Generally, a method, which may be performed by a user equipment (UE), includes detecting a trigger event of an emergency network access procedure. The method further includes sending a first message to the base station in response to detecting the trigger event, the first message including a request for using one or more licensed frequency bands to communicate via a wireless in-vehicle network (wIVN). The method also includes receiving a second message from the base station, the second message permitting use of the one or more licensed frequency bands to communicate via the wIVN.

Description

[0001] This application is a divisional application of a patent application with the filing date of May 29, 2020, entitled “Permitted wireless vehicle network access based on emergency network access control” and application number 202080100455.4. Technical Field

[0002] Aspects of the present disclosure relate to wireless communications, and more particularly, aspects of the present disclosure relate to techniques for granting wireless in-vehicle network access based on emergency network access control. Background Art

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access systems include 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, to name a few.

[0004] These multiple access technologies have been adopted by various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a municipal, national, regional, and even global level. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is a collection of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband network access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards that use OFDMA with cyclic prefix (CP) on the downlink (DL) and on the uplink (UL). For these purposes, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0005] As the demand for mobile broadband access continues to increase, there is a need for further improvements in NR and LTE technologies. Preferably, these improvements should be applicable to other multi-access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0027] Various aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for using wireless in-vehicle network access using a licensed frequency band during an emergency network access procedure. Although certain aspects are discussed with respect to wireless in-vehicle network access, such aspects may be used for other wireless device network access using a licensed frequency band and / or for other access procedures during an emergency network access procedure.

[0028] In certain aspects, for accidents involving vehicles, certain regulations may require that a minimum data set (MSD) be sent to a public safety answering point (PSAP) via an emergency network access (e.g., eCall) process. Examples of PSAPs may include, but are not limited to, call centers where emergency calls, such as those from the police, fire department, and / or ambulance, may be received. The MSD may include certain information related to the vehicle, such as vehicle type information, vehicle identification number (VIN), fuel / propulsion type, current location of the vehicle, one or more previous locations of the vehicle, an estimated number of vehicle occupants, etc.

[0029] The MSD may be sent to the PSAP via a communication device (e.g., a modem) that is communicatively coupled to one or more sensors of a vehicle. Examples of sensors may include, but are not limited to, vehicle seat sensors, vehicle body sensors, a global positioning system of a vehicle, an engine control unit of a vehicle, and / or other units of a vehicle that are configured to capture, measure, and / or send information related to the vehicle. Some MSDs in the MSD may include information from one or more sensors of the vehicle. Examples of such information may include, but are not limited to, fuel / propulsion type, current position of the vehicle, one or more previous positions of the vehicle, vehicle direction, estimated number of vehicle occupants, etc. Information from the sensors may be sent to the communication device via a wired vehicle-mounted network (IVN).

[0030] However, when a vehicle is involved in an accident, the communication lines of the IVN connecting one or more sensors to the communication device may be damaged, and vehicle-related information from the sensors may not be sent to the communication device, and the communication device may not be able to successfully provide the MSD to the PSAP via the emergency network access process. This may cause delays in the PSAP dispatching needed help (e.g., first responders).

[0031] Therefore, certain aspects of the present disclosure provide various techniques for the following operations: for example, when a vehicle has an accident, data related to the MSD is successfully sent from one or more sensors of the vehicle to a communication device coupled to a communication ground, and the MSD is sent from the communication device to a PSAP. In certain aspects, the technology for successfully sending data related to the MSD from one or more sensors of the vehicle to a communication device coupled to a communication ground can be based on the following items: when the vehicle is involved in an accident, one or more sensors are configured to communicate with the communication device via a wireless in-vehicle network (wIVN) using one or more licensed frequency bands. One or more licensed frequency bands can be mobile spectrum bands, which are part of the licensed spectrum allocated to a mobile network operator. Using licensed frequency bands when sending information related to the MSD from one or more sensors of the vehicle to a communication device via wIVN can also reduce interference when sending data, while also meeting various reliability requirements for sending MSD related information from sensors to a communication device. In certain aspects, based on certain regulations, when an emergency network access process (e.g., eCall) is initiated, all other communications within the vehicle will be disabled. In some aspects, when the wIVN is configured to operate using a licensed band, it can be configured to operate using one or more licensed bands that do not interfere with emergency network access and may not be subject to regulations. In the wIVN, sensors can communicate wirelessly directly with communication devices and / or other sensors, for example, without the need to communicate via a base station.

[0032] The following description provides an example of a permitted wireless vehicle network access based on emergency network access control in a communication system, without limiting the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various processes or components may be omitted, replaced or added to each example as appropriate. For example, the method described may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, the features described with respect to some examples may be combined into some other examples. For example, a device may be implemented or a method may be implemented using any number of aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims. The word "exemplary" is used herein to mean "used as an example, instance or illustration". Any aspect described as "exemplary" herein may not necessarily be interpreted as being preferred or having advantages over other aspects.

[0033] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as a radio technology, an air interface, etc. Frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, a subband, etc. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs.

[0034] The technology described herein can be used for various wireless networks and radio technologies. Although various aspects herein may be described using terms commonly associated with 3G, 4G and / or new radio (e.g., 5G NR) wireless technologies, various aspects of the present disclosure may be applied to other band-based communication systems.

[0035] NR access can support various wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80 MHz or higher), millimeter wave (mmW) targeting high carrier frequency (e.g., 25 GHz to 53 GHz or higher), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical services targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet their respective quality of service (QoS) requirements. In addition, these services can coexist in the same subframe. NR supports beamforming, and the beam direction can be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in DL can support up to 8 transmit antennas, with multi-layer DL transmission up to 8 streams and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE can be supported. Aggregation of multiple units with up to 8 service units can be supported.

[0036] Figure 1 An example wireless communication network 100 is shown in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a NR system (e.g., a 5G NR network). Figure 1 As shown, wireless communication network 100 may be in communication with a core network 132. Core network 132 may be in communication with one or more base stations (BSs) 110 and / or user equipment (UE) 120 via one or more interfaces.

[0037] According to certain aspects, BS 110 and UE 120 may be configured to send data, including but not limited to system information, MSD, etc. Figure 1As shown, according to various aspects of the present disclosure, BS110a includes a licensed band manager 112, which can be configured to grant and / or authorize requests for access to licensed bands. According to various aspects of the present disclosure, UE 120a includes an emergency network access manager 122, which can be configured to request access to licensed bands for use in wIVN and send an MSD to a PSAP.

[0038] In some aspects, UE 120a can be configured to communicate with one or more sensors of the vehicle via wIVN. In some aspects, when a trigger for emergency network access (e.g., eCall) is not detected, UE 120a and one or more sensors of the vehicle can communicate directly with each other. For example, when a trigger for emergency network access is not detected, UE 120a and one or more sensors of the vehicle can communicate directly with each other via wIVN using Bluetooth, WiFi Direct and other direct communication technologies, as well as frequency bands of unlicensed spectrum that do not require communication via BS110. However, in some aspects, based on regulations, such communications on unlicensed spectrum may not be allowed when the emergency network access process is initiated.

[0039] like Figure 1 As shown, the wireless communication network 100 may include multiple BSs 110a-z (each BS is also referred to as BS 110 or collectively referred to as BS 110 in this document) and other network entities. BS 110 can provide communication coverage for a specific geographic area (sometimes referred to as a "cell"), which can be stationary or can move according to the location of the mobile BS 110. In some examples, BS 110 can use any suitable transmission network to connect to each other and / or one or more other BSs or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (e.g., direct physical connection, wireless connection, virtual network, etc.). Figure 1 In the example shown, BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. For femto cells 102y and 102z, BSs 110y and BSs 110z may be femto BSs, respectively. A base station may support one or more cells.

[0040] BS110 communicates with UEs 120a-y (each UE 120 is also referred to as UE 120 individually or collectively as UE 120 herein) in the wireless communication network 100. UEs 120 (e.g., 120x, 120y, etc.) may be dispersed in the wireless communication network 100, and each UE 120 may be stationary or mobile. The wireless communication network 100 may also include a relay station (e.g., relay station 110r), also referred to as a repeater, etc., which receives transmissions of data and / or other information from an upstream station (e.g., BS110a or UE 120r) and sends transmissions of data and / or other information to a downstream station (e.g., UE 120 or BS110), or relays transmissions between UEs 120 to facilitate communication between devices.

[0041] The network controller 130 may communicate with a set of BSs 110 and provide coordination and control (e.g., via a backhaul) for these BSs 110. In various aspects, the network controller 130 may communicate with a core network 132 (e.g., a 5G core network (5GC)), which provides various network functions, such as access and mobility management, session management, user plane functions, policy control functions, authentication server functions, unified data management, application functions, network exposure functions, network repository functions, network slice selection functions, etc.

[0042] Figure 2 Show (for example, Figure 1 1 and 120a in a wireless communication network 100, which may be used to implement aspects of the present disclosure.

[0043] At BS 110a, a transmit processor 220 may receive data from a data source 212 and control information from a controller / processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. A medium access control (MAC)-control element (MAC-CE) is a MAC layer communication structure that may be used for control command exchange between wireless nodes. The MAC-CE may be carried in a shared channel such as a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical sidelink shared channel (PSSCH).

[0044] The processor 220 may process (e.g., encode and symbol map) data and control information, respectively, to obtain data symbols and control symbols. The transmit processor 220 may also generate reference signals, such as for primary synchronization signals (PSS), secondary synchronization signals (SSS), PBCH demodulation reference signals (DMRS), and channel state information reference symbols (CSI-RS). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols (if applicable), and may provide an output symbol stream to a modulator (MOD) 232a-232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 232a-232t may be sent via antennas 234a-234t, respectively.

[0045] At UE 120a, antennas 252a-252r can receive downlink signals from BS110a and can provide received signals to demodulators (DEMODs) in transceivers 254a-254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, down-convert, and digitize) the respective received signals to obtain input samples. Each demodulator can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain received symbols from all demodulators 254a-254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE120a to data sink 260, and provide decoded control information to controller / processor 280.

[0046] On the uplink, at the UE 120a, a transmit processor 264 may receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 280 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for a reference signal (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a-254r in the transceiver (e.g., for SC-FDM, etc.), and transmitted to the BS 110a. At the BS 110a, the uplink signal from the UE 120a may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120a. Receive processor 238 may provide decoded data to a data sink 239 and decoded control information to controller / processor 240 .

[0047] Memory 242 and memory 282 may store data and program codes for BS 110a and UE 120a, respectively.A scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0048] The antenna 252, processors 266, 258, 264 and / or controller / processor 280 of the UE 120a and / or the antenna 234, processors 220, 230, 238 and / or controller / processor 240 of the BS 110a may be used to perform the various techniques and methods described herein. Figure 2 As shown, the controller / processor 240 of the BS 110a has a licensed band manager 241, which may be configured to grant and / or authorize requests for access to a licensed band, in accordance with various aspects described herein. Figure 2 As shown, according to various aspects described herein, the controller / processor 280 of UE 120a has an emergency network access manager 281, which can be configured to request access to a licensed band for use in a wIVN and send an MSD to a PSAP. Although shown at the controller / processor, other components of UE 120a and BS110a can be used to perform the operations described herein.

[0049] NR can utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on the uplink and downlink. NR can support half-duplex operation using time division duplex (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) divide the system bandwidth into multiple orthogonal subcarriers, which are also commonly referred to as tones, frequency bands, etc. Each subcarrier can be modulated with data. Modulation symbols can be sent in the frequency domain using OFDM, and modulation symbols can be sent in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers can depend on the system bandwidth. The minimum resource allocation, called a resource block (RB), can be 12 consecutive subcarriers. The system bandwidth can also be divided into subbands. For example, a subband can cover multiple RBs. NR can support a basic subcarrier spacing (SCS) of 15KHz, and other SCSs (e.g., 30kHz, 60kHz, 120kHz, 240kHz, etc.) can be defined relative to the basic SCS.

[0050] Figure 3 300 is a schematic diagram showing an example of a frame format for NR. The transmission timeline for each of the downlink and uplink can be divided into units of radio frames. Each radio frame can have a predetermined duration (e.g., 10ms) and can be divided into 10 subframes with indices 0 to 9, each subframe 1ms. Each subframe can include a variable number of slots (e.g., 1, 2, 4, 8, 16... slots), depending on the SCS. Each slot can include a variable number of symbol periods (e.g., 7, 12 or 14 symbols), depending on the SCS. An index can be assigned to the symbol period in each slot. A microslot (which can be referred to as a subslot structure) refers to a transmission time interval having a duration less than a slot (e.g., 2, 3 or 4 symbols). Each symbol in a slot can indicate a link direction (e.g., DL, UL or flexible) for data transmission, and the link direction of each subframe can be dynamically switched. The link direction can be based on the slot format. Each slot can include DL / UL data and DL / UL control information.

[0051] In NR, synchronization signal blocks (SSBs) are transmitted. In certain aspects, SSBs may be transmitted in bursts, where each SSB in the burst corresponds to a different beam direction for UE-side beam management (e.g., including beam selection and / or beam refinement). SSBs include PSS, SSS, and two-symbol PBCH. They may be transmitted at fixed time slot locations (such as at Figure 3The SSB is sent in the symbols 0-3 shown in . PSS and SSS can be used by UE for cell search and acquisition. PSS can provide half-frame timing, and SS can provide CP length and frame timing. PSS and SSS can provide cell identification. PBCH carries some basic system information, such as downlink system bandwidth, timing information within the radio frame, SS burst set periodicity, system frame number, etc. SSB can be organized into SS bursts to support beam scanning. Additional system information, such as remaining minimum system information (RMSI), system information block (SIB), other system information (OSI), can be sent on the physical downlink shared channel (PDSCH) in certain subframes. For millimeter waves (mmWave), SSBs can be sent up to sixty-four times, for example, using up to sixty-four different beam directions. Multiple transmissions of SSB are called SS burst sets. SSBs in an SS burst set can be sent in the same frequency region, while SSBs in different SS burst sets can be sent at different frequency regions.

[0052] As described above, when a vehicle is involved in an accident, certain regulations may require that a minimum data set (MSD) be sent to a public safety answering point (PSAP) via an emergency network access (e.g., eCall) process. The MSD can be sent by a communication device (e.g., UE120a), which can be communicatively coupled to one or more sensors and PSAP of the vehicle. Some MSDs in the MSD may include information captured, measured, analyzed and / or recorded by one or more sensors of the vehicle and sent to the communication device from one or more sensors via IVN and / or wIVN. The communication device can be communicatively coupled to one or more sensors via a wired vehicle network (IVN) and / or a wireless vehicle network (wIVN). As described above, the communication device and one or more sensors of the vehicle can be configured to communicate directly with each other via wIVN using direct communication technologies (such as Bluetooth, WiFi Direct and other similar direct communication technologies).

[0053] When a communication device and one or more sensors are communicatively coupled to each other via an IVN, the communication link (e.g., wire) of the IVN that communicatively couples the one or more sensors to the communication device may be damaged during an accident, and information from the one or more sensors may not be sent to the communication device. Similarly, as described above, when a communication device and one or more sensors are communicatively coupled to each other via a wIVN, information from the sensor to the communication device may not be reliably sent via the wIVN due to interference from other devices in the vehicle that may also use unlicensed spectrum to communicate with each other and / or the communication device. In addition, in some aspects, when an emergency network access process is initiated in certain areas, such communications may not be allowed via unlicensed spectrum. Therefore, such wireless transmission of information from one or more sensors to the communication device may not meet some reliability requirements of regulations requiring the MSD to be transmitted to the PSAP.

[0054] Therefore, what are needed are techniques and apparatus for transmitting certain MSD-related information from one or more sensors of a vehicle to a communication device such that the transmission meets regulatory reliability and performance requirements.

[0055] Example of allowing wireless vehicle network access based on emergency network access control

[0056] Aspects of the present disclosure provide for communication between one or more sensors of a vehicle and a communication device via wIVN using one or more licensed frequency bands.

[0057] Figure 4 A call flow diagram of example operations for sending an MSD upon detecting a trigger of an emergency network access event is shown. The diagram shows transactions between one or more sensors 420 of a vehicle, a UE 430, an NG-RAN 440, a core network 450, and a PSAP 460. Figure 4 In the example shown, UE 430 can be used as described above with reference to Figure 1 , 2 3 and 3. In some aspects, the NG-RAN 440 may be similar to the UE 120a described above. Figure 1 , 2and BS110a described in 3. In some aspects, the NG-RAN 440 may be a plurality of distributed units (DUs) (e.g., edge units (EUs), edge nodes (ENs), radio heads (RHs), smart radio heads (SRHs), transmit receive points (TRPs), etc.) in communication with a plurality of central units (CUs) (e.g., central nodes (CNs), access node controllers (ANCs), etc.), wherein a collection of one or more distributed units in communication with the central unit may define an access node (e.g., new radio base station (NR BS), new radio node-B (NR NB), network node, 5G NB, gNB, etc.). The NG-RAN 440 may communicate with the UE 430 on a downlink channel (e.g., for transmission from a base station or to a UE) and an uplink channel (e.g., for transmission from a UE to a base station or a distributed unit).

[0058] As described above, examples of sensors 420 may include, but are not limited to, vehicle seat sensors, body sensors, a vehicle's global positioning system, a vehicle's engine control unit, and / or other units of the vehicle configured to capture, measure, analyze, and / or transmit information related to the vehicle.

[0059] exist Figure 4 In the example of , UE 430 is connected to NG-RAN 440. At 402, NG-RAN 440 sends information indicating whether the mobile network supports emergency network access (e.g., eCall) to UE 430. NG-RAN 440 can send such information in a system information block (SIB). For example, NG-RAN 440 can indicate that the network supports emergency network access via a bit or a flag in system information block 1 (SIB1). In some aspects, NG-RAN 440 can send information related to whether the network allows the use of licensed bands for communications in wIVN, the range of licensed bands that can be used for communication via wIVN, other corresponding radio resources and / or other operational parameters (e.g., discontinuous reception (DRX) cycle, scheduling period for using licensed bands, etc.). For example, NG-RAN 440 can send information indicating whether the network allows the use of licensed bands in wIVN in another SIB or via another bit in SIB1. Similarly, the NG-RAN 440 may send information related to the range of licensed frequency bands that may be used for communications in the wIVN, other radio resources, and / or configuration of other operational parameters for emergency network access.

[0060] At 404, the UE 430 sends a message including configuration information to one or more sensors 420 of the vehicle. In some aspects, the UE 430 may send a wake-up signal (WUS) message set to configure and / or enable the sensor 420 to use the wIVN to report and / or provide information to the UE 430. In some aspects, each WUS message may include and / or correspond to a set of configuration information. In some aspects, the UE 430 configures the sensor 420 to receive a set of WUS messages at certain time periods. In some aspects, the configuration information may include, but is not limited to, the range of licensed bands that the sensor 420 can use to communicate with the UE 430 via the wIVN, the scheduling period for using the licensed bands, the DRX cycle, etc. The UE 430 may send a message including configuration information to one or more sensors 420 via IVN or wIVN. In some aspects, when sending configuration information to one or more sensors 420 via wIVN, UE 430 may be configured to send configuration information to one or more sensors 430 using direct communication technology (such as Bluetooth, WiFi Direct, etc.) without communicating via a base station (e.g., NG-RAN 440). In some aspects, when sending configuration information at 404, UE 430 may be configured to utilize communication resources without interfering with communications between other units and / or devices of the vehicle to achieve normal operation of the vehicle. For example, UE 430 may wait before sending configuration information to one or more sensors 420 until sufficient communication resources are available and / or until other higher priority tasks are completed.

[0061] In some aspects, the configuration information may be homogeneous across tracking areas (TAs) and / or public land mobile networks (PLMNs). Therefore, in some aspects, the configuration information of one or more sensors 420 may not need to be updated frequently. In some aspects, the UE 430 and one or more sensors 420 may be pre-configured with various emergency network access configurations to configure operational parameters for using licensed bands via wIVN. Based on the location of the vehicle, one or more sensors 420 and the UE 430 may be configured to communicate via wIVN using a licensed band using one of the pre-configured emergency network access configurations.

[0062] At 406, UE 430 may detect a triggering event for emergency network access. As described above, the triggering event for emergency network access may be that the vehicle is involved in an accident. At 408, UE 430 sends a message to NG-RAN 440 requesting the use of one or more licensed frequency bands to communicate with one or more sensors via wIVN. The message may indicate one or more licensed frequency bands that can be used by wIVN and other configuration information of radio resources. Examples of configuration information of radio resources include, but are not limited to, time resources, frequency resources, operating modes, time periods for operation completion, and the like. Examples of operating modes may include, but are not limited to, wIVN network management, data exchange on wIVN (e.g., sending information from one or more sensors 420 to UE 430), and the like.

[0063] In some aspects, the one or more licensed bands indicated in the request of the UE 430 may be based on the range of the licensed bands and other configuration information indicated in one or more SIBs received from the NG-RAN 440. In some aspects, the one or more licensed bands indicated in the request of the UE 430 may be based on the range of the licensed bands and other configuration information indicated in a predetermined emergency network access configuration selected by the UE 430 based on the location of the vehicle. In some aspects, if the UE 430 is in idle mode, the message sent by the UE 430 to the NG-RAN 440 may be a radio resource control (RRC) connection request message. In some aspects, if the UE 430 is in connected mode, the message sent by the UE 430 to the NG-RAN 440 may be a dedicated RRC message (e.g., a sidelink UE information (SLUEinfo) message, a UE assistance information message, etc.).

[0064] At 410, the NG-RAN 440 grants authorization to use the requested licensed band and corresponding radio resources to communicate between the UE 430 and one or more sensors 420 via the wIVN. The NG-RAN 440 may be configured to determine the duration of the licensed band to be used for communication via the wIVN based on the state, mode, and / or information of the UE. For example, if the UE is already in connected mode, and / or if the NG-RAN 440 already has context information of the UE 430 (e.g., whether the UE 430 is authorized, an identification number of the UE 430, etc.), the NG-RAN 440 may determine that the UE 430 meets a certain trust level, and grant a longer duration to use the licensed band and / or other radio resources for communication via the wIVN compared to a case where the UE 430 is in idle mode and / or the NG-RAN 430 does not have context information of the UE 430.

[0065] At 412, UE 430 may send a message to one or more sensors 420 indicating that one or more sensors communicate with UE 430 via wIVN using one or more licensed bands indicated in the message. In some aspects, the message may be a wake-up signal (WUS) message. In some aspects, one or more sensors 420 may be configured to periodically receive and / or poll WUS messages at predetermined time intervals. In some aspects, UE 430 may be configured to set the time interval at 404 as part of the configuration information sent to one or more sensors 420.

[0066] Returning to 412, in some aspects, the message sent by the UE 430 to the one or more sensors 420 may indicate one or more licensed bands and corresponding resources authorized by the NG-RAN 440 for communication via the wIVN. In some aspects, the message sent by the UE 430 to the one or more sensors 420 may indicate a configuration index value, and the one or more sensors 420 may be configured to select a corresponding emergency network access configuration based on the configuration index value in the message.

[0067] At 414, one or more sensors 420 may use the configuration of one or more licensed frequency bands and radio resources as indicated in the message from UE 430 at 412 to send information related to the vehicle to UE 430, such as the fuel / propulsion type of the vehicle, the current position of the vehicle, one or more previous positions of the vehicle, the direction of the vehicle, and / or the estimated number of vehicle occupants. At 416, UE 430 completes the emergency network access process by sending MSD information (which includes information received from sensor 420) to PSAP 460. In some aspects, UE 430 may establish an IP Multimedia Subsystem (IMS) call session with PSAP 460 via NG-RAN 440 and core network 450, and UE 430 may send the MSD to PSAP 460 by embedding the MSD in the IMS call session establishment process.

[0068] In some aspects, NG-RAN 440 may be configured to store vehicle identification information and / or UE430 identification information at 408, and the data may be attached and / or attached to charging record data for use by mobile network operators. In some aspects, charging record data may include vehicle identification information, UE 430 identification information, and one or more licensed bands that are allowed to be accessed. NG-RAN 440 may be configured to send charging records to mobile network operators so that mobile network operators can charge users of UE 430 and / or vehicles for using licensed bands. In some aspects, mobile NG-RAN 440 may embed indicators about the following items in call setup to PSAP: licensed bands and other radio resources granted for wIVN are being used, and additional corresponding charges may be applied to users of vehicles and / or UE 430. In some aspects, mobile network operators may provide charging records to entities (e.g., government entities, regulatory agencies, etc.) as proof of compliance with regulations, or receive additional spectrum as a reward, etc.

[0074] In some aspects, the UE receives a system information block (SIB) message from a base station, the SIB message indicating that the base station supports an emergency network access procedure. In some aspects, the SIB message or accompanying SIB message received by the UE from the base station indicates the configuration of a set of radio resources for communication via wIVN. In some aspects, the UE configures one or more sensors to communicate with the UE via wIVN using one or more licensed bands based on the SIB message. In some aspects, the UE configures one or more sensors via wIVN. In some aspects, the UE configures one or more sensors via one or more wired connections (e.g., via IVN).

[0093] The techniques described herein may be used for various wireless communication technologies, such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), Advanced LTE (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, and the like. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA networks may implement radio technologies such as NR (e.g., 5G RA), 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 E-UTRA are part of Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). NR is an emerging wireless communication technology under development.

[0094] In 3GPP, the term "cell" may refer to the coverage area of ​​a Node B (NB) and / or a NB subsystem serving the coverage area, depending on the context in which the term is used. In NR systems, the terms "cell" and BS, next generation Node B (gNB or gNodeB), access point (AP), distributed unit (DU), carrier or transmit receive point (TRP) may be used interchangeably. A BS may provide communication coverage for a macro cell, a pico cell, a femto cell and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by a UE with an association with a femto cell (e.g., a UE in a closed subscriber group (CSG), a UE for a user in a residence, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be called a femto BS or a home BS.

[0095] UE may also be referred to as a mobile station, a terminal, an access terminal, a user unit, a station, a customer premises equipment (CPE), a cellular phone, a smart phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a home appliance, a medical device or medical equipment, a biometric sensor / device, a wearable device (such as a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music device, a video device, a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless medium or a wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired communication link or a wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.

[0096] In some examples, access to the air interface can be scheduled. The entity that performs scheduling (e.g., BS) allocates resources for communication between some or all devices and equipment within its service area or cell. The entity that performs scheduling can be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize resources allocated by the entity that performs scheduling. The base station is not the only entity that can act as an entity that performs scheduling. In some examples, UE can act as an entity that performs scheduling, and resources can be scheduled for one or more subordinate entities (e.g., one or more other UEs), and other UEs can utilize resources for wireless communication scheduled by UE. In some examples, UE can act as an entity that performs scheduling in a peer-to-peer (P2P) network and / or a mesh network. In the mesh network example, in addition to communicating with the entity that performs scheduling, UEs can also communicate directly with each other.

[0097] The methods disclosed herein include one or more steps or actions for implementing the methods. The method steps and / or actions may be interchangeable without departing from the scope of the claims. In other words, unless a specific order of steps or actions is specified, the order of specific steps and / or actions and / or the use of specific steps and / or actions may be modified without departing from the scope of the claims.

[0098] As used herein, a phrase referring to "at least one of" a list of items refers to any combination of those items, including single members. For example, "at least one of a, b, or c" is intended to cover: a, b, c, ab, ac, bc, and abc, as well as any combination of the same elements having multiples (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc, and ccc or any other arrangement of a, b, and c).

[0100] The foregoing description is provided so that any technician in the field can implement the various aspects described herein. Various modifications to these aspects will be obvious to those skilled in the art, and the general principles defined herein can be applied to other aspects. Therefore, the present claims are not intended to be limited to the various aspects shown herein, but to conform to the full scope consistent with the content expressed by the claims, wherein unless explicitly stated so, the reference to the singular element is not intended to mean "one and only one", but "one or more". Unless explicitly stated otherwise, the term "some" refers to one or more. All structural and functional equivalents of the elements of the various aspects described in the present disclosure, known to or later known to a person of ordinary skill in the art, are explicitly incorporated herein by reference, and are intended to be included by the claims. In addition, there is no content in the content disclosed herein that is intended to be dedicated to the public, regardless of whether such disclosure is explicitly recorded in the claims. No claim element is to be interpreted according to 35 U.S.C. § 112 (f), unless the element is explicitly recorded using the phrase "unit for...", or in the case of a method claim, the element is recorded using the phrase "step for...".

[0101] The various operations of the method described above can be performed by any suitable unit capable of performing the corresponding functions. The unit may include various hardware components and / or software components and / or hardware modules and / or software modules, including but not limited to circuits, application specific integrated circuits (ASICs) or processors. Generally, where there are operations shown in the figure, these operations may have corresponding counterpart functional module components with similar numbers.

[0102] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or executed using a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic devices, discrete hardware components, or any combination thereof, designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in an alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, such as 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.

[0103] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. The bus may include any number of interconnecting buses and bridges depending on the specific application and overall design constraints of the processing system. The bus may link together various circuits including a processor, a machine-readable medium, and a bus interface. The bus interface may be used to connect a network adapter and other things to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In a user terminal (see Figure 1 ), a user interface (e.g., keyboard, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and will not be described any further. The processor may be implemented using one or more general purpose processors and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits that can execute software. Those skilled in the art will recognize how to best implement the described functionality for the processing system depending on the specific application and the overall design constraints imposed on the entire system.

[0104] If implemented in software, the function may be stored on or sent through a computer-readable medium as one or more instructions or codes. Whether referred to as software, firmware, middleware, microcode, hardware description language or other, software should be broadly interpreted as meaning instructions, data or any combination thereof. Computer-readable media include both computer storage media and communication media, and the communication media include any media that facilitates the transmission of computer programs from one place to another. The processor may be responsible for managing the bus and general processing, including the execution of software modules stored on the machine-readable storage medium. The computer-readable storage medium may be coupled to the processor so that the processor can read information from the storage medium and write information to the storage medium. In an alternative manner, the storage medium may be indispensable to the processor. For example, the machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium having instructions stored thereon separated from the wireless node, wherein the owner may be accessed by the processor through a bus interface. Alternatively, or in addition, the machine-readable medium or any part thereof may be integrated into the processor, such as the case may be with a cache and / or a general register file. For example, examples of machine-readable storage media may include RAM (random access memory), flash memory, ROM (read-only memory), PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. Machine-readable media may be embodied in a computer program product.

[0105] A software module may include a single instruction or many instructions, and may be distributed over several different code segments, among different programs, and across multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that, when executed by a device (such as a processor), cause a processing system to perform various functions. A software module may include a sending module and a receiving module. Each software module may exist in a single storage device, or may be distributed across multiple storage devices. For example, a software module may be loaded from a hard drive into a RAM when a triggering event occurs. During execution of the software module, the processor may load some of the instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When referring to the functions of the software modules below, it will be understood that such functions are implemented by the processor when executing instructions from the software modules.

[0106] Moreover, any connection may properly be termed a computer-readable medium. For example, if the software is transmitted from a website, server or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies (such as infrared (IR), radio and microwave), then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies (such as infrared, radio and microwave) are included in the definition of medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Optical disks, where magnetic disks typically reproduce data magnetically, and optical disks use lasers to reproduce data optically. Thus, in some aspects, computer-readable media may include non-transitory computer-readable media (e.g., tangible media). Additionally, for other aspects, computer-readable media may include transitory computer-readable media (e.g., signals). Combinations of the above should also be included within the scope of computer-readable media.

[0107] Thus, certain aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having instructions stored (and / or encoded) thereon, the instructions being executable by one or more processors to perform the operations described herein. For example, a computer program product for performing the operations described herein and in Figure 5 , Figure 6 , Figure 7 and / or Figure 8 The operations shown in the instructions.

[0108] Further, it should be appreciated that the modules and / or other appropriate units for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by, for example, applicable user terminals and / or base stations. For example, such a device can be coupled to a server to facilitate the transmission of the units for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage unit (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or a floppy disk, etc.), so that the user terminal and / or base station can obtain the various methods when the storage unit is coupled to the device or provided to the device. In addition, any other suitable technology for providing the methods and techniques described herein to the device can be utilized.

[0109] It is to be understood that the claims are not limited to the precise configuration and components shown above. Various modifications, changes and variations may be made in the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
