Abstract
Description
Technical Field
[0001] The present invention relates to wireless communications, and more particularly to apparatus, systems and methods for enhancing system information reading in non-terrestrial networks (NTNs), including systems, methods and mechanisms for determining the timing and / or opportunity for UEs to read system information and determining scheduling restrictions when system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above.
[0002] Related technical description
[0003] The use of wireless communication systems is growing rapidly. In recent years, wireless devices such as smart phones and tablet computers have become increasingly sophisticated. In addition to supporting phone calls, many mobile devices now also provide access to the Internet, email, text messaging, and navigation using the Global Positioning System (GPS), and are capable of operating sophisticated applications that utilize these functions.
[0004] Long Term Evolution (LTE) is currently the technology of choice for most wireless network operators around the world, providing mobile broadband data and high-speed Internet access to their subscriber base. LTE was first proposed in 2004 and first standardized in 2008. Since then, as the use of wireless communication systems has grown exponentially, the need for wireless network operators to support higher capacity for a higher density of mobile broadband users has also risen. As a result, research into new radio access technologies began in 2015, and in 2017, the first version of Fifth Generation New Radio (5G NR) was standardized.
[0005] 5G-NR (also referred to as NR) provides higher capacity for a higher density of mobile broadband users compared to LTE, while also supporting ultra-reliable and massive machine-type communications from device to device, as well as lower latency and / or lower battery consumption. In addition, NR may allow for more flexible UE scheduling compared to current LTE. Therefore, efforts are being made to continue the development of 5G-NR to take advantage of the higher throughput possible at higher frequencies. Summary of the invention
[0006] Embodiments relate to wireless communications, and more particularly to apparatus, systems, and methods for enhancing system information reading in NTNs, including systems, methods, and mechanisms for determining timing and / or opportunity for UEs to read system information and determining scheduling restrictions when system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above.
[0007] For example, in some embodiments, a user equipment device (UE) may be configured to determine that a triggering event for reading system information for satellite information has occurred. The triggering event for reading system information for satellite information may include at least one of the following: network behavior, UE behavior, channel condition, timing condition, distance condition, or network indication. The UE may be configured to read the system information of the satellite information based on the occurrence of the triggering event. The system information reading of the satellite information may include at least ephemeris information.
[0008] As another example, the UE may be configured to determine that a system information reading opportunity of satellite information conflicts with receiving a data channel or a control channel from a serving cell. The UE may be configured to prioritize the system information reading opportunity of satellite information over receiving a data channel. The UE may be configured to discard reception of a data channel.
[0009] As an additional example, the UE may be configured to determine that a system information reading opportunity for satellite information conflicts with an uplink transmission. The UE may be configured to prioritize the system information reading opportunity for satellite information over the uplink transmission. The UE may be configured to skip the uplink transmission.
[0010] As another example, the UE may be configured to determine that the system information reading opportunity of the satellite information conflicts with the uplink transmission. The UE may be configured to prioritize the uplink transmission over the system information reading opportunity of the satellite information. The UE may be configured to skip the system information reading opportunity of the satellite information.
[0011] As another example, the UE may be configured to determine that the system information reading opportunity of the satellite information conflicts with the uplink transmission. The UE may be configured to prioritize the uplink transmission over the system information reading opportunity of the satellite information based on determining that the uplink transmission is a non-periodic uplink transmission. The UE may be configured to skip the system information reading opportunity of the satellite information.
[0012] As another example, the UE may be configured to determine that a system information reading opportunity of satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of a layer 1 (L1) measurement opportunity or a layer 3 (L3) measurement opportunity. The UE may be configured to prioritize the system information reading opportunity of satellite information over the measurement opportunity. The UE may be configured to skip the measurement opportunity.
[0013] As an additional example, the UE may be configured to determine that a system information reading opportunity of satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of an L1 measurement opportunity or an L3 measurement opportunity. The UE may be configured to prioritize the measurement opportunity over a system information reading opportunity of satellite information. The UE may be configured to skip a system information reading opportunity of satellite information.
[0014] As another example, the UE may be configured to determine that a system information reading opportunity of satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of an L1 measurement opportunity or an L3 measurement opportunity. The UE may be configured to prioritize the system information reading opportunity of satellite information over the measurement opportunity based on determining that the measurement opportunity is an L3 measurement opportunity. The UE may be configured to skip the measurement opportunity.
[0015] In an additional example, the UE may be configured to determine that a system information reading opportunity for satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of an L1 measurement opportunity or an L3 measurement opportunity. The UE may be configured to prioritize the measurement opportunity over the system information reading opportunity for satellite information based on determining that the measurement opportunity is an aperiodic measurement opportunity. The UE may be configured to skip the system information reading opportunity for satellite information.

[0064] the term
[0065] The following is a glossary of terms used in this disclosure:
[0066] Memory medium—any of various types of non-transitory memory devices or storage devices. The term "memory medium" is intended to include installation media, such as CD-ROM, floppy disk, or tape devices; computer system memory or random access memory, such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory, such as flash memory, magnetic media, such as hard disk drives or optical storage devices; registers or other similar types of memory elements, etc. The memory medium may also include other types of non-transitory memory or combinations thereof. In addition, the memory medium may be located in a first computer system executing a program, or may be located in a different second computer system connected to the first computer system via a network such as the Internet. In the latter case, the second computer system may provide program instructions to the first computer for execution. The term "memory medium" may include two or more memory media, which may reside in different locations in different computer systems connected, for example, via a network. The memory medium may store program instructions (e.g., embodied as a computer program) that may be executed by one or more processors.
[0067] Carrier Media—Memory media as described above, as well as physical transmission media such as a bus, network, and / or other physical transmission media that convey signals such as electrical, electromagnetic, or digital signals.
[0068] Programmable hardware element - includes various hardware devices that include multiple programmable function blocks connected via programmable interconnects. Examples include FPGA (field programmable gate array), PLD (programmable logic device), FPOA (field programmable object array), and CPLD (complex PLD). Programmable function blocks can range from fine-grained (combinatorial logic or lookup table) to coarse-grained (arithmetic logic unit or processor core). Programmable hardware elements may also be referred to as "configurable logic units".
[0069] Computer system (or computer)—any of various types of computing or processing systems, including a personal computer system (PC), a mainframe computer system, a workstation, a network appliance, an Internet appliance, a personal digital assistant (PDA), a television system, a grid computing system, or other devices or combinations of devices. In general, the term "computer system" can be broadly defined to encompass any device (or combination of devices) having at least one processor that executes instructions from a memory medium.
[0070] User Equipment (UE) (or "UE device") - any of various types of computer system devices that are mobile or portable and perform wireless communications. Examples of UE devices include mobile phones or smart phones (e.g., iPhone TM, based on Android TM phones), portable gaming devices (e.g., Nintendo DS TM , PlayStation Portable TM 、Gameboy Advance TM , iPhone TM ), laptops, wearable devices (e.g., smart watches, smart glasses), PDAs, portable Internet devices, music players, data storage devices, other handheld devices, unmanned aerial vehicles (UAVs) (e.g., drones), UAV controllers (UACs), etc. In general, the term "UE" or "UE device" can be broadly defined to cover any electronic device, computing device, and / or telecommunication device (or combination of devices) that is easily transportable by a user and capable of wireless communication.
[0071] Base Station—The term “base station” has the full breadth of its ordinary meaning and includes at least a wireless communication station that is installed at a fixed location and used to communicate as part of a wireless telephone system or radio system.
[0072] Processing element (or processor) - refers to various elements or combinations of elements that are capable of performing functions in a device, such as user equipment or a cellular network device. Processing elements may include, for example, processors and associated memory, portions or circuits of individual processor cores, entire processor cores, processor arrays, circuits such as ASICs (application specific integrated circuits), programmable hardware elements such as field programmable gate arrays (FPGAs), and any of the above combinations.
[0073] Channel - a medium used to convey information from a transmitter (sender) to a receiver. It should be noted that since the characteristics of the term "channel" may vary according to different wireless protocols, the term "channel" as used herein may be considered to be used in a manner that conforms to the standards of the type of device to which the term is used. In some standards, the channel width may be variable (e.g., depending on device capabilities, frequency band conditions, etc.). For example, LTE may support scalable channel bandwidths of 1.4MHz to 20MHz. In contrast, a WLAN channel may be 22MHz wide, while a Bluetooth channel may be 1Mhz wide. Other protocols and standards may include different definitions of channels. In addition, some standards may define and use multiple types of channels, such as different channels for uplink or downlink and / or different channels for different purposes such as data, control information, etc.
[0074] Frequency band—The term “frequency band” has the full breadth of its ordinary meaning and includes at least a segment of the spectrum (eg, radio frequency spectrum) in which channels are used or set aside for the same purpose.
[0075] Wi-Fi—The term "Wi-Fi" (or WiFi) has the full scope of its usual meaning and includes at least wireless communication networks or RATs that are served by wireless LAN (WLAN) access points and provide connectivity to the Internet through these access points. Most modern Wi-Fi networks (or WLAN networks) are based on the IEEE 802.11 standard and are marketed under the name "Wi-Fi". Wi-Fi (WLAN) networks are distinct from cellular networks.
[0076] 3GPP access—refers to access (e.g., radio access technology) specified by the 3GPP standards. These accesses include, but are not limited to, GSM / GPRS, LTE, LTE-A, and / or 5G NR. In general, 3GPP access refers to various types of cellular access technologies.
[0077] Non-3GPP access - refers to any access (e.g., radio access technology) not specified by the 3GPP standards. These accesses include, but are not limited to, WiMAX, CDMA2000, Wi-Fi, WLAN, and / or fixed networks. Non-3GPP accesses can be divided into two categories, "trusted" and "untrusted": trusted non-3GPP accesses can interact directly with the Evolved Packet Core (EPC) and / or 5G Core (5GC), while untrusted non-3GPP interoperates with the EPC / 5GC via network entities (such as Evolved Packet Data Gateways and / or 5GNR Gateways). In general, non-3GPP access refers to various types of non-cellular access technologies.
[0078] Automatic—refers to an action or operation being performed by a computer system (e.g., software executed by a computer system) or a device (e.g., a circuit, a programmable hardware element, an ASIC, etc.) without the action or operation being directly specified or performed by a user input. Thus, the term "automatically" is in contrast to an operation being manually performed or specified by a user, where the user provides input to directly perform the operation. An automatic process may be initiated by input provided by a user, but subsequent actions performed "automatically" are not specified by the user, i.e., are not performed "manually," where the user specifies each action to be performed. For example, a user filling out an electronic form by selecting each field and providing input specifying information (e.g., by typing in information, selecting checkboxes, radio selections, etc.) is manually filling out the form, even though the computer system must update the form in response to the user action. The form may be automatically filled out by a computer system, where the computer system (e.g., software executed on the computer system) analyzes the fields of the form and fills out the form without any user input specifying the answers to the fields. As indicated above, a user may invoke automatic filling out of a form, but not participate in the actual filling out of the form (e.g., the user does not manually specify the answers to the fields but rather they are automatically completed). This specification provides various examples of operations that are automatically performed in response to actions that a user has taken.
[0079] Approximately - refers to a value that is close to a correct or exact value. For example, approximately can refer to a value that is within 1% to 10% of an exact (or desired) value. However, it should be noted that the actual threshold value (or tolerance) may be application dependent. For example, in some embodiments, "approximately" may mean within 0.1% of some specified or desired value, while in various other embodiments, the threshold value may be, for example, 2%, 3%, 5%, etc., depending on the desires or requirements of a particular application.
[0080] Concurrency - refers to parallel execution or implementation, where tasks, processes, or programs are executed in an at least partially overlapping manner. For example, concurrency can be achieved using "strong" or strict parallelism, where tasks are executed (at least partially) in parallel on respective computing elements, or using "weak parallelism", where tasks are executed in an interleaved manner (e.g., by time multiplexing of execution threads).
[0081] Various components may be described as being "configured to" perform one or more tasks. In such contexts, "configured to" is a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, a component may be configured to perform a task even when the component is not currently performing the task (e.g., a set of electrical conductors may be configured to electrically connect a module to another module even when the two modules are not connected). In some contexts, "configured to" may be a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, a component may be configured to perform a task even when the component is not currently turned on. Typically, circuits that form a structure corresponding to "configured to" may include hardware circuits.
[0082] For ease of description, various components may be described as performing one or more tasks. Such descriptions should be interpreted as including the phrase "configured to". The statement that a component is configured to perform one or more tasks is expressly intended not to invoke 35 U.S.C. §112(f) interpretation of that component.
[0083] Figure 1A and Figure 1B :Communication System
[0084] Figure 1A A simplified example wireless communication system according to some embodiments is shown. Note that Figure 1A The system is merely one example of a possible system, and features of the present disclosure may be implemented in any of a variety of systems, as desired.
[0085] As shown, the example wireless communication system includes a base station 102A, which communicates with one or more user equipment 106A, user equipment 106B, etc. to user equipment 106N through a transmission medium. Each user equipment in the user equipment may be referred to as a "user equipment" (UE) in this document. Therefore, user equipment 106 is referred to as a UE or UE device.
[0086] The base station (BS) 102A may be a base transceiver station (BTS) or a cell site ("cellular base station") and may include hardware that enables wireless communications with the UEs 106A-106N.
[0087] The communication area (or coverage area) of a base station may be referred to as a "cell". The base station 102A and the UE 106 may be configured to communicate over a transmission medium using any of a variety of radio access technologies (RATs), which are also referred to as wireless communication technologies or telecommunication standards, such as GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, Advanced LTE (LTE-A), 5G New Radio (5G NR), HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc. It should be noted that if the base station 102A is implemented in the context of LTE, it may alternatively be referred to as an "eNodeB" or "eNB". It should be noted that if the base station 102A is implemented in the context of 5G NR, it may alternatively be referred to as a "gNodeB" or "gNB".
[0088] As shown, the base station 102A may also be configured to communicate with a network 100 (e.g., a core network of a cellular service provider, a telecommunications network such as a public switched telephone network (PSTN), and / or the Internet, among other possibilities). Thus, the base station 102A may facilitate communications between user devices and / or between user devices and the network 100. Specifically, the cellular base station 102A may provide the UE 106 with various communication capabilities, such as voice, SMS, and / or data services.
[0089] Base station 102A and other similar base stations (such as base stations 102B, ..., 102N) operating according to the same or different cellular communication standards can therefore be provided as a network of cells that can provide continuous or nearly continuous overlapping service to UE 106A-106N and similar devices over a geographic area via one or more cellular communication standards.
[0090] Thus, while base station 102A may act as a "serving cell" for UEs 106A-N as shown in FIG. 1 , each UE 106 may also be able to receive signals from (and possibly be within communication range of) one or more other cells (which may be provided by base stations 102B-102N and / or any other base station), which may be referred to as "neighboring cells." Such cells may also be able to facilitate communications between user devices and / or between user devices and network 100. Such cells may include "macro" cells, "micro" cells, "pico" cells, and / or cells of any various other granularity that provide service area sizes. For example, base stations 102A-102B shown in FIG. 1 may be macro cells, while base station 102N may be a micro cell. Other configurations are also possible.
[0091] In some embodiments, base station 102A may be a next generation base station, e.g., a 5G New Radio (5G NR) base station or "gNB". In some embodiments, a gNB may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) network. In addition, a gNB cell may include one or more transition and reception points (TRPs). In addition, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs.
[0092] Note that the UE 106 is capable of communicating using multiple wireless communication standards. For example, the UE 106 may be configured to communicate using wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.) in addition to at least one cellular communication protocol (e.g., GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, LTE-A, 5G NR, HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc.). If desired, the UE 106 may also or alternatively be configured to communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.
[0093] Figure 1B A user equipment 106 (e.g., one of device 106A through device 106N) is shown in communication with a base station 102 and an access point 112 according to some embodiments. The UE 106 may be a device with cellular communication capabilities and non-cellular communication capabilities (e.g., Bluetooth, Wi-Fi, etc.), such as a mobile phone, a handheld device, a computer or tablet computer, or virtually any type of wireless device.
[0094] UE 106 may include a processor configured to execute program instructions stored in a memory. UE 106 may perform any of the method implementations described herein by executing such stored instructions. Alternatively or in addition, UE 106 may include a programmable hardware element, such as a field programmable gate array (FPGA) configured to perform any of the method implementations described herein or any portion of any of the method implementations described herein.
[0095] UE 106 may include one or more antennas for communicating using one or more wireless communication protocols or technologies. In some embodiments, UE 106 may be configured to communicate using, for example, CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD), LTE / Advanced LTE, or 5G NR using a single shared radio component and / or GSM, LTE, Advanced LTE, or 5G NR using a single shared radio component. The shared radio component may be coupled to a single antenna, or may be coupled to multiple antennas (e.g., for MIMO) for performing wireless communications. Typically, the radio component may include any combination of a baseband processor, an analog RF signal processing circuit (e.g., including filters, mixers, oscillators, amplifiers, etc.) or a digital processing circuit (e.g., for digital modulation and other digital processing). Similarly, the radio component may use the aforementioned hardware to implement one or more receive chains and transmit chains. For example, UE 106 may share one or more parts of a receive chain and / or a transmit chain between multiple wireless communication technologies such as those discussed above.
[0096] In some embodiments, UE 106 may include a separate transmit chain and / or receive chain (e.g., including separate antennas and other radio components) for each wireless communication protocol configured to communicate with it. As another possibility, UE 106 may include one or more radio components shared between multiple wireless communication protocols, and one or more radio components used uniquely by a single wireless communication protocol. For example, UE 106 may include a shared radio component for communicating using either LTE or 5GNR (or LTE or 1xRTT, or LTE or GSM), and a separate radio component for communicating using each of Wi-Fi and Bluetooth. Other configurations are also possible.
[0097] Figure 2 :Block diagram of base station
[0098] Figure 2 An example block diagram of a base station 102 according to some embodiments is shown. Note that Figure 3 The base station of is only one example of a possible base station. As shown, the base station 102 may include a processor 204 that may execute program instructions for the base station 102. The processor 204 may also be coupled to a memory management unit (MMU) 240 or other circuit or device, which may be configured to receive addresses from the processor 204 and convert those addresses to locations in memory (e.g., memory 260 and read-only memory (ROM) 250).
[0099] The base station 102 may include at least one network port 270. The network port 270 may be configured to couple to a telephone network and provide access to multiple devices (such as the UE device 106) as described above in FIG. Figure 2 Access to the telephone network described in.
[0100] The network port 270 (or an additional network port) may also or alternatively be configured to couple to a cellular network, such as a core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices, such as the UE device 106. In some cases, the network port 270 may be coupled to a telephone network via the core network, and / or the core network may provide a telephone network (e.g., in other UE devices served by a cellular service provider).
[0101] In some embodiments, base station 102 may be a next generation base station, such as a 5G New Radio (5G NR) base station, or "gNB".

For example, as one possibility, the base station 102 may include an LTE radio component for performing communications according to LTE and a 5GNR radio component for performing communications according to 5G NR. In this case, the base station 102 may be able to operate as both an LTE base station and a 5GNR base station.

[0113] Figure 4 :UE block diagram
[0114] Figure 4 An example simplified block diagram of a communication device 106 according to some embodiments is shown. Note that Figure 4 The block diagram of the communication device is only an example of a possible communication device. According to the embodiment, the communication device 106 can be a user equipment (UE) device, a mobile device or a mobile station, a wireless device or a wireless station, a desktop computer or a computing device, a mobile computing device (e.g., a laptop computer, a notebook or a portable computing device), a tablet computer, an unmanned aerial vehicle (UAV), a UAV controller (UAC) and / or a combination of devices and other devices. As shown in the figure, the communication device 106 may include a group of components 400 configured to perform core functions. For example, the group of components may be implemented as a system on a chip (SOC), which may include parts for various purposes. Alternatively, the group of components 400 may be implemented as a separate component or a group of components for various purposes. This group of components 400 may be (e.g., communicatively; directly or indirectly) coupled to various other circuits of the communication device 106.
[0115] For example, the communication device 106 may include various types of memory (e.g., including NAND flash memory 410), input / output interfaces such as connector I / F 420 (e.g., for connecting to a computer system; a docking station; a charging station; input devices such as a microphone, a camera, a keyboard; output devices such as a speaker; etc.), a display 460 that may be integrated with the communication device 106 or external to the communication device, and cellular communication circuits 430 such as for 5G NR, LTE, GSM, etc., and short-range to medium-range wireless communication circuits 429 (e.g., Bluetooth TM In some embodiments, the communication device 106 may include wired communication circuitry (not shown), such as, for example, a network interface card for Ethernet.
[0116] Cellular communication circuitry 430 may be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 435 and 436 as shown. Short-range to medium-range wireless communication circuitry 429 may also be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 437 and 438 as shown. Alternatively, short-range to medium-range wireless communication circuitry 429 may be (e.g., communicatively; directly or indirectly) coupled to antennas 435 and 436 in addition to or in lieu of being (e.g., communicatively; directly or indirectly) coupled to antennas 437 and 438. Short-range to medium-range wireless communication circuitry 429 and / or cellular communication circuitry 430 may include multiple receive chains and / or multiple transmit chains for receiving and / or transmitting multiple spatial streams, such as in a multiple-input multiple-output (MIMO) configuration.
[0117] In some embodiments, as further described below, the cellular communication circuit 430 can include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G NR). In addition, in some embodiments, the cellular communication circuit 430 can include a single transmit chain that can switch between radio components dedicated to specific RATs. For example, a first radio component can be dedicated to a first RAT, such as LTE, and can communicate with a dedicated receive chain and a transmit chain shared with an additional radio component, such as a second radio component that can be dedicated to a second RAT (e.g., 5G NR) and can communicate with the dedicated receive chain and the shared transmit chain.
[0118] Communication device 106 may also include one or more user interface elements and / or be configured for use with one or more user interface elements. User interface elements may include any of various elements, such as display 460 (which may be a touch screen display), keyboard (which may be a discrete keyboard or may be implemented as a part of a touch screen display), mouse, microphone and / or loudspeaker, one or more cameras, one or more buttons, and / or any of various other elements capable of providing information to a user and / or receiving or interpreting user input.
[0119] The communication device 106 may also include one or more smart cards 445 with SIM (Subscriber Identity Module) functionality, such as one or more UICC (Universal Integrated Circuit Card) cards 445. Note that the term "SIM" or "SIM entity" is intended to include any of various types of SIM implementations or SIM functions, such as one or more UICC cards 445, one or more eUICCs, one or more eSIMs, removable or embedded, etc. In some embodiments, the UE 106 may include at least two SIMs. Each SIM may execute one or more SIM applications and / or implement SIM functions in other ways. Thus, each SIM may be a single smart card that may be embedded, for example, soldered to a circuit board in the UE 106, or each SIM 410 may be implemented as a removable smart card. Thus, the SIM may be one or more removable smart cards (such as a UICC card, sometimes referred to as a "SIM card"), and / or the SIM 410 may be one or more embedded cards (such as an embedded UICC (eUICC), sometimes referred to as an "eSIM" or "eSIM card"). In some embodiments (such as when the SIM includes an eUICC), one or more of the SIMs may implement embedded SIM (eSIM) functionality; in such embodiments, a single SIM of the SIM may execute multiple SIM applications. Each SIM may include components such as a processor and / or a memory; instructions for performing SIM / eSIM functionality may be stored in the memory and executed by the processor. In some embodiments, the UE 106 may include a combination of removable smart cards and fixed / non-removable smart cards (such as one or more eUICC cards that implement eSIM functionality) as needed. For example, the UE 106 may include two embedded SIMs, two removable SIMs, or a combination of one embedded SIM and one removable SIM. Various other SIM configurations are also contemplated.
[0120] As described above, in some embodiments, UE 106 may include two or more SIMs. Including two or more SIMs in UE 106 may allow UE 106 to support two different phone numbers, and may allow UE 106 to communicate on corresponding two or more corresponding networks. For example, the first SIM may support a first RAT such as LTE, and the second SIM 410 may support a second RAT such as 5G NR. Of course, other specific implementations and RATs are also possible. In some embodiments, when UE 106 includes two SIMs, UE 106 may support dual card dual communication (DSDA) functionality. The DSDA functionality may allow UE 106 to be connected to two networks (and use two different RATs) at the same time, or allow two connections supported by two different SIMs using the same or different RATs to be maintained on the same or different networks at the same time. The DSDA functionality may also allow UE 106 to receive voice calls or data traffic on any phone number at the same time. In some embodiments, voice calls may be packet-switched communications. In other words, voice calls may be received using voice over LTE (VoLTE) technology and / or voice over NR (VoNR) technology. In some embodiments, the UE 106 may support dual SIM dual standby (DSDS) functionality. The DSDS functionality may allow either of the two SIMs in the UE 106 to standby for a voice call and / or data connection. In DSDS, when a call / data is established on one SIM, the other SIM is no longer active. In some embodiments, the DSDx functionality (DSDA or DSDS functionality) may be implemented using a single SIM (e.g., eUICC) that executes multiple SIM applications for different carriers and / or RATs.
[0121] As shown, SOC 400 may include a processor 402 that may execute program instructions for communication device 106 and a display circuit 404 that may perform graphics processing and provide display signals to display 460. Processor 402 may also be coupled to a memory management unit (MMU) 440 (which may be configured to receive addresses from processor 402 and translate those addresses into locations in memory (e.g., memory 406, read-only memory (ROM) 450, NAND flash memory 410), and / or to other circuits or devices (such as display circuit 404, short-range to medium-range wireless communication circuit 429, cellular communication circuit 430, connector I / F 420, and / or display 460). MMU 440 may be configured to perform memory protection and page table translation or setup. In some embodiments, MMU 440 may be included as part of processor 402.
[0122] As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuits. The communication device 106 may be configured to perform a method for enhancing system information reading in an NTN, including systems, methods, and mechanisms for determining timing and / or opportunity for UE to read system information and determining scheduling restrictions when system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above, as further described herein.
[0123] As described herein, the communication device 106 may include hardware components and software components for implementing the above-described features of the communication device 106 to communicate a scheduling profile for power saving to the network. The processor 402 of the communication device 106 may be configured to implement some or all of the features described herein, for example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). Alternatively (or in addition), the processor 402 may be configured as a programmable hardware element, such as an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more other components in other components 400, 404, 406, 410, 420, 429, 430, 440, 445, 450, 460, the processor 402 of the communication device 106 may be configured to implement some or all of the features described herein.
[0124] In addition, as described herein, processor 402 may include one or more processing elements. Thus, processor 402 may include one or more integrated circuits (ICs) configured to perform the functions of processor 402. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 402.
[0125] In addition, as described herein, the cellular communication circuit 430 and the short-range to medium-range wireless communication circuit 429 may each include one or more processing elements. In other words, one or more processing elements may be included in the cellular communication circuit 430, and similarly, one or more processing elements may be included in the short-range to medium-range wireless communication circuit 429. Therefore, the cellular communication circuit 430 may include one or more integrated circuits (ICs) configured to perform the functions of the cellular communication circuit 430. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the cellular communication circuit 430. Similarly, the short-range to medium-range wireless communication circuit 429 may include one or more ICs configured to perform the functions of the short-range to medium-range wireless communication circuit 429. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the short-range to medium-range wireless communication circuit 429.
[0126] Figure 5 : Block diagram of a cellular communication circuit
[0127] Figure 5 An example simplified block diagram of a cellular communication circuit according to some embodiments is shown. Note that Figure 5 The block diagram of the cellular communication circuit of is only one example of possible cellular communication circuits. According to an embodiment, the cellular communication circuit 530 (which may be the cellular communication circuit 430) may be included in a communication device such as the communication device 106 described above. As described above, the communication device 106 may be a user equipment (UE) device, a mobile device or mobile station, a wireless device or wireless station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet computer, and / or a combination of devices, among other devices.
[0128] Cellular communication circuitry 530 may be (eg, communicatively; directly or indirectly) coupled to one or more antennas, such as ( Figure 4 In some embodiments, the cellular communication circuit 530 may include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G NR). For example, Figure 5 As shown, cellular communication circuitry 530 may include modem 510 and modem 520. Modem 510 may be configured for communication according to a first RAT (e.g., such as LTE or LTE-A), and modem 520 may be configured for communication according to a second RAT (e.g., such as 5G NR).
[0129] As shown, the modem 510 may include one or more processors 512 and a memory 516 in communication with the processor 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuits for sending and receiving radio signals. For example, the RF front end 530 may include a receiving circuit (RX) 532 and a transmitting circuit (TX) 534. In some embodiments, the receiving circuit 532 may communicate with a downlink (DL) front end 550, which may include circuits for receiving radio signals via an antenna 335a.
[0130] Similarly, the modem 520 may include one or more processors 522 and a memory 526 in communication with the processor 522. The modem 520 may communicate with the RF front end 540. The RF front end 540 may include circuits for sending and receiving radio signals. For example, the RF front end 540 may include a receiving circuit 542 and a transmitting circuit 544. In some embodiments, the receiving circuit 542 may communicate with the DL front end 560, which may include circuits for receiving radio signals via the antenna 335b.
[0131] In some embodiments, the switch 570 may couple the transmit circuit 534 to an uplink (UL) front end 572. In addition, the switch 570 may couple the transmit circuit 544 to the UL front end 572. The UL front end 572 may include circuitry for transmitting radio signals via the antenna 336. Thus, when the cellular communication circuit 530 receives an instruction to transmit according to a first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572) supported by the modem 510, the switch 570 may be switched to a first state that allows the modem 510 to transmit signals according to the first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572). Similarly, when the cellular communication circuit 530 receives an instruction to transmit according to a second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572) supported by the modem 520, the switch 570 may be switched to a second state that allows the modem 520 to transmit signals according to the second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572).
[0132] In some embodiments, the cellular communication circuit 530 may be configured to perform methods for enhancing system information reading in an NTN, including systems, methods, and mechanisms for determining the timing and / or opportunity for a UE to read system information and determining scheduling restrictions when the system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above, as further described herein.
[0133] As described herein, the modem 510 may include hardware components and software components for implementing the above-described features or for time-division multiplexing UL data of NSANR operations and various other technologies described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 512 may be configured to implement some or all of the features described herein. Alternatively (or in addition), the processor 512 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 530, 532, 534, 550, 570, 572, 335, and 336, the processor 512 may be configured to implement some or all of the feature parts described herein.
[0134] In addition, as described herein, processor 512 may include one or more processing elements. Thus, processor 512 may include one or more integrated circuits (ICs) configured to perform the functions of processor 512. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 512.
[0135] As described herein, the modem 520 may include hardware components and software components for implementing the above features for enhancing system information reading in NTN, including systems, methods and mechanisms for determining the timing and / or opportunity for UE to read system information and determining scheduling restrictions when system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, such as in 5G NR systems and above and various other technologies described herein. The processor 522 may be configured to implement some or all of the features described herein, for example by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). Alternatively (or in addition), the processor 522 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 540 , 542 , 544 , 550 , 570 , 572 , 335 , and 336 , processor 522 may be configured to implement some or all of the features described herein.
[0136] In addition, as described herein, processor 522 may include one or more processing elements. Thus, processor 522 may include one or more integrated circuits (ICs) configured to perform the functions of processor 522. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 522.
[0137] Fig. 6A , Figure 6B and Figure 7 : 5G core network architecture—interworking with Wi-Fi
[0138] In some embodiments, the 5G core network (CN) can be accessed via (or through) a cellular connection / interface (e.g., via a 3GPP communication architecture / protocol) and a non-cellular connection / interface (e.g., a non-3GPP access architecture / protocol such as a Wi-Fi connection). Fig. 6AAn example of a 5G network architecture according to some embodiments is shown, which combines both 3GPP (e.g., cellular) access and non-3GPP (e.g., non-cellular) access to 5G CN. As shown, a user equipment device (e.g., such as UE106) can access 5G CN through both a radio access network (RAN, such as gNB 604, which can be a base station 102) and an access point (such as AP612). AP 612 may include a connection to the Internet 600 and a connection to a non-3GPP interworking function (N3IWF) 603 network entity. N3IWF may include a connection to a core access and mobility management function (AMF) 605 of the 5G CN. AMF 605 may include an instance of a 5G mobility management (5G MM) function associated with UE 106. In addition, the RAN (e.g., gNB 604) may also have a connection to AMF 605. Therefore, the 5G CN can support unified authentication on both connections and allow simultaneous registration of UE 106 access via both gNB 604 and AP 612. As shown in the figure, AMF 605 may include one or more functional entities associated with 5GCN (e.g., network slice selection function (NSSF) 620, short message service function (SMSF) 622, application function (AF) 624, unified data management (UDM) 626, policy control function (PCF) 628 and / or authentication server function (AUSF) 630). It should be noted that these functional entities can also be supported by the session management function (SMF) 606a and SMF 606b of 5G CN. AMF 605 can be connected to (or communicate with) SMF 606a. In addition, gNB 604 can communicate with (or be connected to) user plane function (UPF) 608a, which can also communicate with SMF 606a. Similarly, N3IWF 603 can communicate with UPF 608b, which can also communicate with SMF 606b. Both UPFs can communicate with data networks (e.g., DN 610a and 610b) and / or the Internet 600 and Internet Protocol (IP) Multimedia Subsystem / IP Multimedia Core Network Subsystem (IMS) Core Network 610.
[0139] Figure 6BAn example of a 5G network architecture according to some embodiments is shown, which combines both dual 3GPP (e.g., LTE and 5G NR) access to 5GCN and non-3GPP access. As shown, a user equipment device (e.g., such as UE106) can access 5G CN through both a radio access network (RAN, such as gNB 604 or eNB 602, which can be a base station 102) and an access point (such as AP 612). AP 612 may include a connection to the Internet 600 and a connection to the N3IWF 603 network entity. N3IWF may include a connection to AMF 605 of 5G CN. AMF 605 may include an instance of a 5G MM function associated with UE 106. In addition, RAN (e.g., gNB 604) may also have a connection to AMF 605. Therefore, 5G CN can support unified authentication on two connections and allow simultaneous registration of UE 106 access via both gNB 604 and AP 612. In addition, the 5G CN may support dual registration of UEs on both the legacy network (e.g., LTE via eNB 602) and the 5G network (e.g., via gNB 604). As shown, the eNB 602 may have connections to a mobility management entity (MME) 642 and a serving gateway (SGW) 644. The MME 642 may have connections to both the SGW 644 and the AMF 605. In addition, the SGW 644 may have connections to both the SMF 606a and the UPF 608a. As shown, the AMF 605 may include one or more functional entities associated with the 5G CN (e.g., NSSF 620, SMSF 622, AF 624, UDM 626, PCF 628, and / or AUSF 630). It should be noted that the UDM 626 may also include a home subscriber server (HSS) function, and the PCF may also include a policy and charging rules function (PCRF). It should also be noted that these functional entities can also be supported by SMF 606a and SMF 606b of 5G CN. AMF 606 can be connected to (or communicate with) SMF 606a. In addition, gNB 604 can communicate with (or be connected to) UPF 608a, which can also communicate with SMF 606a. Similarly, N3IWF 603 can communicate with UPF 608b, which can also communicate with SMF 606b. Both UPFs can communicate with data networks (e.g., DN 610a and 610b) and / or the Internet 600 and the IMS core network 610.
[0140] It should be noted that in various embodiments, one or more of the above-mentioned network entities may be configured to perform methods for enhancing system information reading in NTN, including systems, methods and mechanisms for determining the timing and / or opportunity for UE to read system information and determining scheduling restrictions when the system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above, for example as further described herein.
[0141] Figure 7 An example of a baseband processor architecture for a UE (eg, such as UE 106) is shown in accordance with some embodiments. Figure 7 The baseband processor architecture 700 described in the figure may be implemented on one or more radio components (e.g., the radio components 429 and / or 430 described above) or modems (e.g., modems 510 and / or 520) as described above. As shown, the non-access layer (NAS) 710 may include a 5G NAS 720 and a traditional NAS 750. The traditional NAS 750 may include a communication connection with a traditional access layer (AS) 770. The 5G NAS 720 may include a communication connection with a 5G AS 740 and a non-3GPP AS 730 and a Wi-Fi AS 732. The 5G NAS 720 may include functional entities associated with two access layers. Therefore, the 5G NAS 720 may include multiple 5G MM entities 726 and 728 and 5G session management (SM) entities 722 and 724. The traditional NAS 750 may include functional entities such as a short message service (SMS) entity 752, an evolved packet system (EPS) session management (ESM) entity 754, a session management (SM) entity 756, an EPS mobility management (EMM) entity 758, and a mobility management (MM) / GPRS mobility management (GMM) entity 760. In addition, the traditional AS 770 may include functional entities such as an LTE AS 772, a UMTS AS 774, and / or a GSM / GPRS AS 776.
[0142] Thus, the baseband processor architecture 700 allows for a common 5G-NAS for both 5G cellular and non-cellular (e.g., non-3GPP access). Note that, as shown, 5G MM can maintain separate connection management and registration management state machines for each connection. In addition, a device (e.g., UE 106) can register to a single PLMN (e.g., 5G CN) using 5G cellular access as well as non-cellular access. In addition, a device can be in a connected state in one access and in an idle state in another access, or vice versa. Finally, there may be common 5G-MM processes (e.g., registration, deregistration, identification, authentication, etc.) for both accesses.
[0143] It should be noted that in various embodiments, one or more of the above-mentioned functional entities of the 5G NAS and / or 5G AS may be configured to perform methods for enhancing system information reading in the NTN, including systems, methods and mechanisms for determining the timing and / or opportunity for the UE to read system information and determining scheduling restrictions when the system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements, for example in 5G NR systems and above, for example as further described herein.
[0144] Enhanced system information reading mechanism
[0145] In the 3GPP standard development, various agreements have been reached for the reading of system information (SI) for non-terrestrial networks (NTNs). For example, if the timing information of valid neighbor cells and / or target cells in terms of validity or accuracy is not provided to the UE, it has been agreed that the availability of valid target satellite information is defined as an auxiliary condition. In addition, it has been agreed that the required parameters for measurement include ephemeris (e.g., position over time and / or velocity over time), epoch time (e.g., the number of seconds that have elapsed since 12:00 noon Greenwich Mean Time (GMT) on January 1, 1970, excluding leap seconds), SMTC (measurement timing configuration based on SSB (synchronization signal block)), downlink polarization information, serving cell stop time and reference position for idle mode measurement trigger in non-geostationary orbit (NGSO) fixed cells (if applicable), feeder link delay of neighbor cells for neighbor cell SMTC adjustment (e.g., common timing advance and K_MAC (e.g., downlink timing of the network (e.g., base station) side) and uplink frame timing), and a separate validity timer. In addition, it has been agreed that the parameters required for mobility include target cell ephemeris information, epoch time of the ephemeris, common timing advance, validity timer information for target cell mobility, downlink and uplink polarization information, K_offset and K_MAC (e.g., to determine UE-base station round trip time and perform RACH to the target cell). In addition, if the auxiliary conditions are not met, the requirements may not apply, for example, the additional delay will not be explicitly defined. It is noted that if the auxiliary conditions are not met before obtaining new ephemeris information, the UE is allowed to not perform radio resource management (RRM) measurements (and reporting).
[0146] Furthermore, with respect to measurement requirements and serving cell system information block (SIB) reading time, it has been agreed that if the necessary information for NTN neighbor cell measurements is not provided, the requirements do not apply. However, the UE needs to read the system information of the satellite information before measurements or mobility behavior. However, it has not been defined (e.g., agreed) when the UE should perform a system information reading of the satellite information for the serving cell or what the UE behavior should be during the system information reading, such as when the system information reading conflicts with data reception and / or such as when the system information reading conflicts with uplink transmission.
[0147] The embodiments described herein provide systems, methods, and mechanisms for enhancing system information reading in NTNs, including systems, methods, and mechanisms for determining the timing and / or opportunity for UEs to read system information and determining scheduling restrictions when system information reading conflicts with other UE behaviors, such as receiving data channels and / or control channels from a serving cell, uplink transmissions, and / or radio resource management (RRM) measurements.
[0148] For example, in some embodiments, the network (e.g., a base station) may update system information (e.g., ephemeris information) of satellite information in a periodic manner, such as every X milliseconds (ms). Note that the system information may include a master information block (MIB), a system information block (SIB) 1 (SIB1), and / or a SIB for ephemeris and other satellite information. The UE may read the system information of its serving cell or target cell. The system information may include ephemeris information and other satellite information for neighboring cells and / or target cells. In some cases, the UE may read (e.g., receive) the system information periodically, based on an event, based on a mobility condition, based on a network trigger, and / or based on UE behavior.
[0149] For example, in some cases, the UE may read system information every X milliseconds to every k*X milliseconds, where k is a scaling factor based on the network system information update rate (e.g., periodicity). In some examples, X may be predefined, for example, by the 3GPP standard, and / or may be network specified or configured. In some examples, k may be predefined, for example, by the 3GPP standard, and / or may be network specified or configured.
[0150] As another example, in some cases, the UE may read (e.g., receive) system information based at least in part on a triggering event (e.g., the system information reading may be event-based). For example, when the network configures a measurement object to the UE, the UE may be triggered to read system information of the serving cell in preparation for the measurement object. As another example, when the network configures a handover to the UE, the UE may be triggered to read system information of the source serving cell for target cell measurements for handover purposes. As another example, after a radio link failure (RLF), before the UE starts to perform radio resource control (RRC) reestablishment, the UE may be triggered to read system information of the target cell for RRC reestablishment on the target cell.
[0151] As another example, in some cases, the UE may read the system information based on the mobility condition (such as channel condition, timing condition and / or distance condition). For example, when the serving cell signal quality or strength is lower than a threshold, the UE may be triggered to read the system information of the serving cell, for example, to prepare for the measurement for mobility. The threshold may be predefined by the 3GPP standard and / or signaled by the network, for example. As another example, when the configured timing is reached, the UE may be triggered to read the system information of the source serving cell for the target cell measurement for mobility. It should be noted that the configured timing is a timing for indicating when the UE is allowed to perform mobility, for example, the network indicates that the UE may perform handover within [T1, T2]. The UE may read the system information after T1 but before T2. As another example, when the configured distance threshold is met, the UE may be triggered to read the system information of the serving cell to prepare for the measurement for mobility. The distance threshold may be the distance between the UE and the serving cell and / or the distance between the UE and the target cell. The distance threshold may be predefined by the 3GPP standard and / or signaled by the network, for example.
[0152] As yet another example, in some cases, the UE may read the system information when triggered by a network indication. For example, the network may indicate to the UE when it updates the system information of the satellite information. Then, based on the network indication, the UE may read the system information. As another example, the network may indicate to the UE a period for reading the system information of the satellite information. As another example, the network may command the UE to read the system information of the satellite information, for example, by sending to the UE an indication for triggering the reading of the system information at the UE.
[0153] As yet another example, in some cases, the UE may read the system information before the UE performs a specific action (or function). For example, the UE may read the system information of the satellite information before the serving cell measurement or the neighboring cell measurement. As another example, the UE may read the system information of the satellite information before any RACH transmission.
[0154] In some cases, when the system information reading opportunity of satellite information conflicts with the data channel and / or control channel reception from the serving cell and the UE cannot (substantially) concurrently receive both the system information of satellite information and the data channel and / or control channel, scheduling restrictions may be applied to the data channel and / or control channel. In other words, the UE may prioritize the system information reading of satellite information and discard (skip) the data channel and / or control channel reception.
[0155] In some cases, when the system information reading opportunity of satellite information conflicts with the reception of a data channel and / or a control channel from a serving cell and the UE cannot (substantially) concurrently receive both the system information of satellite information and the data channel and / or the control channel, the scheduling restriction may be applied to the data channel but not to the control channel. In other words, the UE may prioritize the reading of system information of satellite information and discard (skip) the reception of the data channel. However, the UE may prioritize the reception of a control channel (e.g., paging) over the reading of system information of satellite information and discard (skip) the reception of system information of satellite information.
[0156] In some cases, when the system information reading opportunity of satellite information conflicts with uplink channel transmission (e.g., due to time division duplex (TDD) configuration and / or due to half-duplex frequency division duplex (FDD) configuration), scheduling restrictions may be applied to the uplink channel. In other words, the UE may prioritize the system information reading of satellite information over the uplink channel transmission and discard (skip) the uplink channel transmission.
[0157] In some cases, when the system information reading opportunity of satellite information conflicts with uplink channel transmission (e.g., due to TDD configuration and / or due to half-duplex FDD configuration), scheduling restrictions may be applied to satellite information reading. In other words, the UE may prioritize uplink channel transmission over system information reading of satellite information and discard (skip) system information reception of satellite information.
[0158] In some cases, when a system information reading opportunity of satellite information conflicts with an uplink channel transmission (e.g., due to a TDD configuration and / or due to a half-duplex FDD configuration), a scheduling restriction may be applied to the uplink channel unless the uplink channel transmission is an aperiodic uplink channel transmission (e.g., such as an aperiodic sounding reference signal (SRS) transmission) and / or a hybrid automatic repeat request (HARQ) feedback. In other words, the UE may prioritize the aperiodic uplink channel transmission and / or the HARQ feedback transmission over the system information reading of satellite information and discard (skip) the system information reception of satellite information, and may prioritize the system information reading of satellite information over all other types of uplink channel transmissions and discard (skip) such uplink channel transmissions.
[0159] In some cases, when a system information reading opportunity of satellite information conflicts with a measurement opportunity such as a mobility-based RRM measurement (e.g., SSB / CSI-RS for layer 3 (L3) measurement) and / or an RRM measurement for layer 1 (L1) (e.g., RLM / CBD / BFD / L1-RSRP measurement) and the UE is unable to (substantially) concurrently receive both the system information and the measurement opportunity, the UE may apply measurement restriction to the measurement opportunity. In other words, the UE may prioritize the reading of system information of satellite information over performing measurement, e.g., prioritizing performing L3 measurement and / or L1 measurement, and may discard (skip) the measurement opportunity.
[0160] In some cases, when a system information reading opportunity of satellite information conflicts with a measurement opportunity such as mobility-based RRM measurement (e.g., SSB / CSI-RS for layer 3 (L3) measurement) and / or RRM measurement for layer 1 (L1) (e.g., RLM / CBD / BFD / L1-RSRP measurement) and the UE cannot (substantially) concurrently receive both the system information and the measurement opportunity, the UE may prioritize the measurement opportunity over the system information reading of satellite information. In other words, the UE may perform mobility-based RRM measurement and / or RRM measurement for L1 and discard (skip) system information reception of satellite information.
[0161] In some cases, when a system information reading opportunity of satellite information conflicts with a measurement opportunity such as mobility-based RRM measurement (e.g., SSB / CSI-RS for layer 3 (L3) measurement) and / or RRM measurement for layer 1 (L1) (e.g., RLM / CBD / BFD / L1-RSRP measurement) and the UE is unable to (substantially) concurrently receive both the system information and the measurement opportunity, the UE may prioritize the RRM measurement for L1 over the system information reading of satellite information, rather than the mobility-based RRM measurement. In other words, the UE may perform RRM measurement for L1 and discard (skip) system information reception of satellite information, but prioritize the system information reading of satellite information over performing mobility-based RRM measurement (e.g., prioritizing performing L3 measurement), and may discard (skip) the mobility-based RRM measurement.
[0162] In some cases, when a system information reading opportunity for satellite information conflicts with a measurement opportunity such as mobility-based RRM measurement (e.g., SSB / CSI-RS for layer 3 (L3) measurement) and / or RRM measurement for layer 1 (L1) (e.g., RLM / CBD / BFD / L1-RSRP measurement) and the UE is not able to (substantially) concurrently receive both the system information and the measurement opportunity, the UE may prioritize specific RRM measurement for L1 (e.g., such as L1 AP measurement) over system information reading for satellite information, rather than any other type of measurement opportunity. In other words, the UE may perform specific RRM measurement for L1 (e.g., such as L1 AP measurement) and discard (skip) system information reception for satellite information, but prioritize system information reading for satellite information over all other measurement opportunities and may discard (skip) other types of measurement opportunities.
[0163] Figure 8 A block diagram of an example of a method for receiving satellite information from a non-terrestrial network (NTN) according to some embodiments is shown. Among other devices, Figure 8 The method shown in can also be used together with any one of the system, method or device shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can be operated as follows.
[0164] At 802, a UE, such as UE 106, may determine that a triggering event for system information reading of satellite information has occurred. The triggering event for system information reading of satellite information may include at least one of: network behavior, UE behavior, channel condition, timing condition, distance condition, or network indication.
[0165] In some cases, the network behavior may include the network periodically updating the system information of the satellite information. In this case, to determine that a triggering event for the system information reading of the satellite information has occurred, the UE may determine that a time period has passed since a previous reading of the system information reading of the satellite information. The time period may be based at least in part on a period of network updates of the system information reading of the satellite information. The period of network updates may be defined by a 3GPP standard. In some cases, the time period may be based at least in part on a scaling period of network updates of the system information reading of the satellite information. The scaling period may be a product of a scaling factor and a period of network updates. The scaling factor may be defined by a 3GPP standard.
[0166] In some cases, the network behavior may include configuring the measurement object to the UE. In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine to read the system information of the satellite information in preparation for the measurement object.
[0167] In some cases, the network behavior may include configuring a handover to the UE. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information in preparation for the handover. In some cases, in order to read system information of satellite information based on the occurrence of a triggering event, the UE may read system information of satellite information measured by the target cell from the source serving cell for handover purposes.
[0168] In some cases, the UE behavior may include performing a radio resource control (RRC) reestablishment after a radio link failure (RLF). In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine to read system information of satellite information for RRC reestablishment of the target cell on the target cell.
[0169] In some cases, the UE behavior may include performing serving cell measurement or neighboring cell measurement. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information before performing serving cell measurement or neighboring cell measurement.
[0170] In some embodiments, the UE behavior may include performing a random access channel (RACH) transmission. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information before performing a RACH transmission.
[0171] In some cases, the channel condition may include that the serving cell signal quality drops below a threshold. In this case, in order to determine that a triggering event for reading the system information of the satellite information has occurred, the UE may determine that the serving cell signal quality is less than the threshold. In this case, in order to read the system information of the satellite information based on the occurrence of the triggering event, the UE may read the system information of the satellite information of the serving cell in preparation for mobility measurement. The threshold may be defined by the 3GPP standard or signaled by the network.
[0172] In some cases, the channel condition may include that the serving cell signal strength drops below a threshold. In this case, in order to determine that a triggering event for reading the system information of the satellite information has occurred, the UE may determine that the serving cell signal strength is less than the threshold. In this case, in order to read the system information of the satellite information based on the occurrence of the triggering event, the UE may read the system information of the satellite information of the serving cell in preparation for mobility measurement. The threshold may be defined by the 3GPP standard or signaled by the network.
[0173] In some cases, the timing condition may include a configured mobility window during which the UE is allowed to perform a mobility procedure. In this case, to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine that the configured mobility window has started but has not ended. In this case, to read the system information of satellite information based on the occurrence of the triggering event, the UE may read the system information of satellite information of the serving cell for target cell measurement for the mobility procedure.
[0174] In some cases, the distance condition may include that the distance between the UE and the serving cell exceeds a threshold. In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine that the distance from the UE to the serving cell is greater than a threshold. The threshold may be defined by the 3GPP standard or signaled by the network.
[0175] In some cases, the distance condition may include a distance between the UE and the target cell falling below a threshold. In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine that the distance from the UE to the target cell is less than a threshold. The threshold may be defined by the 3GPP standard or signaled by the network.
[0176] In some cases, the network indication may be at least one of an explicit command or a period for reading the system information of the satellite information. In some cases, the UE may receive an explicit command each time the network updates the system information of the satellite information.
[0177] At 804, the UE may read system information of satellite information based on the occurrence of a triggering event. The system information reading of satellite information may include at least ephemeris information. In some cases, the system information reading of satellite information may (additionally) include epoch time (e.g., the number of seconds that have passed since 12:00 noon Greenwich Mean Time (GMT) on January 1, 1970, excluding leap seconds), SMTC (measurement timing configuration based on SSB (synchronization signal block)), downlink polarization information, serving cell stop time and reference position for idle mode measurement trigger in non-geostationary orbit (NGSO) fixed cells (if applicable), feeder link delay of neighboring cells for neighboring cell SMTC adjustment (e.g., common timing advance and K_MAC (e.g., an indication of the amount of misalignment between downlink and uplink frame timing on the network (e.g., base station) side), separate validity timing, and the like. timer, target cell ephemeris information, epoch time of ephemeris, common timing advance, validity timer information for target cell mobility, downlink and uplink polarization information, K_offset and K_MAC (e.g., to determine UE-base station round trip time and perform RACH to the target cell). In some cases, the system information reading of satellite information may include one or more of the following: a master information block (MIB), a system information block 1 (SIB1), or SIBx. In some cases, reading the system information of satellite information based on the occurrence of a triggering event may include the UE reading the system information of the UE's serving cell. In some cases, the system information of the UE's serving cell may include system information of satellite information of a neighboring cell or a target cell.
[0178] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with receiving a data channel or a control channel from the serving cell. The UE may prioritize the system information reading opportunity of the satellite information over receiving the data channel. The UE may discard the reception of the data channel. In some cases, the UE may prioritize the system information reading opportunity of the satellite information over receiving the control channel and discard the reception of the control channel. In some cases, the UE may prioritize the reception of the control channel over the system information reading opportunity of the satellite information and skip the system information reading opportunity of the satellite information.
[0179] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with the uplink transmission. The UE may prioritize the system information reading opportunity of the satellite information over the uplink transmission. The UE may skip the uplink transmission.
[0180] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with the uplink transmission. The UE may prioritize the uplink transmission over the system information reading opportunity of the satellite information. The UE may skip the system information reading opportunity of the satellite information.
[0181] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with the uplink transmission. The UE may prioritize the uplink transmission over the system information reading opportunity of the satellite information based on determining that the uplink transmission is a non-periodic uplink transmission. The UE may skip the system information reading opportunity of the satellite information. In some cases, the UE may prioritize the system information reading opportunity of the satellite information over the uplink transmission based on determining that the uplink transmission is a periodic or semi-persistent uplink transmission, and skip the uplink transmission.
[0182] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with the measurement opportunity. The measurement opportunity may be one of the layer 1 (L1) measurement opportunity or the layer 3 (L3) measurement opportunity. The UE may prioritize the system information reading opportunity of the satellite information over the measurement opportunity. The UE may skip the measurement opportunity.
[0183] In some cases, the UE may determine that the system information reading opportunity of the satellite information conflicts with the measurement opportunity. The measurement opportunity may be one of a layer 1 (L1) measurement opportunity or a layer 3 (L3) measurement opportunity. The UE may prioritize the measurement opportunity over the system information reading opportunity of the satellite information. The UE may skip the system information reading opportunity of the satellite information.
[0184] In some cases, the UE may determine that a system information reading opportunity for satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of a layer 1 (L1) measurement opportunity or a layer 3 (L3) measurement opportunity. The UE may prioritize a system information reading opportunity for satellite information over the measurement opportunity based on determining that the measurement opportunity is an L3 measurement opportunity. The UE may skip the measurement opportunity. In some cases, the UE may prioritize a system information reading opportunity for satellite information based on determining that the measurement opportunity is an L1 measurement opportunity, and skip the system information reading opportunity for satellite information.
[0185] In some cases, the UE may determine that a system information reading opportunity for satellite information conflicts with a measurement opportunity. The measurement opportunity may be one of a layer 1 (L1) measurement opportunity or a layer 3 (L3) measurement opportunity. The UE may prioritize the measurement opportunity over the system information reading opportunity for satellite information based on determining that the measurement opportunity is an aperiodic measurement opportunity. The UE may skip the system information reading opportunity for satellite information. In some cases, the UE may prioritize the system information reading opportunity for satellite information over the measurement opportunity based on determining that the measurement opportunity is a periodic or semi-persistent measurement opportunity and skip the measurement opportunity.

Fig. 9 The method shown can also be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can operate as follows.
[0187] At 902, a UE, such as UE 106, may determine that a system information reading opportunity of satellite information conflicts with receiving a data channel or a control channel from a serving cell.
[0188] At 904, the UE may prioritize a system information reading opportunity for satellite information over receiving a data channel.
[0189] At 906, the UE may drop reception of the data channel.
[0190] In some cases, the UE may prioritize the system information reading opportunity of satellite information over receiving the control channel and discard the reception of the control channel. In some cases, the UE may prioritize the system information reading opportunity of satellite information over receiving the control channel and skip the system information reading opportunity of satellite information.
[0191] In some cases, the UE may determine that a triggering event for reading system information for satellite information has occurred. The triggering event for reading system information for satellite information may include at least one of the following: network behavior, UE behavior, channel conditions, timing conditions, distance conditions, or network indications. The UE may read the system information of the satellite information based on the triggering event that occurred. The system information reading of the satellite information may include at least ephemeris information. In some cases, the system information reading of the satellite information may (additionally) include the epoch time (e.g., the number of seconds that have passed since 12:00 noon Greenwich Mean Time (GMT) on January 1, 1970, excluding leap seconds), SMTC (measurement timing configuration based on SSB (synchronization signal block)), downlink polarization information, service cell stop time and reference position triggered by idle mode measurements in non-geostationary orbit (NGSO) fixed cells (if applicable), feeder link delays of neighboring cells for neighboring cell SMTC adjustment (e.g., common timing advance and K_MAC (e.g., an indication of the amount of misalignment between downlink and uplink frame timing on the network (e.g., base station) side), separate validity timing, and the reference position of the downlink frame timing. timer, target cell ephemeris information, epoch time of ephemeris, common timing advance, validity timer information for target cell mobility, downlink and uplink polarization information, K_offset and K_MAC (e.g., to determine UE-base station round trip time and perform RACH to the target cell). In some cases, the system information reading of satellite information may include one or more of the following: a master information block (MIB), a system information block 1 (SIB1), or SIBx. In some cases, reading the system information of satellite information based on the occurrence of a triggering event may include the UE reading the system information of the UE's serving cell. In some cases, the system information of the UE's serving cell may include system information of satellite information of a neighboring cell or a target cell.
[0192] In some cases, the network behavior may include the network periodically updating the system information of the satellite information. In this case, to determine that a triggering event for the system information reading of the satellite information has occurred, the UE may determine that a time period has passed since a previous reading of the system information reading of the satellite information. The time period may be based at least in part on a period of network updates of the system information reading of the satellite information. The period of network updates may be defined by a 3GPP standard. In some cases, the time period may be based at least in part on a scaling period of network updates of the system information reading of the satellite information. The scaling period may be a product of a scaling factor and a period of network updates. The scaling factor may be defined by a 3GPP standard.
[0193] In some cases, the network behavior may include configuring the measurement object to the UE. In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine to read the system information of the satellite information in preparation for the measurement object.
[0194] In some cases, the network behavior may include configuring a handover to the UE. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information in preparation for the handover. In some cases, in order to read system information of satellite information based on the occurrence of a triggering event, the UE may read system information of satellite information measured by the target cell from the source serving cell for handover purposes.
[0195] In some cases, the UE behavior may include performing a radio resource control (RRC) reestablishment after a radio link failure (RLF). In this case, in order to determine that a triggering event for reading system information for satellite information has occurred, the UE may determine to read system information of satellite information for RRC reestablishment of the target cell on the target cell.
[0196] In some cases, the UE behavior may include performing serving cell measurement or neighboring cell measurement. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information before performing serving cell measurement or neighboring cell measurement.
[0197] In some embodiments, the UE behavior may include performing a random access channel (RACH) transmission. In this case, in order to determine that a triggering event for reading system information of satellite information has occurred, the UE may determine to read system information of satellite information before performing a RACH transmission.
[0198] In some cases, the channel condition may include that the serving cell signal quality drops below a threshold. In this case, in order to determine that a triggering event for reading the system information of the satellite information has occurred, the UE may determine that the serving cell signal quality is less than the threshold. In this case, in order to read the system information of the satellite information based on the occurrence of the triggering event, the UE may read the system information of the satellite information of the serving cell in preparation for mobility measurement.
