[0071] Reduced Capability UEs were introduced in 3GPP Rel-17. This standard defines three different RedCap UE types—industrial sensors, video surveillance, and wearables—each with different battery life requirements. For example, for industrial sensors, the battery should last for at least several years. As a primary power conservation measure, the network can configure radio resource configurations for the UE, allowing the UE to periodically go into sleep mode. For example, this radio resource configuration may include discontinuous reception / extended discontinuous reception (DRX / eDRX).

[0072] However, in the current design, a cell (e.g. Figure 1 Therefore, a mechanism is needed to configure different radio resource configurations for the three different RedCap UE types supported by 3GPP Rel-17.

[0073] In addition, non-public networks (NPNs) are discussed in 3GPP WI16 for public network integrated NPNs (PNI-NPNs) deployed by public mobile network operators (MNOs). According to this standard, public MNOs should provide one or more interfaces for customers to perform authorized network control or configuration according to their agreements. For example, a customer may want to configure radio resource configuration (e.g., long eDRX cycle) for their redCap devices. Therefore, a mechanism is needed to configure radio resource configuration by PNI-NPN and / or by UE device type.

[0074] Therefore, the systems and methods discussed herein provide a mechanism for configuring different radio resource configurations for the three different RedCap UE types supported by 3GPP Rel-17. The systems and methods discussed herein also provide a mechanism for configuring radio resource configurations per PNI-NPN and / or per UE device type.

[0075] 1. Mobile communication technology and environment

[0076] Figure 1 An example wireless communication network and / or system 100 is shown in which the techniques disclosed herein may be implemented according to embodiments of the present disclosure. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100." Such an example network 100 includes a base station 102 (hereinafter referred to as "BS 102"; also referred to as a wireless communication node) and a user equipment device 104 (hereinafter referred to as "UE 104"; also referred to as a wireless communication device) that may communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. Figure 1 1 , BS 102 and UE 104 are contained within the respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating within its allocated bandwidth to provide adequate radio coverage to its intended users.

[0077] For example, BS 102 may operate with the allocated channel transmission bandwidth to provide sufficient coverage to UE 104. BS 102 and UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In the present disclosure, BS 102 and UE 104 are described herein as non-limiting examples of "communication nodes," which may generally practice the methods disclosed herein. According to various embodiments of the present solution, such communication nodes may be capable of wireless and / or wired communication.

[0078] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of the present solution is shown. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, the system 200 may be used in applications such as Figure 1 Data symbols are communicated (eg, transmitted and received) in a wireless communication environment such as the wireless communication environment 100 of FIG. 1 , as described above.

[0079] System 200 generally includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment device 204 (hereinafter referred to as "UE 204"). BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled to and interconnected with each other via a data communication bus 220 as needed. UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled to and interconnected with each other via a data communication bus 240 as needed. BS 202 communicates with UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0080] As will be understood by those skilled in the art, the system 200 may also include Figure 2Any number of other modules outside the modules shown. It will be understood by those skilled in the art that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any actual combination thereof. In order to clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are generally described in terms of their functions. Whether such functions are implemented as hardware, firmware, or software can depend on the specific application and the design constraints imposed on the entire system. People familiar with the concepts described herein can implement such functions in an appropriate manner for each specific application, but such implementation decisions should not be interpreted as limiting the scope of this disclosure.

[0081] According to some embodiments, the UE transceiver 230 may be referred to herein as an "uplink" transceiver 230, and includes a radio frequency (RF) transmitter and an RF receiver, each of which includes circuitry coupled to an antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time-duplexed manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as a "downlink" transceiver 210, and includes an RF transmitter and an RF receiver, each of which includes circuitry coupled to an antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplexed manner. The operations of the two transceiver modules 210 and 230 may be temporally coordinated such that the uplink receiver circuitry is coupled to the uplink antenna 232 for transmission and reception over the wireless transmission link 250 when the downlink transmitter is coupled to the downlink antenna 212. Rather, the operation of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 while the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is tight time synchronization with minimal guard times between changes in duplex direction.

[0082] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and to cooperate with an appropriately configured RF antenna arrangement 212 / 232 capable of supporting a specific wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that the present disclosure is not necessarily limited to application to specific standards and related protocols. Instead, the UE transceiver 230 and the base station transceiver 210 can be configured to support alternative or additional wireless data communication protocols, including future standards or variants thereof.

[0083] According to various embodiments, for example, BS202 can be an evolved Node B (eNB), a serving eNB, a target eNB, a femto station, or a micro station. In some embodiments, UE 204 can be implemented in various types of user equipment, such as mobile phones, smart phones, personal digital assistants (PDAs), tablet computers, laptop computers, wearable computing devices, etc. Processor modules 214 and 236 can be implemented or implemented with a general-purpose processor, content addressable memory, digital signal processor, application-specific integrated circuit, field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. In this way, the processor can be implemented as a microprocessor, a controller, a microcontroller, a state machine, etc. The processor can also be implemented as a combination of computing devices, for example, a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.

[0084] Furthermore, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein may be implemented directly in hardware, in firmware, in software modules executed by the processor modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 may be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, the memory modules 216 and 234 may be coupled to the processor modules 214 and 236, respectively, such that the processor modules 214 and 236 can read information from and write information to the memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 214 and 236. In some embodiments, each of the memory modules 216 and 234 may include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by the processor modules 214 and 236, respectively. The memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by the processor modules 214 and 236, respectively.

[0085] The network communication module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communication between the base station transceiver 210 and other network components and communication nodes configured to communicate with the network base station 202. For example, the network communication module 218 can be configured to support Internet or WiMAX services. In a typical deployment, and without limitation, the network communication module 218 provides an 802.3 Ethernet interface so that the base station transceiver 210 can communicate with a conventional Ethernet-based computer network. In this manner, the network communication module 218 can include a physical interface for connection to a computer network (e.g., a mobile switching center (MSC)). As used herein with respect to a specified operation or function, the terms "configured for," "configured to," and variations thereof refer to a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0086] The Open Systems Interconnection (OSI) model (referred to herein as the "OSI model") is a conceptual and logical arrangement that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that are open to interconnection and communication with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual set of services provided to the layers above and below it. The OSI model also defines a logical network and effectively describes computer packet transmission by using different layer protocols. The OSI model may also be referred to as a seven-layer OSI model or a seven-layer model. In some embodiments, the first layer may be a physical layer. In some embodiments, the second layer may be a media access control (MAC) layer. In some embodiments, the third layer may be a radio link control (RLC) layer. In some embodiments, the fourth layer may be a packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be a radio resource control (RRC) layer. In some embodiments, the sixth layer may be a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is another layer.

[0087] 2. Configure radio resource configuration by UE device type and / or network

[0088] Figure 3 A block diagram of an example environment for configuring radio resource configuration by UE device type and / or by network according to some embodiments of the present disclosure is shown. Environment 300 may include a public land mobile network (PLMN) 302 (sometimes referred to as "PLMN1"). Environment 300 may include a facility (Factory) 1 corresponding to a closed access group 1 (CAG1) 304. CAG1 304 may correspond to a first network slice (in Figure 3 The environment 300 may include a facility 2 corresponding to a closed access group 2 (CAG2) 306. CAG2 306 may correspond to a second network slice (shown as "Slice A" in FIG. Figure 3 shown as "Slice B" in FIG.

[0089] In some embodiments, a cell (e.g., Figure 1 BS102, Network, Figure 3 302 in the UE) and / or by network) can configure (e.g., initialize, adjust, etc.) radio resource configuration (e.g., eDRX / DRX) in system information and / or in radio resource control (RRC) signals, per UE device type (e.g., industrial sensor, video surveillance, and wearable device) and / or per network. For example, Figure 4 An example structure of a DownlinkConfigCommonSIB message according to some embodiments of the present disclosure is shown.

[0090] 2.1 Broadcasting DRX / eDRX Configuration Information

[0091] In some embodiments, a cell may broadcast (eg, transmit, send, etc.) a radio resource configuration (eg, DRX / eDRX) according to structure 400 .

[0092] In some embodiments, the cell may be shared by PLMN1 / PLMN1+CAG1 / PLMN1 / CAG2. In some embodiments, PLMN1 may be accessed from a public UE (e.g., Figure 1 In some embodiments, PLMN1+CAG1 may be deployed by Facility 1, where the 3GPP operator may create a separate slice for the customer (e.g., sometimes referred to as "Slice A"). In some embodiments, PLMN1+CAG2 may be deployed by Facility 2, where the 3GPP operator may create a separate slice for the customer (e.g., sometimes referred to as "Slice B").

[0093] Figure 5 An example table showing different UE types corresponding to CAG1 / CAG2 according to some embodiments of the present disclosure is shown. By facility 1, type 1 UE (industrial sensor) may correspond to preferred DRX configuration "A"; type 2 UE (video surveillance) may correspond to preferred DRX configuration "A"; and / or type 3 UE (wearable device) may correspond to preferred DRX configuration "B".

[0094] According to facility 2, type 1 UE (industrial sensor) can correspond to the preferred radio resource configuration (e.g., DRX) "C"; type 2 UE (video surveillance) can correspond to the preferred radio resource configuration (e.g., DRX) "C"; and / or type 3 UE (wearable device) can correspond to the preferred radio resource configuration (e.g., DRX) "B".

[0095] In some embodiments, pcch-ConfigSpecificList[0] may correspond to {in the network of PLMN+CAG1, UEType 1 and UEType 2 are configured with pcch-Config A}. In some embodiments, pcch-ConfigSpecificList[1] may correspond to {PLMN+CAG1 / in the network of PLMN+CAG, UEType 3 is configured with pcch-Config B}. In some embodiments, pcch-ConfigSpecificList[2] may correspond to {in the network of PLMN+CAG2: UEType1+UEtype2 are configured with pcch-Config C}.

[0096] 3. Monitor changes in system information

[0097] The following embodiments describe how the network and / or client monitors changes (e.g., changes, modifications, deviations, adjustments, etc.) in system information. In conventional schemes, the modification period is determined based on the paging cycle broadcast in the system information. For example, Figure 6 An example table illustrating SI change indication and public warning system (PWS) notification according to some embodiments of the present disclosure is shown.

[0098] However, different UE types and / or networks may configure different paging cycles. The modification period may also be different for different system information elements. Therefore, conventional solutions do not provide a mechanism for determining the modification period to take these real-world scenarios into account.

[0099] To solve this problem, the network should be allowed to configure different modification periods for different system information and / or different system information elements.

[0100] To achieve this, in some embodiments, a cell (e.g. Figure 1 BS102, Network, Figure 3 302 in the system information, etc.) can configure different modification periods for a portion of the system information (e.g., part, subset, segment, etc.). For example, a cell can configure UE type and / or network specific system information elements.

[0101] To achieve this, in some embodiments, the cell may include information in the paging / short message, where the information may indicate (eg, identify, define, etc.) which modification should and / or be adopted.

[0102] 3.1Configure modification period

[0103] Figure 7 An example table illustrating modification periods according to UE type, default paging cycle, and system information according to some embodiments of the present disclosure is shown.

[0104] In some embodiments, the UE type may include a network type. For example, the network type may be a cell access group (CAG), a standalone non-public network (SNPN), and / or a standalone PLMN.

[0105] In some embodiments, the UE type may include a network identifier (ID). For example, the network ID may be a PLMN, a tracking area code (TAC), a CAG ID, and / or a SNPN ID.

[0106] In some embodiments, the UE type may include an access category and / or an access class. In some embodiments, the UE type may include different beams and / or corresponding CSI-RS resources. In some embodiments, the UE type may include different slices.

[0107] In some embodiments, the modification period may be configured by different M values ​​with the same paging cycle, different cycles with the same M value, and / or different M values ​​and / or cycles.

[0108] In some embodiments, on the UE side, the UE may adopt one or more modification periods. In some embodiments, paging and / or short messages (DCI) may explicitly and / or implicitly indicate which modification period(s) should be and / or adopted. In some embodiments, implicit adoption may mean that the UE determines the modification period based on predefined criteria (e.g., UE type).

[0109] 3.2 Instruction modification period

[0110] In some embodiments, if the system information of UE type 1 changes, the network may indicate the modification period explicitly or implicitly in the paging message. Figure 8 An example table illustrating bits of a paging message according to some embodiments of the present disclosure is shown. In a paging message, there are four bits, starting from the leftmost bit, indicating four UE types. For example, bit 1 may correspond to UE type 1, bit 2 may correspond to UE type 2, bit 3 may correspond to UE type 3, and bit 4 may correspond to UE type 4.

[0111] In some embodiments, once a UE detects paging, only type 1 UEs will attempt to receive system information in the next modification period with system frame number (SFN) mod (M1*cycle1) = 0. For example, Figure 9 An example table illustrating bits of a paging message according to some embodiments of the present disclosure is shown.

[0112] In some embodiments, if the bits of Type 1 UE and "All UEs" are both set to 1, then for Type 1 UE, system information may be received in the next modification period of SFN mod (M1*cycle 1) = 0 and / or in another next modification period of SFN mod (M4*cycle 4). For example, Figure 10 An example table illustrating bits of a paging message according to some embodiments of the present disclosure is shown.

[0113] 4. Determine radio resource configuration for one or more device types

[0114] The following embodiments describe how a network and / or customer determines (e.g., identifies, selects, confirms, etc.) a radio resource configuration (e.g., eDRX / DRX) for one or more device types. In some embodiments, a public MNO deploying a PNI-NPN may collect (e.g., aggregate, store, retrieve, etc.) UE-related information according to customer requirements. In some embodiments, a customer may adjust (e.g., modify, configure, etc.) a configuration based on UE-related information (e.g., UE battery status). In some embodiments, a UE may log (e.g., store, record, etc.) its battery status in Minimization of Drive Test (MDT) data. In some embodiments, a customer may adjust a radio resource configuration (e.g., DRX / eDRX cycle) based on statistical results.

[0115] In some embodiments, the UE may have one or more thresholds (e.g., predetermined values, etc.) that define low, medium, and / or high battery states corresponding to the UE battery.
