[0002] This patent application claims the benefit of Greek Provisional Patent Application No. 20210100347 entitled “WAKING-UP AWIRELESSLY-POWERED DEVICE” filed by ELSHAFIE et al. on May 26, 2021, which has been assigned to the assignee of this application. Technical Field
[0003] The following pertains to wireless communication, including waking up wirelessly powered devices. Background Technology
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems such as Long Term Evolution (LTE), LTE-A Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems can 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 Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as User Equipment (UE).
[0005] The UE can communicate with another UE or a base station. In some examples, the UE can perform discontinuous reception (DRX), which may include an ON duration during which the UE can monitor the control channel for signals. Effective use of the ON duration can present challenges. Summary of the Invention
[0006] The described technology relates to improved methods, systems, devices, and apparatuses for supporting the wake-up of wirelessly powered devices. Typically, the described technology provides a first user equipment (UE) that determines whether to harvest energy from a signal, decode data from a signal, or both. For example, a wireless device (e.g., a base station, a second UE) may send a wake-up message including an indicator of whether the on-time duration of a discontinuous reception period is associated with harvesting energy from a signal transmitted during the on-time duration. The wireless device may transmit a signal during the on-time duration based on the wake-up message. In some examples, the first UE can determine, based on the indicator, whether to harvest energy, decode data, or both during the on-time duration. If both energy is harvested and data is decoded, the UE can concurrently harvest energy and decode data during at least a portion of the on-time duration. Additionally or alternatively, the UE can harvest energy during a first portion of the on-time duration and decode data during a second portion of the on-time duration.
[0007] A method for wireless communication at a user equipment (UE) is described. The method may include receiving a wake-up message including an indicator of whether an on-duration of a discontinuous reception period is associated with energy harvesting from a signal transmitted during the on-duration, and receiving the signal during the on-duration based on the wake-up message.
[0008] An apparatus for wireless communication at a UE is described. The apparatus may include one or more processors, a memory coupled to the one or more processors, and instructions stored in the memory.

[0055] A user equipment (UE) can communicate with a wireless device, such as a base station or another UE. In some examples, the UE can continuously monitor a channel (e.g., a control channel). However, continuous channel monitoring can be associated with higher energy consumption for the UE than suppressing channel monitoring. To enable the UE to use less energy while monitoring a channel, the UE can perform discontinuous reception (DRX), which can include switching between an active state during an on duration (e.g., the UE monitoring the state of one or more channels for communication with a wireless device) and an inactive state during an off duration (e.g., the UE suppressing the state of monitoring one or more channels). Thus, the UE can receive signals from the wireless device on the monitored channel during the on duration and can not receive signals on the monitored channel during the off duration.
[0056] In some examples, an on duration and a consecutive off duration can form a DRX cycle. In some examples, the on duration can be the period during which the UE is active and able to monitor the channel, while the off duration can be the period during which the UE is inactive and unable to monitor the channel. In some examples, the UE can determine whether to switch to an active state during the on duration based on whether the UE receives a wake-up signal (WUS) before the on duration. For example, if the UE receives a WUS before the on duration, the UE can switch to an active state during the next on duration. However, if the UE does not receive a WUS before the on duration, the UE can remain inactive.
[0057] In some examples, the UE is able to harvest energy from the signal, decode data from the signal, or both. The methods disclosed herein describe how the UE can determine whether to harvest energy, decode data, or both from a signal received during the on-duration of DRX operation. For example, a WUS received by the UE can instruct the UE to harvest energy, decode data, or both during the on-duration. In some examples, the WUS can instruct the UE to concurrently harvest energy and decode data during the on-duration. In some examples, the WUS can instruct the UE to harvest energy during a first portion of the on-duration and to decode data during a second portion of the on-duration. Additionally or alternatively, if the UE fails to receive a WUS, the UE can determine, based on a set of parameters (e.g., one or more predetermined rules or parameter sets corresponding to probability values), whether to remain inactive, harvest energy, decode data, or harvest energy and decode data during the on-duration.

[0060] Figure 1 An example of a wireless communication system 100 supporting wake-up wirelessly powered devices according to various aspects of this disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-APro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof.
[0061] Base stations 105 can be distributed across a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, on which UE 115 and base station 105 can establish one or more communication links 125. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal communication according to one or more radio access technologies.
[0062] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 The diagram illustrates some example UE 115. For example... Figure 1 As shown, the UE 115 described herein can communicate with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices).
[0063] Base station 105 may communicate with core network 130, or with each other, or with both. For example, base station 105 may be connected to core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 may communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) via backhaul links 120 (e.g., via X2, Xn, or other interfaces), or both. In some examples, backhaul link 120 may be or include one or more radio links.
[0064] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as: base transceiver station, radio base station, access point, radio transceiver, node B, e-node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home e-node B or other suitable terms.
[0065] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein, among other examples, "device" may also be referred to as a cell, station, terminal, or client. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or 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 can be implemented in various objects, such as appliances or vehicles, meters, etc.
[0066] The UE 115 described in this document can communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base station 105 and network devices (including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations), and other examples, such as Figure 1 As shown.
[0067] UE 115 and base station 105 can wirelessly communicate with each other on one or more carriers via one or more communication links 125. The term "carrier" can refer to a set of radio spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion (e.g., a bandwidth portion (BWP)) of a radio 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 coordinating carrier operation, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0068] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located based on a channel grating used for discovery by UE 115. A carrier may operate in an independent mode, where UE 115 may perform initial acquisition and connection via a carrier, or the carrier may operate in a non-independent mode, where the connection is anchored using different carriers (e.g., the same or different radio access technologies).
[0069] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. A carrier may carry either downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).
[0070] A carrier can be associated with a specific bandwidth of the radio spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of defined bandwidths of a carrier used for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.
[0071] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements the UE 115 receives and the higher the order of the modulation scheme, the higher the data rate the UE 115 can potentially achieve. Wireless communication resources can refer to a combination of radio spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and using multiple spatial layers can further increase the data rate or data integrity of communication with the UE 115.
[0072] One or more parameter sets for a carrier can be supported, where the parameter sets may include subcarrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, the UE115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and the UE115's communication can be restricted to one or more active BWPs.
[0073] The time interval of base station 105 or UE 115 can be expressed as a multiple of a basic time unit, which can be, for example, T. s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N fThis can represent the maximum supported Discrete Fourier Transform (DFT) size. Communication resources can be organized into time intervals based on radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0074] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame (e.g., in the time domain) may be divided into subframes, and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots comprising one or more symbols. In addition to the cyclic prefix, each symbol period may include one or more (e.g., N) f Sampling period. The duration of the symbol period may depend on the subcarrier spacing or the operating frequency band.
[0075] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).
[0076] Physical channels can be multiplexed on a carrier using various techniques. Physical control channels and physical data channels can be multiplexed on a downlink carrier, for example, using one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques. The control region (e.g., a control resource set (CORESET)) of a physical control channel can be defined by multiple symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more UEs 115 can monitor or search for control regions based on 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 control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information in a control information format with a given payload size. The search space set can include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.
[0077] Each base station 105 may provide communication coverage through one or more cells, such as macro cells, small cells, hotspots, or other types of cells, or any combination thereof. The term "cell" may refer to a logical communication entity used to communicate with base station 105 (e.g., via a carrier) and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or others). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. The range of such cells can vary from small areas (e.g., structures, subsets of structures) to large areas, depending on various factors such as the capabilities of base station 105. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, among other examples.
[0078] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access for UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with a small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a home or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.
[0079] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).
[0080] In some examples, base station 105 may be mobile, and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.
[0081] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 can be time-disaligned. The techniques described herein can be used for both synchronous and asynchronous operation.
[0082] Some UE 115 devices (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 base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents it to people interacting with the application. Some UE 115 devices can 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 billing.
[0083] Some UE 115s can be configured to operate in reduced-power modes, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception, but not simultaneous transmission and reception). In some examples, half-duplex communication can be performed at a reduced peak rate. Other power-saving techniques for UE 115s include entering a power-saving deep sleep mode when not engaged in active communication, operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using narrowband protocol types associated with defined portions or ranges (e.g., subcarriers or resource blocks (RBs)) within a carrier, within a carrier's guard band, or outside the carrier.
[0084] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private or group communication and may be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.
[0085] In some examples, UE 115 may also be able to communicate directly with other UE 115 via device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more of the UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115 in the group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some examples, the group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates resource scheduling for D2D communication. In other cases, D2D communication between UEs 115 is performed without the involvement of base station 105.
[0086] In some systems, the D2D communication link 135 may be an example of a communication channel between vehicles (e.g., UE 115), such as a sidelink communication channel. In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these communications. Vehicles may signal information related to traffic conditions, signal control, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via vehicle-to-network (V2N) communication through one or more network nodes (e.g., base station 105), or communicate with both.
[0087] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) routing or interconnecting packets to external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by base station 105 associated with core network 130. User IP packets can be delivered through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0088] Some network devices (such as base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, smart radio head, or transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or combined into a single network device (e.g., base station 105).
[0089] Wireless communication system 100 can operate using one or more frequency bands, including those ranging from 300 MHz to 300 GHz. Typically, the region from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) region or decimeter band because wavelength distances range from approximately 1 decimeter to 1 meter. Building and environmental features may block or redirect UHF waves, but the waves can sufficiently penetrate the structure of a macrocell to provide service to the UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).
[0090] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band), or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the individual devices can be even smaller and more closely spaced than UHF antennas. In some examples, this can facilitate the use of antenna arrays within the devices. However, compared to SHF or UHF transmissions, EHF transmissions may experience even greater atmospheric attenuation and shorter range. The techniques disclosed herein can be employed between transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory body.
[0091] Wireless communication system 100 can utilize both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), unlicensed LTE (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in unlicensed radio spectrum bands, devices such as base station 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed bands can be configured based on carrier aggregation along with component carriers operating in licensed bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, etc.
[0092] Base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be located together at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.
[0093] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. This technique can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO technologies include single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.
[0094] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals communicating via antenna elements in an antenna array such that signals propagating in a specific azimuth relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicating via antenna elements can include applying offset, phase offset, or both to the signal carried by the transmitting or receiving device via the antenna element associated with that device. The adjustments associated with each antenna element can be defined by a beamforming weight set associated with a specific azimuth (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other direction).
[0095] Base station 105 or UE 115 may use beam scanning technology as part of beamforming operations. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) for beamforming operations for directional communication with UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by base station 105 in different directions, which may include transmitting signals according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by base station 105 or a receiving device such as UE 115) to identify the beam direction of subsequent transmissions or receptions by base station 105.
[0096] Some signals (such as data signals associated with a specific receiving device) may be transmitted by base station 105 in a single beam direction (e.g., the direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on the signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signals received by UE 115 with the highest signal quality or other acceptable signal quality.
[0097] In some examples, transmissions by a device (e.g., base station 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and this feedback may correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)). UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam direction for subsequent transmission or reception by UE 115), or to transmit signals in a single direction (e.g., to transmit data to a receiving device).
[0098] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by: receiving via different antenna subarrays; processing the received signals according to different antenna subarrays; receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets); or processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array. Any of these methods can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned based on a beam direction determined by listening in different receiver configuration directions (e.g., a beam direction determined by listening in multiple beam directions to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality).
[0099] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication over logical channels. The Media Access Control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between the UE 115 and the base station 105 or core network 130 that supports radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.
[0100] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correctly receiving data over communication link 125. HARQ can include a combination of error detection (e.g., using Periodic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under adverse radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support HARQ feedback within the same time slot, where the device can provide HARQ feedback in a specific time slot for data received in a previous symbol within that time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.
[0101] UE 115 can communicate with a wireless device, such as base station 105 or another UE. In some examples, UE 115 can continuously monitor a channel (e.g., a control channel). However, continuous channel monitoring can be associated with higher energy usage for UE 115 than suppressing channel monitoring. To enable UE 115 to use less energy while monitoring a channel, UE 115 can perform DRX, which may include switching between an active state during an on duration (e.g., UE 115 monitoring one or more channels to seek communication with a wireless device) and an inactive state during a off duration (e.g., UE 115 suppressing monitoring of one or more channels). Therefore, UE 115 can receive signals from a wireless device on the monitored channel during the on duration and can not receive signals on the monitored channel during the off duration.
[0102] In some examples, an on duration and a consecutive off duration can form a DRX cycle. In some examples, the on duration can be the period during which UE 115 can be active and able to monitor the channel, while the off duration can be the period during which UE 115 is inactive and unable to monitor the channel. In some examples, UE 115 can determine whether to switch to an active state during the on duration based on whether UE 115 receives a WUS before the on duration. For example, if UE 115 receives a WUS before the on duration, UE 115 can switch to an active state during the next on duration. However, if UE 115 does not receive a WUS before the on duration, UE 115 can remain inactive.
[0103] In some examples, UE 115 is capable of harvesting energy from a signal, decoding data from a signal, or both. The methods disclosed herein describe how UE 115 can determine from a signal received during the on-duration of DRX operation whether to harvest energy, decode data, or both. For example, a WUS received by UE 115 can instruct UE 115 whether to harvest energy, decode data, or both during the on-duration. In some examples, the WUS can instruct UE 115 to concurrently harvest energy and decode data during the on-duration. In some examples, the WUS can instruct UE 115 to harvest energy during a first portion of the on-duration and to decode data during a second portion of the on-duration. Additionally or alternatively, if UE 115 fails to receive a WUS, UE 115 can determine, based on a set of parameters (e.g., one or more predetermined rules or parameter sets corresponding to probability values), whether to remain inactive, harvest energy, decode data, or harvest energy and decode data during the on-duration.
[0104] Figure 2 An example of a wireless communication system 200 supporting wake-up of wirelessly powered devices according to various aspects of this disclosure is illustrated. In some examples, the wireless communication system 200 may implement one or more aspects of the wireless communication system 100. For example, the wireless device 202-a may be as described in the reference... Figure 1 The example described is UE 115 or base station 105, and UE 115-a can be as referenced. Figure 1 An example of UE 115 as described.
[0105] Wireless device 202-a can communicate with UE 115-a according to the DRX cycle. For example, UE 115-a can be configured with an on duration 225 (e.g., on duration 225-a, 225-b) and a off duration 220 (e.g., off duration 220-a, 220-b). During the on duration 225, UE 115-a can communicate with wireless device 202-a, and during the off duration 220, UE 115-a can suppress the execution of at least some types of communication with wireless device 202-a. In some examples, UE 115-a can determine whether to communicate with wireless device 202-a during the on duration 225 based on whether UE 115-a receives WUS 205 during the corresponding off duration 220. For example, if UE115-a receives WUS 205-a during the off duration 220-a, UE115-a can switch to the active state during the on duration 225-a, and if UE115-a receives WUS 205-b during the off duration 220-b, UE115-a can switch to the active state during the on duration 225-b. During the on duration 225, UE115-a can receive signals from radio device 202-a. For example, if UE115-a is active during the on duration 225-a, UE115-a can receive a first signal 210 from radio device 202-a. Additionally, if UE115-a is active during the on duration 225-b, UE115-a can receive a second signal 215 from radio device 202-a. In some examples, the DRX cycle can be an example of the connection mode DRX (CDRX). In some examples, the configuration of WUS205 can be configured via RRC signaling (e.g., from wireless device 202-a or from another device).
[0106] In some examples, UE 115-a may be able to harvest energy, decode data, or both from the first signal 210 or the second signal 215. In some examples, UE 115-a may harvest energy to assist in data decoding, data reception, data encoding, data transmission, or any combination thereof. In some examples, energy harvesting may extend the battery life of UE 115-a. Additionally, wirelessly powering UE 115-a allows multiple UE 115s to collaborate and relay signals from other UE 115s. Based on WUS205 (e.g., after receiving WUS205), UE 115-a may prepare its data link, its energy harvester circuitry, or both.
[0107] This disclosure can describe methods that enable UE 115-a to determine whether to collect energy, decode data, or both from the first signal 210 or the second signal 215. For example, each WUS 205 can indicate whether UE 115-a should use a corresponding on-duration 225 to collect energy, decode data, or both. In some examples, each WUS 205 can indicate collecting energy or decoding data (e.g., not both). For example, WUS 205-a can indicate collecting energy from the first signal 210, and WUS 205-b can indicate decoding data from the second signal 215. This document may refer to, for example, […]. Figure 4A Additional details are described below. Alternatively, each WUS205 may indicate energy harvesting, data decoding, or both. For example, WUS205-a may indicate energy harvesting from a first signal 210, and WUS205-b may indicate energy harvesting from a second signal 215 and data decoding.
[0108] In some examples where WUS205 instructs the acquisition of energy and decoding data, WUS205 may instruct the concurrent acquisition of energy and decoding data for at least a portion of the on-duration 225 (e.g., the entire on-duration). In some such examples, WUS205 may instruct a parameter ρ representing the proportion of energy of the received signal that UE 115-a intends to acquire or that UE 115-a intends to use for decoding. In some examples, concurrent acquisition of energy and decoding may be associated with, for example, referenced herein. Figure 3B The power splitting architecture described herein is associated with this. This document may refer to, for example, [reference needed]. Figure 4B Describe additional details.
[0109] In other examples where WUS205 instructs energy acquisition and data decoding, WUS205 may instruct energy acquisition during a first portion of the on-time duration 225 and data decoding during a second portion of the on-time duration 225 (e.g., where the first portion may follow the second portion, or the second portion may follow the first portion). In some such examples, WUS205 may include a parameter α indicating the length of the first portion for energy acquisition, the length of the second portion for data decoding, or both. In some examples, acquiring energy in the first portion and decoding data in the second portion before or after the first portion may be consistent with, for example, referenced herein. Figure 3A The time-switching architecture described is associated with this.
[0110] In other examples where WUS205 instructs the acquisition of energy and decoding data, WUS205 may instruct the acquisition of energy or decoding data during a portion of the on-duration 225 (e.g., not both), and during another portion of the on-duration 225 (e.g., concurrently for at least a portion of the other portion). In some such examples, WUS205 may instruct a first parameter ρ to indicate the length of the first portion, the second portion, or both, and may instruct a second parameter α to represent the proportion of energy that UE 115-a will acquire or that UE 115-a will use for decoding in the second portion. In some examples, using the first portion to acquire energy or decoding data and using the second portion to acquire both energy and decoding data may be consistent with, for example, referenced herein. Figure 3C The described individual panel architectures are related. This article may refer to, for example, the following: Figure 4C Describe additional details.
[0111] In some examples, UE 115-a may not be able to decode WUS205. In some such examples, UE 115-a can use configuration from radio device 202-a to wake up (e.g., become active) or sleep (e.g., remain inactive) during the on-duration. If awake, radio device 202-a can determine the corresponding on-duration 225 for decoding data, harvesting energy, or both. In some examples, the operation can be configurable. For example, whether UE 115-a should decode data, harvest energy, or both can be configured at UE 115-a by radio device 202-a or another device. Additionally or alternatively, UE 115-a can be configured by a random decision indication using a set of parameters associated with a corresponding probability set. For example, the first parameter p1 may indicate the probability that UE 115-a remains inactive, the second parameter p2 may indicate the probability that UE 115-a decodes data and does not collect energy, the third parameter p3 may indicate the probability that UE 115-a collects energy and does not decode data, and p4 may indicate the probability that UE 115-a collects energy and decodes data. In some examples, p4 may be associated with predefined ρ and α (e.g., defined via prior configuration signaling). In some examples, each of p1, p2, p3, and p4 may be configured by radio device 202-a. Additionally or alternatively, UE 115-a may use a deterministic probability model to determine whether to decode data, collect energy, or both. For example, UE 115-a may use a pseudo-random generator with a seed identified by UE 115-a and radio device 202-a. Therefore, both wireless device 202-a and UE 115-a can identify whether UE 115-a needs to be activated and whether UE 115-a needs to decode data, collect energy, or both.
[0112] In some examples, the WUS may be included in the Group Common Downlink Control Information (DCI) (e.g., DCI Format 2-6), or the Group Common DCI may be the WUS. In such examples, additional information may be provided to the UE (e.g., configured for DRX mode operation) for detecting the Group Common DCI in PDCCH reception on the primary cell (PCell) or secondary group primary cell (SPCell). For example, a network entity may send the additional information to the UE. In some cases, the additional information may include a Power Saving Radio Network Temporary Identifier (PS-RNTI) for the Group Common DCI. In some cases, the additional information may include multiple search space sets (e.g., configured by dci-Format 2-6) for the UE to monitor the PDCCH according to the common search space to detect the Group Common DCI on the active downlink BWP of the PCell or SPCell. In some cases, the additional information may include the payload size of the Group Common DCI (e.g., configured by sizeDCI_2-6). In some cases, the additional information may include (e.g., configured by psPositionDCI_2-6) the position of the wake-up indication bit in the Group Common DCI. A zero value for the wake-up indicator bit, when reported to a higher layer, can instruct the UE not to start a DRX timer (e.g., drxonDurationTimer) for the next long DRX cycle, while a one value for the wake-up indicator bit, when reported to a higher layer, can instruct the UE to start a DRX timer for the next long DRX cycle.
[0113] According to the techniques described herein, a group common DCI can be configured with one or more first additional fields for configuring UE 115-a to wake up during an active duration, and one or more second additional fields for configuring UE 115-a to decode data, collect energy, or decode data and collect energy, or both, during the active duration. One or more first additional fields can be used to configure active operation, and one or more second additional fields can be used to configure energy collection operation. Active operation can refer to switching to an active state or remaining in an inactive state during the active duration, and energy collection operation can refer to decoding data, collecting energy, or decoding data and collecting energy during the active duration. The group common DCI can be used for a group of UEs, and the additional fields in the group common DCI can be used for a single UE or the group of UEs. In some cases, UE 115-a can be guided or configured to read some fields in the group common DCI (e.g., including a one-bit field for active operation or energy collection operation), and UE 115-a can be guided or configured to read other configurations specific to UE 115-a (e.g., related to energy collection). In such a case, UE 115-a can use fields and other configurations in the group common DCI to determine the energy harvesting operation to be performed during the on-duration period (e.g., decoding data, harvesting energy, or both).
[0114] In some respects, the DCI used for configuring WUS for energy harvesting operations can be based on PDCCH (e.g., polarization-based coded signals), can be based on sequence-based signals, or can utilize a DRX WUS design (e.g., utilizing CDRX PDCCH in the current design). For the design of the UE group common indication for energy harvesting operations in the PDCCH, the WUS PDCCH received outside of DRX activity time (e.g., DCI format 2_6) can be the baseline design.
[0115] In some aspects, the baseline design can be modified to design the DCI for configuring energy harvesting operations, and the first DCI for simply configuring active operations can be different from the second DCI for configuring energy harvesting operations. In such aspects, additional bit fields can be added to the baseline design (e.g., a group common DCI, which can be flexible and have available bits for configuring energy harvesting operations) so that the network entity can indicate energy harvesting activity to UE 115-a. The first DCI for configuring active operations can be distinguished from the second DCI for configuring energy harvesting operations using RNTI or CORESET. For example, the network entity can send the first DCI to UE 115-a using the first RNTI or in the first CORESET, and the network entity can send the second DCI to UE 115-a using the second RNTI or in the second CORESET (e.g., where the content and meaning of the fields in the first DCI and the second DCI are different).
[0116] In other aspects, the baseline design can be modified to design the DCI for configuring energy harvesting operations and configuring active operations. That is, additional fields can be included in the DCI for configuring energy harvesting operations (e.g., because the DCI can be flexible, can have a variable size, and the network can define additional parameters or fields for configuring energy harvesting operations). In some examples, the configuration for energy harvesting can be included in the DCI. In other examples, the configuration for energy harvesting can be configured by the RRC (e.g., and not included in the DCI due to the limited DCI size shared by a group of UEs), and UE 115-a can use the configuration configured by the RRC to determine the energy harvesting operation. If the RRC is configured with a threshold number of configurations for energy harvesting operations, the DCI can include one or more bits to indicate which configuration UE 115-a can use for energy harvesting operations.
[0117] In some examples, the configuration for energy harvesting (e.g., energy harvesting for an energy harvesting task) can be accomplished using RRC or MAC-CE, and the DCI can activate the configuration. For example, the DCI can activate a configuration among many configurations indicated by RRC or MAC-CE, or activate a configuration indicated by RRC or MAC-CE (e.g., if RRC or MAC-CE indicates a single configuration). That is, multiple configurations can be signaled via RRC, one or more configurations can be downselected using MAC-CE, and a single configuration can be indicated in the DCI (e.g., WUSDCI). If a single configuration is signaled via RRC, or the configuration is downselected as a single configuration by MAC-CE, then once the DCI (e.g., WUS) is received, UE 115-a can adopt, implement, or use that configuration to perform energy harvesting operations. The configuration for energy harvesting can indicate whether UE 115-a is decoding data, performing energy harvesting, or both during the on-duty period, and the configuration for energy harvesting can indicate the technology used to perform energy harvesting or decoding data (e.g., as referenced). Figures 3A-3C and Figures 4A-4C (More detailed description follows).
[0118] The configuration for energy harvesting may include one or more configuration parameters indicating the frequency range for performing energy harvesting, allowing UE 115-a to adjust the energy harvesting circuitry configuration (e.g., RF tuning, etc.). The configuration for energy harvesting may also include parameters for UE 115-a when UE 115-a is configured to perform power splitting energy harvesting (e.g., as described herein, referenced by example). Figure 3B The power splitting factors described herein may also include one or more power splitting factors used when the UE 115-a is configured to perform time-split power harvesting (e.g., as referenced herein). Figure 3A The configuration parameters described herein include one or more configuration parameters for the timing of energy harvesting and the timing of data decoding. The configuration for energy harvesting may include, when the UE 115-a is configured to use a separate architecture for decoding data and performing energy harvesting (e.g., as described herein, referenced for example). Figure 3C The configuration (described) includes one or more configuration parameters for the timing of energy harvesting and the timing of data decoding. The configuration for energy harvesting may include one or more configuration parameters (e.g., filter or beam indication) for an analog or digital beamformer for use by the UE 115-a to perform energy harvesting. The configuration for energy harvesting may include the configuration of the energy harvesting signal, including the initial configuration of the waveform, sequence, or demodulation reference signal (DMRS) configuration.
[0119] In some respects, UE 115-a can support a first DCI for configuring active operation and a second DCI for configuring energy harvesting operation. That is, UE 115-a can expect to receive either the first or second DCI before the activation duration. UE 115-a can receive RRC signaling indicating the configuration for energy harvesting, and UE 115-a can receive MAC-CE indicating a downward selection of the configuration for energy harvesting. That is, the MAC-CE can indicate a subset of configurations available to UE 115-a from the configuration indicated in the RRC signaling.
[0120] If UE 115-a receives the first DCI (e.g., DCI format 2_6 without modification), UE 115-a can use one or more technologies supported by UE 115-a to determine the configuration for energy harvesting. In some cases, UE 115-a may receive RRC signaling or MAC-CE indicating the technology used by UE 115-a to determine the configuration for energy harvesting, or UE 115-a may otherwise identify the technology used to determine the configuration for energy harvesting.
[0121] In one example of a technique for determining the configuration for energy harvesting, UE 115-a may avoid performing energy harvesting (e.g., no energy harvesting is expected), and UE 115-a may decode data during the on-duration period (e.g., data is expected to persist throughout the on-duration period). In another example of a technique for determining the configuration for energy harvesting, UE 115-a may use a default energy harvesting configuration. In this example, a network entity or transmitting device (e.g., radio device 202-a) may define a default energy harvesting configuration. The default energy harvesting configuration may be the same as or different from the configuration used for energy harvesting when UE 115-a fails to decode DCI (e.g., WUS205). In yet another example of a technique for determining the configuration for energy harvesting, UE 115-a may use a configuration for energy harvesting indicated by MAC-CE or via RRC (e.g., when MAC-CE or RRC indicates a single configuration). That is, UE 115-a may assume an energy harvesting configuration after downselection via MAC-CE (e.g., assuming MAC-CE downselection is a single configuration).
[0122] If UE 115-a receives a second DCI (e.g., a modified DCI format 2_6, in which fields are defined or at least one bit is added for configuring energy harvesting), UE 115-a can use one or more technologies supported by UE 115-a to determine the configuration for energy harvesting. In some cases, UE 115-a may receive RRC signaling or MAC-CE indicating the technology used by UE 115-a to determine the configuration for energy harvesting, or UE 115-a may otherwise identify the technology used to determine the configuration for energy harvesting. For example, switching between technologies used to determine the configuration for energy harvesting may be configured by RRC or MAC-CE, or the second DCI may include a field indicating the use of an index to select a configuration in the configuration or to provide a new configuration (e.g., different from the configuration signaled via RRC or MAC-CE).
[0123] In one example of a technique for determining the configuration for energy harvesting, a network entity may instruct, and UE 115-a may receive, an index for the configuration of UE 115-a for energy harvesting (e.g., a configuration selected down through MAC-CE, or, if not selected down through MAC-CE, the configuration indicated in the RRC). In another example of a technique for determining the configuration for energy harvesting, a second DCI may indicate a new configuration different from the configuration indicated in the RRC or MAC-CE. In yet another example of a technique for determining the configuration for energy harvesting, a second DCI (e.g., new WUS reception) may indicate that a network entity is reconfiguring UE 115-a (e.g., changing the configuration at UE 115-a) for energy harvesting. For example, a second DCI may indicate that UE 115-a will use the configuration for energy harvesting indicated by MAC-CE or via RRC (e.g., when MAC-CE or RRC indicates a single configuration). Then, UE 115-a can use the configuration for energy harvesting indicated by MAC-CE or via RRC until UE 115-a receives another second DCI that changes the configuration for energy harvesting at UE 115-a.
[0124] The method disclosed herein can be associated with one or more advantages. For example, using WUS205 to instruct UE 115-a whether to collect energy, decode data, or both allows UE 115-a to dynamically determine whether to collect energy or decode data. Additionally, using WUS205 to perform the instruction allows UE 115-a to make the determination before the corresponding on-duration 225 (e.g., UE 115-a may make the determination without using any time during the on-duration). Additionally or alternatively, in examples where UE 115-a fails to receive WUS205, the method described herein allows UE 115-a to still be able to make a decision about whether to collect energy, decode data, or both.
[0125] Figure 3A , Figure 3B and Figure 3C Examples of architectures 300-a, 300-b, and 300-c supporting wireless power-on-demand (WOP) devices according to various aspects of this disclosure are illustrated. In some examples, architectures 300-a, 300-b, and 300-c can be implemented by various aspects of the wireless communication system 100. For example, architectures 300-a, 300-b, and 300-c may represent architectures at the UE 115 for decoding data and harvesting energy. Architectures 300-a, 300-b, and 300-c may represent three energy harvesting schemes. For example, architecture 300-a may correspond to a time-switching architecture, architecture 300-b may correspond to a power-split architecture, and architecture 300-c may correspond to a separate receiver architecture.
[0126] In some examples, radio frequency (RF) energy harvesting can have one or more characteristics. For example, an RF source can provide controlled or constant energy transfer over a distance from the harvester. Additionally, in a fixed RF energy harvesting network, the harvested energy can be predictable and relatively stable over time (e.g., within a threshold range) (e.g., due to the fixed distance between the source and the harvester). Using a random multipath fading channel model, the energy harvested at node j from transmitting node i for a single transmit antenna or port and a single receive antenna can be given as E. j =ηP i |g i-j | 2 T, where P i It could be the transmit power of node i, g i-jThis can be the channel coefficient of the link between node i and node j, T is the time allocated for energy harvesting, and η is the RF-to-DC (RF-to-DC) conversion efficiency. In some examples, the energy harvesting node may include: a microcontroller for processing data; an RF transceiver for sending or receiving information; an energy harvester including an RF antenna, impedance matching circuitry, a voltage converter, and capacitors to harvest energy from the RF signal and store it as usable charge; a power management module that determines whether to store the power obtained from the RF energy harvester or to use it immediately for information transmission; an energy storage device or battery; or any combination thereof.
[0127] Figure 3A A time-switching architecture can be described that enables network nodes (e.g., UE 115, base station 105) to switch between receiving or decoding information and harvesting energy. Architecture 300-a may include a transceiver 305-a (e.g., or receiver), a distribution component 310-a, an energy harvester 315-a, and an information decoder 320-a. The transceiver 305-a may be configured to receive signals from a wireless device (e.g., another UE 115, another base station 105). The distribution component 310-a may be configured to selectively couple the transceiver 305-a to either the energy harvester 315-a or the information decoder 320-a. In some examples, the distribution component 310-a may include one or more switches, diodes, transistors, or other switching components. The energy harvester 315-a may be configured to harvest energy from signals received by the transceiver 305-a when the energy harvester 315-a is coupled to the transceiver 305-a. The information decoder 320-a can be configured to decode data from signals received by the transceiver 305-a when the information decoder 320-a is coupled to the transceiver 305-a. In some examples, the energy harvested at the receiver j from the source i (e.g., a wireless device) can be determined as E. j =ηP i |g i-j | 2 αT, where 0 ≤ α ≤ 1, can be the proportion of time allocated for energy harvesting. In some examples, the data rate can be based on decoding and can be determined as... Where κ corresponds to the noise spectral density, W corresponds to the channel bandwidth, and 0≤1-α≤1 can be the proportion of time allocated for data reception and decoding. In some cases, this can be converted into multiple symbols or time slots within a duration or time period (e.g., 10 energy harvesting symbols and 4 data transmission symbols within a time period of 14 symbols (e.g., 1 time slot)).
[0128] Figure 3BA power splitting architecture can be described that enables network nodes (e.g., UE 115, base station 105) to split a signal into two streams (e.g., one stream for information decoder 320-b and another stream for energy harvester 315-b). Architecture 300-b may include a transceiver 305-b (e.g., or receiver), a distribution component 310-b, an energy harvester 315-b, and an information decoder 320-b. The transceiver 305-b may be configured to receive signals from a wireless device (e.g., another UE 115, another base station). The distribution component 310-b may be configured to couple the transceiver 305-b to the energy harvester 315-b and the information decoder 320-b. In some examples, the distribution component 310-b may include a splitter or divider (e.g., a variable power divider) or an example of a splitter or divider (e.g., a variable power divider). Energy harvester 315-b can be configured to harvest energy from signals received by transceiver 305-b, and information decoder 320-b can be configured to decode data from signals received by transceiver 305-b. In some examples, the energy harvested at receiver j from source i (e.g., a wireless device) can be determined as E. j =ηρP i |g i-j | 2 T, where 0 ≤ ρ ≤ 1, can be the proportion of power allocated for energy harvesting. In some examples, the data rate can be based on decoding and can be determined as... Where κ corresponds to the noise spectral density, W corresponds to the channel bandwidth, and 0≤1-ρ≤1 can be the proportion of power allocated for data reception and decoding.
[0129] Figure 3C A separate receiver architecture can be described, enabling network nodes (UE 115, base station 105) to use one receiver (e.g., transceiver 305-c) to harvest energy and another receiver (e.g., transceiver 305-d) to decode data. Architecture 300-c may include transceiver 305-c, transceiver 305-d, energy harvester 315-c, and information decoder 320-c. Transceiver 305-c may be configured to receive a first signal from a wireless device (e.g., another UE 115, another base station), and transceiver 305-d may be configured to receive a second signal from a wireless device. Energy harvester 315-c may be configured to harvest energy from the signal received by transceiver 305-c, and information decoder 320-c may be configured to decode data from the second signal received by transceiver 305-d.
[0130] Figure 4A , Figure 4B and Figure 4C Examples of communication schemes 400-a, 400-b, and 400-c supporting wake-up wirelessly powered devices according to various aspects of this disclosure are illustrated. In some examples, communication schemes 400-a, 400-b, and 400-c may be implemented by various aspects of wireless communication systems 100 or 200. For example, WUS 405, data 410, and energy 415 may be provided by reference... Figure 2 The wireless device described in reference 202-a Figure 1 The UE 115 described or referenced Figure 1 The base station 105 described transmits the data. Additionally, WUS 405, data 410, and energy 415 can be received by UE 115, as described in the reference. Figure 1 As described.
[0131] exist Figure 4A In this context, WUS 405 can instruct the decoding of data 410 or the harvesting of energy 415. For example, WUS 405-a can provide instruction 420-a to decode data 410-a during the first on-duration of DRX cycle 425-a. In some examples, decoding data 410-a may include UE 115-a monitoring a channel (e.g., a control channel) and decoding transmissions scheduled by that channel (e.g., shared channel transmissions). In some examples, UE 115-a may transition to an inactive state before the on-duration has fully elapsed, or may remain active after the on-duration has elapsed (e.g., if more data is scheduled to arrive after the on-duration has fully elapsed). Additionally, WUS 405-b can provide instruction 420-b to harvest energy 415-a during the second on-duration of DRX cycle 425-a.
[0132] exist Figure 4BIn this context, WUS 405 can instruct data decoding, energy harvesting, or simultaneous decoding of data and energy harvesting during at least a portion of the on-duration of DRX cycle 425-b. For example, WUS 405-c can provide instruction 420-c to decode data 410-b and harvest energy 415-b during a first on-duration of DRX cycle 425-b. WUS 405-d can provide instruction 420-d to harvest energy 415-c during a second on-duration of DRX cycle 425-b. In the example where UE 115 splits the power of the received signal into two streams (e.g., data 410-b, energy 415-b), WUS 405-c can have an initial value for the power split that UE 115 can use during one or more subsequent transmissions (e.g., reception at UE 115) within the active period (e.g., until a second instruction is received from the radio device or base station 105). In some examples, UE 115 can use the parameter 0≤ρ≤1 to represent the proportion of energy to be collected relative to the energy to be used for decoding. For example, the proportion of energy to be collected can be determined as ρ, and the proportion of energy to be used for decoding can be determined as 1-ρ.
[0133] exist Figure 4C In this context, WUS 405 can instruct data decoding, energy harvesting, or both during the first portion 440 of the on-duration of DRX cycle 425-c, and energy harvesting during the second portion 445 of the on-duration. For example, WUS 405-e can provide instruction 420-e to decode data 410-c during the first portion 440 of the first on-duration of DRX cycle 425-c, and to harvest energy 415-d during the second portion 445 of the first on-duration. WUS 405-f can provide instruction 420-f to harvest energy 415-e during the second on-duration of DRX cycle 425-c. When UE 115 performs a time handover (e.g., as referenced herein), Figure 3A In the described example, where UE 115 can divide the on-time into energy harvesting and data decoding, WUS 405-e can indicate the order of energy 415-d and data 410-c (e.g., which is in the first portion 440 and which is in the second portion 445), or can have partial time slots or multiple time slots for each (e.g., until a second indication is received from the radio device or base station 105). In some examples, UE 115 can use a parameter α to represent the proportion of the data duration over the entire on-time T. For example, in some examples, the first portion 440 can be determined as αT and the second portion 445 can be determined as (1-α)T.
[0134] In some examples (e.g., UE 115 uses a discrete architecture as described herein, such as references...) Figure 3C UE 115 may have different panels for energy harvesting and data decoding and reception. In some such examples, WUS 405-e may not include energy harvesting information (e.g., it may not indicate whether energy is harvested 415, data is decoded 410, or both). In other such examples, WUS 405-e may instruct UE 115 to use a time-switching scheme such that UE 115 will decode the data and then harvest energy. In such examples, UE 115 may harvest energy and decode data while transmitting data (e.g., in the first part 440), and may harvest energy while transmitting an energy signal (e.g., in the second part 445).
[0135] Figure 5 An example of a processing flow 500 supporting wake-up of a wirelessly powered device according to various aspects of this disclosure is illustrated. In some examples, processing flow 500 may be implemented by one or more aspects of wireless communication system 100 or 200. For example, UE 115-b may be as described in reference... Figure 1 The example of UE 115 described herein, and the wireless device 202-b may be as referenced Figure 2 The wireless device described in 202-a, as referenced Figure 1 The base station 105 described, or as referenced Figure 1 An example of UE 115 as described.
[0136] At point 505, radio device 202-b may send a wake-up message (e.g., WUS) to UE 115-b. This wake-up message includes an indicator of whether the on-duration of the DRX cycle is associated with energy harvesting from signals transmitted during the on-duration. The wake-up message may be sent in a specific time slot or symbol relative to the on-duration of the DRX cycle (e.g., several time slots or symbols preceding the on-duration). The wake-up message may be sent via a control channel or via a dedicated physical channel.
[0137] At 510, wireless device 202-b can send a signal to UE 115-b during the on duration based on a wake-up message.
[0138] At 515, UE 115-b can harvest energy from the signal. For example, UE 115-b can harvest energy from the signal by associating the duration of the DRX cycle on with the energy harvesting from the signal based on the indicator of the wake-up message.
[0139] At 520, UE 115-b can decode data from the signal. For example, UE 115-b can decode data based on an indicator in a wake-up message that indicates the duration of the DRX cycle on is not associated with harvesting energy from the signal (e.g., in an example where the wake-up message indicates harvesting energy or decoding data). Additionally or alternatively, at 520, UE 115-b can suppress data decoding from the signal based on an indicator in a wake-up message indicating that the duration of the DRX cycle on is associated with harvesting energy from the signal.
[0140] In some examples, the wake-up message indicator may instruct the decoding of data from the signal and the harvesting of energy from the signal during the on-duty period (e.g., the signal may notify UE 115-b to perform steps 515 and 520). In some such examples, UE 115-b may harvest energy from the signal based on the wake-up message indicator instructing it to harvest energy, and may decode data from the signal based on the wake-up message indicator instructing it to decode data from the signal. In some examples, energy harvesting and data decoding may occur concurrently during at least a portion of the on-duty period (e.g., as referenced). Figure 4B (As described). In some such examples, UE 115-b may receive in the wake-up message or other signaling a parameter (e.g., ρ, 1-ρ) indicating the proportion of power allocated for energy harvesting during at least that portion of the duration. In some examples, energy harvesting occurs during a first portion of the on-duration, and data decoding occurs during a second portion of the on-duration. In some such examples, the first and second portions may not overlap in time. Additionally, in some such examples, UE 115-b may receive in the wake-up message a parameter (e.g., α, 1-α) indicating a first duration (e.g., total length) of the first portion, a second duration (e.g., total length) of the second portion, or both.
[0141] In some examples, UE 115-b may determine that UE 115-b failed to receive or decode a second wake-up message during a second on-duration period of a second DRX cycle. In some such examples, UE 115-b may, based on the determination that UE 115-b failed to receive or decode a second wake-up message, harvest energy from a second signal during the second on-duration period, decode data from the second signal during the second on-duration period, or both. In some examples, UE 115-b may determine whether to harvest energy from a second signal, decode data from a second signal, or both, based on a first parameter (e.g., p1) associated with whether UE 115-b wants to activate during the second on-duration period, a second parameter (e.g., p2) associated with whether to harvest energy, a third parameter (e.g., p3) associated with whether to decode data, a fourth parameter (e.g., p4) associated with whether to harvest energy and decode data, or any combination thereof. In some examples, the first parameter corresponds to a first probability, the second parameter corresponds to a second probability, the third parameter corresponds to a third probability, and the fourth parameter corresponds to a fourth probability. Additionally, in some examples, UE 115-b can perform a random selection based on a probability distribution to determine whether to remain deactivated during the on duration, harvest energy during the on duration, decode data during the on duration, or harvest energy and decode data during the on duration. In some such examples, the probability distribution may include a first probability, a second probability, a third probability, and a fourth probability. In some examples, the probability distribution may be associated with a pseudo-random generator having a seed identified by radio device 202-b and UE 115-b. Therefore, both radio device 202-b and UE 115-b can identify whether UE 115-b should be activated and whether UE 115-b should decode data, harvest energy, or both.

The communication manager 820 may be an example of a communication manager 620, a communication manager 720, or aspects thereof as described herein. The communication manager 820 or its various components may be examples of parts for performing various aspects of wake-up wirelessly powered devices as described herein. For example, the communication manager 820 may include a wake-up message receiver 825, a signal receiver 830, a data decoder 835, an energy harvester 840, a WUS fault determination component 845, a parameter receiver 850, a signal determination component 855, a control message receiver 860, or any combination thereof. Each of these components may communicate with each other directly or indirectly (e.g., via one or more buses).
[0157] Additionally or alternatively, the communication manager 820 may support wireless communication at the UE according to the examples disclosed herein. The wake-up message receiver 825 may be configured or otherwise supported for receiving a wake-up message including an indicator of whether the on-duration of a discontinuous reception period is associated with energy harvesting from a signal transmitted during that on-duration. The signal receiver 830 may be configured or otherwise supported for receiving a signal during the on-duration based on the wake-up message.
[0158] In some examples, the data decoder 835 may be configured or otherwise supported for decoding data from a signal based on an indicator indicating that the on-time duration of a discontinuous reception cycle is not associated with energy harvesting from the signal.
[0159] In some examples, the energy harvester 840 may be configured or otherwise supported for a component that harvests energy from a signal when an indicator based on a wake-up message indicates that at least a portion of a discontinuous reception period is associated with harvesting energy from the signal. In some examples, the data decoder 835 may be configured or otherwise supported for a component that suppresses the decoding of data from a signal when an indicator based on a wake-up message indicates that the on-duration of a discontinuous reception period is associated with harvesting energy from the signal.

[0162] In some examples, energy acquisition occurs during a first portion of the on-time duration, and data decoding occurs during a second portion of the on-time duration, with the first and second portions not overlapping in time. In some examples, to support receiving wake-up messages, the parameter receiver 850 may be configured or otherwise supported to support components for receiving parameters in the wake-up message, which indicate a first duration of the first portion, a second duration of the second portion, the order of the first and second portions, the gap between the first and second durations, or a combination thereof.

[0167] In some examples, one or more control messages indicating one or more configurations include at least one of the following: a radio resource control message indicating a set of configurations associated with harvesting energy from signals transmitted during the on-duration period, or a media access control control element indicating a subset of configurations associated with harvesting energy from signals transmitted during the on-duration period from the set of configurations.
[0168] In some examples, the indicator in the first downlink control information indicates a single configuration from a subset of configurations associated with harvesting energy from signals transmitted during the on-duration period. In some examples, the subset of configurations indicated in the media access control element includes a single configuration, and the indicator in the first downlink control information defaults to indicating the single configuration associated with harvesting energy from signals transmitted during the on-duration period. In some examples, the wake-up message receiver 825 may be configured or otherwise supported for receiving second downlink control information indicating a configuration different from the configuration in the subset associated with harvesting energy from signals transmitted during the second on-duration period of the second discontinuous reception cycle.
[0169] In some examples, one or more configurations include a configuration for harvesting energy in one or more frequency ranges during the on-duration, a configuration of a proportion of power allocated for harvesting energy during the on-duration, a configuration of a first portion of the on-duration in which energy is harvested and a second portion of the on-duration in which data is decoded, a configuration of a filter or beam for harvesting energy during the on-duration, a configuration of a signal from which energy is harvested, or a combination thereof.

[0173] I / O controller 910 can manage input and output signals for device 905. I / O controller 910 can also manage peripheral devices not integrated into device 905. In some cases, I / O controller 910 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 910 may utilize an operating system, such as or another known operating system.

Code 935 may be stored in a non-transitory computer-readable medium, such as system memory or another type of memory. In some cases, code 935 may not be directly executed by processor 940, but may instead cause a computer (e.g., when compiled and executed) to perform the functions described herein. In some cases, memory 930 may, in particular, include a basic I / O system (BIOS) that controls basic hardware or software operations, such as interaction with peripheral components or devices.
