Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] The present application claims priority to U.S. patent application Ser. No. 16 / 889,469, filed on Jun. 1, 2020, and entitled “METHODS AND APPARATUS FOR PARKING LOT EXIT MANAGEMENT USING V2X,” which is assigned to the assignee of the present application and is hereby expressly incorporated herein by reference for all purposes. Background Art

[0003] Aspects of the present disclosure relate generally to wireless communications, and more particularly to apparatus and methods for parking lot exit management using V2X.

[0004] Wireless communication networks are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and single-carrier frequency division multiple access (SC-FDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different wireless devices to communicate at municipal, national, regional, and even global levels. For example, the fifth generation (5G) wireless communication technology, which may be referred to as New Radio (NR), is envisioned to expand and support diverse usage scenarios and applications relative to current mobile network generations. On the one hand, 5G communication technology may include: enhanced mobile broadband that addresses human-centric use cases for accessing multimedia content, services, and data; ultra-reliable low-latency communications (URLLC) with certain specifications for latency and reliability; and massive machine-type communications, which may allow for very large numbers of connected devices and the transmission of relatively small amounts of non-delay-sensitive information. However, as the demand for mobile broadband access continues to increase, further improvements to NR communication technology and beyond can be expected.

[0006] In a vehicle-to-everything (V2X) network, multiple vehicles attempting to exit a parking area within a time frame (e.g., after a sporting event, end of the school day, shift change, etc.) may encounter congestion. Determining the order and / or optimal exit location to exit a parking area may be cumbersome for a driver and / or autonomous vehicle. Therefore, improvements are desired to fully utilize the V2X network to manage traffic and / or reduce congestion. Summary of the invention

[0025] The specific embodiments described below in conjunction with the accompanying drawings are intended to describe various configurations and are not intended to represent that only the configurations of these concepts described herein can be put into practice. The specific embodiments include specific details for providing a thorough understanding of the purpose of various concepts. However, it is obvious to those skilled in the art that these concepts can be put into practice without these specific details. In some instances, well-known structures and components are shown in the form of block diagrams to avoid blurring these concepts.

[0026] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0027] For example, an element or any part of an element or any combination of elements may be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout the present disclosure. One or more processors in a processing system may execute software. Whether referred to as software, firmware, middleware, microcode, hardware description language, or other, software should be broadly understood to mean instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, processes, functions, etc.

[0028] Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on a computer-readable medium, or encoded as one or more instructions or codes on a computer-readable medium. Computer-readable media include computer storage media. Storage media may be any available media that can be accessed by a computer. As an example and not limitation, such computer-readable media may include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of the aforementioned types of computer-readable media, or any other media that can be used to store computer executable code in the form of instructions or data structures and can be accessed by a computer.

[0029] In one implementation, the RSU may communicate with the vehicle via V2X communication. The RSU may receive one or more departure requests from the vehicle in the parking area. The RSU may determine a departure order based on at least one of the order in which the one or more departure requests are received, vehicle information, vehicle proximity to an exit, or other criteria. The RSU may send the departure order to the vehicle.

[0030] Figure 11 is a diagram showing an example of a wireless communication system and an access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes at least one BS 105, a UE 110, an evolved packet core (EPC) 160, and a 5G core (5GC) 190. The BS 105 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). The macro cell includes a base station. The small cell includes a femto cell, a pico cell, and a micro cell. In one implementation, the UE 110 may include a communication component 222 configured to communicate with the BS 105 via a cellular network, a Wi-Fi network, or other wireless and wired networks. In some implementations, the communication component 222 may be implemented using hardware, software, or a combination of hardware and software. In some implementations, the BS 105 may include a communication component 322 configured to communicate with the UE 110. The BS 105 may include a determination component 324 configured to determine the departure order of multiple vehicles. In some implementations, the communication component 322 and / or the determination component 324 can be implemented using hardware, software, or a combination of hardware and software.

[0031] The BS 105 configured for 4G Long Term Evolution (LTE) (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 via a backhaul link interface 132 (e.g., S1, X2, Internet Protocol (IP), or a flexible interface). The BS 105 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) can interface with the 5GC 190 via a backhaul link interface 134 (e.g., S1, X2, Internet Protocol (IP), or a flexible interface). Among other functions, BS 105 can perform one or more of the following functions: transmission of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and device tracking, RAN information management (RIM), paging, positioning, and delivery of warning messages. BS 105 can communicate with each other directly or indirectly (e.g., through EPC 160 or 5GC 190) via a backhaul link interface 134. Backhaul links 132, 134 can be wired or wireless.

[0032] BS105 can communicate with UE 110 wirelessly. Each of BS105 can provide communication coverage for corresponding geographic coverage area 130. There can be overlapping geographic coverage areas 130. For example, small cell 105' can have coverage area 130' overlapping with coverage area 130 of one or more macro BS105. A network including both small cell and macro cell can be called a heterogeneous network. Heterogeneous network can also include home evolved Node B (eNB) (HeNB), which can provide services to a restricted group called closed subscriber group (CSG). The communication link 120 between BS105 and UE 110 can include uplink (UL) (also called reverse link) transmission from UE 110 to BS105 and / or downlink (DL) (also called forward link) transmission from BS105 to UE 110. Communication link 120 can use multiple input multiple output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link can be through one or more carriers. BS 105 / UE 110 may use spectrum with up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier, which is allocated in up to Y total bandwidths for transmission in each direction. x MHz (x component carriers). The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric for DL ​​and UL (e.g., more or fewer carriers may be allocated to DL compared to UL). The component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell), and the secondary component carrier may be referred to as a secondary cell (SCell).

[0033] Certain UEs 110 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0034] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 in the 5 GHz unlicensed spectrum via a communication link 154. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) before communicating to determine whether the channel is available.

[0035] The small cell base station 105' can operate in licensed and / or unlicensed spectrum. When operating in the unlicensed spectrum, the small cell 105' can adopt NR and use the same 5 GHz unlicensed spectrum used by the Wi-Fi AP 150. The small cell 105' adopting NR in the unlicensed spectrum can expand the coverage of the access network and / or increase the capacity of the access network.

[0036] BS 105, whether a small cell 105' or a large cell (e.g., a macro base station), may include an eNB, a gNodeB (gNB), or other types of base stations. Some base stations, such as gNB 180, may operate in the traditional sub-6 GHz spectrum, in millimeter wave (mmW) frequencies, and / or near-mmW frequencies for communicating with UE 110. When gNB 180 operates in mmW or near-mmW frequencies, gNB 180 may be referred to as a mmW base station. Extremely high frequency (EHF) is part of the radio frequency (RF) in the electromagnetic spectrum. EHF has a range of 30 GHz to 300 GHz and a wavelength between 1 mm and 10 mm. Radio waves in this band may be referred to as millimeter waves. Near mmW may extend down to a frequency of 3 GHz with a wavelength of 100 mm. The super high frequency (SHF) band extends between 3 GHz and 30 GHz and is also referred to as centimeter waves. Communications using mmW / near-mmW radio frequency bands have extremely high path loss and short range. The mmW base station 180 may use beamforming 182 with the UE 110 to compensate for path loss and short range.

[0037] The EPC 160 may include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 110 and the EPC 160. Typically, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a packet switched (PS) streaming service, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 105 belonging to a multicast broadcast single frequency network (MBSFN) area that broadcasts specific services, and may be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0038] 5GC 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196. AMF 192 is a control node that handles signaling between UE 110 and 5GC 190. Typically, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, intranet, IP multimedia subsystem (IMS), PS streaming services, and / or other IP services.

[0039] BS 105 may also be referred to as gNB, Node B, evolved Node B (eNB), access point, base transceiver station, radio base station, access point, access node, radio transceiver, NodeB, eNodeB (eNB), gNB, home NodeB, home eNodeB, relay, transceiver function, basic service set (BSS), extended service set (ESS), transmit receive point (TRP), or some other suitable term. BS 105 provides an access point to EPC 160 or 5GC 190 for UE 110. Examples of UE 110 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablet computers, smart devices, wearable devices, vehicles, electronic meters, gas pumps, large or small kitchen appliances, healthcare equipment, implants, sensors / actuators, displays, or any other similarly functional device. Some of the UEs 110 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.) UE 110 may also be referred to as a station, 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 client, or some other suitable terminology.

[0040] refer to Figure 2 , one example of an implementation of the UE 110 may include a modem 220 having a communication component 222. In one implementation, the UE 110 may include a communication component 222 configured to communicate with the BS 105 via a cellular network, a Wi-Fi network, or other wireless and wired networks.

[0041] In some implementations, the UE 110 may include various components, including components such as one or more processors 212 and memory 216 and transceiver 202 communicating via one or more buses 244, which may operate in conjunction with a modem 220 and a communication component 222 to enable one or more of the functions described herein with respect to communicating with the BS 105. In addition, the one or more processors 212, the modem 220, the memory 216, the transceiver 202, the RF front end 288, and the one or more antennas 265 may be configured to support voice and / or data calls (simultaneously or non-simultaneously) in one or more radio access technologies. The one or more antennas 265 may include one or more antennas, antenna elements, and / or antenna arrays.

[0042] In one aspect, the one or more processors 212 may include a modem 220 using one or more modem processors. Various functions related to the communication component 222 may be included in the modem 220 and / or the processor 212, and in one aspect, may be performed by a single processor, while in other aspects, different functions of the functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 212 may include any one or any combination of a modem processor or a baseband processor or a digital signal processor or a transmit processor or a receive device processor or a transceiver processor associated with the transceiver 202. Additionally, the modem 220 may configure the UE 110 as well as the processor 212. In other aspects, some of the features of the one or more processors 212 and / or the modem 220 associated with the communication component 222 may be performed by the transceiver 202.

[0043] The memory 216 may be configured to store local versions of the data used and / or the applications 275. Moreover, the memory 216 may be configured to store local versions of one or more of the communication components 222 and / or subcomponents executed by the at least one processor 212. The memory 216 may include any type of computer-readable medium usable by a computer or at least one processor 212, such as random access memory (RAM), read-only memory (ROM), tape, disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, when the UE 110 is operating at least one processor 212 to execute one or more of the communication components 222 and / or subcomponents, the memory 216 may be a non-transitory computer-readable storage medium storing one or more computer-executable codes defining one or more of the communication components 222 and / or subcomponents and / or data associated therewith.

[0044] The transceiver 202 may include at least one receiver 206 and at least one transmitter 208. The receiver 206 may include hardware, firmware, and / or software code executable by a processor for receiving data, the code including instructions and stored in a memory (e.g., a computer-readable medium). The receiver 206 may be, for example, an RF receiving device. In one aspect, the receiver 206 may receive a signal transmitted by at least one BS 105. The transmitter 208 may include hardware, firmware, and / or software code executable by a processor for transmitting data, the code including instructions and stored in a memory (e.g., a computer-readable medium). Suitable examples of the transmitter 208 may include, but are not limited to, an RF transmitter.

[0045] In addition, in an aspect, the UE 110 may include an RF front end 288 that may be operable to communicate with the one or more antennas 265 and the transceiver 202 for receiving and sending radio transmissions, such as wireless communications sent by at least one BS 105 or wireless transmissions sent by the UE 110. The RF front end 288 may be coupled to the one or more antennas 265 and may include one or more low noise amplifiers (LNAs) 290, one or more switches 292, one or more power amplifiers (PAs) 298, and one or more filters 296 for sending and receiving RF signals.

[0046] In one aspect, the LNA 290 can amplify the received signal at a desired output level. In one aspect, each LNA 290 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular LNA 290 and a specified gain value based on a desired gain value for a particular application.

[0047] In addition, for example, one or more PAs 298 can be used by the RF front end 288 to amplify the signal for RF output to a desired output power level. In one aspect, each PA 298 can have a specified minimum and maximum gain value. In one aspect, the RF front end 288 can use one or more switches 292 to select a particular PA 298 and a specified gain value based on a desired gain value for a particular application.

[0048] Also, for example, one or more filters 296 can be used by the RF front end 288 to filter received signals to obtain input RF signals. Similarly, in one aspect, for example, a corresponding filter 296 can be used to filter the output from the corresponding PA 298 to produce an output signal for transmission. In one aspect, each filter 296 can be coupled to a specific LNA 290 and / or PA 298. In one aspect, the RF front end 288 can use one or more switches 292 to select a transmit or receive path using a specified filter 296, LNA 290, and / or PA 298 based on a configuration specified by the transceiver 202 and / or the processor 212.

[0049] As such, transceiver 202 may be configured to transmit and receive wireless signals through one or more antennas 265 via RF front end 288. In one aspect, transceiver may be tuned to operate at a specified frequency so that UE 110 may communicate with, for example, one or more BSs 105 or one or more cells associated with one or more BSs 105. In one aspect, modem 220 may configure transceiver 202 to operate at a specified frequency and power level based on, for example, a UE configuration of UE 110 and a communication protocol used by modem 220.

[0050] On the one hand, modem 220 can be a multi-band multi-mode modem that can process digital data and communicate with transceiver 202 so that digital data is sent and received using transceiver 202. On the one hand, modem 220 can be multi-band and configured to support multiple frequency bands for a specific communication protocol. On the one hand, modem 220 can be multi-mode and configured to support multiple operating networks and communication protocols. On the one hand, modem 220 can control one or more components (e.g., RF front end 288, transceiver 202) of UE 110 to enable the transmission and / or reception of signals from the network based on a specified modem configuration. On the one hand, the modem configuration can be based on the mode of the modem and the frequency band used. On the other hand, the modem configuration can be based on UE configuration information associated with UE 110 provided by the network.

In some implementations, the BS 105 may include a communication component 322 configured to communicate with the UE 110. The BS 105 may include a determination component 324 configured to determine a departure order of the plurality of vehicles.

[0052] In some implementations, the BS 105 may include various components, including components such as one or more processors 312 and memory 316 and a transceiver 302 communicating via one or more buses 344, which may operate in conjunction with a modem 320 and a communication component 322 to enable one or more of the functions described herein with respect to communicating with the UE 110. In addition, the one or more processors 312, modem 320, memory 316, transceiver 302, RF front end 388, and one or more antennas 365 may be configured to support voice and / or data calls (simultaneous or non-simultaneous) in one or more radio access technologies.

[0053] In one aspect, the one or more processors 312 may include a modem 320 using one or more modem processors. Various functions related to the communication component 322 and / or the determination component 324 may be included in the modem 320 and / or the processor 312, and in one aspect, may be performed by a single processor, while in other aspects, different functions in the functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 312 may include any one or any combination of a modem processor or a baseband processor or a digital signal processor or a transmit processor or a receive device processor or a transceiver processor associated with the transceiver 302. Additionally, the modem 320 may configure the BS 105 and the processor 312. In other aspects, some features of the one or more processors 312 and / or the modem 320 associated with the communication component 322 may be performed by the transceiver 302.

[0054] The memory 316 may be configured to store local versions of data and / or applications 375 used herein. Moreover, the memory 316 may be configured to store local versions of one or more of the data and / or communication components 322 and / or determination components 324 and / or subcomponents executed by at least one processor 312 used herein. The memory 316 may include any type of computer-readable medium capable of being used by a computer or at least one processor 312, such as random access memory (RAM), read-only memory (ROM), tape, disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, when the BS 105 is operating at least one processor 312 to execute one or more of the communication components 322 and / or determination components 324 and / or subcomponents, the memory 316 may be a non-transitory computer-readable storage medium storing one or more computer-executable codes defining one or more of the communication components 322 and / or determination components 324 and / or subcomponents and / or data associated therewith.

[0055] The transceiver 302 may include at least one receiver 306 and at least one transmitter 308. The at least one receiver 306 may include hardware, firmware, and / or software code executable by a processor for receiving data, the code including instructions and stored in a memory (e.g., a computer-readable medium). The receiver 306 may be, for example, an RF receiving device. In an aspect, the receiver 306 may receive a signal transmitted by the UE 110. The transmitter 308 may include hardware, firmware, and / or software code executable by a processor for transmitting data, the code including instructions and stored in a memory (e.g., a computer-readable medium). Suitable examples of the transmitter 308 may include, but are not limited to, an RF transmitter.

[0056] In addition, in an aspect, the BS 105 may include an RF front end 388 that may be operable to communicate with the one or more antennas 365 and the transceiver 302 for receiving and sending radio transmissions, such as wireless communications sent by other BSs 105 or wireless transmissions sent by the UE 110. The RF front end 388 may be coupled to the one or more antennas 365 and may include one or more low noise amplifiers (LNAs) 390, one or more switches 392, one or more power amplifiers (PAs) 398, and one or more filters 396 for sending and receiving RF signals.

[0057] In one aspect, the LNA 390 can amplify the received signal to a desired output level. In one aspect, each LNA 390 can have a specified minimum and maximum gain value. In one aspect, the RF front end 388 can use one or more switches 392 to select a specific LNA 390 and a specified gain value based on a desired gain value for a particular application.

[0058] In addition, for example, one or more PAs 398 can be used by the RF front end 388 to amplify the signal for RF output to a desired output power level. In one aspect, each PA 398 can have a specified minimum and maximum gain value. In one aspect, the RF front end 388 can use one or more switches 392 to select a particular PA 398 and a specified gain value based on a desired gain value for a particular application.

[0059] Also, for example, one or more filters 396 can be used by the RF front end 388 to filter received signals to obtain input RF signals. Similarly, in one aspect, for example, a corresponding filter 396 can be used to filter outputs from corresponding PAs 398 to produce output signals for transmission. In one aspect, each filter 396 can be coupled to a specific LNA 390 and / or PA 398. In one aspect, the RF front end 388 can use one or more switches 392 to select a transmit or receive path using a specified filter 396, LNA 390, and / or PA 398 based on a configuration specified by the transceiver 302 and / or the processor 312.

[0060] As such, the transceiver 302 may be configured to transmit and receive wireless signals through one or more antennas 365 via the RF front end 388. In one aspect, the transceiver may be tuned to operate at a specified frequency so that the BS 105 may communicate with, for example, a UE 110 or one or more cells associated with one or more BSs 105. In one aspect, the modem 320 may configure the transceiver 302 to operate at a specified frequency and power level based on, for example, the base station configuration of the BS 105 and the communication protocol used by the modem 320.

[0061] On the one hand, modem 320 can be a multi-band multi-mode modem, which can process digital data and communicate with transceiver 302, so that digital data is sent and received using transceiver 302. On the one hand, modem 320 can be multi-band and configured to support multiple frequency bands for specific communication protocols. On the one hand, modem 320 can be multi-mode and configured to support multiple operating networks and communication protocols. On the one hand, modem 320 can control one or more components (e.g., RF front end 388, transceiver 302) of BS105 to enable the transmission and / or reception of signals from the network based on the specified modem configuration. On the one hand, the modem configuration can be based on the mode of the modem and the frequency band used. On the other hand, the modem configuration can be based on the base station configuration associated with BS105.

[0062] Figure 4 An example of an environment for managing the order of departure of vehicles is shown. In some implementations, reference Figure 1 , the environment 400 may include a parking area 402, such as a parking lot, a parking garage, etc. The parking area 402 may include one or more exits 404. The parking area 402 may include vehicles 420 parked in parking spaces 410 (e.g., 410-a–410-h). For example, a first vehicle 420-a may be parked in a first parking space 410-a, a second vehicle 420-b may be parked in a second parking space 410-b, and so on. The vehicle 420 may include a UE 110. The environment 400 may include a roadside unit (RSU) 430 that communicates with the UE 110 in the vehicle 420. The RSU 430 may be implemented as a BS 105. The parking area 402 may include vehicles with a UE 110 and vehicles without a UE 110.

[0063] In some implementations, the vehicle 420 (or the UE 110 of the vehicle 420) may send a departure request to the RSU 430. Upon receiving the departure request from the vehicle 420, the RSU 430 may determine a departure order associated with the vehicle 420. The RSU 430 may send a departure command (based on the departure order) to the vehicle 420. Upon receiving the departure command from the RSU 430, the vehicle 420 may leave the parking area 402 according to the departure command.

[0064] The RSU 430 may determine the order of departure. In some aspects of the present disclosure, the RSU 430 may determine the order of departure based on the order of departure requests received by the RSU 430. The RSU 430 may determine the order of departure based on the proximity of the vehicle 420 to one or more exits of the parking area 402. The RSU 430 may determine the order of departure based on the size, maneuverability, and / or estimated fuel consumption of the vehicle 420. The RSU 430 may determine the order of departure based on the estimated duration for the vehicle 420 to leave the parking area 402. The RSU 430 may determine the order of departure based on the priority associated with the departure request. An example of a "high priority" departure request may include a first responder vehicle (e.g., ambulance, police, etc.) requesting to leave the parking area 402. In some implementations, the RSU 430 may rely on one or more of the above to determine the order of departure. Other criteria that the RSU 430 may rely on to determine the order of departure include the presence of pedestrians, cyclists, or other road users, proximity to the exit, and vehicle type (buses or other transportation vehicles may be granted priority and / or access to alternative / restricted exits).

[0065] In a first example, a vehicle 420 (including a UE 110 associated with the vehicle 420) may send a departure request to the RSU 430 after an event (e.g., a concert, a sporting event, a convention) (e.g., triggered by starting the engine of the vehicle 420 and / or shifting to reverse or drive gear, or sent by an operator of the vehicle (not shown), the last known location of the vehicle 420 before it was turned off, the current location, a camera sensor of the RSU 430 detecting that the vehicle 420 is located in the parking area 402, an operator action in the vehicle, a remote operator action, detection of other airborne requests to leave the parking area 402, etc.). The RSU 430 may receive departure requests based on the following order: a fourth vehicle 420-d, a sixth vehicle 420-f, a first vehicle 420-a, a seventh vehicle 420-g, an eighth vehicle 420-h, a third vehicle 420-c, a fifth vehicle 420-e, and a second vehicle 420-b. The third vehicle 420-c may be a first responder vehicle (e.g., a police patrol car). The departure request of the third vehicle 420 - c may be a high priority request indicating that the third vehicle 420 - c has been requested to handle an emergency situation (eg, a vehicle accident).

[0066] In one aspect of the present disclosure, the RSU 430 may determine the order of departure based on the priority and order in which the departure requests are received. Thus, the RSU 430 may determine that the third vehicle 420-c will leave the parking area 402 first, followed in sequence by the fourth vehicle 420-d, the sixth vehicle 420-f, the first vehicle 420-a, the seventh vehicle 420-g, the eighth vehicle 420-h, the fifth vehicle 420-e, and the second vehicle 420-b. Other ways of determining the order of departure may also be implemented (examples described below).

[0067] In some aspects of the present disclosure, once the departure order is determined, the RSU 430 may send a departure command to the vehicles 420. The RSU 430 may send a departure command to each of the corresponding vehicles 420 at the respective scheduled departure time. For example, the RSU 430 may estimate that each vehicle needs t exit After determining the exit order, at t=0 (e.g., the time when the RSU 430 starts to send the exit command), the RSU 430 may send a first exit command to the third vehicle 420-c to leave the parking area 402. exit At about t=2·t exit , the RSU 430 may send a third exit command to the sixth vehicle 420-f to leave the parking area 402, and so on.

[0068] In one aspect of the present disclosure, in response to receiving a departure command at a scheduled departure time, vehicle 420 may begin to leave parking area 402. For example, after receiving a first departure command at approximately t=0, third vehicle 420-c may begin to leave parking area 402. At approximately t=t exit After receiving the second exit command, the fourth vehicle 420-d can start to leave the parking area 402, and so on.

[0069] In certain aspects of the present disclosure, the RSU 430 may rely on sensors (not shown), such as vision sensors, proximity sensors, and / or positioning sensors, to determine whether the vehicle that is leaving has begun to leave the parking area or has safely left the parking area 402 before sending the next leaving command to the next vehicle that is scheduled to leave the parking area 402. In some aspects, the RSU 430 may utilize sensors to detect to monitor the presence of pedestrians or other vehicles (other than the vehicle 420) in the parking area 402. In response to detecting a pedestrian (for example), the RSU 430 may issue an updated leaving command to the vehicle 420 (e.g., instructing the vehicle to temporarily suspend leaving due to the pedestrian).

[0070] In some aspects, vehicle 420 can utilize sensors (not shown), such as vision sensors, proximity sensors, and / or positioning sensors, to improve the safety of vehicle 420 when leaving parking area 402. For example, the vehicle can utilize sensors to monitor the presence of pedestrians or other vehicles in parking area 402.

[0071] In one aspect, the UE 110 associated with the vehicle 420 may display the departure command and / or information associated with the departure command to one or more operators of the vehicle 420 (via a display, not shown) or via a display screen of the UE 110, and the one or more operators may operate the vehicle 420 based on the departure command and / or the information associated with the departure command. In another aspect, the UE 110 associated with the vehicle 420 may send the departure command and / or information associated with the departure command to one or more autonomous driving systems associated with the vehicle 420. The one or more autonomous driving systems may operate the vehicle 420 based on the departure command and / or the information associated with the departure command.

[0072] In a second example, a vehicle 420 (including a UE 110 associated with the vehicle 420) may send a departure request to an RSU 430 at the end of a work shift, work day, or school day. The RSU 430 may receive the departure request from the vehicle 420. The departure request may include vehicle information associated with the corresponding vehicle 420. For example, the departure request from the first vehicle 420-a may include the brand, model, type, estimated gas efficiency, or other vehicle information associated with the first vehicle 420-a. The departure requests from the remaining vehicles 420 may include similar or different vehicle information about the corresponding vehicles 420.

[0073] In one aspect of the present disclosure, the RSU 430 may determine the order of departure based on the vehicle information included in the departure request. For example, the RSU 430 may determine to allow smaller vehicles (e.g., shorter length and / or width, better maneuverability) to leave first to allow larger vehicles (lower maneuverability) to have more room to leave the parking area 402. Alternatively, the RSU 430 may determine to allow less fuel-efficient vehicles to leave first to save fuel. Thus, the RSU 430 may determine that the sixth vehicle 420-f will leave the parking area 402 first, followed in sequence by the first vehicle 420-a, the fifth vehicle 420-e, the fourth vehicle 420-d, the third vehicle 420-c, the second vehicle 420-b, the eighth vehicle 420-h, and the seventh vehicle 420-g.

[0074] In some aspects of the present disclosure, once the departure order is determined, the RSU 430 may send a departure command to the vehicles 420. The RSU 430 may send the scheduled departure time for each of the vehicles 420 to leave the parking area 402 to the vehicles 420 with the departure command. For example, the RSU 430 may estimate that each vehicle needs t exit ' duration to leave the parking area 402. After determining the departure order, at t=0 (e.g., the time when the RSU 430 starts sending departure commands), the RSU 430 may send a departure command. The departure command to the sixth vehicle 420-f (the first vehicle scheduled to leave the parking area 402) may include a departure time of t=0. The departure command to the first vehicle 420-a may include a departure time of t=t exit The departure command to the fifth vehicle 420-e may include t=2·t exit 's departure time, and so on.

[0075] In some aspects, vehicles 420 may begin to leave parking area 402 based on the assigned departure time in the departure command. For example, after receiving the departure command including the scheduled departure time, sixth vehicle 420-f (the first vehicle scheduled to leave parking area 402) may begin to leave parking area 402 at substantially t=0. First vehicle 420-a may begin to leave parking area 402 at substantially t=t exit ' begins to leave the parking area 402. The fifth vehicle 420-e may leave the parking area 402 at approximately t=2·t exit ' starts to leave the parking area 402, and so on.

[0076] In a third example, a vehicle 420 (including a UE 110 associated with the vehicle 420) may send a departure request to an RSU 430. The RSU 430 may receive the departure request from the vehicle 420. The departure request may include identification information associated with the corresponding vehicle 420. For example, the departure request from the first vehicle 420-a may include the brand, model, color, license plate, construction (e.g., "travel kit", chrome wheels, etc.), location of the vehicle, identification marks (e.g., scratches), accessories (e.g., spoiler), vehicle type, or other identification information associated with the first vehicle 420-a. The departure requests from the remaining vehicles 420 may include similar or different identification information about the respective vehicles 420.

[0077] In one aspect of the present disclosure, the RSU 430 may determine the order of departure based on the identification information included in the departure request. For example, the RSU 430 may determine that vehicles closer to the one or more exits 404 are allowed to leave first. Thus, the RSU 430 may determine that the fifth vehicle 420-e will leave the parking area 402 first, followed in sequence by the first vehicle 420-a, the sixth vehicle 420-f, the second vehicle 420-b, the seventh vehicle 420-g, the third vehicle 420-c, the eighth vehicle 420-h, and the fourth vehicle 420-d.

[0078] In some aspects of the present disclosure, once the exit order is determined, the RSU 430 may send an exit command to the vehicles 420. The RSU 430 may send an exit command to the first vehicle scheduled to leave to leave the parking area 402. The RSU 430 may send identification information associated with the vehicle scheduled to leave before each of the remaining vehicles to the remaining vehicles. The exit command may instruct the remaining vehicles to follow the vehicle scheduled to leave before each of the remaining vehicles. For example, the RSU 430 may send a first exit command to the fifth vehicle 420-e to leave the parking area 402. The RSU 430 may send a second exit command including identification information (e.g., color, make, model, accessories, etc.) associated with the fifth vehicle 420-e (e.g., a blue Honda Accord with a black rear wing) to the first vehicle 420-a. In the second exit command, the RSU 430 may instruct the first vehicle 420-a to follow the fifth vehicle 420-e to leave the parking area 402. The RSU 430 may send a message to the sixth vehicle 420-f including the information associated with the first vehicle 420-a (eg, a red Ford F-150). TM In the second departure command, the RSU 430 may indicate to the sixth vehicle 420-f that the sixth vehicle 420-f is dispatched to the “red Ford F-150 TM Truck" (i.e., first vehicle 420-a) then leaves.

[0079] In some aspects, vehicles 420 may begin to leave parking area 402 based on the exit order in the exit command. For example, after receiving the exit command, fifth vehicle 420-e may begin to leave parking area 402. First vehicle 420-a may follow fifth vehicle 420-e to leave parking area 402. Sixth vehicle 420-f may follow first vehicle 420-a to leave parking area 402, and so on.

[0080] In other implementations, different numbers of vehicles, RSUs, and exits in a parking area may be implemented according to aspects of the present disclosure.

[0081] Figure 5An example of a flow chart for parking lot exit management using V2X is shown. In some implementations, reference Figure 5 , flowchart 500 may include vehicle 420 and RSU 430. At 510, vehicle 420 may send a departure request to RSU 430. The departure request may be implemented as one or more messages. The one or more messages may include at least one of the following fields: sequence number, device identifier, timer, vehicle latitude, vehicle longitude, vehicle altitude, owner type, message type, vehicle category, vehicle classification, or priority. At 520, as discussed above, RSU 430 may determine the departure order based on the information in the departure request. At 530, RSU 430 may send a departure command to vehicle 420. The departure command may include one or more messages. The one or more messages may include at least one of the following fields: departure start time, preceding vehicle, or exit location. At 540, vehicle 420 may leave parking area 402 based on the departure command.

[0082] Figure 6 An example of a method for parking lot exit management using V2X performed by an RSU is shown. For example, the method 600 may be performed by one or more of the processor 312, memory 316, application 375, modem 320, transceiver 302, receiver 306, transmitter 308, RF front end 388, communication component 322, and / or determination component 324 and / or one or more other components of the BS 105 in the wireless communication network 100.

[0083] At block 605, method 600 may receive multiple requests to leave a parking area including multiple vehicles from multiple user devices (UEs), wherein each of the multiple UEs is associated with a corresponding vehicle in the multiple vehicles. For example, as described above, the communication component 322, transceiver 302, receiver 306, transmitter 308, RF front end 388, subcomponents of RF front end 388, processor 312, memory 316, modem 320, and / or application 375 of BS105 may receive multiple requests to leave a parking area including multiple vehicles from multiple user devices (UEs), wherein each of the multiple UEs is associated with a corresponding vehicle in the multiple vehicles. RF front end 388 may receive an electrical signal converted from an electromagnetic signal. RF front end 388 may filter and / or amplify the electrical signal. Transceiver 302 or receiver 306 may convert the electrical signal into a digital signal, and send the digital signal to communication component 322.

For example, as described above, determination component 324, processor 312, memory 316, modem 320, and / or application 375 of BS 105 may determine an exit sequence for multiple vehicles to leave a parking area.

[0086] In certain implementations, the determining component 324, the processor 312, the memory 316, the modem 320, and / or the application 375 may be configured to and / or may define means for determining an exit order for a plurality of vehicles to exit a parking area.

[0087] At block 615, method 600 may send multiple departure commands for multiple vehicles to leave the parking area to multiple UEs based on the departure order. For example, the communication component 322, transceiver 302, receiver 306, transmitter 308, RF front end 388, subcomponents of RF front end 388, processor 312, memory 316, modem 320 and / or application 375 of BS105 may send multiple departure commands for multiple vehicles to leave the parking area to multiple UEs based on the departure order. The communication component 322 may send a digital signal to the transceiver 302 or transmitter 304. The transceiver 302 or transmitter 304 may convert the digital signal into an electrical signal and send it to the RF front end 388. The RF front end 388 may filter and / or amplify the electrical signal. The RF front end 388 may send the electrical signal as an electromagnetic signal via one or more antennas 365.

[0088] In certain implementations, the communication component 322, the transceiver 302, the receiver 306, the transmitter 308, the RF front end 388, subcomponents of the RF front end 388, the processor 312, the memory 316, the modem 320, and / or the application 375 may be configured as and / or may define components for sending multiple exit commands for multiple vehicles to exit a parking area to multiple UEs based on an exit order.

[0089] Alternatively or additionally, method 600 may also include any of the above methods, wherein receiving multiple requests includes receiving an emergency exit request from a first responder vehicle among the multiple vehicles, and wherein determining the exit order includes prioritizing the first responder vehicle in the exit order for the multiple vehicles. When determining the exit order, the first responder vehicle may be given priority.

[0090] Alternatively or additionally, method 600 may also include any of the above methods, wherein the departure order includes determining the departure order based on one or more of a reception order associated with receiving the multiple requests, a proximity of the multiple vehicles to one or more exits of the parking area, a size of the multiple vehicles, a maneuverability of the multiple vehicles, an estimated duration for the multiple vehicles to leave the parking area, an estimated fuel consumption of the multiple vehicles, or a priority associated with the multiple requests.

[0097] Figure 7 An example of a method for receiving a departure command in a parking lot departure management system using V2X is shown. For example, the method 700 may be performed by one or more of the processor 212, memory 216, application 275, modem 220, transceiver 202, receiver 206, transmitter 208, RF front end 288, communication component 222, and / or one or more other components of the UE 110 in the wireless communication network 100.

[0098] At block 705, the method 700 may send a leave request to a roadside unit (RSU). For example, as described above, the communication component 222, transceiver 202, receiver 206, transmitter 208, RF front end 288, subcomponents of RF front end 288, processor 212, memory 216, modem 220, and / or application 275 of UE 110 may send a leave request to a roadside unit (RSU). The communication component 222 may send a digital signal to the transceiver 202 or transmitter 204. The transceiver 202 or transmitter 204 may convert the digital signal into an electrical signal and send it to the RF front end 288. The RF front end 288 may filter and / or amplify the electrical signal. The RF front end 288 may send the electrical signal as an electromagnetic signal via one or more antennas 265.
