Description

Technical Field

[0001] This disclosure generally relates to wireless communication systems (or mobile communication systems). More specifically, this disclosure relates to bundling paging timing in wireless communication systems (or mobile communication systems). Background Technology

[0002] 5G mobile communication technology defines a wide frequency band, enabling high transmission rates and new services. It can be implemented not only in "sub-6GHz" bands such as 3.5GHz, but also in "above 6GHz" bands, including 28GHz and 39GHz, known as millimeter waves (mmWave). Furthermore, 6G mobile communication technology (referred to as "super 5G systems") is being considered in terahertz (THz) bands (e.g., the 95GHz to 3THz band) to achieve transmission rates fifty times faster than 5G and ultra-low latency one-tenth that of 5G.

[0003] At the outset of 5G mobile communication technology development, standardization was underway for the following items to support services and meet performance requirements associated with enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC): beamforming and massive MIMO for mitigating radio wave path loss and increasing radio wave transmission distance in millimeter waves; parameter sets supporting dynamic operation (e.g., operating multiple subcarrier spacings) for efficient utilization of millimeter wave resources and time slot formats; initial access technologies to support multi-beam transmission and broadband; the definition and operation of BWP (bandwidth portion); new channel coding methods such as LDPC (low-density parity-check) codes for large-volume data transmission and polar codes for highly reliable transmission of control information; L2 preprocessing; and network slicing for providing dedicated networks tailored to specific services.

[0004] Currently, given the services that 5G mobile communication technology needs to support, discussions are underway regarding improvements and performance enhancements to the initial 5G mobile communication technology, and physical layer standardization already exists for technologies such as V2X (Vehicle-to-Everything) for assisting autonomous vehicles in making driving decisions and enhancing user convenience by transmitting information about the vehicle's location and status; NR-U (New Radio Unlicensed) for system operation designed to comply with various regulatory requirements in unlicensed frequency bands; NR UE power saving; non-terrestrial networks (NTN); and positioning, among which V2X (Vehicle-to-Everything), NR-U (New Radio Unlicensed), NR UE power saving, non-terrestrial networks (NTN) for providing coverage in areas where communication with terrestrial networks is not possible, and positioning.

[0005] In addition, standardization is underway for the air interface architectures / protocols of the following technologies: Industrial Internet of Things (IIoT) for supporting new services through interoperability and convergence with other industries; IAB (Integrated Access and Backhaul) for providing nodes for network service area extension by supporting wireless backhaul and access links in an integrated manner; mobility enhancements including conditional handover and DAPS (Dual Active Stack) handover; and two-step random access (2-step RACH for NR) for simplifying the random access process. Standardization is also underway for the 5G baseline architecture (e.g., service-based architecture or service-based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and for the system architecture / services for Mobile Edge Computing (MEC) based on UE location reception services.

[0006] With the commercialization of 5G mobile communication systems, the number of connected devices will increase exponentially, necessitating enhanced functionality and performance of 5G mobile communication systems and integrated operation of connected devices. To this end, new research has been initiated related to: Extended Reality (XR) for efficient support of AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality), etc.; 5G performance improvements and complexity reduction through the utilization of Artificial Intelligence (AI) and Machine Learning (ML); AI service support; Metaverse service support; and drone communication.

[0007] Furthermore, this development of 5G mobile communication systems will not only serve as the foundation for developing new waveforms for providing coverage in the terahertz band of 6G mobile communication technology, such as multi-antenna transmission technologies like full-dimensional MIMO (FD-MIMO), array antennas, and massive MIMO; metamaterial-based lenses and antennas for improving terahertz band signal coverage; and high-dimensional spatial multiplexing technologies using OAM (orbital angular momentum) and RIS (reconfigurable smart surfaces); but also as the foundation for developing full-duplex technologies to improve the frequency efficiency of 6G mobile communication technology and enhance system networks; AI-based communication technologies to achieve system optimization and internalize end-to-end AI support by leveraging satellites and AI (artificial intelligence) from the design stage; and next-generation distributed computing technologies to achieve services at complexity levels exceeding the operational capabilities of UEs by utilizing ultra-high-performance communication and computing resources.

Those skilled in the art will understand that the principles of this disclosure can be implemented in any suitably arranged wireless communication system.

[0068] To meet the increased demand for wireless data traffic since the deployment of 4G communication systems and to enable various vertical applications, 5G / NR communication systems have been developed and are currently being deployed. 5G / NR communication systems are considered to be implemented in higher frequency (mmWave) bands (e.g., 28 GHz or 60 GHz) for higher data rates, or in lower frequency bands (e.g., 6 GHz) for robust coverage and mobility support. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are discussed in 5G / NR communication systems.

Figure 1-3B The description is not intended to imply any physical or architectural limitation on the ways in which different embodiments may be implemented. Different embodiments of this disclosure can be implemented in any suitably arranged communication system.

[0072] Figure 1 An example wireless network 100 according to an embodiment of the present disclosure is shown. Figure 1 The embodiments of the wireless network shown are for illustrative purposes only. Other embodiments of the wireless network 100 may be used without departing from the scope of this disclosure.

[0073] like Figure 1 As shown, the wireless network includes gNB 101 (e.g., a base station, BS), gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130 (such as the Internet, a proprietary Internet Protocol (IP) network, or other data network).

[0074] gNB 102 provides wireless broadband access to network 130 to a first plurality of user equipments (UEs) within its coverage area 120. The first plurality of UEs includes UE 111, which may be located in a small business; UE 112, which may be located in an enterprise; UE 113, which may be a WiFi hotspot; UE 114, which may be located in a first residence; UE 115, which may be located in a second residence; and UE 116, which may be a mobile device, such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to a second plurality of UEs within its coverage area 125. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of gNBs 101-103 may communicate with each other and with UEs 111-116 using 5G / NR, Long Term Evolution (LTE), LTE-A Advanced, WiMAX, WiFi, or other wireless communication technologies.

[0075] Depending on the network type, the term "base station" or "BS" can refer to any component (or set of components) configured to provide wireless access to the network, such as a transmitting point (TP), a transmitting and receiving point (TRP), an enhanced base station (eNodeB or eNB), a 5G / NR base station (gNB), a macro cell, a femtocell, a WiFi access point (AP), or other wirelessly enabled device. A base station can provide wireless access according to one or more wireless communication protocols, such as 5G / NR 3rd Generation Partnership Project (3GPP) NR, Long Term Evolution (LTE), LTE-Advanced (LTE-A), High Speed ​​Packet Access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For convenience, the terms "BS" and "TRP" are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Furthermore, depending on the network type, the term "user equipment" or "UE" can refer to any component, such as a "mobile station," "subscriber station," "remote terminal," "wireless terminal," "receiving point," or "user device." For convenience, the terms “user equipment” and “UE” are used in this patent document to refer to a remote wireless device for wireless access to a BS, whether the UE is a mobile device (such as a mobile phone or smartphone) or is generally considered to be a fixed device (such as a desktop computer or vending machine).

[0076] The dashed lines indicate the approximate extent of coverage areas 120 and 125, and are shown as approximately circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB (such as coverage areas 120 and 125) may have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0077] As described in more detail below, one or more of UEs 111-116 include circuitry, programming, or a combination thereof for bundling (or packet / clustering) paging timing. In some embodiments, one or more of gNBs 101-103 include circuitry, programming, or a combination thereof to support bundling (or packet / clustering) paging timing in a wireless communication system.

[0078] although Figure 1 An example of a wireless network is shown, but more can be found on... Figure 1 Various modifications can be made. For example, the wireless network can include any number of gNBs and any number of UEs in any suitable arrangement. Furthermore, gNB 101 can communicate directly with any number of UEs and provide these UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. Additionally, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0079] Figure 2A and 2B Example wireless transmit and receive paths according to embodiments of the present disclosure are illustrated. In the following description, transmit path 200 may be described as being implemented in a gNB (such as gNB 102), and receive path 250 may be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 may be implemented in a gNB, and transmit path 200 may be implemented in a UE. In some embodiments, transmit path 200 and / or receive path 250 are configured to implement and / or support bundled (or packet / cluster) paging timing as described in embodiments of the present disclosure.

[0080] The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-size inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, an N-size fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0081] In transmit path 200, channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity-check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. Serial-to-parallel block 210 converts (such as demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the IFFT / FFT size used in gNB 102 and UE 116. IFFT block 215 of size N performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from IFFT block 215 of size N to generate a serial time-domain signal. Cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. Upconverter 230 modulates (such as upconverts) the output of cyclic prefix addition block 225 to an RF frequency for transmission via the wireless channel. The signal can also be filtered at the baseband before being switched to the RF frequency.

[0082] The transmitted RF signal from gNB 102 reaches UE 116 after passing through the wireless channel, and performs the opposite operation to that at gNB 102. Downconverter 255 downconverts the received signal to the baseband frequency, and cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. FFT block 270 of size N performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0083] Each of gNBs 101-103 can implement a transmission path 200 similar to that sent to UEs 111-116 in the downlink, and a reception path 250 similar to that received from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 200 for sending to gNBs 101-103 in the uplink, and a reception path 250 for receiving from gNBs 101-103 in the downlink.

[0084] Figure 2A and Figure 2B Each component in the system can be implemented using only hardware or a combination of hardware and software / firmware. As a specific example, Figure 2A and 2B At least some components can be implemented in software, while others can be implemented using configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as configurable software algorithms, where the value of size N can be modified depending on the implementation.

[0085] Furthermore, although described as using FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, may be used. It should be understood that for the DFT and IDFT functions, the value of the variable N can be any integer (e.g., 1, 2, 3, 4, etc.), while for the FFT and IFFT functions, the value of the variable N can be any integer that is a power of 2 (e.g., 1, 2, 4, 8, 16, etc.).

[0086] although Figure 2A and 2B An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2A and 2B Make various changes. For example, you can combine, further subdivide, or omit. Figure 2A and 2B It includes various components and allows for the addition of additional components as needed. Furthermore, Figure 2A and 2B This is intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0087] Figure 3A An example UE 116 according to an embodiment of the present disclosure is shown. Figure 3A The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3A This disclosure is not intended to limit the scope to any particular implementation of the UE.

[0088] like Figure 3A As shown, UE 116 includes an antenna 305, a transceiver 310, and a microphone 320. UE 116 also includes a speaker 330, a processor 340, an input / output (I / O) interface (IF) 345, an input 350, a display 355, and memory 360. Memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0089] Transceiver 310 receives incoming RF signals transmitted by the gNB of network 100 from antenna 305. Transceiver 310 down-converts the incoming RF signals to generate intermediate frequency (IF) or baseband signals. The IF or baseband signals are processed by RX processing circuitry in transceiver 310 and / or processor 340, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry sends the processed baseband signals to speaker 330 (e.g., for voice data) or to processor 340 (e.g., for web browsing data).

[0090] The TX processing circuitry in transceiver 310 and / or processor 340 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 340. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. Transceiver 310 up-converts the baseband or IF signal into an RF signal transmitted via antenna 305.

[0091] Processor 340 may include one or more processors or other processing devices and executes OS 361 stored in memory 360 to control the overall operation of UE 116. For example, processor 340 may control transceiver 310 to receive DL channel signals and transmit UL channel signals according to well-known principles. In some embodiments, processor 340 includes at least one microprocessor or microcontroller.

[0092] Processor 340 is also capable of executing other processes and programs residing in memory 360, such as processes for bundling (or grouping / clustering) paging timings, as discussed in more detail below. Processor 340 can move data into or out of memory 360 as needed for executing processes. In some embodiments, processor 340 is configured to execute application 362 based on OS 361 or in response to signals received from gNB or operator. Processor 340 is also coupled to I / O interface 345, which provides UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. I / O interface 345 is the communication path between these accessories and processor 340.

[0093] The processor 340 is also coupled to an input 350 and a display 355. The input 350 includes, for example, a touchscreen, a keypad, etc. The operator of the UE 116 can use the input 350 to input data into the UE 116. The display 355 may be a liquid crystal display, a light-emitting diode display, or other display capable of displaying text and / or at least limited graphics (such as from a website).

[0094] The memory 360 is coupled to the processor 340. A portion of the memory 360 may include random access memory (RAM), and another portion of the memory 360 may include flash memory or other read-only memory (ROM).

[0095] although Figure 3A An example of UE 116 is shown, but it is possible to modify it. Figure 3A Make various changes. For example, Figure 3A The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, processor 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). In another example, transceiver 310 may include any number of transceivers and signal processing chains and can be connected to any number of antennas. Furthermore, although... Figure 3A The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0096] Figure 3B An example gNB 102 according to an embodiment of the present disclosure is shown. Figure 3B The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3B This disclosure is not intended to limit the scope to any particular implementation of gNB.

[0097] like Figure 3B As shown, gNB 102 includes multiple antennas 370a-370n, multiple transceivers 372a-372n, a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0098] Transceivers 372a-372n receive incoming RF signals from antennas 370a-370n, such as signals transmitted by a UE in network 100. Transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are processed by receive (RX) processing circuitry in transceivers 372a-372n and / or controller / processor 378, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. Controller / processor 378 can further process the baseband signals.

[0099] The transmit (TX) processing circuitry in transceivers 372a-372n and / or controller / processor 378 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 378. The TX processing circuitry encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. Transceivers 372a-372n up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0100] The controller / processor 378 may include one or more processors or other processing devices for controlling the overall operation of the gNB 102. For example, the controller / processor 378 may control the transceivers 372a-372n to receive uplink (UL) channel signals and transmit downlink (DL) channel signals according to well-known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may support beamforming or directional routing operations, wherein outgoing / incoming signals from / to multiple antennas 370a-370n are weighted differently to effectively guide outgoing signals to a desired direction. Any of a variety of other functions may be supported by the controller / processor 378 in the gNB 102.

[0101] The controller / processor 378 is also capable of executing programs and other processes residing in memory 380, such as the OS and processes that support, for example, bundled (or grouped / clustered) paging timings, as discussed in more detail below. The controller / processor 378 can move data into or out of memory 380 as needed for the execution process.

[0102] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. Interface 382 can support communication via any suitable wired or wireless connection. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G / NR, LTE, or LTE-A), interface 382 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 382 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 382 includes any suitable architecture supporting communication via a wired or wireless connection, such as Ethernet or a transceiver.

[0103] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, and another portion of memory 380 may include flash memory or other ROM.

[0104] although Figure 3B An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 3B Various changes can be made. For example, gNB102 can include any number of Figure 3B Each component shown. Furthermore, Figure 3B The various components can be combined, further subdivided, or omitted, and additional components can be added as needed.

[0105] Next-generation wireless communication systems (e.g., 5G, B5G, 6G) support not only lower frequency bands but also higher frequency (millimeter wave, terahertz) bands (e.g., 10 GHz to 100 GHz) to achieve higher data rates. To mitigate radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies are being considered in the design of fifth-generation wireless communication systems. Furthermore, next-generation wireless communication systems are expected to address diverse use cases with completely different requirements in terms of data rate, latency, reliability, and mobility. However, the air interface design of next-generation wireless communication systems is anticipated to be flexible enough to serve UEs with vastly different capabilities depending on the UE's needs to cater to the end-customer's use cases and market segment. Several example use cases that next-generation wireless communication systems are expected to address include enhanced mobile broadband (eMBB), massive machine-type communication (m-MTC), and ultra-reliable low-latency communication (URLL). eMBB, with its tens of Gbps data rates, low latency, and high mobility, addresses the market segment representing traditional wireless broadband subscribers who need internet connectivity anytime, anywhere. m-MTC, with its very high connection density, infrequent data transmission, very long battery life, and low mobility, addresses the market segment representing the Internet of Things (IoT) / Internet of Everything (IoE) with its anticipated connectivity of billions of devices. URLL, with its very low latency, very high reliability, and variable mobility, addresses the market segment representing industrial automation applications, vehicle-to-vehicle / vehicle-to-infrastructure communications (foreshadowed as one of the driving forces behind autonomous vehicles).

[0106] In next-generation wireless communication systems operating in higher frequency (mmWave) bands (e.g., 5G, B5G, 6G), UEs and gNBs use beamforming to communicate with each other. Beamforming technology is used to mitigate propagation path loss and increase propagation distance for communication in higher frequency bands. Beamforming uses high-gain antennas to enhance transmit and receive performance. Beamforming can be classified into transmit (TX) beamforming performed at the transmitter and receive (RX) beamforming performed at the receiver. Typically, TX beamforming increases directivity by using multiple antennas to allow the area to be propagated to be densely located in a specific direction. In this case, the aggregation of multiple antennas can be called an antenna array, and each antenna included in the array can be called an array element. Antenna arrays can be configured in various forms such as linear arrays, planar arrays, etc. The use of TX beamforming results in an increase in the directivity of the signal, thereby increasing the propagation distance. Furthermore, since the signal propagates almost entirely outside the direction of directivity, signal interference acting on another receiver is significantly reduced. The receiver can perform beamforming on the RX signal by using an RX antenna array. RX beamforming increases the strength of an RX signal transmitted in a specific direction by allowing propagation to be concentrated in that direction, and excludes signals transmitted in directions other than that specific direction from the RX signal, thus providing a blocking effect against interfering signals. By using beamforming technology, a transmitter can generate multiple transmit beam patterns in different directions. Each of these transmit beam patterns can also be called a transmit (TX) beam. Wireless communication systems operating at high frequencies use multiple narrow TX beams to transmit signals within a cell because each narrow TX beam provides coverage for a portion of the cell. The narrower the TX beam, the higher the antenna gain, and therefore the greater the propagation distance of a signal transmitted using beamforming. Receivers can also generate multiple receive (RX) beam patterns in different directions. Each of these receive patterns can also be called a receive (RX) beam.

[0107] Next-generation wireless communication systems support standalone operation mode and dual connectivity (DC). In DC, multiple Rx / Tx UEs can be configured to utilize resources provided by two different nodes (or NBs) via a non-ideal backhaul connection. One node acts as the primary node (MN), and the other acts as the secondary node (SN). The MN and SN are connected via a network interface, and at least the MN is connected to the core network. NR also supports multiple RAT dual connectivity (MR-DC) operation, whereby a UE in the RRC_CONNECTED state is configured to utilize radio resources provided by two different schedulers located in two different nodes via a non-ideal backhaul connection and providing E-UTRA (i.e., if the node is an ng-eNB) or NR access (i.e., if the node is a gNB). In NR, for a UE in the RRC_CONNECTED state without a CA / DC configuration, only one serving cell exists, including the primary cell. For a UE in the RRC_CONNECTED state with a CA / DC configuration, the term "serving cell" is used to refer to the set of cells including the primary cell and all secondary cells. In NR, the term Primary Cell Group (MCG) refers to a group of serving cells associated with a primary node, including a PCell and one or more optional SCells. In NR, the term Secondary Cell Group (SCG) refers to a group of serving cells associated with a secondary node, including a PSCell and one or more optional SCells. In NR, the term PCell (primary cell) refers to a serving cell in the MCG that operates on the primary frequency, where the UE performs an initial connection establishment procedure or initiates a connection re-establishment procedure. In NR, for a UE configured with CA, an Scell ​​is a cell that provides additional radio resources above a special cell. The primary SCG cell (PSCell) is a serving cell in the SCG where the UE performs random access during a reconfiguration procedure with synchronization. For dual connectivity operation, the term SpCell (i.e., special cell) refers to either the PCell of the MCG or the PSCell of the SCG; otherwise, the term special cell refers to the PCell.

[0108] In next-generation wireless communication systems, Node Bs (gNBs) or base stations in a cell broadcast synchronization signals and PBCH blocks (also known as synchronization signal blocks (SSBs)), including primary and secondary synchronization signals (PSS, SSS) as well as system information. System information includes common parameters required for communication within the cell. In next-generation wireless communication systems (also known as next-generation radio or NR), system information (SI) is divided into MIBs and multiple SIBs, where: the MIB is transmitted on the BCH with a period of 80 milliseconds, repeating within 80 milliseconds, and it includes the parameters required to obtain SIB1 from the cell. SIB1 is transmitted on the DL-SCH with a period of 160 ms and variable transmission repetition. The default transmission repetition period of SIB1 is 20 ms, but the actual transmission repetition period depends on the network implementation. For SSB and CORESET multiplexing pattern 1, the SIB1 repetition transmission period is 20 ms. For SSB and CORESET multiplexing patterns 2 / 3, the SIB1 transmission repetition period is the same as the SSB period. SIB1 includes information about the availability and scheduling of other SIBs (e.g., SIB-to-SI message mapping, periodicity, SI window size), indicating whether one or more SIBs are provided only on demand, and in that case, the configuration required for the UE to execute an SI request. SIB1 is a cell-specific SIB; SIBs other than SIB1 and posSIB are carried in SystemInformation (SI) messages transmitted on the DL-SCH. Only SIBs or posSIBs with the same periodicity can be mapped to the same SI message. SIBs and posSIBs are mapped to different SI messages. Each SI message is transmitted within a periodically occurring time-domain window (called an SI window of equal length for all SI messages). Each SI message is associated with an SI window, and the SI windows for different SI messages do not overlap. That is, within an SI window, only the corresponding SI message is transmitted. SI messages can be transmitted multiple times within an SI window. Using the indications in SIB1, any SIB or posSIB other than SIB1 can be configured to be cell-specific or region-specific. Cell-specific SIBs are applicable only within the cell providing the SIB, while area-specific SIBs are applicable within an area called an SI area, which includes one or more cells and is identified by the systemInformationAreaID. The mapping from SIBs to SI messages is configured in the schedulingInfoList, while the mapping from posSIBs to SI messages is configured in the pos-SchedulingInfoList. Each SIB is contained in only a single SI message, and each SIB and posSIB is included at most once in that SI message.For UEs in the RRC_CONNECTED state, for example, if the UE has an active BWP in the common search space that is not configured to listen for system information or paging, or upon request from the UE, the network can provide system information via dedicated signaling using the RRCReconfiguration message. In the RRC_CONNECTED state, the UE obtains the required SIB from the PCell. For PSCells and SCells, the network provides the required SI via dedicated signaling (i.e., within the RRCReconfiguration message). However, the UE obtains the MIB of the PSCell to obtain the SFN timing of the SCG (which may be different from the MCG). When the relevant SI of the SCell changes, the network releases and adds the relevant SCell. For PSCells, the required SI can only be changed through a reconfiguration with synchronization.

[0109] In the next wireless communication system, random access (RA) is supported. Random access (RA) is used to achieve uplink (UL) time synchronization. RA is used during initial access, handover, Radio Resource Control (RRC) connection re-establishment procedures, scheduling request transmission, secondary cell group (SCG) addition / modification, beam fault recovery, and data or control information transmission in the UL by asynchronous UEs in the RRC CONNECTED state. Several types of random access procedures are supported, such as contention-based random access and contention-free random access, and each of these can be one of a 2-step or 4-step random access.

[0110] In next-generation wireless communication systems, the Physical Downlink Control Channel (PDCCH) is used to schedule DL transmissions on the PDSCH and UL transmissions on the PUSCH. The downlink control information (DCI) on the PDCCH includes: downlink assignment containing at least modulation and coding formats, resource allocation, and hybrid ARQ information related to the DL-SCH; and uplink scheduling authorization containing at least modulation and coding formats, resource allocation, and hybrid ARQ information related to the UL-SCH. Besides scheduling, the PDCCH can also be used for: activating and deactivating configured PUSCH transmissions with configured authorizations; activating and deactivating PDSCH semi-persistent transmissions; informing one or more UEs of slot formats; informing one or more UEs that it can be assumed there are no PRB and OFDM symbols for transmissions to that UE; transmitting TPC commands for PUCCH and PUSCH; transmitting one or more TPC commands for SRS transmissions performed by one or more UEs; switching the active bandwidth portion of a UE; and initiating random access procedures. The UE listens for a set of PDCCH candidates in one or more configured control resource sets (CORESETs) according to the configured listening time in the corresponding search space configuration. A CORESET comprises a set of PRBs with durations of 1 to 3 OFDM symbols. Within a CORESET, Resource Elements (REGs) and Control Channel Elements (CCEs) are defined, with each CCE comprising a set of REGs. The control channel is formed by the aggregation of CCEs. Different code rates for the control channel are achieved by aggregating different numbers of CCEs. Interleaved and non-interleaved CCE-to-REG mappings are supported in a CORESET. Polar coding is used for the PDCCH. Each resource element group carrying the PDCCH carries its own DMRS. QPSK modulation is used for the PDCCH.

[0111] In next-generation wireless communication systems (e.g., 5G), the gNB signals a list of search space configurations for each configuration's BWP of the serving cell, where each search configuration is uniquely identified by a search space identifier. The search space identifier is unique within the serving cell's BWP. The gNB explicitly signals the identifier of the search space configuration to be used for specific purposes such as paging reception, SI reception, and random access response reception for each configuration's BWP. In NR, the search space configuration includes the parameters Monitoring-periodicity-PDCCH-slot, Monitoring-offset-PDCCH-slot, Monitoring-symbols-PDCCH-within-slot, and duration. The UE uses the parameters Monitoring-periodicity-PDCCH-slot, Monitoring-offset-PDCCH-slot, and Monitoring-symbols-PDCCH-within-slot to determine the timing of PDCCH listening within a time slot. The PDCCH listening opportunity is located within the duration from time slot "x" to x+, where time slot "x" in radio frame numbered "y" satisfies the following equation 1:

[0112] [Equation 1]

[0113] (y) (Number of time slots in a radio frame) + x – Monitoring-offset-PDCCH-slot) mod (Monitoring-periodicity-PDCCH-slot) = 0;

[0114] The start symbol of the PDCCH listening opportunity in each slot with a PDCCH listening opportunity is given by Monitoring-symbols-PDCCH-within-slot. The length of the PDCCH listening opportunity (in symbols) is given in the CORESET associated with the search space. The search space configuration includes the identifier of the CORESET configuration associated with the search space configuration. The gNB signals the CORESET configuration list to the BWP for each configuration of the serving cell, where each CORESET configuration is uniquely identified by the CORESET identifier. The CORESET identifier is unique in the BWP of the serving cell. Note that each radio frame has a duration of 10 ms. Each radio frame is identified by a radio frame number or a system frame number. Each radio frame includes several time slots, where the number of time slots in the radio frame and the duration of the time slots depend on the subcarrier spacing. The number of time slots in the radio frame and the duration of the time slots for each supported SCS are predefined in the NR. Each CORESET configuration is associated with a TCI (Transmission Configuration Indicator) status list. Each TCI status configures a DL RS ID (SSB or CSI RS). The TCI status list corresponding to the CORESET configuration is signaled by the gNB via RRC signaling. One of the TCI statuses in the TCI status list is activated by the gNB and indicated to the UE. The TCI status indicates the DL TX beam used by the gNB to transmit PDCCH during PDCCH listening in the search space (the DL TX beam and the SSB / CSI RS of the TCI status are QCL).

[0115] In next-generation wireless communication systems, bandwidth adaptation (BA) is supported. With BA, the UE's receive and transmit bandwidth does not need to be as large as the cell's bandwidth and can be adjusted: bandwidth can be commanded to change (e.g., shrinking during periods of low activity to save power); location can be moved in the frequency domain (e.g., to increase scheduling flexibility); and subcarrier spacing can be commanded to change (e.g., to allow different services). A subset of the cell's total cell bandwidth is called the Bandwidth Part (BWP). BA is implemented by configuring BWPs for the UE in an RRC-connected state and telling the UE which of the configured BWPs is currently active. When BA is configured, the UE only listens to the PDCCH on one active BWP; that is, it does not listen to the PDCCH on the entire DL frequency of the serving cell. In RRC-connected state, for each configured serving cell (i.e., PCell or SCell), the UE is configured with one or more DL and UL BWPs. For an active serving cell, there is one active UL and DL BWP at any given time. Serving cell BWP handover is used to activate inactive BWPs and deactivate active BWPs at specific times. BWP handover is controlled by the PDCCH indicating downlink assignment or uplink grant, by the bwp-InactivityTimer, by RRC signaling, or by the MAC entity itself when initiating a random access procedure. When adding a SpCell or activating an SCell, the DL BWP and UL BWP indicated by firstActiveDownlinkBWP-Id and firstActiveUplinkBWP-Id, respectively, are active without receiving the PDCCH indicating downlink assignment or uplink grant. The active BWP of the serving cell is indicated by RRC or PDCCH. For unpaired spectrum, the DL BWP is paired with the UL BWP, and BWP handover is common to both UL and DL. When the BWP inactivity timer expires, the UE switches the active DL BWP to the default DL BWP or the initial DL BWP (if the default DL BWP is not configured).

[0116] In fifth-generation (also known as NR or New Radio) wireless communication systems, a UE can be in one of the following RRC states: RRC IDLE, RRC INACTIVE, and RRC CONNECTED. Paging allows the network to reach UEs in the RRC_IDLE and RRC_INACTIVE states via paging messages, and to notify UEs in the RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED states of system information changes and ETWS (Earthquake and Tsunami Warning System) / CMAS (Commercial Mobile Alert System) indications via short messages. Both paging messages and short messages are addressed on the PDCCH using P-RNTI, but the former is transmitted on the PCCH logical channel (the TB carrying the paging message is transmitted on the Physical Downlink Shared Channel [PDSCH]), while the latter is transmitted directly on the PDCCH.

[0117] When in RRC_IDLE state, the UE listens to the paging channel for paging initiated by the CN. When in RRC_INACTIVE state, the UE listens to the paging channel for both paging initiated by the RAN and paging initiated by the CN. However, the UE does not need to continuously listen to the paging channel. Discontinuous Paging Reception (DRX) is defined, where a UE in RRC_IDLE or RRC_INACTIVE only needs to listen to the paging channel during one paging opportunity (PO) in each DRX cycle.

[0118] A PO is a set of PDCCH listening times and may include multiple time slots (e.g., subframes or OFDM symbols) in which paging DCI (i.e., PDCCH addressed to P-RNTI) can be transmitted. A paging frame (PF) is a radio frame and may contain one or more POs or the start point of a PO. A PO associated with a PF may begin within or after the PF.

[0119] In multi-beam operation, the UE assumes that the same paging message and the same short message are repeated in all transmitted beams; therefore, the selection of the beam used to receive the paging message and short message depends on the UE's implementation. The paging message is the same for both RAN-initiated and CN-initiated paging. The UE initiates an RRC connection recovery procedure upon receiving a RAN-initiated paging. If the UE receives a CN-initiated paging while in the RRC_INACTIVE state, the UE moves to the RRC_IDLE state and notifies the NAS.

[0120] The PF and PO used for paging are determined by the following formula (by the UE and the base station, such as gNB):

[0121] The SFN of PF is determined by the following formula:

[0122] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N).

[0123] The index (i_s) of the index indicating the PO is determined by the following formula:

[0124] i_s=floor(UE_ID / N) mod Ns.

[0125] The PDCCH listening timing for paging is determined by the pagingSearchSpace. When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI (also known as SIB1). The PDCCH listening timing for RMSI depends on the SS / PBCH block and the CORESET multiplexing pattern. The SS / PBCH block (SSB) and CORESET multiplexing pattern are signaled in the MIB and can be one of Pattern 1, Pattern 2, and Pattern 3. For Pattern 1, the set of PDCCH listening timings occurs every 20ms. For Patterns 2 / 3, the set of PDCCH listening timings occurs periodically every SSB periodicity. For Pattern 3, the RMSI PDCCH listening timing is frequency-division multiplexed with the SSB. For Pattern 2, the RMSI PDCCH listening timing is offset relative to the SSB.

[0126] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns is either 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0127] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is "S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent according to ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO used for paging. The [S+K] PDCCH monitoring times correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time for paging in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0128] The following parameters are used to calculate PF and i_s above:

[0129] T: UE's DRX period.

[0130] N: The total number of paging frames in T; N is one of T, T / 2, T / 4, T / 8, and T / 16.

[0131] Ns: The number of paging opportunities for PF; NS is one of 1, 2, or 4.

[0132] PF_offset: The offset used to determine PF.

[0133] UE_ID: If the UE is operating in eDRX: 5G-S-TMSI mod 4096, otherwise 5G-S-TMSI mod 1024.

[0134] The parameters Ns, nAndPagingFrameOffset, and the length of the default DRX period are signaled in SIB1. The values ​​of N and PF_offset are derived from the parameter nAndPagingFrameOffset, as shown in Table 1 below.

[0135] [Table 1]

[0136]

[0137] The value of oneSixteenthT corresponds to N=T / 16, the value of oneEighthT corresponds to N=T / 8, and so on.

[0138] If pagingSearchSpace is set to zero and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3, then for a 5 or 10 ms ssb-periodicityServingCell, N can be set to one of {oneT, halfT, QuartE, oneEighthT, oneSixteenthT}. For a 20 ms ssb-periodicityServingCell, N can be set to one of {halfT, QuartT, oneEighthT, oneSixteenthT}. For a 40 ms ssb-periodicityServingCell, N can be set to one of {quartRT, oneEighthT, oneSixteenthT}. For an 80 ms ssb-periodicityServingCell, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms ssb-periodicityServingCell, N can be set to oneSixteenthT.

[0139] If pagingSearchSpace is set to zero and if the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, QuartEr, oneEighthT, oneSixteenthT}.

[0140] If pagingSearchSpace is not set to zero, then N can be configured as one of {oneT, halfT, QuartEr, oneEighthT, oneSixteenthT}.

[0141] If the UE does not have a 5G-S-TMSI, for example when the UE has not yet registered on the network, then the UE should use UE_ID = 0 as the default identifier in the PF and i_s formulas above.

[0142] In existing methods, multiple paging frames configured by the network are evenly distributed over time. The UE is distributed across these paging frames. Each UE listens for the PO in its PF during each DRX cycle.

[0143] Figure 4A Example 402 of a uniformly distributed paging frame according to an embodiment of the present disclosure is shown. Figure 4A The embodiment of uniformly distributed paging frames is for illustrative purposes only. Different embodiments of uniformly distributed paging frames may be used without departing from the scope of this disclosure.

[0144] like Figure 4A As shown, the PF appears once every 4 radio frames. There are 4 PFs in every 32 radio frame period. UEs in the cell are distributed to these PFs based on their UE_ID.

[0145] although Figure 4A Example 402 shows a uniformly distributed paging frame, but it is possible to... Figure 4A Various changes can be made. For example, the number of power supplies (PFs), the PF intervals, etc., can be changed according to specific needs.

[0146] One problem with distributed Paging is that the network (e.g., base stations) wakes up frequently to deliver paging messages, leading to increased energy consumption. Figure 4B This illustrates a scheme that bundles (also known as clusters or packets) PFs at the start of a DRX cycle to reduce the number of times the network wakes up to deliver paging. Bundling (or packet / clustering) can also minimize frequent transmissions of signals such as SSB / PEI that aid in paging reception.

[0147] Figure 4B Example 422 of a bundled paging frame according to an embodiment of the present disclosure is shown. Figure 4B The embodiments of bundled paging frames are for illustrative purposes only. Different embodiments of bundled paging frames may be used without departing from the scope of this disclosure.

[0148] like Figure 4B As shown, the PF appears in each radio frame for the first 8 radio frames in a period of 32 radio frames. UEs in the cell are assigned to these PFs based on their UE_ID.

[0149] Although Figure 4B Example 422 of a bundled paging frame is shown, but it can be modified accordingly. Figure 4B Various changes can be made. For example, the quantity, periodicity, etc. of PF can be changed according to specific needs.

[0150] In 5G wireless communication systems, the maximum SSB periodicity is 160ms. Longer SSB periods (e.g., 320ms, 640ms, ...) can improve network energy efficiency. However, longer SSB periods affect the determination of PF / PO in pagingSearchSpace 0. Some of the PF / PO determined based on the current formula / configuration will become invalid, such as... Figure 5 As can be seen in the document. Enhancements for determining PF / PO for longer SSB periods are provided in this disclosure.

[0151] Figure 5 An example 500 of SSB periodicity according to an embodiment of the present disclosure is shown. Figure 5The embodiments of SSB periodicity are for illustrative purposes only. Different embodiments of SSB periodicity may be used without departing from the scope of this disclosure.

[0152] Figure 5 The various PFs configured by the network are shown. UEs are distributed across these PFs based on their UE_ID. Some UEs will be mapped to PF Bs where no PDCCH listening time for paging is available. Note that when pagingSearchSpace is zero, the PDCCH listening time for paging is the same as the SSB time if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3.

[0153] although Figure 5 Example 500 of SSB periodicity is shown, but it is possible to... Figure 5 Various changes can be made. For example, the quantity, periodicity, etc. of PF can be changed according to specific needs.

[0154] As previously described, PFs can be bundled to reduce multiple wake-ups by the network (e.g., base stations) for paging. In one embodiment, PF / PO can be bundled periodically for short durations (D), such as... Figure 6 As shown.

[0155] Figure 6 Example 600 of paging frames being bundled according to an embodiment of the present disclosure is shown. Figure 6 The embodiments of bundled paging frames are for illustrative purposes only. Different embodiments of bundled paging frames may be used without departing from the scope of this disclosure.

[0156] exist Figure 6 In the example, several PFs (N1) are bundled within a duration (D) of radio frames. The duration (D) appears periodically at intervals / cycles / periods X. The number of PFs (N1) within duration D is signaled by the network (e.g., a base station). For example, N1 = D, D / 2, D / 4, D / 8, D / 16… etc. N1 equals D means that every radio frame in duration D is a PF. N1 equals D / 2 means that every other radio frame in duration D is a PF. N1 equals D / 4 means that every fourth radio frame in duration D is a PF. N1 equals D / 8 means that every eighth radio frame in duration D is a PF. N1 equals D / 16 means that every sixteenth radio frame in duration D is a PF. The UE is distributed across these PFs in duration D. In one embodiment, X may be the length of a cell DTX cycle used for network power saving.

[0157] Although Figure 6 Example 600 of bundling paging frames is shown, but it is possible to... Figure 6 Various changes can be made. For example, the duration, periodicity, and other characteristics of radio frames can be changed according to specific needs.

[0158] In one embodiment, the UE and gNB are as follows: Figure 7 The PF / PO used for paging is determined as shown.

[0159] Figure 7 A method 700 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 7 The embodiments of the methods shown are for illustrative purposes only. Figure 7 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0160] exist Figure 7 In examples, such as Figure 1 UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0161] In step 710, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE can receive the paging configuration from the camping cell, or the UE can receive the paging configuration from another cell. The paging configuration includes:

[0162] -Ns′: The number of paging opportunities in the paging frame within the duration D;

[0163] -N1: The number of paging frames in duration D

[0164] - Offset

[0165] -X: The interval at which the bundled PF appears periodically.

[0166] -D: The duration in which the PF is bound (or configured)

[0167] -nrofPDCCH-MonitoringOccasionPerSSB-InPO. This can be signaled in system information (e.g., SIB1).

[0168] -firstPDCCH-MonitoringOccasionOfPO. This can be signaled in the system information (e.g., SIB1) used for paging in a BWP configured by initialDownlinkBWP. For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0169] -pagingSearchSpace: The ID of the search space used for paging.

[0170] The configuration can be per BWP or per cell. Some parameters (such as Ns′, N1, Offset, X, D, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0171] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0172] In step 720, the SFN of PF is determined by the following formula:

[0173] (SFN + offset) mod T = (D div N1) (UE_ID mod N1), or

[0174] SFN mod T = (D div N1) (UE_ID mod N1), "div" is the mathematical operator indicating division. " is the mathematical operator indicating multiplication.

[0175] “D div N1” is an integer where N1 = D, D / 2, D / 4, D / 8, D / 16, ... etc. In an embodiment, D div N1 can be replaced by a parameter K, which can be signaled by the network, and the SFN of the PF is determined by the following formula: (SFN + offset) mod T = (K) (UE_ID mod N1), or

[0176] SFN mod T = (K) (UE_ID mod N1), where N1 is the number of PFs, N1 = 1, 2, 3, etc.

[0177] In step 730, the index (i_s) indicating the index of PO is determined by the following formula:

[0178] i_s=floor(UE_ID / N1) mod Ns′.

[0179] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0180] At step 740, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0181] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0182] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is "S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent according to ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO used for paging. The S+K] PDCCH monitoring opportunities correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring opportunities for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring opportunity for paging in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring opportunity number for the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0183] In step 750, the UE listens for paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0184] In one embodiment, if the UE and the cell support LP WUS, a UE in the RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit in the PEI shared by all UEs is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0185] In an alternative embodiment, the UE receives first and second paging configurations for listening to paging from the camping cell. The paging configurations may be signaled by the camping cell in system information (e.g., SIB1). The UE may receive the paging configuration from the camping cell, or the UE may receive the paging configuration from another cell.

[0186] The first paging configuration includes:

[0187] -Ns: Number of paging opportunities for PF

[0188] -N: Number of paging frames

[0189] -PF_Offset: Paging frame offset

[0190] -nrofPDCCH-MonitoringOccasionPerSSB-InPO

[0191] -firstPDCCH-MonitoringOccasionOfPO

[0192] -pagingSearchSpace: The ID of the search space used for paging.

[0193] The second paging configuration includes:

[0194] -Ns′: Number of paging opportunities for PF

[0195] -N1: Number of paging frames in duration (D)

[0196] -Offset

[0197] -X: The interval at which the bundled PF (or the PF configured in duration D) occurs periodically.

[0198] -D: Bind (or configure the duration of the PF)

[0199] -nrofPDCCH-MonitoringOccasionPerSSB-InPO′

[0200] - firstPDCCH-MonitoringOccasionOfPO′

[0201] -pagingSearchSpace′: The ID of the search space used for paging.

[0202] In one embodiment, the offset may not be signaled in the second paging configuration, and when the second paging configuration is used, the UE uses / applies the PF_Offset from the first paging configuration as the offset. This applies if the network power-saving mode is activated and / or if an indication is received from the network to use the PF bundling configuration (i.e., the second paging configuration) and / or if the UE supports the PF bundling configuration (i.e., the second paging configuration).

[0203] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0204] The SFN of PF is determined by the following formula:

[0205] (SFN + offset) mod T = (D div N1) (UE_ID mod N1), or

[0206] SFN mod T = (D div N1) (UE_ID mod N1).

[0207] “D div N1” is an integer where N1 = D, D / 2, D / 4, D / 8, D / 16... etc. In one embodiment, D div N1 can be replaced by a parameter K, which can be signaled by the network, and the SFN of the PF is determined by the following formula: (SFN + offset) mod T = (K) (UE_ID mod N1), or

[0208] SFN mod T = (K) (UE_ID mod N1), where N1 is the number of PFs, N1 = 1, 2, 3, and so on.

[0209] The index (i_s) indicating the index of the PO is determined by the following formula:

[0210] i_s=floor(UE_ID / N1) mod Ns′.

[0211] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0212] The PDCCH listening timing for paging is determined based on pagingSearchSpace′, firstPDCCH-MonitoringOccasionOfPO′, and nrofPDCCH-MonitoringOccasionPerSSB-InPO′ (if configured).

[0213] In one embodiment, `pagingSearchSpace'` can be the same as `pagingSearchSpace`. In one embodiment, if `pagingSearchSpace` is not configured, then `pagingSearchSpace` is used. In one embodiment, `firstPDCCH-MonitoringOccasionOfPO'` can be the same as `firstPDCCH-MonitoringOccasionOfPO`. In one embodiment, if `firstPDCCH-MonitoringOccasionOfPO'` is not configured, then `firstPDCCH-MonitoringOccasionOfPO` is used. In one embodiment, if `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` is not configured, then `nrofPDCCH-MonitoringOccasionPerSSB-InPO` can be used. In one embodiment, `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` can be the same as `nrofPDCCH-MonitoringOccasionPerSSB-InPO`. In one embodiment, `Ns'` can be the same as `Ns`. In one embodiment, if `Ns'` is not configured, then `Ns` can be used.

[0214] Otherwise (e.g., if network power saving mode is not activated, or if no instruction to use PF bundling configuration is received from the network, or if the UE does not support PF bundling configuration):

[0215] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0216] The SFN of PF is determined by the following formula:

[0217] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N).

[0218] The index (i_s) indicating the index of the PO is determined by the following formula:

[0219] i_s=floor(UE_ID / N) mod Ns.

[0220] The PDCCH listening timing used for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured).

[0221] The UE listens for paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI). The gNB sends paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI).

[0222] The UE can also indicate its ability to support PF / PO binding when it is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0223] although Figure 7 An example of a method 700 for binding paging timing is shown, but it is possible to modify it further. Figure 7 Various changes were made. For example, although it is shown as a series of steps, Figure 7 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0224] In one embodiment, PF can be periodically bundled for short durations (D), such as Figure 8 As shown.

[0225] Figure 8 Another example 800 of paging frames being bundled according to embodiments of the present disclosure is shown. Figure 8The embodiments of bundled paging frames are for illustrative purposes only. Different embodiments of bundled paging frames may be used without departing from the scope of this disclosure.

[0226] exist Figure 8 In the example, several PFs (N1) are bundled within the duration (D) of a radio frame. The duration (D) appears periodically at intervals / cycles / periods X. The number of PFs within the duration D is D. The UEs are distributed among the PFs within the duration D. In one embodiment, X may be the length of a cell DTX cycle used for network power saving.

[0227] Although Figure 8 Example 800 of bundling paging frames is shown, but it is possible to... Figure 8 Various changes can be made. For example, the duration, periodicity, and other characteristics of radio frames can be changed according to specific needs.

[0228] In one embodiment, the UE and gNB are as follows: Figure 9 The PF / PO used for paging is determined as shown.

[0229] Figure 9 Another method 900 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 9 The embodiments of the methods shown are for illustrative purposes only. Figure 9 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0230] exist Figure 9 In examples, such as Figure 1 UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0231] In step 910, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE can receive the paging configuration from the camping cell, or the UE can receive the paging configuration from another cell. The paging configuration includes:

[0232] -Ns′: Number of paging opportunities for PF

[0233] -Offset

[0234] -X: The interval at which the bundled PF appears periodically.

[0235] -D: The duration for which a PF is bound (or configured), where the number of PFs is equal to D.

[0236] -nrofPDCCH-MonitoringOccasionPerSSB-InPO. This can be signaled in system information (e.g., SIB1).

[0237] -firstPDCCH-MonitoringOccasionOfPO. For paging in a BWP configured by initialDownlinkBWP, this can be signaled in system information (e.g., SIB1). For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0238] -pagingSearchSpace: The ID of the search space used for paging.

[0239] The configuration can be per BWP or per cell. Some parameters (such as Ns′, Offset, X, D, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0240] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0241] In step 920, the SFN of PF is determined by the following formula:

[0242] (SFN + offset) mod T = (UE_ID mod D), or

[0243] SFN mod T = (UE_ID mod D).

[0244] In step 930, the index (i_s) indicating the index of PO is determined by the following formula:

[0245] i_s=floor(UE_ID / D) mod Ns′.

[0246] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0247] In step 940, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0248] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0249] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent as determined by ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO... The S+K] PDCCH monitoring times for paging correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0250] In step 950, the UE listens for paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0251] In one embodiment, if the UE and the cell support LP WUS, a UE in RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for a PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit in the PEI shared by all UEs is set to 1), then the UE subsequently listens for a determined PO (using MR) and receives the paging message.

[0252] In an alternative embodiment, the UE receives first and second paging configurations for listening to paging from the camping cell. The paging configurations may be signaled by the camping cell in system information (e.g., SIB1). The UE may receive the paging configuration from the camping cell, or the UE may receive the paging configuration from another cell.

[0253] The first paging configuration includes:

[0254] -Ns: Number of paging opportunities for PF

[0255] -N: Number of paging frames

[0256] -PF_Offset: Paging frame offset

[0257] -nrofPDCCH-MonitoringOccasionPerSSB-InPO

[0258] -firstPDCCH-MonitoringOccasionOfPO

[0259] -pagingSearchSpace: The ID of the search space used for paging.

[0260] The second paging configuration includes:

[0261] -Ns′: Number of paging opportunities for PF

[0262] -Offset

[0263] -X: The interval at which the bundled PF appears periodically.

[0264] -D: The duration for which a PF is bound (or configured), where the number of PFs is equal to D.

[0265] -nrofPDCCH-MonitoringOccasionPerSSB-InPO′

[0266] -firstPDCCH-MonitoringOccasionOfPO′

[0267] -pagingSearchSpace′: The ID of the search space used for paging.

[0268] - In one embodiment, the offset may not be signaled in the second paging configuration, and when the second paging configuration is used, the UE uses / applies the PF_Offset from the first paging configuration as the offset.

[0269] If network power saving mode is activated and / or if an instruction to use PF bundling configuration (i.e., second paging configuration) is received from the network and / or if the UE supports PF bundling configuration (i.e., second paging configuration):

[0270] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0271] The SFN of PF is determined by the following formula:

[0272] (SFN + offset) mod T = (UE_ID mod D), or

[0273] SFN mod T = (UE_ID mod D).

[0274] The index (i_s) indicating the index of the PO is determined by the following formula:

[0275] i_s=floor(UE_ID / D) mod Ns′.

[0276] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0277] The PDCCH listening timing for paging is determined based on pagingSearchSpace′, firstPDCCH-MonitoringOccasionOfPO′, and nrofPDCCH-MonitoringOccasionPerSSB-InPO′ (if configured).

[0278] In one embodiment, `pagingSearchSpace'` can be the same as `pagingSearchSpace`. In one embodiment, if `pagingSearchSpace'` is not configured, then `pagingSearchSpace` is used. In one embodiment, `firstPDCCH-MonitoringOccasionOfPO'` can be the same as `firstPDCCH-MonitoringOccasionOfPO`. In one embodiment, if `firstPDCCH-MonitoringOccasionOfPO'` is not configured, then `firstPDCCH-MonitoringOccasionOfPO` is used. In one embodiment, if `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` is not configured, then `nrofPDCCH-MonitoringOccasionPerSSB-InPO` can be used. In one embodiment, `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` can be the same as `nrofPDCCH-MonitoringOccasionPerSSB-InPO`.

[0279] Otherwise (e.g., if network power saving mode is not activated, or if no instruction to use PF bundling configuration is received from the network, or if the UE does not support PF bundling configuration (i.e., second paging configuration)):

[0280] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0281] The SFN of PF is determined by the following formula:

[0282] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N)

[0283] The index (i_s) indicating the index of the PO is determined by the following formula:

[0284] i_s = floor(UE_ID / N) mod Ns

[0285] The PDCCH listening timing used for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured).

[0286] The UE listens for paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI). The gNB sends paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI).

[0287] The UE can also indicate its ability to support PF / PO binding when it is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0288] although Figure 9 An example of a method 900 for binding paging timing is shown, but it is possible to modify... Figure 9 Various changes were made. For example, although it is shown as a series of steps, Figure 9 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0289] In one embodiment, the PF (or a reference frame for PO determination or a reference frame for PO clustering) appears periodically, such as Figure 10 As shown.

[0290] Figure 10 Another example 1000 of paging frames being bundled according to embodiments of the present disclosure is shown. Figure 10 The embodiments of bundled paging frames are for illustrative purposes only. Different embodiments of bundled paging frames may be used without departing from the scope of this disclosure.

[0291] exist Figure 10 In the example, the PF (or the reference frame used for PO determination or the reference frame used for PO clustering) appears periodically with an interval / cycle / period X.

[0292] although Figure 10 Example 1000 of bundled paging frames is shown, but it is possible to... Figure 10 Various changes can be made. For example, the PF or bundled PO, cycle, etc., can be changed according to specific needs.

[0293] In one embodiment, the UE and gNB are as follows: Figure 11 The PF / PO used for paging is determined as shown.

[0294] Figure 11 Another method 1100 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 11 The embodiments of the methods shown are for illustrative purposes only. Figure 11 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0295] exist Figure 11 In this example, it should be noted that the PF is actually a reference frame used for determining the PO or for the PO cluster.

[0296] exist Figure 11 In examples, such as Figure 1 UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0297] In step 1110, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE can receive the paging configuration from the camping cell, or the UE can receive the paging configuration from another cell. The paging configuration includes:

[0298] -Ns′: Number of paging opportunities

[0299] -Offset: Offset

[0300] -X: The interval between PF / reference frame / cluster PO

[0301] -nrofPDCCH-MonitoringOccasionPerSSB-INPO: This can be used to signal in system information (e.g., SIB1).

[0302] -firstPDCCH-MonitoringOccasionOfPO: For paging in a BWP configured by initialDownlinkBWP, this can be signaled in system information (e.g., SIB1). For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0303] -pagingSearchSpace: The ID of the search space used for paging.

[0304] The configuration can be per BWP or per cell. Some parameters (such as Ns′, N1, PF_Offset, X, D, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0305] The PF and PO used for paging are determined by the following formula (by the UE and the base station, such as gNB):

[0306] In step 1120, the SFN of PF is determined by the following formula:

[0307] (SFN + offset) mod T = 0 or SFN mod T = offset, or

[0308] SFN mod T = 0.

[0309] In step 1130, the index (i_s) indicating the index of PO is determined by the following formula:

[0310] i_s=UE_ID mod Ns′.

[0311] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0312] At step 1140, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0313] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0314] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent as determined by ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO... The S+K] PDCCH monitoring times for paging correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0315] In step 1150, the UE listens for paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0316] In one embodiment, if the UE and the cell support LP WUS, a UE in RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit shared by all UEs exists in the PEI and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0317] In an alternative embodiment, the UE receives first and second paging configurations for listening to paging from the camping cell. The paging configurations may be signaled by the camping cell in system information (e.g., SIB1). The UE may receive the paging configuration from the camping cell, or the UE may receive the paging configuration from another cell.

[0318] The first paging configuration includes:

[0319] -Ns: Number of paging opportunities for PF

[0320] -N: Number of paging frames

[0321] -PF_Offset: Paging frame offset

[0322] -nrofPDCCH-MonitoringOccasionPerSSB-InPO

[0323] -firstPDCCH-MonitoringOccasionOfPO

[0324] -pagingSearchSpace: The ID of the search space used for paging.

[0325] The second paging configuration includes:

[0326] -Ns′: Number of paging opportunities

[0327] -Offset: Offset

[0328] -X: Interval

[0329] -nrofPDCCH-MonitoringOccasionPerSSB-InPO′

[0330] -firstPDCCH-MonitoringOccasionOfPO′

[0331] -pagingSearchSpace′: The ID of the search space used for paging.

[0332] - In implementation, the offset may not be signaled in the second paging configuration, and when the second paging configuration is used, the UE uses / applies the PF_Offset from the first paging configuration as the offset.

[0333] If network power saving mode is activated and / or if an instruction to use PF bundling configuration is received from the network and / or if the UE supports PF bundling configuration (i.e., second paging configuration):

[0334] The PF and PO used for paging are determined by the following formula (by the UE and the base station, such as gNB):

[0335] The SFN of PF is determined by the following formula:

[0336] (SFN + offset) mod T = 0 or SFN mod T = offset, or

[0337] SFN mod T = 0.

[0338] The index (i_s) indicating the index of the PO is determined by the following formula:

[0339] i_s=UE_ID mod Ns′.

[0340] T is the UE's DRX period. T can be a UE-specific DRX period that is a multiple of X; or T can be X; or T can be max (UE-specific DRX period and X); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0341] The PDCCH listening timing for paging is determined based on pagingSearchSpace′, firstPDCCH-MonitoringOccasionOfPO′, and nrofPDCCH-MonitoringOccasionPerSSB-InPO′ (if configured).

[0342] In one embodiment, `pagingSearchSpace'` can be the same as `pagingSearchSpace`. In one embodiment, if `pagingSearchSpace` is not configured, `pagingSearchSpace'` is used. In one embodiment, `firstPDCCH-MonitoringOccasionOfPO'` can be the same as `firstPDCCH-MonitoringOccasionOfPO`. In one embodiment, if `firstPDCCH-MonitoringOccasionOfPO'` is not configured, `firstPDCCH-MonitoringOccasionOfPO` is used. In one embodiment, if `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` is not configured, `nrofPDCCH-MonitoringOccasionPerSSB-InPO` can be used. In one embodiment, `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` can be the same as `nrofPDCCH-MonitoringOccasionPerSSB-InPO`. In one embodiment, `Ns'` can be the same as `Ns`. In one embodiment, if `Ns` is not configured, `Ns` can be used.

[0343] Otherwise (e.g., if network power saving mode is not activated, or if no instruction to use PF bundling configuration is received from the network, or if the UE does not support PF bundling configuration (i.e., second paging configuration)):

[0344] The PF and PO used for paging are determined by the following formula (by the UE and the base station, such as gNB):

[0345] The SFN of PF is determined by the following formula:

[0346] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N)

[0347] The index (i_s) indicating the index of the PO is determined by the following formula:

[0348] i_s = floor(UE_ID / N) mod Ns

[0349] The PDCCH listening timing used for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured).

[0350] The UE listens for paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI). The gNB sends paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI).

[0351] The UE can also indicate its ability to support PF / PO binding when it is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0352] although Figure 11 An example of a method 1100 for binding paging timing is shown, but it is possible to modify... Figure 11 Various changes were made. For example, although it is shown as a series of steps, Figure 11 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0353] In one embodiment, the UE and gNB are as follows: Figure 12 The PF / PO used for paging is determined as shown.

[0354] Figure 12 Another method 1200 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 12 The embodiments of the methods shown are for illustrative purposes only. Figure 12 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0355] exist Figure 12 In the example, the value of N is expanded to have increased intervals between PFs. To compensate for the decrease in the number of PFs over time, the number of POs per PF is increased.

[0356] exist Figure 12 In examples, such as Figure 1 UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0357] In step 1210, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE can receive the paging configuration from the camping cell, or the UE can receive the paging configuration from another cell. The paging configuration includes:

[0358] -Ns: Number of paging opportunities for PF

[0359] -N: Number of paging frames. N = T, T / 2, T / 4, T / 8, T / 16, etc.

[0360] - Scaling factor: X (e.g., 2, 4, 8, 16, etc.), where X is a positive integer.

[0361] -PF_Offset: Paging frame offset

[0362] -nrofPDCCH-MonitoringOccasionPerSSB-INPO: This can be used to signal in system information (e.g., SIB1).

[0363] -firstPDCCH-MonitoringOccasionOfPO: For paging in a BWP configured by initialDownlinkBWP, this can be signaled in system information (e.g., SIB1). For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0364] -pagingSearchSpace: The ID of the search space used for paging.

[0365] The configuration can be per BWP or per cell. Some parameters (such as Ns, N, PF_Offset, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0366] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0367] In step 1220, the SFN of PF is determined as follows:

[0368] (SFN+PF_offset)mod T = (T div N′) (UE_ID mod N′)

[0369] In step 1230, the index (i_s) indicating the index of PO is determined by the following formula:

[0370] i_s=floor(UE_ID / N′)mod Ns′, where:

[0371] In one embodiment, N′=N / X (or N′=N X, in this case, can be, for example, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. (other values ​​are not excluded).

[0372] In one embodiment, Ns′=Ns X (Alternatively, Ns′=Ns / X, in which case X can be, for example, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc., other values ​​are not excluded)

[0373] In one embodiment, the network can signal nAndPagingFrameOffset-V19xx as shown in Table 2 below.

[0374] [Table 2]

[0375]

[0376] The UE applies the value of N indicated by N′=nAndPagingFrameOffset-V19xx; the PF_offset indicated by nAndPagingFrameOffset-V19xx is also applied to determine the PF / PO. If nAndPagingFrameOffset-V19xx is configured, the UE ignores nAndPagingFrameOffset (without suffix). If nAndPagingFrameOffset-V19xx is not configured, the UE applies the N indicated by N′=nAndPagingFrameOffset (without suffix). In one embodiment, the network may signal N′, and N′ is applied to determine the PF / PO. The UE ignores the N configured by nAndPagingFrameOffset. If N′ is not configured, the UE applies the N indicated by N′=nAndPagingFrameOffset.

[0377] In one embodiment, the network can signal ns-v19xx. ns-v19xx indicates a large value (greater than 4) for Ns. The UE applies the value of Ns indicated by Ns′=ns-v19xx; if n-v19xx is configured, the UE ignores ns (without suffix). If ns-v19xx is not configured, the UE applies the value of Ns indicated by Ns′=ns (without suffix).

[0378] In one embodiment, the network may signal ns-v19xx but not nAndPagingFrameOffset-V19xx. In another embodiment, the network may signal nAndPagingFrameOffset-V19xx but not ns-v19xx.

[0379] T is the UE's DRX period. T can be a UE-specific DRX period; or T can be the maximum (UE-specific DRX period and default DRX period); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0380] At step 1240, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0381] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0382] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent as determined by ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO... The S+K] PDCCH monitoring times for paging correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0383] In step 1250, the UE listens for paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., the PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0384] In one embodiment, if the UE and the cell support LP WUS, a UE in RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit shared by all UEs exists in the PEI and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0385] If network power saving mode is activated, or if an instruction to use PF bundling configuration is received from the network and / or if the UE supports PF bundling configuration:

[0386] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0387] The SFN of PF is determined by the following formula:

[0388] (SFN+PF_offset)mod T = (T div N′) (UE_ID mod N′)

[0389] The index (i_s) indicating the index of the PO is determined by the following formula:

[0390] i_s=floor(UE_ID / N′)mod Ns′, where

[0391] In one embodiment, N′=N / X (alternatively, N′=N X, in this case, can be, for example, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc. (other values ​​are not excluded).

[0392] In one embodiment, Ns′=Ns X (Alternatively, Ns′=Ns / X, in which case X can be, for example, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc., other values ​​are not excluded)

[0393] In one embodiment, the network can signal nAndPagingFrameOffset-V19xx as shown in Table 3 below.

[0394] [Table 3]

[0395]

[0396] The UE applies the N value indicated by N′=nAndPagingFrameOffset-V19xx; the PF_offset indicated by nAndPagingFrameOffset-V19xx is also applied to determine the PF / PO. If nAndPagingFrameOffset-V19xx is configured, the UE ignores nAndPagingFrameOffset (without suffix). If nAndPagingFrameOffset-V19xx is not configured, the UE applies the N indicated by N′=nAndPagingFrameOffset (without suffix). In one embodiment, the network may signal N′, and N′ is applied to determine the PF / PO. The UE ignores the N configured by nAndPagingFrameOffset. If N′ is not configured, the UE applies the N indicated by N′=nAndPagingFrameOffset.

[0397] In one embodiment, the network can signal ns-v19xx. ns-v19xx indicates a large value of Ns (greater than 4). The UE applies Ns′=Ns value indicated by ns-v19xx. If n-v19xx is configured, the UE ignores ns (without suffix). If ns-v19xx is not configured, the UE applies Ns′=Ns (without suffix) indicating Ns.

[0398] In one embodiment, the network may signal ns-v19xx instead of signaling nAndPagingFrameOffset-V19xx. In another embodiment, the network may signal nAndPagingFrameOffset-V19xx but not ns-v19xx.

[0399] The PDCCH listening timing for paging is determined based on pagingSearchSpace′, firstPDCCH-MonitoringOccasionOfPO′, and nrofPDCCH-MonitoringOccasionPerSSB-InPO′ (if configured).

[0400] In one embodiment, `pagingSearchSpace'` can be the same as `pagingSearchSpace`. In one embodiment, if `pagingSearchSpace'` is not configured, then `pagingSearchSpace` is used. In one embodiment, `firstPDCCH-MonitoringOccasionOfPO'` can be the same as `firstPDCCH-MonitoringOccasionOfPO`. In one embodiment, if `firstPDCCH-MonitoringOccasionOfPO'` is not configured, then `firstPDCCH-MonitoringOccasionOfPO` is used. In one embodiment, if `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` is not configured, then `nrofPDCCH-MonitoringOccasionPerSSB-InPO` can be used. In one embodiment, `nrofPDCCH-MonitoringOccasionPerSSB-InPO'` can be the same as `nrofPDCCH-MonitoringOccasionPerSSB-InPO`. In one embodiment, `Ns'` can be the same as `Ns`. In one embodiment, if `Ns` is not configured, then `Ns` can be used.

[0401] Otherwise (e.g., if network power saving mode is not activated, or if no instruction to use PF bundling configuration is received from the network, or if the UE does not support PF bundling configuration):

[0402] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0403] The SFN of PF is determined by the following formula:

[0404] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N)

[0405] The index (i_s) indicating the index of the PO is determined by the following formula:

[0406] i_s = floor(UE_ID / N) mod Ns

[0407] The PDCCH listening timing used for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured).

[0408] The UE listens for paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI). The gNB sends paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI).

[0409] The UE can also indicate its ability to support PF / PO bundling or extended values ​​of N and / or Ns when the UE is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0410] although Figure 12 An example of a method 1200 for binding paging timing is shown, but it is possible to modify... Figure 12 Various changes were made. For example, although it is shown as a series of steps, Figure 12 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0411] In one embodiment, the UE and gNB are as follows: Figure 13 The PF / PO used for paging is determined as shown.

[0412] Figure 13 Another method 1300 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 13 The embodiments of the methods shown are for illustrative purposes only. Figure 13One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0413] exist Figure 13 In the example, the value of N is expanded to have the number of POs that increase with each PF.

[0414] exist Figure 13 In examples, such as Figure 1 UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0415] In step 1310, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE may receive the paging configuration from the camping cell, or the UE may receive the paging configuration from another cell. The paging configuration includes:

[0416] Ns′: Number of paging opportunities for PF

[0417] -N: The number of paging frames. N = T, T / 2, T / 4, T / 8, T / 16, etc. (In an embodiment, the network can set N such that N equals 1. For example, if T is 16 radio frames, N can be set to T / 16, such that N = T / 16 = 16 / 16 = 1; for example, if T is 8 radio frames, N can be set to T / 8, such that N = T / 8 = 8 / 8 = 1, and so on.)

[0418] -PF_Offset: Paging frame offset

[0419] -nrofPDCCH-MonitoringOccasionPerSSB-InPO. This can be signaled in system information (e.g., SIB1).

[0420] -firstPDCCH-MonitoringOccasionOfPO. For paging in a BWP configured by initialDownlinkBWP, this can be signaled in system information (e.g., SIB1). For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0421] -pagingSearchSpace: The ID of the search space used for paging.

[0422] The configuration can be per BWP or per cell. Some parameters (such as Ns′, N, PF_Offset, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0423] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0424] In step 1320, the SFN of PF is determined as follows:

[0425] (SFN+PF_offset)mod T = (T div N) (UE_ID mod N)

[0426] In step 1330, the index (i_s) indicating the index of PO is determined by the following formula:

[0427] i_s=floor(UE_ID / N)mod Ns′, where

[0428] In one embodiment, the network can signal a second configuration of Ns (e.g., ns-v19xx). The second configuration of Ns (e.g., ns-v19xx) can indicate a large value of Ns (greater than 4). The UE applies the Ns value indicated by the second configuration of Ns (e.g., ns-v19xx) where Ns′=Ns; if the second configuration of Ns (e.g., ns-v19xx) is configured, the UE ignores the first configuration of Ns (e.g., ns (without suffix) 0). If the second configuration of Ns (e.g., ns-v19xx) is not configured, the UE applies the Ns indicated by the first configuration of Ns (e.g., ns (without suffix)) where Ns′=Ns.

[0429] In an embodiment, if the UE supports Ns′:

[0430] i_s=floor(UE_ID / N)mod Ns′ or

[0431] (Alternatively) i_s = Ns + floor(UE_ID / N) mod Ns′ (In the embodiment, Ns′ can have the same value as Ns in this case)

[0432] (Alternatively) i_s = Ns + floor(UE_ID / N) mod(Ns′ – Ns)

[0433] otherwise:

[0434] i_s = floor(UE_ID / N) mod Ns

[0435] Ns′ = The value indicated by the second configuration of Ns (e.g., ns-v19xx (a value greater than 4)).

[0436] Ns = The value indicated by the first configuration of Ns (e.g., ns (without suffix)).

[0437] T is the UE's DRX period. T can be a UE-specific DRX period; or T can be the maximum (UE-specific DRX period and default DRX period); or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0438] At step 1340, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0439] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0440] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent as determined by ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO... The S+K] PDCCH monitoring times for paging correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0441] In step 1350, the UE listens for paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0442] In one embodiment, if the UE and the cell support LP WUS, a UE in the RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for a PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit in the PEI shared by all UEs is set to 1), then the UE subsequently listens for a determined PO (using MR) and receives the paging message.

[0443] The UE can also indicate its ability to support PF / PO bundling or extended values ​​of N and / or Ns when the UE is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0444] although Figure 13 An example of a method 1300 for binding paging timing is shown, but it is possible to modify... Figure 13 Various changes were made. For example, although it is shown as a series of steps, Figure 13 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0445] In one embodiment, the UE and gNB are as follows: Figure 14 The PF / PO used for paging is determined as shown.

[0446] Figure 14 Another method 1400 for binding paging timing is shown according to an embodiment of the present disclosure. Figure 14 The embodiments of the methods shown are for illustrative purposes only. Figure 14 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for binding paging timing may be used without departing from the scope of this disclosure.

[0447] exist Figure 14 In the example, the distribution factor (T div N) is removed from the PF determination.

[0448] exist Figure 14 In examples, such as Figure 1UE 116 is in RRC_IDLE / RRC_INACTIVE state. The UE is camped on a cell. The UE obtains system information for the cell it is camped on.

[0449] In step 1410, the UE receives a paging configuration for listening to paging from the camping cell. The paging configuration may be signaled by the camping cell in system information (e.g., SIB1). The UE may receive the paging configuration from the camping cell, or the UE may receive the paging configuration from another cell. The paging configuration includes:

[0450] -Ns: Number of paging opportunities for PF

[0451] -N: Number of paging frames

[0452] -PF_Offset: Paging frame offset

[0453] -nrofPDCCH-MonitoringOccasionPerSSB-InPO. This can be signaled in system information (e.g., SIB1).

[0454] -firstPDCCH-MonitoringOccasionOfPO. For paging in a BWP configured by initialDownlinkBWP, this can be signaled in system information (e.g., SIB1). For paging in DL BWPs other than those configured by initialDownlinkBWP, the parameter first-PDCCH-MonitoringOccasionOfPO is signaled in the corresponding BWP configuration.

[0455] -pagingSearchSpace: The ID of the search space used for paging.

[0456] The configuration can be per BWP or per cell. Some parameters (such as Ns, N, PF_Offset, and nrofPDCCH-MonitoringOccasionPerSSB-InPO) can be cell-specific, while firstPDCCH-MonitoringOccasionOfPO can be BWP-specific.

[0457] The PF and PO used for paging are determined by the UE and the base station, such as gNB, using the following formula (in the case of extended DRX periods, the UE can determine the PF only within the paging time window):

[0458] In step 1420, the SFN of PF is determined as follows:

[0459] (SFN+PF_offset) mod T = (UE_ID mod N).

[0460] In an alternative embodiment, if the 1-bit indicator is in the SI (e.g., the cluster's / bundled PF / PO is set to true), then the SFN of the PF is determined by the following formula:

[0461] (SFN+PF_offset) mod T=UE_ID mod N

[0462] Otherwise, the SFN of PF is determined by the following formula:

[0463] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0464] In an alternative embodiment, if NES mode is activated, the SFN of the PF is determined by the following formula:

[0465] (SFN+PF_Offset) mod T=UE_ID mod N.

[0466] Otherwise, the SFN of PF is determined by the following formula:

[0467] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0468] In step 1430, the index (i_s) indicating the index of PO is determined by the following formula:

[0469] i_s=floor(UE_ID / N)mod Ns, where

[0470] T is the UE's DRX cycle. T is the DRX cycle signaled in the SI; or T is the max (UE-specific DRX cycle and default DRX cycle), or T can be determined according to a specified scheme. UE_ID is 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0471] At step 1440, the PDCCH listening timing for paging is determined based on pagingSearchSpace, firstPDCCH-MonitoringOccasionOfPO, and nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured). When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH listening timing for paging is the same as that for RMSI.

[0472] When SearchSpaceId = 0 is configured for pagingSearchSpace, Ns′ is 1 or 2. For Ns = 1, there is only one PO, which starts from the first PDCCH listening time used for paging in the PF. For Ns = 2, the PO is in the first half-frame (i_s = 0) or the second half-frame (i_s = 1) of the PF.

[0473] When a SearchSpaceId other than 0 is configured for pagingSearchSpace, the UE listens to the (i_s+1)th PO. The PO is S The set of X consecutive PDCCH monitoring opportunities, where "S" is the number of SSBs actually sent as determined by ssb-PositionsInBurst in SIB1, and X is nrofPDCCH-MonitoringOccasionPerSSB-InPO (if configured), otherwise equal to 1. The [x]th PDCCH monitoring opportunity in the PO... The S+K] PDCCH monitoring times for paging correspond to the Kth transmitted SSB, where x = 0, 1, …, X-1, K = 1, 2, …, S. PDCCH monitoring times for paging that do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are numbered sequentially from zero, starting with the first PDCCH monitoring time in the PF. When a firstPDCCH-MonitoringOccasionOfPO exists, the starting PDCCH monitoring time number of the (i_s+1)th PO is the (i_s+1)th value of the firstPDCCH-MonitoringOccasionOfPO parameter. Otherwise, it is equal to i_s. S X. If X > 1, then when the UE detects a PDCCH transmission addressing P-RNTI within its PO, the UE does not need to listen to subsequent PDCCH listening opportunities for this PO.

[0474] In step 1450, the UE listens for paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. The gNB transmits paging (i.e., PDCCH addressed to the P-RNTI) in the determined PF / PO. If Early Paging Indication (PEI) is supported, the UE listens for PEI at the PEI timing corresponding to the determined PF / PO, and the gNB transmits PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for paging in its PO. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for paging in its PO.

[0475] In one embodiment, if the UE and the cell support LP WUS, a UE in the RRC_IDLE or RRC_INACTIVE state can use LR to listen for a low-power wake-up signal (LP WUS). The gNB sends a low-power wake-up signal when it needs to transmit a RAN paging or CN paging to the UE or an SI / emergency notification to the UE. If an LP WUS is received (or an LP WUS for a UE / UE-specific paging subgroup is received), the UE listens for a PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if no supported paging subgroup exists in the cell, a bit in the PEI shared by all UEs is set to 1), then the UE subsequently listens for a determined PO (using MR) and receives the paging message.

[0476] The UE can also indicate its ability to support PF / PO bundling or extended values ​​of N and / or Ns when the UE is in the RRC_CONNECTED state. The CN / AMF can transmit this to the gNB for idle / inactive UEs to help the gNB determine the PF / PO.

[0477] although Figure 14 An example of a method 1400 for binding paging timing is shown, but it is possible to modify... Figure 14 Various changes were made. For example, although it is shown as a series of steps, Figure 14 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0478] Figure 15 A method 1500 for paging a UE according to an embodiment of the present disclosure is shown. Figure 15 The embodiments of the methods shown are for illustrative purposes only. Figure 15 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0479] exist Figure 15 In the example, the method begins at step 1510. At step 1510, the network element (e.g., a base station or gNB) determines N (the number of paging frames) and W (the scaling factor) based on SSB periodicity and pagingSearchSpace.

[0480] If the SSB periodicity > 160ms and the pagingSearchSpace is zero (alternatively, if the SSB periodicity > 160ms and the pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3): 1) The network element (e.g., a base station or gNB) sets parameter N to oneSixteenthT (i.e., nAndPagingFrameOffset is set to oneSixteenthT). 2) The network element (e.g., a base station or gNB) signals the scaling factor “W”. W is set to one of 1 / 2, 1 / 4, 1 / 8, etc., based on the SSB periodicity; if the SSB periodicity is 320ms, W is set to 1 / 2; if the SSB periodicity is 640ms, W is set to 1 / 4, etc.; in one embodiment, W is set to 160 / SSB periodicity. 3) The SSB periodicity may be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0481] If SSB periodicity is <= 160ms and pagingSearchSpace is zero:

[0482] If the SS / PBCH block and CORESET multiplexing pattern are 2 or 3, then for a 5 or 10 ms SSB periodicity, N can be set to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}. For a 20 ms SSB periodicity, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. For a 40 ms SSB periodicity, N can be set to one of {quartT, oneEighthT, oneSixteenthT}. For an 80 ms SSB periodicity, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms SSB periodicity, N can be set to oneSixteenthT.

[0483] If the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. Network elements (e.g., base stations or gNBs) can skip signaling "W", or "W" can be set to 1. SSB periodicity can be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0484] At step 1520, network elements (e.g., base stations or gNBs) may signal N, W, and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.). Signaling may be via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0485] At step 1530, a network element (e.g., a base station or gNB) determines the PF / PO for paging the UE. If paging for the UE exists, the network determines the PF / PO for paging the UE as follows:

[0486] If SSB periodicity > 160ms and pagingSearchSpace is zero (alternatively, if SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (alternatively, if "W" is signaled / configured):

[0487] A PF is a radio frame (SFN) that satisfies the following equation:

[0488] (SFN+PF_Offset) mod T = (T div (N W)) (UE_ID mod(N) W).

[0489] The index (i_s) indicating the index of the PO is determined by the following formula: i_s = floor(UE_ID / (N W))mod Ns.

[0490] Otherwise, PF is a radio frame (SFN) that satisfies the following equation:

[0491] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0492] The index (i_s) indicating the index of the PO is determined by the following formula:

[0493] i_s=floor(UE_ID / N) mod Ns.

[0494] Alternatively, if paging for the UE exists, the network element determines the PF / PO for paging the UE as follows:

[0495] A PF is a radio frame (SFN) that satisfies the following equation:

[0496] (SFN+PF_Offset) mod T = (T div (N W)) (UE_ID mod(N) W).

[0497] The index (i_s) indicating the index of the PO is determined by the following formula:

[0498] i_s=floor(UE_ID / (N) W))mod Ns.

[0499] If no signal notification / configuration is used, W equals 1.

[0500] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0501] At step 1540, the network element (e.g., a base station or gNB) sends a paging (i.e., a PDCCH addressed to the P-RNTI) in the determined PF / PO.

[0502] In step 1550, if early paging indication (PEI) is supported, the network element (i.e., the base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0503] At step 1560, if the UE and the network support low-power wake-up signals, the network element (e.g., a base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0504] although Figure 15 An example of a method 1500 for paging a UE is shown, but it is possible to modify it further. Figure 15 Various changes were made. For example, although it is shown as a series of steps, Figure 15 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0505] Figure 16 A method 1600 for receiving a paging is shown according to an embodiment of the present disclosure. Figure 16 The embodiments of the methods shown are for illustrative purposes only. Figure 16 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for receiving paging may be used without departing from the scope of this disclosure.

[0506] exist Figure 16 In the example, the method begins at step 1610. At step 1610, the UE may receive N, W, and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, PF_Offset, SSB periodicity, etc.) from network elements (e.g., base stations or gNBs). These may be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0507] In step 1620, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0508] If SSB periodicity > 160ms and pagingSearchSpace is zero (alternatively, if SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (alternatively, if "W" is signaled / configured):

[0509] A PF is a radio frame (SFN) that satisfies the following equation:

[0510] (SFN+PF_Offset) mod T = (T div (N W)) (UE_ID mod(N) W).

[0511] The index (i_s) indicating the index of the PO is determined by the following formula:

[0512] i_s=floor(UE_ID / (N) W))mod Ns.

[0513] Otherwise, PF is a radio frame (SFN) that satisfies the following equation:

[0514] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0515] The index (i_s) indicating the index of the PO is determined by the following formula:

[0516] i_s=floor(UE_ID / N) mod Ns.

[0517] Alternatively, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0518] A PF is a radio frame (SFN) that satisfies the following equation:

[0519] (SFN+PF_Offset) mod T = (T div (N W)) (UE_ID mod(N) W).

[0520] The index (i_s) indicating the index of the PO is determined by the following formula:

[0521] i_s=floor(UE_ID / (N) W))mod Ns

[0522] If no signal notification / configuration is used, W equals 1.

[0523] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0524] In step 1630, the UE listens for paging in the determined PF / PO (i.e., PDCCH addressed to P-RNTI).

[0525] In step 1640, if Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0526] At step 1650, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for the UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for the UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0527] although Figure 16 An example of a method 1600 for receiving paging is shown, but it is possible to modify it further. Figure 16 Various changes were made. For example, although it is shown as a series of steps, Figure 16 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0528] Figure 17 Another method 1700 for paging a UE according to an embodiment of the present disclosure is shown. Figure 17 The embodiments of the methods shown are for illustrative purposes only. Figure 17 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0529] exist Figure 17 In the example, the method begins at step 1710. At step 1710, the network element (e.g., a base station or gNB) determines N (the number of paging frames) and W (the scaling factor) based on the SSB periodicity and pagingSearchSpace.

[0530] If the SSB periodicity > 160 ms and the pagingSearchSpace is zero (or alternatively, if the SSB periodicity > 160 ms and the pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3), the network element (e.g., a base station or gNB) sets parameter N to oneSixteenthT (i.e., nAndPagingFrameOffset is set to oneSixteenthT). The network element (e.g., a base station or gNB) signals the scaling factor "W". W is set to one of 2, 4, 8, ..., etc., based on the SSB periodicity. If the SSB periodicity is 320 ms, W is set to 2; if the SSB periodicity is 640 ms, W is set to 4, and so on. In one embodiment, W is set to SSB periodicity / 160. The SSB periodicity may be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0531] If SSB periodicity is <= 160ms and pagingSearchSpace is zero:

[0532] If the SS / PBCH block and CORESET multiplexing pattern are 2 or 3, then for a 5 or 10 ms SSB periodicity, N can be set to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}. For a 20 ms SSB periodicity, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. For a 40 ms SSB periodicity, N can be set to one of {quartT, oneEighthT, oneSixteenthT}. For an 80 ms SSB periodicity, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms SSB periodicity, N can be set to oneSixteenthT.

[0533] If the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}.

[0534] Network elements can skip notifying "W" with a signal, or they can set "W" to 1.

[0535] SSB periodicity can be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0536] At step 1720, network elements (e.g., base stations or gNBs) may signal N, W, and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.). Signaling may be delivered via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0537] At step 1730, the network element (e.g., a base station or gNB) determines the PF / PO for paging the UE based on the configuration as follows.

[0538] If SSB periodicity > 160ms and pagingSearchSpace is zero (alternatively, if SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (alternatively, if "W" is signaled / configured):

[0539] A PF is a radio frame (SFN) that satisfies the following equation:

[0540] (SFN+PF_Offset) mod T = (T div (N / W)) (UE_ID mod(N / W)).

[0541] The index (i_s) indicating the index of the PO is determined by the following formula:

[0542] i_s=floor(UE_ID / (N / W)) mod Ns.

[0543] Otherwise, PF is a radio frame (SFN) that satisfies the following equation:

[0544] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0545] The index (i_s) indicating the index of the PO is determined by the following formula:

[0546] i_s=floor(UE_ID / N) mod Ns.

[0547] Alternatively, if paging for the UE exists, the network element determines the PF / PO for paging the UE as follows:

[0548] A PF is a radio frame (SFN) that satisfies the following equation:

[0549] (SFN+PF_Offset) mod T = (T div (N / W)) (UE_ID mod(N / W)).

[0550] The index (i_s) indicating the index of the PO is determined by the following formula:

[0551] i_s=floor(UE_ID / (N / W)) mod Ns.

[0552] If no signal notification / configuration is used, W equals 1.

[0553] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0554] At step 1740, the network element (e.g., a base station or gNB) sends a paging (i.e., a PDCCH addressed to the P-RNTI) in the determined PF / PO.

[0555] In step 1750, if Early Paging Indication (PEI) is supported, the network element (e.g., a base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0556] At step 1760, if the UE and the network support low-power wake-up signals, the network element (e.g., a base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0557] although Figure 17 An example of method 1700 for paging a UE is shown, but it is possible to modify... Figure 17 Various changes were made. For example, although it is shown as a series of steps, Figure 17 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0558] Figure 18 Another method 1800 for receiving a paging is shown according to an embodiment of the present disclosure. Figure 18 The embodiments of the methods shown are for illustrative purposes only. Figure 18 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for receiving paging may be used without departing from the scope of this disclosure.

[0559] exist Figure 18 In the example, the method begins at step 1810. At step 1810, the UE may receive N, W, and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, PF_Offset, SSB periodicity, etc.) from network elements (e.g., base stations or gNBs). These may be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0560] In step 1820, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0561] If SSB periodicity > 160ms and pagingSearchSpace is zero (alternatively, if SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (alternatively, if "W" is signaled / configured):

[0562] A PF is a radio frame (SFN) that satisfies the following equation:

[0563] (SFN+PF_Offset) mod T = (T div (N / W)) (UE_ID mod(N / W)).

[0564] The index (i_s) indicating the index of the PO is determined by the following formula:

[0565] i_s=floor(UE_ID / (N / W)) mod Ns.

[0566] Otherwise, PF is a radio frame (SFN) that satisfies the following equation:

[0567] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0568] The index (i_s) indicating the index of the PO is determined by the following formula:

[0569] i_s=floor(UE_ID / N) mod Ns.

[0570] Alternatively, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0571] A PF is a radio frame (SFN) that satisfies the following equation:

[0572] (SFN+PF_Offset) mod T = (T div (N / W)) (UE_ID mod(N / W)).

[0573] The index (i_s) indicating the index of the PO is determined by the following formula:

[0574] i_s=floor(UE_ID / (N / W)) mod Ns.

[0575] If no signal notification / configuration is used, W equals 1.

[0576] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0577] In step 1830, the UE listens for paging in the determined PF / PO (i.e., PDCCH addressed to P-RNTI).

[0578] In step 1840, if Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0579] In step 1850, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for the UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for the UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0580] although Figure 18 An example of a method 1800 for receiving a paging message is shown, but it is possible to modify it further. Figure 18 Various changes were made. For example, although it is shown as a series of steps, Figure 18The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0581] Figure 19 Another method 1900 for paging a UE according to an embodiment of the present disclosure is shown. Figure 19 The embodiments of the methods shown are for illustrative purposes only. Figure 19 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0582] exist Figure 19 In the example, the method begins at step 1910. At step 1910, the network element (e.g., a base station or gNB) determines N (the number of paging frames) based on SSB periodicity and pagingSearchSpace.

[0583] If the SSB periodicity > 160ms and the pagingSearchSpace is zero (or alternatively, if the SSB periodicity > 160ms and the pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3), the network element (i.e., the base station or gNB) sets parameter N to oneSixteenthT (i.e., nAndPagingFrameOffset is set to oneSixteenthT). The network element also sets the paging frame offset. The SSB periodicity can be indicated by the field ssb-periodicityServingCell in the system information (e.g., SIB1 or SIB).

[0584] If SSB periodicity is <= 160ms and pagingSearchSpace is zero:

[0585] If the SS / PBCH block and CORESET multiplexing pattern are 2 or 3, then for a 5 or 10 ms SSB periodicity, N can be set to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}. For a 20 ms SSB periodicity, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. For a 40 ms SSB periodicity, N can be set to one of {quarterT, oneEighthT, oneSixteenthT}. For an 80 ms SSB periodicity, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms SSB periodicity, N can be set to oneSixteenthT.

[0586] If the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}.

[0587] SSB periodicity can be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0588] At step 1920, network elements (e.g., base stations or gNBs) can signal N and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.). Signaling can be delivered via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0589] At step 1930, the network element (e.g., a base station or gNB) determines the PF / PO for paging the UE in the following manner.

[0590] If the SSB periodicity > 160ms and the pagingSearchSpace is zero (alternatively, if the SSB periodicity > 160ms and the pagingSearchSpace is zero and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3), then N = T / SSB periodicity is used to determine PF and PO. N, signaled by the configuration via nAndPagingFrameOffset, is not used. PF_Offset, signaled by the configuration via nAndPagingFrameOffsetPF, is used to determine PF (alternatively, PF_Offset = offset from SFN 0 to the start of the SSB burst is used).

[0591] Otherwise, use the N and PF_Offset signals notified via the configuration of nAndPagingFrameOffset.

[0592] A PF is a radio frame (SFN) that satisfies the following equation:

[0593] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0594] The index (i_s) indicating the index of the PO is determined by the following formula:

[0595] i_s = floor(UE_ID / N) mod Ns

[0596] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0597] At step 1940, the network element (e.g., a base station or gNB) sends a paging (i.e., a PDCCH addressed to the P-RNTI) in the determined PF / PO.

[0598] In step 1950, if early paging indication (PEI) is supported, the network element (e.g., base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0599] At step 1960, if the UE and the network support low-power wake-up signals, the network element (e.g., a base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0601] Figure 20 Another method 2000 for receiving a paging is shown according to an embodiment of the present disclosure. Figure 20 The embodiments of the methods shown are for illustrative purposes only. Figure 20One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for receiving paging may be used without departing from the scope of this disclosure.

[0602] exist Figure 20 In the example, the method begins at step 2010. At step 2010, the UE may receive N and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, PF_Offset, SSB periodicity, etc.) from network elements (e.g., base stations or gNBs). These may be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0603] In step 2020, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0604] If the SSB periodicity > 160ms and the pagingSearchSpace is zero (alternatively, if the SSB periodicity > 160ms and the pagingSearchSpace is zero and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3), then N = T / SSB periodicity is used to determine PF and PO. N, signaled by the configuration via nAndPagingFrameOffset, is not used. PF_Offset, signaled by the configuration via nAndPagingFrameOffsetPF, is used to determine PF (alternatively, PF_Offset = offset from SFN 0 to the start of the SSB burst is used).

[0605] Otherwise, use the N and PF_Offset signals notified via the configuration of nAndPagingFrameOffset.

[0606] A PF is a radio frame (SFN) that satisfies the following equation:

[0607] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N)

[0608] The index (i_s) indicating the index of the PO is determined by the following formula:

[0609] i_s=floor(UE_ID / N) mod Ns.

[0610] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0611] In step 2030, the UE listens for paging in the determined PF / PO (i.e., PDCCH addressed to P-RNTI).

[0612] In step 2040, if Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0613] In step 2050, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for the UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for the UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

Figure 21 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0616] exist Figure 21 In the example, the method begins at step 2110. At step 2110, a network element (e.g., a base station or gNB) signals nAndPagingFrameOffset and / or nAndPagingFrameOffset-V19xx, along with other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.). The signaling can be via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0617] If the SSB periodicity is > 160ms and the pagingSearchSpace is zero (alternatively, if the SSB periodicity is > 160ms and the pagingSearchSpace is zero and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (alternatively, if the SSB periodicity is > 160ms), then N is set to T / SSB periodicity. The network notifies N and PF_Offset by signaling the parameter nAndPagingFrameOffset-V19xx in the paging configuration, as shown in Table 4 below.

[0618] [Table 4]

[0619]

[0620] If the SSB period is 320ms, then N is set to oneThirtytwothT; if the SSB period is 640ms, then N is set to oneSixtyFourthT; if the SSB period is 1280ms, then N is set to oneOneTwentyeighthT; and so on.

[0621] If SSB periodicity is <= 160ms and pagingSearchSpace is zero:

For a 20 ms SSB periodicity, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. For a 40 ms SSB periodicity, N can be set to one of {quartT, oneEighthT, oneSixteenthT}. For an 80 ms SSB periodicity, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms SSB periodicity, N can be set to oneSixteenthT.

[0623] If the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}.

[0624] Network elements signal N and PF_Offset by including the parameter nAndPagingFrameOffset in the paging configuration, as shown in Table 5 below.

[0625] [Table 5]

[0630] At step 2120, the network element (e.g., a base station or gNB) determines the PF / PO for paging the UE in the following manner.

[0631] If nAndPagingFrameOffset-V19xx is signaled, then N and PF_Offset as indicated by nAndPagingFrameOffset-V19xx are used. N and PF_Offset as indicated by nAndPagingFrameOffset are ignored.

At step 2210, the UE receives nAndPagingFrameOffset and / or nAndPagingFrameOffset-V19xx and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.) from a network element (e.g., a base station or gNB). These can be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0644] In step 2220, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0645] If nAndPagingFrameOffset-V19xx is signaled, then N and PF_Offset as indicated by nAndPagingFrameOffset-V19xx are used. N and PF_Offset as indicated by nAndPagingFrameOffset are ignored.

[0649] The index (i_s) indicating the index of the PO is determined by the following formula:

[0650] i_s=floor(UE_ID / N) mod Ns.

[0651] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0654] In step 2250, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for a UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0655] although Figure 22 An example of a method 2200 for receiving a paging message is shown, but other methods are possible. Figure 22 Various changes were made. For example, although it is shown as a series of steps, Figure 22 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0656] Figure 23 Another method 2300 for paging a UE according to an embodiment of the present disclosure is shown. Figure 23 The embodiments of the methods shown are for illustrative purposes only. Figure 23 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0657] exist Figure 23In the example, the method begins at step 2310. At step 2310, the network element (e.g., a base station or gNB) signals nAndPagingFrameOffset and / or nAndPagingFrameOffset-V19xx, along with other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.). The signaling can be via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages as shown in Table 7.

[0658] [Table 7]

[0659]

[0660] At step 2330, the network element (e.g., a base station or gNB) determines the PF / PO for paging the UE as follows:

[0661] If the network is sending an SSB based on an SSB periodicity > 160ms (or alternatively, if the network is sending an SSB based on an SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (or alternatively, if the network is sending an SSB based on an SSB periodicity > 160ms and pagingSearchSpace is zero), then the PF / PO is determined using N and PF_Offset indicated by nAndPagingFrameOffset-V19xx.

[0662] Otherwise, N and PF_Offset, indicated by nAndPagingFrameOffset, are used to determine PF / PO.

[0663] A PF is a radio frame (SFN) that satisfies the following equation:

[0664] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0665] The index (i_s) indicating the index of the PO is determined by the following formula:

[0666] i_s = floor(UE_ID / N) mod Ns

[0667] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0668] In step 2330, the network element (e.g., a base station or gNB) sends a paging (i.e., a PDCCH addressed to the P-RNTI) in the determined PF / PO.

[0669] In step 2340, if Early Paging Indication (PEI) is supported, the network element (e.g., a base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0670] In step 2350, if the UE and the network support low-power wake-up signals, the network element (i.e., the base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0671] In one embodiment, network elements can signal two SSB periods: a short SSB period and a longer SSB period. The N and PF_Offset corresponding to each of these SSB periods can be signaled separately. If not signaled, the UE / gNB applies the same N and PF_Offset to both SSB periods. The SSB periods can be dynamically updated between the shorter and longer periods, and the network entity indicates (e.g., using PDCCH, short messages, paging messages, paging DCI, or system information) which of the two SSB periods to apply. In one embodiment, upon receiving an indication to change the SSB period, the changed period and the corresponding configuration of N and PF_offset are applied from the current DRX period / default DRX period, or from the next DRX period / default DRX period, or from the specified DRX period / default DRX period. In another embodiment, upon receiving an indication to change the SSB period, the changed period and the corresponding configuration of N and PF_offset are applied from the end of the SSB period corresponding to the current SSB period. In one embodiment, upon receiving an SSB periodicity change indication, an SSB based on the changed SSB periodicity is sent after the end of the SSB period corresponding to the previous SSB periodicity. In another embodiment, upon receiving an SSB periodicity change indication, an SSB is sent during the SSB timing based on the changed SSB periodicity.

[0672] although Figure 23 An example of a method 2300 for paging a UE is shown, but it is possible to modify it further. Figure 23 Various changes were made. For example, although it is shown as a series of steps, Figure 23 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0673] Figure 24Another method 2400 for receiving a paging is shown according to an embodiment of the present disclosure. Figure 24 The embodiments of the methods shown are for illustrative purposes only. Figure 24 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for receiving paging may be used without departing from the scope of this disclosure.

[0674] exist Figure 24 In the example, the method begins at step 2410. At step 2410, the UE may receive nAndPagingFrameOffset and / or nAndPagingFrameOffset-V19xx and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.) from the network entity (i.e., the base station or gNB). These may be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0675] In step 2420, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0676] If the network is sending an SSB based on an SSB periodicity > 160ms (or alternatively, if the network is sending an SSB based on an SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3) (or alternatively, if the network is sending an SSB based on an SSB periodicity > 160ms and pagingSearchSpace is zero), then the PF / PO is determined using N and PF_Offset indicated by nAndPagingFrameOffset-V19xx.

[0677] Otherwise, N and PF_Offset, indicated by nAndPagingFrameOffset, are used to determine PF / PO.

[0678] A PF is a radio frame (SFN) that satisfies the following equation:

[0679] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0680] The index (i_s) indicating the index of the PO is determined by the following formula:

[0681] i_s=floor(UE_ID / N) mod Ns.

[0682] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0683] In step 2430, the UE listens for paging in the determined PF / PO (i.e., PDCCH addressed to P-RNTI).

[0684] In step 2440, if Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0685] In step 2450, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for a UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0686] although Figure 24 An example of a method 2400 for receiving paging is shown, but more can be found elsewhere. Figure 24 Various changes were made. For example, although it is shown as a series of steps, Figure 24 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0687] Figure 25 Another method 2500 for paging a UE according to an embodiment of the present disclosure is shown. Figure 25 The embodiments of the methods shown are for illustrative purposes only. Figure 25One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for paging UEs may be used without departing from the scope of this disclosure.

[0688] exist Figure 25 In the example, the method begins at step 2510. At step 2510, a network element (e.g., a base station or gNB) signals the first SSB periodicity and the second SSB periodicity. The network element (e.g., a base station or gNB) signals the first and second configurations of the N and PF offsets. The first configuration of the N and PF offsets corresponds to the first SSB periodicity. The second configuration of the N and PF offsets corresponds to the second SSB periodicity. The configurations of the N and PF offsets can be signaled using nAndPagingFrameOffset or nAndPagingFrameOffset-V19xx. Signaling can be via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0689] At step 2520, the network element (e.g., a base station or gNB) determines the PF / PO for paging the UE as follows:

[0690] If the SSB periodicity on which the network is sending the SSB is the first SSB periodicity, then the first configuration of N and PF offset is used to determine PF / PO.

[0691] Otherwise, if the SSB periodicity on which the network is sending the SSB is based is the second SSB periodicity, then the second configuration of N and PF offset is used to determine PF / PO.

[0692] A PF is a radio frame (SFN) that satisfies the following equation:

[0693] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N)

[0694] The index (i_s) indicating the index of the PO is determined by the following formula:

[0695] i_s=floor(UE_ID / N) mod Ns.

[0696] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0697] In step 2530, the network element (e.g., a base station or gNB) sends a paging (i.e., a PDCCH addressed to the P-RNTI) in the determined PF / PO.

[0698] In step 2540, if Early Paging Indication (PEI) is supported, the network element (e.g., a base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0699] At step 2550, if the UE and the network support low-power wake-up signals, the network element (e.g., a base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0700] although Figure 25 An example of a method 2500 for paging a UE is shown, but it is possible to modify it further. Figure 25 Various changes were made. For example, although it is shown as a series of steps, Figure 25 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0701] Figure 26 Another method 2600 for receiving a paging is shown according to an embodiment of the present disclosure. Figure 26 The embodiments of the methods shown are for illustrative purposes only. Figure 26 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments for receiving paging may be used without departing from the scope of this disclosure.

[0702] exist Figure 26 In the example, the method begins at step 2610. At step 2610, the UE receives a first SSB periodicity and a second SSB periodicity from a network element (e.g., a base station or gNB). The UE receives a first configuration and a second configuration of N and PF offsets from the network element (e.g., a base station or gNB). The first configuration of N and PF offsets corresponds to the first SSB periodicity. The second configuration of N and PF offsets corresponds to the second SSB periodicity. The configuration of N and PF offsets can be signaled using nAndPagingFrameOffset or nAndPagingFrameOffset-V19xx. These can be received in system information (such as SIB or SIB1), or RRC messages, SI messages, or any other messages.

[0703] In step 2620, the UE determines the PF / PO for receiving paging based on the received configuration, as follows:

[0704] If the SSB periodicity on which the network is sending the SSB is the first SSB periodicity, then the first configuration of N and PF offset is used to determine PF / PO.

[0705] Otherwise, if the SSB periodicity on which the network is sending the SSB is based is the second SSB periodicity, then the second configuration of N and PF offset is used to determine PF / PO.

[0706] A PF is a radio frame (SFN) that satisfies the following equation:

[0707] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0708] The index (i_s) indicating the index of the PO is determined by the following formula:

[0709] i_s = floor(UE_ID / N) mod Ns

[0710] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0711] In step 2630, the UE listens for paging in the determined PF / PO (i.e., PDCCH addressed to P-RNTI).

[0712] In step 2640, if Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the subgroup to which the UE belongs is paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0713] In step 2650, if the UE and the network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS is received for a UE / UE-specific paging subgroup), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for a UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0714] although Figure 26 An example of a method 2600 for receiving paging is shown, but it is possible to modify it further. Figure 26 Various changes were made. For example, although it is shown as a series of steps, Figure 26 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0715] In one embodiment, a network element (e.g., a base station or gNB) determines the pagingSearchSpace based on the SSB periodicity. If the SSB periodicity > 160 ms, the network element (e.g., the base station or gNB) sets the pagingSearchSpace to non-zero; otherwise, it can be set to zero or non-zero. Alternatively, if the SSB periodicity > 160 ms and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3, the network element (e.g., the base station or gNB) sets the pagingSearchSpace to non-zero. The network element (e.g., the base station or gNB) signals the determined pagingSearchSpace. The signaling can be via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0716] In another embodiment, a network element (e.g., a base station or gNB) signals a first SSB periodicity and a second SSB periodicity. The first SSB periodicity is > 160 ms, and the second SSB periodicity is <= 160 ms. The network element (e.g., a base station or gNB) signals a first paging search space identifier and a second paging search space identifier. The first paging search space identifier indicates a paging search space corresponding to the first SSB periodicity. The second paging search space identifier indicates a paging search space corresponding to the second SSB periodicity. In one embodiment, the first paging search space identifier may be set to a non-zero value, and the second paging search space identifier may be set to zero or a non-zero value. In another embodiment, both the first and second paging search space identifiers may be set to zero or a non-zero value. If one of the paging search space identifiers is not signaled, the other paging search space identifier is applied to both the first and second SSB periodicities.

[0717] The SSB periodicity can be dynamically updated between the first and second SSB periodicities, and the network indicates which of the two SSB periodicities to apply. In one embodiment, upon receiving an indication to change the SSB periodicity, the changed periodicity and corresponding paging search space configuration are applied from the current DRX / default DRX period, the next DRX / default DRX period, or the specified DRX / default DRX period. In another embodiment, upon receiving an indication to change the SSB periodicity, the changed periodicity and corresponding configuration are applied from the end of the SSB period corresponding to the current SSB periodicity. In one embodiment, upon receiving an SSB periodicity change indication, an SSB based on the changed SSB periodicity is transmitted after the end of the SSB period corresponding to the previous SSB periodicity. In yet another embodiment, upon receiving an SSB periodicity change indication, an SSB is transmitted during an SSB timing event based on the changed SSB periodicity. The UE and gNB apply a paging search space identifier corresponding to the SSB periodicity of the transmitted SSB to determine the PDCCH listening timing for paging.

[0718] In one embodiment, the network element used for paging (e.g., a base station or gNB) operates as follows:

[0719] Network elements (e.g., base stations or gNBs) determine N (the number of paging frames) based on SSB periodicity and pagingSearchSpace.

[0720] If the SSB periodicity is > 160ms and the pagingSearchSpace is zero (or alternatively, if the SSB periodicity is > 160ms and the pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3), then the network element (e.g., a base station or gNB) sets parameter N to oneSixteenthT (i.e., nAndPagingFrameOffset is set to oneSixteenthT). N is the number of paging frames. The SSB periodicity can be indicated by the field ssb-periodicityServingCell in the system information (e.g., SIB1 or SIB).

[0721] - If SSB periodicity <= 160ms and pagingSearchSpace is zero (alternatively, if SSB periodicity > 160ms and pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3):

[0722] If the SS / PBCH block and CORESET multiplexing pattern are 2 or 3, then for a 5 or 10 ms SSB periodicity, N can be set to one of {oneT, halfT, quarterT, oneEighthT, oneSixteenthT}. For a 20 ms SSB periodicity, N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}. For a 40 ms SSB periodicity, N can be set to one of {quartT, oneEighthT, oneSixteenthT}. For an 80 ms SSB periodicity, N can be set to one of {oneEighthT, oneSixteenthT}. For a 160 ms SSB periodicity, N can be set to oneSixteenthT.

[0723] If the SS / PBCH block and CORESET multiplexing pattern are 1, then N can be set to one of {halfT, quarterT, oneEighthT, oneSixteenthT}.

[0724] SSB periodicity can be indicated by the field ssb-periodicityServingCell in system information (e.g., SIB1 or SIB).

[0725] Network elements (e.g., base stations or gNBs) signal N and other paging configurations (such as pagingSearchSpace, Ns, default DRX cycle, etc.). Signaling can be delivered via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0726] Network elements (e.g., base stations or gNBs) determine the PF / PO used for paging.

[0727] If the SSB periodicity is > 160ms and the pagingSearchSpace is zero (alternatively, if the SSB periodicity is > 160ms and the pagingSearchSpace is zero, and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3), then the network element (e.g., a base station or gNB) determines N and PF_Offset according to the nAndPagingFrameOffset configuration. Alternatively, the network element (i.e., the base station or gNB) determines N according to the nAndPagingFrameOffset configuration. PF Offset = Offset from SFN 0 to the start of the SSB burst.

[0728] Otherwise, network elements (e.g., base stations or gNBs) determine N and PF_Offset from the configuration of nAndPagingFrameOffset.

[0729] If the paging search space is zero (or if the paging search space is zero and the SS / PBCH block and CORESET multiplexing pattern is 2 or 3), and if the SSB periodicity is > 160ms, then in order to determine the PDCCH listening timing for paging, the network entity (i.e., the base station or gNB) assumes that the SSB periodicity is 160ms.

[0730] A PF is a radio frame (SFN) that satisfies the following equation:

[0731] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0732] The index (i_s) indicating the index of the PO is determined by the following formula:

[0733] i_s = floor(UE_ID / N) mod Ns

[0734] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0735] Network entities (e.g., base stations or gNBs) send paging (i.e., PDCCH addressed to P-RNTI) in the determined PF / PO.

[0736] In the case of supporting Early Paging Indication (PEI), the network entity (i.e., the base station or gNB) sends the PEI at the PEI timing corresponding to the determined PF / PO.

[0737] If the UE and the network support low-power wake-up signals, the network entity (i.e., the base station or gNB) sends a low-power wake-up signal before the determined PEI timing or before the determined PF / PO timing.

[0738] In one embodiment of this disclosure, the UE operation for paging is as follows:

[0739] The UE receives N and other paging configurations (such as pagingSearchSpace, Ns, default DRX period, etc.) from network elements (e.g., base stations or gNBs). Signaling can be delivered via system information (such as SIB or SIB1), or RRC messages, SI messages, or any other message.

[0740] The UE determines the PF / PO used for paging.

[0741] If the SSB periodicity is > 160ms and the pagingSearchSpace is zero (or alternatively, if the SSB periodicity is > 160ms and the pagingSearchSpace is zero and if the SS / PBCH block and CORESET multiplexing pattern are 2 or 3), then the UE determines N and PF_Offset from the nAndPagingFrameOffset configuration. Alternatively, the UE determines N from the nAndPagingFrameOffset configuration. PF Offset = Offset from SFN 0 to the start of the SSB burst.

[0742] Otherwise, the UE determines N and PF_Offset from the configuration of nAndPagingFrameOffset.

[0743] If the paging search space is zero (or if the paging search space is zero and if the SS / PBCH block and CORESET multiplexing pattern is 2 or 3), and if the SSB periodicity is > 160ms, then in order to determine the PDCCH listening timing for paging, the UE assumes that the SSB periodicity is 160ms.

[0744] A PF is a radio frame (SFN) that satisfies the following equation:

[0745] (SFN+PF_Offset) mod T = (T div N) (UE_ID mod N).

[0746] The index (i_s) indicating the index of the PO is determined by the following formula:

[0747] i_s=floor(UE_ID / N) mod Ns.

[0748] UE_ID can be 5G-S-TMSI mod Y, where Y can be 1024, 2048, 4096, 8192, 16384, etc.

[0749] The UE listens for paging in the determined PF / PO (i.e., the PDCCH addressed to the P-RNTI).

[0750] When Early Paging Indication (PEI) is supported, the UE listens for the PEI at the PEI timing corresponding to the determined PF / PO. If the UE's subgroup is being paged as indicated by the associated PEI (Early Paging Indication), the UE should listen for the PDCCH in its PO for the paging. If the UE cannot find its subgroup ID using the PEI configuration in the cell, or if the UE cannot listen for the associated PEI timing corresponding to its PO, it should listen for the paging in its PO.

[0751] If the UE and network support low-power wake-up signals, the UE listens for the LP WUS before the determined PEI timing or before the determined PF / PO. If the LP WUS is received (or if the LP WUS for the UE / UE-specific paging subgroup is received), the UE listens for the PEI (using MR) and / or if the PEI indicates paging for the UE / UE-specific paging subgroup (or the bit in the PEI corresponding to the UE's paging subgroup is set to 1, or if there is no supported paging subgroup in the cell, there is a bit in the PEI shared by all UEs and that bit is set to 1), then the UE subsequently listens for the determined PO (using MR) and receives the paging message.

[0752] Figure 27 A method 2700 for binding paging timing according to an embodiment of the present disclosure is shown. Figure 27 The embodiments of the methods shown are for illustrative purposes only. Figure 27 One or more components shown may be implemented in a dedicated circuit configured to perform the function, or one or more components may be implemented by one or more processors that execute instructions to perform the function. Other embodiments of bundled paging timing may be used without departing from the scope of this disclosure.

[0753] Method 2700 begins at step 2710. In step 2710, the UE (such as...) Figure 1UE 116 receives a first paging configuration. In step 2170, the UE receives a second paging configuration. In step 2730, the UE determines whether to apply the first or second paging configuration. In step 2740, the UE determines the PF based on the applied paging configuration. Finally, in step 2750, the UE determines the PO index based on the applied paging configuration.

[0754] although Figure 27 An example of method 2700 for binding paging timing is shown, but it is possible to modify... Figure 27 Various changes were made. For example, although it is shown as a series of steps, Figure 27 The steps in the process can overlap, appear in parallel, appear in different orders, appear any number of times, be omitted, or be replaced by other steps.

[0755] Figure 28 A block diagram of a terminal (or user equipment (UE)) according to an embodiment of the present disclosure is shown.

[0756] like Figure 28 As shown, the terminal according to the embodiment may include a transceiver 2810, a memory 2820, and a processor (or controller) 2830. The transceiver 2810, memory 2820, and processor (or controller) 2830 of the terminal can operate according to the communication method of the terminal described above. However, the components of the terminal are not limited thereto. For example, the terminal may include... Figure 28 The components described herein may include more or fewer components. Additionally, the processor (or controller) 2830, transceiver 2810, and memory 2820 may be implemented as a single chip. Furthermore, the processor (or controller) 2830 may include at least one processor.

[0757] Transceiver 2810 refers uniformly to a terminal station receiver and a terminal transmitter, and can transmit signals to or receive signals from a base station or another terminal. Signals transmitted to or received from a terminal may include control information and data. Transceiver 2810 may include an RF transmitter for up-converting and amplifying the frequency of the transmitted signal, and an RF receiver for amplifying the frequency of the received signal for low noise and down-conversion. However, this is only an example of transceiver 2810, and the components of transceiver 2810 are not limited to RF transmitters and RF receivers.

[0758] In addition, transceiver 2810 can receive signals via a wireless channel and output them to processor (or controller) 2830, and transmit signals output from processor (or controller) 2830 via a wireless channel.
