[0035] Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable mediums for arranging devices into groups and allocating resources (e.g., time, frequency, spatial, coding scheme, and / or the like, such as corresponding to access occasions) to the groups of devices. In particular, certain aspects provide techniques for a grouping device (e.g., a network entity; a user equipment (UE) ; a reader device, such as a network entity or UE, configured to read another device, such as a tag; an apparatus; etc. ) to: group devices together for communications (e.g., with the grouping device, such as directly or indirectly via one or more other devices; with another device; etc. ) , allocate resources to the groups of devices, adjust the groups dynamically, select subgroups for resource allocations, and / or allocate an amount of resources to each device in each group of devices. In some aspects, the devices that are grouped by the grouping device for the resource allocations may be ambient Internet of Things (A-IoT) devices, but it is to be understood that the techniques described herein are not limited to A-IoT devices, though some techniques may be described with respect to A-IoT devices as an example.
[0036] A-IoT devices typically have low complexity designs configured to use low power for communicating (e.g., transmitting and / or receiving) wireless signals. For example, A-IoT devices may generally have limited energy storage capabilities, such as limited storage batteries or a capacitor or other short term energy storage device. In some cases, A-IoT devices rely on energy harvesting from one or more external sources. The one or more external sources may include: solar energy, thermal energy, kinetic energy, radio frequency (RF) energy, electromagnetic radiation (EMR) , other types of ambient energy, and the like. For example, an A-IoT device may include one or more components that allow the A-IoT device to harvest energy, such as solar cells, RF power converters, and the like. Example A-IoT devices include tags, such as radio frequency identification (RFID) tags, passive user equipments (UEs) , backscattering UEs, and the like.
[0037] An A-IoT device may not include active RF components, and instead may use passive radio equipment (e.g., a backscatter-type radio) for communicating. For example, A-IoT devices are generally capable of asynchronous communication and may not have a power amplifier or a low-noise amplifier. A-IoT UEs may generally utilize a light protocol stack.
[0038] In certain aspects, an A-IoT device, using passive radio equipment, is configured to modulate and reflect incident RF signals (e.g., a carrier wave (CW) ) . For example, another device (e.g., a UE, a network entity, relay device, etc. ) may transmit a CW in the direction of the A-IoT device. The A-IoT device, using the passive radio equipment, modulates and reflects the CW to communicate data. The modulated and reflected CW may be referred to as a backscattered signal, where information is encoded in the backscattered signal based on the modulation.
[0039] In some cases, it may be beneficial and / or efficient to group multiple (e.g., A-IoT) devices together, such as when the devices are successfully accessed by a device (e.g., a reader device, a network entity, a UE, etc. ) . For example, grouping the devices together may support more efficient communications between the multiple devices and another device by configuring resources for the group rather than for individual devices.
[0040] One or more technical problems arise when grouping the devices and allocating resources to the groups, such as how a grouping device should group the devices. For example, devices in a same group may have different amounts of data to communicate (e.g., transmit, such as to the grouping device, indirectly or directly, or to another device) . As such, resources allocated to the group to facilitate communications for the devices in the group may be insufficient and / or overprovisioned for one or more devices in the group based on the respective amounts of data the devices have to communicate.
[0041] Accordingly, the techniques and signaling described herein may provide a technical solution for arranging devices into groups based on one or more factors and allocating resources to the groups of devices. For example, the technical solution may include a grouping device configured to group devices into respective groups based on which devices have similar (e.g., within a threshold range, such as an upper bound and lower bound) amounts of data for communication, such as similar amount of data for communication in memory / buffered (e.g., data to be transmitted by the devices) , and / or based on additional factors (e.g., pathloss between the device and another device to which the data is to be communicated, distance between the device and another device to which the data is to be communicated, energy state of the device (e.g., remaining battery) , error rates of the device (e.g., bit error rate (BER) , block error rate (BLER) such as for communications with another device to which the data is to be communicated, a number of contiguous failed decodings of signals by the device such as signal from another device to which the data is to be communicated, acknowledgment (ACK) feedback (e.g., ACK or negative ACK (NACK) ) for a previous communication by the device such as from another device to which the data is to be communicated, channel condition (s) (e.g., received signal strength indicator (RSSI) , reference signal received power (RSRP) , reference signal received quality (RSRQ) , etc. ) between the device and another device to which the data is to be communicated, etc. ) . For example, multiple threshold ranges of amount of data to be communicated may be defined, such as to divide the devices into groups, such that each threshold range is associated with a group. A device may be assigned to a group where the amount of data to communicate at the device is within the threshold range associated with the group.
[0042] In certain aspects, assigning devices with a similar amount of data to communicate to a same group allows resources to be more evenly allocated between the devices as the devices may more evenly utilize resources for communication. Accordingly, in some cases, resources may be defined for the group generally, and implicitly allocated (e.g., evenly) among the devices in the group, such as without having to individually assign resources to each device in the group, which may reduce overhead. Other factors listed herein for grouping devices may also similarly affect a number of resources used by a device for communication of data, such that they may similarly be taken into account.
[0043] Additionally or alternatively, the technical solution may include the grouping device dynamically managing the groups of devices by indicating which devices are not included in a group anymore, which devices are to stay in a group, which devices are to be added to a group, or a combination thereof. For example, an amount of data a device has to communicate, or other factors for a device, may change, such that the device may be better fit to another group. Dynamic management of groups may provide the benefit of being able to revise groupings to deal with changing conditions.
[0044] Additionally or alternatively, the technical solution may include the grouping device selecting subgroups of devices in a group for resource allocations. For example, the reader device may indicate: whether a message is addressed to the full group or to a subgroup of the group, a size of the subgroup, a group common identifier, one or more identifiers of individual devices to include or not include in the subgroup, or any combination thereof. For example, as discussed changing a group of a device may be beneficial. However, in some cases, the change may only need to be temporary. Accordingly, instead of using signaling to change a group of a device back and forth, a subgroup may be defined for a group, which may allow dynamic changes to the group with reduced signaling overhead.
[0045] Additionally or alternatively, the technical solution may include the grouping device allocating a same amount of resources to each device in a same group. For example, the reader device may allocate the resources to each device in a group based on a largest amount of data pending among the devices of the group and / or may indicate a same allocation of resources to the group for multiple time periods until all devices in the group have no data pending for communications. Such allocation may utilize reduced signaling overhead, such as by not having to individually indicate a respective amount of resources allocated to each device.
[0046] The techniques for arranging devices into groups and allocating resources to the groups of devices as described herein may provide any of various beneficial effects and / or advantages. For example, grouping the devices based on the one or more factors described herein (e.g., amounts of data pending for communication, additional indications, etc. ) may enable more efficient communications between the devices and a device based on allocating resources specifically to the groups (e.g., to mitigate possible insufficient and / or overprovisioned resource allocations) . Additionally or alternatively, dynamically managing the groups and / or selecting subgroups of devices from the groups may further enable more efficient communications between the devices and a device by allocating resources as needed to specific devices in the groups for those specific devices to complete respective communications with the device after the other devices in the group have finished their communications. Additionally or alternatively, allocating a same amount of resources to each device in a same group may decrease signaling complexity for communications between the devices and another device.
[0047] Introduction to Wireless Communications Networks
[0048] The techniques and methods described herein may be used for various wireless communications networks. While aspects may be described herein using terminology commonly associated with 3G, 4G, 5G, 6G, and / or other generations of wireless technologies, aspects of the present disclosure may likewise be applicable to other communications systems and standards not explicitly mentioned herein.
[0049] FIG. 1 depicts an example of a wireless communications network 100, in which aspects described herein may be implemented.
[0050] Generally, wireless communications network 100 includes various network entities (alternatively, network elements or network nodes) . A network entity is generally a communications device and / or a communications function performed by a communications device (e.g., a user equipment (UE) , a base station (BS) , a component of a BS, a server, etc. ) . As such communications devices are part of wireless communications network 100, and facilitate wireless communications, such communications devices may be referred to as wireless communications devices. For example, various functions of a network as well as various devices associated with and interacting with a network may be considered network entities. Further, wireless communications network 100 includes terrestrial aspects (also referred to herein as non-terrestrial network entities) , such as ground-based network entities (e.g., BSs 102) , and non-terrestrial aspects, such as satellite 140 and / or aerial or spaceborne platform (s) , which may include network entities on-board (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and UEs.
[0051] In the depicted example, wireless communications network 100 includes BSs 102, UEs 104, and one or more core networks, such as an Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190, which interoperate to provide communications services over various communications links, including wired and wireless links.
[0052] FIG. 1 depicts various example UEs 104, which may more generally include: a cellular phone, smart phone, session initiation protocol (SIP) phone, laptop, personal digital assistant (PDA) , satellite radio, global positioning system, multimedia device, video device, digital audio player, camera, game console, tablet, smart device, wearable device, vehicle, electric meter, gas pump, large or small kitchen appliance, healthcare device, implant, sensor / actuator, display, internet of things (IoT) devices, always on (AON) devices, edge processing devices, data centers, or other similar devices. UEs 104 may also be referred to more generally as a mobile device, a wireless device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.
[0053] BSs 102 wirelessly communicate with (e.g., transmit signals to or receive signals from) UEs 104 via communications links 120. The communications links 120 between BSs 102 and UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a BS 102 and / or downlink (DL) (also referred to as forward link) transmissions from a BS 102 to a UE 104. The communications links 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity in various aspects.
[0054] BSs 102 may generally include: a NodeB, enhanced NodeB (eNB) , next generation enhanced NodeB (ng-eNB) , next generation NodeB (gNB or gNodeB) , access point, base transceiver station, radio base station, radio transceiver, transceiver function, transmission reception point, and / or others. Each of BSs 102 may provide communications coverage for a respective coverage area 110, which may sometimes be referred to as a cell, and which may overlap in some cases (e.g., small cell 102’ may have a coverage area 110’ that overlaps the coverage area 110 of a macro cell) . A BS may, for example, provide communications coverage for a macro cell (covering relatively large geographic area) , a pico cell (covering relatively smaller geographic area, such as a sports stadium) , a femto cell (relatively smaller geographic area (e.g., a home) ) , and / or other types of cells.
[0055] Generally, a cell may refer to a portion, partition, or segment of wireless communication coverage served by a network entity within a wireless communication network. A cell may have geographic characteristics, such as a geographic coverage area, as well as radio frequency characteristics, such as time and / or frequency resources dedicated to the cell. For example, a specific geographic coverage area may be covered by multiple cells employing different frequency resources (e.g., bandwidth parts) and / or different time resources. As another example, a specific geographic coverage area may be covered by a single cell. In some contexts (e.g., a carrier aggregation scenario and / or multi-connectivity scenario) , the terms “cell” or “serving cell” may refer to or correspond to a specific carrier frequency (e.g., a component carrier) used for wireless communications, and a “cell group” may refer to or correspond to multiple carriers used for wireless communications. As examples, in a carrier aggregation scenario, a UE may communicate on multiple component carriers corresponding to multiple (serving) cells in the same cell group, and in a multi-connectivity (e.g., dual connectivity) scenario, a UE may communicate on multiple component carriers corresponding to multiple cell groups.
[0056] While BSs 102 are depicted in various aspects as unitary communications devices, BSs 102 may be implemented in various configurations. For example, one or more components of a base station may be disaggregated, including a central unit (CU) , one or more distributed units (DUs) , one or more radio units (RUs) , a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) , or a Non-Real Time (Non-RT) RIC, to name a few examples. In another example, various aspects of a base station may be virtualized. More generally, a base station (e.g., BS 102) may include components that are located at a single physical location or components located at various physical locations. In examples in which a base station includes components that are located at various physical locations, the various components may each perform functions such that, collectively, the various components achieve functionality that is similar to a base station that is located at a single physical location. In some aspects, a base station including components that are located at various physical locations may be referred to as a disaggregated radio access network architecture, such as an Open RAN (O-RAN) or Virtualized RAN (VRAN) architecture. FIG. 2 depicts and describes an example disaggregated base station architecture.
[0057] Different BSs 102 within wireless communications network 100 may also be configured to support different radio access technologies, such as 3G, 4G, and / or 5G. For example, BSs 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) ) may interface with the EPC 160 through first backhaul links 132 (e.g., an S1 interface) . BSs 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN) ) may interface with 5GC 190 through second backhaul links 184. BSs 102 may communicate directly or indirectly (e.g., through the EPC 160 or 5GC 190) with each other over third backhaul links 134 (e.g., X2 interface) , which may be wired or wireless.
[0058] Wireless communications network 100 may subdivide the electromagnetic spectrum into various classes, bands, channels, or other features. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, or a subband. For example, 3GPP currently defines Frequency Range 1 (FR1) as including 410 MHz –7125 MHz, which is often referred to (interchangeably) as “Sub-6 GHz” . Similarly, 3GPP currently defines Frequency Range 2 (FR2) as including 24,250 MHz –71,000 MHz, which is sometimes referred to (interchangeably) as a “millimeter wave” ( “mmW” or “mmWave” ) . In some cases, FR2 may be further defined in terms of sub-ranges, such as a first sub-range FR2-1 including 24,250 MHz –52,600 MHz and a second sub-range FR2-2 including 52,600 MHz –71,000 MHz. A base station configured to communicate using mmWave / near mmWave radio frequency bands (e.g., a mmWave base station such as BS 180) may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.
[0059] The communications links 120 between BSs 102 and, for example, UEs 104, may be through one or more carriers, which may have different bandwidths (e.g., 5, 10, 15, 20, 100, 400, and / or other MHz) , and which may be aggregated in various aspects. Carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) .
[0060] Communications using higher frequency bands may have higher path loss and a shorter range compared to lower frequency communications. Accordingly, certain base stations (e.g., 180 in FIG. 1) may utilize beamforming 182 with a UE 104 to improve path loss and range. For example, BS 180 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and / or antenna arrays to facilitate the beamforming. In some cases, BS 180 may transmit a beamformed signal to UE 104 in one or more transmit directions 182’. UE 104 may receive the beamformed signal from the BS 180 in one or more receive directions 182”. UE 104 may also transmit a beamformed signal to the BS 180 in one or more transmit directions 182”. BS 180 may also receive the beamformed signal from UE 104 in one or more receive directions 182’. BS 180 and UE 104 may then perform beam training to determine the best receive and transmit directions for each of BS 180 and UE 104. Notably, the transmit and receive directions for BS 180 may or may not be the same. Similarly, the transmit and receive directions for UE 104 may or may not be the same.
[0061] Wireless communications network 100 further includes a Wi-Fi AP 150 in communication with Wi-Fi stations (STAs) 152 via communications links 154 in, for example, a 2.4 GHz and / or 5 GHz unlicensed frequency spectrum.
[0062] Certain UEs 104 may communicate with each other using device-to-device (D2D) communications link 158. D2D communications link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH) , a physical sidelink discovery channel (PSDCH) , a physical sidelink shared channel (PSSCH) , a physical sidelink control channel (PSCCH) , and / or a physical sidelink feedback channel (PSFCH) .
[0063] EPC 160 may include various functional components, including: a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and / or a Packet Data Network (PDN) Gateway 172, such as in the depicted example. MME 162 may be in communication with a Home Subscriber Server (HSS) 174. MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, MME 162 provides bearer and connection management.
[0064] Generally, user Internet protocol (IP) packets are transferred through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation as well as other functions. PDN Gateway 172 and the BM-SC 170 are connected to IP Services 176, which may include, for example, the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a Packet Switched (PS) streaming service, and / or other IP services.
[0065] BM-SC 170 may provide functions for MBMS user service provisioning and delivery. BM-SC 170 may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN) , and / or may be used to schedule MBMS transmissions. MBMS Gateway 168 may be used to distribute MBMS traffic to the BSs 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.
[0066] 5GC 190 may include various functional components, including: an Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. AMF 192 may be in communication with Unified Data Management (UDM) 196.
[0067] AMF 192 is a control node that processes signaling between UEs 104 and 5GC 190. AMF 192 provides, for example, quality of service (QoS) flow and session management.
[0068] Internet protocol (IP) packets are transferred through UPF 195, which is connected to the IP Services 197, and which provides UE IP address allocation as well as other functions for 5GC 190. IP Services 197 may include, for example, the Internet, an intranet, an IMS, a PS streaming service, and / or other IP services.
[0069] In various aspects, a network entity or network node can be implemented as an aggregated base station, as a disaggregated base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.
[0070] FIG. 2 depicts an example disaggregated base station 200 architecture. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that can communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more disaggregated base station units (such as a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC) 225 via an E2 link, or a Non-Real Time (Non-RT) RIC 215 associated with a Service Management and Orchestration (SMO) Framework 205, or both) . A CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DUs 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RUs 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 240.
[0071] Each of the units, e.g., the CUs 210, the DUs 230, the RUs 240, as well as the Near-RT RICs 225, the Non-RT RICs 215 and the SMO Framework 205, may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communications interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally or alternatively, the units can include a wireless interface, which may include a receiver, a transmitter or transceiver (such as a radio frequency (RF) transceiver) , configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.
[0072] In some aspects, the CU 210 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) , packet data convergence protocol (PDCP) , service data adaptation protocol (SDAP) , or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 210. The CU 210 may be configured to handle user plane functionality (e.g., Central Unit –User Plane (CU-UP) ) , control plane functionality (e.g., Central Unit –Control Plane (CU-CP) ) , or a combination thereof. In some implementations, the CU 210 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 210 can be implemented to communicate with the DU 230, as necessary, for network control and signaling.
[0073] The DU 230 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 240. In some aspects, the DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3rd Generation Partnership Project (3GPP) . In some aspects, the DU 230 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 230, or with the control functions hosted by the CU 210.
[0074] Lower-layer functionality can be implemented by one or more RUs 240. In some deployments, an RU 240, controlled by a DU 230, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT) , inverse FFT (iFFT) , digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like) , or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU (s) 240 can be implemented to handle over the air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communications with the RU (s) 240 can be controlled by the corresponding DU 230. In some scenarios, this configuration can enable the DU (s) 230 and the CU 210 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0075] The SMO Framework 205 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements which may be managed via an operations and maintenance interface (such as an O1 interface) . For virtualized network elements, the SMO Framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface) . Such virtualized network elements can include, but are not limited to, CUs 210, DUs 230, RUs 240 and Near-RT RICs 225. In some implementations, the SMO Framework 205 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 211, via an O1 interface. Additionally, in some implementations, the SMO Framework 205 can communicate directly with one or more DUs 230 and / or one or more RUs 240 via an O1 interface. The SMO Framework 205 also may include a Non-RT RIC 215 configured to support functionality of the SMO Framework 205.
[0076] The Non-RT RIC 215 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence / Machine Learning (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the Near-RT RIC 225. The Non-RT RIC 215 may be coupled to or communicate with (such as via an A1 interface) the Near-RT RIC 225. The Near-RT RIC 225 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 210, one or more DUs 230, or both, as well as an O-eNB, with the Near-RT RIC 225.
[0077] In some implementations, to generate AI / ML models to be deployed in the Near-RT RIC 225, the Non-RT RIC 215 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 225 and may be received at the SMO Framework 205 or the Non-RT RIC 215 from non-network data sources or from network functions. In some examples, the Non-RT RIC 215 or the Near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 215 may monitor long-term trends and patterns for performance and employ AI / ML models to perform corrective actions through the SMO Framework 205 (such as reconfiguration via O1) or via creation of RAN management policies (such as A1 policies) .
[0078] FIG. 3 depicts aspects of an example BS 102 and a UE 104.
[0079] Generally, BS 102 includes various processors (e.g., 318, 320, 330, 338, and 340) , antennas 334a-t (collectively 334) , transceivers 332a-t (collectively 332) , which include modulators and demodulators, and other aspects, which enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 314) . For example, BS 102 may send and receive data between BS 102 and UE 104. BS 102 includes controller / processor 340, which may be configured to implement various functions described herein related to wireless communications. Note that the BS 102 may have a disaggregated architecture as described herein with respect to FIG. 2.
[0080] Generally, UE 104 includes various processors (e.g., 358, 364, 366, 370, and 380) , antennas 352a-r (collectively 352) , transceivers 354a-r (collectively 354) , which include modulators and demodulators, and other aspects, which enable wireless transmission of data (e.g., retrieved from data source 362) and wireless reception of data (e.g., provided to data sink 360) . UE 104 includes controller / processor 380, which may be configured to implement various functions described herein related to wireless communications.
[0081] In regards to an example downlink transmission, BS 102 includes a transmit processor 320 that may receive data from a data source 312 and control information from a controller / processor 340. The control information may be for the physical broadcast channel (PBCH) , physical control format indicator channel (PCFICH) , physical hybrid automatic repeat request (HARQ) indicator channel (PHICH) , physical downlink control channel (PDCCH) , group common PDCCH (GC PDCCH) , and / or others. The data may be for the physical downlink shared channel (PDSCH) , in some examples.
[0082] Transmit processor 320 may process (e.g., encode and symbol map) the data and control information to obtain data symbols and control symbols, respectively. Transmit processor 320 may also generate reference symbols, such as for the primary synchronization signal (PSS) , secondary synchronization signal (SSS) , PBCH demodulation reference signal (DMRS) , and channel state information reference signal (CSI-RS) .
[0083] Transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, and / or the reference symbols, if applicable, and may provide output symbol streams to the modulators (MODs) in transceivers 332a-332t. Each modulator in transceivers 332a- 332t may process a respective output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. Downlink signals from the modulators in transceivers 332a-332t may be transmitted via the antennas 334a-334t, respectively.
[0084] In order to receive the downlink transmission, UE 104 includes antennas 352a-352r that may receive the downlink signals from the BS 102 and may provide received signals to the demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator may further process the input samples to obtain received symbols.
[0085] RX MIMO detector 356 may obtain received symbols from all the demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. Receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.
[0086] In regards to an example uplink transmission, UE 104 further includes a transmit processor 364 that may receive and process data (e.g., for the PUSCH) from a data source 362 and control information (e.g., for the physical uplink control channel (PUCCH) ) from the controller / processor 380. Transmit processor 364 may also generate reference symbols for a reference signal (e.g., for the sounding reference signal (SRS) ) . The symbols from the transmit processor 364 may be precoded by a TX MIMO processor 366 if applicable, further processed by the modulators in transceivers 354a-354r (e.g., for SC-FDM) , and transmitted to BS 102.
[0087] At BS 102, the uplink signals from UE 104 may be received by antennas 334a-t, processed by the demodulators in transceivers 332a-332t, detected by a RX MIMO detector 336 if applicable, and further processed by a receive processor 338 to obtain decoded data and control information sent by UE 104. Receive processor 338 may provide the decoded data to a data sink 314 and the decoded control information to the controller / processor 340.
[0088] Memories 342 and 382 may store data and program codes for BS 102 and UE 104, respectively.
[0089] Scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.
[0090] In various aspects, BS 102 may be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” may refer to various mechanisms of outputting data, such as outputting data from data source 312, scheduler 344, memory 342, transmit processor 320, controller / processor 340, TX MIMO processor 330, transceivers 332a-t, antenna 334a-t, and / or other aspects described herein. Similarly, “receiving” may refer to various mechanisms of obtaining data, such as obtaining data from antennas 334a-t, transceivers 332a-t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.
[0091] In various aspects, UE 104 may likewise be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” may refer to various mechanisms of outputting data, such as outputting data from data source 362, memory 382, transmit processor 364, controller / processor 380, TX MIMO processor 366, transceivers 354a-t, antenna 352a-t, and / or other aspects described herein. Similarly, “receiving” may refer to various mechanisms of obtaining data, such as obtaining data from antennas 352a-t, transceivers 354a-t, RX MIMO detector 356, controller / processor 380, receive processor 358, memory 382, and / or other aspects described herein.
[0092] In some aspects, a processor may be configured to perform various operations, such as those associated with the methods described herein, and transmit (output) to or receive (obtain) data from another interface that is configured to transmit or receive, respectively, the data.
[0093] In various aspects, artificial intelligence (AI) processors 318 and 370 may perform AI processing for BS 102 and / or UE 104, respectively. The AI processor 318 may include AI accelerator hardware or circuitry such as one or more neural processing units (NPUs) , one or more neural network processors, one or more tensor processors, one or more deep learning processors, etc. The AI processor 370 may likewise include AI accelerator hardware or circuitry. As an example, the AI processor 370 may perform AI- based beam management, AI-based channel state feedback (CSF) , AI-based antenna tuning, and / or AI-based positioning (e.g., non-line of sight positioning prediction) . In some cases, the AI processor 318 may process feedback from the UE 104 (e.g., CSF) using hardware accelerated AI inferences and / or AI training. The AI processor 318 may decode compressed CSF from the UE 104, for example, using a hardware accelerated AI inference associated with the CSF. In certain cases, the AI processor 318 may perform certain RAN-based functions including, for example, network planning, network performance management, energy-efficient network operations, etc.
[0094] FIGS. 4A, 4B, 4C, and 4D depict aspects of data structures for a wireless communications network, such as wireless communications network 100 of FIG. 1.
[0095] In particular, FIG. 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, FIG. 4B is a diagram 430 illustrating an example of DL channels within a 5G subframe, FIG. 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and FIG. 4D is a diagram 480 illustrating an example of UL channels within a 5G subframe.
[0096] Wireless communications systems may utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on the uplink and downlink. Such systems may also support half-duplex operation using time division duplexing (TDD) . OFDM and single-carrier frequency division multiplexing (SC-FDM) partition the system bandwidth (e.g., as depicted in FIGS. 4B and 4D) into multiple orthogonal subcarriers. Each subcarrier may be modulated with data. Modulation symbols may be sent in the frequency domain with OFDM and / or in the time domain with SC-FDM.
[0097] A wireless communications frame structure may be frequency division duplex (FDD) , in which, for a particular set of subcarriers, subframes within the set of subcarriers are dedicated for either DL or UL. Wireless communications frame structures may also be time division duplex (TDD) , in which, for a particular set of subcarriers, subframes within the set of subcarriers are dedicated for both DL and UL.
[0098] In FIG. 4A and 4C, the wireless communications frame structure is TDD where D is DL, U is UL, and X is flexible for use between DL / UL. UEs may be configured with a slot format through a received slot format indicator (SFI) (dynamically through DL control information (DCI) , or semi-statically / statically through radio resource control (RRC) signaling) . In the depicted examples, a 10 ms frame is divided into 10 equally sized 1 ms subframes. Each subframe may include one or more time slots. In some examples, each slot may include 12 or 14 symbols, depending on the cyclic prefix (CP) type (e.g., 12 symbols per slot for an extended CP or 14 symbols per slot for a normal CP) . Subframes may also include mini-slots, which generally have fewer symbols than an entire slot. Other wireless communications technologies may have a different frame structure and / or different channels.
[0099] In certain aspects, the number of slots within a subframe (e.g., a slot duration in a subframe) is based on a numerology, which may define a frequency domain subcarrier spacing and symbol duration as further described herein. In certain aspects, given a numerology μ, there are 2μ slots per subframe. Thus, numerologies (μ) 0 to 6 may allow for 1, 2, 4, 8, 16, 32, and 64 slots, respectively, per subframe. In some cases, the extended CP (e.g., 12 symbols per slot) may be used with a specific numerology, e.g., numerology 2 allowing for 4 slots per subframe. The subcarrier spacing and symbol length / duration are a function of the numerology. The subcarrier spacing may be equal to 2μ×15 kHz, where μ is the numerology 0 to 6. As an example, the numerology μ=0 corresponds to a subcarrier spacing of 15 kHz, and the numerology μ=6 corresponds to a subcarrier spacing of 960 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIGS. 4A, 4B, 4C, and 4D provide an example of a slot format having 14 symbols per slot (e.g., a normal CP) and a numerology μ=2 with 4 slots per subframe. In such a case, the slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.
[0100] As depicted in FIGS. 4A, 4B, 4C, and 4D, a resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs) ) that extends, for example, 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs) . The number of bits carried by each RE depends on the modulation scheme including, for example, quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM) .
[0101] As illustrated in FIG. 4A, some of the REs carry reference (pilot) signals (RS) for a UE (e.g., UE 104 of FIGS. 1 and 3) . The RS may include demodulation RS (DMRS) and / or channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS) , beam refinement RS (BRRS) , and / or phase tracking RS (PT-RS) .
[0102] FIG. 4B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) , each CCE including, for example, nine RE groups (REGs) , each REG including, for example, four consecutive REs in an OFDM symbol.
[0103] A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE (e.g., 104 of FIGS. 1 and 3) to determine subframe / symbol timing and a physical layer identity.
[0104] A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing.
[0105] Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI) . Based on the PCI, the UE can determine the locations of the aforementioned DMRS. The physical broadcast channel (PBCH) , which carries a master information block (MIB) , may be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (SSB) , and in some cases, referred to as a synchronization signal block (SSB) . The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN) . The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs) , and / or paging messages.
[0106] As illustrated in FIG. 4C, some of the REs carry DMRS (indicated as R for one particular configuration, but other DMRS configurations are possible) for channel estimation at the base station. The UE may transmit DMRS for the PUCCH and DMRS for the PUSCH. The PUSCH DMRS may be transmitted, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. UE 104 may transmit sounding reference signals (SRS) . The SRS may be transmitted, for example, in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.
[0107] FIG. 4D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) , such as scheduling requests, a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a rank indicator (RI) , and HARQ ACK / NACK feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR) , a power headroom report (PHR) , and / or UCI.
[0108] Aspects Related to Arranging Devices into Groups and Allocating Resources to the Groups of Devices
[0109] FIGS. 5A, 5B, and 5C depict various example aspects of A-IoT communication systems. In some examples, the A-IoT communication systems may be an example of a wireless communications network 100 as described with reference to FIG. 1. Each of the A-IoT communication systems of FIGS. 5A, 5B, and 5C may depict communications between a reader device and a tag. In some examples, the reader device may represent a wireless communications device as described with reference to FIG. 1, such as a network entity, a base station, a UE, or the like. Additionally, the tag may be referred to as or include a wireless communications device, an A-IoT device, RFID tag, passive UEs, backscattering UEs, and the like.
[0110] In particular, FIG. 5A depicts an A-IoT communication system 500 with a reader device 504 communicating with a tag 506. In some examples, the reader device 504 may include and / or may be referred to as an RFID integrator, which can transmit and receive communications with the tag 506. Additionally, in some embodiments, an RFID system may generally include the reader device 504 and the tag 506. The tag 506 may include a simple structure and / or an envelope detector for receiving a CW from the reader device 504. For example, the reader device 504 may send a CW using an antenna 532 (e.g., similar to antenna 352a of FIG. 3) that is received by the tag 506 via a forward link (FL) 508 (e.g., a link from an RF source, such as the reader device 504 or more generally an FL transmitter, to the tag 506) . A CW is a waveform (e.g., sinusoidal waveform) that can be modulated with data (e.g., an information-bearing signal) to generate a modulated signal that conveys the data.
[0111] In some examples, the reader device 504 may send the CW based on sending an electromagnetic (EM) signal 512 that includes the CW and data (e.g., intended for the tag 506) . The FL CW may be used to power up the tag 506, provide the CW for the tag 506, or both. The FL data may include FL information, which can be commands, ACK / negative acknowledgment (NACK) feedback, etc.
[0112] Based on receiving the FL 508, the tag 506 may then modulate the CW (e.g., by varying the impedance coupled to an antenna of the tag 506, which may vary an amplitude and / or phase of the CW) to generate backscattered data (e.g., a modulated backscattered signal) . Subsequently, the tag 506 may transmit (e.g., reflect) the backscattered data via a backscatter link (BL) 510. For example, the tag 506 may transmit and / or reflect an EM signal 514 that includes the backscattered data back to the reader device 504 via the BL 510. Additionally or alternatively, the BL 510 may be referred to as a backward link. In some embodiments, the backscattered data may be referred to as or may include BL information, such as ACK / NACK feedback from the tag 506, data to be transmitted or backscattered by the tag 506, or other BL information. In some embodiments, the reader device 504 may be referred to as or may include a BL receiver. Additionally, the reader device 504 and RF source can be a same device (e.g., a monostatic device, which is described in greater detail with reference to FIGS. 6A and 6B) , which can generally be called a reader.
[0113] In FIG. 5B, an A-IoT communication system 501 is depicted. The A-IoT communications system 501 may include a reader device 504 and a tag 506. In the example of FIG. 5B, the reader device 504 may include or may be a network entity (e.g., gNB, base station, etc. ) . Accordingly, the FL 508 as described with reference to FIG. 5A for communications from the reader device 504 to the tag 506 may include or may be DL communications, and the BL 510 as described with reference to FIG. 5A for communications from the tag 506 to the reader device 504 may include or may be UL communications. In some embodiments, A-IoT may be referred to as Zero Power (ZP) -IoT, such as where the tag does not need to be self-powered and may harvest energy from the CW for operation.
[0114] In FIG. 5C, an A-IoT communication system 502 is depicted. The A-IoT communications system 502 may include a network entity 516 along with a reader device 504 and a tag 506. The network entity 516 may communicate with the reader device 504 via a Uu interface (e.g., UMTS air interface) . The reader device 504 and the tag 506 may communicate with each other using an FL and a BL (e.g., such as the FL 508 and the BL 510, respectively, as described with reference to FIG. 6A) . In some embodiments, the reader device 504 may include or may be a UE that serves as a relay for communications between the network entity 516 and the tag 506. In the example of FIG. 5C, the reader device 504 may be or may be referred to as a relaying device (e.g., similar to a sidelink (SL) relay) , but the interface between the reader device 504 and the tag 506 is not considered a sidelink.
[0115] In some embodiments, the tag 506 may be more powerful than a passive tag or device based on using energy harvesting and energy storage. In such embodiments, if the tag 506 can actively transmit signals (e.g., not only reflect modulated signals based on having more power) , the BL 510 may refer to a “backward link. ”
[0116] Table 1 provided below describes the different types of devices and / or tags that can exist in A-IoT.
[0117] Table 1 -Devices in A-IoT
[0118] FIGS. 6A, 6B, and 6C depict various example aspects of monostatic and bistatic A-IoT communication systems. For example, FIGS. 6A and 6B may depict examples of a monostatic A-IoT communication system 600 and a monostatic A-IoT communication system 601, respectively, and FIG. 6C may depict a bistatic A-IoT communication system 602. The monostatic and bistatic distinctions may refer to whether a reader device in each of the corresponding A-IoT communication systems is a same device or a different device than an RF source. For the monostatic A-IoT communication system 600 and the monostatic A-IoT communication system 601, the RF source and the reader device may be a same device (e.g., referred to generally as a “reader” ) . Additionally or alternatively, for the bistatic A-IoT communication system 602, the RF source and the reader device may be different devices.
[0119] In the monostatic A-IoT communication system 600 of FIG. 6A, a reader 604 may include an RF source 606 (e.g., transmitter) and a reader device 608 (e.g., receiver) . Additionally, the reader 604 may include an antenna 610 (e.g., for facilitating monostatic backscatter with a same antenna) . The reader 604 may send a signal 614 (e.g., transmitted signal) from the RF source 606 to a tag 612 via the antenna 610. For example, the signal 614 may be transmitted via a FL. The tag 612 may respond by sending a backscattered signal 616 to the reader device 608, which can be received by the reader 604 via the antenna 610. For example, the backscattered signal may transmitted via a BL. In some embodiments, an amount of signal 618 may be reflected from the antenna 610. Accordingly, the reader device 608 may receive the backscattered signal 616 based on taking the amount of signal 618 into account with the backscattered signal 616.
[0120] In the monostatic A-IoT communication system 601 of FIG. 6B, the reader 604 may also include the RF source 606 (e.g., transmitter) and the reader device 608 (e.g., receiver) , but may further include a first antenna 620 (e.g., a transmit antenna) for the RF source 606 and a second antenna 622 (e.g., a receive antenna) for the reader device 608 (e.g., for facilitating monostatic backscatter with separate antennas) . Accordingly, the reader 604 may send the signal 614 (e.g., transmitted signal) from the RF source 606 to the tag 612 via the first antenna 620 (e.g., via an FL) . The tag 612 may respond by sending the backscattered signal 616 to the reader device 608, which can be received via the second antenna 622 (e.g., via a BL) . In some embodiments, a signal leakage 624 may occur between the first antenna 620 and the second antenna 622. Accordingly, the reader device 608 may receive the backscattered signal 616 based on taking the signal leakage 624 into account with the backscattered signal 616
[0121] In the bistatic A-IoT communication system 602 of FIG. 6C, the RF source and the reader device may be different devices. For example, the RF source may include a network entity 626 (e.g., FL transmitter) , or other device, that can transmit modulated signals and unmodulated signals (e.g., a CW) , such as the signal 614. Additionally, the reader device may include a UE 628 (e.g., BL receiver) , or other device, that can receive the backscattered signal 618 from a tag 612. For example, the tag 612 may receive the modulated and unmodulated signals from the network entity 626 and may reflect and / or actively transmit modulated signals to the UE 628.
[0122] FIGS. 7A, 7B, 7C, 7D, and 7E depict various example aspects of allocating resources to groups of devices. In some examples, the example aspects of allocating resources to groups of devices may be used for grouping A-IoT devices (e.g., tags, RFID tags, passive UEs, backscattering UEs, etc. ) for communications with a device such as a network entity and / or reader as described herein. Resources may then be allocated to the groups of A-IoT devices by the network entity and / or reader.
[0123] It should be noted that though certain aspects are discussed with respect to grouping A-IoT devices as an illustrative example, grouping of other types of devices may similarly be performed using techniques discussed herein. Further, certain aspects are discussed herein with respect to a network entity and / or reader acting as a grouping device as an illustrative example. However, it should be noted that grouping may be performed by any suitable grouping device according to the techniques discussed herein. Further, certain aspects are discussed with respect to grouped devices (e.g., A-IoT devices) communicating with the grouping device using resources allocated to the grouped devices as an illustrative example. However, it should be noted that the grouped devices may communicate with any suitable device (s) using the allocated resources.
[0124] For example, with respect to FIG. 5C, in certain aspects, the network entity 516 may act as a grouping device, the tag 506 may be a grouped device, and the reader 504 may be the device the grouped device communicates with using allocated resources. In certain aspects, the network entity 516 may act as a grouping device, the tag 506 may be a grouped device, and the network entity 516 may be the device the grouped device communicates with using allocated resources indirectly via the reader 504. In certain aspects, the reader 504 may act as a grouping device, the tag 506 may be a grouped device, and the reader 504 may be the device the grouped device communicates with using allocated resources.
[0125] For example, with respect to FIG. 5B, in certain aspects, the reader 504 may act as a grouping device, the tag 506 may be a grouped device, and the reader 504 may be the device the grouped device communicates with using allocated resources.
[0126] FIG. 7A depicts a grouping identifier (ID) 700 (e.g., Layer 1 ID) for each A-IoT device. The grouping identifier 700 may include a group ID 706 indicating to which group the A-IoT device belongs. The grouping identifier 700 may further include an identifier 708 (also referred to as a process identifier or pID) of the A-IoT device within the group. The pID may be a unique identifier to the A-IoT device within the group, but different groups may reuse the same pID. In certain aspects, the pID 708 may be short (e.g., two bits) .
[0127] In certain aspects, the grouping identifier 700 for an A-IoT device is determined during a random access procedure, such as whereby one or more A-IoT devices attempt to connect with a grouping device (e.g., network entity and / or reader) . For example, the grouping device may send, e.g., broadcast, a FL packet indicating the grouping device is starting a round of random access. Though described as an “FL packet” the FL packet may be any suitable message or packet, depending on the grouping device. Each of one or more A-IoT devices (e.g., performing random access to the grouping device) may respond to the FL packet by sending, to the grouping device, a respective message (e.g., MsgA) indicating the A-IoT device is performing random access, the respective message including an identifier of the A-IoT device, such as a unique identifier and / or contention resolution identifier (CRI) . In certain aspects, the respective message for an A-IoT device may include a random access preamble and / or identifier of the grouping device. In certain aspects, the respective message for an A-IoT device may include additional information, such as an amount of data pending for communication at the A-IoT device and / or a set of indications of one or more additional factors. A set as used herein may include one or more elements.
[0128] In certain aspects, the grouping device may group the A-IoT devices into a same group (e.g., as indicated by the group ID 706) based on which A-IoT devices are successfully accessed in a current round of a random access procedure (e.g., the grouping device configures semi-persistent “rounds” of time where A-IoT devices can attempt to connect to the n grouping device, such as via a random access channel (RACH) procedure for each round) . In some embodiments, the groupings of A-IoT devices may be performed on the fly.
[0129] In certain aspects, the FL packet may further include a configuration of a resource allocation, such as a pool of resources (also referred to as access occasions) . FIG. 7B depicts a resource allocation 701. For example, a grouping device may transmit an FL packet 710, where the FL packet 710 triggers a start of a “round” for one or more A-IoT devices to attempt to establish communications with the grouping device. In some embodiments, the FL packet 710 may include a group ID 706. In some embodiments, the FL packet 710 does not include a group ID. In certain aspects, the FL packet 710 includes an indication or configuration of an access occasion (AO) pool 712. The AO pool 712 may define a plurality of AOs. In certain aspects, the AO pool may occur periodically in time, where each periodic occurrence includes an instance of the plurality of AOs. An AO may refer to a communications resource (e.g., time resource, frequency resource, spatial resource, code for code division, a combination of any thereof, or the like) . For example, an A-IoT device allocated one or more AOs may be able to communicate (e.g., transmit) on the one or more AOs, such as communicate one or more signals including one or more messages, such as including data, feedback information, command response, etc.
[0130] For example, the AO pool 712 may include a set of (e.g., contiguous) resources in the time and frequency domains that can be used, for example, for random access or traffic data. While the AO pool 712 is shown as a set of resources in the frequency domain, it is to be understood that the AO pool 712 may include resources in the time domain, the frequency domain, the code domain, hopping across time-frequency resources, or a combination thereof.
[0131] As an example, the AO pool 712 may be used by each of one or more A-IoT devices for transmitting a first message (e.g., MsgA) indicating the A-IoT device is performing random access as discussed. For example, three (3) A-IoT devices may transmit the first message using a first instance of a plurality of AOs of the AO pool 712. For example, the three (3) A-IoT devices may include a device X, a device Y, and a device Z.
[0132] FIG. 7C depicts a resource allocation 702 that allocates AOs to A-IoT devices. For example, the resource allocation 702 may map identifiers from the three (3) A-IoT devices that transmitted the first message to AOs 720-724, which may be AOs of the AO pool 712. It should be noted that AOs may be allocated to more or fewer devices, and more than one AO may be allocated to a given device. In certain aspects, AOs 720-724 may be a plurality of AOs that occur periodically. Accordingly, allocation of AOs 720-724 may refer to allocation of one or more instances of AOs 720-724.
[0133] For example, in response to the first messages, the grouping device may send a respective second message (e.g., MsgB) to each of the A-IoT devices to be included in a group, the second messages further indicating a pID of each A-IoT device. The second message may include an identifier of the A-IoT device for which the second message is addressed, such as a CRI of the A-IoT device. The second message may include the group ID 706 of a group. In certain aspects, the FL packet 710 may include the group ID 706 of the group. Accordingly, an A-IoT device receiving a second message with an identifier of the A-IoT device may determine a group ID 706 of the A-IoT device based on the FL packet 710 and / or second message, and a pID 708 of the A-IoT device based on the second messages.
[0134] As shown, the grouping device sends a second message 714 for device Y, a second message 716 for device Z, and a second message 718 for device X, in that order. Each A-IoT device X, Y, and Z, may receive each of second messages 716-718. The order with which the grouping device sends each second message 716-718 may be determined based on when each first message from each device was received at the grouping device. For example, the grouping device may receive the first message from the device Y first, from the device Z second, and from the device X third. Additionally or alternatively, the grouping device may send each second message to each respective device based on different criteria, such as a scrambling code used by the device, an identifier value of the device, etc.
[0135] In certain aspects, the order with which the grouping device sends each second message to each respective device may indicate a time domain order mapping to each pID for each A-IoT device in a group. For example, the device Y may determine its pID is ‘1’ in the group based on the second message 714 being sent first, the device Z may determine its pID is ‘2’ in the group based on the second message 716 being sent second, and the device X may determine its pID is ‘3’ in the group based on the third message 718 being sent third.
[0136] Subsequently, the respective pIDs in the group may indicate or map to AOs, such as resource indexes of AOs, allocated for each of the A-IoT devices. For example, the device Y may be allocated a first AO 720 for communications after the RACH procedure is completed based on its pID of ‘1, ’ the device Z may be allocated a second AO 722 for communications after the RACH procedure is completed based on its pID of ‘2, ’ and the device X may be allocated a third AO 724 for communications after the RACH procedure is completed based on its pID of ‘3. ’ In some cases, each device implicitly determines which AOs are allocated to the device based on the pID. For example, device may be configured to divide the AO pool into sets of AOs, where a number of sets is equal to a number of devices in the group (e.g., based on the number of second messages) . The device may then select a set of AOs corresponding to the pID of the device. For example, the AOs may be divided based on frequency, and the first pID is associated with the first lowest frequency range, the second pID with the second lowest frequency range, etc.
[0137] In some embodiments, the A-IoT devices may use these allocated AOs for communications, such as with a network entity and / or reader, until a next “round” of time where A-IoT devices can attempt to connect to the grouping device is triggered and / or started. Additionally or alternatively, the A-IoT devices may use these allocated AOs for communications, such as with the network entity and / or reader, until each A-IoT device finishes communicating, such as with the network entity and / or reader.
[0138] FIG. 7D depicts a resource allocation 703 that allocates AOs to A-IoT devices. For example, the resource allocation 703 may map identifiers from the three (3) A-IoT devices that transmitted the first message to AOs 720-724, which may be AOs of the AO pool 712. It should be noted that AOs may be allocated to more or fewer devices, and more than one AO may be allocated to a given device. In certain aspects, AOs 720-724 may be a plurality of AOs that occur periodically. Accordingly, allocation of AOs 720-724 may refer to allocation of one or more instances of AOs 720-724.
[0139] In the example of FIG. 7D, the grouping device may transmit a single second message 726 that includes a first CRI 728 corresponding to the device Y, a second CRI 730 corresponding to the device Z, and a third CRI 732 corresponding to the device X. The second message 726 may include a group ID 706 of the group to be assigned to the A-IoT devices. The second message 726 may include an indicator of a size (e.g., number of devices) of the group. Rather than using the timing at which the second messages are sent to determine the pID to indicate the mapping to AOs as described with reference to FIG. 7C, the order of the CRIs may be used to determine the pID for each device that indicates or maps to AOs allocated for each of the A-IoT devices (e.g., such that the device Y is mapped to pID 1 associated with the first AO 720, the device Z is mapped to pID 2 associated with the second AO 722, and the device X is mapped to pID 3 associated with the third AO 724) . In some embodiments, the first CRI 728, the second CRI 730, and the third CRI 732 may be truncated CRIs and / or may be the full CRIs for each device. In certain aspects, the CRI or truncated CRI itself may be the pID.
[0140] FIG. 7E depicts a resource allocation 704 that allocates and / or maps AOs to devices, such as each of the three (3) A-IoT devices that transmitted the first message as described with reference to FIG. 7B. It should be noted that AOs may be allocated to more or fewer devices, and more than one AO may be allocated to a given device. In certain aspects, AOs 720-724 may be a plurality of AOs that occur periodically. Accordingly, allocation of AOs 720-724 may refer to allocation of one or more instances of AOs 720-724. In certain aspects, resource allocation 704 is performed after an initial resource allocation whereby A-IoT devices are assigned a group ID 706.
[0141] For example, the grouping device may send an FL packet 734 that includes an indication or configuration of an AO pool, such as AOs 720-724. The FL packet 734 may further include a group ID of the group to which the AO pool is allocated. Devices in the group may receive the FL packet 734, identify the AO pool is for the group based on the group ID, and determine which AOs are allocated to each device based on the pID determined as discussed above.
[0142] FIG. 8 depicts a process flow 800 for communications between a reader 802 and one or more A-IoT devices 804. The process flow 800 may include operations for the reader 802 to configure, map, and / or indicate AOs to the one or more A-IoT devices 804 as described herein for enabling communications between the reader 802 and the one or more A-IoT devices 804. The reader 802 may represent a network entity, reader device, reader, etc., as described with reference to FIGS. 5A-7E. Additionally, the one or more A-IoT devices 804 may represent tags, RFID tags, passive UEs, backscattering UEs, etc., as described with reference to FIGS. 5A-7E.
[0143] At 806, a first round may be triggered and / or started for the one or more A-IoT devices 804 to attempt to establish a connection with the reader 802. For example, the first round may be triggered and / or started based on the reader 802 sending a FL packet that can be received by the one or more A-IoT devices 804. In some embodiments, the FL packet may include an indication and / or configuration of a group ID (e.g., specific to the first round) .
[0144] At 808, as part of the first round, the reader 802 and the one or more A-IoT devices 804 may perform a random access procedure (e.g., two-step RACH procedure) to establish the connection. In the random access procedure, based on receiving the FL packet, at least one of the one or more A-IoT devices 804 may send a first random access message (e.g., MsgA) to the reader 802 (e.g., using an AO pool) . Subsequently, the reader 802 may configure and / or assign (e.g., implicitly or explicitly) pIDs (e.g., based on CRIs) to each A-IoT device that sends a first random access message. For example, the reader 802 may configure and / or assign the pIDs based on when, in time, a second random access message (e.g., MsgB) is sent to each A-IoT device that sent a first random access message and / or based on an order of respective CRIs in the second random access message for each A-IoT device that sent a first random access message. As described previously, the pIDs may then map to resources 810 (e.g., AOs) allocated to each of the A-IoT devices that performed the random access procedure. That is, the reader 802 may allocate resources 810 (e.g., AOs) for further communications to A-IoT devices with the same group ID and that performed the random access procedure at 808
[0145] At 812, further communications between the reader 802 and the one or more A-IoT devices may occur on the resources 810 allocated to the A-IoT devices with the same group ID and that performed the random access procedure at 808. In some embodiments, the further communications may include device memory read / write, device lock / unlock, other commands, etc.
[0146] At 814, a second round may be triggered and / or started for other A-IoT devices of the one or more A-IoT devices 804 to attempt to establish a connection with the reader 802 that did not successfully establish a connection during the first round. For example, the second round may be triggered and / or started based on the reader 802 sending another FL packet that can be received by the one or more A-IoT devices 804. In some embodiments, the FL packet may include an indication and / or configuration of a group ID (e.g., specific to the second round) . Additionally or alternatively, when the second round is triggered, all of the one or more A-IoT devices 804 can attempt to establish a connection with the reader 802, and those A-IoT devices who failed in the first round can also attempt to establish a connection as if the second round is the first round for them.
[0147] At 816, as part of the second round, the reader 802 and the one or more A-IoT devices 804 may perform a random access procedure to establish the connection. In the random access procedure, the reader 802 may configure the group ID and pIDs in the group as described previously but for A-IoT devices that performed the random access procedure during 816. Subsequently, the pIDs may then map to resources 818 (e.g., AOs) allocated to each of the A-IoT devices that performed the random access procedure at 816. That is, the reader 802 may allocate resources 818 (e.g., AOs) for further communications to A-IoT devices with the same group ID and that performed the random access procedure at 816.
[0148] At 820, further communications between the reader 802 and the one or more A-IoT devices may occur on the resources 818 allocated to the A-IoT devices with the same group ID and that performed the random access procedure at 816. In some embodiments, the further communications may include device memory read / write, device lock / unlock, other commands, etc.
[0149] FIG. 9 depicts an example aspect of a resource allocation 900 with different amounts of data. The resource allocation 900 may be used to allocate resources to one or more A-IoT devices to enable communications for the one or more A-IoT devices and a network entity and / or reader as described herein. For example, a grouping device may send a first FL packet 902 that triggers and / or starts a round for the A-IoT devices to establish a connection. Additionally, the first FL packet 902 may allocate AOs to devices, such as three (3) AOs for three (3) respective A-IoT devices in a group, such as a device X, a device Y, and a device Z (e.g., based on assigned or determined pIDs for the devices) . In some embodiments, the grouping device may send a second FL packet 904 to the group that includes the three (3) A-IoT devices. In response to the first FL packet 902 and / or second FL packet 904, each of the devices in the group may have respective information 906 to send back to the network entity and / or reader (e.g., in the allocated (3) AOs) . For example, the device X may send (e.g., transmit (TX) ) a message (e.g., data) in a first AO 908, the device Y may send a message in a second AO 910, and the device Z send a message a in a third AO 912.
[0150] However, in some embodiments, A-IoT devices in a same group can have different amounts of data to transmit. For example, the network entity and / or reader may read device memory of each A-IoT device in the group, and the different devices may have different amounts of data in memory to send to the network entity and / or reader. In the example of FIG. 9, the device X may have 100 bits in memory to send, the device Y may have 200 bits in memory to send, and the device Z may have 300 bits in memory to send.
[0151] In some embodiments, the grouping device may support a “group-common” resource allocation for the A-IoT devices in a group. The group-common resource allocation may include that devices in the same group use the same amount of communication resources, and in some cases a same data rate or modulation coding scheme (MCS) for communications. However, when the different devices have different amounts of data to transmit, the “group-common” resource allocation may result in low efficiency.
[0152] Accordingly, the techniques and signaling described herein may provide for arranging A-IoT devices into groups based on one or more factors and allocating resources to the groups of devices. For example, the grouping device may group A-IoT devices into respective groups based on which A-IoT devices have similar amounts of data for communication and / or based on additional factors as discussed, which may be indicated by the A-IoT devices, which will be described in greater detail with reference to FIGS. 10 and 11. In some embodiments, the grouping device may also send one or more configurations of one or more pools of AOs allocated to groups of A-IoT devices for communications.
[0153] Additionally or alternatively, the grouping device may dynamically manage the groups of A-IoT devices by indicating which A-IoT devices are not included in a group anymore, which A-IoT devices are to stay in a group, which A-IoT devices are to be added to a group, or a combination thereof, which will be described in greater detail with reference to FIG. 12.
[0154] Additionally or alternatively, the grouping device may select subgroups of A-IoT devices in a group for resource allocations. For example, the grouping device may indicate: whether a message is addressed to the full group or to a subgroup of the group, a size of the subgroup, a group common identifier and one or more identifiers of individual A-IoT devices to include or not include in the subgroup, or any combination thereof, which will be described in greater detail with reference to FIG. 13. Additionally or alternatively, the grouping device may allocate a same amount of resources to each A-IoT device in a same group. For example, the reader may allocate the resources to each A-IoT device in a group based on a largest amount of data pending among the A-IoT devices of the group and / or may indicate a same allocation of resources to the group for multiple time periods until all A-IoT devices in the group have no data pending for communications, which will be described in greater detail with reference to FIG. 14.
[0155] In certain aspects, to mitigate the previously described problem of different A-IoT devices in a same group having different amounts of data to communicate or different other additional factors, a group may include A-IoT devices with similar amounts of data for communication and / or other factors being categorized or assigned into a same group. For example, the grouping device may group A-IoT devices into groups, where each group is associated with a range of amounts of data for communication. For example, the grouping device may define multiple ranges of amount of data to be communicated, such as to divide the devices into groups, such that each range is associated with a group. A device may be assigned to a group where the amount of data to communicate at the device is within the range associated with the group.
[0156] In certain aspects, each group is further or instead associated with one or more values or ranges of values of one or more of the additional factors discussed, such that devices are further grouped based on the one or more additional factors. For example, multiple groups may be associated with the same range of amounts of data for communication, but different value (s) or range (s) of values for one or more additional factors. A device having an amount of data and value (s) for the one or more additional factors that fall within value (s) or range (s) of value (s) associated with a group may then be assigned to the group.
[0157] Accordingly in some embodiments, for grouping A-IoT devices into groups based on amounts of data for communication and / or additional factors, the grouping device may categorize or assign multiple groups per “round” (e.g., for A-IoT devices to attempt to establish communications with the network entity and / or reader) .
[0158] In the example of FIG. 10, different groups are shown being allocated different resources, where the different groups may be for a same “round. ” For example, the grouping device may assign one or more A-IoT devices to a first group and one or more A-IoT devices to a second group. For example, the first group (e.g., group ‘X’ ) may include a first A-IoT device (e.g., device X_1) , a second A-IoT device (e.g., device X_2) , and a third A-IoT device (e.g., device X_3) . Additionally, the second group (e.g., group ‘Y’ ) may include a first A-IoT device (e.g., device Y_1) , a second A-IoT device (e.g., device Y_2) , and a third A-IoT device (e.g., device Y_3) .
[0159] As indicated above, different devices with different amounts of data for communication and / or different value (s) for one or more additional factors may be categorized to different groups. For example, each group may be associated with a respective range of amounts of data pending for communication. In some embodiments, the grouping device may determine each of the A-IoT devices amounts of data for communication and / or different value (s) for one or more additional factors in a random access stage (e.g., during a random access procedure as described with reference to FIG. 8) . For example, when the A-IoT devices send a first message of a random access procedure (e.g., a MsgA) , each of the A-IoT devices may indicate an amount of data pending for communication. Additionally or alternatively, each of the A-IoT devices may indicate an amount of data pending for communication in a separate message (e.g., during the random access procedure or outside the random access procedure) . In some embodiments, when assigning each A-IoT device to a corresponding group, the grouping device may send a respective indication of a group to which the A-IoT device is assigned, such as described with respect to FIGs. 7A-7E.
[0160] Subsequently, after assigning the A-IoT devices to the respective groups, the grouping device may send respective messages (e.g., FL packets, second messages (e.g., MsgB) ) to each group to indicate for each A-IoT device in each group an allocation of AOs, such as discussed with respect to FIGs. 7A-7E. In certain aspects, the grouping device may send a first message 1002 to the first group (e.g., group ‘X, ’ which includes A-IoT devices X_1, X_2, X_3) indicating for each A-IoT device in the first group to report their respective data and / or an allocation of AOs. In the example of FIG. 10, the first group may include A-IoT devices that have approximately 100 bits to send each. Accordingly, each A-IoT device in the first group may send their respective data using an AO sub-pool 1004 assigned to the first group in respective AOs mapped for each A-IoT device in the first group (e.g., based on respective pIDs for each A-IoT device as described previously) . For example, the reader may read 90 bits from the first A-IoT device of the first group (e.g., device X_1) in a first AO 1006, 80 bits from the second A-IoT device of the first group (e.g., device X_2) in a second AO 1008, and 100 bits from the third A-IoT device of the first group (e.g., drvice X_3) in a third AO 1010.
[0161] Additionally or alternatively, the grouping device may send a second message 1012 to the second group (e.g., group ‘Y, ’ which includes A-IoT devices Y_1, Y_2, Y_3) indicating for each A-IoT device in the second group to report their respective data and / or an allocation of AOs. In the example of FIG. 10, the second group may include A-IoT devices that have approximately 50 bits to send each. Accordingly, each A-IoT device in the second group may send their respective data using an AO sub-pool 1014 assigned to the second group in respective AOs mapped for each A-IoT device in the second group (e.g., based on respective pIDs for each A-IoT device as described previously) . For example, the reader may read 30 bits from the first A-IoT device of the second group (e.g., device Y_1) in a first AO 1016, 40 bits from the second A-IoT device of the second group (e.g., device Y_2) in a second AO 1018, and 50 bits from the third A-IoT device of the second group (e.g., device Y_3) in a third AO 1020.
[0162] FIG. 11 depicts an example aspect of a grouping configuration 1100 for grouping A-IoT devices from a large AO pool. The grouping configuration 1100 may include a grouping of multiple A-IoT devices into respective groups based on amounts of pending data for communication for each of the multiple A-IoT devices and / or additional factors.
[0163] In the example of FIG. 11, multiple groups (e.g., of A-IoT devices) can be generated and allocated AOs from a large AO pool 1102 (e.g., for a random access procedure, such as a RACH procedure) . In some embodiments, the large AO pool 1102 may be used by the multiple A-IoT devices for one or more of the multiple A-IoT devices to send a first message of a random access procedure (e.g., MsgA of a random access procedure) . For example, a grouping device may send a first FL packet 1104 to trigger the start of a round for the A-IoT devices to attempt to establish a connection with the grouping device. Additionally, in some embodiments, the first FL packet 1104 may include an indication of the large AO pool 1102. For example, the grouping device may send one or more configurations of one or more pools of AOs (e.g., in the large AO pool 1102) allocated to the multiple groups (e.g., in the first FL packet 1104 or in another message) . After receiving the first FL packet 1104, one or more A-IoT devices may send a first message of a random access procedure to the grouping device using the large AO pool 1102.
[0164] Subsequently, after receiving one or more first messages of a random access procedure from respective A-IoT devices, the grouping device may include different group IDs in different FL group-common packets to indicate which FL group-common packets are intended for which groups. For example, the grouping device may send respective group-common second messages of the random access procedure (e.g., group-common MsgB) to each assigned group of A-IoT devices.
[0165] In the example of FIG. 11, the grouping device may send a first FL group-common packet 1106 that includes a group-common second message of the random access procedure for an A-IoT device Z_1 through an A-IoT device Z_10. In some embodiments, if no data is ready for communication for one or more A-IoT devices, the grouping device may not configure a grouping ID to those A-IoT devices. For example, the grouping device may determine there is no data for communication for the A-IoT device Z_1 to the A-IoT device Z_10, which may indicate there is no need of resources for further communication for those A-IoT devices and, thus, no need of grouping the A-IoT device Z_1 through the A-IoT device Z_10 to a group.
[0166] Additionally or alternatively, if the network entity and / or reader determines one or more A-IoT devices do have data to communicate, the grouping device may group the one or more A-IoT devices into respective groups (e.g., based on the amount of data pending for communication for each of the one or more A-IoT devices as described with reference to FIG. 10) and configure group IDs to the one or more A-IoT devices.
[0167] In the example of FIG. 11, the grouping device may send a second group-common FL packet 1108 that includes a group-common second message of the random access procedure for a group ‘X’ that includes an A-IoT device X_1 through an A-IoT device X_8. In some embodiments, the grouping device may determine each A-IoT device in the group ‘X’ (e.g., A-IoT device X_1 through A-IoT device X_8) may each have a small amount of data to communicate and each need resource (s) for further communication. Accordingly, the second group-common FL packet 1108 may implicitly or explicitly indicate a mapping of respective AOs 1110 to each of the A-IoT devices in the group ‘X’ (e.g., as described with reference to FIGS. 7A–7E) for each of the A-IoT devices to communicate their small amount of data.
[0168] Additionally or alternatively, the grouping device may send a third group-common FL packet 1112 that includes a group-common second message of the random access procedure for a group ‘Y’ that includes an A-IoT device Y_1 through an A-IoT device Y_6. In some embodiments, the grouping device may determine each A-IoT device in the group ‘Y’ (e.g., A-IoT device Y_1 through A-IoT device Y_6) may each have a large amount of data to communicate and each need resource (s) for further communication. Accordingly, the third group-common FL packet 1112 may implicitly or explicitly indicate a mapping of respective AOs 1114 to each of the A-IoT devices in the group ‘Y’ (e.g., as described with reference to FIGS. 7A–7E) for each of the A-IoT devices to communicate their large amount of data.
[0169] In some embodiments, in addition to or alternative to assigning A-IoT devices to respective groups based on respective amounts of data each A-IoT device has pending for communication (e.g., a buffer and / or memory status-based grouping method) , the grouping device may consider other factors and / or respective sets of indications from each of the A-IoT devices to assign the groups. That is, the grouping device may assign the A-IoT devices into groups based on the respective amounts of data each A-IoT device has pending for communication, the other factors, the respective sets of indications, or a combination thereof.
[0170] In some embodiments, the other factors and / or respective sets of indications from each of the A-IoT devices may include, but are not limited to, one or more of a pathloss between the device and another device to which the data is to be communicated, distance between the device and another device to which the data is to be communicated, energy state of the device (e.g., remaining battery) , error rates of the device (e.g., bit error rate (BER) , block error rate (BLER) such as for communications with another device to which the data is to be communicated, a number of contiguous failed decodings of signals by the device such as signal from another device to which the data is to be communicated, acknowledgment (ACK) feedback (e.g., ACK or negative ACK (NACK) ) for a previous communication by the device such as from another device to which the data is to be communicated, channel condition (s) (e.g., received signal strength indicator (RSSI) , reference signal received power (RSRP) , reference signal received quality (RSRQ) , etc. ) between the device and another device to which the data is to be communicated, etc.
[0171] FIG. 12 depicts an example aspect of a dynamic group management configuration 1200 for grouping A-IoT devices. For example, a grouping device may dynamically manage a group of A-IoT devices after the groups have been assigned. That is, after the initial groups of A-IoT devices have been configured and / or assigned (e.g., based on amounts of pending data for the A-IoT devices as described with reference to FIGS. 10 and 11, when the A-IoT devices successfully establish connections with the grouping device as described with reference to FIGS. 7A-8, based on other factors and / or indications as described with reference to FIG. 11, etc. ) , the grouping device may indicate (e.g., via a groupcast message) which A-IoT devices are not included in a group anymore, which devices are to remain in the group, which A-IoT devices are being added to the group, or a combination thereof.
[0172] For example, the grouping device may explicitly indicate a specific A-IoT device (e.g., an A-IoT device X_1) is no longer in its assigned group (e.g., group ‘X’ ) . Additionally or alternatively, the network entity and / or reader may implicitly indicate for the specific A-IoT device (e.g., the A-IoT device X_1) to finish communications, which may result in the specific A-IoT device being removed from the group once the communications are finished. In some embodiments, the network entity and / or reader may explicitly indicate (e.g., via a groupcast message) which A-IoT devices are to remain in the group. After dynamically adjusting the group (e.g., removing and / or adding A-IoT devices to a group) , the remaining A-IoT devices in the group may automatically adjust their pIDs, which may adjust which AOs are mapped to which A-IoT devices. In some embodiments, the dynamic group management configuration 1200 may be suitable for a multiple-shot allocation scheme. Additionally, the grouping device may use PHY or MAC signaling to dynamically manage the group (s) of A-IoT devices.
[0173] In the example of FIG. 12, the grouping device may send a first FL packet (or other message, such as MsgB) 1202 that includes an indication of an AO sub-pool 1204 (e.g., for small data communication) that includes three (3) AOs for a group ‘X. ’ Accordingly, a first A-IoT device in the group ‘X’ (e.g., an A-IoT device X_1) may use a first AO to communicate, a second A-IoT device in the group ‘X’ (e.g., an A-IoT device X_2) may use a second AO to communicate, and a third A-IoT device in the group ‘X’ (e.g., an A-IoT device X_3) may use a third AO to communicate. For example, the grouping device may read 100 bits from each A-IoT device in the group ‘X. ’
[0174] Subsequently, in the example of FIG. 12, the grouping device may send a second FL packet 1206 that includes an indication for the A-IoT devices in the group ‘X’ to continue reporting small data and an indication to remove the third A-IoT device (e.g., the A-IoT device X_3) from the group ‘X. ’ Additionally or alternatively, the second FL packet 1206 may include an indication for the first A-IoT device (e.g., the A-IoT device X_1) and the second A-IoT device (e.g., the A-IoT device X_2) to remain in the group ‘X. ’ Accordingly, the remaining A-IoT devices in the group ‘X’ may use an AO sub-pool 1208 for small data communication. For example, the first A-IoT device may use the first AO to communicate, and the second A-IoT device may use the second AO to communicate. Additionally, based on the third A-IoT device being removed from the group ‘X, ’ the network entity and / or reader may further read an extra 100 bits from the first A-IoT device and the second A-IoT device in the group ‘X. ’
[0175] Subsequently, in the example of FIG. 12, the grouping device may send a third FL packet 1210 that includes an indication for the A-IoT devices in the group ‘X’ to continue reporting small data and an indication to remove the second A-IoT device (e.g., the A-IoT device X_2) from the group ‘X. ’ Additionally or alternatively, the third FL packet 1210 may include an indication for the first A-IoT device (e.g., the A-IoT device X_1) to remain in the group ‘X. ’ Accordingly, the remaining A-IoT device in the group ‘X’ may use an AO sub-pool 1212 for small data communication. For example, the first A-IoT device may use the first AO to communicate. Additionally, based on the second A-IoT device also being removed from the group ‘X, ’ the network entity and / or reader may further read an extra 100 bits from the first A-IoT device in the group ‘X. ’
[0176] FIG. 13 depicts an example aspect of a subgroup selection configuration 1300 for resource allocation for groups of A-IoT devices. For example, a grouping device may select a subgroup of A-IoT devices in a group for resource allocation after the groups have been assigned. That is, after the initial groups of A-IoT devices have been configured and / or assigned (e.g., based on amounts of pending data for the A-IoT devices as described with reference to FIGS. 10 and 11, when the A-IoT devices successfully establish connections with the grouping device as described with reference to FIGS. 7A-8, based on other factors and / or indications as described with reference to FIG. 11, etc. ) , the grouping device may select a subgroup of A-IoT devices from the group to allocate resources (e.g., AOs) for the A-IoT devices in the subgroup to use for communications.
[0177] In some embodiments, the grouping device may send an FL packet 1302 that includes an indication of two (2) AOs allocated for communications for two (2) A-IoT devices. Additionally, the FL packet 1302 may include a groupcast indication 1304 (e.g., indicating the FL packet 1302 is a groupcast message to multiple A-IoT devices) and a source ID 1306 (e.g., corresponding to the grouping device) . In some embodiments, the grouping device may indicate a common group ID 1308 (e.g., group ID for a group ‘X’ ) and may indicate, using a bit 1310, whether the FL packet 1302 is addressed to the full group (e.g., the bit 1310 is ‘1’ ) or is addressed to a subset of the group (e.g., the bit 1310 is ‘0’ ) . Additionally, the grouping device may indicate a subgroup size 1312 (e.g., two (2) A-IoT devices in subgroup) and one or more pIDs 1314 (e.g., pID = 1, pID = 3) to indicate which A-IoT devices in the group are selected for the subgroup.
[0178] Accordingly, the A-IoT devices that correspond to the one or more pIDs 1314 may then use corresponding AOs to communicate. In the example of FIG. 13, the A-IoT device with the pID = 1 in the group ‘X’ may use a first AO 1316 for communications, and the A-IoT device with the pID = 3 in the group ‘X’ may use a second AO 1318 for communications. In some embodiments, the subgroup selection configuration 1300 may be suitable for a multiple-shot resource allocation (e.g., where multiple instances of AOs are allocated for the communications, such as across multiple time periods) . Additionally, unicast can be realized based on the grouping device selecting one (1) A-IoT device in a group. In some embodiments, the grouping device may indicate (e.g., in the FL packet 1302) which A-IoT devices in the group are not selected for the subgroup. In some embodiments, the pIDs can be a CRI and / or truncated CRI corresponding to each A-IoT device in a group.
[0179] FIG. 14 depicts an example aspect of a resource allocation configuration 1400 for groups of A-IoT devices. For example, based on the resource allocation configuration 1400, when a grouping device allocates resources (e.g., a size of each AO) to different A-IoT devices in a group, the grouping device may allocate a same amount of resources for the different A-IoT devices.
[0180] In some embodiments, for a one shot resource allocation (e.g., where one instance of AOs is allocated for the communications, such as in one time period) , the grouping device may allocate the resources to be large enough for the A-IoT device in the group with a largest buffer status (e.g., a largest amount of data pending for communication) . Additionally or alternatively, for a multiple-shot resource allocation the network entity and / or reader may repeat a group level resource allocation until all A-IoT devices in the same group finish communication.
[0181] In the example of FIG. 14, the grouping device may send a first FL packet 1402, e.g., that includes a random access message (e.g., MsgB) , for one or more A-IoT devices in a same group. For example, the first FL packet 1402 may include an indication of a group ID corresponding to a group (e.g., group ‘X’ ) that includes a first A-IoT device (e.g., an A-IoT device X_1) , a second A-IoT device (e.g., an A-IoT device X_2) , and a third A-IoT device (e.g., an A-IoT device X_3) . Additionally, the first FL packet 1402 may include an indication of an AO subpool 1404 for small data communication for the A-IoT devices in the group, where the AO subpool 1404 includes respective AOs of same resource sizes. For example, the first A-IoT device may use a first AO for communications, the second A-IoT device may use a second AO for communications, and the third A-IoT device may use a third AO for communications. In some embodiments, the network entity and / or reader may read 100 bits from each A-IoT device in the group.
[0182] In some embodiments, the grouping device may send a second FL packet 1406 that includes an indication for the A-IoT devices in the group (e.g., group ‘X’ ) to continue reporting small data in the AO subpool 1404. Accordingly, the first A-IoT device may use the first AO for communications, and the second A-IoT device may use the second AO for communications. However, the third A-IoT device may not have any more data to send, resulting in the third AO being empty. As such, the network entity and / or reader may read an extra 100 bits from the first A-IoT device and the second A-IoT device in the group.
[0183] In some embodiments, the grouping device may send a third FL packet 1408 that includes an indication for the A-IoT devices in the group (e.g., group ‘X’ ) to continue reporting small data in the AO subpool 1404. Accordingly, the first A-IoT device may use the first AO for communications. However, the second A-IoT device and the third A-IoT device may not have any more data to send, resulting in the second AO and the third AO being empty. As such, the network entity and / or reader may read an extra 100 bits from the first A-IoT device in the group.
[0184] FIG. 15 depicts an example aspect of a configuration 1500 for monitoring for messages for groups of A-IoT devices. In some cases, an A-IoT device may determine a corresponding order of A-IoT devices in a group (e.g., determine respective pIDs) based on messages in a random access procedure (e.g., MsgB, Msg2, or Msg4) , and such order can map to different resources. However, in some cases, a number of A-IoT devices being accessed and / or queried successfully in one round can be large (e.g., 32 A-IoT devices via 32 random access occasions) . As such, for a last (e.g., 32nd) A-IoT device to determine its order, the A-IoT device may need to monitor the previous 31 packets, which may be unreliable, such as due to packets dropping.
[0185] In the example of FIG. 15, an AO pool 1502 may be allocated for a first random access message transmission from one or more A-IoT devices (e.g., MsgA, that includes a preamble and CRI for each A-IoT device) . For example, 32 A-IoT devices may be able to transmit a first random access message in the AO pool 1502. Subsequently, a grouping device may respond with respective FL packets that include a second random access message (e.g., MsgB) for each A-IoT device that sent the first random access message.
[0186] For example, the grouping device may send a first FL packet 1504 including the second random access message for a first A-IoT device (e.g., A-IoT device Y) , a second FL packet 1506 including the second random access message for a second A-IoT device (e.g., A-IoT device Z) , and a thirty-second FL packet 1508 including the second random access message for a third A-IoT device (e.g., A-IoT device X) . Accordingly, each A-IoT device may determine its order (e.g., pID) based on when each FL packet is sent. For example, the first A-IoT device may determine its order is 1 (e.g., pID = 1) , the second A-IoT device may determine its order is 2, and the third A-IoT device may determine its order is 32. However, the third device may need to monitor the previous 31 packets; otherwise, its order may be wrong.
[0187] In some embodiments, based on a packet size limitation for the second random access message (e.g., MsgB packet size limitation) , multiple second random access messages (e.g., or multiple group common second random access messages) can be used as response to the first random access message transmissions in the AO pool 1502 (e.g., or a larger sized AO pool) . Additionally, an upper bound (e.g., N) of message packets an A-IoT device should monitor may be configured. As such, if no corresponding second random access message is received before the upper bound is met, an A-IoT device may assume the random access procedure failed. For example, if the upper bound is defined and / or configured as three (3) , an A-IoT device may monitor three (3) message packets for the second random access message at most. In some embodiments, the upper bound, N, may be a preconfigured value or may be dynamically configured (e.g., via broadcast, RRC signaling, etc. ) from the grouping device before a random access procedure is performed.
[0188] FIGS. 16A, 16B, and 16C depict various example aspects of resource allocations. In FIGS. 5A-15, the examples and techniques described mainly illustrate frequency-division multiplexed (FDMed) resources. However, the techniques described herein are not limited thereto, and the resources (e.g., AOs) allocated to A-IoT devices in groups can refer to time-division multiplexed (TDMed) resources, FDMed resources, code-division multiplexed (CDMed) resources, or any combination thereof.
[0189] For example, FIG. 16A may depict a resource allocation 1600 of an AO pool 1604 that includes multiple AOs that are FDMed (e.g., for A-IoT devices to send a first random access message, BL data, or other signals) . Additionally or alternatively, FIG. 16B may depict a resource allocation 1601 of an AO pool 1606 that includes multiple AOs that are TDMed (e.g., for A-IoT devices to send a first random access message, BL data, or other signals) . Additionally or alternatively, FIG. 16C may depict a resource allocation 1602 of an AO pool 1608 that includes multiple AOs that are multiplexed in the time and frequency domains (e.g., for A-IoT devices to send a first random access message, BL data, or other signals) . In some embodiments and as described in the examples of FIGS. 5A-15, one (1) A-IoT device is shown occupying one AO. However, one (1) A-IoT device may occupy multiple AOs.

[0218] Method 1800 begins at block 1805 with sending (e.g., to a grouping device, directly or indirectly via another device) an indication of an amount of data pending for communication.
