  • mMTC massive machine type communications
  • 5GS 5G system
  • RAT radio access technology
  • eMBB enhanced mobile broadband
  • URLLC ultra-reliable and low latency communication
  • 5G includes the New Radio (NR) access stratum interface and the 5G Core Network (5GC).
  • NR New Radio
  • 5GC 5G Core Network
  • the NR physical and higher layers reuse parts of the LTE specification and add needed components when motivated by the new use cases.
  • 3GPP also began preparing NR for operation in a Non- Terrestrial Network (NTN).
  • NTN Non- Terrestrial Network
  • the work was performed within the study item “NR to support Non-Terrestrial Networks” and resulted in 3GPP TR 38.811. See, 3GPP TR 38.811, Study on New Radio (NR) to support non-terrestrial networks.
  • NR New Radio
  • the work to prepare NR for operation in an NTN network continued with the study item “Solutions for NR to support Non-Terrestrial Network,” which resulted in 3GPP TR 38.821.
  • a satellite radio access network usually includes: a satellite that refers to a space-borne platform; an earth-based gateway that connects the satellite to a base station or a core network, depending on the choice of architecture; a feeder link that refers to the link between a gateway and a satellite; and an access link that refers to the link between a satellite and a UE.
  • a satellite may be categorized as low earth orbit (LEO), medium earth orbit (MEO), or geostationary earth orbit (GEO) satellite, as follows: LEO: typical heights ranging from 250 – 1,500 km, with orbital periods ranging from 90 – 120 minutes. MEO: typical heights ranging from 5,000 – 25,000 km, with orbital periods ranging from 3 – 15 hours. GEO: height at about 35,786 km, with an orbital period of 24 hours.
  • LEO typical heights ranging from 250 – 1,500 km, with orbital periods ranging from 90 – 120 minutes.
  • MEO typical heights ranging from 5,000 – 25,000 km, with orbital periods ranging from 3 – 15 hours.
  • GEO height at about 35,786 km, with an orbital period of 24 hours.
  • the significant orbit height means that satellite systems are characterized by a path loss that is significantly higher than what is expected in TNs.
  • a communication satellite typically generates several beams over a given area.
  • the footprint of a beam is usually in an elliptic shape, which has been traditionally considered as a cell.
  • the footprint of a beam is also often referred to as a spotbeam.
  • the spotbeam may move over the earth surface with the satellite movement or may be earth fixed with some beam pointing mechanism used by the satellite to compensate for its motion.
  • the size of a spotbeam depends on the system design, which may range from tens of kilometers to a few thousands of kilometers.
  • FIGURE 1 illustrates an example architecture of a satellite network with bent pipe transponders.
  • Ephemeris data (sometimes referred to as just “ephemeris”) is data that allows a UE (or other entity) to determine a satellite’s position and velocity.
  • the ephemeris data contains parameters related to the satellite’s orbit.
  • ephemeris data should be provided to the UE such as, for example, to assist with pointing a directional antenna (or an antenna beam) towards the satellite and to calculate a correct Timing Advance (TA) and Doppler shift.
  • TA Timing Advance
  • ephemeris data will be broadcast in the system information (SI) in each cell, included in an NTN specific System Information Block (SIB), which is labeled SIB19 in NR NTN and SIB31 IoT NTN.

  • Exactly which set of parameters is chosen can be decided by the user and/or network provider, and many different representations are possible.
  • a choice of parameters used often in astronomy is the set (a, ⁇ , i, ⁇ , ⁇ , t).
  • the semi-major axis a and the eccentricity ⁇ describe the shape and size of the orbit ellipse;
  • the inclination i, the right ascension of the ascending node ⁇ , and the argument of periapsis ⁇ determine its position in space, and the epoch t determines a reference time (e.g. the time when the satellites moves through periapsis).
  • FIGURE 2 illustrate a set of parameters.
  • the Two-Line Elements use mean motion n and mean anomaly M instead of a and t.
  • a completely different set of parameters is the position and velocity vector (x, y, z, v x , v y , v z ) of a satellite. These are sometimes called orbital state vectors. They can be derived from the orbital elements and vice versa, since the information they contain is equivalent. All these formats (and many others) are possible choices for the format of ephemeris data to be used in NTN.
  • An aspect discussed during the 3GPP study item and captured in 3GPP TR 38.821 is the validity time of ephemeris data.
  • NTN-Specific Information in SI Due to the special operating conditions in a NTN, the SI broadcast in an NTN cell has to include NTN-specific information.
  • a new SIB (SIB19) is introduced in NR NTN that contains NTN-specific information.
  • the new SIB31 more or less corresponds to SIB19 in NR NTN.

  • ⁇ Reporting configuration A list of reporting configurations where there can be one or multiple reporting configurations per measurement object. Each measurement reporting configuration consists of the following: o Reporting criterion: The criterion that triggers the UE to send a measurement report. This can either be periodical or a single event description.
  • o RS type The RS that the UE uses for beam and cell measurement results (Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block or Channel State Information-Reference Signal (CSI-RS)).
  • o Reporting format The quantities per cell and per beam that the UE includes in the measurement report (e.g., Reference Signal Received Power (RSRP)) and other associated information such as the maximum number of cells and the maximum number beams per cell to report.

  • Availability in a cell is also used to implicitly or explicitly indicate that the cell is an NTN cell) and are associated with an indication different from PCI or carrier frequency, e.g., satellite identifier (ID).
  • This indication is similarly added to the corresponding entry in InterFreqNeighCellInfo and/or IntraFreqNeighCellInfo, respectively, so that UE can identify the required satellite assistance information for the target NTN cell.
  • Changes of the dynamic satellite assistance information included as an extension in any legacy SIB should be exempt from the typical SI update mechanisms, which involves sending SI update notifications to UEs in the cell by repeated transmissions of a so-called Short Message, which is a Downlink Control Information (DCI) message sent on the PDCCH addressed to the Paging-Radio Network Temporary Identifier (P-RNTI) (i.e., the RNTI otherwise used for paging of UEs).

  • SIB19 (in NR) and/or SIB31 (in LTE) are used to broadcast the neighbor satellite assistance information also in TN cells. This is true despite the potential problem associated with it.
  • an NTN capable legacy UE may interpret the existence of SIB19 (in NR) or SIB31 (in LTE) as an indication of that the cell is an NR NTN cell or an IoT cell.
  • SIB19 (in NR) and/or SIB31 (in LTE) in the embodiments described herein is motivated by the reasoning that the advantage of being able to reuse existing specified functionality outweighs the disadvantage.
  • the legacy UEs implementing NR NTN and/or IoT NTN functionality in accordance with Release 17 of the 3GPP standard can be expected to be very few, and the ones that may be produced can be expected to soon be replaced by superior models implementing later releases of the 3GPP standard and potentially more streamlined hardware (e.g., smaller and more energy efficient hardware).
  • the potential problem associated with usage of SIB19 in an NR NTN cell may possibly never occur since the NR stage 2 specification for NR (i.e., 3GPP TS 38.300 version 17.3.0, Section 16.14.3.1) states that “The UE can determine the network type (terrestrial or non-terrestrial) implicitly by the existence of cellBarredNTN in SIB1”.
  • SIB19 in NR
  • SIB31 in LTE
  • the relevant satellite assistance information would instead be placed in legacy SIB(s), this would force such a UE to frequently reacquire this(these) legacy SIB(s), which, due to the potentially extensive content of this(these) legacy SIB(s), will cause undesirable overhead (e.g. in terms of processing and energy consumption) in the UE.
  • SIB19 in NR
  • SIB31 in LTE
  • usage of these SIBs should be different from their usage in NR NTN and IoT NTN.
  • a major difference between a TN cell and an NTN cell is that a TN cell is not served by a satellite. As a consequence, no satellite assistance information is needed for the serving cell.
  • ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 are associated with the serving cell (disregarding the lateNonCriticalExtension field, whose purpose is to enable future extensions, and for which no content has yet been specified).
  • ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs are thus the only IEs that are relevant when SIB19 is broadcast in a TN cell, while the other fields (which are all optional) are of no use and should be omitted.
  • ntn-Config Provides parameters needed for the UE to access NR via NTN access such as Ephemeris data, common TA parameters, k_offset, validity duration for UL sync information and epoch.
  • the serving cell is a TN cell
  • the field is absent in the information associated with the serving cell. Otherwise the field is optionally present (need R).
  • the following sentence could advantageously be added to some of the other SIB19 field descriptions (for the fields t-Service-r17, referenceLocation-r17 and distanceThreshold-r17) in 3GPP TS 38.331 version 17.3.0: “The field is absent when the serving cell is a TN cell.”
  • a new conditional presence tag could be introduced and associated with the ntn-Config-r17 field in the serving cell information in SIB19.
  • This new conditional presence tag could be called “NTN-cell”, for example, and would mean that the field is absent if the serving cell is a TN cell, otherwise the field is optionally present (need R).
  • This new SIB could be tailored for this purpose such as, for example, by reusing the neighbor cell/satellite related fields of SIB19, while omitting the fields related to the serving cell.
  • ntn-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs have been replaced by a single new list denoted as ntn-NeighCellConfigEnhancedList-r18.
  • a UE is not expected to use the satellite assistance information for a neighbor cell to calculate its UE specific TA, but rather for autonomous adjustments of the SMTC associated with the neighbor cell (and possibly for determination of a receive beam or adjustment of a directional antenna, in case the UE uses such features for NTN monitoring).
  • This usage of the satellite assistance information can be performed with much lower accuracy of the satellite assistance information (i.e., greater errors in the satellite assistance information are tolerable) than UE autonomous TA calculation.
  • a longer validity time can be configured for the satellite assistance information associated with a neighbor cell than for the satellite assistance information associated with the serving cell.
  • the satellite assistance information for the serving cell is omitted when SIB19 is broadcast in a TN cell (because the serving cell is not served by a satellite)
  • this property could be better utilized if the current maximum configurable value of the validity time (i.e., the ntn-UlSyncValidityDuration-r17 field in the NTN-Config-r17 IE), which is 900 seconds in 3GPP TS 38.331 version 17.3.0, were to be increased (e.g., by adding one or more configurable values greater than 900 seconds such as, for example, to 1800 seconds).
  • the concerned fields are all included in the NTN-Config-r17 IE, and they all have the following sentence in their respective field description: “This field is excluded when determining changes in system information, i.e. changes to ⁇ field name> should neither result in system information change notifications nor in a modification of valueTag in SIB1.” In the above quoted sentence, “ ⁇ field name>“ represents the respective one of the concerned field names.
  • the concerned fields are: epochTime-r17 ntn-UlSyncValidityDuration-r17 ta-Common-r17 (in TA-Info-r17) ta-CommonDrift-r17 (in TA-Info-r17) ta-CommonDriftVariant-r17 (in TA-Info-r17) ephemerisInfo-r17
  • the exemption of these fields serves to avoid frequent SI change notifications, which would consume DL transmission resources as well as processing resources, and would have a negative impact on the UEs’ energy consumption.
  • Such notifications would also be superfluous, as a UE’s reacquisition of SIB19 in an NTN cell anyway is governed by the value of the ntn-UlSyncValidityDuration-r17 field and its internal timer T430.
  • SIB19 is broadcast in a TN cell, the situation becomes slightly different, because the neighbor NTN cells are served by moving satellites (except in the case of a geostationary satellite, which is not moving in relation to the TN cell), while the TN cell is not.

  • Yet another alternative could be to exclude changes of the ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 from the SI changes that trigger SI change notification and SIB19 valueTag update, but not introduce any new parameter in SIB19.

Description

SATELLITE ASSISTANCE INFORMATION PROVISIONING FROM A TERRESTERIAL NETWORK TECHNICAL FIELD The present disclosure relates, in general, to wireless communications and, more particularly, systems and methods for satellite assistance information provisioning from a Terrestrial Network (TN). BACKGROUND In 3GPP Release 8, the Evolved Packet System (EPS) was specified. EPS is based on the Long-Term Evolution (LTE) radio network and the Evolved Packet Core (EPC). It was originally intended to provide voice and mobile broadband (MBB) services but has continuously evolved to broaden its functionality. Since Release 13, Narrowband-Internet of Things (NB-IoT) and Long Term Evolution for Machines (LTE-M) are part of the LTE specifications and provide connectivity to massive machine type communications (mMTC) services. In 3GPP Release 15, the first release of the 5G system (5GS) was specified. This is a new generation’s radio access technology (RAT) intended to serve use cases such as enhanced mobile broadband (eMBB), ultra-reliable and low latency communication (URLLC) and mMTC. 5G includes the New Radio (NR) access stratum interface and the 5G Core Network (5GC). The NR physical and higher layers reuse parts of the LTE specification and add needed components when motivated by the new use cases. One such component is the introduction of a sophisticated framework for beam forming and beam management to extend the support of the 3GPP technologies to a frequency range going beyond 6 GHz. In Release 15, 3GPP also began preparing NR for operation in a Non- Terrestrial Network (NTN). The work was performed within the study item “NR to support Non-Terrestrial Networks” and resulted in 3GPP TR 38.811. See, 3GPP TR 38.811, Study on New Radio (NR) to support non-terrestrial networks. In Release 16, the work to prepare NR for operation in an NTN network continued with the study item “Solutions for NR to support Non-Terrestrial Network,” which resulted in 3GPP TR 38.821. The Release 16 study item resulted in a Work Item being agreed for NR in Release 17, “Solutions for NR to support non-terrestrial networks (NTN)”, which is described in the Work Item Description RP-193234. See, TS 38.304 v17.3.0, NR; User Equipment (UE) procedures in idle mode and in RRC Inactive state (Release 17). A satellite radio access network usually includes: a satellite that refers to a space-borne platform; an earth-based gateway that connects the satellite to a base station or a core network, depending on the choice of architecture; a feeder link that refers to the link between a gateway and a satellite; and an access link that refers to the link between a satellite and a UE. Depending on the orbit altitude, a satellite may be categorized as low earth orbit (LEO), medium earth orbit (MEO), or geostationary earth orbit (GEO) satellite, as follows: LEO: typical heights ranging from 250 – 1,500 km, with orbital periods ranging from 90 – 120 minutes. MEO: typical heights ranging from 5,000 – 25,000 km, with orbital periods ranging from 3 – 15 hours. GEO: height at about 35,786 km, with an orbital period of 24 hours. The significant orbit height means that satellite systems are characterized by a path loss that is significantly higher than what is expected in TNs. To overcome pathloss, it is often required that the access and feeder links are operated in line of sight (LoS) conditions, and that the UE is equipped with an antenna offering high beam directivity. A communication satellite typically generates several beams over a given area. The footprint of a beam is usually in an elliptic shape, which has been traditionally considered as a cell. The footprint of a beam is also often referred to as a spotbeam. The spotbeam may move over the earth surface with the satellite movement or may be earth fixed with some beam pointing mechanism used by the satellite to compensate for its motion. The size of a spotbeam depends on the system design, which may range from tens of kilometers to a few thousands of kilometers. FIGURE 1 illustrates an example architecture of a satellite network with bent pipe transponders. In comparison to the beams observed in a terrestrial network, the NTN beam may be very wide and cover an area outside of the area defined by the served cell. Beams covering adjacent cells will overlap and cause significant levels of intercell interference. To overcome the large levels of interference, a typical approach is for NTN to configure different cells with different carrier frequencies and polarization modes. Ephemeris data (sometimes referred to as just “ephemeris”) is data that allows a UE (or other entity) to determine a satellite’s position and velocity. For example, the ephemeris data contains parameters related to the satellite’s orbit. There are several different formats defined for ephemeris data. In 3GPP TR 38.821, it has been captured that ephemeris data should be provided to the UE such as, for example, to assist with pointing a directional antenna (or an antenna beam) towards the satellite and to calculate a correct Timing Advance (TA) and Doppler shift. See, RP-181370, Study on solutions evaluation for NR to support non-terrestrial Network. In NR, NTN and Internet of Things (IoT) NTN, ephemeris data will be broadcast in the system information (SI) in each cell, included in an NTN specific System Information Block (SIB), which is labeled SIB19 in NR NTN and SIB31 IoT NTN. A satellite orbit can be fully described using six parameters. Exactly which set of parameters is chosen can be decided by the user and/or network provider, and many different representations are possible. For example, a choice of parameters used often in astronomy is the set (a, ε, i, Ω, ω, t). Here, the semi-major axis a and the eccentricity ε describe the shape and size of the orbit ellipse; the inclination i, the right ascension of the ascending node Ω, and the argument of periapsis ω determine its position in space, and the epoch t determines a reference time (e.g. the time when the satellites moves through periapsis). FIGURE 2 illustrate a set of parameters. As an example of a different parametrization, the Two-Line Elements (TLEs) use mean motion n and mean anomaly M instead of a and t. A completely different set of parameters is the position and velocity vector (x, y, z, vx, vy, vz) of a satellite. These are sometimes called orbital state vectors. They can be derived from the orbital elements and vice versa, since the information they contain is equivalent. All these formats (and many others) are possible choices for the format of ephemeris data to be used in NTN. An aspect discussed during the 3GPP study item and captured in 3GPP TR 38.821 is the validity time of ephemeris data. Predictions of satellite positions in general degrade with increasing age of the ephemeris data used due to atmospheric drag, maneuvering of the satellite, imperfections in the orbital models used, etc. Therefore, the publicly available TLE data are updated quite frequently. For example, the update frequency depends on the satellite and its orbit and ranges from weekly to multiple times a day for satellites on very low orbits, which are exposed to strong atmospheric drag and need to perform correctional maneuvers often. Even more frequent updates will be used in NR NTN (and IoT NTN) to allow the UE to determine/predict the satellite’s position (and velocity) accurately enough to satisfy the requirements in NTN such as, for example, to enable a UE to calculate an accurate enough UE-specific TA. NTN-Specific Information in SI Due to the special operating conditions in a NTN, the SI broadcast in an NTN cell has to include NTN-specific information. To serve this purpose, a new SIB (SIB19) is introduced in NR NTN that contains NTN-specific information. In IoT NTN, the new SIB31 more or less corresponds to SIB19 in NR NTN. In 3GPP TS 38.331 version 17.0.0, SIB19 is defined in ASN.1 code in 3GPP TS 38.331 version 17.0.0. Furthermore, the NTN-Config-r17 IE is defined in ASN.1 code in the same specification. The EphemerisInfo IE is defined in ASN.1 code in the same specification. Configuration for Measurement Reporting In a wireless network, the UE needs to measure the signal quality of the cell to perform cell selection or cell re-selection. While the UE is in RRC_Connected mode, it will report the measured results to the network. The above procedures are performed based on the measurement configuration from the network, which includes the following parameters: ^ Measurement objects: A list of objects on which the UE shall perform the measurements. ^ Reporting configuration: A list of reporting configurations where there can be one or multiple reporting configurations per measurement object. Each measurement reporting configuration consists of the following: o Reporting criterion: The criterion that triggers the UE to send a measurement report. This can either be periodical or a single event description. o RS type: The RS that the UE uses for beam and cell measurement results (Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block or Channel State Information-Reference Signal (CSI-RS)). o Reporting format: The quantities per cell and per beam that the UE includes in the measurement report (e.g., Reference Signal Received Power (RSRP)) and other associated information such as the maximum number of cells and the maximum number beams per cell to report. In case of conditional reconfiguration, each configuration consists of the following: o Execution criteria: The criteria the UE uses for conditional reconfiguration execution. o Reference Signal (RS) type: The RS that the UE uses for obtaining beam and cell measurement results (SS/PBCH block- based or CSI-RS-based), used for evaluating conditional reconfiguration execution condition. ^ Measurement identities: For measurement reporting, a list of measurement identities where each measurement identity links one measurement object with one reporting configuration. ^ Quantity configurations: The quantity configuration defines the measurement filtering configuration used for all event evaluation and related reporting, and for periodical reporting of that measurement. ^ Measurement gaps: Periods that the UE may use to perform measurements. A UE in RRC_CONNECTED maintains a measurement object list, a reporting configuration list, and a measurement identities list according to the 3GPP specification. RAN4 agreements The latest RAN4 agreement include: ^ Define “availability of valid target satellite information as side condition” o Parameters listed in R2-2201884 are defined as the required target satellite information for measurement and mobility. ^ For measurement ^ Ephemeris ^ Epoch time ^ SMTCs ^ DL polarization information ^ Serving cell stop time and reference location for IDLE mode measurement trigger in NGSO fixed cell, if applicable ^ Under RAN1 discussion: o Feeder link delay (i.e., common TA and K_MAC) of the neighbor cell should also be provided to UE for neighbor cell SMTC adjustment o separate validity timers ^ For mobility ^ Target cell Ephemeris information ^ Epoch time of the ephemeris ^ Common TA ^ Validity timer information for target cell mobility ^ DL and UL Polarization information ^ K_offset ^ Kmac (to determine UE-gNB RTT and perform RACH to target) ^ If the side condition is not met, o Requirements are not applied, i.e. extra delay won’t be explicitly defined o Note: UE is allowed not to perform RRM measurement [and reporting] if the side condition is not met before acquiring new ephemeris information There currently exist certain challenge(s), however. For example, in NTN, satellite assistance information for neighbor cells may be optionally included in SIB19 (in NR NTN) or SIB31 (in IoT NTN). This includes satellite ephemeris and related information (ntn-Config-r17) but also the carrier frequency (carrierFreq-r17) or PCI (physCellId-r17) According to the late RAN4 agreements, which has been captured in 3GPP TR 38.300, the UE is not required to perform neighbor cell measurements if the corresponding satellite assistance information is not present. This applies to both RRC_CONNECTED and RRC_IDLE modes. In order to facilitate mobility from terrestrial networks to NTN networks, the TN network need to provision the satellite information to the UEs. In RAN2 there is an ongoing discussion on whether/how it should be possible to transmit SIB19 from a TN cell. However, this would imply that the TN cell is considered as an NTN cell since it is specified that the presence of SIB19 in cell indicates implicitly that the cell supports NTN. Thus, a new mechanism is required to provide satellite assistance information (provided in SINB19 in an NTN cell) in a TN cell. SUMMARY Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. For example, according to certain embodiments, methods and systems are disclosed for providing the essential parts of SIB19 in NR NTN and SIB31 in IoT NTN to make measurements and enable mobility. According to certain embodiments, a method by a UE for receiving satellite assistance information from a TN includes receiving satellite assistance information from a network node serving the UE in a cell associated with the TN. The satellite assistance information is associated with a satellite that is a candidate for serving the UE in a cell associated with a Non-Terrestrial Network, NTN.

Any feature of any of the embodiments disclosed herein may be applied to any other embodiment, wherever appropriate. Likewise, any advantage of any of the embodiments may apply to any other embodiments, and vice versa. Other objectives, features and advantages of the enclosed embodiments will be apparent from the following description. As used herein, ‘node’ can be a network node or a UE. Examples of network nodes are NodeB, base station (BS), multi-standard radio (MSR) radio node such as MSR BS, eNodeB (eNB), gNodeB (gNB), Master eNB (MeNB), Secondary eNB (SeNB), integrated access backhaul (IAB) node, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), Central Unit (e.g. in a gNB), Distributed Unit (e.g. in a gNB), Baseband Unit, Centralized Baseband, C-RAN, access point (AP), transmission points, transmission nodes, Remote Radio Unit (RRU), Remote Radio Head (RRH), nodes in distributed antenna system (DAS), core network node (e.g. Mobile Switching Center (MSC), Mobility Management Entity (MME), etc.), Operations & Maintenance (O&M), Operations Support System (OSS), Self Organizing Network (SON), positioning node (e.g. E-SMLC), etc. Another example of a node is user equipment (UE), which is a non-limiting term and refers to any type of wireless device communicating with a network node and/or with another UE in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, vehicular to vehicular (V2V), machine type UE, MTC UE or UE capable of machine to machine (M2M) communication, Personal Digital Assistant (PDA), Tablet, mobile terminals, smart phone, laptop embedded equipment (LEE), laptop mounted equipment (LME), Unified Serial Bus (USB) dongles, etc. In some embodiments, generic terminology, “radio network node” or simply “network node (NW node)”, is used. It can be any kind of network node which may comprise base station, radio base station, base transceiver station, base station controller, network controller, evolved Node B (eNB), Node B, gNodeB (gNB), relay node, access point, radio access point, Remote Radio Unit (RRU) Remote Radio Head (RRH), Central Unit (e.g. in a gNB), Distributed Unit (e.g. in a gNB), Baseband Unit, Centralized Baseband, C-RAN, access point (AP), etc. The term radio access technology (RAT), may refer to any RAT such as, for example, Universal Terrestrial Radio Access Network (UTRA), Evolved Universal Terrestrial Radio Access Network (E-UTRA), narrow band internet of things (NB- IoT), WiFi, Bluetooth, next generation RAT, NR, 4G, 5G, etc. Any of the equipment denoted by the terms node, network node or radio network node may be capable of supporting a single or multiple RATs. The term signal or radio signal used herein can be any physical signal or physical channel. Examples of DL physical signals are reference signal (RS) such as Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Channel State Information-Reference Signal (CSI-RS), Demodulation Reference Signal (DMRS) signals in SS/PBCH block (SSB), discovery reference signal (DRS), Cell Specific Reference Signal (CRS), Positioning Reference Signal (PRS), etc. RS may be periodic. For example, RS occasions carrying one or more RSs may occur with certain periodicity such as, for example, 20 ms, 40 ms, etc. The RS may also be aperiodic. Each SSB carries NR-PSS, NR-SSS and NR-PBCH in four successive symbols. One or multiple SSBs are transmit in one SSB burst which is repeated with certain periodicity such as, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, and 160 ms. The UE is configured with information about SSB on cells of certain carrier frequency by one or more SS/PBCH block measurement timing configuration (SMTC) configurations. The SMTC configuration comprising parameters such as SMTC periodicity, SMTC occasion length in time or duration, SMTC time offset with regard to reference time (e.g., serving cell’s SFN), etc. Therefore, SMTC occasion may also occur with certain periodicity such as, for example, 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, and 160 ms. Examples of uplink (UL) physical signals are reference signal such as SRS, DMRS etc. The term physical channel refers to any channel carrying higher layer information such as, for example, data, control, etc. Examples of physical channels are Physical Broadcast Channel (PBCH), Narrowband PBCH (NPBCH), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), shortened PUCCH (sPUCCH), shortened PDSCH (sPDSCH), shortened PUCCH (sPUCCH), shortened PUSCH (sPUSCH), MTC PDCCH (MPDCCH), narrowband PDCCH (NPDCCH), Narrowband PDSCH (NPDSCH), E-PDCCH, Narrowband PUSCH (NPUSCH), etc. The term time resource used herein may correspond to any type of physical resource or radio resource expressed in terms of length of time. Examples of time resources are: symbol, time slot, subframe, radio frame, transmission time interval (TTI), interleaving time, slot, sub-slot, mini-slot, system frame number (SFN) cycle, hyper-SFN (H-SFN) cycle etc. It may be recognized that, in NR, a UE will see cells and not necessarily satellites. While this disclosure talks about serving and neighbor satellites, it may be understood that, as used herein, the term serving satellite is used to refer to a satellite broadcasting the cell that is serving the UE. Likewise, the term neighbor satellite is used to refer to a satellite that is broadcasting the cell that is neighbor cell for the UE. According to certain embodiments, methods and systems are disclosed for providing the essential parts of SIB19 in NR NTN and SIB31 in IoT NTN to make measurements and enable mobility. For example, in various particular embodiments, a proposed height dependent measurement reporting configuration introduces one or more measurement reporting configuration for aerial UEs within certain height range and describes how the configurations are adopted, as well as some candidate parameters which could be included in the configuration sets. Also other approaches are presented on how the measurement and reporting of the UE can be controlled via the RRC configuration. More specifically, according to certain embodiments, the essential information for performing neighbor cell measurements in RRC_INACTIVE and RRC_IDLE state is acquired from SIB19 broadcast in an NR NTN cell. In accordance with certain embodiments, it is broadcast in an NR TN cell in SIB2 and/or SIB3 and/or SIB4 together with a list of Physical Cell Indicators (PCIs) and/or carrier frequencies. In an LTE TN cell, the essential information is, in accordance with the proposed methods, systems, and techniques, broadcast in SIB3 and/or SIB4 and/or SIB5. In NR TN cells, satellite assistance information for an NTN neighbor cell may be transmitted in a new or different (SIB(s). For example, SIB2 may include common information relevant for intra-frequency, inter-frequency, and inter-RAT NTN neighbors. Similarly, SIB3 may be used in case the NTN neighbor operates in the same frequency as the serving cell. There may be overlapping frequency bands between TN and NTN. See, TS 38.304. Finally, SIB4 can be used for inter-frequency NTN neighbors and SIB5 for inter-RAT NTN neighbors (e.g., LTE NTN). The following is an example of how satellite assistance information can be included in SIB4 in NR, (using the SIB4 ASN.1 definition in 3GPP TS 38.331 version 17.3.0 as the baseline and showing changes to the baseline text using bold and underline): -- ASN1START -- TAG-SIB4-START SIB4 ::= SEQUENCE { interFreqCarrierFreqList InterFreqCarrierFreqList, lateNonCriticalExtension OCTET STRING OPTIONAL, ..., [[ interFreqCarrierFreqList-v1610 InterFreqCarrierFreqList-v1610 OPTIONAL -- Need R ]], [[ interFreqCarrierFreqList-v1700 InterFreqCarrierFreqList-v1700 OPTIONAL -- Need R ]], [[ interFreqCarrierFreqList-v1720 InterFreqCarrierFreqList-v1720 OPTIONAL -- Need R ]], [[ interFreqCarrierFreqList-v1730 InterFreqCarrierFreqList-v1730 OPTIONAL -- Need R ]], [[ NeighCellConfigList-r18 NTN- r17 OPTIONAL, -- Need R NeighCellConfigListExt-r18 NTN- NeighCellConfigList-r17 OPTIONAL -- Need R ]] } InterFreqCarrierFreqList ::= SEQUENCE (SIZE (1..maxFreq)) OF InterFreqCarrierFreqInfo InterFreqCarrierFreqList-v1610 ::= SEQUENCE (SIZE (1..maxFreq)) OF InterFreqCarrierFreqInfo-v1610 InterFreqCarrierFreqList-v1700 ::= SEQUENCE (SIZE (1..maxFreq)) OF InterFreqCarrierFreqInfo-v1700 InterFreqCarrierFreqList-v1720 ::= SEQUENCE (SIZE (1..maxFreq)) OF InterFreqCarrierFreqInfo-v1720 InterFreqCarrierFreqList-v1730 ::= SEQUENCE (SIZE (1..maxFreq)) OF InterFreqCarrierFreqInfo-v1730 InterFreqCarrierFreqInfo ::= SEQUENCE { dl-CarrierFreq ARFCN-ValueNR, frequencyBandList MultiFrequencyBandListNR-SIB OPTIONAL, -- Cond Mandatory frequencyBandListSUL MultiFrequencyBandListNR-SIB OPTIONAL, -- Need R nrofSS-BlocksToAverage INTEGER (2..maxNrofSS-BlocksToAverage) OPTIONAL, -- Need S absThreshSS-BlocksConsolidation ThresholdNR OPTIONAL, -- Need S smtc SSB-MTC OPTIONAL, -- Need S ssbSubcarrierSpacing SubcarrierSpacing, ssb-ToMeasure SSB- ToMeasure OPTIONAL, -- Need S deriveSSB-IndexFromCell BOOLEAN, ss-RSSI-Measurement SS-RSSI- Measurement OPTIONAL, -- Need R q-RxLevMin Q-RxLevMin, q-RxLevMinSUL Q-RxLevMin OPTIONAL, -- Need R q-QualMin Q-QualMin OPTIONAL, -- Need S p-Max P-Max OPTIONAL, -- Need S t-ReselectionNR T-Reselection, t-ReselectionNR-SF SpeedStateScaleFactors OPTIONAL, -- Need S threshX-HighP ReselectionThreshold, threshX-LowP ReselectionThreshold, threshX-Q SEQUENCE { threshX-HighQ ReselectionThresholdQ, threshX-LowQ ReselectionThresholdQ } OPTIONAL, -- Cond RSRQ cellReselectionPriority CellReselectionPriority OPTIONAL, -- Need R cellReselectionSubPriority CellReselectionSubPriority OPTIONAL, -- Need R q-OffsetFreq Q-OffsetRange DEFAULT dB0, interFreqNeighCellList InterFreqNeighCellList OPTIONAL, -- Need R interFreqExcludedCellList InterFreqExcludedCellList OPTIONAL, -- Need R ... } InterFreqCarrierFreqInfo-v1610 ::= SEQUENCE { interFreqNeighCellList-v1610 InterFreqNeighCellList-v1610 OPTIONAL, -- Need R smtc2-LP-r16 SSB-MTC2-LP-r16 OPTIONAL, -- Need R interFreqAllowedCellList-r16 InterFreqAllowedCellList-r16 OPTIONAL, -- Cond SharedSpectrum2 ssb-PositionQCL-Common-r16 SSB-PositionQCL- Relation-r16 OPTIONAL, -- Cond SharedSpectrum interFreqCAG-CellList-r16 SEQUENCE (SIZE (1..maxPLMN)) OF InterFreqCAG-CellListPerPLMN-r16 OPTIONAL -- Need R } InterFreqCarrierFreqInfo-v1700 ::= SEQUENCE { interFreqNeighHSDN-CellList-r17 InterFreqNeighHSDN-CellList-r17 OPTIONAL, -- Need R highSpeedMeasInterFreq-r17 ENUMERATED {true} OPTIONAL, -- Need R redCapAccessAllowed-r17 ENUMERATED {true} OPTIONAL, -- Need R ssb-PositionQCL-Common-r17 SSB-PositionQCL- Relation-r17 OPTIONAL, -- Cond SharedSpectrum interFreqNeighCellList-v1710 InterFreqNeighCellList-v1710 OPTIONAL -- Cond SharedSpectrum2 } InterFreqCarrierFreqInfo-v1720 ::= SEQUENCE { smtc4list-r17 SSB-MTC4List-r17 OPTIONAL -- Need R } InterFreqCarrierFreqInfo-v1730 ::= SEQUENCE { channelAccessMode2-r17 ENUMERATED {enabled} OPTIONAL -- Need R } InterFreqNeighHSDN-CellList-r17 ::= SEQUENCE (SIZE (1..maxCellInter)) OF PCI-Range InterFreqNeighCellList ::= SEQUENCE (SIZE (1..maxCellInter)) OF InterFreqNeighCellInfo InterFreqNeighCellList-v1610 ::= SEQUENCE (SIZE (1..maxCellInter)) OF InterFreqNeighCellInfo-v1610 InterFreqNeighCellList-v1710 ::= SEQUENCE (SIZE (1..maxCellInter)) OF InterFreqNeighCellInfo-v1710 InterFreqNeighCellInfo ::= SEQUENCE { physCellId PhysCellId, q-OffsetCell Q-OffsetRange, q-RxLevMinOffsetCell INTEGER (1..8) OPTIONAL, -- Need R q-RxLevMinOffsetCellSUL INTEGER (1..8) OPTIONAL, -- Need R q-QualMinOffsetCell INTEGER (1..8) OPTIONAL, -- Need R ... } InterFreqNeighCellInfo-v1610 ::= SEQUENCE { ssb-PositionQCL-r16 SSB-PositionQCL- Relation-r16 OPTIONAL -

In particular embodiments, for example, the above NTN-NeighCellConfig-r17 consists, instead of ntn-Config-r17 and may include a list of one or more parameters such as any one or more of (but not limited to): ^ NTN payload ephemeris ^ Epoch time of the ephemeris ^ SMTCs ^ DL and UL polarization information ^ Serving cell stop time ^ Reference location for NGSO fixed and moving cells, if applicable ^ Feeder link delay (i.e., common TA and Kmac) of the neighbor cell should also be provided to UE for neighbor cell SMTC adjustment ^ K_offset ^ Validity time information for ephemeris information, epoch time and Common TA parameters And instead of one PCI, a list of PCIs for which the list of parameters apply.

For example, SIB3 may include common information relevant for intra-frequency, inter-frequency, and inter-RAT NTN neighbors. Similarly, SIB4 may be used in case the NTN neighbor operates in the same frequency as the serving cell. Finally, SIB5 can be used for inter-frequency and/or inter-RAT NTN neighbors (e.g., NR NTN).In an alternative embodiment, the essential or relevant parts of the information contained in SIB19 (in NR) or SIB31 (in LTE) for each neighbor NTN satellite and /or cell are broadcast in a new SIB or in an existing SIB in a TN cell as an extension (wherein the utilized existing SIB is not a SIB whose presence (i.e. availability in a cell) is also used to implicitly or explicitly indicate that the cell is an NTN cell) and are associated with an indication different from PCI or carrier frequency, e.g., satellite identifier (ID). This indication is similarly added to the corresponding entry in InterFreqNeighCellInfo and/or IntraFreqNeighCellInfo, respectively, so that UE can identify the required satellite assistance information for the target NTN cell. Changes of the dynamic satellite assistance information included as an extension in any legacy SIB should be exempt from the typical SI update mechanisms, which involves sending SI update notifications to UEs in the cell by repeated transmissions of a so-called Short Message, which is a Downlink Control Information (DCI) message sent on the PDCCH addressed to the Paging-Radio Network Temporary Identifier (P-RNTI) (i.e., the RNTI otherwise used for paging of UEs). This is motivated by that the content is very dynamic and its validity is governed by timers (indicated as validity durations), which trigger interested (NTN capable) UEs to reacquire the information when needed. This concerns primarily (when included in the concerned embodiment) the fields epochTime-r17, ntn-UlSyncValidityDuration-r17, ta-Common-r17 (in TA-Info-r17), ta-CommonDrift-r17 (in TA-Info-r17), ta- CommonDriftVariant-r17 (in TA-Info-r17), and ephemerisInfo-r17, but it may also concern changes in the set of NTN neighbor cells, i.e. changes of which list items the NTN-NeighCellConfigList-r17 and NeighCellConfigListExt-v1720 IEs or the NeighCellConfigEnhancedList-r18 IE contain, i.e. additions and removals of list items, as well as changes of fields within a list item (such mechanisms are further elaborated in the examples using SIB19 discussed herein and those mechanisms may be reused when the satellite assistance information is included in a legacy TN SIB too). Using NR SIB19 (and/or LTE SIB31) The embodiments herein are described in terms of NR and SIB19, but similar concepts can be applied to LTE and SIB31 too. In some embodiments SIB19 (in NR) and/or SIB31 (in LTE) are used to broadcast the neighbor satellite assistance information also in TN cells. This is true despite the potential problem associated with it. For example, an NTN capable legacy UE may interpret the existence of SIB19 (in NR) or SIB31 (in LTE) as an indication of that the cell is an NR NTN cell or an IoT cell. The usage of SIB19 (in NR) and/or SIB31 (in LTE) in the embodiments described herein is motivated by the reasoning that the advantage of being able to reuse existing specified functionality outweighs the disadvantage. In addition, the legacy UEs implementing NR NTN and/or IoT NTN functionality in accordance with Release 17 of the 3GPP standard can be expected to be very few, and the ones that may be produced can be expected to soon be replaced by superior models implementing later releases of the 3GPP standard and potentially more streamlined hardware (e.g., smaller and more energy efficient hardware). Moreover, the potential problem associated with usage of SIB19 in an NR NTN cell may possibly never occur since the NR stage 2 specification for NR (i.e., 3GPP TS 38.300 version 17.3.0, Section 16.14.3.1) states that “The UE can determine the network type (terrestrial or non-terrestrial) implicitly by the existence of cellBarredNTN in SIB1”. Furthermore, the content of SIB19 (in NR) and SIB31 (in LTE) can be pruned from irrelevant information to streamline them for usage in TN cells, and since their contents are very dynamic and require frequent reacquisition by a UE required to maintain a valid copy of the information. If the relevant satellite assistance information would instead be placed in legacy SIB(s), this would force such a UE to frequently reacquire this(these) legacy SIB(s), which, due to the potentially extensive content of this(these) legacy SIB(s), will cause undesirable overhead (e.g. in terms of processing and energy consumption) in the UE. Usage of SIB19 (in NR) and/or SIB31 (in LTE) may, thus, potentially be advantageous, but to optimize network and UE operations, usage of these SIBs should be different from their usage in NR NTN and IoT NTN. A major difference between a TN cell and an NTN cell is that a TN cell is not served by a satellite. As a consequence, no satellite assistance information is needed for the serving cell. Looking at the ASN.1 definition of SIB19 in NR in 3GPP TS 38.331 version 17.3.0 (which is copied below for convenience), all fields except ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 are associated with the serving cell (disregarding the lateNonCriticalExtension field, whose purpose is to enable future extensions, and for which no content has yet been specified). The ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs are thus the only IEs that are relevant when SIB19 is broadcast in a TN cell, while the other fields (which are all optional) are of no use and should be omitted. (The referenceLocation-r17 and distanceThreshold-r17 fields could in principle be used also in a TN cell, but they were designed for usage in a pseudo-Earth-fixed cell and would be of little or no value in a TN cell.): -- ASN1START -- TAG-SIB19-START SIB19-r17 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Need R t-Service-r17 INTEGER (0..549755813887) OPTIONAL, -- Need R referenceLocation-r17 ReferenceLocation- r17 OPTIONAL, -- Need R distanceThresh-r17 INTEGER(0..65525) OPTIONAL, -- Need R ntn-NeighCellConfigList-r17 NTN- NeighCellConfigList-r17 OPTIONAL, -- Need R lateNonCriticalExtension OCTET STRING OPTIONAL, ..., [[ ntn-NeighCellConfigListExt-v1720 NTN- NeighCellConfigList-r17 OPTIONAL -- Need R ]] } NTN-NeighCellConfigList-r17 ::= SEQUENCE (SIZE(1..maxCellNTN-r17)) OF NTN-NeighCellConfig-r17 NTN-NeighCellConfig-r17 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Need R carrierFreq-r17 ARFCN-ValueNR OPTIONAL, -- Need R physCellId-r17 PhysCellId OPTIONAL -- Need R } -- TAG-SIB19-STOP -- ASN1STOP To support the above proposed configuration choice for SIB19, the following amendment of the text in section 5.2.2.4.21 in 3GPP TS 38.331 version 17.3.0 (which does not appropriately take broadcast of SIB19 in a TN cell into account) could be made (the text addition is shown with underline and bold): Upon receiving SIB19 in an NTN cell, the UE in RRC_CONNECTED shall: 1> start or restart T430 for serving cell with the timer value set to ntn-UlSyncValidityDuration for the serving cell from the subframe indicated by epochTime for the serving cell; NOTE: UE should attempt to re-acquire SIB19 before the end of the duration indicated by ntn-UlSyncValidityDuration and epochTime by UE implementation. A further beneficial amendment of the 3GPP specifications could be the following amendment to the field description of ntn-Config-r17 in the SIB19 field descriptions in 3GPP TS 38.331 version 17.3.0 (the text addition is shown with underline and bold): ntn-Config Provides parameters needed for the UE to access NR via NTN access such as Ephemeris data, common TA parameters, k_offset, validity duration for UL sync information and epoch. When the serving cell is a TN cell, the field is absent in the information associated with the serving cell. Otherwise the field is optionally present (need R). And in addition, the following sentence could advantageously be added to some of the other SIB19 field descriptions (for the fields t-Service-r17, referenceLocation-r17 and distanceThreshold-r17) in 3GPP TS 38.331 version 17.3.0: “The field is absent when the serving cell is a TN cell.” Alternatively, or in addition to the above amendments, a new conditional presence tag could be introduced and associated with the ntn-Config-r17 field in the serving cell information in SIB19. This new conditional presence tag could be called “NTN-cell”, for example, and would mean that the field is absent if the serving cell is a TN cell, otherwise the field is optionally present (need R). The following is an example where the above-described amendments and the new conditional presence tag all have been implemented in the ASN.1 definition and field descriptions for SIB1, using 3GPP TS 38.331 version 17.3.0 as the baseline (the text addition is shown with underline and bold): -- ASN1START -- TAG-SIB19-START SIB19-r17 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Cond NTN- cell t-Service-r17 INTEGER (0..549755813887) OPTIONAL, -- Need R referenceLocation-r17 ReferenceLocation-r17 OPTIONAL, -- Need R distanceThresh-r17 INTEGER(0..65525) OPTIONAL, -- Need R ntn-NeighCellConfigList-r17 NTN-NeighCellConfigList-r17 OPTIONAL, -- Need R lateNonCriticalExtension OCTET STRING OPTIONAL, ..., [[ ntn-NeighCellConfigListExt-v1720 NTN-NeighCellConfigList-r17 OPTIONAL -- Need R ]] } NeighCellConfigList-r17 ::= SEQUENCE (SIZE(1..maxCellNTN-r17)) OF NeighCellConfig-r17 NTN-NeighCellConfig-r17 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Need R carrierFreq-r17 ARFCN-ValueNR OPTIONAL, -- Need R physCellId-r17 PhysCellId OPTIONAL -- Need R } -- TAG-SIB19-STOP -- ASN1STOP SIB19 field descriptions a SIB19 field descriptions distanceThresh a Using a new SIB In some embodiments, a new SIB is introduced in NR (herein referred to as SIBxx) specifically for the purpose of providing neighbor NTN cell and satellite assistance information in a TN cell. This new SIB could be tailored for this purpose such as, for example, by reusing the neighbor cell/satellite related fields of SIB19, while omitting the fields related to the serving cell. An example ASN.1 definition of such a new SIB is illustrated below: -- ASN1START -- TAG-SIBxx-START SIBxx-r18 ::= SEQUENCE { ntn-NeighCellConfigList-r17 NTN- NeighCellConfigList-r17 OPTIONAL, -- Need R ntn-NeighCellConfigListExt-v1720 NTN- NeighCellConfigList-r17 OPTIONAL -- Need R lateNonCriticalExtension OCTET STRING OPTIONAL, ..., } NTN-NeighCellConfigList-r17 ::= SEQUENCE (SIZE(1..maxCellNTN-r17)) OF NTN-NeighCellConfig-r17 NTN-NeighCellConfig-r17 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Need R carrierFreq-r17 ARFCN-ValueNR OPTIONAL, -- Need R physCellId-r17 PhysCellId OPTIONAL -- Need R } -- TAG-SIBxx-STOP -- ASN1STOP All the previously described options for how updates of the NeighCellConfigList-r17 and NeighCellConfigListExt-v1720 IEs should be treated, such as, in terms of whether they should trigger SI change notifications and valueTag updates, or whether such changes should be indicated in the Short Message DCI conveying SI change notifications, can be reused for the SIBxx example above too. In another example ASN.1 definition, the ntn-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs have been replaced by a single new list denoted as ntn-NeighCellConfigEnhancedList-r18. -- ASN1START -- TAG-SIBxx-START SIBxx-r18 ::= SEQUENCE { ntn-NeighCellConfigEnhancedList-r18 NTN- NeighCellConfigEnhancedList-r18 OPTIONAL, -- Need R lateNonCriticalExtension OCTET STRING OPTIONAL, ..., } NTN-NeighCellConfigEnhancedList-r18 ::= SEQUENCE (SIZE(1..maxCellNTN-r18)) OF NTN-NeighCellConfigEnhanced-r18 NTN-NeighCellConfigEnhanced-r18 ::= SEQUENCE { ntn-Config-r17 NTN-Config-r17 OPTIONAL, -- Need R carrierFreqAndCellsNTN-List-r18 CarrierFreqAndCellsNTN-List-r18 OPTIONAL, -- Need R } CarrierFreqAndCellsNTN-List-r18 ::= SEQUENCE (SIZE(1..maxFreqAndCellsNTN-r18)) OF CarrierFreqAndCellsNTN-r18 CarrierFreqAndCellsNTN-r18 ::= SEQUENCE { carrierFreq-r17 ARFCN-ValueNR OPTIONAL, -- Need R ntn-NeighCells-r18 SEQUENCE (SIZE(1..maxCellNTN-r18)) OF PhysCellId OPTIONAL -- Need R } -- TAG-SIBxx-STOP -- ASN1STOP All the previously described options for how updates of the NeighCellConfigList-r17 and NeighCellConfigListExt-v1720 IEs should be treated, e.g., in terms of whether they should trigger SI change notifications and valueTag updates, or whether such changes should be indicated in the Short Message DCI conveying SI change notifications, can be reused for the ntn- NeighCellConfigEnhancedList-r18 IE in the above variant of SIBxx too. Validity of the SI According to certain embodiments (and as opposed to the case for satellite assistance information for the serving cell), a UE is not expected to use the satellite assistance information for a neighbor cell to calculate its UE specific TA, but rather for autonomous adjustments of the SMTC associated with the neighbor cell (and possibly for determination of a receive beam or adjustment of a directional antenna, in case the UE uses such features for NTN monitoring). This usage of the satellite assistance information can be performed with much lower accuracy of the satellite assistance information (i.e., greater errors in the satellite assistance information are tolerable) than UE autonomous TA calculation. As a consequence, a longer validity time can be configured for the satellite assistance information associated with a neighbor cell than for the satellite assistance information associated with the serving cell. When the satellite assistance information for the serving cell is omitted when SIB19 is broadcast in a TN cell (because the serving cell is not served by a satellite), this property could be better utilized if the current maximum configurable value of the validity time (i.e., the ntn-UlSyncValidityDuration-r17 field in the NTN-Config-r17 IE), which is 900 seconds in 3GPP TS 38.331 version 17.3.0, were to be increased (e.g., by adding one or more configurable values greater than 900 seconds such as, for example, to 1800 seconds). Another consequence is the potential use of coarser ephemeris information such as, for example, mean ephemeris information, which inherently holds valid for longer periods of time (in the order of weeks). Mean ephemeris information is presently transmitted in TLE format as part of SIB32 (LTE) assistance information for discontinuous coverage scenarios and could be similarly used for SMTC adjustments. Change of SI content According to 3GPP TS 38.331 version 17.3.0, the most dynamic content in SIB19 is exempt from the regular SI change notification mechanisms. That is, changes thereof trigger neither SI change notifications to be sent, nor modifications of the valueTag associated with SIB19. The concerned fields are all included in the NTN-Config-r17 IE, and they all have the following sentence in their respective field description: “This field is excluded when determining changes in system information, i.e. changes to <field name> should neither result in system information change notifications nor in a modification of valueTag in SIB1.” In the above quoted sentence, “<field name>“ represents the respective one of the concerned field names. The concerned fields are: epochTime-r17 ntn-UlSyncValidityDuration-r17 ta-Common-r17 (in TA-Info-r17) ta-CommonDrift-r17 (in TA-Info-r17) ta-CommonDriftVariant-r17 (in TA-Info-r17) ephemerisInfo-r17 The exemption of these fields serves to avoid frequent SI change notifications, which would consume DL transmission resources as well as processing resources, and would have a negative impact on the UEs’ energy consumption. Such notifications would also be superfluous, as a UE’s reacquisition of SIB19 in an NTN cell anyway is governed by the value of the ntn-UlSyncValidityDuration-r17 field and its internal timer T430. When SIB19 is broadcast in a TN cell, the situation becomes slightly different, because the neighbor NTN cells are served by moving satellites (except in the case of a geostationary satellite, which is not moving in relation to the TN cell), while the TN cell is not. As a result, the neighbor NTN cells will change frequently due to cell switches (triggered by changes in the feeder link or the serving satellite) and moving NTN cells. As a consequence, the list of neighbor NTN cells, as configured in the NTN-NeighCellConfigList-r17 IE and the ntn-NeighCellConfigListExt-v1720 IE will be relatively frequently updated. This motivates introduction of a mechanism serving to avoid changes in the set of NTN neighbor cells triggering SI change notifications to be sent (and updates of the valueTag associated with SIB19). Such changes include primarily changes of which list items the NTN-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt- v1720 IEs contain, i.e. additions and removals of list items, but also changes of any of the carrierFreq-r17 and physCellId-r17 fields within a list item (and the most dynamic fields of the ntn-Config-r17 are already exempt from the regular SI change notification and valueTag update mechanisms as per 3GPP TS 38.331 version 17.3.0). According to certain embodiments, a mechanism serving to avoid that the above-mentioned changes trigger SI change notifications to be sent (and updates of the valueTag associated with SIB19) could be, for example, one of the following: - One alternative could be to exclude changes of the ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 from the SI changes that trigger SI change notifications and SIB19 valueTag update, and introduce an additional field in SIB19, indicating when the next update of the set of neighbor NTN cells included in the ntn-NeighCellConfigList-r17 and ntn- NeighCellConfigListExt-v1720 IEs will occur, e.g. denoted as nextUpdateOfSetOfNeighbourCells-xx. This new field could be an INTEGER indicating a UTC value or a number of seconds. The field may be optional and present only in TN cells. UEs which are interested in the ntn-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt- v1720 IEs in SIB19 would then have the information they need to know when reacquisition of SIB19 is needed. o The relevant changes of the ntn-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 that should not trigger SI change notifications and SIB19 valueTag update may be changes in the set of of which list items the NTN- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt- v1720 IEs contain, i.e. additions and removals of list items, and changes of the fields within a list item. - Another alternative could be to introduce a new indicator in the Short Message DCI that notifies UEs of SI changes, where the new indication would inform the UE that the SI change concerns an update of the ntn-NeighCellConfigList-r17 IE or the ntn- NeighCellConfigListExt-v1720 IE in SIB19. The execution of the update would not be restricted to a SI modification period border. Upon receiving a SI update notification with this indication, a UE that is interested in the ntn-NeighCellConfigList-r17 and ntn- NeighCellConfigListExt-v1720 IEs in SIB19 would reacquire the updated SIB19, while a UE that is not interested in the ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 would ignore the SI change notification. o More specifically, the indicator in the Short Message DCI could refer specifically to changes in the set of which list items the NTN-NeighCellConfigList-r17 IE and/or ntn- NeighCellConfigListExt-v1720 IE contain (i.e., additions and removals of list items) and changes of the fields within a list item. - Yet another alternative could be to exclude changes of the ntn- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 from the SI changes that trigger SI change notification and SIB19 valueTag update, but not introduce any new parameter in SIB19. It could then be left to UE implementation to ensure that the UE uses valid neighbor NTN cell information, or accept that UEs sometimes will use neighbor NTN cell information which is partly outdated, e.g. a partly outdated set of NTN neighbor cells. o The relevant changes of the ntn-NeighCellConfigList-r17 and ntn-NeighCellConfigListExt-v1720 IEs in SIB19 that should not trigger SI change notifications and SIB19 valueTag update may be changes in the set of of which list items the NTN- NeighCellConfigList-r17 and ntn-NeighCellConfigListExt- v1720 IEs contain, i.e. additions and removals of list items, and changes of the fields within a list item. UE Actions In a particular embodiment (targeting UEs in RRC_CONNECTED state), the essential or relevant parts of SIB19 (in NR) or SIB31 (in LTE) are given to the UE in the measurement object (i.e., the MeasObjectNR IE in NR or the MeasObjectEUTRA IE in LTE) together with a list of PCIs. In an alternative, only an indication, e.g., satellite ID, is added to Measurement Object to assist the UE to identify the required satellite assistance information for the target NTN cell, which the UE obtains by other means such as, for example, reading SI or through dedicated Radio Resource Control (RRC) signaling. In another particular embodiment, the essential or relevant parts of SIB19 (in NR) or SIB31 (in LTE) are provided to UEs in RRC_CONNECTED mode via dedicated RRC signaling. For instance, as part of the RRCReconfiguration message including ReconfigurationWithSync that triggers handover execution and the parameter dedicatedSystemInformationDelivery. In another embodiment, a UE determines one of a plurality of states of the UE with respect to one or more than one of satellite assistance information and adaptively adjusts, updates, or changes one or more operations or aspects related to one or more of the following procedures on TN serving cell or NTN neighbor cell: ^ cell change procedure (e.g., cell reselection, cell selection, RRC connection re-establishment, etc.); ^ measurement procedure (e.g., measurement rate, number, periodicity, duration, total number of carriers/frequencies/cells/satellites to be measured, etc.) and/or ^ channel monitoring or reception procedure (e.g., paging reception, system information reception, etc.). UE may perform one or more of procedures on intra-frequency if no valid NTN assistance information is sent by serving TN cell and received by the UE, but requirements corresponding to the procedures can be relaxed. One example of the embodiment is that UE shall perform one or more of procedures provided valid NTN assistance information sent by serving TN cell is received by the UE only when RSRP/RSRQ received in TN serving cell is higher than a threshold (TH_P1). Another example of the embodiment is that UE shall perform one or more of procedures provided UE doesn’t receive valid NTN assistance information sent by serving TN cell and RSRP/RSRQ received in TN serving cell is lower than a threshold (TH_P2), but requirements corresponding to the procedures can be relaxed. Another example of the embodiment is that UE shall perform one or more of procedures provided the time interval from the time instance when UE receives last NTN assistance information and starts procedures is less than a threshold (T_delta ) and RSRP/RSRQ received in TN serving cell is lower than a threshold (TH_P3), but requirements corresponding to the procedures can be relaxed. In another embodiments, UE operated in serving TN cell does not need to read the SI containing NTN assistance information always. In other words, UE operated in serving TN cell shall read the SI containing NTN assistance information upon fulfilling some conditions such as, for example, a distance between UE position and TN cell boundary is shorter than a threshold (TH_D1) provided TN cell boundary information is known by the UE. FIGURE 3 illustrates a wireless network 100 in accordance with some embodiments. Although the subject matter described herein may be implemented in any appropriate type of system using any suitable components, the embodiments disclosed herein are described in relation to a wireless network, such as the example wireless network illustrated in FIGURE 3. For simplicity, the wireless network 100 of FIGURE 3 only depicts network 106, network nodes 160 and 160b, and wireless devices (WDs) 110. In practice, a wireless network 100 may further include any additional elements suitable to support communication between wireless devices or between a wireless device and another communication device, such as a landline telephone, a service provider, or any other network node or end device. Of the illustrated components, network node 160 and WD 110 are depicted with additional detail. The wireless network 100 may provide communication and other types of services to one or more wireless devices to facilitate the wireless devices’ access to and/or use of the services provided by, or via, the wireless network 100. The wireless network 100 may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. In some embodiments, the wireless network 100 may be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network 100 may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards. Network 106 may comprise one or more backhaul networks, core networks, Internet Protocol (IP) networks, public switched telephone networks (PSTNs), packet data networks, optical networks, wide-area networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices. Network node 160 and WD 110 comprise various components described in more detail below. These components work together in order to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network 100. In different embodiments, the wireless network 100 may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections. FIGURE 4 illustrates an example network node 160, according to certain embodiments. As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network. In FIGURE 4, network node 160 includes processing circuitry 170, device readable medium 180, interface 190, auxiliary equipment 184, power source 186, power circuitry 187, and antenna 162. Network node 160 may be an NTN network node. Although network node 160 illustrated in the example wireless network of FIGURE 4 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node 160 are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium 180 may comprise multiple separate hard drives as well as multiple RAM modules). Similarly, network node 160 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node 160 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB’s. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 180 for the different RATs) and some components may be reused (e.g., the same antenna 162 may be shared by the RATs). Network node 160 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 160, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 160. Processing circuitry 170 is configured to perform any determining, calculating, or similar operations (e.g., certain obtaining operations) described herein as being provided by a network node. These operations performed by processing circuitry 170 may include processing information obtained by processing circuitry 170 by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and/or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination. Processing circuitry 170 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and/or encoded logic operable to provide, either alone or in conjunction with other network node 160 components, such as device readable medium 180, network node 160 functionality. For example, processing circuitry 170 may execute instructions stored in device readable medium 180 or in memory within processing circuitry 170. Such functionality may include providing any of the various wireless features, functions, or benefits discussed herein. In some embodiments, processing circuitry 170 may include a system on a chip (SOC). In some embodiments, processing circuitry 170 may include one or more of radio frequency (RF) transceiver circuitry 172 and baseband processing circuitry 174. In some embodiments, radio frequency (RF) transceiver circuitry 172 and baseband processing circuitry 174 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 172 and baseband processing circuitry 174 may be on the same chip or set of chips, boards, or units In certain embodiments, some or all of the functionality described herein as being provided by a network node, base station, eNB or other such network device may be performed by processing circuitry 170 executing instructions stored on device readable medium 180 or memory within processing circuitry 170. In alternative embodiments, some or all of the functionality may be provided by processing circuitry 170 without executing instructions stored on a separate or discrete device readable medium, such as in a hard-wired manner. In any of those embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 170 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 170 alone or to other components of network node 160, but are enjoyed by network node 160 as a whole, and/or by end users and the wireless network generally. Device readable medium 180 may comprise any form of volatile or non- volatile computer readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk), removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and/or any other volatile or non-volatile, non-transitory device readable and/or computer-executable memory devices that store information, data, and/or instructions that may be used by processing circuitry 170. Device readable medium 180 may store any suitable instructions, data or information, including a computer program, software, an application including one or more of logic, rules, code, tables, etc. and/or other instructions capable of being executed by processing circuitry 170 and, utilized by network node 160. Device readable medium 180 may be used to store any calculations made by processing circuitry 170 and/or any data received via interface 190. In some embodiments, processing circuitry 170 and device readable medium 180 may be considered to be integrated. Interface 190 is used in the wired or wireless communication of signalling and/or data between network node 160, network 106, and/or WDs 110. As illustrated, interface 190 comprises port(s)/terminal(s) 194 to send and receive data, for example to and from network 106 over a wired connection. Interface 190 also includes radio front end circuitry 192 that may be coupled to, or in certain embodiments a part of, antenna 162. Radio front end circuitry 192 comprises filters 198 and amplifiers 196. Radio front end circuitry 192 may be connected to antenna 162 and processing circuitry 170. Radio front end circuitry may be configured to condition signals communicated between antenna 162 and processing circuitry 170. Radio front end circuitry 192 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection. Radio front end circuitry 192 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 198 and/or amplifiers 196. The radio signal may then be transmitted via antenna 162. Similarly, when receiving data, antenna 162 may collect radio signals which are then converted into digital data by radio front end circuitry 192. The digital data may be passed to processing circuitry 170. In other embodiments, the interface may comprise different components and/or different combinations of components. In certain alternative embodiments, network node 160 may not include separate radio front end circuitry 192, instead, processing circuitry 170 may comprise radio front end circuitry and may be connected to antenna 162 without separate radio front end circuitry 192. Similarly, in some embodiments, all or some of RF transceiver circuitry 172 may be considered a part of interface 190. In still other embodiments, interface 190 may include one or more ports or terminals 194, radio front end circuitry 192, and RF transceiver circuitry 172, as part of a radio unit (not shown), and interface 190 may communicate with baseband processing circuitry 174, which is part of a digital unit (not shown). Antenna 162 may include one or more antennas, or antenna arrays, configured to send and/or receive wireless signals. Antenna 162 may be coupled to radio front end circuitry 190 and may be any type of antenna capable of transmitting and receiving data and/or signals wirelessly. In some embodiments, antenna 162 may comprise one or more omni-directional, sector or panel antennas operable to transmit/receive radio signals between, for example, 2 GHz and 66 GHz. An omni-directional antenna may be used to transmit/receive radio signals in any direction, a sector antenna may be used to transmit/receive radio signals from devices within a particular area, and a panel antenna may be a line of sight antenna used to transmit/receive radio signals in a relatively straight line. In some instances, the use of more than one antenna may be referred to as MIMO. In certain embodiments, antenna 162 may be separate from network node 160 and may be connectable to network node 160 through an interface or port. Antenna 162, interface 190, and/or processing circuitry 170 may be configured to perform any receiving operations and/or certain obtaining operations described herein as being performed by a network node. Any information, data and/or signals may be received from a wireless device, another network node and/or any other network equipment. Similarly, antenna 162, interface 190, and/or processing circuitry 170 may be configured to perform any transmitting operations described herein as being performed by a network node. Any information, data and/or signals may be transmitted to a wireless device, another network node and/or any other network equipment. Power circuitry 187 may comprise, or be coupled to, power management circuitry and is configured to supply the components of network node 160 with power for performing the functionality described herein. Power circuitry 187 may receive power from power source 186. Power source 186 and/or power circuitry 187 may be configured to provide power to the various components of network node 160 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). Power source 186 may either be included in, or external to, power circuitry 187 and/or network node 160. For example, network node 160 may be connectable to an external power source (e.g., an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry 187. As a further example, power source 186 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry 187. The battery may provide backup power should the external power source fail. Other types of power sources, such as photovoltaic devices, may also be used.

For example, network node 160 may include user interface equipment to allow input of information into network node 160 and to allow output of information from network node 160. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for network node 160. FIGURE 5 illustrates an example WD 110, according to certain embodiments. As used herein, WD refers to a device capable, configured, arranged and/or operable to communicate wirelessly with network nodes and/or other wireless devices. Unless otherwise noted, the term WD may be used interchangeably herein with UE. Communicating wirelessly may involve transmitting and/or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and/or other types of signals suitable for conveying information through air. In some embodiments, a WD may be configured to transmit and/or receive information without direct human interaction. For instance, a WD may be designed to transmit information to a network on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the network. Examples of a WD include, but are not limited to, a smart phone, a mobile phone, a cell phone, a voice over IP (VoIP) phone, a wireless local loop phone, a desktop computer, a personal digital assistant (PDA), a wireless cameras, a gaming console or device, a music storage device, a playback appliance, a wearable terminal device, a wireless endpoint, a mobile station, a tablet, a laptop, a laptop-embedded equipment (LEE), a laptop-mounted equipment (LME), a smart device, a wireless customer-premise equipment (CPE). a vehicle-mounted wireless terminal device, etc.. A WD may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to- everything (V2X) and may in this case be referred to as a D2D communication device. As yet another specific example, in an Internet of Things (IoT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements, and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD may in this case be a machine-to-machine (M2M) device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the WD may be a UE implementing the 3GPP narrow band internet of things (NB-IoT) standard. Particular examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or home or personal appliances (e.g. refrigerators, televisions, etc.) personal wearables (e.g., watches, fitness trackers, etc.). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting on its operational status or other functions associated with its operation. A WD as described above may represent the endpoint of a wireless connection, in which case the device may be referred to as a wireless terminal. Furthermore, a WD as described above may be mobile, in which case it may also be referred to as a mobile device or a mobile terminal.

FIGURE 7 depicts a wireless network 1000 comprising different devices connected, either directly or indirectly, to the wireless network 1000 through one or more access network nodes, such as gNBs 1060a and 1060b. In particular, the wireless network 1000 includes access network nodes such as gNBs 1060a and 1060b, UE 1010a, hub 1010b, remote devices 1015a and 1015b and server 1009. UE 1010a and hub 1010b may be any of a wide variety of devices capable of communicating wirelessly with gNBs 1060’s. Although hub 1010b is referred to as a hub, it may also be considered a UE (with hub functionality) because it is able to communicate wirelessly with gNB 1060b using a standard protocol, for example a wireless standard such as one provided by 3GPP. In fact, each of the devices illustrated in FIGURE 7 represent a wide variety of different devices that can be used in different scenarios as discussed in more detail below. Any of these devices which are able to communicate wirelessly with a gNB, eNB or any other similar 3GPP access node may be considered a wireless device or UE. Looking now at some of the possibilities, UE 1010a may be any of a variety of different devices that are able to wirelessly communicate with gNB 1060a. Some examples, which are listed in FIGURE 7, include a virtual reality (VR) headset, a sensor, an actuator, a monitoring device, a vehicle, or a remote controller. These examples are not exhaustive and include therein a wide variety of more specific devices, including a wide range of Internet of Things (IoT) devices. For example, in embodiments where UE 1010a is a VR headset, UE 1010a may be a cell phone that is used with a head mount or it may be a standalone or dedicated VR headset. In some embodiments UE 1010a may be an augmented reality (AR) headset. As an AR or VR headset UE 1010a may be used for entertainment (e.g., gaming, videos, etc.), education/business (e.g., remote conferences, virtual lectures, etc.), medical (e.g., remote diagnostic, patient consultation, etc.), or any other use in which virtual or augmented content may be provided to a remote user. In any of these cases UE 1010a may be receiving content via wireless connection 1070a with gNB 1060a. As another example, in embodiments where UE 1010a is a sensor or monitoring device, UE 1010a may be a motion, gravitational, moisture, temperature, biometric, speed, door/window open, smoke, fire, volume, flow, or any other type of device that is able to detect or measure one or more conditions. As a sensor UE 1010a may also be able to capture conditions. For example, UE 1010a may capture images if it comprises a camera or sound if it comprises a microphone. Regardless of the type of sensor, UE 1010a may provide an output via wireless connection 1070a to gNB 1060a. The output may be periodic (e.g., once every 15 minutes if it reports the sensed temperature), random (e.g., to even out the load from reporting from several sensors), in response to a triggering event (e.g., when moisture is detected an alert is sent), in response to a request (e.g., a user initiated request), or a continuous stream (e.g., a live video feed of a patient). As another example, in embodiments where UE 1010a is an actuator, UE 1010a may be a motor, switch, or any other device that may change states in response to receiving an input via wireless connection 1070a. For example, UE 1000a may be a vibrator that creates vibration to provide a user with haptic feedback. As another example UE 1000a may be a small motor that adjusts the control surfaces of a drone in flight or to a robotic arm performing a medical procedure. As another example, UE 1000a may be a switch that remotely turns on another device, such as a light. As another example, in embodiments where UE 1010a is a vehicle, UE 1010a may be a drone, car, plane, ship, train, tractor, robot, or any other type of device comprising one or more sensors and/or actuators that may change its locations whether autonomously or at the direction of a user. In such embodiments where UE 1010a is a remotely controlled vehicle, such as a drone, it may receive instructions on movement, actuating, or sensing from a user via wireless connection 1070a and provide location, sensor or video information back to the user via wireless connection 1070a. In such embodiments where UE 1010a is an autonomous vehicle it may receive alerts and other messages from other vehicles and/or infrastructure sensors via wireless connection 1070a as well provide its own telemetry data to others via wireless connection 1070a. As another example, in embodiments where UE 1010a is a remote control, UE 1010a may be a device dedicated to controlling other devices or a general purpose computer with a program or application that provides control of other devices. UE 1010a may send commands to a remote device via wireless connection 1070a. UE 1010a may also receive feedback, telemetry, or other information from the remote device via wireless connection 1070a. UE 1010a may present this received information to a user who may then issue commands for the remote device. For example, UE 1010a may receive via wireless connection 1070a a video signal from a remote surgical room and then issue commands via wireless connection 1070a to a remote surgical machine that can execute the commands. While only a single UE 1010a is illustrated in FIGURE 7, in practice any number of UEs may be used together with respect to a single use case. For example, a first UE 1010a may be a speed sensor used in a drone which provides the drone’s speed information to a second UE 1010a that is a remote control operating the drone. When the user makes changes from the remote control, a third UE 1010a that is an actuator may adjust a throttle on the drone to increase or decrease the speed. Similarly, in the example above, the first (sensor) and third (actuator) UE 1010a’s may be a single UE that handles communication for both the speed sensor and the actuators or UE QQA 110a may comprise one or more of the above. Similarly, in the example above, a hub, such as hub 1010b, may be used to handle communication between the sensors and actuators and the controller. Hub 1010b may be any of a variety of different devices that provides wireless access to gNB 1060b for one or more remote devices 1015a. Some examples of different types of hubs are listed in Figure QAA and include a controller, router, content source and analytics. Hub 1010b may include memory to store data (e.g., video, audio, images, buffer, sensor data, file share) that is collected from, or is to be provided to, remote device 1015a. Hub 1010b hub may include a processor, operating system, and server functionality. Hub 1010b may include components for wireless communication to enable wireless connection 1071 to remote device 1015a and/or components for a fixed connection to remote device 1015b.

Remote device 1015a may be any of a variety of different devices, for example, remote device 1015a may be a device comprising one or more of sensors, actuators, and/or a screen. Remote device 1015a may alternatively be a VR (or AR) headset, a Machine-2-Machine (M2M) device, an IoT device, an internet of Everything (IoE) device, or any other type of device which is capable of accessing a communication network wirelessly via a hub or a device capable of acting as a hub, which in the present context comprise providing network access to a device which is not able to communicate directly with communication network 1006 via gNB 1060a or 1060b. In some scenarios, remote device 1015a may be able to establish a wireless connection with gNB 1060a or 1060b yet nonetheless still connects via hub QQA 110b. Remote device 1015b may be similar to remote device 1015a in most respects except that it has a wired connection to hub 1010b rather than a wireless connection, such as wireless connection 1071. gNBs 1060a and 1060b may provide various wireless devices such as UE 1010a and hub 1010b with wireless access to network 1006. Network 1006 may connect the various devices illustrated in FIGURE 7 including server 1009 which may host a variety of applications such as live and pre-recorded content, data collection services such as retrieving and compiling data on various ambient conditions detected by a plurality of remote devices 1015a, 1015b or UE 1010a, analytics functionality, social media, functions for controlling or otherwise interacting with remote devices, functions for an alarm and surveillance center, or any other such function done by a server. For example, factory status information may be collected and analyzed by server 1009. As another example, server 1009 may process audio and video data which may have been retrieved from UE 1010a for use in creating maps. As another example, server 1009 may collect and analyze real-time data to assist in controlling vehicle congestion (e.g., controlling traffic lights). As another example, server 1009 may store surveillance video uploaded by remote device 1015b via hub 1010b. As another example, server 1009 may store media content such as video, audio, VR, or AR which it can broadcast, multicast or unicast to remote devices such as UE 1010a or remote device 1015a. As other examples, server 1009 may be used for energy pricing, for remote control of non-time critical electrical load to balance power generation needs, location services, presentation services (such as compiling diagrams etc. from data collected from remote devices), or any other function of collecting, retrieving, storing, analyzing and/or transmitting data.
