Description

Technical Field

[0001] This application relates in its entirety to wireless communication systems, including systems, apparatus, and methods for measurement capabilities and configurations on shared spectrum terrestrial and non-terrestrial networks. Background Technology

[0002] Wireless mobile communication technologies use various standards and protocols to transmit data between network devices (e.g., base stations, radio heads, etc.) and wireless communication devices. Wireless communication system standards and protocols may include, for example, 3GPP Long Term Evolution (LTE) (e.g., 4G), 3GPP New Radio (NR) (e.g., 5G), and the IEEE 802.11 standard for Wireless Local Area Networks (WLANs) (often referred to as Wi-Fi within industry organizations). ® ).

[0003] As envisioned by 3GPP, different wireless communication system standards and protocols can use various radio access networks (RANs) for communication between RAN network equipment (sometimes collectively referred to as RAN nodes, network nodes, or simply nodes) and wireless communication equipment called UEs. 3GPP RANs can include, for example, Global System for Mobile Communications (GSM), Enhanced Data Rate GSM Evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and / or Next Generation Radio Access Network (NG-RAN).

[0004] Each RAN can use one or more Radio Access Technologies (RATs) for communication between network devices and UEs. For example, GERAN implements the GSM and / or EDGE RAT, UTRAN implements the Universal Mobile Telecommunications System (UMTS) RAT or other 3GPP RATs, E-UTRAN implements the LTE RAT (sometimes simply referred to as LTE), and NG-RAN implements the NR RAT (sometimes referred to herein as the 5G RAT, 5G NR RAT, or simply NR). In some deployments, E-UTRAN may also implement the NR RAT. In some deployments, NG-RAN may also implement the LTE RAT.

[0005] The network equipment used in a RAN can correspond to that RAN. An example of E-UTRAN network equipment is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (also commonly referred to as Evolved Node B, Enhanced Node B, eNodeB, or eNB). An example of NG-RAN network equipment is a Next Generation Node B (sometimes also called gNodeB or gNB).

[0006] The RAN provides communication services to external entities through its connection with the core network (CN). For example, E-UTRAN can utilize the evolved packet core (EPC), while NG-RAN can utilize the 5G core network (5GC). Attached Figure Description

[0015] Various implementations are described with respect to User Equipment (UE), Non-Terrestrial Network (NTN) equipment, and Network Equipment (e.g., Terrestrial Network (TN) equipment). However, references to the UE are provided for illustrative purposes only. The example implementations can be used with any electronic components capable of establishing a connection to a network and configured with hardware, software, and / or firmware for exchanging information and data with the network. Therefore, the UE, NTN equipment, and network equipment described herein are used to represent any suitable electronic equipment.

[0016] Terrestrial cellular networks are typically deployed to separate different portions of the radio frequency (RF) spectrum into different geographical coverage areas, for example, to avoid interference in adjacent coverage areas. Network devices (e.g., base stations or gNodeBs (gNBs)) use a portion of the RF spectrum within a set or configured coverage area, and the network devices are geographically stationary. However, in some geographical areas, UEs may not have coverage from network devices, for example, because the area is far from any network device, or because communication with network devices is blocked by mountains, buildings, or other obstacles.

[0017] NTN equipment, or other network equipment operating above the Earth's surface, can provide communication resources to UEs (e.g., on the ground, in the air, or on water) that have a specific coverage area served by the NTN equipment. UEs lacking proper configuration for coverage from TN equipment can instead communicate with the NTN equipment. In some deployments, the NTN equipment is stationary relative to the ground, while other NTN equipment is mobile relative to the ground. Examples of stationary NTN equipment include satellites in geosynchronous orbit (GSO or GEO). Examples of mobile or NTN equipment include satellites in low Earth orbit (LEO) or medium Earth orbit (MEO), satellites in polar orbit, high altitude platforms (HAPS), or unmanned aerial vehicles (UAVs). UEs can operate on the Earth's surface, but can also operate above that surface or on water, such as on or as part of an aircraft or ship.

[0018] Cellular network operators typically have licenses to operate in specific RF spectrum bands and can deploy networks using both TN and NTN equipment. Therefore, it may be desirable to reuse spectrum already used for TN equipment for NTN equipment, for example, to maximize spectrum utilization. While using specific bandwidths of the RF spectrum between TN equipment to separate coverage areas may be relatively straightforward because TN equipment is stationary, reusing one or more portions of the RF spectrum (e.g., bands, carriers) for NTN equipment can present additional challenges. For example, since at least some NTN equipment can be mobile, and therefore their corresponding coverage areas (cells) are mobile, when the same portion of the RF spectrum is used by both stationary TN (or NTN) cells and mobile NTN cells, the UE can see both NTN and TN cells on such spectrum (observe, measure, or otherwise signal with them). Given the foregoing, technology allows for efficient (e.g., increased or maximized) use of the RF spectrum between stationary (e.g., TN cells) and mobile (e.g., NTN cells).

[0019] Systems, apparatus, and methods for measurement capabilities and configurations on shared (e.g., reused) spectrum terrestrial and non-terrestrial networks are disclosed. In one or more embodiments, in a network having both TN and NTN cells, one or more RF spectrum bands are utilized by both TN and NTN devices (this may also be referred to herein as RF spectrum bands being “shared” or “reused”). The UE then receives control signaling instructing the neighboring cell measurement configuration (e.g., Radio Resource Management (RRM) Measurement Timing Configuration (SMTC) based on Synchronization Signal Blocks (SSBs)) to the UE, indicating that the RF spectrum bands are shared. The UE can then use this configuration to monitor (listen, be configured to receive) and receive reference signals (e.g., SSBs or portions of SSBs) from neighboring network devices (including NTN and TN devices, when such devices are present). Based on the received reference signals (e.g., measurements performed on such reference signals), the UE can then perform mobility operations.

[0020] On the network side, in one or more implementations, the UE provides the network device with UE capability signaling instructing the UE to support RRM measurements based on NTNSSB. In response (e.g., directly or indirectly), the network device then (e.g., directly or indirectly via an NTN device) sends the UE control signaling instructing the configuration of neighboring cell measurements for the UE for the RF spectrum band used by both the TN and NTN devices to serve the UE. With the UE configured, the network can then coordinate coverage under the shared RF spectrum to minimize or eliminate coverage overlap between NTN and TN cells.

[0021] The techniques described herein can allow for the successful (e.g., more efficient) coexistence of mobile NTN and TN equipment in deployment, while improving or maximizing RF spectrum utilization for network operators. In one or more implementations, overlapping coverage areas under shared RF spectrum can be managed.

[0022] Figure 1 An example wireless communication system 100 is illustrated according to one or more aspects described herein. The wireless communication system 100 supports one or more aspects of measurement capabilities and configurations on shared spectrum TN and NTN, as further described herein.

[0023] The wireless communication system 100 includes one or more UEs 102, which may be served by a TN device 106 via a communication link 120 (e.g., having a Radio Resource Control (RRC) connection established with the TN device) or by an NTN device 110 via a communication link 122. Coverage area 116 (e.g., a cell or serving cell) is the service area of ​​the RF spectrum band utilized by the TN device 106 or NTN device 110 serving the UE 102.

[0024] To support UE mobility (e.g., via RRM) as the UE moves relative to the network's coverage area, network devices transmit reference signals that can be monitored (e.g., listened to), received, and measured by the UE. In one or more embodiments, the reference signal is an SSB. Wireless communication system 100 for UE 102 includes a neighboring TN device 104 having a corresponding neighboring cell corresponding to coverage area 114. The neighboring TN device 104 transmits a reference signal 124 (e.g., an SSB) to support RRM (e.g., and other purposes and uses). Wireless communication system 100 for UE 102 also includes an NTN device 108, which is a neighboring NTN device having a corresponding neighboring cell corresponding to coverage area 118. Similar to TN device 104, the NTN device 108, as a neighboring NTN device, transmits a reference signal 126 (e.g., an SSB) to support RRM (e.g., and other purposes and uses).

[0025] In one or more embodiments, UE 102 is a device capable of supporting NTN reference signal measurements (e.g., RRM measurements based on NTN SSB). In some embodiments, when establishing an RRC connection with the network, UE 102 provides UE capability signaling to the network (e.g., via RRC signaling). As part of such UE capability signaling, the UE may provide the network with an indication that the UE supports RRM measurements based on NTN SSB. In some embodiments, the UE capability signaling providing such an indication is part of or associated with a parameter (e.g., parallelSMTC) of an information element associated with the SMTC configuration. According to one or more embodiments, UE 102 provides an indication in the capability signaling (e.g., explicitly or implicitly via a parameter or field value or one or more bits) that is associated with NTN only, TN only, or both NTN and TN.

[0026] In some implementations, control signals (e.g., as part of or within a parallel SMTC) may indicate how many SMTCs UE 102 can support (e.g., via an indication of quantity or range). In one or more implementations, the value or quantity depends on the context in which it is applied. That is, in some implementations, if the indication of capability is for NTN only, the indication of quantity is understood by both UE 102 and the network as indicating the quantity of SMTC-NTN, and if the indication of capability is for both NTN and TN, the indication of quantity is understood by both UE 102 and the network as indicating the total number of SMTC-NTN and SMTC-TN that the UE can support on a single carrier (e.g., a shared RF spectrum band).

[0027] In one or more embodiments, the UE capability signaling providing an indication that the UE supports NTN SSB-based RRM measurements is part of or associated with a parameter of an information element associated with the SMTC configuration, and it also indicates the total number of SMTC-NTN and SMTC-TN that the UE 102 can support on a single carrier (e.g., a shared RF spectrum band). In some embodiments, this UE capability signaling may be a different parameter (e.g., parallelSMTC-NTNandTN) than the parameter indicating that the UE supports NTN SSB-based RRM measurements (e.g., parallelSMTC).

[0028] In one or more embodiments, SMTC-NTN (e.g., for measuring reference signal 124 from TN device 104) and SMTC-TN (e.g., for measuring reference signal 126 from NTN device 108) may conflict in the time domain. In some embodiments, a time conflict may occur when one or more time resources for SMTC-NTN at least partially overlap with one or more time resources for SMTC-TN. In some embodiments, a time conflict occurs when time resources for SMTC-NTN completely overlap with time resources for SMTC-TN, and vice versa. In some embodiments, a time conflict may occur when one or more time resources for SMTC-NTN are within a threshold time (e.g., a certain number of time slots, micro-slots, symbols, frames, subframes, etc.) of one or more time resources for SMTC-TN. In some embodiments, UE 102 may be configured to prioritize SMTC-TN over SMTC-NTN for measurement when a conflict occurs. In other embodiments, UE 102 may be configured to prioritize SMTC-NTN over SMTC-TN for measurement when a conflict occurs. In some further implementations, the network provides UE 102 with an indication to prioritize either SMTC-NTN or SMTC-TN (e.g., via configuration signaling, such as RRC signaling, or via other control signaling, such as MAC CE or DCI). In other implementations, a weighting factor is applied by UE 102 to determine which of SMTC-NTN or SMTC-TN is prioritized during a given time interval. For example, the weighting factor could be 1 / 3, meaning that for every three overlapping SMTCs, UE 102 will use the SMTC for NTN measurements (e.g., the SMTC is SMTC-NTN), but for the remaining two overlapping SMTCs, UE 102 will use the SMTC for TN measurements (e.g., the SMTC is SMTC-TN).

[0029] In one or more embodiments, UE 102 receives control signaling indicating a neighboring cell measurement configuration (e.g., SMTC) for a shared RF spectrum band utilized by both NTN device 108 and TN device 104. In one or more embodiments, UE 102 receives control signaling (e.g., an indication of a neighboring cell measurement configuration for UE 102) in response to an indication of capability sent by UE 102 to the network.

[0030] In one or more implementations, the network deploys NTN and TN cells on the same frequency carrier (the same RF spectrum band), and the network aims to avoid overlap between the coverage areas of NTN equipment cells and TN equipment cells (e.g., at least a portion of the TN equipment cell coverage area). In some implementations, the network configuration of UE 102 may include an indication for a frequency carrier that enables the UE to measure cells of TN equipment, NTN equipment, or both. In some implementations, the same frequency carrier may be configured in two measurement times or configurations for TN equipment and NTN equipment. In some implementations, and as further discussed herein, UE 102 may avoid monitoring multiple SMTCs used for measurement on that frequency carrier (e.g., avoiding monitoring both SMTC-NTN and SMTC-TN).

[0031] In one or more embodiments, the network deploys NTN and TN cells on the same frequency carrier (same RF spectrum band), and the network allows coexistence or overlap of coverage between the NTN equipment cell coverage area and the TN equipment cell coverage area (e.g., at least a portion of the TN equipment cell coverage area). In one or more embodiments, in addition to supporting NTN cell communication, the network utilizes SMTC and / or measurement gaps to configure UE 102 to allow coexistence of NTN and TN cells. In some embodiments, UT 102 monitors both SMTC-NTN and SMTC-TN for mobility purposes.

[0032] In one or more implementations, the network may configure UE 102 to monitor only certain SMTC types used for RRM measurements. In some implementations, in areas where coverage overlaps (e.g., the intersection between coverage area 116 and coverage area 118 or the intersection between coverage area 116 and coverage area 114), UE 102 ignores SMTC-NTN (e.g., SMTCs associated with or for NTN devices such as NTN device 108) and uses SMTC-TN (e.g., SMTCs associated with or for TN devices such as TN device 104).

[0033] In some implementations, the neighboring cell measurement configuration includes an indicator (e.g., a flag) indicating whether each SMTC is for TN, NTN, or both. In some implementations, UE 102 monitors both SMTC-NTN and SMTC-TN for mobility purposes (e.g., for RRM operation).

[0034] In one or more embodiments, the network provides UE 102 with an indication of frequency carrier configuration (e.g., for a shared RF spectrum band), indicating that the carrier is used for both TN and NTN. In some embodiments, neighboring cell measurement configuration is or includes frequency carrier configuration.

[0035] In one or more embodiments, the network provides UE 102 with a configuration for NTN measurement objects and a configuration for TN measurement objects. In some embodiments, the network may configure the same frequency carrier (e.g., share an RF spectrum band) in both measurement object configurations, thereby indicating that the frequency carrier is used for both TN and NTN.

[0036] In one or more embodiments, the network provides UE 102 with a measurement configuration for NTN measurements and a measurement configuration for TN measurements. In some embodiments, the network may configure the same frequency carrier (e.g., share an RF spectrum band) in both measurement configurations, thereby indicating that the frequency carrier is used for both TN and NTN.

[0037] In one or more embodiments, the network may configure UE 102 using SMTCs individually associated with TN and NTN devices. In some embodiments, the network configures UE 102 using SMTCs and provides for each SMTC an indication of whether the SMTC is associated with an NTN device (e.g., SMTC-NTN for NTN measurements), associated with a TN device (e.g., SMTC-TN for TN measurements), or both.

[0038] In one or more embodiments, the network provides UE 102 with a measurement configuration for NTN measurements and a measurement configuration for TN measurements. In some embodiments, the network may configure the same frequency carrier (e.g., share an RF spectrum band) in both measurement configurations, thereby indicating that the frequency carrier is used for both TN and NTN.

[0039] In one or more embodiments, for the same frequency carrier, the network provides UE 102 with a configuration of NTN measurement targets and a separate configuration of NTN measurement targets. The NTN measurement target configuration includes a list of SMTCs for NTN, and the TN measurement target configuration includes a list of SMTCs for TN. In some embodiments, one or more SMTCs for NTN may indicate time resources that conflict with time resources indicated by one or more SMTCs for TN.

[0040] In some implementations, the shared RF spectrum band may be used by TN device 106, NTN device 110, or both. In one or more implementations, control signaling may be RRC signaling configuring RRM at UE 102, and may be transmitted to UE 102 by or via one of TN device 104, TN device 106, NTN device 108, or NTN device 110 or from different network devices not shown. Although two adjacent network devices (TN device 104 and NTN device 108) are shown, consistent with the techniques described herein, any number of additional adjacent network devices may be configured for measurements performed by the network and measured by UE 102 as potential or candidate target cells for RRM operation.

[0041] In one or more embodiments, UE 102 uses neighboring cell measurement configurations received from network devices to receive reference signals from neighboring network devices over a shared RF spectrum, including one or more first reference signals (e.g., reference signal 124) from TN device 104 and one or more second reference signals (e.g., reference signal 126) from NTN device 108. UE 102 may perform mobility operations (e.g., RRM operations) based at least in part on the first or more reference signals received from terrestrial network devices, or the second or more reference signals received from non-terrestrial network devices, or both.

[0042] In one or more embodiments, a network operator operating the wireless communication system 100 can avoid using NTN equipment with the same carrier frequency (e.g., sharing an RF spectrum band) to serve a cell coverage area already served by TN equipment. In one or more embodiments, when NTN equipment 108 approaches the location of TN equipment 106, the network can coordinate NTN equipment 108 to turn off a carrier frequency (e.g., sharing an RF spectrum band). In other embodiments, when the coverage area 118 of NTN equipment 108 approaches the coverage area 116 of TN equipment 106, the network can coordinate NTN equipment 108 to turn off that carrier frequency (e.g., sharing an RF spectrum band).

[0043] In some implementations, network operators operating wireless communication system 100 may wish to avoid NTN device 108 cells covering TN device 104 cells, for example, avoiding coverage overlap between TN and NTN. In such cases, in one or more implementations, if the network configures UE 102 using two SMTC lists applicable to NTN and TN devices on the same frequency carrier, UE 102 monitors only one type of SMTC (e.g., SMTC-NTN or SMTC-TN) used for RRM measurements. In some implementations, UE 102 ignores SMTC-NTN in overlapping coverage areas (e.g., where coverage areas 116 and 118 overlap) (e.g., SMTC-TN is prioritized over SMTC-NTN, such as prioritizing monitoring resources indicated by SMTC-TN over resources indicated by SMTC-NTN). Otherwise, UE 102 monitors SMTC-NTN in coverage area 118 (i.e., NTN-only coverage area) instead of SMTC-TN.

[0044] Figure 2 An example wireless communication system 200 is illustrated according to one or more aspects described herein. The wireless communication system 200 supports one or more aspects of measurement capabilities and configurations on shared spectrum TN and NTN, as further described herein.

[0045] Wireless communication system 200 includes one or more UEs 102, which can be served by TN device 106 via communication link 120 (e.g., having a Radio Resource Control (RRC) connection established with the TN device). Additionally or alternatively, UE 102 can be served by NTN device (such as NTN device 110) via communication link 122. Coverage area 116 (e.g., a cell or serving cell) is the service area of ​​the RF spectrum band utilized by TN device 106 or NTN device 110.

[0046] In one or more embodiments, a network operator operating a wireless communication system 200 can avoid using NTN equipment with the same carrier frequency (e.g., sharing an RF spectrum band) to serve a cell coverage area already served by TN equipment. In such cases, when NTN equipment approaches the location of TN equipment, the network can coordinate with the NTN equipment to shut down that carrier frequency (e.g., sharing an RF spectrum band).

[0047] In one or more embodiments, NTN device 108, as an adjacent NTN device, has a corresponding adjacent cell corresponding to coverage area 118, the center of which is location 206. At a first time, the distance from NTN device 108 to UE 102 is a first distance 210. When NTN device 108 moves a distance 202, the center of coverage area 118 moves a distance 204 and becomes location 208, and the distance from NTN device 108 to UE 102 becomes a second distance 212.

[0048] In one or more embodiments, the network coordinates with NTN device 108 such that once the distance between TN device 106 and NTN device 108 is less than or equal to a threshold distance, NTN device 108 shuts down (e.g., disables, stops transmitting) on ​​a shared frequency carrier (e.g., a shared RF spectrum band). As shown for wireless communication system 200, a first distance 210 meets or exceeds the distance threshold, and NTN device 108 transmits on the shared carrier frequency (e.g., serving a UE in coverage area 118). However, a second distance 212 is less than or equal to the distance threshold, and NTN device 108 no longer transmits on the shared carrier frequency.

[0049] Figure 3 An example wireless communication system 300 is illustrated according to one or more aspects described herein. The wireless communication system 300 supports one or more aspects of measurement capabilities and configurations on shared spectrum TN and NTN, as further described herein.

[0050] The wireless communication system 300 includes one or more UEs 102, which can be served by a TN device 106 via a communication link 120. Alternatively, the UE 102 can be served by an NTN device (such as NTN device 110) via a communication link 122. Coverage area 116 (e.g., a cell or serving cell) is the service area of ​​the RF spectrum band utilized by the TN device 106 or the NTN device 110.

[0051] In one or more embodiments, a network operator operating the wireless communication system 300 can avoid using NTN equipment with the same carrier frequency (e.g., sharing the RF spectrum band) to serve a cell coverage area already served by TN equipment. In such cases, when the NTN equipment approaches the location of the TN equipment, the network can coordinate with the NTN equipment to shut down that carrier frequency (e.g., sharing the RF spectrum band).

[0052] In one or more embodiments, NTN device 108 has corresponding neighboring cells corresponding to coverage area 118, the center of which is location 206. When NTN device 108 moves a track distance of 202, the center of coverage area 118 moves a distance of 204 and becomes location 208. Coverage area 116 of TN device 106 has a radius of 314, and coverage area 118 of NTN device 108 has a radius of 312. Coverage areas 116 and 118 are shown as substantially regular, but may also be of various shapes (e.g., having different radii or distances from the center in different directions), for example due to terrain, buildings, or other variations in the features in which TN device 106 and NTN device 108 are deployed. In one or more embodiments, the coverage area may be the central location of the TN device's location and a simple calculation of the coverage radius.

[0053] In one or more embodiments, the network coordinates with NTN device 108 such that once the distance 310 between coverage area 116 and coverage area 118 is less than or equal to a threshold distance, NTN device 108 shuts down (e.g., disables, stops transmitting) on ​​a shared frequency carrier (e.g., a shared RF spectrum band). As shown for wireless communication system 300, if distance 310 meets or exceeds the threshold distance, NTN device 108 transmits on the shared carrier frequency (e.g., serves the UE in coverage area 118). However, if distance 310 is less than or equal to the threshold distance, NTN device 108 no longer transmits on the shared carrier frequency.

[0054] In some implementations, the threshold distance is equal to the radius 314 of the coverage area 116. In some implementations, the threshold distance may include a margin 316 in addition to the radius 314, and the threshold distance is a threshold distance 318. In still other implementations, the threshold distance is less than the radius 314, and the threshold distance is a threshold distance 320. In other implementations, different threshold distances are used in different directions, or based on whether the network has frequency carriers turned off or on.

[0055] Figure 4 An example method 400 for wireless communication at a UE is illustrated according to one or more aspects described herein. Method 400 supports one or more aspects of measurement capabilities and configurations on shared spectrum TN and NTN, as further described herein. In some cases, the UE may be UE 102 or one of the other UEs described herein. Method 400 may be performed using a processor, main radio component (or transceiver), or other components of the UE.

[0056] At 402, method 400 includes receiving control signaling indicating a neighboring cell measurement configuration for an RF spectrum band used by both terrestrial network equipment and non-terrestrial network equipment to serve the UE.

[0057] At 404, method 400 includes receiving a first or more reference signals of an RF spectrum band from a terrestrial network device and a second or more reference signals of an RF spectrum band from a non-terrestrial network device, according to an indicated neighboring cell measurement configuration.

[0058] At 406, method 400 includes performing mobility operations based at least in part on a first or more reference signals received from a terrestrial network device, or a second or more reference signals received from a non-terrestrial network device, or both.

[0059] In some implementations, control signaling includes information elements indicating that an RF spectrum band is configured for terrestrial measurement, or non-terrestrial measurement, or both.

[0060] In some implementations, the control signaling includes a first information element for terrestrial measurements that identifies the RF spectrum band used for measurements performed by the UE and a second information element for non-terrestrial measurements that identifies the RF spectrum band used for measurements performed by the UE.

[0061] In some implementations, the neighboring cell measurement configuration is an SMTC, which indicates whether the SMTC is used for ground measurement, non-ground measurement, or both.

[0062] In some implementations, the neighboring cell measurement configuration consists of a first SMTC for terrestrial measurements and a second SMTC for non-terrestrial measurements. In some implementations, method 400 further includes: identifying whether the UE is within a terrestrial network coverage area; and prioritizing the first SMTC for terrestrial measurements over the second SMTC for non-terrestrial measurements, at least in part based on the identification that the UE is within a terrestrial network coverage area. In other implementations, method 400 further includes: identifying whether the UE is within a terrestrial network coverage area; and prioritizing the second SMTC for non-terrestrial measurements over the first SMTC for terrestrial measurements, at least in part based on the identification that the UE is outside a terrestrial network coverage area or in a non-terrestrial network coverage area.

[0063] In some implementations, method 400 further includes sending capability signaling instructing the UE to support RRM measurements based on a non-terrestrial network SSB and indicating whether the capability is for non-terrestrial measurements, terrestrial measurements, or both. In some implementations, the capability signaling also indicates the amount of SMTC supported by the UE.

[0064] In some implementations, method 400 further includes sending capability signaling instructing the UE to support RRM measurements based on non-terrestrial network SSBs and instructing the UE to support the total amount of SMTCs for both non-terrestrial and terrestrial measurements.

The following description is for an example wireless communication system 600 operating in conjunction with LTE system standards or specifications provided by 3GPP technical specifications and / or 5G or NR system standards or specifications.

[0084] like Figure 6As shown, the wireless communication system 600 includes UE 602 and UE 604 (but any number of UEs may be used). In this example, UE 602 and UE 604 are exemplified as smartphones (e.g., handheld touchscreen mobile computing devices capable of connecting to one or more cellular networks), but may also include any mobile or non-mobile computing device configured for wireless communication.

[0085] UE 602 and UE 604 can be configured to communicatively couple with RAN 606. In an embodiment, RAN 606 can be NG-RAN, E-UTRAN, etc. UE 602 and UE 604 utilize connections (or channels) with RAN 606 (shown as connection 608 and connection 610, respectively), each connection including a physical communication interface. RAN 606 may include one or more network devices (such as base station 612 and base station 614) implementing connection 608 and connection 610.

[0086] In this example, Connection 608 and Connection 610 are air interfaces that enable this type of communication coupling and can conform to the RAT used by RAN606, such as LTE and / or NR, for example.

[0087] In some implementations, UE 602 and UE 604 may also exchange communication data directly via sidelink interface 616.

This X2 interface may be defined between two or more network devices (e.g., two or more eNBs, etc.) connected to the EPC and / or between two eNBs connected to the EPC. In implementations where the wireless communication system 600 is an NR system (e.g., when CN 624 is a 5GC), interface 622 may be an Xn interface. This Xn interface is defined between two or more network devices (e.g., two or more gNBs, etc.) connected to the 5GC, between base station 612 (e.g., gNB) and eNB connected to the 5GC, and / or between two eNBs connected to the 5GC (e.g., CN 624).

CN 624 may include one or more network elements 626 configured to provide various data and telecommunications services to customers / subscribers (e.g., users of UE 602 and UE 604) connected to CN 624 via RAN 606. Components of CN 624 may be implemented in a single physical device or a separate physical device including components for reading and executing instructions from machine-readable or computer-readable media (e.g., non-transitory machine-readable storage media).

In this implementation, S1 interface 628 may be divided into two parts: an S1 user plane (S1-U) interface, which carries service data between base station 612 or 614 and the serving gateway (S-GW); and an S1-MME interface, which is the signaling interface between base station 612 or 614 and the mobility management entity (MME).

[0092] In this implementation, CN 624 may be a 5GC, and RAN 606 may be connected to CN 624 via NG interface 628. In this implementation, NG interface 628 may be divided into two parts: an NG user plane (NG-U) interface, which carries service data between base station 612 or 614 and the User Plane Function (UPF); and an S1 control plane (NG-C) interface, which is the signaling interface between base station 612 or 614 and the Access and Mobility Management Function (AMF).

Application server 630 can also be configured to support one or more communication services (e.g., VoIP sessions, group communication sessions, etc.) for UE 602 and UE 604 via CN 624. Application server 630 can communicate with CN 624 via IP communication interface 632.
