[0020] The disclosed technology provides implementations and examples for configuring channel state information reference signals for tracking in wireless communications.
[0021] Tasks such as the inventory of AIoT devices are typically initiated by the server on the core network side. However, the core network lacks awareness of the AIoT devices that a base station’s AIoT cell or AIoT-capable UEs under a base station can manage. Consequently, when the core network frequently conducts AIoT operations, such as inventory for a specific type or certain AIoT devices, it necessitates the initiation of AIoT commands / paging for AIoT UEs to multiple base stations. These base stations, in turn, need to initiate AIoT commands / paging for a large number of AIoT UEs and AIoT cells under their deployment, leading to substantial consumption of communication resources. This invention primarily addresses the issue by enabling the core network or base station to ascertain the devices managed by the corresponding cell or AIoT-capable UE before initiating AIoT commands / paging for AIoT UEs. This allows for the selection of appropriate network resources for initiating AIoT commands, thereby reducing network resource consumption.
[0022] BACKGROUND
[0023] The IoT (Internet of things) has gained significant interest due to its potential to improve efficiency and comfort. The goal is to deploy billions of small, low-power devices for various applications. However, powering all devices with batteries that need manual replacement or recharging is impractical, costly, and can pose environmental and safety issues. The digitalization of industries has opened new markets for IoT technologies that support batteryless devices or devices with energy storage that don't require manual intervention. The size of these devices must be small to be viable for target use cases.
[0024] Practical applications require small, simple batteryless devices or devices with limited energy storage that don't need manual recharging. Energy harvesters typically output 1μW to a few hundreds of μW. Current cellular devices may not be compatible due to their high peak power consumption. Barcodes and RFID have low power consumption but limited range, leading to labor-intensive operations or costly deployments.
[0025] Moreover, the lack of interference management scheme results in severe interference between RFID readers and capacity problems, especially in case of dense deployment. It is hard to support large-scale network with seamless coverage for RFID. Thus, ambient power-enabled IoT is born at the right moment.
[0026] In 3GPP Release 19 work plan, the following two typologies of ambient IoT will be supported. Typology 1 is shown in FIG. 1. Referring to FIG. 1, AIoT (Ambient IoT) device can send its AIoT information / data to base station directly and receives AIoT information / data from base station directly. Typology 2 is shown in FIG. 2. Referring to FIG. 2, in the AIoT system, considering the limited coverage area (e.g. transmission and / or reception range) of a base station and an IoT device, an intermediate node between the base station and the AIoT device may be used to extend the coverage area. Usually, NR UE or NR relay can be used as the intermediate node. The AIoT device can send its AIoT information / data to the base station via an AIoT capable UE and receives AIoT information / data from base station via AIoT capable UE.
[0027] Furthermore, a hybrid topology1 and topology2 might also be supported. Thus, a base station supporting AIoT can include one or more AIoT cells. Within these cells, the base station can directly communicate with AIoT devices. However, these AIoT cells have a certain coverage range, and devices not within the AIoT cell coverage range cannot directly communicate with the base station. In addition, the base station can deploy some AIoT capable UEs. In areas not covered by the AIoT cell, these UEs can act as intermediate nodes to assist the base station and devices in communication.
[0028] Tasks such as the inventory of AIoT devices are typically initiated by the server on the core network side. However, the core network lacks awareness of the AIoT devices that a base station’s AIoT cell or AIoT-capable UEs under a base station can manage. Consequently, when the core network frequently conducts AIoT operations, such as inventory for a specific type or certain AIoT devices, it necessitates the initiation of AIoT commands / paging for AIoT UEs to multiple base stations. These base stations, in turn, need to initiate AIoT commands / paging for a large number of AIoT UEs and AIoT cells under their deployment, leading to substantial consumption of communication resources.
[0029] Embodiment 1 -UE capability of AIoT Reporting
[0030] In this embodiment, there are two alternatives for UE reporting its AIoT capability to core network. FIG. 3 illustrates two example options for UE reporting AIoT capabilities to a core network based on some implementations of the disclosed technology.
[0031] Option 1: UE sends a NAS message to CN (Core Network) and includes UE AIoT capability information in the message.
[0032] Option2: UE sends a RRC message to the BS (Base Station) and includes UE AIoT capability information in the message. After the BS receives the RRC message, the BS sends UE AIoT capability information to CN via a NGAP message.
[0033] For Option1 and Option2, the UE AIoT capability information comprises a list of AIoT device type (s) supported by the UE.
[0034] Embodiment 2 -BS capability of AIoT Reporting
[0035] In this embodiment, the BS sends a NGAP message to the CN that includes BS AIoT capability information. FIG. 4 illustrates an example of AIoT reporting of the BS AIoT capability information from the base station to the core network based on some implementations of the disclosed technology.
[0036] The BS AIoT capability information comprises at least one of the following:
[0037] 1) at least one list of AIoT device types supported by one certain cell;
[0038] 2) a list of AIoT device types supported by the BS; or
[0039] 3) a list of AIoT cell ID (AIoT cell means a cell support direct communication with AIoT device) .
[0040] Embodiment 3 -CN requesting / subscribing the AIoT coverage of BS / cell
[0041] In this embodiment, the CN requests or subscribes the AIoT coverage information of at least one base station or a cell of the base station, to retrieve the AIoT devices that the base station or the AIoT cell can manage. FIG. 5 illustrates an example of a core net requesting or subscribing AIoT coverage of a base station or a cell of the base station based on some implementations of the disclosed technology. The AIoT coverage information refers to information about AIoT devices that can be managed by the base station / acell of the base station.
[0042] Step 0: The CN is aware of the BS AIoT capability of one or more BSs. The detail of the BS AIoT capability, and how CN retrieves the BS AIoT capability, which has been discussed in relation to Embodiment 2, can be applied in this implementation as well.
[0043] Step 1: Based on the BS AIoT capability of one or more BSs, the CN determines which device type can be managed by which BS / cell. The CN may be interested with coverage information of a specific type of AIoT devices for a specific BS / cell. Thus, the CN sends a NGAP message to one or more BSs to request / subscribe the AIoT coverage of BS, and includes at least one of the following in the message:
[0044] 1) a coverage query or subscription indication;
[0045] 2) a list of device types, indicating that only the specific type (s) of devices that can be managed by the cell or BS need to be reported; (Note: if this information is not present in the NGAP message, it means that all device types can be managed by the cell or the base station) ; or
[0046] 3) a list of cell IDs, indicating that the coverage information of only specific cell (s) needs to be reported (Note: if this information is not present in the NGAP message, it means that coverage information of all AIoT cells of the BS needs to be reported. ) .
[0047] Step 2: The BS sends or broadcasts a UU AIoT message to all AIoT devices within all or specific AIoT cell (s) of the BS, including a coverage query indication. In the implementations of the disclosed technology, “sending” can be used to include “broadcasting. ” Please note that in some implementations, this procedure can be initiated by the OAM (Operations, Administration, and Maintenance) or by the BS itself, which means that Step 1 may not be necessary in some implementations.
[0048] Step 3: Each device that receives the coverage query indication sends a UU AIoT message back to the BS to provide the coverage query result. Thus, the UU AIoT message from the device can provide information on the presence of the device. The UU AIoT message includes the device ID and, optionally, the device type for this device. In this way, the BS becomes aware of the devices managed by itself or by specific cell (s) .
[0049] Step 4: the BS filters the result received from the devices based on the coverage query or subscription received from CN in step 1 or OAM.
[0050] Step 5: The BS sends a NGAP message to the CN and includes the filtered AIoT coverage information of BS in the message. In the implementations, the information comprises at least one of the following:
[0051] 1) a list of IDs of AIoT devices supported by one certain cell of the base station;
[0052] 2) a list of IDs of AIoT devices supported by the BS;
[0053] 3) a list of AIoT devices of a specific type (s) supported by one certain cell of the base station;
[0054] 4) a list of AIoT device ID of specific device type (s) supported by the BS.
[0055] In this way, the CN becomes aware of the devices managed by itself or by specific cell (s) .
[0056] In the CN subscription case, the BS may periodically initiate Step 2, requesting devices to report their presence on a regular basis. If the information of the devices managed by itself or by specific cell (s) changes, the BS sends the updated AIoT coverage information of the BS to the CN.
[0057] Embodiment 4 -CN requesting / subscribing the AIoT coverage of AIoT capable UEs
[0058] FIG. 6 illustrates two example options a core network requesting or subscribing AIoT coverage of AIoT capable UEs based on some implementations of the disclosed technology.
[0059] Step 0: the CN is aware of the UE AIoT capability of one or more UEs. The details of the UE AIoT capability, and how CN retrieves the UE AIoT capability, which has been discussed in relation to Embodiment 1, can be applied in this implementation as well.
[0060] In this embodiment, The CN requests or subscribes the AIoT coverage information of at least one UE, to retrieve the AIoT devices that the UE can manage. The AIoT coverage information of UE refers to AIoT devices that can be managed by the UE. In this embodiment, there are two alternatives for CN to retrieve UE AIoT coverage information.
[0061] Option 1
[0062] Step 1: Based on the UE AIoT capability of one or more UEs, the CN determines which device type can be managed by which UE, the CN may be interested with AIoT coverage information of a specific type of a AIoT device for the specific UE. Then, the CN sends a NAS message to one or more UEs to request / subscribe the AIoT coverage of the UE. The NAS message may include at least one of the following:
[0063] 1) a coverage query or subscription indication;
[0064] 2) a list of device types, indicating that only the specific type (s) of AIoT devices that can be managed by the UE need to be reported; (Note: if this information is not present, means all device types) .
[0065] (Note: If UE is in RRC connected state, the BS routes the NAS message to the UE; otherwise, the BS pages the UE first, and the routes the NAS message to the UE if UE is paged) .
[0066] Steps 2, 3, and 4: After UE receives the NAS message, the Steps 2, 3, 4 of Option 1 are similar with Step 2, 3 in Embodiment 3 except that in this embodiment, it is the UE sending a UU AIoT message to all AIoT device within its coverage area, and each AIoT device responses to UE and it is the UE filtering the result received from the AIoT devices based on the detail coverage query or subscription received from NAS message.
[0067] Step 5: The UE sends a NAS message to the CN, and includes the filtered AIoT coverage information of UE in the message. The information comprises at least one of the following:
[0068] 1) at least one list of AIoT device ID supported by the UE;
[0069] 2) Cell ID and / or BS ID of UE connected or camped on; or
[0070] 3) at least one list of AIoT device ID of specific device type (s) supported by the UE.
[0071] In this way, the CN becomes aware of the devices managed by this UE.
[0072] In the CN subscription case, the UE may periodically initiate Step 2, requesting AIoT devices to report their presence on a regular basis. If the information of the devices managed by the UE cell (s) is changed, the UE sends the updated AIoT coverage information of the UE via NAS message to the CN.
[0073] Option 2
[0074] Step 1: Based on the UE AIoT capability of one or more UEs, the CN determines which device type can be managed by which UE, the CN may be interested with AIoT coverage information of specific type of AIoT device for specific UEs. Then, the CN sends a NGAP message to one or more UEs / BSs to request / subscribe the AIoT coverage of the one or more UEs, and includes at least one of the following in the message:
[0075] 1) a coverage query or subscription indication (Note: The NGAP message could be a NGAP paging message if UE is in CM IDLE state, or other message. if NGAP paging message, this indication refers to paging cause value) ;
[0076] 2) a list of device types, indicating that only the specific type (s) of devices that can be managed by the UE need to be reported; (Note: if this information is not present, means all device types need to be reported) ;
[0077] 3) a list of UE ID (s) to indicate the AIoT coverage information of interested UE (s) included in the list is required.
[0078] Step 2: Based on the received request / subscription, the BS sends UU paging message (if UE is not in RRC connected state) , otherwise RRC message to the corresponding interested UE, and includes at least one of the following in the message:
[0079] 1) a coverage query or subscription indication;
[0080] 2) a list of device types, indicating that only the specific type (s) of devices that can be managed by the UE need to be reported; (Note: if this information is not present, means all device types need to be reported) .
[0081] Steps 3, 4, and 5: After UE receives the message sent by the BS, Step 3, 4, and 5 which are same as Steps 2, 3, 4 in Option 1 in this embodiment are performed.
[0082] Step 6: The UE sends a RRC message / or user data (e.g., small user data) to the BS, and includes the filtered AIoT coverage information of the UE in the message. The information comprises at least one of the following:
[0083] 1) at least one list of AIoT device ID supported by the UE;
[0084] 2) Cell ID and / or BS ID of UE connected or camped on; or
[0085] 3) at least one list of AIoT device ID of specific device type (s) supported by the UE.
[0086] Step 6: The gNB sends a NGAP message to the CN and includes AIoT coverage status information of one or more UEs in the message.
[0087] In the CN subscription case, the BS may periodically initiate Step 2, requesting devices to report their presence on a regular basis. If the information of the devices managed by the UE is changed, the BS sends the updated AIoT coverage information of the UE to the CN.
[0088] Embodiment 5 -Using UE / BS AIoT coverage information to optimize network resource used for AIoT operation
[0089] FIG. 7 illustrates a flowchart for describing UE / BS AIoT coverage information used to optimize network resources for an AIoT operation based on some implementations of the disclosed technology.
[0090] Step 0: The CN is aware of the BS AIoT coverage information of one or more BSs, and UE AIoT coverage information of one or more UEs. The description provided in relation to Embodiment 3 and 4 regarding how CN retrieves BS / UE AIoT coverage information can be applied in this embodiment.
[0091] Step 1: Based on the BS AIoT coverage information of one or more BSs, and or UE AIoT coverage information of one or more UEs, the CN can decide a candidate resource for the operation of the interested devices. In this example, the candidate resource comprises at least one of the following:
[0092] 1) at lease one candidate AIoT cell for one or more AIoT devices;
[0093] 2) at lease one candidate AIoT cell for one or more types of AIoT device;
[0094] 3) at lease one candidate AIoT capable UE for one or more AIoT devices;
[0095] 4) at lease one candidate AIoT capable UE for one or more types of AIoT device;
[0096] 5) at lease one candidate BS for one or more devices; or
[0097] 6) at lease one candidate BS for one or more types of AIoT device.
[0098] In this step, CN may also consider UE history information, for example, UE last visited cells information stored in CN side for decision.
[0099] Step 2: CN sends the message to the BS to request the AIoT operation for interested devices. In the example, the message includes at least one of the following:
[0100] 1) at least one interested AIoT device;
[0101] 2) at least one interested type of AIoT device; or
[0102] 3) candidate resource.
[0103] Step 3: Upon receiving the AIoT operation request message from the CN, the BS further determines the resources to be used for AIoT operations for the requested devices. The decision process can be illustrated as follows:
[0104] If the candidate resource is not included in the message, the BS determines the resources to be used for AIoT operations based on the AIoT coverage information of the BS and / or the UE AIoT coverage information stored on the BS side.
[0105] If the candidate resource is included in the message, the BS determines the final resources to be used for AIoT operations based on the latest AIoT coverage information of the BS, and / or the latest UE AIoT coverage information stored on the BS side, and / or UE mobility information, and / or cell activation / deactivation information, and / or cell energy saving state.
[0106] Step 4: The BS performs the AIoT operation within the decided AIoT cells, and / or performs the AIoT operation assisted by the decided AIoT capable UEs. CN receives AIoT operation results from the UE or the network.
[0107] FIG. 8 illustrates an example of a wireless communication system (e.g., a long term evolution (LTE) , 5G or NR cellular network) that includes a BS 820 and one or more user equipment (UE) 811, 812 and 813.

The disclosed and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more them. The term “data processing apparatus” encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them. A propagated signal is an artificially generated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus.
[0137] A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a standalone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document) , in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code) . A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
[0138] The processes and logic flows described in this document can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit) .
[0139] Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for performing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
