SCHEDULING AND RESOURCE ALLOCATION FOR ENERGY-HARVESTING CAPABLE DEVICES
[0001] FIELD OF TECHNOLOGY
[0002] The present disclosure relates to wireless communications, including scheduling and resource allocation for energy-harvesting capable devices.BACKGROUND
[0003] Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the 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, 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 technologies 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 communications system may include one or more base stations, each supporting wireless communication for communication devices, which may be known as user equipment (UE) .SUMMARY
[0004] The described techniques relate to improved methods, systems, devices, and apparatuses that support scheduling and resource allocation for energy-harvesting (EH) -capable devices. EH-capable devices such as ambient internet of things (AIoT) devices may be used for applications such as inventory tracking, sensing, positioning, or command systems. EH-capable devices may include multiple functions stored in memory. An interrogating device may transmit a modify command (e.g., a write command) to an EH-capable device that modifies two or more functions, where the functions are stored in discontinuous memory locations in the EH-capable device. In some examples, the modify command may indicate (e.g., via bits corresponding to the memory bank of the EH-capable device) which functions will be written / modified. In some examples, the initial request may indicate the functions or memory locations that will be written, which may reduce the size of the modify command. Additionally, or alternatively, a new deactivate command may be introduced to deactivate an EH-capable device for an indicated or predetermined amount of time.
[0005] A method for wireless communications by an EH-capable device is described. The method may include receiving a control message that indicates a request to transmit a modify command to the EH-capable device, the modify command associated with modifying two or more functions stored in discontinuous memory locations of the EH-capable device, transmitting an acknowledgment in response to the control message, the acknowledgment indicating that transmission of the modify command is permitted for modifying the two or more functions, and receiving, based on the acknowledgment, the modify command for the two or more functions of the EH-capable device stored in the discontinuous memory locations of the EH-capable device.

[0042] Some wireless communications systems may support deployment of ambient internet of things (AIoT) devices, which may include relatively low power and low complexity devices that are capable of harvesting energy from different sources, such as radio frequency waves, solar energy, heat, or other ambient sources. Energy harvesting (EH) -capable devices such as AIoT devices may be used for applications such as inventory tracking, sensing, positioning, or command systems. For example, for command systems, EH-capable devices may be used for such applications as control of irrigations systems, dispensing medicine, or providing alerts. An EH-capable device may perform a backscatter based communication (e.g., transmit data) via backscattering an interrogating signal received from another wireless communications device (e.g., a reader device) . The term “interrogating signal” may refer to a signal received at an EH-capable device from another wireless communications device which provides energy for the EH-capable device to transmit a signal, for example, via backscatter modulation.
[0043] EH-capable devices may include multiple functions stored in memory. An interrogating device may issue a write command to modify a portion of memory or an erase command to erase a portion of memory of the EH-capable device. To initiate a write or erase command, the interrogator may transmit a request for a random number. The EH-capable device may transmit an acknowledgment that includes a random number, and the write or erase command may include the random number as a security check. Some EH-capable devices may include multiple functions stored in memory, and a single write or erase command may not be capable of modifying more than one but less than all of the functions when the functions are stored in discontinuous memory locations in the EH-capable device. Further, an interrogating device may issue a “kill” command to permanently disable an EH-capable device, but currently there is no command to temporarily deactivate an EH-capable device.
[0044] An interrogating device may transmit a modify command (e.g., a write command) to an EH-capable device that modifies two or more functions, where the functions are stored in discontinuous memory locations in the EH-capable device. In some examples, the modify command may indicate (e.g., via bits corresponding to the memory bank of the EH-capable device) which functions will be written / modified. In some examples, the initial request may indicate the functions or memory locations that will be written, which may reduce the size of the modify command. In some examples, the initial request may indicate the resources (e.g., time and / or frequency resources) for the EH-capable device to transmit the acknowledgment to the request. Indicating which functions may be written in the request (e.g., a downlink control information (DCI) like control message) may reduce the size of the modify command and thereby reduce power consumption at the EH-capable device. Additionally, or alternatively, a new deactivate command may be introduced to deactivate an EH-capable device for an indicated or predetermined amount of time.
[0045] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to signaling timing diagrams, timing diagrams, process flows, apparatus diagrams, system diagrams, and flowcharts that relate to scheduling and resource allocation for energy-harvesting capable devices.
[0046] FIG. 1 shows an example of a wireless communications system 100 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications 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.
[0047] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0048] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0049] As described herein, a node of the wireless communications 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, a node may be a UE 115. As another example, a 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 yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0050] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0051] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0052] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and 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, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an 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) system, such as an SMO system 180, or any combination thereof. An 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 transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0053] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both 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 a DU 165 and an 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 multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0054] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0055] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support test 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., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0056] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A 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, a UE 115 may include or 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 communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0057] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0058] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0059] In some examples, such as in a carrier aggregation configuration, a carrier may have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radio access (E-UTRA) absolute RF channel number (EARFCN) ) and may be identified according to a channel raster for discovery by the UEs 115. A carrier may be operated in a standalone mode, in which case initial acquisition and connection may be conducted by the UEs 115 via the carrier, or the carrier may be operated in a non-standalone mode, in which case a connection is anchored using a different carrier (e.g., of the same or a different RAT) .
[0060] The communication link (s) 125 of the wireless communications system 100 may include downlink transmissions (e.g., forward link transmissions) from a network entity 105 to a UE 115, uplink transmissions (e.g., return link transmissions) from a UE 115 to a network entity 105, or both, among other configurations of transmissions. Carriers may carry downlink or uplink communications (e.g., in an FDD mode) or may be configured to carry downlink and uplink communications (e.g., in a TDD mode) .
[0061] 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 the wireless communications system 100. For example, the carrier bandwidth may be one of a set of bandwidths for carriers of a particular RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz) ) . Devices of the wireless communications system 100 (e.g., the network entities 105, the UEs 115, or both) may have hardware configurations that support communications using a particular carrier bandwidth or may be configurable to support communications using one of a set of carrier bandwidths. In some examples, the wireless communications system 100 may include network entities 105 or UEs 115 that support concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured for operating using portions (e.g., a sub-band, a BWP) or all of a carrier bandwidth.
[0062] Signal waveforms transmitted via a carrier may be made up 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 employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity 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) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0063] One or more numerologies for a carrier may be supported, and a numerology may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs having the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time and communications for the UE 115 may be restricted to one or more active BWPs.
[0064] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource 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) .
[0065] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or 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 be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0066] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0067] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0068] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT) , enhanced mobile broadband (eMBB) ) that may provide access for different types of devices.
[0069] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0070] Some UEs 115, such as MTC or IoT devices, may be relatively low cost or low complexity devices and may provide for automated communication between machines (e.g., via Machine-to-Machine (M2M) communication) . M2M communication or MTC may refer to data communication technologies that allow devices to communicate with one another or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application program that uses the information or presents the information to humans interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for 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.
[0071] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communications (e.g., a mode that supports one-way communication via transmission or reception, but not transmission and reception concurrently) . In some examples, half-duplex communications may be performed at a reduced peak rate. Other power conservation techniques for the UEs 115 may include entering a power saving deep sleep mode when not engaging in active communications, operating using a limited bandwidth (e.g., according to narrowband communications) , or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type that is associated with a defined portion or range (e.g., set of subcarriers or resource blocks (RBs) ) within a carrier, within a guard-band of a carrier, or outside of a carrier.
[0072] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0073] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being 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 the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0074] 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 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects 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 may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0075] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately 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 the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0076] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0077] A network entity 105 (e.g., a base station 140, an RU 170) or a 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) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0078] 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 the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0079] The wireless communications system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. An RLC layer may perform packet segmentation and reassembly to communicate via logical channels. A MAC layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer also may implement error detection techniques, error correction techniques, or both to support retransmissions to improve link efficiency. In the control plane, an RRC layer may provide establishment, configuration, and maintenance of an RRC connection between a UE 115 and a network entity 105 or a core network 130 supporting radio bearers for user plane data. A PHY layer may map transport channels to physical channels.
[0080] The UEs 115 and the network entities 105 may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., the communication link (s) 125, a D2D communication link 135) . HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC) ) , forward error correction (FEC) , and retransmission (e.g., automatic repeat request (ARQ) ) . HARQ may improve throughput at the MAC layer in relatively poor radio conditions (e.g., low signal-to-noise conditions) . In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval.
[0081] The wireless communications system 100 may support deployment of EH-capable devices such as AIoT devices or radio frequency identification (RFID) devices. For example, one or more UEs 115 may be EH-capable devices. EH-capable devices such as AIoT devices may be used for various applications. For example, two groupings of AIoT devices may be defined, where group A may be defined on the basis of employment environment (e.g., indoor, outdoor, or indoor / outdoor) and group B may be defined on the basis of functionality or application (e.g., inventory tracking, sensing, positioning, or command systems) . An EH-capable device may perform a backscatter based communication (e.g., transmit data) via backscattering an interrogating signal received from another wireless communications device (e.g., a reader device such as a UE 115 or a network entity 105) .
[0082] EH-capable devices may include multiple functions stored in memory. An interrogating device may issue a write command to modify a portion of memory or an erase command to erase a portion of memory of the EH-capable device. An interrogating device (e.g., a UE 115 or a network entity 105) may transmit a modify command to an EH-capable device that modifies two or more functions, where the functions are stored in discontinuous memory locations in the EH-capable device. In some examples, the modify command may indicate (e.g., via bits corresponding to the memory bank of the EH-capable device) which functions will be written / modified. In some examples, the initial request may indicate the functions or memory locations that will be written, which may reduce the size of the modify command. In some examples, the initial request may indicate the resources (e.g., time and / or frequency resources) for the EH-capable device to transmit the acknowledgment to the request. Indicating which functions may be written in the request (e.g., a DCI like control message) may reduce the size of the modify command and thereby reduce power consumption at the EH-capable device. Additionally, or alternatively, a new deactivate command may be introduced to deactivate an EH-capable device for an indicated or predetermined amount of time.
[0083] FIG. 2 shows an example of a wireless communications system 200 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The wireless communications system 200 may implement aspects of the wireless communications system 100.
[0084] The wireless communications system 200 may include a network device 205, which may be an example of a UE 115 or a network entity 105 as described herein. The network device 205 may also be referred to as a wireless communication device. The network device 205 may be an example of an energy transfer device or an RFID reader. The wireless communications system 200 may include an EH-capable device 210. The EH-capable device 210 may be a UE 115 as described herein. The EH-capable device 210 may be capable of performing backscattering based communication. In some examples, the EH-capable device 210 may be an example of an IoT device, an AIoT device, an RFID tag, or any combination thereof. EH-capable devices may harvest energy over the air (e.g., via reception of an interrogating signal 215) and power transmission / reception circuitry 225 via using the energy of the interrogating signal to transmit a responsive signal 220 to the interrogating signal. Responsive signals 220 transmitted by RFID devices may be backscatter modulated (e.g., referred to as backscatter responses) . In some examples, RFID devices may be semi-passive or active and may include an energy storage device (e.g., a battery) . In some examples, a wireless communications system may support a bistatic structure, where one network device (e.g., the network device 205) transmits an energy transfer signal (e.g., the interrogating signal 215) to the EH-capable device 210 and another network device may receive the responsive signal 220 (e.g., may communicate with the EH-capable device) .
[0085] EH-capable devices may be passive, semi-passive, or active. Table 1 below shows characteristics of passive, semi-passive, and active EH-capable devices. Example applications for passive EH-capable devices include access or proximity cards. Example applications for semi-passive EH-capable devices include electronic tolls or pallet tracking. Example applications for active EH-capable devices include large asset tracking or livestock tracking.
[0086] Table 1
[0087] Passive EH-capable devices may have short range capability (e.g., less than 10 meters) due to insufficient link budget issues and poor communication reliability. For example, the maximum transmit power by the network device 205 may be limited for the transmission band. For example, the effective isotropic radiated power (EIRP) for the network device may be 36 dBm. As another example, weak reflected backscatter signal by passive EH-capable devices may limit the range of the passive EH-capable devices. As passive EH-capable devices are power limited, the reflected signal power strength is approximately inversely proportional to the fourth power of the distance Another issue affecting the range of passive EH-capable devices may be interference from other reader devices, other tags, and / or other communications systems. Cyclic redundancy check (CRC) may be used for error detection for signals involving passive EH-capable devices.
[0088] As described herein, AIoT devices such as the EH-capable device 210 may be used for command systems in both indoor and outdoor environments. For example, Table 2 shows different example use cases for indoor AIoT devices and parameters associated with the use cases. Table 3 shows different example use cases for outdoor AIoT devices and parameters associated with the use cases.
[0089] Table 2
[0090] Table 3
[0091] In some examples, the network device 205 may transmit a write command to the EH-capable device 210. A write command may allow an interrogating device (e.g., the network device 205) to write a word in the reserved memory, the electronic product code (EPC) memory, the tag identifier (TID) memory, or the user memory of the EH-capable device 210. Prior to transmission of a write command, the network device 205 may transmit a random number request (also referred to as a Req_RN) to the EH-capable device. The EH-capable device 210 may generate a random number and may transmit an acknowledgment to the random number request that includes the random number. The write command may include the random number as a security check. In some examples, the EH-capable device 210 may transmit a response to a write command. Table 4 shows an example of information included in a write command, and Table 5 shows an example of information included in a response to a write command. As shown in Table 4, a write command may include a field indicating the command is a write command, an indication of the memory bank to modify, an address pointer within the memory bank, a data field to be written to the indicated address, the random number, and a CRC field. As shown in Table 5, the response from the EH-capable device 210 may include a header indicating the write command was successful, the random number as a security check, and a CRC field.
[0092] Table 4
[0093] Table 5
[0094] In some examples, the network device 205 may transmit a block write command to the EH-capable device 210. A block write command may allow an interrogating device (e.g., the network device 205) to write multiple words in the reserved, EPC, TID, or user memory of the EH-capable device 210 using a single command. A block write command may apply to a single memory bank. Prior to transmission of a block write command, the network device 205 may transmit a random number request to the EH-capable device 210 similarly to the process for transmission of a write command. Table 6 shows an example of information included in a block write command, and Table 7 shows an example of information included in a response to a block write command. As shown in Table 6, a block write command may include a field indicating the command is a block write command, an indication of the memory bank to modify, an address pointer within the memory bank indicating the starting address to begin the block write, an indicator of the number of words to be written, a data field to be written to the indicated addresses, the random number, and CRC field. As shown in Table 7, the response from the EH-capable device 210 may include a header indicating the block write command was successful, the random number as a security check, and a CRC field.
[0095] Table 6
[0096] Table 7
[0097] In some examples, the network device 205 may transmit a block erase command to the EH-capable device 210. A block erase command may allow an interrogating device (e.g., the network device 205) to erase multiple words in the reserved, EPC, TID, or user memory of the EH-capable device 210 using a single command. A block erase command may apply to a single memory bank. Prior to transmission of a block erase command, the network device 205 may transmit a random number request to the EH-capable device 210 similarly to the process for transmission of a write command. Table 8 shows an example of information included in a block erase command, and Table 9 shows an example of information included in a response to a block erase command. As shown in Table 8, a block erase command may include a field indicating the command is a block erase command, an indication of the memory bank to erase, an address pointer within the memory bank indicating the starting address to begin the block erase, an indicator of the number of words to be erased, the random number, and CRC field. As shown in Table 9, the response from the EH-capable device 210 may include a header indicating the block erase command was successful, the random number as a security check, and a CRC field.

[0100] In some examples, the network device 205 may transmit a kill command to the EH-capable device 210. The kill command may allow an interrogating device (e.g., the network device 205) to recommission a recomissionable tag (e.g., the EH-capable device) . To kill or recommission the EH-capable device 210, the network device 205 may follow a multi-step procedure. For example, the network device 205 may issue two kill commands, the first containing the 16 most significant bits (MSBs) of the kill password of the EH-capable device 210 with a 16 bit random number (indicated by the EH-capable device 210 in response to a request from the network device 205 similarly to a write command as described herein) and the second kill command including the 16 least significant bits (LSBs) of the kill password of the EH-capable device 210 with a different 16 bit random number indicated by the EH-capable device 210 in response to a request from the network device 205 similarly to a write command as described herein) . For example, the kill password may be predefined or known to the network device 205. For example, just prior to issuing each kill command, the network device 205 may issue a Req_RN to obtain a new 16 bit random number similarly to the process for a write command as described herein. The procedure for killing or recommissioning an EH-capable device 210 may be identical, except that the recommissioning bits in a second kill command may be set to zero when killing an EH-capable device 210 and the recommissioning bits in a second kill command may be set to non-zero when recommissioning an EH-capable device 210. Table 10 shows an example of information included in a first kill command, Table 11 shown an example of information included in a second kill command, Table 12 shows an example of a response to a first kill command, and Table 13 shows an example of a response to a successful second kill command.

[0103] Table 12
[0104] Table 13
[0105] For AIoT devices, the network may have a demand to modify information stored on the AIoT device similarly to a write command or a block write command or similarly to DCI format 1_X in NR. For AIoT devices, the network may demand to deactivate or activate the AIoT device. Permanent deactivation may be similar to a kill command, and temporary deactivation may be similar or discontinuous reception (DRX) in NR.
[0106] The write command, block write command, and erase command, as in RFID, may be used within the specified memory locations. For AIoT devices, however, in some examples, the network may demand to modify more than one function stored in discontinuous memory locations at the AIoT device.
[0107] In RFID, the kill command may be used to permanently kill or recommission an RFID device. However, for AIoT devices, the network may demand temporary deactivation (e.g., as in DRX for NR) . Monitoring physical downlink control channels (PDCCHs) for DCI indicating to modify multiple functions or to temporarily deactivate the AIoT device, however, may be computationally intensive and power consuming for an AIoT device.
[0108] Accordingly, as described herein, to avoid the latency associated with multiple write or erase commands, an interrogating device may transmit a modify command (e.g., a write command or an erase command) to an EH-capable device that modifies (e.g., writes or erases) two or more functions, where the functions are stored in discontinuous memory locations in the EH-capable device. Additionally, or alternatively, a new deactivate command may be introduced to deactivate an EH-capable device for an indicated or predetermined amount of time.
[0109] FIG. 3 shows an example of a wireless communications system 300 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The wireless communications system 300 may implement aspects of the wireless communications system 100 or the wireless communications system 200. For example, the wireless communications system 300 includes a network device 205-a, which may be an example of a network device 205 as described herein. As another example, the wireless communications system 300 includes an EH-capable device 210-a, which may be an example of an EH-capable device 210 as described herein.
[0110] The network device 205-a may transmit a modify command 320 to the EH-capable device 210-a that modifies two or more functions (e.g., a command that writes or erases two or more functions) . In some examples, the network device 205-a may transmit a control message 310 to the EH-capable device 210-a prior to transmission of the modify command 320, and the EH-capable device 210-a may transmit an acknowledgment 315 in response to the control message 310. The network device 205-a may transmit the modify command 320 based on the acknowledgment 315. For example, the control message 310 may include a random number request, the acknowledgment 315 may indicate a random number generated by the EH-capable device 210-a, and the modify command 320 may indicate the random number as a security check.
[0111] In some examples, the network device 205-a may reuse the write or block write command as described with reference to FIG. 2 and Tables 4–7 for the modify command 320-for example, if the EH-capable device 210-a supports only one function or if the network device 205-a demands to modify a single function or a set of functions located in continuous memory locations of the EH-capable device 210-a. As another example, if the EH-capable device 210-a supports more than one function, the network device 205-a may use the block write command as described with reference to FIG. 2 and Tables 6–7 as the modify command 320 to modify all of the functions of the EH-capable device 210-a in a same memory bank (e.g., setting the memory bank field as shown in Table 6 to “11” ) .
[0112] In some examples, the network device 205-a may modify two or more of the functions located in discontinuous memory locations of the EH-capable device 210-a of the EH-capable device 210-a in the modify command 320. In some such examples, the user memory of the EH-capable device 210-a may be divided based on the quantity of supported functions of the EH-capable device 210-a, and the quantity of bits in the modify command 320 used to indicate the functions to be modified may depend on the maximum quantity of functions the EH-capable device 210-a may support among all EH-capable devices of the same class. In some examples, the modify command 320 may be similar to a block write command as described with reference to Table 6, except the quantity of bits for the memory bank field may be increased to indicate the different functions or different combinations of functions of the EH-capable device 210-a to modify in the modify command 320. In some examples, the modify command 320 may be similar to a block write command as described with reference to Table 6, except a new bit field may be added (e.g., after the memory bank field) to indicate the different functions or different combinations of functions of the EH-capable device 210-a to modify in the modify command 320, for example, as shown in Table 14. In some examples, the modify command 320 may be similar to a block write command as described with reference to Table 6, except multiple bit fields may be used to indicate the location of each function, for example, as shown in Table 15. For example, for functions that the network device 205-a does not modify via the modify command 320, the Word Pointer and / or Word Count fields may be set to a default value (e.g., all “0” s) , and for functions that the network device 205-a modifies via the modify command 320, the Word Pointer and / or Word Count fields may be set to a different value.

[0114] Table 15
[0115] Table 15 Continued
[0116] In some examples, the resource for the EH-capable device 210-a to transmit a response to the modify command 320 may be similar to a response to an RFID read command. For example, the resource for the EH-capable device 210-a to transmit a response to the modify command 320 may be predefined or preconfigured with respect to the resource for the corresponding modify command 320 (e.g., a time gap between the modify command 320 and the starting position of the response 325 and the frequency shift with respect to the modify command may be predefined or preconfigured) . For example, if the EH-capable device 210-a successfully received the modify command 320, the EH-capable device 210-a may directly use a tag reply to transmit a response 325 indicating the EH-capable device 210-a successfully received the modify command 320. If the EH-capable device 210-a does not successfully receive the modify command 320, the EH-capable device 210-a may not transit a response 325, thereby indicating to the network device 205-a that the EH-capable device 210-a did not successfully receive the modify command.
[0117] In some examples, the control message 310 may indicate the which functions will be modified by the modify command 320. For example, the control message 310 may be a DCI like signal. The modify command 320 may be a separate data channel which indicates the modified data. The control message 310 may indicate which resource for the EH-capable device 210-a to monitor for the modify command 320 (e.g., the control message 310 may schedule the modify command 320) . The control message 310 may indicate the resource for the acknowledgment 315 and / or the response 325 (e.g., both the time and frequency resources or just the time in which case the frequency offset may be predefined or preconfigured) . In some examples, the starting point of the response 325 may be preconfigured with reference to the modify command 320 and / or the starting point of the acknowledgment 315 may be preconfigured with reference to the control message 310 (e.g., the duration between the response 325 and the modify command 320 or the acknowledgment 315 and the control message 310 may be based on a minimum time gap between the reception of the control / data signal and the corresponding response) . In some examples, the frequency shift between the response 325 and the modify command and / or between the acknowledgment 315 and the control message 310 may be preconfigured. In some examples, a mapping rule for the resource for a response (e.g., the acknowledgment 315 and / or the response 325) may be predefined with reference to the control / data message (e.g., the control message 310 and the modify command 320) .
[0118] In some examples, the control message 310 may include a bit that indicates whether the control message 310 is for a read command or a write command (e.g., a modify command 320) . For example, a value “0” may indicate a read command and a value “1” may indicate a write command. As another example, one scrambling sequence may be used to indicate a read command and another scrambling sequence may indicate a write command. As another example, different monitoring occasions may be configured for control messages for read commands and write commands.
[0119] In some examples, the EH-capable device 210-a may transmit the response 325 (e.g., an acknowledgment) if the EH-capable device 210-a successfully received the modify command 320 after receiving the control message 310 that indicated which functions will be modified. For example, the response 325 may be a sequence based acknowledgment or may be a one-bit acknowledgment. In some examples, the EH-capable device 210-a may not transmit the response 325 if the EH-capable device 210-a did not successfully receive the modify command 320 after receiving the control message 310 that indicated which functions will be modified.
[0120] In some examples, whether the control message 310 or the modify command 320 indicates which functions will be modified may be signaled or configured. For example, the modify command 320 indicating which functions will be modified may be referred to as “Type 1” and the control message 310 indicating which functions will be modified may be referred to as “Type 2. ” The network device 205-a and the EH-capable device 210-a may agree or communicate upon whether Type 1 or Type 2 will be used. For example, a switching signal 330 may be used to indicate a switch from Type 1 to Type 2 or vice versa. In some examples, the switching signal may be based on a switching request 335 from the EH-capable device 210-a.
[0121] As another example, within Type 2, whether the control message 310 indicates the time and / or frequency resource for the response 325 (e.g., referred to as “Type 2.1” ) or whether the resource for the response 325 is based on a predefined mapping rule (e.g., referred to as “Type 2.2” ) may be agreed upon or communicated between the network device 205-a and the EH-capable device 210-a.
[0122] For example, in some examples, the network device 205-a may start with Type 2.2 (e.g., Type 2.2 may be the default) and the network device 205-a may transmit a switching signal 330 to indicate switching to Type 2.1. For example, if the EH-capable device 210-a may decode the control message 310 successfully with a minimum required repetition, then the network device 205-a may transmit the switching signal 330 to indicate switching to Type 2.1. As another example, if the energy status of the EH-capable device 210-a is better than a threshold (e.g., the stored energy of the EH-capable device 210-a is higher than a threshold or the energy conversion efficiency is higher than a threshold) , the network device 205-a may switch from Type 2.2 to Type 2.1. In some examples, the EH-capable device 210-a may transmit a switching request 335, and the switch to Type 2.1 or the switching signal 330 indicating the switch to Type 2.1 may be responsive to the switching request 335. In some examples, the EH-capable device 210-a may transmit EH feedback to the network device 205-a, and the network device 205-a may determine whether to switch to Type 2.1 based on the EH feedback.
[0123] In some examples, the network device 205-a may start with Type 2.1 (e.g., Type 2.1 may be the default) and the network device 205-a may transmit a switching signal 330 to indicate switching to Type 2.2. For example, if the quantity of control signal transmissions that the EH-capable device 210-a does not respond to exceeds a threshold, the network device 205-a may trigger switching to Type 2.2. As another example, if the energy status of the EH-capable device 210-a is worse than a threshold (e.g., the stored energy of the EH-capable device 210-a is lower than a threshold or the energy conversion efficiency is lower than a threshold) , the network device 205-a may switch from Type 2.1 to Type 2.2. In some examples, the EH-capable device 210-a may transmit a switching request 335, and the switching signal 330 may confirm the switching.
[0124] In some examples, the network device 205-a may use a kill command as described with reference to FIG. 2 and Tables 10–13 to deactivate the EH-capable device 210-a. For example, the kill command may be used for the network device 205-a to permanently deactivate the EH-capable device 210-a. As another example, to deactivate the EH-capable device 210-a for a duration, the network device 205-a may issue a kill command first and may subsequently issue a recommission command. Kill commands followed by recommission commands may be used for infrequent deactivation and activation.
[0125] In some examples, the network device 205-a may transmit a new deactivation / activation command 340. The command code for the deactivation / activation command 340 may be different (e.g., the reserved code in RFID) to distinguish from the kill command. In some examples, if the EH-capable device 210-a has sufficient energy to maintain a clock at the EH-capable device 210-a, the deactivation / activation command 340 may indicate a duration (e.g., for how long) the EH-capable device 210-a should remain deactivated or activated. For example, Table 16 shows an example of information included in a deactivation / activation command 340 that includes a field that indicates a deactivation / activation duration.
[0126] Table 16
[0127] In some examples (e.g., if the EH-capable device 210-a does not have sufficient energy to maintain a clock at the EH-capable device 210-a) , the deactivation / activation command 340 may be split into a deactivate command (e.g., the deactivation / activation command 340) and an activate command (e.g., a second deactivation / activation command 345) . For example, the deactivation / activation command 340 may include an indication of the duration but the network device 205-a may also transmit a second deactivation / activation command 345 to activate the EH-capable device 210-a after deactivating the EH-capable device 210-a. As another example, the deactivation / activation command 340 may remove the bit field that indicates the duration (e.g., for how long) the EH-capable device 210-a should remain deactivated or activated and may also transmit a second deactivation / activation command 345 to activate the EH-capable device 210-a after deactivating the EH-capable device 210-a. For example, Table 17 shows an example of information included in a deactivation / activation command 340 that removes a field that indicates a deactivation / activation duration.
[0128] Table 17
[0129] In some examples, the network device 205-a may use a device or group specified sequence for deactivating and activating the EH-capable device, similarly to wake-up signals (WUS) and go to sleep signals. For example, the deactivation / activation command 340 may indicate for the EH-capable device to enter a sleep mode during which the EH-capable device may monitor for the second deactivation / activation command 345 which may act as a WUS.
[0130] In some examples, the network device 205-a may configure or pre-configure an activation and / or deactivation duration for the EH-capable device, for example, via the deactivation / activation command 340 (e.g., similar to DRX in NR) . For example, if the EH-capable device 210-a has sufficient energy to maintain a clock at the EH-capable device 210-a, the EH-capable device may activate and deactivate in accordance with the indicated pattern or duration in a deactivation / activation command 340. For example, if the clock variation of the EH-capable device 210-a is N slots between each synchronization duration, then the EH-capable device 210-a may be configured to enter the activate status with N slots earlier and enter the deactivates status with N slots later.
[0131] FIG. 4 shows an example of a signaling timing diagram 400 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The signaling timing diagram 400 may implement aspects of the wireless communications system 100, the wireless communications system 200, or the wireless communications system 300.
[0132] As described herein, in some examples, as shown in the example signaling timing diagram 405, the network device 205 may start with Type 2.2 (e.g., Type 2.2 may be the default) and the network device 205 may transmit a switching signal 330 to indicate switching to Type 2.1. For example, the network device 205 may transmit a control message 410 of Type 2.2 (e.g., a control message 310 as described with reference to FIG. 3) and the EH-capable device 210 may transmit a response 415 indicating the control message 410 was correctly received. The network device 205 may subsequently transmit a control message 420 of Type 2.2 (e.g., a control message 310 as described with reference to FIG. 3) and the EH-capable device 210 may transmit a response 425 indicating the control message 420 was correctly received. At time T1, after transmission of the response 425, the EH-capable device 210 may determine that the energy status of the EH-capable device 210 is better than a threshold. Accordingly, the EH-capable device 210 may transmit a switching request 430 (e.g., a switching request 335 as described with reference to FIG. 3) and in response the network device 205 may transmit a switching indication 435 (e.g., a switching signal 330 as described with reference to FIG. 3) . The EH-capable device 210 may transmit an acknowledgment 440 to the switching indication 435. The network device 205 may subsequently transmit a control message 445 of Type 2.1 (e.g., a control message 310 as described with reference to FIG. 3) .
[0133] As described herein, in some examples, as shown in the example signaling timing diagram 450, the network device 205 may start with Type 2.1 (e.g., Type 2.1 may be the default) and the network device 205 may transmit a switching signal 330 to indicate switching to Type 2.2. For example, the network device 205 may transmit a control message 455 of Type 2.1 (e.g., a control message 310 as described with reference to FIG. 3) and the EH-capable device 210 may transmit a response 460 indicating the control message 455 was correctly received. The network device 205 may subsequently transmit a control message 465 of Type 2.1 (e.g., a control message 310 as described with reference to FIG. 3) and the EH-capable device 210 may transmit a response 470 indicating the control message 465 was correctly received. At time T1, after transmission of the response 425, the EH-capable device 210 may determine that the energy status of the EH-capable device 210 is worse than a threshold. Accordingly, the EH-capable device 210 may transmit a switching request 475 (e.g., a switching request 335 as described with reference to FIG. 3) and in response the network device 205 may transmit a switching indication 480 (e.g., a switching signal 330 as described with reference to FIG. 3) . The EH-capable device 210 may transmit an acknowledgment 485 to the switching indication 480. The network device 205 may subsequently transmit a control message 490 of Type 2.2 (e.g., a control message 310 as described with reference to FIG. 3) .
[0134] FIG. 5 shows an example of a timing diagram 500 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The timing diagram 500 may implement aspects of the wireless communications system 100, the wireless communications system 200, or the wireless communications system 300.
[0135] In some examples, as shown in the timing diagram 505, a first deactivation / activation command 510 may deactivate an EH-capable device 210 and a second deactivation / activation command 515 may activate the EH-capable device 210. Thus, the EH-capable device 210 may be inactive for a duration 520. For example, subsequent deactivation / activation commands may be used if the EH-capable device 210 does not have sufficient energy to maintain a clock.
[0136] In some examples, as shown in the timing diagram 525, if the EH-capable device 210 has sufficient energy to maintain a clock, a deactivation / activation command 530 may indicate a deactivation duration 540. After the deactivation duration 540, the EH-capable device 210 may reenter the active state.
[0137] In some examples, as shown in the timing diagram 550, a network device may configure a periodic activation and deactivation pattern. For example, the EH-capable device 210 may be active during the durations 560 and the EH-capable device 210 may be deactivated during the duration 565. Guard durations 555 may separate the durations 560 in which the EH-capable device 210 is active from the duration 565 during which the EH-capable device 210 is deactivated to account for potential clock variation between the EH-capable device 210 and the network device 205.
[0138] FIG. 6 shows an example of a process flow 600 that supports scheduling and resource allocation for EH-capable devices in accordance with one or more aspects of the present disclosure. The process flow 600 may include a network device 205-b, which may be an example of a network device 205 as described herein. The process flow 600 may include an EH-capable device 210-b, which may be an example of an EH-capable device 210 as described herein. In the following description of the process flow 600, the operations between the network device 205-b and the EH-capable device 210-b may be transmitted in a different order than the example order shown, or the operations performed by the network device 205-b and the EH-capable device 210-b may be performed in different orders or at different times. Some operations may also be omitted from the process flow 600, and other operations may be added to the process flow 600.
[0139] At 605, the EH-capable device 210-b may receive, from the network device 205-b, a control message that indicates a request to transmit a modify command to the EH-capable device 210-b. The modify command may be associated with modifying two or more functions stored in discontinuous memory locations of the EH-capable device 210-b.
[0140] At 610, the EH-capable device 210-b may transmit, to the network device 205-b, an acknowledgment in response to the control message, the acknowledgment indicating that transmission of the modify command is permitted for modifying the two or more functions.
[0141] At 615, the EH-capable device 210-b may receive, from the network device 205-b and based on the acknowledgment, the modify command for the two or more functions of the EH-capable device 210-b stored in the discontinuous memory locations of the EH-capable device 210-b.
[0142] In some examples, the control message at 605 may include an indication of the two or more functions to be modified.
[0143] In some examples, the EH-capable device 210-b may receive, from the network device 205-b, a switching signal that indicates to switch from a first mode of operation to a second mode of operation, where the first mode of operation is associated with a control message-based indication of functions to modify and the second mode of operation is associated with a modify command-based indication of the functions to modify, or where the first mode of operation is associated with the modify command-based indication of the functions to modify and the second mode of operation is associated with the control message-based indication of the functions to modify.
[0144] In some examples, the control message at 605 may include an indication of a communication resource for transmission of the acknowledgment, where the acknowledgment is transmitted via the communication resource.
[0145] In some examples, the control message at 605 may include an indication of a communication resource for transmission of a response to the modify command, and the EH-capable device 210-b may transmit a response indicating successful reception of the modify command via the communication resource.
[0146] In some examples, the modify command at 615 may indicate the two or more functions to be modified.
[0147] In some examples, the control message at 605 may include a random number request, the acknowledgment at 610 may include an indication of a random number based on the random number request, and the modify command at 615 may include the random number.
[0148] In some examples, the EH-capable device 210-b may receive, from the network device 205-b, a deactivation command, where the deactivation command includes an indication of a deactivation duration. The EH-capable device 210-b may enter a deactivated state for the deactivation duration based on the deactivation command.
[0149] In some examples, the EH-capable device 210-b may receive, from the network device 205-b, a deactivation command and an indication of one or more WUS monitoring occasions. The EH-capable device 210-b may monitor for a WUS in the one or more WUS monitoring occasions, and the network device 205-b may transmit a WUS in one of the one or more WUS monitoring occasions to activate the EH-capable device 210-b (e.g., trigger the EH-capable device to enter an active state from a deactivated state) .
[0150] In some examples, the EH-capable device 210-b may receive, from the network device 205-b, a second control message configuring a pattern for deactivation and activation of the EH-capable device 210-b, where the pattern includes an activated mode and a deactivated mode for the EH-capable device 210-b, the pattern cycling between the activated mode and the deactivated mode. The EH-capable device 210-b may cycle between the activated mode and the deactivated mode in accordance with the pattern for deactivation and activation of the EH-capable device 210-b.
[0151] FIG. 7 shows a block diagram 700 of a device 705 that supports scheduling and resource allocation for energy-harvesting capable devices in accordance with one or more aspects of the present disclosure. The device 705 may be an example of aspects of a UE 115 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communications manager 720. The device 705, or one or more components of the device 705 (e.g., the receiver 710, the transmitter 715, the communications manager 720) , may include at least one processor, which may be coupled with at least one memory, to, individually or collectively, support or enable the described techniques. The device 705 may also include one or more processors, memory coupled with the one or more processors, and instructions stored in the memory that are executable by the one or more processors to enable the one or more processors to perform the scheduling and resource allocation for energy-harvesting capable devices features discussed herein. Each of these components may be in communication with one another (e.g., via one or more buses) .
[0152] The receiver 710 may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to scheduling and resource allocation for energy-harvesting capable devices) .

For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0256] The various illustrative blocks and components described in connection with the disclosure herein may be implemented or performed using a general-purpose processor, a DSP, an ASIC, a CPU, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general-purpose processor may be a microprocessor but, in the alternative, the processor may be any processor, controller, microcontroller, or state machine. A 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) . Any functions or operations described herein as being capable of being performed by a processor may be performed by multiple processors that, individually or collectively, are capable of performing the described functions or operations.
[0257] The functions described herein may be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions may be stored as or transmitted using one or more instructions or code of a computer-readable medium. Other examples and implementations are within the scope of the disclosure and appended claims. For example, due to the nature of software, functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or combinations of any of these. Features implementing functions may also be physically located at various positions, including being distributed such that portions of functions are implemented at different physical locations.
[0258] Computer-readable media includes both non-transitory computer storage media and communication media 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 may be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM) , flash memory, compact disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that may be used to carry or store desired program code means in the form of instructions or data structures and that may 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 the software is transmitted from a website, server, or other remote source using a 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. Disk and disc, as used herein, include CD, laser disc, optical disc, digital versatile disc (DVD) , floppy disk, and Blu-ray disc. Disks may reproduce data magnetically, and discs may reproduce data optically using lasers. Combinations of the above are also included within the scope of computer-readable media. Any functions or operations described herein as being capable of being performed by a memory may be performed by multiple memories that, individually or collectively, are capable of performing the described functions or operations.
[0259] As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” ) indicates an inclusive list such that, for example, a list 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) . Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on. ”
[0260] As used herein, including in the claims, the article “a” before a noun is open-ended and understood to refer to “at least one” of those nouns or “one or more” of those nouns. Thus, the terms “a, ” “at least one, ” “one or more, ” and “at least one of one or more” may be interchangeable. For example, if a claim recites “a component” that performs one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “a component” having characteristics or performing functions may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent reference to a component introduced with the article “a” using the terms “the” or “said” may refer to any or all of the one or more components. For example, a component introduced with the article “a” may be understood to mean “one or more components, ” and referring to “the component” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ” Similarly, subsequent reference to a component introduced as “one or more components” using the terms “the” or “said” may refer to any or all of the one or more components. For example, referring to “the one or more components” subsequently in the claims may be understood to be equivalent to referring to “at least one of the one or more components. ”
[0261] The term “determine” or “determining” encompasses a variety of actions and, therefore, “determining” can include calculating, computing, processing, deriving, investigating, looking up (such as via looking up in a table, a database, or another data structure) , ascertaining, and the like. Also, “determining” can include receiving (e.g., receiving information) , accessing (e.g., accessing data stored in memory) , and the like. Also, “determining” can include resolving, obtaining, selecting, choosing, establishing, and other such similar actions.
[0262] In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If just the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label or other subsequent reference label.
[0263] The description set forth herein, in connection with the appended drawings, describes example configurations and does not represent all the examples that may be implemented or that are within the scope of the claims. The term “example” 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 the purpose of providing an understanding of the described techniques. These techniques, however, may be practiced without these specific details. In some figures, known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
[0264] The description herein is provided to enable a person having ordinary skill in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to a person having ordinary skill in the art, and the generic principles defined herein may be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described herein but is to be accorded the broadest scope consistent with the principles and novel features disclosed herein.
