    [001] [001] The present application claims the priority and benefit of US Provisional Patent Application 62 / 508,834, filed on May 19, 2017 and US Provisional Patent Application 62 / 516,537, filed on June 7, 2017, which are incorporated in this document as a reference, in their entirety. TECHNICAL FIELD
    [002] [002] This order relates to wireless communication systems and, more particularly to the provision of an indication to a user that a user equipment (UE) can connect to a Novo Rádio (NR) network. INTRODUCTION
    [003] [003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messages, broadcast and so on. These systems may be able to support communication with multiple users by sharing available system resources (for example, time, frequency and power). Examples of such multiple access systems include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA) and division multiple access systems orthogonal frequency (OFDMA), (for example, a Long Term Evolution (LTE) system. A wireless multiple access communication system can include multiple base stations (BSs), each simultaneously supporting communication to multiple wireless devices. which may otherwise be known as user equipment (UE).
    [004] [004] To meet the growing demands for expanded connectivity, wireless communication technologies or RATs are advancing from LTE technology to a new next generation (NR) radio technology. For example, NR can provide lower latency and a higher bandwidth or throughput than LTE. One approach to providing the enhanced NR functionality is to deploy an NR network within an LTE network. In other words, the NR network can be superimposed over the LTE network with overlapping coverage areas, in which the NR network and the LTE network can operate through overlapping spectra. Consequently, the coexistence and efficient use of resources between LTE and NR can be important. BRIEF SUMMARY OF SOME EXAMPLES

    [0023] [0023] The detailed description presented below, together with the attached drawings, is intended as a description of various configurations and is not intended to represent only the configurations in which the concepts described in this document can be practiced. The detailed description includes specific details for the purpose of providing a complete understanding of the various concepts. However, it will be evident to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in the form of a block diagram in order to avoid obscuring such concepts.
    [0024] [0024] The techniques described in this document can be used for various wireless communications networks such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier FDMA (SC-FDMA) and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement "a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Broadband CDMA (WCDMA) and other CDMA variants. Cdma2000 covers standards I1IS-2000, 1S-95 and IS-856. A TDMA network can implement a radio technology as a Global System for Mobile Communications (GSM) An OFDMA network can implement a radio technology such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi) IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and
    [0025] [0025] The present application describes mechanisms to provide a user with an indication that the user requirement (UE) is connected to a new radio network (NR). Figure 1 illustrates a wireless communication network 100 according to the modalities of the present disclosure. Network 100 includes BSs 105, UEs 115, and a core network 130. In some embodiments, network 100 operates over a shared spectrum. The shared spectrum may be unlicensed or partially licensed to one or more network operators. Access to the spectrum can be limited and can be controlled by a separate coordinating body. In some embodiments, network 100 may be an LTE or LTE-A network. In still other modalities, the network 100 can be a millimeter wave network (mmW), a new radio network (NR), a 5G network, or any other network successor to LTE. The network 100 can be operated by more than one network operator. wireless resources can be partitioned and arbitrated between different network operators for coordinated communication between network operators over network 100.
    [0026] [0026] BSs 105 can communicate wirelessly with UEs 115 through one or more BS antennas. Each BS 105 can provide communication coverage for a respective geographic coverage area 110. In 3GPP, the term “cell” can refer to that specific geographical coverage area of a BS and / or a BS subsystem that serves the area of coverage, depending on the context in which the term is used. Accordingly, a BS 105 can provide communication coverage to a macro cell, a peak cell, a femto cell and / or other types of cell. A macro cell, in general, covers a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. A peak cell, in general, can cover a smaller geographic area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femto cell can also cover a relatively small geographical area (for example, a residence) and, in addition to unrestricted access, it can also provide access restricted by UEs having an association with the femto cell (for example, UEs in a group of subscribers (CSG), UEs for home users, and the like). A BS for a macro cell can be called a macro BS. A BS for a peak cell can be called a peak BS. A BS for a femto cell can be called a BS femto or domestic BS. In the example shown in Figure 1, BSs 105a, 105b and 105c are examples of macro BSs for coverage areas 110a, 110b and 110c, respectively. BSs 105d is an example of a BS peak or BS femto for coverage area 110d. As will be recognized, a BS 105 can support one or multiple cells (for example, two, three, four, and the like).
    [0027] [0027] Communication links 125 shown on network 100 may include uplink (UL) transmissions from a UE 115 to a BS 105, or downlink (DL) transmissions from a BS 105 to a UE 115 UEs 115 can be dispersed over network 100, as shown, and each UE 115 can be stationary or mobile. A UE 115 can also be called a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device , a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a customer, or any other suitable terminology. An UE 115 can also be a cell phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a tablet, a laptop, a cordless phone, a personal electronic device, a portable device, personal computer, a local wireless circuit station, an Internet of Things (IoT) device, an Internet of Everything (I0E) device, a machine-type communication device (MTC),
    [0028] [0028] BSs 105 can communicate with main network 130 and with each other. Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing or mobility functions. At least some of the BSs 105 (for example, which can be an example of an evolved NodeB (eNB), a next generation NodeB (gNB), or an access node controller (ANC)) can interface with the network. core 130 via backhaul links 132 (eg Sl, S2, etc.) and can perform radio configuration and program communication with UEs 115. In several instances, BSs 105 can communicate, either directly or indirectly (for example, through core network 130), with each other through backhaul links 134 (for example, Xl, X2, etc.), which can be wired or wireless communication links.
    [0029] [0029] Each BS 105 can also communicate with several UEs 115 through several other BSs 105, where BS 105 can be an example of an intelligent radio unit. In alternative configurations, several functions of each BS 105 can be distributed across multiple BSs 105 (for example, radio units and access network controllers) or consolidated into a single BS 105.
    [0030] [0030] In some implementations, network 100 uses orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on UL. OFDM and SC-FDM partition the system bandwidth into multiple (K)
    [0031] [0031] In one embodiment, BSs 105 can allocate or schedule transmission resources (for example, in the form of time-frequency resource blocks) for DL and UL transmissions on network 100. DL refers to the direction of transmission from a BS 105 to a UE 115, while the UL refers to the direction of transmission from a UE 115 to a BS 105. Communication can be in the form of radio frames. A radio frame can be divided into a plurality of subframes, for example, about 10. Each subframe can be divided into slots, for example, about 2. Each slot can be further divided into min-slots, as described in more details in this document. In a frequency division duplexing (FDD) mode, simultaneous UL and DL transmissions can occur in different frequency bands. For example, each subframe includes a UL subframe in an UL frequency band and a DL subframe in a DL frequency band. In a time division duplexing (TDD) mode, UL and DL transmissions occur at different times using the same frequency band. For example, a subset of the subframes (for example, DL subframes) in a radio frame can be used for DL transmissions and another subset of the subframes (for example, UL subframes) in the radio frame can be used for radio transmissions. UL.
    [0032] [0032] DL subframes and UL subframes can be further divided into several regions. For example, each DL or UL subframe can have predefined regions for transmitting reference signals, control information and data. Reference signals are predetermined signals that facilitate communication between BSs 105 and UEs 115. For example, a reference signal can have a specific pilot pattern or structure, in which pilot tones can span a bandwidth or bandwidth. operating frequency, each positioned at a predefined time and at a predefined frequency. For example, a BS 105 can transmit cell-specific reference signals (CRSs) and / or channel status information - reference signals (CSI-RSs) to allow a UE 115 to estimate a DL channel. Similarly, an UE 115 can transmit audible reference signals (SRSs) to allow a BS 105 to estimate an UL channel. Control information can include resource assignments and protocol controls. The data can include protocol data and / or operational data. In some embodiments, BSs 105 and UEs 115 can communicate using independent subframes. An independent subframe can include a portion for DL communication and a portion for UL communication. An independent subframe can be centered on DL or centered on UL. A DL-centered subframe may include a longer duration for DL communication than UL communication. A UL-centered subframe may include a longer duration for UL communication than UL communication.
    [0033] [0033] In one embodiment, a UE 115 that attempts to access network 100 can perform an initial cell search by detecting a primary synchronization signal (PSS) from a BS 105. PSS may allow period synchronization and may indicate a sector identity value (for example, 0, 1, 2, etc.). The UE 115 can then receive a secondary synchronization signal (SSS). The SSS can enable radio frame synchronization, and can provide a cell identity value, which can be combined with the PSS identity value to identify the physical cell identity. SSS can also allow the detection of a duplex mode and a cyclic prefix length. Both the PSS and the SSS can be located in a central portion of a carrier, respectively. Upon receipt of the PSS and SSS, the UE 115 can receive a master information block (MIB), which can be transmitted on the physical broadcast channel (PBCH). The MIB can contain system bandwidth information, a system frame number (SFN), and a Physical ARQ Hybrid Indicator (PHICH) configuration. After decoding the MIB, the UE 115 can receive one or more blocks of system information (SIBs). For example, the SIBl may contain cell access parameters and programming information from other SIBs. Decoding SIB 1 can allow UE 115 to receive SIB2. The SIB2 may contain radio resource configuration (RRC) configuration information related to random access channel (RACH) procedures, paging, physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) , power control, SRS, and cell bus. After obtaining the MIB and / or the SIBs, the UE 115 can perform random access procedures to establish a connection with BS 105. After establishing the connection, the UE 115 and BS 105 can enter a normal operating stage, in that operational data can be exchanged.
    [0034] [0034] In some embodiments, UEs 115 and BSs 105 may be operated by multiple network operators or network operating entities and may operate on a spectrum of shared radio frequencies, which may include licensed or unlicensed frequency bands . The shared spectrum can be partitioned in time for sharing between multiple operational entities on the network to facilitate coordinated communication. For example, on network 100, BS 105a and UE l115a can be associated with an operational entity on the network, while BS 105b and UE 115b can be associated with another operational entity on the network. With the sharing of the time of the shared spectrum according to the operational entities of the network, the communication between BS 105a and UE l115a and the communication between BS 105b and UE 115b can occur during the respective periods of time and can benefit of a totality of designated shared spectrum.
    [0035] [0035] In one embodiment, network 100 can support multiple networks with different RAT technologies.
    [0036] [0036] Figure 2 illustrates a network system 200 according to the modalities of the present disclosure; System 200 can correspond to a portion of network 100 and include an LTE-NR integration architecture with dual connectivity. The NR network can be unstable, as it has no ubiquitous coverage and has a small cell radius. To overcome this problem, it may be desirable for an UE 115 to connect to both the LTE network and the NR network. In one embodiment, the NR network can be superimposed on the LTE network. UE 202 supports dual connectivity, which allows UE 202 to connect to both the LTE and NR networks simultaneously. UE 202 supports a non-independent mode that uses the LTE network to support connectivity from UE 202 to the NR network. If UE 202 is connected to the NR network, UE 202 is also connected to the LTE network. The NR network can be a "best effort" network that is anchored in the LTE network. For example, if UE 202 is within the NR network coverage, UE 202 will use the NR network to transmit data. In this example, UE 202 takes advantage of the lower latency, higher bandwidth and / or higher transfer rate offered by the NR network, while taking advantage of the stable links provided by the LTE network. If the connection to the NR network is not stable or weak, the UE 202 can connect to the LTE network without connecting to the NR network.
    [0037] [0037] The UE 202 can transmit data using an Evolved Packet Core (EPC) 204, which is the core network of the LTE system. EPC 204 includes a Mobility Management Entity (MME) 205 and a P / SGW 207. Data traffic can be divided. For example, the UE 202 can transmit LTE Radio Link Control (RLC) / Media Access Control (MAC) 206 to an eNB 208 and transmit NR 210 RLC / MAC and LTE Packet Data Convergence Protocol / NR (PDCP) 212 to gNB 214. A split carrier can be located in gNB 214, and the data sent to eNB 208 will be merged into gNB 214 with other data. The gNB 214 can aggregate the data and send it to the P / SGW 207 using the S1I-U interface. In addition, signaling information can be passed through eNB 208 to MME 205 using the SI-MME interface. Although Figure 2 illustrates an LTE-NR / EPC system, it is not intended to be limiting and other modalities may include different systems. For example, in another embodiment, the system may include an LTE-NR / NGC system.
    [0038] [0038] In some embodiments, UE 202 may be, at most, in a state of a plurality of states. If the UE 202 is connected to a first network (for example, NR network, 5G network, etc.) and a second network (for example, LTE network, 4G network, etc.) simultaneously, the UE 202 is on a first connected mode. In this example, UE 202 can be connected to both the NR network and the LTE network. The LTE network can be associated with an LTE cell, and the NR network can be associated with an NR cell. If UE 202 is connected to the second network, but not to the first network, UE 202 is in a second connected mode. In this example, UE 202 can be connected to the LTE network, but not to the NR network. If UE 202 is inactive, UE 202 is in idle mode connected to the second network, but not to the first network. In this example, UE 202 may be camped on the LTE network. UE 202 may be in idle mode if UE 202 has no data to transmit or is not receiving data from another device.
    [0039] [0039] If the UE 202 is in the second connected mode or in the idle mode, however, the UE 202 may be unable to know whether the UE 202 is within coverage by the NR network or be able to receive the signal strength information of NR. For example, if UE 202 is in idle mode, UE 202 monitors the LTE network, not the NR network. Consequently, the UE 202 cannot display an icon (for example, 5G icon cover bar) on a display screen coupled to the UE 202 indicating that the UE 202 is connected to the NR network. The icon includes a mobile network signal strength indicator associated with the 5G network / NR network.
    [0040] [0040] If UE 202 knows the frequency at which the NR network operates, UE 202 may be able to determine whether UE 202 is within coverage by the NR network. If Oo UE 202 knows the frequency, UE 202 can tune to that frequency and transmit data.
    [0041] [0041] Figure 3 is a block diagram of an exemplary UE 300 according to the modalities of the present disclosure. UE 300 can be UE 115, 202 as discussed above. As shown, the UE 300 may include a processor 302, a memory 304, a user interface (UI) 308, a transceiver 310 including a receiver 311, a modem subsystem 312 and a radio frequency (RF) unit 314 and one or more antennas 316. These elements can be in direct or indirect communication with each other, for example, through one or more buses.
    [0042] [0042] Processor 302 may include a central processing unit (CPU), digital signal processor (DSP), application specific integrated circuit (ASIC), controller, field programmable port array device (FPGA) ), another hardware device, a firmware device or any combination thereof configured to perform the operations described in this document. The processor 302 can also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
    [0043] [0043] Memory 304 may include a cache memory (for example, a 302 processor cache memory), random access memory (RAM), magnetoresistive RAM (MRAM), read memory (ROM), programmable read memory (PROM ) erasable programmable read memory (EPROM), electrically erasable programmable read memory (EEPROM), flash memory, solid state memory device, hard disk drives, other forms of volatile and non-volatile memory or a combination of different types of memory. In one embodiment, memory 404 includes a non-temporary, computer-readable medium. Memory 304 can store instructions 306. Instructions 306 can include instructions that, when executed by processor 302, cause processor 302 to perform the operations described in this document with reference to UEs 115, 202 in conjunction with the modalities of the present disclosure . Instructions 306 can also be called a code. The terms "instructions" and "code" should be interpreted widely to include any type of computer-readable instruction (s). For example, the terms "instructions" and "code" can refer to one or more programs, routines, subroutines, functions, procedures, etc. “Instructions” and “code” can include a single computer-readable instruction or many computer-readable instructions.
    [0044] [0044] As shown, transceiver 310 can include receiver 311, modem subsystem 312 and RF unit 314. Transceiver 310 can be configured to communicate bidirectionally with other devices, such as BSs 105. UE 202 supports dual connectivity to the LTE network and the NR network. Modem subsystem 312 can be configured to modulate and / or encode data from memory 304, according to a modulation and encoding scheme (MCS), for example, a low density parity check (LDPC) encoding scheme , a turbo coding scheme, a convolutional encoding scheme, a digital beam formation scheme, etc. The RF unit 314 can be configured to process (for example, perform analog to digital or digital to analog conversion, etc.) modulated / encoded data from modem subsystem 312 (in outgoing transmissions) or from transmissions that originate from another source, such as a UE 115 or a BS
    [0045] [0045] The RF unit 314 can supply the modulated and / or processed data, for example, data packets (or, more generally, data messages that may contain one or more data packets and other information), to the antennas 316 for transmission to one or more other devices. This may include, for example, the transmission of CQI and / or SRS reports according to the modalities of the present disclosure. The 316 antennas can additionally receive data messages transmitted from other devices. Antennas 316 can provide data messages received for processing and / or demodulation on transceiver 310. Antennas 316 may include multiple antennas of similar or different designs to maintain multiple transmission links. The RF unit 314 can configure the antennas 316.
    [0046] [0046] Receiver 311 obtains information 315,
    [0047] [0047] Figure 4 illustrates a 400 call flow according to the modalities of the present disclosure. In the example illustrated in Figure 4, an LTE 404 cell transmits a system information block (SIB) 408 (for example, SIBl, SIB2, or ENDC indication bit) with an indication of the possibility that the UE 402 is within the coverage by the NR network, which can be supported by an NR 406 cell. The SIB 408 can include a bit indicating whether UE 202 is within coverage by the NR network. The LTE 404 cell can broadcast SIBs. Referring to Figure 3, receiver 311 can obtain information 315 by receiving SIB 408 with an indication of the possibility that UE 202 is within coverage by the NR network.
    [0048] [0048] The SIB 408 includes an indication bit indicating whether the UE 202 is within the coverage by the NR network. If the indication bit indicates that UE 202 is within coverage by the NR network, receiver 311 can pass coverage / signal strength 410 with that information to UI 308, which can display a coverage 5G icon based on coverage / signal strength 410. If the indication bit indicates that UE 202 is not within coverage by the NR network, receiver 311 can pass signal coverage / strength 410 with this information to UI 308, which will not report coverage by the NR network. The receiver 311 can obtain these SIBs regardless of whether the UE 202 is actually within coverage by the NR network. The UE 402 can connect to the LTE network and the NR network, if appropriate.
    [0049] [0049] Figure 5 illustrates a flow of calls 500 according to the modalities of the present disclosure. In the example illustrated in Figure 5, an LTE 504 cell transmits a SIB including a list of NR frequencies. The NR frequency list includes one or more NR frequencies on which the NR network operates. A SIB can include the list of NR frequencies. A new parameter of an existing SIB or a new SIB (for example, SIB 22) can include the list of frequencies. In addition, an NR 506 cell transmits a synchronization signal block (SS) and the CSI-RS. In addition, the new SIB or new parameter in the existing SIB may include additional SS block configuration information, for example, subcarrier spacing, schedule for transmitting SS blocks, periodicity for transmitting the SS burst set that has multiple SS blocks, number of SS blocks per SS burst set, etc. In addition, the new SIB or the new parameter in the existing SIB can include additional CSI-RS information, for example, schedule for transmitting CSI-RS. Referring to Figure 3, receiver 311 can obtain information 315 upon receipt of the SIB which includes the frequency list of the LTE 504 cell and upon receipt of the SS block and CSI-RS from the NR 506 cell. NR 506 cell supports the NR network. Additionally, the UE 502 can be in an idle mode or any of the connected modes (for example, connected to both the LTE network and the NR network, or connected only to the LTE network).
    [0050] [0050] UE 502 can use a variety of techniques to determine if UE 502 is within coverage by the NR network. In some modalities, if the UE 502 is connected to both the LTE network and the NR network, the UE 502 actively receives the NR and the UE 502 reports the CSI and Radio Link Monitoring (RLM). The UE 502 takes advantage of these measurements to display the 5G icon.
    [0051] [0051] In some modalities, if the UE 502 is connected to the LTE network, but not to the NR network, the UE 502 can measure the NR regarding the addition of dual connectivity. The LTE cell 504 configures an NR measurement object that contains the list of frequencies from the NR network and that the UE 502 measures. The UE 502 can take advantage of the measurement result to display the 5G icon. In one example, the UE 502 uses the frequency list to search for the SS block in each of the frequencies listed in the frequency list. The SS block includes NR-PSS, NR-SSS, and NR-PBCH for a specific frequency. The NR-PSS can be used to identify sector symbol and identity timing. NR-SSS can be used to identify cell identity. The NR-PBCH can be used to indicate the
    [0052] [0052] For one or more frequencies listed in the frequency list, the UE 502 receives from the NR 506 cell an SS block that includes an NR-PRR, an NR-SSS, and an NR-PBCH associated with the respective frequency. The UE 502 measures a signal strength from NR-PSS and NR-SSS and determines whether the signal strength satisfies a threshold. In response to a determination that the signal strength meets the threshold, the UE 502 determines to display the 5G icon. Consequently, UI 308 displays the icon. In response to a determination that the signal strength does not meet the threshold, the UE 502 determines that the 5G icon is not displayed. Consequently, UI 308 reports on the screen that there is no coverage by the NR network. UI 308 can report that there is no coverage by the NR network by not displaying the 5G icon on the screen. If the LTE 504 cell broadcasts a new SIB including the NR frequency list, but there is no NR measurement object, the UE 502 can use those included in the SIB to measure the NR and display the 5G icon, if appropriate. If, however, the SIB does not include the list of NR frequencies and there is also no NR measurement object, the UE 502 may report that there is no coverage by the NR network.
    [0053] [0053] In some embodiments, if the UE 502 determines the NR-PSS symbol outline and the cell identity by the NR-SSS and NR-PSS, the UE 502 can measure the signal strength of the NR-PSS and NR -SSS. If the signal strength is greater than a threshold, the UE 502 can determine that the UE 502 is within coverage by the NR network, and thus, the UI 308 can display the 5G icon on a screen coupled to the UE 502. If if this is not the case, the UE 502 can determine that the UE 502 is not covered by the NR network and, consequently, report on the screen that there is no coverage by the NR network.
    [0054] [0054] In some embodiments, for one or more frequencies listed in the frequency list, the UE 502 receives from the NR 506 cell an SS block that includes an NR-PSS, an NR-SSS, and an NR-PBCH (Physical Channel Broadcast) associated with the respective frequency. The UE 502 determines the system frame number information and NR bandwidth for a frequency channel associated with the SS block, and measures a CSI-RS (Channel State Information Reference Signal) based on the system frame number information and NR bandwidth to determine if UE 502 is within coverage by the NR network. The UE 502 acquires the NR-PBCH to determine the system frame number information and the NR bandwidth of the frequency channel. After UE 502 acquires NR-PSS and NR-SSS, UE 502 measures CSI-RS to determine if UE 502 is within coverage by the NR network.
    [0055] [0055] In some embodiments, if the UE 502 is in idle mode and the LTE 504 cell broadcasts a new SIB including the NR frequency list, the UE 502 can measure the NR and display the 5G icon, if appropriate. If the UE 502 is in idle mode and there is no list of frequencies included in the SIB, then the UE 502 may report that there is no coverage over the NR network. An NR LTE SIB can include more parameters, for example, reselection of LTE cells to 5G. For a UE in non-autonomous mode, the UE can use a parameter other than the SIB to determine whether to display the 5G bar on the 5G icon. Alternatively, an existing SIB, for example, SIB5, can signal neighboring NR frequencies.
    [0056] [0056] Figure 6 illustrates a 600 call flow for configuring fast dual connectivity according to the modalities of the present disclosure. In the example illustrated in Figure 6, a UE 602 is in idle mode. An LTE 604 cell transmits a SIB including a list of frequencies. A NR 606 cell transmits an SS and CSI-RS block. UE 602 receives the SIB from the LTE 604 cell and Oo the SS block and the CSI-RS from the NR 606 cell.
    [0057] [0057] If the UE 602 wishes to transmit or receive data, the UE 602 can configure an RRC connection. The UE 602 can send the NR measurement results to the LTE 604 cell. The UE 602 can prepare the measurement in advance and send the connection configuration information to the LTE 604 cell. The LTE 604 cell can determine that the UE 602 has a strong signal strength associated with the NR network. During the RRC connection setup, the LTE cell 604 can configure the UE 602 to be in dual connectivity mode. After the UE 602 is in dual connectivity mode, the UE 602 can transmit and receive data from the LTE network and the NR network. An advantage of this feature may allow the display of a precise bar associated with the 5G icon. Additionally, this may allow reselection of LTE-to-NR in the independent 5G mode of the future.
    [0058] [0058] In some embodiments and with reference to Figure 3, receiver 311 can obtain information 315 upon receipt of a measurement object that is configured by the LTE cell. The measurement object can include a frequency list that specifies the frequencies on which the NR network operates and provides the bandwidth of a frequency channel. The UE can search for one or more frequencies according to the measurement object and measure at one or more frequencies to determine if the US is within coverage by the NR network. In one example, the measurement object is an NR measurement object and the frequency list specifies the frequencies on which the NR network operates. If the UE receives the measurement object and the frequency channel bandwidth, the UE can more easily know where to look for and measure the signal from the NR cells.
    [0059] [0059] If the UE is in dual connectivity mode and connected to both the LTE network and the NR network, the discussion referring to Figure 5 can be applied. If the UE is connected to the LTE network, but not to the NR network, the UE can use the measurement object (for example, NR measurement object) to search and measure the NR. The LTE cell can configure the measurement object. If the UE has previously connected to the LTE cell, the UE may have already received a measurement object from the LTE cell and the measurement object has been cached. In some instances, the UE can retrieve that cached measurement object. If the UE does not receive a measurement object or does not have a measurement object cached for that LTE cell or tracking area, then the UE does not perform a search for NR. In this example, the UI reports on the screen that there is no coverage by the NR network.
    [0060] [0060] If the UE is in idle mode, the UE continues to cache the measurement objects from when the UE was in connected mode, by LTE cell or TAI (tracking area). The UE can use the cached measurement object per LTE or TAI cell to know the NR coverage next to the current encamped cell to search and measure the NR and display the 56G icon.
    [0061] [0061] It can be advantageous to provide optimization opportunities to the UE. For example, in some embodiments and with reference to Figure 3, receiver 311 can obtain information 315 by retrieving it from an acquisition database (not shown) which stores the information. The acquisition database can store information including the frequencies (for example, NR frequencies) within which the NR network operates. The UE can use the acquisition database to determine NR cell coverage while the UE is in idle mode.
    [0062] [0062] Additionally, before the release of the RRC connection (see Figure 6), the UE has some frequency information regarding the NR network. After releasing the RRC connection in dual connectivity, the UE may not be connected to the LTE network or the NR network. The UE can continue to use the NR frequency for indication or measurement of coverage for some time, after that specific frequency may still be applicable for some time.
    [0063] [0063] In addition, to save energy, O
    [0064] [0064] In some instances, the UE may connect to the NR network, however other factors may advocate against allowing the UE to do so. For example, determining whether to display an icon indicating that the UE is connected to a network can include the UE determining whether the UE has a subscription to the network. If the UE does not have a subscription on the network (for example, NR network), it may be desirable not to allow the UE to display the icon (for example, 5G icon). Figure 7 illustrates a call flow 700 according to the modalities of the present disclosure. The LTE cell 704 can transmit the SIB including the frequency list, and the NR 706 cell can transmit the SS block and the CSI-RS. UE 702 determines whether UE 702 has a subscription to the NR network. In response to a determination that UE 702 does not have a subscription to the NR network, UI 702 reports on screen that UE 702 is not within coverage by the NR network. UE 702 may include a Universal Integrated Circuit Card (UICC) indicating whether UE 702 has a subscription to the NR network.
    [0065] [0065] In another example, determining whether to display the 5G icon may include determining the UE if the UE is prevented from connecting to the NR network. Figure 8 illustrates a flow of calls 800 according to the modalities of the present disclosure. It may be desirable that the UE 802 does not display the 5G icon on the screen for several reasons. For example, the UE may be on a Visited Public Land Mobile Network (VPLMN) (ie roaming network), and the UE is prevented from connecting to the NR network while on the VPLMN. In another example, the UE may be under an MME or AMF that prevents the UE from connecting to the NR network due to charging problems or due to the fact that the MME or AMF does not support the 5G RAN. In Figure 8, the UE can receive an indication of the message ATTACH ACCEPT or TRACKING AREA UPDATE ACCEPT or RESTRICTION ACCEPT. In one example, the indication is an indication bit, RestrictDCNR. If ATTACH / TAU / REG indicates the 5G restriction for that PLMN or tracking area (or registration area), then the UE must not show the 5G icon. Alternatively, such mobility restriction can be signaled by the RRC connection configuration of the LTE cell while the ATTACH, TAU or REG procedure is performed. In response to a determination that the NR network is prevented from connecting to the NR network, the UI reports on the screen that there is no coverage by the NR network.
    [0066] [0066] In another example, the determination to display the 5G icon may include the UE by determining whether the device (for example, LTE cell) that provided the UE with information about the possibility of the UE being within coverage by the NR network supports dual connectivity. Figure 9 illustrates a 900 call flow according to the modalities of the present disclosure.
    [0067] [0067] Although the UE can support dual connectivity, the LTE cell itself may not support dual connectivity. To allow dual connectivity, the LTE cell typically interfaces with and communicates with the NR cell, and it is possible that the LTE cell does not have this functionality. In Figure 9, the LTE cell 904 can transmit a SIB including an indication of whether the LTE cell can support dual connectivity (e.g., LTE-NR dual connectivity capability). In one example, an existing SIB or a new SIB may include the list of NR frequencies with an indication of the possibility that such dual connectivity is supported by the LTE cell. If the LTE cell supports dual connectivity, then the UE 902 can display the 5G icon on the screen. If the LTE cell does not support dual connectivity, then the UE 902 is not able to be in dual connectivity mode and connect to both the LTE network and the NR network. In this example, the user may be confused if they see the 5G icon on the UE screen. In response to a determination that the device does not support dual connectivity, the UE 902 reports on the screen that there is no coverage over the NR network.
    [0068] [0068] Figure 10 illustrates a flow of calls 1000 according to the modalities of the present disclosure. If the UE 1002 is connected to the NR network, the UE is also connected to the LTE network. If the LTE network has a problem, such as a radio link failure (RLF) while the UE is connected to the LTE network or is out of service (0OS) while the UE is in idle mode, the UE 1002 may be unable to connect to the NR network. The NR network relies on a healthy LTE link to configure the RRC connection before the UE can have dual connectivity and transmit data on the NR network.
    [0069] [0069] In one example, determining whether to display the 5G icon may include the UE 1002, determining whether the LTE network includes an RLF while the UE is in connected mode (for example, connected to the LTE network and the NR network or connected to the LTE network, but not to the NR network). In response to a determination that the LTE network includes the RLF, the UE 1002 reports on the screen that there is no coverage by the NR network. In another example, determining whether to display the 5G icon may include determining the UE 1002 if the LTE network is OOS while the UE is in idle mode. In response to the detection that the LTE network is OOS, the UE 1002 reports on the screen that there is no coverage by the NR network. Consequently, if the UE 1002 detects that the LTE network has an RLF while the UE is in connected mode or that the LTE network is OOS while the UE is in idle mode, then the UE does not display the 5G icon, even if the UE has a healthy link with the NR cell.
