[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This Patent Application claims priority to U.S. Patent Application No. 18 / 315,403, filed May 10, 2023, entitled “MEASUREMENT GAP CONFIGURATION FOR A NON-TERRESTRIAL NETWORK CELL” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this Patent Application. TECHNICAL FIELD
[0003] Aspects of the present disclosure relate generally to wireless communication and to techniques and apparatus for measurement gap configuration for non-terrestrial network (NTN) cells. BACKGROUND
[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems can employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3 GPP).
[0005] A wireless network can include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE can communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to
[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols to communicate over the air interfaces. New radio (NR), which can be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and support beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. SUMMARY

[0038] A user equipment (UE) can be configured with a measurement gap that suspends communications in a current serving cell and allows the UE to perform measurements of, for example, intra-frequency cells, inter-frequency cells, or inter-radio access technology (RAT) cells. Regardless of the scenario in which the measurement gap is used and the configuration of the measurement gap itself, the use of the measurement gap impacts the performance of the UE. For example, because the measurement gap interrupts the uplink and downlink communications of the UE, the throughput achieved by the UE is reduced. In a typical mode of operation, the UE is configured with a measurement gap that is used to cause the UE to perform measurements of both non-terrestrial network (NTN) cells and terrestrial network (TN) cells. However, in some scenarios, measurements of NTN cells can not be needed. For example, if the coverage provided by one or more cells of a TN is sufficient to provide acceptable coverage for the UE, then measurements of one or more NTN cells can not be needed (e.g., measurements of only TN cells can be sufficient) and would, in fact, negatively impact the performance of the UE.
[0039] Some aspects described herein provide techniques and apparatus for measurement gap configuration for NTN cells. In some aspects, a UE can receive an NTN measurement gap configuration. In some aspects, the measurement gap configuration can indicate an association of a location configuration with the gap configuration. Here, the UE can selectively perform measurements of the NTN cell according to the gap configuration based at least in part on a match of a location of the UE to a location indicated by the location configuration. Additionally or alternatively, the NTN measurement gap configuration can indicate probability information during a time interval associated with measurements of the NTN cell. Here, the UE 120 can selectively perform measurements of the NTN cell according to the gap configuration and based at least in part on the probability information during the time interval. Generally, the techniques and apparatus described herein enable measurement gaps for NTN cells to be configured based on a location or heading of a UE and TN coverage information.
[0040] In some aspects, the techniques and apparatus described herein implement measurement gap configurations for reducing a number of NTN cell measurements performed by a UE. As a result, interruptions to both uplink and downlink communications of the UE are reduced, thereby improving performance of the UE (e.g., by increasing throughput, by reducing communication latency, etc.).
[0041] Various aspects of the disclosure are more fully described below with reference to the figures. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided as illustrative examples so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be appreciated that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using, in addition to or in place of the apparatus and techniques described herein, other structures, functionality, or structures and functionality disclosed herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of a claim.
[0042] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms, among other examples (collectively referred to as “elements”). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.
[0043] Although aspects can be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G).
[0044] Figure 1 FIG. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 can be or can include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 can include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one UE 120, or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. A network node 110 is generally an entity configured to provide network access to one or more UEs 120. As illustrated, the network node 110 can include one or more network nodes. For example, the network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 can be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs).
[0045] In some examples, the network nodes 110 are or include network nodes that communicate with UEs 120 via radio access links, such as RUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via a front-haul link or a mid-haul link, such as DUs. In some examples, the network nodes 110 are or include network nodes that communicate with other network nodes 110 via a mid-haul link or with a core network via a backhaul link, such as CUs. In some examples, a network node 110, such as an aggregated network node 110 or a disaggregated network node 110, can include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network nodes 110 can include, for example, an NR base station, an LTE base station, a NodeB, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, a RAN node, or combinations thereof. In some examples, the network nodes 110 can interconnect with each other or with one or more other network nodes 110 in the wireless network 100 using any suitable transport network, such as a direct physical connection, an air interface, or a virtual network through various types of front-haul interfaces, mid-haul interfaces, and / or backhaul interfaces.
[0046] In some examples, a network node 110 can provide communication coverage for a particular geographic area. In Third Generation Partnership Project (3GPP), the term "cell" can refer to a coverage area of a network node 110 and / or a subsystem of a network node 110 that serves the coverage area, depending on the context in which the term is used. The network nodes 110 can be macro cells, pico cells, femto cells, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs 120 with service subscriptions. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UEs 120 with service subscriptions. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs 120 that are associated with an access subscription. Figure 1In the illustrated example, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, cells can not necessarily be stationary, and the geographic area of a cell can move according to the location of a mobile network node 110 (e.g., a mobile network node).
[0047] In some aspects, the term “base station” or “network node” can refer to an aggregated base station, disaggregated base station, integrated access and backhaul (IAB) node, relay node, or one or more components thereof. For example, in some aspects, a “base station” or “network node” can refer to a CU, DU, RU, near real-time (near-RT) RAN intelligent controller (RIC), or non-RT RIC, or a combination thereof. In some aspects, the term “base station” or “network node” can refer to one device configured to perform one or more functions, such as those described herein in connection with network node 110. In some aspects, the term “base station” or “network node” can refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which can be located in the same geographic location or different geographic locations) can be configured to perform at least a portion of a function, or to repeat at least a portion of the function, and the term “base station” or “network node” can refer to any one or more of these different devices. In some aspects, the term “base station” or “network node” can refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term “base station” or “network node” can refer to one of a base station function as opposed to another base station function. In this way, a single device can comprise more than one base station.
[0048] Wireless network 100 can include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE 120 or a network node 110). A relay station can be a UE 120 that can relay transmissions for other UEs 120. In Figure 1 In the illustrated example, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d in order to facilitate communication between network node 110a and UE 120d. A network node 110 that relays communications can be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, or the like.
[0049] Wireless network 100 can be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, and / or the like. These different types of network nodes 110 can have different transmit power levels, different coverage areas, and / or different impacts on interference. For example, macro network nodes can have a high transmit power level (e.g., 5 to 40 Watts), while pico network nodes, femto network nodes, and relay network nodes can have relatively lower transmit power levels (e.g., 0.1 to 2 Watts).
[0050] A network controller 130 can couple to or communicate with a set of network nodes 110 and can provide coordination and control for the network nodes 110. The network controller 130 can communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 can also communicate with one another directly, via wireless backhaul communication links, or indirectly via the network controller 130, via wireless or wireline midhaul communication links. In some aspects, the network controller 130 can be a CU or core network equipment, or can include a CU or core network equipment.
[0051] The UEs 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. A UE 120 can include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. A UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device that is configured to communicate via a wireless or wired medium.
[0052] Some UEs 120 can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC or eMTC UEs can include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a network node, another device (e.g., remote device), or some other entity. A
[0053] In general, any number of wireless networks 100 can be deployed in a given geographic area. Each wireless network 100 can support a particular RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, an air interface, or the like. A frequency can be referred to as a carrier, a frequency channel, or the like. In
[0054] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with one another). For example, UE 120 can use peer to peer (P2P) communication, device to device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or netw orking. In such examples, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.
[0055] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various classes, bands, channels, and so on, according to frequency or wavelength. For example, devices of wireless network 100 can communicate using one or more of the operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often (interchangeably) referred to as a “millimeter wave” band in documents and articles, despite the fact that it falls into a larger frequency band identified as Extremely High Frequency (EHF) by the International Telecommunications Union (ITU) (30 GHz - 300 GHz).
[0056] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Moreover, even higher bands are currently under exploration to extend 5G NR operations beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4-a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher bands falls within the EHF band.
[0057] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “Sub-6 GHz” or the like is used herein to generically refer to frequencies that can be below 6 GHz, can be within FR1, or can include mid-band frequencies. Also, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like is used herein to generically refer to frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a, or FR4-1, and / or FR5, or can be within the EHF band. It is contemplated that frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0058] In some aspects, the wireless network 100 can include one or more non-terrestrial network (NTN) deployments, where non-terrestrial wireless communication devices can include network nodes 110. Such network nodes 110 are sometimes referred to as non-terrestrial network nodes 110 (e.g., network nodes 110e in FIG. 1). As used herein, an NTN can refer to a network facilitated by one or more non-terrestrial network nodes 110 and / or one or more other types of non-terrestrial wireless communication devices, such as one or more non-terrestrial relay stations.

[0059] In some aspects, the wireless network 100 can include any number of non-terrestrial wireless communication devices. Non-terrestrial wireless communication devices can include, for example, satellites or high-altitude platforms (HAPs). HAPs can include balloons, airships, airplanes, and / or unmanned aerial vehicles. Non-terrestrial wireless communication devices can be part of an NTN that is separate from the wireless network 100. Alternatively, an NTN can be part of the wireless network 100. In some aspects, satellites can communicate directly and / or indirectly with other entities in the wireless network 100 using satellite communications. Other entities can include UEs (e.g., UEs 120), other satellites (e.g., other network nodes 110) in one or more NTN deployments, other types of network nodes (e.g., stationary or ground-based network nodes), relay stations, and / or one or more components and / or devices included in a core network of the wireless network 100.
[0060] In some aspects, the UE 120 can include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 can receive an NTN measurement gap configuration that indicates an association of a location configuration with a gap configuration, and selectively perform measurements of NTN cells according to the gap configuration based at least in part on a match of a location of the UE 120 to a location indicated by the location configuration. Additionally or alternatively, the communication manager 140 can receive an NTN measurement gap configuration that indicates probability information associated with measurements of NTN cells during a time interval, and selectively perform measurements of NTN cells according to the gap configuration and based at least in part on the probability information during the time interval. Additionally or alternatively, the communication manager 140 can perform one or more other operations described herein.
[0061] In some aspects, network node 110 can include a communication manager 150. As described in more detail elsewhere herein, communication manager 150 can determine an NTN measurement gap configuration for UE 120, the NTN measurement gap configuration indicating an association of a location configuration and a gap configuration, and transmit the NTN measurement gap configuration for reception by UE 120. Additionally, or alternatively, communication manager 150 can determine an NTN measurement gap configuration for UE 120, the NTN measurement gap configuration indicating probability information associated with measurements of NTN cells during a time interval, and transmit the NTN measurement gap configuration for reception by UE 120. Additionally, or alternatively, communication manager 150 can perform one or more other operations described herein.
[0062] As indicated above, Figure 1 are provided as examples. Other examples can differ from what is described with respect to Figure 1 the examples described herein.
[0063] Figure 2 is a diagram illustrating an example 200 of a network node 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. Network node 110 can be equipped with a set of antennas 234a through 234t, such as T antennas (T > 1). UE 120 can be equipped with a set of antennas 252a through 252r, such as R antennas (R > 1). Network node 110 of example 200 includes one or more radio front end components, such as antennas 234 and modem 232. In some examples, network node 110 can include an interface, communication component, or another component that facilitates communication with UE 120 or another network node. Some network nodes 110 can not include radio frequency components that facilitate direct communication with UEs 120, such as one or more CUs or one or more DUs.
[0064] At the network node 110, a transmit processor 220 can receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 can select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 can process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCSs selected for the UE 120 and can provide data symbols for the UE 120. The transmit processor 220 can process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 can generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232t. Each output symbol stream can be provided to a modulator component (shown as MOD) of a modem 232 using a respective modulator component. Each modem 232 can process a respective output symbol stream (e.g., for OFDM) using a respective modulator component to obtain an output sample stream. Each modem 232 can further process the output sample stream (e.g., convert to analog, amplify, filter, and / or upconvert) using a respective modulator component to obtain a downlink signal. The modems 232a through 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t.
[0065] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) can receive the downlink signals from network nodes 110 and / or other network nodes 110 and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 can use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) a received signal to obtain input samples. Each modem 254 can use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from modems 254, can perform MIMO detection on the received symbols if applicable, and can provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, can provide decoded data for the UE 120 to a data sink 260, and can provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. A channel processor can determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some examples, one or more components of UE 120 can be included in a housing 284.
[0066] A network controller 130 can include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 can include, for example, one or more devices in a core network. The network controller 130 can communicate with the network nodes 110 via the communication unit 294.
[0067] One or more antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) can include or be included in one or more antenna panels, one or more antenna groups, a set or sets of antenna elements, and / or one or more antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements (within a single housing or multiple housings), a set of co-planar antenna elements, a set of non-co-planar antenna elements, and / or one or more antenna elements coupled to one or more transmit and / or receive components (such as, for example, one or more components of a modem 254 and / or a modem 264 in FIG. 2). Figure 2
[0068] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, modems 254 of UE 120 can include modulators and demodulators. In some examples, UE 120 includes a transceiver. The transceiver can include any combination of antenna(s) 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (for example, with reference to Figures 4A-11 ) and / or with respect to other processes described herein.
[0069] At network node 110, the uplink signals from UE 120 and / or other UEs can be received by antennas 234, processed by modems 232 (e.g., demodulator components (shown as DEMOD) of modems 232), detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. Network node 110 can include communication unit 244 and can communicate with network controller 130 via communication unit 244. Network node 110 can include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modems 232 of network node 110 can include modulators and demodulators. In some examples, network node 110 includes a transceiver. The transceiver can include any combination of antenna(s) 234, modems 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (for example, with reference to Figures 4A-11 ).
[0070] Controller / processor 240 of network node 110, controller / processor 280 of UE 120, and / or Figure 2Any other components of the network node 110, the UE 120, and / or the network entity 150 can perform one or more techniques associated with measurement gap configuration for NTN cells as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or the controller / processor 290 of the network entity 150 can perform or direct operations of, for example, Figure 2 Any other components of the network node 110, the UE 120, and / or the network entity 150 can perform or direct operations of, for example, Figure 6 the process 600 of FIG. 6, Figure 7 the process 700 of FIG. 7, Figure 8 the process 800 of FIG. 8, Figure 9 the process 900 of FIG. 9, and / or other processes as described herein. The memory 242 and the memory 282 can store data and program codes for the network node 110 and the UE 120, respectively. In some examples, the memory 242 and / or the memory 282 can include a non-transitory computer-readable medium storing one or more instructions for wireless communication (e.g., code and / or program code). The one or more instructions, when executed (e.g., directly, or after compilation, transformation, and / or interpretation by one or more processors of the network node 110 and / or the UE 120) by one or more processors of the network node 110 and / or the UE 120, can cause the one or more processors, the UE 120, and / or the network node 110 to perform or direct operations of, for example, Figure 6 the process 600 of FIG. 6, Figure 7 the process 700 of FIG. 7, Figure 8 the process 800 of FIG. 8, Figure 9 the process 900 of FIG. 9, and / or other processes as described herein. In some examples, executing instructions can include running the instructions, transforming the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.
[0071] In some aspects, the UE 120 includes means for receiving an NTN measurement gap configuration indicating an association of a location configuration with a gap configuration and / or means for selectively performing measurements of an NTN cell according to the gap configuration based at least in part on a match of a location of the UE 120 to a location indicated by the location configuration. Additionally, or alternatively, the UE 120 includes means for receiving an NTN measurement gap configuration indicating probability information associated with measurements of an NTN cell during a time interval and / or means for selectively performing measurements of the NTN cell according to the gap configuration and based at least in part on the probability information during the time interval. The means for the UE 120 to perform operations described herein can include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.
[0072] In some aspects, network node 110 includes means for determining an NTN measurement gap configuration for UE 120, the NTN measurement gap configuration indicating an association of a location configuration with a gap configuration; and / or means for transmitting the NTN measurement gap configuration for reception by UE 120. Additionally, or alternatively, network node 110 includes means for determining an NTN measurement gap configuration for UE 120, the NTN measurement gap configuration indicating probability information associated with measurements of an NTN cell during a time interval; and / or means for transmitting the NTN measurement gap configuration for reception by UE 120. The means for the network node to perform operations described herein can include, among other examples, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.
[0073] Although Figure 2 The blocks in FIG. 14 are illustrated as distinct components only for the sake of clarity, and numerous implementations of the functionality of these blocks can be carried out by a single hardware, software, or combined component or in various combinations of components. For example, the functionality of transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be carried out by controller / processor 280 or under its control.
[0074] As indicated above, Figure 2 are provided as examples. Other examples can differ from what is described with respect to the examples Figure 2 described with respect to the examples
[0075] Deployment of communication systems, such as 5G NR systems, can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, network entity, mobility element of a network, RAN node, core network node, network element, base station, or network equipment can be implemented in an aggregated architecture or a disaggregated architecture. For example, a base station, such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also referred to as a standalone base station or a monolithic base station) or a disaggregated base station. A “network entity” or “network node” can refer to a disaggregated base station or one or more units of a disaggregated base station, such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof.
[0076] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize radio protocol stacks that are physically or logically integrated within a single RAN node (e.g., within a single device or unit). Disaggregated base stations (e.g., disaggregated network nodes) can be configured to utilize protocol stacks that are physically or logically distributed between two or more units, such as one or more CUs, one or more DUs, or one or more RUs. In some examples, a CU can be implemented within a network node, and one or more DUs can be co-located with the CU, or alternatively, can be geographically or virtually spread across one or more other network nodes. The DUs can be implemented to communicate with one or more RUs. Each of the CUs, DUs, and RUs can also be implemented as virtual units, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among other examples.
[0077] Base station type operations or network designs can take into account the aggregated nature of base station functionality. For example, disaggregated base stations can be utilized in IAB networks, open radio access networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or virtualized radio access networks (vRAN, also referred to as cloud radio access networks (C-RAN)) to facilitate scaling of a communication system by separating base station functionality into one or more units that can be deployed individually. Disaggregated base stations can include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which can enable flexibility in network design. The various units of a disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station.
[0078] Figure 3 is a diagram illustrating an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 can include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or indirectly through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 can communicate with one or more DUs 330 via respective fronthaul links, such as over F1 interfaces. Each of the DUs 330 can communicate with one or more RUs 340 via respective front-haul links. Each of the RUs 340 can communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 can be simultaneously served by multiple RUs 340.
[0079] Each of the units (including CU 310, DU 330, RU 340) and near-RT RIC 325, non-RT RIC 315, and SMO framework 305 can include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each of the units, or an associated processor or controller providing instructions to one or more communication interfaces of the respective unit, can be configured to communicate with one or more of the other units via the transmission media. In some examples, each of the units can include a wired interface configured to receive or transmit signals to one or more of the other units through a wired transmission medium and a wireless interface that can include a receiver, a transmitter, or a transceiver (such as a RF transceiver) configured to receive or transmit signals to one or more of the other units through a wireless transmission medium, or both.
[0080] In some aspects, CU 310 can host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among other possibilities. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by CU 310. CU 310 can be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some implementations, CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bi-directionally with the CU-CP units via an interface, such as an El interface. CU 310 can be implemented to communicate with DU 330 for network control and signaling as desired.
[0081] Each DU 330 can correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 can host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers in accordance with a functional split, such as a functional split defined by 3 GPP. In some aspects, the one or more high PHY layers can be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among other examples. In some aspects, the DU 330 can also host one or more low PHY layers, such as implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (which can also be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.
[0082] Each RU 340 can implement lower layer functionality. In some deployments, the RUs 340 controlled by the DUs 330 can correspond to logical nodes that host RF processing functions or low PHY layer functions based on a functional split (e.g., a functional split defined by 3 GPP), such as a lower layer functional split, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, among other examples. In such an architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RUs 340 can be controlled by the corresponding DUs 330. In some scenarios, this configuration can enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.
[0083] The SMO framework 305 can be configured to support RAN deployment and orchestration of non-virtualized network elements and virtualized network elements. For non- virtualized network elements, the SMO framework 305 can be configured to support deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface, such as an Ol interface. For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform, such as an Open Cloud (O-Cloud) platform 390, to perform network element lifecycle management, such as instantiating virtualized network elements, via a cloud computing platform interface, such as an 02 interface. Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, non-RT RICs 315, and near-RT RICs 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of a 4G RAN, such as an Open eNB (O-eNB) 311, via an Ol interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a respective Ol interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support functionality of the SMO framework 305.
[0084] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updates, or policy-based direction of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or in communication with the near-RT RIC 325, such as via an Al interface. The near-RT RIC 325 can be configured to include logical functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface, such as via an E2 interface, that connects one or more CUs 310, one or more DUs 330, or both, and an O-eNB with the near-RT RIC 325.
[0085] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received at the SMO framework 305 or the non-RT RIC 315 from non-network data sources or from network functions. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305, such as via reconfiguration of the 01 interface, or through creation of RAN management policies, such as Al interface policies.
[0086] As indicated above, Figure 3 are provided by way of example. Other examples can differ from those described. Figure 3 without departing from the spirit and scope of the disclosure.
[0087] Non-terrestrial network nodes (e.g., satellites) can use multiple antennas to form multiple beams. In implementation, the multiple beams can operate in different frequency intervals (e.g., different bandwidth parts (BWPs)) in order to, for example, mitigate interference between the multiple beams. In one example configuration, the multiple beams formed by a non-terrestrial network node can be configured as a single cell. In another example configuration, the multiple beams formed by a non-terrestrial network node can be configured as a cell group (e.g., where each cell is associated with at least one of the multiple beams).
[0088] Additionally, in some scenarios, the UE can need to perform measurements that cannot be completed while the UE is tuned to the current serving cell. To accommodate such scenarios, the UE can be configured with measurement gaps. A measurement gap is a period of time during which downlink communications and uplink communications are suspended in the current serving cell to allow the UE to perform measurements of, for example, intra-frequency cells (e.g., cells operating outside of the active BWP), inter-frequency cells, or inter-RAT cells. With respect to inter-frequency cell measurements or inter-RAT cell measurements, the measurement gap should be configured so as to provide the UE with sufficient time to retune the transceiver to the target carrier, perform a set of measurements, and retune the transceiver back to the original carrier. Notably, in such scenarios, a given retuning operation can take approximately 0.5 milliseconds (ms). With respect to intra-frequency cell measurements, in one example, the UE can be configured to utilize analog beamforming (e.g., within frequency range 2 (FR2)), and thus the measurement gap can be configured so as to provide the UE with sufficient time to redirect the beam from the serving cell to the neighboring cell, perform a set of measurements on the neighboring cell, and redirect the beam from the neighboring cell back to the serving cell. As another example with respect to intra-frequency cell measurements, the UE can be configured with an active BWP that does not include an intra-frequency synchronization signal (SS) / physical broadcast channel (PBCH) block, and the measurement gap should be configured so as to provide the UE with sufficient time to retune the transceiver to receive the intra-frequency SS / PBCH block, perform a set of measurements, and retune the transceiver back to the original frequency.
[0089] In some systems, such as NR systems, measurement gap lengths of 1.5 ms, 3 ms, 3.5 ms, 4 ms, 5.5 ms, and 6 ms are defined with repetition periods of 20 ms, 40 ms, 80 ms, and 160 ms. Furthermore, in NR systems, there are generally three different types of measurement gap configurations: (1) measurement gaps for UEs operating in frequency range 1 (FR1) (e.g., gapFR1), (2) measurement gaps for UEs operating in FR2 (e.g., gapFR2), and (3) measurement gaps for all frequencies (e.g., gapUE).
[0090] Regardless of the scenario in which the measurement gap is used and the configuration of the measurement gap itself, the use of the measurement gap impacts the performance of the UE. For example, because the measurement gap interrupts the uplink and downlink communications of the UE, the throughput achieved by the UE is reduced. Thus, more frequent and longer measurement gaps increase the adverse impact on the achievable throughput of the UE.
[0091] In a typical mode of operation, a UE is configured with a measurement gap that is used to cause the UE to perform measurements of both NTN cells and terrestrial network (TN) cells. However, in some scenarios, measurements of NTN cells can not be needed. For example, if coverage provided by one or more cells of a TN is sufficient to provide acceptable coverage for the UE, measurements of one or more NTN cells can not be needed (e.g., measurements of only TN cells can be sufficient) and would, in fact, negatively impact the performance of the UE. For example, measurements of NTN cells in locations with sufficient TN coverage reduce the throughput of the UE due to the frequency of measurements of NTN cells and the relatively long measurement gap length needed for measurements of NTN cells.
[0092] Some aspects described herein provide techniques and apparatuses for measurement gap configuration for NTN cells. In some aspects, a UE can receive an NTN measurement gap configuration. In some aspects, the measurement gap configuration can indicate an association of a location configuration and a gap configuration. Here, the UE can selectively perform measurements of NTN cells according to the gap configuration based at least in part on a match of a location of the UE to a location indicated by the location configuration. Additionally or alternatively, the NTN measurement gap configuration can indicate probability information associated with measurements of NTN cells during a time interval. Here, the UE 120 can selectively perform measurements of NTN cells according to the gap configuration and based at least in part on the probability information during the time interval. Generally, the techniques and apparatuses described herein enable measurement gaps for NTN cells to be configured based on a location or heading of the UE 120 and TN coverage information. In some aspects, the techniques and apparatuses described herein enable measurement gap configurations that reduce the number of NTN cell measurements performed by the UE. As a result, interruptions to both uplink and downlink communications of the UE are reduced, thereby improving the performance of the UE (e.g., by increasing throughput, by reducing communication latency, etc.). Additional details are provided below.
[0093] Figure 4A and Figure 4B is a diagram illustrating an example 400 associated with measurement gap configuration for NTN cells, in accordance with the present disclosure. As shown, the example 400 includes communication between a UE 120 and a network node 110 (e.g., a terrestrial network node 110 or a non-terrestrial network node 110). In some aspects, the UE 120 and the network node 110 can be included in a wireless network, such as the wireless network 100. The UE 120 and the network node 110 can communicate via a wireless access link, which can include uplink and downlink. Figure 4A
[0094] As shown by reference number 402, the network node 110 can determine an NTN measurement gap configuration for the UE 120. The NTN measurement gap configuration is a configuration based at least in part on which the UE 120 selectively performs measurements of NTN cells. In some aspects, the NTN measurement gap configuration associates a location configuration with a gap configuration.
[0095] The location configuration refers to a configuration that indicates a location associated with performance of measurements of one or more NTN cells. In some aspects, the location configuration indicates a location at which the UE 120 is to perform measurements of NTN cells. Alternatively, in some aspects, the location configuration can indicate a location in which the UE 120 is to refrain from performing measurements of NTN cells.
[0096] As one example, the location can be indicated in the location configuration by a latitude range and a longitude range (e.g., a global positioning system (GPS) latitude range and a GPS longitude range) that define a geographic region. In some aspects, the latitude and longitude range can define a geographic region in which the UE 120 is to perform measurements of NTN cells. Alternatively, in some aspects, the latitude and longitude range can define a geographic region in which the UE 120 is to refrain from performing measurements of NTN cells. In such aspects, the UE 120 can be configured to perform measurements of NTN cells when the UE 120 is outside the geographic region.
[0097] As another example, the location can be indicated in the location configuration by a TN cell identification (e.g., a cell identifier of a TN cell), a heading (e.g., a direction), and a heading deviation threshold. In some aspects, the TN cell identification, the heading, and the heading deviation threshold can indicate that the UE 120 is to perform measurements of NTN cells if the UE 120 is attached to the TN cell indicated by the TN cell identification and is moving in the direction indicated by the heading with a deviation that is within the heading deviation threshold. Alternatively, in some aspects, the TN cell identification, the heading, and the heading deviation threshold can indicate that the UE 120 is to refrain from performing measurements of NTN cells if the UE 120 is attached to the TN cell indicated by the TN cell identification and is moving in the direction indicated by the heading with a deviation that is within the heading deviation threshold. In such aspects, the UE 120 can be configured to perform measurements of NTN cells in other cases (e.g., when attached to another TN cell, when attached to the TN cell and moving in another direction, when attached to the TN cell and moving in the direction but with a deviation that is greater than the heading deviation threshold, etc.).
[0098] For example, the location can be indicated by a zone identifier in a location configuration. For example, the network node 110 can transmit (at an earlier time) a zone configuration indicating one or more zones, and the UE 120 can receive the zone configuration indicating one or more zones. Here, the zone configuration can define each zone by a geographic area (e.g., using a set of GPS coordinates) and can associate each zone with a zone identifier. In this example, the location configuration can indicate the zone identifier, which enables the UE 120 to identify the location (e.g., using the zone configuration). In some aspects, one or more zones can be preconfigured on the UE 120, which can reduce overhead associated with the NTN measurement gap configuration. In some aspects, the zone identifier can indicate a zone in which the UE 120 is to perform measurements of NTN cells. Alternatively, in some aspects, the zone identifier can indicate a zone in which the UE 120 is to refrain from performing measurements of NTN cells. In such aspects, the UE 120 can be configured to perform measurements of NTN cells when the UE 120 is outside of the indicated zone.
[0099] In some aspects, the network node 110 can transmit the location configuration, and the UE 120 can receive the location configuration. In some aspects, the location configuration can be transmitted separately from the NTN measurement gap configuration (e.g., before the NTN measurement gap configuration is transmitted by the network node 110). Alternatively, in some aspects, the location configuration can be transmitted with the NTN measurement gap configuration. In some aspects, the location configuration can be transmitted via RRC signaling or another higher layer protocol. In some aspects, the network node 110 can transmit multiple location configurations, and the UE 120 can receive multiple location configurations, each indicating a different location.
[0100] The gap configuration is a configuration indicating one or more characteristics of the measurement gap. For example, the gap configuration can indicate a measurement gap offset (e.g., gapOffset), a measurement gap length (e.g., mgl), a measurement gap repetition period (e.g., mgrp), a measurement gap timing advance (e.g., mgta), and / or the like.
[0101] In some aspects, the network node 110 can transmit the gap configuration, and the UE 120 can receive the gap configuration. In some aspects, the gap configuration can be transmitted separately from the NTN measurement gap configuration (e.g., before the NTN measurement gap configuration is transmitted by the network node 110). Alternatively, in some aspects, the gap configuration can be transmitted with the NTN measurement gap configuration. In some aspects, the location configuration can be transmitted via RRC signaling or another higher layer protocol. In some aspects, the network node 110 can transmit multiple gap configurations, and the UE 120 can receive multiple gap configurations, each indicating a different set of measurement gap characteristics.
[0102] In some aspects, as described above, the NTN measurement gap configuration associates a location configuration with a gap configuration. That is, the NTN measurement gap configuration can indicate a particular set of measurement gap characteristics when the UE 120 is in a particular location.
[0103] In some aspects, the network node 110 can determine the NTN measurement gap configuration based at least in part on information associated with the UE 120 and TN coverage information.
[0104] In some aspects, the information associated with the UE 120 includes route information. The route information is information that represents a route of the UE 120. In some aspects, the route information can be actual route information (e.g., information that indicates an actual route that the UE 120 will follow). Additionally or alternatively, the route information can be predicted route information (e.g., information that indicates a predicted route of the UE 120). In some aspects, the UE 120 can provide the route information to the network node 110. Additionally or alternatively, the network node 110 can determine the route information (e.g., using a route prediction model). Additionally or alternatively, the information associated with the UE 120 can include a current location of the UE 120 (e.g., an actual location of the UE 120 at a current time as indicated by a set of GPS coordinates). Additionally or alternatively, the information associated with the UE 120 can include a predicted location of the UE 120 (e.g., a predicted location of the UE 120 at some future time).
[0105] The TN coverage information is information that indicates a quality or existence of coverage provided by a TN at a given location (e.g., in a given geographic region). In one example, the network node 110 can obtain TN coverage data based at least in part on measurements reported by a number of UEs 120 over time (e.g., different days, different months, different years, etc.), where each of the measurements indicates a location of the UE 120, a state of motion of the UE 120 (e.g., a heading in GPS coordinates), or an association with a particular cell (e.g., a physical cell identifier), among other examples. The network node 110 can maintain information related to such TN coverage data over time, and can generate and maintain a TN coverage model from the TN coverage data.
[0106] In some aspects, the network node 110 can determine an NTN measurement gap configuration based at least in part on information associated with the UE 120 and TN coverage information. As one example, the network node 110 can generate or access TN coverage information in the form of a TN coverage model. Here, the TN coverage model can receive, as input, route information associated with the UE 120 and a current or predicted location of the UE 120, and can provide, as output, an NTN measurement gap configuration (e.g., a location configuration, a gap configuration, an association of a location configuration and a gap configuration, and / or the like). In this way, the network node 110 can utilize TN coverage data and adaptively configure measurement gaps for the UE 120 to perform NTN measurements based at least in part on the route information and the current or predicted location of the UE 120.
[0107] As shown in FIG. 4, the network node 110 can transmit, and the UE 120 can receive, an NTN measurement gap configuration indicating an association of a location configuration and a gap configuration. In some aspects, the network node 110 can transmit the NTN measurement gap configuration and (optionally) the location configuration and / or the gap configuration in a measurement gap configuration information element (IE) (e.g., a MeasGapConfig IE), and the UE 120 can receive the NTN measurement gap configuration and (optionally) the location configuration and / or the gap configuration in a measurement gap configuration information element (IE) (e.g., a MeasGapConfig IE).
[0108] In some aspects, the network node 110 can transmit, and the UE 120 can receive, one or more items of information associated with an NTN cell on which measurements are to be performed during the measurement gap. The information associated with the NTN cell can include, for example, a non-terrestrial network node identifier (e.g., a satellite identifier) associated with the NTN cell, beam information (e.g., a beam identifier) associated with the NTN cell, an indication of a frequency (e.g., a BWP) associated with the measurements, or an item of information associated with providing NTN access to the UE 120.
[0109] As shown in FIG. 4, the UE 120 can selectively perform measurements of the NTN cell according to the gap configuration based at least in part on a match of the location of the UE and a location indicated by the location configuration.
[0110] In some aspects, selectively performing measurements of NTN cells includes performing measurements of NTN cells. As one example, UE 120 can be configured such that when a location of UE 120 matches a location indicated by the location configuration, UE 120 will perform measurements of NTN cells. Here, UE 120 can determine that the location of UE 120 matches the location indicated by the location configuration (e.g., UE 120 is within a latitude range and a longitude range indicated by the location configuration, UE 120 is attached to a TN cell and moving in a heading within a heading deviation threshold indicated by the location configuration, UE 120 is within a zone identified in the location configuration). UE 120 can then perform measurements of NTN cells. In some aspects, UE 120 can perform measurements of NTN cells based at least in part on information associated with NTN cells (e.g., beam information provided by network node 110), as described above.
[0111] In some aspects, selectively performing measurements of NTN cells includes refraining from performing measurements of NTN cells. As one example, UE 120 can be configured such that when a location of UE 120 matches a location indicated by the location configuration, UE 120 will not perform measurements of NTN cells. Here, UE 120 can determine that the location of UE 120 matches the location indicated by the location configuration (e.g., UE 120 is within a latitude range and a longitude range indicated by the location configuration, UE 120 is attached to a TN cell and moving in a heading within a heading deviation threshold indicated by the location configuration, UE 120 is within a zone identified in the location configuration). UE 120 can then refrain from performing measurements of NTN cells.
[0112] In this way, configuration of measurement gaps for NTN cells can be based at least in part on a location or heading of UE 120 and TN coverage information, which enables measurement gap configurations that reduce a number of NTN cell measurements performed by UE 120. As a result, interruptions to both uplink and downlink communications of UE 120 are reduced, thereby improving performance of UE 120 (e.g., by increasing throughput, by reducing communication latency, etc.).
[0113] Figure 4B is a diagram of an example scenario in which the techniques and apparatuses described herein for measurement gap configuration described herein can be applied. In the example shown, ground network node 110a provides coverage in area A, ground network node 110b provides coverage in area B, ground network node 110d provides coverage in area D, and non-ground network node 110e provides coverage in areas A, B, C, and D, notable for the absence of TN coverage in area C. A route of UE 120 is indicated by the dashed line. Figure 4B In the example shown, ground network node 110a provides coverage in area A, ground network node 110b provides coverage in area B, ground network node 110d provides coverage in area D, and non-ground network node 110e provides coverage in areas A, B, C, and D, notable for the absence of TN coverage in area C. A route of UE 120 is indicated by the dashed line.
[0114] In this example, the UE 120 is provided TN coverage during the time period in which the UE 120 moves through the areas A and B and during the time period in which the UE 120 moves through the area D, however the UE 120 does not have TN coverage during the time period in which the UE 120 moves through the area C. Here, the network node 110 (e.g., the terrestrial network node 110a) can determine and transmit to the UE 120 an NTN measurement gap configuration that indicates the UE 120 is to perform measurements of NTN cells (e.g., cells provided by the non-terrestrial network node 110e) only when the UE 120 is in or near the area C. That is, the NTN measurement gap configuration can indicate that the UE 120 is to refrain from performing measurements of NTN cells when the UE 120 is in a location with sufficient TN coverage. Accordingly, the number of NTN cell measurements performed by the UE 120 is reduced, thereby reducing interruptions to uplink and downlink communications of the UE 120 and improving performance of the UE 120 (e.g., by increasing throughput, by reducing communication latency, etc.).
[0115] Notably, in some scenarios, the UE 120 in this example can be a vehicle UE. In another example, the UE 120 can be a UE traveling in a vehicle UE, where an association of the vehicle UE with the passenger UE is known to the network node 110. That is, the techniques and apparatuses described herein can be applicable to a vehicle UE (e.g., for seamless automotive connectivity) or a mobile UE associated with a vehicle UE (e.g., a passenger UE in a vehicle).
[0116] As indicated above, Figure 4A and Figure 4B are provided as examples. Other examples can differ from what is described with respect to Figure 4A and Figure 4B described with respect to
[0117] Figure 5 is a diagram illustrating an example 500 associated with measurement gap configurations of NTN cells, in accordance with the present disclosure. As Figure 5 indicated, the example 500 includes communications between a UE 120 and a network node 110 (e.g., a terrestrial network node 110 or a non-terrestrial network node 110). In some aspects, the UE 120 and the network node 110 can be included in a wireless network, such as the wireless network 100. The UE 120 and the network node 110 can communicate via a wireless access link, which can include uplinks and downlinks.
[0118] As shown by reference number 502, the network node 110 can determine an NTN measurement gap configuration for the UE 120. The NTN measurement gap configuration is a configuration based at least in part on which the UE 120 selectively performs measurements of NTN cells. In some aspects, the NTN measurement gap configuration indicates probability information associated with measurements of NTN cells during a time interval.
[0119] The probability information is information that indicates a probability of performing a measurement of an NTN cell. That is, the probability information can indicate a probability that the UE 120 performs a measurement of an NTN cell at a given location. In some aspects, the probability information can be utilized when, for example, TN coverage at a location is neither particularly strong (e.g., at or above an upper threshold) nor particularly weak (e.g., at or below a lower threshold). In some aspects, the probability information provides a precaution for the UE 120, as the probability information does not completely prevent the UE 120 from performing measurements of NTN cells, but still reduces the number of measurements performed by the UE 120 (e.g., to reduce the risk of loss of connectivity in the event that the UE 120 loses TN coverage).
[0120] In some aspects, the probability information indicates a probability that the UE 120 performs a given NTN measurement. For example, the probability information can indicate a probability of 0.40, which means that there is a 40% chance that the UE 120 applies the indicated gap configuration and performs a measurement of an NTN cell at a given measurement occasion associated with the NTN cell. In some aspects, the UE 120 can perform a given measurement based at least in part on the probability information. For example, the UE 120 can randomly generate a value between 0.0 and 1.0, and can compare the randomly generated value to the probability indicated by the probability information. Here, if the randomly generated value is greater than the indicated probability, the UE 120 can refrain from performing a measurement of the NTN cell. Conversely, if the randomly generated value is less than or equal to the indicated probability, the UE 120 can perform a measurement of the NTN cell. As another example, the probability information can indicate that the UE 120 will perform a subset of configured NTN cell measurements. For example, the probability information can indicate that the UE 120 will perform three (randomly selected) measurements of NTN cells out of the next ten configured measurements of NTN cells.
[0121] In some aspects, the probability information is associated with a time interval. For example, the probability information can indicate that the UE 120 is to apply the probability information in association with determining whether to perform measurements of the NTN within a particular time interval (e.g., after which the UE 120 returns to normal operation). In another example, the probability information can indicate that the UE 120 is to apply the probability information in association with determining whether to perform measurements of the NTN for a next set of measurements (e.g., the next ten configured measurements, after which the UE 120 returns to normal operation). The time interval associated with the probability information can be represented, for example, in terms of a number of slots, a number of frames, an absolute time, and / or the like.
[0122] In some aspects, the network node 110 can determine the NTN measurement gap configuration based at least in part on the TN coverage information. That is, in some aspects, the network node 110 can determine the probability information based at least in part on the TN coverage information.
[0123] As described above, the TN coverage information is information that indicates a quality or presence of coverage provided by a TN at a given location (e.g., in a given geographic region). The network node 110 can maintain information related to such TN coverage data over time and can generate and maintain TN coverage models from the TN coverage data. In some aspects, the network node 110 can determine the NTN measurement gap configuration based at least in part on the TN coverage information. As one example, the network node 110 can generate or access TN coverage information in the form of a TN coverage model. Here, the TN coverage model can indicate an NTN measurement gap configuration (e.g., probability information) for a given location (e.g., a particular geographic region). In this way, the network node 110 can utilize TN coverage data and adaptively configure measurement gaps for UEs 120 to perform NTN measurements.
[0124] As shown in FIG. 4, the network node 110 can transmit the NTN measurement gap configuration indicating the probability information, and the UE 120 can receive the NTN measurement gap configuration indicating the probability information. In some aspects, the network node 110 can transmit the NTN measurement gap configuration, and the UE 120 can receive the NTN measurement gap configuration including the probability information and a gap configuration in a measurement gap configuration information element (IE) (e.g., a MeasGapConfig IE).
[0125] In some aspects, the network node 110 can transmit, and the UE 120 can receive, one or more items of information associated with the NTN cell on which measurements are to be performed during the measurement gap. The information associated with the NTN cell can include, for example, a non-terrestrial network node identifier (e.g., a satellite identifier) associated with the NTN cell, beam information (e.g., a beam identifier) associated with the NTN cell, an indication of a frequency (e.g., a BWP) associated with the measurements, or an item of information associated with providing NTN access to the UE 120.
[0126] As shown by reference number 506, the UE 120 can selectively perform measurements of the NTN cell according to the gap configuration based at least in part on the probability information during the time interval.
[0127] In some aspects, selectively performing measurements of the NTN cell includes performing measurements of the NTN cell. For example, the probability information can indicate a probability of 0.60, which means that there is a 60% chance that the UE 120 applies the indicated gap configuration and performs measurements of the NTN cell at a given measurement occasion associated with the NTN cell. Here, the UE 120 can randomly generate a value between 0.0 and 1.0, and can compare the randomly generated value to the probability indicated by the probability information. In one example, if the randomly generated value is less than or equal to the indicated probability, the UE 120 performs measurements of the NTN cell based at least in part on the indicated gap configuration.
[0128] In some aspects, selectively performing measurements of the NTN cell includes refraining from performing measurements of the NTN cell. For example, the probability information can indicate a probability of 0.60, which means that there is a 60% chance that the UE 120 applies the indicated gap configuration and performs measurements of the NTN cell at a given measurement occasion associated with the NTN cell. Here, the UE 120 can randomly generate a value between 0.0 and 1.0, and can compare the randomly generated value to the probability indicated by the probability information. In one example, if the randomly generated value is greater than the indicated probability, the UE 120 refrains from performing measurements of the NTN cell.
[0129] In this way, the configuration of the measurement gap for the NTN cell can be based at least in part on the probability information and the TN coverage information, which enables a measurement gap configuration that reduces the number of NTN cell measurements performed by the UE 120. As a result, the interruption to both uplink and downlink communications of the UE 120 is reduced, which improves the performance of the UE 120 (e.g., by increasing throughput, by reducing communication latency, etc.).
[0130] As indicated above,Figure 5 are provided as examples. Other examples can differ from what is described with respect to at least one of the described examples. Figure 5
[0131] Figure 6 is a diagram illustrating an example process 600 performed, for example, by a UE, in accordance with aspects of the present disclosure. Example process 600 is an example where the UE (e.g., UE 120) performs operations associated with measurement gap configuration for NTN cells.
[0132] As Figure 6 further shown, in some aspects, process 600 can include selectively performing measurements of the NTN cell according to the gap configuration based at least in part on a match of a location of the UE to a location indicated by the location configuration (block 620). For example, the UE (e.g., using reception component 1002 and / or communication manager 1006, depicted) can selectively perform measurements of the NTN cell according to the gap configuration based at least in part on a match of a location of the UE to a location indicated by the location configuration, as described above. Figure 10

For example, the UE (e.g., using reception component 1002 and / or communication manager 1006, depicted) can selectively perform measurements of the NTN cell according to the gap configuration based at least in part on a match of a location of the UE to a location indicated by the location configuration, as described above.

[0143] In the ninth aspect, selectively performing measurements of NTN cells, either alone or in combination with one or more of the first to eighth aspects, includes suppressing the performance of measurements of NTN cells.

Figure 6 The boxes depicted may be fewer, different, or arranged differently compared to additional boxes. Alternatively, two or more boxes in the process 600 may be executed in parallel.
[0145] Figure 7 This is a diagram illustrating an example process 700 performed by a network node, for example, according to this disclosure. Example process 700 is an example in which a network node (e.g., network node 110) performs operations associated with measurement gap configuration for an NTN cell.
[0146] like Figure 7 As shown, in some aspects, process 700 may include determining an NTN measurement gap configuration for the UE, which indicates the association between a location configuration and a gap configuration (box 710). For example, network nodes (e.g., using...) Figure 11 The depicted communication manager 1106 can determine the NTN measurement gap configuration for the UE, which indicates the association between the location configuration and the gap configuration, as described above.
[0147] like Figure 7 As further shown, in some aspects, process 700 may include sending NTN measurement gap configuration for UE reception (box 720). For example, a network node (e.g., using...)Figure 11 The depicted transmitting component 1104 and / or communication manager 1106 can transmit an NTN measurement gap configuration for reception by a UE, as described above.
[0148] Process 700 can include additional aspects, such as any single aspect or any combination of aspects described below and / or in connection with one or more other processes described elsewhere herein.
[0149] In a first aspect, the NTN measurement gap configuration is determined based at least in part on route information associated with the UE.

[0158] In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, process 700 includes transmitting beam information associated with the NTN cell.
[0159] Although Figure 7 Although Figure 7The depicted ones of the blocks can be preceded by, followed by, or replaced by additional blocks, fewer blocks, different blocks, or differently arranged blocks. Additionally or alternatively, two or more of the blocks of process 700 can be performed in parallel.
[0160] Figure 8 FIG. 8 is a diagram illustrating an example process 800 performed, for example, by a UE, in accordance with the present disclosure. Example process 800 is an example where the UE (e.g., UE 120) performs operations associated with measurement gap configuration for NTN cells.
[0161] As Figure 8 further shown, in some aspects, process 800 can include selectively performing measurements of the NTN cell in accordance with the gap configuration and based at least in part on the probability information during the time interval (block 820). For example, the UE (e.g., using reception component 1002 and / or communication manager 1006, as described above) can selectively perform measurements of the NTN cell in accordance with the gap configuration and based at least in part on the probability information during the time interval, as described above. Figure 10 The depicted reception component 1002 and / or communication manager 1006 can receive an NTN measurement gap configuration indicating probability information associated with measurements of an NTN cell during a time interval, as described above.
[0162] As Figure 8 further shown, in some aspects, process 800 can include selectively performing measurements of the NTN cell in accordance with the gap configuration and based at least in part on the probability information during the time interval (block 820).
