However, the disclosure is not limited to the terms and the names and may also be applied to systems conforming to other standards.

[0026] According to one or more embodiments, the wireless communication system may be an NR system, a fifth generation (5G) system, an LTE system, a code division multiple access (CDMA) system, a global system for mobile communications (GSM) system, a wireless local area network (WLAN) system, or any other wireless communication system. In the following, it is assumed that the wireless communication system is an NR system, an LTE system, or a communication supportable system based on NR and LTE, but the disclosed embodiments are not limited thereto.

[0027] According to one or more embodiments, a terminal may be referred to as, for example, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), a user terminal, a subscriber station (SS), a wireless device, a handheld device, etc.

[0028] According to one or more embodiments, the terminal may support fourth generation (4G) communication (eg, LTE or advanced LTE (LTE-A)) defined in the 3GPP standard, 5G communication (eg, NR), and the like.

[0029] In one embodiment, for 4G communication and 5G communication, the terminal may support a communication protocol based on CDMA, a communication protocol based on wideband CDMA (WCDMA), a communication protocol based on time division multiple access (TDMA), a communication protocol based on frequency division multiple access (FDMA), a communication protocol based on orthogonal frequency division multiplexing (OFDM), a communication protocol based on cyclic prefix (CP)-OFDM, a communication protocol based on discrete Fourier transform-spread-OFDM (DFT-s-OFDM), a communication protocol based on non-orthogonal multiple access (NOMA), a communication protocol based on generalized frequency division multiplexing (GFDM), and the like.

[0030] According to one or more embodiments, a vehicle may include a telematics control unit (TCU), an in-vehicle infotainment system (IVI), and an advanced driver assistance system (ADAS).

[0031] In one embodiment, wired / wireless communication may be performed based on any one of 5G communication (NR) (e.g., FR-1 or FR-2 frequency band of 5G communication), 4G communication (LTE or LTE-A), ultra-wideband (UWB), wireless fidelity (WiFi), Bluetooth, or universal serial bus (USB) through which high-speed data transmission between the terminal and the electronic device is possible.

[0032] According to one or more embodiments, a base station may be referred to as a fixed station configured to communicate with a terminal and / or another base station. For example, a base station may be referred to as a node B, an evolved node B (eNB), a sector, a site, a base transceiver system (BTS), an access point (AP), a relay node, a remote radio head (RRH), a radio unit (RU), etc. For example, in a wireless communication system, a base station includes at least one cell, which is the smallest unit of an area for providing communication services in each base station. The base station can provide efficient multiple access communications to multiple terminals based on specific frequency resources allocated to each cell. Specifically, in a multiple-input multiple-output (MIMO) system, a terminal and a base station can perform wireless communications based on multiple component carriers.

[0033] In the specification, a reduced private network is a network used for data transmission and reception between a vehicle and devices in the vehicle (for example, an on-board terminal and / or a vehicle IoT device), and may indicate a network that skips some processes or reduces some functions from the processes or functions for wireless communication between devices in the 3GPP LTE or NR communication standards based on the characteristics of data transmission and reception between the vehicle and the devices in the vehicle.

[0034] In the 3GPP specification, a reduced eNB (Red-eNB) modem is an eNB modem configured to perform the minimum (minimal) operation for data transmission and reception between a vehicle (or an electronic device of a vehicle) and a terminal (or an IoT device) in a reduced private network, and may be an eNB modem that reduces some functions from the functions of an existing eNB modem (e.g., a base station modem in a 3GPP LTE or NR wireless communication system). Here, the minimum (minimal) operation for data transmission and reception may include an operation of establishing a wireless communication channel between a vehicle (or an electronic device of a vehicle) and a terminal (or an IoT device) in a reduced private network (e.g., an operation of allocating resources for data transmission and reception), and an operation of performing communication through the established wireless communication channel (e.g., an operation of data transmission and reception using the allocated resources). For example, the Red-eNB modem may skip at least one process (or operation) among an initial access process, a random access process, a channel state-related measurement / report process, a carrier aggregation process, and / or a handover-related measurement / report process between a vehicle (or an electronic device of a vehicle) and a terminal (or an IoT device).

[0035] In the 3GPP specification, an IoT device is a device (e.g., sensor, camera, etc.) that can communicate wirelessly with a vehicle (e.g., the vehicle's electronic device) and can be installed on the exterior or interior structure of the vehicle. For example, an IoT device refers to a complex system of components (e.g., sensors, cameras, global positioning system (GPS) trackers) that connect to the cloud and provide real-time data, enabling more efficient transportation management and other services (such as advanced driver assistance systems (ADAS), object recognition, real-time route visibility, metal inspection, quality control, vehicle inspection, autonomous driving systems, vehicle safety, fleet management, and software updates).

[0036] In the specification, a reduced capability (RED-CAP) modem is a modem of an IoT device and may indicate a modem in which specifications of some hardware components (e.g., the number of antennas, access frequency band, and signal modulation scheme) are restricted according to characteristics of a reduced dedicated network of a UE modem from the LTE / NR standard.

[0037] Figure 1 An operation method between the electronic device 110 and the terminal 200 according to one or more embodiments is shown. The electronic device 110 may be provided as a part of the vehicle 100 or installed in the vehicle 100, and the terminal 200 may be a user equipment (UE) or a mobile device (such as a smart phone carried by a driver or a passenger of the vehicle), but is not limited thereto.

[0038] Recently, IVI can provide complex services that integrate vehicle-related services and mobile communication-related services based on IoT in the terminal 200 or the vehicle 100. However, LTE or NR defined in the 3GPP communication standard involves data transmission and reception (e.g., wireless communication) between a base station and a terminal. LTE or NR defines an initial access procedure, a random access procedure, a handover procedure, a carrier aggregation procedure, etc., but these procedures are procedures for controlling a random terminal that moves, and when the base station performs the corresponding procedure, considerable control overhead may be incurred.

[0039] 3GPP's Cellular Vehicle-to-Everything (C-V2X) is a vehicle communication technology for a vehicle to exchange information with another vehicle, traffic infrastructure, pedestrians, networks, etc. through a cellular mobile communication network (such as an LTE or NR network). LTE or NR sidelink communication defined for C-V2X is an inter-device communication method based on a source identifier Source_ID and a destination identifier Destination_ID between mobile devices (e.g., a vehicle and another vehicle) using a resource pool. LTE or NR sidelink communication between mobile devices may cause considerable control overhead in data transmission and reception processing, or the modem chip in a commercialized device may not support C-V2X.

[0040] Therefore, according to one or more embodiments, an electronic device 110 and an operating method of the electronic device 110 may be provided to minimize the control overhead in the data transmission and reception processing between the electronic device 110 and a vehicle-mounted device (e.g., a terminal or IoT device) by skipping or reducing some processes / functions from various processes / functions defined in existing 3GPP communication standards (e.g., LTE and NR standards) according to the characteristics of a streamlined dedicated network in the vehicle 100.

[0041] Reference Figure 1 , a wireless communication system according to one or more embodiments may include: a vehicle 100 including an electronic device 110 , a terminal 200 located in the vehicle 100 , and a base station.

[0042] exist Figure 1 In the present invention, the vehicle 100 and the base station establish a wireless communication connection based on a cellular mobile communication network, and the vehicle 100 and the terminal 200 establish a wireless communication connection based on a simplified private network. Here, the simplified private network is a network used for data transmission and reception between the vehicle and the device in the vehicle (for example, the vehicle-mounted terminal and / or the vehicle IoT device). The simplified private network may indicate a network that skips some processes or reduces some functions from the processes or functions for wireless communication between devices in the 3GPP LTE or NR communication standards based on the data transmission and reception characteristics between the vehicle and the device in the vehicle.

[0043] In one embodiment, in operation S10, the vehicle 100 (e.g., the electronic device 110 of the vehicle 100) and the terminal 200 may perform a connection for inter-device wireless communication based on a simplified dedicated network. For example, the vehicle 100 and the terminal 200 may skip at least one of the initial access process, random access process, channel state-related measurement / report process, carrier aggregation process, and switching-related measurement / report process in the 3GPP LTE or NR communication standard. At least one process establishes a wireless communication connection between the electronic device 110 and the terminal 200 (or IoT device) based on pre-stored pre-connection information. Figure 3 Describe it in detail.

[0044] In one embodiment, in operation S13, the vehicle 100 (e.g., the electronic device 110 of the vehicle 100) and the terminal 200 may exchange data between them through the simplified dedicated network. For example, the vehicle 100 (e.g., the electronic device 110 of the vehicle 100) may perform a target task based on the data (e.g., uplink data) received from the terminal 200.

[0045] In one embodiment, reference has been made to Figure 1The data transmission and reception operation based on the simplified private network between the vehicle 100 (e.g., the electronic device 110 of the vehicle 100) and the terminal 200 is described, but the disclosed embodiments are not limited thereto. The vehicle 100 (e.g., the electronic device 110 of the vehicle 100) according to one or more embodiments may also perform data transmission and reception with the vehicle IoT device based on the simplified private network. Figures 4 to 6 The disclosed embodiments are described.

[0046] In one embodiment, in operation S15 , the vehicle 100 (eg, the electronic device 110 of the vehicle 100 ) and the terminal 200 may disconnect the wireless communication connection based on the reduced dedicated network.

In one embodiment, each of the TCU 111 and the antenna module 112 may be a process as a set of multiple instructions executed by the processor 113, and may be stored in the memory 116 accessible by the processor 113.

[0053] In one embodiment, the processor 113 may control the first modem 114 to establish a first wireless communication connection with the base station based on at least one pre-connection information pre-stored in the memory 116, and control the second modem 115 to establish a second wireless communication connection between the vehicle 100 (or the electronic device 110) and the terminal 200. In one embodiment, the processor 113 may control the second modem 115 to establish a third wireless communication connection between the vehicle 100 (or the electronic device 110) and the IoT device based on at least one pre-connection information pre-stored in the memory 116. Figure 3 Describe it in detail.

[0054] In one embodiment, the processor 113 may control the second modem 115 to perform the minimum (minimal) operation for the second wireless communication connection and / or the third wireless communication connection. In one embodiment, the processor 113 may skip at least one of the initial access process (e.g., beam management process, physical random access channel (PRACH) process, single sideband (SSB) process, physical broadcast channel (PBCH) process, etc.), random access process, carrier aggregation process, and handover-related measurement / reporting process between the electronic device 110 and the terminal 200 (or IoT device), and control the second modem 115 to establish the second wireless communication connection and / or the third wireless communication connection based on the pre-stored pre-connection information by replacing the above process. Here, the pre-connection information may include at least one of access band information, system information, radio resource control (RRC) initial configuration value information, and registered device identification information.

[0055] In one embodiment, the processor 113 may skip the channel state related measurement / reporting process between the electronic device 110 and the terminal 200 (or IoT device), and by replacing the above process, control the second modem 115 to adjust the modulation and coding scheme (MCS) level of the data to be sent to the terminal 200 (or IoT device) in response to (based on) a message confirmation / negative confirmation (ACK / NACK) received from the terminal 200 (or IoT device).

[0056] In one embodiment, the processor 113 may control the second modem 115 to perform a discontinuous reception (DRX) operation based on the data transmission volume through the second wireless communication connection or the third wireless communication connection.

[0057] In one embodiment, if there is another terminal that has already performed a wireless communication connection with the electronic device 110, the processor 113 may control the second modem 115 to send data to the terminal 200 and the other terminal through a time division multiplexing (TDM) scheme based on information pre-stored in the memory 116 (e.g., information about the number of terminals that can be supported simultaneously and time division multiplexing (TDM) configuration information).

[0058] In one embodiment, the processor 113 may perform a target task based on terminal data (eg, Universal Subscriber Identity Module (USIM) data or application data) received through the second wireless communication connection. Figure 5 and Figure 6 Describe it in detail.

[0059] In one embodiment, the processor 113 may receive IoT device information via a third wireless communication connection and send the IoT device information to a controller of the vehicle 100 for use in improving the capabilities of the vehicle 100. Figure 4 Describe it in detail.

[0060] In one embodiment, the first modem 114 and the second modem 115 may be operably (electrically or physically) connected to the antenna module 112, and may control the operation and / or function of the antenna module 112. For example, the first modem 114 and the second modem 115 may establish a direct (e.g., wired) communication channel or a wireless communication channel between the vehicle 100 and an external electronic device (e.g., the terminal 200, an IoT device, or a base station), and support communication through the established communication channel.

[0061] In one embodiment, the first modem 114 may include a TCU modem (or UE modem) configured to perform wireless communication between the vehicle 100 (e.g., the electronic device 110) and a base station in a 3GPP LTE or NR wireless communication network. For example, the first modem 114 may include a TCU modem (or UE modem) designed based on the 3GPP LTE or NR communication standard.

[0062] In one embodiment, the first modem 114 may establish a first wireless communication connection between the vehicle 100 (eg, the electronic device 110 of the vehicle 100 ) and a base station, for example, via a Uu interface.

Here, the minimum (minimal) operation for data transmission and reception may include an operation of establishing a wireless communication channel between the vehicle 100 (or the electronic device 110) and the terminal 200 (or IoT device) in the reduced private network (e.g., an operation of allocating resources for data transmission and reception), and an operation of performing communication through the established wireless communication channel (e.g., a data transmission and reception operation using the allocated resources).

In one embodiment, the second modem 115 may be implemented as a Red-eNB modem by reusing or partially changing at least one hardware module of the existing TCU modem (e.g., the first modem 114) (e.g., the antenna module, Tx chain, and MIMO layer of the existing TCU modem). For example, the second modem 115 may be operated as a Red-eNB modem by using two antennas (e.g., included in the antenna module 112), two Tx chains, and two MIMO layers of the existing TCU modem (e.g., the first modem 114).

[0066] In one embodiment, the second modem 115 may be implemented as a Red-eNB modem by updating software of an existing TCU modem (e.g., the first modem 114). In one embodiment, the second modem 115 as a Red-eNB modem may include at least one module that is the same as the hardware module and / or software module included in the first modem 114.

[0067] In one embodiment, by updating the software of the UE modem according to the existing LTE / NR standard, the modem of the terminal 200 in the reduced dedicated network can be implemented as a Red-UE modem.

[0068] In one embodiment, the second modem 115 may establish a second wireless communication connection between the vehicle 100 (eg, the electronic device 110 of the vehicle 100 ) and the terminal 200 based on (or through) the reduced dedicated network.

[0070] In one embodiment, the memory 116 may include, for example, a non-volatile memory (including at least one of a flash memory, a hard disk memory, a multimedia card memory, a micro card memory (e.g., a secure digital (SD) or extreme digital (XD) memory, etc.), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), and a programmable read-only memory (PROM)) and a volatile memory (such as a random access memory (RAM) or a static random access memory (SRAM)). The memory 116 may store instructions, data structures, and program codes that can be read by the processor 113. In the following embodiments, the processor 113 may be executed by executing instructions or codes of a program stored in the memory 116.

In one embodiment, the base station 300 performs a wireless communication connection with the core network 400, for example, according to the 3GPP LTE or NR communication standard to support the wireless communication connection between the above-mentioned devices.

[0080] exist Figure 3 In the present invention, a streamlined dedicated network is used for data transmission and reception between a vehicle and devices in the vehicle (e.g., an on-board terminal and / or a vehicle IoT device), and may indicate a network that skips some processes or reduces some functions from processes or functions used for wireless communication between devices (e.g., in 3GPP LTE or NR communication standards) based on the characteristics of data transmission and reception between the vehicle and the devices in the vehicle.

[0081] Reference Figure 3 , the vehicle 100 may include an electronic device 110 , an IoT device (eg, a first IoT device 171 and a second IoT device 172 ), an ADAS 180 , and an IVI 185 , and the electronic device 110 may include a first modem 114 and a second modem 115 .

[0082] In one embodiment, the modem of the IoT device (e.g., the first IoT device 171 or the second IoT device 172) may include a RED-CAP modem in which specifications of some hardware components are limited based on the characteristics of a reduced private network in a UE modem of the LTE / NR standard. In one embodiment, the IoT device includes a modem having at least one function among the functions of an existing telematics control unit (TCU) modem or a user equipment (UE) modem, and the at least one function corresponds to the characteristics of a third wireless communication connection with the IoT device. For example, the RED-CAP modem may include a modem that includes a predefined (or limited) number of antennas (e.g., one or two antennas), accesses through a specific access band (e.g., a 20Mhz band for FR-1 or a 100Mhz band for FR-2), and is based on a specific signal modulation scheme (e.g., 64QAM).

[0083] In one embodiment, the first modem 114 of the electronic device 110 may include a modem (e.g., a TCU modem or a UE modem according to the LTE / NR standard) configured to support a first wireless communication connection between the electronic device 110 and the base station 300. In one embodiment, the second modem 115 of the electronic device 110 may include a Red-eNB modem configured to support a second wireless communication connection between the electronic device 110 and the terminal 200 in a reduced private network and / or a third wireless communication connection between the electronic device 110 and an IoT device (e.g., the first IoT device 171 or the second IoT device 172). For example, the second modem 115 may include a module that is the same as at least one of the hardware modules and / or software modules included in the first modem 114.

[0084] In one embodiment, the electronic device 110 may establish a first wireless communication connection with the base station 300 using the first modem 114. For example, the electronic device 110 may establish a first wireless communication connection with the base station 300 according to a procedure (e.g., an initial access procedure, a random access procedure, etc.) of a 3GPP LTE or NR communication standard. The electronic device 110 may perform a downlink operation of receiving data from the base station 300 and an uplink operation of sending data to the base station 300.

[0085] In one embodiment, the electronic device 110 can establish a second wireless communication connection with the terminal 200 or establish a third wireless communication connection with an IoT device (e.g., the first IoT device 171 or the second IoT device 172) according to a reduced wireless communication connection process through a second modem 115 (e.g., a Red-eNB modem).

[0086] In one embodiment, the electronic device 110 may skip at least one of the initial access process (e.g., beam management process, PRACH process, SSB process, PBCH process, etc.), random access process, carrier aggregation process and / or handover-related measurement / reporting process between the electronic device 110 and the terminal 200 (or IoT device) by controlling the second modem 115 according to the reduced wireless communication connection process. In addition, the electronic device 110 may control the second modem 115 according to the reduced wireless communication connection process to establish a second wireless communication connection and / or a third wireless communication connection based on the pre-stored pre-connection information by replacing the above-mentioned process (at least one of the initial access process, random access process, carrier aggregation process and / or handover-related measurement / reporting process). Here, the pre-connection information may include at least one of access band information, system information, RRC initial configuration value information and registered device identification information. The access band information may include at least one of center frequency information, BW information and BWP information. The system information may include at least one of MIB information and SIB information.

[0087] For example, the electronic device 110 may enter an RRC-connected (RRC-CONNECTED) mode with the terminal 200 (e.g., an IoT device) by skipping an access band search process according to a reduced wireless communication connection process by using pre-connection information (e.g., access band information) and establishing a second wireless communication connection and / or a third wireless communication connection according to timing synchronization. In the RRC-CONNECTED mode, the electronic device 110 may send a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH) to the terminal 200 (or the IoT device) and receive a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) from the terminal 200 (or the IoT device) through the second modem 115. For example, in the RRC-CONNECTED mode, the electronic device 110 may confirm the completion of the second wireless communication connection between the electronic device 110 and the terminal 200 by receiving a PUCCH from the terminal 200.

[0088] In one embodiment, the electronic device 110 may control the second modem 115 to skip the channel state related measurement / reporting process between the electronic device 110 and the terminal 200 (or IoT device) according to the reduced wireless communication connection process, and adjust the MCS level of the data to be sent to the terminal 200 (or IoT device) in response to the message (ACK / NACK) received from the terminal 200 (or IoT device) by replacing the above process. For example, if an ACK message is received from the terminal 200 (or IoT device), the electronic device 110 may increase the MCS level of the data to be sent to the terminal 200 (or IoT device) using the second modem 115. For example, if a NACK message is received from the terminal 200 (or IoT device), the electronic device 110 may reduce the MCS level of the data to be sent to the terminal 200 (or IoT device) using the second modem 115.

[0089] In one embodiment, the electronic device 110 may control the second modem 115 to perform the DRX operation based on the amount of data transmission through the second wireless communication connection or the third wireless communication connection according to the reduced wireless communication connection process. For example, the electronic device 110 may monitor uplink or downlink data for a first duration (e.g., wake-up duration) based on a predefined period, and stop monitoring for a second duration (e.g., sleep duration) to save battery.

[0090] In one embodiment, when the amount of data transmitted through the second wireless communication connection or the third wireless communication connection is less than a threshold value, the electronic device 110 may switch the mode of the second modem 115 from the RRC-CONNECTED mode to the RRC-IDLE mode. In one embodiment, when the amount of data transmitted through the second wireless communication connection or the third wireless communication connection is greater than or equal to a threshold value, the electronic device 110 may switch the mode of the second modem 115 from the RRC-IDLE mode to the RRC-CONNECTED mode.

[0091] In one embodiment, when there is another terminal that has already performed a wireless communication connection with the electronic device 110, the electronic device 110 may reduce the wireless communication connection process based on the pre-stored Figure 2 ) (e.g., information about the number of terminals that can be supported simultaneously and TDM configuration information) to control the second modem 115 to transmit data to the terminal 200 and another terminal through the TDM scheme. For example, if both the first terminal and the second terminal access the electronic device 110, the electronic device 110 can communicate with the first terminal based on the (2n-1)th time slot (n is a non-zero integer, for example, the 1st, 3rd, 5th time slot) allocated to the first terminal, and communicate with the second terminal based on the 2nth time slot (n is a non-zero integer, for example, the 2nd, 4th, 6th time slot) allocated to the second terminal.

[0092] In one embodiment, the electronic device 110 may perform an uplink operation of receiving data from the terminal 200 (or the IoT device (e.g., the first IoT device 171 or the second IoT device 172)) and a downlink operation of sending data to the terminal 200 (or the IoT device (e.g., the first IoT device 171 or the second IoT device 172)) based on a streamlined dedicated network (e.g., the second wireless communication connection or the third wireless communication connection).

[0093] According to one or more embodiments, the electronic device 110 can build a streamlined dedicated network by skipping some functions or processes in the existing LTE / NR (for example, at least one of the initial access process, the random access process, the channel state-related measurement / reporting process, the carrier aggregation process, and the switching-related measurement / reporting process) according to the reduced wireless communication connection process between the electronic device 110 and the terminal 200 (or the IoT device (for example, the first IoT device 171 or the second IoT device 172)), thereby minimizing the control overhead of the wireless communication connection between the devices.
