[0003] open field

[0004] Various aspects of this disclosure generally relate to wireless communication, and to techniques and apparatus for displaying radio access technology (RAT) status indications based on bandwidth metrics.

[0005] Related technical descriptions

[0006] 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).

[0007] A wireless network may include several base stations (BSs) capable of supporting communication for several user equipments (UEs). UEs may communicate with base stations via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the base station to the UE, while an "uplink" (or "backlink") refers to the communication link from the UE to the base station. As will be described in more detail herein, base stations may be referred to as B-nodes, gNBs, access points (APs), radio headends, transmit / receive points (TRPs), new radio (NR) base stations, 5G B-nodes, etc.

[0008] The above multiple access technologies 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 (also known 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) on the downlink (DL), 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. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful.

[0057] Detailed description

[0058] 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.

[0059] 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.

[0060] It should be noted that although the aspects herein may be described using terms commonly associated with 5G or New Radio (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).

[0061] 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, 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 base station, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each base station may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a base station and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0062] Base stations 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 base station used for a macrocell may be referred to as a macro base station. A base station used for a picocell may be referred to as a pico base station. A base station used for a femtocell may be referred to as a femtocell or a home base station. Figure 1 In the example shown, base station 110a can be a macro base station for macro cell 102a, base station 110b can be a pico base station for pico cell 102b, and base station 110c can be a femto base station for femto cell 102c. A base station may support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR base station,” “gNB,” “TRP,” “AP,” “B node,” “5G NB,” and “cell” are used interchangeably herein.

[0063] In some respects, a cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station. In some respects, base stations may interconnect with each other and / or interconnect to one or more other base stations or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0064] 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 base station or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a base station). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay base station 110d can communicate with macro base station 110a and UE 120d to facilitate communication between base station 110a and UE 120d. Relay base station may also be referred to as relay station, relay base station, relay, etc.

[0065] Wireless network 100 can be a heterogeneous network comprising different types of base stations (such as macro base stations, pico base stations, femto base stations, or relay base stations). These different types of base stations may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro base stations may have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0066] Network controller 130 can be coupled to a set of base stations and can provide coordination and control over these base stations. Network controller 130 can communicate with the base stations via backhaul. These base stations can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] In some respects, 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 this scenario, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0071] Devices of 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 of 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), the first frequency range (FR1) spanning from 410 MHz to 7.125 GHz and the second frequency range (FR2) spanning 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.

[0072] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may determine that the UE 120 is connected to a wireless network on a first carrier frequency in a first frequency range associated with a data rate lower than a second carrier frequency in a second frequency range, wherein the first frequency range is associated with a first version of the RAT and the second frequency range is associated with a second version of the RAT; determine a bandwidth metric associated with the first carrier frequency in the first frequency range; and display a first visual indicator associated with the first version of the RAT or a second visual indicator associated with the second version of the RAT, at least in part based on the bandwidth metric. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0073] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0074] Figure 2This 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, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T ≥ 1 and R ≥ 1.

[0075] 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 destined 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 232 can process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 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 modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0076] 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 254a to 254r, 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 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 parameters such as Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Received Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0077] 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.

[0078] 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 assemblies, and / or antenna arrays. Antenna panels, antenna groups, antenna element assemblies, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element assemblies, and / or antenna arrays may include coplanar antenna element assemblies and / or non-coplanar antenna element assemblies. Antenna panels, antenna groups, antenna element assemblies, 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 assemblies, 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).

[0079] 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 modulators 254a to 254r (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.

[0080] 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 downlink and / or uplink communications of UE 120.

The transceiver may include (such as) antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or any combination of TX MIMO processor 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 (e.g., as shown with reference to Figures 3A-3D and / or...). Figure 4 (as described).

[0081] 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 displaying RAT status indications based on bandwidth metrics, as described in more detail elsewhere herein.

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...

[0082] In some aspects, UE 120 includes: means for determining that UE 120 is connected to a wireless network on a first carrier frequency in a first frequency range associated with a data rate lower than a second carrier frequency in a second frequency range, wherein the first frequency range is associated with a first version of RAT and the second frequency range is associated with a second version of RAT; means for determining a bandwidth metric associated with the first carrier frequency in the first frequency range; and / or means for displaying a first visual indicator associated with the first version of RAT or a second visual indicator associated with the second version of RAT, at least in part based on the bandwidth metric.

[0083] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0084] As described above, a wireless network deployed in a given geographic area may support one or more RATs and may operate on one or more frequencies. Furthermore, in some cases, the wireless network may support different versions of the RAT to serve UEs with different capabilities and / or provide different service capabilities. For example, in a wireless network supporting NR RAT (often referred to as 5G), a UE may connect to the wireless network on carrier frequencies in a first frequency range (FR1) spanning from 410 MHz to 7.125 GHz (often referred to as the "sub-6 GHz" band) and / or on carrier frequencies in a second frequency range (FR2) spanning from 24.25 GHz to 52.6 GHz (often referred to as the "millimeter wave" (mmW) band). Generally, communication at higher carrier frequencies (e.g., in FR2 and / or other mmW bands such as frequency range 4 (FR4) spanning from 52.6 GHz to 114.25 GHz) can be associated with much higher data rates than communication at lower carrier frequencies (e.g., in FR1). However, because mmW communication has a very short wavelength, it tends to have a shorter propagation distance and is more susceptible to atmospheric attenuation and obstruction. Therefore, wireless networks that enable communication in the mmW band can also enable communication in the sub-6 GHz band to provide greater coverage and / or more reliable service, and so on.

[0085] Because communication in different frequency ranges (e.g., FR1 and FR2) can provide significantly different user experiences, different frequency ranges supported by a particular RAT can be associated with different RAT versions. For example, in an NR network, a carrier frequency in FR1 can be associated with a first version of the NR RAT (e.g., the baseline version, low-band version, or basic version), and a carrier frequency in FR2 that provides a much faster data rate than the carrier frequency in FR1 can be associated with a second version of the NR RAT (e.g., the advanced version or high-band version). Generally, because the UE automatically switches between carrier frequencies in different frequency ranges (e.g., in areas where both frequency ranges are available, and the UE has the ability to communicate using carrier frequencies in either or both frequency ranges), the visual indicators (e.g., icons) displayed by the UE to indicate which version of the RAT is currently active are typically based on the carrier frequency. For example, the UE might display a 5G icon or other visual indicator when it is connected to the NR network on the FR1 carrier frequency, or the UE might display an advanced icon or visual indicator (e.g., 5G+ when the UE is connected to the NR network on the FR2 carrier frequency). However, in some situations, the carrier frequency in FR1 can provide a data rate comparable to that in FR2. In such cases, displaying a baseline 5G icon may mislead users, potentially causing them to inhibit the use of services that rely on high data rates (e.g., gaming or streaming).

[0086] Some aspects described herein relate to technologies and apparatuses (devices) for displaying RAT status indications on a UE based on bandwidth metrics. For example, when a UE connects to a wireless network on a carrier frequency in a first frequency range (e.g., FR1) associated with a data rate lower than that in a second frequency range (e.g., FR2), the UE can determine whether to display an icon or visual indicator associated with a first (e.g., baseline) version of the RAT or a second (e.g., advanced) version of the RAT based on a bandwidth metric associated with the carrier frequency in the first frequency range. For instance, the UE could display a first icon associated with the first version of the RAT (e.g., a base icon (such as "5G") associated with a carrier frequency in FR1) if the bandwidth metric fails to meet a threshold, or a second icon associated with the second version of the RAT (e.g., an advanced icon (such as "5G+") associated with a carrier frequency in FR2) if the bandwidth metric meets the threshold. In this way, the icon or visual indicator displayed on the UE conveys the data rate that the user expects to experience when communicating on the wireless network, rather than simply reflecting the carrier frequency the UE is using to communicate on the wireless network. In this way, when a UE connects to a wireless network on a carrier frequency associated with a bandwidth metric that meets the threshold, a visual indicator can be provided to the user to indicate that the network condition is suitable for participating in services that rely on high data rates.

[0087] Figures 3A-3D This is a diagram illustrating an example 300 associated with displaying a RAT status indication based on bandwidth metrics, according to this disclosure. (See diagram for example.) Figures 3A-3D As shown, Example 300 includes communication between a UE (e.g., UE 120) and one or more nodes (e.g., TRPs and / or base stations) in a wireless network (e.g., wireless network 100). In some aspects, UE 120 may communicate with one or more nodes in the wireless network via a radio access link that may include uplinks and downlinks.

[0088] In some respects, the wireless network can support communication in different frequency ranges that can be associated with different versions of the RAT. For example, as described herein, the wireless network can support communication using carrier frequencies in FR1 associated with a first version of the NR RAT (e.g., the baseline version), and the wireless network can also support communication using carrier frequencies in FR2 associated with a second version of the NR RAT (e.g., the advanced version). However, it will be understood that some aspects described herein are applicable to other frequency ranges (e.g., FR4) and / or other RATs, such as the 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0089] As in Figure 3AAs shown by reference numeral 310 in the accompanying drawings, a UE can connect to a wireless network on a carrier frequency within a first frequency range that is associated with a lower data rate than the carrier frequency within a second frequency range. For example, the carrier frequency within the first frequency range may be included in the sub-6 GHz band of FR1, which is generally associated with a lower data rate than the carrier frequency included in the mmW band of FR2. However, in some cases, the carrier frequency within the first frequency range can provide a data rate comparable to the carrier frequency within the second frequency range (e.g., the carrier frequency within the first frequency range is not necessarily associated with a slower transmission speed). For example, in some aspects, the carrier frequency within the first frequency range can provide a data rate comparable to the second frequency range due to carrier aggregation configurations with large bandwidth, combining multiple component carriers to provide a higher data rate, and / or dual connectivity configurations that enable the UE to communicate simultaneously using different RATs and / or different cell groups.

[0090] Therefore, as in Figure 3A As further illustrated by reference numeral 315 in the accompanying drawings, the UE may display the RAT status indicator based at least in part on a bandwidth metric associated with a carrier frequency within a first frequency range (which may be referred to herein as the FR1 carrier frequency). For example, as will be described in more detail below, the UE may determine the bandwidth metric associated with the FR1 carrier frequency based at least in part on the following: downlink bandwidth associated with the FR1 carrier frequency (e.g., frequency division duplex (FDD) or time division duplex (TDD) configuration), one or more information elements (IEs) received from the radio network that signal the downlink bandwidth associated with the FR1 carrier frequency, the channel bandwidth supported by the UE, a history of past connectivity patterns indicating configured bandwidth associated with one or more cells in the radio network, and / or the bandwidth associated with one or more component carriers in a carrier aggregation or dual connectivity configuration.

[0091] In some respects, as indicated by reference numeral 320, the UE may display a first visual indicator (e.g., a 5G icon) associated with a first version of the RAT, at least in part, based on the fact that a bandwidth metric associated with the FR1 carrier frequency fails to meet a threshold (e.g., when the bandwidth metric for the FR1 carrier frequency is less than or equal to the threshold). Alternatively, as indicated by reference numeral 325, the UE may display a second visual indicator (e.g., a 5G+ or other suitable icon) associated with a second version of the RAT, at least in part, based on the fact that a bandwidth metric associated with the FR1 carrier frequency meets the threshold (e.g., when the bandwidth metric for the FR1 carrier frequency exceeds or is equal to or exceeds the threshold). For example, as described herein, the threshold may have a configurable value under which the FR1 carrier frequency can provide a data rate comparable to that of a carrier frequency in a second (higher) frequency range (which may be referred to herein as the FR2 carrier frequency). In this way, when the bandwidth metric associated with the FR1 carrier frequency meets a threshold, the UE can display a second visual indicator associated with the advanced or high data rate version of the RAT. This second visual indicator is typically only displayed when the UE is connected to the wireless network on the FR2 carrier frequency. In this way, the RAT status indicator displayed on the UE can indicate to the user whether they expect to experience a relatively high or low data rate, enabling the user to make more informed decisions about which services to utilize and / or suppress.

[0092] In some respects, as described above, the UE may use one or more techniques to determine a bandwidth metric, compared with a threshold, to determine whether to display a first visual indicator associated with a first (e.g., baseline or low data rate) version of the RAT or a second visual indicator associated with a second (e.g., advanced or high data rate) version of the RAT. Generally, as described herein, the bandwidth metric may be based at least in part on the downlink bandwidth associated with the FR1 carrier frequency (e.g., because the downlink data rate is generally more important from a user experience perspective). For example, in cases where the FR1 carrier frequency is associated with an FDD configuration (e.g., where separate pairs of frequencies are used for uplink transmission and downlink reception respectively), the bandwidth metric for the FR1 carrier frequency may be the downlink bandwidth associated with the FR1 carrier frequency.

[0093] Alternatively, such as in Figure 3BAs illustrated by reference numeral 330, in cases where the FR1 carrier frequency is associated with a TDD configuration (e.g., where uplink transmission and downlink reception are performed at different times on the same frequency), the bandwidth metric can be the effective downlink bandwidth. For example, in some aspects, the UE can determine the effective downlink bandwidth for an FR1 carrier frequency with a TDD configuration by multiplying the total bandwidth of the FR1 carrier frequency by a scaling factor. For example, since the total bandwidth is shared between the downlink and uplink in a TDD configuration, the scaling factor can have a value ranging from 0 to 1 to subtract the amount of time used for uplink transmission from the total bandwidth. In some aspects, the scaling factor multiplied by the total bandwidth of the FR1 carrier frequency can have a configurable value stored in the UE's memory. For example, in some aspects, the scaling factor can have a configurable value of 0.5 or another suitable value to represent the proportion of time resources expected to be allocated to downlink communication. In one example, if the total bandwidth of the FR1 carrier frequency is 60 MHz and the threshold is 50 MHz, the UE can display a basic 5G icon based on a scaling factor of 0.5 resulting in an effective downlink bandwidth of 30 MHz. However, it will be understood that other suitable values ​​can be used for the threshold and / or configurable values ​​of the scaling factor stored in the UE's memory. In some aspects, the scaling factor can be used to compare the bandwidth associated with a first FR1 carrier frequency with an FDD configuration and the bandwidth associated with a second FR1 carrier frequency with a TDD configuration. Additionally or alternatively, the UE can apply a configurable scaling factor with a value greater than or equal to one to the FR1 carrier frequency with an FDD configuration. For example, in some aspects, the downlink channel bandwidth of the FR1 carrier frequency with an FDD configuration can be multiplied by the scaling factor to reflect that the FDD configuration has separate downlink and uplink bandwidths, while the TDD bandwidth is shared for both downlink and uplink communication.

[0094] In some respects, the UE can determine the scaling factor based on the TDD configuration associated with the FR1 carrier frequency, rather than relying on a configurable value of the scaling factor that may not accurately represent the proportion of time resources allocated to downlink communication. For example, as shown by reference numeral 335, the scaling factor can be based on the proportion of time allocated to downlink communication, which can be determined based on the TDD configuration indicated to the UE by the radio network as a downlink-uplink mode having a periodicity of 0.5 milliseconds (ms), 0.625 ms, 1.25 ms, 2.5 ms, 5 ms, or 10 ms (shown as...). dl-UL-TransmissionPeriodicity ( dl-UL-transmission periodicity Furthermore, downlink-uplink patterns can be associated with the following: a parameter indicating the number of coherent, complete downlink slots at the start of each downlink-uplink pattern (e.g., nrofDownlinkSlots(Number of downlink slots)), a parameter indicating the number of consecutive downlink symbols after the last complete downlink slot (e.g., nrofDownlinkSymbols (Number of downlink symbols)), parameters indicating the number of coherent, complete uplink slots at the end of each downlink-uplink pattern (e.g., nrofUplinkSlots (Number of uplink slots), and parameters indicating the number of coherent uplink symbols preceding the first complete uplink slot (e.g., nrofUplinkSymbols (Uplink symbol count). Therefore, the UE can use various parameters associated with the TDD configuration to calculate the proportion of time resources allocated to downlink communication, which can be used as a scaling factor.

[0095] For example, in an NR network, a 1 ms duration typically includes one (1) slot with a subcarrier spacing (SCS) of 15 kHz, two (2) slots with an SCS of 30 kHz, and four (4) slots with an SCS of 60 kHz, and the number of slots within a 1 ms duration can be scaled proportionally to higher SCS values. Furthermore, a slot typically has fourteen (14) symbols, thereby... nrofDownlinkSlots The parameter indicates the number of complete downlink slots in a downlink-uplink transmission cycle, and nrofDownlinkSymbols The parameter can be divided by 14 to determine the proportion of time slots occupied by multiple consecutive downlink symbols after the last complete downlink time slot. Therefore, the UE can base its decision on... dl-UL- TransmissionPeriodicity The parameters and the SCS associated with the FR1 carrier frequency determine the total number of time slots in a downlink-uplink transmission cycle, and the UE can also base its decisions on these parameters. nrofDownlinkSlots and nrofDownlinkSymbols The parameters determine the total number of downlink slots in a downlink-uplink transmission cycle. In this way, the scaling factor can be expressed by the expression ( nrofDownlinkSlots + ( nrofDownlinkSymbols / X )) / Y To determine, among which X It is the number of symbols in a time slot, and Y It is by dl-UL-TransmissionPeriodicity The parameters and the number of time slots in a cycle defined by SCS.

[0096] For example, if nrofDownlinkSlots The parameter has a value of seven (7). nrofDownlinkSymbols The parameter has a value of seven (7), and a time slot has fourteen (14) symbols, so the total number of downlink time slots in a downlink-uplink transmission cycle is 7 + 7 / 14 = 7.5. Furthermore, if dl-UL-TransmissionPeriodicityThe parameter indicates a 5 ms duration for an FR1 carrier frequency with an SCS of 30 kHz, meaning a downlink-uplink transmission cycle can have a total of ten (10) time slots. In this example, the scaling factor could be 7 + 7 / 14 divided by 10, or 0.75. Therefore, in an example where the total bandwidth of the FR1 carrier frequency is 60 MHz and the threshold for comparison with the bandwidth metric is 60 MHz, the UE can be based on a 0.75 scaling factor for failing to meet that threshold. A total effective bandwidth of 60 MHz = 45 MHz is used to display the basic visual indicator. However, if the total bandwidth of the FR1 carrier frequency is 100 MHz and the same 60 MHz threshold is used, the UE can have 0.75% of that threshold based on the FR1 carrier frequency. 100 MHz = 75 MHz of effective total bandwidth to display advanced visual indicators.

[0097] Additionally or alternatively, in some aspects, the UE may determine the bandwidth metric to be compared with a threshold based at least in part on one or more IEs received from the wireless network. For example, as in Figure 3C As shown by reference numeral 340 in the accompanying drawings, the UE can receive signaling including one or more IEs indicating downlink bandwidth parameters. For example, when the UE is camped on a wireless network, the downlink bandwidth can be used in a System Information Block (SIB) (e.g., NR SIB1). carrierbandwidth (Carrier bandwidth) is indicated by IE. Additionally or alternatively, when the UE is in connected mode in NR self-reliant mode, Evolved Universal Mobile Telecommunications Terrestrial Radio Access (E-UTRA)-NR Dual Connectivity (ENDC) modem, and / or NR Dual Connectivity (NRDC) mode, the downlink bandwidth can be indicated using Radio Resource Control (RRC) messages (e.g., RRCReconfiguration The message (RRC reconfiguration) carries downlinkChannelBW-PerSCS-List ( Downlink Channel BW-per SCS-column surface ) IE is used to indicate. Generally speaking, carrierbandwidth and downlinkChannelBW-PerSCS-List An IE can indicate the downlink bandwidth in units of resource blocks (RBs) for the FR1 carrier frequency. Therefore, as shown by reference numeral 345, the UE can map the downlink bandwidth values ​​indicated in one or more IEs to a bandwidth metric for the FR1 carrier frequency.

[0098] For example, as shown by reference numeral 350, the UE may store a lookup table for converting downlink bandwidth from RB units to a bandwidth metric based on the SCS of the FR1 carrier frequency. Therefore, the UE can determine the row in the lookup table corresponding to the SCS of the FR1 carrier frequency, and can then locate the value of the downlink bandwidth indicated in one or more IEs within the row corresponding to the SCS of the FR1 carrier frequency to convert that downlink bandwidth from RB units to a bandwidth metric. For example, if carrierbandwidth IE and / or downlinkChannelBW-PerSCS-List If the IE indicates the downlink bandwidth of 162 RBs for an FR1 carrier frequency with an SCS of 30 kHz, then the UE can determine that the bandwidth metric for the FR1 carrier frequency is 60 MHz. In this case, the visual indicator displayed on the UE can correspond to a high or high data rate icon based on the bandwidth metric meeting (e.g., equaling) a threshold of 60 MHz. In another example, if carrierbandwidth IE and / or downlinkChannelBW-PerSCS-List If the IE indicates the downlink bandwidth of 270 RBs for an FR1 carrier frequency with a 15 kHz SCS, the UE can map the indicated value of the downlink bandwidth to a 50 MHz bandwidth metric. In this case, the visual indicator displayed on the UE can correspond to a base or low data rate icon based on the fact that the bandwidth metric fails to meet (e.g., equal to or exceed) a 60 MHz threshold.

[0099] Generally speaking, carrierbandwidth The downlink bandwidth indicated in the IE corresponds to the maximum downlink bandwidth that can be supported in the current NR cell. However, in some cases, the UE may or may not support this bandwidth. carrierbandwidth The maximum downlink bandwidth indicated in the IE. For example, as shown by reference numeral 355 in the attached figure, the UE may have a set of supporting channel bandwidths (in Figure 3C The examples shown include capabilities of {100 MHz, 60 MHz, 40 MHz, and 20 MHz}. Therefore, in order to... carrierbandwidth The downlink bandwidth indicated in the IE is mapped to a bandwidth metric for the FR1 carrier frequency, which the UE can determine accordingly. carrierbandwidth The maximum downlink bandwidth indicated in the IE, and the bandwidth metric can be the maximum downlink bandwidth supported by the UE that is less than or equal to the maximum downlink bandwidth supported by the current cell. For example, if carrierbandwidthIf the IE indicates a maximum downlink bandwidth of 70 MHz and the set of channel bandwidths supported by the UE includes {100 MHz, 60 MHz, 40 MHz, and 20 MHz}, then the bandwidth metric can be 60 MHz (the maximum value of the maximum downlink bandwidth less than or equal to 70 MHz in this set). In this example, the UE can display a high or high data rate icon based on a threshold of 60 MHz (or lower) or a basic or low data rate icon based on a threshold higher than 60 MHz.

[0100] In some respects, the aforementioned techniques can generally be used to determine the maximum downlink bandwidth supported by a UE given the maximum downlink bandwidth supported by the current cell. However, in some cases, the wireless network may not be able to guarantee the bandwidth required to meet the maximum downlink bandwidth supported by the UE. Therefore, in some respects, the UE can use the past connectivity mode history of the current cell to determine the bandwidth metric. For example, as shown by reference numeral 360, the UE can maintain a database storing the past connectivity mode history of different cells in the wireless network, where each cell can be represented in the database by a Cell Global Identity (CGI) based on the Public Land Mobile Network (PLMN) identity and the cell identity. Therefore, when the UE is in connectivity mode in a particular cell, the UE can receive a signal carrying an indication of the downlink channel bandwidth configured for the UE when the UE is in connectivity mode. downlinkChannelBW-PerSCS IE's RRC message (e.g., RRCReconfiguration information).

[0101] In some aspects, when the UE is in connected mode, it can store the maximum configured downlink channel bandwidth for each cell in a database. This maximum configured downlink channel bandwidth can be used as a bandwidth metric in idle or inactive modes. For example, if the database of past connected mode history indicates that 40 MHz is the maximum bandwidth configured for the UE in the current cell, the UE can determine that the 40 MHz maximum bandwidth is applicable in idle or inactive modes and can display a base or low data rate icon based on the 40 MHz maximum bandwidth failing to meet the 60 MHz threshold. However, if the UE enters connected mode on the current cell and downlinkChannelBW-PerSCS If the UE is configured with a larger downlink channel bandwidth of 60 MHz, the UE can update entries in the database of past connectivity patterns. In this scenario, if the UE later enters an idle or inactive mode on the current cell, the UE can display an advanced or high data rate icon based on the maximum configured bandwidth of 60 MHz meeting the 60 MHz threshold.

[0102] Additional or alternative land, such as in Figure 3DAs illustrated by reference numeral 365, a UE can determine a bandwidth metric to be compared to a threshold based at least in part on the carrier aggregation or dual connectivity configuration associated with that UE. For example, as shown by reference numeral 370, a UE can be associated with a carrier aggregation configuration in which multiple FR1 component carriers are configured for that UE. In such cases, when the UE has a carrier aggregation configuration, the UE can determine the bandwidth metric by summing the bandwidth values ​​of all downlink component carriers, including all downlink component carriers in the primary cell (PCell) and all downlink component carriers in one or more secondary cells (SCell). For example, reference numeral 370 depicts an example in which the UE is operating with an NR self-reliant carrier aggregation configuration having two (2) FR1 component carriers associated with an FDD configuration and a downlink bandwidth of 40 MHz for each component carrier. In this example, the aggregated bandwidth of all downlink component carriers is 80 MHz, which could cause the UE to display a high or high data rate icon based on this 80 MHz bandwidth metric meeting a threshold of 60 MHz. Furthermore, it will be understood that the other techniques described above can be used to determine the bandwidth metric for each downlink component carrier (e.g., in cases where the downlink component carrier has a TDD configuration and / or one or more IEs are used to indicate the downlink bandwidth).

[0103] In another example, as shown by reference numeral 375, a UE may be associated with an ENDC configuration in which the UE communicates using 4G or LTE RAT on an LTEPCell or primary cell group (MCG) and also on an NR RAT on a secondary cell group (SCG). In such a case, when the UE has an ENDC configuration in which the SCG associated with the NR RAT includes one or more FR1 component carriers, the UE can determine the bandwidth metric by summing the bandwidth values ​​of all downlink component carriers in that SCG (including all downlink component carriers in the primary and secondary cells (PSCell) and any SCell). For example, reference numeral 375 depicts an example in which the UE is operating with an ENDC configuration having two (2) FR1 component carriers in the SCG, where each FR1 component carrier is associated with a bandwidth metric of 20 MHz (e.g., based on FDD or TDD configuration, downlink bandwidth indicated in one or more IEs, the set of bandwidth values ​​supported by the UE, or a history of past connectivity modes, etc.). In this example, the aggregated bandwidth of all downlink component carriers in the SCG is 40 MHz, which may cause the UE to fail to meet the 60 MHz threshold based on this 40 MHz bandwidth metric and thus display a base or low data rate icon.

[0104] In another example, as shown by reference numeral 380, the UE can be associated with an NRDC configuration where the MCG and SCG are each associated with either 5G or NR RAT. In such a case, when the UE has an FR1+FR1 NRDC configuration (e.g., where all component carriers in the MCG and SCG are FR1 carrier frequencies), the UE can determine the bandwidth metric by summing the bandwidth values ​​of all downlink component carriers in the MCG and SCG (including the PCell in the MCG, any SCell in the MCG, the PSCell in the SCG, and all downlink component carriers in any SCell in the SCG). For example, reference numeral 380 depicts an example where the UE is operating with an NRDC configuration where the PCell in the MCG is configured on an FR1 carrier frequency with a bandwidth metric of 40 MHz (which alone may not meet the 60 MHz threshold). However, as further shown, the SCG includes two (2) FR1 component carriers, each associated with a bandwidth metric of 20 MHz. In this example, the aggregated bandwidth of all downlink component carriers in the MCG and SCG is 80 MHz, which can cause the UE to display an advanced or high data rate icon based on the 80 MHz bandwidth metric meeting the 60 MHz threshold.

[0105] In another example, as shown by reference numeral 385, the UE can be associated with an FR1+FR2 NRDC configuration, where the component carriers in the MCG include the FR1 carrier frequency and the component carriers in the SCG include the FR2 carrier frequency associated with a higher data rate. In this case, because the FR2 carrier frequency is associated with the mmW band providing a higher data rate, the UE can display the advanced or high data rate icon based on the large bandwidth associated with the FR2 carrier frequency.

[0106] As indicated above, Figures 3A-3D This is provided as an example. Other examples may differ from the one provided. Figures 3A-3D The example described.

[0107] Figure 4 This is a diagram illustrating an example procedure 400 performed by a UE according to this disclosure.
