Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This Patent Application claims priority to U.S. Provisional Patent Application No. 63 / 198,492, filed October 22, 2020, entitled “NEIGHBOR CELL LIST MANAGEMENT IN NON-TERRESTRIAL NETWORKS,” and U.S. Non-Provisional Patent Application No. 17 / 450,797, filed October 13, 2021, entitled “NEIGHBOR CELL LIST MANAGEMENT IN NON-TERRESTRIAL NETWORKS,” which are expressly incorporated by reference herein. BACKGROUND

[0003] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for neighbor cell list management in non-terrestrial networks.

[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 a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE can communicate with a BS via the downlink and uplink. The downlink (or forward link) refers to the communication from the BS to the UE, and the uplink (or reverse link) refers to the communication from the UE to the BS. As will be described in more detail herein, a BS can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, and / or the like.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. NR, which can also 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 (DL), using CP- OFDM and / or SC-FDMA (e.g., also known as discrete Fourier transform spread OFDM (DFT-s- OFDM)) for the uplink (UL), as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there exists a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. SUMMARY

[0029] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may 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 to make this disclosure exhaustive and complete, and to fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or method practiced using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0030] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0031] It should be noted that while the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0032] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. The wireless network 100 may include multiple base stations (BS) 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G node B (NB), access point, transmit / receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0033] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “node B,” “5G NB,” and “cell” are used interchangeably herein.

[0034] In some examples, the cell is not necessarily stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some examples, the BS can use any suitable transport network to interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0035] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0036] In some aspects, wireless network 100 may include one or more non-terrestrial network (NTN) deployments, wherein non-terrestrial wireless communication devices may include UEs (which are interchangeably referred to herein as “non-terrestrial UEs”), BSs (which are interchangeably referred to herein as “non-terrestrial BSs” and “non-terrestrial base stations”), and / or relay stations (which are interchangeably referred to herein as “non-terrestrial relay stations”), as well as other examples. As used herein, “NTN” may refer to a network whose access is facilitated by non-terrestrial UEs, non-terrestrial BSs, and / or non-terrestrial relay stations, as well as other examples.

[0037] Wireless Network 100 may include any number of non-terrestrial wireless communication devices. Non-terrestrial wireless communication devices may include satellites, manned aircraft systems and / or unmanned aircraft system (UAS) platforms, and other examples. Satellites may include low Earth orbit (LEO) satellites, medium Earth orbit (MEO) satellites, geostationary orbit (GEO) satellites and / or highly elliptical orbit (HEO) satellites, and other examples. Manned aircraft systems may include aircraft, helicopters and / or airships, and other examples. UAS platforms may include high-altitude platform stations (HAPS) and may include balloons, airships and / or aircraft, and other examples. Non-terrestrial wireless communication devices may be part of an NTN separate from Wireless Network 100. Alternatively, the NTN may be part of Wireless Network 100. Satellites may use satellite communications to communicate directly and / or indirectly with other entities in Wireless Network 100. Other entities may include UEs (e.g., terrestrial UEs and / or non-terrestrial UEs), other satellites in one or more NTN deployments, other types of BSs (e.g., geostationary and / or terrestrial BSs), relay stations and / or one or more components and / or devices included in the core network of Wireless Network 100, and other examples.

[0038] Wireless network 100 can be a heterogeneous network including different types of BSs such as macro BS, pico BS, femto BS, and relay BS. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0039] Network controller 130 can be coupled to a collection of Base Stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other, for example, directly or indirectly via wireless or wired backhaul. For example, in some aspects, wireless network 100 can be, include, or be included in a wireless backhaul network, sometimes referred to as an Integrated Access and Backhaul (IAB) network. In an IAB network, at least one base station (e.g., base station 110) can be an anchor base station that communicates with the core network via a wired backhaul link (such as a fiber optic connection). An anchor base station can also be referred to as an IAB donor (or IAB-donor), a central entity, and / or a central unit, among other examples. An IAB network can include one or more non-anchor base stations, sometimes referred to as relay base stations, IAB nodes (or IAB-nodes). Non-anchor base stations can communicate directly or (e.g., via one or more non-anchor base stations) indirectly with anchor base stations via one or more backhaul links to form a backhaul path to the core network for carrying backhaul services. The backhaul link can be a wireless link. One or more anchor base stations and / or one or more non-anchor base stations may communicate with one or more UEs (e.g., UE 120) via an access link, which may be a radio link used to carry access services.

[0040] In some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology and / or directional communication (e.g., beamforming and / or precoding, and other examples) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). For example, a radio backhaul link between base stations can use millimeter waves to carry information and / or can be oriented towards a target base station using beamforming and / or precoding, and other examples. Similarly, a radio access link between a UE and a base station can use millimeter waves and / or can be oriented towards a target radio node (e.g., the UE and / or the base station). In this way, inter-link interference can be reduced.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. UEs may be cellular phones (e.g., smartphones), personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, laptops, cordless phones, wireless local loop (WLL) stations, tablets, cameras, gaming devices, netbooks, smartbooks, ultrabooks, medical devices or equipment, biosensors / devices, wearable devices (smartwatches, smart clothing, smart glasses, smart wristbands, smart jewelry (e.g., smart rings, smart bracelets)), entertainment devices (e.g., music or video devices, or satellite radios), vehicle components or sensors, smart meters / sensors, industrial manufacturing equipment, GPS devices, or any other suitable device configured to communicate via wireless or wired media.

[0042] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity, for example, to or from a network (e.g., a wide area network such as the Internet or a cellular network), via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0044] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In some aspects, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0045] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various levels, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2). FR1 can span from 410 MHz to 7.125 GHz, and FR2 can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, FR2 is often referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that the terms "sub-6 GHz," etc., as used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that the terms "millimeter wave," etc., as used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to these modified frequency ranges.

[0046] like Figure 1 As shown, UE 120 may include a first communication manager 140. As described in more detail elsewhere herein, the first communication manager 140 may receive a list of neighboring cells indicating at least one neighboring cell; perform a cell selection procedure or a cell reselection procedure; and hand over to the serving cell if no updated list of neighboring cells is received from the serving cell.

[0047] As described in more detail elsewhere in this document, the first communication manager 140 may determine that the duration of visibility of the serving cell meets a first threshold; determine that the duration of visibility of the new cell meets a second threshold; and perform a cell reselection process to switch from the serving cell to the new cell, at least in part based on the determination that the first threshold and the second threshold are met.

[0048] As described in more detail elsewhere herein, the first communication manager 140 may determine that the cell type of a candidate cell meets the reselection priority condition; and perform a cell reselection process to switch from the serving cell to the candidate cell, at least in part based on the fact that the cell type of the candidate cell meets the reselection priority condition. Additionally or alternatively, the first communication manager 10 may perform one or more other operations described herein.

[0049] like Figure 1 As shown, base station 110 may include a second communication manager 150. As described in more detail elsewhere herein, the second communication manager 150 may perform one or more of the operations described herein.

[0050] As indicated above, Figure 1 This is provided merely as an example. Other examples may be found in relation to [the example provided]. Figure 1 The examples described are different.

[0051] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0052] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and decoding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process (e.g., encode and modulate) the data for that UE based at least in part on the selected MCS(one or more) for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also 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. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Where applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can also process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0053] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can also process the input sample (e.g., for OFDM) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols, and provide the detected symbols, if applicable. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, the Received Signal Strength Indicator (RSSI) parameter, the Reference Signal Received Quality (RSRQ) parameter, and / or the CQI parameter. In some aspects, one or more components of the UE120 may be included in the housing 284.

[0054] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0055] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, among other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.

[0056] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Where applicable, the symbols from the transmitting processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may 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, as referenced. Figures 5 to 12 As described.

[0057] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 for scheduling UE 120 for downlink and / or uplink communications. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceivers. The transceiver may include (or one or more) antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230, and any combination thereof. The transceiver may 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, as referenced. Figures 5 to 12 As described.

[0058] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more technologies associated with neighboring cell list management in the NTN, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 6 Process 600 Figure 7 Process 700 Figure 8 The operation of process 800 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, these one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 6 Process 600 Figure 7 Process 700 Figure 8 The operation of process 800 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, transformation instructions, compilation instructions and / or interpretation instructions, and other examples.

[0059] In some aspects, UE 120 may include: components for receiving a list of neighboring cells indicating at least one neighboring cell; components for performing a cell selection procedure or a cell reselection procedure; and / or components for handing over to the serving cell if an updated list of neighboring cells is not received from the serving cell, and other examples. In some aspects, such components may include combinations of...

[0060] In some aspects, UE 120 may include: components for determining that the duration of visibility of the serving cell meets a first threshold; components for determining that the duration of visibility of the new cell meets a second threshold; and / or components for performing a cell reselection process to switch from the serving cell to the new cell, at least in part based on determining that the first threshold and the second threshold are met, and other examples. In some aspects, such components may include combinations of Figure 2 The UE 120 described includes one or more components such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256 and / or receive processor 258, and other examples.

[0061] In some aspects, UE 120 may include: components for determining that the cell type of a candidate cell satisfies the reselection priority condition; and / or components for performing a cell reselection process to hand over from the serving cell to the candidate cell, at least in part based on determining that the cell type of the candidate cell satisfies the reselection priority condition, and other examples. In some aspects, such components may include combinations of Figure 2 The UE 120 described includes one or more components such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256 and / or receive processor 258, and other examples.

[0062] In some aspects, base station 110 may include components for transmitting a list of neighboring cells. In some aspects, such components may include... Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232 and / or antenna 234, and other examples.

[0063] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to the boxes can be implemented as a single hardware, software, or combined component, or as a combination of various components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0064] As indicated above, Figure 2 This is provided merely as an example. Other examples may be found in relation to [the example provided]. Figure 2 The examples described are different.

[0065] Figure 3 This is a diagram illustrating examples 300 and 310 of an NTN deployment. Examples 300 and / or 310 can be, similar to, include, or be included in a wireless network, such as... Figure 1 The text is a jumbled mix of characters and symbols, making it impossible to translate coherently. It appears to be a collection of Figure 1 The wireless network 100 is described.

[0066] Example 300 illustrates a conceptual depiction of a regenerative satellite deployment. In Example 300, UE 120 is served by satellite 320 via serving link 330. For example, satellite 320 may include one or more functions of BS 110 (e.g., BS 110a), gNB, and / or BS 110 (e.g., radio frequency (RF) filtering, frequency conversion, amplification, demodulation, decoding, handover, routing, decoding, and / or modulation, among others), and other examples. Serving link 330 may include an NR-Uu interface terminating at satellite 320. In some aspects, satellite 320 may be referred to as a non-terrestrial base station, a regenerative repeater, and / or an airborne processing repeater, among other examples. In some aspects, satellite 320 may demodulate uplink RF signals and may modulate baseband signals derived from uplink radio signals to generate downlink RF transmissions. Satellite 320 may transmit downlink RF signals over serving link 330. Satellite 320 may provide cell coverage for UE 120.

[0067] Example 310 illustrates a transparent satellite deployment, which may also be referred to as a bent-tube satellite deployment. In Example 310, UE 120 is served by satellite 340 via serving link 330. Satellite 340 may be referred to as a transparent satellite, a bent-tube satellite, and / or a non-terrestrial relay station, among other examples. Satellite 340 may relay signals received from terrestrial BS 110 via NTN gateway 350. The satellite may repeat the NR-Uu interface via feeder link 360. NTN gateway 350 may use RF link 370 to communicatively connect satellite 340 to BS 110. For example, satellite 340 may receive uplink RF transmissions and may transmit downlink RF transmissions without demodulating the uplink RF transmissions. In some aspects, satellite 340 may convert the uplink RF transmission frequency received on serving link 330 to the downlink RF transmission frequency on feeder link 360, and may amplify and / or filter the uplink RF transmissions. In some aspects, the UE 120 shown in Examples 300 and 310 may be associated with Global Navigation Satellite System (GNSS) capabilities and / or Global Positioning System (GPS) capabilities, as well as other examples, although not all UEs have such capabilities. Satellite 340 can provide and / or facilitate cell coverage for UE 120.

[0068] Service link 330 may include a link between satellite 340 and UE 120, and may include one or more uplinks or downlinks. Feeder link 360 may include a link between satellite 340 and gateway 350, and may include one or more portions of an uplink (e.g., from UE 120 to gateway 350) or a downlink (e.g., from gateway 350 to UE 120).

[0069] Feeder link 360 and service link 330 may each experience Doppler effects due to the movement of satellites 320 and 340 and the potential movement of UE 120. These Doppler effects may be significantly greater than those in terrestrial networks. The Doppler effects on feeder link 360 can be compensated to some extent, but may still be associated with a certain amount of uncompensated frequency error. Furthermore, gateway 350 may be associated with residual frequency error, and / or satellites 320 / 340 may be associated with airborne frequency error. These frequency error sources can cause the received downlink frequency at UE 120 to drift away from the target downlink frequency.

[0070] As indicated above, Figure 3 This is provided as an example. Other examples may be provided in conjunction with [the relevant information]. Figure 3 The examples described are different.

[0071] Figure 4 This is a diagram illustrating example 400 of cell selection in an NTN according to this disclosure. As shown, satellite 405 can serve UE 120. Satellite 405 can provide one or more cells 410. Each cell 410 can include one or more beams. As shown, UE 120 can be served by one of the cells (e.g., "serving cell"). Satellite 415 can provide one or more cells 420. One or more of the cells 420 can be neighboring cells of the serving cell 410. Satellite 405 and / or 415 can include base station 110 and / or relay equipment, and can be, include, be included in, or be similar to Figure 3 Satellite 320 and / or shown Figure 3 Satellite 340 is shown, along with other examples.

[0072] Satellites 405 and / or 415 may use multiple antennas to form multiple beams that create a beam footprint on Earth. In the illustrated example, each cell 410 and / or 420 may include one or more beam footprints 425. One or more different frequency spacings may be associated with each beam to mitigate interference between beams, thereby promoting simultaneous transmission and reception capabilities. In some cases, one or more different beams may be associated with frequency spacings. Frequency spacing may be, or may include, narrowband and / or bandwidth portions, among other examples.

[0073] Each cell 410 and 420 may have one or more associated cell identifiers (IDs) and may have an associated cell selection / reselection parameter set. A “cell selection / reselection parameter set” refers to a set of parameters that can be used for cell selection during the cell selection process and / or for cell reselection during the cell reselection process. The cell selection / reselection parameter set may include one or more parameters. In some cases, the selection / reselection parameter set may be provided to the UE 120 as part of a neighboring cell list. For example, in some cases, each time the UE 120 switches to cell 410 or 420 as the serving cell, the new serving cell provides a neighboring cell list indicating neighboring cells of the serving cell. The indication of neighboring cells may include corresponding cell selection / reselection parameters (for brevity and clarity, these cell selection / reselection parameters may be referred to throughout this document as “cell selection parameters”). Cell selection / reselection information may be provided via system information blocks (SIBs), such as SIB4 and / or SIB5.

[0074] As satellites 405 and / or 415 move, the corresponding cells move on the ground. Satellites may move at speeds of, for example, 7 km / s or faster. Due to the movement of satellites 405 and / or 415, and consequently the movement of the cells, UE 120 may frequently perform cell selection and / or reselection. UE 120 can sense changes in cell coverage even if UE 120 may be stationary. Frequent reselection of NTN cells may result in the frequent discarding of the stored neighbor cell list and the acquisition of an updated neighbor cell list (e.g., SIB), which may lead to unnecessary communication traffic and power consumption at UE 120.

[0075] The techniques and apparatus described herein facilitate the provision of neighboring cells to a UE and allow the UE to perform cell selection or reselection procedures, as well as to switch to a serving cell without discarding a stored list of neighboring cells from the serving cell and without necessarily receiving an updated list of neighboring cells. In some aspects, for example, the UE can store a list and / or cell selection / reselection parameters from the list and reuse these parameters when applicable. For example, in some aspects, non-terrestrial devices such as satellites can periodically return to the same location relative to the ground, and the UE can reuse cell selection / reselection information corresponding to a cell to reselect a cell upon its return. In some aspects, neighboring cells can move along with future cells (cells that may become serving cells in the future). In this case, the list of neighboring cells associated with the moving future cell can be retained and reused. Similarly, the list of potential future cells can be retained and reused. In this way, the aspects enable the UE to suppress the acquisition of an updated list of neighboring cells each time the UE performs a cell selection or reselection procedure. Therefore, the aspects can have a positive impact on the reliability of network communications, including reduced latency and increased throughput, and can reduce UE power consumption.

[0076] Additionally, in some cases, each time UE 120 switches to a new serving cell, UE 120 is constrained to wait at least one second before initiating the new cell reselection process. Due to the speed at which NTN cells move, the one-second constraint may cause reselection failure, as the target cell (which may be referred to as the “new” cell or the “candidate” cell) may no longer be within the geographic area of ​​UE 120 after the one-second period expires.

[0077] The techniques and apparatus described herein can allow cell reselection to occur after a delay in NTN-based cell mobility. In some aspects, for example, in addition to determining that a new cell meets one or more selection and / or reselection criteria, UE 120 can determine whether a set of two thresholds is met. The first threshold may correspond to the visibility duration of the serving cell, and the second threshold may correspond to the visibility duration of the candidate cell (which may be referred to as the “new cell”). “Visibility duration” refers to the remaining amount of time during which a cell will be visible to the UE, allowing the UE to camp on and / or connect to that cell. In this way, the delay between cell selection and / or reselection can be based on cell mobility, resulting in increased cell connectivity and reduced UE power consumption (because the UE may not need to attempt unnecessary and unsuccessful cell reselections).

[0078] In some aspects, the visibility duration, the first threshold, and / or the second threshold can be provided by network devices (e.g., base stations and / or relay stations, and other examples) or selected by the UE. For example, the UE can select the visibility duration, the first threshold, and / or the second threshold from a set of possible values. In some aspects, the visibility duration can be determined by the cell stop time broadcast in the system information of a low Earth orbit (LEO) fixed cell. For LEO mobile cells, the visibility duration can be determined by beam and / or satellite information.

[0079] Additionally, in some cases, cell type priority may be applied. For example, during cell selection, terrestrial network (TN) cells may take precedence over NTN cells, and / or LEO cells may take precedence over GEO cells, among other examples. Due to frequent cell reselections caused by rapidly moving non-terrestrial equipment, priority rules may result in UE 120 ping-pongs between TN and NTN cells and / or between LEO and GEO cells, among other examples.

[0080] The techniques and apparatus described herein can provide reselection priorities for use in situations where frequency priorities are the same, cell reselection is within a frequency range, and / or priority information is unavailable. In some aspects, for reselection, the UE can prioritize the currently serving cell type (e.g., TN cell type, NTN cell type, LEO cell type, GEO cell type, etc.). In some aspects, the network can broadcast a bias parameter corresponding to the priority of the cell type (e.g., to indicate the prioritized cell type). In this way, the aspects can facilitate constraining cell reselection to a specific cell type, thereby avoiding back-and-forth between cell types with significantly different motion characteristics. Therefore, the aspects can have a positive impact on the reliability of network communications, including reduced latency and increased reselection success rate.

[0081] As indicated above, Figure 4 This is provided as an example. Other examples may be provided in conjunction with [the relevant information]. Figure 4 The examples described are different.

[0082] Figure 5 This is a diagram illustrating example 500 of beam and narrowband management according to this disclosure. Figure 5As shown, wireless communication devices 505 and 510 can communicate with UE 515. Wireless communication devices 505 and / or 510 may include non-terrestrial base stations and / or non-terrestrial relay devices, among other examples. Wireless communication devices 505 and / or 510 can provide a cell for supporting wireless communication. Wireless communication devices 505 and / or 510 can provide multiple beams within the cell, and UE 515 can select the beam to switch to when UE 515 moves within the cell (or when the cell moves relative to UE 515). Wireless communication device 505 can provide the serving cell to UE 515.

[0083] As shown by reference numeral 520, wireless communication device 505 can transmit, and UE 515 can receive, a list of neighboring cells indicating at least one neighboring cell. The list of neighboring cells may include multiple cell selection parameters configured to facilitate a cell selection process and / or a cell reselection process. The cell selection parameters may therefore include cell reselection parameters. In some aspects, the multiple cell selection parameters may include a first set of cell selection parameters corresponding to at least one of a first frequency or a first cell identifier; and a second set of cell selection parameters corresponding to at least one of a second frequency or a second cell identifier. The multiple cell selection parameters may be valid for a first geographical region. The first geographical region may correspond to the UE's current location and / or a specified location (e.g., via signaling and / or wireless communication specifications and other examples).

[0084] The neighboring cell list may include one or more cell reselection parameters associated with a potential future serving cell. The one or more cell reselection parameters may correspond to one or more neighboring cells of the potential serving cell. In some aspects, the cell reselection parameters may include at least one of the following: an intra-frequency cell reselection parameter set, or an inter-frequency cell reselection parameter set. UE 515 may perform a location update to indicate the location of UE 515 to the network. The location of UE 515 may correspond to a second geographic area, and UE 515 may obtain multiple updated cell selection parameters valid for the second geographic area.

[0085] In some aspects, UE 515 can detect at least one of a frequency or a cell identifier, and determine a set of cell selection parameters corresponding to at least one of the frequency or cell identifier, at least in part, based on a list of neighboring cells. UE 515 can perform additional cell reselection procedures, at least in part, based on the set of cell selection parameters. For example, wireless communication device 505 may be a satellite returning to the same geographical location. In this case, if UE 515 is stationary, relatively stationary, or returning to that location, UE 515 can reuse the reselection parameters associated with that cell.

[0086] In some aspects, UE 515 can detect cells for which selection / reselection parameters have not been stored. In this case, UE 515 can decide to obtain system information to update it. In some aspects, UE 515 can detect a cell and determine that the neighboring cell list does not include the cell selection parameter set corresponding to that cell. UE 515 can obtain an updated neighboring cell list at least in part based on the determination that the neighboring cell list does not include the cell selection parameter set corresponding to that cell.

[0087] In some aspects, neighboring cells (e.g., provided by wireless communication device 510) can move in addition to the serving cell. A fixed set of intra-frequency and inter-frequency cell reselection parameters can be limited for potential serving cells. A list of future cells that will cover the same area at different times can be provided based on cell location and speed. In some aspects, the network may not indicate the time when a future cell will be in the location of UE 515. UE 515 can calculate the time based on satellite and beam information. In some aspects, the list of future cells may include a list of next cells sharing common system information. In some aspects, a list of neighboring cells and inter-frequency information can be provided. In some aspects, if UE 515 reselects the next future cell, it may not be necessary for UE 515 to obtain the intra-frequency neighboring cell list or the inter-frequency carrier frequency list (e.g., SIB4 and SIB5 in LTE, and SIB3 and SIB4 in NR).

[0088] For example, wireless communication device 505 may transmit, and UE 515 may receive, a list of future cell coverage indicating one or more future cells. As indicated above, the one or more future cells may include one or more cells that will cover one or more locations of UE 515 in one or more future time instances. UE 515 may determine one or more future time instances based at least in part on at least one of the following: UE operating conditions, device information corresponding to a non-terrestrial device (e.g., wireless communication device 510) providing the future cells, or beam information corresponding to one or more beams provided by the non-terrestrial device.

[0089] In some aspects, the future cell coverage list may be valid for an associated validity period. UE 515 may suppress the acquisition of an updated neighboring cell list, at least in part, based on the validity of the future cell coverage list. If UE 515 determines that the validity period has expired, UE 515 may acquire an updated future cell coverage list, at least in part, based on the determination that the validity period has expired. In some aspects, UE 515 may determine that the validity period has expired by detecting the expiration of a validity period expiration timer. In some aspects, the network (e.g., wireless communication device 505) may transmit, and UE 515 may receive, an indication that the validity period has expired.

[0090] In some aspects, UE 515 can determine that its mobility level meets the expiration conditions corresponding to a future cell coverage list. UE 515 can obtain an updated future cell coverage list based at least in part on determining that its mobility level meets the expiration conditions. For example, the mobility level can indicate a mobility state (e.g., whether UE 515 is stationary or moving) and / or a degree of mobility (e.g., whether UE 515 is moving at a speed falling within the “slow”, “medium”, or “fast” range) and other examples.

[0091] As shown by reference numeral 525, UE 515 can determine that the cell type of the candidate cell provided by wireless communication device 510 satisfies the reselection priority condition. In some aspects, the cell type of the candidate cell may include at least one of the following: terrestrial cell type, non-terrestrial cell type, low Earth orbit cell type, medium Earth orbit cell type, or geostationary orbit cell type. UE 515 can determine that a first frequency priority corresponding to the serving cell is the same as a second frequency priority corresponding to the candidate cell, and can determine that the cell type of the candidate cell satisfies the reselection priority condition at least in part based on the determination that the first frequency priority and the second frequency priority are the same. In some aspects, UE 515 can determine that a first frequency corresponding to the serving cell is different from a second frequency corresponding to the candidate cell, and can determine that the cell type of the candidate cell satisfies the reselection priority condition at least in part based on the determination that the first frequency and the second frequency are different.

[0092] In some aspects, UE 515 may determine that a first frequency corresponding to the serving cell is different from a second frequency corresponding to the candidate cell, and may determine that the cell type of the candidate cell satisfies the reselection priority condition based at least in part on the determination that the first frequency is different from the second frequency. In some aspects, UE 515 may determine that the cell type of the candidate cell satisfies the reselection priority condition based at least in part on the determination that the cell type of the candidate cell is the same as the cell type of the serving cell. In some aspects, the network (e.g., wireless communication device 505) may send a broadcast message indicating a deviation parameter corresponding to the reselection priority condition. This deviation parameter may indicate which parameter values ​​will be prioritized.

[0093] As illustrated by reference numeral 530, UE 515 may determine that the duration of serving cell visibility meets a first threshold and the duration of new cell visibility meets a second threshold. For example, in some aspects, UE 515 may determine that the cell provided by wireless communication device 510 meets one or more reselection criteria (e.g., based at least in part on measurements of radio resource management signals associated with the cell). UE 515 may determine that the duration of serving cell visibility meets the first threshold (e.g., greater than the first threshold). UE 515 may determine that the duration of new cell visibility associated with the cell provided by wireless communication device 510 meets the second threshold (e.g., less than the second threshold). In some aspects, UE 515 may determine that the duration of new cell visibility associated with the cell meets the second threshold by at least in part determining that the new cell visibility is greater than the first threshold. UE 515 may perform a cell reselection process to switch from the serving cell to the new cell based at least in part on determining that both the first and second thresholds are met. In some aspects, the second threshold may be greater than or equal to the first threshold.

[0094] In some aspects, UE 515 can determine that a new cell meets cell reselection criteria during a network-defined reselection time interval. The determination of whether cell reselection criteria are met can vary depending on whether the cell reselection process is an inter-frequency cell reselection process, an inter-radio access technology cell reselection process, and / or a rank-based cell reselection process, among other examples.

[0095] As illustrated by reference numeral 535, UE 515 may perform a cell reselection procedure to switch from the serving cell to a new cell. In some aspects, UE 515 may perform a cell selection procedure or a cell reselection procedure to switch to the serving cell without receiving an updated list of neighboring cells from the serving cell.

[0096] In some aspects, the serving cell may include future cells, and the wireless communication device 505 may transmit and the UE 515 may receive a list of future cell coverage. The list of future cell coverage may indicate one or more additional future cells. Therefore, the UE 515 may determine that a cell reselection trigger (which may include a frequency measurement trigger) has occurred. The UE 515 may determine that the additional future cells fail to meet the cell reselection criteria. The UE 515 may perform an additional cell reselection procedure to hand over to a neighboring cell of the serving cell. In some aspects, the UE 515 may determine that it does not include neighboring cell information associated with a neighboring cell of the serving cell. The UE 515 may obtain system information including neighboring cell information based at least in part on the determination that it does not include neighboring cell information.

[0097] In some aspects, UE 515 may fail to detect a cell included in the future cell coverage list, and based on this failure to detect the cell, it may obtain system information including neighboring cell information. The future cell coverage list is a list of cells that can be reselected by UE 515. The allowed cell list may also indicate a list of cells that can be reselected by UE 515. The allowed cell list may also indicate a list of cells that can be selected by UE 515. Cells in the future cell coverage list may be in the neighboring cell list and / or the future cell list, among other examples. In some aspects, cells in the future cell coverage list may not be included in other lists. In some aspects, the future cell coverage list may be provided by the network. In some aspects, UE 515 may suppress the acquisition of a neighboring cell list corresponding to the serving cell, at least in part, based on receiving the future cell coverage list. The serving cell may include future cells, and the future cell coverage list may indicate additional future cells. UE 515 can determine the occurrence of a cell reselection trigger, determine that an additional future cell fails to meet the cell reselection criteria, detect a cell included in the allowed cell list, and based on this, can perform an additional cell reselection process to switch to a cell included in the allowed cell list.

[0098] In some respects, the serving cell may include future cells. A future cell coverage list may indicate additional future cells. UE 515 may determine that a cell reselection trigger has occurred, and may determine that additional future cells have failed to meet cell reselection criteria, or may have failed to detect cells included in the future cell coverage list. Based at least in part on one or more of these determinations, UE 515 may perform an additional cell reselection procedure to hand over to a neighboring cell of the serving cell.

[0099] As indicated above, Figure 5 This is provided as an example. Other examples may be provided in conjunction with [the relevant information]. Figure 5The examples described are different.

[0100] Figure 6 This is a diagram illustrating an example process 600 performed by a UE according to this disclosure. Example process 600 is where the UE (e.g., Figure 5 The example shown is of a UE 515 performing operations associated with neighboring cell list management in a non-terrestrial network.

[0101] like Figure 6 As shown, in some aspects, process 600 may include receiving a list of neighboring cells indicating at least one neighboring cell (box 610). For example, as described above, the UE (e.g., using...) Figure 9 The receiving component 902 depicted can receive a list of neighboring cells indicating at least one neighboring cell.

[0102] like Figure 6 As further illustrated, in some aspects, process 600 may include storing a list of neighboring cells (box 620). For example, as described above, the UE (e.g., using...) Figure 9 The communication manager (904) depicted in the image can store a list of neighboring cells.

[0103] like Figure 6 As further illustrated, in some aspects, process 600 may include performing a cell selection process or a cell reselection process (block 630). For example, as described above, the UE (e.g., using communication manager 904) may perform a cell selection process or a cell reselection process.
