Background Technology Technical Field

[0003] Various aspects of this disclosure relate to wireless communication, and more specifically to techniques for reaching user equipment located in a limited coverage area of ​​a wireless communication network.

[0004] Related technical descriptions

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, broadcasting, or other similar services. These wireless communication systems may employ multiple access technologies that enable communication with several users by sharing available wireless communication system resources.

[0006] Despite significant technological advancements in wireless communication systems over the years, challenges remain. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and receivers. Therefore, there is a continuous expectation for improving the technical performance of wireless communication systems, including, for example: improving communication speed and data carrying capacity; improving the efficiency of shared communication media; reducing the power used by transmitters and receivers during communication; improving the reliability of wireless communication; avoiding redundant transmission and / or reception and related processing; improving the coverage area of ​​wireless communication; increasing the number and types of devices that can access the wireless communication system; increasing the ability of different types of devices to communicate with each other; and increasing the number and types of available wireless communication media. Therefore, there is a need for further improvements to wireless communication systems to overcome the aforementioned technical challenges and other obstacles. Summary of the Invention

The method includes: receiving signaling to configure the UE using a first set of resources for monitoring paging messages and a second set of resources for monitoring pre-paging messages; monitoring the second set of resources for pre-paging messages if one or more conditions are met; and performing one or more actions in response to detecting a pre-paging message.

[0008] On the other hand, a method for wireless communication at a network entity is provided.

[0025] This disclosure provides apparatus, methods, processing systems, and computer-readable media for reaching user equipment located in a limited coverage area of ​​a wireless communication network, for example, using a physical channel dedicated to pre-paging a UE located in a deep coverage area of ​​a wireless communication network.

[0026] For a variety of reasons, a wireless communication network may need to page a UE located within the network. For example, a UE may be the target of a mobile-terminated (MT) phone call. However, if the UE cannot receive a sufficiently strong signal, it may not be able to detect a page from the network. The UE may not receive a strong enough signal because it is in a deep coverage area or because it is blocked by some other physical barrier. Therefore, sometimes the network may be unable to reach the UE.

[0027] Various aspects of this disclosure provide techniques to assist in paging a UE within deep coverage areas. For example, if the network cannot paging the UE initially using legacy methods (e.g., involving conventional paging channels), the network can pre-paging the UE via a physical channel. In various aspects of this disclosure, the UE can be configured to monitor legacy paging via a first channel and to monitor pre-paging via a second channel. The UE can select which channel to monitor based on whether it is located in the normal or deep coverage area of ​​the wireless communication network.

[0028] By configuring a second channel for the UE to receive a pre-paging signal from the network, the network may be able to alert the UE that it is attempting to deliver information to it, prompting the UE to move to a location within normal coverage. After moving to normal coverage, the network may be able to reach the UE using regular paging and deliver the information. Therefore, pre-paging technology allows the UE to be reached even outside normal coverage areas. Thus, aspects of this disclosure can help improve the coverage of wireless communication networks.

[0029] An introduction to wireless communication networks

[0030] The techniques and methods described herein can be used in a variety of wireless communication networks. While aspects may be described herein using terms commonly associated with 3G, 4G, and / or 5G wireless technologies, aspects of this disclosure are equally applicable to other communication systems and standards not explicitly mentioned herein.

[0031] Figure 1 An example of a wireless communication network 100 in which the aspects described herein can be implemented is depicted.

[0032] Generally, wireless communication network 100 includes various network entities (optionally, network elements or network nodes). Network entities are typically communication devices and / or communication functions performed by communication devices (e.g., user equipment (UE), base station (BS), components of the BS, servers, etc.). For example, various functions of the network and various devices associated with and interacting with the network can be considered network entities. Furthermore, wireless communication network 100 includes a terrestrial aspect, such as terrestrial network entities (e.g., BS 102), and a non-terrestrial aspect, such as satellite 140 and aircraft 145, which may include airborne network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., terrestrial BSs) and user equipment.

[0033] In the depicted example, wireless communication network 100 includes BS 102, UE 104 and one or more core networks (such as Evolved Packet Core (EPC) 160 and 5G Core (5GC) network 190) that interoperate to provide communication services over various communication links, including wired and wireless links.

[0034] Figure 1Various example UEs 104 are described, which may more generally include: cellular phones, smartphones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players, cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electricity meters, air pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, Internet of Things (IoT) devices, always-on (AON) devices, edge processing devices, or other similar devices. UE 104 may also be more generally referred to as mobile devices, wireless devices, wireless communication devices, stations, mobile stations, subscriber stations, mobile subscriber stations, mobile units, subscriber units, wireless units, remote units, remote devices, access terminals, mobile terminals, wireless terminals, remote terminals, mobile phones, and others.

[0035] BS 102 communicates wirelessly with UE 104 via communication link 120 (e.g., transmitting or receiving signals to or from UE 104). Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also known as reverse link) transmission from UE 104 to BS 102 and / or downlink (DL) (also known as forward link) transmission from BS 102 to UE 104. In various aspects, communication link 120 may utilize multiple-input multiple-output (MIMO) antenna technologies, including spatial multiplexing, beamforming, and / or transmit diversity.

[0036] BS 102 may typically include: NodeB, enhanced NodeB (eNB), next-generation enhanced NodeB (ng-eNB), next-generation NodeB (gNB or gNodeB), access point, transceiver base station, radio base station, radio transceiver, transceiver functionality, transmit / receive point, and / or others. Each BS in BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and in some cases may overlap (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, BS may provide communication coverage for macro cells (covering a relatively large geographic area), pico cells (covering a relatively small geographic area, such as a stadium), femtocells (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0037] Although BS 102 is described as a single communication device in various aspects, it can be implemented in various configurations. For example, to give a few examples, one or more components of the base station can be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station can be virtualized. More generally, a base station (e.g., BS 102) can include components located at a single physical location or components located at various physical locations. In examples where the base station includes components located at various physical locations, the various components can each perform functions, such that the various components collectively achieve functionality similar to a base station located at a single physical location. In some aspects, a base station including components located at various physical locations can be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0038] Different BSs 102 within the wireless communication network 100 can also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with EPC 160 via a first backhaul link 132 (e.g., S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) can interface with 5GC 190 via a second backhaul link 184. BSs 102 can communicate directly or indirectly (e.g., via EPC 160 or 5GC 190) on a third backhaul link 134 (e.g., X2 interface), which can be wired or wireless.

[0039] Wireless communication network 100 can subdivide the electromagnetic spectrum into various categories, bands, channels, or other characteristics. In some aspects, subdivision is provided based on wavelength and frequency, where frequency may also be referred to as carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410MHz-7125MHz, which is often (interchangeably) referred to as “sub-6GHz”. Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250MHz to 71,000MHz, which is sometimes (interchangeably) referred to as “millimeter wave” (“mmW” or “mmWave”). In some cases, FR2 can be further defined according to subranges (such as a first subrange FR2-1 including 24,250MHz-52,600MHz and a second subrange FR2-2 including 52,600MHz-71,000MHz). Base stations configured to communicate using mmWave / near mmWave radio bands (e.g., mmWave base stations such as BS 180) can utilize beamforming (e.g., 182) with UEs (e.g., 104) to improve path loss and range.

[0040] The communication link 120 between BS 102 and, for example, UE 104 can be via one or more carriers, which may have different bandwidths (e.g., 5MHz, 10MHz, 15MHz, 20MHz, 100MHz, 400MHz and / or other MHz) and may be aggregated in various ways. The carriers may be adjacent to each other or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated to DL compared to UL).

[0041] Compared to lower-frequency communication, communication using higher frequency bands may have higher path loss and shorter range. Therefore, some base stations (e.g., Figure 1The beamforming 182 of the BS 180 (180) with the UE 104 can be used to improve path loss and range. For example, the BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, the BS 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182''. The UE 104 may receive beamformed signals from the BS 180 in one or more receive directions 182''. The UE 104 may also transmit beamformed signals to the BS 180 in one or more transmit directions 182''. The BS 180 may also receive beamformed signals from the UE 104 in one or more receive directions 182''. The BS 180 and UE 104 may then perform beamforming training to determine the optimal receive and transmit directions for each of the BS 180 and UE 104. It is worth noting that the transmit and receive directions of the BS 180 may be the same or different. Similarly, the sending and receiving directions of UE 104 can be the same or different.

[0042] The wireless communication network 100 further includes a Wi-Fi AP 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, unlicensed spectrum in 2.4 GHz and / or 5 GHz.

[0043] Some UEs 104 may use device-to-device (D2D) communication links 158 to communicate with each other. The D2D communication link 158 may use one or more sidelink channels, such as physical sidelink broadcast channel (PSBCH), physical sidelink discovery channel (PSDCH), physical sidelink shared channel (PSSCH), physical sidelink control channel (PSCCH), and / or physical sidelink feedback channel (PSFCH).

[0044] EPC 160 may include various functional components, including: Mobility Management Entity (MME) 162, other MMEs 164, Serving Gateway 166, Multimedia Broadcast Multicast Service (MBMS) Gateway 168, Broadcast Multicast Service Center (BM-SC) 170, and / or Packet Data Network (PDN) Gateway 172, as in the illustrated example. MME 162 may communicate with Home Subscriber Server (HSS) 174. MME 162 is the control node that handles signaling between UE 104 and EPC 160. Generally, MME 162 provides bearer and connectivity management.

[0045] Generally, user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which is itself connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP services 176, which may include, for example, the Internet, intranets, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services.

[0046] The BM-SC 170 provides functionality for MBMS user service dispatch and delivery. The BM-SC 170 can serve as an entry point for content provider MBMS transmissions, can be used to authorize and initiate MBMS bearer services within a Public Land Mobile Network (PLMN), and / or can be used to schedule MBMS transmissions. The MBMS gateway 168 can be used to distribute MBMS services to BS 102 belonging to a Broadcast-Specific Service Single Frequency Network (MBSFN) area, and / or can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0047] 5GC 190 may include various functional components, including: Access and Mobility Management Function (AMF) 192, other AMFs 193, Session Management Function (SMF) 194, and User Plane Function (UPF) 195. AMF 192 can communicate with Unified Data Management (UDM) 196.

[0048] AMF 192 is the control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides services such as Quality of Service (QoS) flow and session management.

[0049] Internet Protocol (IP) packets are transmitted via UPF 195, which connects to IP service 197 and provides the UE with IP address allocation and other functions for 5GC 190. IP service 197 may include, for example, the Internet, intranet, IMS, PS streaming service, and / or other IP services.

[0050] In various aspects, to give a few examples, network entities or network nodes can be implemented as aggregated base stations, decomposed base stations, components of base stations, integrated access and backhaul (IAB) nodes, relay nodes, and sidelink nodes.

[0051] Figure 2An example decomposed base station 200 architecture is depicted. The decomposed base station 200 architecture may include one or more central units (CUs) 210, which may communicate directly with the core network 220 via a backhaul link, or indirectly with the core network 220 through one or more decomposed 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. CUs 210 may communicate with one or more distributed units (DUs) 230 via corresponding midhaul links (such as F1 interfaces). DUs 230 may communicate with one or more radio units (RUs) 240 via corresponding fronthaul links. RUs 240 may communicate with a corresponding UE 104 via one or more radio frequency (RF) access links. In some specific implementations, UE 104 may be served simultaneously by multiple RUs 240.

[0052] Each unit in a cell (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO frame 205) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cell, or an associated processor or controller providing instructions to the unit's communication interface, may be configured to communicate with one or more other units via transmission media. For example, these units may include wired interfaces configured to receive signals or transmit signals to one or more other units via wired transmission media. Additionally or alternatively, a unit may include a wireless interface that may include a receiver, transmitter, or transceiver (such as a radio frequency (RF) transceiver) configured to receive signals on a wireless transmission medium or transmit signals to one or more other units, or both.

[0053] In some aspects, CU 210 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Serving Data Adaptation Protocol (SDAP), etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by CU 210. CU 210 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or combinations thereof. In some implementations, CU 210 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, CU-UP units can communicate bidirectionally with CU-CP units via an interface such as an E1 interface. CU 210 can be implemented to communicate with DU 230 for network control and signaling, as needed.

[0054] DU 230 may correspond to a logic unit that includes one or more base station functions for controlling the operation of one or more RU 240s. In some aspects, DU 230 may host one or more of the Radio Link Control (RLC) layer, Media 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, etc.) at least in part, according to functional splits (such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signaling with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0055] Lower-layer functionality can be implemented by one or more RU 240s. In some deployments, an RU240 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 both, based at least in part on functional decomposition (such as lower-layer functional decomposition). In such architectures, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UE 104s. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration enables the implementation of the DU 230 and CU 210 in cloud-based RAN architectures (such as vRAN architectures).

[0056] SMO framework 205 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, SMO framework 205 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, SMO framework 205 can be configured to interact with a cloud computing platform such as Open Cloud (O-Cloud) 290 to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface such as the O2 interface. Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some implementations, SMO framework 205 can communicate with hardware aspects of the 4G RAN, such as Open eNB (O-eNB) 211, via the O1 interface. Additionally, in some implementations, SMO framework 205 can communicate directly with one or more RU 240s via the O1 interface. SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of SMO framework 205.

[0057] The non-RT RIC 215 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 225. The non-RT RIC 215 can be coupled to or communicate with the near-RT RIC 225, such as via an A1 interface. The near-RT RIC 225 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface such as an E2 interface, connecting one or more CU 210s, one or more DU 230s, or both, and O-eNBs to the near-RT RIC 225.

[0058] 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 an external server. This information can be utilized by the near-RT RIC 225 and may be received from non-network data sources or network functions at the SMO framework 205 or the non-RT RIC 215. 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 of performance and employ AI / ML models to perform corrective actions via the SMO framework 205 (such as reconfiguration via O1) or by creating RAN management policies (such as A1 policies).

[0059] Figure 3 Various aspects of examples BS 102 and UE 104 are described.

[0060] Generally, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively referred to as 334), transceivers 332a-332t (collectively referred to as 332) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., data source 312) and the wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement the various functions described herein related to wireless communication.

[0061] Generally, UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively referred to as 352), transceivers 354a-354r (collectively referred to as 354) including modulators and demodulators, and other aspects that enable the wireless transmission of data (e.g., retrieved from data source 362) and the wireless reception of data (e.g., provided to data sink 360). UE 104 includes a controller / processor 380 that can be configured to implement the various functions described herein related to wireless communication.

[0062] Regarding example downlink transmission, BS 102 includes a transmission processor 320 that can receive data from data source 312 and control information from controller / processor 340. The control information may be for a Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical HARQ Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Group Shared PDCCH (GC PDCCH), and / or others. In some examples, this data may be for a Physical Downlink Shared Channel (PDSCH).

[0063] The transmitter processor 320 can process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmitter processor 320 can also generate reference symbols (such as those for the primary synchronization signal (PSS), secondary synchronization signal (SSS), PBCH demodulation reference signal (DMRS), and channel state information reference signal (CSI-RS)).

[0064] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols where applicable, and can provide the output symbol stream to the modulators (MODs) in transceivers 332a-332t. Each modulator in transceivers 332a-332t can process its corresponding output symbol stream to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signal from the modulators in transceivers 332a-332t can be transmitted via antennas 334a-334t respectively.

[0065] To receive downlink transmissions, UE 104 includes antennas 352a-352r that receive downlink signals from BS 102 and provide the received signals to demodulators (DEMODs) in transceivers 354a-354r respectively. Each demodulator in transceivers 354a-354r can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator can further process the input sample to obtain the received symbols.

[0066] The MIMO detector 356 acquires received symbols from all demodulators in transceivers 354a-354r, performs MIMO detection on the received symbols where applicable, and provides the detected symbols. The receive processor 358 processes (e.g., demodulates, deinterleaves, and decodes) the detected symbols, provides the decoded data for UE 104 to data sink 360, and provides the decoded control information to controller / processor 380.

[0067] Regarding the example uplink transmission, UE 104 further includes a transmission processor 364 that receives and processes data from data source 362 (e.g., for PUSCH) and control information from controller / processor 380 (e.g., for Physical Uplink Control Channel (PUCCH)). Transmission processor 364 can also generate reference symbols for reference signals (e.g., for Sounding Reference Signal (SRS)). Symbols from transmission processor 364 may be pre-decoded by TX MIMO processor 366, where applicable, further processed by modulators in transceivers 354a-354r (e.g., for SC-FDM), and transmitted to BS 102.

[0068] At BS 102, uplink signals from UE 104 can be received by antennas 334a-334t, processed by demodulators in transceivers 332a-332t, detected by MIMO detector 336 where applicable, and further processed by receiver processor 338 to obtain decoded data and control information transmitted by UE 104. Receiver processor 338 can provide the decoded data to data sink 339 and the decoded control information to controller / processor 340.

[0069] Memory 342 and memory 382 can store data and program code for BS 102 and UE 104, respectively.

[0070] Scheduler 344 can schedule UE to transmit data on the downlink and / or uplink.

[0071] In various respects, BS 102 can be described as transmitting and receiving various types of data associated with the methods described herein.

Similarly, "receiving" can refer to various mechanisms that acquire data, such as from antenna 334a-334t, transceiver 332a-332t, RX MIMO detector 336, controller / processor 340, receive processor 338, scheduler 344, memory 342, and / or other aspects described herein.

[0072] In various respects, UE 104 can also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, “transmitting” can refer to various mechanisms that output data, such as from data source 362, memory 382, ​​transmit processor 364, controller / processor 380, TX MIMO processor 366, transceiver 354a-354t, antenna 352a-352t, and / or other aspects described herein.

[0073] In some respects, the processor can be configured to perform various operations (such as those associated with the methods described herein) and to send (output) data to or receive data from another interface configured to send or receive data, respectively.

[0074] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes the use of wireless communication networks (such as Figure 1 All aspects of the data structure of the wireless communication network 100.

[0075] Specifically, Figure 4A Figure 400 is an example of the first subframe within a 5G (e.g., 5G NR) frame structure. Figure 4B Figure 430 illustrates an example of a DL channel within a 5G subframe. Figure 4C Figure 450 illustrates an example of the second subframe within a 5G frame structure, and Figure 4D Figure 480 illustrates an example of a UL channel within a 5G subframe.

[0076] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single-Carrier Frequency Division Multiplexing (SC-FDM) will (e.g., as...) Figure 4B and Figure 4D The system bandwidth (as depicted in the text) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0077] Wireless communication frame structures can be frequency division duplex (FDD), where for a specific set of subcarriers, subframes within that set are dedicated to either deep (DL) or ultra-low (UL). Wireless communication frame structures can also be time division duplex (TDD), where for a specific set of subcarriers, subframes within that set are dedicated to both DL and UL.

[0078] exist Figure 4A and Figure 4C In this example, the wireless communication frame structure is TDD, where D stands for DL, U for UL, and X is flexibly used between DL and UL. The UE can be configured using the time slot format via the received Time Slot Format Indicator (SFI) (dynamically via DL Control Information (DCI) or semi-statically / statically via Radio Resource Control (RRC) signaling). In the depicted example, a 10ms frame is divided into 10 equal-sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. Subframes may also include micro-slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0079] In some respects, the number of time slots within a subframe is based on the time slot configuration and parameter set. For example, for time slot configuration 0, different parameter sets (μ) 0 to 6 allow 1, 2, 4, 8, 16, 32, and 64 time slots per subframe, respectively. For time slot configuration 1, different parameter sets 0 to 2 allow 2, 4, and 8 time slots per subframe, respectively. Therefore, for time slot configuration 0 and parameter set μ, there are 14 symbols per time slot and 2µ time slots per subframe. The subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to... kHz, where μ is the parameter set from 0 to 6. Therefore, the parameter set... It has a subcarrier spacing of 15 kHz and a parameter set It has a subcarrier spacing of 960 kHz. The symbol length / duration is negatively correlated with the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D It provides slot configuration 0 with 14 symbols per slot and parameter set with 4 slots per subframe. Example: The time slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0080] like Figure 4A , Figure 4B , Figure 4C and Figure 4DAs depicted, the resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also known as a physical RB (PRB)) extending for, 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.

[0081] like Figure 4A As illustrated in the example, some REs in the RE carry information for the UE (e.g., Figure 1 and Figure 3 The reference (pilot) signal (RS) for the UE (104) may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0082] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries the DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0083] The Primary Synchronization Signal (PSS) can be located within symbol 2 of a specific subframe of the frame. The PSS is generated by the UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identifier.

[0084] The secondary synchronization signal (SSS) can be located in symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identifier group number and radio frame timing.

[0085] Based on the Physical Layer Identifier and Physical Layer Cell Identifier Group Number, the UE can determine the Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The Physical Broadcast Channel (PBCH), carrying the Master Information Block (MIB), can be logically grouped with the PSS and SSS to form a Synchronization Signal (SS) / PBCH block. The MIB provides the System Frame Number (SFN) and the number of Restricted Frames (RBs) in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information (such as System Information Blocks (SIBs)) not transmitted via the PBCH, and / or paging messages.

[0086] like Figure 4CAs illustrated, some REs in the REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are possible). The UE can transmit DMRS for PUCCH and DMRS for PUSCH. PUSCH DMRS can be transmitted, for example, in the first or second symbol before the PUSCH. PUCCH DMRS can be transmitted in different configurations depending on whether a short or long PUCCH is being transmitted and depending on the specific PUCCH format used. UE104 can transmit a Sounding Reference Signal (SRS). SRS can be transmitted, for example, in the last symbol of a subframe. SRS can have a comb structure, and the UE can transmit SRS on one of the comb teeth. SRS can be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0087] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH can be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), pre-decoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSR), power clearance reports (PHR), and / or UCI.

[0088] Non-terrestrial network overview

[0089] Satellite-based NTN can play a critical role in providing global connectivity, including in rural and coastal areas, which is essential for supporting important use cases. NTN generally refers to a network or network segment that uses RF resources on a satellite. NTN signaling can be regenerative (with onboard NTN processing) or transparent (e.g., where the satellite transmits its received content back to Earth only with amplification and a shift from uplink to downlink frequencies).

[0090] Figure 5A An example of a wireless communication network 500a including NTN entity 140 is illustrated. In some examples, wireless communication network 500a may implement aspects of wireless communication network 100. For example, wireless communication network 500a may include ground stations (such as BS 102), UE 104, and NTN entities (such as satellite 140). In the case of a terrestrial network, BS 102 may serve a coverage area or cell 110a, and in the case of a non-terrestrial network, NTN entity 140 may serve a coverage area 110b. Some NTNs may employ airborne platforms (e.g., drones or balloons) and / or spaceborne platforms (e.g., satellites).

[0091] In some respects, coverage area 110a can be considered the “normal coverage” area of ​​UE 104. That is, UE 104 is expected to receive at least a minimum level of reception and have at least a minimum level of reception quality from wireless communication network 500a. In some cases, the network can be configured to define a threshold for this minimum level, enabling the UE to decode system information (SI) (called synchronization signal block (SSB)) included in the reference signal.

[0092] Coverage area 110b can be considered the extended coverage area of ​​UE 104, and is sometimes referred to herein as the deep coverage area. Within the extended coverage area, UE 104 is expected to receive at least a minimum level of reception, a threshold lower than that of the normal coverage area. Similarly, UE 104 is expected to have at least a minimum level of reception quality from wireless communication network 500a, but a threshold lower than that of normal coverage. In this way, within the extended coverage area, UE 104 will have a degraded level of reception and quality compared to the normal coverage area. For example, within the extended coverage area, the UE may expect to detect an SSB, but may not expect to decode the SI from the SSB. Outside coverage area 110b, UE 104 may not receive any signal from wireless communication network 500a.

[0093] NTN entity 140 can communicate with BS 102 and UE 104 as part of wireless communication within the NTN. In the case of a terrestrial network, UE 104 can communicate with BS 102 via communication link 514. In the case of NTN wireless communication, NTN entity 140 can be the serving cell for UE 104 via communication link 516, referred to as the serving link. In some respects, NTN entity 140 can act as a repeater (or remote radio head) for BS 102 and UE 104. For example, BS 102 can communicate with NTN entity 140 via communication link 518, and NTN entity 140 can relay signaling between BS 102 and UE 104 via communication links 516 and 518. NTN entity 140 can communicate with a terrestrial gateway (e.g., a disc-shaped satellite dish) via a feeder link. BS 102 can be co-located with the gateway, deployed behind the gateway, and / or deployed on satellite 140.

[0094] For LEO satellites, the NTN beam can cover an area of ​​100km to 1000km, while for geostationary orbit (GEO) satellites, the NTN beam can cover an area of ​​200km to 3500km. Figure 5BAs illustrated, an NG-RAN 500b deployment may include a satellite 140 and an NTN gateway (GW) 505 acting as a cellular Uu link between the UE 104 and the terrestrial network (TN) gNB 102 (and the 5G core network 190). NG-RAN 500b generally refers to a radio access network for 5G that provides both NR and LTE radio access. The link between the UE 104 and the satellite 140 is typically referred to as a serving link, while the link between the satellite and the GW is typically referred to as a feeder link.

[0095] In some respects, as satellite 140 moves across its orbit, it communicates with different UEs. As the satellite orbits, it communicates with different UEs via different beams. The uplink signal from the UE experiences a round-trip delay (RTD), which is typically the sum of the delay on the serving link and the delay on the feeder link. The maximum RTD is typically approximately 541.46 ms for GEO satellites, 25.77 ms for LEO satellites at an altitude of 600 km, and 41.77 ms for LEO satellites at an altitude of 1200 km. Compared to the speed of LEO satellites, the speed of the UE is generally negligible.

[0096] When satellite 140 moves and UE 104 is outside the coverage area 110b of satellite 140, it is called discontinuous coverage. Furthermore, when satellite 140 may not have a feeder link connection to the ground station, it is called intermittent coverage.

[0097] Various aspects related to paging in deep coverage scenarios

[0098] Various aspects of this disclosure relate to techniques for paging user equipment located in a limited (depth) coverage area of ​​a wireless communication network (such as wireless communication network 500a of Figure 5).

[0099] As mentioned above, wireless communication networks may page UE devices for a variety of reasons. Figure 6 In one example illustrated, the core network has downlink data to be delivered to the UE (e.g., incoming calls to the UE).

[0100] In a conventional network, if a UE has transitioned to an idle state, the network may not be able to locate the UE to directly signal this idle state. Therefore, the core network may send a paging request to a set of RAN nodes belonging to the same tracking area as the UE. Each RAN node forwards the paging message via a physical channel (defined by a set of time and frequency resources). If the UE is able to decode the paging message, it responds, performs service registration, and then transitions back to the RRC connected state. The UE can then connect to the core network, and the complete sequence for establishing a call or data session may begin. Therefore, paging messages are typically used by the network to reach UEs in idle mode.

[0101] In some networks (such as NTN networks), the uplink link budget may be small, which can lead to paging channel instability. For mobile-initiated (MO) calls or sessions, it is generally expected that users move to a preferred location or attempt to minimize congestion to improve channel reception.

[0102] However, for mobile termination (MT) calls or sessions, the uplink channel may be so weak that the network will not receive a response from the UE to a paging message from the RAN. In other words, the UE may be located in a deep coverage area, so the link will not function properly, and the UE may not receive downlink paging messages from the RAN, or even if the UE does receive a paging message, the network may not receive a response from the UE.

[0103] In some examples, the UE may not receive paging messages (because the UE is located in a deep coverage area geographically far from the base station). In other examples, the UE may not receive paging messages because the UE is obstructed, such as being in a pocket, backpack, or other physical barrier that prevents the signal from passing through.

[0104] Figure 6 A sample call flowchart 600 depicts a wireless communication network using a conventional paging procedure to page a UE. Figure 6 In example call flow 600, the UPF (User Plane Function) of the core network receives downlink data for the UE. The UPF then sends a data notification containing the downlink data for the UE to the SMF (Session Management Function). The SMF then sends an acknowledgment of the data notification back to the UPF. Upon receiving this acknowledgment, the UPF sends the downlink data to the SMF.

[0105] The SMF also sends a message to the AMF (Access and Mobility Management Function) of the core network, which in turn sends a response back to the SMF. A session is then initiated, and the AMF requests paging from the RAN. As illustrated, a timer can be started when the AMF sends a paging request to the RAN to effectively set a time limit for the paging process. The time limit can be set to provide sufficient time for message exchange between the RAN and the UE, while limiting the time spent if the UE is unreachable.

[0106] If the UE is located within the RAN's normal coverage area, the RAN will be able to successfully page the UE and establish an RRC connection before the timer expires. However, if the UE is located in the RAN's extended coverage area or no coverage area, the RAN may not be able to successfully reach the UE via its paging message, or may not be able to receive the UE message transmitted in response to the paging message. Call flow 600 describes an example use case where the UE cannot receive the paging message from the RAN and therefore cannot complete the RRC connection establishment (as indicated by X via the paging-related message).

[0107] Various aspects related to UE pre-paging

[0108] This disclosure provides a technique that helps a network reach a UE located in an extended coverage area (sometimes referred to herein as a limited or deep coverage area). Due to limited coverage, the network may not be able to reach the UE via normal paging.

[0109] As discussed in this paper, a UE may be located within an extended coverage area due to physical distance from the base station or some other physical obstruction. In some respects, RANs that cannot page UEs using typical techniques can alternatively implement pre-paging techniques to reach the UE via the same or different radio channels in the wireless communication network. The pre-paging technique proposed in this paper is particularly useful for NTN networks.

[0110] In some aspects, the wireless communication network can signal the pre-paging configuration to the UE. This pre-paging configuration can instruct the UE to monitor and detect the set of time and frequency resources for pre-paging messages. To reduce the chance of false alarms, the pre-paging resources utilized by the wireless communication network can be orthogonalized in the time-frequency code domain. For example, to ensure that only one UE, and not other UEs, decodes the pre-paging resources allocated to it, different sets of resources can be assigned to different UEs.

[0111] Figure 7 A sample call flowchart 700 is depicted for a UE pre-paged by a wireless communication network. In some respects, Figure 7 (and / or Figure 8 The UE shown in the diagram can be about Figure 1 and Figure 3An example of UE 104 depicted and described. In some respects, Figure 7 (and / or Figure 8 The network entity (RAN) shown in the diagram can be about Figure 1 and Figure 3 The BS 102 (e.g., gNB) depicted and described or about Figure 2 An example of a decomposed base station that is depicted and described.

[0112] At 702 of the example call flowchart 700, the RAN sends a pre-paging configuration to the UE. This pre-paging configuration can indicate the details that effectively define the pre-paging channel. For example, the pre-paging configuration can indicate the time and frequency resources that the UE can monitor for pre-paging when it is within limited coverage. In some cases, the UE can determine that it is in a limited (depth / extension) coverage area based on a threshold of signal strength or quality. Such thresholds can be indicated as part of the pre-paging configuration.

[0113] In some respects, the pre-paging configuration can be broadcast by the RAN as system information (SI) to the entire cell. Alternatively, the pre-paging configuration can be broadcast by the RAN as part of the basic system information in an SIB-1 message. Or, the pre-paging configuration can be broadcast via a new SIB message. Generally, the UE can receive the pre-paging configuration when it is within the normal coverage area of ​​the wireless communication network (where the signal strength is sufficient for SIB decoding).

[0114] In this example, the pre-paging search space is cell-specific and configured as a common search space, thus utilizing the same time and frequency resources for pre-paging. In this context, the search space may refer to a set of pre-paging decoding candidates that the UE can monitor (e.g., where each candidate is defined by a set of time and frequency resources). Each UE in the cell can have a distinct identifier assigned to it, and this identifier can be used in subsequent pre-paging messages, so that even if configuration information is broadcast to all UEs in the cell, only the intended UE receiving the pre-paging message is allowed to detect and decode the message.

[0115] Since the pre-paging configuration is broadcast to all UEs in the cell, code domain orthogonality can be used to separate UE-specific resources from common resources. In some respects, this is done via the RNTI (Radio Network Temporary Identifier) ​​used to monitor the pre-paging PDCCH (Physical Downlink Control Channel). That is, each UE monitors the control channel to obtain a UE-specific unique code or RNTI (e.g., with a checksum scrambled with that unique code or RNTI).

[0116] At 704 of example call flowchart 700, the UE moves to a deep coverage area of ​​the wireless communication network. As mentioned above, in a deep coverage area, the UE may not be able to reach you via regular paging, although the RAN may attempt a regular paging procedure before attempting a pre-paging, because the RAN may not know that the UE is within deep coverage.

[0117] At 706, the RAN receives a paging request from the core network. The RAN starts a timer at 708 and attempts to page the UE via the legacy paging method at 710. Because the UE is in a deep coverage area, it cannot receive the legacy paging method, and the paging fails (as indicated by X).

[0118] Therefore, at 712, the timer expires, and at 714, the RAN sends a pre-paging message to the UE via the pre-paging physical channel. Since the UE was previously configured using resources for monitoring pre-paging messages, the UE is able to receive the pre-paging message from the RAN.

[0119] At point 716, the UE can perform one or more actions after detecting a pre-paging message. For example, the UE can alert the user to a message or call via any mechanism such as vibration, ringing, or pop-up notification. Upon receiving this alert, the user can move the UE to a better location so that the UE can connect to the network and receive messages. In some cases, the user moves the UE to the normal coverage area of ​​the wireless communication network.

[0120] At point 718, the RAN may perform one or more actions after sending the pre-paging message. For example, the RAN may wait for the expected MO session. In another example, the RAN may wait for a predetermined period of time and then repeat the legacy paging message if no response is received from the UE. In yet another example, the RAN may wait for a predetermined period of time and then repeat the pre-paging message if no response is received from the UE.

[0121] Although Figure 7 While not explicitly described, in some cases, a UE can signal to the RAN that it has the capability to receive pre-paging messages. UE capabilities can be determined by hardware requirements or pre-paging features that the user can enable or disable on the UE. In some aspects, a UE's pre-paging capability can be disabled when it enters power-saving mode. Based on the capability information, the network can identify a subset of UEs existing in the cell as candidates for pre-paging and assign unique codes or RNTIs only to these subsets of UEs in the cell.

[0122] In some aspects, capability signaling can be sent to the RAN before the RAN signals the pre-paging configuration. In other aspects, capability signaling can be sent to the RAN after the RAN signals the pre-paging configuration. In either scenario, the network can assign a temporary RNTI to monitor the PDCCH at any stage during which the UE is in RRC connected state. Furthermore, a dedicated DCI (Downlink Control Information) format can be reserved by the wireless communication network for pre-paging. In some aspects, the DCI is scrambled by the RNTI.

[0123] In another aspect, the network can assign a validity timer to each RNTI and delete the RNTI after the validity timer expires. In this way, the RNTI is reserved only for a predetermined period of time, and if the first UE enters idle mode, the RNTI can be reused for a second UE.

[0124] In other aspects where time and frequency resources are group-shared, UEs within a cell can be divided into multiple groups. The RAN can broadcast group identifiers and unique RNTI codes to the cell. In this technique, there are two levels of organization: RNTI and group identifier. In this way, each group has its own time and frequency resources, and within each group, the time and frequency resources for each UE are also separate.

[0125] In some cases, as an alternative to broadcast pre-paging configuration, the UE may request pre-paging configuration. Figure 8 Another example call flowchart 800 depicts a UE requesting pre-paging configuration.

[0126] At 802 in example call flowchart 800, the UE establishes an RRC connection to the RAN of the wireless communication network when it is within the normal coverage area of ​​the wireless communication network. At 804, the UE requests pre-paging configuration information from the RAN. This request can be delivered in any suitable type of signaling (e.g., via UCI or MAC CE). At 806, the RAN sends the pre-paging configuration information. This pre-paging configuration information can be sent in any suitable UE-specific signaling.

[0127] Therefore, since the UE is in RRC connected mode, dedicated time and frequency resources for pre-paging can be used to configure a UE-specific pre-paging search space. Thus, the network can provide the UE with a UE-specific pre-paging configuration, or a UE-specific pre-paging search space. Because it is UE-specific, the network orthogonals the UE in time and frequency. As illustrated, in some cases, the pre-paging configuration can be delivered in the RRC release message.

[0128] Although Figure 8While not explicitly described, the UE can also signal to the RAN the capability to accept pre-paging. In some respects, capability signaling can be sent to the RAN before, simultaneously with, or after requesting pre-paging configuration from the RAN.

[0129] Later, at 808, the UE transitions to RRC idle mode. Subsequently, at 810, the UE moves to a deep coverage area of ​​the wireless communication network. When the UE is in a deep coverage area, the RAN receives a paging (or pre-paging) request from the core network and performs the actions described above. Figure 7 The same actions being discussed.

[0130] As discussed above, in Figure 8 In the example call flowchart 800, the pre-paging configuration is UE-specific (while... Figure 7 In example call flowchart 700, the pre-paging configuration is cell-specific. For call flowchart 800, when the UE is in RRC connected mode, the RAN provides the pre-paging configuration to the UE, and then when the UE transitions to idle mode, the RAN releases the UE.

[0131] When in idle mode, the UE can perform cell reselection as it attempts to camp on a cell with the best signal quality and strength. However, if the UE camps on a different cell than the one from which it received the pre-paging configuration, the previous pre-paging configuration will be invalid for the UE. This can happen if the UE moves at high speed after entering a deep coverage area. Furthermore, in the case of NTN networks, even if the UE itself is static, it can reselect to a different satellite or a different beam of the same satellite in idle mode.

[0132] To address this issue, this disclosure provides a technique for configuring a UE to pre-paging in any cell within a cell group. When the RAN sends pre-paging configuration information at 806 of the example call flowchart 800, the RAN may indicate a list of objects in the pre-paging configuration message, which may be indexed by a cell ID. Each object may have a set of parameters for the UE to monitor pre-paging channels in that particular cell.

[0133] In some cases, the RAN can predict how many cell IDs are needed to configure the UE, and provide this information to the UE in the pre-paging configuration. In this way, even if the UE reselects a different cell in the future, the UE can continue to be configured for pre-paging because a part of the pre-paging configuration (e.g., a code such as RNTI or group ID + RNTI) is valid across multiple cells.

[0134] In some respects, RAN nodes can exchange codes via an interface (e.g., the XNAP interface), so each cell in these cells has the same configuration information. In other respects, RAN nodes in the same tracking area can maintain a common resource pool from which unique codes are assigned to the corresponding UE when the UE is released from an RRC connection with a cell. In this way, a code pool (such as RNTI) can be valid across multiple RAN nodes in the same tracking area, ensuring that the pre-paging configuration generated by the RAN nodes is valid across these multiple cells.

[0135] When a RAN node provides pre-paging configuration to a UE, it provides the UE with multiple time-frequency resources valid across multiple cells. Therefore, even if the UE reselects a different cell while in idle mode, it can continue monitoring for pre-paging using the same code. This code can also be associated with a validity timer. When the timer expires, the code can be released, and the UE may need to be reconfigured to monitor for pre-paging messages.

[0136] Figure 9 Example chart 900 depicts signal strength / quality thresholds for different coverage areas of a wireless communication network, which can be effectively defined.

[0137] According to 902 of Figure 900, when the UE is able to receive the lowest level of signal (by variable Q) rxlevmin (represented by) and / or receiving the lowest quality signal (as indicated by the variable Q) qualmin When (indicated by the signal), the UE can be considered to be within the normal coverage area of ​​the wireless communication network. According to 904 of Figure 900, when the UE can only receive the lowest level of signal Q... rxlevmin_CE And / or only able to receive the lowest quality signal Q qualmin_CE If the conditions are met, the UE can be considered to be in a deep coverage area of ​​the wireless communication network. In some implementations, the RAN can indicate these sets of parameters to the UE via system information messages (such as SIB-1). If none of these sets of parameters are met, the UE can be considered to be in an area without coverage.

[0138] If no cell meets the following conditions, the UE can be classified as being in a deep coverage area: Received signal level S rxlev Greater than Q rxlevmin And the received signal quality S qual Greater than Q qualmin In addition, there exists at least one cell in which the received signal level S rxlev Greater than Q rxlevmin_CE And the received signal quality S qual Greater than Q qualmin_CEIf these parameters are met, the UE can detect the SSB (Synchronization Signal Block), but cannot decode the SIB (System Information Block) from the RAN.

[0139] In all aspects of this disclosure, the UE uses parameters from Figure 900 to determine which coverage area it is in and monitors the appropriate channel. That is, if the UE determines that it is in a normal coverage area, it can monitor a first channel for legacy paging messages. However, if the UE determines that it is in a deep coverage area, it can monitor a second channel search space for pre-paging messages.

[0140] If a UE determines that it is in a deep coverage area and has pre-paging configurations for more than one cell, the UE can create a list of cell IDs and determine the intersection between the detected cells and the cell IDs for which the UE has pre-paging configurations. The UE can prioritize the cell IDs used for pre-paging monitoring in a predefined manner (e.g., best cell priority within the frequency range, explicit priority order configured by the network) or through other mechanisms.

26. The apparatus of claim 21, wherein the second set of resources is used to configure the signaling indication of the UE to be valid for pre-paging configuration on multiple cells.

27. The apparatus of claim 26, wherein one or more of the plurality of cells comprise non-terrestrial network (NTN) cells.

28. The apparatus of claim 16, wherein the one or more processors are further configured to execute the computer-executable instructions and cause the network entity to send signaling that configures the UE using different thresholds, the different thresholds indicating whether the UE is within extended coverage or normal coverage in the cell.

29. A method for conducting wireless communication at a user equipment (UE), the method comprising: The UE is configured by receiving signaling that utilizes a first set of resources for monitoring paging messages and a second set of resources for monitoring pre-paging messages. If one or more conditions are met, then the second set of pre-paging message monitoring resources is considered; as well as Perform one or more actions in response to the detection of a pre-paging message.

30. A method for conducting wireless communication at a network entity, the method comprising: If one or more conditions are met, a pre-paging message is sent to the user equipment (UE) on a second set of resources, wherein the second set of resources is different from the first set of resources used to send a paging message to the UE; as well as One or more actions are performed after the pre-paging message is sent.
