LOW-POWER WAKEUP SIGNAL MONITORINGFIELD OF THE DISCLOSURE
[0001] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with low-power wakeup signal monitoring. INTRODUCTION
[0002] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level.
[0003] An example telecommunication standard is New Radio (NR) . NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . NR (and other RATs beyond NR) may be designed to better support enhanced mobile broadband (eMBB) access, Internet of things (IoT) networks or reduced capability device deployments, and ultra-reliable low latency communication (URLLC) applications. To support these verticals, NR systems may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to-everything (CV2X) communication) , multiple-subscriber implementations, high-precision positioning, and / or radio frequency (RF) sensing, among other examples. As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases.
[0004] Communications (e.g., transmission and / or reception of signals) between entities (e.g., between a user equipment (UE) and a network node) may consume some amount of power. For example, a UE may consume a lower amount of power while in a low power state (such as while not connected to a network or while waiting for paging from the network) , and may consume a higher amount of power while in a full power state (such as while actively communicating with a network node or while monitoring for control information from the network) . Certain components of the UE may consume a significant amount of power. For example, a radio of the UE, which may support bidirectional communication (such as both transmission and reception) , multi-layer communication, or larger bandwidths (such as a communication bandwidth of the UE) , may consume power while active, such as in the course of communicating or monitoring for control information.SUMMARY

[0026] Various aspects of the present disclosure are described hereinafter with reference to the accompanying drawings. However, aspects of the present disclosure may be embodied in many different forms. The present disclosure is not limited to any specific aspect illustrated by or described with reference to an accompanying drawing or otherwise presented in 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. The scope of the disclosure covers any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using various combinations or quantities of the aspects set forth herein. In addition, the scope of the disclosure covers an apparatus having, or a method that is practiced using, other structures and / or functionalities in addition to or other than the structures and / or functionalities with which various aspects of the disclosure set forth herein may be practiced. Any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
[0027] Several aspects of telecommunication systems will now be presented with reference to various methods, operations, apparatuses, and techniques. These methods, operations, 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, or algorithms (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0028] To achieve power savings, a user equipment (UE) may include or be associated with a second, low-power wakeup radio (LP-WUR) in addition to a main radio. Relative to a non-LP-WUR (e.g., the main radio) , the LP-WUR may have reduced power consumption. For example, the LP-WUR may be configured with a reduced bandwidth, reduced processing capabilities, reduced hardware complexity, simplified architecture, or other reduced capabilities, relative to a main radio, which facilitate operation with reduced power consumption. The LP-WUR may facilitate indication, from the network, for the UE to exit a low power state, such as by waking up the main radio. For example, while the main radio is in a low power state, the LP-WUR may receive a signal referred to as a low-power wakeup signal (LP-WUS) , may trigger the main radio to exit the low power state, and may trigger the UE to transfer from an idle mode to an active mode to receive control channel (e.g., physical downlink control channel (PDCCH) ) for paging. In another example, when a UE is operating in a connected mode, the LP-WUS may trigger control channel monitoring (e.g., UE PDCCH monitoring) for data scheduling.
[0029] In some examples, the UE may not support LP-WUS reception on all frequency bands supported by the UE for data communication. For example, the UE may support LP-WUS reception on a subset of frequency bands from a set of frequency bands supported by the UE for data communication. As another example, the UE may support reception of legacy channels and signals via the main radio on one or more first frequency bands and reception of LP-WUS via the LP-WUR on one or more second frequency bands (e.g., where the one or more first frequency bands and the one or more second frequency bands may or may not include one or more common frequency bands) . For example, the UE may be configured to operate using a first frequency band or a first carrier for the LP-WUR and a second frequency band or a second carrier for the main radio. A frequency band refers to a range of frequencies within the electromagnetic spectrum, while a carrier is a single, specific frequency with certain frequency bandwidth within a frequency band used to transmit or receive signals.
[0030] As described herein, the UE may measure one or more signals using the LP-WUR for time and frequency tracking and radio resource management (RRM) measurement. However, RRM measurement information obtained via measurements performed using the LP-WUR may not reflect channel conditions for the main radio. For example, because the UE may be configured to operate the LP-WUR and the main radio using different frequency bands or carriers (e.g., the UE may be configured to operate the LP-WUR on a 700 megahertz (MHz) band and the main radio on a 3.5 gigahertz (GHz) band) , channel conditions for the main radio and the LP-WUR may vary due to frequency dependent channel effects. Additionally, because the UE may be configured to operate the LP-WUR and the main radio using different frequency bands or carriers, the UE may be configured to receive the LP-WUS with a first cell via the LP-WUR and perform data communication with a second cell via the main radio. In some examples, the first cell and the second cell may not be co-located (e.g., network nodes that are configured to support the first cell and the second cell may not be co-located) .
[0031] As a result, measurement information obtained via measurements performed using the LP-WUR may not reliably indicate channel conditions for the main radio. Therefore, if the UE uses the measurement information obtained via measurements performed using the LP-WUR for one or more RRM operations (such as serving cell and / or neighbor cell monitoring for the main radio) , then a performance of the one or more RRM operations may be degraded. For example, the UE may not accurately determine when a serving cell channel quality has degraded for the main radio or the UE is still within the coverage of the serving cell. This may result in the UE causing the main radio to wake up or be powered on after the UE has moved outside of a coverage area of the serving cell. This may increase latency associated with camping on a wireless communication network because the UE cannot rely on the serving cell to prepare and / or initiate a handover for the UE (e.g., because the UE may not have turned on the main radio until after the UE is outside of the coverage area of the serving cell) . Therefore, to reliably perform RRM measurements, the UE may use the main radio to perform measurements to obtain RRM measurement information. Without RRM measurement offloading from the main radio to the LP-WUR, power savings associated with the use of the LP-WUR may become marginal.
[0032] Various aspects relate generally to low-power wakeup signal monitoring. Some aspects more specifically relate to configurable conditions for main radio activation associated with LP-WUR-based RRM measurements. In some aspects, the configurable conditions may be applicable when a main radio and LP-WUR of a network entity are configured to operate using different frequency domain resources (e.g., different frequency bands and / or different carriers) . In some aspects, a first network entity (e.g., that has a processing system including a first radio and a second radio) may receive configuration information indicating one or more conditions associated with power state transitions for a first radio (e.g., for a main radio) . The first network entity may measure, using the second radio (e.g., an LP-WUR) while the first radio is configured to operate in a first power state (e.g., an off state or a sleep state) , one or more signals to obtain measurement information. The first network entity may perform an action to either transition the first radio from the first power state to a second power state or to cause the first radio to continue to operate in the first power state. The action may be based on whether the one or more conditions are satisfied. The one or more conditions may be satisfied based on the measurement information.
[0033] For example, the one or more conditions may include a threshold for a change in the measurement information obtained via the second radio. The measurement information may include a first value and a second value, and the one or more conditions may be satisfied based on a difference between the first value and the second value satisfying the threshold. If the one or more conditions are satisfied, then the action may include transitioning the first radio from the first power state to the second power state. If the one or more conditions are not satisfied, then the action may include continuing to operate the first radio in the first power state based on the one or more first conditions not being satisfied.
[0034] Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used to enable the first network entity to reliably use measurement information obtained via the second radio (e.g., an LP-WUR) for one or more RRM operations. This enables the network entity to conserve power by operating the first radio in the first power state (e.g., associated with a lower power consumption than the second power state) and using the second radio (e.g., the LP-WUR) to perform RRM measurements. By the network entity performing the action based on whether the one or more conditions are satisfied (e.g., to determine whether to transition the first radio from the first power state to the second power state) , the network entity may make improved power state transition determinations for the first radio based on the measurement information. For example, the one or more conditions being satisfied may be indicative of the network entity being mobile. Therefore, by the first network entity transitioning the first radio from the first power state to the second power state based on the one or more conditions being satisfied, the network entity may wake up the first radio before moving outside of a coverage area of a serving cell. This may enable the network entity to perform a cell reselection operation with the serving cell, reducing the latency associated with camping on a new cell.
[0035] 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 is not limited to any specific structure, function, example, aspect, or the like presented throughout this disclosure. This disclosure includes, for example, any aspect 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 includes 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. Any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.
[0036] Aspects and examples generally include a method, apparatus, network node, network entity, system, computer program product, non-transitory computer-readable medium, user equipment, base station, wireless communication device, and / or processing system as described or substantially described herein with reference to and as illustrated by the drawings and specification.
[0037] This disclosure may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. Characteristics of the example concepts disclosed herein, both their organization and method of operation, together with associated example advantages, are described in the following description and in connection with the accompanying figures. Each of the figures is provided for the purposes of illustration and description, and not as a definition of the limits of the claims. Each of the figures is provided for the purposes of illustration and description, and not as a definition of the limits of the claims.
[0038] While aspects are described in the present disclosure by illustration to some examples, those skilled in the art understand that such aspects may be implemented in many different arrangements and scenarios. Techniques described herein may be implemented using different platform types, devices, systems, shapes, sizes, and / or packaging arrangements. For example, some aspects may be implemented via integrated chip embodiments or other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, and / or artificial intelligence devices) . Aspects may be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components, and / or system-level components. Devices incorporating described example aspects and example features may include additional example components and example features for implementation and practice of claimed and described aspects. For example, transmission and reception of wireless signals may include one or more components for analog and digital purposes (e.g., hardware components including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders, and / or summers) . Aspects described herein may be practiced in a wide variety of devices, components, systems, distributed arrangements, and / or end-user devices of varying size, shape, and constitution.
[0039] As described above, wireless communication systems may be deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and / or other traffic. Some wireless communications systems may employ multiple-access radio access technologies (RATs) . The multiple-access RATs may be capable of supporting communication with multiple wireless communication devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and / or device transmit power, among other examples) . Examples of such multiple-access RATs 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, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0040] Multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable wireless communication devices to communicate on a local, municipal, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) . 5G NR may support enhanced mobile broadband (eMBB) access, Internet of Things (IoT) networks or reduced capability (RedCap) device deployments, ultra-reliable low-latency communication (URLLC) applications, and / or massive machine-type communication (mMTC) , among other examples.
[0041] To support these and other target verticals, a wireless communication system may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple-input multiple-output (MIMO) , beamforming, IoT device or RedCap device connectivity and management, industrial connectivity, licensed and unlicensed spectrum access, sidelink and other device-to-device direct communication (for example, cellular vehicle-to-everything (CV2X) communication) , frequency spectrum expansion, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, device aggregation, advanced duplex communication (for example, sub-band full-duplex (SBFD) ) , multiple-subscriber implementations, high-precision positioning, RF sensing, network energy savings (NES) , low-power signaling and radios, and / or artificial intelligence or machine learning (AI / ML) , among other examples.
[0042] The foregoing and other technological improvements may support use cases, such as wireless fronthauls, wireless midhauls, wireless backhauls, wireless data centers, extended reality (XR) and metaverse applications, meta services for supporting vehicle connectivity, holographic and mixed reality communication, autonomous and collaborative robots, vehicle platooning and cooperative maneuvering, sensing networks, gesture monitoring, human-brain interfacing, digital twin applications, asset management, and universal coverage applications using non-terrestrial and / or aerial platforms, among other examples.
[0043] As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases. The methods, operations, apparatuses, and techniques described herein may enable one or more of the foregoing technologies or new technologies and / or support one or more of the foregoing use cases or new use cases.
[0044] Fig. 1 is a diagram illustrating an example environment 100 in which apparatuses and / or methods described herein may be implemented, in accordance with the present disclosure. As shown in Fig. 1, the environment 100 may include a network entity 102, a network entity 104, and a network entity 106, that may communicate with one another via a network 108. The network entities 102, 104, and 106, may be dispersed throughout the network 108, and each network entity 102, 104, and 106 may be stationary and / or mobile. The network 108 may include wired communication connections, wireless communication connections, or a combination of wired and wireless communication connections.
[0045] The network 108 may include, for example, a cellular network (e.g., a Long-Term Evolution (LTE) network, a CDMA network, a 4G network, a 5G network, a 6G network, or another type of next generation network, and / or the like) , a public land mobile network (PLMN) , a local area network (LAN) , a wide area network (WAN) , a metropolitan area network (MAN) , a telephone network (e.g., the Public Switched Telephone Network (PSTN) ) , a private network, an ad hoc network, an intranet, the Internet, a fiber optic-based network, a cloud computing network, or the like, and / or a combination of these or other types of networks. The network 108 may include a wireless communication network 200, described in connection with Fig. 2.
[0046] As described herein, a network entity (which may alternatively be referred to as an entity, a node, a network node, or a wireless entity) may be, be similar to, include, or be included in (e.g., be a component of) a base station (e.g., any base station described herein, including a disaggregated base station) , a UE (e.g., any UE described herein) , a reduced capability (RedCap) device, an enhanced reduced capability (eRedCap) device, an ambient internet-of-things (IoT) device, an energy harvesting (EH) -capable device, a network controller, an apparatus, a device, a computing system, an integrated access and backhauling (IAB) node, a distributed unit (DU) , a central unit (CU) , a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU) ) , and / or another processing entity configured to perform any of the techniques described herein. For example, a network entity may be a UE. As another example, a network entity may be a base station. As used herein, “network entity” may refer to an entity that is configured to operate in a network, such as the network 108. For example, a “network entity” is not limited to an entity that is currently located in and / or currently operating in the network. Rather, a network entity may be any entity that is capable of communicating and / or operating in the network. A network entity may include a network node 210 or a UE 220, described in more detail in connection with Fig. 2.
[0047] The adjectives “first, ” “second, ” “third, ” and so on are used for contextual distinction between two or more of the modified noun in connection with a discussion and are not meant to be absolute modifiers that apply only to a certain respective entity throughout the entire document. For example, a network entity may be referred to as a “first network entity” in connection with one discussion and may be referred to as a “second network entity” in connection with another discussion, or vice versa. As an example, a first network entity may be configured to communicate with a second network entity or a third network entity. In one aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third network entity may be a UE. In another aspect of this example, the first network entity may be a UE, the second network entity may be a base station, and the third network entity may be a base station. In yet other aspects of this example, the first, second, and third network entities may be different relative to these examples.
[0048] Similarly, reference to a UE, base station, apparatus, device, computing system, or the like may include disclosure of the UE, base station, apparatus, device, computing system, or the like being a network entity. For example, disclosure that a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity. Consistent with this disclosure, once a specific example is broadened in accordance with this disclosure (e.g., a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity) , the broader example of the narrower example may be interpreted in the reverse, but in a broad open-ended way. In the example above where a UE is configured to receive information from a base station also discloses that a first network entity is configured to receive information from a second network entity, “first network entity” may refer to a first UE, a first base station, a first apparatus, a first device, a first computing system, a first set of one or more one or more components, a first processing entity, or the like configured to receive the information; and “second network entity” may refer to a second UE, a second base station, a second apparatus, a second device, a second computing system, a second set of one or more components, a second processing entity, or the like.
[0049] As described herein, communication of information (e.g., any information, signal, or the like) may be described in various aspects using different terminology. Disclosure of one communication term includes disclosure of other communication terms. For example, a first network entity may be described as being configured to transmit information to a second network entity. In this example and consistent with this disclosure, disclosure that the first network entity is configured to transmit information to the second network entity includes disclosure that the first network entity is configured to provide, send, output, communicate, or transmit information to the second network entity. Similarly, in this example and consistent with this disclosure, disclosure that the first network entity is configured to transmit information to the second network entity includes disclosure that the second network entity is configured to receive, obtain, or decode the information that is provided, sent, output, communicated, or transmitted by the first network entity.
[0050] As shown, the network entity 102 may include a processing system 110. Similarly, the network entity 106 may include a processing system 112. A processing system may include one or more components (or subcomponents) , such as one or more components described herein. For example, a respective component of the one or more components may be, be similar to, include, or be included in at least one memory, at least one communication interface, or at least one processor. For example, a processing system may include one or more components. In such an example, the one or more components may include a first component, a second component, and a third component. In this example, the first component may be coupled to a second component and a third component. In this example, the first component may be at least one processor, the second component may be a communication interface, and the third component may be at least one memory. A processing system may generally be a system including one or more components that may perform one or more functions, such as any function or combination of functions described herein. For example, one or more components may receive input information (e.g., any information that is an input, such as a signal, any digital information, or any other information) , one or more components may process the input information to generate output information (e.g., any information that is an output, such as a signal or any other information) , one or more components may perform any function as described herein, or any combination thereof. A processing system (which may include the processing system 110 and the processing system 112) is described in more detail in connection with Fig. 2, such as in connection with processing system 240 and processing system 245.
[0051] As described herein, an “input” and “input information” may be used interchangeably. Similarly, as described herein, an “output” and “output information” may be used interchangeably. Any information generated by any component may be provided to one or more other systems or components of, for example, a network entity described herein. For example, a processing system may include a first component configured to receive or obtain information, a second component configured to process the information to generate output information, and / or a third component configured to provide the output information to other systems or components. In this example, the first component may be a communication interface (e.g., a first communication interface) , the second component may be at least one processor (e.g., that is coupled to the communication interface and / or at least one memory) , and the third component may be a communication interface (e.g., the first communication interface or a second communication interface) . For example, a processing system may include at least one memory, at least one communication interface, and / or at least one processor, where the at least one processor may, for example, be coupled to the at least one memory and the at least one communication interface.
[0052] A processing system of a network entity described herein may interface with one or more other components of the network entity, may process information received from one or more other components (such as input information) , or may output information to one or more other components.

In some examples, the first communication interface may be an interface configured to receive input information, and the information may be provided to the processing system. In some examples, the second system interface may be configured to transmit information output from the chip or modem. The second communication interface may also obtain or receive input information, and the first communication interface may also output, transmit, or provide information.
[0053] For example, as shown in Fig. 1, the processing system 110 may include a (e.g., one or more) communication manager 114 and one or more communication interfaces 116. The communication manager 114 may be configured to perform one or more communication tasks as described herein. In some aspects, the communication manager 114 may direct the communication interface 120 and / or the processing system 110 to perform one or more communication tasks as described herein. Similarly, the processing system 112 may include a (e.g., one or more) communication manager 118 and one or more communication interfaces 120. The communication manager 118 may be configured to perform one or more communication tasks as described herein. In some aspects, the processing system 112 and / or the communication manager 118 may direct the communication interface 120 to perform one or more communication tasks as described herein. Although depicted, for clarity of description, with reference only to the network entities 102 and 104, any one or more of the network entities 102, 104, and 106 also may include a communication manager and a communication interface.
[0054] As used herein, “communication interface” refers to an interface that enables communication (e.g., wireless communication, wired communication, or a combination thereof) between a first network entity and a second network entity. A communication interface may include electronic circuitry that enables a network entity to transmit, receive, or otherwise perform the communication. A communication interface may be, be similar to, include, or be included in one or more components that are configured to enable communication between the first network entity and the second network entity. For example, a communication interface may include a transmission component, a reception component, and / or a transceiver, among other examples. For example, a communication interface may include one or more transceivers, one or more receivers, and / or one or more transmitters configured to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. In some examples, a communication interface may include one or more RF components, an RF front end, one or more antennas, one or more transmit or receive processors, a demodulation component, and / or a modulation component, among other examples.
[0055] A communication interface may include a transmission component and / or a reception component. For example, a communication interface may include a transceiver and / or one or more separate receivers and / or transmitters that enable a network entity to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. In some examples, a communication interface may include one or more radio frequency reflective elements and / or one or more radio frequency refractive elements.

[0056] As described herein, a network entity (e.g., the network entity 102 and / or the network entity 106) may be configured to perform one or more operations. Reference to a network entity being configured to perform one or more operations may refer to a processing system of the network entity being configured to perform the one or more operations and / or the processing system being configured to cause one or more components of the network entity to perform the one or more operations. For example, reference to the processing system being configured to perform one or more operations may refer to one or more components (or subcomponents) of the processing system performing the one or more operations. For example, the one or more components of the processing system may include at least one memory, at least one processor, and / or at least one communication interface, among other examples, that are configured to perform one or more (or all) of the one or more operations, and / or any combination thereof. Where reference is made to the network entity and / or the processing system being configured to perform operations, the network entity and / or the processing system may be configured to cause one component to perform all operations, or to cause more than one component to collectively perform the operations. When the network entity and / or the processing system is configured to cause more than one component to collectively perform the operations, each operation need not be performed by each of those components (e.g., different operations may be performed by different components) and / or each operation need not be performed in whole by only one component (e.g., different components may perform different sub-functions of an operation) .
[0057] As described in more detail elsewhere herein, the network entity 102 may (e.g., the processing system 110 may, or the processing system 110 may cause the communication manager 114 and / or the communication interface 116 to) receive first configuration information indicating one or more first conditions associated with power state transitions for a first radio of the processing system 110; measure, using a second radio of the processing system 110 while the first radio is configured to operate in a first power state, one or more first signals to obtain first measurement information, wherein the first radio is configured to operate using first frequency resources and the second radio is configured to operate using second frequency resources; and / or perform a first action to either transition the first radio from the first power state to a second power state or to cause the first radio to continue to operate in the first power state, wherein the first action is based on whether the one or more first conditions are satisfied, and wherein the one or more first conditions are satisfied based on the first measurement information. Additionally, or alternatively, the network entity 102 and / or the communication manager 114 may perform one or more other operations described herein.
[0058] As described in more detail elsewhere herein, the network entity 106 may (e.g., the processing system 112 may, or the processing system 112 may cause the communication manager 114 and / or the communication interface 116 to) transmit first configuration information indicating one or more first conditions associated with power state transitions for a first radio of a second network entity (e.g., the network entity 102) , wherein the one or more first conditions being met is based on first measurement information that is configured to be obtained via a second radio of the second network entity; receive the first measurement information; and / or transmit second configuration information indicating one or more second conditions associated with the power state transitions for the first radio of the second network entity, wherein the one or more second conditions are based on the first measurement information. Additionally, or alternatively, the network entity 106 and / or the communication manager 118 may perform one or more other operations described herein.
[0059] The number and arrangement of entities shown in Fig. 1 are provided as one or more examples. In practice, there may be additional network entities and / or networks, fewer network entities and / or networks, different network entities and / or networks, or differently arranged network entities and / or networks than those shown in Fig. 1. Furthermore, the network entity 102, 104, and 106 may be implemented using a single apparatus or multiple apparatuses.
[0060] Fig. 2 is a diagram illustrating an example of a wireless communication network 200, in accordance with the present disclosure. The wireless communication network 200 may be or may include elements of a 5G (or NR) network or a 6G network, among other examples. The wireless communication network 200 may include multiple network nodes 210. For example, in Fig. 2, the wireless communication network 200 includes a network node (NN) 210a and a network node 210b. The network nodes 210 may support communications with multiple UEs 220. For example, in Fig. 2, the network nodes 210 support communication with a UE 220a, a UE 220b, and a UE 220c. In some examples, a UE 220 may also communicate with other UEs 220 and a network node 210 may communicate with a core network and with other network nodes 210.
[0061] The network nodes 210 and the UEs 220 of the wireless communication network 200 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, carriers, and / or channels. For example, devices of the wireless communication network 200 may communicate using one or more operating bands. In some aspects, multiple wireless communication networks 200 may be deployed in a given geographic area. Each wireless communication network 200 may support a particular RAT (which may also be referred to as an air interface) and may operate on one or more carrier frequencies in one or more frequency bands or ranges. In some examples, when multiple RATs are deployed in a given geographic area, each RAT in the geographic area may operate on different frequencies to avoid interference with other RATs. Additionally or alternatively, in some examples, the wireless communication network 200 may implement dynamic spectrum sharing (DSS) , in which multiple RATs are implemented with dynamic bandwidth allocation (for example, based on user demand) in a single frequency band. In some examples, the wireless communication network 200 may support communication over unlicensed spectrum, where access to an unlicensed channel is subject to a channel access mechanism. For example, in a shared or unlicensed frequency band, a transmitting device may perform a channel access procedure, such as a listen-before-talk (LBT) procedure, to contend against other devices for channel access before transmitting on a shared or unlicensed channel.
[0062] Various operating bands have been defined as frequency range designations FR1 (410 MHz through 7.125 GHz) , FR2 (24.25 GHz through 52.6 GHz) , FR3 (7.125 GHz through 24.25 GHz) , FR4a or FR4-1 (52.6 GHz through 71 GHz) , FR4 (52.6 GHz through 114.25 GHz) , and FR5 (114.25 GHz through 300 GHz) . Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in some documents and articles. Similarly, FR2 is often referred to (interchangeably) as a “millimeter wave” band in some documents and articles, despite being different than the extremely high frequency (EHF) band (30 GHz through 300 GHz) , which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. The frequencies between FR1 and FR2 are often referred to as mid-band frequencies, which include FR3. Frequency bands falling within FR3 may inherit FR1 characteristics or FR2 characteristics, and thus may effectively extend features of FR1 or FR2 into the mid-band frequencies. Thus, “sub-6 GHz, ” if used herein, may broadly refer to frequencies that are less than 6 GHz, that are within FR1, and / or that are included in mid-band frequencies. Similarly, the term “millimeter wave, ” if used herein, may broadly refer to mid-band frequencies or to frequencies that are within FR2, FR4, FR4-aor FR4-1, FR5, and / or the EHF band. Higher frequency bands may extend 5G NR operation, 6G operation, and / or other RATs beyond 52.6 GHz.
[0063] A network node 210 and / or a UE 220 may include one or more devices, components, or systems that enable communication with other devices, components, or systems of the wireless communication network 200. For example, a UE 220 and a network node 210 may each include one or more chips, system-on-chips (SoCs) , chipsets, packages, or devices that individually or collectively constitute or comprise a processing system, such as a processing system 240 of the UE 220 or a processing system 245 of the network node 210. The processing system 240 and the processing system 245 may be similar to other processing systems described herein, such as the processing system 110 and the processing system 112. A processing system (for example, the processing system 240 and / or the processing system 245) includes processor (or “processing” ) circuitry in the form of one or multiple processors, microprocessors, processing units (such as central processing units (CPUs) , graphics processing units (GPUs) , neural processing units (NPUs) (also referred to as neural network processors or deep learning processors (DLPs) ) , and / or digital signal processors (DSPs) ) , processing blocks, application-specific integrated circuits (ASICs) , programmable logic devices (PLDs) , or other discrete gate or transistor logic or circuitry (any one or more of which may be generally referred to herein individually as a “processor” or collectively as “the processor” or “the processor circuitry” ) . Such processors may be individually or collectively configurable or configured to perform various functions or operations described herein. A group of processors collectively configurable or configured to perform a set of functions may include a first processor configurable or configured to perform a first function of the set and a second processor configurable or configured to perform a second function of the set. In some other examples, each of a group of processors may be configurable or configured to perform a same set of functions.
[0064] The processing system 240 and the processing system 245 may each include memory circuitry in the form of one or multiple memory devices, memory blocks, memory elements, or other discrete gate or transistor logic or circuitry, each of which may include or implement tangible storage media such as random-access memory (RAM) or read-only memory (ROM) , or combinations thereof (any one or more of which may be generally referred to herein individually as a “memory” or collectively as “the memory” or “the memory circuitry” ) . One or more of the memories may be coupled (for example, operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) with one or more of the processors and may individually or collectively store processor-executable code or instructions (such as software) that, when executed by one or more of the processors, may configure one or more of the processors to perform various functions or operations described herein. Additionally or alternatively, in some examples, one or more of the processors may be configured to perform various functions or operations described herein without requiring configuration by software. “Software” shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, or functions, among other examples, whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
[0065] The processing system 240 and the processing system 245 may each include or be coupled with one or more modems (such as a cellular (for example, a 5G or 6G compliant) modem) . In some examples, one or more processors of the processing system 240 and / or the processing system 245 include or implement one or more of the modems. The processing system 240 and the processing system 245 may also include or be coupled with multiple radios (collectively “the radio” ) , multiple RF chains, or multiple transceivers, each of which may in turn be coupled with one or more of multiple antennas. In some examples, one or more processors of the processing system 240 and / or the processing system 245 include or implement one or more of the radios, RF chains, or transceivers. An RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs) , and / or other devices that convert between an analog signal (such as for transmission or reception via an air interface) and a digital signal (such as for processing by the processing system 240 of the UE 220 or by the processing system 245 of the network node 210) .
[0066] A network node 210 and a UE 220 may each include one or multiple antennas or antenna arrays. Typical network nodes 210 and UEs 220 may include multiple antennas, which may be organized or structured into one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. As used herein, the term “antenna” can refer to one or more antennas, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays. The term “antenna panel” can refer to a group of antennas (such as antenna elements) arranged in an array or panel, which may facilitate beamforming by manipulating parameters associated with the group of antennas. The term “antenna module” may refer to circuitry including one or more antennas as well as one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device such as the network node 210 and the UE 220.
[0067] A network node 210 may be, may include, or may also be referred to as an NR network node, a 5G network node, a 6G network node, a Node B, a gNB, an access point (AP) , a transmission reception point (TRP) , a network entity, a network element, a network equipment, and / or another type of device, component, or system included in a radio access network (RAN) . In various deployments, a network node 210 may be implemented as a single physical node (for example, a single physical structure) or may be implemented as two or more physical nodes (for example, two or more distinct physical structures) . For example, a network node 210 may be a device or system that implements a part of a radio protocol stack, a device or system that implements a full radio protocol stack (such as a full gNB protocol stack) , or a collection of devices or systems that collectively implement the full radio protocol stack. For example, and as shown, a network node 210 may be an aggregated network node having an aggregated architecture, meaning that the network node 210 may implement a full radio protocol stack that is physically and logically integrated within a single physical structure in the wireless communication network 200. For example, an aggregated network node 210 may consist of a single standalone base station or a single TRP that operates with a full radio protocol stack to enable or facilitate communication between a UE 220 and a core network of the wireless communication network 200.
[0068] Alternatively, and as also shown, a network node 210 may be a disaggregated network node (sometimes referred to as a disaggregated base station) , having a disaggregated architecture, meaning that the network node 210 may operate with a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same geographic location or in different geographic locations. An example disaggregated network node architecture is described in more detail below with reference to Fig. 2. In some deployments, disaggregated network nodes 210 may be used in an IAB network, in an open radio access network (O-RAN) (such as a network configuration in compliance with the O-RAN Alliance) , or in a virtualized radio access network (vRAN) , also known as a cloud radio access network (C-RAN) , to facilitate scaling by separating network functionality into multiple units or modules that can be individually deployed.
[0069] The network nodes 210 of the wireless communication network 200 may include one or more CUs, one or more DUs, and one or more RUs. A CU may host one or more higher layers, such as a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, and a service data adaptation protocol (SDAP) layer, among other examples. A DU may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and / or one or more higher physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some examples, a DU also may host a lower PHY layer that is configured to perform functions, such as a fast Fourier transform (FFT) , an inverse FFT (IFFT) , beamforming, and / or physical random access channel (PRACH) extraction and filtering, among other examples. An RU may perform RF processing functions or lower PHY layer functions, such as an FFT, an IFFT, beamforming, or PRACH extraction and filtering, among other examples, according to a functional split, such as a lower layer split (LLS) . In such an architecture, each RU can be operated to handle over the air (OTA) communication with one or more UEs 220. In some examples, a single network node 210 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. In some examples, a CU, a DU, and / or an RU may be implemented as a virtual unit, such as a virtual central unit (VCU) , a virtual distributed unit (VDU) , or a virtual radio unit (VRU) , among other examples, which may be implemented as a virtual network function, such as in a cloud deployment.
[0070] Some network nodes 210 (for example, a base station, an RU, or a TRP) may provide communication coverage for a particular geographic area. The term “cell” can refer to a coverage area of a network node 210 or to a network node 210 itself, depending on the context in which the term is used. A network node 210 may support one or more cells (for example, each cell may support communication within an angular (for example, 60 degree) range around the network node) . In some examples, a network node 210 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs 220 with associated service subscriptions. A pico cell may cover a relatively small geographic area and may also allow unrestricted access by UEs 220 with associated service subscriptions. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs 220 having association with the femto cell (for example, UEs 220 in a closed subscriber group (CSG) ) . In some examples, a cell may not necessarily be stationary. For example, the geographic area of the cell may move according to the location of an associated mobile network node 210 (for example, a train, a satellite, an unmanned aerial vehicle, or an NTN network node) .
[0071] The wireless communication network 200 may be a heterogeneous network that includes network nodes 210 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, aggregated network nodes, and / or disaggregated network nodes, among other examples. Various different types of network nodes 210 may generally transmit at different power levels, serve different coverage areas (for example, a cell 230a and a cell 230b) , and / or have different impacts on interference in the wireless communication network 200 than other types of network nodes 210.
[0072] The UEs 220 may be physically dispersed throughout the coverage area of the wireless communication network 200, and each UE 220 may be stationary or mobile. A UE 220 may be, may include, or may also be referred to as an access terminal, a mobile station, or a subscriber unit. A UE 220 may be, include, or be coupled with a cellular phone (for example, 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 netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry) , a gaming device, an entertainment device (for example, a music device, a video device, or a satellite radio) , an XR device, a vehicular component or sensor, a smart meter or sensor, industrial manufacturing equipment, a global navigation satellite system (GNSS) device (such as a global positioning system (GPS) device or another type of positioning device) , a UE function of a network node, and / or any other suitable device or function that may communicate via a wireless medium.
[0073] Some UEs 220 may be classified according to different categories in association with different complexities and / or different capabilities. UEs 220 in a first category may facilitate massive IoT in the wireless communication network 200, and may offer low complexity and / or cost relative to UEs 220 in a second category. UEs 220 in a second category may include mission-critical IoT devices, legacy UEs, baseline UEs, high-tier UEs, advanced UEs, full-capability UEs, and / or premium UEs that are capable of URLLC, eMBB, and / or precise positioning in the wireless communication network 200, among other examples. A third category of UEs 220 may have mid-tier complexity and / or capability (for example, a capability between that of the UEs 220 of the first category and that of the UEs 220 of the second capability) . A UE 220 of the third category may be referred to as a reduced capability UE (“RedCap UE” ) , a mid-tier UE, an NR-Light UE, and / or an NR-Lite UE, among other examples. RedCap UEs may bridge a gap between the capability and complexity of NB-IoT devices and / or eMTC UEs, and mission-critical IoT devices and / or premium UEs. RedCap UEs may include, for example, wearable devices, IoT devices, industrial sensors, or cameras that are associated with a limited bandwidth, power capacity, and / or transmission range, among other examples. RedCap UEs may support healthcare environments, building automation, electrical distribution, process automation, transport and logistics, or smart city deployments, among other examples.
[0074] In some examples, a network node 210 may be, may include, or may operate as an RU, a TRP, or a base station that communicates with one or more UEs 220 via a radio access link (which may be referred to as a “Uu” link) . The radio access link may include a downlink and an uplink. “Downlink” (or “DL” ) refers to a communication direction from a network node 210 to a UE 220, and “uplink” (or “UL” ) refers to a communication direction from a UE 220 to a network node 210. Downlink and uplink resources may include time domain resources (for example, frames, subframes, slots, and symbols) , frequency domain resources (for example, frequency bands, component carriers (CCs) , subcarriers, resource blocks, and resource elements) , and spatial domain resources (for example, particular transmit directions or beams) .
[0075] Frequency domain resources may be subdivided into bandwidth parts (BWPs) . A BWP may be a block of frequency domain resources (for example, a continuous set of resource blocks (RBs) within a full component carrier bandwidth) that may be configured at a UE-specific level. A UE 220 may be configured with both an uplink BWP and a downlink BWP (which may be the same or different) . Each BWP may be associated with its own numerology (indicating a sub-carrier spacing (SCS) and cyclic prefix (CP) ) . A BWP may be dynamically configured or activated (for example, by a network node 210 transmitting a downlink control information (DCI) configuration to the one or more UEs 220) and / or reconfigured (for example, in real-time or near-real-time) according to changing network conditions in the wireless communication network 200 and / or specific requirements of one or more UEs 220. An active BWP defines the operating bandwidth of the UE 220 within the operating bandwidth of the serving cell. The use of BWPs enables more efficient use of the available frequency domain resources in the wireless communication network 200 because fewer frequency domain resources may be allocated to a BWP for a UE 220 (which may reduce the quantity of frequency domain resources that a UE 220 is required to monitor and reduce UE power consumption by enabling the UE to monitor fewer frequency domain resources) , leaving more frequency domain resources to be spread across multiple UEs 220. Thus, BWPs may also assist in the implementation of lower-capability (for example, RedCap) UEs 220 by facilitating the configuration of smaller bandwidths for communication by such UEs 220 and / or by facilitating reduced UE power consumption.
[0076] As used herein, a downlink signal may be or include a reference signal, control information, or data. For example, downlink reference signals include a primary synchronization signal (PSS) , a secondary SS (SSS) , an SS block (SSB) (for example, that includes a PSS, an SSS, and a physical broadcast channel (PBCH) ) , a demodulation reference signal (DMRS) , a phase tracking reference signal (PTRS) , a tracking reference signal (TRS) , and a channel state information (CSI) reference signal (CSI-RS) , among other examples. A downlink signal carrying control information or data may be transmitted via a downlink channel. Downlink channels may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Downlink reference signals may be transmitted in addition to, or multiplexed with, downlink control channel communications and / or downlink data channel communications. A downlink control channel may be specifically used to transmit DCI from a network node 210 to a UE 220. DCI generally contains the information the UE 220 needs to identify RBs in a subsequent subframe and how to decode them, including a modulation and coding scheme (MCS) or redundancy version parameters. Different DCI formats carry different information, such as scheduling information in the form of downlink or uplink grants, slot formal indicators (SFIs) , preemption indicators (PIs) , transmit power control (TPC) commands, hybrid automatic repeat request (HARQ) information, new data indicators (NDIs) , among other examples. A downlink data channel may be used to transmit downlink data (for example, user data associated with a UE 220) from a network node 210 to a UE 220. Downlink control channels may include PDCCHs, and downlink data channels may include physical downlink shared channels (PDSCHs) . Control information or data communications may be transmitted on a PDCCH and PDSCH, respectively. For example, a PDCCH can carry DCI, while a PDSCH can carry a MAC control element (MAC-CE) , an RRC message, or user data, among other examples. Each PDSCH may carry one or more transport blocks (TBs) of data.
[0077] As used herein, an uplink signal may include a reference signal, control information, or data. For example, uplink reference signals include a sounding reference signal (SRS) , a PTRS, and a DMRS, among other examples. An uplink signal carrying control information or data may be transmitted via an uplink channel. An uplink channel may include one or more control channels for transmitting control information and one or more data channels for transmitting data. Uplink reference signals may be transmitted in addition to, or multiplexed with, uplink control channel communications and / or uplink data channel communications. An uplink control channel may be specifically used to transmit uplink control information (UCI) from a UE 220 to a network node 210. An uplink data channel may be used to transmit uplink data (for example, user data associated with a UE 220) from a UE 220 to a network node 210. Uplink control channels may include physical uplink control channels (PUCCHs) , and uplink data channels may include physical uplink shared channels (PUSCHs) . Control information or data communications may be transmitted on a PUCCH and PUSCH, respectively. For example, a PUCCH can carry UCI, while a PUSCH can carry a MAC-CE, an RRC message, or user data, among other examples. UCI can include a scheduling request (SR) , HARQ feedback information (for example, a HARQ acknowledgement (ACK) indication or a HARQ negative acknowledgement (NACK) indication) , uplink power control information (for example, an uplink TPC parameter) , and / or CSI, among other examples. CSI can include a channel quality indicator (CQI) (indicative of downlink channel conditions to facilitate selection of transmission parameters, such as an MCS, by a network node 210) , a precoding matrix indicator (PMI) , a CSI-RS resource indicator (CRI) (for example, indicative of a beam used to transmit a CSI-RS) , an SS / PBCH resource block indicator (SSBRI) (for example, indicative of a beam used to transmit an SSB) , a layer indicator (LI) , a rank indicator (RI) , and / or measurement information (for example, a layer 1 (L1) -reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, among other examples) which can be used for beam management, among other examples. Each PUSCH may carry one or more TBs of data.
[0078] The information (for example, data, control information, or reference signal information) transmitted by a network node 210 to a UE 220, or vice versa, may be represented as a sequence of binary bits that are mapped (for example, modulated) to an analog signal waveform (for example, a discrete Fourier transform (DFT) -spread-orthogonal frequency division multiplexing (OFDM) (DFT-s-OFDM) waveform or a CP-OFDM waveform) that is transmitted by the network node 210 or UE 220 over a wireless communication channel. In some examples, the network node 210 or the UE 220 (for example, using the processing system 245 or the processing system 240, respectively) may select an MCS (for example, an order of quadrature amplitude modulation (QAM) , such as 64-QAM, 128-QAM, or 256-QAM, among other examples) for a downlink signal or an uplink signal. For example, the network node 210 may select an MCS for a downlink signal in accordance with UCI received from the UE 220. The network node 210 may transmit, to the UE 220, an indication of the selected MCS for the downlink signal, such as via DCI that schedules the downlink signal. As another example, the network node 210 may transmit, and the UE 220 may receive, an indication of an MCS to be applied for the one or more uplink signals, such as via DCI scheduling transmission of the one or more uplink signals.
[0079] The network node 210 or the UE 220 (such as by using the processing system 245 or the processing system 240, respectively, and / or one or more coupled modems) may perform signal processing on the information (such as filtering, amplification, modulation, digital-to-analog conversion, an IFFT operation, multiplexing, interleaving, mapping, and / or encoding, among other examples) to generate a processed signal in accordance with the selected MCS. In some examples, the network node 210 or the UE 220 (for example, using the processing system 245 or the processing system 240, respectively, and / or one or more coupled encoders or modems) may perform a channel coding operation or a forward error correction (FEC) operation to control errors in transmitted information. For example, the network node 210 or the UE 220 may perform an encoding operation to generate encoded information (such as by selectively introducing redundancy into the information, typically using an error correction code (ECC) , such as a polar code or a low-density parity-check (LDPC) code) . The network node 210 or the UE 220 (for example, using the processing system 245 and / or one or more modems) may further perform spatial processing (for example, precoding) on the encoded information to generate one or more processed or precoded signals for downlink or uplink transmission, respectively. In some examples, the network node 210 or the UE 220 may perform codebook-based precoding or non-codebook-based precoding. Codebook-based precoding may involve selecting a precoder (for example, a precoding matrix) using a codebook. For example, the network node 210 may provide precoding information indicating which precoder, defined by the codebook, is to be used by the UE 220. Non-codebook-based precoding may involve selecting or deriving a precoder based on, or otherwise associated with, one or more downlink or uplink signal measurements. The network node 210 or the UE 220 may transmit the processed downlink or uplink signals, respectively, via one or more antennas.
[0080] The network node 210 or the UE 220 may receive uplink signals or downlink signals, respectively, via one or more antennas. The network node 210 or the UE 220 (for example, using the processing system 245 or the processing system 240, respectively, and / or one or more coupled modems) may perform signal processing (for example, in accordance with the MCS) on the received uplink or downlink signals, respectively (such as filtering, amplification, demodulation, analog-to-digital conversion, an FFT operation, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, and / or decoding, among other examples) , to map the received signal (s) to a sequence of binary bits (for example, received information) that estimates the information transmitted by the network node 210 or the UE 220 via the downlink or uplink signals. The network node 210 or the UE 220 (for example, using the processing system 245 or the processing system 240, respectively, and / or a coupled decoder or one or more modems) may decode the received information (such as by using an ECC, a decoding operation, and / or an FEC operation) to detect errors and / or correct bit errors in the received information to generate decoded information. The decoded information may estimate the information transmitted via the downlink or uplink signals.
[0081] Communications (e.g., transmission and / or reception of signals) between entities (e.g., between a UE 220 and a network node 210) may consume some amount of power. For example, a UE 220 may consume a lower amount of power while in a low power state (such as while not connected to a network or while waiting for paging from the network) , and may consume a higher amount of power while in a full power state (such as while actively communicating with a network node or while monitoring for control information from the network) . Certain components of the UE 220 may consume a significant amount of power. For example, a radio of the UE 220, which may support bidirectional communication (such as both transmission and reception) , multi-layer communication, or larger bandwidths (such as a communication bandwidth of the UE 220) , may consume power while active, such as in the course of communicating or monitoring for control information.
[0082] Some techniques provide power savings at the UE 220 by limiting the amount or ratio of time in which a radio is active, relative to the amount of time in which the radio is inactive or powered down. For example, a connected-mode discontinuous reception (C-DRX) cycle may provide off durations (sometimes referred to as inactive times or sleep durations) in which the radio is inactive, and on durations (sometimes referred to as active times or wake durations) in which the radio is active. The UE 220 may monitor for a PDCCH during an on duration, and may extend the on duration if a PDCCH is received, which facilitates further communication in accordance with the PDCCH. Thus, power consumption of the main radio may be reduced by reducing the amount of time in which the main radio is active and / or monitoring for a PDCCH.
[0083] While the C-DRX cycle reduces power consumption at the UE 220 and the network, further power savings may be desirable, particularly in 5G, 6G, and similar RATs where beamforming and high-frequency communication cause increased power consumption relative to other RATs. To achieve further power savings, a UE 220 (such as the UE 220a as shown in Fig. 2) may include or be associated with a second LP-WUR 270. Relative to a non-LP-WUR (e.g., a main radio (MR) 275 of the UE 220) , the LP-WUR 270 may have reduced power consumption. For example, the LP-WUR 270 may be configured with a reduced bandwidth, reduced processing capabilities, or other reduced capabilities, relative to a main radio, which facilitate operation with reduced power consumption. In one particular example, the LP-WUR 270 may be configured to use an envelope detector type of receiver architecture, with on-off keying (OOK) modulation, to enable the UE 220a to perform signaling monitoring with low power consumption. As shown in Fig. 2, the main radio 275 and the LP-WUR 270 may be associated with, may be included in, and / or may be components of the processing system 240 of the UE 220a. In other examples, the main radio 275 and / or the LP-WUR 270 may be separate from the processing system 240.
[0084] The LP-WUR 270 may facilitate indication, from the network, for the UE 220a to exit a low power state, such as by waking up the main radio 275. For example, while the main radio 275 is in a low power state, the LP-WUR 270 may receive a signal referred to as an LP-WUS, and may trigger the main radio to exit the low power state and may trigger a UE 220a to transfer from an idle mode to an active mode to receive PDCCH paging. In another example, when a UE 220a is operating in a connected mode, the LP-WUS may trigger UE PDCCH monitoring. In some configurations, the LP-WUS and / or LP-WUR 270 can be implemented in conjunction with a C-DRX cycle, such that the UE 220a may keep the main radio 275 in an inactive state or off state during an on duration of the C-DRX cycle if the LP-WUR 270 has not received or detected an LP-WUS in association with (e.g., before) the on duration, thereby further reducing power consumption relative to the UE 220a waking up (e.g., powering on the main radio 275) during an on duration in which the UE 220a will not receive a PDCCH.
[0085] In some examples, a UE 220 and a network node 210 may perform MIMO communication. “MIMO” generally refers to transmitting or receiving multiple signals (such as multiple layers or multiple data streams) simultaneously over the same time and frequency resources. MIMO techniques generally exploit multipath propagation. A network node 210 and / or UE 220 may communicate using massive MIMO, multi-user MIMO, or single-user MIMO, which may involve rapid switching between beams or cells. For example, the amplitudes and / or phases of signals transmitted via antenna elements and / or sub-elements may be modulated and shifted relative to each other (such as by manipulating a phase shift, a phase offset, and / or an amplitude) to generate one or more beams, which is referred to as beamforming. For example, the network node 210b may generate one or more beams 260a, and the UE 220b may generate one or more beams 260b. The term “beam” may refer to a directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction, a directional reception of a wireless signal from a transmitting device or otherwise in a desired direction, a direction associated with a directional transmission or directional reception, a set of directional resources associated with a signal transmission or signal reception (for example, an angle of arrival, a horizontal direction, and / or a vertical direction) , a set of parameters that indicate one or more aspects of a directional signal, a direction associated with the signal, and / or a set of directional resources associated with the signal, among other examples.
[0086] MIMO may be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO may include a massive MIMO technique which may be associated with an increased (for example, “massive” ) quantity of antennas at the network node 210 and / or at the UE 220, such as in a network implementing mmWave technology. Massive MIMO may improve communication reliability by enabling a network node 210 and / or a UE 220 to communicate the same data across different propagation (or spatial) paths. In some examples, MIMO may support simultaneous transmission to multiple receivers, referred to as multi-user MIMO (MU-MIMO) . Some RATs may employ MIMO techniques, such as multi-TRP (mTRP) operation (including redundant transmission or reception on multiple TRPs) , reciprocity in the time domain or the frequency domain, single-frequency-network (SFN) transmission, or non-coherent joint transmission (NC-JT) .
[0087] To support MIMO techniques, the network node 210 and the UE 220 may perform one or more beam management operations, such as an initial beam acquisition operation, one or more beam refinement operations, and / or a beam recovery operation. For example, an initial beam acquisition operation may involve the network node 210 transmitting signals (for example, SSBs, CSI-RSs, or other signals) via respective beams (for example, of the beams 260a of the network node 210) and the UE 220 receiving and measuring the signal (s) via respective beams of multiple beams (for example, from the beams 260b of the UE 220) to identify a best beam (or beam pair) for communication between the UE 220 and the network node 210. For example, the UE 220 may transmit an indication (for example, in a message associated with a random access channel (RACH) operation) of a (best) identified beam of the network node 210 (for example, by indicating an SSBRI or other identifier associated with the beam) . A beam refinement operation may involve a first device (for example, the UE 220 or the network node 210) transmitting signal (s) via a subset of beams (for example, identified based on, or otherwise associated with, measurements reported as part of one or more other beam management operations) . A second device (for example, the network node 210 or the UE 220) may receive the signal (s) via a single beam (for example, to identify the best beam for communication from the subset of beams) . The beam (s) may be identified via one or more spatial parameters, such as a transmission configuration indicator (TCI) state and / or a quasi co-location (QCL) parameter, among other examples. The network node 210 and the UE 220 may increase reliability and / or achieve efficiencies in throughput, signal strength, and / or other signal properties for massive MIMO operations by performing the beam management operations.
[0088] Some aspects and techniques as described herein may be implemented, at least in part, using an artificial intelligence (AI) program (for example, referred to herein as an “AI / ML model” ) , such as a program that includes a machine learning (ML) model and / or an artificial neural network (ANN) model. The AI / ML model may be deployed at one or more devices 265 (for example, one or more network nodes 210, one or more UEs 220, and / or one or more servers, and / or one or more components of a cloud computing network, among other examples) . For example, in an deployment where AI / ML functionality is performed independently at a device 265, sometimes referred to as “overlay AI / ML” , the AI / ML model (or an instance or portion of the AI / ML model) may be deployed at a UE 220 (for example, at the processing system 240) , a network node 210 (for example, at the processing system 245) , one or more servers, and / or one or more components of a cloud computing network, among other examples. Additionally or alternatively, in a deployment where AI / ML functionality is coordinated between different devices 265, sometimes referred to as “coordinated AI / ML” , or performed at all device and network layers, sometimes referred to as “native AI / ML” , the AI / ML model (or an instance of the AI / ML model) may be deployed at multiple devices 265 (for example, a first portion of the AI / ML model may be deployed at a UE 220 and a second portion of the AI / ML model may be deployed at a network node 210) . In other examples of coordinated AI / ML and / or native AI / ML, a first AI / ML model may be deployed at a UE 220 and a second AI / ML model may be deployed at a network node 210. The AI / ML model (s) may be configured to enhance various aspects of the wireless communication network 200 (for example, to increase privacy, reliability, and / or efficient use of network bandwidth, and / or to reduce latency, among other examples) . For example, the AI / ML model (s) may be trained to identify patterns or relationships in data corresponding to the wireless communication network 200, a device, and / or an air interface, among other examples. The AI / ML model (s) may support operational decisions relating to one or more aspects associated with wireless communications devices, networks, or services.
[0089] Accordingly, in some examples, the AI / ML model (s) may enable AI-as-a-Service (for example, an end-to-end AI / ML service via a user plane) for use cases such as a self-organizing network (SON) , minimization of drive test (MDT) , quality of experience (QoE) , positioning, sensing, predictive mobility, and / or traffic prediction, among other examples. In some examples, AI-as-a-Service use cases may include measurement collection reporting by a UE 220, device selection criteria (for example, according to a geographical area where measurements are to be collected and / or UE capabilities to be used to collected measurements) , and / or reporting configurations (for example, reporting parameters such as location, time, and / or sensor information, among other examples) . Additionally or alternatively, the AI / ML model (s) may enable AI / ML procedures (for example, RAN-triggered service establishment, configuration, inferencing using UE-side and / or network-side models, performance monitoring and / or management, and / or capability signaling, among other examples) . Additionally or alternatively, the AI / ML model (s) may enable RAN-based AI / ML services via one or more application program interfaces (APIs) and / or management interfaces for use cases such as beam management, RRM relaxation, mobility prediction, load prediction, network energy savings, and / or coverage and capacity improvements, among other examples.
[0090] In some aspects, the UE 220 may include a communication manager 250 (e.g., similar to the communication manager 114 and / or the communication manager 118) . As described in more detail elsewhere herein, the communication manager 250 may receive first configuration information indicating one or more first conditions associated with power state transitions for a first radio (e.g., the main radio 275) ; measure, using a second radio (e.g., the LP-WUR 270) while the first radio is configured to operate in a first power state, one or more first signals to obtain first measurement information, wherein the first radio is configured to operate using first frequency resources and the second radio is configured to operate using second frequency resources; and / or perform a first action to either transition the first radio from the first power state to a second power state or to cause the first radio to continue to operate in the first power state, wherein the first action is based on whether the one or more first conditions are satisfied, and wherein the one or more first conditions are satisfied based on the first measurement information. Additionally, or alternatively, the communication manager 250 may perform one or more other operations described herein.
[0091] In some aspects, the network node 210 may include a communication manager 255 (e.g., similar to the communication manager 114 and / or the communication manager 118) . As described in more detail elsewhere herein, the communication manager 255 may transmit first configuration information indicating one or more first conditions associated with power state transitions for a first radio (e.g., the main radio 275) of a UE, wherein the one or more first conditions being met is based on first measurement information that is configured to be obtained via a second radio (e.g., the LP-WUR 270) of the UE; receive the first measurement information; and / or transmit second configuration information indicating one or more second conditions associated with the power state transitions for the first radio of the second network entity, wherein the one or more second conditions are based on the first measurement information. Additionally, or alternatively, the communication manager 255 may perform one or more other operations described herein.
[0092] Fig. 3 is a diagram illustrating an example disaggregated network node architecture 300, in accordance with the present disclosure. One or more components of the example disaggregated network node architecture 300 may be, may include, or may be included in one or more network nodes (such one or more network nodes 210) . The disaggregated network node architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or that can communicate indirectly with the core network 320 via one or more disaggregated control units, such as a non-real-time (Non-RT) RAN intelligent controller (RIC) 350 associated with a Service Management and Orchestration (SMO) Framework 360 and / or a near-real-time (Near-RT) RIC 370 (for example, via an E2 link) . The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via F1 interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 220 via respective RF access links. In some deployments, a UE 220 may be simultaneously served by multiple RUs 340.
[0093] Each of the components of the disaggregated network node architecture 300, including the CUs 310, the DUs 330, the RUs 340, the Near-RT RICs 370, the Non-RT RICs 350, and the SMO Framework 360, may include one or more interfaces or may be coupled with one or more interfaces for receiving or transmitting signals, such as data or information, via a wired or wireless transmission medium.
[0094] In some aspects, the CU 310 may be logically split into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. A CU-UP unit may communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 may be deployed to communicate with one or more DUs 330, as necessary, for network control and signaling. Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. For example, a DU 330 may host various layers, such as an RLC layer, a MAC layer, or one or more PHY layers, such as one or more high PHY layers or one or more low PHY layers. Each layer (which also may be referred to as a module) may be implemented with an interface for communicating signals with other layers (and modules) hosted by the DU 330, or for communicating signals with the control functions hosted by the CU 310. Each RU 340 may implement lower layer functionality. In some aspects, real-time and non-real-time aspects of control and user plane communication with the RU (s) 340 may be controlled by the corresponding DU 330.
[0095] The SMO Framework 360 may support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 360 may support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface, such as an O1 interface. For virtualized network elements, the SMO Framework 360 may interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface, such as an O2 interface. A virtualized network element may include, but is not limited to, a CU 310, a DU 330, an RU 340, a non-RT RIC 350, and / or a Near-RT RIC 370. In some aspects, the SMO Framework 360 may communicate with a hardware aspect of a 4G RAN, a 5G NR RAN, and / or a 6G RAN, such as an open eNB (O-eNB) 380, via an O1 interface. Additionally or alternatively, the SMO Framework 360 may communicate directly with each of one or more RUs 340 via a respective O1 interface. In some deployments, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0096] The Non-RT RIC 350 may include or may implement a logical function that enables non-real-time control and optimization of RAN elements and resources, AI / ML workflows including model training and updates, and / or policy-based guidance of applications and / or features in the Near-RT RIC 370. The Non-RT RIC 350 may be coupled to or may communicate with (such as via an A1 interface) the Near-RT RIC 370. The Near-RT RIC 370 may include or may implement a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions via an interface (such as via an E2 interface) connecting one or more CUs 310, one or more DUs 330, and / or an O-eNB 380 with the Near-RT RIC 370.
[0097] In some aspects, to generate AI / ML models to be deployed in the Near-RT RIC 370, the Non-RT RIC 350 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 370 and may be received at the SMO Framework 360 or the Non-RT RIC 350 from non-network data sources or from network functions. In some examples, the Non-RT RIC 350 or the Near-RT RIC 370 may tune RAN behavior or performance. For example, the Non-RT RIC 350 may monitor long-term trends and patterns for performance and may employ AI / ML models to perform corrective actions via the SMO Framework 360 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies) .

For example, the processing system 110 of the network entity 102, the processing system 112 of the network entity 106, the processing system 245 of the network node 210, the processing system 240 of the UE 220, the CU 310, the DU 330, or the RU 340 may perform or direct operations of, for example, process 700 of Fig. 7, process 800 of Fig. 8, or other processes as described herein (alone or in conjunction with one or more other processors) . Memory of the network node 210 may store data and program code (or instructions) for the network node 210, the CU 310, the DU 330, or the RU 340. In some examples, the memory of the network node 210 may store data relating to a UE 220, such as RRC state information or a UE context. Memory of a UE 220 may store data and program code (or instructions) for the UE 220, such as context information. In some examples, the memory of the UE 220 or the memory of the network node 210 may include a non-transitory computer-readable medium storing a set of instructions for wireless communication. For example, the set of instructions, when executed by one or more processors (for example, of the processing system 110, the processing system 112, the processing system 245, or the processing system 240) of the network entity 102, the network entity 106, the network node 210, the UE 220, the CU 310, the DU 330, or the RU 340, may cause the one or more processors to perform process 700 of Fig. 7, process 800 of Fig. 8, 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.
[0099] In some aspects, a first network entity includes means for receiving first configuration information indicating one or more first conditions associated with power state transitions for a first radio of the first network entity; means for measuring, using a second radio of the first network entity while the first radio is configured to operate in a first power state, one or more first signals to obtain first measurement information, wherein the first radio is configured to operate using first frequency resources and the second radio is configured to operate using second frequency resources; and / or means for performing a first action to either transition the first radio from the first power state to a second power state or to cause the first radio to continue to operate in the first power state, wherein the first action is based on whether the one or more first conditions are satisfied, and wherein the one or more first conditions are satisfied based on the first measurement information. In some aspects, the means for the first network entity to perform operations described herein may include, for example, one or more of communication manager 250, processing system 240, processing system 110, communication manager 114, communication interface 116, processing system 112, communication manager 118, communication interface 120, one or more radios (e.g., the main radio 275 and / or the LP-WUR 270) , one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 902 depicted and described in connection with Fig. 9) and / or a transmission component (for example, transmission component 904 depicted and described in connection with Fig. 9) , among other examples.
[0100] In some aspects, a first network entity includes means for transmitting first configuration information indicating one or more first conditions associated with power state transitions for a first radio of a second network entity, wherein the one or more first conditions being met is based on first measurement information that is configured to be obtained via a second radio of the second network entity; means for receiving the first measurement information; and / or means for transmitting second configuration information indicating one or more second conditions associated with the power state transitions for the first radio of the second network entity, wherein the one or more second conditions are based on the first measurement information. In some aspects, the means for the first network entity to perform operations described herein may include, for example, one or more of communication manager 255, processing system 245, processing system 110, communication manager 114, communication interface 116, processing system 112, communication manager 118, communication interface 120, a radio, one or more RF chains, one or more transceivers, one or more antennas, one or more modems, a reception component (for example, reception component 1002 depicted and described in connection with Fig. 10) , and / or a transmission component (for example, transmission component 1004 depicted and described in connection with Fig. 10) , among other examples.
[0101] Fig. 4 is a diagram illustrating an example 400 of an LP-WUR and an LP-WUS, in accordance with the present disclosure. As shown in Fig. 4, a UE (such as UE 220) may be equipped with a communication system that includes a main radio (illustrated as “MR” ) 405 (e.g., the main radio 275) and an LP-WUR 410 (e.g., the LP-WUR 270) to reduce power consumption and enable low latency. For example, power saving and low latency are often conflicting goals because placing one or more components into a sleep state more often to reduce power consumption also increases latency (e.g., because data cannot be transmitted and / or received while the one or more components are in the sleep state) , and because reducing the time that one or more components spend in a sleep state to reduce latency can lead to increased power consumption. Accordingly, as shown in Fig. 4, the UE may be equipped with the LP-WUR 410, which may be considered a companion receiver that can be used with a main radio 405 to reduce power consumption and latency.
[0102] For example, in some aspects, the UE may generally use the main radio 405 to transmit and / or receive user data, and the main radio 405 may be turned off or operated in a sleep state (e.g., deep sleep, or ultra deep sleep etc. ) unless there is user data to transmit and / or receive (e.g., paging message, random access channel) . Furthermore, the LP-WUR 410 may serve as a simple wakeup receiver for the main radio 405, and the LP-WUR 410 may be active and monitoring for an LP-WUS while the main radio 405 is off or in the sleep state. For example, reference number 415-1 depicts a first state associated with the main radio 405 and the LP-WUR 410 where there is no user data to be provided to the main radio 405. In such cases, the main radio 405 may be off or operated in the sleep state unless there is user data to transmit, and the LP-WUR 410 may monitor for an LP-WUS (for example, continuously, or periodically in monitoring occasions that are separated in time) . Furthermore, reference number 415-2 depicts a second state associated with the main radio 405 and the LP-WUR 410 where there is user data for the main radio 405. In such examples, the LP-WUR 410 may receive an LP-WUS 420 (such as from a network node 210) and may provide a trigger to wake or otherwise activate the main radio 405 based on detecting the LP-WUS 420. Accordingly, the main radio 405 may then transmit and / or receive user data.
[0103] In general, the LP-WUR 410 may consume little power (for example a target power consumption less than 100 microwatts (μW) in the active state) , which may be achieved using simple modulation schemes (for example, OOK) , a narrow bandwidth (for example, less than 5 MHz) , and / or other suitable techniques. In this way, the LP-WUR 410 can be used to reduce the time that the main radio 405 spends in an on state and / or may avoid unnecessarily waking the main radio 405 from the off or sleep state when there is no user data to transmit or receive, which tends to be costly from a power consumption perspective. Further, because the LP-WUR 410 has a low power consumption, the LP-WUR 410 can be used to frequently or continuously perform LP-WUS monitoring, which may improve latency because the main radio 405 can be woken up when there is user data that the main radio 405 needs to receive. For example, the LP-WUR 410 may not suffer from the latency versus power efficiency tradeoff associated with duty cycling schemes, such as DRX. In some examples, an LP-WUS and / or the LP-WUR 410 can be implemented in conjunction with a DRX cycle, such that the UE may not turn on a main radio 405 during on duration of the DRX cycle if the LP-WUR 410 has not received or detected an LP-WUS in association with (e.g., before) the on duration, thereby further reducing power consumption relative to waking up the main radio 405 in an on duration in which the will not receive a PDCCH. Further, in addition to performing LP-WUS monitoring, which may be used for triggering PDCCH monitoring, the LP-WUR 410 may monitor a low power synchronization signal (LP-SS) and / or one or more SSBs for time and frequency tracking and RRM measurement. In this way, by monitoring the LP-SS and / or SSBs, serving cell and / or neighbor cell monitoring can be offloaded from the main radio 405 to the LP-WUR 410 to reduce how often the main radio 405 is woken up, which can further reduce power consumption.
[0104] In some aspects, the LP-WUR 410 may include an OOK WUR (also referred to as an envelope detector (ED) WUR) . An OOK WUR may only detect the amplitude (such as the magnitude) of a received signal. A UE that uses an OOK WUR may detect the phase of a received signal by activating the MR 405.
[0105] In some aspects, the LP-WUR 410 may include an OFDM WUR (which may be referred to as an in-phase and quadrature (IQ) WUR) . An OFDM WUR can detect both the amplitude and phase of a received signal. For example, an OFDM WUR can obtain first information that is modulated onto a signal using OOK modulation, and second information that is modulated onto the signal using phase modulation.
[0106] In some examples, as shown by reference number 425, one application of the LP-WUR 410 is to monitor the LP-WUS 420 for control channel (e.g., PDCCH) monitoring for UEs in the RRC connected state, which can be used to reduce unnecessary control channel monitoring by the main radio 405. For example, as shown in Fig. 4, the LP-WUR 410 may be configured to monitor for an LP-WUS 420 (while the main radio 405 is off or in a sleep state) according to a wakeup signal (WUS) monitoring periodicity. For example, the LP-WUR 410 may monitor for the LP-WUS 420 in periodic LP-WUS monitoring occasions that are spaced in time according to the WUS monitoring periodicity. Alternatively, although not explicitly shown in Fig. 4, the LP-WUR 410 may be configured to continuously monitor for the LP-WUS 420. In general, a network node may transmit an LP-WUS 420 to a UE only in cases where there is a control channel message that needs to be sent to the UE while the UE is in an active state (such as an RRC connected state) . In such examples, as shown by reference number 430, the LP-WUR 410 may receive and detect the LP-WUS 420, which may trigger the LP-WUR 410 to wake up the main radio 405. In some aspects, the LP-WUS 420 may be a sequence-based WUS, which may include a predefined set of sequences (implemented, for example, using OOK modulation and / or phase modulation) . As shown, the main radio 405 may wake up after a main radio wakeup time, and may then start to monitor one or more PDCCH monitoring occasions (PMOs) (e.g., control channel monitoring occasions) . Otherwise, in cases where the LP-WUR 410 does not detect the LP-WUS 420, the main radio 405 may remain in the sleep state to save power.
[0107] As another example, another application of the LP-WUR 410 is to monitor the LP-WUS 420 for paging monitoring (e.g., while the UE is operating in the RRC idle or inactive state) , which can be used to reduce unnecessary paging reception performed by the main radio 405. For example, as shown in Fig. 4, the LP-WUR 410 may be configured to monitor for an LP-WUS 420 (while the main radio 405 is off or in a sleep state) according to a WUS monitoring periodicity. In general, a network node may transmit an LP-WUS 420 to a UE only in cases where there is a paging PDCCH that needs to be sent to the UE while the UE is in an idle or inactive state (such as an RRC idle or RRC inactive state) . In such examples, as shown by reference number 430, the LP-WUR 410 may receive and detect the LP-WUS 420, which may trigger the LP-WUR 410 to wake up the main radio 405. As shown, the main radio 405 may wake up after a main radio wakeup time, and may then start to monitor one or more SSB transmissions to obtain synchronization with the network node before monitoring and receiving the paging PDCCH in a subsequent paging occasion (PO) . Otherwise, in cases where the LP-WUR 410 does not detect the LP-WUS 420, the main radio 405 may remain in the sleep state to save power.
[0108] In some examples, the UE may not support LP-WUS reception on all frequency bands supported by the UE. For example, the UE may support LP-WUS reception on a subset of frequency bands from a set of frequency bands supported by the UE. As another example, the UE may support reception via the main radio 405 on one or more first frequency bands and reception via the LP-WUR 410 on one or more second frequency bands (e.g., where the one or more first frequency bands and the one or more second frequency bands may or may not include one or more common frequency bands) . For example, the UE may be configured to operate using a first frequency band or a first carrier for the LP-WUR 410 and a second frequency band or a second carrier for the main radio 405. A frequency band refers to a range of frequencies within the electromagnetic spectrum, while a carrier is a single, specific frequency within a frequency band used to transmit or receive signals.
[0109] As described herein, the UE may measure one or more signals using the LP-WUR 410 for time and frequency tracking and RRM measurement. However, RRM measurement information obtained via measurements performed using the LP-WUR 410 may not reflect channel conditions for the main radio 405. For example, because the UE may be configured to operate the LP-WUR 410 and the main radio 405 using different frequency bands or carriers (e.g., the UE may be configured to operate the LP-WUR 410 on a 700 MHz band and the main radio 405 on a 3.5 GHz band) , channel conditions for the main radio 405 and the LP-WUR 410 may vary due to frequency dependent channel effects. Additionally, because the UE may be configured to operate the LP-WUR 410 and the main radio 405 using different frequency bands or carriers, the UE may be configured to communicate with a first cell via the LP-WUR 410 and a second cell via the main radio 405. In some examples, the first cell and the second cell may not be co-located (e.g., network nodes that are configured to support the first cell and the second cell may not be co-located) .
[0110] As a result, measurement information obtained via measurements performed using the LP-WUR 410 may not reliably indicate channel conditions for the main radio 405. Therefore, if the UE uses the measurement information obtained via measurements performed using the LP-WUR 410 for one or more RRM operations for the main radio (such as serving cell and / or neighbor cell monitoring) , then a performance of the one or more RRM operations may be degraded. For example, the UE may not accurately determine when a serving cell channel quality has degraded for the main radio 405. This may result in the UE causing the main radio 405 to wake up or be powered on after the UE has moved outside of a coverage area of the serving cell. This may increase latency associated with camping on a wireless communication network because the UE cannot rely on the RRM measurement performed by the LP-WUR to prepare and / or initiate a handover for the UE (e.g., because the UE may not have turned on the main radio 405 until after the UE is outside of the coverage area of the serving cell) . Therefore, to reliably perform RRM measurements, the UE may use the main radio 405 to perform measurements to obtain RRM measurement information. Without RRM measurement offloading from the main radio to the LP-WUR 410, power savings associated with the use of the LP-WUR 410 may become marginal.
[0111] “Camping” on a cell or network node may refer to the UE monitoring broadcasts from a cell (for example, monitoring a control channel associated with the cell or the network node) to maintain readiness to actively connect with the cell or network node and utilize the wireless communication system. For example, UEs may “camp on” a cell of a wireless communication network and silently monitor or receive periodic broadcasting of signals, such as SIBs and SSBs, without a network node associated with the cell being aware of the camping UE. A UE that has selected a cell and that is monitoring the control channel of the cell is said to be “camped” on the cell.
[0112] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.
[0113] Fig. 5 is a diagram of an example 500 associated with low-power wakeup signal monitoring, in accordance with the present disclosure. As shown in Fig. 5, a first network entity 505 (e.g., the network entity 102, the network entity 104, the network entity 106, the network node 210, a base station, a CU, a DU, and / or an RU) may communicate with a second network entity 510 (e.g., the network entity 102, the network entity 104, the network entity 106, and / or the UE 220) . In some aspects, the first network entity 505 and the second network entity 510 may be part of a wireless network (e.g., the wireless communication network 200 or the environment 100) .
[0114] In some aspects, the second network entity 510 may include a first radio and a second radio. The first radio may be a main radio (e.g., the main radio 275 and / or the main radio 405) . The second radio may be a low-power radio, such as an LP-WUR (e.g., the LP-WUR 270 and / or the LP-WUR 410) . For example, the second network entity 510 may be configured to monitor for signals (e.g., LP-WUSs, low-power synchronization signals, and / or SSBs) via the second radio. The first radio may be associated with (e.g., may be configured to operate in) two or more power states. Different power states may be associated with different energy consumption levels by the first radio. For example, the two or more power states may include a first power state (e.g., in which one or more (or all) components of the first radio are powered off) and a second power state (e.g., in which the one or more (or all) components of the first radio are powered on) . Therefore, the first radio may have a lower energy consumption level when operating in the first power state as compared to the first radio operating in the second power state. The second network entity 510 may be configured to transition the power state of the first radio (e.g., to power on or power off the first radio) of the second network entity 510 based on, in response to, or otherwise associated with receiving or detecting one or more signals via the LP-WUR, in a similar manner as described in more detail elsewhere herein, such as in connection with Figs. 4 and 5. Additionally, as described in more detail elsewhere herein, the second network entity 510 may be configured to perform one or more RRM measurements using the second radio.
[0115] As used herein, the first network entity 505 “outputting” or “transmitting” a communication to the second network entity 510 may refer to a direct transmission (for example, from the first network entity 505 to the second network entity 510) or an indirect transmission via one or more other network nodes or devices, such as one or more TRPs or access nodes. For example, if the first network entity 505 is a DU or an access node controller, an indirect transmission to the second network entity 510 may include the first network entity 505 outputting or transmitting a communication to an RU (e.g., an access node or a TRP) and the RU transmitting the communication to the second network entity 510, or may include causing the RU to transmit the communication (e.g., triggering transmission of a physical layer reference signal) . Similarly, the second network entity 510 “transmitting” a communication to the first network entity 505 may refer to a direct transmission (for example, from the second network entity 510 to the first network entity 505) or an indirect transmission via one or more other network nodes or devices, such as one or more TRPs or access nodes. For example, if the first network entity 505 is a DU or an access node controller, an indirect transmission to the first network entity 505 may include the second network entity 510 transmitting a communication to an RU (e.g., a TRP or an access node) and the RU transmitting the communication to the first network entity 505. Similarly, the first network entity 505 “obtaining” or “receiving” a communication may refer to receiving a transmission carrying the communication directly (for example, from the second network entity 510 to the first network entity 505) or receiving the communication (or information derived from reception of the communication) via one or more other network nodes or devices, such as one or more TRPs or access nodes.
[0116] In some aspects, as shown by reference number 515, the second network entity 510 may optionally transmit, and the first network entity 505 may receive, capability information. The capability information may be included in a capability report. The second network entity 510 may transmit the capability information via an uplink communication, a sidelink communication, a unicast communication, a broadcast communication, a UE assistance information (UAI) communication, a UCI communication, a sidelink control information (SCI) communication, a MAC-CE communication, an RRC communication, a PUCCH, a PUSCH, a sidelink channel (e.g., a physical sidelink control channel (PSCCH) , and / or a physical sidelink shared channel (PSSCH) ) , among other examples. The capability information may indicate one or more parameters associated with respective capabilities of the second network entity 510. The one or more parameters may be indicated via respective information elements (IEs) included in a capability report.
[0117] The capability information may indicate whether the second network entity 510 supports a feature and / or one or more parameters related to the feature. For example, the capability information may indicate a capability and / or parameter for supporting low-power wakeup signaling. In some examples, the capability information may indicate a capability and / or parameter for supporting RRM measurements using the second radio (e.g., using a low-power radio or an LP-WUR) . One or more operations described herein may be based on capability information. For example, the second network entity 510 may perform a communication in accordance with the capability information, or may receive configuration information that is in accordance with the capability information.
[0118] In some aspects, the capability information may indicate support for being configured with one or more conditions for power state transitions of the first radio where the one or more conditions being satisfied is based on measurement information obtained via measurements performed using the second radio. The measurement information may include RRM measurement information. In some aspects, the capability information may indicate one or more first supported frequency bands and / or carriers associated with the second radio. Additionally, the capability information may indicate one or more second supported frequency bands and / or carriers associated with the first radio.
[0119] The first network entity 505 may determine configuration information (e.g., one or more conditions for power state transitions of the first radio) based on, using, or otherwise associated with the capability information. For example, if the capability information indicates that the second network entity 510 supports RRM measurement using the second radio, then the first network entity 505 may determine that the configuration information indicates one or more conditions for power state transitions of the first radio associated with RRM measurement information obtained using the second radio. In other examples, the first network entity 505 may determine the configuration information without, or independent of, the capability information. For example, the first network entity 505 may determine that the second network entity 510 supports obtaining measurement information using the second radio as described herein based on a type, category, or other classification of the second network entity 510.
[0120] As shown by reference number 520, the first network entity 505 may transmit, and the second network entity 510 may receive, configuration information. In some aspects, the second network entity 510 may receive the configuration information via one or more of system information signaling (e.g., a master information block (MIB) and / or a system information block (SIB) , among other examples) , RRC signaling, MAC signaling (e.g., one or more MAC-CEs) , and / or DCI, among other examples.
[0121] In some aspects, the configuration information may indicate one or more candidate configurations and / or communication parameters. In some aspects, the one or more candidate configurations and / or communication parameters may be selected, activated, and / or deactivated by a subsequent indication. For example, the subsequent indication may indicate a candidate configuration and / or communication parameter from the one or more candidate configurations and / or communication parameters. In some aspects, the subsequent indication may include a dynamic indication, such as one or more MAC-CEs and / or one or more DCI messages, among other examples.
[0122] In some examples, the configuration information may not be expressly signaled to the second network entity 510. For example, in some aspects, the configuration information may at least partially be defined by a wireless communication standard, such as the 3GPP. In such examples, the first network entity 505 may not explicitly indicate such configuration information to the second network entity 510. For example, the second network entity 510 may optionally obtain at least a portion of the configuration information from a configuration stored by the second network entity 510 (e.g., an original equipment manufacturer (OEM) configuration) . In some aspects, the configuration information may include a parameter or index that is indicative of information defined, or otherwise fixed, by a wireless communication standard, such as the 3GPP (e.g., rather than explicitly indicating the information) .
[0123] In some aspects, the configuration information may include an LP-WUS configuration. For example, the configuration information may indicate one or more LP-WUS occasions. An LP-WUS occasion may be time domain resources configured to low-power wakeup signals. As used herein, “occasion” may refer to one or more time domain resources configured for (or available for) the communication of one or more signals. For example, an LP-WUS occasion may include one or more time domain resources that are configured for (or available for) the communication of one or more LP-WUSs. As used herein, “time domain resource” may refer to a frame, a subframe, a slot, a mini-slot, one or more symbols (e.g., one or more OFDM symbols or one or more OOK symbols) , a transmission time interval, and / or another time unit.
[0124] The configuration information may indicate first frequency resources (e.g., a first carrier and / or a first frequency band) configured for operation for the first radio of the second network entity 510. For example, the first radio may be configured to operate using the first frequency resources. The configuration information may indicate second frequency resources (e.g., a second carrier and / or a second frequency band) configured for operation for the second radio of the second network entity 510. For example, the second radio may be configured to operate using the second frequency resources. In some aspects, the first frequency resources and the second frequency resources may be different frequency resources (e.g., different carriers and / or different frequency bands) . In other aspects, the first frequency resources and the second frequency resources may at least partially overlap (e.g., may be in the same frequency band and / or may be the same carrier frequency) .
[0125] In some aspects, the second network entity 510 may be configured to communicate with a first cell using the first radio (e.g., the first cell may be referred to as a “main radio cell” ) . The second network entity 510 may be configured to communicate with a second cell using the second radio (e.g., the second cell may be referred to as a “low-power cell” or a “LP-WUR cell” ) . In some aspects, the first cell and the second cell may not be co-located. For example, the first cell may be supported by a first network node (e.g., the first network entity 505, a first network node 210, or another network entity) and the second cell may be supported by a second network node (e.g., a second network node 210, or another network entity) . The first network node and the second network node may not be co-located (e.g., may be positioned in different geographic positions) . The first cell and the second cell may be associated with different coverage areas. In other aspects, the first cell and the second cell may be co-located (e.g., the first network node and the second network node may be co-located (e.g., may be positioned in the same geographic position or may be the same network node) and / or may be associated with the same coverage area) .
[0126] As described in more detail elsewhere herein, RRM measurement information obtained via measurements performed using the second radio of the second network entity 510 may not reflect channel conditions for the first radio of the second network entity 510. For example, because the second network entity 510 may be configured to operate the second radio and the first radio using different frequency bands or carriers, channel conditions for the first radio and the second radio may vary due to frequency dependent channel effects. As a result, measurement information obtained via measurements performed using the second radio may not reliably indicate channel conditions for the first radio. Therefore, if the second network entity 510 uses the measurement information obtained via measurements performed using the second radio for one or more RRM operations (such as serving cell and / or neighbor cell monitoring for the main radio) , then a performance of the one or more RRM operations may be degraded. For example, the second network entity 510 may not accurately determine when a serving cell channel quality has degraded for the first radio.
[0127] Therefore, the first network entity 505 may configure one or more conditions for power state transitions of the first radio. For example, the configuration information may indicate the one or more conditions. In some aspects, the first network entity 505 may configure the one or more conditions such that the one or more conditions being satisfied are indicative of the second network entity 510 being mobile (e.g., is indicative of the second network entity 510 currently moving in a geographic area) .
[0128] As used herein, a condition being “satisfied” may refer to a threshold indicated by the condition being satisfied. Additionally, or alternatively, a condition being “satisfied” may refer to one or more criteria, requirements, expectations, and / or perquisites, among other examples, indicated by the condition being met. Additionally, or alternatively, a condition being “satisfied” may refer to a rule indicated by the condition being fulfilled.
[0129] The one or more conditions may be associated with measurement information. In some aspects, the measurement information may be measurement information that is obtained via the second radio. For example, the one or more conditions may be satisfied based on the measurement information. The measurement information may be RRM measurement information obtained via the second radio while the first radio is configured to operate in the first power state (e.g., in a powered-off state or a sleep state) . For example, the one or more conditions may be applicable when the second network entity 510 causes the first radio to operate in the first power state. Additionally, the one or more conditions may be applicable when the second network entity 510 is operating in an idle or an inactive state (e.g., an RRC idle or an RRC inactive state) .
[0130] In some aspects, the one or more conditions being satisfied may cause the second network entity 510 to transition the power state of the first radio in order to enable the second network entity 510 to make a cell reselection determination. For example, the one or more conditions being satisfied may be indicative of the second network entity 510 being mobile. Therefore, the first network entity 505 may configure the one or more conditions to cause the second network entity 510 to transition the power state of the first radio in order to enable the second network entity 510 to make a cell reselection determination in mobility scenarios. This may enable the second network entity 510 to perform a cell reselection operation before moving outside of a coverage area of a serving cell (e.g., the first cell configured for the first radio) . This may reduce the latency associated with camping on a new serving cell.
[0131] In some aspects, the one or more conditions may indicate or include one or more thresholds. In some aspects, the one or more thresholds may include a threshold for a change in the first measurement information obtained via the second radio. For example, the first network entity 505 may configure a threshold for a change and / or range of measurement information obtained via the second radio. The change can be a positive change (e.g., a change indicative of improved channel conditions) or a negative change (e.g., a change indicative of worsened channel conditions) corresponding to an increase or decrease of one or more values indicated by the measurement information. In other words, the change can be an increase in measurement values or a decrease in measurement values. In some aspects, the one or more thresholds may include a first threshold for an increase in measurement values and a second threshold for a decrease in measurement values. In other aspects, the same threshold may be applicable for both increases and decreases in measurement values indicated by the measurement information.
[0132] For example, a change in measurement information obtained via the second radio may be indicative of the second network entity 510 moving toward a center of the second cell (e.g., configured for the second radio) or away from the second cell. For example, if the change in the measurement information is large enough (e.g., if the change satisfies the threshold (s) indicated by the one or more conditions) , then this may be indicative of the position of the second network entity 510 changing enough that the second network entity 510 should evaluate if a cell reselection operation should be performed by the first radio.
[0133] In some aspects, the measurement information may include raw (e.g., unfiltered) measurement values. Additionally, or alternatively, the measurement information may include filtered measurement values (e.g., that are filtered over multiple measurement occasions) . For example, the configuration information may indicate measurement occasions (e.g., time and / or frequency resources) during which the second network entity 510 is to measure one or more signals (e.g., low-power synchronization signals, SSBs, or other types of signals) using the second radio (e.g., the LP-WUR) . For example, the configuration information may indicate one or more measurement objects configured for measurements using the second radio. The configuration information may indicate that the second network entity 510 is to filter measurement values obtained using the second radio.
[0134] In some aspects, the one or more conditions include one or more mobility conditions of the second network entity 510 indicative of a mobility state of the second network entity 510. The mobility state may indicate a type or category of the mobility of the second network entity 510. For example, the mobility state may include a low mobility state (e.g., indicating that the second network entity 510 is relatively stationary) or a high mobility state (e.g., indicating that the second network entity 510 is moving) . For example, the one or more mobility conditions may be satisfied based on the mobility state of the second network entity 510 indicating low mobility. For example, the configuration information may indicate that the second network entity 510 is to use the measurement information (e.g., obtained using the second radio) to determine if the first radio should transition the power state based on the mobility state of the second network entity 510 indicating low mobility. This is because in high mobility scenarios, the measurement information may change frequently which may result in the second network entity 510 frequently transitioning the power state of the first radio. The frequent transitions of the power state of the first radio may reduce power savings otherwise associated with the use of the second radio. Therefore, the second network entity 510 may be configured to use the measurement information (e.g., obtained using the second radio) to determine if the first radio should transition the power state based on the mobility state of the second network entity 510 indicating low mobility.
[0135] As used herein, “low” mobility may refer to a change in the geographic position of the second network entity 510 not satisfying a mobility threshold for a period of time. For example, the second network entity 510 may have a low mobility state when the second network entity 510 remains in the same general geographic area (e.g., within the coverage area of a given cell) for the period of time. The second network entity 510 may determine the mobility state statistically (e.g., using one or more models, algorithms, or heuristics) and / or dynamically (e.g., using location resolution data, such as GPS data or GNSS data) . For example, the second network entity 510 may determine that the mobility state is the low mobility state based on the second network entity 510 being connected to a cell (e.g., the second cell or the first cell) for an amount of time that satisfies a time threshold (e.g., indicating that the second network entity 510 remains in the same general geographic area) .
[0136] In some aspects, the configuration information may indicate that one or more types of measurement information are to be used to evaluate the one or more conditions. For example, the configuration information may indicate that one or more signal parameters (e.g., a signal strength parameter (such as RSRP) or a signal quality parameter (such as RSRQ) ) are to be used to evaluate the one or more conditions. Additionally, or alternatively, the configuration information may indicate that location resolution measurement information (e.g., obtained via a GPS or GNSS) is to be used to evaluate the one or more conditions. Additionally, or alternatively, the configuration information may indicate that timing information associated with one or more signals (e.g., timing information measured from a low-power synchronization signal after frequency drift is removed) is to be used to evaluate the one or more conditions.
[0137] In some aspects, the configuration information may indicate that the second network entity 510 is to communicate with a third network entity (not shown in Fig. 5) to receive an indication of whether the one or more conditions are satisfied. For example, the second network entity 510 may be configured to transmit measurement information to the third network entity. The third network entity may determine whether the one or more conditions are satisfied based on the measurement information. The third network entity may transmit, and the second network entity 510 may receive, an indication of whether the one or more conditions are satisfied. The third network entity may be a reader (e.g., an ambient-IoT reader) , a roadside unit (RSU) , a TRP, and / or a network node (e.g., a network node 210) , among other examples. By the second network entity 510 communicating with the third network entity to receive an indication of whether the one or more conditions are satisfied, processing resources and / or power resources of the second network entity 510 that would have otherwise been associated with determining whether the one or more conditions are satisfied may be conserved.
[0138] As shown by reference number 525, the second network entity 510 may operate the first radio in the first power state. For example, the second network entity 510 may cause the first radio to operate in the first power state. The first power state may be an off state or a sleep state, as described in more detail elsewhere herein. In some aspects, the second network entity 510 may transition the first radio from operating in the second power state to operating in the first power state.
[0139] As shown by reference number 530, the second network entity 510 may measure, using the second radio, one or more signals to obtain first measurement information. The second network entity 510 may measure the one or more signals while the first radio is operating in the first power state. In some aspects, as described herein, the first radio may be configured to operate using first frequency resources (e.g., a first carrier and / or a first frequency band) and the second radio is configured to operate using second frequency resources (e.g. a second carrier and / or a second frequency band) . The second network entity 510 may measure the one or more signals using the second frequency resources. The one or more signals may be low-power synchronization signals, SSBs, and / or other types of signals.
[0140] The measurement information may indicate one or more values. The one or more values may be signal parameter values. For example, the one or more values may be signal strength values or signal quality values. In some aspects, the one or more values may be RSRP values, RSSI values, RSRQ values, signal-to-noise ratio (SNR) values, among other examples. Additionally, or alternatively, the measurement information may indicate one or more positions or locations of the second network entity 510. For example, the second network entity 510 may estimate or measure the position or location of the second network entity 510 using location resolution information, such as via a GPS or GNSS. Additionally, or alternatively, the measurement information may include timing information of the one or more signals (e.g., timing information of a low-power synchronization signal after frequency drift is compensated) .
[0141] The second network entity 510 may measure the one or more signals during one or more measurement occasions. For example, when the first radio is transitioned to the first power state, the second network entity 510 may transition the second radio to an active state or powered-on state (e.g., for LP-WUS monitoring) . When the second radio is in the active state or powered-on state, the second network entity 510 may measure the one or more signals during the one or more measurement occasions to obtain the measurement information.
[0142] As shown by reference number 535, the second network entity 510 may determine whether the one or more conditions (e.g., for power state transitions of the first radio) are satisfied based on the measurement information. The second network entity 510 may evaluate the one or more conditions (e.g., determine whether the one or more conditions are satisfied) based on the mobility state of the second network entity 510 indicating low mobility, as described elsewhere herein. Additionally, the second network entity 510 may evaluate the one or more conditions based on the second network entity 510 being a type of network entity (e.g., a type of UE) that supports low-power RRM measurements and / or based on the second network entity 510 transmitting an indication of a capability (e.g., in the capability information described in connection with reference number 515) for supporting supports low-power RRM measurements.
[0143] The one or more first conditions may be satisfied based on the measurement information. For example, the measurement information may include a first value (e.g., obtained at a first time or during a first time period) and a second value (e.g., obtained at a second time or during a second time period) . The first value and the second value may be RSRP values, RSRQ values, and / or another signal parameter value. In some aspects, the first value and the second value may be filtered values. For example, the values (e.g., the first value and the second value) may be based on values obtained from multiple measurement occasions and a filter coefficient (e.g., to remove noise and outliers from raw measurement information) .
[0144] In some aspects, the second network entity 510 may be configured with a timer for filtering the measurement information. The timer may indicate a minimum time period over which measurement information is to be filtered. For example, the timer may indicate a quantity of measurement occasions over which measurement information is to be filtered by the second network entity 510. The timer (and / or the quantity of measurement occasions) may improve the likelihood that measurement information used to evaluate the one or more conditions is relatively stable and / or reliable.
[0145] In some aspects, the second network entity 510 may determine whether the one or more conditions are satisfied based on whether a difference between the first value and the second value satisfies a threshold (e.g., indicated by the configuration information) . For example, if the difference between the first value and the second value satisfies the threshold, then the one or more conditions may be satisfied. If the difference between the first value and the second value does not satisfy the threshold, then the one or more conditions may not be satisfied.
[0146] The first value and the second value may be a minimum value and a maximum value indicated by the measurement information during an evaluation period. For example, the second network entity 510 may evaluate the one or more conditions over an evaluation period. The evaluation period may span from the first radio being transitioned from the second power state to the first power state (e.g., the sleep state) until the first radio is transitioned back to the second power state (e.g., the powered-on state) . If a difference between a minimum value and a maximum value indicated by the measurement information obtained during a given evaluation period satisfies the threshold, then the one or more conditions may be satisfied.
[0147] The second network entity 510 may store or collect measurement information during a given evaluation period. The second network entity 510 may use the measurement information obtained during the given evaluation period to determine whether the one or more conditions are satisfied. For example, after transitioning the first radio from the first power state to the second power state, the second network entity 510 may discard any stored or collected measurement information. In other words, the second network entity 510 may not use measurement information obtained during a first evaluation period to determine whether the one or more conditions are satisfied during a second evaluation period.
[0148] In some aspects, the second network entity 510 may receive an indication of whether the one or more conditions are satisfied. For example, the second network entity 510 may transmit the measurement information (e.g., to the first network entity 505 or a third network entity, as described elsewhere herein) . The second network entity 510 may receive the indication of whether the one or more conditions are satisfied based on transmitting the measurement information. For example, another network entity (e.g., the first network entity 505 or the third network entity) may evaluate the one or more conditions based on the measurement information. For example, the other network entity may determine, based on the measurement information, whether there has been a change in the environment, channel, and / or location, among other examples, of the second network entity 510 for which the second network entity 510 should transition the power state of the first radio. The indication of whether the one or more conditions are satisfied may include an indication that the second network entity 510 is to transition the power state of the first radio (e.g., if the one or more conditions are satisfied) or is not to transition the power state of the first radio (e.g., if the one or more conditions are not satisfied) .
[0149] As shown by reference number 540, the second network entity 510 may perform an action for the first radio based on whether the one or more conditions are satisfied (e.g., as determined by the second network entity 510 as described in connection with reference number 535) . The action may include transitioning the first radio from the first power state to the second power state based on the one or more conditions being satisfied. Alternatively, the action may include continuing to operate the first radio in the first power state based on the one or more conditions not being satisfied.
[0150] In some aspects, if the action includes transitioning the first radio from the first power state to the second power state, then the second network entity 510 may evaluate one or more cell reselection conditions (e.g., after transitioning the first radio from the first power state to the second power state) . The second network entity 510 may use the first radio for control channel monitoring (e.g., PDCCH monitoring) and / or RRM measurement after transitioning the first radio to the second power state. For example, if the action includes transitioning the first radio from the first power state to the second power state, then the second network entity 510 may perform one or more measurements using the first radio to obtain measurement information (e.g., first radio measurement information) . The second network entity 510 may determine whether the one or more cell reselection conditions are satisfied using the first radio measurement information. For example, the second network entity 510 may use the first radio measurement information to evaluate the one or more cell reselection conditions because the first radio measurement information may more accurately and / or reliably indicate channel conditions for the first radio.
[0151] If the second network entity 510 determines that the one or more cell reselection conditions are satisfied, then the second network entity 510 may continue to operate the first radio in the second power state (e.g., the powered-on state) . For example, the second network entity 510 may perform a cell reselection operation (e.g., using the first radio) based on the one or more cell reselection conditions being satisfied. The cell reselection operation may include monitoring for, detecting, and / or receiving system information for a neighbor cell (e.g., after cell reselection to the neighbor cell) . For example, the cell reselection operation may include monitoring for, detecting, and / or receiving one or more SIBs of the neighbor cell (e.g., using the first radio) . This may enable the second network entity 510 to camp to the neighbor cell (e.g., while operating in the idle state or the inactive state) with reduced latency (e.g., as compared to the second network entity 510 establishing the connection after moving outside of the coverage area of a current serving cell for the first radio) .
[0152] In some aspects, if the action includes transitioning the first radio from the first power state to the second power state, then the second network entity 510 may transmit measurement information. For example, as shown by reference number 545, the second network entity 510 may transmit, and the first network entity 505 may receive, the measurement information. The measurement information may include the measurement information obtained using the second radio (e.g., as described in connection with reference number 530) . Additionally, or alternatively, the measurement information may include measurement information obtained using the first radio (e.g., that is obtained to evaluate cell reselection condition (s) as described herein) .
[0153] The first network entity 505 may determine updated condition (s) for power state transitions for the first radio based on the measurement information. For example, the first network entity 505 may modify or change one or more conditions and / or thresholds described herein based on the measurement information. For example, as shown by reference number 550, the first network entity 505 may transmit, and the second network entity 510 may receive, updated condition (s) for the power state transitions (e.g., in second configuration information) . The second network entity 510 may receive the updated condition (s) via system information signaling, RRC signaling, MAC signaling, and / or DCI signaling, among other examples. As an example, if the one or more conditions were satisfied based on the measurement information, but the cell reselection condition (s) were not satisfied after transitioning the first radio to the second power state, then the first network entity 505 modify or change one or more conditions and / or thresholds to require a larger change in the measurement information to transition the first radio to the second power state. As another example, if the one or more conditions were satisfied based on the measurement information and the second network entity 510 was already outside of the coverage area of a serving cell after transitioning the first radio to the second power state, then the first network entity 505 modify or change one or more conditions and / or thresholds to require a smaller change in the measurement information to transition the first radio to the second power state. This enables the power usage efficiency of the second network entity 510 to be improved by fine tuning the condition (s) based on measurement information obtained by the second network entity 510.
[0154] In some aspects, if the one or more conditions are not satisfied, then the second network entity 510 may continue to operate the first radio in the first power state. In such examples, the second network entity 510 may perform LP-WUS monitoring and / or RRM measurements using the second radio, as described in more detail elsewhere herein.
[0155] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with respect to Fig. 5.
[0156] Fig. 6 is a diagram of an example 600 associated with low-power wakeup signal monitoring, in accordance with the present disclosure. As shown in Fig. 6, a UE 605 (e.g., the second network entity 510 and / or a UE 220) may be configured to operate in a geographic area. The UE 605 may include a first radio (e.g., a main radio) and a second radio (e.g., a LP-WUR) in a similar manner as described in more detail elsewhere herein. The UE 605 may be configured to operate the second radio with a first cell 610. As shown in Fig. 6, the first cell 610 may be supported by a first network node 615 (e.g., the first network entity 505 and / or a network node 210) . The UE 605 may be configured to operate the first radio with a second cell 620. As shown in Fig. 6, the second cell 620 may be supported by a second network node 625 (e.g., the first network entity 505 and / or a network node 210) .
[0157] The UE 605 may operate with the first radio in a first power state (e.g., a powered-off state or a sleep state, as described in more detail elsewhere herein) . In such examples, the UE 605 may measure one or more signals using the second radio (e.g., in a similar manner as described in connection with Fig. 5 and reference number 530) . For example, the measurement information obtained by the UE 605 during an evaluation period is shown in Fig. 6 via a graph of measurement values over time. As shown in Fig. 6, the UE 605 may be mobile. For example, as shown by reference number 630, the UE 605 may move from a first location (e.g., shown by reference number 605-a) to a second location (e.g., shown by reference number 605-b) .
[0158] As shown in Fig. 6, the measurement information may change as the UE 605 moves from the first location to the second location. For example, the measurement information may indicate a first value 635 while the UE 605 is located at the first location. The measurement information may indicate a second value 640 while the UE is located at the second location (e.g., as shown in Fig. 6, the second value 640 may be greater than the first value 635 because the UE 605 is move toward the first network node 615 that supports the first cell 610) . The first value 635 and the second value 640 may be filtered measurement values based on measurements obtained over multiple measurement occasions (e.g., as shown by the dashed boxes in Fig. 6) . For example, the dashed boxes in Fig. 6 may represent a timer duration and / or a quantity of measurement occasions to be used to determine the filtered measurement values, as described in more detail elsewhere herein.
[0159] As described elsewhere herein, the UE 605 may be configured with one or more conditions for power state transitions of the first radio. As an example, a condition may include a threshold for a change in measurement information obtained using the second radio. For example, if a difference 645 between the first value 635 and the second value 640 satisfies the threshold, then the condition may be satisfied (e.g., and the UE 605 may transition the first radio to a second power state, as described elsewhere herein) . If the difference 645 between the first value 635 and the second value 640 does not satisfy the threshold, then the condition may not be satisfied (e.g., and the UE 605 may continue to operate the first radio in the first power state, as described elsewhere herein) .
[0160] By the UE 605 evaluating the one or more conditions using the measurement information obtained using the second radio, the UE 605 may reliably perform RRM operation (s) while the first radio is in the first power state (e.g., while the main radio of the UE 605 is in a sleep state) . For example, by the UE 605 evaluating the one or more conditions using the measurement information obtained using the second radio, the UE 605 may be enabled to transition the first radio to the second power state and evaluate one or more cell reselection conditions prior to the UE 605 moving outside of the coverage area of the second cell 620.
[0161] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with respect to Fig. 6.

Example process 700 is an example where the apparatus or the first network entity (e.g., the second network entity 510, the network entity 102, the network entity 106, or the UE 220) performs operations associated with low-power wakeup signal monitoring.

For example, the first network entity (e.g., using communication manager 906, depicted in Fig. 9) may perform a first action to either transition the first radio from the first power state to a second power state or to cause the first radio to continue to operate in the first power state, wherein the first action is based on whether the one or more first conditions are satisfied, and wherein the one or more first conditions are satisfied based on the first measurement information, as described above.

[0189] Although Fig. 7 shows example blocks of process 700, in some aspects, process 700 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 7. Additionally, or alternatively, two or more of the blocks of process 700 may be performed in parallel.
[0190] Fig. 8 is a diagram illustrating an example process 800 performed, for example, at a first network entity or an apparatus of a first network entity, in accordance with the present disclosure. Example process 800 is an example where the apparatus or the first network entity (e.g., the first network entity 505, the network entity 102, the network entity 106, or the network node 210) performs operations associated with low-power wakeup signal monitoring.
[0191] As shown in Fig. 8, in some aspects, process 800 may include transmitting first configuration information indicating one or more first conditions associated with power state transitions for a first radio of a second network entity, wherein the one or more first conditions being met is based on first measurement information that is configured to be obtained via a second radio of the second network entity (block 810) . For example, the first network entity (e.g., using transmission component 1004 and / or communication manager 1006, depicted in Fig. 10) may transmit first configuration information indicating one or more first conditions associated with power state transitions for a first radio of a second network entity, wherein the one or more first conditions being met is based on first measurement information that is configured to be obtained via a second radio of the second network entity, as described above.
[0192] As further shown in Fig. 8, in some aspects, process 800 may include receiving the first measurement information (block 820) . For example, the first network entity (e.g., using reception component 1002 and / or communication manager 1006, depicted in Fig. 10) may receive the first measurement information, as described above.
