Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and more particularly to techniques, apparatus and methods for packetization of user equipment for the Internet of Things in the environment. Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of services, including voice, text, messaging, video, data, and / or other services. Services may include unicast, multicast, and / or broadcast services, etc. Typical wireless communication systems employ multiple access radio access technologies (RATs) capable of supporting communication with multiple users by sharing available system resources (e.g., time-domain resources, frequency-domain resources, spatial-domain resources, and / or device transmit power, etc.). 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.

[0003] The aforementioned Multiple Access RATs have been adopted in various telecommunications standards to provide a common protocol enabling different wireless communication devices to communicate at the city, national, regional, or global level. An example telecommunications standard is New Radio (NR). NR (also known as 5G) is part of the continuous evolution of mobile broadband announced by the 3rd Generation Partnership Project (3GPP). NR (and other mobile broadband evolutions beyond NR) can be designed to better support the Internet of Things (IoT) and reduced-capacity device deployments, industrial connectivity, millimeter-wave (mmWave) expansion, licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelinks and other device-to-device direct communication technologies (e.g., cellular vehicle-to-everything (CV2X) communications), massive MIMO, decomposed network architectures and network topology expansion, multi-subscriber implementations, high-precision positioning and / or radio frequency (RF) sensing, and more. As the demand for mobile broadband access continues to grow, further improvements to NR can be implemented, and other radio access technologies (such as 6G) can be introduced to further advance mobile broadband evolution.

[0028] Various aspects of this disclosure are described below with reference to the accompanying drawings. However, aspects of this disclosure may be embodied in many different forms and should not be construed as limited to any specific aspect illustrated or described with reference to the drawings or otherwise presented in this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, various combinations or numbers of aspects set forth herein may be used to implement an apparatus or a practice. Furthermore, the scope of this disclosure is intended to cover apparatuses having structures and / or functionalities other than those available for practicing the various aspects of this disclosure set forth herein, or methods practiced using these other structures and / or functionalities. Any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0029] Various methods, operations, apparatuses, and techniques will now be presented with reference to them. These methods, operations, apparatuses, and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the system as a whole.

[0030] Some wireless communication devices can be considered Internet of Things (IoT) devices, such as environmental IoT devices (sometimes referred to as ultralight IoT devices) or similar IoT devices. In environmental IoT, user equipment (UE) (e.g., radio frequency identification (RFID) devices, tags, or similar devices) may not include batteries, and the UE can accumulate energy from radio signaling. Alternatively, the UE may include batteries and may be designed to achieve low power consumption (e.g., in the range of hundreds of microwatts). To achieve further cost reductions and zero-power or low-power communication, wireless networks may utilize a type of environmental IoT device known as an "environmental backscattering device" or "backscattering device."

[0031] Different environmental IoT devices can have different transmit and receive capabilities, meaning they can transmit at different power levels, for different durations, and so on. Furthermore, a large number of environmental IoT devices can lead to transmission conflicts. Static grouping of environmental IoT devices (e.g., based on device type or static capabilities) can help address these issues by allowing a specific group of environmental IoT devices to be activated or to communicate with that group at a given time. However, the transmit and receive capabilities of environmental IoT devices can vary over time. For example, even for a single environmental IoT device, its transmit and receive capabilities can change with variations in its energy state, channel conditions, etc. Therefore, a statically configured group assigned to an environmental IoT device may become undesirable for that device, such as due to changes in the number of devices assigned to that group, changes in the device's capabilities, or similar situations.

[0032] This disclosure relates in general to grouping environmental IoT devices. Some aspects more specifically relate to dynamically reassigning groups to environmental IoT devices. In some aspects, environmental IoT devices may belong to a first group (which may be, for example, a statically or dynamically configured group). Environmental IoT devices may receive an instruction regarding being assigned to a second group. Environmental IoT devices may communicate according to this instruction. For example, environmental IoT devices may send random access messages or messages associated with inventory actions as part of the second group.

[0033] In some aspects, the indication may be carried in the payload of a physical or media access control layer message. Alternatively, the indication may be based on a sequence, such as a sequence used to generate reference signals or other signals (via multicast, broadcast, or unicast signaling). In some aspects, the indication may be provided after initial access to an environmental IoT device. In some aspects, network nodes may be configured with conditions for switching from a first group to a second group (e.g., the indication may be a configuration indicating such conditions).

[0034] The aspects of this disclosure can be used to achieve one or more of the following potential advantages. In some aspects, dynamic grouping can be achieved by providing indications regarding the switching of ambient IoT devices to a second group. Dynamic grouping of ambient IoT devices can be associated with various benefits, such as grouping devices in a low-energy state to perform earlier access or use a longer sleep duration, or redistributing groups of ambient IoT devices to reduce collisions in random access or other communications. Using a sequence to indicate group switching reduces overhead compared to other methods. Using a payload to indicate group switching increases the flexibility of group switching compared to other methods. Providing a switching indication after initial access enables grouping based on the results of the initial access (such as grouping ambient IoT devices that succeeded at initial access for further communication), which reduces the impact of ambient IoT devices failing at initial access. Configuring conditions for switching reduces dynamic signaling overhead compared to explicitly signaling the switching group.

[0035] Multiple access radio access technology (RAT) has been adopted in various telecommunications standards to provide a common protocol that enables wireless communication devices to communicate at the city, enterprise, national, regional, or global level. For example, 5G New Radio (NR) is part of the continuous mobile broadband evolution program released by the 3rd Generation Partnership Project (3GPP). 5G NR supports a variety of technologies and use cases, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), millimeter wave (mmWave) technology, beamforming, network slicing, edge computing, IoT connectivity and management, and network function virtualization (NFV).

[0036] With increasing demand for broadband access and the evolution of technologies supported by wireless communication networks, further technological improvements can be adopted in or implemented for 5G NR or future RATs (such as 6G) to further advance the evolution of wireless communication for a variety of existing and new use cases and applications. These technological improvements can be associated with new frequency band extensions, licensed and unlicensed spectrum access, overlapping spectrum use, small cell deployments, non-terrestrial network (NTN) deployments, decomposed network architectures and network topology extensions, device aggregation, advanced duplex communication, sidelinks and other device-to-device direct communication, IoT (including passive or ambient IoT) networks, reduced-capacity (RedCap) UE functionality, industrial connectivity, multi-subscriber implementations, high-precision positioning, radio frequency (RF) sensing and / or artificial intelligence or machine learning (AI / ML), and more. Such technological improvements can support use cases such as wireless backhaul, wireless data centers, extended reality (XR) and metaverse applications, meta-services for supporting vehicle connectivity, holographic and mixed reality communications, autonomous and collaborative robots, vehicle platooning and collaborative manipulation, sensor networks, posture monitoring, brain-computer interfaces, digital twin applications, asset management, and general coverage applications using off-ground and / or aerial platforms, etc. The methods, operations, apparatuses, and techniques described herein can implement one or more of the foregoing technologies and / or support one or more of the foregoing use cases.

[0037] Figure 1 This is a diagram illustrating an example of a wireless communication network 100 according to the present disclosure. The wireless communication network 100 may be a 5G (or NR) network or a 6G network, or may include elements of a 5G (or NR) network or a 6G network, etc. The wireless communication network 100 may include a plurality of network nodes 110, shown as network node (NN) 110a, network node 110b, network node 110c, and network node 110d. Network nodes 110 may support communication with a plurality of UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e).

[0038] Network nodes 110 and UEs 120 of wireless communication network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, carriers, and / or channels according to frequency or wavelength. For example, devices of wireless communication network 100 can communicate using one or more operating frequency bands. In some aspects, multiple wireless communication networks 100 can be deployed in a given geographical area. Each wireless communication network 100 can support a specific RAT (which may also be referred to as an air interface) and can operate on one or more carrier frequencies in one or more frequency ranges. Examples of RATs include 4G RATs, 5G / NRRATs, and / or 6G RATs, etc. In some examples, when multiple RATs are deployed in a given geographical area, each RAT in that geographical area can operate on a different frequency to avoid interference with each other.

[0039] Various operating frequency bands have been defined as frequency ranges designated FR1 (410 MHz to 7.125 GHz), FR2 (24.25 GHz to 52.6 GHz), FR3 (7.125 GHz to 24.25 GHz), FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Although a portion of FR1 is greater than 6 GHz, in some documents and articles, FR1 is often (interchangeably) referred to as the “sub-6 GHz” band. Similarly, in some documents and articles, FR2 is often (interchangeably) referred to as the “millimeter wave” band, but this is different from the Very High Frequency (EHF) band (30 GHz to 300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). The frequencies between FR1 and FR2 are often referred to as the mid-band frequencies, including FR3. Frequency bands falling within FR3 can inherit FR1 or FR2 characteristics, thereby effectively extending the characteristics of FR1 or FR2 into mid-band frequencies. Therefore, "below 6 GHz" (if used herein) can broadly refer to frequencies less than 6 GHz, within FR1, and / or included in mid-band frequencies. Similarly, the term "millimeter wave" (if used herein) can broadly refer to frequencies included in mid-band frequencies, within FR2, FR4, FR4-a, FR4-1, or FR5, and / or within the EHF band. Higher frequency bands can extend 5G NR operation, 6G operation, and / or other RATs above 52.6 GHz. For example, each of FR4a, FR4-1, FR4, and FR5 falls within the EHF band. In some examples, the wireless communication network 100 can implement dynamic spectrum sharing (DSS), where multiple RATs (e.g., 4G / LTE and 5G / NR) are implemented within a single frequency band using dynamic bandwidth allocation (e.g., based on user demand). It is conceivable that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1 and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0040] Network node 110 may include one or more devices, components, or systems that enable communication between UE 120 and one or more devices, components, or systems of wireless communication network 100. Network node 110 may be, may include, or may also be referred to as an NR network node, 5G network node, 6G network node, node B, eNB, gNB, access point (AP), transmit / receive point (TRP), mobility element, core, network entity, network element, network equipment, and / or another type of device, component, or system included in a radio access network (RAN).

[0041] Network node 110 may be implemented as a single physical node (e.g., a single physical structure) or as two or more physical nodes (e.g., two or more different physical structures). For example, network node 110 may be a device or system implementing a portion of a radio protocol stack, a device or system implementing a complete radio protocol stack (such as a complete gNB protocol stack), or a collection of devices or systems collectively implementing a complete radio protocol stack. For example, and as shown, network node 110 may be an aggregated network node (with an aggregated architecture), meaning that network node 110 can implement a complete radio protocol stack physically and logically integrated within a single node (e.g., a single physical structure) in the wireless communication network 100. For example, aggregated network node 110 may consist of a single standalone base station or a single TRP that uses the complete radio protocol stack to implement or facilitate communication between UE 120 and the core network of wireless communication network 100.

[0042] Alternatively, and also as shown in the figure, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 can realize a radio protocol stack that is physically distributed and / or logically distributed among two or more nodes in the same or different geographic locations. For example, a decomposed network node may have a decomposed architecture. In some deployments, decomposed network node 110 may be used in integrated access and backhaul (IAB) networks, in open radio access networks (O-RAN) (such as network configurations compliant with the O-RAN Alliance), or in virtualized radio access networks (vRAN) (also referred to as cloud radio access networks (C-RAN)) to facilitate scaling by decomposing base station functionality into multiple units that can be deployed independently.

[0043] Network nodes 110 of the wireless communication network 100 may include one or more central units (CUs), one or more distributed units (DUs), and / or one or more radio units (RUs). CUs may host one or more higher-layer control functions, such as Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, and / or Service Data Adaptation Protocol (SDAP) functions, etc. DUs may host one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and / or one or more higher physical (PHY) layers, at least in part, according to functional splits (such as functional splits defined by 3GPP). In some examples, DUs may also host one or more lower PHY layer functions, such as Fast Fourier Transform (FFT), Inverse FFT (iFFT), beamforming, Physical Random Access Channel (PRACH) extraction and filtering, and / or scheduling of resources for one or more UEs 120, etc. RUs may host RF processing functions or lower PHY layer functions, such as FFT, iFFT, beamforming, or PRACH extraction and filtering, etc., according to functional splits (such as lower-layer functional splits). In this type of architecture, each RU can be operated to handle over-the-air (OTA) communications with one or more UE 120s.

[0044] In some aspects, network node 110 may include a combination of one or more CUs, one or more DUs, and / or one or more RUs. Additionally or alternatively, network node 110 may include one or more near real-time (near RT) RAN Intelligent Controllers (RICs) and / or one or more non-real-time (non-RT) RICs. In some examples, CUs, DUs, and / or RUs may be implemented as virtual units, such as Virtual Central Units (VCUs), Virtual Distributed Units (VDUs), or Virtual Radio Units (VRUs), etc. Virtual units may be implemented as virtual network functions, such as those associated with cloud deployments.

[0045] Some network nodes 110 (e.g., base stations, RUs, or TRPs) can provide communication coverage for specific geographic areas. In 3GPP, the term "cell" can refer to the coverage area of ​​network node 110 or to network node 110 itself, depending on the context in which the term is used. Network node 110 can support one or more (e.g., three) cells. In some examples, network node 110 can provide communication coverage for macro cells, pico cells, femto cells, or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femto cell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femto cell (e.g., UE 120 in a Closed Subscriber Group (CSG)). A network node 110 used for a macro cell may be referred to as a macro network node. Network node 110 used for a picocell may be referred to as a pico network node. Network node 110 used for a femtocell may be referred to as a femto network node or a home network node. In some examples, the cell may not necessarily be stationary. For example, the geographical area of ​​the cell may move depending on the location of the associated mobile network node 110 (e.g., a train, satellite base station, drone, or NTN network node).

[0046] The wireless communication network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, piconet nodes, femtonet nodes, relay network nodes, aggregation network nodes, and / or decomposition network nodes, etc. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 130a, network node 110b can be a pico network node for pico cell 130b, and network node 110c can be a femto network node for femto cell 130c. Compared to other types of network nodes 110, the various types of network nodes 110 typically transmit at different power levels, serve different coverage areas, and / or have different effects on interference in the wireless communication network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0047] In some examples, network node 110 may be, may include, or operate as a RU, TRP, or base station communicating with one or more UEs 120 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. A "downlink" (or "DL") refers to the communication direction from network node 110 to UE 120, and an "uplink" (or "UL") refers to the communication direction from UE 120 to network node 110. Downlink channels may include one or more control channels and one or more data channels. Downlink control channels may be used to transmit downlink control information (DCI) (e.g., scheduling information, reference signals, and / or configuration information) from network node 110 to UE 120. Downlink data channels may be used to transmit downlink data (e.g., user data associated with UE 120) from network node 110 to UE 120. Downlink control channels may include one or more physical downlink control channels (PDCCH), and downlink data channels may include one or more physical downlink shared channels (PDSCH). The uplink channel may similarly include one or more control channels and one or more data channels. The uplink control channel can be used to transmit uplink control information (UCI) from UE 120 to network node 110 (e.g., transmitting corresponding reference signals and / or feedback with one or more downlinks). The uplink data channel can be used to transmit uplink data (e.g., user data associated with UE 120) from UE 120 to network node 110. The uplink control channel may include one or more physical uplink control channels (PUCCH), and the uplink data channel may include one or more physical uplink shared channels (PUSCH). The downlink and uplink may each include a set of resources on which network node 110 and UE 120 can communicate.

[0048] Downlink and uplink resources may include time-domain resources (frames, subframes, time slots, and / or symbols), frequency-domain resources (bands, component carriers, subcarriers, resource blocks, and / or resource elements), and / or spatial-domain resources (specific transmission directions and / or beam parameters). Frequency-domain resources in some bands may be subdivided into bandwidth portions (BWPs). A BWP may be a contiguous block of frequency-domain resources allocated to one or more UEs 120 (e.g., a contiguous block of resource blocks). A UE 120 may be configured with both an uplink BWP and a downlink BWP (where the uplink BWP and downlink BWP may be the same BWP or different BWPs). BWPs may be dynamically configured and / or reconfigured (e.g., by sending DCI configuration to one or more UEs 120 via network node 110), meaning that BWPs may be adjusted in real-time (or near real-time) based on changing network conditions in the wireless communication network 100 and / or based on the specific requirements of one or more UEs 120. This allows for more efficient use of available frequency domain resources in the wireless communication network 100, as fewer frequency domain resources can be allocated to the BWP for UE 120 (which reduces the number of frequency domain resources that UE 120 needs to monitor), thus allowing more frequency domain resources to be distributed across multiple UE 120s. Therefore, the BWP can also assist in the implementation of such UE 120s by facilitating the configuration of smaller bandwidths for communications performed by lower-capacity UE 120s.

[0049] As described above, in some aspects, the wireless communication network 100 may be an IAB network, may include an IAB network, or may be included in an IAB network. In an IAB network, at least one network node 110 is an anchor network node communicating with a core network. The anchor network node 110 may also be referred to as an IAB donor (or "IAB donor"). The anchor network node 110 may be connected to the core network via a wired backhaul link. For example, the Ng interface of the anchor network node 110 may terminate at the core network. Additionally or alternatively, the anchor network node 110 may be connected to one or more devices in the core network that provide core access and mobility management functions (AMF). An IAB network typically also includes multiple non-anchor network nodes 110, which may also be referred to as relay network nodes or simply IAB nodes (or "IAB-nodes"). Each non-anchor network node 110 can directly communicate with the anchor network node 110 via a wireless backhaul link to access the core network, or can indirectly communicate with the anchor network node 110 via one or more other non-anchor network nodes 110 and an associated wireless backhaul link forming a backhaul path to the core network. Some anchor network nodes 110 or other non-anchor network nodes 110 can also directly communicate with one or more UEs 120 via a wireless access link carrying access services. In some examples, network resources used for wireless communication (such as time resources, frequency resources, and / or spatial resources) can be shared between the access link and the backhaul link.

[0050] In some examples, any network node 110 relaying communication may be referred to as a relay network node, a relay station, or simply a repeater. A repeater may receive communications from an upstream station (e.g., another network node 110 or UE 120) and transmit communications to a downstream station (e.g., UE 120 or another network node 110). In this case, the wireless communication network 100 may include or be referred to as a "multi-hop network." Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. Additionally or alternatively, UE 120 can be a relay station capable of relaying transmissions to or from other UE 120s, or can operate as such a relay station. UE 120 relaying communication can be referred to as a UE repeater or relay UE, etc.

[0051] UE 120 may be physically distributed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. UE 120 may be, may include, an access terminal, another terminal, a mobile station, or a subscriber unit, or may be included in an access terminal, another terminal, a mobile station, or a subscriber unit. UE 120 may be, or may include, a cellular phone (e.g., a smartphone), 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband and / or smart jewelry (such as a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), an XR device, a vehicle component or sensor, a smart meter or sensor, industrial manufacturing equipment, a Global Navigation Satellite System (GNSS) device (such as a Global Positioning System device or another type of positioning device), a UE function of a network node, and / or any other suitable device or function that can communicate via a wireless medium, or may be coupled to them.

[0052] UE 120 and / or network node 110 may include one or more chips, system-on-a-chip (SoC), chipsets, packages, or devices that individually or collectively constitute or include a processing system. The processing system includes processor (or “processing”) circuitry in the form of one or more processors, microprocessors, processing units (such as central processing units (CPUs), graphics processing units (GPUs), neural processing units (NPUs), and / or digital signal processors (DSPs)), processing blocks, application-specific integrated circuits (ASICs), programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)), or other discrete gate or transistor logic components or circuits (all of which are generally referred to herein individually as “processors” or collectively as “processors” or “processor circuitry”). One or more of these processors may be individually or collectively configured to perform the various functions or operations described herein. A group of processors that can be configured or configured to perform a set of functions may include a first processor that can be configured or configured to perform a first function in the set, and a second processor that can be configured or configured to perform a second function in the set, or may include the entire group of processors that are configured or configured to perform the set of functions.

[0053] The processing system may also include memory circuitry in the form of one or more memory devices, memory blocks, memory elements, or other discrete gate or transistor logic components or circuits, each of which may include tangible storage media such as random access memory (RAM) or read-only memory (ROM) or combinations thereof (all of which are generally referred to herein individually as "memory" or collectively as "memory" or "memory circuitry"). One or more of these memories may be coupled to one or more processors in the processor (e.g., operatively coupled, communicatively coupled, electronically coupled, or electrically coupled) and may store processor-executable code (such as software) individually or collectively, which, when executed by one or more processors in the processor, may configure one or more processors in the processor to perform the various functions or operations described herein. Additionally or alternatively, in some examples, one or more processors in the processor may be pre-configured to perform the various functions or operations described herein without being configured by software. The processing system may also include or be coupled to one or more modems (such as Wi-Fi (e.g., IEEE compliant) modems or cellular (e.g., 3GPP 4G LTE, 5G, or 6G compliant) modems). In some embodiments, one or more processors of the processing system include or implement one or more modems among the modems. The processing system may also include, or be coupled to, multiple radio components (collectively, “radio components”), multiple RF chains, or multiple transceivers, each of which may in turn be coupled to one or more antennas among multiple antennas. In some embodiments, one or more processors of the processing system include or implement one or more of the radio components, RF chains, or transceivers. UE 120 may be included or may be contained in a housing that houses components associated with UE 120, including the processing system.

[0054] Some UEs 120 may be considered Machine Type Communication (MTC) UEs, Evolved or Enhanced Machine Type Communication (eMTC) UEs, Further Enhanced eMTC (feMTC) UEs, or Enhanced feMTC (efeMTC) UEs, or further evolutions thereof, all of which may be collectively referred to as "MTC UEs". MTC UEs may be, may include, or may be included in or coupled with the following: robots, unmanned aerial vehicles, remote devices, sensors, instruments, monitors, and / or location tags. Some UEs 120 may be considered IoT devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. IoT UEs or NB-IoT devices may be, may include, or may be included in or coupled with the following: industrial machines, appliances, refrigerators, doorbell camera devices, home automation devices, and / or lighting fixtures, etc. Some UEs 120 may be considered customer premises equipment, which may include telecommunications equipment installed at a customer location (such as a home or office) to enable access to a service provider’s network (such as being included in or communicating with the wireless communication network 100).

[0055] Some UEs 120 can be categorized according to different categories associated with varying levels of complexity and / or capabilities. UEs 120 in the first category facilitate large-scale IoT within the wireless communication network 100 and offer lower complexity and / or lower cost compared to UEs 120 in the second category. UEs 120 in the second category may include mission-critical IoT devices capable of URLLC, enhanced mobile broadband (eMBB), and / or precise positioning within the wireless communication network 100, legacy UEs, baseline UEs, high-level UEs, advanced UEs, full-capability UEs, and / or premium UEs. UEs 120 in the third category may have intermediate-level complexity and / or capabilities (e.g., capabilities between those of UEs 120 in the first category and those of UEs 120 in the second category). UEs 120 in the third category may be referred to as reduced-capability UEs (“RedCap UEs”), intermediate-level UEs, NR lightweight UEs, and / or NR simplified UEs, etc. RedCap UEs bridge the gap in capabilities and complexity between NB-IoT devices and / or eMTC UEs and mission-critical IoT devices and / or premium UEs. RedCap UEs can include, for example, wearable devices, IoT devices, industrial sensors, and / or cameras associated with limited bandwidth, power capacity, and / or transmission range. RedCap UEs can support healthcare environments, building automation, power distribution, process automation, transportation and logistics, and / or smart city deployments, among others.

[0056] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly with each other using sidelink communication (e.g., without communicating through a network node 110 acting as an intermediary). As an example, UE 120a can send data, control information, or other signaling directly to UE 120e as sidelink communication. This contrasts with, for example, UE 120a first sending data to network node 110 in UL communication, and then that network node sending data to UE 120e in DL communication. In various examples, UE 120 can use peer-to-peer (P2P) communication protocols, device-to-device (D2D) communication protocols, vehicle-to-everything (V2X) communication protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, and / or vehicle-to-pedestrian (V2P) protocols), and / or mesh network communication protocols to send and receive sidelink communication. In some deployments and configurations, network node 110 may schedule and / or allocate resources for sidelink communication between UEs 120 in the wireless communication network 100. In some other deployments and configurations, UE 120 (instead of network node 110) may perform or cooperate with or negotiate with one or more other UEs to perform scheduling operations, resource selection operations, and / or other operations for sidelink communication.

[0057] In various examples, in addition to half-duplex operation, some network nodes and UEs in the wireless communication network 100, including network node 110 and UE 120, can also be configured for full-duplex operation. Network node 110 or UE 120 operating in half-duplex mode can perform only one of transmission or reception during a specific time resource period (such as a specific time slot, symbol, or other time period). Half-duplex operation may involve time division duplex (TDD), where the DL transmission of network node 110 and the UL transmission of UE 120 do not occur in the same time resource (i.e., the transmissions do not overlap in time). In contrast, network node 110 or UE 120 operating in full-duplex mode can transmit and receive communications concurrently (e.g., within the same time resource). By operating in full-duplex mode, network node 110 and / or UE 120 can generally increase the capacity of the network and radio access links. In some examples, full-duplex operation may involve frequency division duplex (FDD), in which network node 110 performs DL transmission in a first frequency band or on a first component carrier, and UE 120 performs transmission in a second frequency band or on a second component carrier, the second frequency band or the second component carrier being different from the first frequency band or the first component carrier, respectively. In some examples, full-duplex operation may be enabled for UE 120 but not for network node 110. For example, UE 120 may simultaneously transmit UL to the first network node 110 and receive DL transmissions from the second network node 110 in the same time resources. In some other examples, full-duplex operation may be enabled for network node 110 but not for UE 120. For example, network node 110 may simultaneously transmit DL to the first UE 120 and receive UL transmissions from the second UE 120 in the same time resources. In some other examples, full-duplex operation may be enabled for both network node 110 and UE 120.

[0058] In some examples, UE 120 and network node 110 can perform MIMO communication. "MIMO" generally refers to the simultaneous transmission or reception of multiple signals (such as multiple layers or multiple data streams) using the same time and frequency resources. MIMO techniques typically utilize multipath propagation. MIMO can be implemented using various spatial processing or spatial multiplexing operations. In some examples, MIMO can support simultaneous transmission to multiple receivers, which is called multi-user MIMO (MU-MIMO). Some RATs can employ advanced MIMO techniques such as mTRP operations (including redundant transmission or reception on multiple TRPs), reciprocity in the time or frequency domain, single-frequency network (SFN) transmission, or noncoherent joint transmission (NC-JT).

[0059] In some respects, (in combination) Figure 4The described environmental IoT device may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive an instruction regarding the environmental IoT device being assigned to a second group, wherein the environmental IoT device was assigned to a first group prior to receiving the instruction; and may communicate in accordance with the instruction. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0060] In some respects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may send instructions regarding the assignment of an environmental IoT device to a second group, wherein the environmental IoT device was previously assigned to a first group; and communicate in accordance with such instructions. Additionally or alternatively, communication manager 150 may perform one or more other operations described herein.

[0061] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0062] Figure 2 This is a diagram illustrating an example network node 110 communicating with an example UE 120 in a wireless network according to the present disclosure.

[0063] like Figure 2 As shown, network node 110 may include a data source 212, a transmit processor 214, a transmit (TX) MIMO processor 216, a set of modems 232 (shown as 232a to 232t, where t≥1), a set of antennas 234 (shown as 234a to 234v, where v≥1), a MIMO detector 236, a receive processor 238, a data sink 239, a controller / processor 240, a memory 242, a communication unit 244, a scheduler 246, and / or a communication manager 150, etc. In some configurations, one or a combination of antennas 234, modems 232, MIMO detectors 236, receive processors 238, transmit processors 214, and / or TX MIMO processors 216 may be included in the transceiver of network node 110. The transceiver may be under the control of and used by one or more processors (such as controller / processor 240), and in some respects, may perform aspects of the methods, procedures and / or operations described herein in conjunction with processor-readable code stored in memory 242. In some respects, network node 110 may include one or more interfaces, communication components and / or other components that facilitate communication with UE 120 or another network node.

[0064] The terms “processor,” “controller,” or “controller / processor” can refer to one or more controllers and / or one or more processors. For example, references to “a / the processor,” “a / the controller / processor,” etc. (in the singular) should be understood as referring to a combination of… Figure 2 The processor described refers to any one or more processors, such as a single processor or a combination of multiple different processors. The reference to "one or more processors" should be understood as a combination of references. Figure 2 Any one or more processors described herein. For example, one or more processors of network node 110 may include transmit processor 214, TX MIMO processor 216, MIMO detector 236, receive processor 238, and / or controller / processor 240. Similarly, one or more processors of UE 120 may include MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, and / or controller / processor 280.

[0065] In some aspects, a single processor can perform all operations described as being performed by one or more processors. In some aspects, a first set of one or more processors can perform a first operation described as being performed by that one or more processors, and a second set of one or more processors can perform a second operation described as being performed by that one or more processors. The processors in the first set and the processors in the second set can be the same set of processors or can be different sets of processors. The reference to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as combined... Figure 2 The memory described. For example, an operation described as being performed by one or more memories can be performed by the same subset of the one or more memories or by different subsets of the one or more memories.

[0066] For downlink communication from network node 110 to UE 120, transmitting processor 214 may receive data (“downlink data”) intended for use by UE 120 (or a set of UEs including UE 120) from data source 212 (such as a data pipeline or data queue). In some examples, transmitting processor 214 may select one or more MCSs for UE 120 based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 may process the data (e.g., including encoding the data) according to the MCS selected for UE 120 for transmission to UE 120 on the downlink, thereby generating data symbols. Transmitting processor 214 may process system information (e.g., semi-static resource partitioning information (SRPI)) and / or control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and / or control symbols. The transmitting processor 214 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS), or channel state information (CSI) reference signals (CSI-RS)) and / or synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)).

[0067] The TX MIMO processor 216 can perform space processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output a set of symbol streams (e.g., T A set of output symbol streams is provided to modem 232. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 232. Each modem 232 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for orthogonal frequency division multiplexing (OFDM)) to obtain an output sample stream. Each modem 232 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain a time-domain downlink signal. Modems 232a to 232t may transmit the set of downlink signals (e.g., via a set of corresponding antennas 234) together. T (One downlink signal).

[0068] Downlink signals may include DCI communication, MAC control element (MAC-CE) communication, RRC communication, downlink reference signals, or another type of downlink communication. Downlink signals may be transmitted on the PDCCH, PDSCH, and / or on another downlink channel. Downlink signals may carry one or more transport blocks (TBs) of data. A TB may be a data unit transmitted via the air interface in the wireless communication network 100. A data stream (e.g., from data source 212) may be encoded into multiple TBs for transmission via the air interface. The number of TBs used to carry data associated with a particular data stream may be associated with a TB size shared by multiple TBs. The TB size may be based on the radio channel conditions of the air interface, the MCS used to encode the data, downlink resources allocated for transmitting data, and / or other parameters, or otherwise associated with them. Generally, a larger TB size allows for a larger amount of data to be transmitted in a single transmission, reducing signaling overhead. However, a larger TB size may be more prone to transmission and / or reception errors than a smaller TB size, but such errors can be mitigated through more robust error correction techniques.

[0069] For uplink communication from UE 120 to network node 110, the uplink signal from UE 120 may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected where applicable by MIMO detector 236 (e.g., receive (Rx) MIMO processor), and / or further processed by receive processor 238 to obtain decoded data and / or control information. Receive processor 238 may provide the decoded data to data sink 239 (which may be a data pipeline, data queue, and / or another type of data sink) and provide the decoded control information to processors such as controller / processor 240.

[0070] Network node 110 may use scheduler 246 to schedule one or more UEs 120 for downlink or uplink communication. In some aspects, scheduler 246 may use DCI to dynamically schedule DL transmissions to and / or UL transmissions from UE 120. In some examples, scheduler 246 may allocate repetitive time-domain and / or frequency-domain resources that UE 120 may use to transmit and / or receive communication using RRC configuration (e.g., semi-static configuration), for example, to perform semi-persistent scheduling (SPS) or to configure configuration grant (CG) for UE 120.

[0071] One or more of the following may be included in the RF chain of network node 110: transmit processor 214, TX MIMO processor 216, modem 232, antenna 234, MIMO detector 236, receive processor 238, and / or controller / processor 240. The RF chain may include one or more filters, mixers, oscillators, amplifiers, analog-to-digital converters (ADCs), and / or other devices for converting analog signals (such as those used for transmission or reception via an air interface) to digital signals (such as those used for processing by one or more processors of network node 110). In some aspects, the RF chain may be a transceiver of network node 110, or may be included in such a transceiver.

[0072] In some examples, network node 110 may use communication unit 244 to communicate with the core network and / or other network nodes. Communication unit 244 may support wired and / or wireless communication protocols and / or connections, such as Ethernet, fiber optic, Common Public Radio Interface (CPRI), and / or wired or wireless backhaul, etc. Network node 110 may use communication unit 244 to send and / or receive data associated with UE 120, or to perform network control signaling, etc. Communication unit 244 may include transceivers and / or interfaces, such as network interfaces.

[0073] UE 120 may include a set of antennas 252 (shown as antennas 252a to 252r, where r ≥ 1), a set of modems 254 (shown as modems 254a to 254u, where u ≥ 1), a MIMO detector 256, a receive processor 258, a data sink 260, a data source 262, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, a memory 282, and / or a communication manager 140, etc. One or more components of UE 120 may be included in housing 284. In some aspects, one or a combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, or TX MIMO processor 266 may be included in a transceiver included in UE 120. The transceiver may be under the control of and used by one or more processors (such as controller / processor 280), and in some respects, may perform aspects of the methods, procedures, or operations described herein in conjunction with processor-readable code stored in memory 282. In some respects, UE 120 may include another interface, another communication component, and / or another component that facilitates communication with network node 110 and / or another UE 120.

[0074] For downlink communication from network node 110 to UE 120, the set of antennas 252 can receive downlink communication or signals from network node 110, and can receive the set of downlink signals (e.g., R Each received signal is provided to a set of modems 254. For example, each received signal may be provided to a corresponding demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use the corresponding demodulator component to condition (e.g., filter, amplify, down-convert, and / or digitize) the received signal to obtain an input sample. Each modem 254 may use the corresponding demodulator component to further demodulate or process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 may obtain the received symbols from the set of modems 254, may perform MIMO detection on the received symbols where applicable, and may provide the detected symbols. Receiver processor 258 may process (e.g., decode) the detected symbols, may provide the decoded data for UE 120 to data sink 260 (which may include data pipelines, data queues, and / or applications executed on UE 120), and may provide the decoded control information and system information to controller / processor 280.

[0075] For uplink communication from UE 120 to network node 110, the transmitting processor 264 may receive and process data (“uplink data”) from data source 262 (such as data pipelines, data queues, and / or applications running on UE 120) and control information from controller / processor 280. The control information may include one or more parameters, feedback, one or more signal measurements, and / or other types of control information. In some aspects, the receiving processor 258 and / or controller / processor 280 may determine one or more parameters related to the transmission of uplink communication for received signals (such as those received from network node 110 or another UE). One or more parameters may include a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, a CQI parameter, or a Transmit Power Control (TPC) parameter, etc. The control information may include indications of the RSRP parameter, RSSI parameter, RSRQ parameter, CQI parameter, TPC parameter, and / or another parameter. Control information can facilitate parameter selection and / or scheduling for UE 120 by network node 110.

[0076] Transmit processor 264 can generate reference symbols for one or more reference signals, such as uplink DMRS, uplink sounding reference signal (SRS), and / or another type of reference signal. Symbols from transmit processor 264 can be pre-decoded by TX MIMO processor 266 where applicable, and further processed by a set of modems 254 (e.g., for DFT-s-OFDM or CP-OFDM). TX MIMO processor 266 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and can output symbol streams (e.g., U A set of output symbol streams is provided to a set of modems 254. For example, each output symbol stream may be provided to a corresponding modulator component (shown as MOD) of modem 254. Each modem 254 may use the corresponding modulator component to process (e.g., modulate) the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 254 may further use the corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream to obtain an uplink signal.

[0077] Modems 254a to 254u can transmit uplink signal sets (e.g., via a set of corresponding antennas 252) R One uplink signal or U Uplink signals may include UCI communication, MAC-CE communication, RRC communication, or another type of uplink communication. Uplink signals may be transmitted on PUSCH, PUCCH, and / or another type of uplink channel. Uplink signals may carry one or more TBs of data. Sidelink data and control transmission (i.e., transmissions made directly between two or more UEs 120) may typically use techniques similar to those described for uplink data and control transmission, and may use sidelink-specific channels such as the Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), and / or Physical Sidelink Feedback Channel (PSFCH).

[0078] One or more antennas in the set of antennas 252 or the set of antennas 234 may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc., or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or with one or more transmitting or receiving components (such as...) Figure 2 An antenna module is a combination of one or more antenna elements coupled to one or more components. As used herein, "antenna" can mean one or more antennas, one or more antenna panels, one or more antenna groups, one or more collections of antenna elements, or one or more antenna arrays. "Antenna panel" can mean a group of antennas (such as antenna elements) arranged in an array or panel that can facilitate beamforming by manipulating the parameters of that group of antennas. "Antenna module" can mean a circuit that includes one or more antennas, and may also include one or more other components (such as filters, amplifiers, or processors) associated with integrating the antenna module into a wireless communication device.

[0079] In some examples, each antenna element of antenna 234 or antenna 252 may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. Antenna elements may include patch antennas, dipole antennas, and / or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements can allow signals with a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam) in various directions. For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half a wavelength, or another fraction of the wavelength between adjacent antenna elements to allow desired constructive and destructive interference modes of signals transmitted by individual antenna elements within that desired range.

[0080] The amplitude and / or phase of signals transmitted via antenna elements and / or sub-elements can be modulated and (e.g., by manipulating phase shifts, phase offsets, and / or amplitudes) shifted relative to each other to generate one or more beams; this is known as beamforming. The term "beam" can refer to the directional transmission of a wireless signal toward a receiving device or otherwise in a desired direction. "Beam" can also generally refer to the direction associated with such directional signal transmission, the set of directional resources associated with the signal transmission (e.g., angle of arrival, horizontal direction, and / or vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal. In some implementations, antenna elements can be individually selected or deselected for the directional transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers and / or the phase of the signal to form one or more beams. The shape of the beam (such as amplitude, width, and / or the presence of sidelobes) and / or the direction of the beam (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shifts, phase offsets, and / or amplitudes of multiple signals relative to each other.

[0081] Different UEs 120 or network nodes 110 may include different numbers of antenna elements. For example, UE 120 may include a single antenna element, two antenna elements, four antenna elements, eight antenna elements, or different numbers of antenna elements. As another example, network node 110 may include eight antenna elements, 24 antenna elements, 64 antenna elements, 128 antenna elements, or different numbers of antenna elements. Generally speaking, a larger number of antenna elements provides increased control over the parameters used for beamforming compared to a smaller number of antenna elements, while a smaller number of antenna elements may be less complex to implement and can use less power. Multiple antenna elements can support multi-layer transmission, in which the same time and frequency resources are used to utilize spatial multiplexing to transmit a first layer of communication (which may include a first data stream) and a second layer of communication (which may include a second data stream).

[0082] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0083] Figure 3This is an illustration of an example decomposed base station architecture 300 according to the present disclosure. One or more components of the example decomposed base station architecture 300 may be, may include, or may be included in one or more network nodes (such as one or more network nodes 110). The decomposed base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or may communicate indirectly with the core network 320 via one or more decomposed control units (such as non-RT RIC 350 and / or near-RT RIC 370 associated with a Service Management and Orchestration (SMO) framework 360 (e.g., via an E2 link). The CU 310 may communicate with one or more DU 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RU 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UE 120 via a corresponding RF access link. In some deployments, a UE 120 may be served simultaneously by multiple RU 340s.

[0084] Each component of the disassembled base station architecture 300 (including CU 310, DU 330, RU 340, near-RT RIC 370, non-RT RIC 350, and SMO frame 360) may include one or more interfaces or may be coupled to one or more interfaces for receiving or transmitting signals, such as data or information, via wired or wireless transmission media.

[0085] In some respects, the CU 310 can be logically divided into one or more CU user plane (CU-UP) units and one or more CU control plane (CU-CP) units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface such as an E1 interface. The CU 310 can be deployed to communicate with one or more DU 330s for network control and signaling, as needed. Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340s. For example, the DU 330 may host various layers, such as the RLC layer, 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 may also be referred to as a module) can be implemented using an interface for signaling to other layers (and modules) hosted by the DU 330, or for signaling to control functions hosted by the CU 310. Each RU 340 may implement lower-layer functionality. In some respects, the real-time and non-real-time aspects of communication with the control plane and user plane of the RU 340 can be controlled by the corresponding DU 330.

[0086] The SMO framework 360 supports RAN deployment and provisioning for both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 360 supports the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 360 can interact with cloud computing platforms such as the Open Cloud (O-Cloud) platform 390 to perform network element lifecycle management (such as instantiating virtualized network elements) via cloud computing platform interfaces such as the O2 interface. Virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 350, and / or near-RT RIC 370. In some aspects, the SMO framework 360 can communicate with hardware aspects of the 4G RAN, 5G NR RAN, and / or 6G RAN (such as the Open eNB (O-eNB) 380) via the O1 interface. Additionally or alternatively, the SMO framework 360 can communicate directly with each of one or more RUs 340 via the corresponding O1 interface. In some deployments, this configuration enables each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0087] The non-RT RIC 350 may include or implement logic functions that enable non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for 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 communicate with the near-RT RIC 370, such as via an A1 interface. The near-RT RIC 370 may include or implement logic functions that enable near real-time control and optimization of RAN elements and resources via an interface, such as an E2 interface, through data collection and action, connecting one or more CU 310s, one or more DU 330s, and / or O-eNBs to the near-RT RIC 370.

[0088] 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 an external server. This information can be utilized by the near-RT RIC 370 and can be received from non-network data sources or network functions at the SMO framework 360 or the non-RT RIC 350. In some examples, the non-RT RIC 350 or near-RT RIC 370 may modulate RAN behavior or performance. For example, the non-RT RIC 350 may monitor long-term trends and patterns in performance and may employ AI / ML models to perform corrective actions via the SMO framework 360 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0094] Figure 4 This is a diagram illustrating example 400 associated with environmental IoT communication according to this disclosure.

[0095] Some wireless communication devices can be considered IoT devices, such as environmental IoT devices (sometimes referred to as ultralight IoT devices) or similar IoT devices. Environmental IoT technologies can include passive IoT (e.g., NR passive IoT for 5G advanced), semi-passive IoT, or ultralight IoT, etc. In passive IoT, the terminal (e.g., RFID device, tag, or similar device) may not include a battery or other form of energy storage device, and the terminal can accumulate energy from radio signaling. Additionally, the terminal can accumulate solar energy to supplement the accumulated energy from radio signaling. In passive IoT, the communication distance can be up to 30 meters (or longer) to facilitate feasible network coverage over large areas (e.g., 5000 square meters) such as in a warehouse. Furthermore, the power consumption of a passive IoT terminal (e.g., UE) can be less than 0.1 milliwatts (mW) to support battery-free operation, and the terminal can be relatively inexpensive to facilitate cost-sensitive use.

[0096] Passive IoT combined with industrial sensors can be useful, as battery replacement can be very difficult or undesirable for industrial sensors (e.g., for security monitoring or fault detection in smart factories, infrastructure, or environments). Additionally, the characteristics of passive IoT devices, such as low cost, small size, maintenance-free operation, durability, and long lifespan, can facilitate smart logistics / warehousing (e.g., combined with automated asset management via RFID tag replacement). Furthermore, passive IoT can be combined with smart home networks for home appliance management, wearable devices (e.g., wearables for medical monitoring of patients that do not require battery replacement), and / or environmental monitoring. To achieve further cost reductions and zero-power communication, 5G+ / 6G wireless networks can utilize a type of environmental IoT device known as an "ambient backscatter device" or "backscatter device."

[0097] like Figure 4As shown, a backscattering device 405 (e.g., a tag, sensor, etc.), which may be an example of an environmental IoT device, may employ a simplified hardware design (e.g., including a power divider, energy harvester, and microcontroller). This hardware design does not include a battery, allowing the backscattering device 405 to rely on energy harvesting for power, and does not include radio wave generation circuitry, enabling the backscattering device 405 to transmit information solely by reflecting radio waves. More specifically, the backscattering device 405 communicates with a reader 408 (e.g., UE 120, network node 110, or another network device) by modulating reflected radio signals from an RF source 410 (e.g., network node 110, UE 120, or another network device). In some examples, the RF source 410 and the reader 408 may be the same device and / or may be co-located. For example, in some cases, the reader 408 and the RF source 410 may be associated with the same network node 110.

[0098] To facilitate communication between the backscattering device 405 and the backscattering device 405, the RF source 410 may transmit an energy harvesting wave to the backscattering device 405. The energy harvesting wave may be transmitted for a sufficient duration to achieve a communication phase within the target range between the reader 408 and the backscattering device 405. Additionally or alternatively, in some cases, the range between the RF source 410 and the backscattering device 405 may be limited by a minimum received power, such as -20 dBm, to trigger energy harvesting at the backscattering device 405.

[0099] Once sufficient energy has accumulated at backscattering device 405, backscattering device 405 can begin reflecting radio waves radiated to it via backscattering link 415. For example, RF source 410 can initiate a communication session with a query (sometimes referred to as query-response communication), which can be a modulated envelope of a continuous wave (CW). Backscattering device 405 can respond by backscattering the CW. The communication session can include multiple rounds, such as for contention resolution purposes when multiple backscattering devices respond to a query. The channel between RF source 410 and backscattering device 405 in backscattering link 415 can be associated with a first backscattering link channel response value (sometimes referred to as a first backscattering link channel coefficient or first backscattering link gain value) hBD. As described below, backscattering device 405 can have reflection on and reflection off periods that follow at least in part based on the pattern of information bits transmitted by backscattering device 405. Reader 408 can detect the reflection pattern of backscattering device 405 and obtain backscattering communication information via backscattering link 415. The channel between the reader 408 and the backscattering device 405 of the backscattering link 415 can be associated with a second backscattering link channel response value (sometimes referred to as the second backscattering link channel coefficient or the second backscattering link channel gain value) hDU. Furthermore, the RF source 410 and the reader 408 can communicate (e.g., reference signals and / or data signals) via the direct link 420. The channel between the RF source 410 and the reader 408 of the direct link 420 can be associated with a direct link channel response value (sometimes referred to as the direct link channel coefficient or the direct link channel gain value) hBU.

[0100] The backscattering device 405 can use information modulation schemes such as amplitude shift keying (ASK) modulation or on / off keying (OOK) modulation. For ASK or OOK modulation, the backscattering device 405 can turn on reflection when transmitting an information bit "1" and turn off reflection when transmitting an information bit "0". In backscatter communication, the RF source 410 can transmit a specific radio wave (e.g., a reference signal or data signal, such as PDSCH), which can be represented as x(n). The reader 408 can receive the radio wave x(n) directly from the RF source 410 via a direct link 420, and receive the radio wave from the backscattering device 405, which modulates the radio wave and reflects it to the reader 408, via a backscattering link 415. The signal received at the reader 408 via the direct link 420 (indicated by reference numeral 425) is the product of the radio wave x(n) transmitted by the RF source 410 and the direct link channel response value hBU, plus any signal noise. The information bit signal of the backscattering device 405 can be represented as s(n), where s(n) {0,1}. Therefore, the signal received at reader 408 via backscatter link 415 (indicated by reference numeral 430) is the product of the signal x(n) transmitted by RF source 410 multiplied by the first backscatter link channel response value hBD, the second backscatter link channel response value hDU, the information bit signal s(n) from backscatter device 405, and the reflection coefficient associated with backscatter device 405 plus any noise.

[0101] Therefore, the signal received at reader 408 is a superposition of the signal received via direct link 420 and the signal received via backscatter link 415, which can be represented as y(n). This signal y(n) is indicated by reference numeral 435. As shown, when s(n) = 0 (indicated by reference numeral 440 in the graph shown at reference numeral 430), backscattering device 405 can turn off reflection, and therefore reader 408 receives only the direct link 420 signal. When s(n) = 1 (indicated by reference numeral 445 in the graph shown at reference numeral 430), backscattering device 405 can turn on reflection, and therefore reader 408 receives the superposition of both the direct link 420 signal and the backscatter link 415 signal. In order to receive the information bits transmitted by backscattering device 405, reader 408 can first decode x(n) by treating the backscatter link 415 signal as interference, at least in part based on the direct link channel response value h_BU(n). Then, the reader 408 can detect the presence of the signal component. In some cases, the backscatter device 405 may not maintain the state from communication session to communication session except for the contents stored in the memory of the backscatter device 405, such as the electronic product code (EPC) or similar information associated with the backscatter device 405.

[0102] Some environmental IoT devices can be referred to as semi-passive IoT devices because communication between the reader and the IoT device does not require an energy harvesting waveform as a precondition. For example, a semi-passive IoT device may include a battery or similar energy source that can power the receiver and / or logic circuitry. For such devices, energy harvesting can still be triggered in some situations, such as for long-range communication. In such examples, the rectifier circuitry of the IoT device may have a hot start from a battery or other energy source and can therefore be associated with a lower minimum receive power requirement than that of a passive IoT device (e.g., -30 dBm instead of -20 dBm). However, long-range communication may require battery power consumption to incentivize each decoding. More specifically, for long-range communication where the energy harvesting rate is lower than required by the decoding circuitry, such as when the energy harvesting rate is below -30 dBm, a semi-passive IoT device may consume battery power to incentivize each decoding. Therefore, continuous IoT device monitoring (such as for receiving long-range query communications) can lead to excessive battery consumption at the IoT device.

[0103] For example, passive IoT devices can be associated with low cost and low form factor because no RF chain is required at the IoT device level. However, these devices use energy harvesting waveforms, thus limiting the application of such passive IoT devices to short-range communication. While semi-passive IoT devices can eliminate the need for energy harvesting waveforms and / or enable long-range communication, such devices increase cost and complexity because they require batteries or similar power sources. Furthermore, because passive and semi-passive devices can be associated with communication sessions initiated by RF sources, these devices may inherently limit their use in sensing scenarios or similar latency-critical applications requiring non-periodic operations, and they may not scale well for high-IoT-density applications.

[0104] In some examples, three device types for environmental IoT devices can be defined. These device types may be referred to as Device 1, Device 2a, and Device 2b. Device 1 can perform backscatter communication based on energy storage and energy harvesting. The harvested energy can be stored in the device and later used to power integrated circuits or active RF components. Device 1 can use RF envelope-based detection for downlink reception and backscatter for uplink transmission, and can have a peak power consumption of approximately 1µW. Device 2a can perform backscatter-based communication with energy storage and energy harvesting. The harvested energy can be stored in the device and later used to power integrated circuits or active RF components. Device 2a can use RF envelope-based detection for downlink reception and backscatter for uplink transmission. Receiver or transmitter amplification can be considered to improve sensitivity, and peak power consumption can be in the range of several hundred microwatts. Device 2b can utilize energy storage to actively generate carrier signals. The harvested energy can be stored in the device and later used to power integrated circuits or active RF components. Device 2b can use either a receiver chain based on RF envelope detection (RFED) or a mixer-based method with in-phase and quadrature branches. The latter offers better sensitivity and higher power consumption. The peak power consumption of device 2b is in the range of several hundred milliwatts.

[0105] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0106] Figure 5 This is a diagram illustrating example 500 of signaling for dynamic indication of a group of environmental IoT devices according to this disclosure. Example 500 includes environmental IoT devices (e.g., UE 120, backscattering device 405, or related devices). Figure 4 Another form of environmental IoT device described herein) and network nodes (e.g., UE 120, network node 110, reader 408, RF source 410). In Example 500, as noted above, "network node" may refer to a node of the UE or RAN (such as DU, RU, etc.).

[0107] As shown by reference numeral 510 in the attached figure, in some aspects, network nodes can send configuration information, and environmental IoT devices can receive configuration information.

[0108] In some aspects, configuration information may be associated with sequences used to indicate groups or switch environmental IoT devices. For example, configuration information may include information indicating a mapping between sequences and one or more groups. For instance, a first sequence may be configured to indicate that an environmental IoT device should switch to a first group, and a second sequence may be configured to indicate that an environmental IoT device should switch to a second group (e.g., different switching directions may have different sequences). As another example, sequences may be configured to be associated with a first group and a second group, and may be used to indicate that an environmental IoT device should switch from the first group to the second group or from the second group to the first group. As yet another example, configuration information may indicate the duration associated with a sequence. For instance, configuration information may indicate the group mapped to the sequence, and may indicate the duration of that group. After that duration has elapsed, the environmental IoT device may switch back to the previous group. Therefore, the mapping between sequences and corresponding groups (e.g., group identifiers) can be configured or pre-configured.

[0109] In some respects, configuration information may indicate the duration or conditions associated with assigning a new group (or group identifier). For example, configuration information may indicate the time for receiving the assignment of a new group. For example, configuration information may indicate that a network node may assign a new group identifier only before the network node sends a selection command for an inventory operation or after the inventory operation has ended (e.g., assigning a new group identifier may not be allowed during an inventory operation). As another example, configuration information may indicate one or more durations related to how long an environmental IoT UE should remain in a group. For example, one or more durations may indicate at least one of the following: the minimum time length for which an environmental IoT UE should remain in a given group or the maximum time length for which an environmental IoT UE should remain in a given group.

[0110] As another example, configuration information may indicate thresholds. For instance, configuration information may indicate thresholds related to energy state (e.g., the stored energy level of the environmental IoT device, the energy conversion efficiency of the environmental IoT device, the charging rate of the environmental IoT device, or the discharging rate of the environmental IoT device), the service priority of the environmental IoT device, the group size of the environmental IoT device (e.g., the environmental IoT device may switch groups when the group size is greater than a threshold), latency parameters (e.g., the environmental IoT device may switch groups when the latency requirement of the environmental IoT device is lower than a threshold), signal measurements (e.g., the environmental IoT device may switch groups when RSSI, RSRP, or RSRQ meet thresholds), amplifier status (e.g., the environmental IoT device may switch groups if a power amplifier or low-noise amplifier switches from an on state to an off state or vice versa), or decoding performance (e.g., the environmental IoT device may switch groups if decoding is unsuccessful). Such switching of environmental IoT device groups can be initiated by network nodes (such as using explicit indications of switching) or by the environmental IoT device itself (such as based on configuration information). Therefore, when the triggering conditions identified by the threshold are met, the environmental IoT device can switch groups (e.g., autonomously or in response to a trigger from a network node).

[0111] As indicated by reference numeral 520, in some aspects, the environmental IoT device can send, and the network node can receive, a trigger to switch from a first group to a second group. For example, in some cases, one or more of the trigger conditions described above, related to a configured threshold, can be met. In this example, the environmental IoT device can send a trigger to switch to a new group. Additionally or alternatively, the environmental IoT device can switch to a new group autonomously. For example, in some cases, the trigger can cause the network node to switch the environmental IoT device's group (e.g., the environmental IoT device can trigger a switch, and the network node can assign a new group based on the trigger), and in other cases, the trigger can be an indication that the environmental IoT device has switched groups (and can trigger the network node to switch the group assigned to the environmental IoT device by the network node to the group that the environmental IoT device has already switched to). Therefore, the network node can configure conditions for each group, and when the corresponding conditions are met, the environmental IoT device can directly use the new group. In this example, the environmental IoT device can indicate the new group to the network node via the trigger.

[0112] As an example of triggering, when the energy state of an environmental IoT device is greater than a threshold, the environmental IoT device may trigger a group switch (e.g., the environmental IoT device may trigger a switch from the group corresponding to device type "Device 1" to the group corresponding to device type "Device 2a", or it may switch to a new group configured with a longer activity time than the current group of the environmental IoT device). As another example, when the energy state of an environmental IoT device is lower than a threshold, the environmental IoT device may trigger a group switch, for example, to a new group configured with a shorter activity time.

[0113] As shown in the figure, a network node can send, and an environmental IoT device can receive, an instruction 530 regarding the environmental IoT device being assigned to a second group. In the case where the environmental IoT device autonomously switches groups, for example, based on the configuration information described above, the instruction 530 may be or include the configuration information shown at reference numeral 510. Regarding... Figure 6 An example of the structure of Indicator 530 is provided. Indicator 530 can be sent via broadcast signaling, multicast signaling, or unicast signaling. Additionally or alternatively, Indicator 530 can be sent via physical layer messages or MAC layer messages.

[0114] In some aspects, indication 530 can be a sequence-based indication. For example, indication 530 may include signals generated using a sequence. In some aspects, indication 530 may be transmitted via broadcast signaling. In this example, a single sequence may indicate to all environmental IoT devices that receive indication 530 that they are switching to a group mapped to that single sequence. As mentioned above, the mapping between sequences and groups may be defined by configuration information or in the wireless communication specification.

[0115] In some aspects, indication 530 can be sent via multicast or unicast signaling. In some aspects, different first groups or environmental IoT devices (from which environmental IoT devices are switching to a second group) can utilize different sequence configurations such that a given sequence can indicate a first group or environmental IoT device to switch to the second group associated with that given sequence. For example, in some aspects, the first group and the second group (e.g., a pair of groups) can share the same sequence. As another example, the sequence can be mapped to: (1) a second group or an indication to switch groups; and (2) a duration after which the environmental IoT device or group should switch back to the original group (e.g., the first group). As another example, a first switching direction (e.g., from the first group to the second group) can be mapped to a first sequence, and a second switching direction (in this example, from the second group to the first group) can be mapped to a second sequence.

[0116] In some respects, network nodes can use Instruction 530 to trigger group switching for ambient IoT devices. For example, a network node can assign a new group identifier to an ambient IoT device. As a first example, the ambient IoT device may be in a first group configured to select resources during inventory operations based on downlink signal strength measurements, and the network node can instruct the ambient IoT device to switch groups based on whether the ambient IoT device's amplification power meets a threshold. As a second example, a network node can trigger group switching for the ambient IoT device when service priority or latency requirements are higher or lower than a threshold.

[0117] In some aspects, there may be no restrictions on when an indication can be sent. For example, a network node or environmental IoT device may be allowed to switch groups at any time (e.g., to indicate a new group). In other aspects, there may be one or more restrictions on when a network node or environmental IoT device can switch an environmental IoT device to a new group. For example, these restrictions may be defined by the configuration information described above (e.g., any combination of the restrictions described above). As another example, one or more restrictions described above regarding the configuration information (e.g., any combination of the restrictions described above) may be specified in the wireless communication specification.

[0118] As indicated by reference numeral 540, an environmental IoT device may communicate according to this instruction. For example, an environmental IoT device may perform one or more communications based on being assigned to a second group. As an example, an environmental IoT device may send or receive communications associated with an inventory operation. An inventory operation may include network node identification of a set of environmental IoT devices and / or parameters associated with that set of environmental IoT devices. For example, a network node may trigger a group of environmental IoT devices to send communications, such as initial access communications. This is further elaborated below. Figure 7 To describe in more detail.

[0119] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0120] Figure 6 This is a diagram illustrating example 600 of an instruction for a new group of environmental IoT devices according to this disclosure. Example 600 relates to groups X, Y, and Z and environmental IoT devices 1 and 2 (e.g., UE 120, regarding...). Figure 4 and Figure 5 The described environment (IoT devices).

[0121] As shown in the figure, environmental IoT devices 1 and 2 may initially belong to group X (e.g., based on a first dynamic indication or static or semi-static configuration). As shown in the figure, network nodes (e.g., network node 110, UE 120, ...) Figure 5The network node can provide a first instruction 530. As shown, the first instruction 530 can cause environmental IoT devices 1 and 2 to switch from group X to group Y. For example, the first instruction 530 can identify group X (such as using an identifier or index of group X or a sequence mapped to group X) and can instruct environmental IoT devices belonging to group X to switch to group Y. As another example, the first instruction 530 can identify environmental IoT devices 1 and 2 and can instruct environmental IoT devices 1 and 2 to switch to group Y. Therefore, environmental IoT devices 1 and 2 can switch from group X to group Y according to the first instruction 530.

[0122] As shown in the figure, environmental IoT device 1 and / or environmental IoT device 2 can receive a second instruction 530. In some aspects, the second instruction 530 can be unicast to environmental IoT device 1. In some aspects, the second instruction 530 can be multicast to environmental IoT device 1 (and one or more other environmental IoT devices, which may include, for example, environmental IoT device 2). In some aspects, the second instruction 530 can be broadcast. As shown in the figure, environmental IoT device 1 can switch to group Z according to the second instruction 530. For example, the second instruction 530 can identify environmental IoT device 1 and can indicate group Z. Therefore, environmental IoT device 1 can switch to group Z according to the second instruction 530.

[0123] Example indication 530 (such as first indication 530 or second indication 530) is shown by reference numeral 610. Example indication 530 uses a payload to indicate a second group. In other examples described herein, a sequence may indicate a second group. As shown by reference numeral 620, indication 530 may include a device identifier and / or an identifier of the first group. The device identifier may, for example, use an identifier of one or more environmental IoT devices to identify or indicate one or more environmental IoT devices. For example, the device identifier may be a unique identifier (such as an Evolution Group Core identifier, a contention-resolved identifier, or a truncated version of the above identifiers). As another example, the device identifier may be a local identifier such as one within the group to which the environmental IoT device belongs.

[0124] The identifier of the first group can identify the group of the environmental IoT device, so that the environmental IoT device can switch to the group indicated by the second group indicated by the reference numeral 630.

[0125] The second set of indications may indicate the group to which an environmental IoT device or group of environmental IoT devices is to switch. As shown by reference numeral 640, in some aspects, the second set of indications may include a bitmap or set of bits. For example, indication 530 may include a bit or bitmap indication for indicating a new group and a device or group identifier (shown by reference numeral 620) for indicating which environmental IoT devices or groups are to switch to the new group. In some aspects, each environmental IoT device may support only two groups. In this example, the bitmap or set of bits may include a single bit. As another example, the second set of indications may include a bit or bitmap indication for indicating a new group and an indication of duration. Duration may indicate the length of time the device or device group indicated by the device or group identifier shown by reference numeral 620 is to be assigned to the group indicated by the bit or bitmap indication. As another example, as shown by reference numeral 650, in some aspects, the second set of indications may include a new group identifier (such as a set of bits or values ​​that explicitly identify the new group). In some examples, the first set of identifiers (shown by reference numeral 620) may indicate multiple groups, or the second set of indications may indicate multiple groups. Therefore, a single indication 530 can support multiple groups changed via a single group. In some aspects, the new group identifier can be full-length (e.g., as defined by a wireless communication specification or configuration information). In other aspects, the new group identifier can be a truncated identifier (e.g., one or more values ​​or bits can be discarded from the new group identifier). As another example, as shown by reference numeral 660, in some aspects, the second group indication can include a group index. The group index can identify a group from a set of groups based on the group's index (e.g., 0, 1, 2, 3, etc.).

[0126] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0127] Figure 7 This is a diagram illustrating example 700 of a group handover performed in conjunction with initial access according to this disclosure. Example 700 includes an environmental IoT device (e.g., UE 120, regarding...). Figure 4 , Figure 5 and Figure 6 The described environment (IoT devices) and network nodes (e.g., network node 110, UE 120, etc.) Figure 4 , Figure 5 and Figure 6 (The described reader or other network node). In Example 700, the network node may assign a group identifier after initial access.

[0128] As shown by reference numeral 710, a network node may select a group of environmental IoT devices (e.g., a designated group) for initial access. In some aspects, initial access may be an inventory operation or part of an inventory operation. For example, a network node may identify a group of environmental IoT devices to be triggered for initial access (such as a designated group of environmental IoT devices). In some aspects, a group of environmental IoT devices may include all devices within the scope of the network node. In some aspects, a group of environmental IoT devices may include all devices with a specific device type (as described above). As shown by reference numeral 720, a network node may optionally trigger initial access for the selected group of environmental IoT devices, which may reduce conflicts among environmental IoT devices.

[0129] As indicated by reference numeral 730, the environmental IoT device may send signals related to inventory operations or initial access. For example, the environmental IoT device may send an indication of a request for inventory operations or initial access. As indicated by reference numeral 740, network nodes and the environmental IoT device may perform contention resolution. For example, network nodes and the environmental IoT device may resolve conflicts associated with the transmission of signals indicated by reference numeral 730.

[0130] In some respects, a subset of environmental IoT devices (e.g., a true subset) can successfully access the network node after contention resolution (e.g., after conflict resolution). The network node can assign one or more groups to the environmental IoT devices, such as subsets of environmental IoT devices that have successfully accessed the network node, as indicated by reference numeral 750. For example, the network node can send an indication 530 for a subset of environmental IoT devices. Thus, the network node can assign group identifiers to environmental IoT devices that have successfully accessed the network node, which can facilitate subsequent uplink or downlink communication. The assignment of these group identifiers can be done via RRC configuration, physical signals, or MAC signals (e.g., MAC-CE).

[0131] In some aspects, a network node may provide indication 530 (e.g., indicating a group identifier) ​​after identifying the environment IoT device. For example, a network node may always provide indication 530 after identifying the environment IoT device. In this example, in some cases, the indicated group (e.g., group identifier) ​​may be the same as the group to which the environment IoT belonged before initial access.

[0132] In some aspects, network nodes may provide indications 530 only for environmental IoT devices that are switching groups. For example, a network node may only indicate a group identifier that is different from the group identifier of the environmental IoT device from its initial access. In some aspects, network nodes may provide information indicating that the environmental IoT device remains assigned to the previous group. For example, one or more bits may indicate that the environmental IoT device will reuse the previous group identifier.

[0133] In some aspects, the environmental IoT device and network node may perform a second inventory operation or initial access, as indicated by reference numeral 760. In some aspects, the environmental IoT device may continue to use the group indicated by the network node at reference numeral 750 for the second inventory operation or initial access. In some other aspects, the environmental IoT device may switch back to the first group to which it was assigned before the first initial access for the second inventory operation or initial access.

[0134] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.
