Description

Technical Field

[0001] The following relates to wireless communications, including power control for power providers and energy harvesting transmitters. Background Art

[0002] 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

[0003] The described technology relates to improved methods, systems, devices and apparatuses for supporting power control for power providers and energy harvesting transmitters. In general, the technology described herein can implement power control for energy providing wireless devices (e.g., power providers) and energy harvesting wireless devices (e.g., energy harvesting transmitters). For example, the energy providing wireless device may communicate first control signaling indicating multiple energy transfer power control schemes, wherein each energy transfer power control scheme may indicate how the energy providing wireless device determines a transmit power level for transmitting one or more energy transfer signals. In some cases, the energy providing wireless device may receive a second control signaling indicating activation of a first energy transfer power control scheme in the multiple energy transfer power control schemes. Additionally, the energy providing wireless device may communicate a scheduling message to one or more energy harvesting wireless devices to schedule the transmission of energy transfer signals, and may transmit the energy transfer signals according to the transmit power level determined by the first energy transfer power control scheme. In some cases, one or more energy harvesting wireless devices may perform an energy harvesting procedure based on receiving the energy transfer signal to charge an energy storage device associated with the corresponding energy harvesting wireless device.

[0004] Similarly, the energy harvesting wireless device may communicate first control signaling indicating a plurality of data transmit power control schemes, wherein each data transmit power control scheme may indicate how the energy harvesting wireless device is to determine a transmit power level for transmitting one or more data messages. In some cases, the energy harvesting wireless device may receive second control signaling indicating activation of a first data transmit power control scheme in the plurality of data transmit power control schemes. Additionally, the energy harvesting wireless device may communicate a scheduling message to schedule the transmission of the data message, and may transmit the data message at a transmit power level determined by the first data transmit power control scheme.

[0014] Some wireless communication systems may support energy harvesting. For example, an energy harvesting wireless device may harvest energy from the environment in which the energy harvesting wireless device is located and may store the energy (e.g., in a rechargeable battery). In some cases, the energy harvesting wireless device may harvest energy from an energy transfer signal sent by an energy providing wireless device. That is, the energy providing wireless device may send an energy transfer signal at a power level, and the energy harvesting wireless device may receive the energy transfer signal and execute an energy harvesting procedure to charge an energy storage device associated with the energy harvesting wireless device. However, conventional technology may not support power control for energy providing wireless devices and energy harvesting wireless devices, which may result in inefficient operation of the energy harvesting wireless device, the energy providing wireless device, or both.

[0015] Thus, the techniques described herein may support power control for energy transmission of energy transfer signals by an energy providing wireless device and energy transmission of data messages by an energy harvesting wireless device. For example, a wireless device (such as an energy providing wireless device or an energy harvesting wireless device) may support one or more power control schemes, which may be referred to as energy transfer power control schemes for energy providing wireless devices or data transmission power control schemes for energy harvesting wireless devices. Each power control scheme may specify how the wireless device determines a transmission power level for transmission of energy transfer signals (e.g., by an energy providing wireless device) or transmission of data messages (e.g., by an energy harvesting wireless device). In some examples, a first power control scheme may indicate that the transmission power level is based on an indication received in a control message from a second wireless device. In some examples, a second power control scheme may indicate that the transmission power level may be based on a power class of an energy harvesting device that receives the energy transfer signal or transmits the data message. In some examples, a third power control scheme may indicate that the transmission power level may be based on a path loss, which may be an uplink path loss, a sidelink path loss, or a downlink path loss. In some cases, the transmit power level may be based on one or more characteristics of the energy harvesting device receiving the energy transfer signal or sending the data message.

[0016] Thus, the wireless device may receive a first control message indicating a plurality of power control schemes and a second control message indicating activation of a power control scheme from the plurality of power control schemes. Thus, the wireless device may communicate a scheduling message to schedule transmission of an energy transfer signal (e.g., by an energy providing wireless device) or transmission of a data message (e.g., by an energy harvesting wireless device) and may transmit the energy transfer signal or the data message at a transmit power level determined by the activated power control scheme.

[0017] Transmitting energy transfer signals according to a centralized activated energy transfer power control scheme of the energy transfer power control scheme may support efficient energy transfer, which may result in reduced power consumption, more efficient charging, and more efficient utilization of communication resources, among other advantages. Additionally, transmitting data messages according to an activated data transmission power control scheme may result in efficient data communication by the energy harvesting device, which may result in reduced power consumption, more efficient utilization of communication resources, more efficient charging, and longer battery life, among other advantages.

[0018] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are then subsequently described in the context of a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to power control for power providers and energy harvesting transmitters.

[0019] Figure 1 An example of a wireless communication system 100 that supports power control for power providers and energy harvesting transmitters 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.

[0020] 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).

[0021] 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. The UEs 115 described herein may be capable of supporting communications with various types of devices, such as Figure 1 Other UEs 115 or network entities 105 are shown in FIG.

[0022] 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.

[0023] 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 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 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 links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 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 .

[0024] 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 terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in a clustered (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0025] 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)).

[0026] The functional split between CU 160, DU 165, and RU 170 is flexible and can support different functionality, 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 can be employed between CU 160 and DU 165, such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of a protocol stack. In some examples, CU 160 can 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 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 a protocol layer (e.g., some functions of a 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., an open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (eg, a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0027] 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 (e.g., of the RU 170) of the IAB node 104 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.

[0028] 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 power control for power providers and energy harvesting transmitters 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).

[0029] 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 appliances or vehicles, meters, etc.

[0030] 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.

[0031] The UE 115 and the network entity 105 may communicate wirelessly 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 with 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 portion (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 portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0032] 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 identified based on a channel raster used for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0033] 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).

[0034] 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 of carriers for a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). Devices of the wireless communication system 100 (e.g., a network entity 105, a UE 115, or both) may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be configured to support communications using 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 communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0035] The signal waveform transmitted via the carrier may be composed of 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 resource of a subcarrier, in which case the symbol period and the 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 a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high rate of communication. 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.

[0036] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may refer to, for example, The sampling period is seconds. For this sampling period, may indicate the supported subcarrier spacing, and 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).

[0037] 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 to the 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., The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0038] 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 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)).

[0039] Physical channels may be multiplexed according to various techniques to communicate using a carrier. Physical control channels and physical data channels may be multiplexed via a downlink carrier 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 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 candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with the 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 .

[0040] 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 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.

[0041] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide 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 acquire 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, wildlife monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0042] 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). The UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communications may include private communications or group communications 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.

[0043] 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 (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside of the coverage area 110 of the network entity 105, or may not be originally capable of or 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 examples, D2D communications may be conducted between UEs 115 without involving network entity 105.

[0044] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) using vehicle-to-network (V2N) communication, or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170), or both.

[0045] 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 stratum (NAS) functions such as mobility, authentication, and bearer management of UEs 115 served by network entities 105 (e.g., base stations 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 the 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.

[0046] 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). 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 the structure so that a macro cell provides service to a UE 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0047] The wireless communication system 100 can utilize both licensed RF spectrum bands and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to adopt licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be performed based on a carrier aggregation configuration (e.g., LAA) in combination with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.

[0048] 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 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, 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 set of multiple rows of antenna ports and multiple 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 can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0049] 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 steer 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 in a particular direction 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).

[0050] In some cases, the wireless communication system 100 may support power control for transmission of energy transfer signals by an energy providing wireless device (such as an energy providing network entity 105 or an energy providing UE 115) and energy transmission of data messages by an energy harvesting wireless device (such as an energy harvesting network entity 105 or an energy harvesting UE 115). For example, the energy providing wireless device (such as an energy providing UE 115) may receive a first control message indicating a set of energy transfer power control schemes, wherein each energy transfer power control scheme specifies how the energy providing UE 115 determines a transmit power level for transmission of energy transfer signals. In some cases, the energy providing UE 115 may receive a second control message activating a first energy transfer power control scheme in the set of energy transfer power control schemes. Additionally, the energy providing UE 115 may send a scheduling message to one or more energy harvesting wireless devices (such as an energy harvesting UE 115) to schedule the transmission of energy transfer signals. In addition, the energy providing UE 115 may send an energy transfer signal to the energy harvesting UE 115 according to the transmit power level of the first energy transfer power control scheme. In some cases, the energy harvesting UE 115 may receive the energy transfer signal and may execute energy harvesting procedures to charge an energy storage device associated with the energy harvesting UE 115 .

[0051] In another example, an energy harvesting wireless device, such as an energy harvesting UE 115, may receive a first control message indicating a set of data transmit power control schemes, wherein each data transmit power control scheme specifies how the energy harvesting UE 115 determines a transmit power level for transmission of data messages. In some cases, the energy harvesting UE 115 may receive a second control message activating a first data transmit power control scheme in the set of data transmit power control schemes. Additionally, the energy harvesting UE 115 may send a scheduling message to one or more additional wireless devices, such as the additional UE 115, scheduling the transmission of the data message. In addition, the energy harvesting UE 115 may send the data message to the additional UE 115 according to the transmit power level of the first data transmit power control scheme.

[0052] Figure 2 An example of a wireless communication system 200 that supports power control for power providers and energy harvesting transmitters according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100 or can be implemented by these aspects. For example, the wireless communication system 200 may include one or more network entities 105 (e.g., network entity 105-a) and one or more UEs 115 (e.g., UEs 115-a and 115-b), which can be reference Figure 1 Examples of the corresponding devices described. Figure 2In the example of FIG. 1 , the network entity 105 - a may be a CU 160 , a DU 165 , a RU 170 , a base station 140 , an IAB node 104 , or a Figure 1 In some cases, a UE 115-a that may be an energy provider for a UE 115-a may receive a control message 205-b that activates a first energy transfer power control scheme of a set of energy transfer power control schemes supported by the UE 115-a.

[0053] Some wireless communication systems (e.g., reduced capability (RedCap) systems, non-RedCap systems, passive Internet of Things (PIoT) systems) such as the wireless communication system 200 may support wireless devices (such as UE 115 or network entity 105) that are capable of harvesting energy from the wireless device's environment, which may be referred to as energy harvesting wireless devices. That is, the energy harvesting wireless device may harvest energy from the environment (such as via the sun, heat, or ambient RF radiation), and may store the energy in an energy storage device (such as a rechargeable battery) of the energy harvesting wireless device (e.g., unlike the backscatter communication-based PIoT where battery-free wireless devices collect energy from ambient RF signals and redirect them like a radio frequency identifier (RFID) tag). In some cases, the energy harvesting wireless device may include RF components (e.g., power consumption) such as one or more analog-to-digital converters (ADCs), one or more mixers, and one or more oscillators.

[0054] In some other cases, the energy harvesting wireless device may support backscatter communications (e.g., in 5G Advanced systems). That is, the energy harvesting wireless device (e.g., a PIoT device) may not be associated with an energy storage device, such that the energy harvesting wireless device may receive an energy transfer signal and transmit an information-carrying signal (e.g., at a certain data rate, power, density, etc.) based on the received energy transfer signal, which may be referred to as a backscatter modulated signal. Such energy harvesting wireless devices may support identification, tracking, authentication, authorization, access control, mobility management, security, and sensing, among other operations.

[0055] Additionally or alternatively, the energy harvesting wireless device may be associated with a constrained energy storage device (e.g., a capacitor). Such energy harvesting wireless devices (e.g., supporting energy harvesting enabled communication services (EHECS) in 5G systems) may support power supply, security, access control, connectivity management, and positioning, among other operations.

[0056] In some cases, an energy harvesting wireless device may intermittently harvest energy based on available energy from the environment (e.g., according to an enhanced protocol). For example, the amount of energy available for the energy harvesting wireless device to harvest from the environment may vary (e.g., the amount of energy that the energy harvesting wireless device can expect to harvest, and changes in traffic). Therefore, an energy harvesting wireless device that intermittently harvests energy based on available energy from the environment may not support continuous transmission and / or reception for a duration greater than a threshold (e.g., may not maintain extended continuous transmission and / or reception).

[0057] In some cases, the wireless communication system 200 may support a wireless device (such as a UE 115 or a network entity 105) that is capable of sending energy in the form of an energy transfer signal, which may be referred to as an energy providing (e.g., power providing) wireless device. For example, the energy providing wireless device may send (e.g., via an uplink or a sidelink) an energy transfer signal to an energy harvesting wireless device, and the energy harvesting wireless device may harvest energy from the energy transfer signal to charge an energy storage device associated with the energy harvesting wireless device. However, conventional techniques may not support power control for the energy providing wireless device and the energy harvesting wireless device, which may result in inefficiencies in the operation of the energy harvesting wireless device, the energy providing wireless device, or both.

[0058] Thus, the techniques described herein may support power control for an energy providing wireless device, such as a UE 115-a, which may be an example of an energy providing UE 115-a. In some cases, the UE 115-a may receive a control message 205-a indicating a set of energy transfer power control schemes from the network entity 105-a, wherein each energy transfer power control scheme specifies how the UE 115-a determines a transmit power level (e.g., transmit power) for an energy transfer signal 215. Additionally, the UE 115-a may receive a control message 205-b activating (e.g., or deactivating) a first energy transfer power control scheme from the set of energy transfer power control schemes. In some cases, activating the first energy transfer power control scheme may be based on one or more carriers associated with the energy transfer signal 215, a bandwidth portion (e.g., a sidelink bandwidth portion, an uplink bandwidth portion, a downlink bandwidth portion) associated with the energy transfer signal 215, a resource pool associated with the energy transfer signal 215, a congestion level, a QoS, or any combination thereof. UE 115-a may send a scheduling message 210 to UE 115-b, which may function as an energy harvesting UE 115-b, scheduling transmission of an energy transfer signal 215. Additionally, UE 115-a may send energy transfer signal 215 at a transmit power level according to a first energy transfer power control scheme.

[0059] In some cases, the first energy transfer power control scheme may indicate that the UE 115-a is to transmit the energy transfer signal 215 at a defined (e.g., constant) transmit power level based on an indication (e.g., a layer 1, layer 2, or layer 3 indication or pre-configuration) received to or from an additional wireless device (e.g., a network entity 105, a CU 160, a UE 115, a programmable logic controller (PLC), an RF power transmit controller) such as the network entity 105-a. For example, the UE 115-a may receive control signaling (e.g., sidelink control information (SCI), MAC control element (MAC-CE), RRC, downlink control information (DCI), or uplink control information (UCI)) associated with the energy transfer signal 215 from the network entity 105-a (e.g., or received before the energy transfer signal 215 is transmitted) indicating the first transmit power level. As a result, the UE 115-a may transmit the energy transfer signal 215 to the UE 115-b at the first transmit power level. In some cases, UE 115-a may send or receive additional control signaling indicating a second (e.g., updated) transmit power level associated with the first energy transfer power control scheme, such that UE 115-a may send additional energy transfer signals 215 (e.g., scheduled via additional scheduling messages 210) at the second transmit power level (e.g., the transmit power level may change dynamically from time to time). In some examples, the transmit power level (e.g., a constant power level) may be based on a power class or power type of UE 115-b (e.g., a wireless device to be charged), a current charging rate (e.g., from RF or other technology) at UE 115-b, a threshold (e.g., required by RF) charging rate of UE 115-b, a charging quality of service (QoS) at UE 115-b, a capacity of an energy storage device at UE 115-b, a discharge rate of UE 115-b, a charging priority associated with UE 115-b, an energy discharge type, or any combination thereof.

[0060] In some cases, the first energy transfer power control scheme may indicate that UE 115-a will transmit at full power to charge one or more UEs. This energy transfer power control scheme may be subject to the type of UE 115-a, the power providing capabilities of UE 115-a, the device power class of UE 115-a, regulatory requirements, or any combination thereof.

[0061] In some cases, the first energy transfer power control scheme may indicate that UE 115-a is to transmit energy transfer signal 215 at a transmit power level based on the power class of UE 115-a, UE 115-b, or both. In some cases, UE 115-a may receive an indication of the power class of UE 115-b from UE 115-b. The power class of UE 115-b may be associated with the charging rate of UE 115-b, the power density at UE 115-b (e.g., when energy transfer signal 215 arrives), the battery state of UE 115-b (e.g., the current battery state), the charging QoS at UE 115-b, and one or more thresholds associated with UE 115-b (e.g., regulatory requirements).

[0062] In some cases, the first energy transfer power control scheme may indicate that the UE 115-a is to transmit the energy transfer signal 215 at a transmit power level based on a path loss (e.g., an open-loop or closed-loop path loss). For example, the UE 115-a may measure a path loss (e.g., open-loop) associated with a communication between the UEs 115-a, between one or more additional wireless devices, or between the two. In some cases, the path loss may be an open-loop power control based on a downlink path loss, an open-loop power control based on an uplink path loss, an open-loop power control based on a sidelink path loss, or any combination thereof. Additionally or alternatively, the path loss may be based on a frequency range associated with the communication, an antenna used to send or receive the communication at the UE 115-a, and the like.

[0063] In some cases, the first energy transfer power control scheme may indicate that UE 115-a is to transmit the energy transfer signal 215 at a transmit power level based on: the charging rate of UE 115-b, the battery status of UE 115-b (e.g., the current battery status), the charging QoS at UE 115-b, the discharge rate of UE 115-b (e.g., due to UE 115-b being active (e.g., turned on), the energy storage unit leaking, or both), the charging priority associated with UE 115-b (e.g., level 1 or level 3 priority), the energy discharge type associated with UE 115-b (e.g., unicast transmission of the energy transfer signal 215 to one UE 115, groupcast transmission of the energy transfer signal 215 to a group of UEs 115, multicast transmission of the energy transfer signal to all UEs 115), or any combination thereof (e.g., to perform closed-loop power control), any of which may be indicated to UE 115-a in capability signaling received from UE 115-b. The energy application type (e.g., unicast, groupcast, broadcast) can be for a single or multiple energy harvesting UEs, and can be signaled to the UEs harvesting energy for a specific application type to change a single parameter, multiple parameters, or all parameters described herein, including, for example, a maximum transmit power level, a fixed transmit power level, a dynamic change from a first transmit power level to a second transmit power level, etc.

[0064] In some examples, UE 115-b may operate at a high discharge rate such that UE 115-a may transmit energy transfer signal 215 at a higher transmit power level (e.g., compared to a low discharge rate) in consideration of the high discharge rate. In some cases, UE 115-b may be associated with a threshold (e.g., minimum or default) discharge rate. In another example, UE 115-b may transmit a request for energy transfer (e.g., to power UE 115-b) to UE 115-a indicating a charging priority and may transmit the energy transfer signal at a transmit power level based on the charging priority. In some cases, the charging priority may be based on a priority associated with a data transmission to be received by UE 115-b (e.g., or being received by UE 115-b) (e.g., UE 115-b is being charged to receive data transmission by UE 115-a or another energy providing device), based on a priority associated with a data transmission to be sent by UE 115-b (e.g., the priority of data buffered at UE 115-b), based on a priority associated with a remaining packet delay budget for packets to be received or sent by UE 115-b (e.g., or both in the case where UE 115-b will use power from energy transfer signal 215 for both reception and transmission), or any combination thereof. In another example, UE 115-a may send an energy transfer signal 215 to a group of UEs 115 (e.g., based on energy disposal associated with groupcast transmissions to the group of UEs 115) such that UE 115-a may send the energy transfer signal 215 at a higher transmit power level (e.g., maximum, fixed, or dynamic) than a transmit power level associated with sending the energy transfer signal 215 to UE 115-b (e.g., based on energy disposal associated with unicast transmissions to a single UE 115).

[0065] In some cases, UE 115-a may receive from UE 115-b an indication of: a charging rate of UE 115-b, a battery status of UE 115-b, a charging QoS at UE 115-b, a discharge rate of UE 115-b, a charging priority associated with UE 115-b, an energy discharge type associated with UE 115-b, or any combination thereof.

[0066] In some cases, the first energy transfer power control scheme may be associated with a lowest transmit power level from a set of transmit power levels associated with a set of energy transfer power control schemes. That is, the first energy transfer power control scheme may be associated with the lowest transmit power level of the aforementioned energy transfer power control schemes. In some examples, the value of the transmit power level for any one of the aforementioned energy transfer power control schemes may be defined, configured, or preconfigured per carrier, per energy-dedicated BWP, per sidelink bandwidth portion, per uplink bandwidth portion, per resource pool, based on congestion level, based on priority, based on quality of service, or any combination thereof.

[0067] Additionally or alternatively, multiple energy providing UEs 115 may coordinate energy transfer signals 215 and transmit these energy transfer signals (e.g., provide power) to a single or multiple energy harvesting UEs 115. For example, UE 115-a may be associated with a group of energy providing UEs 115 that transmit energy transfer signals 215 to UE 115-b. In such cases, the first energy transfer power control scheme activated by the control message 205-b may indicate that each energy providing UE 115 in the group of energy providing UEs 115 may transmit a respective energy transfer signal 215 based on a transmit power level of a path loss (e.g., an uplink path loss, a sidelink path loss, or a downlink path loss). For example, the path loss may be based on a maximum (e.g., highest) path loss measurement from a set of path loss measurements (including path loss measurements performed by each energy providing UE 115 in the group of energy providing UEs 115 (e.g., for a given interface)). For example, as previously described, the UE 115 - a may measure path loss (eg, open loop) associated with communications between the UE 115 - a and one or more additional wireless devices.

[0068] In some cases, the UE 115-a may be a UE 115 that initiated (e.g., started) the transmission of the energy transfer signal 215 (e.g., initiated the energy transfer operation using layer 1, layer 2, or layer 3 signaling). In some other cases, the UE 115-a may be a UE 115 that selected or reserved (e.g., requested the network entity 105 in a mode 1 random access) the energy transfer resources associated with the energy transfer signal 215. In some cases, the UE 115-a may be a UE 115 that first transmitted the energy transfer signal 215. In some other cases, the UE 115-a may be a UE 115 that was instructed via a control message 205-b received from a control unit (e.g., instructed by the CU 160 or the network entity 105 signaling to start the energy transfer operation). In some cases, the UE 115-a may send an indication of a transmit power level based on a path loss to each energy providing UE 115 in a group of energy providing UEs 115 (e.g., via layer 1, layer 2, or layer 3 signaling). Additionally or alternatively, each energy providing UE 115 in the group of energy providing UEs 115 may transmit a respective energy transfer signal 215 at a respective transmit power level relative to a transmit power level based on the indication of the path loss. In some cases, the transmit power level (e.g., a maximum, fixed, or dynamic transmit power) associated with the transmission of the energy transfer signal 215 to one energy harvesting UE 115 may be greater than the transmit power level associated with the transmission of the energy transfer signal 215 to more than one energy harvesting UE 115.

[0069] In some cases, the energy transfer signal 215 may be associated with an energy per resource element (EPRE). In some examples, the EPRE associated with the energy transfer signal 215 may be based on (e.g., defined with respect to at least one of) a control channel (e.g., a physical downlink control channel (PDCCH) or a physical sidelink control channel (PSCCH)) or a data channel (e.g., a physical downlink shared channel (PDSCH), a physical sidelink shared channel (PSSCH), or a physical uplink shared channel (PUSCH)) used by the UE 115-a to send the energy transfer signal 215.

[0070] Additionally or alternatively, an EPRE of a demodulation reference signal (DMRS) associated with the energy transfer signal 215 may be based on (e.g., defined with respect to at least one of) a control channel (e.g., PDCCH or PSCCH) or a data channel (e.g., PDSCH, PSSCH, or PUSCH) used by the UE 115-a to send the energy transfer signal 215. That is, the UE 115-a may simultaneously send the energy transfer signal 215 and the data message such that the UE 115 receiving the data message may eliminate (e.g., remove) the energy transfer signal 215 based on the EPRE of the DMRS. In some cases, the EPRE of the DMRS may be the same as the EPRE of a sidelink reference signal (SL-RS), a PSCCH DMRS, a PDCCH DMRS, a PSSCH DMRS, a PDSCH DMRS, a PUSCH DMRS, or any combination thereof.

[0071] Although much of the present disclosure is described in the context of an energy providing UE 115-a and an energy harvesting UE 115-b, this should not be viewed as a limitation of the present disclosure. In fact, it is contemplated herein that the energy providing wireless device may be the UE 115 and the energy harvesting wireless device may be the UE 115. In this regard, the energy providing wireless device, the energy harvesting wireless device, or both may be the network entity 105.

[0072] Figure 3 An example of a wireless communication system 300 that supports power control for power providers and energy harvesting transmitters according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 300 can implement or be implemented by aspects of the wireless communication system 100 and the wireless communication system 200. For example, the wireless communication system 300 may include one or more network entities 105 (e.g., network entity 105-b) and one or more UEs 115 (e.g., UEs 115-c and 115-d), which may be reference Figure 1 Examples of the corresponding devices described. Figure 3 In the example of FIG. 1 , the network entity 105 - b may be as shown in FIG. Figure 1 The examples of CU 160, DU 165, RU 170, base station 140, IAB node 104, or one or more other network nodes are described. In some cases, UE 115-b, which may be an energy harvesting UE 115-b, may receive a control message 305-b that activates a first data transmit power control scheme in a set of data transmit power control schemes supported by UE 115-c.

[0073] The wireless communication system 300 may support power control for transmission of one or more data messages by an energy harvesting wireless device (such as a UE 115-c, which may be an example of an energy harvesting UE 115-c). In some cases, the UE 115-c may receive a control message 305-a indicating a set of data transmission power control schemes from the network entity 105-b, wherein each data transmission power control scheme specifies how the UE 115-c determines a transmission power level (e.g., a transmission power) for transmission of a data message 315. Additionally, the UE 115-c may receive a control message 305-b that activates (e.g., or deactivates) a first data transmission power control scheme from the set of data transmission power control schemes. In some cases, activating the first data transmission power control scheme may be based on one or more carriers associated with the data message 315, a bandwidth portion (e.g., a sidelink bandwidth portion, an uplink bandwidth portion, a downlink bandwidth portion) associated with the data message 315, a resource pool associated with the data message 315, a congestion level, a QoS, or any combination thereof. UE 115-c may send a scheduling message 310 to UE 115-d scheduling the transmission of data message 315. Additionally, UE 115-c may send data message 315 at a transmit power level according to a first data transmit power control scheme.

[0074] In some cases, the first data transmit power control scheme may indicate that the UE 115-c is to transmit the data message 315 at a defined (e.g., constant) transmit power level based on an indication (e.g., a level 1, level 2, or level 3 indication or pre-configuration) received to or from an additional wireless device (e.g., network entity 105, CU 160, UE 115, PLC, RF power transmit controller) such as network entity 105-b (e.g., to avoid tracking path loss or to avoid performing open-loop power control). For example, the UE 115-c may receive control signaling (e.g., SCI, MAC-CE, RRC, DCI, or UCI) associated with the data message 315 (e.g., or received before the data message 315 is transmitted) from the network entity 105-b indicating the first transmit power level. As a result, the UE 115-c may transmit the data message 315 to the UE 115-d at the first transmit power level. In some cases, the UE 115-c may receive additional control signaling indicating a second (e.g., updated) transmit power level associated with the first data transmit power control scheme, such that the UE 115-c may transmit additional data messages 315 (e.g., scheduled via the additional scheduling message 310) at the second transmit power level (e.g., the transmit power level may change dynamically from time to time). In such cases, the transmit power level (e.g., a constant power level) may be based on a power class or power type of the UE 115-c, a current charging rate (e.g., from RF or other technology) at the UE 115-c, a threshold (e.g., required by RF) charging rate of the UE 115-c, a charging QoS at the UE 115-c, a capacity of an energy storage device at the UE 115-c, a discharge rate of the UE 115-c, a charging priority associated with the UE 115-c, a priority associated with the data message 315, a quality of service associated with data transmission by the UE 115-c, a data placement type, a packet delay budget, or any combination thereof. For example, a defined transmit power level associated with a high charging rate for the UE 115 - c may be greater than a defined transmit power level associated with a low charging rate for the UE 115 - c .

[0075] In some cases, the first data transmission power control scheme may indicate that the UE 115-c is to transmit the data message 315 at a transmit power level (e.g., at a full power level). In some examples, the UE 115-c may transmit at this power based on the power class of the UE 115-c. The power class of the UE 115-c may be associated with the charging rate of the UE 115-c, the power density at the UE 115-c (e.g., when the data message 315 arrives), the battery state of the UE 115-c (e.g., the current battery state), the charging QoS at the UE 115-c, and one or more thresholds associated with the UE 115-c (e.g., regulatory requirements). For example, the UE 115-c may be associated with a high charging rate and may transmit the data message 315 at a higher transmit power level than a transmit power level associated with a low charging rate (e.g., because power may be available more quickly).

[0076] In some cases, the first data transmission power control scheme may indicate that the UE 115-c is to transmit the data message 315 at a transmission power level based on a path loss (e.g., an open-loop or closed-loop path loss). For example, the UE 115-c may measure a path loss (e.g., open-loop) associated with a communication between the UE 115-c and one or more additional wireless devices. In some cases, the path loss may be an open-loop power control based on a downlink path loss, an open-loop power control based on an uplink path loss, an open-loop power control based on a sidelink path loss, or any combination thereof. Additionally or alternatively, the path loss may be based on a frequency range associated with the communication, an antenna used to transmit or receive the communication at the UE 115-c, and the like.

[0077] In some cases, the first data transmission power control scheme may indicate that UE 115-c is to transmit data message 315 at a transmission power level based on: a charging rate of UE 115-c, a battery status of UE 115-c (e.g., a current battery status), a charging QoS at UE 115-c, a discharging rate of UE 115-c, a priority (e.g., a level 1 and / or level 2 priority) associated with the data message 315 (e.g., being transmitted by UE 115-c), a QoS associated with data transmission by UE 115-c, a data placement type (e.g., a unicast transmission to one UE 115, a groupcast transmission to a group of UEs 115, a multicast transmission to all UEs 115), a packet delay budget (e.g., a remaining packet delay budget for the data being transmitted by UE 115-c), or any combination thereof (e.g., to perform closed-loop power control). In one example, the energy discharge type (e.g., unicast, groupcast, broadcast) may be for a single or multiple energy harvesting UEs, and may be signaled to the energy harvesting UEs communicating one or more data messages for a particular discharge type to change a single parameter, multiple parameters, or all parameters described herein, including, for example, a maximum transmit power level, a fixed transmit power level, a dynamic change of a first transmit power level to a second transmit power level, etc. In one example, the UE 115-c may operate at a high discharge rate such that the UE 115-c may transmit the data message 315 at a lower transmit power level (e.g., compared to the low discharge rate) in view of the high discharge rate.

[0078] In some cases, the first data transmit power control scheme may be associated with a lowest transmit power level from a set of transmit power levels associated with the set of data transmit power control schemes. That is, the first data transmit power control scheme may be associated with a lowest transmit power level among the aforementioned transmit power levels.

[0079] Please note that Figure 2 and Figure 3 The discussed techniques may be used together, where an energy transfer power control scheme is used by an energy providing UE to charge an energy harvesting UE, and the energy harvesting UE uses a data transmission power control scheme to determine and use a power control level for sending data messages.

[0080] Although much of the present disclosure is described in the context of an energy harvesting UE 115-c, this should not be viewed as limiting of the present disclosure. Indeed, it is contemplated herein that the energy harvesting wireless device may be a UE 115. In this regard, the energy harvesting wireless device may be a network entity 105.

[0081] Figure 4An example of a process flow 400 for supporting power control for a power provider and an energy harvesting transmitter according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 400 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, and the wireless communication system 300. For example, the process flow 400 may include one or more network entities 105 (e.g., network entity 105-c) and one or more UEs 115 (e.g., UE 115-e and UE 115-f), which may be reference Figure 1 Examples of the corresponding devices described. Figure 4 In the example of FIG. 1 , the network entity 105 - c may be as shown in FIG. Figure 1 The CU 160, DU 165, RU 170, base station 140, IAB node 104, or one or more other network nodes are described as examples. In some cases, the UE 115-e that may be provided with energy 115-e may receive a second control message that activates a first data transmit power control scheme in a set of data transmit power control schemes supported by the UE 115-e.

[0082] At 405, the UE 115-e may receive a first control message indicating a set of energy transfer power control schemes. In some cases, the UE 115-e may receive the first control message from the network entity 105-c. In some other cases, the UE 115-e may receive the first control message from the UE 115-f, which may be an energy harvesting UE 115-f.

[0083] At 410, UE 115-e may receive a second control message indicating activation of a first energy transfer power control scheme in a set of energy transfer power control schemes. In some cases, UE 115-e may receive the second control message from network entity 105-c. In some other cases, UE 115-e may receive the second control message from UE 115-f. Additionally, activating the first energy transfer power control scheme may be based on one or more carriers associated with the energy transfer signal, a bandwidth portion associated with the energy transfer signal (e.g., a sidelink bandwidth portion, an uplink bandwidth portion, a downlink bandwidth portion), a resource pool associated with the energy transfer signal, a congestion level, a quality of service, a priority level, or any combination thereof.

[0084] In some cases, the first energy transfer power control scheme may indicate that the UE 115-e is to transmit at a defined transmit power level according to an indication received from a second wireless device (such as the network entity 105-c or the UE 115-f). For example, the UE 115-e may receive control signaling indicating the first defined transmit power level. Additionally, the UE 115-g may receive additional control signaling indicating a second (e.g., updated) defined transmit power level.

[0085] In some other cases, the first energy transfer power control scheme may indicate that UE 115-e is to transmit energy transfer signals at a transmit power level based at least in part on the power class. In some examples, UE 115-e may receive an indication of the power class from UE 115-f.

[0086] In some cases, the first energy transfer power control scheme may indicate that the UE 115-e is to transmit the energy transfer signal at a transmit power level based at least in part on a path loss, where the path loss is a downlink path loss, a sidelink path loss, or an uplink path loss. In some cases, at 415, the UE 115-e may measure a path loss associated with communications between the UE 115-e and the UE 115-f, where the UE 115-e initiated scheduling of the energy transfer signal, selected or requested energy transfer resources associated with the energy transfer signal, initiated transmission of the energy transfer signal, or was associated with an indication provided in the first control message. In some cases, the UE 115-e may receive an indication of the path loss from the second wireless device.

[0087] In some cases, the first energy transfer power control scheme may be associated with a lowest transmit power level in a set of transmit power levels associated with the set of energy transfer power control schemes.

[0088] In some cases, at 420, UE 115-e may receive a capability message from UE 115-f indicating one or more parameters associated with UE 115-f. For example, UE 115-f may send, to UE 115-e, an indication of a charging rate of UE 115-e, a charging QoS of UE 115-e, a battery status of UE 115-e, a discharge rate of UE 115-e, a charging priority associated with UE 115-e, an energy discharge type, or any combination thereof. In some cases, the transmit power level may be based on the charging rate, the charging quality of service, the battery status, the discharge rate, the charging priority, the energy discharge type, or any combination thereof.

[0089] At 425, UE 115-e may send a scheduling message to UE 115-f to schedule the transmission of the energy transfer signal. Figure 4 As depicted in FIG, 4 , UE 115-f may send a request to UE 115-e to send an energy transfer signal.

[0090] At 430, UE 115-e may send an energy transfer signal to UE 115-f according to the transmit power level of the first energy transfer power control scheme. In some cases, the EPRE associated with the energy transfer signal may be based on a control channel or a shared channel used to send the energy transfer signal. Additionally, the EPRE associated with the energy transfer signal may also be associated with the DMRS.

[0091] In some cases, at 435, the UE 115-f may perform an energy harvesting procedure to charge an energy storage device (such as a rechargeable battery) associated with the UE 115-f. In some cases, the UE 115-f may perform an energy harvesting procedure according to an activated data transmission power control scheme, as described in reference to Figure 5 described.

[0092] Although much of the present disclosure is described in the context of an energy providing UE 115-e and an energy harvesting UE 115-f, this should not be viewed as a limitation of the present disclosure. In fact, it is contemplated herein that the energy providing wireless device may be a UE 115 and the energy harvesting wireless device may be a UE 115. In this regard, the energy providing wireless device, the energy harvesting wireless device, or both may be a network entity 105.

[0093] Figure 5 An example of a process flow 500 for supporting power control for a power provider and an energy harvesting transmitter according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 400 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, and the process flow 400. For example, the process flow 500 may include one or more network entities 105 (e.g., network entity 105-d) and one or more UEs 115 (e.g., UE 115-g and UE 115-h), which may be reference Figure 1 Examples of the corresponding devices described. Figure 5 In the example of FIG. 1 , the network entity 105 - d may be as shown in FIG. Figure 1 The examples of CU 160, DU 165, RU 170, base station 140, IAB node 104, or one or more other network nodes are described. In some cases, UE 115-g, which may be an energy harvesting UE 115-g, may receive a second control message that activates a first data transmit power control scheme in a set of data transmit power control schemes supported by UE 115-g.

[0094] At 505, UE 115-g may receive a first control message indicating a set of data transmission power control schemes. In some cases, UE 115-g may receive the first control message from network entity 105-d. In some other cases, UE 115-g may receive the first control message from UE 115-h.

[0095] At 510, UE 115-g may receive a second control message indicating activation of a first data transmit power control scheme in the set of data transmit power control schemes. In some cases, UE 115-g may receive the second control message from network entity 105-d. In some other cases, UE 115-g may receive the second control message from UE 115-h. Additionally, activating the first data transmit power control scheme may be based on one or more carriers associated with the data message, a bandwidth portion (e.g., a sidelink bandwidth portion, an uplink bandwidth portion, a downlink bandwidth portion) associated with the data message, a resource pool associated with the data message, a congestion level, a quality of service, or any combination thereof.

[0096] In some cases, the first data transmit power control scheme may indicate that the UE 115-g is to transmit at a defined transmit power level according to an indication received from a second wireless device (such as the network entity 105-d or the UE 115-h). For example, the UE 115-g may receive control signaling indicating the first defined transmit power level. Additionally, the UE 115-g may receive additional control signaling indicating a second (e.g., updated) defined transmit power level.

[0097] In some other cases, the first data transmit power control scheme may indicate that the UE 115-g is to transmit data messages at a transmit power level based at least in part on a power class (eg, of the UE 115-g).

[0098] In some cases, the first data transmission power control scheme may indicate that UE 115-g is to transmit the data message at a transmission power level based at least in part on a path loss, where the path loss is a downlink path loss, a sidelink path loss, or an uplink path loss. In some cases, at 515, UE 115-g may measure a path loss associated with communication between UE 115-g and UE 115-h, where UE 115-g initiated scheduling of the data message, selected or requested energy transfer resources associated with the data message, initiated transmission of the data message, or was associated with an indication provided in the first control message. In some cases, UE 115-g may receive an indication of the path loss from a second wireless device.

[0099] In some cases, the first data transmit power control scheme may be associated with a lowest transmit power level in a set of transmit power levels associated with the set of data transmit power control schemes.

[0100] At 520, UE 115-g may send a scheduling message to UE 115-h to schedule the transmission of the data message. Figure 4 ), UE 115-h may send a request to UE 115-g to send a data message.

[0101] At 525 , UE 115 - g may transmit a data message to UE 115 - h according to the transmit power level of the first data transmit power control scheme.

[0102] Although much of the present disclosure is described in the context of an energy providing UE 115-g and an energy harvesting UE 115-h, this should not be viewed as a limitation of the present disclosure. In fact, it is contemplated herein that the energy providing wireless device may be a UE 115 and the energy harvesting wireless device may be a UE 115. In this regard, the energy providing wireless device, the energy harvesting wireless device, or both may be a network entity 105.

[0103] Although much of the present disclosure is described in the context of an energy harvesting UE 115-g, this should not be viewed as limiting of the present disclosure. Indeed, it is contemplated herein that the energy harvesting wireless device may be a UE 115. In this regard, the energy harvesting wireless device may be a network entity 105.
