< first embodiment >

Fig. 1 shows a functional block diagram of an electronic device 100 for wireless communication according to one embodiment of the present disclosure, as shown in fig. 1, the electronic device 100 comprises a processing unit 101, the processing unit 101 being configured to inform only user devices within a coverage area of the electronic device that are traveling towards an obstacle on a passage where the obstacle is located about the obstacle.

The processing unit 101 may be implemented by one or more processing circuits, which may be implemented as a chip, for example.

As an example, in a V2X (information exchange from vehicle to outside, internet of vehicles) scenario, the electronic device 100 may be a base station or a road side device (RSU), the channel may be a lane, and the user device may be disposed on a vehicle within a coverage area of the base station and/or the road side device, for example, the user device may be a car navigation device. As examples, the obstacle may be a barricade, a pedestrian, a non-human creature, an accident venue, and so on. As an example, the channel in which the obstacle is located may include one or more channels.

The processing unit 101 of the electronic device 100 according to the embodiment of the present disclosure, when an obstacle occurs on a lane, notifies only a user device traveling toward the obstacle on the lane where the obstacle is located of information about the obstacle, and thus, frequency reuse in a fixed spatial range can be achieved, for example, a user device traveling toward the obstacle on the lane where the obstacle is located and a user device traveling on a lane adjacent to the lane where the obstacle is located can communicate using the same frequency, thereby saving frequency resources; in addition, since the electronic apparatus 100 does not notify not only the user equipment traveling away from the obstacle on the path on which the obstacle is located but also the user equipment traveling on the path adjacent to the path on which the obstacle is located, of the information about the obstacle, the transmission power of the electronic apparatus 100 is saved, and furthermore, the unrelated user equipment can be prevented from being interfered.

As an example, the processing unit 101 is configured to inform the user equipment about obstacles by beamforming.

When the electronic device 100 according to the embodiment of the present disclosure has an obstacle on a channel, the electronic device informs information about the obstacle by means of beamforming, and it is ensured that the coverage of the beam is limited to only the user equipment traveling toward the obstacle on the channel where the obstacle is located, thereby saving frequency resources and saving the transmission power of the electronic device 100, and furthermore, the irrelevant user equipment can be prevented from being interfered.

As an example, in the V2X scenario, the electronic device 100 according to embodiments of the present disclosure may receive a basic safety message from the user device, the basic safety message including a direction of travel of the user device and a channel in which the user device is located.

The basic security message according to an embodiment of the present disclosure may be constructed as follows.

In the basic safety message according to the embodiment of the present disclosure, "lane info" indicating a lane in which a vehicle in which the user equipment is located and "moving direction" indicating a traveling direction of the vehicle in which the user equipment is located are added as compared to the basic safety message of the related art. Other fields in the basic security message BasicSafetyMessage described above are known to those skilled in the art and therefore will not be described again here. Hereinafter, for the sake of brevity, "vehicle in which the user equipment is located" is sometimes abbreviated as "user equipment", "channel in which the vehicle in which the user equipment is located" is sometimes abbreviated as "channel in which the user equipment is located", and "traveling direction of the vehicle in which the user equipment is located" is sometimes abbreviated as "traveling direction of the user equipment".

The electronic device 100 according to the embodiment of the present disclosure can know the traveling direction of the vehicle in which the user device is located and the passageway in which the vehicle in which the user device is located by receiving the above-described basic safety message from the user device, and thus can inform only the user device traveling toward the obstacle on the passageway in which the obstacle is located of information about the obstacle, and thus, as described above, it is possible to save frequency resources and save transmission power of the electronic device 100.

As a specific embodiment, the electronic device 100 may be a base station, and the processing unit 101 may be configured to broadcast information about the obstacle through the Uu port to user devices traveling towards the obstacle on a passage where the obstacle is located.

As an example, the electronic device 100 may also be provided on the base station side or communicatively connected to a base station, for example. Here, it is also noted that the electronic device 100 may be implemented at the chip level, or also at the device level. For example, the electronic device 100 may operate as a base station itself, and may also include external devices such as memory, transceivers (not shown), and the like. The memory may be used to store programs and related data information that the base station needs to perform to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., user equipment, other base stations, etc.), and implementations of the transceiver are not particularly limited herein.

In the prior art V2X scenario, the base station broadcasts obstacle information to all registered vehicles in the covered area via the Uu port, in such a way that a vehicle traveling away from the obstacle or a vehicle traveling in a lane adjacent to the lane in which the obstacle is located will also receive information about the obstacle, but this information is of low value to these vehicles and, in addition, the transmission power of the base station is high. In the embodiment according to the present disclosure, however, the base station notifies information about the obstacle only to the user equipment traveling toward the obstacle on the tunnel where the obstacle is located, and therefore, frequency reuse in a fixed spatial range can be achieved, thereby saving frequency resources; in addition, since the base station does not notify the user equipment traveling away from the obstacle on the path where the obstacle is located of the information on the obstacle, but does not notify the user equipment traveling on the path adjacent to the path where the obstacle is located of the information on the obstacle, the transmission power of the base station is saved.

As an example, the processing unit 101 may be configured to broadcast information about the obstacle to user devices travelling towards the obstacle on a corridor where the obstacle is located and within a predetermined range from the obstacle. As an example, the predetermined range is preset (for example, preset based on an empirical value). As an example, in the V2X scenario, the processing unit 101 may be configured to broadcast information about the obstacle to user devices traveling towards the obstacle on the aisle where the obstacle is located and being closer to the obstacle. As an example, after the user equipment receives the information about the obstacle, the user equipment closer to the obstacle may collect more accurate detailed information of the obstacle using its own sensor, camera, or the like, and the user equipment receiving the information about the obstacle interacts (shares) the detailed information of the obstacle through the PC5 interface. Since the base station broadcasts information on the obstacle only to user equipments which travel toward the obstacle on a passage on which the obstacle is located and which are within a predetermined range from the obstacle, the transmission power of the base station can be further saved. Further, user devices traveling toward the obstacle on the passageway where the obstacle is located and within a predetermined range from the obstacle can get more information about the obstacle by interacting with the obstacle information.

Further, the user device that received the information about the obstacle transfers (forwards) detailed information of the obstacle to the roadside device associated with the user device and the user device traveling on a passage adjacent to the passage where the obstacle is located, through the PC5 interface.

As an example, the processing unit 101 may be configured to send updated information about obstacles and re-planned path information for the user equipment to the road side device based on detailed information about obstacles reported by the road side device. As an example, in the case that the RSU does not have a large computing power, the RSU summarizes the received detailed information and reports (forwards) the summarized detailed information to the base station through the Uu port. And the server at the base station side calculates the updating information of the obstacles and the re-planned path information based on the summary detailed information reported by the RSU, and sends the updating information and the re-planned path information to the RSU. Then, the RSU sends the updated information and the re-planned path information to the user equipments receiving the information about the obstacles in a multicast manner, so that the user equipments obtain the updated information about the obstacles and the re-planned path information. However, in the case where the RSU has a large calculation capacity, the RSU may calculate a processing time for processing the obstacle and re-planned path information, etc. by itself through, for example, a multiple access edge calculation (MEC) process, and transmit them to the user equipment that received the information on the obstacle through the PC5 interface by multicast without calculating the re-planned path information, etc. by means of the base station.

Fig. 2 shows a schematic diagram of an application scenario of an electronic device for wireless communication in a V2X scenario according to an embodiment of the present disclosure.

In fig. 2, it is assumed that the electronic apparatus 100 is provided on the vehicle side for the base station and the user equipment for the sake of simplifying the description. Fig. 2 shows two adjacent lanes, namely lane 1 and lane 2, wherein an obstacle is present in lane 1. As shown in fig. 2, the base station may notify information about an obstacle with lower power only to vehicles traveling toward the obstacle on lane 1 and closer to the obstacle. Although not explicitly shown in fig. 2, the base station does not notify the vehicle traveling away from the obstacle on the lane 1 of information about the obstacle. As shown in fig. 2, the base station does not notify the vehicle traveling on the lane 2 of the information about the obstacle. Further, as indicated by the double-headed arrow in fig. 2, the vehicle on the lane 1 that receives the information about the obstacle interacts with the information about the obstacle, and as indicated by the single-headed arrow in fig. 2, the vehicle on the lane 1 that receives the information about the obstacle can transmit the information about the obstacle to the vehicle on the lane 2.

Fig. 3 illustrates an information flow regarding notification obstacles between a base station, an RSU, and a User Equipment (UE) in a V2X scenario according to one embodiment of the present disclosure.

As shown in fig. 3, first, the base station broadcasts information about an obstacle to UEs (e.g., UE1 and UE2) traveling toward the obstacle on a path where the obstacle is located at a lower power direction through a Uu port. The UE1 and the UE2 need not acknowledge receipt of the broadcast information, and the UE1 and the UE2 share detailed information of the obstacle through the PC5 interface. And, the UE1 and the UE2 forward detailed information of the obstacle to the RSU through the PC5 interface, and further, although not explicitly shown in fig. 3, the UE1 and the UE2 also forward detailed information of the obstacle to UEs traveling on a lane adjacent to a lane where the obstacle is located through the PC5 interface. The RUS is assumed not to have a large computational capacity, and therefore, the RSU aggregates and forwards the received detailed information to the base station through the Uu port. And the base station calculates updating information of obstacles and re-planned path information based on the detailed information forwarded by the RSU, and sends the updating information and the re-planned path information to the RSU through a Uu port. After confirming the reception of the update information and the re-planned path information through the Uu port, the RSU transmits the update information and the re-planned path information to the UE1 and the UE2 in a multicast manner, so that the UE1 and the UE2 obtain the update information and the re-planned path information.

As another specific embodiment, the electronic device 100 may be a roadside device and the user device is one predetermined user device traveling toward an obstacle on a passageway where the obstacle is located, and the processing unit 101 may be configured to unicast the information about the obstacle to the one predetermined user device through the PC5 interface.

As an example, the electronic device 100 may also be provided on the roadside device side or communicably connected to the roadside device, for example. Here, it is also noted that the electronic device 100 may be implemented at the chip level, or also at the device level. For example, the electronic device 100 may operate as a roadside device itself, and may also include external devices such as a memory, a transceiver (not shown), and the like. The memory may be used to store programs and related data information that the roadside device needs to execute to implement its functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., user equipment, other roadside devices, etc.), and implementations of the transceiver are not particularly limited herein.

In the prior art, limited by the reliability of the transmission power and the used resources, the RSU has a certain limitation of broadcasting the obstacle information through the PC5 port, and the limitation mainly includes the limited coverage range of the signal and the susceptibility of the resources on the direct link to be interfered. In the embodiment according to the present disclosure, however, the roadside device only needs to unicast information about the obstacle to one user device traveling toward the obstacle on the channel where the obstacle is located, and therefore, the roadside device does not need to cover a large range, and the transmission power of the roadside device is saved; furthermore, frequency reuse within a fixed spatial range may also be achieved, thereby saving frequency resources and making resources on the through link less prone to interference.

As an example, the one predetermined user equipment is a user equipment closest to the obstacle. Since the one predetermined user equipment is closest to the obstacle, the user equipment can collect more accurate detailed information of the obstacle using its own sensor, camera, or the like. However, embodiments according to the present disclosure are not limited thereto, and the one predetermined user equipment may be user equipments within a predetermined range from an obstacle. As an example, the predetermined range is preset (for example, preset based on an empirical value).

As an example, in the V2X scenario, the processing unit 101 may be configured to, after receiving an acknowledgement from the one predetermined user equipment confirming receipt of the information about the obstacle, report the acknowledgement to a base station serving the one predetermined user equipment via the Uu port, and report information about a fleet headed by the one predetermined user equipment to the base station.

As an example, the processing unit 101 may be configured to take several user equipments, other than the one predetermined user equipment, of the user equipments traveling on the passageway where the obstacle is located toward the obstacle as members of the fleet, according to the traveling direction of the user equipment and the passageway where the user equipment is located, which are included in the basic safety message received from the user equipment, and report information on the fleet including the head of the fleet and the members to the base station.

As an example, the processing unit 101 may be configured to receive a fleet establishment message from a base station and multicast the fleet establishment message to all user devices included in a fleet. As an example, the processing unit 101, after reporting information on a fleet comprising a fleet head and members to a base station, if a fleet setup message is received from the base station, multicasts the fleet setup message to all user devices comprised in the fleet.

As an example, the head of line in the platoon may be dynamically switched.

As an example, after the fleet is built, the user device that is the head of the fleet notifies other user devices in the fleet of information about obstacles in a multicast manner with minimal delay through the PC5 interface. In this way, the other user devices in the fleet do not need extra consumption to detect whether the obstacle affects the normal traffic of the user devices. Furthermore, the user equipment as the head of the queue supports hybrid automatic repeat request (HARQ) in such a way that other user equipments in the fleet are notified in multicast, thereby improving the accuracy of the transmission.

Fig. 4 illustrates an information flow regarding notification obstacles between a base station, a roadside device and a UE in a V2X scenario according to another embodiment of the present disclosure. In fig. 4, the one predetermined user equipment is denoted by UE 1. The fleet of vehicles includes at least a UE1 and another user equipment UE 2. However, in fig. 4, only the UE1 and the UE2 in the fleet are shown for simplicity of description.

As shown in fig. 4, first, the RSU unicasts information about an obstacle only to a UE1 traveling toward the obstacle on a channel where the obstacle is located through a PC5 interface. The UE1, upon receiving the information, acknowledges receipt of the information about the obstacle to the RSU. The RSU, upon receiving an acknowledgement from the UE1 confirming receipt of the information about the obstacle, reports the acknowledgement to a base station serving the UE1, and reports information to the base station about a fleet of vehicles headed by the UE1, wherein the fleet of vehicles includes at least the UE1 and the UE 2. Then, the base station issues a fleet establishment message to the RSU through the Uu port. The RSU, upon receiving the fleet setup message from the base station, multicasts the fleet setup message to all user devices included in the fleet (in fig. 4, the RSU is shown multicasting the fleet setup message to the UEs 1 and 2). UE1 and UE2 acknowledge to the base station over the Uu port, respectively, after receiving the fleet establishment message. Finally, after the fleet is established, the UE1 informs other user devices in the fleet of information about the obstacle with minimal delay through the PC5 interface in a multicast manner (in fig. 4, the UE1 is shown informing the UE2 of the information about the obstacle). Although not explicitly shown in fig. 4, after the UE2 receives the information about the obstacle from the UE1, the reception of the information about the obstacle is confirmed to the RSU through the PC5 interface.

< second embodiment >

Fig. 5 shows a functional block diagram of an electronic device 200 according to another embodiment of the present disclosure, as shown in fig. 5, the electronic device 200 comprises a processing unit 201, the processing unit 201 being configured to receive information about an obstacle from a base station serving the electronic device 200, wherein the information is broadcast by the base station only to electronic devices traveling towards the obstacle on a corridor in which the obstacle is located.

The processing unit 201 may be implemented by one or more processing circuits, which may be implemented as a chip, for example.

The electronic device 200 may for example be provided on the user device side or be communicatively connected to the user device. Here, it should also be noted that the electronic device 200 may be implemented at the chip level, or may also be implemented at the device level. For example, the electronic device 200 may operate as the user device itself, and may also include external devices such as memory, transceivers (not shown in the figures), and the like. The memory may be used to store programs and related data information that the user device needs to perform to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., base stations, other user equipment, etc.), and implementations of the transceiver are not particularly limited herein.

As an example, in the V2X scenario, the channel may be a lane, the electronic device 200 may be disposed on a vehicle within a coverage of a base station, and the electronic device 200 may be a car navigation device, for example. As examples, the obstacle may be a barricade, a pedestrian, a non-human creature, an accident venue, and so on. As an example, the channel in which the obstacle is located may include one or more channels.

With the electronic apparatus 200 for wireless communication according to the embodiment of the present disclosure, since the information about the obstacle that it receives is broadcast by the base station only to the electronic apparatus traveling toward the obstacle on the passage where the obstacle is located, interference with other electronic apparatuses can be avoided.

As an example, in the V2X scenario, the basic safety message of the electronic device 200 includes a travel direction of the electronic device and a channel in which the electronic device is located. As an example, the electronic device 200 reports the basic security message to the base station. With the above-described basic safety message, the base station can know the traveling direction of the vehicle in which the electronic apparatus 200 is located and the passageway in which the vehicle in which the electronic apparatus 200 is located, so that the base station can notify only the electronic apparatus traveling toward the obstacle on the passageway in which the obstacle is located of information about the obstacle.

In the first embodiment, an example of the basic safety message has been described in detail in connection with the above description, and will not be repeated here.

As an example, the electronic device described above is an electronic device within a predetermined range from an obstacle, and the processing circuit 201 may be configured to: collecting detailed information about the obstacle, and interacting the detailed information with other electronic devices than the electronic device that received the information about the obstacle. As an example, the predetermined range is preset (for example, preset based on an empirical value). As an example, the above-described electronic device may be an electronic device closer to an obstacle. As an example, the above-described electronic apparatus may collect more accurate detailed information of an obstacle using its own sensor, camera, or the like, and interact the detailed information with other electronic apparatuses that receive information about the obstacle through the PC5 interface. Therefore, the above electronic device can obtain more detailed information about the obstacle.

As an example, the processing circuit 201 may be configured to communicate detailed information about the obstacle to road-side devices serving the electronic device 200 and electronic devices traveling on lanes adjacent to the lane in which the obstacle is located through a PC5 interface. Therefore, the roadside apparatus and the electronic apparatus traveling on the passage adjacent to the passage where the obstacle is located can obtain detailed information about the obstacle.

As an example, the processing circuit 201 may be configured to receive at least path information re-planned for the electronic device from the roadside device over the PC5 interface. As an example, the processing circuit 201 may also receive a processing time of a processing obstacle from the roadside device. As an example, the processing circuit 201 may also receive updated information about obstacles from the roadside device. Thus, the electronic device 200 may select the next travel scheme based on the above information.

An example of information flow between the base station, the RSU, and the UE regarding notification obstacles has been described in detail in the first embodiment in conjunction with fig. 3, and will not be repeated here.

< third embodiment >

Fig. 6 shows a functional block diagram of an electronic device 300 according to yet another embodiment of the present disclosure, as shown in fig. 6, the electronic device 300 comprising a processing unit 301, the processing unit 301 being configured to receive information about an obstacle from a roadside device serving the electronic device 300, wherein the information is unicast by the roadside device only to electronic devices traveling towards the obstacle on a aisle where the obstacle is located.

The processing unit 301 may be implemented by one or more processing circuits, which may be implemented as a chip, for example.

The electronic device 300 may for example be provided on the user equipment side or be communicatively connected to the user equipment. Here, it is also noted that the electronic device 300 may be implemented at the chip level, or also at the device level. For example, the electronic device 300 may operate as the user device itself, and may also include external devices such as memory, transceivers (not shown in the figures), and the like. The memory may be used to store programs and related data information that the user device needs to perform to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., roadside devices, other user devices, etc.), and the implementation of the transceiver is not limited in particular herein.

As an example, in the V2X scenario, the channel may be a lane, the electronic device 300 may be disposed on a vehicle within the roadside device coverage, for example, the electronic device 300 may be a car navigation device. As examples, the obstacle may be a barricade, a pedestrian, a non-human creature, an accident venue, and so on. As an example, the channel in which the obstacle is located may include one or more channels.

With the electronic device 300 for wireless communication according to the embodiment of the present disclosure, since the information about the obstacle that it receives is unicast by the roadside device only to the electronic device that travels toward the obstacle on the channel where the obstacle is located, interference with other electronic devices can be avoided.

As an example, the electronic device 300 may be the closest electronic device to the obstacle. As an example, the electronic apparatus 300 may collect detailed information of more accurate obstacles using its own sensor, camera, or the like. However, embodiments according to the present disclosure are not limited thereto, and the electronic apparatus 300 may also be an electronic apparatus within a predetermined range from an obstacle. As an example, the predetermined range is preset (for example, preset based on an empirical value).

As an example, in the V2X scenario, the basic safety message of the electronic device 300 includes a travel direction of the electronic device and a channel in which the electronic device is located. As an example, the electronic device 300 reports the basic safety message to the road side device. With the above-described basic safety message, the roadside apparatus can know the traveling direction of the vehicle in which the electronic apparatus 300 is located and the passage in which the vehicle in which the electronic apparatus 300 is located, so that the roadside apparatus can notify only the electronic apparatus 300 traveling toward an obstacle on the passage in which the obstacle is located, of information about the obstacle.

As an example, in a case where the electronic device 300 is within the coverage of the base station, the roadside device regards the electronic device 300 as a head of the fleet and several electronic devices, other than the electronic device 300, of the electronic devices that travel toward an obstacle on a passageway where the obstacle is located as members of the fleet according to the traveling direction of the electronic device and the passageway where the electronic device is located, which are included in the basic safety message, and reports information on the fleet including the head of the fleet and the members to the base station. As an example, the roadside device receives the fleet establishment message from the base station and multicasts the fleet establishment message to all electronic devices included in the fleet.

As an example, the processing unit 301 may be configured to receive a fleet establishment message from a roadside device in case the electronic device 300 is within the coverage of a base station, wherein the fleet establishment message is received by the roadside device from the base station and in the fleet the electronic device 300 is the head of the fleet and the other electronic devices traveling towards the obstacle on the aisle where the obstacle is located and receiving the fleet establishment message are members, and the processing unit 301 may be configured to notify the members of the information about the obstacle in a multicast manner. The head of the team notifies the members in the fleet of information about the obstacle with minimal delay in a multicast manner so that the members do not need to expend additional effort to detect whether the obstacle affects their normal traffic. In addition, the head of the queue notifies the members in a multicast mode to support HARQ, so that the transmission accuracy is improved.

An example of information flow between the base station, RSU and UE regarding notification of establishment of the fleet of vehicles has been described in detail in the first embodiment in conjunction with fig. 4 and will not be repeated here.

As an example, the processing unit 301 may be configured to broadcast a need to build a fleet of vehicles in which the electronic device 300 is a head of the fleet and other electronic devices are members to other electronic devices traveling on a corridor towards an obstacle if the electronic device 300 is not within the coverage of a base station, and the processing unit 301 may be configured to notify the members of information about the obstacle in a multicast manner. After the fleet is built, the head of the fleet notifies the members in the fleet of information about obstacles in a multicast manner with minimal delay so that the members do not need to expend additional effort to detect whether an obstacle affects their normal traffic. In addition, the head of the queue notifies the members in a multicast mode to support HARQ, so that the transmission accuracy is improved.

As an example, the head of line in the platoon may be dynamically switched.

As an example, when a fleet is built, members need to interact with the head of the fleet to assist the head of the fleet in determining whether it is possible to safely pass through the passage where the obstacle is located through the field of the related vehicle information in the basic safety message.

As an example, the processing unit 301 may be configured to notify the member unable to pass through the channel in a unicast manner to re-perform the path planning when the member unable to pass through the channel is found to be included in the fleet. As an example, when the head of the team finds that a member in the fleet is included who cannot pass through the passage where the obstacle is located, for example because of a large volume, the head of the team informs the member of the need for re-routing in a unicast manner through the PC5 interface. When the member receives the information that the path planning needs to be performed again, it needs to first judge whether the member is in the coverage area of the base station. If the member is in the coverage area of the base station, the member requests the server at the base station side for re-path planning, and the server at the base station side recalculates the path planning and updates the new path planning to the member. And if the member is not in the coverage range of the base station, the member updates the path plan of the member through the information collected by the sensor of the member and the information interacted with other electronic equipment.

Furthermore, information about the obstacle may be directionally broadcast by electronic devices traveling on lanes adjacent to the lane in which the obstacle is located to electronic devices traveling toward the obstacle when the lane in which the obstacle is located is not covered by the RSU or base station. As an example, an electronic device traveling on a passage adjacent to a passage where an obstacle is located acquires information on the obstacle through its own sensor, camera, or the like, or acquires information on the obstacle through Uu communication of a cellular network. As an example, the above-described basic safety message is interacted between the electronic devices, and the electronic device traveling on a passage adjacent to a passage where the obstacle is located broadcasts information about the obstacle to the electronic device traveling toward the obstacle on the passage where the obstacle is located based on the basic safety message.

[ application example with respect to base station ]

(first application example)

Fig. 10 is a block diagram illustrating a first example of a schematic configuration of an eNB or a gNB to which the techniques of this disclosure may be applied. Note that the following description takes an eNB as an example, but may be applied to a gNB as well. eNB 800 includes one or more antennas 810 and base station equipment 820. The base station device 820 and each antenna 810 may be connected to each other via an RF cable.

Each of the antennas 810 includes a single or multiple antenna elements, such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna, and is used for the base station apparatus 820 to transmit and receive wireless signals. As shown in fig. 10, eNB 800 may include multiple antennas 810. For example, the multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Although fig. 10 shows an example in which the eNB 800 includes multiple antennas 810, the eNB 800 may also include a single antenna 810.

The base station device 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

The controller 821 may be, for example, a CPU or a DSP, and operates various functions of higher layers of the base station apparatus 820. For example, the controller 821 generates a data packet from data in a signal processed by the wireless communication interface 825 and transfers the generated packet via the network interface 823. The controller 821 may bundle data from a plurality of baseband processors to generate a bundle packet, and deliver the generated bundle packet. The controller 821 may have a logic function of performing control as follows: such as radio resource control, radio bearer control, mobility management, admission control and scheduling. The control may be performed in connection with a nearby eNB or core network node. The memory 822 includes a RAM and a ROM, and stores programs executed by the controller 821 and various types of control data (such as a terminal list, transmission power data, and scheduling data).

The network interface 823 is a communication interface for connecting the base station apparatus 820 to a core network 824. The controller 821 may communicate with a core network node or another eNB via a network interface 823. In this case, the eNB 800 and a core network node or other enbs may be connected to each other through a logical interface, such as an S1 interface and an X2 interface. The network interface 823 may also be a wired communication interface or a wireless communication interface for a wireless backhaul. If the network interface 823 is a wireless communication interface, the network interface 823 may use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 825.

The BB processor 826 may have a part or all of the above-described logic functions in place of the controller 821. The BB processor 826 may be a memory storing a communication control program, or a module including a processor configured to execute a program and related circuitry. The update program may cause the function of the BB processor 826 to change. The module may be a card or blade that is inserted into a slot of the base station device 820. Alternatively, the module may be a chip mounted on a card or blade. Meanwhile, the RF circuit 827 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive a wireless signal via the antenna 810.

As shown in fig. 10, wireless communication interface 825 may include a plurality of BB processors 826. For example, the plurality of BB processors 826 may be compatible with the plurality of frequency bands used by the eNB 800. As shown in fig. 10, wireless communication interface 825 may include a plurality of RF circuits 827. For example, the plurality of RF circuits 827 may be compatible with a plurality of antenna elements. Although fig. 10 shows an example in which the wireless communication interface 825 includes a plurality of BB processors 826 and a plurality of RF circuits 827, the wireless communication interface 825 may include a single BB processor 826 or a single RF circuit 827.

In the eNB 800 shown in fig. 10, the transceiver of the electronic device 100 may be implemented by the wireless communication interface 825. At least a portion of the functionality may also be implemented by the controller 821.

The wireless communication interface 855 supports any cellular communication scheme (such as LTE and LTE-advanced) and provides wireless communication via the RRH 860 and the antenna 840 to terminals located in a sector corresponding to the RRH 860. The wireless communication interface 855 may generally include, for example, the BB processor 856. The BB processor 856 is identical to the BB processor 826 described with reference to fig. 10, except that the BB processor 856 is connected to the RF circuit 864 of the RRH 860 via a connection interface 857. As shown in fig. 11, wireless communication interface 855 may include a plurality of BB processors 856. For example, the plurality of BB processors 856 may be compatible with the plurality of frequency bands used by the eNB 830. Although fig. 11 shows an example in which wireless communication interface 855 includes multiple BB processors 856, wireless communication interface 855 may include a single BB processor 856.

The RF circuit 864 may include, for example, mixers, filters, and amplifiers, and transmits and receives wireless signals via the antenna 840. As shown in fig. 11, wireless communication interface 863 may include a plurality of RF circuits 864. For example, the plurality of RF circuits 864 may support a plurality of antenna elements. Although fig. 11 illustrates an example in which the wireless communication interface 863 includes multiple RF circuits 864, the wireless communication interface 863 may include a single RF circuit 864.

In the eNB 830 shown in fig. 11, the transceiver of the electronic device 100 may be implemented by the wireless communication interface 825. At least a portion of the functionality may also be implemented by the controller 821. For example, the controller 821 may notify user devices within a coverage area traveling toward an obstacle on a passage where the obstacle is located, of information about the obstacle by performing the function of the processing unit 101.
