FIELD OF THE DISCLOSURE

[0002] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for performing actions for transmissions of a device capable of energy harvesting.

BACKGROUND

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC- FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3 GPP).

[0004] A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the base station to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the base station.

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple -input multiple -output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

[0021] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. [0022] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0023] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

[0024] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as a BS 110a, a BS 110b, a BS 110c, and a BS 1 lOd), a user equipment (UE) 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other network entities. A base station 110 is an entity that communicates with UEs 120. A base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station 110 and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

[0025] A base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown in Fig. 1, the BS 110a may be a macro base station for a macro cell 102a, the BS 110b may be a pico base station for a pico cell 102b, and the BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

[0026] In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station 110 that is mobile (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected to one another and/or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

[0027] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station 110 or a UE 120) and send a transmission of the data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the BS 1 lOd (e.g., a relay base station) may communicate with the BS 110a (e.g., a macro base station) and the UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A base station 110 that relays communications may be referred to as a relay station, a relay base station, a relay, or the like. [0028] The wireless network 100 may be a heterogeneous network that includes base stations 110 of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0. 1 to 2 watts). [0029] A network controller 130 may couple to or communicate with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via a backhaul communication link. The base stations 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

[0030] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

[0031] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Intemet-of-Things (loT) devices, and/or may be implemented as NB-IoT (narrowband loT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

[0032] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. [0033] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to- vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

[0034] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

[0035] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4- 1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0036] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

[0037] In some aspects, a first device (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may determine a first transmission between the first device and a second device, wherein the first device is a low power device associated with an energy harvesting capability; determine a second transmission between the first device and the second device, wherein the second transmission and the first transmission are separated by a quantity of symbols that satisfies a threshold value; and perform an action on one or more of the first transmission or the second transmission based at least in part on a priority associated with the first transmission or the second transmission, a cost associated with the first transmission or the second transmission, or a battery status associated with the first device. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0038] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

[0039] Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The base station 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T> 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1).

[0040] At the base station 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple -output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, fdter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t.

[0041] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the base station 110 and/or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., fdter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0042] The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0043] One or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2. [0044] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RS SI, RSRQ, and/or CQI) from the controller/processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and/or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller/processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 5-8). [0045] At the base station 110, the uplink signals from UE 120 and/or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller/processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and/or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller/processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 5-8).

[0046] The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with performing actions for transmissions of a device capable of energy harvesting, as described in more detail elsewhere herein. In some aspects, the first device described herein is the UE 120, is included in the UE 120, or includes one or more components of the UE 120 shown in Fig. 2. In some aspects, the second device described herein is the base station 110, is included in the base station 110, or includes one or more components of the base station 110 shown in Fig. 2. For example, the controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other componcnt(s) of Fig. 2 may perform or direct operations of, for example, process 700 of Fig. 7, and/or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some examples, the memory 242 and/or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 700 of Fig. 7, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

[0047] In some aspects, a first device (e.g., UE 120) includes means for determining a first transmission between the first device and a second device, wherein the first device is a low power device associated with an energy harvesting capability; means for determining a second transmission between the first device and the second device, wherein the second transmission and the first transmission are separated by a quantity of symbols that satisfies a threshold value; and/or means for performing an action on one or more of the first transmission or the second transmission based at least in part on a priority associated with the first transmission or the second transmission, a cost associated with the first transmission or the second transmission, or a battery status associated with the first device. In some aspects, the means for the first device to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

[0048] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of the controller/processor 280. [0049] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

[0050] Harvesting radio frequency (RF) energy may be used to perform some tasks at a device (e.g., a UE, a wearable device, a smart watch, a low power device), such as data decoding, filter operation, data reception, data encoding, and/or data transmission. A purpose of RF energy harvesting may not be to charge a battery of the device in full, but rather to charge the battery of the device (or to use a dedicated battery for energy harvesting) such that some tasks may be performed using the harvested energy. These tasks may be performed based at least in part on an accumulation of harvested energy over a period of time. The harvested energy may be derived from RF signals transmitted in a network. The device may interact with the network using the harvested energy.

[0051] RF energy harvesting may be useful in loT cases. For example, RF energy harvesting may lead to a longer battery lifespan of an loT device with a battery. As another example, RF energy harvesting may lead to a battery-less loT device, such as a medical sensor or an implanted sensor.

[0052] An amount of energy that may be harvested from RF signals may be based at least in part a signal frequency, a signal source, a distance traveled by the RF signals, a Tx power associated with the RF signals, and/or an Rx power associated with the RF signals. The signal frequency may be associated with a very high frequency (VHF) or an ultra-high frequency (UHF). The signal source may be a tower or another device, such as a UE.

[0053] Energy harvesting may be derived from various sources, such as solar, vibration, thermal, and/or RF. Energy harvesting from a solar source may use photovoltaic cells, and may provide a relatively high power density, but requires exposure to light (not implantable).

Energy harvesting from a vibration source may use piezoelectric, electrostatic, and/or electromagnetic techniques, and may be implantable, but may suffer from material physical limitations. Energy harvesting from a thermal source may use a thermoelectric or pyroelectric techniques and may provide a relatively high power density and be implantable, but may produce excess heat. Energy harvesting from RF may use an antenna, and may be implantable, but may provide a relatively low power density where an efficiency is inversely proportional to a distance.

[0054] Fig. 3 is a diagram illustrating an example 300 of an RF energy harvesting system, in accordance with the present disclosure.

[0055] As shown in Fig. 3, an RF generator, acting as an RF source, may generate an RF signal. The RF generator may transmit, via a Tx antenna, the RF signal. The RF signal may be transmitted over a transmission space, and the RF signal may be received at an Rx antenna of a device. The RF signal may be directed to a wireless energy harvesting circuit of the device. The wireless energy harvesting circuit may include an impedance matching network and a rectifier/voltage multiplier, which may be responsible for converting the RF signal to power (e.g., direct current (DC) power). A power management system may be responsible for storing the power, and providing the power to application(s) of the device as needed.

[0056] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3.

[0057] Fig. 4 is a diagram illustrating an example 400 of energy harvesting schemes, in accordance with the present disclosure. [0058] As shown by reference number 402, a separated receiver architecture may be used for energy harvesting. An energy harvester of a device may receive RF signals from a first set of antennas. An information receiver of a device may receive RF signals from a second set of antennas. The energy harvester may function in a simultaneous manner with the information receiver, and received RF signals may be separate for the energy harvester and the information receiver.

[0059] As shown by reference number 404, a time switching architecture may be used for energy harvesting. The device may switch between the energy harvester and the information receiver using time switching, with a common antenna shared between the energy harvester and the information receiver. In other words, all RF signals received at the antenna may be directed to the energy harvester when a path is switched to be directed to the energy harvester. On the other hand, all RF signals received at the antenna may be directed to the information receiver when a path is switched to be directed to the information receiver.

[0060] As shown by reference number 406, a power splitting architecture may be used for energy harvesting. The common antenna between the energy harvester and the information receiver may receive RF signals, and the received RF signals may be split into two streams for the energy harvester and the information receiver. In other words, a power of the received RF signals may be split between the energy harvester and the information receiver.

[0061] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4.

[0062] A device, such as an energy harvesting node, may harvest energy from a source of harvesting such as solar, vibration, thermal, RF, etc. The device may be an loT device, a wearable device, or a UE associated with limited batter and power capabilities. The device may have hardware limits on transmissions or performing transmissions within an interval of time (e.g., consecutive transmissions within a relatively short period of time). Thus, consecutive data transmissions and/or data receptions within the interval of time may not be possible due to the hardware limits associated with the device using the harvested energy.

[0063] Further, data receptions and data transmissions may be associated with costs (e.g., power costs) per resource block or per resource element. For encoding data associated with the data transmissions, the costs may be a function of an MCS and a transport block size (TBS). For decoding data associated with the data receptions, the costs may be a function of a decoder number iteration, the MCS, and/or the TBS. energy.

[0064] In various aspects of techniques and apparatuses described herein, a first device may determine a first transmission between the first device and a second device. The first device may be a low power device associated with an energy harvesting capability. The first device may determine a second transmission between the first device and the second device. The second transmission and the first transmission may be separated by a quantity of symbols that satisfies a threshold value. The first device may perform an action on one or more of the first transmission or the second transmission based at least in part on a priority associated with the first transmission or the second transmission, a cost associated with the first transmission or the second transmission, or a battery status associated with the first device. In some aspects, the action may involve dropping the first transmission or the second transmission based at least in part on the priority associated with the first transmission or the second transmission, the cost associated with the first transmission or the second transmission, or the battery status associated with the first device. In some aspects, the action may involve multiplexing the first transmission and the second transmission to form a multiplexed transmission, and transmitting, to the second device, the multiplexed transmission in a first occasion associated with the first transmission or a second occasion associated with the second transmission.

[0065] In some aspects, the first device may perform the dropping or the multiplexing for two consecutive transmissions or tasks (e.g., data transmissions and/or data receptions) that occur within an interval of time. The interval of time may be a relatively short period of time, and may correspond to the quantity of symbols that satisfies the threshold value. The first device may perform the dropping or the multiplexing in accordance with a set of rules, which may be defined due to hardware limits associated with the device. The set of rules may serve to accommodate the hardware limits associated with the first device, where the hardware limits may be due to battery and power capabilities of the first device. The battery and power capabilities of the first device may be less than normal UEs, since the first device may use harvested energy to perform certain data transmissions and receptions.

[0066] Fig. 5 is a diagram illustrating an example 500 associated with performing actions for transmissions of a device capable of energy harvesting, in accordance with the present disclosure. As shown in Fig. 5, example 500 includes communication between a first device (e.g., UE 120a) and a second device (e.g., base station 110 or UE 120e). In some aspects, the first device and the second device may be included in a wireless network, such as wireless network 100.

[0067] As shown by reference number 502, the first device may determine a first transmission between the first device and the second device. The first transmission may be a first downlink transmission, a first uplink transmission, or a first sidelink transmission.

[0068] In some aspects, the first device may be a low power device associated with an energy harvesting capability. In some aspects, the first device may be a first loT device, a first wearable device, or a first UE. In some aspects, the second device may be a base station, a second loT device, a second wearable device, or a second UE. [0069] As shown by reference number 504, the first device may determine a second transmission between the first device and the second device. The second transmission may be a second downlink transmission, a second uplink transmission, or a second sidelink transmission. The second transmission and the first transmission may be separated by a quantity of symbols that satisfies a threshold value. The threshold value may be based at least in part on radio resource control (RRC) signaling or via a medium access control element (MAC-CE).

[0070] In some aspects, the first transmission may be a first physical downlink shared channel (PDSCH) transmission, and the second transmission may be a second PDSCH transmission. In some aspects, the first transmission may be a first physical uplink shared channel (PUSCH) transmission, and the second transmission is a second PUSCH transmission. In some aspects, the first transmission may be a PDSCH transmission, and the second transmission may be a PUSCH transmission or a physical uplink control channel (PUCCH) transmission. In some aspects, the first transmission may be a PUSCH transmission, and the second transmission may be a PUCCH transmission. In some aspects, the first transmission may be a PUCCH transmission, and the second transmission may be a PUSCH transmission. In some aspects, the first transmission may be a first physical sidelink shared channel (PSSCH) transmission, and the second transmission may be a second PSSCH transmission.

[0071] As shown by reference number 506, the first device may perform an action on the first transmission and/or the second transmission based at least in part on a priority associated with the first transmission or the second transmission, a cost associated with the first transmission or the second transmission, and/or a battery status associated with the first device. The first device may perform the action using a set of rules, which may be defined based at least in part on priorities associated with transmissions, costs associated with transmissions, and/or battery statuses associated with devices. In some aspects, when performing the action, the first device may drop the first transmission or the second transmission based at least in part on the priority associated with the first transmission or the second transmission, the cost associated with the first transmission or the second transmission, or the battery status associated with the first device. In some aspects, the first device may perform the action based at least in part on the battery status associated with the first device and a predicted energy harvesting at the first device, where the battery status may indicate a remaining battery level of the first device.

[0072] In some aspects, when performing the action, the first device may multiplex the first transmission and the second transmission to form a multiplexed transmission, and transmit, to the second device, the multiplexed transmission in a first occasion associated with the first transmission or a second occasion associated with the second transmission. The first occasion or the second occasion may correspond to a PUSCH occasion/allocation. For example, the multiplexed transmission may be transmitted in either the first occasion or the second occasion based at least in part on an availability of energy, or based at least in part on an indication to transmit the multiplexed transmission in one of the first occasion or the second occasion. The multiplexed transmission may be transmitted in either the first occasion or the second occasion when both data (e.g., both the first transmission and the second transmission) is ready to be transmitted.

[0073] In some aspects, when performing the action, the first device may modify a power configuration (e.g., reduce a transmission power) of the first transmission and/or the second transmission. For example, the first device may reduce a transmission power of the first transmission, so that the first device is about to transmit both the first transmission and the second transmission without dropping one of the first transmission or the second transmission. In some aspects, the first device may transmit both the first transmission and the second transmission without dropping or multiplexing the first transmission and/or the second transmission, based at least in part on a UE capability. The first device may not perform the dropping or multiplexing, but the first device may modify the power configuration of the first transmission and/or the second transmission in order to transmit both the first transmission and the second transmission.

[0074] In some aspects, the cost associated with the first transmission or the second transmission may include a decoding cost, or the cost associated with the first transmission or the second transmission may include an encoding cost and a transmission cost. The cost associated with the first transmission or the second transmission may be based at least in part on an MCS, a TBS, or a quantity of resource elements. In some aspects, the first device may transmit, to the second device, capability signaling that indicates costs per MCS and per TBS, where the costs may include decoding costs and encoding costs.

[0075] In some aspects, the first device may indicate costs, such as the decoding costs and the encoding costs, for each MCS, TBS, and in a case of decoding, a number of iterations. The decoding costs may be associated with data receptions (or downlink transmissions), and the encoding costs may be associated with data transmissions (or uplink transmissions). The first device may indicate the costs per MCS, TBS, resource block, and/or resource element as part of the capability signaling or an initial signaling between the first device and the second device. The uplink transmissions may be associated with a transmission power costs in addition to the encoding cost. Values associated with the costs may be predefined, such that each parameter combination cost may be indicated by the first device to the second device. The costs associated with encoding/decoding may be approximate costs, and the costs may be used for dropping or multiplexing consecutive transmissions.

[0076] In some aspects, the first device may partially or fully harvest energy associated with the first transmission based at least in part on the energy harvesting capability of the first device. The energy harvesting capability may include a radio frequency or wireless energy harvesting capability. The first device may transmit the second transmission based at least in part on the energy partially or fully harvested from the first transmission.

[0077] In some aspects, the first device may receive the first downlink transmission and the second downlink transmission, from two separated or same semi-persistent scheduling (SPS), or between an SPS and a dynamic grant (DG). The first downlink transmission may be associated with the first PDSCH transmission and the second downlink transmission may be associated with the second PDSCH transmission. The first downlink transmission and the second downlink transmission may be separated by X symbols, where X satisfies a threshold (e.g., X is less than the threshold). A value of A may be predefined or may be configured via RRC signaling or via a MAC-CE.

[0078] In some aspects, the first device that is receiving the first downlink transmission and the second downlink transmission from the two separated or same SPS or between the SPS and the DG, separated by the X symbols, may drop the first downlink transmission or the second downlink transmission (e.g., the SPS or the DG) based at least in part on a priority of the first downlink transmission versus a priority of the second downlink transmission.

[0079] In some aspects, the first device that is receiving the first downlink transmission and the second downlink transmission from the two separated or same SPS or between the SPS and the DG, separated by the X symbols, may drop the first downlink transmission or the second downlink transmission (e.g., the SPS or the DG) based at least in part on a decoding cost associated with the first downlink transmission and the second downlink transmission, where the decoding cost may be based at least in part on an MCS, a TBS, and/or a number of resource elements. The first device may determine the decoding cost associated with the first downlink transmission and the second downlink transmission, and the UE may drop the first downlink transmission or the second downlink transmission based at least in part on the respective decoding costs.

[0080] In some aspects, the first device may have an RF/wireless energy harvesting capability. The first device may partially (e.g., via power splitting energy harvesting) or fully harvest energy of the first downlink transmission or the second downlink transmission, depending on which of the first downlink transmission or the second downlink transmission is dropped.

[0081] In some aspects, the second device may receive, from the first device, an indication of the battery status of the first device and the predicted energy harvesting at the first device. The second device may multiplex both the first downlink transmission and the second downlink transmission into a first downlink channel occasion (e.g., PDSCH occasion) or a second downlink channel occasion, based at least in part on the indication received from the first device. The second device may multiplex both the first downlink transmission and the second downlink transmission, as opposed to dropping either the first downlink transmission or the second downlink transmission based at least in part on the priority or the decoding cost. The second device may use a relatively small fixed-size TBS with energy harvesting devices, and multiplexing may be feasible for such low size TBSs.

[0082] In some aspects, the first device may generate the first uplink transmission and the second uplink transmission. The first uplink transmission may be the first PUSCH transmission and the second uplink transmission may be the second PUSCH transmission. The first uplink transmission and the second uplink transmission may be separated by X symbols, where X satisfies the threshold (e.g., X is less than the threshold). The first device may drop either the first uplink transmission or the second uplink transmission based at least in part on a priority of the first uplink transmission versus a priority of the second uplink transmission. Alternatively, the first device may drop either the first uplink transmission or the second uplink transmission based at least in part on a cost associated with the first uplink transmission and the second uplink transmission. The cost may include an encoding cost and a transmission cost.

[0083] In some aspects, the first device may multiplex both the first uplink transmission and the second uplink transmission into a first uplink channel occasion (e.g., PUSCH occasion) or a second uplink channel occasion. The first device may multiplex both the first uplink transmission and the second uplink transmission, as opposed to dropping either the first uplink transmission or the second uplink transmission based at least in part on the priority or the decoding cost. The first device may multiplex both the first uplink transmission and the second uplink transmission based at least in part on an assumption that the second device has received the indication from the first device, where the indication indicates the battery status of the first device and the predicted energy harvesting at the first device.

[0084] In some aspects, the first uplink transmission may be the PUSCH transmission, and the second uplink transmission may be the PUCCH transmission. The first uplink transmission and the second uplink transmission may be separated by X symbols, where X satisfies the threshold (e.g., X is less than the threshold). In some aspects, the first device that is performing the first uplink transmission and the second uplink transmission may drop the first uplink transmission and keep the second uplink transmission, based at least in part on a priority of the first uplink transmission versus a priority of the second uplink transmission, or based at least in part on a power or battery level of the first device. In some aspects, the first device that is performing the first uplink transmission and the second uplink transmission may drop the second uplink transmission and keep the first uplink transmission, based at least in part on the priority of the first uplink transmission versus the priority of the second uplink transmission, or based at least in part on a presence of a sufficient power at a battery of the first device.

[0085] In some aspects, the first uplink transmission may be the PUCCH transmission, and the second uplink transmission may be the PUSCH transmission. In some aspects, the first device that is performing the first uplink transmission and the second uplink transmission may drop the second uplink transmission and keep the first uplink transmission, based at least in part on the priority of the first uplink transmission versus the priority of the second uplink transmission, or based at least in part on the power or battery level of the first device. In some aspects, the first device that is performing the first uplink transmission and the second uplink transmission may drop the first uplink transmission and keep the second uplink transmission, based at least in part on the priority of the first uplink transmission versus the priority of the second uplink transmission, or based at least in part on the presence of the sufficient power at the battery of the first device.

[0086] In some aspects, the first device may multiplex both the first uplink transmission and the second uplink transmission into an uplink channel occasion (e.g., PUSCH occasion), since the uplink channel occasion may be associated with an increased number of resource blocks or a larger resource block allocation as compared to other types of channel occasions. The first device may multiplex both the first uplink transmission and the second uplink transmission, as opposed to dropping either the first uplink transmission or the second uplink transmission based at least in part on the priority or the decoding cost. The first device may multiplex both the first uplink transmission and the second uplink transmission based at least in part on an assumption that the second device has received the indication from the first device, where the indication indicates the battery status of the first device and the predicted energy harvesting at the first device.

[0087] In some aspects, the first device may receive a downlink transmission, and the first device may expect to transmit an uplink transmission based at least in part on the downlink transmission. The downlink transmission and the uplink transmission may be separated by X symbols, where X satisfies the threshold (e.g., X is less than the threshold). The downlink transmission may be the PDSCH transmission, and the uplink transmission may be the PUCCH/PUSCH transmission. The first device that is receiving the downlink transmission and is expected to transmit the uplink transmission after the X symbols may drop either the downlink transmission or the uplink transmission. In some aspects, the first device may drop either the downlink transmission or the uplink transmission based at least in part on a priority of the downlink transmission versus a priority of the uplink transmission. In some aspects, the first device may drop either the downlink transmission or the uplink transmission based at least in part on which of the downlink transmission or the uplink transmission consumes a lower energy. In some aspects, the first device may drop either the downlink transmission or the uplink transmission based at least in part on which of the downlink transmission or the uplink transmission are sufficient to be performed (e.g., decoding for the PDSCH transmission or encoding for the PUCCH/PUSCH transmission). [0088] In some aspects, the first device may have the RF/wireless energy harvesting capability. The first device may partially (e.g., via power splitting energy harvesting) or fully harvest energy of the downlink transmission and then perform the uplink transmission using harvested energy.

[0089] In some aspects, the first device may perform the first sidelink transmission and the second sidelink transmission. The first sidelink transmission may be the first PSSCH transmission, and the second sidelink transmission may be the second PSSCH transmission. The first sidelink transmission and the second sidelink transmission may be separated by X symbols, where X satisfies the threshold (e.g., X is less than the threshold). The first sidelink transmission and the second sidelink transmission may be associated with two occasions of a PSSCH on a sidelink. The first device may transmit the first sidelink transmission and transmit the second sidelink transmission, the first device may receive the first sidelink transmission and receive the second sidelink transmission, the first device may transmit the first sidelink transmission and receive the second sidelink transmission, or the first device may receive the first sidelink transmission and transmit the second sidelink transmission. In some aspects, the first device may multiplex both the first sidelink transmission and the second sidelink transmission, or drop either the first sidelink transmission or the second sidelink transmission, based at least in part on the battery status of the first device and an ability to transmit/receive sidelink transmissions. The first device may not perform multiplexing or dropping based at least in part on a priority of the first sidelink transmission versus a priority of the second sidelink transmission, since the first device may be unable to determine priorities beforehand in sidelink.

[0090] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.

[0091] Fig. 6 is a diagram illustrating an example 600 associated with performing actions for transmissions of a device capable of energy harvesting, in accordance with the present disclosure.

The PUSCH transmission may occur earlier in time as compared to the PUCCH transmission. In some aspects, the first device may drop the PUCCH transmission and keep the PUSCH transmission based at least in part on the priority or a presence of a sufficient power at a battery of the first device. Alternatively, the first device may multiplex the PUCCH transmission and the PUSCH transmission into a PUSCH occasion, since the PUSCH occasion may be associated with more resource blocks or a larger resource block allocation as compared to a PUCCH occasion.

[0095] As shown by reference number 608, a first device (e.g., an energy harvesting device) that is transmitting a PUCCH transmission and a PUSCH transmission, which are separated by X symbols where X is less than a threshold, may drop the PUSCH transmission and keep the PUCCH transmission based at least in part on a priority or a remaining power/battery level.

The first device may drop either the PDSCH transmission or the PUCCH/PUSCH transmission based at least in part on a priority of each transmission, which transmission consumes less energy, or which transmission is sufficient to be performed.

[0097] As shown by reference number 612, a first device (e.g., an energy harvesting device) that is performing a first PSSCH transmission and a second PSSCH transmission, which are separated by X symbols where X is less than a threshold, may drop or multiplex the first PSSCH transmission and/or the second PSSCH transmission based at least in part on a battery status of the first device and an ability to transmit/receive side link transmissions.

[0098] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.

[0099] Fig. 7 is a diagram illustrating an example process 700 performed, for example, by a first device, in accordance with the present disclosure. Example process 700 is an example where the first device (e.g., UE 120) performs operations associated with performing actions for transmissions of a device capable of energy harvesting.

[0100] As shown in Fig. 7, in some aspects, process 700 may include determining a first transmission between the first device and a second device, wherein the first device is a low power device associated with an energy harvesting capability (block 710). For example, the first device (e.g., using communication manager 140 and/or determination component 808, depicted in Fig. 8) may determine a first transmission between the first device and a second device, wherein the first device is a low power device associated with an energy harvesting capability, as described above in connection with Figs. 5-6.

[0101] As further shown in Fig. 7, in some aspects, process 700 may include determining a second transmission between the first device and the second device, wherein the second transmission and the first transmission are separated by a quantity of symbols that satisfies a threshold value (block 720). For example, the first device (e.g., using communication manager 140 and/or determination component 808, depicted in Fig. 8) may determine a second transmission between the first device and the second device, wherein the second transmission and the first transmission are separated by a quantity of symbols that satisfies a threshold value, as described above in connection with Figs. 5-6.

[0102] As further shown in Fig. 7, in some aspects, process 700 may include performing an action on one or more of the first transmission or the second transmission based at least in part on a priority associated with the first transmission or the second transmission, a cost associated with the first transmission or the second transmission, or a battery status associated with the first device (block 730).
