[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure claims priority to Chinese Patent Application No. 201910723741.5, filed on Aug. 07, 2019, the entire contents of which are hereby incorporated by reference into this disclosure.
[0002] The present disclosure relates to an electronic device and method in a wireless communication system, and more particularly to an electronic device and method for performing multicast communication in a wireless communication system. [Background technology]
[0003] With the development of communication technology, the requirements for reliability and latency in communication are increasing, and Ultra-Reliable Low-Latency Communication (URLLC) is attracting more and more attention as one of the main scenarios that need to be considered in the 5th generation communication system. For example, in machine-type communication (MTC) such as vehicle-to-vehicle (V2V), factory automation cases, point-to-point communication (P2P), wireless sensor network (WSN), etc., it is considered that the URLLC service can be applied to meet the quality of service (QoS) requirements of machine-type communication.
[0004] To realize gigabit-level wireless access that meets URLLC requirements, millimeter wave and large-scale I / O technologies are being actively researched. Large-scale I / O technologies with high flexibility can ensure relatively high energy efficiency and spectrum efficiency, while providing a wider available bandwidth in the millimeter wave band. In addition, because millimeter waves have a relatively short wavelength, they can be equipped with a large number of antenna arrays to form highly directional beams, making large-scale I / O systems feasible.
[0005] Using a direct link (sidelink) to perform multicast communication is a common scenario in wireless communication. For example, in a vehicle-to-vehicle (V2V) communication scenario, vehicles can form a driving mode based on a platoon. In each platoon, the leading vehicle uses the direct link to transmit its own acquired sensory data (e.g., data acquired by an on-board camera or radar) to the following vehicles in a multicast communication manner. However, since the length, shape and surrounding environment of the platoon are constantly changing, the communication quality between the leading vehicle and the following vehicles may deteriorate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] While the embodiments described in this disclosure are susceptible to modification and alternative forms, specific embodiments thereof are shown by way of example in the accompanying drawings and are herein described in detail. It should be understood, however, that the accompanying drawings and detailed description thereto are not intended to limit the embodiments to the particular forms disclosed herein, but on the contrary, are intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the appended claims.
[0019] The following describes exemplary embodiments of the present disclosure in conjunction with the accompanying drawings. For clarity and conciseness, not all features of the embodiments are described in the specification. However, it should be understood that during the implementation of the embodiments, many implementation-specific settings must be made to achieve the developer's specific goals, for example, to meet the constraints of devices and services, and these constraints may vary from embodiment to embodiment. It should also be understood that although the development work may be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the present disclosure.
[0020] It should be further noted here that in order to avoid obscuring the present disclosure with unnecessary details, the attached drawings only show processing steps and / or equipment structures closely related to at least the technical solutions of the present disclosure, and other details that are not significantly related to the present disclosure are omitted.
[0021] Vehicle-to-vehicle (V2V) communication is one of the most promising drivers of intelligent transportation systems, among which latency and reliability are the main focus. In a vehicle-to-vehicle (V2V) communication scenario, several vehicles with common interests on the road can cooperate to form a platoon-based driving mode, in which adjacent vehicles are relatively close and keep a nearly constant distance. Generally, vehicles in a communication system line up in a row or a line to form a platoon. A platoon generally has one leading vehicle and multiple following vehicles, among which the distances between different following vehicles and the leading vehicle are different. Meanwhile, under normal driving conditions, the distances between the following vehicles are relatively close and nearly constant. In a platoon application scenario, the leading vehicle transmits corresponding data to each of all following vehicles through a multicast communication manner, and these data may be the same or different. When applying millimeter wave communication technology, the leading vehicle uses a highly directional beam to perform multicast. Furthermore, to protect data privacy, the communication range only needs to include the leading vehicle and the last following vehicle in the platoon, and is generally a line-of-sight propagation mode. In such a mode, less energy is required for the leading vehicle to reach the communication range that can be covered by using an omnidirectional antenna. For example, applications that consider information sharing in autonomous driving (whether semi-autonomous or fully autonomous). In these applications, the platoon needs to share high-resolution perception data, and generally, the leading vehicle transmits its perception data (obtained by on-board cameras or radar) to the following vehicles by multicast using a highly directional beam. Compared to independent driving, such a platoon-based driving mode has been proven to significantly improve road capacity and energy efficiency.
[0022] It should be noted that the above-mentioned vehicle fleet in which the vehicles are arranged in rows or columns is merely exemplary. In a specific application, the vehicle fleet may have other vehicle arrangement methods, such as vehicles of the fleet being arranged along a specific trajectory, and the vehicles may travel in cooperation (e.g., forming a fleet) and use multicast to communicate data between the vehicles (e.g., between the leading vehicle and the following vehicles).
[0023] However, in application scenarios, some influencing factors / events often occur, resulting in the following vehicles being unable to successfully receive data from the leading vehicle, degrading the communication quality in the platoon. Such events may be related to the relative positions between the vehicles in the platoon not matching the coverage range of the directional beam, the presence of obstructions, etc. For example, in V2V communication scenarios, the leading vehicle generally utilizes a highly directional beam to perform multicasting. However, as the length, shape, and surrounding environment of the platoon are constantly changing, these may degrade the communication quality between the leading vehicle and the following vehicles. The following describes some typical scenarios / events with examples.
[0024] Event 1: The convoy is too long. Generally, when applying millimeter wave communication technology, the leading vehicle in a convoy uses a highly directional beam to perform multicast communication, and the communication range only needs to include from the leading vehicle to the last following vehicle in the convoy, generally using a line-of-sight propagation method.
[0025] However, for example, if the vehicle group becomes too long while traveling due to the distance between vehicles increasing or the addition of new vehicles, the length of the vehicle group at that time may exceed the communication range setting of the previous vehicle group, and the vehicles that have exceeded the previous vehicle group length may not be able to accurately receive data from the lead vehicle, and ultimately may not be able to receive data successfully, which may result in a deterioration of communication quality within the vehicle group.
[0026] Event 2: Some vehicles in the procession are not covered by the beam. Generally, when applying millimeter wave communication technology, the leading vehicle in a convoy uses a highly directional beam to perform multicast communication. Also, during communication, the leading vehicle may dynamically adjust the range covered by the beam to protect the privacy of data. In this way, the vehicles covered by the beam can successfully receive data. However, since the range covered by the communication beam is limited, even if the leading vehicle constantly increases its power, the vehicles not covered by the beam cannot successfully receive data.
[0027] Event 3: The communication link between the lead vehicle and some of the vehicles in the queue is interrupted. Generally, when applying millimeter wave communication technology, the leading vehicle in a convoy uses a highly directional beam to perform multicast communication. However, if there is a shield or obstacle between the leading vehicle and the following vehicles, and the shield or obstacle partially or completely blocks the transmission path of the highly directional beam used for multicast communication, the direct communication link between the leading vehicle and the following vehicles will be blocked, and the following vehicles may not be able to successfully receive data by receiving the highly directional beam.
[0028] As is evident from the above, in a vehicle group communication scenario, some events may occur, such as events related to the relative positional relationship between the vehicles in the vehicle group not matching the coverage range of the beam (e.g., events 1 and 2 above) or the presence of an obstruction (e.g., event 3 above), which may be due to the relative displacement of the leading vehicle and the following vehicles, the vehicle group turning or being too long, or other events, which may result in the multicast communication performed by the leading vehicle using the highly directional beam not being transmitted accurately and even successfully to the following vehicles, resulting in communication quality not being guaranteed. This is even worse in the case of high frequency band communication. The above describes some typical events that may be encountered in a vehicle group communication scenario, but it should be pointed out that these are merely exemplary. Other similar communication quality not being guaranteed events may also be encountered in a vehicle group communication scenario.
[0029] Therefore, when using multicast communication, how to ensure the communication quality between the leading vehicle and the following vehicles in a vehicle group is an important issue. In addition, in order to realize effective communication management, it is important to find the cause of the deterioration of the communication link quality, in other words, to effectively determine the cause of the deterioration of the communication quality.
[0030] The present disclosure proposes a basic concept for determining a communication situation in a communication scenario and dynamically adjusting the communication arrangement according to the specific communication situation in the communication scenario, thereby making it possible to better adapt the communication arrangement to the communication scenario, thereby eliminating the influence of unfavorable factors and ensuring the communication quality between the leading vehicle and the following vehicles in a vehicle convoy during multicast communication. In particular, the present disclosure proposes a communication situation determination based on the measurement of heterogeneous antennas (a combination of a first-class antenna and a second-class antenna), in which the first-class antenna and the second-class antenna have different directional characteristics. The directional characteristics may in particular relate to the antenna's directional range, angle, etc. Preferably, the second-class antenna has a wider directional characteristic than the first-class antenna, e.g., a wider directional range, a wider directional angle. For example, the directional range of the second-class antenna covers the directional range of the first-class antenna. The present disclosure further proposes to accordingly adjust the communication arrangement, in particular the data communication arrangement via the second-class antenna, based on the determination of the communication situation.
[0031] It should be noted that the first and second antennas can be realized in a number of ways. According to an embodiment, the first and second antennas can be two separate sets of antennas that use different directional ranges to transmit / receive beams for communication. For example, they can be two sets of antennas for directional beam communication and omnidirectional beam communication, respectively. According to an embodiment, the first and second antennas can be the same antennas, but can use different directional ranges to transmit / receive beams for communication at a specific time. For example, they can be antenna arrays that can perform both directional beam communication and omnidirectional beam communication and can be arranged to perform only one of them at a specific time.
[0032] The following description is given by taking the first class of antennas as directional antennas and the second class of antennas as omnidirectional antennas as an example. It should be noted that the following description based on directional antennas and omnidirectional antennas is merely illustrative and not restrictive. As long as the above directional range requirements are met, other types of the first class of antennas and the second class of antennas can also be used to realize the aspects and embodiments of the present disclosure.
[0033] The following describes an embodiment of the present disclosure by taking a vehicle group communication system as an example. In the embodiment of the present disclosure described below, one specific vehicle in the vehicle group system is a local management user and is called a leading vehicle, and other vehicles in the vehicle group system are following vehicles. It is assumed that all vehicles, including the leading vehicle and following vehicles in the vehicle group system, are provided with omnidirectional antennas and directional antennas. Specifically, the present disclosure simultaneously uses omnidirectional antennas and directional antennas arranged on the vehicles, and performs data communication between the leading vehicle and following vehicles using a highly directional beam transmitted via a directional antenna, thereby improving road capacity and energy efficiency. In addition, by using omnidirectional antenna communication between the leading vehicle and following vehicles to more appropriately and accurately determine the communication situation, the type of event that affects the communication via the omnidirectional antenna after the communication via the directional antenna is affected can be determined, and the communication arrangement can be adjusted accordingly. This can improve the communication between the vehicles, and the communication of the vehicle group can be maintained robustly and robustly. The communication via the directional antenna and the communication via the omnidirectional antenna can be performed by various methods known in the art, and will not be described in further detail here.
[0034] It should be noted that, although the factors and events affecting communication in the multicast communication operation in the grouping mode are described using the vehicle group communication mode as an example, similar influencing factors and events may occur in other cooperative operation scenarios having multiple terminal side electronic devices, and similar situations exist in wireless communication scenarios that use multicast using a direct link (side link), such as drone formation flight, intelligent engineering robot cooperative operation, etc. Therefore, the basic technical concept and technical proposal of the present disclosure can be similarly applied to similar wireless communication scenarios using multicast, in which both directional antennas and omnidirectional antennas are used simultaneously to perform multicast communication.
[0035] It should be noted that the term "omnidirectional antenna" is used merely for convenience of description and does not necessarily refer to a known omnidirectional antenna. For example, the omnidirectional antenna may refer to an antenna that is not completely omnidirectional but transmits a beam close to omnidirectional, or even an antenna that has a specific beam coverage range that is smaller than the coverage range of an omnidirectional antenna but larger than the coverage range of a directional antenna, suitable for a specific application scenario. For example, the coverage range of an omnidirectional antenna is not limited to 360 degrees, but may be a smaller angle, for example, a specific angle in a specific direction, such as 240 degrees, or even 180 degrees.
[0036] The basic technical concept and exemplary embodiments of the wireless communication system of the present disclosure will be described below with reference to the accompanying drawings.
[0037] FIG 1A illustrates a schematic diagram of a wireless communication system 100 according to an embodiment of the present disclosure. The wireless communication system 100 may include a transmitting device 130 and terminal side electronic devices 120a, 120b, and 120c. Although three terminal side electronic devices are illustrated in FIG 1A, it should be understood that the wireless communication system 100 may further include any other suitable number of terminal side electronic devices.
[0038] It should be noted that the wireless communication system of the present disclosure can be applied to various wireless communication scenarios that perform multicast using a direct link (side link), such as vehicle group communication, drone formation flight, intelligent engineering robot cooperative operation, etc. For example, each of the sending device 130 and the terminal side electronic devices 120a, 120b, and 120c may further be a vehicle, a drone, a robot, or any other electronic device suitable for performing multicast using a direct link.
[0039] In some embodiments, the wireless communication system 100 may optionally further include a controlling electronics 110. The controlling electronics 110 may be arranged to communicate with the transmitting equipment 130 and the terminal electronics 120a, 120b and 120c by wireless communication technologies, such as 4G, 5G, etc. In this disclosure, "controlling electronics" has its full ordinary meaning and may include equipment that is part of a wireless communication system or radio system, such as, for example, performing communication status determination and / or communication configuration settings.
[0040] In some embodiments, the controlling electronics 110 may be, for example, a base station (e.g., gNB) or a road side unit (RSU), or the like, or a part thereof. In this disclosure, the term "base station" has its full ordinary meaning and includes a wireless communication station that is at least a part of a wireless communication system or a radio system to perform communication. Examples of base stations may be, for example, eNBs conforming to 4G communication standards, gNBs conforming to 5G communication standards, remote radio heads, wireless access points, drone control towers, or communication devices performing similar functions. In some embodiments, the transmitting device 130 and any one of the terminal side electronics 120a, 120b, and 120c may function as the controlling electronics 110 to realize communication situation determination and / or communication configuration setting.
[0041] In order to travel in a coordinated manner, the transmitting device 130 may communicate with the terminal side electronic devices 120a, 120b, and 120c using a multicast based on a direct link. For example, the transmitting device 130 and each of the terminal side electronic devices 120a, 120b, and 120c may be vehicles, among which the transmitting device 130 is a leading vehicle, and each of the terminal side electronic devices 120a, 120b, and 120c is a following vehicle. Since the terminal side electronic devices 120a, 120b, and 120c are arranged in a specific positional relationship, the leading vehicle and the following vehicles that can cooperate to form a traveling mode based on a vehicle group are generally lined up in a line, for example. Therefore, in order to improve transmission efficiency, the transmitting device 130 generally uses a directional antenna to transmit a highly directional beam to perform multicast. In order for vehicles to share data while driving in cooperation with each other, the transmitting device 130 transmits sensory data acquired by the transmitting device 130 (for example, data acquired by a camera or radar mounted on the transmitting device 130) to the terminal side electronic devices 120a, 120b, and 120c by a method called multicast using a direct link.
[0042] The transmitting device 130 and the terminal side electronic devices 120a, 120b and 120c may be respectively provided with directional antennas and omnidirectional antennas. It should be understood that the directional antennas and omnidirectional antennas here are merely examples of a first class of antennas and a second class of antennas having different directional ranges. The directional antennas and omnidirectional antennas may be two sets of antennas for performing directional beam communication and omnidirectional beam communication, respectively, and may alternatively be an antenna array capable of performing both directional beam communication and omnidirectional beam communication, and may be arranged to perform only one of them at a particular time.
[0043] However, while the device is moving, the communication quality of the multicast between the transmitting device and the terminal side electronic device may deteriorate due to changes in the position of the terminal side electronic device, changes in the surrounding environment, and even the addition of a new terminal side electronic device. Therefore, the present disclosure proposes a technical concept that detects the communication situation and adjusts the communication arrangement accordingly to deal with the deterioration of communication quality. An embodiment according to the present disclosure will be described below.
[0044] It should be noted that, although the drawings show the transmitting device and the terminal side electronics arranged in a row, and the transmitting device located at the top of the row, this is merely exemplary. The transmitting device may be located at other positions in the row, such as at the end of the row, or at other specific positions other than the end of the row. It should be noted that, although the drawings show the terminal side electronics 120a, 120b, and 120c generally arranged in a row, this is merely exemplary. The terminal side electronics may be arranged in other suitable arrangements / layouts, as long as the terminal side electronics can operate in cooperation with each other and utilize directional beams to perform multicast communication. Thus, the technical concept of the present disclosure is equally applicable to such cases.
[0045] FIG. 1B illustrates an example signaling interaction flow diagram associated with communication in a wireless communication system according to an embodiment of the present disclosure.
[0046] In S101, the terminal side electronic device acquires information regarding the state of communication between the transmitter device and the terminal side electronic device via a directional antenna.
[0047] As an example, the communication status via the directional antenna may be continuously / periodically acquired by the terminal side electronic device, or may be acquired in response to a change in the data communication status. As another example, the terminal side electronic device may acquire the communication status via the directional antenna between the terminal side electronic device and the transmitting device upon receiving a command / request from the control side electronic device.
[0048] As an example, the related information may be a related parameter itself indicating the communication status (e.g., raw data indicating the communication status). In this way, the controlling electronic device can accurately judge the communication status based on the received parameter information. Or, in order to save communication resources, the related information may be a quantized value of the related parameter (e.g., a value obtained by quantizing raw data with a certain threshold). As another example, the related information may further be a judgment result of the communication status, or a command or request based on the judgment result, which may be sent to the controlling electronic device to further save the work overhead of the controlling electronic device.
[0049] In S102, the terminal side electronic device transmits the acquired related information to the control side electronic device. For example, the terminal side electronic device may transmit the acquired related information every time it acquires the related information. Additionally or alternatively, the terminal side electronic device may transmit the acquired related information only under a specific communication condition. For example, the information may be transmitted only when the communication condition becomes poor. In this way, less information is transmitted, transmission resources are saved, and transmission efficiency is improved.
[0050] In S103, in order to obtain the communication status between the terminal side electronic device and the transmitting device via the omnidirectional antenna, the control side electronic device instructs the transmitting device to communicate with the terminal side electronic device via the omnidirectional antenna based on the received information.
[0051] As an example, the control electronic device may determine the communication status of the directional antenna based on the acquired related information (e.g., raw data or quantized value), and instruct the transmitting device to perform omnidirectional antenna communication only when the communication status of a specific directional antenna (e.g., when the communication status becomes poor) is met. As another example, when the related information is to be transmitted only when the communication status of a specific directional antenna is met, the control electronic device may instruct the transmitting device to perform omnidirectional antenna communication each time the related information is received. For example, when the related information is to be transmitted only when the communication status is poor, the control electronic device may instruct the transmitting device to perform omnidirectional antenna communication upon receiving the transmitted information. This can reduce the workload of the control electronic device.
[0052] In S104, the transmitting device transmits a reference signal to the terminal side electronic device via the omnidirectional antenna, and in S105, based on the received reference signal, the terminal side electronic device acquires information regarding the communication status via the omnidirectional antenna between the terminal side electronic device and the transmitting device, and in S106, the terminal side electronic device transmits the acquired information regarding the communication status via the omnidirectional antenna to the control side electronic device.
[0053] For example, similar to the information regarding the communication status via a directional antenna described above, the information regarding the communication status via an omnidirectional antenna may be a relevant parameter indicating the communication status itself or a quantized value thereof, or may even be a judgment result of the communication status.
[0054] In S107, the control electronic device may set the communication arrangement between the transmitting device and the terminal device based on the acquired information on the communication situation via the omnidirectional antenna. For example, the control electronic device may determine what factors the communication situation is affected by (or what event it belongs to) based on the related information, and adjust the communication arrangement accordingly based on the determination result. Thereby, the communication quality between the transmitting device and the terminal device is improved.
[0055] According to an embodiment, the communication arrangement between the terminal side electronic device and the transmitting device may refer to a communication arrangement for performing data communication between the terminal side electronic device and the transmitting device. Preferably, this communication arrangement refers to an arrangement for directional antenna communication between the terminal side electronic device and the transmitting device, such as the transmission power, beam radiation angle and range (corresponding to the directivity and coverage range of the transmission beam) of the directional antenna of the transmitting device, the receiving arrangement of the terminal side electronic device, etc. Alternatively, this communication arrangement may further refer to other communication arrangements for data communication, such as at least one of the mark and the arrangement of the relay device available for data communication (it should be noted that if the arrangement information of the relay device and the mark are stored in correspondence with each other, the arrangement parameters of the relay device can be directly known by knowing the mark of the relay device, and in this case, only the mark needs to be transmitted, and there is no need to transmit the arrangement information), etc. As an example, the communication arrangement may further be set according to the positions of the terminal side electronic device and the transmitting device, information detected by the camera or radar of the transmitting device and / or the terminal side electronic device (e.g., environmental information, etc.), etc.
[0056] As a result, in the wireless communication system, the transmitting device and the terminal side electronic device can communicate based on the adjusted communication arrangement. In this way, the influence of the previous unfavorable factors can be effectively eliminated and the communication quality can be improved. As an example, the adjusted communication arrangement may be transmitted to both the transmitting device and the terminal side electronic device. The transmitting device can communicate based on the adjusted communication arrangement. The terminal side electronic device can perform appropriate reception by appropriately adjusting the reception arrangement prior to reception. As another example, the adjusted communication arrangement may be transmitted to the transmitting device. The transmitting device can communicate based on the adjusted communication arrangement. The terminal side electronic device can perform appropriate data communication by determining its own reception arrangement by a technique known in the art when receiving. It should be noted that the adjusted communication arrangement may be transmitted via any suitable communication link between the control side electronic device and the transmitting device / terminating side electronic device, which may be a 4G link, a 5G link, or other links in the art, and will not be described in further detail here.
[0057] According to one embodiment, the control electronic device may be, for example, a base station (e.g., a gNB) or a road side unit (RSU) or the like or part thereof, and can instruct the transmitting equipment and the terminal side electronic device to perform operations by communicating with the transmitting equipment and the terminal side electronic device via a communication method known in the art.
[0058] According to another embodiment, the control electronic device may be the terminal electronic device itself. In this case, the communication status via the directional antenna is determined by the terminal electronic device to inform the transmitting device to perform omnidirectional antenna communication. And the communication status via the omnidirectional antenna is determined by the terminal electronic device to set the communication configuration and inform the transmitting device of the set communication configuration. It should be noted that the set communication configuration may be transmitted to the transmitting device, for example, via the omnidirectional antenna or other suitable link.
[0059] According to another embodiment, the control side electronic device may be the transmitting device itself. In this case, the transmitting device may instruct the terminal side electronic device to obtain information on the communication situation (including information on the communication situation via the directional antenna and information on the communication situation via the omnidirectional antenna) and notify the transmitting device (for example, by transmitting a reference signal) so that the transmitting device judges the communication situation. Alternatively, the transmitting device may directly obtain the communication situation based on feedback from the terminal side electronic device so that the transmitting device judges the communication situation. Thereby, the transmitting device can perform the communication configuration setting based on the judgment of the communication situation. It should be noted that, if the communication configuration needs to be transmitted to the terminal side electronic device, it may be transmitted to the terminal side electronic device via, for example, an omnidirectional antenna or other suitable link. Of course, the communication configuration does not have to be transmitted to the terminal side electronic device.
[0060] It should be noted that the controlling electronic device in each operation step in the signaling may be the same electronic device or different electronic devices. For example, the controlling electronic device in each operation step may be the same controlling electronic device, sending electronic device or terminal electronic device. As another example, each operation step may be performed by a different controlling electronic device, sending electronic device or terminal electronic device.
[0061] According to an embodiment of the present disclosure, by determining the communication status between a transmitting device and a terminal side electronic device in a wireless communication system and dynamically adjusting the communication arrangement according to the communication status, it is possible to further improve resource utilization efficiency and ensure communication quality.
[0062] Hereinafter, an electronic device and a communication method in a wireless communication system that performs multicast using a direct link according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.
[0063] FIG. 2 shows a schematic block diagram of a terminal side electronic device 200 according to an embodiment of the present disclosure. The terminal side electronic device 200 may correspond to the terminal side electronic device 120a, 120b or 120c in FIG. 1A, and can communicate with a control side electronic device / transmitter device in a wireless communication system. For clarity, the following will be described by taking the case where the first type of antenna is a directional antenna and the second type of antenna is an omnidirectional antenna as an example. As shown in FIG. 2, the terminal side electronic device 200 may include a directional antenna 210, an omnidirectional antenna 220 and a processing circuit 230.
[0064] According to an embodiment of the present disclosure, the processing circuit 230 may be configured to acquire first information indicating a communication status between the terminal side electronic device 200 and the transmitting device via a directional antenna, and to acquire second information indicating a communication status between the terminal side electronic device 200 and the transmitting device via an omnidirectional antenna, wherein communication between the terminal side electronic device 200 and the transmitting device via the omnidirectional antenna is performed based on the first information, and a communication arrangement between the terminal side electronic device 200 and the transmitting device can be set based on at least the second information.
[0065] In the above example of the device configuration, the processing circuit 230 may be in the form of a general-purpose processor, or may be a dedicated processing circuit such as an ASIC. For example, the processing circuit 230 may be configured by a circuit (hardware) or a central processing unit (e.g., a central processing unit (CPU)). In addition, the processing circuit 230 may be loaded with a program (software) for operating the circuit (hardware) or the central processing unit. This program may be stored in a memory (e.g., located in a memory) or an external storage medium connected from the outside, or may be downloaded via a network (e.g., the Internet).
[0066] According to an embodiment of the present disclosure, the processing circuit 230 may include each unit for realizing the above functions, for example, a directional antenna communication status acquisition unit 232 arranged to acquire first information indicating a communication status via a directional antenna between the terminal side electronic device 200 and the transmitting device, and an omnidirectional antenna communication status acquisition unit 234 arranged to acquire second information indicating a communication status via an omnidirectional antenna between the terminal side electronic device 200 and the transmitting device.
[0067] Optionally, the processing circuit 230 may include a communication arrangement setting unit 236 arranged to set a communication arrangement between the terminal electronic device 200 and the sending device based on the second information. The communication arrangement setting unit 236 is drawn with a dotted line, which is intended to illustrate that this unit is not necessarily included in the processing circuit. As an example, this unit may be located in the terminal electronic device but outside the processing circuit, or even outside the terminal electronic device 200.
[0068] These units included in processing circuit 230 may be communicatively coupled to each other (not shown) and / or to one or more of directional antenna 210 and omni-directional antenna 220 (not shown). It should be noted that although each unit is shown in FIG. 2 as a separate unit, one or more of these units may be integrated into one unit or split into multiple units.
[0069] It should be noted that each of the above units is merely a logic module divided based on the specific functions they realize, and does not limit the specific implementation manner, and may be realized, for example, in the form of software, hardware, or a combination of software and hardware. When actually realized, each of the above units may be realized as an independent physical entity, or may be realized by a single entity (e.g., a processor (e.g., CPU or DSP), integrated circuit, etc.). In addition, the dashed lines in the figures indicate that each of the above units does not actually exist, and the operations / functions realized by each of the units may be realized by the processing circuit itself.
[0070] It should be noted that the directional antenna 210 and the omnidirectional antenna 220 are merely examples of a first class of antennas and a second class of antennas having different directional ranges. According to an embodiment, the directional antenna 210 and the omnidirectional antenna 220 may be two sets of antennas or antenna arrays performing directional and omnidirectional beam communication, respectively, or may be one set of antenna arrays that can be configured to perform both directional and omnidirectional beam communication but only one at different times. As an example, the antennas 210, 220 may be a communication unit or a part of a communication unit. The communication unit can be configured to communicate with a control electronic device, a transmitting device, or other terminal electronic device under the control of the processing circuitry 230. In one example, the communication unit may be realized as a transmitter or transceiver including communication components such as an antenna array (e.g., both omnidirectional and directional antennas, or a single antenna array that can realize the functions of both omnidirectional and directional antennas) and / or a radio frequency link. In one embodiment, the communication unit may transmit information regarding the communication situation determined in the processing circuitry to the control electronic device. In one embodiment, the communication unit may send and receive signaling necessary for the processes described in the embodiments of the present disclosure.
[0071] 2 shows the processing circuit 230 as being separate from the antennas 210, 220, the processing circuit 230 may also be implemented to include the antennas. Furthermore, the processing circuit 230 may also be implemented to include one or more other components in the terminal electronics, or may be implemented as the terminal electronics. When actually implemented, the processing circuit 230 may be implemented as a chip (e.g., an integrated circuit module including a single chip), a hardware component, or a complete product.
[0072] It should be noted that although FIG. 2 shows antennas 210, 220 as being included in electronic device 200, antennas 210, 220 may be antennas that are not included in electronic device 200 but are coupled / attached to electronic device 200.
[0073] It should be understood that FIG. 2 is merely a schematic structural arrangement of the terminal side electronic device. The terminal side electronic device 200 may further include other possible components (e.g., memory, etc.). Optionally, the control side electronic device 200 may further include other components not shown, such as a memory, a radio frequency link, a baseband processing unit, a network interface, a controller, etc. The processing circuit may be associated with the memory and / or an antenna. For example, the processing circuit may be directly or indirectly connected to the memory (e.g., other components may be connected in between) to access data. Also, for example, the processing circuit may be directly or indirectly connected to the antenna. Thereby, a radio signal is transmitted via the communication unit, and a radio signal is received via the communication unit.
[0074] The memory can store various information generated by the processing circuit 230 (e.g., information about communication conditions, arrangement information of the terminal electronic device, location information, etc.), programs and data used to operate the control electronic device, data transmitted by the terminal electronic device, etc. The memory may be located in the terminal electronic device but outside the processing circuit, or even outside the terminal electronic device. The memory may be volatile and / or non-volatile. For example, the memory may include, but is not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read only memory (ROM), and flash memory.
[0075] The functions of the units in the processing circuit 230 of the terminal side electronic device 200 in FIG. 2 will be specifically described below.
[0076] According to an embodiment of the present disclosure, the first information indicating the communication status between the terminal side electronic device 200 and the transmitting device via the first type antenna may be generated by the terminal side electronic device 200. For example, the first type antenna may be a directional antenna. In one embodiment, the first information may be acquired by the directional antenna communication status acquisition unit 232. According to an embodiment of the present disclosure, the first information may include any one of communication quality information of data communication between the terminal side electronic device 200 and the transmitting device via a first type antenna, and channel quality information determined based on a reference signal transmitted from the transmitting device via a first type antenna, or a quantized value thereof. Among them, the channel quality information may include any one of power parameters (e.g., reference signal received power (RSRP) and reference signal received quality (RSRQ)) of the reference signal transmitted from the transmitting device via the first type antenna, and a channel state (e.g., channel quality indicator (CQI)) between the terminal side electronic device 200 and the transmitting device via the first type antenna estimated based on the received reference signal.
[0077] According to an embodiment of the present disclosure, the first information may refer to information indicating the communication conditions via the first type antenna (e.g., parameters related to the communication conditions such as raw data indicating the communication conditions) itself, such as various parameters related to data communication quality, various parameters related to channel quality via the first type antenna, etc.
[0078] Alternatively or additionally, the first information may be a quantized value of information indicating the communication status, for example, a simplified quantized value indicating the communication status obtained from the information. According to an embodiment, in order to reduce the number of bits required for information transmission, the information may be normalized to obtain a normalized value as the quantized value, or the information may be quantized by employing various quantization methods in the art.
[0079] According to another embodiment, a threshold value (e.g., a limit threshold value) for the communication situation may be set and this information may be processed to determine which rank of communication situation the acquired communication situation belongs to, and the determination result may be directly acquired and used as the first information. As an example, the communication situation may be represented by a corresponding rank value, and this rank value may be transmitted as the first information. For example, it is assumed that the communication situation is divided into ranks 1 to N, and the rank value N corresponding to the acquired communication situation is transmitted as the first information. In this case, this rank value may be regarded as a kind of quantized value.
[0080] According to another embodiment, the first information may be a value directly indicating the superiority or inferiority of the communication situation, and may be indicated, for example, by a binary bit. For example, the superiority or inferiority of the communication situation is indicated by determining whether the communication situation exceeds a specific threshold. Among them, 1 indicates that the communication situation is good, exceeds a specific threshold, and can be maintained, and 0 indicates that the communication situation is bad, falls below a specific threshold, and needs to be adjusted. In this way, the number of bits required for transmitting the first information can be further reduced, and the transmission efficiency is further improved. In this case, the specific threshold may be regarded as a quantization threshold for quantizing the information on the communication situation, and the binary bit may be regarded as a kind of quantization value and is transmitted as the first information.
[0081] According to an embodiment of the present disclosure, the first information may be acquired continuously or periodically by the terminal side electronic device, and alternatively or additionally, may be acquired in response to a specific trigger (e.g., a specific reference signal transmitted from the transmitting device).
[0082] According to an embodiment of the present disclosure, the first information may be transmitted to the control electronic device / transmitter device when it is acquired by the terminal electronic device. The control electronic device / transmitter device can then determine the communication status based on the first information and determine whether to perform the second type of antenna communication based on the first information. In this manner, the control electronic device / transmitter device can determine whether to perform the second type of antenna communication based on the communication status parameter itself or its quantized value (e.g., a communication status rank value, a binarized value indicating the superiority or inferiority of the communication status, etc.) indicated by the first information.
[0083] Alternatively or additionally, the terminal side electronic device may transmit the first information (preferably a quantized value or a binary value) or specific command / instruction information to the control side electronic device / transmission device only when the terminal side electronic device judges that the communication situation is poor based on the first information. After the control side electronic device / transmission device receives the first information or the specific command / instruction information, the control side electronic device / transmission device may directly perform the second type of antenna communication without making a judgment. This can reduce the processing overhead of the control side electronic device / transmission device.
[0084] According to an embodiment, the specific command / instruction information may be information indicating the superiority or inferiority of the communication situation via the first type antenna. According to one example, when the terminal side electronic device determines that the communication situation is poor, the terminal side electronic device may transmit any one-bit command information to the control side electronic device / transmitter device to notify the control side electronic device / transmitter device that the second type antenna communication can be performed. The command information transmitted at this time may be equivalent to the first information. When the control side electronic device / transmitter device receives the command information in this way, it can perform the second type antenna communication.
[0085] According to an embodiment, the terminal side electronic device may transmit the first information to the control side electronic device / transmitter device only when the terminal side electronic device judges that the communication situation is poor based on the first information. The control side electronic device / transmitter device may verify whether the judgment of the terminal side electronic device is correct or not by making a judgment based on the received first information. This can further improve the accuracy of the judgment of the communication situation.
[0086] According to an embodiment of the present disclosure, the terminating electronic device may transmit the first information directly to the transmitting or controlling electronic device, for example, via a first type of antenna, if there is still a direct link between the terminating electronic device and the transmitting or controlling electronic device, or the terminal electronic device may transmit the first information to the transmitting or controlling electronic device via another device, for example, via a relay device or another auxiliary communication device.
[0087] According to an embodiment, the first information may be data communication quality information or a quantized value thereof, and may be periodically or continuously acquired by the terminal side electronic device. In this case, the terminal side electronic device may acquire the communication quality information or the quantized value thereof as the first information when performing data communication with the transmitting device via a first type antenna.
[0088] According to another embodiment, the first information may be channel quality information or a quantized value thereof. In this case, the terminal side electronic device may perform channel quality estimation based on a first reference signal transmitted from the transmitting device via a first type antenna, and obtain the channel quality information or the quantized value thereof as the first information.
[0089] According to an embodiment, obtaining the first information indicating the communication status between the terminal side electronic device 200 and the transmitting device via the first type antenna includes determining the data communication quality between the terminal side electronic device 200 and the transmitting device via the first type antenna, and determining the first information based on the first reference signal received from the transmitting device via the first type antenna in response to the data communication quality between the terminal side electronic device 200 and the transmitting device via the first type antenna falling below a corresponding threshold. This allows the terminal side electronic device to estimate the channel quality based on the received first reference signal and obtain the information on the channel quality as the first information. The first information can be determined by any suitable channel quality estimation technique. As an example, the first information may be transmitted to the controlling electronic device / transmitting device as described above.
[0090] According to the embodiments of the present disclosure, the first reference signal may be transmitted by the transmitting device via the first type of antenna in various manners, in particular, the first reference signal may be transmitted by the transmitting device spontaneously and / or in response to a request or command by the transmitting device.
[0091] According to one embodiment, the first reference signal is continuously transmitted by the transmitting device via its first type of antenna or periodically (e.g., at regular intervals), which may be referred to as being transmitted autonomously by the transmitting device.
[0092] According to another embodiment, the transmitting device may transmit the first reference signal depending on the quality of data communication between the transmitting device and the terminal device via the first type antenna. For example, the transmitting device may determine the data communication status between the transmitting device and the terminal device via the first type antenna, and transmit the first reference signal based on the determination result. Such a case may also be called the first reference signal being transmitted by the transmitting device.
[0093] According to an embodiment of the present disclosure, the transmitting device may make the determination based on information on the quality of data communication via the first type of antenna from the terminal side device, or feedback on the data communication from the terminal device.
[0094] In another embodiment, the terminal side electronic device 200 may transmit data communication quality information (e.g., bit error rate, accuracy rate, etc.) to the transmitting device via a first type antenna between the terminal side electronic device 200 and the transmitting device, and this transmission may be performed periodically or in response to the data communication quality information falling below a corresponding threshold, and the data communication quality information may be transmitted directly or relayed by a control side electronic device or the like. Among them, the transmitting device compares the received data communication quality information with a specific threshold, and when the data communication quality information falls below the corresponding threshold, transmits a first reference signal via a first type antenna (e.g., a directional antenna 210) of the transmitting device.
[0095] In yet another embodiment, the terminal side electronic device 200 may periodically transmit feedback on the data communication quality to the transmitting device. The transmitting device may also transmit a first reference signal in response to the received data communication quality feedback. For example, the terminal side electronic device may determine whether the data communication quality has fallen below a specific threshold and transmit the determination result as feedback to the transmitting device. The transmitting device transmits the first reference signal when the data communication quality feedback is a specific value indicating that the data communication quality is poor. For example, the feedback may be represented by binary data, with a specific value of 1 indicating good and a specific value of 0 indicating bad.
[0096] In one embodiment, when the quality of the data communication between the terminal side electronic device 200 and the transmitting device via a first type antenna is poor, due to packet loss or the like, the transmitting device may not receive the feedback transmitted from the terminal side electronic device 200. In this embodiment, the first reference signal may be transmitted via a first type antenna (e.g., a directional antenna 210) of the transmitting device in response to the transmitting device not receiving feedback on the data communication quality from the terminal side electronic device 200 within a certain time.
[0097] In one embodiment, the first reference signal may be transmitted by the transmitting device in response to a request / command from the terminal side electronic device 200 and / or the controlling side electronic device. This request / command may be transmitted by the terminal side electronic device 200 via the first type antenna (e.g., the directional antenna 210) of the terminal side electronic device 200 and / or transmitted by the controlling side electronic device when the data communication quality via the first type antenna between the terminal side electronic device 200 and the transmitting device falls below a corresponding threshold. For example, when the data communication quality via the first type antenna between the terminal side electronic device 200 and the transmitting device deteriorates to a certain degree (e.g., the bit error rate exceeds a certain threshold or the terminal side electronic device 200 has not received data transmitted from the transmitting device via the first type antenna for a predetermined time), this request / command may be transmitted directly or relayed by the controlling side electronic device (e.g., a base station or a roadside unit, etc.) to the transmitting device.
[0098] In one embodiment, communication between the terminal side electronic device 200 and the transmitting device via a second type antenna may be performed based on, for example, first information indicating the communication status between the terminal side electronic device 200 and the transmitting device via a first type antenna acquired by the directional antenna communication status acquisition unit 232.
[0099] Here, the first type antenna and the second type antenna may have different directional characteristics. For example, the second type antenna may have a wider directional characteristic, for example, a wider directional range, a wider directional angle, than the first type antenna. For example, the first type antenna may be a directional antenna, and the second type antenna may be an omnidirectional antenna. According to the embodiment, the antenna of the terminal side electronic device 200 and the antenna of the transmitting device may be realized by the same or similar method. In particular, according to the embodiment, the first type antenna of the terminal side electronic device 200 and the first type antenna of the transmitting device may be the same type of antenna (for example, a directional antenna), and their characteristics (for example, directional range) may be the same or different. The second type antenna of the terminal side electronic device 200 and the second type antenna of the transmitting device are similar.
[0100] According to the embodiment, the antenna of the terminal side electronic device 200 and the antenna of the transmitting device may be realized in different ways as long as they meet the requirements of the directivity range. For example, one of the antenna of the terminal side electronic device 200 and the antenna of the transmitting device may be a single antenna array with different working states, and the other may be two sets of separated antennas.
[0101] According to an embodiment, in response to the first information being below the first threshold or the comparison result of the first information with the first threshold being a specific value, the transmitting device performs communication between the terminal side electronic device 200 and the transmitting device via the second type antenna. For example, if the first information is below the first threshold (e.g., RSRP is below -140 dBm) or the comparison result of the first information with the first threshold is a specific value (e.g., the comparison result of RSRP with the first threshold -140 dBm is a negative value, i.e., RSRP is below -140 dBm or the comparison result is 0 when 1 represents greater than or equal and 0 represents less than), the transmitting device performs communication between the terminal side electronic device 200 and the transmitting device via the second type antenna. The first threshold may be set according to the communication request, the type of the first information, etc.
[0102] According to one embodiment, communication via the second type of antenna may occur proactively by the transmitting device and / or in response to a request or command by the transmitting device.
[0103] According to one embodiment, the transmitting device may determine the received first information and perform a second type of antenna communication based on the determination result, which may be referred to as being performed autonomously.
[0104] According to an embodiment, when the first information is a binary value indicating the quality of data communication, such as the above-mentioned feedback of data communication quality, the transmitting device may perform communication via the second type of antenna in response to whether the first information is a specific value or not. For example, the transmitting device performs the second type of antenna communication only when the first information is 0. It should be noted that the judgment operation regarding the first information may be performed in other manners, such as the above-mentioned manner.
[0105] According to an embodiment, the transmitting device may perform communication via the second type antenna in response to a request / command from the terminal side electronic device / control side electronic device. The terminal side electronic device may transmit the first information or command information to the transmitting device as this request / command only when the data communication quality is poor. When the transmitting device receives information, e.g., request or command information, via the first type antenna from the terminal side electronic device / control side electronic device, it may directly perform communication via the second type antenna without verifying the first information. As another example, the transmitting device may further still determine the first information when a request / command is received. This can further improve the accuracy of determining the communication situation.
[0106] Additionally, in one embodiment, in response to the change between the current first information and the previous first information being within a predetermined range (e.g., the absolute value of the difference between the current RSRQ and the previous RSRQ is less than 5), the transmitting device may perform communication between the terminal electronic device 200 and the transmitting device via the second type antenna, either spontaneously or upon command from the controlling electronic device. This spontaneous or command-based communication may be performed in the manner described above and will not be described in further detail here.
[0107] By comparing the current first information with the previous first information, it is possible to determine whether a steady change has occurred in the communication situation via the first type antenna, thereby avoiding the ping-pong phenomenon caused by a sudden change or a false report due to a measurement error, and the waste of communication resources due to frequent adjustment of the communication configuration.
[0108] According to an embodiment of the present disclosure, in response to the communication through the second type antenna performed by the transmitting device, the terminal side electronic device 200 may acquire the second information, and information related to the second information, such as the second information itself or the quantization result of the second information, is transmitted to the transmitting device and / or the control side electronic device. In one embodiment, the second information may be acquired by the omnidirectional antenna communication status acquisition unit 234.
[0109] According to an embodiment, the second information may indicate a communication status between the terminal side electronic device 200 and the transmitting device via a second type antenna. This second information may include channel quality information via the second type antenna between the terminal side electronic device 200 and the transmitting device or a quantized value thereof, such as RSRP, RSRQ, CQI, etc. For example, the second information may be the channel quality information via the second type antenna itself or a quantized value thereof, and this quantized value may be obtained by a method similar to the quantization method of the first information described above, which will not be described in further detail here.
[0110] The channel quality information via the second type of antenna may be estimated by various methods known in the art. According to one embodiment, the second information may be determined based on a second reference signal transmitted from the transmitting device via the second type of antenna. By way of example, the second information may be determined by channel quality estimation based on the second reference signal, and any suitable channel quality estimation technique may be employed.
[0111] According to one embodiment, acquiring second information indicating a communication status between the terminal side electronic device and the transmitting device via a second type antenna may include determining the second information based on a second reference signal transmitted from the received transmitting device via the second type antenna in response to the first information falling below a first threshold or a comparison result between the first information and the first threshold being a specific value.
[0112] According to embodiments of the present disclosure, the second reference signal may be transmitted by the transmitting device in various suitable manners. For example, as described above, the second reference signal may be transmitted by the transmitting device spontaneously or in response to a request / command.
[0113] In one embodiment, the second reference signal may be transmitted by the transmitting device through a second type antenna (e.g., the omnidirectional antenna 220) of the transmitting device in response to a request from the terminal side electronic device 200. Wherein, the request may be transmitted by the terminal side electronic device 200 through the second type antenna (e.g., the omnidirectional antenna 220) of the terminal side electronic device 200 when the first information is below a first threshold or the comparison result between the first information and the first threshold is a certain value.
[0114] In another embodiment, the terminal side electronic device 200 may transmit the first information or a comparison result between the first information and a first threshold to the transmitting device or the controlling side electronic device. The second reference signal may be transmitted by the transmitting device via a second type of antenna (e.g., the omnidirectional antenna 220) of the transmitting device in response to the received first information being below the first threshold or the comparison result between the received first information and the first threshold being a certain value.
[0115] It should be understood that the second type antenna of the terminal side electronic device 200 and the second type antenna of the transmitting device may be the same type of antenna (e.g., an omnidirectional antenna), but their characteristics (e.g., directional range) may be the same or different.
[0116] In another embodiment, the transmitting device may further transmit a second reference signal in response to an instruction from the controlling electronic device, and the instruction may be transmitted by the controlling electronic device based on information regarding the communication status of the first type of antenna communication between the transmitting device and the controlling electronic device.
[0117] According to an embodiment of the present disclosure, the communication arrangement between the terminal side electronic device 200 and the transmitting device may be set based on at least the second information. According to an embodiment, in order to further improve the communication quality between the terminal side electronic device and the transmitting device, the communication arrangement may be appropriately set based on a comparison result between the second information and a specific threshold value. The meaning and setting of the communication arrangement may be as described above, and will not be described in further detail here.
[0118] According to an embodiment of the present disclosure, the communication arrangement may be set / adjusted by various devices. According to an embodiment of the present disclosure, the communication arrangement may be set by the transmitting device based on the second information, may be set by the terminal side electronic device based on the second information and notified to the transmitting device, or may be set by other devices, such as the control side electronic device, auxiliary repeater device, etc., and notified to the transmitting device.
[0119] For example, in order for the control side electronic device / transmitting device to set the communication arrangement between the terminal side electronic device 200 and the transmitting device 400, the terminal side electronic device 200 may transmit any one of the second information and the comparison result between the second information and a specific threshold value to the control side electronic device / transmitting device. For example, the communication arrangement setting unit 236 of the terminal side electronic device 200 may further set the communication arrangement between the terminal side electronic device 200 and the transmitting device 400 based on the second information, and notify the control side electronic device or the transmitting device of the setting information to perform the communication arrangement setting.
[0120] Thus, the transmitting device can perform data communication with the terminal electronic device 200 based on the set / adjusted communication configuration. The terminal electronic device 200 can receive the transmitted data more robustly and reliably, and the communication quality is stable. It should be noted that the terminal electronic device 200 may include a unit for data communication with the transmitting device. Such a unit may be realized by a method known in the art and will not be described in further detail herein.
[0121] 3 shows a flow chart of a method 300 used in a terminal electronic device according to an embodiment of the present disclosure. The following describes the communication method 300 in conjunction with FIG. 2. The terminal electronic device may be, for example, the terminal electronic device 200 shown in FIG.
[0122] In step S310, first information indicating a communication status between the terminal side electronic device 200 and the transmitting device via a first type antenna is acquired. This step S310 may be executed by, for example, the directional antenna communication status acquisition unit 232 in Fig. 2. Various examples of the first information and various implementations for acquiring the first information have already been described, and will not be described further here.
[0123] Then, the process proceeds to step S320. In step S320, second information indicating a communication status between the terminal side electronic device 200 and the transmitting device via a second type antenna is acquired. This step S320 may be executed by, for example, the omnidirectional antenna communication status acquisition unit 234 in FIG. 2. As described above, the communication between the terminal side electronic device 200 and the transmitting device via the second type antenna may be performed based on the first information. Various examples of the second information and various implementations of acquiring the second information have already been described and will not be described further here.
[0124] Then, the process proceeds to step S330. In step S330, a communication arrangement between the terminal side electronic device 200 and the transmitting device may be set based on at least the second information. For example, as described above, the arrangement of the transmitting device for performing data communication via the first type antenna or other arrangements for data communication between the transmitting device and the terminal side device may be adjusted.
[0125] This step S330 may be performed, for example, by the communication arrangement setting unit 236 in Fig. 2. Step S330 is depicted by a dotted line because, as described above, in some embodiments of the present disclosure, the setting of the communication arrangement may also be performed by a device other than the terminal side electronic device 200 (for example, a sending device or a control side electronic device).
[0126] FIG. 4 shows a schematic block diagram of a transmitting device according to an embodiment of the present disclosure. The transmitting device 400 may correspond to the transmitting device 130 in FIG. 1, and can communicate with a control electronic device / terminal electronic device (e.g., the above-mentioned control electronic device 110, terminal electronic devices 120a-120c, 200, etc.) in a wireless communication system. For clarity, the following will be described taking the case where the first type of antenna is a directional antenna and the second type of antenna is an omnidirectional antenna as an example. As shown in FIG. 4, the transmitting device 400 may include a directional antenna 410, an omnidirectional antenna 420, and a processing circuit 430.
[0127] According to an embodiment of the present disclosure, the processing circuit 430 may be arranged to receive first information indicative of a communication status between the terminal side electronic device and the transmitting device 400 via a directional antenna, and based on the first information, to communicate between the terminal side electronic device and the transmitting device 400 via an omnidirectional antenna, and receive second information indicative of a communication status between the terminal side electronic device and the transmitting device 400 via the omnidirectional antenna, wherein a communication configuration between the terminal side electronic device and the transmitting device 400 is configurable based on at least the second information.
[0128] In the above example of the device configuration, the processing circuit 430 may be in the form of a general-purpose processor or a dedicated processing circuit such as an ASIC. For example, the processing circuit 430 may be configured by a circuit (hardware) or a central processing unit (e.g., a central processing unit (CPU)). In addition, the processing circuit 430 may be loaded with a program (software) for operating the circuit (hardware) or the central processing unit. This program may be stored in a memory (e.g., located in a memory) or an external storage medium connected from the outside, or may be downloaded via a network (e.g., the Internet).
[0129] According to an embodiment of the present disclosure, the processing circuit 430 may include each unit for implementing the above-mentioned functions, such as a directional antenna communication status receiving unit 432, an omnidirectional antenna communication initiating unit 434, and an omnidirectional antenna communication status receiving unit 436, and the processing circuit 430 may optionally include a communication arrangement setting unit 438. The communication arrangement setting unit 438 may be located outside the transmitting device 400, and is therefore drawn with a dotted line. These units included in the processing circuit 430 may be communicatively coupled to each other (not shown), and / or may be coupled to one or more of the directional antenna 410 and the omnidirectional antenna 420 (not shown). It should be noted that although each unit is shown as a separate unit in FIG. 4, one or more of these units may be integrated into one unit or divided into multiple units.
[0130] It should be noted that each of the above units is merely a logic module divided based on the specific functions they realize, and does not limit the specific implementation manner, and may be realized, for example, in the form of software, hardware, or a combination of software and hardware. When actually realized, each of the above units may be realized as an independent physical entity, or may be realized by a single entity (e.g., a processor (e.g., CPU or DSP), integrated circuit, etc.). In addition, the dashed lines used to illustrate each of the above units indicate that each of the units does not actually exist, and the operations / functions realized by each of the units may be realized by the processing circuit itself.
[0131] According to an embodiment, the directional antenna 410 and the omnidirectional antenna 420 may be two sets of antennas / antenna arrays performing directional beam communication and omnidirectional beam communication, respectively, or may be one set of antenna arrays that can be arranged to perform both directional beam communication and omnidirectional beam communication. As an example, the antennas 410, 420 may be a communication unit or a part of a communication unit. The communication unit may be arranged to communicate with a control electronic device, a transmitting device, or other terminal electronic device under the control of the processing circuit 430. In one example, the communication unit may be realized as a transmitter or transceiver including communication components such as an antenna array (e.g., both omnidirectional and directional antennas, or a single antenna array that can realize the functions of both omnidirectional and directional antennas) and / or a radio frequency link. In one embodiment, the communication unit may transmit information regarding the communication situation determined in the processing circuit to the control electronic device. In one embodiment, the communication unit may transmit and receive signaling required for the process described in the embodiments of the present disclosure.
[0132] 4, the processing circuit 430 is shown separate from the antennas 410, 420, but the processing circuit 430 may be implemented to include the antennas. Furthermore, the processing circuit 430 may also be implemented to include one or more other components in a transmitting device, or may be implemented as a transmitting device. When actually implemented, the processing circuit 430 may be implemented as a chip (e.g., an integrated circuit module including a single chip), a hardware component, or a complete product.
[0133] It should be noted that although FIG. 4 shows the antennas 410, 420 as being included in the transmitting device 400, the antennas 410, 420 may be antennas that are not included in the transmitting device 400 but are coupled / attached to the transmitting device 400.
[0134] It should be understood that Fig. 4 is merely a schematic structural arrangement of the transmitting device. The transmitting device 400 may further include other possible components (e.g., memory, etc.). Optionally, the transmitting device 400 may further include other components not shown, such as a memory, a radio frequency link, a baseband processing unit, a network interface, a processor, a controller, etc. The processing circuit may be associated with the memory and / or the antenna. For example, the processing circuit may be directly or indirectly connected to the memory (e.g., other components may be connected in between) to access data. Also, for example, the processing circuit may be directly or indirectly connected to the antenna. Thereby, a radio signal is transmitted through the communication unit, and a radio signal is received through the communication unit.
[0135] The memory can store various information generated by the processing circuit 430 (e.g., information about communication conditions, arrangement information of the transmitting device, location information, etc.), programs and data used to operate the transmitting device, data transmitted by the transmitting device, etc. The memory may be located within the transmitting device but outside the processing circuit, or even outside the transmitting device. The memory can be volatile and / or non-volatile. For example, the memory may include, but is not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read only memory (ROM), and flash memory.
[0136] The following specifically describes the functions of the units in the processing circuit 430 of the sending device 400 in FIG.
[0137] According to an embodiment of the present disclosure, the directional antenna communication status receiving unit 432 may be arranged to receive first information indicating a communication status via a directional antenna between the terminal side electronic device 200 and the transmitting device 400. For example, after a radio signal including the first information is received from the terminal side electronic device 200 or the control side electronic device by the directional antenna 410, the first information may be obtained through processing such as down-conversion, analog-to-digital conversion, and then the first information may be transmitted to the directional antenna communication status receiving unit 432.
[0138] In one embodiment, information about a data communication status via a directional antenna between the terminal side electronic device and the transmitting device or a quantized value thereof may be received as the first information. In another embodiment, information about a channel quality status via a directional antenna between the terminal side electronic device and the transmitting device or a quantized value thereof may be received as the first information. Here, the channel quality status may be estimated based on a first reference signal transmitted from the transmitting device. The meaning, type, acquisition and transmission manner, etc. of the first information may be as described above, and will not be described in further detail here.
[0139] It should be noted that, although not shown in the drawings, the processing circuit 430 may include a unit for transmitting a first reference signal, which may transmit the first reference signal continuously, periodically, or in response to the first information. The transmission manner of the first reference signal, etc. may be as described above, and will not be described in further detail here.
[0140] According to an embodiment of the present disclosure, the omni-directional antenna communication initiation unit 434 may be arranged to perform communication via the omni-directional antenna between the terminal side electronic device 200 and the transmitting device 400 based on the first information. For example, the communication via the omni-directional antenna may be performed spontaneously by the transmitting device 400 by determining the first information, and / or may be performed based on a command sent based on the first information from the controlling / terminal side electronic device.
[0141] In one embodiment, the transmitting device 400 may perform communication between the terminal side electronic device 200 and the transmitting device 400 via the omnidirectional antenna in response to the first information being below the first threshold or the comparison result between the first information and the first threshold being a particular value.
[0142] In another embodiment, in response to a change between the current first information and the previously received first information being within a predetermined range, the transmitting device 400 performs communication via an omnidirectional antenna between the terminal side electronic device 200 and the transmitting device 400, either spontaneously or based on a command transmitted based on the first information from the control side electronic device / terminal side electronic device. The meaning, transmission method, etc. of the command transmitted based on the first information may be as described above, and will not be described in further detail here.
[0143] According to an embodiment, the omnidirectional antenna communication initiation unit 434 may transmit a second reference signal through the omnidirectional antenna based on the first information, so as to perform communication between the transmitting device and the terminal side electronic device through the omnidirectional antenna. The manner of transmitting the second reference signal may be spontaneous or in response to a command / request, as described above, and will not be described in further detail here.
[0144] According to an embodiment of the present disclosure, the omnidirectional antenna communication status receiving unit 436 may be arranged to receive second information indicating a communication status between the terminal side electronic device and the transmitting device via the omnidirectional antenna. For example, after a radio signal including the second information is received from the terminal side electronic device 200 or the control side electronic device by the omnidirectional antenna 420, the second information may be obtained by processing such as down-conversion and analog-to-digital conversion, and then the second information may be transmitted to the omnidirectional antenna communication status receiving unit 436. The meaning, type, acquisition and transmission manner, etc. of the second information may be as described above, and will not be described in further detail here.
[0145] According to an embodiment of the present disclosure, a communication arrangement between the terminal side electronic device 200 and the transmitting device 400 may be set based on at least the second information. For example, as described above, the arrangement of the transmitting device for performing data communication via a directional antenna or other arrangements related to data communication between the transmitting device and the terminal side device may be adjusted.
[0146] In one embodiment, the processing circuit 430 may include a communication arrangement setting unit 438, and the communication arrangement setting unit 438 may be configured to set a communication arrangement between the terminal side electronic device 200 and the transmitting device 400 based on at least the second information. It should be understood that the communication arrangement between the terminal side electronic device 200 and the transmitting device 400 may be set by the terminal side electronic device 200 or the controlling electronic device. For example, the transmitting device 400 may transmit any one of the second information and a comparison result between the second information and a certain threshold value to the controlling electronic device / terminal side device, so that the controlling electronic device / terminal side device sets the communication arrangement between the terminal side electronic device 200 and the transmitting device 400.
[0147] Thus, the transmitting device 400 can perform data communication with the terminal side electronic device using the communication configuration after the setting / adjustment, thereby eliminating the influence of adverse factors and maintaining the stability of communication quality. It should be noted that the transmitting device 400 may include a unit for performing data communication with the terminal side electronic device, and such a unit may be realized by a manner known in the art and will not be described in further detail herein.
[0148] FIG. 5 illustrates a flow chart of a communication method 500 for use in a sending device according to an embodiment of the present disclosure.
[0149] In step S510, first information indicating a communication status between the terminal side electronic device and the transmitting device 400 via a first type antenna is received. This first information may be received by the transmitting device 400 from the terminal side electronic device 200 or the control side electronic device, and may be executed by, for example, the directional antenna communication status receiving unit 432 in FIG.
[0150] Then, the process proceeds to step S520. In step S520, the transmitting device 400 can perform communication between the terminal side electronic device 200 and the transmitting device 400 via the second type antenna based on the first information. This step S520 may be executed by, for example, the omnidirectional antenna communication initiation unit 434 in FIG. 4.
[0151] Then, the process proceeds to step S530. In step S530, second information indicating a communication status between the terminal side electronic device 200 and the transmitting device 400 via the second type antenna is received. For example, the second information may be received by the transmitting device 400 from the terminal side electronic device 200 or the control side electronic device. This step S530 may be executed by, for example, the omnidirectional antenna communication status receiving unit 436 in FIG. 4.
[0152] Then, the process proceeds to step S540. In step S540, the sending device 400 may set a communication arrangement between the terminal side electronic device 200 and the sending device 400 based on at least the second information. This step S540 may be performed, for example, by the communication arrangement setting unit 438 in Fig. 4. It should be noted that step S540 is drawn with a dotted line because, in some embodiments, as described above, step S540 may also be performed by a device other than the sending device 400 (for example, the terminal side electronic device 200 or the control side electronic device).
[0153] The following describes an exemplary implementation of communication status determination and communication allocation setting in a wireless communication system according to an embodiment of the present disclosure with reference to the accompanying drawings. In particular, in a wireless communication system, the communication status of a directional antenna and the communication status of an omnidirectional antenna are first determined to accurately determine the influencing factors / events that affect the deterioration of communication quality, and then the communication allocation is appropriately adjusted / set based on the determination result. This can improve the communication quality in the communication system and improve the robustness of communication.
[0154] 6A-6C show three different scenarios in which the communication quality between the terminal side electronic device and the transmitter device via the directional antenna in the wireless communication system according to the embodiment of the present disclosure is degraded. In FIG. 6A-6C, a vehicle-to-vehicle communication system based on a vehicle group is taken as an example for explanation, in which the terminal side electronic device and the transmitter device are both vehicles. It should be understood that, as mentioned above, the present disclosure is not limited thereto, and can be equally applied to scenarios such as unmanned vehicle cooperative flight, intelligent engineering robot cooperative passage, etc.
[0155] Each of the wireless communication systems 600A to 600C shown in FIG. 6A to FIG. 6C may include a leading vehicle 130 and following vehicles 120a, 120b, 120c, . . . and 120x. The wireless communication system may optionally further include a control side electronic device 110. Although the drawing shows the control side electronic device 110 as a base station (e.g., gNB), the control side electronic device 110 may be a roadside unit or even a vehicle itself in the vehicle group. The leading vehicle 130 may correspond to the transmitting device 400 shown in FIG. 4, and any of the following vehicles 120a, 120b, 120c, . . . and 120x may correspond to the terminal side electronic device 200 shown in FIG. 2. In one embodiment, each of the lead vehicle 130 and the following vehicles 120a, 120b, 120c, ..., and 120x can perform autonomous driving (semi-autonomous driving or fully autonomous driving) and communicate with each other via a direct link to form a vehicle group. The lead vehicle 130 may use a highly directional beam to transmit perception data acquired by the lead vehicle 130 (e.g., data acquired by a camera or radar mounted on the lead vehicle 130) and / or a driving strategy to the following vehicles 120a, 120b, 120c, ..., and 120x via a directional antenna in a multicast manner.
[0156] 6A is a schematic diagram of a scenario in which the communication quality between the terminal side electronic device and the transmitting device in the wireless communication system 600A according to an embodiment of the present disclosure deteriorates via a directional antenna. As shown in FIG. 6A, when the length of the vehicle group is too long (e.g., when a new vehicle joins the vehicle group, or the distance between the following vehicle and the leading vehicle increases due to traffic factors), even if there is no obstacle (e.g., a building, a mountain, or the like that blocks the beam) between the leading vehicle 130 and the following vehicle, the following vehicle may fall out of the coverage range of the highly directional beam of the leading vehicle, and the communication quality between the last one or more following vehicles (e.g., the following vehicle 120x) in the vehicle group and the leading vehicle 130 via the directional antenna may deteriorate.
[0157] FIG. 6B shows a schematic diagram of another scenario in which the communication quality via the directional antenna between the terminal side electronic device and the transmitting device in the wireless communication system 600B according to the embodiment of the present disclosure deteriorates. As shown in FIG. 6B, during driving, the arrangement method of the vehicle platoon changes, for example, by turning at an intersection, the following vehicles 120a, 120b may still be within the range of the high directional beam of the directional antenna of the leading vehicle 130, but the following vehicles 120c, 120d may fall out of the high directional beam of the directional antenna of the leading vehicle 130, resulting in deterioration of the communication quality. It should be noted that the vehicle platoon may further change under the influence of other factors, resulting in the following vehicles falling out of the coverage range of the directional beam of the leading vehicle. For example, the following vehicles may also fall out of the beam of the directional antenna of the leading vehicle 130 for other reasons such as temporary detours, traffic jams, etc.
[0158] FIG. 6C is a schematic diagram of another scenario in which the communication quality between the terminal side electronic device and the transmitting device in the wireless communication system 600C according to the embodiment of the present disclosure deteriorates via a directional antenna. As shown in FIG. 6C, the relative positions of the leading vehicle 130 and the following vehicles 120a, 120b, 120c, and 120d are similar to those in FIG. 6B, but since there is an obstacle 610 between the leading vehicle 130 and the following vehicles 120c and 120d, in the third scenario, it may be difficult to ensure the communication quality of the following vehicles 120c and 120d no matter how the beam emitted by the leading vehicle 130 is adjusted. Although FIG. 6C shows the vehicle group turning, this is merely exemplary, and such a scenario may further include other scenarios in which the communication quality between the leading vehicle and the following vehicles via both the directional antenna and the omnidirectional antenna is not ideal due to the presence of an obstacle. For example, when a group of vehicles is traveling straight ahead, an obstacle (such as a large vehicle) may appear between the leading vehicle 130 and the following vehicles, resulting in a deterioration in communication quality.
[0159] 7 is a schematic diagram of a basic flow of an exemplary implementation according to an embodiment of the present disclosure. In S701, first information indicating the status of data communication between the terminal device and the transmitting device via a directional antenna is obtained. The meaning and acquisition manner of the first information can be realized as described above, and will not be described in further detail here.
[0160] In S702, it is determined whether the first information is equal to or less than the first threshold. For example, if the first information is raw data or its quantized value indicating the communication status, the first threshold may be a corresponding data or numerical threshold. If the first information is a binary value indicating the superiority or inferiority of the communication status, the first threshold may be any number between 0 and 1. It should be noted that the above is merely exemplary. The first threshold may further be appropriately set according to the communication request, the type of the first information, etc.
[0161] If the first information is equal to or less than the first threshold, it indicates that the communication quality between the terminal device and the transmitting device via the directional antenna is degraded, and proceed to step S703; otherwise, return to step S701 and continue obtaining the first information later.
[0162] In S703, the second information indicating the communication between the terminal side device and the transmitting device via the omnidirectional antenna is obtained. The meaning and the acquisition manner of the second information can be realized as described above, and will not be described in further detail here.
[0163] In S704, the second information is compared with a certain threshold to determine the influencing factors / events that cause the deterioration of the communication quality. Similar to the first threshold, the certain threshold may be set according to the communication request, the type of the second information, etc.
[0164] JPEG0007658362000001.jpg56170
[0165] In step S705, the communication arrangement between the sending device and the terminal side electronic device is set / adjusted according to the determined influencing factor. The meaning and setting / adjustment manner of the communication arrangement can be realized as described above, and will not be described in detail here. For example, in step S705, the communication arrangement is similarly adjusted for the event determined as above, and the adjusted communication arrangement may be notified to the sending device, and may even be notified to the terminal side electronic device.
[0166] In step S706, the communication between the transmitting device and the terminal side electronic device may be performed based on the adjusted communication configuration. The communication may be performed by various manners known in the art, in particular, via a directional antenna, which will not be described in further detail here.
[0167] It should be noted that each of the above steps may be performed by one or more of the control electronic device, the transmission device, and / or the terminal electronic device. For example, all of the above steps may be performed by any one of the control electronic device, the transmission device, and / or the terminal electronic device. Or, each of the above steps may be performed by different devices among the control electronic device, the transmission device, and / or the terminal electronic device.
[0168] In particular, in the embodiment of the present disclosure, the determination of the communication situation and the communication arrangement setting via the omnidirectional antenna may be performed by various different devices. Hereinafter, an exemplary implementation according to the embodiment of the present disclosure will be described with reference to the drawings.
[0169] 8A to 8C show schematic signaling diagrams for communication between a terminal side electronic device and a transmitting device via an omnidirectional antenna in a wireless communication system according to an embodiment of the present disclosure. It should be noted that, as described above, communication via an omnidirectional antenna is performed based on a communication situation via a directional antenna. Here, for the sake of simplicity, measurement and determination of the communication situation via a directional antenna are omitted.
[0170] FIG. 8A shows a signaling diagram of a schematic method 800A for performing communication between a terminal side electronic device and a transmitting device in a wireless communication system according to an embodiment of the present disclosure. The transmitting device 810 may communicate with the terminating side electronic device 820 via a direct link, or may communicate with the controlling side electronic device 830 via a wireless link such as 5G. The controlling side electronic device 830 may instruct to perform communication and communication configuration setting via the omnidirectional antenna. Before starting the signaling operation of FIG. 8A, the terminal side electronic device 820 may already directly transmit first information (e.g., bit error rate, RSRP, etc.) indicating the communication status via the directional antenna between the terminal side electronic device 820 and the transmitting device 810, or a comparison result between the first information and a first threshold value to the controlling side electronic device 830, or may transmit the first information to the controlling side electronic device 830 via the transmitting device 810.
[0171] In step 801, the control electronic device 830 may send a command to the transmitting device 810 to determine the omni-directional antenna channel quality, for example in response to the first information being below a first threshold or a comparison result between the first information and the first threshold being a specific value.
[0172] In step 802, the transmitting device 810 may transmit a reference signal to the terminal side electronic device 820 via an omni-directional antenna in response to a command.
[0173] In step 803, the terminal side electronic device 820 may directly transmit the second information (e.g., channel quality information or its quantized value, etc.) received from the transmitting device 810 via the omnidirectional antenna in step 802 and determined based on the reference signal to the controlling electronic device 830, and this second information may indicate the communication status via the omnidirectional antenna between the terminal side electronic device 820 and the transmitting device 810. Alternatively, this second information may be further transmitted by the terminal side electronic device 820 to the transmitting device 810 and then transmitted by the transmitting device 810 to the controlling electronic device 830.
[0174] In step 804, the control electronic device 830 may set / adjust a communication arrangement between the terminal electronic device 820 and the transmitting device 810 based on at least the second information received in step 803, and transmit the set / adjusted communication arrangement to the transmitting device 810.
[0175] According to an embodiment, depending on the type and specific information of the communication configuration, the communication configuration may additionally be further transmitted to the terminal side electronic device 820, so that the terminal side electronic device 820 performs data reception accordingly. It should be noted that, in response to a certain communication configuration (e.g., only increasing the transmission power via the directional antenna of the transmitting device), the transmitting device 810 may not transmit the communication configuration to the terminal side electronic device 820, but may directly use the set / adjusted communication configuration to perform data communication. The determination of the communication situation and the setting / adjustment of the communication configuration may be performed as described above, and will not be described in further detail here.
[0176] 8B shows a signaling diagram of a schematic method 800B for performing communication via an omnidirectional antenna between a terminal electronic device and a transmitting device in a wireless communication system according to an embodiment of the present disclosure. The controlling electronic device 830 can instruct to perform communication via an omnidirectional antenna, and the transmitting device 810 can perform communication configuration. Before starting the signaling operation of FIG. 8B, the first information or the comparison result between the first information and a first threshold has already been sent to the controlling electronic device 830, similar to FIG. 8A.
[0177] In step 811, the control electronic device 830 may send a command to the transmitting device 810 to determine the omni-directional antenna channel quality, for example in response to the first information being below a first threshold or a comparison result between the first information and the first threshold being a certain value.
[0178] In step 812, the transmitting device 810 may transmit a reference signal to the terminal side electronic device 820 via an omni-directional antenna.
[0179] In step 813, the terminal side electronic device 820 may transmit to the transmitting device 810 second information (e.g., channel quality information or its quantized value, etc.) determined based on the reference signal received from the transmitting device 810 via the omnidirectional antenna in step 812, and the second information may indicate the communication status via the omnidirectional antenna between the terminal side electronic device 820 and the transmitting device 810. The terminal side electronic device 820 may further transmit the second information to the transmitting device 810 by relaying through the control side electronic device 830.
[0180] In step 814, the sending device 810 may set / adjust a communication configuration between the terminal side electronic device 820 and the sending device 810 based on at least the second information received in step 813. Additionally, depending on the type and specific information of the communication configuration, the communication configuration may be transmitted to the terminal side electronic device 820 in a manner similar to FIG. 8A.
[0181] 8A and 8B, the control electronic device 830 is used to obtain communication quality information between the terminal electronic device 820 and the transmitting device 810 via an omnidirectional antenna, and / or to determine whether it is necessary to set up a communication arrangement between the terminal electronic device 820 and the transmitting device 810. The control electronic device 830 can make a decision by synthesizing the received information. Also, even if there is a communication link interruption between the terminal electronic device 820 and the transmitting device 810, the control electronic device 830 can communicate with both the terminal electronic device 820 and the transmitting device 810.
[0182] FIG. 8C illustrates a signaling diagram of a schematic method 800C for performing communication via an omnidirectional antenna between a terminal side electronic device and a transmitting device in a wireless communication system according to an embodiment of the present disclosure. The transmitting device 810 can instruct to perform communication via an omnidirectional antenna and communication configuration setting. In FIG. 8C, the controlling electronic device 830 is not illustrated because the controlling electronic device 830 may not participate in the communication via an omnidirectional antenna between the terminal side electronic device 820 and the transmitting device 810. Before starting the signaling operation of FIG. 8C, the first information or the comparison result between the first information and the first threshold value has already been transmitted to the transmitting device 810.
[0183] In step 821, the transmitting device 810 may transmit a reference signal to the terminal side electronic device 820 via the omnidirectional antenna, for example, in response to the first information being below a first threshold or a comparison result between the first information and the first threshold being a particular value.
[0184] In step 822, the terminal side electronic device 820 may transmit to the transmitting device 810 second information (e.g., channel quality information or a quantized value thereof) determined based on the reference signal received from the transmitting device 810 via the omnidirectional antenna in step 821, and this second information may indicate the communication status between the terminal side electronic device 820 and the transmitting device 810 via the omnidirectional antenna.
[0185] In step 823, the sending device 810 may set / adjust a communication configuration between the terminal side electronic device 820 and the sending device 810 based on at least the second information received in step 822. Additionally, according to the type and specific information of the communication configuration, the communication configuration may be transmitted to the terminal side electronic device 820 in a manner similar to FIG. 8A.
[0186] 8A to 8C, the transmission device 810 or the control side electronic device 830 sets the communication arrangement between the terminal side electronic device 820 and the transmission device 810. It should be understood that the implementation of the present disclosure is not limited thereto, and as an example, the setting may be further determined by the terminal side electronic device 820 and transmitted to the transmission device 810 and / or the control side electronic device 830. For example, the terminal side electronic device 820 may determine the setting of the communication arrangement after sharing data with an adjacent terminal side electronic device, a base station, a roadside unit, or the like.
[0187] Below, a schematic signaling diagram of communication arrangement setting between the terminal side electronic device and the transmitting device according to an embodiment of the present disclosure will be described with reference to Figures 9A to 9C. According to the embodiment of the present disclosure, the communication arrangement between the terminal side electronic device and the transmitting device is appropriately adjusted / set according to the determined scenario of communication between the terminal side electronic device and the transmitting device.
[0188] According to an embodiment of the present invention, for a scenario such as that shown in FIG. 6A, communication quality deteriorates due to the distance between the following vehicle and the leading vehicle being too far, but the following vehicle 120x is still in the direction of the beam of the directional antenna of the leading vehicle 130 and there are no obstacles between the two, so the communication quality can be improved by increasing the transmission power via the directional antenna of the leading vehicle 130 or using relaying.
[0189] In one embodiment, in response to second information indicating a communication status via an omnidirectional antenna between the terminal side electronic device and the transmitting device falling below a second threshold ∈0, i.e., a first type of scenario occurring, at least one of relaying communication between the transmitting device and the terminal side electronic device via a directional antenna using a relay device and increasing the transmission power via the directional antenna of the transmitting device, wherein the relay device may be a base station, a roadside unit, or another terminal side electronic device, etc.
[0190] In one embodiment, in response to this second information falling below a second threshold ∈0, the transmission power via the directional antenna of the transmitting device is increased, and if the first information indicating the communication status via the directional antenna between the terminal side electronic device and the transmitting device, obtained when the transmission power is increased to a specific power, is still below the first threshold, the relay device relays the communication via the directional antenna between the transmitting device and the terminal side electronic device.
[0191] FIG. 9A shows an exemplary signaling diagram of a schematic method 900A of setting up a communication configuration for a type of scenario (the scenario shown in FIG. 6A) in which communication quality between a terminal side electronic device and a transmitting device in a wireless communication system according to an embodiment of the present disclosure deteriorates.
[0192] As shown in FIG. 9A, in step 901, in response to second information indicating a communication status via an omnidirectional antenna between the terminal side electronic device 920 and the transmitting device 910 received (e.g., from the terminal side electronic device 920 or the control side electronic device, etc.) falling below a second threshold ∈0, the transmitting device 910 may increase the transmitting power via the directional antenna.
[0193] In step 902, the transmitting device 910 transmits a reference signal to the terminal side electronic device 920 via a directional antenna at increased power.
[0194] In step 903, the transmitting equipment 910 receives first information (indicating the communication status via the directional antenna between the terminal side electronic device 920 and the transmitting equipment 910) determined by the terminal side electronic device 920 based on the reference signal transmitted from the transmitting equipment 910 in step 902.
[0195] In step 904, the transmitting device 910 judges whether the first information falls below a first threshold, i.e., judges the communication quality status via the directional antenna between the transmitting device 910 and the terminal side electronic device 920 after increasing the transmission power of the directional antenna.
[0196] In response to the first information being determined to be equal to or greater than the first threshold, in a subsequent operation, the transmitting device may use this transmission power to perform directional data communication. As an example, the transmitting device may directly use the increased transmission power to communicate with the terminal side electronic device via the directional antenna without notifying the terminal side electronic device of the communication configuration (e.g., the increased transmission power). As another example, the transmitting device may notify the terminal side electronic device of the relevant transmission configuration. Thereby, the terminal side electronic device may receive the information more appropriately, such as by adjusting the reception power. This allows the impact of the event on the communication quality to be effectively suppressed by a simple power adjustment.
[0197] In response to the first information being determined to be below the first threshold, communication may be performed using a relay. In step 905, the transmitting device 910 may transmit a command to the relay device 930 to function as a relay for the terminal side electronic device 920. The relay device 930 may be a base station, a roadside unit, an adjacent terminal side electronic device, or any other suitable electronic device. The transmitting device 910 may select the relay device 930 based on information such as the positions of the transmitting device 910, the terminal side electronic device 920, the base station, the roadside unit, and other electronic devices, the direction and speed of the transmitting device 910 and the terminal side electronic device 920, and the communication quality of other terminal side electronic devices.
[0198] In step 906, the sending device 910 may send a communication configuration, such as information of the relay device 930, to the terminal side electronic device 920. It should be understood that the order of steps 905 and 906 may be interchanged.
[0199] In step 907, the transmitting device 910 may transmit the communication data to the relay device 930. Then, in step 909, the relay device 930 may transmit the communication data to the terminal side electronic device 920.
[0200] It should be noted that, according to an embodiment of the present disclosure, the transmission power through the directional antenna of the transmitting device may be continuously increased or increased in a certain step to a certain transmission power (e.g., a rated maximum transmission power of the directional antenna), and the first information may be obtained and determined each time the transmission power is increased. In one embodiment, the above steps 901-904 may be repeated until the first information obtained at a certain transmission power exceeds a first threshold. In a subsequent operation, this transmission power is used to perform directional data communication. If the first information obtained when the transmission power is increased to this specific transmission power is still below the first threshold, steps 905-908 are performed again.
[0201] As another example, step 901 may be performed only once, increasing the transmission power of the transmitting device by a specific value or directly increasing the transmission power to a specific transmission power, and then communicating directly using the relay if it is determined in step 904 that the first information is below the first threshold.
[0202] According to an embodiment of the present disclosure, instead of increasing the power of the transmitting device, the communication may be performed directly using a relay. For example, when the second information falls below a second threshold ∈ 0, steps 905 to 907 may be performed directly. By performing the communication using a relay, reliable communication can be ensured, but delays may be larger than when the transmission power of the antenna of the transmitting device is increased.
[0203] This makes it possible to suppress the degradation of communication quality due to scenario 1 through appropriate adjustments.
[0204] According to an embodiment of the present invention, for the second type of scenario shown in FIG. 6B, the following vehicle is out of the beam coverage range of the leading vehicle, but there is no obstacle between the leading vehicle 130 and the following vehicles 120c, 120d that significantly blocks the communication link (i.e., the communication quality between the leading vehicle 130 and the following vehicles 120c, 120d via the omnidirectional antenna can meet the requirements), so the communication quality between the leading vehicle 130 and the following vehicles 120c, 120d can be improved by adjusting the beam transmitted from the leading vehicle 130 via the directional antenna. Of course, it should be noted that relaying can also be used to overcome this scenario and improve the communication quality between the leading vehicle 130 and the following vehicles 120c, 120d via the directional antenna. However, relaying may increase delays, especially when the amount of data multicast by the leading vehicle 130 is relatively large. The following will further describe, in conjunction with FIG. 9B, the manner of setting a communication arrangement between the leading vehicle 130 and the following vehicle 120d (or the following vehicle 120c) in the second type of scenario.
[0205] FIG. 9B shows a signaling diagram of a schematic method 900B of setting up a communication configuration for a second type of scenario in which the communication quality between the terminal side electronic device and the transmitting device in the wireless communication system according to the embodiment of the present disclosure is degraded. As described above, in the second type of scenario, the terminal side electronic device 920 is out of the beam of the directional antenna of the transmitting device 910, but since there is no obstacle between them that significantly blocks the communication link, the communication quality can be improved by adjusting the beam of the directional antenna of the transmitting device 910. For example, the beam coverage range may be widened, the beam angle may be changed, multiple beams may be adopted, etc. Also, it may be changed to use an omnidirectional antenna (if the directional antenna and the omnidirectional antenna are the same set of antenna array, the antenna array may be arranged to perform omnidirectional transmission).
[0206] JPEG0007658362000002.jpg52170
[0207] In step 912, the transmitting device 910 may use a beam-adjusted directional antenna (or an omni-directional antenna) to transmit a communication configuration (eg, beam direction, etc.) and a reference signal to the terminal side electronic device 920.
[0208] In step 913, the transmitting device 910 receives information (e.g., channel quality information) indicating a communication state via the adjusted directional antenna (or omnidirectional antenna) between the terminal side electronic device 920 and the transmitting device 910, which is determined by the terminal side electronic device 920 based on the reference signal transmitted by the transmitting device 910 in step 912, and judges whether the communication state after the adjustment has improved. If the channel quality information received in step 913 satisfies the communication requirement, the transmitting device 910 may transmit communication data to the terminal side electronic device 920 using the adjusted directional antenna, as in step 914.
[0209] Preferably, the transmitting device 910 may notify the terminal side electronic device of the arrangement information of the adjusted directional antenna before performing data communication. This allows the terminal side electronic device to more appropriately receive data from the transmitting device 910. In this case, the arrangement information of the adjusted directional antenna may be transmitted as communication arrangement information. According to another example, the arrangement information of the adjusted directional antenna may not be notified to the terminal side electronic device, and the transmitting device may transmit using the arrangement of the adjusted directional antenna. The terminal side electronic device determines its own optimal reception arrangement using a reception method known in the art, thereby performing appropriate reception.
[0210] The above describes the basic flow of adjusting the beam once. It should be noted that, according to an embodiment of the present disclosure, the beam may be adjusted multiple times. According to an embodiment, if the channel quality information received in step 913 does not satisfy the communication requirement, the transmitting device 910 may repeat steps 911-913 to further adjust the antenna beam. For example, the beam coverage range, angle, and number of beams may be further adjusted. For example, the beam adjustment may be performed continuously or stepwise, similar to the cyclic process described above with reference to FIG. 9A, and each time the adjustment is performed, it may be verified whether the communication situation after the adjustment is improved.
[0211] If the communication situation still cannot be improved even after performing a certain beam adjustment (e.g., the beam is adjusted to a certain coverage range, angle, number of beams, or even omnidirectional beam), the communication may be performed using relay, and the relay information may be notified to the terminal side electronic device, as shown in steps 905 to 908 described with reference to Fig. 9A, and will not be described in further detail here.
[0212] In the third type of scenario shown in Fig. 9C, according to the embodiment of the present invention, the control side electronic device 110 or other following vehicles in the vehicle group (e.g., following vehicle 120b in Fig. 6C) can function as a relay to improve the communication quality between the leading vehicle 130 and the following vehicle 120d (or 120c). In the following, the manner of setting the communication arrangement between the leading vehicle 130 and the following vehicle 120d (or following vehicle 120c) in the third type of scenario will be further described in conjunction with Fig. 9C.

[0214] JPEG0007658362000004.jpg62170
[0215] In one embodiment, in response to a difference in first information (information indicating the communication status via a directional antenna between the terminal side electronic device and the transmitting device) between the terminal side electronic device 920 and an adjacent terminal side electronic device exceeding a specific threshold value (i.e., the communication quality via the directional antenna between the adjacent terminal side electronic device and the transmitting device 910 meets the requirement), the adjacent terminal side electronic device relays communication between the transmitting device 910 and the terminal side electronic device 920.
[0216] In step 922, the sending device 910 may send a communication configuration, such as information of the relay device 930, to the terminal side electronic device 920. It should be understood that the order of steps 921 and 922 may be interchanged.
[0217] In step 923, the transmitting device 910 may transmit the communication data to the relay device 930. Then, in step 924, the relay device 930 may transmit the communication data to the terminal side electronic device 920.
[0218] According to the embodiment of the present disclosure, the relayed data communication status may be verified, and if the data communication status is still not good, another suitable relay device may be further selected.
[0219] The above is an exemplary description of the process of adjusting communication arrangement for different scenarios / events according to the embodiments of the present disclosure. It should be noted that the above is merely exemplary, and communication arrangement adjustment may be performed in a similar manner for other types of scenarios.
[0220] According to an embodiment of the present disclosure, by accurately judging the communication situation and appropriately adjusting the communication arrangement based on the judgment result, it is possible to appropriately suppress the adverse impact of adverse factors / events on the communication in the wireless communication system, and improve the communication in the wireless communication system to make it more robust.
[0221] In some of the above embodiments, the terminal side electronic device estimates the downlink channel quality using the reference signal received from the transmitting device. Since the wireless channels are compatible, the terminating side electronic device may transmit a reference signal to the transmitting device, and the transmitting device may estimate the uplink channel quality, and set the communication arrangement between the transmitting device and the terminating side electronic device accordingly. In particular, compared with the above embodiments, in this embodiment utilizing the channel compatibility, the operations related to the judgment of the communication status between the terminal side electronic device and the transmitting device are mutually exchanged. Among them, the terminal side electronic device may be regarded as operating in a manner similar to the above-mentioned transmitting device, and the transmitting device may be regarded as operating in a manner similar to the above-mentioned terminal side electronic device.
[0222] Hereinafter, an electronic device and a communication method in a wireless communication system that performs multicast using a direct link based on channel compatibility according to an embodiment of the present disclosure will be described with reference to the accompanying drawings.
[0223] 10 shows a schematic block diagram of a terminal side electronic device 1000 according to an embodiment of the present disclosure. The terminal side electronic device 1000 may correspond to the terminal side electronic device 120a, 120b or 120c in FIG. 1. For clarity, the following will be described by taking the case where the first type of antenna is a directional antenna and the second type of antenna is an omnidirectional antenna as an example. As shown in FIG. 10, the terminal side electronic device 1000 may include a directional antenna 1010, an omnidirectional antenna 1020 and a processing circuit 1030.
[0224] The processing circuit 1030 can provide various functions of the terminal side electronic device 1000. According to an embodiment of the present disclosure, the processing circuit 1030 may be arranged to receive first channel quality information between the terminal side electronic device 1000 and the transmitting device via a directional antenna, estimated based on a first reference signal transmitted from the terminal side electronic device 1000 via a directional antenna by the transmitting device, perform communication between the terminal side electronic device 1000 and the transmitting device via an omnidirectional antenna based on the first channel quality information, and receive second channel quality information between the terminal side electronic device 1000 and the transmitting device via an omnidirectional antenna, estimated based on a second reference signal transmitted from the terminal side electronic device 1000 via the omnidirectional antenna by the transmitting device, and the communication arrangement between the terminal side electronic device 1000 and the transmitting device can be set based on at least the second channel quality information.
[0225] According to an embodiment of the present disclosure, the processing circuit 1030 may include each unit for realizing the above-mentioned functions, for example, a directional antenna channel quality information receiving unit 1032, an omnidirectional antenna communication initiating unit 1034, and an omnidirectional antenna channel quality information receiving unit 1036, and the processing circuit 1030 may optionally include a communication arrangement setting unit 1038. The communication arrangement setting unit 1038 may be located outside the terminal side electronic device 1000, and is drawn with a dotted line. These units included in the processing circuit 1030 may be communicatively coupled to each other (not shown), and / or may be coupled to one or more of the directional antenna 1010 and the omnidirectional antenna 1020 (not shown). It should be noted that although each unit is shown as a separate unit in FIG. 10, one or more of these units may be integrated into one unit or divided into multiple units. Also, although FIG. 10 illustrates four units of the processing circuit 1030, the processing circuit 1030 may further include other possible units.
[0226] According to an embodiment of the present disclosure, the directional antenna channel quality information receiving unit 1032 may be arranged to receive first channel quality information via a directional antenna between the terminal side electronic device 1000 and the transmitting device, which is estimated based on a first reference signal transmitted by the transmitting device from the terminal side electronic device 1000 via the directional antenna 1010. For example, after a radio signal including the first channel quality information is received from the transmitting device or the control side electronic device by the directional antenna 1010, the first channel quality information is obtained by processing such as down-conversion, analog-to-digital conversion, etc. Then, the first channel quality information may be transmitted to the directional antenna channel quality information receiving unit 1032.
[0227] As described above, this first channel quality information may include any one of the power parameters (e.g., reference signal received power (RSRP) and reference signal received quality (RSRQ)) of the first reference signal received from the terminal side electronic device 1000 via the directional antenna 1010, and the channel state (e.g., channel quality indicator (CQI)) via the directional antenna between the terminal side electronic device 1000 and the transmitting device estimated based on the received first reference signal.
[0228] According to an embodiment, the first reference signal may be transmitted by the terminal side electronic device 1000 spontaneously or in response to a request / command, as described with respect to the first reference signal transmitted by the transmitting device. For example, the first reference signal may be transmitted continuously or periodically, or in response to a deterioration in the quality of data communication via the directional antenna acquired by the transmitting device, or in response to a request / command of the transmitting device and / or the controlling side electronic device. The specific operation manner may be as described above, and will not be described in further detail here.
[0229] According to an embodiment of the present disclosure, the omnidirectional antenna communication initiation unit 1034 may be arranged to perform communication between the terminal side electronic device 1000 and the transmitting device via the omnidirectional antenna based on the first channel quality information. The omnidirectional antenna communication initiation unit 1034 may further perform communication between the terminal side electronic device 1000 and the transmitting device via the omnidirectional antenna based on a command transmitted from the transmitting device or the control side electronic device based on the first channel quality information.
[0230] In one embodiment, the terminal side electronic device 1000 may receive the first channel quality information or the comparison result of the first channel quality information and the first threshold from the transmitting device or the controlling electronic device. In response to the first channel quality information being below the first threshold or the comparison result of the first channel quality information and the first threshold being a specific value, the terminal side electronic device 1000 performs communication between the terminal side electronic device 1000 and the transmitting device via the omnidirectional antenna, either spontaneously or based on a command from the controlling electronic device. In one embodiment, the terminal side electronic device 1000 further performs communication between the terminal side electronic device 1000 and the transmitting device via the omnidirectional antenna, either spontaneously or based on a command from the controlling electronic device, in response to a change between the current first channel quality information and the previously received first channel quality information being within a predetermined range.
[0231] For example, the terminal side electronic device 1000 may transmit a second reference signal to the transmitting device via the omnidirectional antenna 1020 to perform communication via the omnidirectional antenna. The second reference signal may be transmitted by the terminal side electronic device 1000 spontaneously or in response to a request / command, as described with respect to the second reference signal transmitted by the transmitting device. For example, the second reference signal may be transmitted continuously or periodically, or in response to the first channel quality information falling below the first threshold, or in response to a request / command issued by the transmitting device and / or the control side electronic device based on the first channel quality information falling below the first threshold. The specific operation manner may be as described above, and will not be described in further detail here.
[0232] According to an embodiment of the present disclosure, the omnidirectional antenna channel quality information receiving unit 1036 may be arranged to receive second channel quality information between the terminal side electronic device 1000 and the transmitting device via the omnidirectional antenna, which is estimated based on a second reference signal transmitted by the transmitting device from the terminal side electronic device 1000 via the omnidirectional antenna. For example, after a radio signal including the second channel quality information is received from the transmitting device or the control side electronic device by the omnidirectional antenna 1020, the second channel quality information is obtained by processing such as down-conversion, analog-to-digital conversion, etc. Then, the second channel quality information may be transmitted to the omnidirectional antenna channel quality information receiving unit 1036. The transmitting device may determine the second channel quality information by any suitable channel quality estimation technique.
[0233] In one embodiment, the second channel quality information may include any one of power parameters (e.g., reference signal received power (RSRP) and reference signal received quality (RSRQ)) of the second reference signal received from the terminal side electronic device 1000 via the omnidirectional antenna 1020, and a channel condition (e.g., channel quality indicator (CQI)) via the omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device estimated based on the received second reference signal.
[0234] According to an embodiment of the present disclosure, a communication arrangement between the terminal side electronic device 1000 and the transmitting device may be set based on at least the second channel quality information. In an embodiment, the processing circuit 1030 may include a communication arrangement setting unit 1038, and the communication arrangement setting unit 1038 may be configured to set a communication arrangement between the terminal side electronic device 1000 and the transmitting device based on at least the second channel quality information. It should be understood that the communication arrangement between the terminal side electronic device 1000 and the transmitting device may be set by the transmitting device or the control side electronic device. The meaning of the communication arrangement and the setting / adjustment operation may be as described above, and will not be described in further detail here.
[0235] The implementation of the directional antenna 1010 and the omnidirectional antenna 1020 may be similar to the above-mentioned directional antenna 210 and the omnidirectional antenna 220, and will not be described in further detail here. It should be understood that Fig. 10 is merely a schematic structural layout of the terminal side electronic device, and the terminal side electronic device 1000 may further include other possible components (e.g., memory, etc.) similar to the above-mentioned terminal side electronic device 200. No further description will be given here.
[0236] FIG. 11 shows a flow chart of a communication method 1100 used in a terminal side electronic device according to an embodiment of the present disclosure, where the terminal side electronic device is, for example, the terminal side electronic device 1000 shown in FIG.
[0237] In step S1110, the terminal side electronic device 1000 may receive, from the transmitting device or the control side electronic device, first channel quality information via a first type antenna between the terminal side electronic device 1000 and the transmitting device, which is estimated based on a first reference signal transmitted by the transmitting device from the terminal side electronic device 1000 via a first type antenna (e.g., directional antenna 1010) of the terminal side electronic device 1000. This step S1110 may be executed, for example, by the directional antenna channel quality information receiving unit 1032 in FIG.
[0238] Then, the process proceeds to step S1120. In step S1120, the terminal side electronic device 1000 may perform communication between the terminal side electronic device 1000 and the transmitting device via a second type antenna based on the first channel quality information. This step S1120 may be executed by, for example, the omnidirectional antenna communication initiation unit 1034 in FIG. 10.
[0239] Then, the process proceeds to step S1130. In step S1130, the terminal side electronic device 1000 may receive, from the transmitting device or the control side electronic device, second channel quality information between the terminal side electronic device 1000 and the transmitting device via the second type antenna, which is estimated based on a second reference signal transmitted from the terminal side electronic device 1000 via the second type antenna (e.g., the omnidirectional antenna 1020) of the terminal side electronic device 1000 by the transmitting device. This step S1130 may be executed, for example, by the omnidirectional antenna channel quality information receiving unit 1036 in FIG. 10.
[0240] Then, the process proceeds to step S1140. In step S1140, the terminal side electronic device 1000 may set a communication arrangement between the terminal side electronic device 1000 and the transmitting device based on at least the second channel quality information. This step S1140 may be performed, for example, by the communication arrangement setting unit 1038 in FIG. 10. Step S1140 is depicted with a dotted line. The reason is that in some embodiments, step S1140 may also be performed by a device other than the terminal side electronic device 1000 (for example, a transmitting device or a controlling side electronic device). For example, in order for the controlling side electronic device to set the communication arrangement between the terminal side electronic device 1000 and the transmitting device, the transmitting device may transmit to the controlling side electronic device any one of the second channel quality information and a comparison result between the second channel quality information and a specific threshold value. For example, the communication arrangement setting unit of the transmitting device may set the communication arrangement between the terminal side electronic device 1000 and the transmitting device based on the second channel quality information.
[0241] FIG. 12 shows a schematic block diagram of a transmitting device 1200 according to an embodiment of the present disclosure. The transmitting device 1200 may correspond to the transmitting device 130 in FIG. 1. For clarity, the following will be described by taking the case where the first type of antenna is a directional antenna and the second type of antenna is an omnidirectional antenna as an example. As shown in FIG. 10, the transmitting device 1200 may include a directional antenna 1210, an omnidirectional antenna 1220 and a processing circuit 1230. For convenience, the following will describe the function of the processing circuit 1230 of the transmitting device 1200 in FIG. 10 while combining the terminal side electronic device 1000 according to the embodiment of the present disclosure shown in FIG. 10.
[0242] The processing circuit 1230 can provide various functions of the transmitting device 1200. According to an embodiment of the present disclosure, the processing circuit 1230 may be arranged to obtain first channel quality information via a directional antenna between the terminal side electronic device 1000 and the transmitting device 1200, estimated based on a first reference signal transmitted from the terminal side electronic device 1000 via a directional antenna 1010, and obtain second channel quality information via an omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device 1200, estimated based on a second reference signal transmitted from the terminal side electronic device 1000 via an omnidirectional antenna 1020, where communication via the omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device 1200 is performed based on the first channel quality information, and a communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200 can be set based on at least the second channel quality information.
[0243] According to an embodiment of the present disclosure, the processing circuit 1230 may include each unit for implementing the above-mentioned functions, for example, a directional antenna channel quality information acquisition unit 1232, an omnidirectional antenna channel quality information acquisition unit 1234, and the processing circuit 1230 may optionally include a communication arrangement setting unit 1236. The communication arrangement setting unit 1236 may be located outside the transmitting device 1200, and is drawn with a dotted line. These units included in the processing circuit 1230 may be communicatively coupled to each other (not shown), and / or may be coupled to one or more of the directional antenna 1210 and the omnidirectional antenna 1220 (not shown). It should be noted that although each unit is shown as a separate unit in FIG. 12, one or more of these units may be integrated into one unit or divided into multiple units. Also, although three units of the processing circuit 1230 are shown in FIG. 12, the processing circuit 1230 may further include other possible units.
[0244] According to an embodiment of the present disclosure, the directional antenna channel quality information acquisition unit 1232 may be configured to acquire first channel quality information via a directional antenna between the terminal side electronic device 1000 and the transmitting device 1200, the first channel quality information being estimated based on a first reference signal transmitted from the terminal side electronic device 1000 via the directional antenna 1010.
[0245] The first channel quality information may include any one of power parameters (e.g., Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ)) of the first reference signal received from the terminal side electronic device 1000 via the directional antenna 1010, and a channel condition (e.g., Channel Quality Indicator (CQI)) via the directional antenna between the terminal side electronic device 1000 and the transmitting device 1200 estimated based on the received first reference signal. In one embodiment, the first channel quality information may be generated by the transmitting device 1200 and transmitted to the terminal side electronic device 1000 and / or the controlling side electronic device.
[0246] According to an embodiment of the present disclosure, the omnidirectional antenna communication status acquisition unit 1234 may be arranged to acquire second channel quality information via the omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device 1200, which is estimated based on the second reference signal transmitted from the terminal side electronic device 1000 via the omnidirectional antenna 1020. This second channel quality information may include channel quality information via the omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device 1200, or a quantized value thereof, which is determined based on the second reference signal transmitted from the terminal side electronic device 1000 via the omnidirectional antenna. In one embodiment, this second channel quality information may be generated by the transmitting device 1200 and transmitted to the terminal side electronic device 1000 and / or the control side electronic device. In one embodiment, the communication via the omnidirectional antenna between the terminal side electronic device 1000 and the transmitting device 1200 is performed based on the first channel quality information via the directional antenna between the terminal side electronic device 1000 and the transmitting device 1200, which is acquired by the directional antenna channel quality information acquisition unit 1232. For example, in response to the first channel quality information indicating that the communication conditions via a directional antenna between the terminal side electronic device 1000 and the transmitting device 1200 are relatively poor (e.g., the first channel quality information is below a certain threshold), communication between the terminal side electronic device 1000 and the transmitting device 1200 may be performed via an omnidirectional antenna.
[0247] According to an embodiment of the present disclosure, a communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200 may be set based on at least the second channel quality information. In an embodiment, the processing circuit 1230 may include a communication arrangement setting unit 1236, and the communication arrangement setting unit 1236 may be configured to set a communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200 based on at least the second channel quality information. It should be understood that the communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200 may be set by the terminal side electronic device 1000 or the control side electronic device. A specific method of setting the communication arrangement will be described later.
[0248] The implementation of the directional antenna 1210 and the omnidirectional antenna 1220 may be similar to the directional antenna 410 and the omnidirectional antenna 420 described above, and will not be described in further detail here. It should be understood that Fig. 12 is only a schematic structural layout of the transmitting device. The transmitting device 1200 may further include other possible components (e.g., memory, etc.) similar to the transmitting device 400 described above, and will not be described in further detail here.
[0249] 13 shows a flowchart of a communication method 1300 used in a sending device according to an embodiment of the present disclosure. The following describes the communication method 1300 in conjunction with FIG. 10 and FIG. 12. Wherein, the sending device is, for example, the sending device 1200 shown in FIG. 12.
[0250] In step S1310, the transmitting device 1200 acquires first channel quality information via a first type antenna between the terminal side electronic device 1000 and the transmitting device 1200, which is estimated based on a first reference signal transmitted from the terminal side electronic device 1000 via a first type antenna (e.g., directional antenna 1010) of the terminal side electronic device 1000. This step S1310 may be executed by, for example, the directional antenna channel quality information acquisition unit 1232 in Fig. 12. An example of the first channel quality information has already been described, and will not be described further here.
[0251] According to an embodiment, the transmitting device 1200 obtaining the first channel quality information via the first type antenna between the terminal side electronic device 1000 and the transmitting device 1200 includes determining a data communication quality via the first type antenna between the terminal side electronic device 1000 and the transmitting device 1200, and determining the first channel quality information based on a received first reference signal transmitted from the terminal side electronic device 1000 via the first type antenna in response to the data communication quality via the first type antenna between the terminal side electronic device 1000 and the transmitting device 1200 falling below a corresponding threshold. The transmitting device 1200 can determine the first channel quality information by any suitable channel quality estimation technique.
[0252] Then, the process proceeds to step S1320. In step S1320, the transmitting device 1200 acquires second channel quality information via a second type antenna between the terminal side electronic device 1000 and the transmitting device 1200, the second channel quality information being estimated based on a second reference signal transmitted from the terminal side electronic device 1000 via a second type antenna (for example, the omnidirectional antenna 1020). This step S1320 may be executed by, for example, the omnidirectional antenna channel quality information acquisition unit 1234 in FIG. 12.
[0253] Then, the process proceeds to step S1330. In step S1330, the transmitting device 1200 may set a communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200 based on at least the second channel quality information. This step S1330 may be performed, for example, by the communication arrangement setting unit 1236 in FIG. 12. Step S1330 is depicted with a dotted line. The reason is that in some embodiments, step S1330 may also be performed by a device other than the transmitting device 1200 (for example, the terminal side electronic device 1000 or the control side electronic device). For example, in order for the terminal side electronic device 1000 or the control side electronic device to set a communication arrangement between the terminal side electronic device 1000 and the transmitting device 1200, the transmitting device 1200 may transmit any one of the second channel quality information and a comparison result between the second channel quality information and a specific threshold value to the terminal side electronic device 1000 or the control side electronic device.
[0254] The following describes an exemplary implementation of communication status determination and communication allocation setting in a wireless communication system according to an embodiment of the present disclosure with reference to the accompanying drawings. Similar to the above-mentioned embodiment, in the wireless communication system of this embodiment, the communication status of the directional antenna and the communication status of the omnidirectional antenna are first determined to accurately determine the influencing factors / events that affect the deterioration of communication quality, and then the communication allocation is appropriately adjusted / set based on the determination result. This can improve the communication quality in the communication system and improve the robustness of communication.
[0255] It should be noted that in this embodiment, the communication status determination and communication arrangement setting may be performed in a manner similar to the above-mentioned embodiment. For example, the communication status event may be determined as shown in the flow of FIG. 7, for example, the event determination shown in FIG. 6A to FIG. 6C may be performed, for example, communication may be performed via an omnidirectional antenna by various devices as shown in FIG. 8A to FIG. 8C, and for example, corresponding communication arrangement setting / adjustment may be performed for various events as shown in FIG. 9A to FIG. 9C. However, although the operations are performed in a similar manner, the subject of these operations is interchanged compared to the above-mentioned embodiment in consideration of channel compatibility.
[0256] 14A to 14C are schematic signaling diagrams for communication between a terminal side electronic device and a transmitting device via an omnidirectional antenna in a wireless communication system according to an embodiment of the present disclosure. The transmitting device 1410, the terminal side electronic device 1420, and the control side electronic device 1430 shown in Fig. 14A to 14C basically have the same meaning as the transmitting device, the terminal side electronic device, and the control side electronic device described above, so they will not be described in more detail here.
[0257] The signaling operations shown in Figures 14A to 14C may be similar to the signaling operations shown in Figures 8A to 8C. In particular, steps 1401 to 1404 shown in Figure 14A, steps 1411 to 1414 shown in Figure 14B, and steps 1421 to 1423 shown in Figure 14C may be performed in a manner similar to steps 801 to 804 shown in Figure 8A, steps 811 to 814 shown in Figure 8B, and steps 821 to 823 shown in Figure 8C, respectively, except that the executing entities may be different. For this reason, further detailed description will not be given here.
[0258] 15A to 15C respectively show signaling diagrams of a schematic method of setting communication arrangement for a scenario in which communication quality between a terminal side electronic device and a transmitting device in a wireless communication system according to an embodiment of the present disclosure deteriorates. The transmitting device 1510, the terminal side electronic device 1520, and the control side electronic device 1530 shown in Fig. 15A to 15C basically have the same meaning as the transmitting device, the terminal side electronic device, and the control side electronic device described above, so they will not be described in more detail here.
[0259] The signaling operations shown in Figures 15A to 15C may be similar to the signaling operations shown in Figures 9A to 9C. In particular, steps 1501 to 1508 shown in Figure 15A, steps 1511 to 1515 shown in Figure 15B, and steps 1521 to 1524 shown in Figure 15C may be performed in a manner similar to steps 901 to 908 shown in Figure 9A, steps 911 to 915 shown in Figure 9B, and steps 921 to 924 shown in Figure 9C, respectively, except that the executing entities may be different. For this reason, further detailed description will not be given here.
[0260] The above describes an embodiment of the present disclosure that utilizes channel compatibility. According to this embodiment, the communication situation can be accurately judged, and the communication arrangement can be appropriately adjusted based on the judgment result, so that the adverse influence of the adverse factors / events on the communication in the wireless communication system can be appropriately suppressed, and the communication in the wireless communication system can be improved and made more robust.
[0261] [Application example] Although the present disclosure describes an example of a cooperative communication scenario in a platoon, it should be understood that the application scenario of the present disclosure is not limited to the cooperative communication scenario in a platoon. The improvement proposed in the present disclosure can be applied to any cooperative communication application scenario, such as unmanned aerial vehicle formation flying, cooperative operation of intelligent engineering robots, etc.
[0262] It should be noted that the above description is merely exemplary. The embodiments of the present disclosure may be implemented in any other suitable manner, and the advantageous effects of the embodiments of the present disclosure may be achieved in the same manner. The embodiments of the present disclosure may also be applied to other similar applications, and the advantageous effects of the embodiments of the present disclosure may be achieved in the same manner.
[0263] It should be understood that the machine-readable instructions in the machine-readable storage medium or program product according to the embodiments of the present disclosure can be configured to perform operations corresponding to the above-mentioned machine and method embodiments. When referring to the above-mentioned machine and method embodiments, the machine-readable storage medium or program product embodiments are obvious to those skilled in the art and will not be described repeatedly. The machine-readable storage medium or program product carrying or containing the above-mentioned machine-executable instructions is also included in the scope of the present disclosure. Such storage media include, but are not limited to, floppy disks, optical disks, magneto-optical disks, memory cards, memory sticks, etc. It should also be understood that the above series of processes and devices may be realized by software and / or firmware. When realized by software and / or firmware, the programs constituting the software are installed from a storage medium or a network into a computer having a dedicated hardware configuration, such as a general-purpose personal computer 1600 shown in FIG. 16, and the computer can execute various functions and the like when various programs are installed. FIG. 16 is a block diagram showing an exemplary configuration of a personal computer that is an information processing device that can be employed in an embodiment of the present disclosure. In one example, the personal computer may correspond to the above exemplary transmission device or terminal side electronic device according to the present disclosure.
[0264] 16, a central processing unit (CPU) 1601 executes various processes based on a program stored in a read-only memory (ROM) 1602 or a program loaded from a storage 1608 to a random access memory (RAM) 1603. The RAM 1603 also stores data required when the CPU 1601 executes various processes, etc., as necessary.
[0265] The CPU 1601, the ROM 1602 and the RAM 1603 are connected to one another via a bus 1604. An input / output interface 1605 is also connected to the bus 1604.
[0266] An input unit 1606 including a keyboard, a mouse, etc., an output unit 1607 including a display such as a cathode ray tube (CRT) or a liquid crystal display (LCD) and a speaker, etc., a storage 1608 including a hard disk, etc., and a communication unit 1609 including a network interface card such as a LAN card or a modem are connected to the input / output interface 1605. The communication unit 1609 executes communication processing via a network, for example the Internet.
[0267] If necessary, a drive 1610 is also connected to the input / output interface 1605. A removable medium 1611, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is installed in the drive 1610 as necessary, and a computer program read from the removable medium 1611 is installed in the storage 1608 as necessary.
[0268] When the above series of processes is realized by software, the programs constituting the software are installed from a network, such as the Internet, or a storage medium, such as the removable medium 1611 .
[0269] As should be understood by those skilled in the art, such a storage medium is not limited to the removable medium 1611 shown in Fig. 16, which stores the program and is distributed separately from the device to provide the program to the user. Examples of the removable medium 1611 include a magnetic disk (including a floppy disk (registered trademark)), an optical disk (including an optical disk read-only memory (CD-ROM) and a digital versatile disk (DVD)), a magneto-optical disk (including a mini disk (MD) (registered trademark)), and a semiconductor memory. Alternatively, the storage medium may be a ROM 1602, a hard disk included in the storage 1608, etc., in which the program is stored and which is distributed to the user together with the device including the program.
[0270] The techniques of the present disclosure can be applied to a variety of products.
[0271] For example, the controlling electronic device according to the embodiment of the present disclosure may be realized as or included in various control devices / base stations. For example, the transmitting device and the terminal device according to the embodiment of the present disclosure may be realized as or included in various terminal devices.
[0272] For example, the control device / base station mentioned in the present disclosure may be realized as any type of base station, eNB, such as macro eNB and small eNB. The small eNB may be an eNB covering a cell smaller than a macro cell, such as pico eNB, micro eNB and home (femto) eNB. It may also be realized as a gNB, such as macro gNB and small gNB. The small gNB may be a gNB covering a cell smaller than a macro cell, such as pico gNB, micro gNB and home (femto) gNB. Alternatively, the base station may be realized as any other type of base station, such as a NodeB and a base transceiver station (BTS). The base station may include an entity (also called a base station device) arranged to control wireless communication and one or more remote radio heads (RRH) provided at a location different from the entity. In addition, various types of terminals described later can operate as a base station by temporarily or semi-permanently performing base station functions.
[0273] For example, the terminal devices referred to in the present disclosure may be realized in some embodiments as mobile terminals (e.g., smartphones, tablet personal computers (PCs), notebook PCs, portable game consoles, portable / dongle mobile routers, and digital imaging devices) or in-vehicle terminals (e.g., car navigation devices). The terminal devices may be realized as terminals that perform machine-to-machine (M2M) communication (also called machine-type communication (MTC) terminals). In addition, the terminal devices may be wireless communication modules (e.g., integrated circuit modules including a single chip) mounted on each of the above terminals.
[0274] Hereinafter, examples of applications of the present disclosure will be described with reference to the drawings.
[0275] [Base station example] It should be understood that the base station in the present disclosure has the full breadth of its ordinary meaning and includes at least a wireless communication station that is a part of a wireless communication system or a radio system to perform communication. As an example of a base station, for example, the base station may be, but is not limited to, one or both of a base station transceiver station (BTS) and a base station controller (BSC) in a GSM system, one or both of a radio network controller (RNC) and a Node B in a WCDMA system, an eNB in an LTE and LTE-Advanced system, or a corresponding network node in a future communication system (e.g., gNB, eLTEeNB, etc. that may appear in a 5G communication system). Some functions in the base station of the present disclosure may be realized as an entity having a control function for communication in D2D, M2M, and V2V communication scenarios, or as an entity with a function of spectrum coordination in a cognitive radio communication scenario.
[0276] (Example 1) 17 is a block diagram showing a first example of a schematic arrangement of a gNB to which the technology of the present disclosure can be applied. The gNB 1700 includes multiple antennas 1710 and base station equipment 1720. The base station equipment 1720 and each antenna 1710 can be connected to each other via an RF cable. In one implementation, the gNB 1700 (or the base station equipment 1720) here may correspond to the above-mentioned control side electronic device.
[0277] Each of the antennas 1710 includes one or more antenna elements (e.g., multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used by the base station equipment 1720 to transmit and receive wireless signals. As shown in Figure 17, the gNB 1700 may include multiple antennas 1710. For example, the multiple antennas 1710 may be compatible with multiple frequency bands used by the gNB 1700.
[0278] The base station equipment 1720 includes a controller 1721 , a memory 1722 , a network interface 1717 and a wireless communication interface 1725 .
[0279] The controller 1721 may be, for example, a CPU or a DSP, and may operate various functions of the upper layer of the base station device 1720. For example, the controller 1721 may determine location information of a target terminal device among at least one terminal device based on the positioning information of at least one terminal device on the terminal side in the wireless communication system acquired by the wireless communication interface 1725 and the specific location configuration information of the at least one terminal device. The controller 1721 may have logic functions for performing control such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. This control may be performed in combination with a nearby gNB or core network node. The memory 1722 includes a RAM and a ROM, and stores programs executed by the controller 1721 and various types of control data (e.g., a terminal list, transmission power data, and scheduling data).
[0280] The network interface 1723 is a communication interface for connecting the base station equipment 1720 to the core network 1724. The controller 1721 can communicate with a core network node or other gNBs via the network interface 1717. In this case, the gNB 1700 and the core network node or other gNBs can be connected to each other by a logic interface (e.g., an S1 interface and an X2 interface). The network interface 1723 may be a wired communication interface or a wireless communication interface used for a wireless backhaul line. If the network interface 1723 is a wireless communication interface, the network interface 1723 can be used for wireless communication using a higher frequency band than the frequency band used by the wireless communication interface 1725.
[0281] The wireless communication interface 1725 supports any cellular communication scheme (e.g., Long Term Evolution (LTE) and LTE-Advanced) and provides wireless connection to terminals located in the cell of the gNB 1700 via the antenna 1710. The wireless communication interface 1725 may typically include, for example, a baseband (BB) processor 1726 and an RF circuit 1727. The BB processor 1726 may perform, for example, encoding / decoding, modulation / demodulation, multiplexing / demultiplexing, and various types of signal processing of layers (e.g., L1, Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP)). Instead of the controller 1721, the BB processor 1726 may have some or all of the logic functions described above. The BB processor 1726 may be a memory in which a communication control program is stored, or may be a module including a processor and related circuits arranged to execute the program. Program updates may change the functionality of the BB processor 1726. The module may be a card or a chip inserted into a slot of the base station device 1720. Alternatively, the module may be a chip mounted on the card or the chip. At the same time, the RF circuit 1727 may include, for example, a mixer, a filter, and an amplifier, and may transmit and receive radio signals via the antenna 1710. Although FIG. 17 shows an example in which one RF circuit 1727 is connected to one antenna 1710, the present disclosure is not limited to this illustration, and one RF circuit 1727 may be connected to multiple antennas 1710 at the same time.
[0282] As shown in FIG. 17, the wireless communication interface 1725 may include multiple BB processors 1726. For example, the multiple BB processors 1726 may be compatible with multiple frequency bands used by the gNB 1700. As shown in FIG. 17, the wireless communication interface 1725 may include multiple RF circuits 1727. For example, the multiple RF circuits 1727 may be compatible with multiple antenna elements. Although FIG. 17 illustrates an example in which the wireless communication interface 1725 includes multiple BB processors 1726 and multiple RF circuits 1727, the wireless communication interface 1725 may include a single BB processor 1726 or a single RF circuit 1727.
[0283] (Example 2) FIG. 18 is a block diagram showing a second example of a schematic arrangement of a gNB to which the technology of the present disclosure can be applied. The gNB 1800 includes multiple antennas 1810, an RRH 1820, and a base station device 1830. The base station device 1820 and each antenna 1810 can be connected to each other via an RF cable. The base station device 1830 and the RRH 1820 can be connected to each other via a high-speed line of, for example, a fiber cable.
