Description

Technical Field

[0001] The embodiments of this application relate to, but are not limited to, the field of communications, and particularly to an antenna determination method, apparatus, terminal, electronic device, and storage medium. Background Technology

[0002] Vehicle-to-Everything Communications (V2X) refers to the use of sensors, onboard terminals, and electronic tags installed in vehicles to provide vehicle information. It employs various communication technologies to achieve vehicle-to-vehicle communication (V2V), vehicle-to-pedestrian communication (V2P), vehicle-to-infrastructure communication (V2I), and vehicle-to-network communications (V2N). The information is then extracted, shared, and effectively utilized on an information network platform to effectively manage vehicles and provide comprehensive services.

[0003] Currently, there are two resource allocation methods for V2X: one is the base station (eNB) scheduling method, and the other is the user equipment (UE) autonomous resource selection method. V2X direct link communication based on the UE autonomous resource selection method does not occupy base station resources, but its communication latency and quality still cannot meet the requirements. Therefore, there is an urgent need for a communication method that can achieve lower latency and higher reliability to reduce resource congestion and conflicts. Summary of the Invention

Under the premise of establishing a communication connection with the other terminal, by comparing the quality of the signals received by at least two of its own antennas, the channel corresponding to the signal with better signal quality is selected as the communication channel, and the antenna corresponding to the communication channel is determined as the working antenna of the terminal for subsequent signal transmission and reception. This can effectively reduce communication latency, improve communication quality, and enable timely and effective sharing of acquired data information with other terminals.

[0006] In a first aspect, embodiments of this application provide an antenna determination method.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] In the description of the embodiments of this application, unless otherwise expressly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this application in combination with the specific content of the technical solution.

[0023] Currently, there are two resource allocation methods for V2X: one is the base station (eNB) scheduling method, and the other is the user equipment (UE) autonomous resource selection method. V2X direct link communication based on the UE autonomous resource selection method does not occupy base station resources, but its communication latency and quality still cannot meet the requirements. Therefore, there is an urgent need for a communication method that can achieve lower latency and higher reliability to reduce resource congestion and conflicts.

[0024] Based on this, embodiments of this application provide an antenna determination method, apparatus, vehicle network terminal, electronic device, and storage medium. Under the premise of establishing a communication connection with the counterpart terminal, by comparing the quality of the signals received by at least two of its own antennas, the channel corresponding to the signal with better signal quality is selected as the communication channel, and the antenna corresponding to the communication channel is switched for subsequent signal transmission and reception. In V2X direct link communication based on the UE's autonomous resource selection method, it can effectively reduce communication latency, improve communication quality, and enable timely and effective sharing of important information such as vehicle speed, direction, geographical location, and route with other terminals in the vehicle network.

[0025] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0026] In a first aspect, embodiments of this application provide an antenna method. Figure 1 This is a flowchart illustrating the antenna determination method provided in an embodiment of this application. Figure 1 As shown, the antenna determination method provided in this embodiment includes at least:

[0027] Step S100: Establish a communication connection with the second terminal.

[0028] The antenna determination method involved in this embodiment is applied to the first terminal. Therefore, in this step, the first terminal first establishes a communication connection with the second terminal. The method for establishing the communication connection can be that the first terminal sends connection information to the second terminal via an antenna, and the second terminal uses one or more antennas to receive data, thus establishing a communication connection with the first terminal; alternatively, the second terminal can send connection information to the first terminal via an antenna, and the first terminal uses one or more antennas to receive data, thus establishing a communication connection with the second terminal.

[0029] Step S200: Obtain the received signal of the first antenna and the received signal of the second antenna.

[0030] It is worth noting that the first terminal has at least two antennas; that is, the first terminal can have three, four, or even more antennas. These antennas are preferably oriented in different directions to improve the accuracy and sensitivity of signals transmitted from different locations. Those skilled in the art will understand that these antennas can be directional antennas or antenna arrays. Combined with beamforming technology for directional antennas, these antennas oriented in different directions can achieve low latency and high quality communication.

[0031] After the communication connection is established, the second terminal transmits a reference signal to the first terminal through its antenna. The reference signal is used for subsequent evaluation of channel quality.

[0032] In one embodiment, the second terminal has four antennas, so the second terminal sends reference signals to the first terminal through the four antennas respectively.

[0033] Preferably, the second terminal transmits reference signals through four antennas within a defined period, and the transmission signals from the four antennas are spaced apart by time intervals. Transmitting signals through different antennas at different times avoids mutual interference between antenna signals, making subsequent assessments of channel quality more accurate.

[0034] The first terminal receives the reference signal transmitted by the second terminal through two or more antennas. That is, for the first terminal, the first terminal obtains the received signal from the first antenna and the received signal from the second antenna. Here, the received signal is the reference signal.

[0035] In one embodiment, corresponding to the second terminal having 4 antennas, the first terminal also has 4 antennas, and the 4 antennas of the first terminal respectively receive reference signals from the 4 antennas of the second terminal.

[0036] Step S300: Compare the quality of the received signal with the first signal quality threshold respectively, and select the channel corresponding to the received signal whose signal quality is greater than the first signal quality threshold as the communication channel.

[0037] The first terminal has at least a first antenna and a second antenna, thus obtaining at least two received signals. The signal quality of each received signal is then calculated separately. The evaluation parameters for the signal quality of the received signals include the received power of the reference signal, the signal-to-interference-plus-noise ratio, the received signal strength indication, and the received quality of the reference signal. Those skilled in the art should understand that signal quality can be evaluated through multiple dimensions and methods; therefore, any parameters and methods that can be used to evaluate signal quality are within the protection scope of step S300 in the embodiments of this application.

[0038] In one embodiment, the reference signal received power is used as an evaluation index of signal quality; that is, the higher the reference signal received power of the received signal, the higher the signal quality.

[0039] By pre-setting a first signal quality threshold, signals whose signal quality meets the requirements and their corresponding channels are selected.

[0040] In one embodiment, as long as the signal quality is greater than the first signal quality threshold, the channel corresponding to the above signal can be used as a transmission channel, wherein there can be one or more transmission channels.

[0041] In another embodiment, the channel corresponding to the signal with the best signal quality is selected as the transmission channel.

[0042] Step S400: Determine the antenna corresponding to the communication channel as the terminal's working antenna.

[0043] After the communication channel is determined, the first terminal selects the antenna corresponding to the communication channel as the subsequent transmitting and receiving antenna, that is, the first terminal will switch to the antenna corresponding to the communication channel.

[0044] Through the embodiments of this application, those skilled in the art should understand that the first terminal using this antenna determination method should have at least two antennas, while the second terminal sending a reference signal to the first terminal may have one or more antennas. Furthermore, the transmitting antenna obtained through this antenna determination method can be one or more, because in actual operation, the terminal may be involved in a state where multiple antennas are used for simultaneous transmission.

[0045] The antenna determination method provided in this embodiment can, under the premise of establishing a communication connection with the other terminal, select the channel corresponding to the signal with better signal quality as the communication channel by comparing the quality of the signals received by at least two of its own antennas, and switch to the antenna corresponding to the communication channel for subsequent signal transmission and reception. In V2X direct link communication based on the UE's autonomous resource selection method, it can effectively reduce communication latency, improve communication quality, and enable timely and effective sharing of important information such as vehicle speed, direction, geographical location, and route with other terminals.

[0046] Figure 2 This is a schematic diagram of a terminal system provided in an embodiment of this application.

[0047] like Figure 2 As shown, the terminal system includes a first terminal and a second terminal. Figure 2 The left side represents the first terminal, and the right side represents the second terminal. The first terminal has one transmit / receive module that can support both transmission and reception, and three receive modules. These four modules are connected to four antennas via a 4P4T multi-pole multi-throw RF switch. The second terminal also has one transmit / receive module that can support both transmission and reception, and three receive modules. These four modules are connected to four antennas via a 4P4T multi-pole multi-throw RF switch.

[0048] The flowchart of the antenna determination method for the terminal system provided in this embodiment is as follows: Figure 3 As shown, it includes at least:

[0049] Step S101: The first terminal uses the first antenna to send a connection signal to the second terminal and establishes a communication connection with the second terminal.

[0050] In this embodiment, the first terminal sends connection information to the second terminal via an antenna, and the second terminal uses one or more antennas to receive data and establish a communication connection with the first terminal.

[0051] Step S102: The receiving module of the first terminal temporarily stops working, and the transmitting module transmits reference signals to the second terminal from the first antenna, the second antenna, the third antenna and the fourth antenna respectively within the first time period.

[0052] In this embodiment, the second terminal has four antennas. Therefore, the first terminal periodically sends reference signals to the second terminal through the four antennas. That is, within a certain time period, the first terminal sends reference signals to the second terminal from the first antenna, the second antenna, the third antenna, and the fourth antenna, respectively.

[0053] In this embodiment, corresponding to the first terminal with 4 antennas, the second terminal also has 4 antennas, and the 4 antennas of the second terminal respectively receive reference signals from the 4 antennas of the second terminal.

[0054] Step S103: The second terminal performs channel estimation through the received signals from the 4-channel receiving module, and determines the channel quality of the transmission path from the first terminal to the second terminal by using the reference signal received power.

[0055] In this embodiment, the reference signal received power is used as an evaluation index of signal quality; that is, the higher the reference signal received power of the received signal, the higher the signal quality.

[0056] Step S104: The second terminal uses the antenna corresponding to the channel with the best signal quality as the antenna for subsequent communication with the first terminal.

[0057] In this embodiment, based on the calculation of the reference signal received power for each received signal, the channel corresponding to the received signal with the highest reference signal received power is taken as the communication channel, and the second terminal determines the antenna corresponding to the communication channel as the antenna.

[0058] Through the above steps, the second terminal has switched its antenna to an antenna that can communicate with the first terminal and has better channel quality. Before the next antenna switching scheme is executed, the second terminal will use the above antenna to communicate with the first terminal.

[0059] Accordingly, in order to switch to an antenna that can communicate with the second terminal and has better channel quality, the first terminal also repeats the above steps S101 to S104.

[0060] The terminal system provided in this embodiment can, under the premise of establishing a communication connection with the other terminal, select the channel corresponding to the signal with better signal quality as the transmission channel by comparing the quality of the signals received by at least two of its own antennas, and switch to the antenna corresponding to the transmission channel for subsequent signal transmission and reception. In V2X direct link communication based on the UE's autonomous resource selection method, it can effectively reduce communication latency, improve communication quality, and achieve timely and effective sharing of important information such as vehicle speed, direction, geographical location, and route with other terminals.

[0061] Figure 4 This is a schematic diagram of a V2X terminal provided in another embodiment of this application. Figure 4 The system includes a V2X terminal, specifically a vehicle-mounted terminal. This vehicle-mounted terminal comprises two transmitter / receiver modules, a first transmitter / receiver module and a second transmitter / receiver module, each capable of both transmitting and receiving signals. Because signal transmission and reception between the two transmitter / receiver modules can interfere with each other, each transmitter / receiver module is connected to a different switch. A first antenna is connected to a first switch, second and third antennas are connected to second switches respectively, and a fourth antenna is connected to a third switch. These three switches are either single-pole three-throw switches or triple-pole three-throw switches, used to select the appropriate antenna and corresponding module.

[0062] The flowchart of the antenna determination method for the V2X terminal provided in this embodiment is as follows: Figure 5 As shown, it includes at least:

[0063] Step S201: The vehicle terminal uses the first antenna to send a connection signal to the roadside unit (RSU) and establishes a communication connection with the RSU.

[0064] Step S202: The receiving module of the vehicle terminal is temporarily set to work, and the first transmitting module transmits reference signals to the roadside unit (RSU) from the first antenna, the second antenna, the third antenna and the fourth antenna respectively within the first time period.

[0065] Step S203: The roadside unit (RSU) performs channel estimation using the received signals from the four receiving modules, and determines the channel quality of the transmission path from the vehicle terminal to the roadside unit (RSU) by using the reference signal received power.

[0066] Step S204: The roadside unit (RSU) determines the antenna corresponding to the channel with the best signal quality as the first transceiver antenna for subsequent communication with the vehicle terminal.

[0067] Step S205: The receiving module of the vehicle terminal continues to operate temporarily, and the second transmitting module transmits reference signals to the roadside unit (RSU) from the first antenna, the second antenna, the third antenna, and the fourth antenna respectively during the second time period.

[0068] Step S206: The roadside unit (RSU) performs channel estimation using the received signals from the four receiving modules, and determines the channel quality of the transmission path from the vehicle terminal to the roadside unit (RSU) by using the reference signal received power.

[0069] Step S207: The roadside unit (RSU) uses the antenna corresponding to the channel with the best signal quality as the second transmitting antenna for subsequent communication with the vehicle terminal.

[0070] Steps S201 to S204 above constitute the transmission process of the reference signal of the vehicle terminal based on the first transmitting module. The roadside unit (RSU) on the opposite side receives, calculates and compares the reference signal through its at least two antennas to determine the best antenna that can communicate with the antenna supported by the first transmitting module of the vehicle module, namely the first communication antenna.

[0071] Steps S205 to S207 are basically the same as steps S202 to S204. The only difference is that the above steps are based on the transmission process of the reference signal of the vehicle terminal of the second transmission module. The roadside unit RSU on the opposite side receives, calculates and compares the above reference signal through its at least two antennas to determine the best antenna that can communicate with the antenna supported by the second transmission module of the vehicle module, namely the second transceiver antenna.

[0072] Those skilled in the art will recognize that vehicle-mounted terminals, roadside units, mobile phones, and other fixed or mobile terminals in V2V, V2N, V2P, and V2I systems can all adopt the antenna determination method provided in the above embodiments, as well as the terminal structure adapted to the antenna determination method.

[0073] Meanwhile, since vehicle-to-everything (V2X) terminals are often constantly moving, when a terminal detects that the quality of the received signal has significantly decreased or is less than the preset second signal quality threshold, it will re-execute the antenna determination method to use the antenna corresponding to the channel with the best quality for transmission and reception in real time.

[0074] The terminal system provided in this embodiment can, under the premise of establishing a communication connection with the other terminal, select the channel corresponding to the signal with better signal quality as the communication channel by comparing the quality of the signals received by at least two of its own antennas, and switch to the antenna corresponding to the communication channel for subsequent signal transmission and reception. In V2X direct link communication based on the UE autonomous selection of resources, it can effectively reduce communication latency, improve communication quality, and achieve timely and effective sharing of important information such as vehicle speed, direction, geographical location, and route with other terminals in the vehicle network.

[0075] Figure 6 This is a schematic diagram of a V2X system terminal provided in another embodiment of this application.

[0076] Those skilled in the art should also know that when both the first terminal and the second terminal achieve high-quality, low-latency communication using the antenna determination method provided in the above embodiments, and when both the first terminal and the third terminal achieve high-quality, low-latency communication using the antenna determination method provided in the above embodiments, the second terminal and the third terminal can communicate with each other through the first terminal. In this case, the first terminal functions as a base station and is used for resource allocation.

[0077] When the second terminal and the third terminal are too far apart to communicate directly via a direct link, this indirect communication method can solve the above problem.

[0078] In this embodiment, the vehicle-mounted terminal located in the center of the diagram has four antennas facing forward, backward, left, and right. Based on the antenna determination method provided in the above embodiment, the vehicle-mounted terminal may use the antenna facing left when communicating with the vehicle-mounted terminal on the left, and similarly, it may use the antenna facing right when communicating with the roadside unit on the right. These antennas can ensure optimal communication quality and minimal latency. When the vehicle-mounted terminal achieves communication with both the vehicle-mounted terminal on the left and the roadside unit on the right, it can be used as a base station to enable communication between the vehicle-mounted terminal on the left and the roadside unit on the right.
