Description

Method for waking up a device and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 23, 2023, with application number 202311580854.7 and application name “A Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] As fifth-generation (5G) mobile communication systems evolve toward 5G-advanced (5G-A) technology, communication sensing technology is considered a key technology for expanding the service capabilities of mobile communication networks. The core concept of this communication sensing technology is to add sensing capabilities to mobile communication networks, building capabilities such as target detection, tracking, and imaging. This allows communication and sensing capabilities to coexist harmoniously and benefit each other within a single network. The principle of sensing technology is that a transmitting device sends radio waves (i.e., sensing signals) in a specific direction. When these radio waves strike the target surface, they generate reflected radio waves (i.e., echo signals of the sensing signals). The receiving device then receives and processes these reflected waves to obtain sensing data, such as the target's location, speed, or type.

[0004] Currently, communication frames are scheduled using time slots, as shown in Figure 1 below. A time slot is a continuous period of time. In 5G NR systems, a time slot consists of 14 OFDM symbols. A 15kHz subcarrier spacing corresponds to a time slot length of 1ms, while a 30kHz subcarrier spacing corresponds to a time slot length of 0.5ms. Whether the base station sends signals to the terminal or the terminal sends signals to the base station, the time slot is used as a unit. This short duration results in low speed perception resolution when communication and perception signals are multiplexed, making it difficult to perceive slower targets.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus, which are conducive to achieving an optimal compromise between communication performance and perception performance.

[0007] In a first aspect, the present application provides a communication method, which can be performed by a first communication device. The first communication device can be, for example, a first network device, or a component in a network device, without limitation. Taking the execution subject as the first network device as an example, the method includes: the first network device sends first indication information to a terminal device, the first indication information indicating information of a first time segment, a second time segment, and a third time segment, the first time segment and the second time segment respectively occupying time segments in the first time segment, and the third time segment includes at least part of the time segments of each of the second time segments in multiple first time segments; the first network device sends second indication information to the terminal device, the second indication information indicating that the first signal occupies the first time segment or occupies the second time segment.

[0008] In an embodiment of the present application, the communication and perception multiplexing frame structure includes multiple first time periods, each of which may include a first time segment and a second time segment. At least a portion of each second time segment in the multiple first time segments is selected to form a third time segment. In this way, the signal scheduled in the first time segment only occupies a time segment in one first time segment. Since the signal scheduled in the second time segment can be indicated using the third time segment, it can occupy time segments in multiple first time segments. As a result, the signals scheduled by the first network device or the second network device in multiple second time segments can simultaneously schedule more resources at once, thereby improving scheduling efficiency.

[0015] In one possible design, the first time period is a time slot, and the first time segment and the second time segment are time slot parts.

[0016] The frame structure of communication and perception multiplexing contains two time slot parts. The signal scheduled in the first time slot part only occupies the symbols of one time slot, and the signal scheduled in the second time slot part needs to occupy the symbols of multiple time slots, thereby achieving high perception efficiency.

[0089] In the embodiment of the present application, the functions of the terminal device may also be performed by a module (such as a chip or a modem) in the terminal device, or may be performed by a device that includes the functions of the terminal device.

[0090] Network devices and terminal devices can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; and in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of network devices and terminal devices.

[0091] The roles of network devices and terminal devices can be relative. For example, the helicopter or drone 120i in Figure 2 can be configured as a mobile network device. For terminal devices 120j accessing the wireless access network 100 via 120i, terminal device 120i is a network device. However, for network device 110a, 120i is a terminal device, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via an interface protocol between network devices. In this case, 120i is also a network device relative to 110a. Therefore, both network devices and terminal devices can be collectively referred to as communication devices. 110a and 110b in Figure 2 can be referred to as communication devices with network device functionality, while 120a-120j in Figure 2 can be referred to as communication devices with terminal device functionality.

[0092] Network devices and terminal devices, network devices and network devices, and terminal devices and terminal devices can communicate through licensed spectrum, through unlicensed spectrum, or through both licensed and unlicensed spectrum at the same time, without any restrictions.

[0093] The transmitting device in the embodiment of the present application refers to the transmitting end of the perception signal or communication signal, and the receiving device refers to the receiving end of the echo signal of the perception signal or communication signal. It can be understood that the roles of the transmitting device and the receiving device can be interchangeable, that is, the transmitting device also has the receiving capability, and the receiving device also has the transmitting capability. For example, the transmitting device can be the network device in Figure 2, and the receiving device can be the terminal device in Figure 2; or, the transmitting device can be the terminal device in Figure 2, and the receiving device can be the network device in Figure 2; or, the transmitting device and the receiving device are the network devices in Figure 2; or, the transmitting device and the receiving device are the terminal devices in Figure 2, without limitation.

[0094] Next, the technical features involved in the embodiments of this application are introduced.

[0095] Perception technology can generally be divided into two modes: single-station perception and dual-station perception.

[0096] Single-station sensing mode refers to a situation where the device that transmits the sensing signal and receives the echo signal of that sensing signal is the same device. In other words, in single-station sensing mode, the transmitting device must both transmit the sensing signal and receive the echo signal reflected from the target surface. Therefore, this single-station sensing mode can also be referred to as a self-transmitting and self-receiving mode, without limitation.

[0097] In a dual-station sensing mode, the sensing signal transmitter and the echo receiver are two different devices. In other words, sensing station A transmits the sensing signal, and the echo signal reflected from the target surface is received by sensing station B. Therefore, this dual-station sensing mode can also be referred to as the A-transmit, B-receive mode.

[0098] Figure 3 provides a schematic diagram of the perception scenarios applicable to the embodiments of the present application. Figure 3 provides six perception scenarios, namely, the scenario in which network device A sends and receives signals by itself, as shown in (1) in Figure 3; the scenario in which terminal device A sends and receives signals by itself, as shown in (2) in Figure 3; the scenario in which network device A sends a perception signal and network device B receives an echo signal, as shown in (3) in Figure 3; the scenario in which terminal device A sends a perception signal and terminal device B receives an echo signal, as shown in (4) in Figure 3; the scenario in which network device A sends a perception signal and terminal device A receives an echo signal, as shown in (5) in Figure 3; the scenario in which terminal device A sends a perception signal and network device A receives an echo signal, as shown in (6) in Figure 3. The embodiments of the present application focus on the scenario in which network device A sends a perception signal and network device B receives an echo signal, and the two scenarios in which network device A sends a perception signal and the terminal device receives an echo signal.

[0099] It should be noted that although FIG3 shows a vehicle as the sensing target, the present embodiment is not limited to this. For example, the sensing target can also be a pedestrian, a low-altitude drone, or other moving or stationary objects. FIG3 shows a smartphone as the terminal device, the present embodiment is not limited to this.

[0100] In wireless communication systems, communications can be divided into different types according to the types of sending nodes and receiving nodes. Generally, sending information from a network device to a terminal device is called downlink communication, and sending information from a terminal device to a network device is called uplink communication. In Long Term Evolution (LTE) / Long Term Evolution Advanced (LTE-A) communication systems and New RAT (NR) systems, communications can be mainly divided into Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode according to the different duplex modes. For wireless communication systems operating in TDD mode, the downlink carrier and uplink carrier of the system are carriers of the same carrier frequency. The multiple access method usually adopts Orthogonal Frequency Division Multiplexing Access (OFDMA) method. The main feature of OFDMA is that it divides transmission resources into mutually orthogonal time-frequency resource elements (REs). The signals sent by the transmitter are all carried on the REs and transmitted to the receiver. Because different REs are orthogonal to each other, the receiver can receive the signals sent on each RE separately.

[0101] Figure 4 shows a flow chart of a communication method provided by an embodiment of the present application. As shown in Figure 4, the method may include the following contents.

[0102] S401. The first network device can determine a first time segment, a second time segment, and a third time segment, wherein the first time segment and the second time segment are respectively time segments occupied in the first time period, and the third time segment includes at least part of the time segment of each second time segment in multiple first time periods.

[0103] Optionally, the first time period may be a specific time period, such as 1ms, 0.5ms, 0.25ms, etc.; or it may be a predefined time unit. The predefined time unit may be agreed upon by the protocol or preconfigured, and this application does not limit this. Exemplarily, it may be one or more symbols, or one or more time slots, or one or more mini-slots, or one or more subframes, or one or more frames, etc. The embodiments of this application do not limit the time domain granularity. Taking 5G NR as an example, a time slot includes 14 symbols, so the first time period may be a time slot including 14 symbols. In subsequent standards, the same concepts as 4G and 5G may continue to be used, or newly named time units may be used.

[0104] In implementation method 1, the first time segment and the second time segment each occupy consecutive time segments within the first time period. For example, when the first time period is 1 ms, the first time segment may be the first 0.5 ms of the 1 ms, and the second time segment may be the last 0.5 ms of the 1 ms. Generally, the first time segment is t ms within the 1 ms, and the second time segment is 1-t ms within the 1 ms. For another example, when the first time period includes 14 symbols, the first time segment may occupy the first M symbols of the 14 symbols, and the second time segment may occupy the last 14-M symbols of the 14 symbols. Optionally, the first time segment may also be the last M symbols of the first time period, and the second time segment may be the first 14-M symbols of the first time period, but this is not limited here.

[0105] Implementation method two, the first time segment and the second time segment respectively occupy discontinuous time segments in the first time period. For example, when the first time period is 1ms, the first time segment may be the first 0.4ms of the 1ms, and the second time segment may be the last 0.4ms of the 1ms; generally, the first time segment is t1ms in the 1ms, and the second time segment is t2ms in the 1ms, t1+t2<1. For another example, when the first time period includes 14 symbols, the first time segment may occupy the first M1 symbols of the 14 symbols, and the second time segment occupies the last M2 symbols of the 14 symbols, M1+M2<14. Optionally, the first time segment may also be the last M2 symbols of the first time period, and the second time segment may be the first M1 symbols of the first time period, M1+M2<14, which is not limited here.

[0106] Furthermore, the wireless frame may include multiple first time periods, and each first time period may be configured to include both the first time segment and the second time segment; optionally, some first time periods may be configured to include only the first time segment, and some time periods may include both the first time segment and the second time segment. Generally speaking, the number of second time segments included in multiple first time periods is at least 2.

[0107] Optionally, when the second time segment is a time unit, the third time segment may include at least one time unit in each second time segment, and each third time segment may include K time units. For example, the time unit may be a symbol, multiple symbols, or other types of time units. Considering that the first time segment and the second time segment each occupy a portion of symbols in a time slot, the first time segment and the second time segment may be referred to as a slot part (SP).

[0108] The frame structure for setting communication and perception multiplexing includes two time slot parts. The signal scheduled in the first time slot part only occupies the symbols of one time slot, and the signal scheduled in the second time slot part needs to occupy the symbols in multiple time slots, thereby achieving high perception efficiency.

[0109] The third time segment includes at least a portion of each of the second time segments in the plurality of first time segments, and generally includes at least two second time segments, that is, the third time segment includes a portion of each of the at least two second time segments. For example, as shown in FIG6 , a total of three first time segments, three first time segments, three second time segments, and two third time segments are included, wherein each first time segment includes 14 symbols, each first time segment includes 12 symbols, each second time segment includes 2 symbols, and each third time segment includes 3 symbols from the three second time segments.

[0110] In implementation method 1, the time unit may be a symbol, the first time segment includes a portion of the symbol, the second time segment includes a portion of the symbol, and the plurality of first time segments include a total of M2 second time segments. For example, as shown in FIG7 , when the second time segment includes 7 symbols, the three second time segments may include 7 third time segments, where the first third time segment is composed of the first symbol of each of the three second time segments, the second third time segment is composed of the second symbol of each of the three second time segments, and so on.

[0111] In a second implementation, the time unit may be multiple symbols, the first time segment includes a portion of the symbols, the second time segment includes a portion of the symbols, and the multiple first time segments include a total of three second time segments. For example, as shown in FIG8 , when the second time segment includes eight symbols, the three second time segments may include four third time segments, where the first third time segment is composed of the first to second symbols of each of the three second time segments, the second third time segment is composed of the third to fourth symbols of each of the three second time segments, and so on.

[0112] Implementation method three: When the second time segment is a specific time segment, the third time segment includes K partial time segments. For example, the specific time segment of the second time segment may be 0.7 seconds, which can be divided into 7 more specific time segments, each of which is 0.1 seconds. Then, M2 second time segments can contain 7 third time segments, where the first third time segment consists of the first 0.1 seconds of each of the M2 second time segments, the second third time segment consists of the second 0.1 seconds of each of the M2 second time segments, and so on.

[0113] In implementation method 4, the time units or specific time segments extracted (selected) from the second time segment each time can be continuous or discontinuous. For example, as shown in FIG9 , when the second time segment includes 7 symbols, then the three second time segments can include 4 third time segments, where the first third time segment is composed of the first symbol of each of the three second time segments, the second third time segment is composed of the third symbol of each of the three second time segments, and so on, that is, extraction is performed at odd symbol positions.

[0114] In implementation method five, the positions of the time units or specific time segments extracted (selected) from the second time segment each time may correspond or may not correspond. For example, as shown in FIG10 , when the second time segment includes 7 symbols, the three second time segments may include 6 third time segments, where the first time segment is composed of the first symbols of the first and second second time segments and the second symbol of the third second time segment among the three second time segments, the second time segment is composed of the second symbols of the first and second second time segments and the third symbol of the third second time segment, and so on.

[0115] Therefore, the number, location, and correspondence of the time units or specific time segments of each second time segment included in the third time segment can be implemented in a variety of ways and are not limited here. It can be seen that the implementation of the first time segment, the second time segment, and the third time segment is flexible and can be applied to different communication or perception scenarios.

[0116] S402. The first network device sends first indication information to the terminal device, where the first indication information indicates information of the first time segment, the second time segment, and the third time segment.

[0117] Correspondingly, the terminal device receives the first indication information sent from the first network device.

[0118] Optionally, the first indication information indicates the number of time units or the absolute time length contained in the first time segment, the number of symbols or the absolute time length contained in the second time segment, and the number of time units or the absolute time length occupied by the third time segment. Specifically, the first indication information may include three fields. When the first time period is a specific time period, the first indication information indicates the absolute time length contained in the first time segment, the absolute time length contained in the second time segment, and the absolute time length contained in the third time segment. When the first time period is a predefined time unit, the first indication information indicates the number of time units contained in the first time segment, the number of time units contained in the second time segment, and the number of time units contained in the third time segment. For example, the first field indicates the number of symbols in the first time segment, the second field indicates the number of symbols in the second time segment, and the third field indicates the number of symbols contained in the third time segment.

[0119] Optionally, the first indication information indicates the number of time units or the absolute time length contained in the first time segment, the number of symbols or the absolute time length contained in the second time segment, and / or the number of time units occupied by the third time segment. Specifically, the rule for the third time segment to select a time segment from the second time segment can be predefined. For example, the third time segment can be predefined as extracting (selecting) each time segment in each second time segment one by one. The first indication information may include three fields. When the first time period is a specific time period, the first indication information indicates the absolute time length contained in the first time segment, the absolute time length contained in the second time segment, and the third time segment can be reserved or can also indicate the extraction rule; when the first time period is a predefined time unit, the first indication information indicates the number of time units contained in the first time segment, the number of time units contained in the second time segment, and / or the number of time units occupied by the third time segment, or can also indicate the extraction rule.

[0120] Furthermore, the first indication information may indicate the position of the time unit included in the first time segment, the position of the time unit included in the second time segment, and / or the position of the time unit occupied by the third time segment. Specifically, the first indication information may include three fields, the first field indicating the symbol position of the first time segment, the second field indicating the symbol position of the second time segment, and the third field indicating the symbol position included in the third time segment.

[0121] Furthermore, considering that not all first time periods include the second time segment, as shown in FIG11 , the second first time period does not include the second time segment, the first indication information may further include a field indicating the first time period including the second time segment. For example, the first indication information includes a fourth field, and the fourth field indicates the period and offset of the first time period including the second time segment. For example, if the period of the first time period is 2, 4, or another value, it can be understood that one first time period includes the second time segment for every two or four first time periods; when the period is 2, the offset can be 0 or 1, where 0 indicates that the first time period with an even number includes the second time segment, and 1 indicates that the first time period with an odd number includes the second time segment. Of course, the reverse is also possible.

[0122] Optionally, the first indication information may be carried in broadcast information and sent by the base station to the terminal, or may be carried in a system information block (SIB) or carried in radio resource control RRC layer signaling.

[0123] S403. The first network device sends second indication information to the terminal device, where the second indication information indicates that the first signal occupies the first time segment or the second time segment.

[0124] Correspondingly, the terminal device receives the second indication information sent from the first network device.

[0125] Furthermore, the second indication information instructs the first network device to send a first signal to the terminal device, or instructs the terminal device to send a first signal to the first network device.

[0126] Specifically, the second indication information includes a fifth field, which can be 1 bit. State 0 indicates that the first signal occupies the first time segment, and state 1 indicates that the first signal occupies the second time segment; or state 1 indicates that the first signal occupies the first time segment, and state 0 indicates that the first signal occupies the second time segment.

[0127] Furthermore, the second indication information also includes a sixth field. When the fifth field indicates that the first signal occupies the first time segment, the sixth field indicates the position of the time unit in the first time segment occupied by the first signal; when the fifth field indicates that the first signal occupies the second time segment, the fifth field indicates the position of the time unit contained in the third time segment in the second time segment occupied by the first signal.

[0128] Furthermore, when the time unit is a symbol, when the fifth field indicates that the first signal occupies the first time segment, the sixth field indicates the symbol position in the first time segment occupied by the first signal; when the fifth field indicates that the first signal occupies the second time segment, the fifth field indicates the symbol position contained in the third time segment in the second time segment occupied by the first signal.

[0129] For example, the sixth field may contain 4 bits for a total of 16 states. When indicating the symbol position in the first time segment, there may be 16 states, while when indicating the symbol position in the second time segment, there may be less than 16 states, such as 12, 8, etc. That is, the number of bits of the fifth field depends on the larger number of states in the two cases.

[0130] Table 1 Sixth field design example

[0131] If the first time segment contains 10 symbols and the second time segment contains 4 symbols, the sixth field may contain 4 bits, which may indicate a total of 16 states. If the indication is of the symbol position of the first time segment occupied by the first signal, a design method is shown in Table 1. If the indication is of the symbol position of the second time segment occupied by the first signal, it may correspond to the previous four states. It should be noted that each state may correspond to the position of one or more symbols used, and may have other defined methods other than those in the table, which are not limited here.

[0132] Optionally, the second indication information carries downlink control information (DCI), which is sent by the network device to the terminal device.

[0133] Furthermore, the first signal may be used for perception and / or communication, but is not limited thereto.

[0134] S404: The first network device sends a first signal to the terminal device, or the first network device receives a first signal from the terminal device.

[0135] The communication and perception multiplexing frame structure includes multiple first time periods, each of which may include a first time segment and a second time segment. At least a portion of the second time segments in the multiple first time segments are extracted (selected) to form a third time segment. In this way, the signal scheduled in the first time segment only occupies a time segment in the first time segment. Since the signal scheduled in the second time segment can be indicated using the third time segment, it can occupy time segments in multiple first time segments. As a result, the signals scheduled by the first network device or the second network device in multiple second time segments can simultaneously schedule more resources, thereby improving scheduling efficiency.

[0136] The frame structure that multiplexes communication and perception can achieve the optimal compromise between communication performance and perception performance, improve the efficiency of scheduling communication signals or perception signals, and enable perception signals to perceive targets at higher speeds, thereby enhancing perception capabilities.

[0142] For the specific implementation process of S502, please refer to the relevant content of S402 and will not be repeated here.

[0143] S503: The first network device sends second indication information to the second network device, where the second indication information indicates whether the first signal occupies the first time segment or the second time segment.

[0146] S504: The first network device sends a first signal to the second network device, or the first network device receives a first signal from the second network device.

Whether a function of the above-mentioned functions is performed in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

[0148] The following describes the communication device used to implement the above method in the embodiment of the present application with reference to the accompanying drawings. Therefore, the above contents can be used in subsequent embodiments, and repeated contents will not be repeated.

[0149] Fig. 12 exemplarily shows a schematic structural diagram of a communication device 1200. The communication device 1200 can implement the functions or steps implemented by the first communication device or the second communication device in the above-mentioned various method embodiments.

[0151] It should be noted that the communication device 1200 may include the processing module 1201 but not the transceiver module 1202. Alternatively, the communication device 1200 may include the transceiver module 1202 but not the processing module 1201. The specific implementation depends on whether the above solution executed by the communication device 1200 includes both processing and transceiver actions.

[0152] Optionally, the communication device 1200 may further include a storage module, which is not shown in Figure 12.

The communication device 1200 can be the first communication device or the second communication device, or can also be a component configured in the first communication device or the second communication device. The processing module 1201 is configured to perform processing-related operations on the first communication device or the second communication device in the above-described method embodiments. The transceiver module 1202 is configured to perform transceiver-related operations on the first communication device or the second communication device in the above-described method embodiments.

[0159] In a possible implementation, the processing module 1201 may be configured to determine a first time segment, a second time segment, and a third time segment.

[0160] It should be understood that a more detailed description of the execution of the corresponding process by each module can be directly obtained by referring to the relevant description in any of the method embodiments shown in Figures 4 to 5. For the sake of brevity, it is not repeated here.

[0161] As shown in Figure 13, an embodiment of the present application provides a schematic structural diagram of a communication device 1300. The communication device 1300 may include a processor 1320 for implementing or supporting the communication device 1300 in implementing the functions of the first communication device or the second communication device in any method embodiment of the present application. For details, please refer to the detailed description of the aforementioned method embodiment, which is not repeated here. For example, the processor 1320 is used to read and execute program instructions through a communication interface to enable the communication device 1300 to implement the corresponding method. The processor 1320 may include one or more processors without limitation.

[0162] Specifically, the communication device 1300 can be a first communication device or a functional module located in the first communication device, which can implement the function of the first communication device in any method embodiment of the present application; or, the communication device 1300 can be a second communication device or a functional module located in the second communication device, which can implement the function of the second communication device in any method embodiment of the present application.

[0163] It should be noted that the above-mentioned functional modules can be implemented by hardware or by a combination of hardware and software without limitation.

[0164] For example, the communication device 1300 may be a chip system, wherein the chip system may be composed of a chip, or may include a chip and other discrete components, without limitation.

[0165] Optionally, communication device 1300 may further include memory 1330 for storing program instructions and / or data. Memory 1330 is coupled to processor 1320. Coupling can be understood as an indirect coupling or communication connection between devices, units, or modules, which can be electrical, mechanical, or other forms, for information exchange between devices, units, or modules. Processor 1320 may operate in conjunction with memory 1330. Memory 1330 may include one or more memories, without limitation.

[0166] Furthermore, the processor 1320 is configured to execute program instructions stored in the memory 1330 so that the communication device 1000 implements a corresponding method.

[0167] One or more memories in memory 1330 may be included in the processor, or memory 1330 may exist independently, such as an off-chip memory, and be connected to processor 1320 via a communication bus (represented by a thick line 1340 in FIG. 13 ). Memory 1330 and processor 1320 may also be integrated together.

[0168] Optionally, the communication device 1300 further includes a communication interface 1310 (indicated by a dotted line in FIG. 13 ) for communicating with other devices via a transmission medium, thereby enabling the device in the communication device 1300 to communicate with the other device. For example, when the communication device is a first communication device, the other device may be a second communication device, etc. The processor 1320 may use the communication interface 1310 to send and receive data.

[0169] The communication interface 1310 may be a transceiver. In hardware implementation, the transceiver may be used to implement the functions of the transceiver module 1402 . The transceiver is integrated into the communication device 1300 to form the communication interface 1310 .

[0170] It should be noted that the specific connection medium between the communication interface 1310, processor 1320, and memory 1330 is not limited in the embodiments of the present application. In FIG13 , the memory 1330, processor 1320, and communication interface 1310 are connected via a communication bus 1340. The connection methods between other components are merely schematic and not limiting. The communication bus 1340 can be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, FIG13 shows only one thick line, but this does not mean that there is only one communication bus or only one type of communication bus.
