[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 198,490, entitled "BEAM AND NARROWBAND MANAGEMENT," filed October 22, 2020, and U.S. Non-Provisional Patent Application No. 17 / 450,920, entitled "BEAM AND NARROWBAND MANAGEMENT," filed October 14, 2021, which are hereby expressly incorporated by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communications, and more particularly to techniques and apparatus for beam and narrowband management. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). 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 an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the BS via downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0006] The multiple access technologies mentioned above have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards. However, with the continued growth in demand for mobile broadband access, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunications standards that employ these technologies. Summary of the Invention

[0025] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate 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 methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0026] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "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.

[0027] It should be noted that although the aspects herein may be described using terms commonly associated with 5G or NR radio access technology (RAT), 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).

[0028] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc., or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) 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, B-node, gNB, 5G B-node (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.

[0029] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1 In the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c 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,” “B node,” “5G NB,” and “cell” are used interchangeably herein.

[0030] In some examples, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some examples, BSs may 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, using any suitable transport network).

[0031] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS110d can communicate with macro BS110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0032] 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”), etc. As used herein, “NTN” may refer to a network to which access is facilitated by non-terrestrial UEs, non-terrestrial BSs, and / or non-terrestrial relay stations, etc.

[0033] 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, etc. Satellites may include low Earth orbit (LEO) satellites, medium Earth orbit (MEO) satellites, geostationary orbit (GEO) satellites, and / or highly elliptical orbit (HEO) satellites, etc. Manned aircraft systems may include aircraft, helicopters, and / or airships, etc. UAS platforms may include high-altitude platform stations (HAPS) and may include balloons, airships, and / or aircraft, etc. 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 communicate directly and / or indirectly with other entities in Wireless Network 100 using satellite communications. Other entities may include UEs (e.g., terrestrial UEs and / or non-terrestrial UEs), one or more other satellites in one or more NTN deployments, other types of BSs (e.g., stationary or terrestrial BSs), relay stations, and / or one or more components and / or devices included in the core network of Wireless Network 100, etc.

[0034] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] Network controller 130 may be coupled to a set of Base Stations (BSs) and may provide coordination and control over these BSs. Network controller 130 may communicate with each BS via backhaul. These BSs may also communicate with each other directly or indirectly, for example, via wireless or wired backhaul. For example, in some aspects, wireless network 100 may 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) may 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 may also be referred to as an IAB donor (or IAB-donor), central entity, and / or central unit, etc. An IAB network may include one or more non-anchor base stations (sometimes referred to as relay base stations, IAB nodes (or IAB-nodes)). Non-anchor base stations may communicate directly or indirectly with anchor base stations via one or more backhaul links (e.g., via one or more non-anchor base stations) to form backhaul paths to the core network for carrying backhaul traffic. The backhaul link may be a wireless link. Anchored base stations and / or non-anchored base stations may communicate with one or more UEs (e.g., UE 120) via an access link (which may be a radio link for carrying access traffic).

[0036] In some aspects, radio access networks, including IAB networks, can utilize millimeter-wave technology and / or directional communication (e.g., beamforming and / or precoding, etc.) 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 use beamforming and / or precoding, etc., to be directed to a target base station. Similarly, a radio access link between a UE and a base station can use millimeter waves and / or be directed to a target radio node (e.g., the UE and / or the base station). In this way, inter-link interference can be reduced.

[0037] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0038] Some UEs may be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes may provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs may be considered Customer Premises Equipment (CPE). UE 120 may be included within a housing that houses components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0039] 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, frequency 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.

[0040] 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 performed by base station 110.

[0041] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, 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), where the first frequency range (FR1) spans from 410 MHz to 7.125 GHz and the second frequency range (FR2) spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz band." Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that, if used herein, the terms "sub-6 GHz" and the like 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 stated, it should be understood that, if used herein, the terms "millimeter wave" and the like 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 those modified frequency ranges.

[0042] like Figure 1As shown, UE 120 may include a first communication manager 140. As described in more detail elsewhere herein, the first communication manager 140 may, when operating using a first beam corresponding to a cell, select a second beam based at least in part on a set of beam information associated with a second beam corresponding to the cell, wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam; and communicate with a wireless communication device providing the cell using the second beam. Additionally or alternatively, the first communication manager 140 may perform one or more other operations described herein.

[0043] In some aspects, base station 110 may include a second communication manager 150. As described in more detail elsewhere herein, the second communication manager 150 may receive an instruction from a UE operating using a first beam corresponding to a cell to select a second beam corresponding to that cell, wherein the selection is at least partially based on a set of beam information associated with the second beam, and wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam; and to use the second beam to communicate with the UE. Additionally or alternatively, the second communication manager 150 may perform one or more other operations described herein.

[0044] As indicated above, Figure 1 This is provided merely as an example. Other examples may differ from those provided. Figure 1 The example described.

[0045] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to this disclosure. The base station 110 may be equipped with T antennas 234a to 234t, while the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T≥1 and R≥1.

[0046] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit 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) or secondary synchronization signal (SSS)). 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, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator can process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator can further 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 the modulators can be transmitted via T antennas 234a to 234t respectively.

[0047] 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 condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the 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 respects, one or more components of the UE 120 may be included in the housing.

[0048] 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.

[0049] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or be included therein, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. 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 multiple antenna elements within housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include elements coupled to one or more transmission and / or reception components (such as...). Figure 2 One or more antenna elements (one or more components).

[0050] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 may be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulator (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 254) of UE 120 may be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receiver processors 258, transmitter processors 264, and / or TX MIMO processors 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. Figure 5-11 As described.

[0051] 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 where 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 communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (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 a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receiver processors 238, transmitter processors 220, and / or TX MIMO processors 230. 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. Figure 5-11 As described.

[0052] 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 techniques associated with beam and narrowband management, 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 may execute or direct, for example Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. Memory 242 and 282 may store data and program code for use by 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, when executed by one or more processors of base station 110 and / or UE 120 (e.g., direct execution, or execution after compilation, transformation, and / or interpretation), the one or more processors, UE 120, and / or base station 110 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 7The operation of process 700, and / or other processes described herein. In some aspects, the execution instructions may include run instructions, translate instructions, compile instructions, and / or interpret instructions, etc.

[0053] In some aspects, UE 120 may include: means for selecting a second beam, at least in part, based on a set of beam information associated with a second beam corresponding to the cell when operating using a first beam corresponding to the cell, wherein a first narrowband is associated with the first beam and a second narrowband is associated with the second beam; and / or means for communicating with a wireless communication device providing the cell using the second beam, etc. In some aspects, such means may include a combination of Figure 2 One or more components of the described UE 120, 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, etc.

[0054] In some aspects, a wireless communication device (e.g., base station 110) may include: means for receiving an indication from a UE operating using a first beam corresponding to a cell to select a second beam corresponding to that cell, wherein the selection is at least partially based on a set of beam information associated with the second beam, and wherein a first narrowband is associated with the first beam, and a second narrowband is associated with the second beam; and / or means for communicating with the UE using the second beam, etc. In some aspects, such means may include a combination of Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, transmitter processor 220, TXMIMO processor 230, MOD 232 and / or antenna 234, etc.

[0055] although Figure 2 The boxes in the diagram are interpreted as different components, but the functions described above with respect to these boxes can be implemented using a single hardware component, software component, or combination of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.

[0056] As indicated above, Figure 2 This is provided merely as an example. Other examples may differ from those provided. Figure 2 The example described.

[0057] Figure 3These are illustrations of examples 300 and 310 illustrating NTN deployment. Examples 300 and / or 310 can be, similar to, include, or be included in a wireless network, such as... Figure 1 The image shown and the combination Figure 1 The wireless network 100 is described.

[0058] Example 300 illustrates a conceptual description 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 BS110 (e.g., BS110a), gNB, and / or one or more functions of BS110 (e.g., RF filtering, frequency conversion, amplification, demodulation, decoding, handover, routing, decoding, and / or modulation, etc.). 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 onboard processing repeater, etc. In some aspects, satellite 320 may demodulate uplink radio frequency signals and may modulate baseband signals derived from uplink radio signals to generate downlink radio frequency transmissions. Satellite 320 may transmit downlink radio frequency signals over serving link 330. Satellite 320 may provide cellular coverage for UE 120.

[0059] Example 310 illustrates a transparent satellite deployment, which may also be referred to as a bend-tube satellite deployment. In Example 310, UE120 is served by satellite 340 via serving link 330. Satellite 340 may be referred to as a transparent satellite, bend-tube satellite, and / or non-terrestrial relay station, etc. Satellite 340 may relay signals received from ground BS110 via NTN gateway 350. The satellite may repeat the NR-Uu interface via feeder link 360. NTN gateway 350 may communicatively connect satellite 340 and BS110 using RF link 370. 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 frequency of uplink RF transmissions received on serving link 330 to the frequency of downlink RF transmissions on feeder link 360, and may amplify and / or filter the uplink RF transmissions. In some respects, the UE 120 shown in Examples 300 and 310 may be associated with Global Navigation Satellite System (GNSS) capabilities and / or Global Positioning System (GSP) capabilities, but not all UEs have such capabilities. Satellite 340 can provide and / or facilitate cellular coverage of UE 120.

[0060] Service link 330 may include a link between satellite 340 and UE 120, and may include one or more of an uplink or a downlink. 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).

[0061] Due to the movement of satellites 320 and 340, and the potential movement of UE 120, feeder link 360 and service link 330 may each experience Doppler effects. These Doppler effects may be significantly greater than those in terrestrial networks. The Doppler effects on feeder link 360 can be compensated for 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 errors, and / or satellites 320 / 340 may be associated with onboard frequency errors. These sources of frequency errors may cause the downlink frequency received at UE 120 to deviate from the target downlink frequency.

[0062] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0063] Figure 4 This is a diagram illustrating example 400 of beam management in an NTN according to this disclosure. As shown, satellite 405 can serve UE 120. Satellite 405 may include base station 110 and / or relay equipment, and may be, include, be included in, or be similar to Figure 3 Satellite 320 and / or shown Figure 3 The satellite shown is 340, etc.

[0064] As indicated by reference numeral 410 in the attached figure, satellite 405 may use multiple antennas to form multiple beams (shown as "Beam 1", "Beam 2", and "Beam 3"), which occupy an area 415 on Earth. One or more different frequency bands may be associated with each beam to mitigate interference between beams, thereby facilitating synchronous transmission and reception capabilities. In some cases, one or more different beams may be associated with frequency bands. Frequency bands may be, or include, narrowband, such as narrowband as defined in the context of enhanced machine-type communications (eMTC).

[0065] When satellite 405 moves, the beam occupancy area shifts across the ground. The satellite's movement speed can be as high as, for example, 7 km / s or faster. Due to the movement of satellite 405 and thus the cell, multiple tracking areas can be employed within the coverage area. Even if UE 120 is stationary, UE 120 can sense the change in tracking area. Because NTN cells can be very large compared to terrestrial network cells and can cover multiple tracking areas, the cell can provide service to the UE from different tracking areas at the tracking area boundaries. Therefore, an additional physical random access channel format has been developed to support satellite movement, but this may lead to unnecessary preamble ambiguity, paging load, and cell handover. As a result, communication between satellite 405 and UE 120 may be unreliable and may involve increased latency and reduced throughput.

[0066] According to various aspects of the techniques and apparatus described herein, wireless communication devices (which may include non-terrestrial base stations such as satellites, terrestrial base stations, and / or non-terrestrial relay devices, etc.) can provide multiple beams within a cellular cell. The beams can be configured to operate as a single cellular cell, and each beam can operate using a different frequency and / or a different narrowband. In some aspects, the beams can support several narrowbands, each of which can be used for different purposes. In some aspects, the wireless communication device can configure narrowbands for paging and / or Physical Random Access Channel (PRACH) protocols and can provide information to the UE so that the UE can select the appropriate beam and narrowband within the cell. In this way, aspects can facilitate beam and narrowband management to reduce preamble ambiguity, paging load, and cell handover. As a result, aspects may have a positive impact on the reliability of network communications, including reduced latency and increased throughput.

[0067] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0068] Figure 5 This is a diagram illustrating example 500 of beam and narrowband management according to this disclosure. (See diagram for example.) Figure 5 As shown, wireless communication device 505 and UE 510 can communicate with each other. Wireless communication device 505 may include non-terrestrial base stations and / or non-terrestrial relay devices, etc. Wireless communication device 505 can provide a cellular cell for supporting wireless communication. Wireless communication device 505 can provide multiple beams within the cellular cell, and when UE 510 moves within the cellular cell (or the cellular cell moves relative to UE 510), UE 510 can select which beam to switch to.

[0069] As indicated by reference numeral 515, the wireless communication device 505 can transmit and the UE 510 can receive beam and / or narrowband information. For example, the UE 510 can operate using a first beam corresponding to the cell, and the wireless communication device 505 can transmit a set of beam information associated with a second beam via the first beam. In some aspects, a first narrowband can be associated with the first beam and a second narrowband can be associated with the second beam. In some aspects, the UE 510 can store the set of beam information in its memory and can access the set of beam information at a later time to facilitate the selection of a beam and / or narrowband. In some aspects, the UE 510 can operate using the first beam to receive first downlink communication via the first narrowband, and the UE 510 can communicate with the wireless communication device 505 using a second beam to transmit uplink communication via a second narrowband that does not match the first narrowband.

[0070] The beam information set may include any number of information of different types. For example, in some aspects, the beam information set may include an indication of a beam identifier (ID) corresponding to the second beam. The beam ID may be carried in at least one of the following: PSS, SSS, Master Information Block (MIB), or System Information Block (SIB).

[0071] In some aspects, for example, the MIB may indicate an index corresponding to at least one of the following: a paging narrowband list among multiple paging narrowband lists, or a PRACH narrowband among multiple PRACH narrowbands. In some aspects, the wireless communication device 505 may transmit, and the UE 510 may receive, a first MIB associated with a first beam and a second MIB associated with a second beam. The first MIB may be carried using a first frequency, while the second MIB may be carried using a second frequency. In some aspects, the second frequency may match the first frequency. The second frequency may be matched to the first frequency by being the same frequency, being a multiple of the first frequency, being within a threshold range of the first frequency, and / or according to a standard or specification. In this way, the UE 510 may be able to identify the first beam and the second beam as part of the same cell and / or may be able to receive both MIBs without changing the frequency.

[0072] In some aspects, the wireless communication device 505 can transmit, and the UE 510 can receive, a first SIB associated with a first beam and a second SIB associated with a second beam. The first SIB can be carried using a first narrowband and the second SIB can be carried using a second narrowband matched with the first narrowband. In some aspects, the wireless communication device 505 can transmit, and the UE 510 can receive, a first paging message associated with the first beam and a second paging message associated with the second beam. The first paging message can be carried using the first narrowband and the second paging message can be carried using the second narrowband. The second narrowband may not match the first narrowband. In this way, the UE 510 may be able to identify that the first beam and the second beam are different beams based on the narrowband.

[0073] In some aspects, UE 510 can transmit and UE 510 can receive uplink random access channel (RACH) messages associated with a first beam, and UE 510 can receive response RACH messages associated with a second beam. The uplink RACH messages can be carried using a first narrowband, and the response RACH messages can be carried using a second narrowband that is mismatched with the first narrowband. In some aspects, UE 505 can transmit and UE 510 can receive downlink RACH messages associated with a first beam, and UE 510 can transmit and UE 505 can receive response RACH messages associated with a second beam. The downlink RACH messages can be carried using a first narrowband, and the response RACH messages can be carried using a second narrowband that is mismatched with the first narrowband.

[0074] In some aspects, the first beam may correspond to a first beam configuration and the second beam may correspond to a second beam configuration. The third beam may correspond to the first configuration. The first configuration may include at least one of the following: an indication of a first physical cell identifier (PCID), an indication of transmitting a first beam ID in a first MIB, or an indication of transmitting at least one of the following using a first frequency: a first PSS, a first SSS, or a first MIB. The second configuration includes at least one of the following: an indication of a first PCID, an indication of transmitting a second beam ID in a second MIB, or an indication of transmitting at least one of the following using a second frequency: a second PSS, a second SSS, or a first MIB.

[0075] In some aspects, the first configuration may include at least one of the following: an indication of a first PCID, an indication to transmit a first paging message using a first narrowband, an indication to transmit a first paging narrowband list, an indication to transmit a first RACH message using a first narrowband, or an indication to transmit at least one of the following using a first frequency: a first PSS, a first SSS, or a first MIB. The second configuration may include at least one of the following: an indication of a second PCID, an indication to transmit a second paging message using a second narrowband, an indication to transmit a second paging narrowband list, an indication to transmit a second RACH message using a second narrowband, or an indication to transmit at least one of the following using a first frequency: a second PSS, a second SSS, or a second MIB.

[0076] In some aspects, UE 510 may identify the second beam at least in part based on the frequency associated with the second beam and the PCID associated with the second beam. In some aspects, wireless communication device 505 may transmit, and UE 510 may receive, a MIB associated with the second beam and may identify the second beam at least in part based on the MIB. For example, the MIB may include a PCID and / or beam ID identifying the second beam.

[0077] As shown by reference numeral 520 in the accompanying drawings, UE 510 may select a beam and / or a narrowband. For example, UE 510 may select a second beam corresponding to a cell when operating with a first beam corresponding to that cell. UE 510 may select the second beam and / or the associated narrowband based at least in part on a set of beam information associated with the second beam. In some aspects, UE 510 may select the second narrowband based at least in part on determining a match between a first PCID associated with the first narrowband and a second PCID associated with the second narrowband.

[0078] In some respects, the first PCID associated with the first narrowband may not match the second PCID associated with the second narrowband. In those cases, UE 510 may select the second beam at least in part based on receiving the first MIB associated with the first beam. The first MIB may indicate a first System Information Block 1 Bandwidth Reduction (SIB1-BR) schedule. UE 510 may receive the second MIB associated with the second beam. The second MIB may indicate a second SIB1-BR schedule, and UE 510 may determine that the first SIB1-BR schedule matches the second SIB1-BR schedule. UE 510 may select the second beam at least in part based on determining that the first SIB1-BR schedule matches the second SIB1-BR schedule.

[0079] As indicated by reference numeral 525, wireless communication device 505 and UE 510 may communicate using selected beams and / or narrowbands. For example, in some aspects, operating with a first beam may include transmitting a first uplink communication using a first narrowband, and communicating with the wireless communication device using a second beam may include transmitting a second uplink communication using a second narrowband that does not match the first narrowband. In some aspects, operating with a first beam may include receiving a first downlink communication using a first narrowband, and communicating with the base station using a second beam may include receiving a second downlink communication using a second narrowband that does not match the first narrowband.

[0080] In some aspects, UE 510 may suppress reception of the SIB associated with the second beam. In some aspects, UE 510 may receive paging messages at least in part based on the last connected cell and the last connected beam. The first beam may correspond to a first non-terrestrial device and the second beam may correspond to a second non-terrestrial device. In some aspects, for example, UE 510 may receive the MIB associated with the second beam. UE 510 may determine, at least in part, that the second beam is associated with an NTN based on the MIB. In some aspects, the MIB includes a Physical Channel Hybrid Automatic Repeat Request (HARQ) Indicator Channel (PHICH) configuration field. The PHICH configuration field may indicate the beam identifier associated with the second beam.

[0081] In some aspects, a first beam ID corresponding to a first beam may be associated with a first paging narrowband set, and a second beam ID corresponding to a second beam may be associated with a second paging narrowband set. The wireless communication device 505 may transmit, and the UE 510 may receive, an indication of the first paging narrowband set. The UE 510 may receive an indication of a paging narrowband offset associated with the second beam and may determine the second paging narrowband set at least in part based on the indications of the first paging narrowband set and the paging narrowband offset.

[0082] In some aspects, the first beam ID may correspond to a first beam and may be associated with a first PRACH narrowband set. The second beam ID may correspond to a second beam and may be associated with a second PRACH narrowband set. In some aspects, the wireless communication device 505 may transmit, and the UE 510 may receive, a mapping of multiple beam identifiers to at least one of the following: multiple paging narrowbands, or multiple PRACH narrowbands. This mapping may be carried using at least one of the following: SIB or Radio Resource Control (RRC) messages.

[0083] In some aspects, using a second beam to communicate with a wireless communication device can be based at least in part on determining that per-beam access prohibition mechanism conditions are met. In some cases, the access prohibition mechanism conditions can be configured to prohibit access beams at least in part based on conditions such as beam ID, paging narrowband index, and / or PRACH narrowband index. For example, in some aspects, wireless communication device 505 can transmit and UE 510 can receive at least one SIB before initiating a PRACH procedure, wherein the at least one SIB indicates a per-beam prohibition bit mapping. The at least one SIB may include, for example, SIB 14 and / or SIB 25. The per-beam prohibition bit mapping can be configured based on beam ID, paging index, and / or PRACH narrowband index. The bit mapping can be based at least in part on at least one of the following: beam ID, paging narrowband index, or PRACH narrowband index. In some aspects, the per-beam access prohibition mechanism conditions can be based at least in part on coverage enhancement level. For example, the first beam of a cell can allow access only at coverage enhancement level 1, while the second beam can allow access only at coverage enhancement level 2.
