or 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 each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 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 different ones 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 an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0072] 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 terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. 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 cases, 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.

[0073] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support the time domain behavior and energy request indication of the EH device as described herein. For example, some operations described as being performed by the UE 115 or the network entity 105 (e.g., the base station 140) may be additionally or alternatively performed by one or more components of the decomposed RAN architecture (e.g., the IAB node 104, the DU 165, the CU 160, the RU 170, the RIC 175, the SMO 180).

[0074] 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 terminology, where "device" may also be referred to as a unit, a station, a terminal, a client, or the like. 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 multimedia / entertainment device (e.g., a radio, an MP3 player, or a video device), a camera, a gaming device, a navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), Beidou, GLONASS or Galileo, ground-based equipment, etc.), a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), a drone, a robot / robotic device, a vehicle, an in-vehicle device, a meter (e.g., a parking meter, an electricity meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washing machine, a dryer), a location tag, a medical / health care device, an implant, a sensor / actuator, a display, or any other suitable device or personal computer configured to communicate via a wireless or wired medium. 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 appliances or vehicles, meters, etc.

[0075] The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115 which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0076] 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) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting 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).

[0077] The signal waveform transmitted via 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 employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The amount 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 a relatively higher amount of resource elements (e.g., in the transmission duration) and a relatively higher order of the modulation scheme may correspond to a relatively higher communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0078] The time interval for the network entity 105 or the UE 115 may be expressed in multiples 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 supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the 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).

[0079] 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 appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0080] A subframe, slot, mini-slot, or 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 transmit time interval (TTI). In some examples, the TTI duration (e.g., the amount 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)).

[0081] Physical channels may be multiplexed using carriers for communication according to various techniques. Physical control channels and physical data channels may be multiplexed via downlink carriers for signaling, for example, 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 of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE115 may monitor or search a 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 a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded 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 multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0082] 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.

[0083] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0084] 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 uses 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. In one aspect, the technology disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UE may include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UE, NB-IoT (also known as CAT NB1) UE, and other types of UE. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), and mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0085] Some UEs 115 may be configured to employ an operating mode 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 at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating using 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.

[0086] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or 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.

[0087] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via 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 communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group may be outside 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, a group of UEs 115 communicating via D2D communication 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, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0088] 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 (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access layer (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 via user plane entities, which may provide IP address allocation and other functions. The user plane entity may be connected to IP services 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0089] 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 kilohertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which 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. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0090] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating using unlicensed RF spectrum bands, devices such as network entities 105 and UEs 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0091] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that 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 may 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, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple 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 include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0092] 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 conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed 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).

[0093] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.

[0094] In some examples of the wireless communication system 100, one or more UEs 115 may participate in an EH procedure or process to collect energy from various sources for operation. For example, if an EH UE 115 (e.g., an energy receiver device) does not have sufficient energy for communication or other operations, the EH UE 115 may participate in an EH procedure to accumulate energy from an ET device (e.g., ETUE 115) for communication or other operations.

[0095] In some examples, multiple EH UEs 115 and ET UEs 115 may operate in a wireless communication system, wherein each EH UE 115 may use different levels of energy over a period of time, and each ET UE 115 may be able to provide different levels of energy over a period of time. Thus, the wireless communication system 100 may prioritize charging of a set of EH UEs 115 using a set of ET UEs 115 according to the techniques described herein. For example, the EH may indicate multiple time offsets (e.g., each time offset includes multiple time slots), wherein each offset may be associated with an EH UE 115 behavior. In some examples, the EH UE 115 may indicate multiple time offsets directly to one or more ET UEs 115 or to a network entity associated with one or more ET UEs 115. Additionally or alternatively, the EH UE 115 may indicate a timing restriction indicating a time interval during which the EH UE 115 requests to receive a certain amount of energy from the ET UE 115. In some examples, in the event that the ET UE 115 receives multiple charging requests from multiple EH UEs 115 , the network entity may configure a charging scheme to the ET UE 115 via RRC signaling.

[0096] In some cases, the ET UE 115 may report an energy capability message to the network entity, which indicates the energy budget that the ET UE 115 can allocate over a duration. For example, the ET UE 115 may indicate how many energy requests it can supply during the configured duration and how many units of energy the ET UE 115 can provide for each request. Thus, the ET UE 115 may receive one or more energy requests such that the total energy requested satisfies the energy budget of the ET UE 115.

[0097] Figure 2An example of a wireless communication system 200 that supports time domain behavior and energy request indication of EH devices according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement one or more aspects of the wireless communication system 100. For example, the EH UE 210 and the ET UE 205 can be respective examples of the UE 115, the network entity 105-a can be an example of the network entity 105, and the geographic coverage area 110-a can be an example of the geographic coverage area 110, as shown in reference Figure 1 Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in this disclosure.

[0098] In some examples of the wireless communication system 200, one or more wireless devices (e.g., EH UE 210 and ET UE 205) may participate in EH procedures 230 or processes to collect energy from various sources for operation. For example, the EH UE 210 may be an example of a zero-power UE 115 (e.g., an IoT device) and may not have enough energy to perform communications or other operations for a duration exceeding a configuration. Thus, the EH UE 210 may participate in the EH procedures 230 to accumulate energy from a second device (e.g., ET UE 205). In some examples, the wireless communication system may include multiple EH UEs 210 that may request corresponding EH procedures 230 and multiple ET UEs 205 that may provide energy to the EH UE 210. In such examples, each EH UE 210 may use different levels of energy over a period of time, and each ET UE 205 may be able to provide different levels of energy over that period of time. Thus, it may be advantageous for each EH UE 210 to indicate the amount of energy requested and a timing parameter indicating an upper limit on when the requested energy is received, so that the associated network can prioritize charging of the respective EH UE 210. Additionally or alternatively, it may be advantageous for each ET UE 205 to send an energy capability message to the network indicating the energy budget that the given ET UE 205 can allocate for a duration.

[0099] Thus, the wireless communication system 200 may introduce signaling of time domain behavior at the EH UE 210, which may be associated with an expected charging rate and a timing parameter indicating an upper limit of when the EH UE 210 requests to perform the EH procedure 230. For example, the EH UE 210 may send an EH request message 215 to the network entity 105-a, one or more ET UEs 205, or both. In an example where the EH UE 210 sends the EH request message 215 to the network entity 105-a, the network entity 105-a may forward the EH request message 215 to the ET UE 205 (e.g., as described in the example above). Figure 2Additionally or alternatively, the EH UE 210 may send an EH request message 215 directly to the ET UE 205 (eg, Figure 2 (not shown in the example).

[0100] In some examples, the EH UE 210 may indicate the time offsets and the operations associated with each of the time offsets (e.g., the corresponding operations, or the operations or operation modes corresponding to the time offsets) at the EH UE 210 to the network entity 105-a or one or more ET UEs 205. For example, the indication may include information synonymous with Table 1:

[0101] Timing offset (time slot) EHUE 210 Operation Before Timing Shift 10 Full UE functionality 40 Prohibit data transmission 80 Digital circuit off

[0102] Table 1: Example of timing offset and associated EH UE operations

[0103] It will be appreciated that while Table 1 provides an example of three timing offsets associated with three EH UE 210 operations, the EH UE 210 may indicate any number of timing offsets associated with any number of EH UE 210 operations.

[0104] In some examples, the indication of the time offset may be included in the EH request message 215, may be part of a dynamic indication, may be part of a separate control message (e.g., included in an RRC, MAC control element (MAC-CE), uplink control information (UCI)), or a combination thereof. Additionally or alternatively, the EH UE 210 may include a maximum limit (e.g., N2_energy_max time limit) in the EH request message 215 for the time in which the energy request is expected to be satisfied. Thus, the EH UE 210 may expect the ET UE 205 to satisfy the EH request (e.g., perform the associated EH procedure 230) within the N2_energy_max time limit. In some examples, the N2_energy_max time limit may be an indication in terms of time slots, frames, seconds, etc.

[0105] Based on receiving the EH request message 215 from the EH UE 210 (e.g., directly or via the network entity 105-a acting as a relay), the ET UE 205 may determine whether the ET UE 205 can meet the requested amount of energy during the N2_energy_max time limit. If the ET UE 205 determines that it cannot meet the EH request, the ET UE 205 may ignore the EH request message 215. Thus, if the EH UE 210 does not receive an acknowledgment message in response to the EH request message 215 from the ET UE 205 during a configured timing threshold, the EH UE 210 may resend the EH request message 215 to one or more other ET UEs 205 (e.g., directly or via the network entity 105-a acting as a relay). Additionally or alternatively, if the ET UE 205 determines that it cannot satisfy the EH request, the ET UE 205 may send an indication to the EH UE 210 (e.g., directly or via the network entity 105-a acting as a relay) that it may not be able to satisfy the EH request. Based on receiving the indication from the ET UE 205, the EH UE 210 may resend the EH request message 215 to one or more other ET UEs 205 (e.g., directly or via the network entity 105-a acting as a relay). Additionally or alternatively, the EH UE 210 may also indicate expected operations before and after the N2_energy_max time limit. For example, two expected operations may be indicated, such as no data reception at the EH UE 210 before the N2_energy_max time limit and digital circuit switching after the N2_energy_max time limit.

[0106] Based on the wireless communication system 200 supporting multiple EH UEs 210, the ET UE 205 may receive multiple EH request messages 215, each of which may belong to a corresponding EH UE. In some examples, the ET UE 205 may also be configured with a duration in which charging or communicating data is performed, during which the ET UE 205 may not be able to perform the EH procedure 230. Thus, the ET UE 205 may receive RRC signaling, or may be dynamically indicated when receiving multiple EH request messages 215 that overlap at least partially in time. For example, the ET UE 205 may receive a multi-EH procedure configuration 225 from the network entity 105-a. If two EH request messages 215 are received at the ET UE 205 and both can be satisfied within the corresponding indicated time interval (e.g., before the corresponding N2_energy_max time limit), the ET UE 205 may perform both of the associated EH procedures. In some examples, the ET UE 205 may prioritize the multiple EH procedures 230 according to the multiple EH procedures configuration 225. For example, the ET UE 205 may prioritize the EH procedure 230 having a shorter N2_energy_max time limit among the two EH procedures 230. Additionally or alternatively, the ET UE 205 may execute the multiple EH procedures 230 concurrently.

[0107] Based on the specific input power to the EH UE 210 and the power consumed at the EH UE 210 during the activity, a device activity cycle may be configured at the EH UE. That is, if the input power from the EH protocol 230 is P x And P x The RF, light / laser to DC conversion efficiency is η x , then the collected power can be P x ·η x Thus, if the integrated circuit (IC) power of the EH UE 210 is P during the reading duration of Y time units, y , then the conditions for operating the EH UE 210 may be associated with Formula 1:

[0108] P x ·η x ·X ≥ P y ·Y

[0109] Where X can be the conversion efficiency of EH UE 210 at η x The collected power P is received x Therefore, the EH UE 210 can configure the collection duration X according to Formula 2:

[0110]

[0111] Based on the determined collection duration X, the EH UE 210 may also determine the EH to activity time ratio according to Formula 3:

[0112]

[0113] Thus, the EH UE 210 may use the collection duration X and the EH to active time ratio to determine the N2_energy_max time limit to be indicated in the EH request message 215 .

[0114] In some examples, the ET UE 205 may define a maximum amount of time (e.g., N2_energy_max) that the ET UE 205 may use to participate in one or more EH procedures 230. For example, the ET UE 205 may send an EH capability message 220 to the network entity 105-a, the EH UE 210, or both (e.g., directly or via the network entity 105-a acting as a relay). In some examples, the EH capability message 220 may include an indication of N2_energy_max. Thus, the network entity 105-a configures the ET UE 205 with an amount of time (e.g., N2_energy) for the ET UE 205 to perform the EH procedure 230, which may be less than N2_energy_max. In the example of optical energy transfer, N2_energy may be associated with the time between receiving an energy request message and preparing an optical or laser signal for the associated EH procedure 230.

[0115] In some examples, N2_energy may vary with: frequency band, frequency band combination, carrier, carrier combination, energy waveform, or a combination thereof. In some examples, the energy waveform may be single-tone, multi-tone, OFDM, or DFT-S-OFDM, quadrature amplitude modulation (QAM) (e.g., single carrier QAM (SC-QAM)), pulse amplitude modulation (PAM), or a combination thereof. In some examples, the waveform may have an associated modulation, such as amplitude shift keying (ASK), phase shift keying (PSK), quadrature PSK (QPSK), M-ary PSK (MPSK), multi-pulse pulse position modulation (M-PPM), on-off keying (OOK), Gaussian, Bernoulli, Gold, DFT, Reed-Solomon, Zadoff-Chu, or a combination thereof. In some examples, a sounding reference signal (SRS) or SRS-like signal, a control state information reference signal (CSI-RS) or CSI-RS-like signal, data or data-like energy signal, or a repetition of another signal may be used as a means of carrying the corresponding waveform and modulation.

[0116] In some examples, the EH UE 210 or the network entity 105-a may indicate to the ET UE 205 the time between the downlink control information (DCI) slot and the energy slot (e.g., K2_energy, similar to the time between the DCI and the physical uplink shared channel (PUSCH)). If the ET UE 205 is unable to meet the parameters of K2_energy, the ET UE 205 may ignore the EH request. Additionally or alternatively, the ET UE 205 may send an indication indicating that it may not be able to meet the EH request. Additionally or alternatively, the ET UE 205 may be able to meet a portion of the EH request and thereby may perform a partial EH procedure 230 with the EH UE 210.

[0117] In some examples, the ET UE 205 may configure an energy budget for executing an EH procedure 230 with multiple EH UEs 210. For example, the ET UE 205 may configure a total energy budget of E per T seconds. Thus, the ET UE 205 may execute a first EH procedure 230 with power P1 within T1 and a second EH procedure 230 with power P2 within time T2, such that P1T1+P2T2≤E, where T1+T2≤T. For a fixed energy budget design in which the ET UE 205 may spend E energy units per T time units, the ET UE 205 may use an average transmit power E / T. For example, if the ET UE 205 transmits using E / T for each EH procedure 230, the ET UE 205 may define T1 according to the energy requested for the first EH procedure 230 (e.g., E1) and define T2 according to the energy requested for the second EH procedure 230 (e.g., E2). Additionally or alternatively, the ET UE 205 may assign a time allocation (eg, a fixed configuration grant for charging assigned by the network entity 105 - a or reserved by the ET UE 205 ) and assign power levels P1 and P2 according to E1 , E2 , T1 , and T2 .

[0118] In some examples, the ET UE 205 may configure multiple EH procedures 230 based on the specific implementation of the ET UE 205. Additionally or alternatively, the ET UE 205 may configure multiple EH procedures 230 according to controlling the power output to the corresponding EH UE 210 (e.g., similar to the power control procedure). Thus, one of the various methods for configuring multiple EH procedures 230 may be signaled to the ET UE 205 via a configuration message (e.g., multiple EH procedures configuration 225) or a resource pool level configuration via a side link, a band or a band comb, or a carrier or a carrier comb. In some examples, the ET UE 205 may indicate a preference for one of the various methods to the network entity 105-a via signaling.

[0119] In the example where the network entity 105-a sends one or more EH request messages 215 to the ET UE 205, it may be advantageous for the network entity 105-a to determine the maximum energy budget that the ET UE 205 can allocate. Thus, the ET UE 205 may send an initial or default value E of a fixed energy budget design as part of the EH capability message 220. Thus, the network entity 105-a may configure an energy configuration (e.g., E_config) that may be less than E to the ET UE 205. In some examples, E_config and E may change dynamically. For example, E may depend on the current battery state of the ET UE 205 or the number of other tasks that the ET UE 205 may perform. Thus, the ET UE 205 may dynamically indicate an update to the value of E to the network entity 105-a, and the network entity 105-a may send an updated value of E_config based on the indication. In some examples, the indication of E and E_config may be sent via L1, L2, and L3 communications.

[0120] In some cases, the energy power allocation to the EH UE 210 may be dynamic (e.g., the energy E may be fixed, but the power and time may vary). Additionally or alternatively, the power and time of the EH procedure 230 may be fixed. Thus, the network entity 105-a may indicate to the ET UE 205 whether to use a fixed energy level (e.g., E / T remains constant) or a dynamic power level (e.g., E / T may be different for each EH procedure 230) for energy grants. Figure 3 and Figure 4 ) describes other specific implementations of fixed energy budget design.

[0121] Figure 3 An example of a multi-EH timing diagram 300 supporting time domain behavior and energy request indication of EH devices according to one or more aspects of the present disclosure is illustrated. In some examples, the multi-EH timing diagram 300 can implement one or more aspects of the wireless communication system 100 and the wireless communication system 200. For example, the EH UE 310-a, the EH UE 310-b, and the ET UE 305 can be as described in reference Figure 1 A corresponding example of the described UE 115. Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in this disclosure.

[0122] like Figure 3As illustrated, the ET UE 305 may have an energy budget 315 for a given time period 330. For example, at the beginning of each time period 330-a, the ET UE 305 may perform an energy budget update such that the energy budgets 315-a, 315-d, and 315-e may be configured amounts of energy (e.g., E reference) that the ET UE 305 may use for the EH procedure 320 during the time period 330. Figure 2 ). Thus, the ET UE 305 executes a plurality of EH procedures 320 according to the energy budget 315 allocated for the corresponding time period 330.

[0123] In some examples, EH UE 310-a and EH UE 310-b may be examples of radio frequency identification (RFID) tags with corresponding ICs. In some examples, EH UE 310-a may have a first IC that may use a certain amount of power Py1, and EH UE 310-b may have a second IC that uses power Py1. Thus, if EH UE 310-a operates for a time of X1, the energy consumed by EH UE 310-a may be Py1*X1. Additionally, if EH UE 310-b operates for a time of X2, the energy consumed by EH UE 310-a may be Py2*X2. Thus, EH UE 310-a may have an energy causality constraint according to Formula 4:

[0124] Pc1*η1*T1≥Py1*X1

[0125] Where PC1 can be the input power from the EH procedure 320-a, η1 can be the RF to DC conversion efficiency of the first IC, and T1 can be the duration 325-a of the EH procedure 320-a. Thus, Pc1*T1 multiplied by the associated power level 335-a (PL1) can equal the requested transmit energy for the EH procedure 320-a. Thus, the requested transmit energy can be related to the parameters Py1, X1, η1, and PL1 according to Formula 5:

[0126]

[0127] A similar process for determining the transmit energy for the EH procedure 320-b may be determined according to Equation 6:

[0128]

[0129] Where Pcl is the input power from the EH procedure 320-b, T2 is the duration 325-b of the EH procedure 320-b, PL2 is the power level 335-b for the EH procedure 320-b, and η2 is the RF to DC conversion efficiency of the second IC. Thus, the ET UE 305 can execute both the EH procedure 320-a and the EH procedure 320-b within the time period 330-a, so that the sum of the energy used for the two EH procedures 320 does not exceed the energy budget 315-a. For example, the ET UE 305 can execute the EH procedure 320 according to Formula 7:

[0130]

[0131] By operating according to Formula 7, the ET UE 305 may execute the EH procedure 320-a so that the resulting energy budget 315-b may be equal to the difference between the energy budget 315-a and the transmit energy-a for the EH procedure 320 according to Formula 5. In some examples, the ET UE 305 may also execute the EH procedure 320-b so that the resulting energy budget 315-c may be equal to the difference between the energy budget 315-b and the transmit energy for the EH procedure 320-b according to Formula 6. In some cases, the transmit energy for the EH procedure 320-b may be greater than the energy budget 315-b. Thus, if the energy budget 315-b satisfies a defined percentage of the energy request of the EH UE 310-b, the ET UE 305 may send the remaining energy budget 315-b to the EH UE 310-b (e.g., execute a portion of the EH procedure 320). Additionally or alternatively, the ET UE 305 may wait for the next time period 330-b, where the energy budget 315-d may be updated during the time period 330-b and the EH procedure 320-b is executed. Although the multi-EH timing diagram 300 illustrates the ET UE 305 executing two EH procedures 320 during the time period 330-a, it is understood that the ET UE 305 may execute any number of EH procedures 320 during the time period according to the techniques and formulas described herein.

[0132] In some cases, the ET UE 305 may also determine the number of configuration or scheduling grants to be used to deliver the corresponding EH procedure 320. For example, assuming that the allocated time is Tx, the power is Px, and the energy is Ex, the energy delivered per grant may be configured via a fixed power scheme (e.g., Ex=Px*Tx) or a fixed energy scheme (e.g., Px=Ex / Tx). In some examples, the ET UE 305 may maintain a fixed power scheme to maintain phase continuity, and thus Tx may be configured to determine the number of symbols used to maintain phase continuity between multiple grants. For example, the number of grants for the EH procedure 320-a may be determined according to Formula 8:

[0133]

[0134] In the example of a fixed energy scheme, the ET UE 305 may determine the number of grants for the EH procedure 320 - a according to Formula 9:

[0135]

[0136] In some examples, the ET UE 305 may multiplex data transmissions with energy signals for the EH procedure 320 to maintain phase continuity. In some cases, the ET UE 305 may use a fully configured time allocation for a given energy grant or use a partial time allocation according to the techniques described herein.

[0137] Figure 4 An example of a fixed energy request timing diagram 400 that supports time domain behavior and energy request indication of an EH device according to one or more aspects of the present disclosure is illustrated. In some examples, the fixed energy request timing diagram 400 can implement one or more aspects of the wireless communication system 100 and the wireless communication system 200 and the multi-EH timing diagram 300. For example, the ET UE 405 can be as described in reference Figure 1 The example of UE 115, and energy budget 410 and time period 425 may be referenced Figure 3 315 and corresponding examples of energy budgets 315 and time periods 330. Although examples are discussed herein, any number of devices and device types may be used to implement the specific implementations described in this disclosure.

[0138] In some examples, the ET UE 405 may indicate the number of energy requests 420 that it can perform within a configured time period 425. In some cases, the time period 425 may be pre-configured at the ET UE 405 or configured via network signaling. In some examples of indicating the number of energy requests 420, the ET UE 405 may also indicate the number of energy units 415 that the ET UE 405 can satisfy for each energy request 420. In some examples, the ET UE 405 may indicate the number of energy requests 420, the time period 425, and the number of energy units 415 per request via L1, L2, or L3 signaling. Additionally or alternatively, the ET UE 405 may report the remaining number of energy requests 420 during the time period 425 to the associated network entity 105 or the associated EH UE.

[0139] If the energy delivery design is based on the number of energy requests 420 and the number of energy units 415 per energy request 420, the ET UE 405 may determine the number of energy units 415 it can use to perform non-EH operations. Thus, the ET UE 405 may calculate how many remaining energy units 415 it can use to satisfy the energy requests 420. For example, if the ET UE 405 is configured to satisfy 10 energy requests, each of which has a defined number of energy units 415, the associated EH UE may request a number of energy units less than or equal to 10. Thus, based on the configuration of the number of energy units 415 per energy request 420, each associated EH UE may report the number of energy units 415 or the number of energy requests 420 according to the configuration. In some examples, the ET UE 405 may also indicate the maximum number of energy requests 420 (e.g., E_T requests) that each EH UE may send during the configured duration. In some cases, the E_T request may be configured by the network entity 105 or the ET UE 405 via L1, L2, and L3 signaling.

[0140] refer to Figure 3 Based on a given IC of an EH UE with an RF to DC conversion n that may depend on the input power strength, it may be advantageous to use a higher power level for a short duration. Thus, the ET UE 405 may configure the energy unit 415 to have a power level above a first configuration threshold and a duration below a second configuration threshold.

[0141] In the example of the fixed energy request timing diagram 400, the ET UE 405 may configure an energy budget 410-a including four energy units 415 for a time period 425. The ET UE 405 may receive an energy request 420-a associated with a first EH UE that may request one energy unit 415. Based on executing the EH procedure with the first EH UE, the ET UE 405 may have an energy budget 410-b including three energy units 415. In some examples, the ET UE 405 may receive an energy request 420-b associated with a second EH UE that may request one energy unit 415. Based on executing the EH procedure with the second EH UE, the ET UE 405 may have an energy budget 410-c including two energy units 415. In some cases, at the end of the time period 425, the ET UE 405 may update the energy units 415 of the energy budget 410-d.

[0142] Figure 5An example of a process flow 500 for supporting time domain behavior and energy request indication of an EH device according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 500 can implement aspects of the wireless communication system 100, the wireless communication system 200, the multi-EH timing diagram 300, the fixed energy request timing diagram 400, or a combination thereof. The process flow 500 includes an ET UE 505 and an EH UE 510, which can be reference Figure 1 UE 115 of the present invention. The following alternative examples may be implemented in which some of the steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or other steps may be added. In addition, although the process flow 500 shows the process between a single ETUE 505 and a single EHUE 510, it should be understood that these processes may occur between any number of network devices and network device types.

[0143] At 515, the EH UE 510 may receive a wake-up indication (WUI) message from a network device (e.g., from an associated network entity 105, from an ET UE 505, or another wireless device associated with the EH UE 510). In some examples, the WUI may instruct the EH UE 510 to wake up from a sleep mode for a configured duration to perform one or more operations. At 520, the EH UE 510 may send a wake-up confirmation (WUA) message to the network device in response to the WUI message.

[0144] At 525, the EH UE 510 may receive an EH procedure configuration from the ET UE 505. For example, the EH procedure configuration may indicate a maximum requested amount for EH procedures with the ET UE 505. In some examples, the EH procedure configuration may be transmitted directly from the ET UE 505 or relayed via an associated network entity 105.

[0145] At 530, the EH UE 510 may send a first indication of a duration for the EH UE 510 to perform the EH procedure with the ET UE 505. In some examples, the first indication may include a duration threshold identifying a maximum duration for the EH UE 510 to perform the EH procedure. In some examples, the duration threshold may indicate an amount of slots, mini-slots, symbols, subframes, frames, seconds, or any combination thereof.

[0146] At 535, the EH UE 510 may send a second indication of a set of time offsets, each time offset in the set of time offsets being associated with an operating mode in the set of operating modes for the energy receiver device. In some examples, the EH UE 510 may send the first indication and the second indication in one EH request message.

[0147] At 540, the EH UE 510 may send a third indication of a first operating mode of the EH UE 510 applicable at the EH UE 510 before the duration and a second operating mode applicable at the EH UE 510 after the duration. In some examples, the EH UE 510 may send the first indication, the second indication, and the third indication to the ET UE 505 directly or via an associated network entity 105 acting as a relay.

[0148] In some examples, at 545, the EH UE 510 may receive a message from the ET UE 505 indicating that the ET UE 505 refuses to perform the EH procedure. Additionally or alternatively, the EH UE 510 may not receive a response to the first indication from the ET UE 505 within a configured threshold.

[0149] Thus, at 550, the EH UE 510 may resend the first indication based on not receiving a response to the first indication during a configured threshold or based on receiving a message rejecting the EH procedure. In some examples, the EH UE 510 may resend the first indication to the ET UE 505, one or more other ET UEs 505s, a network entity 105 that may act as a relay to one or more other ET UEs 505s, or a combination thereof.

[0150] At 555 , the EH UE 510 and the ET UE 505 may perform EH procedures during the duration according to the set of time offsets and the associated operating mode in the set of operating modes.

[0151] Figure 6 An example of a process flow 600 for supporting time domain behavior and energy request indication of an EH device according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 600 can implement aspects of the wireless communication system 100, the wireless communication system 200, the multi-EH timing diagram 300, the fixed energy request timing diagram 400, or a combination thereof. The process flow 600 includes an ET UE 605, an EH UE 610-a, and an EH UE 610-b, which can be reference UEs. Figure 1 UE 115 of the present invention. The following alternative examples may be implemented in which some of the steps are performed in a different order than described or are not performed at all. In some cases, the steps may include additional features not mentioned below, or other steps may be added. In addition, although the process flow 600 shows the process between a single ET UE 605 and two EH UEs 610, it should be understood that these processes may occur between any number of network devices and network device types.

[0152] At 615, the ET UE 605 may receive a control signal indicating a procedure for executing multiple EH procedures for conflicting energy request messages. In some examples, the ET UE 605 may receive the control signal from an associated network entity 105 or an EH UE 610. In some examples, the procedure for executing EH procedures for conflicting energy request messages may indicate prioritizing the EH procedures based on a requested energy amount and an associated duration for each respective EH procedure in the multiple EH procedures.

[0153] At 620, the ET UE 605 may send an energy capability message to the EH UE 610-a and the EH UE 610-b. In some examples, the energy capability message may include an indication of the energy transmission capability of the ET UE 605, wherein the energy transmission capability may identify a first amount of energy that the ET UE 605 may be able to provide to the EH UE 610-a and 610-b for the duration of the EH procedure. In some examples, the ET UE 605 may also send (e.g., as part of the energy capability message or in a separate control message) an indication of the amount of EH procedures that may be executed during the duration and the amount of energy for each of the number of EH procedures.

[0154] Additionally or alternatively, the ET UE 605 may send an update to the energy transmission capability, which may change the first amount of energy that the ET UE 605 may provide to the one or more EH UEs 610 during the second duration of the EH procedure. In some examples, the first amount of energy that the ET UE 605 may provide to the one or more EH UEs 610 may be based on one or more RF bands associated with the ET UE 605, one or more carriers associated with the ET UE 605, a waveform type used for the EH procedure, or any combination thereof.

[0155] At 625, the ET UE 605 may perform EH energy configuration. For example, the ET UE 605 may receive a control message from the associated network entity 105 in response to the energy transmission capability, the control message identifying a configured energy amount for the ET UE 605 that may be less than or equal to the first energy amount. In some examples, the ET UE 605 may also receive an update to the configured energy amount based on a battery status of the ET UE 605, an operating mode of the ET UE 605, or both.

[0156] At 630, the ET UE 605 may receive an energy request message indicating a time associated with a duration for performing the EH procedure and a second energy amount for the EH procedure for the energy receiver device, the second energy amount being based on the first energy amount identified by the energy transmission capability of the ET UE 605. In some examples, the second energy amount indicated in the energy request message may be based on an energy amount for each procedure of the EH procedure that the ET UE 605 indicates to be used for the amount.

[0157] Additionally or alternatively, the ET UE 605 may receive multiple energy request messages from multiple EH UEs 610. For example, at 630-a, the ET UE 605 may receive a first energy request message from the EH UE 610-a indicating a third energy amount and a first duration for executing a first EH procedure, and at 630-b, the ET UE 605 may receive a second energy request message from the EH UE 610-b indicating a fourth energy amount and a second duration for executing a second EH procedure. In some cases, the first duration and the second duration overlap at least partially in time. In some examples, the sum of the third energy amount and the fourth energy amount may be less than or equal to the first energy amount, and the sum of the first duration and the second duration may be less than or equal to the duration.

[0158] In some cases, the ET UE 605 may receive (e.g., from the EH UE 610-b) a second EH request message indicating a second time that is at least partially outside the duration for performing the EH procedure. Thus, at 635, the ET UE 605 may send a message rejecting the second EH request message based on the second time being at least partially outside the duration. Additionally or alternatively, the ET UE 605 may perform a portion of the EH procedure at least partially outside the duration according to the second time in response to receiving the second EH request message.

[0159] At 640, the ET UE 605 may perform multiple EH procedures with multiple EH UEs 610. For example, at 640-a, the ET UE 605 may perform a first EH procedure with a first energy receiver device for a first duration according to the procedure configured at 615. At 640-b, the ET UE 605 may perform a second EH procedure with a second energy receiver device for a second duration according to the procedure configured at 615. In some examples, the ET UE 605 may multiplex the EH procedure with data transmission to the corresponding EH UE 610.
