Technical Field

[0003] The following generally relates to wireless communication, including exceptional resources for energy harvesting devices.

[0004] Background

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and so on. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi-access systems include fourth-generation (4G) systems (such as Long-Term Evolution (LTE) systems, LTE-Advanced (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 multi-access communication system may include one or more base stations, each of which supports wireless communication for communication devices, which may be referred to as user equipment (UE). Summary of the Invention

[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting special resources for energy harvesting devices. For example, the described technology provides support for accessing a pool of "special" resources or a "special" frequency band or sub-band (e.g., a conditional resource pool or a conditional frequency band or sub-band) for use by a wireless device to transmit or receive energy signaling when one or more threshold conditions are met. For example, a first wireless device may receive a control message that indicates a set of conditional energy resources that can be used by the first wireless device to receive energy signaling from a second wireless device or to transmit energy signaling to the second wireless device. Then, based on meeting one or more energy threshold conditions, the first wireless device may receive the energy signaling from the second wireless device or may transmit the energy signaling to the second wireless device. Specifically, the first wireless device may be configured with a set of conditional resource pools or conditional frequency bands or sub-bands and may use these resources to receive energy signals from or transmit energy signals to a second wireless device or a network device. In such examples, these resources may be used when the battery level of the first wireless device or the second wireless device drops below a threshold, when the charging rate of the first wireless device or the second wireless device drops below a threshold, when the first wireless device or the second wireless device would benefit from increased power to transmit high-priority data, and under other conditions.

[0054] In some wireless communication systems, wireless communication devices such as user equipment (UE) may communicate using sidelink communication techniques. For example, a UE may support mode 1 sidelink communication (e.g., where a network entity assigns sidelink resources for the UE to use) or mode 2 sidelink communication (e.g., where the UE autonomously selects sidelink resources for use). However, in some cases, a network entity may configure an additional set or pool of conditional resources (sometimes referred to as "special resources") for a sidelink UE, and when some threshold or special condition is met, the sidelink UE may utilize this additional set or pool of conditional resources. For example, this conditional resource pool may be configured by a network entity for one or more UEs to use when the UE detects a signaling degradation at the physical layer or during a radio link failure. In such cases, the network entity may configure the conditional resource pool such that the UE can access additional resources to maintain continuous service during special situations (e.g., during an emergency or other critical situation). However, in some such conditional situations, the UE may also benefit from access to energy harvesting resources (e.g., if the UE battery level drops below a threshold), such that the UE can receive or transmit energy signaling to improve service reliability and battery life.

[0055] Aspects of the present disclosure may support techniques for accessing a conditional resource pool or conditional frequency band or sub-band (e.g., a special resource pool or frequency band or sub-band) for a UE to send or receive energy signaling when one or more threshold conditions are met. Specifically, a UE may be configured with a set of conditional resource pools (for use in sidelink communication) or conditional frequency bands or sub-bands (for use in direct communication with the network via the Uu link between the network and the UE). In some examples, these conditional frequency bands, sub-bands, or resource pools may be configured for the UE via information transmitted from the network via a master information block (MIB), a system information block (SIB), a control message such as a radio resource control (RRC) configuration message, auxiliary information, or other configuration signaling. Once configured with the conditional resources, the UE may use the resources to receive energy signals from or send energy signals to other UEs or network entities. For example, these resources may be used when the battery level drops below a threshold, when the charging rate of the UE drops below a threshold, or when the UE would benefit from additional power to transmit high-priority data, among other conditions.

[0056] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described by way of and with reference to process flows, apparatus diagrams, system diagrams, and flowcharts related to special resources for energy harvesting devices.

[0057] Figure 1An example of a wireless communication system 100 that supports special resources for an energy harvesting device in accordance with 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 LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies including future systems and radio technologies not explicitly mentioned herein.

[0058] 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 having 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 and other names. In some examples, the network entities 105 and the UEs 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 UEs 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 UEs 115 may support signal communication in accordance with one or more radio access technologies (RATs).

[0059] 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 both stationary and mobile at different times. The UEs 115 may be devices in different forms or having different capabilities. Figure 1 Some example UEs 115 are illustrated. The UEs 115 described herein may be capable of supporting communication with various types of devices such as Figure 1 other UEs 115 or network entities 105 as shown.

[0060] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) can be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, a device, an equipment, 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 can be a UE 115. As another example, the node can be a network entity 105. As yet another example, a first node can be configured to communicate with a second node or a third node. In one aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a UE 115. In another aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a network entity 105. In other aspects of this example, the first node, the second node, and the third node can be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc. can include the disclosure of UE 115, network entity 105, device, equipment, computing system, etc. as nodes. For example, the disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0061] In some examples, network entity 105 can communicate with core network 130 or with each other or both. For example, network entity 105 can communicate with 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, network entity 105 can communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entity 105 can communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. Backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 can be or include one or more wired links (e.g., electrical link, optical fiber link), one or more wireless links (e.g., radio link, wireless optical link), etc. or various combinations thereof. UE 115 can communicate with core network 130 via communication link 155.

[0062] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, Node B, evolved Node B (eNB), next generation Node B or giga Node B (any of which may be referred to as gNB), 5G NB, next generation eNB (ng-eNB), home Node B, home evolved Node B or other suitable terms). In some examples, the network entity 105 (e.g., base station 140) may be implemented in an integrated (e.g., monolithic, stand-alone) base station architecture that 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 base station 140).

[0063] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., disaggregated base station architecture, disaggregated RAN architecture) that may be configured to utilize a protocol stack physically or logically distributed between two or more network entities 105 such as an integrated access backhaul (IAB) network, open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or virtualized RAN (vRAN) (e.g., 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., near real-time RIC (near RT RIC), 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, intelligent radio head, remote radio head (RRH), remote radio unit (RRU), or transmit receive point (TRP). One or more components of the network entity 105 in a disaggregated 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 disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0064] The functional split between the CU 160, DU 165, and RU 170 is flexible and can support different functions, depending on which functions are performed at the CU 160, DU 165, or RU 170 (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof). For example, a functional split of the protocol stack can be employed between the CU 160 and the DU 165 such that the CU 160 can support one or more layers of the protocol stack and the DU 165 can support one or more different layers of the protocol stack. In some examples, the CU 160 can host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., RRC, service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 can be connected to one or more DU 165s or RU 170s, and one or more DU 165s or RU 170s can 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 can each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack can be employed between the DU 165 and the RU 170 such that the DU 165 can support one or more layers of the protocol stack and the RU 170 can support one or more different layers of the protocol stack. The DU 165 can support one or more different cells (e.g., via one or more RU 170s). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 can be within a protocol layer (e.g., some functions of a protocol layer can be performed by one of the CU 160, DU 165, or RU 170, while other functions of that protocol layer are performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 can be further functionally split into a CU control plane (CU-CP) and a CU user plane (CU-UP) function. The CU 160 can be connected to one or more DU 165s via an intermediate transport communication link 162 (e.g., F1, F1-c, F1-u), and the DU 165 can be connected to one or more RU 170s via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the intermediate transport communication link 162 or the fronthaul communication link 168 can be implemented according to the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the respective network entities 105 communicating via such communication links.

[0065] In some wireless communication systems (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections and thereby provide 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 node 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 partially controlled 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 the supported access and backhaul links (e.g., backhaul communication link 120). An IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by the DU 165 of a coupled IAB donor. The IAB-MT may include a separate antenna set for relaying communication with the UE 115 or may share the same antenna (e.g., of an 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 nodes 104, UEs 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the split 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.

[0066] For example, the access network (AN) or RAN may include communication between an access node (e.g., an IAB donor), an IAB node 104, and one or more UEs 115. The IAB donor may facilitate a connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and an RU 170), where the CU 160 may communicate with the core network 130 via an interface (e.g., a fronthaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol that defines signaling messages (e.g., the F1 AP protocol). Additionally or alternatively, the CU 160 may communicate with the core network via an interface (which may be an example of a part of the fronthaul link) and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a part of the fronthaul link).

[0067] The IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UEs 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node towards a child node associated with the IAB node 104, and the IAB-MT may act as a scheduled node towards a parent node associated with the IAB node 104. That is, the IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay transmissions for a UE through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, the IAB node 104 may also be referred to as a parent node or a child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for a child IAB node 104 to receive signaling from a parent IAB node 104, and a DU interface (e.g., the DU 165) may provide a Uu interface for a parent IAB node 104 to signal to a child IAB node 104 or a UE 115.

[0068] For example, the IAB node 104 may be referred to as a parent node supporting communication for a sub-IAB node or as a sub-IAB node associated with an IAB donor or both. The IAB donor may include a CU 160 having a wired or wireless connection to the core network 130 (e.g., a fronthaul communication link 120), and may act as the parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to the UE 115 via the IAB node 104, or may signal transmissions directly to the UE 115, or both. The CU 160 of the IAB donor may signal communication link establishment to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling over the NR Uu interface to the MT of the IAB node 104. Communication with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communication with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104.

[0069] In the case where the techniques described herein are applied in the context of a split RAN architecture, one or more components of the split RAN architecture may be configured to support special resources for an energy harvesting 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 additionally or alternatively be performed by one or more components of the split RAN architecture (e.g., the IAB node 104, the DU 165, the CU 160, the RU 170, the RIC 175, the SMO 180).

[0070] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), multimedia / entertainment device (e.g., radio, MP3 player, or video device), camera, gaming device, navigation / location device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), Beidou system, GLONASS, or Galileo system, ground-based devices, etc.), tablet computer, laptop computer, netbook, smartbook, personal computer, smart device, wearable device (e.g., smartwatch, smart clothing, smart glasses, virtual reality goggles, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), drone, robot / robotic device, vehicle, vehicle device, meter (e.g., parking meter, electricity meter, gas meter, water meter), monitor, air pump, electrical appliance (e.g., kitchen appliance, washing machine, dryer), location tag, medical / health device, implant, sensor / actuator, display, or any other suitable device configured to communicate via a wireless or wired medium. In some examples, the UE 115 may include or may be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances, vehicles, meters, etc.

[0071] The UE 115 described herein may be capable of communicating with various types of devices such as other UE 115s that may sometimes act as relays, as well as network entity 105 and network equipment including macro eNB or gNB, small cell eNB or gNB, or relay base stations, etc., as Figure 1 shown.

[0072] UE 115 and 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 set of RF spectrum resources having a physical layer structure defined to support one or more communication links 125. For example, a carrier for one or more communication links 125 may include a portion (e.g., bandwidth part (BWP)) of an RF spectrum band operating 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 operation, user data, or other signaling. The wireless communication system 100 may support communication with UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, 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 network entity 105 and other devices may refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms "transmit", "receive", or "communicate" when referring to network entity 105 may refer to any part of network entity 105 of the RAN (e.g., base station 140, CU 160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0073] The signal waveform transmitted via a carrier may include multiple sub-carriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing an MCM technique, a resource element may refer to the resource of one symbol period (e.g., the duration of one modulation symbol) and one sub-carrier, where the symbol period and sub-carrier 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 decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., during the transmission duration) and a relatively high order of the 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 layer or beam), and the use of multiple spatial resources may increase the data rate or data integrity for communication with UE 115.

[0074] A time interval for network entity 105 or UE 115 may be expressed as a multiple of a basic time unit, which may refer to, for example, a sampling period seconds, for which may represent the supported subcarrier spacing, while may represent the supported discrete Fourier transform (DFT) size. The time intervals of the communication resources may be organized according to radio frames, each radio frame 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).

[0075] 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 (e.g., in the time domain) into subframes, and each subframe may also be 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 each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., number of) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0076] A subframe, time 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 shortened TTIs (sTTIs)).

[0077] According to various techniques, carriers can be used to multiplex physical channels for communication. For example, one or more of time-division multiplexing (TDM) techniques, frequency-division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels for signaling via a downlink carrier. A control region of a physical control channel (e.g., a control resource set (CORESET)) can be defined by a set of symbol periods and can extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search a control region for control information according to one or more search space sets, and each search space set can 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 can 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 can include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set for transmitting control information to a specific UE 115.

[0078] In some examples, the network entity 105 (e.g., the base station 140, the RU 170) can be movable and thus provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different techniques can overlap, but the different coverage areas 110 can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different techniques can be supported by different network entities 105. The wireless communication system 100 can include, for example, a heterogeneous network in which different types of network entities 105 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0079] Some UEs 115, such as MTC or IoT devices, can be low-cost or low-complexity devices and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or obtain 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 can be designed to collect information or implement automated behavior of machines or other devices. Examples of applications of MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging. In one aspect, the techniques disclosed herein can be applicable to MTC or IoT UEs. MTC or IoT UEs can include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. eMTC and NB-IoT can refer to future technologies that can evolve from or be based on these technologies. For example, eMTC can include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), and mMTC (massive MTC), while NB-IoT can include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT).

[0080] Some UEs 115 can be configured to operate in an operation mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication can be performed at a reduced peak rate. Other energy-saving techniques for UEs 115 include: entering a power-saving deep sleep mode when not participating in active communication, operating using limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 can be configured to operate using a narrowband protocol type 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.

[0081] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). The UE 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication can include private communication or group communication and can be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency can be used interchangeably herein.

[0082] In some examples, the UE 115 can be configured to communicate 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 performing D2D communication in a group can be within the coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), and the network entity can support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group can be outside the coverage area 110 of the network entity 105 or otherwise unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication can support a one-to-many (1:M) system in which each UE 115 transmits to every other UE among the other UEs 115 in the group. In some examples, the network entity 105 can facilitate the scheduling of resources for D2D communication. In some other examples, D2D communication can be performed between UEs 115 without involving the network entity 105.

[0083] 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, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as roadside units) or communicate with the network via vehicle-to-network (V2N) communication via one or more network nodes (e.g., network entity 105, base station 140, RU 170), or both.

[0084] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which can include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions such as the mobility, authentication, and bearer management of the UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets can be passed through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to the IP services 150 of one or more network operators. The IP services 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet switched streaming service.

[0085] The wireless communication system 100 can operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or the decimeter band because, in terms of length, the wavelength range is from approximately one decimeter to one meter. UHF waves can be blocked or redirected by buildings and environmental features (which can be referred to as clusters), but these waves can be sufficient to penetrate structures so that a macro cell can serve a UE 115 located indoors. Compared to communications using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communications using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers).

[0086] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ licensed-assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology that uses unlicensed frequency bands such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating using an unlicensed RF spectrum band, devices such as the network entity 105 and the UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, the operation using an unlicensed frequency band can be based on a carrier aggregation configuration combined with the operation of a component carrier using a licensed frequency band (e.g., LAA). The operation using unlicensed spectrum can include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, etc.

[0087] The network entity 105 (e.g., base station 140, RU 170) or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation 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 at an antenna tower. In some examples, the antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of antenna ports arranged in multiple rows and columns that the network entity 105 may use for beamforming to support communication with the UE 115. Similarly, the UE 115 may include one or more antenna arrays, which may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0088] 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., network entity 105, UE 115) to shape or direct an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via the antenna elements of an antenna array such that some signals propagating in a particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals conveyed via the antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment 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 receiving device or relative to some other direction).

[0089] In some examples, sidelink communication may utilize one or more sidelink configurations or sidelink pre-configurations signaled via a system information block or other control signaling (e.g., using the parameter SL-FreqConfig). In some examples, the sidelink configuration may include Point A parameters, sidelink BWP configuration parameters (SL-BWP-config), sidelink broadcast channel configuration (PSBCH-config), subcarrier spacing parameters (scs-specificcarrier-list), or any combination thereof. In some examples, the sidelink BWP configuration parameters may include a common BWP configuration that includes bandwidth, location, subcarrier spacing, cyclic prefix, and time domain resource information. In some examples, the sidelink BWP configuration parameters may include one or more sidelink resource pool configurations, such as a transmission resource pool for mode 1 sidelink communication, a transmission resource pool for mode 2 sidelink communication, a reception resource pool, or any combination thereof. In some examples, each resource pool configuration may include configurations for PSSCH, PSCCH, and PSFCH, the number of subchannels, subchannel size and starting resource blocks, channel busy rate, modulation and coding scheme, sensing configuration, and power control parameters. In such examples, one BWP may contain multiple reception and transmission resource pools, and physical layer channels may be configured according to the resource pools. In some other examples, the subcarrier spacing parameters may also include a configuration for the bandwidth location associated with the indicated subcarrier spacing.

[0090] The wireless communication system 100 may support different modes of sidelink communication between UEs 115, such as mode 1 sidelink and mode 2 sidelink. In some examples, if the UE 115 is within the coverage of the network entity 105, the UE may support mode 1 or mode 2, and if the UE is outside the coverage of the network entity 105, the UE may support mode 2. In mode 1 sidelink communication, the network entity 105 may schedule or assign sidelink resources for sidelink transmission, where both dynamic allocation via DCI format 3-x and configured transmission (both type 1 and type 2) may be supported. In mode 2 sidelink communication, the UE 115 may autonomously select sidelink resources from a configured set or a pre-configured set of one or more sidelink resource pools based on various factors such as a channel sensing mechanism. For example, the UE 115 may use a channel sensing procedure to identify a set of one or more sidelink resources. Then, based on the result of sensing (e.g., based on the priority of different transmissions and the reference signal received power (RSRP) of different transmissions), the UE 115 may select sidelink resources for sidelink transmission.

[0091] In some examples of the wireless communication system 100, the UE 115 may communicate using sidelink communication. For example, the UE 115 may support mode 1 sidelink communication (e.g., where the network entity 105 assigns resources for the sidelink UE 115 to use) or mode 2 sidelink communication (e.g., where the sidelink UE 115 autonomously selects resources for use). However, in some cases, the network entity 105 may configure a conditional resource pool (also referred to as a special resource set) for the sidelink UE 115, and when some conditions are met, the sidelink UE 115 may utilize or otherwise access the conditional resource pool. For example, the conditional resource pool may be configured for the UE 115 during some time periods and may be used in situations such as when the UE 115 detects a physical layer problem on a link between the UE 115 and the network entity 105 (e.g., the Uu link), on a link between the UE 115 and another sidelink UE, or during various scenarios such as radio link failure. The conditional resource pool may support the availability of additional resources such that the UE can maintain continuous service during special situations (e.g., during an emergency or other critical situation). However, in some such conditional situations, the UE 115 may also benefit from access to energy harvesting resources (e.g., if the battery level of the UE 115 drops below a threshold) to improve service reliability and battery life.

[0092] To support access to energy resources during such special situations, aspects of the present disclosure may describe techniques for introducing a conditional resource pool or conditional frequency band or sub-band (e.g., a conditional resource pool or conditional frequency band or sub-band available during one or more situations) for the UE 115 to use for energy harvesting when some conditions are met or when one or more thresholds are satisfied. Specifically, the UE 115 may be configured with a set of conditional resource pools for use in sidelink communication with another UE 115. Additionally or alternatively, the UE 115 may be configured with one or more conditional frequency bands or sub-bands for use on the Uu link between the network entity 105 and the UE 115. In some examples, these conditional frequency bands, sub-bands, or resource pools may be configured for the UE 115 via information transmitted from the network via control messages, auxiliary information, or other configuration signaling. Once configured with the conditional resources, the UE 115 may use the resources to receive energy signals from other UE 115s or the network entity or to transmit energy signals to other UEs or the network entity. For example, these resources may be used when the battery level of the UE 115 drops below a threshold, when the charging rate of the UE 115 drops below a threshold, or when the UE 115 needs sufficient power to transmit high-priority data, and under other conditions.

[0093] Figure 2Illustrated is an example of a wireless communication system 200 that supports special resources for an energy harvesting device in accordance with one or more aspects of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100 or may be implemented by aspects of the wireless communication system 100. For example, the wireless communication system 200 may include UE 115-a, UE 115-b, and network entity 105-a (each of which may be an example of a corresponding device as described herein). UE 115-a may communicate with network entity 105-a via communication link 125 (e.g., Uu link), and UE 115-a may communicate with UE 115-b on sidelink communication link 210 (e.g., PC5 communication link), which may be an example of one or more communication links 205 as Figure 1 described therein. In this example, UE 115-a and UE 115-b may support sidelink communication.

[0094] In some examples of the wireless communication system 200, UE 115 may be configured with mode 1 sidelink communication (e.g., where network entity 105-a assigns resources for sidelink UE 115 to use) or mode 2 sidelink communication (e.g., where sidelink UE 115 autonomously selects resources for use). In some cases, for mode 1 sidelink communication, network entity 105-a may support assigning resources for sidelink communication and resources for configured transmissions via dynamic allocation via control message 215 (e.g., DCI message). In some other cases, when configured with mode 2 sidelink communication, UE 115 may autonomously select sidelink resources from a preconfigured sidelink resource pool based on a channel sensing process. For example, UE 115-a may identify a configured or preconfigured sidelink resource pool based on the results of a channel sensing process (e.g., based on signal priority and various RSRP measurements), and UE 115-a may select resources from the preconfigured sidelink resource pool for transmission to UE115-b. In some cases, UE 115-a may be located in the coverage area 220 of network entity 105-a and may support both mode 1 sidelink communication and mode 2 sidelink communication. In some examples, UE 115-b may be located outside the coverage area 220 and may support mode 2 sidelink communication. Thus, UE 115-a may be a synchronization reference UE (e.g., syncRef) for sidelink communication with UE 115-b, such that UE 115-a may receive transmissions (e.g., synchronization information) or control messages (e.g., such as control message 215) from network entity 105-a, and UE 115-a may share the transmission or the control message with UE115-b via sidelink communication link 210.

[0095] In some examples, network entity 105-a may configure a "special" or conditional resource pool 225 via a control message 215 (e.g., a System Information Block (SIB) or an RRC message) for use by UE 115 in "special" or conditional situations. For example, when UE 115-a detects a physical layer problem on communication link 205, e.g., during a radio link failure or during other special situations, UE 115-a may use conditional resource pool 225 to maintain continuous service (e.g., during an emergency or other critical situation). In some examples, UE 115 may use conditional resource pool 225 before UE 115 (e.g., UE 115-a or UE 115-b) performs an initiated connection establishment or re-establishment (e.g., a connection establishment such as between network entity 105-a and UE 115-a). In some other examples, UE 115 may use conditional resource pool 225 during a handover procedure. For example, in some cases, UE 115 (such as UE 115-b) may not be configured with mode 1 sidelink communication. Thus, during a handover procedure, if the sensing result for the transmission resource pool is not available, UE 115-b may use conditional resource pool 225 (e.g., the resource pool for regular transmission outside of conditional situations). In some other examples, UE 115 may be in RRC idle mode or RRC inactive mode, and UE 115 may use conditional resource pool 225 during a cell reselection operation before receiving the sensing result of the target cell. In some cases, when initiating a transition from RRC inactive to RRC connected mode and no transmission resource pool is configured, UE 115 may use conditional resource pool 225 to maintain continuous service. In some other cases, network entity 105-a may reconfigure the transmission resource pool for UE 115 via control message 215, so that UE 115 may not be able to access the transmission resource pool. In such a case, UE 115 may use conditional resource pool 225 while monitoring control message 215 indicating the reconfiguration of the transmission resource pool.

[0096] In some examples, the UE 115 (e.g., such as UE 115-a or UE 115-b) may use the conditional resource pool 225 when the UE 115 does not have a stable or reliable configuration of the transmission resource pool and if the UE 115 cannot be removed from the wireless communication system 200 (e.g., the UE 115 is critical to the wireless communication system 200). In some such examples, the UE 115 may use the conditional resource pool 225 by randomly selecting resources for temporary use from the conditional resource pool 225 (e.g., via the serving cell configuration of SIB 21 or in dedicated signaling). In some cases, the UE 115-a may switch to using the conditional resource pool 225 without sending any indication to the UE 115-b, and the UE 115 may continuously monitor the conditional resource pool 225 for physical sidelink control channel (PSCCH) transmissions. This use of the conditional resource pool 225 may support, for example, improved service continuity for public safety UEs 115 or other highly important UEs 115 that rely on service continuity. In some other examples, the UE 115 may have conditional scenarios that require access to energy harvesting resources. For example, the UE 115-a may drop below a battery power threshold and may benefit from access to energy harvesting resources to improve service reliability and battery life.

[0097] To support such improved service and power reliability, when one or more conditions are met, the UE 115 may support using the conditional resource pool 225 or the conditional (sub)band 230 for energy harvesting (e.g., energy signaling) between wireless devices. The conditional (sub)band 230 may be configured for the communication link 205 between the network entity 105-a and the UE 115-a. In some examples, the network entity 105-a may configure the conditional resource pool 225 and the conditional (sub)band 230 for the UE 115 via the control message 215. In some cases, the control message 215 may configure the UE 115 using unicast assistance information, layer 1 (L1) indication, layer 2 (L2) indication, layer 3 (L3) indication, broadcast or multicast (e.g., multicast) signaling via the MIB, SIB 1, various random access messages (e.g., msg2, msg4, or both), or different SIBs, RRC configurations. In such examples, the control message may include an assistance message or an indication of one or more frequency bands, subbands, or resource pools that can be used by the UE 115.

[0098] Additionally or alternatively, the techniques described herein may allow the conditional resource pool 225 to be used for both transmission resources (e.g., transmitting energy signaling) and reception resources (e.g., receiving energy signaling). In some examples, there may be a conditional resource pool 225 for data transmission, data reception, energy signaling transmission, energy signaling reception, or a combination thereof. Additionally, the conditional resource pool 225 for energy reception and the conditional resource pool 225 for energy transmission may be different from the conditional resource pool 225 for sidelink communication between UE 115-a and UE 115-b.

[0099] When configured by network entity 105-a, UE 115-a and UE 115-b may use the conditional resource pool 225 or the conditional (sub)band 230 to improve the service reliability and battery life of UE 115 in some "special" or conditional situations. Examples of situations or conditions in which the conditional resource pool 225 or the conditional (sub)band 230 may be used by UE 115 for energy harvesting are further described herein (including with reference to Figure 3 ).

[0100] Figure 3 An example of a process flow 300 supporting special resources for an energy harvesting device in accordance with one or more aspects of the present disclosure is illustrated. For example, the process flow 300 may include UE 115-c and network entity 105, which may be examples of the corresponding devices described herein. For example, UE 115-c may communicate with the network entity over the Uu link and may communicate with another UE 115 over a sidelink communication link (e.g., a PC5 communication link), which may be an example of the communication link described with reference to Figure 1 and Figure 2 .

[0101] In some examples, UE 115-c may be an example of an energy harvesting UE 115 (e.g., a UE that receives energy signaling from one or more other wireless devices) or a power providing UE 115 (e.g., a UE that transmits or provides energy signaling to one or more other wireless devices). In some examples, UE 115-c may be configured with the conditional resource pool and the conditional (sub)band described with reference to Figure 2 . In some examples, the conditional resource pool and the conditional (sub)band may be examples of the conditional resource pool 225 and the conditional (sub)band 230 described with reference to Figure 2 .

[0102] The process flow 300 can illustrate various conditions where the UE 115-c can receive energy from the power-providing UE 115, send energy to the energy-harvesting UE 115, send signaling to the power-providing UE 115 (e.g., to indicate to the power-providing UE 115 or the network entity 105) to request assistance for an energy or power issue, indicate that the UE 115-c can use a conditional resource pool (and which resources) based on satisfied conditions, or any combination thereof. These conditions can be "special" or conditional situations where the UE 115-c may not be able to use a resource pool with a different configuration for sending or receiving energy signaling (e.g., a resource pool for energy transfer in non-conditional situations), and instead may require access to conditional resources (e.g., a conditional resource pool or a conditional (sub)band) to support improved service reliability and battery life of the UE 115-c.

[0103] In some cases, the UE 115-c can be the energy-harvesting UE 115 and can send an indication of the state of the UE 115-c to the power-providing UE 115. In some other cases, the UE 115-c can be the power-providing UE 115 and can receive a transmission from the energy-harvesting UE 115 indicating the state of the energy-harvesting UE 115.

[0104] At 305, the UE 115-c can detect that the energy level of the UE 115-c may be below a threshold. For example, the UE 115-c can detect that the Uu energy harvesting level on the Uu link is below the threshold, or there is a radio link failure on the Uu link between the UE 115-c and the network entity 105. In some other examples, the UE 115-c can detect that the battery charge of the UE 115-c or the charging rate of the UE 115-c is below the threshold.

[0105] At 310, the UE 115-c may determine that one or more conditions have been met to use or monitor conditional resources for energy harvesting transmission or for energy signaling reception. For example, the UE 115-c may determine that the battery level or charging rate detected at 305 is below a given threshold, such as a battery percentage or charging rate threshold. In some such cases, once the first battery percentage or charging rate drops below the first threshold, the UE 115-c may access the first resource pool, and once its battery percentage or charging rate drops below the second threshold, the UE may access the second resource pool. In some other examples, the UE 115-c may not be configured with dedicated sidelink harvesting with known periodic resources (e.g., mode 1 sidelink communication). In some such examples, at 310, the UE 115-c may detect a drop in energy or charging rate over a time duration of a time window, and the UE 115-c may compare the drop in energy or charging rate with a threshold for the time window. In an example where the drop in energy or charging rate may be higher than the threshold for the time window, the condition to use the conditional resource pool may be met, and the UE 115-c may access the conditional resource pool.

[0106] In some other examples, the UE 115-c may receive an indication that the number of power providing UEs 115 (e.g., energy peer UEs 115) that are using the standard or primary resource pool for energy transmission is below a threshold. Thus, using the standard resource pool may be less efficient than using the conditional resource pool, and thus the UE 115-c may use the conditional resource pool to support improved energy transmission for the UE 115-c. Additionally or alternatively, the UE 115-c may receive a signaling that the number of power providing UEs 115 in the conditional resource pool that are capable of being used for energy transmission is above a threshold, and the UE 115-c may access the conditional resource pool to receive energy from the power providing UEs.

[0107] In some other cases, the UE 115-c may receive an emergency or high-priority data request, such as an ultra-reliable low-latency communication (URLLC) data request, from another UE 115 or network entity 105. In such a case, if the battery state or charging rate of the UE 115-c is below a threshold at a given time of the request, the UE 115-c may access the conditional resource pool to receive energy signaling so that the UE 115-c has sufficient power to send the emergency / high-priority request (which may consume a large amount of power from the UE 115-c). For example, the battery level and charging rate of the UE 115-c may be below a threshold (e.g., the charging rate may not be able to charge the UE 115-c fast enough to support the power consumption of the data request), and a flag may be triggered to use the conditional resources to charge the UE 115-c in preparation for the emergency / high-priority data request.

[0108] In some other examples, UE 115-c may access a conditional resource pool based on a predicted energy state or a predicted change over time of the energy characteristics of UE 115-c. For example, the energy characteristics of UE 115-c may include the current energy state and the predicted energy state over one or more time durations. If the energy state prediction is below an energy state threshold, UE 115-c may access the conditional resource pool to receive energy signaling. The energy characteristics of UE 115-c may also include the current charging rate and the predicted charging rate over one or more time durations. UE 115-c may predict a future discharge rate based on the current discharge rate or power consumption, and if the predicted discharge rate is higher than a threshold discharge rate, UE 115-c may access the conditional resource pool for receiving energy signaling. In some examples, UE 115-c may use one or more energy harvesting techniques (e.g., radio frequency, solar, thermal, or other techniques) to measure the current charging rate and predict the future charging rate. The energy characteristics of UE 115-c may also include the current discharge rate and the predicted discharge rate over one or more time durations. For example, UE 115-c may predict a future discharge rate based on the current discharge rate, or power consumption due to battery leakage or storage unit leakage, scheduling of uplink, downlink, or sidelink communication, or monitoring power parameters.

[0109] In some examples, UE 115-c may input one or more current or estimated parameters into a function, table (e.g., via L1 / L2 / L3), machine learning (ML) model, mapping function, or may use other techniques to determine which resource pools to utilize. In some examples, UE 115-c may periodically select or reselect different resource pools based on these techniques. For example, UE 115-c may determine which resource pools to use and the chronological order of using the resource pools. In examples where UE 115-c determines different times to use different resource pools, UE 115-c may update the timing based on various L1 / L2 / L3 parameters or based on meeting threshold conditions (e.g., threshold priority, threshold number of energy sources in current resources or special resources, threshold battery power or link power, other threshold conditions).

[0110] In some other examples, UE 115-c may receive signaling from a network entity that indicates to UE 115-c one or more conditional resources or subbands that are available for UE 115-c to use. Additionally or alternatively, the network entity may indicate an ordering or sequence of the conditional resource pool or subbands, and UE 115-c may use that ordering or sequence when determining which conditional resource pool or subband to access.

[0111] In such examples, the conditions for using conditional resources may be satisfied by the energy harvesting UE 115 and may be detected by the energy harvesting UE 115 or another power providing UE 115. In the case where UE 115-c may be the energy harvesting UE 115, UE 115-c may detect that the conditions for using or monitoring the conditional resources may be satisfied based at least on the current state of UE 115-c at 305. In the case where UE 115-c may be the power providing UE 115, UE 115-c may detect that the conditions for using or monitoring the conditional resource pool have been satisfied based at least on an indication sent of the state of the energy harvesting UE 115 at 305. For example, the power providing UE 115 may receive a message from the energy harvesting UE or from a network entity that notifies the power providing UE 115 of the requested energy signaling.

[0112] At 315, UE 115-c may send or receive energy signaling via the conditional resources. In the case where UE 115-c may be the energy harvesting UE 115, when the criteria or threshold conditions are satisfied at 310, UE 115-c may use the conditional resources to receive or request energy from the power providing UE 115. In the case where UE 115-c may be the power providing UE 115, UE 115-c may send energy signaling to the energy harvesting UE 115 or receive a request to send energy signaling via the conditional resources.

[0113] At 320, in the case where UE 115-c may be the energy harvesting UE 115, UE 115-c may have received energy signaling from the power providing UE 115. For example, if at 305 UE 115-c detects that the battery level or charging rate is below a threshold, then after receiving energy at 315, at 320, the battery level or charging rate of UE 115-c may be at or above the threshold.

[0114] The techniques described herein may support UE 115 in terms of improved service reliability and battery life. For example, UE115-c may use the conditional resources in the "special" or conditional situations described herein, which may allow enhanced use of the transmission resource pool for sidelink communication between UEs 115 and for communication on the Uu link between UE 115 and network entity 105. Additional conditional situations and the use of conditional resources may be described herein (including references Figure 4 )

[0115] Figure 4An example of a process flow 400 that supports special resources for an energy harvesting device in accordance with one or more aspects of the present disclosure is illustrated. In some examples, the process flow 400 may implement aspects of the wireless communication system 100 or 200, or may be implemented by aspects of the wireless communication system 100 or 200. For example, the process flow 400 may include UE 115-d, UE 115-e, and network entity 105-b, which may be examples of the corresponding devices described herein. In some examples, the first wireless device and the second wireless device may be examples of UE 115 herein, where the first wireless device and the second wireless device may be examples of UE 115-d or UE 115-c. Alternative examples of the following process flow may be implemented, where some 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 additional steps may be added.

[0116] At 405, the network entity 105-b may configure a set of conditional resources to be available for sending energy signaling to one or more wireless devices (e.g., such as UE 115-d and UE 115-e), receiving energy signaling between one or more wireless devices, or both, based on meeting one or more energy threshold conditions. In some cases, the set of conditional energy resources may include a set of one or more subbands, one or more resource pools, and be available for use by a first wireless device (e.g., UE 115-d) and a second wireless device (e.g., UE 115-e). At 410, the network entity 105-b may detect that one or more energy conditions have been met at one or more wireless devices.

[0117] At 415, the network entity 105-b may send a control message to one or more wireless devices (e.g., UE 115-d and UE 115-e) indicating that the set of conditional energy resources is available for use. The first wireless device (e.g., UE 115-d) may receive the control message from the network entity 105-b indicating that the set of conditional energy resources is available for receiving energy transmitted from the second wireless device (e.g., UE 115-e) based on one or more energy threshold conditions.

[0118] In some cases, the first wireless device may receive an indication of the ordering of one or more conditional energy resources within the set of conditional energy resources that are available for the first wireless device. Additionally or alternatively, at 415, the first wireless device may also receive an instruction message indicating that the first wireless device is to use the set of conditional energy resources.

[0119] In some examples, control messages received by a first wireless device (e.g., UE 115-d) and a second wireless device (UE 115-e) from network entity 105-b may include a Master Information Block (MIB), System Information Block (SIB), Radio Resource Control (RRC) messages, and auxiliary information messages, layer indication messages, or any combination thereof. In some other examples, the control messages may include unicast configuration messages, broadcast configuration messages, multicast configuration messages, or any combination thereof. In some cases, a set of conditional energy resources that can be used by the first wireless device to receive energy signaling from the second wireless device may be different from a second set of one or more resources that can be used by the first wireless device. In some examples, the second set of one or more resources may be used by the first wireless device to receive data messages, control messages, or both from the second wireless device.

[0120] At 420, the first wireless device, the second wireless device, or both may detect that one or more energy threshold conditions have been met. At least based on the one or more energy thresholds being met at the first wireless device, the second wireless device, or both, the first wireless device may receive energy signaling from the second wireless device via the set of conditional energy resources at 425. In some cases, at 425, the first wireless device may receive energy signaling via the set of conditional energy resources based on the ordering of the set of conditional resources received at 415. Additionally or alternatively, the ordering may indicate the availability of one or more of the conditional energy resources in the set of conditional energy resources.

[0121] In some examples, based on the one or more energy threshold conditions being met at 420, at 425, the first wireless device may receive energy signaling from the second wireless device via a set of one or more resource pools, a set of one or more subbands, or both. In some cases, the selection of the one or more resource pools, the one or more subbands, or both may be based on the one or more energy threshold conditions being met at 420.

[0122] In some cases, the one or more energy threshold conditions being met at 420 may include an energy threshold associated with a communication link between the first wireless device (e.g., UE 115-d) and network entity 105-b. Thus, at 425, the first wireless device may receive energy signaling from the second wireless device based at least on the energy threshold associated with the communication link being below a threshold, a radio link failure on the communication link, or both.

[0123] In some examples, one or more energy threshold conditions satisfied at 420 may include a battery charge threshold, a charging rate threshold, or both at the first wireless device. In some cases, at 425, the first wireless device may receive energy signaling from the second wireless device via the conditional energy resource set based at least on an indication received by the second wireless device from the first wireless device that the battery charge of the first wireless device may be below the battery charge threshold, the charging rate of the first wireless device may be below the charging rate threshold, or both. In some other examples, one or more energy threshold conditions satisfied at 420 may include a threshold charging rate of the first wireless device over a period of time. In some cases, the first wireless device may estimate a future charging rate based on the current charging rate of the first wireless device and, at 425, receive energy signaling via the conditional energy resource set based on the estimated future charging rate of the first wireless device being less than the threshold charging rate. In some other examples, one or more energy thresholds as conditions satisfied at 420 may include a threshold power consumption rate of the first wireless device over a period of time. In some examples, the first wireless device may estimate a future power consumption rate based at least on the current power consumption rate and, at 425, receive energy signaling via the conditional energy resource set based at least on the estimated power consumption rate of the first wireless device being less than the threshold power consumption rate.

[0124] In such examples, one or more energy thresholds satisfied at 420 may include a battery charge threshold, a charging rate threshold, a power consumption threshold, or any combination thereof. In some cases, the first wireless device may receive a message requesting to send one or more high-priority data messages to be sent from the first wireless device to the second wireless device. Additionally or alternatively, the second wireless device may receive a message indicating that the first wireless device has one or more high-priority data messages to send. Thus, at 425, the first wireless device may receive energy signaling from the second wireless device via the conditional resource set based at least on the battery charge of the first wireless device being below the battery threshold, the charging rate of the second wireless device being below the charging rate threshold, the power consumption of the second wireless device being greater than the power consumption threshold, or any combination thereof. Additionally, at 425, the first wireless device may send one or more high-priority messages based at least on receiving the energy signaling from the second wireless device.

[0125] In some particular implementations, one or more energy thresholds satisfied at 420 may include a threshold number of energy-providing wireless devices (e.g., UE 115) associated with a second set of energy resources. In some cases, at 425, based on the number of energy-providing wireless devices associated with the second set of energy resources being lower than the threshold number of energy-providing wireless devices, the first wireless device may receive energy signaling from the second wireless device via the set of conditional energy resources. In some other particular implementations, one or more energy thresholds satisfied at 420 may include a threshold number of energy-providing wireless devices associated with the set of conditional energy resources.

[0270] It should be noted that the methods described herein describe possible specific implementations, and the operations and steps may be rearranged or otherwise modified and other specific implementations are also possible. Additionally, aspects from two or more methods may be combined.

[0271] A wireless network (e.g., a wireless local area network (WLAN), such as a Wi-Fi (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network) can include access points (APs) that can communicate with one or more wireless or mobile devices. The AP can be coupled to a network such as the Internet and can enable mobile devices to communicate via the network (or communicate with other devices coupled to the access point). Wireless devices can communicate bidirectionally with network devices. For example, in a WLAN, a device can communicate with an associated AP via a downlink (e.g., a communication link from the AP to the device) and an uplink (e.g., a communication link from the device to the AP). A wireless personal area network (PAN) (which can include a Bluetooth connection) can provide a short-range wireless connection between two or more paired wireless devices. For example, a wireless device (such as a cellular phone) can utilize wireless PAN communication to exchange information such as audio signals with a wireless headset. Components within a wireless communication system can be coupled to each other (e.g., operatively coupled, communicatively coupled, functionally coupled, electronically coupled, and / or electrically coupled).

[0272] Although aspects of LTE, LTE-A, LTE-A Pro, or NR systems may be described for example purposes and the terms LTE, LTE-A, LTE-A Pro, or NR may be used in much of the description, the techniques described herein may also apply to networks other than LTE, LTE-A, LTE-A Pro, or NR networks. For example, the described techniques can apply to a variety of other wireless communication systems such as Ultra Mobile Broadband (UMB), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, and other systems and radio technologies not explicitly mentioned herein, including future systems and radio technologies.

[0273] The information and signals described herein can be represented using any of a variety of different technologies and methods. For example, data, instructions, commands, information, signals, bits, symbols, and chips referred to throughout the specification can be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof.

[0274] The various illustrative block boxes and components described in connection with the present disclosure can be implemented or performed using a general-purpose processor, a DSP, an ASIC, a CPU, a GPU, an FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof that is designed to perform the functions described herein. The general-purpose processor may be a microprocessor, but in the alternative, the processor may be any processor, controller, microcontroller, or state machine. At least one processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0275] The functions described herein can be implemented in hardware, software executed by at least one processor, or a combination of both. Software should be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, execution threads, procedures, or functions, whether described in terms of software, firmware, middleware, microcode, hardware description language, or other terms. When implemented in software executed by at least one processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of the present disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software, firmware, hardwired, or any combination thereof executed by at least one processor. The features implementing the functions may also be physically located at different positions, including being distributed such that various parts of the functions are implemented at different physical locations.

[0276] A computer-readable medium includes both a non-transitory computer storage medium and a communication medium including any medium that facilitates transfer of a computer program from one location to another. A non-transitory storage medium may be any available medium that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, phase change memory, compact disc read only memory (CD-ROM) or other optical disc storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures and that can be accessed by a general purpose or special purpose computer or a general purpose or special purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of computer-readable medium. As used herein, disk and disc include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc. Disk may reproduce data magnetically, while disc may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable medium.

[0277] As used herein (including in the claims), the "or" used in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") indicates an inclusive listing such that, for example, the listing of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Additionally, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" may be based on both condition A and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on". As used herein, when the term "and / or" is used in a list of two or more items, it means that any one of the listed items can be taken alone, or any combination of two or more of the listed items can be taken. For example, if a composition is described as including components A, B, and / or C, the composition can include A alone; B alone; C alone; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B, and C.

[0278] The terms "determine" or "identify" cover a variety of actions, and thus, "determine" or "identify" can include calculus, computation, processing, derivation, investigation, lookup (such as looking up via a table, database, or another data structure), ascertainment, etc. Additionally, "determine" or "identify" can include receiving (such as receiving information or signaling, e.g., receiving information or signaling for determination, receiving information or signaling for identification), accessing (such as accessing data in a memory or accessing information), etc. Additionally, "determine" or "identify" can include parsing, obtaining, selecting, picking, establishing, and other such similar actions.

[0279] In the figures, similar components or features may have the same reference numeral. Additionally, various components of the same type can be distinguished by adding a dash and a second numeral used to differentiate between similar components after the reference numeral. If only the first reference numeral is used in the specification, the description can apply to any one of the similar components having the same first reference numeral, regardless of the second reference numeral or any other subsequent reference numerals.

[0280] The description set forth herein in connection with the figures describes example configurations and does not represent all examples that can be implemented or are within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration" and not "preferred" or "advantageous over other examples". The detailed description includes specific details for providing an understanding of the described techniques. However, the techniques can be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0281] The present description is provided to enable a person of ordinary skill in the art to make or use the present disclosure. Various modifications to the present disclosure are apparent to a person of ordinary skill in the art, and the general principles defined herein can be applied to other variations without departing from the scope of the present disclosure. Thus, the present disclosure is not limited to the examples and designs described herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
