Description

Vehicle electronic device and operation method thereof

Various embodiments may provide an in-vehicle electronic device that communicates with an external device by controlling an antenna module based on location information of an obstacle and an operating method thereof.

With the advent of 5G mobile communication, various mobile communication services have increased dramatically. There is a limit to providing various mobile communication services only by increasing the efficiency of using the existing sub-6GHz band and increasing the capacity. In particular, 5G requirements include high data rates (eMMB), very low latency (URLLC), the ability to handle a large number of devices (eMTC), ultra-high reliability and energy efficiency. In order to satisfy these requirements, research on a 5G RAN (Radio access network) system to which a new mmWave-based radio access technology is applied is being actively conducted.

As users' data demands continue to increase, 5G required the introduction of various technologies to significantly increase data capacity compared to existing 4G communication technologies. Among them, a millimeter wave frequency band is used as a way to additionally secure a radio frequency band.

The currently commercialized and used millimeter wave frequency band is 28 GHz to 100 GHz, and there is a continuous wide bandwidth that can be used compared to the existing band below 6 GHz. Therefore, the mmWave frequency band can be easily applied to various wireless access technologies suitable for service requirements. On the other hand, when a signal is transmitted in the form of a beam in the mmWave frequency band, a service area is narrowed due to a short radio wave reach, and radio interference/blocking may occur due to obstacles. In addition, there is a need for a communication method capable of satisfying requirements such as support for mobility and reliable data transmission in a millimeter wave frequency band.

According to one embodiment of the present disclosure, an electronic device for a vehicle may be provided. The vehicular electronic device may include a sensor module that collects surrounding environment information of a vehicle equipped with the vehicular electronic device; a communication module including an antenna module and communicating with an external device; a memory that stores one or more instructions; and a processor executing the one or more instructions stored in the memory. The processor may obtain location information of obstacles present around the vehicle based on the surrounding environment information. The processor may obtain antenna control information based on the location information of the obstacle. The processor may perform communication with the external device by controlling the antenna module based on the antenna control information.

In addition, terms such as "...unit" and "module" described in the specification mean a unit that processes at least one function or operation, which may be implemented as hardware or software or a combination of hardware and software. .

Hereinafter, with reference to the accompanying drawings, embodiments will be described in detail so that those skilled in the art can easily carry out the present invention. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

The currently commercialized and used millimeter wave (mmWave) frequency band is 28 GHz to 100 GHz, and there is a continuous wide bandwidth that can be used compared to the existing band below 6 GHz. Therefore, it may be easy to apply various radio access technologies suitable for service requirements. However, when the signal is transmitted in the form of a beam 130 as shown in FIG. 1 , the propagation distance of the signal is shortened according to the characteristics of the beam, and a narrow service area can be provided. In addition, a radio wave interference/blocking phenomenon may occur due to obstacles.

When a mmWave frequency signal is used, signal propagation problems such as path loss and nonline of sight (NLOS) may occur. Therefore, in a 5G (NR) communication system using a millimeter wave frequency signal, a base station (BS) 110 and a user equipment (UE) 100 form a narrow beam configured through beam adjustment (130) is used. The biggest challenge for using the narrow beam 130 is establishing and maintaining a communication link between the base station 110 and the user terminal 120 .

In order to establish and maintain a communication link, the base station 110 and the user terminal 100 must continuously select the

best beams

140 and 150. For example, in order to select an optimal beam, the base station 130 and the user terminal 100 (eg, a terminal mounted in a vehicle) must periodically perform beam monitoring and searching operations. In this case, problems of heat generation and power loss may occur due to periodic beam monitoring and searching operations.
